Title: Highly hydrogenated functional-terminated conjugated diene polymers
Inventor: ABRAHAM TONSON
IPC: C08F8/04
Filed: 1992-06-05
Abstract: Poisoning or deactivation of conventional homogeneous catalysts to be used in hydrogenation of the backbone unsaturation in liquid monofunctional and difunctional-terminated conjugated diene polymers, is prevented by reacting a blocking agent compound with the functional end groups present in these polymers. More specifically, subsequent to formation of a selected starting material monofunctional or difunctional-terminated conjugated diene polymer, a suitable blocking agent is reacted with the functional end groups of the polymer enabling relatively inexpensive titanium, iron, cobalt, or nickel-based homogeneous catalysts to be used in hydrogenating the backbone unsaturation of the polymer to a high degree. Subsequent to hydrogenation, the polymer is subjected to conventional hydrolysis using a mineral acid or base to remove the blocking groups and return the hydrogenated conjugated diene polymer to its original functionality.

Title: Flexible data size fast fourier transform process for sparse frequency sinusoidal and harmonic signal analysis
Inventor: LU IAN D
IPC: G06F17/14
Filed: 1994-02-22
Abstract: Conventional digital measurement instruments and software use radix-2 fast Fourier transform (FFT) to analyze steady state sinusoidal and harmonic signals. Steady state sinusoidal and harmonic signals occurs commonly in rotating machine vibration, mechanical and electrical modal oscillation, and electric power system. Analogue anti-aliasing filters and digital time domain windows, such as Hanning and Gaussian windows, are applied to the signal to reduce the error resulted from the radix-2 FFT. The use of these windows can be eliminated if the data size contains exact number of integral multiples of the sinusoidal and harmonic signals. Radix-2 FFT forces the user to limit data size (number of data points) to power of 2 (for example ...., 256, 512, 1024, 2048, ...). It is impossible to match a limited number of data sizes to the aforementioned signals with readily available data-sampling rates (such as 1000, 2000, 5000, 10000, ... samples per second). The following disclosure describe that through multiple application of flexible data size mixed radix FFT can eliminate the use of the windows and produce more accurate results.

Title: Personnel protection system for electrical power connections
Inventor: MCDONALD THOMAS M
IPC: H02H5/12
Filed: 1992-09-01
Abstract: A personnel protection system for electrical connections is disclosed, which is of the type that differentially senses the cur-rent flow between the power lead (50) and the return lead (52) (or between two power loads) is provided with an unbalancing im-pedance (70) which makes the current difference between the two leads sufficiently high to trip the device (48) and cause the pow-er to be disconnected. A utilization device (64) is similarly provided with an imbalanced impedance (80). However, that imped-ance is calculated to counteract the current imbalance caused by the first impedance (70), so that when the cable is connected to the utilization device (64), the current balance between the two conductors (50, 52) is restored, and power connection is main-tained in the cable. Thus, the system does not provide continuous power unless predetermined conditions considered safe for sec-uring the power are fully satisfied.

IPC: E05B65/10
Filed: 1994-06-01
Abstract: ABSTRACT OF THE DISCLOSURE     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.  The fire fuse assembly is configured to melt at temperatures substantially above normal room temperature to prevent engagement between the fire fuse assembly and the deadlock arm assembly, effectively preventing movement of the deadlock arm assembly out of its first position blocking movement of the linkage assembly in response to movement of the rod.

Title: Mounting system for fifth wheels
Inventor: KAIM JOHN W
IPC: B62D53/08
Filed: 1994-07-25
Abstract: Truck tractors are connected to their trailers by fifth wheels and several companies manufacture fifth wheel assemblies. The tractors consist of a pair of longitudinally extending beams or rails to which the fifth wheel assemblies mount. Each fifth wheel manufacturer provides several types of fifth wheels, depending upon the type of trucking service being provided. Complicating the situation is the fact that the lateral spacing between the beams will differ. As a result of these variations, different types of mounting brackets have been developed to secure the fifth wheels to the trailer frames. The drop-over bracket fifth wheel mounting assembly consists of an L-shaped angle brace which complements and is slipped over the beam of the tractor; a bracket on its top connects to the fifth wheel. The flat plate method utilizes a thick, flat plate to span across and rest upon each of the beams; it also has a top side bracket. The drop-over method resists longitudinal loads very well but has been found to develop fatigue cracks as a result of lateral and lateral overturn loads. The flat plate method has proved to be a more costly, yet more effective method of preventing fatigue cracking. The present invention combines the positive features of each individual system into a single, and unitary lightweight cast mounting assembly, thereby providing structural homogeneousity which is resistant to fatigue cracking. Since the combined bracket mounts directly to the tractor beams, it can be used from tractor to tractor if necessary, with no concern for the lateral spacing between the beams of a particular tractor.

Abstract: Hollow plastic blow-molded containers having a tubular bodies and integral improved, self-supporting bases. The bases have distinctly shaped supported feet disposed on legs at or near the periphery of the container bottom. The container legs extend outwardly and downwardly from the central region of the container on the inner side of the container bottom and extend downwardly from the container sidewalls on the outer side and are separated by ribs which coverage in a central region at the base of the container. At the terminal end of each of the container legs, there are horizontal contact surfaces or feet which are defined by foot edges which include an inner foot edge portion and an outer foot edge portion, the outer foot edge portion includes a pair of outer far corner foot edges and a far middle foot edge portion. The far middle foot edge portion extends radially to a point further than the outer far corner foot edges. The differences between the middle and far outer corner foot edge radii give rise to a container footprint which is essentially non-uniform with the circumference of the container. The unique, non-uniform footprint provides manufacturing advantages in terms of an expanded processing window which is well-suited to a high speed manufacturing environment.
