42575419, Mar 24, 1981

Filed:

Sep 4, 1979

Appl. No.:

6/071885

Inventors:

David W. Souza - Fremont CA

Assignee:

S J Marketing, Inc. - Palo Alto CA

International Classification:

G01F 1124

US Classification:

222362

Abstract:

A device for dispensing a measured quantity of granular material from a container includes a cap adapted to be secured to the open end of the container, and a generally cup-like housing secured to the interior surface of the cap. A dispensing member is disposed within the housing, and is adapted to be rotated about the axis of the cap and housing by a lever which extends outwardly from the cap. The dispensing member includes a cylindrical chamber extending therethrough parallel to the axis thereof, and adapted to be rotated to register with an intake port in the housing to be filled with granular material. The dispensing member may be rotated to bring the chamber into registration with a discharge port extending through the cap.

David W. Souza - Fremont CA

International Classification:

G01F 1110

US Classification:

222168

Abstract:

A device for dispensing a selectively variable measured quantity of granular material from a container includes a cup-shaped first member and a hollow cylindrical dispensing member having a sidewall disposed concentrically within the first member. The dispensing member includes a handle, an open bottom, a closed top panel, and a pair of radially extending side panels depending from the top panel to define a measuring chamber. The volume of the measuring chamber may be varied by means of an adjustment member having a lateral panel disposed in a recess in the top of the dispensing member and a depending panel which forms a sidewall of the measuring chamber. The dispensing member is rotatable about a tubular projection extending from the first member, so that the measuring chamber may be moved from alignment with an intake port in the bottom panel of a reservoir supported above the first member to alignment with a discharge port in the bottom of the first member. A post having a plurality of radially extending rods extends through the first member and the dispensing member. In one embodiment, the post rotates with the dispensing member to stir the granular material.

Inventors:

David W. Souza - Fremont CA

Assignee:

SJ Marketing Incorporated - Palo Alto CA

International Classification:

G01F 1146

US Classification:

222438

Abstract:

A device for dispensing a selectively variable measured quantity of granular material from a container includes a cap adapted to be secured to the open end of the container, the cap including a generally cup-like coffer disposed in the neck of the container. A disk-like lid is rotatably secured to the cap in coaxial fashion, and includes a discharge port subtending a small angle therein. The cap includes a boss projecting radially inwardly in the coffer and disposed directly adjacent to an inlet port in the inner end wall of the coffer. An adjustment member is rotatably received in the coffer, and includes a radially extending wall parallel to the axis which is selectively variably spaced from the boss to define a chamber of variable volume communicating with the inlet port. A disk-like bottom cover includes an inlet opening therein, and is secured to the inner end of the cap and adapted for rotation in concert with the lid. With the container in the inverted position, granular material therein will fall gravitally through the opening in the bottom cover and the inlet port in the cap to fill the chamber in the coffer thereof to the extent permitted by the position of the wall of the adjustment member.

International Classification:

G05B 19401

US Classification:

36416701

Abstract:

A thermoplastic bag making machine having a sealing bar assembly driven by two separate linear drive units is initialized following full shutdown by traversing the linear drive units at constant velocity against mechanical stops, and then resetting position error signals and traversing the bar a known distance to a home position. This procedure is also useful for single linear drive units, as well as multiple linear drive units that must be coordinated for position and motion. In the case of multiple drive units, procedure for offsetting travel distances off the stop for non-uniformity in stop positions is utilized.

Inventors:

David W. Souza - Fremont CA

International Classification:

E05C 1918

US Classification:

292289

Abstract:

Multiple embodiments of a security lock for hinged entry doors or the like are disclosed, each having a strike plate adapted for mounting on the door jamb with a lock element being selectively operable for locking the door and being opened inwardly. In one embodiment, the lock element is engaged with a slotted extension of the strike plate for locking the door and with an offset plate portion for storing the lock element in an unlocked position out of engagement with the door. In another embodiment, the lock element is connected to an offset portion of the plate by an elongated flexible element such as a chain. In yet another embodiment, the lock element is an elongated hook member which is rotatably attached to the plate and extends inwardly of the door in its closed position, the hook member being rotatable into either a locking position for engaging the door after it is opened a short distance from the jamb or an unlocked position. In a further embodiment, the lock element is supported in an unlocked position upon a portion of the plate by a magnet. In a still further embodiment, the lock element is attached to a key for the door.
