Title: Freeze protective shipping units
Inventor: SCHEA HENRY E III
IPC: B65D81/18
Filed: 1992-01-13
Granted: 1996-03-12
Abstract: Disclosed are shipping and/or storage units (10) for containers (11) of liquid compositions, such as solutions of biological-ly active proteins, which are susceptible to physicochemical change upon freezing. Preferred container holders have double side-walls (12, 13) and a freeze indicator (16) adjacent a container-accommodating cavity (14). A phase change material (22) such as a carboxymethylcellulose gel is disposed in the enclosed space between sidewalls (18) and freezes at a temperature higher than the nucleation temperature of the composition. A freeze indicator (16) provides an irreversible visual signal upon reaching a tempera-ture intermediate the nucleation temperature of the liquid composition and the freezing temperature of the phase change material (22).

Title: Double lens helmet face shield with electric heating field
Inventor: REUBER DOUGLAS ALVIN
IPC: A42B3/22
Filed: 1993-03-02
Granted: 1996-03-05
Abstract: Known protective helmets used for motorcycle riding, flying and snowmobiling employ transparent visors that have heating elements to reduce and attempt to eliminate the build-up of ice, condensation and fog.  A double-lensed face shield is provided with a pair of electrodes formed on an inner face lens, in the air pocket formed between the inner face lens and the outer weather lens.  Substantially across one entire surface of the inner face lens is formed an electroconductive film.  An upper electrode extends from a first end along an upper margin of the inner face lens on the film to a second end.  On the opposite lower margin extends on the film a lower electrode from a first end to a second end.  An insulated contact passes from one side of the inner lens to the other and connects the first end of the lower electrode with a conductor which extends on the opposite side of the inner lens towards the  first end of the upper electrode.  Power supplied across the first end of the upper electrode and the tail end of the conductor will result in electrical flow across the film inhibiting fog, ice and frost.          Also provided is an assembly to permit the installation of face shields on helmets of different sizes and with openings of different configurations.

Abstract: A drive axle assembly and subassembly for use in tandem driving axle arrangements has a removable drive pinion shaft subassembly. An input shaft (14) is journalled in an axle housing (12) and is coupled to an output shaft (18) also journalled in the housing by an inter-axle differential (24) for torque sharing of driveline power. An input gear (28) receives power from the inter-axle differential and drives a countershaft gear (32) mounted on the drive pinion shaft (30). The drive pinion shaft is journalled in primary (44) and secondary (50) bearings which straddle the countershaft gear and are mounted on a removable cage (48) which substantially surrounds the countershaft gear. The drive pinion shaft with countershaft gear is assembled into the primary and secondary bearings on the cage and is shimmed (62, 64) between the bearings to form a pinion shaft and subassembly. A threaded nut (60) is torqued over the end of the drive primary shaft to retain and preload the drive pinion shaft in the bearings. The cage has a peripheral mounting flange (54) which permits the subassembly to be shimmed and bolted against the axle housing to locate the drive pinion on the axle ring gear. Upon installation of the subassembly into the axlehousing, a drive pinion pilot shaft portion (36) is journalled in a third bearing (38) in the axle housing.

Abstract: A radio communication unit for a digital communication system is provided in which an input information signal is protected from transmission errors by forward error correction encoding the information signal. In addition, the communication unit enhances subsequent processing of a transmitted form of the information signal by a hard-limiting receiver by inserting a predetermined synchronization sequence into the information signal. Further, a corresponding radio communication unit is provided which includes a hard limiting mechanism for removing the magnitude of each sample in a group of data samples of a signal received from over a radio communication channel. In addition, weighting coefficients of the hard-limited group of data samples for maximum likelihood decoding and diversity combining are generated by comparing the hard-limited group of data samples to a known predetermined synchronization sequence. Finally, estimated information samples are generated, utilizing the weighting coefficients, by maximum-likelihood decoding the group of data samples.

Abstract: A fastener comprised of six main components: 1) molding; 2) a molding clip; 3) a ring receptacle; 4) a retainer ring; 5) a circular shaped male snap; 6) a nail or screw to attach the male snap component to a flat mounting surface. The combination of which securely fastens molding to flat surfaces. The molding, which has a flat bottomed dovetail groove that runs the entire length on the back face of the molding, accepts the molding clip, ring receptacle and retainer ring. The molding clip assembly is held firmly in the molding groove by inserting the ring receptacle into the molding clip and thereby forcing the outward facing arms at the bottom of the clip into the inside walls of the molding groove. The molding clip, ring receptacle and retainer ring when used in combination with the molding groove, can then be forced over the male snap which in turn is fastened securely to a flat mounting surface. The resultant is molding being fastened securely to a flat mounting surface and which makes the molding completely removable and replaceable.

Abstract: A dual flush system for a toilet tank, to choose a desired flush volume of water from said tank to flush solids or liquids, depending on the operation of a two-position flush lever, comprising: a latching plate coupled to the overflow tube, having a latching aperture and a tilting gate connected to the flush lever mechanism; a secondary buoyant float slide retained by the overflow tube, having a latch member coupled thereto and connected to the flush lever, passing through the aperture of the latching plate; and a shoe rod coupled to said secondary buoyant float to push the stopper when it is discharging a first volume of water to flush liquids from the toilet bowl. For flushing solids, the flush lever is operated to a first intermediate position, lifting only the stopper causing a total flush of water because the latch member is latched by the tilting gate of the latch plate and the buoyant float as well as the shoe rod remain inoperative. When flushing liquids, the flush lever is operated to a second position lifting the tilting gate releasing the latch member allowing the secondary buoyant float to fall down together with the shoe rod to push the stopper impeding a total discharge of water.
