Title: Pressure Proportioning Valve for Hydraulic Brake Systems
IPC: B60T11/34
Filed: 1967-03-07
Abstract: 1,159,876. Brake pressure proportioning valves; valves. KELSEY-HAYES CO. 7 March, 1967 [7 March, 1966], No. 10727/67. Headings F2F and F2V. A vehicular hydraulic brake pressure proportioning valve comprises a chamber 36, Fig. 2, providing communication between an inlet 28 and an outlet 32, an annular elastomeric valve member 84 co-operable with the valve head 66 of a pressure-responsive member 54 to restrict flow between the inlet and the outlet during a predetermined range of increasing fluid pressure at the outlet, the valve head 66 being slidable within the valve member to relieve pressure at the outlet upon a subsequent inlet pressure reduction. A pedal-operated master cylinder (10), Fig. 1 (not shown) supplies pressure fluid to front-wheel brake cylinders (18) and via the pressure proportioning valve (20) to the rear wheel brake cylinders (24). When the brake pedal is depressed pressure fluid passes from inlet 28 via passage 34, chamber 36 through spaces between the bosses (90), Fig. 3 (not shown) on the valve member 84 and passage 38 to outlet 32. At a predetermined pressure the pressure responsive member 54 moves against spring 72 until valve head 66 engages the valve member seat 96. Further increase of the fluid inlet pressure produces an upward force on the member 54 assisting the spring 72 and tending to open the valve to deliver at least a portion of the increased pressure to the outlet. This increased fluid pressure in the outlet increases the downward force on the member 54 tending to reclose the valve. These opposed forces cause the valve head 66 to restrict the flow thereby controlling the outlet pressure which increases at a lower rate than the inlet pressure. If the outlet pressure is greater than the inlet pressure fluid flows from the outlet to the inlet between the lip 86 and the chamber wall. Fluid may also flow between the valve member 84 and the abutment 52 and shoulder 64 through the spaces between ribs (88, 94), Fig. 3 (not shown), and bosses (90) during parts of the operating sequence. Fluid leaking past seal 78 is subsequently returned to the chamber 36 by air compressed in cavity 44. The valve member 84 is elastomeric and has a circumferential lip (86), Fig. 3 (not shown), peripheral ribs (88) and projections (90, 94).

Title: Improvements in or relating to tractor-hitched implements
Inventor: FERGUSON HENRY GEORGE
IPC: A01B63/112
Filed: 1953-04-21
Abstract: 791,682. Agricultural implements. MASSEYHARRIS-FERGUSON (SALES), Ltd. April 21, 1954 [April 21, 1953], No. 10872/53. Class 6(1). An implement for attachment to tractor power lifting links 2, 5 is pivotally attached to a frame which is mounted on the lifting links, the implement and frame being held together as a rigid unit by a toggle mechanism which is so arranged that on occurrence of excess draft the implement is freed to pivot relatively to the frame. As shown, the frame comprises members 12 fixed to a shaft 16 to the ends of which are fixed downward arms 17 which carry a crossshaft 14 attached to the lower links 2. The implement is pivoted on the shaft 16 and is provided with an upward arm 20A which is connected by toggle links 22, 23 to the members 12. Further toggle links 24, 25 are connected to the arm 20A and to the central pivot of the first toggle and are provided with a compression spring 29 which resists collapse of both toggles from their normal position shown in Fig. 1, in which the implement and frame are rigidly connected together. If one of the ploughs 11 catches an obstruction the draft increases and " breaks " the toggle mechanism causing the implement to pivot about the shaft 16 so that draft is applied through the shaft 16 rotating the frame about the pivots 15 and moving the top link 5 which acts through a hydraulic control mechanism on the tractor to lower the linkage so that the tractor is relieved of the implement weight causing the ground wheels of the tractor to spin. In a modification the frame is formed so that the implement is connected below the pivot 15 so that when the toggle mechanism " breaks " the draft load continuing after relative pivotal movement of the frame and implement moves the top link 5 and operates an overload release valve in the hydraulic mechanism. Specifications 470,087 and 778,686 [Group XXXI] are referred to.

Title: Fluid pressure regulating valve assembly
IPC: G05D7/01
Filed: 1958-04-03
Abstract: 874,269. Valves. GARRETT CORPORATION. April 3, 1958 [April 5, 1957], No. 10906/58. Class 135. A fluid pressure regulating valve assembly comprises a housing 10 having an inlet 12 and an outlet 14, a valve closure member 30 carrying a sealing washer 15 and co-operating with a seat 18 located between the inlet and outlet ports and a diaphragm 116 secured to the stem of the valve closure member and subjected on its left-hand side to outlet pressure, via a passage 132, in a direction tending to close the valve and on its right-hand side to a control pressure acting in a valve opening direction. The closure member 30 contains a bore 33 whose diameter decreases by steps as the depth increases. The outer end of the bore houses a sleeve 34 in which slides a poppet valve stem 39 having a valve head 36 engageable with a seat 38. The valve head 36 is provided with an orifice 42 open to inlet pressure and communicating with a passage 45 leading to a chamber 26 the pressure in which tends to close the main valve. A port 50 in the stem 39 of the poppet valve also communicates with the passage 45 when the poppet valve is open. The chamber 26 has its outlet controlled by a two-way solenoid-actuated valve 56. A conduit 70 leads from the solenoid valve to an adjustable spring-loaded pressure relief valve 76 sensitive to pressure in the conduit 70 via a conduit 92. This valve maintains a predetermined control pressure which is fed by a conduit 98 and orifice 106 in a piston valve 104 to the right-hand side of the diaphragm 116. In order to maintain an adequate supply of control pressure fluid, regardless of the magnitude of the inlet pressure the poppet valve 36 opens when the inlet pressure drops below a predetermined value permitting inlet pressure to pass into the passage 45 via the port 50 in addition to the flow through the orifice 42. When the valve is closed by de-energizing the solenoid 66 to allow the spring 63 to move the valve member 58 to the position shown in the Figure, a rapid falling away of control pressure is provided by the vents 72 and 74. The reduction in control pressure then permits the piston 104 to move upwards to uncover the ports 101 and allow the pressure in chamber 114 to vent to atmosphere. Inlet and outlet baffle members 28, 19 are provided. The diaphragm 116 actuates a plunger 140 of an electric switch 142 of a remote indicator.

Title: Improvements in or relating to power supply systems for carrier communication systems
IPC: G05F1/52
Filed: 1942-08-07
Abstract: 560,230. Automatic control systems for power supply to carrier wave communication systems. STANDARD TELEPHONES & CABLES, Ltd., and KELLY, R. Aug. 7, '1942, No. 11057. [Class 38. (iv)] Voltage. One or more of the voltages required in a multi-channel carrier wave communicating system, and derived from a.c. mains through rectifiers, is or are regulated by a series connected space discharge regulator, controlled by a thermionic valve, the control electrode of which is subject to the voltage to be regulated, i.e. a voltage across the load circuit, and to a negative bias derived independently from the a.c. supply through a static regulator of the saturating choke type as described, for example, in Specification 547,313 or in U.S.A. Specification 1,985,634. The Figure shows + and - 80 volt supplies for d.c. carrier channels and telegraph transmitters derived. respectively through transformers T5 T7 of which the latter is regulated in the manner set forth and the other controlled by a bias derived from the sum of the d.c. supply voltages so that a balance is maintained between them. A transformer T3 also supplies, for the thermionic valves of the system, anode volts, which are regulated according to the invention. In addition, an unregulated cathode heater supply is given from transformer T1. The bias voltage for regulating the circuits from transformers T3, T7 is' derived from the smoothing condenser C2 at - 100 volts and the primary circuit of transformer T2 includes a saturable transformer T8 whereby this voltage is stabilized ; it is applied in series with potentiometers P1, P3 which determine the voltage' applied from the respective circuits to the grids of valves V17, V19, the anode voltage of which latter is applied to the grids of corresponding regulating valves V4, V11. The regulating valve V10 is controlled by the anode volts of valve V18, the grid of which is subject to the voltage of the + 80 volt circuit biassed by the - 80 volts of the companion circuit. The system includes a synchronous motor M and control relays A, B automatically deferring the closure of a switch b3 energizing the high voltage load circuits for definite time after closure of switch S1 or restoration of supply after failure. The voltages for the d.c. telegraph supply circuits are reduced at low loads by arranging for smoothing inductances L3, L4 to resonate at 100 cycles with the condensers C4, C5. The effect of variations in supply voltage on the regulation is balanced by heating the anodes of valves V17 ... V19 by current from unregulated transformers.

Abstract: 663,940. Thermal switches. CLARKSON, A. April 26, 1949. [April 28, 1948] No. 11083/49. Class 38 (v). [Also in Groups XI and XIII] A thermally actuated switch for stopping the supply of air and fuel to the burner of a water heater (see Group XIII) if the flame is extinguished is provided with a spiral bimetallic strip 100 attached at one end to a shaft 94. A cam 122 mounted on but not fixed to the shaft 94 engages a spring strip 117 anchored at one end and carrying an electric contact 118 at the other. Rotational movement of the cam, caused by frictional contact between it and a collar 126 pinned to the shaft under the action of a spring-pressed ring 128, is limited by engagement of a pin 123 in a recess in the cam, so that operation of the switch to stop the fuel and air supply is made dependent on a sudden fall in the temperature to which the bimetallic strip 100 is exposed. Hot gases are drawn into the tube 87 enclosing the strip 100 and shaft 94. The tube 87 is connected by tubes 85, 90 respectively to the combustion chamber of the heater and to the intake of the air blower, so that hot gases, mixed with air entering through apertures 92, are drawn into the tube. A semi-cylindrical damper 98 carried by the shaft 94 controls the entry of hot gases.

Title: Improvements in electric heating and cooling systems for horticultural houses and cloches
IPC: H05B3/00
Filed: 1944-06-09
Abstract: 581,498. Ventilating buildings. JOHNSON, E. G. June 9, 1944, No. 11105. [Class 137] [Also in Groups XI and XXXV] Air in a horticultural house or the like is maintained between a higher and a lower temperature by an electric fan 15 circulating air over electric heaters 18 on operation of a thermostat at the lower temperature, and when the higher temperature is reached, a second thermostat opens a valve so that the fan draws in and circulates air from the outside, the heater being switched off. Each thermostat has a lag in operation so that it opens and closes at slightly different temperatures. No circulation or heating of air or admission of fresh air takes place between the two temperatures, e.g., 65'-75'F. The air heaters comprising resistance heaters 18 with pins 19 are connected in parallel to terminals 20 and are held by rods 17 below a panel 16 with perforations 23. A motor 13 above panel 16 drives through a shaft 14 a fan 15 below the panel. The roof 10 of the cloche has an opening 12 leading to a duct 11 in which is mounted the motor having ventilation apertures 22 so that fresh air may be drawn through it. A slide valve 24 with apertures 25 is mounted on the lower side of the panel 16 and is moved by a solenoid 27 against a spring 34 so that on operation of a thermostatic switch 33 at the higher temperature, the perforations 23, 25 register and fresh air is drawn in by the fan. The thermostat acts through a cable 28 and a rod 26. When fresh air enters, a ventilator at the lower part of the cloche may be opened by the thermostat 33 to allow air to escape. Air is drawn in centrally and is dispersed sideways. When the temperature falls below 75' the current is cut off and the spring 34 moves the slide 24 so that the apertures no longer register. When the temperature falls below 65', the thermostat 32 switches on the fan and heaters 18. The thermostats are connected in parallel, as shown in Fig. 4. Specification 435,496 is referred to.
