Title: Positive-negative photographic image transformation - divides coherent light beam into two phase displaced beams
IPC: G03C5/08
Filed: 1973-04-20
Abstract: Method of photographic image inversion in which all colours are made reversible, proportional, complementary adaptable to viewing or printing. A luminous beam is divided into a direct beam passing through image and onto a work plane and a phase displaced parallel beam projected onto the same work plane and interfering with the direct beam. A laser (1) emitts a coherent light beam (2) which is divided in two by a semi transparent mirror (3), prism etc. The direct beam (2a) follows a normal route through a condenser (4) a negative (5) an objective (6) and is projected onto a work plane (7) or a photo sensitive emulsion. The reference beam (26) deviated by the semi-transparent minor (3) follows a parallel path via the mirrors and passes through a half wave lens (10). The reference wave (26) is phase shifted with respect to the direct wave (2a) by half lambda. The phase shifted wave (26) is projected with the helf of condenser (11) onto the work plane (7) and interferes with the direct ray (2a).

Title: Lightweight mixture static separator - has suction device with inclined parallel sheets over which mixture slides
IPC: B07B9/02
Filed: 1973-09-04
Abstract: The separator is for handling three materials of roughly equal densities, and incorporates a suction device comprising inclined parallel sheets assembled into a staggered venetian-blind pattern.

Title: Continuous weld quality control monitor - by infra-red radiation detector output signal compared with desired reference signal
IPC: B23K11/25
Filed: 1973-09-20
Abstract: The quality of a weld (spot weld) is controlled by directing on it a detector of the infrared radiation. An electronic circuit produces a signal proportion to the heating intensity which is compared with a reference signal representing the desired heat input in the weld. A control signal is produced as soon as the measured signal exceeds the reference signal. This system is less complicated than ultrasonic testing; it requires no coupling fluid and can be used for thinner workpieces. It requires no probe which may be damaged by surface roughness and is less complicated than dilatation tests.

Title: Telecommunication switching equipment - interconnects transmitters and receivers by generating pseudo random coded signals
Inventor: MIRABEL LOUIS GASTON PIERRE
IPC: H04W88/14
Filed: 1974-10-11
Abstract: A telecommunication switching equipment can interconnect a number of pairs of terminals. Each terminal is connected to a transmitter and a receiver of signals. The transmitters and the receivers are situated such that each transmitter sends to all the receivers a signal which is practically the same for each transmitter. Each transmitter can generate a pseudo-random coded signal which phase modulates the transmitted useful signal. Each receiver has a demodulator and a correlator whose local signal is phase modulated by a pseudo-random signal supplied by a generator similar to the generator of the transmitter. Each receiver can be controlled by signals such that the generator of coded signal in the transmitter and the generator in the receiver can generate similarly coded signals.

Abstract: 1441067 Seaming non-metallic sheet material IMPERIAL CHEMICAL INDUSTRIES Ltd 21 March 1975 [16 April 1974] 16446/74 Heading B5K Two thermoplastic polymeric sheets are seamed together by causing the sheets to converge and directing towards the line of convergence at least one focused beam of energy from a laser. The sheets may be films or knitted woven or non-woven fabrics containing thermoplastic continuous filaments or staple fibres, e.g. crimped polyester fibres. During seaming, the sheets may be held stationary relative to each other and to the laser beam or there may be a stepwise or continuous relative movement between the laser beam and the sheets. If the laser beam is movable, its position relative to the sheets may be controlled by a programmer e.g. a punched tape or a magnetic tape. The sheets may be brought together by passing them bwtween two plates, around two bars or between two moving belts. The laser beam, which is preferably pulsed or chopped, may be oscillated over a narrow width to produce a seam comprising two or more rows of weld points. After seaming, the fabric may pass into a laser cutting device controlled by the same programmer which controls the seaming laser. As shown, apparatus for seaming together two fabrics to produce garments comprises fabric supply rolls 1, 2 and driven nip rolls 3, 4 to bring the fabrics together. Two pulsed laser beams 5, 6 are traversed along the nip 7 be tween the rolls 3, 4, the speed of the rolls 3, 4 and the positions of the beams 5, 7 being controlled by a computer. The seams form shoulder seams 10 and side seams 9 of a dress which is subsequently cut-out.
