Filed: 1970-08-20
Abstract: 1327441 Making pipe couplings RAYCHEM CORP 20 Aug 1970 [25 Aug 1969] 40138/70 Heading B3A [Also in Divisions B1 C2 and F2] A method of making a tubular coupling of a memory metal (as defined in the Specification) comprises deforming a hollow article made of memory metal at below the critical temperature. Secondary deformation may be given either by deforming below the critical temperature with a force greater than that necessary to impart maximum thermally recoverable deformation, or alternatively by heating to the critical temperature at least and restraining complete recovery by allowing the article to contract about an object having a dimension greater than that to which the article would have otherwise contracted. This object may be a keeper of the same material, of resilient material, of copper-beryllium and/or of a material having a netative coefficient of expansion. The article may be in the form of a coupling for pipes, and of such dimensions that upon heating to at least the critical temperature the coupling will contract and grip the ends of the pipes to be joined. (see Division F2). Such a coupling (see e.g. Fig. 1) may be made from stock by drilling a hole therein, turning and cutting off the blank. The tapered end portion 26 is formed on a lathe. The lathe taper attachment is then reset to make the radial cut 30. By repeating, a second taper and tooth (32) are formed. The process is repeated from the other end, and finally the central portion 24 is bored. Thereafter taper portions 14 and 16 may be formed on the outside. Before use the surfaces should be polished and de-burred, and the coupling should be annealed.

Abstract: 1,158,905. Measuring thickness electrically. COURTAULDS Ltd. Nov. 1, 1966 [Sept.23, 1965], No.40623/65. Heading G1N. [Also in Division H1] The denier of a yarn is measured by comparing the capacities of two substantially identical capacitors, between the plates of one of which the yarn travels. In the embodiment, one plate of each capacitor is formed by depositing a layer of metal and a guard ring on a common quartz plate or block, the other metal plate, which is common to both capacitors, is arranged to face that side of the quartz block on which the metal layers are deposited, and is spaced from the quartz block by a quartz spacing piece. Alternatively the common metal plate may be replaced by two identical metal plates connected together which may be identical to the deposited plates. Preferably the deposited plates are formed by evaporating a continuous layer of metal on to the block and then removing excess metal by chemical means, to isolate the plates and form the guard rings. In the measurement of yarn denier, the two guarded plates are connected to opposite ends of the secondary winding of a transformer which is centre tapped to earth and to the common plate or to the other two plates which are connected together. The current flowing between the common plate and earth is measured to give an indication of the denier of the yarn.

A planetary gear set 38 consists of a sun 36 on driving member 34, a planet carrier 58 carrying gear-wheels 62, and an annular gear 64 that can rotate in one direction only. Carrier 58 is rigidly connected to the driven clutch member 46. There is a second planetary gear set 68. In operation the tool operates until at a predetermined torque, dependent on the setting of spring 54, clutch member 40 is forced away from member 46. After a set movement port 114 is opened to allow pressure fluid to act on surface 112 and move the piston and thus member 46 is in disengaged position. When the clutch members are engaged drive from spindle 34 to spindle 66 is in a one to one relationship. Disengagement of the clutch members puts the drive through the planetary gear set 38 with a consequent reduction in speed. In an alternative embodiment where a number of tools are assembled in a multi-spindle machine the inlet port to chamber 110 is positioned as at 130 in Fig. 3. In operation the clutch members are not forced apart but each tool operates until it stalls.

Abstract: 1,198,504. Ratchet clutches. TORRINGTON CO. 8 Sept., 1967 [12 Sept., 1966], No. 41044/67. Heading F2C. To disengage and positively brake the driven member of a jamming-roller clutch to provide accurate indexing thereof, the rollers 20 in a one-way overrunning clutch are mounted between driving and driven races 16, 18 in the windows of the usual cage 21 rotating with the driven race 18, and in the windows of a second cage-like release sleeve 22 positioned freely within the clutch and provided with a pair of diametrically opposite tabs (38), Fig. 5 (not shown), abutment of either of which with a stop, prevents rotation of the release sleeve, the rollers 20 being moved down the jamming ramps on the driven race 18 to disengage the clutch and the cage cross-bars abutting the rollers to positively brake the outer race 18. The rollers 20 are spring-biased relative to the cage 21 into the jamming ramps. Again, Figs. 6-8 (not shown), the inner race is driven, the release sleeve (48) being formed radially outside the cage (56), and its tabs being turned radially inwards. Again, Figs. 9-13 (not shown), a two-way clutch has pairs of rollers (73) associated with pairs of adjacent ramps (82), (83) on an outer driven member (77), the cross-bars of the cage (75) passing between the rollers of each pair and spring-biasing them toward their respective ramp, and the cross-bars (95) of the release sleeve (76) extend between the pairs of rollers. Abutment of the tabs (100) on the release sleeve (76) with a stop in either direction urges the operative rollers from their ramps to disengage the clutch and again brake the driven member. Overrunning of the clutch in both directions is prevented by the abutment of the non-operative rollers with their ramps.
