Title: Improvements in or relating to motion translating device
IPC: F16F1/02
Filed: 1951-08-23
Abstract: 700,213. Press button switches; thermal switches. BURCH, L. W., and BURCH, H. K. Aug. 23,1951 [Nov. 29, 1950], No. 19889/51. Class 38(5) [Also in Group XXXII] A spring E (see Group XXXII) comprising at least one elongated strip 40 of resilient material of high width to thickness ratio, and having integral tension members 45, 46 has an arm 90 carrying a switch contact 91. The member 46 is riveted to a boss 74 formed in the body 71 of the switch. The member 45 is riveted to a tongue 72 integral with the body 71. After assembly the tongue 72 is slightly depressed below the level of the member 46. This has the effect of producing a slight separation of the members 45, 46 which results in the spring warping into one of two stable positions of equilibrium. In this position, the contact 91 engages a contact 82 carried by, and insulated from, the switch body 71. Load applied at P by a pin 92 mounted on a leaf spring 93 (Fig. 18) carried by the switch cover 94, will .result in the spring snapping over to its other position of equilibrium. As applied to a rod-and-tube type thermostat, Figs. 23, 24 (not shown), the member 45 is connected to the free end of the rod and the member 46 is rigid with the thermostat housing. Differential expansion thus results in tension occurring between the members 45 and 46, and thus causes the arm 90 to move into contact making (or breaking) position.

Title: Submarine pipelines
IPC: F16L1/14
Filed: 1976-03-14
Abstract: 1525669 Laying submerged pipes C G DORIS 14 May 1976 [15 May 1975] 19907/76 Heading F2P In a method of laying a sub-aqueous pipeline, a pipe portion T is hauled by a traction line 4 from an on-shore location where pipe sections are successively added, via an elongate force distribution member, 5, which extends over the full length of the pipeline and is attached thereto at points spaced along its length. In a preferred embodiment, a pipe T is suspended above a distribution cable 5 (of, e.g. wire cable, rod or rods connected by cable or chain) via buoyancy means (not shown) and connected thereto via a plurality of spaced hangers 6 (formed of metal cable, chain or as preferred plastics) secured to respective metal collars of the pipe and cable via loop formations. The cable and hangers may be of sufficient weight alone to overcome the positive buoyancy applied to the pipe or alternatively, weighting means, e.g. steel or cement blocks may be threaded on the cable. The weights may be supplemented by anti-drift devices, e.g. chains suspended at intervals from the pipe or by arrangements threaded on the cable at intervals there along offering low resistance to movement in the pipe laying direction but providing constraint against lateral movement of the pipe. The devices may take the form of anchor blocks (Figs. 14-21, not shown) which have relatively smooth lower surfaces for contacting the water bed, but which are adapted via lateral projections to engage the bed upon rolling of the block which is induced by lateral movement of the pipeline to which the blocks are secured, or alternatively, may take the form of box arrangements (Figs. 22-24, not shown) adapted for movement on the pipe axis direction via wheels which are formed with radial metal spikes or as disc formations to offer resistance to lateral movement.

Abstract: 1,112,610. Buckle threading machines. UNITED ELASTIC CORPORATION. 6 May, 1966 [19 May, 1965], No. 20078/66. Heading E2A. In a machine for inserting fabric webbing through a slot in an article, such as a hose suspender grip 10, the article is fed from a loading station by a pusher 11 into a recess in a rotary table 2. The table is indexed round until the article reaches a second station where a predetermined length of webbing 19 is fed over the top of the slot, by a reciprocating gripper, and then pushed through the slot by an inserting member 30 whilst the remaining webbing is held by a clamp 27. After the member 30 has been withdrawn the inserted webbing is folded back parallel with the remainder of the webbing by a cam operated folding finger 36. The folded webbing is then severed by a cutter 41 and the assembly is then indexed round to a third station over an unloading compartment 57 into which it is thrust by downward movement of a rod 52, succeeding assemblies being held together by a spring (56, Fig. 6 not shown) and prevented from rising against the table 2 by fingers (53). When a predetermined number of assemblies, e.g. twelve have been fed into the unloading compartment 57 the machine is stopped and the bundle of assemblies removed by hand. The indexing of the table is carried out by a single toothed gear which engages a 12-toothed gear attached to the table. The pusher 11, inserting member 30, cutter 41, rod 52, folding finger 36, clamp 27 and the feed means for the webbing 19 are operated in synchronism with the table 2 by cams. In other embodiments all or part of the movements may be produced by a Geneva movement or electrical means. The means for feeding the webbing over the slot comprises a member (22, Fig. 2) on a cam operated bell crank (23). The amount of webbing which is fed during each operation is controlled by screws (26). The articles may be placed into the loading station by hand or fed automatically from a hopper.

Abstract: 740,416. Windscreen cleaners. LETHBRIDGE, W. REED-. July 21, 1953 [July 28, 1952], No. 20273/53. Class 138(1) In a rotary windscreen wiper, wiper blades rotatable about the axis of a support or head are urged towards the surface of a windscreen by centrifugal action and means are provided to limit the pressure of the blades on the windscreen. In the embodiment of Figs. 1 and 2 the wiper head 7 is rotatably and slidably supported on the windscreen 5 by a rubber button 8 against the urge of a spring 4. A rod 1, pivoted at 6 to the head extends on either side of the head and in the embodiment shown the portions of the rod on either side of the head are of unequal lengths so that the wiper blades 2, 3, will wipe over inner and outer tracks on the windscreen which tracks may overlie if desired. When it is desired that the blades shall wipe over a common track the portions of the rod 1 on either side of the support will be of equal lengths. The blade 3 is pivotally mounted at 22 in a U-shaped support 21 carried by the rod 1 whilst the blade 2 is pivoted between the arms of a stirrup-shaped link 9, at 12, the closed end of the stirrup being pivoted, at 10, to the rod 1. The stirrup 9 and the blade 2 are urged towards the rod 1 by a spring 13 on' the rod acting between the stirrup and the inside' end portion of a stop collar 15 screwed on to the rod. The collar and spring constitute a presetting and adjusting means for limiting the pressure of the blades 2, 3, on the windscreen. After adjusting the position of the collar 15 on the rod it is locked by a nut 14. A weight 20 is secured to the end of the shorter portion of the rod 1 to counterbalance the greater weight of the longer portion of the rod together with its blade 2 and the presetting and adjusting means. When the head 7 is rotated, by a motor through a flexible or other drive means detachably connected to the head, the, blade 2 and stirrup 9 are flung outwardly: as shown in Fig. 2, to cause the stirrup to pivot on the rod, and compress the spring 13 and thus urge the blade 2 against the windscreen. The blade 3 is also urged against the windscreen owing to the. rod' 1 pivoting on the head 7 and the pressure of the blades 2, 3 on the windscreen is limited by the closed end of the stirrup abutting the collar 15. In the embodiment of Fig. 4, the stirrup 9 has an extension 18 beyond the pivot 10 and the spring 13 is connected to the end of the rod 1 and to a screw 19 engaging in the extension 18. The movement of the blade 2 away from the rod will. be limited by the end of the screw engaging the upper side of the rod 1. Two other embodiments are described; in one the spring is connected between the stirrup and the lock nut for the collar, whilst in the other a compression spring is provided between the stirrup and a point of the rod 1 between the pivot 10 and the wiper head 7. Specification 593,246 is referred to.
