Title: Means for operating a drop-head of a motor-car body
Inventor: ORR JOHN HEWITT
IPC: B60J7/12
Filed: 1953-01-24
Abstract: 734,434. Hydraulic control systems; valves. CARBODIES, Ltd. Sept. 30, 1953 [Jan. 24, 1953], No. 2117/53. Classes 69 (2) and 135. A hydraulic system having jacks for operating a vehicle hood is provided with valves which are normally open so that the drop head may be moved by hand, and the jacks are operated in at least one direction by the closing of a valve. In one embodiment the hood is lowered by operating a switch 46 to energize a motor driving a pump 32 and to energize a solenoid 48 closing a valve 41. The pump 32 supplies a jack 30 for forwardly tilting a seat as described in Specification 710,371, [Group XXXII]. When the jack 30 is fully extended, fluid is admitted through a pipe 38 to the annular ends of cylinders 26c of the hood-operating jacks, retracting the jacks. The expelled fluid passes through a valve 43 to a reservoir 31. To raise the hood the switch 46 is operated to energize the motor and a solenoid 49 for closing the valve 43. In this case, after the jack 30 has fully tilted the seat forwardly, fluid is admitted to both ends of the cylinders 26c and the jacks are extended. On starting the pump 32, fluid is supplied to a valve 35 through a pipe 34. The fluid raises a piston 60, closing members 63, 64 and permitting communication between the pipe 34 and a pipe 36 through a passage 62. When the hood operating jacks have been actuated pressure develops in pipe 36 until piston 60 is moved to open members 63, 64 for the pump delivery to pass to the reservoir. When this occurs a valve 74 is unseated and contacts 70, 71 of a warning system are closed. In another embodiment separate inlet and exhaust valves are provided for each end of the cylinders 26c, and in a further embodiment single-acting jacks having a spring-operated return stroke are provided.

Title: Method and apparatus for regulating the depth of penetration of a tractor-drawn plough
IPC: F02D1/00
Filed: 1965-01-19
Abstract: 1,096,181. Tractor power lift mechanisms. E. SATZGER. Jan. 19, 1965 [Jan. 20, 1964], No. 2262/65. Heading A1P. [Also in Division F1B] A tractor power lift mechanism has draft control operative in dependence on the delivery rate of a fuel injection pump feeding the tractor engine. Conduit 11 is connected to the bypass control of the injection pump and communicates changes of pressure therein to a chamber 12 to move a piston valve 14 whereby hydraulic pressure fluid is either supplied from pump 21 to the operating ram of the lift linkage through recess 24 or is exhausted from the ram through conduits 28, 29 in the piston 14 and chamber 13. In the central operating position shown fluid from the pump 21 is fed directly to exhaust through recess 23. The pressure in the conduit 11 is regulated by a throttle valve 33 connected to the discharge conduit 20 and is also controlled by a throttle 19 on an auxiliary piston 15 biased by a spring 18 which is adjustable to set the initial depth of operation of an attached implement. A manual depth setter consists of a throttle valve 30 connecting the chamber 12 directly to the discharge conduit 20, and this depth setter may be augmented or replaced by a further manually adjustable valve 31 in a conduit connecting the supply and discharge conduits 11 and 20. Movement of the auxiliary piston 15 is damped by a throttle valve 32 and which is adjustable to vary the rate of response of the system. A valve 34, in the central position, directs part of the fuel pressure in conduit 11 to discharge conduit 20 but is closed by an increase in the hydraulic fluid pressure in conduit 35 to compensate for the power needed from the tractor engine to operate the hydraulic system. In an embodiment the hydraulic pressure fluid is itself throttled by the auxiliary piston 15, the fuel pressure from the injection acting only in the chamber 16. In a further embodiment the piston valve 14 has a longitudinal bore which is in the supply conduit of the injection pump and this bore provides a throttle for the fuel pressure.

Patent GB-879716-A (GB)
Title: Fluid pressure operated systems
Inventor: HANCOCK KENNETH GEORGE
IPC: B64D37/20
Filed: 1957-01-22
Abstract: 879,716. Hydraulic control systems. ELECTRO-HYDRAULICS Ltd. Jan. 22, 1958 [Jan. 22, 1957], No. 2336/57. Addition to 801,512. Class 69 (2). The system of the parent Specification is modified in that the selector valves 12 for switching from the normal to the emergency service line are controlled by a switch 17 actuated by a piston 5 in a pressurized balance tank 3 connected by pipes 4 to both storage tanks 2 in such a way that normally gravitational loss of fluid is prevented even when the system is upside down as may happen in an aircraft. Normally, separately driven continuously running pumps 1, fed from respective storage tanks 2, feed the normal service line via selector valves 12, filters 11 and non-return valves 13. Fluid is fed back to the storage tanks from the service via return line 18, non- return low-pressure valves 20, and calibrated orifices 19 to allow for equal fluid return to both tanks 2. The storage tanks and the balance tank are pressurized by fluid from the outlet of one of the pumps 1 acting over line 9 on a piston 7 connected to piston 5. Should a fault occur which causes a drop in pressure in either storage tank, piston 5 is raised to operate the switch 17 to switch the selectors 12 to supply the emergency service line at 16 over non-return valves 15. An isolating valve 23 may be provided in the emergency service line which closes when switch 17 is operated. This prevents supply of fluid over this line until a particular emergency service has been subsequently selected. Suction valves 21 permit air to enter the tanks 2 when they partially empty during such an emergency operation, and a valve 22 normally venting the emergency line to tank is closed upon operation of any emergency service. Should the balance tank 3 fracture, or the pressurizing action of piston 7 fail, the switch 17 will not operate; the system remains on normal and the suction valves allow operation. Modified arrangements for pressurizing the balance and storage tanks from the pumps 1 via the piston 7 are described, Figs. 1, 2 (not shown). Alternatively, engine bleed-air may be used to act on piston 7.

Title: Improvements in temperature regulators for electric cooking ovens
IPC: H01H35/26
Filed: 1941-02-28
Abstract: 543,762. Automatic control systems for electric ovens; thermal switches. WILCOLATOR CO. Feb. 28, 1941, No. 2753. Convention date, Feb. 28, 1940. [Class 38 (iv)] [Also in Group XXXVII] Temperature.-A cooking oven is provided with broiling and baking elements 30, 37 and a control switch, Fig. 2, comprising two pairs of elements 27, 32 coupled respectively by members 29, 36 and biased to close independent circuits for the heating elements. An actuating member 63b for the " bake " switch is associated with a cam 89 whereby it is locked in the open position in the " off " and " broil " positions of a rotary control handle 83. An actuating member 63a for the "broil" switch is associated with a tumbler or latch 98 whereby it is locked open in the "off " position until released by a pin 104 on the cam 89 as the control handle moves into a " bake " position. Both heating elements then operate to raise the oven temperature to that determined by the setting of the control handle 83. A thermostat 43 operates at the set temperature to open both switches whereupon the latch 98 locks the " broil switch open and the thermostat operates upon the " bake switch alone to maintain the temperature. The preheating operation can be suspended by actuating a selector knob 110 which causes a second cam 107 to engage the actuating member 63a for the " broil switch to lock this in the open position, but this cam is actuated further by a projection 90 on the control cam 89 when it is moved into the " broil position, so that the broil switch is then permitted to close. The thermostat is of the bellows type and operates, together with a bimetallic element 51 correcting for variations of ambient temperature, to reverse the flexure of a snap element 54 which moves the actuating members 63a, 63b for the switches. The thermal control devices are removable as a unit from the control switch casing. The control handle 83 is removable from an outer sleeve 73 rotatable in the casing 20 to permit calibration which is effected by freeing an inner sleeve 71 from the outer sleeve by operating a screw 75 to release a wedge clamp 76, whereupon the inner sleeve is adjusted to cause the snap member to operate when the oven is at a measured temperature; the outer sleeve is then set to a position such that this temperature indication on a washer 84 carried by the outer sleeve coincides with a fixed index mark 87, the wedge clamp is tightened and the control handle replaced. Specification 544,367 is referred to.

Title: Improvements in ornamental fabric and method of producing the same
IPC: D06C29/00
Filed: 1930-01-28
Abstract: Pebble or cockle effects are produced by the treatment of a mixed fabric having its warp, or weft, or both composed of cellulose acetate or other organic derivative of cellulose and other yarns such as cotton, reconstituted cellulose, wool, or silk with a reagent causing shrinkage of such other yarns.  The cellulose acetate yarns may be replaced in part by yarns of other fibres which have been treated with a shrinking agent before weaving.  The two kinds of yarn may be of low and high twist, alternating in the warp, or weft, or both.  In an example, yarns of an organic derivative and of low twist are used with highly-twisted yarns of natural silk.  Water may be used as the shrinking agent, while water or a soda bath is used for shrinking a woollen yarn component of a fabric.  When it is desired to shrink the cotton yarn component, the fabric is treated with caustic alkali without tension thereby shrinking and mercerizing the cotton and causing the other yarn of cellulose derivative to cockle. The shrinking-agent may be applied over the whole surface of the fabric or in parts only by brushing or spraying on a stencil.  The resulting fabrics may be dyed to obtain solid colour or cross-dyed effects.  The Specification as open to inspection under Sect. 91 (3) (a) was not limited to fabrics containing organic derivations of cellulose.
