Title: Improvements in or relating to sizing controls on grinding machines
IPC: B24B47/20
Filed: 1957-11-25
Abstract: 850,023. Grinding. NEWALL ENGINEERING CO. Ltd., and TEMPLE, W. K. Nov. 25, 1958 [Nov. 25, 1957], No. 36726/57. Class 60. A grinding machine comprises in combination, means for feeding grinding wheel and work together, sensing apparatus comprising a wear-resistant feeler to engage the grinding wheel as a result of feed movement sufficient to grind the work to a predetermined size, an electrical piek-up connected to the feeler, an electrical circuit connected to the pick-up which includes means for electronic amplification of vibratory pick-up current resultant from engagement and a signal or relay operated by the amplified current. If the machine is handcontrolled, amplified current could operate an audible signal such as a buzzer to cause the operator to stop the feed, take note of the point reached and separate the grinding wheel and work. Alternatively the amplified current will operate a relay controlling drive mechanism to retract the grinding wheel. The amplified current may serve to memorise and establish the feed for subsequent operations, and in cases where the wear of the grinding wheel is slow, this permits of so mounting the sensing apparatus that it can be swung out of the way during operations on a series of workpieces and then brought into action prior to another series. The grinding wheel 13 is carried by a slide 12 mounted on the bed 11. The workpiece 18 is carried by a table 15 mounted on guideway 14 on the bed. A cross-slide 17 on table 15 carries an upstanding hinged bracket 19 with a forwardly projecting portion 20 to which is secured a slightly flexible cantilever bar 22 provided at its lower end with a smooth-faced diamond 23. Connected to the cantilever arm is the contact member 34 of a pick-up unit 24 which may be a piezo-electric crystal or of moving iron or moving coil type. The pick-up is electrically connected to an amplifier 27 connected to a relay 28 controlling the automatic feed device 31 of the grinding wheel slide 12. The relay may, for example, control an electro-hydraulic feed valve at 31 if the feed is hydraulically operated or it may control an electric motor at 31 if the feed is motor operated. The circuit may be tuned so that it is receptive only to a certain band of frequencies including the resonant frequency of the cantilever arm, and may include filter circuits to reject unwanted frequencies due to general machine vibrations. The diamond 23 is set at the position which corresponds to the desired termination of the grinding wheel feed.

Abstract: 1,212,785. Printing-surfaces. REICHHOLD  CHEMICALS Inc. 1 Aug., 1968, No. 36759/68. Addition to 1,205,978. Heading B6C. ' A printing plate is made by placing a matrix  to be cast from on an inclined surface, applying a liquid thermosetting resin 17 to the face of the matrix adjacent its upper edge and allowing it to flow under gravity over the face of the  matrix towards its lower edge, meanwhile progressively confining, by lowering of platen 19, it at a rate not exceeding the rate of advance of the leading edge 17a of the resin. Platen 19 may be lowered quickly until it is almost in contact with the resin, then be lowered at a decreasing rate under hydraulic control from cylinder 75 to correspond with slowing of edge 17a as the resin spreads. Both platen 19 and the support on whose face the matrix is supported may act as heat-sinks for heat produced exothermically by the resin, as may top member 18, and they may be heated to a temperature below the peak temperature of the resin before casting begins. Both the platen 19 and the support for the matrix may be of 3 inch mild steel. Curing of the resin continues after platen 19 has been fully lowered and the resin completely confined. The resin used may be a polyester resin.

Title: Payout drive assembly and circuit for coin change dispensing apparatus
Inventor: BAYHA JACK ELLIOTT
IPC: G07D1/02
Filed: 1966-08-18
Abstract: 1,145,508. Change dispensing apparatus. TRANSMARINE CORP. 18 Aug., 1966, No. 37047/66. Heading G4X. A change dispensing apparatus comprises a magazine containing vertical stacks of coins and a slide bar 64 movable beneath the magazine and a spaced base-plate for dispensing the coins, the slide bar being driven by a motor 50 through a rack-and-pinion drive. A rack 32 is provided each side of the magazine and carries a pin 32b engaging the slide bar. The latter may be reciprocated between the right- and lefthand sides of the magazine, as seen in Fig. 3, to dispense coins 62 from the columns on one or both sides of the magazine into a common shoot 18. Each rack carries a lug engaging a switch 124 or 126, Fig. 5, at the extreme ends of its movement to move the switches to the positions 138 or 140. The switches 124 and 126 return to the positions 136 and 142 on being released. In operation, a 25 or 50 cent piece is inserted to momentarily close switch 128 or 130, respectively. Closure of switch 128 operates solenoid 108 moving over switch 116. This energizes solenoid 112 through path 136, 140 or 142, 138 to change over switch 120 controlling the direction of rotation of motor 122 and completes the circuit for the motor. As the racks move from one extreme position, the switch 124 or 126 returns to its normal position 136 or 142. When the racks reach the other extreme position the switch 124 or 126 is operated to break the supply circuit of the motor. Thus the slide bar completes one stroke to dispense coins from only one side of the magazine. Closure of switch 130 operates solenoid 112 to change over switch 120. The motor is initially energized through 138 or 140 and then through 132 or 134 when the switch 124 or 126 is released. When the racks reach the other extreme position the switch 126 or 124 is operated to energize solenoid 112 and reverse the motor. Operation of the motor continues until the rack returns to its initial position operating switch 124 or 126 to interrupt the power supply to the motor. In this case the slide bar completes two strokes to dispense coins from both sides of the magazine. Insertion of a coin operates solenoid 110 to open contacts 118. A solenoid 114 is de-energized to block insertion of further coins while the apparatus in in operation. If the coins in the magazine fall below a predetermined level a switch 106 is opened to de-energize the solenoid 114. Modifications to the circuit are described, whereby the apparatus may be used with only one coin denomination, Figs. 6 and 7 (not shown).

Abstract: 1511278 Neutron well-logging TEXACO DEVELOPMENT CORP 12 Sept 1975 [12 Dec 1974(<SP>3</SP>)] 37532/75 Heading G1A [Also in Division G4] In neutron well-logging, the measured 7-ray spectrum of the earth formation surrounding the borehole is compared with a composite weighted mixture of standard 7-ray spectra of substances postulated to exist in the formation, to derive the relative concentrations of elements in the formation; and these values are further combined with a function of the macroscopic thermal-neutron capture cross-section of the formation to derive its primary parameters. A pulsed fast neutron source 9, 8 (e.g. a D-T accelerator) irradiates a well-casing 4 and surrounding earth formations 3. γ-rays resulting from thermal-neutron capture, detected by a scintillatorphoto-multiplier 12, 11, provide energy-responsive pulses to gates 21a, 21b, 21c, which gate the pulses during three periods following each neutron pulse, the last period containing substantially only background radiation. Pulses thus sorted are applied to a #-computer 23 for calculating the macroscopic thermal-neutron capture cross-section for the formation, and to a pulse-height analyzer 25 for separating the γ-ray energy levels. The measured spectrum formed by the analyzer 25, and standard spectra, stored in a source 30, of known substances which might exist in the formation, are fed to a comparison computer 42 which, by least-squares estimation, finds the relative concentrations of those substances which best fit the measured spectrum. This information, combined in a parameter computer 46 with information from the #-computer 23, yields the quantities of the substances present, for application to a recorder 50.

Title: Apparatus for recording blood pressure
Inventor: FOLLETT DOUGLAS HAROLD
IPC: A61B5/022
Filed: 1961-10-19
Abstract: 955,011. Sphygmographs. UNITED BRISTOL HOSPITALS. Sept. 17, 1962 [Oct. 19, 1961], No. 37573/61. Heading ASK. A blood pressure measuring apparatus has means for recording the pressure at predetermined time intervals and this is achieved by a timing switch which, at each closure, switches on a pump to charge an air reservoir, the pressure in which is then allowed to fall slowly to make the desired record. The essential features of the equipment, as shown in Fig. 1, comprise a pump 10, driven by a motor 12, drawing air through a filter 14 and passing it through a magnetically actuated valve 18 to a manifold 20 and reservoir chamber 22. A regulator 26 allows a predetermined rate of leak and a pressure actuated valve 28 is fitted to cut off the equipment in the event of an excessive pressure being reached. The manifold may be exhausted through a second electrically actuated valve 30 and a pipe 34 is provided for connection to an inflatable cuff. The arrangement of the control circuits is shown in Fig. 2, wherein a mains supply is connected to terminals 36 and a 30-volt supply across terminal Z and earth. The timing motor 40 is connected directly across the mains and runs continuously, thereby closing contacts 42 at regular intervals. This energizes relay F which, in turn, energizes relays A and B and passes current to the pen recorder motor 64, to the valve solenoid V1, to open valve 18, to solenoid V2, to close valve 30, and to the pump motor 12. As the pressure rises, a mercury column completes a circuit through a contact marked by selector switch 50 to relay D but this has no effect. However, as the pressure rises further to energize relay E, at the pressure marked by switch 48, contacts E1 change over to stop the pump motor and close inlet valve 18. The pressure now drops slowly through the leak valve and pulse sounds are recorded by the pen. These are received by a microphone on the arm, the output from the microphone being filtered to give a response only to sounds within the audible range and thus to give a sharp cut-off when the diastolic pressure is reached. Consequently the pen records pulses only between systolic and diastolic pressures, but superimposed on these is a series of pulses representing pressure derived from the successive breaking of circuits by the mercury column as it falls. When the pressure falls below the value marked by selector switch 50, relay D is released so as to break the main circuit and release relay B. Consequently the circuits return to normal and exhaust valve solenoid V2 is deenergized to open the outlet from the air chamber. The apparatus also includes a thermal relay 54 which, by short-circuiting relay C and so breaking the main supply circuit, stops the functioning of the equipment if a test has not been completed within a predetermined time. In case of emergency the relay C may also be short-circuited, to stop the equipment, by a remote switch connected to a jack socket 56.
