Patent CA-2080240-A1 (CA)
Inventor: GOSSMAN WILLIAM E
IPC: F16F13/26
Filed: 1991-04-09
Abstract: An active-controlled vibrating mount (142) permits static forces from a machine (23) to support while decoupling the trans-mission of dynamic vibrational forces. The mount provides a reduction of force losses from a first generating area (152) to a sec-ond force applying area (130,132) to actively control vibrations of a vibrating element (23). These force losses are minimized due to minimization of the mass and velocity of fluid pumped by pumping the fluid through the short large cross-sectional area pas-sageways (144, 146). The device provides for proper channeling of the forces to the vibrating element (23) in a uniaxial direction (x) and constrains the application of forces in non-working directions.
Patent CA-2080487-A1 (CA)
Inventor: NEVEU JEAN-LOUIS
IPC: D06B1/06
Filed: 1991-04-10
Abstract: In a process for impregnating a fibrous, woven, knitted or nonwoven fabric with an aqueous liquid, in particular of the type containing a treatment agent, the textile fabric (6) is placed on an endless cloth (4) permeable to liquids, the liquid is poured under gravity onto the textile fabric in the form of a liquid curtain or sheet transverse to the direction of motion of the latter, and a vacuum slit (13) arranged below the cloth produces a vacuum sufficient for at least part of said liquid to pass through the textile fabric. The rate at which the liquid is poured, defined with respect to the weight of the fabric passing below said liquid sheet, is greater than a given value above which the impregnation rate is a function of said depression and independent of the poured quantity, thus permitting uniform impregnation and easy control of the impregnation rate.

Title: Non-contacting mechanical face seal of the gap-type
Inventor: IDE RUSSELL D
IPC: F16J15/40
Filed: 1992-10-27
Abstract: ABSTRACT A rotary mechanical face seal for preventing leakage of a fluid,  either  liquid  or  gas,  across  two  relatively rotating surfaces.   The seal is of the non-contacting mechanical type  in which a  predetermined spacing  is maintained  between  the  relatively  rotatable  sealing washers by formation of a pressurized fluid film between the relatively rotating surfaces.  The opposed faces are constructed to provide a separation of the faces at start-up and thereby prevent damage or destruction to the faces before design pressures are achieved.  This is achieved by providing at least one of the opposed faces with a deflection bearing portion which causes the necessary deflections under load.  The bearing portion comprise a spaced series of lift pad sections.  A variety of lift pad constructions can be used.   The seal also includes a hydrodynamic radial bearing which centers the shaft in the static state to avoid shaft runout.

Title: High frequency multichannel diversity differential phase shift (dpsk) communications system
Inventor: WILKINSON ROBERT
IPC: H04B7/12
Filed: 1991-04-30
Abstract: A high frequency transmitter comprises a large number of narrowband channels spaced over a broad bandwidth transmission. In one arrangement input data to be transmitted is demultiplexed (1101) so that sections of data are transmitted in groups of channels at 50 baud (say), each 50 baud channel produces a number of diversity channels modulated using difference phase shift key (DPSK) (103) and then added (105) for transmission. In the receiver, coherent summation (803) of close-bunched channels can be used and semi-coherent channel addition (805) can be used across the complete bandwidth. The received signal is converted to digital form then processed by an FFT circuit to produce frequency bins corresponding to the transmitted diversity channel frequencies. DPSK  demodulation is carried out and running averages are carried out in each channel to determine the proportion of times that the phase difference falls within allowed limits (907). A discrimination level (908) determines whether individual channels should be excised (914) because of noise corruption. The remaining channels in groups are then added together to determine each data bit received. In semi-coherent addition (905), the measured phase vectors are added vectorially and the vector sum is used to determine the data bit.  In a second arrangement the channels of any one group are arranged in bunches of about 10 spread over a bandwidth of about 2 kHz (the experimentally determined coherence bandwidth) with the bunches spread over the whole transmission bandwidth. The bunch channels are added coherently and the resultants are added semi-coherently as before to determine the group data. The group data is then multiplexed to reproduce the high data rate input data. The arrangement allows high data rates to be transmitted with each of the diversity channels carrying only 50 baud.

Filed: 1993-03-03
Abstract: ABSTRACT         A process for the preparation of composition board, particleboard, fiberboard, waferboard and oriented strandboard as well as new and useful products thereof are provided for by the separation of one portion of the solid constituents of the composition  board and the separate blending of that portion with adhesive before combining and mixing that portion with the remaining solid constituents of the composition board product.          The method and product is particularly adapted to the use of fines as the one portion of the solid component of composition board and utilizing the precoated fines as an adhesive carrier in the final step of mixing or blending of the fines with the remaining composition board components.  The novel process and resulting products contemplate the separation of the solid components of the composition board products by particle size so that particles of 10 to 20 mesh, 20 to 40 mesh and 40 mesh and smaller are first separated from the remaining components and then the smallest component is judiciously coated with an adhesive to function as an adhesive carrier when mixed with the remaining solid components of composition board.  The novel products of the invention include fines as adhesive nuclei for binding the larger components of the composition board together and produce a more uniform, cohesive and novel composition board product.

Abstract: A method for rotating bi-level image data plus or minus 90°. An 8 x 8 pixel block is selected for rotation from the image data and, using lookup tables, an intermediate matrix is generated dynamically and  stored  into  two  32-bit  registers  in  the processor.  Generation of the intermediate matrix partially rotates and stores the odd-numbered rows from the block of data in the first 32-bit register and the even-numbered rows from the block in the second 32-bit register. The first and second registers are copied,  respectively,  into third and fourth 32-bit registers. The first and second registers are then  shifted  one  bit  in  opposite  directions.  The  first register is logical ORed with the fourth register, and the second register is logical ORed with the third register so that the even bits are replaced in one register and the odd bits in the other. These steps are repeated for all remaining blocks of image data.
