Abstract: 1433719 Electromagnetic friction clutches; electromagnetic full-face disc brakes WARNER ELECTRIC BRAKE & CLUTCH CO 23 Sept 1974 [5 Oct 1973] 41378/74 Headings F2C, F2E An electromagnet friction coupling, a clutch or brake, having a stationary magnet 27<SP>1</SP> fixed in a casing 191 has a rotor 35<SP>1</SP> fixed to a rotatable shaft 16<SP>1</SP>, the axial position of rotor 35<SP>1</SP> being defined by a flange 61 on the fixed part of the coupling, or on the rotor 35<SP>1</SP>, engaging in a groove 63 on the other member. As shown flange 61 is fixed to the core 26<SP>1</SP> of the magnet 27<SP>1</SP> and engages a groove 63 on the rotor defined by a shim between the flange 61 and a flange of the rotor and a further shim between flange 61 and a yet further shim axially located by a spring ring 70. The rotor has a friction lining 37<SP>1</SP> towards which an armature or the driven shaft of a clutch, or on a fixed brake member, is attracted on energization of coil 27<SP>1</SP>. The part of the coupling shown is fixed to an electric motor 10<SP>1</SP>, shaft 16<SP>1</SP> being the motor output shaft. The flange and groove connection 60 ensures that the correct axial gap between faces 54<SP>1</SP>, 55<SP>1</SP> is established even with the rotor 35<SP>1</SP> disconnected from the shaft 16<SP>1</SP> and the coupling portion removed from motor 10<SP>1</SP>, so that no skill is necessary in the assembly of coupling portion, motor and shaft. Since flange 61 and groove 63 perform no function once the coupling is assembled the shims against the flange can be of easily wearable material, to ensure that flange and groove do not restrict rotation of the rotor.

Title: Improvements to Cross-Bar Crosspoint Matrices
Inventor: LUCAS PIERRE
IPC: H02B1/20
Filed: 1968-08-30
Abstract: 1,176,278. Electric selectors. P. LUCAS, and A. SAUTEL. 30 Aug., 1968 [31 Aug., 1967], No. 41460/68. Heading H1L. In a mechanically latched cross-bar switch having no contact pile ups or multiples, each select bar 101, 102, 103 is conductive and carries a plurality of conductive resilient fingers 111, 121 ... 123, and, each " hold " bar 202 is also conductive and is provided with apertures 21, 22, 23 which normally coincide with a select bar. In operation, a hold bar is moved to the right (as seen in Fig. 1) so that the apertures, e.g. 21 overly a normally adjacent select bar, i.e. 102. Then a select bar, e.g. 102 is moved (outwardly from the plane of the paper) so that its fingers move through the apertures. Thereafter the hold bar and then the select bar are restored whereby the selected finger, i.e. 122 is trapped in the angle between the hold bar and a flap 222 which extends transversely of the bar. (The flap may be formed by bending over the portion of the hold bar that is stamped out  during manufacture of the aperture). In order to release the " one-wire " connection from a hold bar 202, via a finger 122 to a select bar 102, the hold bar is again moved to the right so that the finger snaps through the aperture on the left of the flap against which it was trapped. If a multi-wire connection is required, adjacent select and hold bars may be ganged. The wiping action of the fingers ensures that clean contacts are made. Vibration of the fingers is minimized by means of a coil spring having turns of different diameters (Fig. 3, not shown), by using a clamping bar attached to the select bar (Fig. 4, not shown), by using a plastics sleeve on the finger (Fig. 5, not shown) or by having two contiguous fingers which clamp each other by mutual impact when they are vibrated (Fig. 6, not shown).

Abstract: 1, 013, 923. Apparatus for charging electrophotographic surfaces. RANK-XEROX Ltd. Nov. 28, 1961 [Dec. 9, 1960], No. 42560/61. Heading G2H. A xerographic member is charged by passing across its surface in contact therewith a plurality of electronically conductive electrodes. In Figs. 1 and 2 a xerographic plate 11 held by clips 17 on a movable base plate 12 is charged through a number of spaced fine wires 20 clamped between bars 21 which are connected to a potential source 42 but electrically connected to the bars only by a layer of resistive material 22, so that if one wire is temporarily grounded little effect would be produced on the adjacent wires. The wires may be of stainless steel, phosphor bronze, foil, metallized plastic sheet suitably slit and the wires may be woven into a fabric of insulating strands which maintain the spacing between the wires (Fig. 6 not shown). It is explained that the charge pattern formed on the plate is in the form of a series of strips which may correspond to half tone rendering, but, by arranging the wires slantwise or in layers a more uniform charge may be applied to the plate (Fig. 11, 12 and 13 not shown). The clamping arrangement may be pivoted within a holder and means may be provided for moving the charging wires away from the plate and into the holder (Fig. 9 not shown). Alternatively, where the plate to be charged is on a drum, the wires may be stretched between two supports so that they touch the surface tangentially (Fig. 7 not shown) or they may be formed by winding a wire helically around a channel shaped holder and cutting the wires along the rear side of the holder (Fig. 8 not shown). In Fig. 10 the wires are secured on a drum coated with high resistance material and located within a shield, the drum being rotatable so that the wires may be cleaned by a pad 48 inside the shield. Specification 1,013,924 is referred to.
