Title: Improvements in automatic clutch controls for motor vehicles and the like
Filed: 1929-06-11
Abstract: 313,452. Erdelen, O. June 11, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Controlling different functions by same lever; pneumatic controlling-apparatus.-The clutch is automatically disengaged when the accelerator is released by means of a piston and cylinder adapted to be connected, through a rotary valve operated by the accelerator, either with the atmosphere or with the engine induction pipe. The usual clutch pedal k controls the clutch through a rod c<1> which is also connected, through a pin-andslot d, to a piston a working in a cylinder b. A valve h, rotated by the accelerator pedal (not shown), puts the cylinder into communication either with the atmosphere through an adjustable passage ! l or with the engine induction pipe through a check valve s. The normal running position when the accelerator is depressed is with the cylinder connected to the atmosphere (as shown) so that the clutch is engaged by its spring. When the accelerator is released the valve is turned to its other position, a vacuum is formed in the cylinder b, and the clutch is disengaged. In order to allow the engine to be used as a brake the accelerator is arranged to rotate the valve h to release the clutch before it is moved far enough to open the throttle.

Filed: 1924-07-28
Abstract: 231,069. Marks, E. C. R., (Titusville Forge Co.). July 28, 1924. Bore-hole apparatus.-A casing slip for use with well-drilling apparatus comprises two or more units A, B co-operating with the tapered opening of a spider 11, and each comprising two or more sectors detachably hinged together so that the number of sectors may be readily increased or decreased according to the size of the casing to be held. The sectors are preferably U-shaped, one of the outer face having vertical threads 19 to prevent rotation in the spider; the inner faces 16 of the sectors have threads 17, alternately right and left handed, to prevent downward or rotational movement of the casing or one sector of each unit may have vertical threads 18 on its inner face. The side faces of the sectors have vertical semi-circular grooves to receive hinge pins 14, nuts 24 on the pins aving an annular projection 22 engaging a similar groove in the sectors to prevent lateral separation of the sectors; a shear ring 30 on each pin engages recesses in the sectors to resist relative vertical movement thereof. Screws 33 may be adjusted to limit relative pivotal movement of the sectors. A cable &c. 37 is attached by screws 39 to end members of a unit, and a central part of the cable may form a handle, or a separate handle 34 may be flexibly attached to each unit.

The films are preferably used as the outermost layers of the laminate to improve scratch resistance. Suitable lacquers are those containing an aliphatic polyisocyanate optionally admixed with an aromatic polyisocyanate and a compound containing hydroxyl groups, e.g. a branched polyester; lacquers containing a polyfunctional acrylate resin having free hydroxyl groups and a melamine-aldehyde resin or polyisocyanate may also be used. In a preferred embodiment, a light stabilizer is present in the lacquer. The lacquer may also be applied to the edges of the laminate to prevent the penetration of moisture into the polyvinyl butyral.

Title: Improvements in or relating to mechanical coupling means, more particularly for the coupling of two electrical connector members
Inventor: DUNCAN WILLIAM CHAMBERS WILSON
IPC: H01R13/623
Filed: 1965-04-30
Abstract: 1,138,364. Pipe coupling. PLESSEY CO. Ltd. 1 April, 1966 [30 April, 1965], No. 18274/65. Heading F2G. [Also in Division H2] In a coupling device in which plug-and-socket members are held together by a locking ring 3 rotatable on the plug 1, the ring has holes 17 which are resiliently engaged by spring balls 20 to resist relative rotation between the ring and the plug when the former is in either its locking or unlocking position. The locking action results from helical slots 15 in the ring which engage studs 14 of the socket member, and rotation of the ring acts to draw the members together or to force them apart. The ring is held freely rotatable on the plug 1 by a circlip 7 which engages a circular groove 8 in the ring.

Abstract: 1,217,063. Type-bar making machines. LINOTYPE G.m.b.H. 18 April, 1968 [24 May, 1967], No. 18277/68. Heading B6W. A device for left-hand indenting of lines cast on a type-casting machine comprises a locking nose, fitted in a pre-selectable position in the path of movement of the left-hand vice jaw or of a part connected thereto, and which engages in a groove of the vice jaw or connecting part. The Figure illustrates a line-casting machine in which the left-hand vice jaw 1 is connected to a rack 3 movable towards right-hand vice jaw 8 under the action of a piston-rod 4 of an hydraulic quadding device. An insert 21 carrying an adjusting piece 22 provided with a locking nose 23 can be mounted in a transversely movable slide 17 below the rack 3, the adjustment of nose 23 being longitudinally of the rack. When a groove 16 in rack 3 is opposite the nose 23, they are interlocked under the action of indenting solenoid 18; the jaw 1 is prevented from further quadding movement by interlocking of insert 21 with screw 6 of a locking device which can be finely adjusted to obtain the desired former. In operation, the suitably adjusted insert 21 is secured to slide 17 and indenting solenoid 18 is actuated; the quadding device moves the vice jaw 1 until the nose 23 interlocks with groove 16, and locking screw 6 is operated; the matrix line is justified by a device (not shown) connected to brace rod 9; after any minor adjustment of screw 6, the line is cast; the solenoid 18 is de-energized, screw 6 is unlocked and return spring 19 takes the nose 23 out of groove 16. If unjustified lines are required, the vice-jaws are centred, and movement of brace rod 9 is prevented by trunnion 11.
