Abstract: 1487004 Controlling light; automatic control of direction CARL-ZEISS-STIFTUNG [trading as CARL-ZEISS] 20 Jan 1975 [25 Jan 1974] 2331/75 Headings G2F and G3R In a system wherein a tunable laser beam is mixed with a further laser beam, or frequency multiplied, in a non-linear crystal 3, the crystal is retroactively controlled so that the converted beam has the same optical path whatever the frequency of the tunable beam. In Fig. 1, alteration of the tunable beam leads to non-collinearity therewith of the converted beam, such displacement being sensed via a partial mirror 11 and photo-cells 12, 13 coupled to the differential inputs of an op-amp 14. The output controls a servomotor 5 for rotating the crystal until the outputs of cells 12, 13 are equal. To prevent lateral displacement of the beam due to rotation of the crystal, the crystal is immersed in a refractive index matched liquid 35, or followed by a second contra-rotated crystal, Fig. 2 (not shown). In a second embodiment, Fig. 3 (not shown), the temperature and hence the refractive indices of the crystal towards the various optical frequencies are controlled by the output of amplifier 14.

Title: System for codifying data
IPC: G07C9/00
Filed: 1975-01-21
Abstract: 1490794 Codifying data COMPAGNIE GENERALE D'AUTOMATISME 21 Jan 1975 [22 Jan 1974] 2554/75 Heading G4B A system for codifying data comprises a receptacle in combination with a mechanical memory device. The memory device has several fingers 5 each attached to a respective slide 2 resting on beams 3 and 4 inside a box 1; each slide being movable by means of a stud 26 which can engage a notch 22 in the slide. Each stud 26 forms part of a bay (Fig. 4) which is inserted into the box 1 and turned to effect movement of said slides 2. The length of each stud 26 corresponds to a particular size notch 22 in a particular slide 2 so that the key cannot be operated when wrongly located relative to the slides 2. Rotation of the key in the direction indicated by the arrow 23 (Fig. la) causes the slides engaged by the studs to move to a forward position in which the respective fingers 5 protrude through openings 8. Each slide may be locked in the forward position by a spring- loaded catch 9 which may later be disengaged by pulling on a pull rod 13, after which the slide will return to a rearward position due to the action of a spring 14. The presence of a stud 26 on the key represents a one in binary terms whilst an absence of the same represents a nought. Thus when the key is inserted and rotated in the box 1, the fingers 5 which are caused to protrude through openings 8 each represent a binary one while those which remain retracted represent a nought. The mechanical memory device is accommodated in a receptacle (Fig. 5, not shown) having a face (34) with as many holes (35) as the memory device has fingers each hole having an electrical contact which is actuated by a respective finger 5 when said finger protrudes through a respective opening 8.

Abstract: 328,302. Davies, J. Jan. 25, 1929. Magazine gramophones; driving; returning sound-box to starting point.-A magazine gramophone tips a record from a magazine into position to be received by a turntable in rising'to playing position, then turns over the record to play the other side, and drops it down a shoot into a bottom cabinet, and then receives a fresh record. Turntable 55 is raised to playing position by reversible electric motor 21 geared to chain sprocket 27 which pulls on wire cable 29 to pull the table up, the table being guided by pulleys 16 running on square rod 15. In rising, the turntable 55 engages with a long cam rod 63 attached to the pick-up 51 to swing the pick-up from the inner leaving-off position to the outer position for starting playing. This swing out of the pickup short circuits contacts 69, 71 to stop the raising motor 21 and to start the motor 57 driving the turntable. The swing-out of the pick-up is limited for 10" and 12" records by stops 64, 65, respectively, engaged by rod 70 or the pick-up. A played record in passing to its discharge magazine 104<1> operates mechanism to tip an unplayed record from its magazine 72 by depressing a trigger 85. This raises a T-piece 79 which pushes up the bent clip 77 of a spring rod 75, which engages the edge of the record and tilts it out of its compartment over a wedge block 74. The rod 75 passes through a loop in rod 78, which is initially pushed in by a hand-knob 84, so that the bent-up end 76 engages the side of the furthest record, and as each record is tipped out, the spring in the rod 75 causes its end 76 to engage the side of the next record to be tipped out, and so on. When a record is tipped out, it slides down a shoot 102 and engages and resets a deflector 105, Fig. 5A, to mask the discharge slot 104, Fig. 5B, and rests against stops 110. The record deflector 105 is made of spring metal and pivoted so that in one position one arm masks the slot 104 for reversing sides, and when reset its other arm deflects the record into the discharge shoot 104. A tray 112, with a hole in its centre for the turntable to pass through, is tilted by a projection engaging an arm 117 to transfer the record to the tray, which is then received on the rising turntable. Reversing record. When the turntable is descending, the record is tilted, Fig. 1A, by a stop 119 and slides on to a tray 86. On further descent, a fork 99 depresses a hinged arm 94 and tilts the tray 86 to the vertical by means of rod 93. The record in falling on deflector 105 slides down a bracket 108 and comes to rest against stops 110 with the reverse side up. Further descent releases the tray 86, so that a spring 125 returns it to normal, and on still further descent a projection on an arm engages the arm 117 and tilts the tray 112. The record being raised over stops 110 by tongues 115 slides on to the tray 112 whence it is again lifted on to the uprising turntable.
