Title: Metal sheet prelubrication transfer system
Inventor: CAUDILL FORRESTER
IPC: B05D1/28
Filed: 1989-12-12
Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus and method for coating a surface of a moving metal sheet with a thin film of lubricant having a uniform thickness. The apparatus includes a lubricant applicator roller having an absorbent and tear resistant surface for engaging the metal sheet, a backup roller for engaging the applicator roller, a header assembly including nozzles evenly spaced across the passline of the metal sheet for delivering lubricant into the nip formed between the applicator roller and backup roller, and means for controlling and providing intermittent flow of lubricant through the nozzles. The method includes vertically displacing the applicator roller until it contacts the moving metal sheet and cyclically flowing lubricant through the nozzles for periods of time such that the amount of lubricant delivered into the nip formed between the applicator roller and backup roller approximates the amount of lubricant transferred by the applicator roller to the surface of the metal sheet during each cycle,

Title: Fitting for interconnecting non-metallic conduit
Inventor: HEATH KENNETH A
IPC: H02G3/14
Filed: 1990-01-22
Abstract: FITTING FOR INTERCONNECTING NON-METALLIC CONDUIT     Abstract of the Disclosure A wiring housing includes a main portion forming a box and a cover for the box.  The main portion has a side wall and a back wall and tubular projections extending from the side and back walls to form conduits sockets to receive the ends of rigid or flexible PVC conduit.  The cover has latches and the box has latch sockets to form a three-point snap connection between the components.  Openings into the box from the tubular projections form stop shoulders to limit the insertion depth of the conduit.  An open side of the box has outwardly sloping textured wall surfaces and the cover has a U-shaped channel fitting over the surfaces which, in assembly, form a water-excluding closure assembly.          The housing assembly is particularly effective for wire interconnections at the junctions of conduit runs.
Patent CA-2009330-A1 (CA)
IPC: D21F9/02
Filed: 1990-02-05
Abstract: A paper forming apparatus has a lower looped forming wire disposed for a portion of its travel over a curved apron board.  The paths of forming wire travel upstream and downstream of the apron board diverge.  Such divergence allows a secondary headbox to be brought into such a juxtaposition with the forming wire coming off the apron board as to permit the stock stream to impinge the forming wire both at a low angle and at a short distance to enhance formation of an additional web ply over  a previously formed web ply. In one embodiment, an upper looped forming wire is brought into co-running engagement with the lower forming wire over the downwardly extending downstream path of travel.  In two-wire embodiments, the turning roll for the upstream end of the upper forming wire is downstream of both the headbox slice and apron board to permit the headbox slice to be positioned close to the lower forming wire and allow the stock stream to be projected downwardly to impinge the lower forming wire at a small angle or a short distance from the slice, or both.

Each of the units includes a block carry-in generator, an adding section, a block carry-out generator and a carry coincidence checker.  The block carry-in generator is arranged to receive a plurality of carry generate variables and a plurality of carry propagate variables from the other units, generating a carry-in using carry look-ahead scheme.  The adding section is coupled to receive the carry-in from said block carry-in generator and further receives two operand data to be added and generates a resultant sum of the two operand data.  The block carry-out generator receives the two operand data and also receives the carry-in from the block carry-in generator.  The block carry-out generator produces a carry-out of the unit to be applied to a lower order block carry look-ahead unit. The carry coincidence checker is arranged to receive the carry-in from the carry-in generator and also receives a carry from another block carry look-ahead unit.  The carry, which is applied from another unit, corresponds to the carry-out.  The checker performs a coincidence check between the carry-in and the carry applied from another unit.

Title: Retaining wall and building block therefor
Inventor: MCKINNEY GARY S
IPC: E04C1/00
Filed: 1990-06-22
Abstract: RETAINING WALL AND BUILDING BLOCK THEREFOR            ABSTRACT OF THE DISCLOSURE           An  elongated  building block  has  spaced  apart inner and  outer  faces  and  top  and  bottom  faces  and complementary  end  portions  with  openings  therein.  The openings  of  the  block  are  disposed  on  a  straight longitudinal axis, and clearance is located adjacent the longitudinal axis and a central portion of the inner face of the block. When horizontal rows of similar blocks are stacked one upon the other, end portions of the blocks in one row are positioned above central portions of blocks in an adjacent row,  so the  joints between the blocks  are staggered.   Generally  vertical  connecting  rods   pass through aligned openings to connect alternate rows of the blocks together.  Clearance in alternate rows  of  blocks exposes  intermediate  portions  of  the  connecting  rods. When  used  as  an  embankment  retaining  wall,  generally horizontal  tie  back  rods  embedded  in  the  embankment connect  with the  exposed  intermediate portions  of  the connecting rods passing between alternate rows of blocks. Exposed  intermediate  portions  of  the  connecting  rods provide a relatively wide tolerance for connection to the tie back rods.            B182:440:29

Abstract: A C-MOS sense amplifier detects voltage differences between the signals applied to its inputs in correspondence with transitions of a clock signal.  It comprises a level converter, a sense circuit and a feedback circuit, which are inactive in a first inactive phase of the clock signal, while in a second active phase,  immediately following a clock signal transition, the sense amplifier reaches an operating point necessary to activate the level converter and the sense circuit, and hence a high positive feedback is set up which switches the sense circuit.   Finally, following the corresponding level transition of a delayed clock signal, the feedback signal generated by the feedback block reduces the dissipation of the entire differential sense amplifier to zero.
