Title: Improvements relating to electrically-driven pumps
Inventor: VALENTINE REGINALD
IPC: F04B45/027
Filed: 1955-03-25
Abstract: 794,039. Bellows pumps. COAL INDUSTRY (PATENTS) Ltd. June 18, 1956 [March 25, 1955], No. 8817/55. Classes 8(1) and 102(1). [Also in Group XXXVII] In an electrically-driven pump for gas or liquid having a solenoid 1 with an armature comprising a plunger 9 carried by a shaft 8 connected to one end to a bellows 11 and at the other to a projection or disc 16, the projection enters an opening in a member 18 which moves to effect opening or closing of electrical contacts 21a, 22 to make or break the electrical circuit of the solenoid when the projection engages the boundary of the opening thereby causing the bellows to alternately extend and collapse to draw in (through valve 13) and discharge (through valve 14) the fluid being pumped. The member 18 is pivoted at 19 and its edge forms a cam 20 in contact with a leaf spring 21 which carries the movable contact 21a. The contact assembly is mounted on a body 23 carried on a platform 24 slidable in the casing 7 and adjustable in position by nuts 25. Normally the spring 17 holds plunger 9 to the left and contacts 21a, 22 are closed. When the battery is switched on, the solenoid 1 is energized, plunger 9 moves to the right until " lost motion" is taken up and the projection 16 contacts one side of the opening in the member 18 to rotate the latter, causing the cam surface to separate the contacts and interrupt the current in the solenoid, whereupon spring 17 moves plunger 9 to the left. When the projection 16 contacts the other side of the opening in the member 18 the cam surface is rotated until the contacts 21a, 22 meet again and the cycle is repeated. A surge suppressor may be fitted (see Group XXXVII).

Abstract: 734,145. Belt gearing. INSTRUMENTS ET OUTILLAGE SOC. ANON. F.I.O. April 1, 1953 [May 7, 1952], No. 9009/53. Class 80 (1). [Also in Groups XXII and XXIII] A machine tool comprises at least one work-holder P and at least one tool-holder t and two independent cam-shafts D, E with means S for alternately actuating them, the camshafts controlling, respectively, the milling or grinding of the work-piece and the feeding of the work to the holder. A motor M rotates a belt 2, to drive either the shaft D or the shaft E, and a pulley 3 to drive an energy-storing device F, as described in Specification 734,146 and which controls the position of the belt 2 through a shifter arm 27 on a carriage 23. The arm 27 is adjustable angularly to tension the belt. When a work-piece f has been machined and ejected from the holder P, under the control of the cam-shaft E as described in Specification 734,147, [Group XXII], a cam 55 actuates a cable 53 to rotate a bracket 50, Fig. 8, carrying a pawl 44. The pawl 44 releases a second pawl 36 from the beltcarriage 23 to allow the device F to move the belt to drive the shaft D. The carriage is then held in position by a second pair of pawls. The retaining pawls 44 are released from the pawls 36, when non-operative, by adjustable stops on the carriage.

Title: Method of making seamless rubber girdles
IPC: A41C1/04
Filed: 1963-03-06
Abstract: A method of applying a stretchable fabric lining to a seamless rubber (defined) girdle sheath comprises positioning the rubber sheath on the inside surface of an open ended hollow form, mounting the fabric lining sleeve upon an inflatable bladder, applying a layer of suitable adhesive to at least one of the joining surfaces, inserting the bladder into the hollow form and inflating the bladder (e.g. by compressed air) to press the fabric sleeve into adhesive contact with the sheath.  Three alternative procedures may then be followed:-(1) The whole apparatus with the bladder in the expanded form may be placed in an oven to cure the adhesive after which the bladder and form are separated and the lined sheath stripped off, (2) After partially setting the adhesive by air drying or heating, the bladder is deflated and removed and the hollow form and the composite article are placed in the curing oven, or (3) The sheath with the bonded lining may be stripped (methods described) from the hollow form, and may be carried by the bladder during the curing process.  The rubber sheath may be provided with perforations before and after applying the lining.  Specification 957,759 is referred to.

Title: Improvements in or relating to devices for testing gears, particularly helical gears
IPC: G01B5/20
Filed: 1941-07-18
Abstract: 548,446. Gauging toothed gears. ERNST, D. July 18, 1941, No. 9126. Convention date, Sept. 19, 1940. [Class 106 (ii)] For examining the helix, the gear and a coaxial cylinder are held while a straight-edge element engaging the cylinder and a feeler engaging a gear tooth and operating a recording device are moved tangentially to the cylinder and parallel to the common axis, whereas for tooth contour, the feeler and straight-edge are at rest and the gear and cylinder moved parallel with the straight edge. The base 1 is provided with horizontal and vertical guides 2, 3. The horizontal guide 2 has a slide 5 moved by a screwed spindle 4 and carrying a track 6 for a transverse slide 7 moved by a screwed spindle 8. In a sleeve 9 of the slide 7 is a rotatable mounting mandrel 10 for the gear 11 to be tested the mandrel having also fixed to it a rolling cylinder 13. A slide 14 movable by a screwed spindle 16 over the vertical guide 3 carries a table 15, a feeler 17 and recording means 19, 20. The feeler 17 contacts the tooth flank to be examined and movement of the feeler is transmitted by multiplying leverage 18 to a scriber 19 recording on a drum 21 rotated by a cord 24 passing over a sheave 23. A straight-edge 25 frictionally engages the cylinder 13 under the constant pressure of a spring 27 acting on spindle 4. An arm 26 of the base 1 has a guide 261 in which the straight-edge 25 slides. The movement of the straight-edge 25 is controlled by a guide groove 28 in a disc 30 which is engaged by a member 29 on the part 25. The disc is rotatable and fixable in a holder 31 integral with the table 15. The diameter of the cylinder 13 is equal to that of the base circle of the helical gear 11 and when the slide 7 is moved parallel with the rule or straight-edge 25 the contacting point of the feeler 17 which is vertically above the edge of the rule describes an involate curve coinciding with the contour of the tooth. Deviations are transmitted to the feeler 17 and hence to the scriber 19 and are recorded on the paper on the drum 20 which is moved by attaching the cord 24 to the slide 7. To examine the helix, the disc 30 is set to the correct helix angle and the spindle 16 rotated, the cord 24 being attached to the base 1.

Abstract: 831,176. Change-speed friction gear. EASY WASHING MACHINE CO. Ltd. March 25, 1958, No. 9617/58. Class 80 (2). The rim 17 of a gramophone turntable 1 is driven from a stepped motor spindle 11 through a friction idler disc 16 rotating upon a shaft 19 carried by an arm 18, pivoting upon an idler support 21 fast with a rotatable pin 22 moved axially to establish a ratio shift by turning a knob 30 fast with a cam body 25 having a stepped cam 26 engaged by the end of the pin, the cam body also having a series of cam recesses 32 . . . 36 engaged by the end 39 of a lever 38 pivoted about a stud 37 on a supporting frame and engaging at its other end an arm 41 depending from the idler support 21, the arrangement being such that on turning the knob 30, the cam recesses 32 . . . 36 act to turn the lever 38 which, through the arm 41, pivots the idler support 21 and withdraws the friction idler disc from the stepped motor shaft, the stepped cam 26 then effecting axial movement of the pin 22 to position the idler disc opposite a new step on the motor spindle 11. The friction idler disc 16 is normally biased to engage the motor spindle 11 and the turntable rim 17 by a spring 24, and the lever 38 is biased to engage its end 39 in the cam recesses 32 ... 36 by a spring 42. A spring 28 surrounds the pin 22 and biases it to engage the stepped cam 26. The cam recess 34 is of lesser depth than the adjacent recesses, so that when the end 39 of the lever 38 engages therein, the idler disc 16 is held away from both the motor spindle 11 and the turntable rim 17, corresponding to a neutral position of the gear. The friction idler disc 16 is held upon its supporting shaft 19 by a C-spring allowing axial adjustment of the idler disc to compensate for variations in manufacturing tolerances.
