Title: Forming transverse corrugations in a tubular blank
IPC: B21D15/06
Filed: 1972-03-18
Abstract: 1370700 Corrugating tubes GENERAL MOTORS Ltd 15 Feb 1973 [18 March 1972] 12778/72 Heading B3E Transverse corrugations are formed in a tubular blank 44, e.g. for a jacket for a collapsible steering shaft on a vehicle, by registering the blank on a collapsible segmental mandrel 10 and passing it through a die assembly 12 comprising a ring of toothed wheels 14 rotatably mounted on a common holder 16 with their axes disposed in a common radial plane, and therafter collap-  sing the mandrel to permit removal of the corrugated blank. As shown, the mandrel comprises eight corrugated segments 20 surrounding a plug 22 slidable in a bush 26 in a fixed housing 24, the segments having flanges 32 radially movable in a groove 34 in the housing, and being urged together by a spring retainer 30. The plug has larger and smaller diameter portions 28 and 36, which are alternatively locatable within the segments to impart an extended and a collapsed configuration to the mandrel. Eight wheels 14 are mounted in the holder 16, each registering with a mandrel segment 20, and the wheel teeth have concave crests matching the convex crests on the mandrel segment corrugations 18. Spring ball detents 40 index the wheels prior to engagement of the wheels with the segments when the assembly 12 is moved up over the blank (through the blank may be moved through the assembly). Prior to corrugating, a tubular blank may have its end portions reduced in diameter to provide portions on which bearings or tube extensions are to be fitted, these end portions being connected by shoulders to a central larger diameter portion to be corrugated. The blank is placed over the collapsed mandrel which is then expanded within the central portion. The resulting corrugated tube has longitudinal ribs corresponding to the gaps between adjacent wheels and between adjacent mandrel segments when expanded. The wheels 14 may be movable together radially of the holder during corrugating, e.g. by a cam mechanism, to vary the characteristics of the corrugations.

Title: Improvements relating to liquid fuel injection pumps for internal combustion engines
IPC: F02D1/12
Filed: 1946-04-29
Abstract: 611,437. Starting oil engines. C.A.V. Ltd., BROOK, K., and NICOLLS, W. E. W. April 29, 1946, No. 12807. [Class 7 (iii)] A liquid fuel injection pump has means whereby the control member can on stopping be moved beyond its normal fuel cut-off position to operate means enabling an excess of fuel to be supplied when starting. In Fig. 1, the control member b, resiliently connected to a hydraulic governor c, is shown in its normal cut-off position, and the maximum pump delivery is limited by a stop-plate f co-acting with a stop j depending from the member b. At stopping, the member is further displaced to the right to lift the plate f until a spring catch m retains it. At starting, the stop can enter a hole g in the plate, thus allowing the member b to provide excess fuel. The stop lifts the catch m so that the plate f is returned to its normal position by a spring s acting on the lever k when the member b is moved by the governor c to its operative position after starting. In a modification, the plate f is dispensed with, the stop j co-acting with a hole g in a bent part of the lever k, which also coacts with the catch m. In Fig. 8 the maximum pump delivery is normally limited by a stop 3 co-acting with a stop v on a lever v<1> rotatably mounted on an arm i attached to the control member b. A spring-pressed pin x extending through bores y and w in the arm i and lever v<1> is normally situated as shown, but when the member b is moved back beyond its cut-off position, a stop 2 rotates lever v<1> against a spring until it is horizontal, the pin-head x<1> then projecting into the bore y to retain the lever in this position. The stop 3 now co-acts with the pin x so that the member b can be moved for starting beyond its normal maximum position, the head x<1> being forced out of the bore y so that the lever v<1> can be returned by its spring to its normal inclined position when b is retracted after starting.

Filed: 1933-05-03
Abstract: 416,737. Pressure gauges. ARCUS, C. R., 152, Browning Road, East Ham, London. May 3, 1933, No. 12833. [Class 106 (ii).] A mounting for a gauge is provided with two non-return valves and a liquid column between the inlet and the gauge proper together with a release valve in the space between the first two valves. The connection a fits the usual indicator cock and leads to a non- return valve b which may be turned by a spindle c. A passage d leads to a valve box containing a release valve l the box being enlarged at the lower end to form a chamber e filled with oil and a valve f held up to its seating by a spring. A passage g forms with the chamber e a U-tube and leads to the gauge h which may be of Bourdon type. In use, the release valve is closed and the gas valve b opened. After a few strokes of the engine, the gauge stands at the maximum pressure. To release the pressure fluid, the spindle k is operated to open the valve l and by the extension m to open the valve f. A groove k in the spindle allows escape of the gas or fluid. The groove collar m serves to damp the movements of fluid and arrest particles of solid matter. An air vessel may be fitted to the passage d and is advisable in the case of liquid pressures. The valve b is rotatable by a tongue on the spindle engaging a groove on the valve or the latter may be fitted with vanes on which the gases act to rotate the valve. The passage to the tester is an addition to the volume of the chamber under test and compensation may be effected by the amount of projectors of the fitting into the cylinder or chamber.

Title: Improvements in fluid dispensing apparatuses for dental engines
IPC: A61C1/00
Filed: 1959-04-17
Abstract: 853,639. Dental engines. ATLAS COPCO A. B. April 17, 1959 [April 21, 1958], No. 13151/59. Class 81 (2) Dental equipment using an air driven turbine has a supply of liquid fed to the handpiece and pressure for supplying the liquid is applied only when the handpiece is in use. The main air supply is received through a pipe 8, Fig, 4, and is passed through a pressure reducing valve 4 and check valve assembly to the handpiece 3. As described in Specification 853,638 air is only passed to the handpiece when this has been raised from the pivoted rest 7 and a plunger 14 has consequently actuated the valve assembly 5. A branch pipe 35 leads to the liquid supply device where it enters through a duct 36, Fig. 2, leading to a pressure reducing valve 24 controlled by a diaphragm 28, loaded by an adjustable spring 31. A duct 39 leads the air to a valve 43 which is normally closed by a spring 54. However, as soon as the air supply to the handpiece commences to flow, the resultant drop in pressure in the regulator 4, Fig. 4, actuates a microswitch 18, which causes energisation of a coil 55, Fig. 2, and this draws back the plunger 44, so as to open a valve 43 and seal the orifice 50. Air, at reduced pressure, thereupon flows through duct 45 into the upper part 46 of a container 57 holding a supply of distilled water. This causes water to be forced up the pipe 63 to outlet 66 and air to pass through a pipe 70, both being led to an adjustable needle valve assembly 68, Fig. 4, where their proportions are determined, and they are passed on through tube 81 to a distributing valve 6 which directs them to the handpiece which is in use. When the handpiece is replaced on its rest the coil 55, Fig. 2, is de-energised and the plunger 44 moves back to close the valve 43 and open the outlet 50. This vents the pressure in the space 46 to atmosphere through a muffler 53. Specification 785,109 also is referred to.

Abstract: 424,539. Pre-payment mechanism for meters. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. May 4, 1934, No. 13502. Convention date, Feb. 2. [Class 27] Mechanism for prepaying basic charges ; price changing mechanism.-In prepayment mechanism for meters, means for collecting a basic charge comprises an escapement member intercalated in the transmission between the quantity mechanism and the commodity control member, and operated by a constant speed motor to permit periodic movement of the commodity control member under the action of a power storage device. As shown, the quantity mechanism comprises a meter driven sun-wheel 6, a coin-operated sun-wheel 7, and a planet wheel 9 ; the shaft of the planet carrier gears with a wheel 15 carrying an arm 17 having a tooth 18 which engages in the teeth of a double cog wheel 19 whose two sets of teeth are relatively staggered. The wheel 19 is fast with a pair of toothed wheels 20, 21 gearing, respectively, with a commodity controlling spindle 28, and a shaft 33 having a pinion 32 meshing with a spring-urged toothed sector 34. The toothed wheels 19-21 are free to slide on a spindle 16, and are periodically oscillated, so that tooth 18 engages alternately with the two sets of teeth, by the cranked end 23 of a shaft 24 driven by a constant speed motor. Wheels 19-21 and the commodity shaft 28 therefore move under the action of the spring-urged sector through a distance in advance of the arm 17 corresponding to the pitch of the teeth of wheel 19, for each revolution of the shaft 24. This movement of the shaft 28 is additional to that due to the meter mechanism transmitted through the arm 17. The toothed wheel 19 is replaceable by a wheel of different pitch for effecting a change in the basic change rate.
