Title: Reversing valves for controlling the flow of fluid in a dual line type of system
IPC: F16K11/07
Filed: 1975-04-24
Abstract: 1467773 Valves; lubricating EATON CORP 24 April 1975 [3 May 1974] 16965/75 Headings F2V and F2A A valve 10 for a lubricating system comprises a diverter valve 14 for switching the flow of lubricant between two feed lines 116, 117, and a pilot valve 13 which controls the movement of the diverter valve 14. The pilot valve comprises two axially aligned pistons 40, 41 joined together by a slider block 67 forming part of a toggle mechanism which retards the initial movement of the pistons and accelerates their final movement. In addition to the slider block the toggle mechanism comprises a slipper plate 80, in a groove (79<SP>1</SP>) of which the slider block is guided, a throw link 77 and a spring loaded guide block 97. In Fig. 7 the valve 10 is supplied with lubricant under pressure through port 120. With the valves 13, 14 in the position shown lubricant flows to line 116 to feed a conventional dual line valve 118 which creates a back pressure on line 116. This pressure acts on the left-hand end of the pilot valve 13 to move it to the right which action feeds pressure to the right-hand end of the diverter valve 14 to move it to the left to supply pressure to the alternate line 117. The cycle is then repeated and thus lubricant is supplied alternately to the lines 116, 117. The diverter valve may have an extension 35 to act as a visual indicator or to operate a switch 170 to control a pump pressurizing the supply.

Title: Improvements in safety razors
IPC: B26B21/18
Filed: 1937-06-19
Abstract: 495,123. Safety razors. WARD & SONS, Ltd., T. June 19, 1937, No. 17110. Convention date, June 19, 1936. [Class 30] Relates to safety razors of the type in which a guard plate, between which and the back plate a blade is clamped, has a mushroom-headed spindle engaging spring jaws displaceably mounted in the razor handle. A handle 1 of tubular form carries a back plate 2 between which and a guard plate 3 a blade 4 having the usual indexing holes is clamped. A central boss 5 of the plate 3 has a mushroom head 7 adapted to be engaged behind spring jaws 8 on a sleeve 9 displaceable within the handle 1. This sleeve is forced down to clamp the blade by a relatively strong spring 15 bearing on a socket 17 and on a flange 18 of the sleeve. In this position the jaws 8 lie within a constricted part 16 of the socket 17 and are prevented from spreading. Within the sleeve 9 is a plunger 10 with upper bevelled end 13 adapted to engage bevelled parts 14 on the jaws. The plunger is actuated against the force of a spring 12 bearing on a flange 19. To withdraw the blade, the end 11 of the plunger 10 is pushed in until the bevelled end 13 meets the jaws. Further movement pushes up the sleeve 9 until the jaws pass the constricted part 16 and are spread apart by the thrust of the bevelled end of the plunger. The head 7 is thus disengaged from the jaws and the blade can be removed. To re-insert the blade it is placed on the plate 3, and the head 7 is inserted between the jaws 8 and pressed so as to force down the plunger 10 until its bevelled end leaves the bevelled parts of the jaws 8 which then spring inwardly under their own elasticity and grip the head under the action of the spring 15.

Title: Safety valves
IPC: F02K9/56
Filed: 1953-06-19
Abstract: 743,357. Valves. DE HAVILLAND ENGINE CO., Ltd., HALFORD, F. B., and CLEAVER, A. V. May 14, 1954 [June 19, 1953], No. 17122/53. Class 135. A safety valve, which may be a cut-off, blow-off or diverting valve, for protecting an apparatus against excessive pressure at any one of a number of points in the apparatus, comprises a piston-actuated valve member, connections placing the piston in communication with any of the points to subject the piston to pressure to actuate the valve, and means to retain the valve in its actuated position even after the pressure applied to the piston has fallen. As shown for cutting off the fuel supply, e.g. hydrogen peroxide, to a rocket motor should the pressure at selected points on the motor rise above a safe value, the valve comprises a body 10 having an inlet 15 and an outlet 16 for the fuel, a piston valve 12 connected by a rod 20 to a piston 19 urged downwardly by a spring 17 and a spring-loaded plunger 24. The selected points on the rocket are connected through relief valves and connectors 26 to a chamber 22 below the piston. When the pressure at a selected point rises above a safe value, determined by the loading of its relief valve, the piston and valve are raised to isolate valve ports 13 from body ports 14 to close the valve, the plunger 24 engaging beneath a projection 23 of the piston to hold the valve closed and thus permit examination of the motor for damage. The valve can be reset on removal of a cap 25.

Abstract: 539,924. Spark arresters; exhaust silencers. TONGEREN, H. VAN. Dec. 3, 1940, No. 17222. Convention date, Nov. 24, 1939. [Class 25] [Also in Group XXVII] A spark arrester suitable for mounting in the exhaust conduit or chimney of large Diesel engines comprises a cylindrical casing 5 having frustoconical bottom and top walls 6, 7 formed with co-axial inlet and outlet openings 8, 9 of approximately the same diameter and containing a biconical deflector 10 connected to the bottom wall by stationary spin-inducing vanes 11 and to the top wall by bent baffle vanes 12 surrounding a perforated cylinder 20 containing radial baffles 17, 18. The sparks and other particles whirling in the casing 5 are discharged through one or more skimming openings 15 into cyclone separators 13 connected to a bunker and chimney. The whirling gases are suddenly deflected on entering between the baffles 12 thereby causing the heavier particles to rebound outwardly. The cylinder 20 and baffles 17, 18 act as a silencer, the baffles preferably consisting of spaced perforated metal sheets enclosing glass or steel wool or other sound-deadening material. The diameters of the casing and deflector are less than twice and one and a half times, respectively, the diameter of the openings 8, 9. In another construction three coaxial series of baffle vanes 12 surrounding three coaxial cylinders increasing in diameter upwardly are provided, the vanes being arranged more closely in the upper series so as to equalize the quantities of gas passing through each series.

Filed: 1943-10-20
Abstract: 568,907. Cutting-machines for cylinders. COSSOR, Ltd., A. C., and REEVES, A. T. F. Oct. 20, 1943, No. 17234. [Class 31 (i)] [Also in Group XXXVI] A cutting-machine for making a peripheral cut on a cylindrical article, such as a multistrand electric cable such as is shown in Fig. 2, is constructed with a turntable 9 having a central orifice to receive the cable coaxially, and a slide 4 carrying a knife 2 is mounted to slide so that the knife moves radially of the cable as it is carried around the fixed periphery of the cable so that the knife cuts completely through the plastic outer cover of the cable and cuts through the coverings 24, 25, but is retracted so as to leave the sheaths 20, 21 of the two cables uncut. The slide 4 is acted upon by a spring 11 which tends to withdraw the cutter from the cable, but the slide is moved inwardly under the action of centrifugal force upon the slide and upon a weighted member 14 mounted in ball-bearings at the end of the slide 4. The member 14 coacts with an outer cam member 16 which controls the motion of the slide and permits a large inward movement of the knife in the direction of the axis 19-19, but restrains the inward motion in the direction of the axis 18-18. For cutting through the sheathing of a concentric cable, the cam member 16 is made of circular form. A balancing weight 28 is attached to the turntable.

IPC: B65D83/14
Filed: 1954-06-11
Abstract: 750,758. Spray-producers. COTY, Inc. June 11, 1954, No. 17279/54. Class 69 (3). Liquid 2 within a container 1 is drawn up a tube 10 and sprayed from an orifice 8 by a gas which is released by a valve 17 from a reservoir 14. The valve is normally urged by a spring 21 to close a passage 9 leading to the spray orifice, and when the valve is depressed by a button 19 an outlet 16 from the gas reservoir is closed and the gas within a chamber 11 flows to the orifice and causes spraying. In order to effect a more continuous spraying with a single actuation of the button the valve may be so short that it does not close the outlet 16 in the spraying position, and the valve spring is positioned between the valve button and a washer 7.

Title: Improvements in electric timing circuits
IPC: H03K17/288
Filed: 1943-10-23
Abstract: 580,179. Electric timing control circuits. GUMMING, W. R., YOUNG, W. F., and ROSE STREET FOUNDRY & ENGINEERING CO., Ltd. Oct. 33, 1943, No. 17480. [Class 38 (iv)] A timing circuit, particularly for use with spot welding machines, comprises a grid controlled electronic valve 28 having in its anode circuit the winding 24 'of a relay which has normally open contacts 52 in a circuit 54 to be controlled and normally closed contacts 38 in the charging circuit for a grid timing condenser 40. The valve is energized from a potentiometer 10, 12 connected across a smoothing condenser'16 charged from an alternating current supply through a rectifier 14. With the timing condenser and grid 44. negatively biassed by the potentiometer tapping 18, timing is initiated by closing a switch 34 thereby allowing the grid to assume a positive potential. The valve then becomes conducting but the inductance of relay winding 24 delays flow of anode current and thereby allows the grid to reach a higher potential. When anode current flows, contacts 52 close to complete the controlled circuit 54 and contacts 38 open to prevent further rise in grid potential. Condenser 40 then commences to discharge through resistances 46, 48 and when its potential has reached a low value the valve becomes non-conducting and the relay contacts assume their initial position. The discharge time of condenser 40 is controlled by potentiometer tapping 18 and switch 50. In order that discharge shall not commence until welding current flows, a normally open switch 56, closed by a winding 58 under the control of primary or secondary current flowing in the welding transformer, is arranged in the grid circuit of the valve.
