Title: A valve for controlling the flow of fluids
IPC: G05D16/18
Filed: 1934-10-30
Abstract: 451,339. Valves. PHILLIPPS, M. T., Esplanade South, Henley Beach, Australia. Oct. 30, 1934, No. 31067. [Class 135] A valve for regulating fluid-flow more particularly in water pipes is provided with a partition 4 separating the inlet side 2 from the outlet side 3 through which a cylindrical plunger 6 passes and is subjected to the same fluid pressure at both ends, the plunger being provided with a single valve-surfaced flange 13 intermediate its ends for engagement with a valve seating 5 on the partition, and with an opening or openings 6<a> adjacent to the fiange to permit the flow of fluid from one side of the partition to the other. In one form, Fig. 1, apertures 11 in the plunger admit high-pressure fluid to the upper side 12 thereof to balance the fluid pressure on the lower side, but in alternative constructions, a byepass connection may carry highpressure fluid to the side 12 or an additional passageway similar to the passageway 14, may be formed in the main casing so as to extend to the upper side of the plunger. The fit between the flange 13 and seating 5 is imperfect so that a slight liquid film is present between the parts 13, 5 in the closed position to provide sufficient upward pressure to balance the downward delivery-pressure on the upper side of the flange. The plunger may be connected directly, or indirectly as shown, to a lever 20 pivoted at 22 and attached at one end to a weighted or spring-loaded ram 25 which may be subjected on its under-side to delivery-pressure from the delivery-pipe 3<a> through a two-way valve 29 so that the position of the main valve 13 is controlled by the pressure. As an alternative, the main valve may be operated to close automatically when the delivery reservoir is filled to a certain level, and for this purpose the twoway valve 29 is adjusted so that the ram cylinder is connected to the high-pressure side 14 by a pipe 30. A branch 32 is taken from the pipe 30 to a ball-cock in the cistern being filled, and the leakage through the pipe 32 prevents operation of the ram to close the main valve until the ball-cock closes the pipe 32 due to the fluid reaching the required level; an over-riding manual control of the main valve which may be a remote control, can be provided by means of a hand-operated valve controlling an independent pipe connection between the high-pressure side 14 and the ram cylinder.

A device for recording and reproducing movements of the jaws comprises two bows 1, 2 on each of which a bite device 14, 15, for fixing to the upper and lower jaws, respectively, is adjustably carried, and coacting recording devices on the bows for recording movements of the bite devices relative to one another in response to movement of the jaws. Bite trays 14, 15 are supported by rods 12, 13 which selectively engage apertures in plates 10, 11 carried by each face bow 1, 2. The upper bow has depending members 6, 7, 8 which engage mouldable material 9 in cups 3, 4, 5 on the lower bow. In use a tray is cemented to the patient's upper and lower teeth respectively and the bows are connected to the trays by the rods. Relative movement of the trays in response to jaw movement is recorded by the depending members as paths traced in the mouldable material. The ends and middle of the upper bow may carry pointers (not shown) which are adjusted to register with fixed marks on the patient's face so that the device may be repositioned for subsequent recordings. The trays and their supporting plates may be replaced by plates 21, 22 (Fig. 5) for supporting dental models 19, 20 for adjustment so that they will reproduce the movements of the patient's jaws in accordance with the paths traced in the mouldable material. The mouldable material bearing the record may be hardened or replaced by duplicates in wear-resistant material.

Title: Improvements in snap acting electric switch
Inventor: TYLER HUGH JEAN
IPC: H01H5/04
Filed: 1958-09-30
Abstract: 896,121. Retractive switches; snap-action switches; switch contacts. ROBERTSHAWFULTON CONTROLS CO. Sept. 30, 1958 [Jan. 13, 1958], No.31195/58. Class 38 (5). A switch comprises actuating and actuated members, each of which has a free end, the members being interconnected by a resilient over-centre snap-action means and being operably connected at their non-free ends to cause a wiping movement of the movable contact, which is on the actuated member, in a direction perpendicular to the snap-action movement. In one form, Fig. 1, the actuated member comprises an arm 22 mounted at 24 and carrying a contact 20 movable between fixed contacts 16, 18. The actuating member 36 is attached at 48 to a cranked part of the arm 22 and at its free end has notches 44 in which is pivoted a lever 50 connected by a tension spring 66 to the arm 22. Stops 63, 64 on the lever 50 limit mdvement thereof and, when force is applied to the member 36, increases the contact pressure until the contact is. snapped over. As the member 36 is tilted, the arm 22 bends about a projection 34 and thus produces the wiping action. In a modification, Fig. 7, the lever 150 engages pivots on the arm 122 and is connected by a spring 166 to the actuating member 136. In another form, Fig. 8, the member 236 has a pivot 235 and bears on a bell-crank lever 270 in turn pressing on the cranked portion 226 of the arm 222. The coil-spring and lever may be replaced by a C-spring 366 arranged between the free ends of the member 336 and arm 322, Fig. 9. In the above arrangements, the switch restores when the actuating member is released, due to the resilience of the cranked portion. In further arrangements, Figs. 13 to 18 (not shown), a separate coil return-spring is provided, and in Figs. 13, 14 (not shown), the actuated member is embraced by the actuating member, whereas in the other embodiments these two members are superimposed.

Abstract: 1,056,747. Road-traffic signalling apparatus. LABORATORY FOR ELECTRONICS Inc. Aug. 7, 1963 [Aug. 10, 1962], No. 31224/63. Heading G4Q. A system for controlling traffic at two intersections of first and second roads with a third road common to both intersections comprises two traffic-actuated subcontrol units SC1, SC2 interlinked by a unit MSA which controls their operation in one of a number of modes of operation. As described, the system is applied to two junctions comprising entry and exit ramps joining an express way with an artery 20, the junctions are each controlled by lights L1, L2 and the system may be switched from a first mode of operation to a second depending on the traffic flow. The traffic flow is measured individually at two separate points, and the mode change over may take place either when one of these measurements exceeds a predetermined value, or when both of them exceeds the value. With low traffic volume, each junction may operate in one of three phases A, B, AD, Fig. 2, and switching between these phases takes place according to the traffic demand. When the traffic volume increases above a certain predetermined value the system switches to a second mode of operation having phases AM, B, C, Fig. 3. Means are also provided in the controller for varying the duration of each phase in accordance with the demand sensed by detectors DN, DS, D1W, D2W, D3W, D1E, D2E, D3E, subject to an overriding maximum time period. As shown in Figs. 2, 3, only certain combinations of phases are permissible at the two junctions and interconnections are provided between the two controllers to ensure that a change of phase at one junction results in any necessary change being made at the other. Circuits of the controllers and mode switching unit are described, Figs. 4-8 (not shown).

Abstract: 1,070,530. Cathode ray storage tubes. TEKTRONIX Inc. Aug. 4, 1964 [Aug. 1, 1963], No. 31225/64. Heading H1D. A low-capacitance storage screen for a cathode-ray tube, having one or more flood guns and a further gun switchable for use for either reading or writing (Fig. 1, not shown), includes an insulating support coated on one side with a conductive material having a plurality of spaced apertures extending through the coating to the support, and secondary electron emissive dielectric contained within the apertures. The dielectric material 62, which may be a phosphor for direct viewing, is disposed on the tube faceplate 56, in the apertures of the mesh grid formed by intersecting lines of conductive material 32. The screen may be produced by coating the faceplate with aluminium, silver, or tin oxide, superimposing a coat of photosensitive material which is exposed to light transmitted through a film containing an image of the desired mesh, and developing and etching to remove the unexposed material and the underlying conductive coating. The photosensitive material above the mesh is then removed, and a photo-sensitive/dielectric mixture applied as a coating; this is exposed to light passed through the grid, the unexposed portions are washed off, and the plate is then heated to remove the photo-sensitive material from the dielectric. In a second method, the faceplate is coated with a photo-sensitive solution containing a powder-e.g. a silicate, phosphor, or metal oxide-which is insoluble therein; exposed to the light image of a mesh; developed and the unexposed regions washed off; coated with an evaporated conductive layer; the remaining photo-sensitive material and its overlying coating removed by the use of heat and abrasive; whereafter the last three stages of the previous process are applied. Some of the above steps may be dispensed with if the powder in the initial mixture is itself capable of forming an adherent conductive coating on the faceplate after heating. A further method employs a stripping type of photographic film. In a modified screen (Fig. 4, not shown), permitting the use of photoconductive dielectric material, the regions of the latter (62<SP>1</SP>) are insulated from one another by glass ridges (68). This structure may be provided by etching through a masking coating of suitably exposed and developed photo-sensitive material, or by fusing on to the faceplate intersecting lines of glass frit.
