Patent GB-278210-A (GB)
Title: Phonograph recording machine
IPC: G11B3/36
Filed: 1926-11-29
Abstract: 278,210. Beatty, W. E., (Western Electric Co., Inc.). Nov. 29, 1926. Feed and return mechanism; records.- The invention comprises apparatus for recording on records so that the initial grooves thereof are pitched a.t a greater distance apart than the subsequent grooves in order to facilitate application of a reproducing stylus, this feature being specially serviceable in connection with talking cinematographs to obtain synchronism. A base 10 supports a motor 12 which drives a record support 13 and also, through worm gearing 64, 63, shaft 60, and a longitudinally yielding clutch comprising a spring 59 and disc 58, a feeding screw 20 bearing at its rear end in a bush 31 arranged to have longitudinal movement in its supporting bracket 32. The recorder 25 is carried by an arm 24 vertically adjustable on a guide 21 upstanding from a carriage 19, which is normally traversed, for recording, by the screw 20 engaging a spring- pressed half nut, return being effected by a pinion 53 which can be moved into gear with a fixed rack 54 and manually rotated by a hand wheel 51. To ensure that the pinion 53 and rack 54 shall never be engaged at the same time as the half nut and screw 20, the pinion and the hand wheel are secured on a cross shaft 52 carrying a cone cam 45 which rocks a pivoted lever 4& to disengage the half nut against spring pressure as the pinion is moved into gear. As the carriage is moved inwards to starting position the end of the cross shaft 52; bears against, and rocks, a bar 67 fixed on a spindle carrying an arm 69 which lies in the path of a pin 70 on the clutch disc 58. In operating the machine, the stylus is adjusted by the aid of a pointer 74 and scale 75 to the position for the end of the innermost groove, and the motor is started and drives the turntable and the screw 20, the pin 70 rocking the arm 69 and bar 67 to push back the cross shaft so as first to disengage the pinion and then allow the half nut to engage the screw. During this action the screw, together with its slidable bearing bush 31, is being moved longitudinally by a face cam 44 clipped on the screw and acting on a roll 43 mounted on the support 32 so that the first grooves cut in the record have a relatively large pitch. When the highest part of the face cam contacts the roll, a recess 38 in the bush 31 is opposite a spring plunger 39 which now rocks the bush so that the further traverse of the stylus is effected wholly by the screw 20 and half nut. A fixed pointer 72 and a mark 80 on the clutch disc 58 facilitates setting of the screw and cam 44 in starting position. Specifications 170,870 and 262,839 are referred to.

Title: Improvements in or relating to rolling mills

Filed: 1972-06-29
Abstract: 1379108 Rolling mills T SENDZIMIR 29 June 1972 30549/72 Heading B3M A mill for rolling flat articles (e.g. strip) includes a pair of work rolls 7 (Fig. 2), each being backed by a series of castors 6 and 6<SP>1</SP> carried on shafts 5 and 5<SP>1</SP>, the shafts being so supported in eccentrics 3 and 3<SP>1</SP> that simultaneous or individual rotation of the eccentrics causes the castors 6 and 6<SP>1</SP> respectively to adjust the roll position or the roll crown. Each eccentric is supported in a saddle plate 1 (Figs. 1 and 2) mounted in the mill frame 2. The eccentrics may be rotated by toothed sectors 8<SP>1</SP> secured to them, or by vertically positioned hydraulic rams (Fig. 4, not shown). In the latter case the saddles may be cut away to accommodate the lever arms associated with the rams. Each sector 8 meshes with a toothed sleeve 10<SP>1</SP> carried on a common shaft 11<SP>1</SP>, the shaft being rotated by an actuator 13<SP>1</SP> to rotate the sleeves and hence adjust the roll gap. The sleeves are axially adjustable along the shaft 11<SP>1</SP> by individual worms 15<SP>1</SP> and annuli 14<SP>1</SP> to distribute the torque applied to the sectors. The upper work roll need not be adjustable. Two pairs of work rolls may be provided in a skin passing mill (Fig. 5), only one pair being used at any time. The shafts 5<SP>11</SP> located between the rolls are movable between two positions to cause the associated castors to move one or other roll to be shifted to a working position. Strip being rolled in the mill passes around tensioning rollers 28, 29 and 28<SP>1</SP> 29<SP>1</SP>, the tension across its width being measured by sensors 31. Air under pressure is supplied to a trough 33 beneath the sensors so that the upward deflection of the strip gives a measure of its tension. The rams 23 are individually controlled in response to the tension measurements to control the roll pressure and provide a flat strip.

Title: Improvements in or relating to circuit arrangements for television receivers of the intercarrier type
IPC: H03J7/02
Filed: 1964-08-04
Abstract: 1,062,195. Automatic frequency control systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 4, 1964 [July 30, 1963], No. 31027/64. Heading H3A. In an intercarrier television receiver a first detector 5 derives the audio F.M. carrier (5À5 Mc/s.) from the I.F. input after amplification thereof at 1, 2, and a suppression filter 14 tuned to the audio-intercarrier (33À4 Mc/s.) produces as output the video signal, and since this output includes some audio intercarrier when the receiver local H.F. oscillator is incorrectly tuned, this spurious, intercarrier after detection at 15, is phase compared with the output from the first detector 5 to derive an A.F.C. voltage for the local oscillator. In a black and white system any detected intercarrier output of the second detector 15 is amplified by the video output tube 17 (or separately) and applied, over a circuit 19 tuned to the audio carrier frequency, to the phase comparator 16 also tuned to the same frequency (5À5 Mc/s.), the other comparator input being derived through transformer primary 26 from the anode circuit of the audio carrier amplifier 10. A ratio detector 11 demodulates the F.M. audio carrier. In a colour system, Fig. 5 (not shown), the suppression filter 14 and detector 15 are located in either the colour or the luminance signal channel, the two inputs to the phase comparator being derived as in Fig. 1. A ratio detector type of phase comparator is, however, used. The phase comparator 16 may be combined with the audio-frequency discriminator, Fig. 8 (not shown). Thus, the lead connecting the output of audio carrier amplifier (40) to the centre tap of the tuned secondary circuit of the discriminator (11) may include a coil coupled to an anode circuit of the video output tube 17 (Fig. 1) tuned to the audio carrier frequency. A D.C. output for A.F.C. is then derived as well as the audio output.
