Title: Device for controlling movement between two relatively movable objects
Inventor: TREVASKIS HENRY WILLIAM
IPC: F16H21/06
Filed: 1958-12-11
Abstract: 931,777. Building tyres. DUNLOP RUBBER CO. Ltd. Nov. 30, 1959 [Dec. 11, 1958], No. 39975/58. Class 144 (1). [Also in Group XXIV] Relative stepwise movements increasing in magnitude between limits, in a selected direction, between relative reciprocable or rotatable members 1, 3, for example, in a tyre manufacturing process described in Specification 908,118 [Group XXXIV], are controlled by a jointed link 13, pivoted on one member 1 and engaging steps 9 on the other member 3, the link being caused to partly open and close between successive steps, whereby each step is greater than the preceding step. Initially the member 3 is biased by a spring 11 rightwards against a stop 2. Movement of the member 3 in the selected direction, i.e. leftwards, causes a nose 17 of the jointed link 13 to engage the lowest step of the member 3, whereupon the link parts 13 are turned in a closing direction about their common pivot 15 against a spring 20 until link-faces 19 abut to stop the motion. To make a further step, the member 1 is returned rightwards by the spring 11, and link spring 20 opens the links 13 to abut faces 18. The left-hand link 13 itself is frictionally held at 16 undeflected by this opening movement, so that on the next leftward movement of the member 3, the nose 17 of the link obstructs the next higher step 9, permitting a longer stroke, each subsequent stroke causing a similar step up. Three link and step assemblies are equally spaced around the members 1, 3 which are cylindrical and are prevented from relative rotation by a pin 6 in the member 3 engaging a key-way 5 in the member 1.

Abstract: 1319276 Moulding spirals BIELOMATIK LEUZE & CO KG 1 Sept 1970 [2 Sept 1969] 41757/70 Heading B5A [Also in Division B6] In the formation of a thermoplastics spiral for screwing into holes in a pad of shorthand sheets, a thermoplastics thread 15 is fed at 16 into a heated housing 19 along an internal spiral groove whereof it is conveyed, during heating to plasticizing temperature, by contact with a continuously rotating cylindrical drum 17, which delivers it at 12 to a rotating mandrel 26  around which it is intermittently advanced by a stationary helical thread guide coil 27, the initial portion 29 of the mandrel and helical coil being heated within the housing 19 to form the spiral, which is set during further advance along a portion 30 of the mandrel and helical coil extending through a cooling chamber 31 and from which it is intermittently delivered and screwed into a pad hole, cut and then bent to prevent unscrewing from the pad. The housing 19 is heated to the plasticizing temperature by elements 23 extending therealong, and the initial exterior portion thereof is provided with cooling fins to ensure gradual uniform heating of the thread 15. The helical thread coil is supported by diametrically opposed axially extending bars which, through the cooling chamber 31, also ensure circulation through the coil of water, via an inlet 32 and screen 34, to an outlet 33. The mandrel 26 is intermittently driven from a braking motor, and the depth of the helical thread coil and a widened end of the mandrel 26 permits the thermoplastics spiral, if obstructed during delivery into the pad hole, to rise out of driving engagement with the mandrel 26. The drum 17 continuously rotates, and is of a diameter to permit the thread 15 to rise out of driving engagement therewith during the intermittent stoppages of the mandrel 26. In starting up the apparatus, a thread 15 is urged into driving contact with the drum 17 by a roller 21 pivotally brought into action, the emergent thread end at 12, at which is located a hinged transparent operation cover 25, being welded to the end of a thread wound along the  mandrel 26 by rotation thereof in its reverse  direction. The helical thread guide coil 27 is preferably discontinuous intermediate the housing 11 and cooling chamber 31 to reduce conduction.
