Title: Non-alloying zirconium coating material
IPC: H01J19/28
Filed: 1949-01-31
Abstract: Metal surfaces are coated with a mixture of one part by weight of zirconium oxide and one to nineteen parts of zirconium metal or hydride.  Loss of gettering and heat-radiating properties by alloying of zirconium with the base is thus reduced.  The mixture, with a binder, may be sprayed and, in the case of a hydride-coated electrode, the reducing temperature is sufficient to remove occluded gases, or the coated anode, especially a molybdenum anode, may be baked to reduce the hydride before assembly within the discharge tube.  For iron or molybdenum anodes, the coating may consist of three parts of hydride to one part of oxide. Commercial hydride powder may be milled for twenty-four hours, mixed with the powdered oxide, milled for four hours and then mixed with a binder.

Title: Spring-loaded valves
IPC: B60T8/26
Filed: 1974-01-22
Abstract: 1488353 Valves; proportioning valves AUTOMOTIVE PRODUCTS Ltd 17 Dec 1974 [22 Jan 1974] 02867/74 Headings F2V and F2F A spring loaded valve assembly comprises a bored body 11 open at one end and slidably housing a member 12 which is urged away from the open end of the bore by a compression spring 13 the reaction of which is supported by a retainer 19 secured to the open end of the bore and constructed to be deformable to vary the axial distance between a spring contacting surface of the retainer and the open end of the bore. The axial distance may be reduced by axial force on the end 21 of the retainer to deform an annular part 24. Alternatively, the end (31), Fig. 4 (not shown), may be deformed; corrugations (36), Fig. 5 (not shown), may be formed or the end (33), Fig. 7 (not shown), may be dished. Methods of attaching the retainer to the body by permanent deformation are described. In a reducing valve for the rear brake subsystem of a vehicle, rear brake supply pressure at inlet 15 acts on a smaller area of a plunger 12 than does the pressure at port 16 to the brake cylinders. The thrust on the plunger thus tends to seat a ball valve 14 and is opposed by the spring 13. A second plunger 27 is acted on by pressure of the front brake system via port 28 to reduce the effect of spring 13 and thereby reduce rear brake pressure when front brakes are operating.

Abstract: 567,910. Counters. IGRANIC ELECTRIC CO., Ltd., and RAPLEY, H. H. March 1, 1943, No. 3319. Addition to 556,947. [Class 106 (i)] Apparatus according to the parent Specification for counting articles conveyed in a stream which may be interrupted, comprising a counter adapted to be driven by the conveyer, means whereby, in response to the rear of a stream passing a given point, said counter ceases to operate; and means whereby, in response to the front of a stream passing a second given point, said counter begins to operate, this next count always beginning when the same length of new stream has passed said given point, wherein the counter is controlled by a clutch control element is characterised in that the clutch control element is actuated electro-magnetically. A stream of newspapers maintains a lever 2 in clockwise position to hold a switch 3 closed and thereby a relay 46 energized. Solenoid 47 is thereby held energized to hold levers 48, 50 and bar 13 in raised position. When the stream finishes, lever 2 moves counterclockwise, switch 3 opens and relays 46, 47 de-energise. Bar 13 is pressed downwards but is unable to move until a roller 4, engaging a cam 5 on the rotary part of the counter switch I, enters a recess 6, when a cam surface on the bar 13 declutches the drive from the conveyer to the counting switch, counting during the arresting motion being prevented by the open contacts of relay 46. Counting recommences when a predetermined munber of newspapers have passed the lever 2. So that the papers can be counted in quires of varied numbers, e.g. 26 and 27, the arrangement in Fig. 4 has a selector switch 59 whereby one or other of a set of counting switches 1a, 1b, solenoids 47a, 47b, relays 46a, 46b may be rendered operative. Only one lever 2 and switch 3 are employed in the circuit. If, as in Fig. 4 of the parent Specification, the control points of the stream are spaced apart, so that two levers 2, 2<1> are employed, one controls the switch 3 and the other the solenoid 47. Specification 567,937 is referred to.
