Title: Method and apparatus for producing a surface covering having reduced surface gloss and surface covering produced thereby
IPC: C08F2/46
Filed: 1981-03-09
Abstract: This invention pertains to a method and apparatus for producing a cured resinous coating which exhibits a reduced gloss level. In a preferred embodiment, the cured resinous coating which exhibits a reduced gloss level is a wear resistant coating and is superimposed on a resilient floor covering material. The gloss level is reduced by subjecting the coating to corona discharge before it is cured. The curing process is achieved at least partially by irradiation of the coating and may additionally involve some moisture-curing.

Title: Adapter for connecting flexible pipes
Inventor: BRUSADIN GIACOMO
IPC: F16L25/14
Filed: 1983-01-13
Abstract: An adapter for connecting flexible pipes of widely varying diameters consists of a main cylindrical body (1), having an externally tapered pipe- holder shank (3), to which there can be fitted flexible pipes having widely different diameters, these being fixed to it by respective resilient rings (8-9) which can be clamped by means of a clamping ring (4) screwed on to the said main body. When the adapter comprises both of the resilient rings (8-9), screwing of the said clamping ring (4) will cause the outer resilient ring (9) to clamp a first dimensional range of pipes to a first part of the pipe-holder shank (3); removing the said ring (9) makes it possible to fit another, dimensionally larger range of flexible pipes to the adapter, which may then be clamped by the next resilient ring (8) and the clamping ring (4). <IMAGE>
Patent GB-2115998-A (GB)
Title: Apparatus and method for rapid analog-to-digital conversion
Inventor: SAUER DONALD JON
IPC: H03M1/00
Filed: 1983-02-28
Abstract: An analog-to-digital converter develops an N-bit digital word over a period of N cycles of a sampling clock signal. As the sampled analog signal is clocked through a tapped analog delay line (112) and is recovered at N separate output taps (T1, T2, T3, T4) at successive delay times later, successive comparisons (C1, C2, C4, C8) each produce one digital bit, beginning with the most significant bit, during each clock signal cycle. The digital bits developed progress through shift registers (SR2, SR4, SR8) having numbers of stages selected so that an N-bit parallel digital word is produced at the shift register outputs when all N bits have been determined. A new digital sample is produced for each clock cycle. <IMAGE>

Abstract: Relates to sheet counting apparatus of the kind employing a number of hollow spindles (2) arranged in a circle on and extending vertically from a horizontal rotatable base (4), suction being applied to each spindle during each rotation of the base as the spindle passes a stack (10) of sheets to be counted, one end of the stack being held (12, 14) and each spindle head having an apertured suction face (6) which is presented to the free end of the stack so that the free end of each sheet in turn is deflected to a new position as the base rotates. The spindle is formed with a head 36 detachable from the body 30, the spindle head including the apertured suction face and being fastened to the body by a bayonet connection 38, 40 or other fastening means defining the relative angular position of the head and body. This permits easy access to a filter 42 provided within the body below the suction face and easy replacement when a suction face shows wear or to facilitate counting of different kinds of sheets. The filter is provided with lifting ring 46 for easy withdrawal, the ring 46 lying within the retaining spring 44. <IMAGE>

Title: A security system
Inventor: BOSEN ROBERT J
IPC: G07C9/00
Filed: 1983-04-22
Abstract: A security system for controlling access to property generates a first variable which is displayed to the user desiring access. The user has a separate calculator device into which this first variable is entered and which then generates a second variable having a predetermined relationship to the first variable (or the user could derive the second from the first using a look-up table). This second variable is then entered by the user into the security system which has itself also generated a second variable. The system compares the second variables and if they correspond, lock means are actuated and access is granted, e.g. through a door or to a computer programme or to data stored in a computer or to permit storage of an edited document in word-processing. <IMAGE>

Title: Arm wrestling device
Inventor: CHRISTENSEN JULIE CAROL
IPC: A63B26/00
Filed: 1985-01-17
Abstract: The device enables one or two players to play a game resembling conventional arm wrestling. Each player has a seat 8 and a handle 16 to grasp, the handle being mounted on an associated operating arm 15 connected to a common rotatable main shaft (24) with biasing means (19, 20) being provided to compensate for differences in the players' strengths or physiques.

The biasing means may comprise a reversible motor (19) which drives, through reduction gearing, the input of a slipping clutch (20), the output of the clutch being connected to the main shaft. The strength of the coupling effected by the clutch can be varied. Sensing switches (30, 35) are operated by each player when he or she is in a suitable playing position and any movement from that position generates warning signals. When used by a single player, the biasing means counters unaided the forces exerted by the player and the second handle and arm may be omitted if the device is always to be used by only a lone player. <IMAGE>
