Title: Oil cooler having automatic bi-metal thermostat controlled shutter
IPC: F01M5/00
Filed: 1944-12-28
Abstract: 603,638. Cooling radiators for motor vehicles. TRIGGS, W. W. (Garrett Corporation). Dec. 28, 1944, No. 26012. [Class 64(iii)] An oil cooler 10 comprises a casing 18, around which is a circumferential muff 19, having an oil inlet 15 and an oil outlet 16 which leads to a chamber 24 in the control device 13 which operates the shutters 12 to regulate the flow of air through the cooler. The oil enters by the inlet 15, some flowing through a port 21 into the cooler from which it leaves by outlet 16 to enter the chamber 24 and so out via a pipe 27. Normally there is no flow through the muff 19 which is closed by a valve 28. In the chamber 24 is a thermostat 40 comprising two bimetal helices 41 and 42 connected together at their right-hand ends, the lefthand end of the inner being fixed, whilst that of the outer is fixed to a cylindrical valve 48. Should the temperature of the oil in chamber 24 fall, the coils 41 and 42 will rotate to open the valve 48 to allow oil which is under pressure in a conduit 56 from the muff 19 to flow through a line 51 to a chamber 39 which connects with chamber 24 through a narrow passage 61. The pressure increase in the chamber 39 will force a piston 34 to the right to close shutters 12 through a link mechanism. Similarly, should the oil in the cooler congeal the increase of pressure in the muff 19 and conduit 56 will force a hollow valve piston 65 up to permit oil from conduit 56 to flow into chamber 39 as before, to close the shutters. This shutter-closing action due to increase in oil pressure in the cooler, overrides the normal operation of the shutters by the temperature of the oil emerging from the cooler in chamber 24, and also their operation by changes of viscosity in the oil in chamber 39, the rate of escape of which oil through passage 61 varies as its viscosity. Should oil in the cooler congeal, and valve 65 be opened as above described, the oil in the muff 19 forces the valve 28 at the exit end of the muff open, the warm oil flowing through the muff and hence decongealing that in the cooler. The thermostat 40 may be adjusted by means of a lever attached to the other side of the plate to which the inner helix is secured. Specification 575,425 is referred to.

Title: Improvements in or relating to electrical positioning systems
Inventor: VARRALL JOHN EUSTON
IPC: G05B19/33
Filed: 1965-06-21
Abstract: 1,105,784. Follow-up systems. AIRMEC Ltd. 20 Sept., 1966 [21 June, 1965], No. 26154/65. Heading G4H. A movable member is coupled to a plurality of switches e.g. through 10 : 1 reduction gears, a binary coded decimal input e.g. from a programme tape, representing a desired position of the member, actuates respective sets of relays A-D to earth a selected contact 1-9 of each of the switches and the potentials applied to the remaining contacts of each switch are such that the pick-off means comprising lead and lag brushes B1, B2 associated with each switch provides an error signal representing the distance of the pick-off from the selected contact so that by algebraically summing the various error signals with individualweighting proportional to their respective denominations, a total error signal representing the distance of the member from the desired position is obtained. The speed of the means positioning the member may be controlled in accordance with the magnitude of the total error signal. The intermediate denominational switches are each associated with a transformer TR which has 12 equally spaced taps -1 to 10, so that contacts on either side of the earthed contacts have potentials applied thereto which vary in equal steps and are of opposite phases. The highest denomination switch is associated with a transformer having 10 equally spaced taps. Switching of the lead and lag brushes B1, B2 of the next higher switch is controlled by a relay such as TB connected between the centre tap and the output of the associated switch. To avoid excessively accurate reference potentials and large transients when lead/lag change over occurs, a special arrangement is used when one of the intermediate digits of the desired position is 0 or 9. In the case of digit 0, a relay RX is energized to earth the 0 tap and supply a potential corresponding to -1 to the 9 contact of the associated switch. This has the effect of causing lead/lag change over on the next higher switch at the transition 8-9 rather than 9-0 to effectively advance the next higher switch by one digit, one digit of the lower switch earlier than normal, but the choice of potentials produces the same error signal. Similarly, in the case of a digit 9, the 0 switch contact is connected to the 10 tap by relays A, D and lead/lag change over occurs at the 1-0 transition rather than at 0-9. The lowest order switch corresponds to the two lowest denominations and comprises ten contacts and a set of interconnected vernier brushes as described in Specification 1,078,661. The relays A-D of the lowest denomination connect one of 10 taps of a transformer to a single lead, this providing the input to the relay decoding tree of the second lowest denomination, rather than earth as shown in Fig. 2. Meters such as Me are provided for read-out of actual position when balance has been attained.

Title: Control circuit
IPC: G05D23/24
Filed: 1960-07-28
Abstract: 907,082. Automatic systems for controlling temperature. CHEMSTRAND CORPORATION. July 28, 1960 [Aug. 14, 1959], No. 26232/60. Class 38 (4). A circuit which controls the temperature of a block for hot drawing nylon yarn comprises an A.C. bridge 11 of which one leg is formed by a thermistor 12 for sensing the temperature of the block. A relay 35 controls energization of a heater 53 and is connected in the plate circuit of a thyratron 21. The primary of winding 16 of a step-up transformer 15 is fed from the bridge 11 and a phase shifting circuit 19 connects the secondary of the transformer to the thyratron via a transistor amplifier 18. The circuit 19 is necessary to align precisely the signal applied to the grid and that applied between the plate and cathode of the thyratron. With the block and thermistor at the desired control temperature, the bridge legs 14 are adjusted for balance and no signal is developed across transformer primary winding 16. If the temperature falls below the control point, the amplified signal applied to the control grid of the thyratron is in phase with A.C. voltage applied between the plate and cathode of the thyratron, and the thyratron fires on every positive half-cycle of A.C. The relay 35 and heater 53 will therefore be energized and will remain so, during each negative half-cycle, due to a capacitor 36 which maintains the current through the relay. When the temperature rises above the control point, the signals applied to the thyratron grid and plate are in opposite phase and the heater 53 is not energized. It is stated the block may be maintained at the desired temperature to an accuracy of ¢ C.

The core may also contain an arc stabilizing material, e.g. potassium or titanium compound such as potassium oxalate. A.C. or D.C. of at least 50,000 amps. per square inch of electrode cross-section is used. An electrode for welding low alloy manganese steel has a mild steel sheath and a core of ferro-manganese. An electrode for welding austenitic manganese steel has a mild steel sheath cored with a mixture of 40 parts iron powder and 60 parts high carbon ferro-manganese. The electrode contact means may have a tubular extension for guiding the electrode either made of an insulating material or insulated from the contact means. Suitable materials for the guide are aluminous porcelain, zirconia, sillimanite, mullite, silicon nitride or heat-resisting alloys.
