Patent GB-1305132-A (GB)
IPC: B60T13/18
Filed: 1970-04-22
Abstract: 1305132 Power steering mechanism BENDIX CORP 22 April 1970 [16 May 1969] 19172/70 Heading B7H [Also in Division F2] An hydraulic braking system for a motor vehicle which braking system is integral with the steering system includes a flow control valve assembly 24 operable to connect a transmission driven secondary pump 18 to the braking system upon failure of an engine driven primary pump 16 which normally supplies the system; the flow control valve assembly 24 comprises a one-way spring-loaded check valve 54 which is opened by fluid flow from pump 16 through a conduit 34 and the fluid flow then passes through channels 55 to a restricted orifice 68 and thence through a passage 66 in a spool valve member 64 to a conduit 38 which leads to an hydraulic booster 12 of a tandem master cylinder 14 and thence via a conduit 40 to an hydraulic power steering gear 10. As the flow through the orifice 68 increases to a predetermined amount the valve member 64 is moved to cause end 114 of the member 64 to unlap a counterbore 108 and allow return of the fluid through a cavity 72 and passage 76 and a conduit 44 to a reservoir of the pumps 16, 18. When the vehicle is in motion fluid flow from pump 18 will enter the valve assembly 24 through a conduit 36 but with the pump 16 functioning to produce the predetermined flow, the flow from pump 18 is returned to conduit 44 via passages 104, 106, cavity 82, counterbore 110 (unlapped by movement of shoulder 112 on valve member 64), cavity 74 and passage 76. However if the pump 16 fails then fluid flow from pump 18 acts to open a one-way check valve 98 and fluid flow again passes via cavity 80 to the orifice 68 and thence to conduit 38. The combined braking and steering system which is stated to be of the open-centre type will therefore continue to function even if the pump 16 fails.

Title: Improvements in or relating to Customer-Operated Dispensing Systems
Inventor: DAVIES ANTHONY IVAN OLIVEIRA
IPC: G07F19/00
Filed: 1966-05-02
Abstract: 1,197,183. Banknote dispensers. SMITHS INDUSTRIES Ltd. 25 July, 1967 [2 May. 1966], No. 19319/66. Heading G4X. Apparatus adapted to control access to a dispensing apparatus, for example a banknote dispenser, comprises means for sensing information recorded on a token presented to the apparatus, manually operable switches for entering information into the apparatus, a comparator for the information sensed from the token and information entered by said switches, and access control means selectively operable by the comparator in dependence upon a predetermined relationship existing between said two sets of information. A banknote dispenser includes a card reader 11 having read switches 12 actuated according to a customer's number P1-P5, account number A1-A4, and branch number B1-B3 recorded on a token presented thereto. The card reader senses the numbers P1-P5, A1-A4, and B1-B3 in turn under the control of a timing unit 14, sequencing unit 15, and pulse-routing unit 13. The timing unit steps automatically from one stage to the next unless an inhibit pulse is applied at 18. In this case, the unit steps from stage II to III, IV to V, VI to VII, and VIII to IX only when a pulse is applied on line 17. The latter pulse is obtained on actuating a pushbutton 16 which sets a corresponding flip-flop 26. The output from the card reader is fed to a binary to decimal converter 23 actuating a printer 25 and supplying a re-set pulse to an appropriate flip-flop 26. If the number entered manually by a push button disagrees with the number P1-P4 sensed from the token, the output from converter 23 is applied to a flip-flop other than the one set by the push-button. An error detector 28 operated by the converter to sense the state of the flip-flops, controls printer 25 and banknote dispenser 29 on receiving a pulse on line 38. The printer records the numbers P1-P4, A1-A4 and B1-B3 in black or red, according to whether a signal is placed on line 39 or 40, to indicate acceptance or rejection of a token.

Title: Improvements in borehole clinometers
IPC: E21B47/022
Filed: 1933-07-10
Abstract: 422,701. Borehole clinometers. WILLIAMS, S., Windermere, Yenangyuang, Upper Burma. July 10, 1933, No. 19462. [Class 97 (ii)] A casing adapted to be lowered into a borehole and to give at the ground level an indication of the inclination of the borehole and the depth at which the measurement is made has a number of gyroscopically directed contacts disposed equidistantly about the axis of the casing just above the surface of some mercury or other electrically conducting liquid so that tilting of the liquid surface closes the circuits of one or more pilot lamps at the ground level and indicates the direction of inclination. As shown, the contacts 10 lie over the surface of mercury 7 in a cup-shaped receptacle at the bottom of the casing 5 and are mounted on a ring 9 fixed to a spindle 12 rotatable about the axis of the casing in ball bearings 15. The contacts are initially set with the aid of a magnetic compass and thereafter stabilized by electrically driven gyroscopes 13, 14. In order to measure the amount of inclination a number of copper discs 19 spaced by insulating discs 20 are fixed above a mercury surface 17 so that two or more discs 19 according to the inclination are electrically connected, causing part of a resistance (not shown) to be short-circuited. The lead 22 from this resistance, the leads 11 from the contacts 10, the leads to the motors driving the gyroscopes 13, 14, a lead from a contact 30 at the bottom of the casing 5, and the cable to which the casing 5 is attached are stranded together into a single cable wound on a spool at the ground level. A counter indicates the extent of cable unwound. When it is desired to make a measurement a plug is inserted into one end wall of the spool and connects the leads 11 to a series of pilot lamps arranged round a compass dial. A central pilot lamp is connected to the contact 30 and is illuminated when the casing 5 reaches the bottom of the borehole. A second plug is inserted in the other end wall of the spool and connects the lead 22 to an ammeter, adapted to indicate the amount of the inclination.

Title: Improved electric circuit breaker and latch structure
IPC: H01H71/50
Filed: 1959-06-08
Abstract: 921,420. Automatic circuit-breakers; camoperated switches. HEINEMANN ELECTRIC CO. June 8, 1959 [March 18, 1959], No. 19591/59. Class 38 (5). In an automatic circuit-breaker a force transmitting linkage between an operating member and a biased moving contact member comprises a pair of relatively pivotable links associated with a bowed spring. As shown, the links 73, 74 are normally retained by the bowed spring 71 in substantial alignment against a wall 90 along which the link and spring assembly can slide to transmit force from the operating handle cam 54 to the laminated contact spring 35 which is biased away from the fixed contact 30. The outer ends 76, 76<SP>1</SP> of the links 73, 74 retain the ends 85, 85<SP>1</SP> of the bowed spring 71 and are guided for straight-line movement in slots 77, 78 in a two-part casing having other slots and recesses for locating circuit-breaker parts and from which the wall 90 projects. On overload, a series electromagnet 37, 43 attracts an armature 45 which is pivoted at 47 and has a limb 49 which moves through a gap 91 in the wall 90 to engage the link 73 so as to move the spring 71 over-centre so that the links are no longer in force transmitting alignment and allow contact 35 to move away from the fixed contact 30. Since the end 76 of the link 73 is no longer urged into a notch in the cam handle 54, the latter is restored to the " off " position by a spring 64 mounted about its pivot 56. The spring 71 is unstable in its bowed upward position and acts to reset the links 73, 74 in substantial alignment.

Title: Multitrack magnetic tape recording
IPC: G11B5/027
Filed: 1974-05-03
Abstract: 1515283 Recording multi-track tapes BANDMASTER Ltd 6 May 1975 [3 May 1974] 19604/74 Heading G5R Each of the multiple longitudinal tracks on a magnetic tape carries a respective non-interrupted sound pattern, each pattern being formed by a sequence of groups and having the same number of said groups as all the other patterns all the groups of all the patterns having the same length as one another, and the start of each group of each pattern being located in its respective track in the same predetermined positional relationship with respect to the start of a corresponding group in the or each adjacent track. The groups of the various sound patterns may be the bars of music or rhythm patterns. The recording may be effected by recording a count-in audio signal followed by a calibration timing signal on a first track, then recording a music or rhythm pattern with the count-in signal on a second track while the calibration signal is being replayed so that the start of the pattern on the second track is at the same point lengthwise of the tape as the start of the timing signal with the bars of said pattern in sync. with the pulses of the timing signal. The third, fourth &c. tracks are then similarly recorded and then the first track is erased, and by using the count-in signal on one of the other tracks, a music or rhythm pattern is recorded on the first track so that the start of corresponding bars on all the tracks are on lines perpendicular to the tape edges. Alternatively all tracks can be recorded simultaneously, and a musician may record on the first track while listening to the tuning signal which is never recorded. The master tape so formed is edited by removing the count-in signals and cutting so that each track has an integral number of bars, the tape then being formed into an endless loop and copied on to commercial tape which is cut into lengths for endless tape cartridges. If tapes are required in which the starts of corresponding bars of the various tracks are staggered along the tape length, such staggering may be introduced at the copying stage or delays may be introduced into the master tape recording system. The various tracks may be recorded with different rhythms or in different keys, for example, to provide backing rhythms.
