Filed:

May 13, 2009

Appl. No.:

12/465185

Inventors:

Hugh Q. Cook - Foothill Ranch CA, US

Assignee:

Bal Seal Engineering, Inc. - Foothill Ranch CA

International Classification:

F16J 15/34
F16J 15/32

US Classification:

277353, 277551

Abstract:

Seal assemblies are herein discussed. The seal assemblies can have a stiff backing ring supporting a seal ring, which is positioned adjacent an inner seal ring. In preferred embodiments, the inner seal ring is made from a material that enables the inner seal ring to absorb media particles in situ to change its particle density. This allows the seal assembly to form wearable surfaces on the fly to decrease wear on the seal ring.

International Classification:

H01R 24/04

US Classification:

439669

Abstract:

Connector assemblies for use to concurrently transmit multiple signals or sources. The connector assemblies are generally formed by coupling a plurality of ring contacts, sealing rings, and spring contact elements together with at least one holding ring to form a connector having a common bore for receiving a lead cable. Contact grooves or spring chambers for positioning the spring contact elements are formed in part by assembling multiple components together. The connector assemblies may be used in a number of industries and applications.

US Classification:

29876, 29428, 29874, 29877, 29884

Abstract:

Connector assemblies for use with implantable medical devices having easy to assemble contacts are disclosed. The connector assemblies are generally formed by coupling a plurality of ring contacts, sealing rings, and spring contact elements together with at least one holding ring to form a connector having a common bore for receiving a medical lead cable. Contact grooves or spring chambers for positioning the spring contact elements are formed in part by assembling multiple components together. A further aspect is a provision for encasing each connector assembly or stack inside a thermoset layer or a thermoplastic layer before over-molding the same to a sealed housing.

Assignee:

Bal Seal Engineering, Inc. - Foothill Ranch CA

International Classification:

H01R 4/48

US Classification:

439817

Abstract:

A connector includes a canted coil spring, a multi-piece housing, and an insert element. The multi-piece housing includes a first housing part defining a bore of the housing, and a second housing part connected to the first housing part and comprising a tapered wall defined by a first section of the second housing part with a first inner diameter and a second section of the second housing part with a second inner diameter greater than the first inner diameter. A groove is formed in the bore by the connection of the first housing part with the second housing part, the groove having at least a portion of the canted coil spring disposed therein and having a tapered side wall formed at least partly by the tapered wall of the second housing part. The insert element is insertable into the bore to engage the canted coil spring for connection with the housing.

Inventors:

Derek Changsrivong - Foothill Ranch CA, US
Hugh Cook - Foothill Ranch CA, US

Assignee:

BAL SEAL ENGINEERING, INC. - Foothill Ranch CA

International Classification:

F16B 7/00
B23P 11/00

US Classification:

403328, 29428

Abstract:

A progressive release or multi-point engagement device according to aspect of the present disclosure includes a first component and a second component connected to the first component with mounted coil spring. The first component is movable relative to the second component and latch by moving the canted coil spring to a second common groove. Alternatively, a second spring is used to move the second component and relative to a third component. When a second engagement position is desired, a relatively higher a force may be necessary to move the relevant component.

Assignee:

BAL SEAL ENGINEERING, INC. - Foothill Ranch CA

International Classification:

F16B 39/282

US Classification:

411145

Abstract:

Fastening devices are disclosed herein with variations on how said devices resist loosening or un-fastening from a structure or structures. In some examples, the fastening devices accomplish the removal resistant condition by using a spring component engaging ridged surfaces. The spring component generally consists of a spring ring conveniently coiled to a canting position. One exemplary design is characterized by incorporating a screw element with its head underside surface being ridged and a lock element with a ridged topside surface and engaging the two ridges surfaces. Another exemplary design is characterized by a screw element having a head outer sidewall being ridged for cooperating with a bore having a ridged inner sidewall. The bore can be part of a first body or structure or a lock element.

International Classification:

F16B 17/00

US Classification:

403361, 2952501

Abstract:

Dual directional latch devices or connectors are described wherein a first connector component and a second connector component have a first latched position and a second latched position when moving in a first direction and wherein movement in a second direction is also possible when a restriction feature is overcome. As described, opposing magnetic forces, pneumatic pressure, spring force, and a crushable force may be incorporated so that further movement in the second direction must overcome the restriction feature. The dual direction latch devices may be used with articles of manufacture such as with implantable medical devices, door panels, airplane panels, and drilling devices to name a few.
