Title: Improvements relating to electric time switches
IPC: G04C23/34
Filed: 1926-07-10
Abstract: 255,097. Aron Elektrizitõtszõhlerfabrik Ges., H. July 11, 1925, [Convention date]. Actuating.-Relates to the switching devices used in shop-window and like installations which have arrangements, e.g. an all-the-year cam, for switching on and similar means for changing over to a lower tariff. These means are inaccessible to the consumer, but, by adjusting a wheel h relative to a wheel i in a clock-work train, the switching off time can be adjusted by him. In the switching-on means, although the switching-on cam is designed to work for the whole year in accordance with the estimated nightfall, the tariff-changing cam only partly so corresponds and is otherwise circular so that a lower tariff, for instance, is only in force during that period after a definite time e.g. 7 p.m.

Title: Improvements in or relating to blind riveting and blind-riveting tools
IPC: B21J15/04
Filed: 1954-06-14
Abstract: 776,929. Blind riveting. TUCKER EYELET CO., Ltd., G., and HENSHAW, J. N. June 14, 1955 [June 14, 1954], No. 17368/54. Class 83 (4). A blind-riveting tool comprises abutment means arranged to engage one end of a rivet to restrain bodily movement of the rivet relative to the work during setting, a sleeve mounted to slide relative to the abutment means and arranged to project, before the mandrel stem of a blind-riveting assembly is pulled in operation of the tool, into the space within the rivet around the mandrel stem, and mandrel pulling means. A blind-riveting assembly for use with the tool comprises a cold-forged steel mandrel 14 (Fig. 1) having a round head 16 and a stem 18 provided with a screw-threaded portion 22 and a light-alloy hollow rivet 24 having a head 26 and a thickened end portion 32 the bore of which is a close fit on the mandrel stem. The tool comprises a steel tube 42 and a nose piece 44, a rubber sleeve 46 surrounding the tube to provide a handgrip. Within the tube is slidably mounted a collet 48 comprising a solid rear portion 50 and a forward end portion split longitudinally to provide four jaws 52. When the collet is unconstrained, flange portions 54 on the jaws enter a recess 56 in the nose piece to enable the screw-threaded portion of the mandrel stem to be inserted in the jaws. Within the nose piece is housed a rivet-entering sleeve 66 having a rear portion 70 provided with a part-conical face 72. In its foremost position part of the sleeve projects beyond the end of the nose piece. Forward and rearward movement of the collet is effected by a lazy-tongs mechanism. A pivot pin 80 passing through the rear end of the tube 42 supports four links 82 two on each side of the tube. A second pin 84 passing through portion 50 of the collet and through slots 86 in the tube 42 provides support for levers 88. The links 82 are pivoted one to each lever 88 near the pin 84. A spindle 94 carrying a handle 92 supports links 96 pivoted one to each end of the levers 88. Movement of the handle towards the work opens the levers 88 and retracts the collet to grip the mandrel and pull it through the rivet (Fig. 6). The jaws open of their own accord when the collet moves back into its foremost position any tendency to retain their grip being overcome by a part-conical surface 62 on the jaws engaging the part conical surface 72 on the sleeve 66. For rivet assemblies having no space within the rivet around the mandrel stem a shorter sleeve 66 which does not project from the nose piece is utilized.

Title: Fuel supply system and method for metering and atomizing liquid fuel for use with internal combustion engines
IPC: F02M9/02
Filed: 1975-04-28
Abstract: 1494142 Spray carburetters WHBEEKHUIS 28 April 1975 17532/75 Headings F1B and F1H The induction passage 28, 33, 48 provides an intake passage for an associated engine and fuel is drawn from a fuel chamber 56 in response to the effects of a shock wave propagated along the passage at the result of opening of the engine inlet valve and the pressure drop due to the air-flow through the passage. A slot 101 connecting the induction passage downstream of the fuel outlet passage 54 to atmosphere provides for attenuation of shock waves reflected at the upstream end of the induction passage. A throttle slide valve 31 formed from a phenolic laminate is movable transversely of the induction passage and has a bore 32 movable into alignment with the induction passage by operation of a cable 41 against the return spring 36. A slot (102) Figs. 1 to 3 (not shown) is formed in valve receiving recess 29 and opens to atmosphere through a hole (103) and to the induction passage under the control of the valve 31. The controlled slot modifies the suction produced by the shock wave and provides for increase in air/fuel ratio with decrease in throttle opening. A predetermined fuel level, not extending above the orifice 53, is provided in the chamber 56. The chamber 56 may be connected by a tube 66 to the bottom of an insulated fuel tank (86) Fig. 10 (not shown) closed apart from the connection of a tube 68 to the top of the tank. The tube 68 provides for the creation of a partial vacuum in the tank when its opening 69 is covered by fuel to prevent further fuel flow from the tank. An overflow tube 71 extends into the chamber 56. The fuel may be supplied to the constant level chamber (111) Figs. 11 and 12 (not shown) by an engine driven pump (116) from a tank (113) and via a regulator (116) operated conjointly with the valve 31. The predetermined fuel level is maintained by an overflow tube 71 through which fuel returns to the tank. The pump may supply the constant level chambers of the plurality of carburetters of an eight cylinder engine (Fig. 12). The carburetter may be of side draught type and supply the crankchamber of a two-stroke engine, Fig. 15 (not shown), via an engine driven valve (224). A plurality of inclined draught carburetters (196) Figs. 13 and 14 (not shown), may be arranged in two groups on the banks of a V-eight engine. Each group of four carburetters have a common throttle slide valve (166) and are formed by a common casting. The two slide valves (166) are linked to a regulator (192) of the fuel supply to the carburetter fuel bowls (149) from a pump. The carburetter inlets receive air from within a common air filter (151). The Specification includes theory of formation of the shock waves and specifies that the suction produced at the fuel outlet by the shock wave is substantially greater than the suction effect due to the flow of air through the induction passage.

Abstract: 684,984. Latches. GILL, W. A., and WHISTLECROFT, A. W. Oct. 11, 1951 [July 13, 1950], No. 17546/50. Class 44 A door latch comprises a body 1, Figs. 1 and 2, having parallel bores 3, 4, a spring shot latch bolt 6 slidable in the bore 4, an auxiliary bolt 5 slidable in the bore 3 adapted to control the position of a locking member 17 and a ball 11 movable in a bore 10 interconnecting the bores 3, 4 adapted to engage selectively in grooves 6b, 17a in the latch bolt and locking member respectively, the latch bolt has a roller 12 pivoted in a slot in the nose and its movement is limited by a stop 9 engaged in a slot 6a. A spring 18 bears between the bolt 5 and the locking member 17 and a second spring 16 bears between the locking member and a large steel ball 15 which is engaged in a U-shaped cam notch in a rod 8 slidable in a cross-bore 7 in the body 1 and having a handle for moving it. The striking plate 20, Fig. 4, has an opening 13 to receive the roller ended bolt 6 and a chamfered edge portion 21 to delay the inward movement of the bolt 5 when the door is shut. Fig. 1 shows the door-open position of the parts. When the door closes the bolt 6 is driven in by the engagement of its roller by the edge of the striking plate, the ball 11 being displaced into the groove 17a to hold the locking member 17. The auxiliary bolt 5 is then pressed in by the striking plate, the spring 18 being compressed. When the bolt 6 registers with its opening 13 it moves out again, releasing the locking member which is then displaced by the spring 18 to a position where it abuts the ball 15 and in which the ball 11 is blocked in locking position in the groove 6b by a solid part of the locking member 17 (see Fig. 2) To release the bolt 6 the rod 8 is displaced to move the ball 15 and the locking member 17 outwards to the position where the groove 17a registers with the bore 10 and receives the ball 11. Further pull on the handle causes the roller 12 to roll out of the opening 13 and retract the bolt 6. The Provisional Specification describes a method of operating the lock electrically, the movement of the sliding rod 8 being controlled by the armature of a solenoid. In another arrangement the striking plate is fitted with a movable portion controlled by a solenoid adapted to be displaced to release the auxiliary bolt. In this form the rod 8 and ball 15 are omitted, the spring 16 bearing on a blank end of the bore 3.

Filed: 1956-06-07
Abstract: 815,118. Beam controlling devices. PICKER X-RAY CORPORATION WAITE MANUFACTURING DIVISION Inc. June 7, 1956, No. 17592/56. Class 98(1) A beam controlling device for high energy rays includes a housing, a plurality of adjustable diaphragms mounted on a common axis in the housing to provide a raypassage therethrough, each of the diaphragms comprising a plurality of members forming a closed boundary, the members including a pair of ray absorbing bars mounted in a common plane and movable towards and away from one another, and control means for positioning simultaneously the movable bars of at least some of the diaphragms so that their edges adjacent the ray passage are maintained aligned in two planes as the angle between the planes is changed. As shown, rays from a source 19 in a housing rotatably mounted on the yoke 12 by trunnions 13 and in the form of a steel encased lead wheel 16 bounded by a lead cylinder 10, pass through a conical passage 22 into the beam controlling device which comprises a first set of diaphragms each of which consists of a pair of parallel fixed bars such as 29a (Fig. 6) upon which slide a pair of movable parallel bars A5, and a second set of diaphragms interleaving with the first set and each having fixed bars such as 29b disposed perpendicular to the fixed bars 29a of the adjacent diaphragm, and carrying slidable parallel bars B5. Pairs of adjacent diaphragms thus form rectangular apertures with both sides variable, and the first set of movable bars A1-A11 lie with their innermost edges in a pair of common planes which can be varied from the position X (Fig. 4) to the position Y; the inner edges of the movable bars of the second set lie in a second pair of variable planes such as to provide in effect a hollow pyramid-with variable sides and apex fixed at the source-which controls the beam. Each set of bars is movable independently of the other by means of a pair of tie plates coupled with the bars and controlled by cam means for holding the plates in the various adjusted positions. Each diaphragm bar is steel covered; the lateral widths of the bars decrease in the direction away from the source, and the movable bars have a lateral width not greater than distance from the outer edge of the largest pyramid to the housing. Pairs of light beam projectors are included to locate the patient at the correct distance from the apparatus, and means are included for the attachment of compression applicators.

Title: Improvements in or relating to structural elements for turbo-machines such as compressors or turbines of gas-turbine engines
Inventor: KENT NELSON HECTOR
IPC: F23R3/60
Filed: 1952-07-11
Abstract: 728,670. Turbines and compressors. ROLLSROYCE, Ltd. June 30, 1953 [July 11, 1952], No. 17625/52. Addition to 695,724. Classes 110 (1) and 110 (3). In a turbine or compressor, for example of a gas turbine engine, the casing comprises a pair of concentric shells spaced apart radially, radially-aligned slots being formed in the shells through which an end of each blade is passed, the blade being retained in position by means of a radially-facing shoulder which abuts one surface of one of the shells and by mechanical abutment means which co-operate with the blade and with an oppositely-facing surface of a shell. The casing of an axial-flow compressor shown in Fig. 1 comprises an outer wall 10 and an inner sheet-metal shell 11, which constitutes the outer surface of the working-fluid passage, and a second shell 12 disposed therebetween. Radially-aligned slots are formed in the shells 11, 12 and the ends of the blades 13 which are formed with shoulders 13a are passed therethrough. The lugs or tangs 14 formed at the ends of the blades by the inclined slots 14a are then bent to engage the shell 12. The shoulders 13a may engage either the inner shell 11 or the outer shell 12, and the tangs may alternatively be formed by slotting at the centre of the radially outer end of the blade. In Fig. 4 the ends of the blades are formed with notches 15 which are engaged by a locking member 16 retained in position by a spacer strip 17 tackwelded at 18 to the shell 12. The strip 17 serves to retain the locking members 16 of two adjacent rows of blades. In a further embodiment, the radially-outer ends of the blades are formed with closed slots which lie radially outwardly of the outer shell 12, a locking strip or wire being threaded through the slots. The radially-inner ends of the blades may carry flanged sheet metal members to provide seals with adjacent rotor structure, the members being threaded over the blades and secured to retaining strips engaging notches in the blades.

Filed: 1974-04-23
Abstract: 1472599 Cleaning heat exchangers H WIEDERHOLD 23 April 1974 [25 April 1973] 17640/74 Heading F2N A heat exchanger incorporating an internal cleaning arrangement that may be used while the exchanger is operative comprises an array of pipes 2 and a drive (not shown) to move closefitting hollow cylindrical scrapers 8, whose length excedes their maximum transverse dimension, along the pipes when they are to be cleaned. The pipes 2 are held by plates 3 and 3<SP>1</SP> with their ends open to spaces 5 and 6. Steam flows into and out of the space 4 between the plates via pipes (not shown) to heat a fluid, e.g. a paint solvent which itself flows into space 5, through the pipes 2 and out via a pipe 7. The drive is a pneumatically-operated piston and cylinder arrangement whose motion is transferred simultaneously to each of the scrapers 8 by the rods 12 and 9 and the plate 10; the travel is sufficient to cover the entire length of the pipes. The scrapers are in the form of hollow cylinders 8a connected by struts 8b to the rods 9, the cross-sectional area of a scraper being less than that of the associated pipe. In an alternative arrangement (Fig. 3, not shown) three scrapers are fitted to each rod 9 so that the travel may be reduced to <SP>1</SP>/ 3  of the pipelength. Another design of scraper (Fig. 4b, not shown) consists of a cylinder with a number of holes bored longitudinally through it. Hydraulic or mechanical drives may be used.
