Abstract: 1,151,201. Microfilm projection readers. SPERRY RAND CORP. July 12, 1966 [Aug. 2, 1965], No. 31181/66. Heading G2J. A microfilm reader apparatus projects an image formed on pressure-sensitive film held at station 31 on to a screen 35 and has pantograph linkage means 45 inter-connecting a hand-held input pen 46 and a marking stylus 44 whereby miniaturized markings may be made on the film during projection. The film is preferably of the type having a thermoplastic coating in which vesicular images are formed, such images being marked when the vesicules are destroyed by pressure from the stylus. The fixed output pivot of the pantograph may be disposed on either side of input arm 58 to give optional mirrors reversal of the traced image. This pivot may also be adjusted to any of four positions through spring detent, to give coverage of four overlapping sectors of the microfilm. Pen 46 is scrived mounted on input arm 51 and carries a micro-switch which is closed by downward pressure to energize a rotary solenoid driving a cam to lower the hinged stylus 44 on to the film surface. The stylus is automatically raised when the pen is lifted. A safety device retracts the stylus if it moves outside the area of the microfilm frame.

Patent GB-315379-A (GB)
Title: Repeating device for gramophones
IPC: G11B3/095
Filed: 1928-10-30
Abstract: 315,379. Schwanke, E. July 13, 1928, [Convention date]. Returning sound-box to starting point. - Repeating mechanism for gramophones consists of a running- wheel g which is geared to a member adapted positively to raise and to lower the tone-arm at the required positions, and the wheel is arranged at such an angle in relation to the tangent to the record groove at the point at which the wheel contacts with the record that it carries the tone-arm towards the outer periphery of the record. A pinion 6, Fig. 1, which is fixed on the axis of the wheel g, is rotatably mounted in a member slidable in a guiding member 23 fixed to a part 7 carried by a clip d on the tone-arm a. A non-circular toothed wheel 1 rotatably mounted in the member 23 is adapted to engage the pinion 6, but is provided with a toothless gap 8 wherein the pinion runs idly during playing of the record. The initial rotation of the wheel 1 is effected by a weight 2 fixed upon the spindle of the toothed wheel 1, and normally held in raised position by an arm 3, Fig. 6. The arm 3 co-operates with a feeler device 4 so that when the latter contacts with a fixed stop, such as the turntable spindle f, the weight 2 is caused to fall, the pinion 6 and wheel 1 to engage, and the tone-arm to be raised. The feeler device is previously set in position according to the desired point of operation of the repeating mechanism. The shape of the wheel 1 is such as to raise the tone-arm rapidly and lower it gradually. The running-wheel g may be held out of contact with the record during playing by means, such as a spring, and released so as to engage the record at the same time as the weight 2 is released by the device 4. The arm 3 is adapted to re-engage, for example by spring action, with the weight 2 to maintain the device in inoperative position until it reaches the inner limit of adjustment determined by the feeler device. In an alternative construction, the wheel 1 may be mounted on an arm pivoted to an L- shaped part on the part 7, or the running wheel g, toothed wheel 1, and a cam 9 may be mounted in a cranked lever 24 pivoted to a part 11 which carries, as shown in Fig. 3, a roller 10 engaging the cam 9. If desired, the roller 10 may be mounted on a separate lever pivoted to the lever 11 and may be adjustable vertically by a setscrew or weight. The running wheel g may be adjusted in vertical direction by mounting the part 7 in a sleeve 19 and actuating a screw 30, Fig. 10. Angular adjustment of the wheel g is effected by a knob 27 which rotates a worm 18 engaged by an extending arm on th'e sleeve 19. Alternatively, the device may be adjustable longitudinally of the tone-arm, in which case the running-wheel g and parts 11, 24 are movable in a guide 29, Fig. 11, by a screw 28. A pointer moving over a scale may be provided in connection with the adjustment means. The guide 29 may be of sinuous shape.

Title: Improvements in or relating to television systems
IPC: H04N7/12
Filed: 1945-11-21
Abstract: 606,145. Transmission systems. RUDKIN, E. P. Nov. 21, 1945, No. 31425. [Class 40 (iv)] [Also in Group XL (b)] In order to avoid the use of an ultra-high frequency carrier in a television system employing video signals covering a wide frequency band, e.g. up to 20 mc/s. the video signal band is split up into a plurality of sub-bands which are used to modulate separate adjacent carriers, each carrier being amplitude-modulated by one sub-band and frequency or phase-modulated by another. The video signals are developed in the iconoscope 1 to which line and frame frequency signals are applied from the generators 8 and 9 which are synchronized by the master oscillator 10. The output from the oscillator 10 is suitably frequency-changed at 11 and used to synchronize the oscillators 02, 03 ... O10. The video signals which in the example described cover a band of 0-20 mc/s. are separated into bands 0.2 mc/s., 2.4 mc/s., ... , 18-20 mc/s. by the filters F1, F2 ... F10 respectively. The outputs from the filters F2 ... F10 are heterodyned in units C2 ... C10 with the outputs of the oscillators 02 ... O10 which are such that the output of each of these units lies in the band 0-2 mc/s. as does the output from F1. Carrier frequency sources R1 ... R5 are provided, operating on adjacent frequencies and are frequency-modulated by the output signals from F1, C3, C5, C7, C9 respectively and amplitude-modulated by the signals from C2, C4, C6, C8, C10 respectively. The outputs obtained from the modulators M1 ... M10 are fed to the transmitting aerial system. At the receiver, the ten channels are separated out by conventional means and the video-frequency sub-bands in the range 0-2 mc/s are heterodyned back to their original frequency bands by means of oscillators synchronized from the received line and frame synchronizing signals. The heterodyning oscillations may alternatively be transmitted to the receiver upon a separate carrier ; if they are harmonically related a single synchronising modulation is sufficient.

Abstract: 207,372. Sainrapt, (nÚe BÚlard), I. P., and Soc. des Tuyaux et AgglomÚrÚs Centrifuges. Nov. 17, 1922. Overlap joints with ,packing compressed radially on assembly.-An elastic joint for ferroconcrete and other pipes is formed by two rings of rubber or other elastic material which are compressed both radially and longitudinally on to the two pipe ends by means of a retaining metal band or ring. In the form shown in Fig. 1 the edges of the metal ring 2 are provided with teeth which on being turned down compress the rings 1, 1' radially and longitudinally. The packing rings are prevented from being drawn together by means of the peripheral channel 4; the latter however may be replaced by an annular distance piece fitting within the ring 2. In order to prevent longitudinal displacement of the pipes, flanges on the ends of the pipes may be provided or as shown in Fig. 4, the edges 9 of the retaining ring may engage peripheral channels 8. In a further modification, the radial and longitudinal compressions of the packing rings are produced by forming annular depressions in the retaining ring immediately over the packing rings. The metal ring may be protected by coating with tar, varnish, enamel, or similar material and it may be entirely covered on the outside by a layer of cement &c.
