Title: Improvements in or relating to electronic flash units
Inventor: NAKAJIMA YUKIO
IPC: G03B7/16
Filed: 1979-07-03
Abstract: An electronic flash unit for use with and/or mounting on a camera with an electrical shutter has a flash discharge tube, a main capacitor for discharging the flash discharge tube, and a flashlight illumination detector circuit connected in the discharge path of the flash discharge tube for producing a signal which can be applied to a terminal of the camera electrical shutter circuit to enable an auxiliary shutter closing means for enforcing closure of the shutter.   In an electronic flash unit, a discharge detector circuit responsive to discharge through the flash tube provides an externally available electrical signal which can be transmitted to a camera to enable a shutter closing circuit therein.

Title: Magnetic torque generator
IPC: H02K25/00
Filed: 1982-01-07
Abstract: A magnetic torque generator comprises a disc 11 carrying equally spaced permanent power or rotor magnets 15, 16, the disc being on a rotatable shaft 12 so that the magnets move in a circular path below which a trigger or stator permanent magnet 18 is disposed. The trigger or stator magnet is oscillated or rotatably moved in one direction continuously so that alternating poles of the trigger or stator magnet change positions constantly whereby the trigger magnet attracts the adjacent power magnet part of the time and repels the adjacent power magnet part of the time. A timer is operably coupled to the trigger or stator magnet for selectively energising the trigger or stator magnet. Electromagnet 23 is oscillated via shaft 12 movement in Fig. 4 (not shown) the trigger magnet is rotated mechanically via gear boxes connected to the disc supporting shaft. Rectilinear motion is provided in the reciprocating engine of Fig. 5 (not shown). <IMAGE>

Title: Cleaning arrangement and method for process plant
IPC: F28G9/00
Filed: 1982-03-17
Abstract: One perennial problem with clean- in-place techniques in plate heat exchangers is that solid material trapped by the obstructions is not easily dislodged, even if the conventional back-flushing is used. According to the invention, the various runs in the cleaning cycle are in alternate directions through the plate heat exchanger which has been found to give an adequate removal of such solids material as orange cells. Detergents e.g. caustic solutions may be used in part of the cycle; otherwise water e.g. for flushing and pre- washing.

IPC: B44C5/00
Filed: 1982-07-14
Abstract: A backing sheet printed with a pattern has secured to the pattern a cloth or textile of openwork structure so that the printed pattern is visible therethrough. The pattern and the cloth or textile, and their mutual arrangement, are such that a visible optical interference pattern is produced, in particular a moire or watered silk effect. The printed pattern may be an image of cloth or textile for example of the same or similar structure as that secured to the backing. The printed pattern and the cloth or textile may be of various designs to achieve a variety of the different moire effects known in the textile art. The finished product has the appearance of genuine moire fabric cut but can be produced without the elaborate techniques normally required to make such genuine fabric.

Title: Air conditioning system
Inventor: WRIGHT GEORGE PETER
IPC: F25D16/00
Filed: 1983-06-13
Abstract: Air from a room 10 to be conditioned is passed through respective channels in a module 11 as a plurality of mutually parallel streams. In each channel, the respective air stream passes sequentially over a cooling coil 24 and also over an expansion coil 15 of a compression refrigeration system which also includes a condenser 16. The coils 15 and 24 in each channel are selectively operable so that the respective air stream is either cooled by the refrigerant in the coil 15 with the heated refrigerant subsequently being cooled by a water/glycol mixture in the condenser 16, or is cooled by the same water/glycol mixture flowing through the coil 24. In both cases, the heated water/glycol mixture is passed to dry coolers 18 where it is cooled by the ambient external atmosphere. A sensor 25 is responsive to the temperature in the room 10 and operates to bring the coils 15 and 24 selectively into operation from channel to channel in accordance with that temperature. <IMAGE>

Title: Friction brake incorporating a ball and ramp drive mechanism
Inventor: RIEGER PAUL
IPC: F16D55/50
Filed: 1983-12-05
Abstract: A power brake, in particular for braking the free end of a shaft, includes an electromagnetically or hydraulically operated actuator which, when it is acted upon by an appropriate signal, serves to press a friction disc (22) against a stationary stop (26), thus braking it. The friction disc (22) is connected, so as to follow its rotation, to a shaft sleeve (24) on which the driven member (32) of a ball and ramp mechanism is axially displaceable but rotates along with the shaft sleeve (24). The driving member (34) of the ball and ramp mechanism is connected to the end of the shaft which is to be braked. The ball and ramp mechanism has friction discs (38) which rotate with the driven member (32). In cooperation with the driven member (32), the friction discs (38) cause the driven member (32), driving member (34) and thus the end of the shaft to come to a full halt when the shaft sleeve (24) has been braked and caused the driven member (32) to be displaced axially against the force of a biassing spring (36). <IMAGE>
