Title: Method of printing and apparatus therefor
IPC: G06K15/14
Filed: 1963-12-06
Abstract: 1,031,898. Printing processes. STANDARD TELEPHONES & CABLES Ltd. Dec. 6, 1963 [Dec. 13, 1962], No. 48260/63. Heading B6C. A method of printing comprises producing a latent magnetic image of the matter to be printed, applying said image to one side of a record blank on which the matter is to be printed, applying finely divided magnetic particles to the other side of the blank, whereby the particles collect on the blank at the magnetized areas of the latent image, and treating the blank to cause said particles to adhere thereto. In the machine shown, this method is effected by traversing a continuously moving endless band 15 of magnetizable material by four heads 20 mounted on a continuously rotating disc 16 and receiving signals, corresponding to the matter to be printed, from a wire via a brush 25 and commutator 24 which rotates with the disc. The band with the latent image thereon moves beneath a roller 13 where it contacts a continuously moving record blank in the form of a paper web 47. The undersurface of the latter at its line of contact with the belt 15 is immersed in magnetic ink 58 which may be of powder or liquid form. The now visual image is fixed to the web 47 by passage through co-operating rollers 49, 50, the latter being resiliently mounted. The belt is passed across an erasure device 60 after leaving the roller 13. The disc 16 is rotated by a motor 28 which also drives the belt drive roller 8 and the web drive roller 49 through suitable bevel gears, shafting and worm drives. Belt roller 9 is resiliently mounted through spring-loaded slidable bearings 10 in order to keep the upper layer, i.e. the latent image receiving surface, of the belt in a taut condition. One or both of the pressure rollers 49, 50 may be heated to aid the fixing of the image. The machine drive is so arranged that each head 20 traverses the belt 15 in a straight line normal to the direction of belt travel. In an alternative machine the disc is dispensed with, five or seven stationary heads being positioned across the belt, the movement thereof furnishing the horizontal sweep.

Abstract: 1,062,983. Regulating and charging I. C. engines. PERKINS ENGINES Ltd. Dec. 5, 1963 [Dec. 21, 1962], No.48346/62. Heading F1B. An I. C. engine pressure charging system comprises at least first and second turbine/compressor units 7, 8 and 4, 14 arranged so that exhaust gas passes through the turbine 8 to valve 11 so that variable quantities may be passed to the turbine 14. A first stage compressor 4 draws in air through an inlet filter 5 and passes it to second stage compressor 7 through duct 6, compressed air then being delivered to inlet manifold 2. Gases from the exhaust manifold 3 drive turbine 8 which in turn drives compressor 7 through a shaft 9. Exhaust gas flowing through duct 10 is apportioned by valve 11 into ducts 12 and 13A. In other embodiments the positions of the first and second stage compressors are reversed, the first stage compressor may be partially by-passed by a valve control and the second stage compressor may be partially or completely by-passed by the valve controls situated in a by-pass duct and in the second stage compressor inlet and outlet ducts. The control valves may be actuated conjointly with the engine throttle or in response to speed or pressure signals. Operation. Valve 11 is kept fully open to turbine 14 until 40% of maximum power is attained and is thereafter progressively closed to turbine 14 until maximum speed is reached. This gives a substantially constant H. P. delivery in the speed range between peak torque and maximum engine speed.

Filed: 1976-11-23
Abstract: 1511202 Interference suppression in radio receivers AUTOVOX SpA 23 Nov 1976 [25 Nov 1975] 48752/76 Headings H4R and H4L A circuit for the suppression of noise and "scratch" (arising during tuning, or from low level signals) in a stereo receiver comprises, connected in cascade between the demodulator and decoder, a pulse noise suppressor circuit 5, a scratch suppressor circuit 6 and a muting circuit 7, and includes a control circuit 13 responsive to a signal containing scratch and controlling the circuits 6 and 7. Normal signals input at 14 pass via a transistor Q 8  to an output 17. A low-Q resonant circuit 26 which acts as a high-pass filter rejects normal signals, but allows interference having frequency components above about 55 kHz to turn off Q 8  via Q 1 , Q 2  and Q 3 , the lost signal element being made up from a storage unit 24. An OR gate 31 ensures that either polarity of interference is effective to turn off Q 8 . Scratch noise of amplitude too low to affect 31 passes via a connection 18 to the control circuit 13 which amplifies and rectifies it, and delivers the output to circuits 6 and 7. Scratch suppressor circuit 6 is a low pass filter having a cut-off frequency which varies inversely with the scratch amplitude, so as to reject the decoder frequency when scratch is strong and thus cause the receiver to switch to mono; muting circuit 7 narrows the A.F. bandwidth as the scratch amplitude increases.

Abstract: 1,274,985. Antiskid devices. TOYOTA JIDOSHA KOGYO K.K., and NIPPONDENSO K.K. 15 Oct., 1970 [18 Oct., 1969], No. 49078/70. Heading F2F. An antiskid device comprises a lock detector consisting of a wheel speed responsive tachogenerator 50, a reference wheel speed voltage generator and a differential amplifier 108 which generates a signal passed to a three way electromagnetic valve 70 controlling a brake pressure modulator 90 when the reference wheel speed voltage is higher than the wheel speed voltage, a pressure difference detector 200 generating a signal when pressure in a wheel cylinder 20, Fig. 2 (not shown), equals that of a master cylinder (30) which is fed to a control circuit which switches the reference voltage generator from a first to a second predetermined rate after the generation of a signal from the differential amplifier. In normal operation hydraulic fluid passes to a wheel cylinder through passages 91a, 92 and 91b of modulator 90. When a signal is generated indicating wheel lock a piston 72a of electromagnetic valve 70 is moved by energization of coil 79 to engage a partition 78b which closes communication between a port 76a connected to engine vacuum at 80 and port 76b connected to a chamber D of modulator 90, and causes chamber D to be connected to atmosphere through port 76b and a further port 75. Chamber D is separated from a chamber E, permanently connected to vacuum, by means of a diaphragm 97 which is thereby forced rightwardly against the action of spring 98 carrying with it a rod 95b on which a piston 95 is disposed, the latter causing the volume of a chamber c connected through passage 91b to the wheel cylinder to expand and relieve the brake pressure at that wheel. Further movement of the diaphragm causes a valve 93 to be seated at 91d to close communication between the master and wheel cylinder. Under normal conditions a capacitor 101 is charged through diode 102 by a wheel speed voltage applied by D.C. generator 50. The reference speed voltage across capacitor 101 is lower than the wheel speed voltage by the forward voltage drop in diode 102 and no release signal is generated by differential amplifier 108. When the wheel deceleration exceeds the first rate of the reference speed capacitor 101 discharges at the same rate as the first deceleration rate. When the wheel speed voltage becomes less than the reference speed voltage across transistor 101 a positive release signal is generated by amplifier 108, which is power amplified at 109 and applied to the coil of valve 70 for relieving brake pressure.

Abstract: 1,153,190. Grinding. CARBORUNDUM CO. 2 Nov., 1966 [8 Nov., 1965], No. 49100/66. Heading B3D. Apparatus for mounting a cut-off tool 9 or the like comprises a drive member 19 mounted on a driving shaft 16, a driven member 21 having the tool 9 connected thereto, and means connecting the driven and drive members to permit limited oscillating movement of the driven member relative to the drive member. The drive member is connected by a screwthread or splines to the shaft 16 and has a hub portion 20 fitting with clearance into a recess 22 in the driven member to which the tool 9 is secured by a flange 24 and nut 25. Bolts 26 in the driven member 21 pass through sleeves 28, which are mounted in resilient bushes 29 in apertures 30 in the drive member, and engage a retainer ring 27. The sleeves substantially prevent relative axial movement between the drive and driven members but permit oscillating movement in a radial direction up to the limit determined by the clearance between the hub 20 and recess 22. The amount of oscillation may be controlled or prevented by insertion of one of a number of differently-sized plugs 31 into a bore in the driven member 21, the plugs engaging a thread in the shaft. The spindle is mounted in bearings in the end of an arm 6 which is movable about a pivot 5 by a handle so that the tool 9 driven by a belt from a motor 13 engages a workpiece W. A guard 10 has a slot 11 for permitting movement of the tool and an opening 12 for passage of the workpiece. In another arrangement for a surfacing operation, the spindle axis is vertical and the tool acts axially of the spindle.

Abstract: 1,034,556. Timed control of electric circuits. HUSQVARNA VAPENFABRIKS A. B. Dec. 7, 1964 [Dec.19, 1963], No. 49662/64. Heading G3T. A time switching device for electric apparatus, particularly micro-wave ovens, includes two or more holding circuits for a relay controlling the current supply to the apparatus, each circuit having a manual switch in series with a second switch, and a power driven timing cam or the like which is arranged to open each of the second switches momentarily, on the one hand after a time specific to the respective holding circuits, and on the other hand at moments corresponding in each holding circuit to the sum of the specific, individual time of that holding circuit plus the individual time or times of one or more of the remaining holding circuits. A choice of effective holding times is thereby afforded corresponding to the manner in which the manual switches are actuated. When input terminals 21, 22 are energized, current flows partly through the hot cathode type transmitter tube 5 and simultaneously energizes motor 4 through break contact 201 of relay 2. The motor, through cams corresponding to A to E in the timing diagram, Fig. 2, operates switches 10 to 14. After an interval corresponding to a sufficient heating of the tube, cam A closes switch 10 to energize a starting relay 2 so that it contacts 201, 202, and 203 move to positions wherein the motor is connected to switches 11 to 14, a manual switch 20 is connected to terminal 21 through contact 202, and relay 2 is held through contact 203. The motor stops and the cams are returned in known manner by a spring. If switch 20 and another manual switch 3 are now closed, a principal relay 1 is energized to close a contact 101 in the main circuit of tube 5 which starts operating. A predetermined time of operation varying from 20 secs to 5 minutes in steps of 20 secs, is obtainable by four press-button selector switches 15, 16, 17, 18. These may be marked with their characteristic time intervals and be of different colours, and are interconnected for automatic re-setting singly or in any combination. When set, the closing of switch 20 makes another circuit to terminal 21 through the manipulated switches 15-18, the corresponding switches 11-14 and contact 102 of relay 1 so energizing the motor again, and this circuit is maintained until the switch 11-14 in question is opened. Relay 1 then drops off and the cams are returned to home position. In a modification where no initial cathode heating is required members 2 and 14 are omitted, Fig. 3 (not shown), contacts 201-203 are replaced by permanent connections corresponding to the aperture positions of these contacts.
