Abstract: 1432961 Optical lenses CANON KK 25 June 1973 [23 June 1972] 30115/73 Heading G2J A positioning device for the lens components of an optical system (e.g. a zoom lens) comprises holders 80, 90 for holding rigidly lens components L 2 , L 3 ; operating means e.g. 206 to effect simul-  taneous movement of holders 80, 90 along the optical axis, guide means 101a, 102a, 122, 123 to control the movement and hence the relative positions of holders 80, 90 with respect to each other, and pre-settable adjusting means for adjusting the spacing between holders 80, 90 by small amounts compared with the total possible movement imparted by the operating means. The presettable adjusting means are pre-set during assembly to correct for errors in the construction of the system. In one arrangement, Fig.11, the pre-settable adjusting means comprise relatively axially displaceable camming rings 101, 102 for the lenses L 2  and L3 respectively. Ring 101 has slots 101b, 101c which reveal openings 102b, 102c in the other ring 102 so that rotation of tools 40, 41 which have eccentric projections 40a, 41a in the openings 102b, 102c causes axial or rotational movement respectively between the rings. This adjustment  may be made during or after manufacture. In another arrangement, Fig. 9, the camming rings are not relatively adjustable, but the holder 18 for lens 17 is slidable along a guide rail 25 by rotation of a screw 20 having an eccentric collar 19 which fits inside an aperture 3 in the camming ring 1. In a further arrangement Fig. 8 (not shown) one cam ring is slidable outside the other and is held in position by threaded locking rings engaging with the inner cam ring. Alternatively Fig. 7 (not shown) the cam rings may themselves be screw threaded to engage adjustably.  In a still further arrangement Fig. 13, one lens L 2  is moved by means of rack 204 and pinion 205, motion being transmitted to another lens L3 by a plate 210 having slots 210a, 210b receiving pins 209, 201a attached to each lens, the plate 210 being pivoted at pin 211. The definition adjustment is by means of a slotted plate 208 which holds the pin 209 of lens L 2 .

Abstract: 951,067. Sensing record cards. UPTIME CORPORATION. Sept. 3,1960, No. 30468/60. Heading G4M. In a sensing device for record cards having holes in rows and columns,there is a row of photocells 61 Fig. 6 over which the card is fed by rollers 18 which sense the rows of the card in succession, a series of photo-cells 64 spaced in the direction of motion of the card being covered in turn by the leading edge of the card to produce timing pulses corresponding to the index positions of the card columns. The signals from the photocells 64 are inverted to produce pulses which are used for gating out the signals from the photocells 61. To avoid having a large number of gates, the timing pulses are combined on a single line and applied to each of a row of gates equal in number to the number of columns. Cards are fed from an input hopper 26 by a friction roller which rotates on a movable spindle, a cam being provided repeatedly to bring the roller into engagement with the end card of the stack. A device normally preventing this movement is disabled, by operation of a solenoid, to allow card feeding to take place. As the cards pass through the sensing station lamps 59, Fig. 5, shine light through the holes in the card to energize the sensing photo-cells 61 and the timing photo-cells 64 are covered one by one by the leading edge of the card. The photocells 64 are mounted on an adjustable slide 57 whereby their position relative to the row of cells 61 can be corrected. After sensing the cards are delivered by a guide 95 to an output stack having a falling table 89 controlled by a spring 94.

Abstract: 744,344. Automatic control systems for electric arcs. FUSARC, Ltd. Nov. 4, 1953 [Nov. 4, 1952], No. 30485/53. Class 38 (4). Operation of a push button 12 energizes an A.C. motor field 5 and armature 6 from an A.C. source S through a transformer 7 and an autotransformer 11. The motor, operating through reduction gearing (not shown), slowly feeds a welding electrode 3 towards work 4. When contact occurs push button 12 is released and a switch 10 closed to energize a relay 9, contacts 8 of which close to supply welding current through a transformer 1 and a choke 2. Flow of welding current causes energization of a relay 22 through a rectifier 21 to open a contact 14 and close contacts 17, 20, 24. The alternating voltage between the electrode and the work is then applied in opposition to an alternating voltage obtained from S through a transformer 19 to motor armature 6 through a transformer 16. Thereafter the motor operates to maintain a predetermined arc voltage. Condenser 18 ensures optimum relative phasing of the motor armature and field supplies. Relay 22 may operate a further contact to initiate transverse movement of the electrode over the work. In a modification, relay 9 is dispensed with and welding current commences when the electrode makes contact with the work.

Abstract: 929,783. Valves. J. NICHOLSON, and NORSEN SYNDICATE Ltd. Sept. 8, 1959, No. 30684/59. Class 135. A valve for actuation by rotation of a hose reel consists of a body 1 for attachment at 15 to a fixed supply pipe and a valve casing 4 rotatable in the body and having a seating for a valve disc 19 which is slidably mounted on a stud 24 secured to a spindle 33 which has a square shank passing through a correspondingly shaped socket 37 so that it is axially slidable but non-rotatable relative to the body. The socket 37 is carried by radial arms leaving passages (not shown) for liquid. The casing 4, which is connected at its lower end 16 with the hose pipe and is thereby rotated when the hose reel is turned, is held against axial movement in the body by a nut 9 with packing 14. A flange 40 integral with the stem 33 has cut-away portions (not shown) at its periphery to permit the passage of liquid from the inlet to the outlet and is screw-threaded to coact with a screwthread 42 in the casing so that as the latter is turned the stem 33 together with the valve disc 19 is moved axially in the casing, the axial extent of the thread 42 being such that after the valve disc has been closed or opened, depending upon the direction of rotation of the casing, the threads on the flange 40 become disengaged from the thread 42 so that the casing may then turn freely without further actuation of the valve. To ensure that the threads are re-engaged on reversal of the direction of rotation of the casing springs 36, 47 are provided, the spring 36 being compressed by relative axial movement between the stud 24 and the valve disc 19 when the latter engages its seating and the spring 47 being compressed when the valve is open. The valve disc carries a leather washer 28 which is secured by a flanged ring 29 and a screwed cap 30 which also encloses the tapered head 27 of the stud 24.

Title: Improvements in and relating to frequency modulated transmitters
IPC: H03C3/06
Filed: 1945-11-16
Abstract: 631,450. Frequency modulation. GENERAL ELECTRIC CO., Ltd., and HELLER, D. M. Nov. 16, 1945, No. 30807. [Class 40 (v)] In a frequency-modulation transmitter of the kind in which a phase-modulating stage is followed by frequency-multipliers, the initial signal is raised in the frequency spectrum and is integrated before it is applied to the phasemodulating stage. Raising of the frequency is effected by mixing the initial signal with an auxiliary oscillation. of higher frequency than the upper limit of the signal, and by selecting one of the side-bands from the resultant, preferably the lower side-band. The selected side-band is integrated and used to phasemodulate a carrier which is then frequencymultiplied before transmission. Owing to the raised frequency of the input to the phase modulator, less frequency-multiplication is required to produce a desirable frequency swing in the outgoing carrier. At the receiver, the normal F.M. detector is followed by a heterodyne stage in which an auxiliary oscillation of the same frequency as that used at the transmitter is mixed with the detector output so as to reproduce the initial signal. The auxiliary oscillation may be transmitted as a frequencymodulation of the carrier.
