Title: A.C. to D.C. converter
Inventor: SCHOOFS FRANCISCUS ADRIANUS CO
IPC: H02M7/217
Filed: 1989-05-22
Abstract: An a.c. to low voltage d.c. converter comprises a pair of input voltage supply lines (Vin, OV) and a semiconductor switch element (T1) and a capacitor (C1) connected in series between the supply lines. An output (Vo) for d.c. voltage is provided across the capacitor (C1). A sensing circuit (10) is responsive to the input voltage and is arranged to trigger the switching element (T1) to conduct only during a portion of the a.c. voltage below a predetermined voltage. Modified sensing circuits are described (Figs 2 to 4). The ac to dc converter may be formed as an integrated circuit (IC, Fig 5) and can be fed from an ac supply via a transformer (T) and a bridge rectifier (BR). <IMAGE>
Patent GB-2220065-A (GB)
Title: Coating inspection
Inventor: MILNE JAMES MORRIS
IPC: G01B11/06
Filed: 1989-05-26
Abstract: A method and an apparatus are provided for inspecting a coating (12) on a substrate (10) both to enable any disbonds to be located and to measure the thickness of the coating (12). The coated surface (13) is illuminated by a single brief pulse of radiation from a flash lamp (15) synchronlsed with the frames of an infra-red camera (20). The camera produces a TV- compatible signal which is recorded by a video recorder (22). Slow replay of the recording on a TV monitor (24) enables disbonds and thickness variations to be located, while averaging a stripped line of signal at a predetermined time interval after the pulse enables the thickness of that portion of the coating (12) to be determined. The relationship between surface temperature and coating thickness can be found by a calibration experiment. <IMAGE>

Title: Telescopic cylinders
Inventor: ATKINSON JOHN
IPC: B66C23/70
Filed: 1990-03-13
Abstract: A hydraulic or pneumatic telescopic cylinder incorporates a piston rod (6, 8) at each end of the main cylinder body (4). The piston rods (6, 8) are extendable from and retractable into the main body of the cylinder (4). Each piston is extendable Independently of the other. When both pistons are fully retracted, one con rod (6) telescopically encloses the second piston rod (8). Piston rod (8) may be locked in either a fully extended or a fully retracted position so as to permit the other piston rod (6) to be used In a conventional manner. Retraction of the con rod (8) is effected by supplying pressure fluid through a port (26) leading to a cavity (24), whereby a floating annular piston (22) acts against a stop (28) on the rod (8) to cause its retraction. <IMAGE>

Title: Reclaiming metal from scrap
Inventor: RILEY ERIC KEITH
IPC: F27D99/00
Filed: 1990-07-06
Abstract: The noxious fumes leaving the dry hearth chamber (112) of a metal recovery furnace (102) are fed to an incinerator (106) where they are burnt at high temperature with oxygen. The hot, clean exhaust gas is introduced to the bath chamber (111) of the furnace (102). This arrangement typically saves 60 % of fuel costs. Furthermore, since the fumes are recycled the exhaust emission to atmosphere simply reflects the input of fuel and oxygen. This can be nearly one eighteenth of a conventional plant thereby reducing filter and/or scrubber duty and stack size. This arrangement thus has particular advantages in fuel conservation and conservation of the environment. It enables metals to be recycled in an installation which produces little pollution and which utilizes the heat available in the waste material to conserve fuel.

Title: Web roll support in splicing machine
Inventor: CHEN SHENG-MING
IPC: B65H19/18
Filed: 1991-03-14
Abstract: A material dispensing machine includes roller sets (110 and 120) adapted to receive thereon rolls of web material and an end-joining device including an adhesion arm 213 and suction plates 214. Material from a first roll on a first roller set (120) is held in reserve whilst material is dispensed from a second roll on second roller set (110). When the roll on the second roller set (120) is nearly unwound, the initial end of the first roll is joined to the material of the second roll whilst the two roller sets are rotated by a motor to swap positions. The mechanism effecting the rotation is made up of a gear mechanism (131, 132, 133, 134) which rotates the frame of the roller sets about individual separate axes whilst rotating both roller sets about a third common axis to keep the longitudinal axes of the rolls of material on the roller sets substantially horizontal throughout the rotation. <IMAGE>
Patent GB-2253718-A (GB)
Title: Controlling photographic exposure
Inventor: TUBBY RICHARD JEREMY
IPC: H05B37/02
Filed: 1991-03-14
Abstract: A method of controlling operation of a number of lamps (10) illuminating a subject (12) during a photographic exposure. Before the exposure, the power supplied to each lamp is adjusted by the photographer to give the desired illumination of the subject, and the power input to each lamp is measured and recorded. During the exposure, each lamp is switched on at full power for a time period calculated to produce the same effect on the photographic film as exposing the film to the lamp at the measured power input for the desired exposure time. The time period for each lamp is calculated by making the ratio of the time period to the desired exposure time equal to the ratio of the measured input power to the value of the full power input. Apparatus for carrying out the method includes a computer programmed to carry out the calculation for each lamp. The computer may also be used to control a separate power controller for each lamp to switch the lamps on and off for the calculated time periods. The method and apparatus avoid the problem of colour temperature shift when dimming lamps, particularly tungsten lamps. <IMAGE>

Patent GB-919914-A (GB)
IPC: G05D16/20
Abstract: 919,914. Automatic pressure control systems. BENDIX CORPORATION. Jan. 24, 1961 [Feb. 1, 1960], No. 2786/61. Class 38 (4). An automatic electrically-operated multivalve system for controlling the pressure inside a test chamber including a pressure sensor instituted by an electromagnetic differential device, comprises a number of electrically operated bleed valves controlled by the output of the differential device. As shown, a test chamber 165 is connected to pressure line 160 through a large-bore solenoid-valve 155 and a small-bore solenoid-valve 156 and to a vacuum line 190 through a large-bore solenoid-valve 185 and a small-bore solenoid-valve 186. The pressure in the test-chamber is sensed by a bellows capsule 83 which positions a soft iron vane 65 of a detector 63 having an E-shaped element 61 positioned in dependence on the desired temperature, as set on a potentiometer 11, by a servomotor 43 which also drives a follow-up potentiometer 17. The E-shaped element carries an exciting coil 73 and the output from coils 75, 77, representative of the pressure deviation, is applied through an amplifier 92 to a winding 96 of a servomotor 98 positioning an actuating member 106 of a control switch. The member 106 is centre-biased by a spring-loaded contactarm 109 and is damped by a dash-pot 124. Contact-arm 110 or 112 is engaged by the contact arm 109 when the pressure in the capsule is outside of desired limits. Initially, on closure of a switch 138 the deflection of the bellows 83 causes the motor 98 to close the appropriate contacts to energize a relay in a relay system 143 to actuate the appropriate large bore valve 155 or 185. The rapid change in the test chamber pressure causes the pressure to over-shoot so that to avoid oscillation the control switch 108 is isolated for a duration determined by a timedelay relay in the relay system 143. After the delay the large-bore valve 155 or 185 is closed and the pressure balanced, without overshoot, by the small-bore valve 156 or 186. At balance a lamp 320 lights, indicating that the chamber is at the desired pressure.
