Title: Tamper-evident buttress plug closure
Inventor: MAGLEY ROBERT E
IPC: B65D55/02
Filed: 1988-08-31
Granted: 1992-07-14
Abstract: Abstract of the Disclosure A tamper-evident buttress plug for sealing closed a plastic 55-gallon drum includes a plug body which is externally threaded and compatible with the internally threaded container outlet, a ratchet ring which includes a circumferentially distributed series of ratchet teeth on its inner surface and a series of four frangible elements which initially integrally join the ratchet ring to the plug body.  The container outlet has neck which is configured with two spaced series of ratchet teeth which are of a size and configuration so as to be mutually engageable with the ratchet teeth on the closure ring.  As the closure is threadedly advanced into the outlet, threaded engagement is first achieved and then ratchet engagement.  When it is time for the closure to be removed from the container, the frangible elements must be severed so as to separate the ring and the plug body.  In view of the fact that the 55-gallon plastic drum is blow-molded by split-block technique, it is necessary for the two series of ratchet teeth on the container outlet to be less than 180° in their circumferential extent thus leaving spaces between the series.  In order to prevent compression of the ring by squeezing inwardly at the location of these two spaces, semi-circular raised protuberances are provided in order to prevent ovalizing and an ability to disengage the ratchet teeth.

Granted: 1995-08-08
Abstract: A process for producing a styrene-based polymer, particularly a styrene-based polymer having mainly a syndiotactic structure by polymerizing a styrene-based monomer in the presence of a filler by using a catalyst containing (A) a titanium compound and (B) aluminoxane as main components.          The filler acts as a catalyst carrier, increasing catalyst activity, and thus de-ashing treatment is not needed.  When the filler is used in a large amount, there is obtained a composition in which the filler is uniformly dispersed in the styrene-based polymer.  The styrene-based polymer or styrene-based polymer-containing composition is excellent in heat resistance and chemical resistance.

Title: Processor suitable for recursive computations
Inventor: KNOWLES SIMON C
IPC: H03H17/02
Filed: 1989-04-05
Granted: 1992-12-01
Abstract: ABSTRACT   A processor suitable for recursive computations incorporates multiplier cells (16) connected to form rows (12) and columns (14). Each row (12) is arranged to multiply by a coefficient. It begins with accumulator cells (18 and 20), and continues with multiplier cells (16) arranged to multiply by individual coefficient digits and disposed in descending order of digit significance. Columns (14) other than the first column (141 ) begin with a multiplier cell (16), and the higher significance columns (141 to 144) terminate at respective accumulator cells (20). Any intervening multiplier cells (16) are arranged in ascending order of multiplier digit significance. The multiplier and accumulator cells (16 to 20) operate in accordance with signed digit number representation arithmetic involving digit redundancy. They generate sum and transfer digits for output down columns (14) and along rows (12) respectively to neighbouring cells, in the direction of increasing digit significance in the case of transfer digits. The cell arithmetic employed makes it possible to compute results most significant digit first. Each result digit is recycled when formed to provide a multiplicand digit input for all multiplier cells (16) of a respective row (12) selected in accordance with result digit significance. The processor (10) is also arranged to add successive non-recursive input terms to multiplier products. This provides for the processor (10) to provide a first order infinite impulse response (IIR) filter section, and two cascaded processors (50,50') provide a second order IIR filter section.

Title: Method and apparatus for a parallel carry generation adder
Inventor: PRIEM CURTIS
IPC: G06F7/508
Filed: 1989-09-22
Granted: 1993-10-12
Abstract: ABSTRACT OF THE INVENTION           The parallel carry generator of the present invention calculates the carry for a m bit number within log2n + 1 gate delays where n is smallest binary ordered number greater than or equal to m. Thus in the parallel carry generation adder of the present invention, the sum is calculated in log2n + 2 gate delays. Thus, a 32 bit carry computation can be performed in as little as 6 gate delays. This is achieved by breaking down the 32 bit word according to binary ordered values and cascading portions of the calculations required wherein the carry generated for the most significant bit of the lower binary ordered group is used to calculate the carrys for the bits in next higher ordered group By ordering the bits and the logic circuitry in this manner, the amount of gate delays to perform the carry calculation is minimized without excessively increasing the amount of logic.
