Patent GB-2280734-A (GB)
Title: Proximity fuze and method of fuzing
Inventor: MCILROY JAMES WILLIAM
IPC: F42C13/02
Filed: 1986-04-18
Abstract: A proximity fuze generates a focussed beam 18 of pulsed laser radiation. Reflected pulses are examined by a range gate 26 and by a comparator 36 which allows firing only if the pattern of reflected pulses matches one of a number of stored target profiles. The range gate 26 passes only those pulses from targets 19 within a required range bracket. An integrator 31 passes only pulses which are of long enough duration to be consistent with reflection from a desired target. <IMAGE>

Title: Control of exhaust in ported two-stroke engines
Inventor: SCHLUNKE CHRISTOPHER KIM
IPC: F02D43/00
Filed: 1986-05-23
Abstract: A valve 33 in the piston-controlled exhaust port 21 is controlled in response to at least engine speed and load to regulate the degree of throttling and the timing of exhaust discharge. An electronic control unit 60 receives inputs from sensors of air mass flow, engine speed and temperature, throttle valve position and the position of the valve 33 and provides outputs to the valve 33, a fuel injector unit 53 and an ignition controller 65. The valve provides increased retention of exhaust gas in the cylinder 14 and reduction of exhaust emissions. <IMAGE>

Title: Method for pulverizing gelatin, and the use in paints, coating layers, films, and finished cloths
Inventor: NISHIBORI SADAO
IPC: C09D7/65
Filed: 1989-01-27
Abstract: A method for pulverizing gelatin and to products in which pulverized gelatin is used is described, wherein the pulverisation of hydrophilic and water-soluble dry gelatin with relatively high jelly strength is effected in a medium of dimethylformamide or an organic solvent admixed with dimethylformamide in an atmosphere where moisture is eliminated. Paints containing synthetic resin solutions in dimethylformamide or the organic solvent admixed with dimethylformamide which contains gelatin particles of 30 microns or less are also described whereby paint layers, coating layers, films and finished cloths that are formed by using said paints and synthetic resin solutions are obtained.

Title: Jitter-invariant switched capacitor pulse shaper
Inventor: COLBECK ROGER
IPC: H03K5/01
Filed: 1989-05-17
Abstract: The present invention provides an output pulse signal from an input digital signal which can be fabricated in an integrated circuit, and produces an output signal which retains the desired pulse shape unaffected by jitter. In the present invention the pulse shape is formed by using a switched capacitor FIR filter to form the pulse shape (referred to herein as a pulse shaper), and then by controlling the clocking of the digital signals used to operate the pulse shaper to control the timing of different segments. The result is an output signal which has jitter but retains the desired pulse shape. Since a phase corrector which senses jitter can control the clocking, the output pulse shape is unaffected by jitter. The invention can be produced in an integrated circuit since switched capacitor pulse shapers are used, rather than a continuous time filter. An analog pulse signal is produced from an input digital signal by applying the input digital signal to serial shift registers, each spanning less than a baud, operating switched corresponding ones of the shift registers to form different parts of an output signal, summing the output signals in time to form a combined output signal, and low pass filtering the combined output signal to form the analog pulse signal. …<IMAGE>…

Title: Plastics filling in stator/casing gap in an electric motor
Inventor: CAP HEINRICH
IPC: H02K29/08
Filed: 1989-06-09
Abstract: A brushless electric drive motor, for example, for a disc storage drive, comprises mounting flange (8) which supports a stator (15) surrounded by a rotor (3, 21) fixed to the shaft (5) for rotation therewith. To reduce noise and vibration, a part or all of a gap (17) defined between the flange (8) and the stator (15) is filled with a plastics material in which a shielding ring (13) and a printed circuit board (14) may be embedded. By this means, the mounting flange (8) and stator (15) effectively form a one-piece unit. Axial and/or radial electromagnetic disturbing forces acting between the rotor and the stator are minimized by arranging that the sum of the axial forces between rotor and stator are preferably zero. <IMAGE>

Title: Self-plugging blind fastener
Inventor: DENHAM KEITH
IPC: F16B19/10
Filed: 1992-08-21
Abstract: A self-plugging blind fastener (10, 74, 90) suitable for fastening apertured sheets together, and of the type comprising a body (12, 78) having a shank (16), headed at one end, and an axial bore (20) in which is disposed an elongate stem (14, 76, 92) which, in use, is pulled to expand the shank (16) and lock part of the stem (14, 76, 92) in the body (12, 78), has improved means for locking the stem (14, 76, 92) in the body (12, 78). The head end of the bore (20) is of reduced diameter and presents a stop-shoulder (30). The stop-shoulder (30) is an annular skirt (34) partly separated from surrounding material by an annular cleavage (32), and presents a planar stop-face (31, 84) facing away from the head-end. The stem (14, 76, 92) comprises a plug (42) which is connected by a breakneck (46) to a stem-tail (40) for pulling the plug (42) into the bore (20) of the body (12, 78). The plug has an annular locking recess (50) spaced from the breakneck (46), and is radially enlarged on the side of the locking recess (50) remote from the breakneck (46) to provide a plug-shoulder (62) and shank-enlarging means (66, 68, 69). The plug-shoulder (62) presents a planar face (64, 94) for engaging the stop face (31, 84) of the body (12, 78) and deforming the annular skirt (34) into the locking recess (50) during setting of the fastener (10, 74, 90). The planar face (64) of the plug (42) and the planar stop-face (31) of the body (12) may both be at right angles to the axis of the bore (20), or either the planar face (94) or the stop-face (84) may be inclined at an angle not greater than 10 DEG  to a plane at right angles to the axis, thereby enabling deformation of the skirt (34) to begin at a lower force than would be required if the faces (64 and 84 or 31 and 94) were parallel. <IMAGE>
