Title: Recording transducer selection limiter
IPC: G06K15/06
Filed: 1970-01-21
Abstract: 1291698 Line printer control systems RCA CORPORATION 21 Jan 1970 [28 Jan 1969] 2907/70 Heading G4H A line printer comprises N print hammers 18 positioned to record a line of characters, gates 66À1-66ÀN coupled to the hammer solenoids 54À1-54ÀN for selectively energizing the hammers, a shift register 94 responsive to the selection of a hammer for storing an indication that a particular hammer was selected and a gate 86 responsive to the stored indication to prevent the reselection of that particular hammer during further recording in the same line. Data in the form of binary characters corresponding to the characters to be printed on a line are fed from a computer 22 to a bank of shift registers 20 connected as a recirculating memory. A print drum 10 having M rows and N columns of characters is rotated on a shaft 12 to which a timing disc having M slots is attached. A photo-cell 32, co-operating with a light source 30, sends pulses to a counter 36 the output of which is the binary code of the drum character which is in the printing position. When the two inputs to a comparator 38 are identical, a signal is supplied to the gate 86 of a control logic circuit 40 (Fig. 2). The output of the gate 86 enables that gate 66À1-66ÀN which receives on its other input a signal from a counter 60. The output of the gate 86 is also connected via an " OR " gate 96 to the recirculating shift register 94 so that a binary " 1 "is entered in this register, the output of which is inverted and fed to the gate 86. Thus, if during a first print cycle a particular hammer has been actuated to print a character it cannot be re-actuated during a subsequent cycle to overprint a different character since a binary " 1 " output will be supplied at this instance by the register 94 and is inverted to inhibit the gate 86. A crystal controlled oscillator 78 generates sets of four pulses TPA-TPD as successive characters in a row reach the printing position, these pulses being applied to the circuit 40 to synchronize the system.

Title: Electrical signal storage apparatus
Inventor: NEWMAN EDWARD ARTHUR
IPC: G11B20/14
Filed: 1953-02-04
Abstract: 743,416. Electric digital data storage apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 29, 1954 [Feb. 4, 1953], No. 3141/53. Class 106 (1). A serial mode digit signal store comprises a first generator 37 of timing pulses at intervals of a given digit period, an input coincidence gate G3, G4 controlled by the timing pulses, means T1 &c. for applying to the input coincidence gate a train of digit signals in coalesced form and in step with a second generator 20 of pulses having the same repetition frequency as the first timing pulses but which may vary up to one digit period relatively in phase, whereby a signal output is produced in receipt of each first timing pulse which is in accordance with the nature of the digit signal then being received, means for writing the output of the input coincidence gate into the store during an inter-digit period by a change of electrical value, and means controlled by the first timing pulses for reading out stored digit signals in coalesced form and applying them to an output coincidence gate controlled by the second pulse generator 20. High-speed digit signals circulating round a loop 11 containing a delay line DL7 are applied to a gate Gl and, in complementary form to a gate G2 these gates being controlled by lower-frequency clock pulses to pass every ninth signal. A trigger T1, controlled by the outputs of the gates G1, G2 supplies coalesced data signals (Fig. 2d, not shown) to gates G3, G4 which are controlled by clock pulses derived from a track on a rotating magnetic drum 25. Signals passed on through the gates are converted to another form by a second trigger T2 (Fig. 2l, not shown). Track-derived clock pulses are passed through a 4¢-digit delay 38 and cause changes in the condition of the trigger T2; in one sense if the digit signal from the trigger T1 represents a binary " one," and in the opposite sense if the signal represents a binary " zero ". This output is applied through a gate G5 controlled by a transfer timer 21 to a write head in an assembly 23 which lays down a corresponding magnetization pattern on the drum 25. These patterns are picked up by read heads in an assembly 24, the position of which, relative to the write heads, may be adjusted to offset phase advance of the signals. The output (Fig. 2m, not shown) from the magnetic read unit RU is applied to a gate G6, and its complement is applied to a gate G7, these signals, under the control of the trackderived clock pulses, setting a third trigger T3 whose output consists of a coalesced waveform (Fig. 2r, not shown) equivalent to that originally developed by the trigger T1 (Fig. 2d, not shown). This waveform serves to gate clock pulses from the generator 20 into the highspeed memory loop 11 when signalled by a read transfer timer 22, which at the same time blocks corresponding data pulses from the delay line DL7 appearing at a gate 17. Specifications 717,114 and 732,221 are referred to. Reference has been directed by the Comptroller to Specification 707,634.

Title: Improvements in or relating to hot and cold water mixing taps
Inventor: COOPER FRANCIS CYRIL
IPC: F16K27/04
Filed: 1958-01-31
Abstract: 862,926. Valves. WOODROUSE & CO. Ltd. Jan. 21, 1959 [Jan. 31, 1058], No. 3234/58. Class 135. The body 1 of a manually-operated mixing- valve incorporates a central bore 5 connected to the hot-water supply that opens into an offset bore 20 which leads to a coaxial bore 3 of larger diameter and the upper end of which co-operates with a main closure-member 17 that carries a depending piston-member 16 embodying two reduced portions 15, 19, each of the latter being provided with a cross-bore 22, 23, respectively, interconnected by a passage 21 coaxial with the member 16. Cold water is admitted to the upper part of the bore 3 from an inlet 9 via annular passages 11, 12 and axial passages 13, 14. Initial unseating of the closure member 17 upon rotation of a handle 32 enables cold water only to pass from the bore 3 to an outlet 18 ; further lifting of the valve 17 starts to withdraw the portion 19 from bore 20 and hot water flows from the bore 5 to the outlet 18 via cross-bore 23, passage 21 and cross-bore 22. Continued lifting of the valve 17 increases the flow of hot water and gradually shuts off the cold water as the member 16 covers the end of the passage 4 where it enters the bore 3. The outlet 18 leads to a restrictor plate 27 in series with a rose 26. The valve 17 carries an " O "-ring 29 which grips the upper end of the portion 15 when the valve 17 is open and is compressed on to a chamfered seat at the top of the bore 3 when the valve is closed. The handle 32 operates the valve 17 by a spindle 33 having a quick-pitch thread such that one rotation moves the valve 17 from the open to the closed position; lugs may be provided to limit the rotation of the handle 32 and the latter may be fixed to the spindle 33 by a set-screw and splines, not shown. In a modification, the valve provides separate outlets 18 for the hot and cold water, which outlets are connected by separate pipes to the rose 26, the hot water pipe being inside the coldwater pipe and the rose having two sets of holes, each set corresponding with one of the pipes. The portion 15 is arranged above the closuremember 17.

Abstract: 547,745. Rectifying. GENERAL ELECTRIC CO., Ltd., and THOMPSON, W. G. March 14, 1941, No. 3538. [Class 38 (ii)] [Also in Group XXXVII] A reverse-current relay comprises a polarized contact-carrying armature 21 mounted in a gap 16 in a nearly closed magnetic circuit 17, 18 energized by the operating current coil 14. The armature is mounted on a part magnetized by a polarizing winding 15 and when the current in the coil 14 reverses the contact 22 on the armature engages a fixed contact 23. The relay may be used in a protective system .wherein a vapour arc rectifier S supplies a load 12, such as a trolley bus motor, capable of regenerating power which cannot be absorbed by the rectifier, the relay serving through the intermediary of valves and other relays to connect a resistance 60 across the lines 10, 11. When regeneration occurs, the reverse current through the coil 14 closes the contacts 22, 23 which raises the potential of the grid 30 of a valve 31 so that this becomes conductive and allows pulsating current from the motor to pass through a transformer 33, the secondary of which is connected to an ignition electrode 46 of a valve 40 which then becomes conducting whereupon a normally-energized coil 52 is short circuited and contacts 53 closed to insert resistance 60 across the lines 10, 11. When regeneration ceases, current through a relay 78 will cause the operation of a relay 75 to short circuit the valve 40 and of a time-element relay 72 to bring the system into readiness for further protection.
