Abstract: 1388207 Cassette player-recorders; function selectors MOTOROLA Inc 1 Dec 1972 [6 Dec 1971] 55617/72 Heading G5R A cassette player-recorder includes a function selector 42 which is automatically released from its record position if a tape driven control 26 is operated, to prevent fast-forward or fast-rewind drive in the record mode. The cassette is also ejected. The function selector is as described in Specification 1,356,900. Actuator bar 22 is moved sideways as at 102, 104 to select fast transport, and this is transformed to motion of a slide 124 in perpendicular directions 148, 150 by means of a lever 108 pivoted on a pin 109. The lever 108 has a channel 116 in which is received a pin 114 on the bar 22, and is also attached to the slide 124 by a pin 144. A pin 152 on the interlock arm 66, which arm retains the selector 42 in its depressed record position, is received in a V-shaped channel 154 in a cam 146 on the slide 124. Movement of the slide 124 in either direction 148, 150 thus raises the pin 152 and pivots the arm 66 counter-clockwise to release the selector 42. A switch 92 is then also opened, actuating a solenoid-operated cassette ejection device.

Abstract: 1,189,040. Displacement digitizer. OLYMPUS OPTICAL CO. Ltd. 26 Nov., 1968, No. 55923/68. Heading G4H. [Also in Division G1] The sense in which the phase of a cyclically varying signal, e.g. a Moire fringe pattern, is progressing is detected by producing signals phase displaced on either side of the basic signal by 90 degrees, e.g. by three spaced photo-cells, and subtracting the two signals in each adjacent pair to produce two further signals which are spaced in phase by 90 degrees and which may be applied to a conventional direction sensing circuit. The arrangement produces less phase variation for a given variation in characteristics of a pair of photo-cells than a corresponding system in which four photo-cells spaced by 90 degrees are used, the outputs of alternate photocells being subtracted.

Abstract: 1445572 Radar proximity fuze DEFENCE SECRETARY OF STATE FOR 22 Nov 1973 [6 Dec 1972] 56322/72 Heading F3A [Also in Division H4] A receiver for detecting signals which are phase-modulated according to a digital code sequence includes a decoder for applying a sequence of phase shifts, complementary to those given by the code sequence, to received signals. As applied to a radar proximity fuze, the same code generator is utilized for the transmitter and the decoder, a suitable delay in the line to the latter affording detection at a particular range. A bi-phase code as in Specification 1,432,541 is used in the embodiments. In one embodiment a bi-phase code generator 3 feeds a microwave transmitter and, via rangedelay 6, to a balanced mixer 2, with a target at the range corresponding to delay 6 the output of the mixer is a series of pulses of constant phase at ZF. A one-bit delay 7 is introduced into one path from the mixer to a phase-detector 6. If the inputs thereto are in phase the output is a D.C. voltage of one polarity and are applied to an integrator 9, and thence to a low-pass filter 10 (for rejecting out-of-range target signals) and a threshold circuit 11 to trigger a fuze. An alternative embodiment utilizes surface-wave delay lines between the output of mixer 2 and the upper junction of mixer 2 and delay 7, Fig. 2 (not shown), and is useful when the wanted signal is buried in noise.

If the images of an infinitely distant point P appear on picture 4 as P R , and on picture 2 as P'L, then the pictures are so arranged that the distance of P R  from the partition line 6 between pages 1 and 3 is greater than the distance of P'L from the same line, by an amount approximately corresponding to the normal interpupillary distance of an adult person. A preferred distance is within the range 40-65 mm. For a further improvement in the proper perception of perspective and depth, the product of the linear magnification of a component picture and the focal distance of the lens of the taking camera should be the same for both pictures, and approximately equal to the normal viewing distance.

[Also in Division C3] A strippable protective coating is formed on a substrate by spraying thereon a molten composition containing (i) a film-forming ethylenevinyl acetate copolymer and (ii) a polymer of lower molecular weight which reduces the melt viscosity of the composition and thus lowers the melt-spraying temperature (see Division C3). The composition may be sprayable below 200‹C, and the substrate may be heated up to 80‹C to prevent premature cooling of the sprayed droplets. As shown, the molten composition 5 is contained in a heated thermostatically-controlled vessel 4 and is passed by a reciprocating pump 3 to a spray nozzle 12 via a pulsation damper 6, a burst disc 7 and a hose 9. Filters are provided at 11 and 8. The apparatus may be heated and insulated.
