Title: Improvements in or relating to temperature measuring indicating and/or controlling apparatus
Inventor: STEVENSON IAN WATT
IPC: G01K7/02
Filed: 1960-01-27
Abstract: 897,938. Electrical indicating systems. KELVIN & HUGHES Ltd. Dec. 30, 1960 [Jan. 27, 1960], No. 2933/60. Class 40 (1). A temperature indicating, measuring and/or controlling system and protection circuit comprises a thermocouple 1 (e.g. in a furnace) connected to a D.C. meter 2, a source 31 of alternating voltage in series with a resistor 33 across the meter leads, and a rectifier 32 having a certain threshold voltage below which it will not conduct also connected across the leads, whereby breakage of the thermocouple may be signalled. Resistor 33 is adjusted so that when thermocouple 1 is intact the voltage across rectifier 32, which is preferably a silicon diode, is below the threshold value. Meter 2 is preferably a moving coil instrument, the moment of inertia of the coil being sufficient to prevent A.C. from source 31 producing a deflection. If, however, the thermocouple breaks the increased forward voltage across the rectifier causes it to conduct, which results in meter 2 receiving a large D.C. signal, and leads to the operation of a safety switch or warning system.

Title: Improvements relating to compensating for amplitude variations of alternating voltage supplies
Inventor: SCANTLEBURY GORDON SYDNEY PENG
IPC: G05F1/52
Filed: 1947-02-01
Abstract: 650,771. Automatic control systems. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 1, 1947, No. 3115. [Classes 38 (ii) and 38 (iv)] The fluctuations in the voltage of an A.C. source supplying a load are compensated for by the automatic control of the resistance presented by a thermionic circuit in series with the source and load. A D.C. supply 6, Fig. 1, is derived from the A.C. source 1, through the transformer 2 and rectifier 4, and is stabilized by the transformer 3, the impedance of which is rendered resistive and adjusted automatically through the valves 7, 8. The valve 11 conducts to its anode and screen during alternate halfcycles due to the action of the suppressor, which is A.C. energized, the valve current is controlled by the control grid, in accordance with the D.C. output (or the A.C. supply voltage) and the grid voltages of 7, 8 are consequently adjusted through the transformer 12 so that the impedance reflected through 9 is resistive and maintains the voltage drop across the primary of transformer 2 substantially constant. In a second embodiment, Fig. 4, the valves 31, 32 which replace the valve 11 of Fig. 1, amplify the voltage at the winding 9 and apply it, with a phase reversal, to the control grids of valves 7, 8 and the resistive impedance of the primary of transformer 3 is a function of the amplification at 31, 32. The D.C. output 6 is applied, through a potentiometer 45, to the control grid of valve 44, which forms a cathode load to both valves 31, 32 the amplifications of which therefore vary in accordance with the D.C. voltage at 6. The compensation afforded by the system may be controlled by adjustment of the voltage fed from resistors 57, 58 to the control grid of valve 49 and further stabilization is effected through the positive feed-back path from the anodes of 31, 32 to the cathode of 44.

Title: Improvements in and relating to electric control systems for electric railways
IPC: B60M3/00
Filed: 1931-01-31
Abstract: 365,340. Control systems for electric railways. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Fitzgerald, A. S.; 1212, Union Street, Schenectady, New York, U.S.A.) Jan. 31, 1931, No. 3165. Convention date, Jan. 31, 1930. [Class 104 (iii).] In an electric railway system having a trolley circuit divided into sections 3 .. 6 supplied with current by a conductor 7 through substations 8, 9, 10, &c., the supply is controlled by switches 11, 12 in each section operated by battery current supplied through a switch 23, 24, 25. The switch 23 is controlled by carrier current supplied by a generator 13 on the vehicle 2 through the sections 3 .. 6 and tuned circuits 14 .. 19 which energize current receivers 20, 21, 22 in series with the switches 23, 24, 25. This carrier current.. is supplied only to the section through which the vehicle is passing and operates the switches such as 23, 24, coupled to the section by the appropriate circuits, such as 15, 16. Thus when the vehicle is in section 4 the switches 11, 12 of stations 8, 9 are operated to supply current to sections 3, 4, 5. When it moves on to section 5, carrier current is cut off from the circuit 15 and the switches 11., 12 of station 8 open, thus deenergizing section 3 ; at the same time carrier current reaches the circuit 17, 18 operating the switches 11, 12 of stations 9, 10, so that current is supplied to sections 4, 5, 6. Chokes &c. 26 .. 31 between the sections prevent the passage of carrier current from the section in which the car is moving to the adjacent sections. In another form, separate generators for each station supply the carrier current for the control of tumbler switches controlling the battery current to the switches 11, 12. The switches 23, 24, 25 may be controlled by two balanced impedance circuits 46, 47 supplied by the carrier current generator 33, the former being connected to a trolly section through a condenser 43, the latter to a dummy circuit 38. The grid of a thermionic device 48 is connected to the circuit 47, the filament to the circuit 46, and the anode to the switch ruling 49 in series with a battery &c. relay 50. Normally the circuits 46, 47 are so balanced that the grid potential is insufficient to operate the relay 49, but when the car enters the section, the balance is upset, and the relay is operated to close the switch. In another form, the switch 53 is controlled by two rectifier bridges 51, 52 supplied by the generator 33, the bridge 51' being connected to the trolly section through a condenser, while the bridge 52 is connected to a dummy circuit 38. The two parts 55, 59 of the balanced switch relay are connected across the bridges. When a car enters the section, the balance is upset and the switch is closed.

Abstract: 1342548 Cushioning of hydraulic jacks CATERPILLAR TRACTOR CO 24 Jan 1972 [29 March 1971] 3310/72 Heading F1D An hydraulic jack 10 comprises a cylinder 36 in which reciprocates a piston 44 and rod 46, a sleeve 50 being mounted on the rod for entry in to a cylindrical bore 48 in the cylinder head, the sleeve being mounted on the rod by an annular seal 55 alone. The sleeve 50 has stepped portions 60, 62 to provide an increasing restriction between the sleeve and bore 48 as the former enters the latter, thus cushioning the end of the piston stroke. The seal 55 has a U-shaped cross-section to define a lip which contacts the rod to prevent flow from chamber 42 to port 32 when the sleeve 50 enters bore 48. However, reverse flow from port 32 to chamber 42 moves the lip away from rod 46 to permit flow to move the piston away from the cylinder end, Fig.6.

Filed: 1941-03-12
Abstract: 548,529. Moulding by extrusion. LOWE CORPORATION, J. March 12,1941, No. 3372. Convention date, Oct. 2, 1940. [Class 87 (ii)] Batter contained in a hopper 21 open at the top to the atmosphere is sucked through an extrusion die 23 by vacuum in a chamber 24 surrounding the die outlet. The extruded batter is shaped by the lower end of the die and by a disc 38 removably fixed in the die into annular formations 107, which are then cut off by the descent of a cutting sleeve 25 telescopically mounted on the die. The annular formations (ring doughnuts) then fall into a doughnut frying machine having doughnut conveying mechanism. The base of the vacuum chamber 24 consists of two slidable plates 26 which, before the cutting operation has been completed, have been moved outwards to-the position shown in Fig. 8, to allow the annular formations to drop through the chamber 24. The horizontal reciprocation of the plates 26 and the vertical reciprocation of the cutting sleeve 25 are both effected by vertical reciprocation of a rod 61 which, via a lever 59 and clutch 95, 96. rocks a shaft 58 on which is keyed a bell-crank lever 56, one arm of which operates the left-hand plate 26 and the other arm of which, via one arm of a second bell crank lever 53 rocks a shaft 54. The other arm of lever 53 operates the righthand plate 26. Oscillation of the shaft 54 is transmitted to the cutting sleeve 25 by a clutch 80, 81 and a freely mounted sleeve 84 having forks 52 carrying pins which engage an annular groove 46 in the cutting sleeve ; the connection between the clutch and the sleeve 84 includes a screw adjustment 85, 86 which regulates the stroke of the cutting sleeve. The rod 61 is reciprocated by cam means from an electric motor which also drives a vacuum pump which, via pipe 35, continuously exhausts air from the chamber 24.
