Title: Improvements in or relating to spraying apparatus
IPC: B05B7/12
Filed: 1938-07-23
Abstract: 501,392. Spray - producers. MEECH, T., and BURDETTE & CO., Ltd. July 23, 1938, No. 21946. [Class 69 (iii)] In spray - producers of the kind in which the needle valve 14 for the liquid is operated by the air pressure, the stem of the needle valve carries a spring - controlled crosshead 22 which is acted upon by the stems of a plurality of pneumatic rams 21 the heads of which move in separate air chambers 19 connected to the air inlet 4, the air having no access to the chamber 17 in which the cross-head moves or to the bore through which the stem of the needle valve passes. The rear body portion 1 of the apparatus has a screwed ring 3 which screws into an annular recess 13 in the spraying head 2 and is connected by two tubular pillars 16 with the chamber 17 which has bores 19 closed by plugs 20 through which pass the stems of the rams. The ram heads are of conical shape conforming to seatings in the plugs 20 so as to seal the bores in the plugs when in' their upper position. Due to the lost motion between the ends of the ram stems and the cross-head 22 the air is supplied through the nozzle openings 8 before the liquid valve is opened. The valve stem 14 passes through a gland 15 and is in threaded engagement with the cross-head 22, rotation of which is prevented by pins 23 engaging holes 24. The stem passes freely through the end cover 18 and terminates in a knob 26. By rotating the knob 23 the crosshead 22 is adjusted on the valve stem 14 to alter the valve opening, and by pulling the knob 26 outwardly against' the spring 25 the needle valve can be retracted from the discharge hole of the nipple 9 to remove obstructions.

Patent GB-911304-A (GB)
Title: Devices, particularly for motor vehicles improvements in and relating to power-assisted steering
IPC: B62D5/08
Filed: 1959-07-01
Abstract: 911,304. Steering vehicles. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. July 1, 1959 [July 11, 1958], No. 22662/59. Class 79(5). A power-assisted vehicle steering mechanism comprises a double acting or two single acting auxiliary force pistons controlled by valves and on each pressure side of the auxiliary force device, a non-return valve operated in the event of a vacuum in the cylinder chamber to cause pressure fluid to return to that chamber. The system may comprise steering shaft 2 passing throughan aperture in a lever 3 and carrying a gear wheel 61 which meshes with gear wheel 62 mounted on the steering worm, not shown, and a double acting auxiliary force piston 27, 28 operating as described in Specification 738,383. Pressure fluid from a reservoir 9 is fed by a pump 11 through a conduit 12 to a control comprising valves 5, 6, 7 and 8 and according to the positions of the valves through conduits 23 or 24 to one side or other of the double acting force piston or into the return chamber 32. The valves 7 and 8 are reaction valves in conduits 30 and 31 respectively leading from the pressure pipes 23 and 24. The space between the pistons 27 and 28 is connected to the return chamber 32 by a conduit 37. Non-return valves 43 and 44 are inserted in the pistons 27 and 28 as shown or in conduits between the pipes 23 and 24 and return conduit 37. On moving the steering wheel, e.g. to the right, the control lever 3 is moved to the right by the reaction pressure in the gearwheels and the valves 6 and 8 cut off the pressure pipe 24 from the chamber 32 and at the same time valves 5 and 7 connect the pipes 23 and 30 to the return chamber 32. The auxiliary force piston is thus pushed to the left. In the event of a failure of the hydraulic system, the circuit of the pressure medium is interrupted by the pump and by the movement of Control lever 3 a vacuum is produced in the cylinder chamber 26 by which the non- return valve 44 opens and fluid passes from the chamber 35 into the cylinder chamber 26. If the pump 11 does not supply pressure fluid, a piston 61 in valve 63 closes line 66 and the pistons 40 and 41 exercise a pumping effect through valve 5 or 6. The formation of a vacuum in pipe 12 is prevented by a restricted orifice 65 in valve 63.

Abstract: 1,223,063. Hydraulic brakes. FORD MOTOR CO. Ltd. 5 May, 1969 [19 June, 1968], No. 22732/69. Headings F2E and F2F. A dual brake system for a vehicle has first and second pairs of brakes 12, 14, the linings of' each brake being actuated by an hydraulic motor having first and second motor chambers 88, 120, 128 and 78, 130 respectively, the first of which 88 and 120, 128 are connected to one pressure chamber 32 of an hydraulic master cylinder 10, and the second of which 78 and 130 are connected to a further chamber 36 of the cylinder whereby on loss of pressure in either the first or second motor chambers the four brakes are still actuated by virtue of an increased pressure in the remaining motor chamber. In the embodiment shown chamber 32 communicates via port 46, pipes 156, 156A with a bore 90 formed in the motor cylinder of each of a pair of disc brakes 12 and communicating with chamber 88, and via pipes 156, 156B and port 146 to the motor chambers 120, 128 of a pair of drum brakes 14. Chamber 36 communicates via port 48, pipes 158, 158A and port 80 with the second motor chamber 78 of each brake 12 and via pipes 158, 158B, port 152 to the second chamber 130 of each brake 14. Pistons 64 and 122, 108 respectively actuate the disc and drum brakes. The ratio of displacements of the motor chambers of each brake may be equal to that of the master cylinder pressure chambers so that on loss of fluid in either first or second motor chambers the fluid pressure in the other is effectively doubled. Leakage between seals 84, 76 and 108, 118 of brakes 12, 14 respectively is detected by bleed passages 92, 154. In a further embodiment each motor piston has a reduced section sliding in a corresponding reduced bore, the shoulder between the larger and smaller bores defining with the shoulder joining the two piston sections a first motor chamber and the smaller head of the piston defining with the cylinder end wall a second motor chamber.
