Abstract: A latch assembly for a fire door having a pushpad for emergency exit is described. The pushpad is connected to a rod to transfer motion of the pushpad to the latch assembly. The latch assembly includes a platform attached to the fire door, a linkage assembly attached between the rod and a latch bolt, and a deadlock arm assembly attached to the platform. The deadlock arm assembly is movable between a first position to block movement of the linkage assembly and a second position to allow movement of the linkage assembly. A fire fuse assembly is also attached to the linkage assembly to move the deadlock arm assembly out of its first position blocking movement of the linkage assembly at normal room temperature.

Abstract: A mullion assembly mountable in a door frame includes a bottom fitting attached to a floor and a top fitting attached to the door frame above the bottom fitting. The top fitting supports a bolt engagement assembly for engaging a lock assembly positioned in a mullion cavity of a mullion. The lock assembly has a bolt extendable from the mullion cavity to engage the bolt engagement assembly supported by the top fitting and hold the mullion in a fixed position. Retraction of the bolt is controlled by a key lock assembly that allows controlled access disengagement of the bolt from the bolt engagement assembly, followed by pivoting movement of the mullion away from its upright position in the door frame.

Abstract: A reuseable electrical connector is disclosed for providing electrical and physical connection between electrical wires. An electrically conductive concave plate of generally triangular cross-section, having wire entry holes disposed along one side and generally opposing gripping edges disposed opposite to the holes is enclosed within an electrically insulating exterior portion.

Abstract: A reusable landing zone transportable as equipment in an emergency vehicle and rapidly deployable by persons on the ground is disclosed for marking an area where a helicopter may safely land on an suitable surface. A plurality of bar masses are removably disposed on top of and attached near the edges of a rectangular foldable sheet using spring-closed hooks. Similarly, a bag mass is removably disposed on top of and attached near each corner of the sheet. A foldable, highly visible and reflective target is attached to the upper surface of the sheet so that the center and size of the sheet may be easily seen.

Abstract: A portable grill is disclosed for cooking outdoors with charcoal, and cooking indoors on a stove or in an oven. A cooking rack is disposed within a bottom pan having a generally flattened bottom, and a top plan is removably placed over the bottom pan. The bottom pan may be support by placement on a foldable stand.

Abstract: An accessory is disclosed to be detachably secured to a golf bag for carrying supplemental golf related and personal items. A plurality of quick release closeable pockets are columnarly mounted upon the exterior face of a generally rectangular panel. Removable attachment is made to a standard golf bag through the use of tensioned, hooked fasteners at the top and bottom of the rectangular panel.

Abstract: A temperature alarm is disclosed for attachment around the exterior of the flue pipe of a wood-burning or similar stove, with alarm activation temperature selected by slidable adjustment along the flue pipe. A bimetal thermostat is mounted in close proximity to the flue pipe, and acts to close an electrical connection between thermally protected power supply and acoustic horn. A system test circuit is provided.

Abstract: An approaching vehicle informing system and method for informing the driver of a vehicle of the presence of a relatively approaching emergency vehicle and providing the driver with information regarding the amount of time until vehicles meet. Included are a transmitting station for simultaneously emitting periodic electromagnetic and sound pulses of preselected frequencies located on the emergency vehicle, and a receiving station located on the driver's vehicle. The receiving station includes circuitry to receive the electromagnetic and sound pulses and discriminate signals of the preselected frequencies. A microcomputer is programmed to measure the time interval between simultaneously emitted electromagnetic and sound pulses, determines the Doppler frequency shift of the received sound pulse, and calculates the time until vehicles meet, which is displayed in numerical form to the driver in the event the Doppler frequency of received sound pulses exceeds the frequency of emitted sound pulses.

Abstract: A mold holding apparatus is disclosed for securely holding plaster molds used in the production of ceramic, porcelain and plastic items permitting molds to be oriented so as to permit filling of pour holes present in molds, and to facilitate the uniform pouring off of excess slip. The apparatus includes adjustable retainers for removeable attachment of a mold to a rotatable platform, and center of mass adjustments and frictional contact surfaces for uniform rate of pouring off of excess slip.

Abstract: A coverlet is disclosed for wear by non-ambulatory patients during transportation in shower chairs and mobile commodes. Counterpart front panels are attached together, and counterpart back panels are attached to the front panels so as to provide head and arm openings and entry from the back. Dimensions of the front and back panels are chosen to accommodate patients of varying physiques and to prevent interference with moving parts of shower chairs and mobile commodes.

Abstract: An inertial valve apparatus is disclosed for automatically stopping the flow of liquids or gases in the event of an earthquake or similar vibration, and simultaneously causing the liquid or gas to be vented. The apparatus includes a spring loaded double-seated valve that is held in an unactuated position by a latch. A mass is adjustably suspended, according to the sensitivity to vibrations desired, along a trigger arm connected to the latch, so that movement of the mass in response to vibrations causes the latch to release, permitting the valve to move to an actuated position where the normal flow of liquid or gas is stopped and venting takes place.
