Abstract: 868,083. Two-part couplings. INTERNATIONAL COMPUTERS & TABULATORS Ltd. May 28, 1959 [May 9, 1958], No. 18568/58. Class 38 (1). An electrical connector comprises a socket and a relatively rotatable plug provided with rows of co-operating contacts, means for ensuring that the plug enters the socket with the contacts out of alignment and means for locating the plug in the socket. As shown, a socket comprising end plates 1, 2 connected by bars 3, 4 has, extending lengthwise thereof, four rows of contacts 5 carried on conductive members 6, held by clamping members 7, 8 and supported by adjustable buffers 53. A plug 10, Fig. 7, with four rows of contacts 17 is shaped for entry into the socket with its contacts out of alignment with contacts 5, the socket entrance being defined by plug controlling means comprising two pairs of pivoted arms 18, 19 and 20, 21 urged together by springs 26, 27 and held by latches 32, 33 on rockable spindles 36, 37. The plug, during entry, is guided by a rod 13 which slides in a bore.57 therein until pins 14 on the plug engage apertures 15 in a rotatable locating plate 12.. Pins 42, 43, Fig. 4, on the plate 12 extend through slots 44, 45 in the plate 2 and through slots 40, 41 in levers 38, 39 which rock spindles 36, 37. Thus, movement of the plug 10 about its axis rocks spindles 36, 37 and releases latches 32, 33 thereby allowing the plug 10 to open the controlling means and to turn until contacts 5 engage contacts 17. Locking levers 50, 51, also rocked by spindles 36, 37, engage a groove 52 in the plug 10. In another embodiment the plug has two diametrically opposed ears which are passed through slots in a plate to ensure correct insertion of plug pins 14 into the apertures 15 in the locating plate 12, the alignment of plug groove 52 with the slotted plate permitting rotation of the plug and plate 12 and the latter being held in the rotated position by a notched spring-urged arm engaging pin 43.

Title: Improvements relating to friction pivots for casement and other pivoted windows
IPC: E05D7/08
Filed: 1932-07-05
Abstract: 397,284. Pivots for windows. GIBBONS, Ltd., J. and GIBBONS, P. E., St. John's Works, Church Lane, Wolverhampton. July 5, 1932, No. 18993. [Class 65 (ii).] In a pivot for windows having metal frames, in which the sash and fixed frame are formed of metal bars with exposed flanges overlapping one another, the pivot is secured to the frame only by easily accessible removable means and the frame is provided with a transverse groove through which an external flange on the sash can pass longitudinally, so that the sash can be readily removed from the frame. In the construction shown, a sash bar a, with flanges a<1>, a<2>, has fixed to it by screws b<1> a trunnion b which bears in a split socket c secured to the flanged frame bar g by screws f. The split socket has lugs c<1>, c<2> through which passes a screw d provided with a hand-nut e by which the friction of the pivot may be adjusted to bold the window at any angle : the lug c<1> fills a cut-away part of one flange g<1> of the frame bar g, so that the lugs do not hinder removal of the pivot. The screws f are easily accessible, but the flange a<1> of the sash bar overlaps the edge of the frame bar g ; to allow complete withdrawal of the sash and pivot, a transverse groove h is made in the frame bar g, through which the flange a<1> of the sash bar can pass longitudinally when the window is opened as shown. The groove h is preferably slightly inclined, so that its inner end is behind a downward flange of the split socket c, and the sash has to be opened more than a right-angle for withdrawal. The outer end of the groove h may be filled by a tongue j on the socket c, or by a fibre or other temporary filling. The frame bar g, being weakened by the groove h, is reinforced by a metal strip screwed on underneath it. Specifications 5007/12, [Class 65 (ii), Hinges &c.], and 388,533 are referred to.

[Also in Group XXXI] A road wheel suspension (see Group XXXI) for light vehicles is adjustable to suit altered loading and comprises a strut, having two springs 20 and 21 disposed within telescopic protective sheaths 7 and 30, a member 19 coupling the two springs together and an adjustable abutment operative, in one position to leave the member 19 free to move and both springs active in series, and in another position to hold the member 19 immovable thus putting one of the springs out of action. The main spring 20, Fig. 2, is supported at one end by a carrier 6 connected to the top bearing head 37, and at the other end by a cylinder 19 which is connected to the bottom bearing head 36 directly, or through an auxiliary spring 21, depending on the position of the rotatably adjustable sleeve 28. The abutment ring 25, Fig. 4, has a square aperture corresponding to the shape of the sleeve 28 so that when the sleeve 28 is in a position where the cross section of the sleeve 28 is in register with the aperture in the abutment ring 25 the cylinder 19 can move downwardly and the springs 20 and 21 are coupled in series; when the cross section of the sleeve 28 is not in register the cylinder 19 is held between the top edge of sleeve 28 and bottom edge of the resilient bush 27 lying beneath the collar 26 which supports the base of spring 21, in which position of the sleeve 28 only spring 20 can be displaced by loading the strut. To facilitate adjustment the auxiliary spring may be compressed to take the unloaded weight of the vehicle and hold the cylinder 19 against the bush 27. A rod 10 connected to the bearing head 37 is guided in a tube 15 connected to the bearing head 36 and a buffer spring 12 on the end of rod 10 comes between them for large extensions. A ball catch 34 holds the adjustable sleeve 28 in either of its two positions determined by a grub screw 32 working in an annular slot in the sleeve 28. Figs. 5 and 6 show an alternative construction in which the springs are connected by a sliding ring 19<SP>1</SP> with inwardly directed projections 25<SP>1</SP>. A tube 15<SP>1</SP> connected to the bottom bearing head has fixed at its upper end a ring 27<SP>1</SP> with diametrically opposed recesses 23<SP>1</SP> to receive the projections 251. Abutting the bottom edge of the ring 27<SP>1</SP> is a rotatably adjustable sleeve 28<SP>1</SP> having deep recesses 28<SP>11</SP> which in one position, determined by a projection 32<SP>1</SP> working in a recess 33<SP>1</SP> in ring 27<SP>1</SP>, are opposite the projections 251 and permit movement of the sliding ring 19<SP>1</SP> downwards against the auxiliary spring. In this embodiment the central guiding rod carrying the buffer spring 12<SP>1</SP> also has a piston head to give the strut hydraulic damping.
