Title: Optical switching network
IPC: H04B10/27
Filed: 1973-02-06
Abstract: 1422864 Automatic exchange systems; controlling light PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 6 Feb 1973 [9 Feb 1972] 5836/73 Headings H4K and H4F In a switching network in which electrical inputs and outputs are selectively interconnected by light beams which are deflected on to selected output devices, the deflection system is controlled by at least one light beam and is responsive to the angle of incidence thereof. As shown light from a coherent light source LS is split into N separate beams by a beam splitter V (employing double-refractive prisms or multiplex phaseholograms) and projected by mirror T2 and optics P1 on to separate modulators LM (forming part of an integrated matrix described below) controlled by the individual electric input channels to be switched. The refracted and digital amplitude modulated resultatnt beams are reflected at SP 1  on to associated holograms H1 to H4 each instantaneously storing the image of a beam directed in accordance with the required output AF 1  to AF 4  such that the resultant output is a beam directed towards a selected detector El to E4 and digital amplitude modulated. The signals switched may be video telephone signals binary coded to reduce the effects of noise and allow the detectors and modulators to be closely located. to set up a required connection between a given input and a given output the hologram H 1  to H 4  associated with that input must be erased and a new image recorded directed in accordance with the required output. To effect this a beam from source LS is deflected by a digital light deflector DL on to one lens of a fly's eye lens unit FLA the particular lens selected corresponding to a particular input and thus a particular hologram. Each lens is of a curvature such that the whole of an electronically controlled mask MS is illuminated. Only one portion of the mask corresponding to the required output is rendered transmissive. From each portion the beam L2 to the selected hologram is directed in a different direction and thus by selecting a portion associated with required output a beam directed in the appropriate direction can be recorded. The light modulation matrix LM and the digital light deflector DL may be replaced by matrices of laser diodes. The light modulator matrix Fig. 8a comprises an electro-optic plate PLO and a double-refractive prism PR1 which functions as a polarizer and an analyser. Linearly polarized light EW enters the plate via the prism, one aperture of a mask MS<SP>11</SP> and a transparent electrode Sch and after reflection at a corresponding electrode ME returns over the same path. If a potential is applied to that electrode the polarization of the light changes in the plate and on return is refracted at a different angle (the signal path).

IPC: B41F19/06
Filed: 1952-03-06
Abstract: 734,502. Embossing machines. MASSON SEELEY & CO., Ltd. March 6, 1953 [March 6, 1952], No. 5903/52. Class 100 (2). In an embossing machine the work is supported during a marking operation on a platform mounted resiliently on the lower platen of the press and shaped so that a slot is formed between the platform and the lower platen, the same or other work also being passed through the slot for a supplementary operation effected by means mounted on the upper face of the slot and on part of the lower platen. As shown in Fig. 1 the press comprises an upper platen 3 mounted on a vertically reciprocable plunger in head 2 and a lower platen 4 adjustable vertically on the upright 1. The main marking operation is effected by dies on the platen 3 and the upper surface of the platform 13, pigment carrying foil 21 being fed from spool 5 and taken up on spool 6 and a strip 22 forming the work to be marked being fed with the foil 21 between the platen 3 and platform 13 over guide rollers 12. Foil 21 and strip 22 are fed together by nip rollers actuated by a ratchet driven through lever 9 and link 10 from the reciprocating mechanism of the press as described in the Specification 728,391. The work having been marked is returned through the slot 16 beneath the platform 13 to a take-up spool 8. As shown in Fig. 2 the platform 13 is recessed in its under face and mounted on blocks 14 of rubber or the like (or springs) which are compressed as the upper platen 3 moves downwardly against the upper surface of the platform. A toothed perforator 17 secured to the lower platen 4 is arranged to perforate the strip 22 each time the platen 3 descends. A backing pad 18, e.g. of cardboard is secured to the upper surface of the slot to receive the teeth of the perforator after they have passed through the strip 22. As the strip moves through the press the main marking and supplementary operations are thereby effected simultaneously on different parts of the strip. The supplementary operation may also be a marking operation effected by dies mounted on each side of the slot 16. Pigment foil may be fed through the slot for this purpose. The means effecting the supplementary operation may be adjustable on the lower platen for registration, and the resilient support blocks may be provided with means, e.g. screwthreaded distance pieces for varying the height between the platform or the lower platen may be heated. The supplementary operation may alternatively result in another transfer marking in a different colour; an embossed impression; the marked portion having parts cut away or the marked part being cut out of the strip.

The ends A' of the roller are mounted in blocks M sliding in vertical grooves E against springs X encircling pillars Z' engaging recesses N<2> in the blocks M. The roller is fitted with plates carrying brushes A<3> in grooves A<2> between the ribs AA, the plates being secured in pairs by screws A<4>. A lever R<3> pivoted to a projection O on one of the blocks M is connected to a lever R<2>, one end of which is adjustably pivoted at S to the pillar Z' and the other end of which is connected bv a pin and slot connection to a weighted lever R secured to a spindle J mounted in bearing blocks I mounted in channels H in the sides of the box. A brush ring K<1> is fitted around a wheel K secured on the spindle J, a ratchet free-wheel device being fitted between the ring K<1> and the wheel K. An arrester plate P is resiliently mounted on the projections O of the block M by pillars PP and springs, to bear against the roller. A check-spring L bearing against the ring K<1> is mounted on one of the bearing rollers I. In operation, as an axle passes over the apparatus in contact with the roller A, which is of larger diameter in the centre, the roller is caused to rotate because of the helical ribs AA and is depressed against the action of the springs. Through the system of levers, the spindle J is rotated and with it the brush ring K<1>, which supplies oil from the box B to the brushes A<3>: which supply oil to the axle. When the axle has passed over, the roller rises, but the ring K<1> remains stationary, due to the check-spring L and the free-wheel mechanism. The roller is brought to rest by the braking action of the plate P. Buffers T, secured in recesses V in the ends of the box by bolts D, have projections W engaging reduced parts of the blocks M to limit the upward movement of the roller. The ends C of the box are wedge-shaped and are formed with brackets G. An angle-iron Y is secured to the rail side of the box, the vertical side being bent of alignment at the ends to serve as a guide for the wheels of the corve.
