Title: Improvements relating to temperature control for a compartmental vehicle
Inventor: ORAM GEOFFREY CHARLES
IPC: G05D23/19
Filed: 1961-12-22
Abstract: 947,232. Automatic temperature-control systems. J. STONE & CO. (DEPTFORD) Ltd. Nov. 30,1962 [Dec. 22, 1961], No. 46030/61. Heading G3R. In a heating system for a vehicle divided into separate compartments generally similar to that of Specification 827,774, the output from a main temperature-sensing circuit is combined with the output of a modulator in which an oscillatory voltage is modulated by a signal voltage proportional to the total heating or cooling current, or the difference between these currents, taken by the compartments, the modification of the main circuit output thus produced having the effect of altering the setting of the temperature-sensing circuit. Fig. 1 shows an arrangement in which the output terminals 9 of a Wheatstone-bridge 1, having a temperature sensing resistor 6 and being fed from a conventional transistor oscillator 2, are connected in parallel with the output of a diodebridge modulator 12 supplied with a reference voltage from the oscillator 2 and with a D.C. signal from a transformer-rectifier unit 16 whose primary winding 19 carries the total current drawn by the heaters in the various compartments. The modulator 12 includes a correcting network 23 to compensate for phase lag in the transformers 14, 15 and to make the signal applied to terminals 9 more sinusoidal. If desired this signal may be applied in series with the bridge output. The terminals 10 from the oscillator transformer 5 may supply a reference signal to a phase-detecting, step-discriminating network generally similar to that of Specification 902,896. If direct current is used to supply the compartment heaters the unit 16 is dispensed with and the signal is obtained from a diverter resistance in the heater supply circuit. Other modifications comprise: (1) operating the bridge 1 with direct current and the compartment heaters with alternating current, for which oscillator 2 is not required and the modulator 12 is supplied with an alternating current signal voltage proportional to the heater current, the centre taps of its transformers 14, 15 being connected to the bridge 1, and (2) the use of a modulator comprising transformers, transistors and a potentiometer and having a D.C. supply, a D.C. signal and an A.C. reference voltage, Fig. 2 (not shown). The circuit of Fig. 1 may be used with Peltier units arranged to heat or cool the compartments in a manner generally similar to that of Specification 947,231, the difference between the current supplied to the "heating" units and that to the "cooling" units determining the polarity and value of the D.C. signal supplied to the modulator 12. A typical arrangement of Peltier units is described, Fig. 3 (not shown). In the above arrangements a thermocouple temperature-sensing circuit may be used.

Abstract: 1,010,798. Magnetic storage arrays. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 7, 1962, No. 46379/62. Heading H3B. A magnetic storage array is formed by depositing, on a screen formed by conductors 1 and 2, magnetic material to form storage arrays 5. As shown in Fig. 1 the woven screen is completely covered with magnetic material drive conductors 3 and 4 passing through alternate columns and rows of meshes. As shown in Fig. 3 the magnetic material may be deposited to form separate cores 5. The conductors of the screen are preferably joined at each crossing point by rolling, soldering or plating before depositing the magnetic material which may be permalloy in the range 82% Ni to 18% Fe to 50% Ni to 50% Fe. The percentages of Ni in this range specifically mentioned are 82%, 79%, 65%, 61% and 50%. Fig. 5 shows a " basket weave " used to form circular cores and Fig. 6 shows the construction of a transfluxor which has two arms of half the cross-section of the others. Inhibit and separate sense conductors may also be included in the array (Fig. 7, not shown). If the insulated sense wires are included in the screen before-depositing the magnetic material and heat treatment of the screen is necessary the sense wires may have a thin film of nickel or cobalt phosphide deposited thereon and may have asbestos fibres wrapped thereon. Alternatively the wires may be threaded through fine quartz or may have a ceramic coating deposited thereon. The magnetic material is preferably deposited electrolytically and a method of producing uniform current density is described in the Specification and in Specification 1,010,799. The screen may be gold-plated before the deposition. After deposition the screen may be heated to anneal the magnetic material and if elements resembling thin fibres are required the cooling may be carried out in a magnetic field produced by currents in the sense conductors. The screen serves to conduct heat away from the cores and may be connected to a heat sink.

Abstract: 1,023,110. Discharging containers from below; screw conveyers. BUTLER MANUFACTURING CO. Nov. 19, 1964 [June 9, 1964], No. 47182/64. Headings B8A and B8E. Apparatus for discharging a circular container from below comprises a sweep auger 25 and two parallel discharge augers 26, in a partially covered rectangular recess in the floor 22, the pitch of which increases on the discharge side of the centre and again under the covered part of the recess. The necessary drives are provided from a single motor in a housing H which may drive the augers 26 alone or in conjunction with the sweep auger 25 with or without a drive to rotate it about a central pivot. The auger 25 may also be rotated manually from outside the container while it remains in a fixed position in the container. The sweep auger 25 is mounted in a housing 75, Fig. 9, extending between the augers 26 at the centre of the container and is driven from a drive shaft 64 through gear-boxes 85, 73 from a shaft 64 extending from the housing H. A hub extension 80 of the housing H is supported on a bearing surface 85 and extends through the recess 23 and is provided with a gear 83 by which the housing and auger are rotated within the container. The drive shaft 64 is connected through a clutch to the motor so that the augers 26 may be driven alone and two different drive speeds for the shaft 64 may be selected. The drive to the gear 83 to rotate the housing is from a crank 43, Fig. 12, on a driven shaft 39, a rod 103 and a crank 100a which through a one-way clutch 100 produces counterclockwise rotation of a shaft 92 having a chain drive connection to the gear 83. Return clockwise rotation of the shaft 92 is prevented while a gear 97 of a further one-way clutch engages a fixed rack 108 but this can be disconnected by operating a hand wheel 115. If the auger 25 becomes jammed while the drive is engaged a spring 107 allows continued oscillation of the crank 43 while the drive remains ineffective. If the drive of the shaft 64 is inadequate to rotate the auger 25 about its own axis it may be unjammed by manual turning by connection to a support assembly 116, Fig. 8. The shaft 123 of the auger is connected to the splined end 122a of a shaft 122 extending through a sleeve 117 and the auger may be turned by turning the head 122b of the shaft 122.

Abstract: 481,127. Cash registers. NATIONAL CASH REGISTER CO. Sept. 7, 1936, No. 24357. Convention date, Sept. 7, 1935. [Class 106 (i)] In a cash register or similar accounting- machine having differential mechanism associated with the overflow wheels of the totalizer, which differential mechanism is controlled in adding operations by keys to print and/or indicate non-additive data and in total-taking and sub-total-taking operations is controlled by the overflow wheels to set up the total, the totalizer actuator for each overflow denomination is normally coupled to its associated differential arm, but becomes uncoupled therefrom in adding operations. The invention is described as applied to a machine of the kind forming the subject-matter of Specification 8119/15, [Class 106 (i)], and consists in that the usual differential devices that, in total-taking operations, serve to set the type-wheels and indicators under the control of the overflow pinions of the totalizers, now serve, in adding operations, to set the type-wheels and indicators under the control of banks of keys for non-additive data. For this purpose the usual actuator 88 is connected to the usual differential arm 50 by a latch 93 that is pivoted by a stud 200 to the actuator and takes over a pin 94 on the arm. In total-taking operations, the actuator is rigid with the arm and sets the latter under the control of the associated overflow pinion 92 of the selected totalizer in usual manner. In adding operations, however, the latch 93 is disabled by the engagement of its stud 125 with a hooked arm 124 after one step of movement. Thus, while the differential arm is set under the control of the depressed key, the actuator is restrained and thereby prevented from adding the amount into the overflow wheel of the engaged totalizer or totalizers, but due to its step of movement is still capable of effecting transfer in usual manner. A spring- urged arm 150 bears beneath the stud 125 to hold the unlatched actuator against counterclockwise movement in operations in which transfer occurs to the overflow pinion of the selected totalizer of all three lines simultaneously. The hooked arm 124 is controlled by the usual shaft 110 that is rocked in total-taking operations, the connections including toothed sectors 117, 118, cam slot 120, stud 121, arm 122 and shaft 123. Specification 199,046, [Class 106 (i)], also is referred to.
