US Classification:
237 1A
Abstract:
A parapet-like component for a building which includes an air plenum. The plenum is a multipurpose structure which allows for transfer of a predetermined amount of heat from the outside into the building. The plenum includes translucent surfaces which allow light to enter the building and concurrently provide insulation against loss of heat from within the building towards the outside. The parapet-like component can be operated reversibly in allowing for cooling of the interior of the building when its temperature exceeds that of the outside. The structure is highly functional and also is aesthetically pleasing, having the general appearance of a mansard. The novel design of the invention allows for and incorporates the use of traditional and widely accepted building and architectural practices and esthetics. In a preferred embodiment, the plenum has an exterior wall of a tinted plastic or glass and a clear inside wall of plastic or glass. The structure is relatively easy to conform to conventional architectural plans.
Apparatus For Area Measurement Of Elongated Strips

International Classification:
G01B 732
US Classification:
33123
Abstract:
Apparatus for area measurement of elongated strips of different widths is described, which strips may be film to be treated, the strips to be measured being delivered manually or driven between rolls carried on parallel shafts, the number of rolls on one shaft which are actuated being determined by the width of the strips, the actuation rolls having magnets carried therein to activate switches to generate pulses for counting by a counter to give an area indication. The actuation rolls are preferably counterbalanced to reduce undesired movement.
Automatic Material Splicer For Photographic Materials

International Classification:
B32B 3100 B65H 1908 G03D 1504
US Classification:
156361
Abstract:
An automatic splicer is provided which is coupled to a continuous running processor. Short strips of roll film are inserted into the splicer and are automatically spliced together as they are advanced through the splicer. When no film is ready to be processed a leader is automatically spliced to the last roll of film to be processed. When the last roll of film is passed through the processor, the system may be placed on standby or stopped.

International Classification:
B01F 506
US Classification:
366337
Abstract:
Tanks for mixing apparatus are described in which one or more chemical materials are to be incorporated in a carrier liquid, which may be a solvent, such as water, and which is quantitatively predominant, some of the chemical materials being incompatible if brought together directly, or in a wrong sequence, or which are difficult to combine, the materials preferably being combined in the desired proportions in a cascaded arrangement of liquid filled chambers, the respective materials in the desired proportions preferably being supplied from separate sources of materials by pumps, the delivery of the carrier liquid being to a first mixing chamber in the tank to which a first chemical material is supplied, additional and successive mixing chambers being provided, if desired, the tanks being constructed of synthetic plastic material molded to provide a body to receive partition walls for attachment to the body, and a cover preferably transparent and molded to receive the partition walls, the cover preferably having fluid connections thereon for fluid and chemical material supply, for agitation of the liquid in the chambers for mixing for delivery of the mixed materials for use. Improved methods of making the tanks are also disclosed.
Conveyor Apparatus For Processing Photographic Materials

International Classification:
B65H 1722
US Classification:
226 91
Abstract:
Conveyor apparatus for processing photographic materials is disclosed and more specifically equipment for turnaround during processing of an elongated web of photographic material at the midportion of a processing operation, a plurality of parallel inner and outer driven rollers being employed to receive and direct the web for turnaround, the outer rollers being disposed at spaced locations along the outside of the turnaround path, the inner rollers also being disposed along the inside of the turnaround path and being spaced from and having their axes offset from a radial plane through the outer rollers and the center of the turnaround path, the inner and outer rollers being disposed for advancing the web without pinching of the web and free from contact with fixed guides which tend to scratch or mar the surface being processed, an improved and compact drive being provided particularly for the inner rollers.

International Classification:
B65H 100
US Classification:
271162
Abstract:
Apparatus for feeding small and large X-ray film and the like to processing machines is disclosed which includes an entrance section contiguous to infeed rolls of the processing machine, which can receive the film, and which has a movable closure and a chute movable into a feeding position with respect to the entrance section when the closure is in an open position, the chute having a closure and being of a length to accommodate the large film as it is advanced by the infeed rolls.

International Classification:
F04B 4902
US Classification:
417 40
Abstract:
Control apparatus is provided responsive to liquid flow which has in the suction line of the pump a float operated magnetically actuated switch in which the float is moved to one position by the presence of liquid attendant on flow and moves to another position upon cessation of flow with provisions including an expansible chamber for impelling the float to the other position either by delivering gas or air to the float chamber or by positively moving the float to the other position. The apparatus is particularly suitable for use in closed systems utilizing supply containers which are collapsed as the liquid is withdrawn.

International Classification:
F04B 4502 F04B 4906 F16J 110
US Classification:
417473
Abstract:
A reciprocating adjustable stroke positive displacement fluid pump is provided with an expandable chamber driven in the displacement or feed direction by an eccentric drive acting through a driven member. The eccentric drive moves the expandable chamber to its limit of excursion in the displacement or feed direction. Adjustment means cooperating with stop means limits the excursion of the driven member and the expansion of the expandable chamber in the suction or intake direction so that the amount of fluid pumped is continuously adjustable from no volume to the capacity of the expandable chamber by positioning the stop means. The pump is further provided with means for driving a plurality of individually adjustable pumps from the same drive motor and with means for equalizing the load on the pump motor.
