Brendan Walsh - Bronx NY 10470

International Classification:

A47C 1700

US Classification:

5 21, 5 91, 5308

Abstract:

A space-conscious, functional design for a loft bed. The design serves to optimize space by incorporating multi-functional features, such as drawers, closet space, or cabinet space, within the assembly for the bed itself. Specifically, a plurality of steps are substantially parallel to the length of the bed, and lead upwardly toward the foot of the bed for easy access to same. Such steps incorporate the aforementioned storage space, with access to the drawers or closets from a side position. As such, the unique assembly allows for a desk, computer work station, bar, or additional wide storage space below the bed and behind the steps, adding to the overall versatility of the assembly. Finally, in the preferred mode the unit is modular in nature and may be assembled and rearranged based upon user preference.

Appl. No.:

11/569365

Inventors:

Brendan M. Walsh - Simsbury CT, US
P. Cary Franklin - Madisonville KY, US

Assignee:

Ensign-Bickford Aerospace & Defense Company - Simsbury CT

International Classification:

C06C 5/04

US Classification:

1022758, 1022025, 1022755

Abstract:

This invention relates to a detonating cord () having a core () of reactive material and a composite jacket around the core, and the method of its manufacture. The composite jacket includes an interior jacket () in contact with the core and a sacrificial jacket () disposed over the interior jacket. The sacrificial jacket prevents the cord from being cut off by the detonation of another detonating cord of like core load disposed adjacent thereto. The sacrificial jacket is separable from the interior jacket beneath it under the force of the adjacent detonating cord, thus absorbing energy and allowing the first detonating cord to remain intact. The detonating cord may have a core load of not more than 3. 2 grams/meter (15 grains/ft) or, optionally, less than 1. 25 g/m (6 grains/ft).

Inventors:

Brendan Walsh - Hoboken NJ, US

International Classification:

A43B 5/00

US Classification:

36134, 12142 P

Abstract:

An apparatus including a retaining device and a plurality of flexible memory spike devices for golf. The retaining device may be adapted to be temporarily attached to a shoe. The retaining device may be adapted so that the plurality of spike devices can be attached or detached from the retaining device. The retaining device may be made of an elastomeric material. The retaining device may have a plurality of openings, and each of the plurality of spike devices can be at least partially inserted into a corresponding one of the plurality of openings to attach each of the plurality of spike devices to the retaining device.

Abstract:

A shock-resistant electronic circuit assembly (10) is provided in which an electronic circuit is encased in an encapsulation (14) that engages a surrounding enclosure (18, 22) in shock-dispersing contact therewith. The encapsulation may have a plurality of edges (16, 16a, 16b), fins (24) or bosses (70) that bear against the enclosure. The encapsulation may include a shock-absorbing material (14f) disposed against the enclosure to protect the circuit against vibrations and a structural support material (14e) to protect the circuit against stress. The circuit assembly (10) may contain a capacitor (34) for storing an electrical signal and timing circuitry for releasing the stored energy after a predetermined delay. The circuit assembly (10) may be part of a transducer-circuit assembly (55) that includes a transducer module (58) for converting shock wave energy into electrical energy for the electronic circuit, and the released energy may be converted into a detonation initiation signal. Assembly (55) may be part of a detonator (100) that receives a non-electric initiation signal and detonates following the delay determined by the electronic circuit.
