Patent GB-1287888-A (GB)
IPC: F16C11/06
Filed: 1968-11-18
Abstract: 1287888 Universal joint AUTOMOTIVE PRODUCTS CO Ltd 7 Nov 1969 [18 Nov 1968] 54625/68 Heading E2F A universal joint includes a component engaged with a surface of a recess in a first member and having a knife edge engaging a flat surface of a second member, and an annular shroud fixed to the first member and engaging a convex surface of the second member for universal movement, the shroud axis extending laterally of the first member and passing through the centre of the knife edge, angular movement of the first member relative to the component being permitted only about an axis normal to the knife edge and the shroud axis. In one embodiment, Fig. 4, a component 17 has part-spherical surface 18 engaging a similar surface in recess 16 of member 10, and has a diametral knife edge 31 engaging flat surface 23 of member 24. Shroud 27 has a part-spherical surface engaging a part-spherical surface 26 of member 24. Knife edge 31 is held at right angles to the longitudinal axis of member 10 by two sideby-side pins 22, mounted in member 10, which engage in two component slots 21 which are elongated in the knife edge direction. Cooperation of the pin and slots serves to prevent angular movement of member 10 relative to component 17 other than about the longitudinal axis of member 10. In a second embodiment, Fig. 6, angular movement of member 10 relative to component 32 is similarly limited by the engagement of component flats 33 with two opposed flat sides of the aperture in disc 35 fixed to member 10, the clearance between component shoulders 34 and disc 35 permitting the angular movement of member 10 about its longitudinal axis. In a modification, the component has a rectangular cross-sectional shape, and passes through a similarly shaped disc aperture, the relative dimensions of the component and aperture allowing the angular movement of the member 10 about its longitudinal axis.

Abstract: 1290033 Recording/playback apparatus MOTOROLA Inc 23 Nov 1970 [29 Dec 1969] 55503/70 Heading G5R The lateral position of a head 12 relative to a multi-track tape (not shown) is indicated visually on a panel 30 by a light guide system, e.g. as shown, in which a lever 23 moves with the head and so causes a lamp 27 and an aperture 26 to move relative to four appropriately placed light guides 31-34. The lamp operates either when a cartridge 38 moves a spring member 42 from the dotted to the full line position, thereby operating a microswitch (not shown) in the lamp circuit and also moving a slot 45 into alignment with the ends of the guides, or when a stereo radio circuit (not detailed) is used. A stereo guide 35 functions irrespective of the aperture 26 and slot 45. In a second embodiment, Fig. 3 (not shown), the lamp is mounted on a lever (51) and insertion of the cartridge causes the lever to move the lamp from a position adjacent the stereo guide 35 to a position near the track guides 31-34. In a third embodiment, Fig. 4, not shown, a single guide (64) is used, the guide being pivoted for rotational movement in accordance with the lateral movement of the head 12 and associated lever 23.

Title: Hammer with a ram control device
IPC: B21J7/46
Filed: 1970-09-08
Abstract: 1309859 Hammers LANGENSTEIN & SCHEMANN AG 8 Sept 1970 42854/70 Heading B3H The ram 2 of an hydraulically operated hammer is brought to rest on its return stroke by passing the fluid from the cylinder for the ram 2 into a reservoir 22 and then into an hydraulic fluid cavity 12. During the upward movement of the ram 2, fluid is transferred from the upper end 5 of the cylinder, through conduits 17, 18, a valve 10, a valve 19, conduits 27, Fig. 2, and 21 and into the reservoir 22. A throttle 28 in the conduit 27 causes the fluid to flow into a conduit 27a, through an adjustable throttle 29 formed in a tube 39a and into a cavity 30 to raise a piston 34 which is biased downwardly by a spring or compressed air supplied through a line 35a. Fluid is also transferred from the cavity 30 into the reservoir 22 via an adjustable throttle 32 formed in a tube 31a. An actuator 38 is engaged by the rising piston 34 whereupon the valve 19 is moved to block the flow of fluid into the reservoir 22. The fluid is now forced through conduits 17, 23 and non-return valve 24 into the fluid cavity 12, pressurized by a piston 15, so that the ram 2 is brought to rest. The higher the recoil speed of the ram 2, the earlier is the actuator 38 engaged by the quicker moving piston 34. When a very high pressure is produced in the conduit 27, air pressure in a cavity 42 is overcome to cause a piston 40 to quickly engage the actuator 38. When the ram 2 is moved downwardly by supplying fluid to the upper end 5 of the cylinder, the pistons 34 and 40 are biased downwardly by fluid flowing through a conduit 37. The hammer may alternatively be of the counter blow type.

Abstract: 1317510 Programmed computer STANDARD TELEPHONES & CABLES Ltd 23 Sept 1971 44391/71 Heading G4A A computer is conditioned to produce information for the assembly of electrical circuit units on a circuit board by storing in a memory of the computer information relating to the units, e.g., arrangement and function of terminals, storing data relating to physical characteristics of the units, storing a coded indication of a logic diagram of the circuit, comparing the indication with the information relating to the units to determine the number and type of units required, locating the units according to preselected criteria such as the number of connections between units, allocating weights to the locations according to similar criteria, interchanging or rearranging the units to improve the weights, determining the best result and producing a drawing of the required wiring. The board description (Fig. 3) stimulates a programme E1 which generates a model of the artwork used and stores it in the system's disc files. Details of the circuits and the connectors are checked by a programme E2 and stored in a Unit Type Catalogue. A coded description of the logic diagram is supplied, e.g., from punched cards, checked by programme M1 and fed to function packaging programme which notes important connection features i.e., those formed by non-crossing straight lines (Fig. 1, not shown) and minimizes the number of circuits receiving a signal. Programme M3 positions the circuits on the board and takes note of manually assigned data. The circuits are placed and awarded points for placing and simplicity of interconnections and sets of placings are built up. When all units are placed, adjacent units are interchanged to see if an improved score can be obtained. Programme M4 arranges the best connections for signals applied to a circuit containing a plurality of functional units, e.g., several AND gates or OR gates, and supplies data to a printer. Programme M5 ranks the possible patterns in order in a pattern hierarchy and feeds programme M6 which deals with less important wiring patterns, e.g., to reduce the number of plated through holes.
