Abstract: 607,487. Polishing cycle wheel rims. HERCULES CYCLE & MOTOR CO., Ltd., and CRANE, SIR E. F. Feb. 6, 1946, No. 3694. [Class 60] A machine for polishing a cycle wheel rim or the like comprises means for locating the rim in a substantially horizontal position, poweroperated means for gripping and rotating the rim about its axis, power-driven mops or the like movable in a substantially radial direction towards and away from the rim, and interlocking control mechanism for the rim gripping and mop moving mechanism. A cycle wheel rim 11 is located on a table 10 by three spaced rollers 12, 13 and is rotated by a driven roller 24, being pressed thereagainst by an idler roller 18 on a pivoted lever 19. Two mops 26, 27 are mounted on brackets 30 slidable on a horizontal guide 31 under the action of pneumatic cylinders 32, their outward movement being limited by adjustable stops 33. The rim is supported externally against the pressure of the mops by idler rollers 37 mounted on slides 38 operated by pneumatic cylinders 40. The controls for a pneumatic cylinder 23 operating the idler roller 18, the pneumatic cylinders 40 operating the idler rollers 37, and the pneumatic cylinders 32 operating the polishing mops are so interlocked that the mops cannot be moved into engagement with the rim until the rim has been gripped and is being driven, and the rim cannot be released until the mops have been disengaged therefrom. The mops and rollers are preferably enclosed by a hood having a counterweighted cover operated by a pneumatic cylinder 46 (not shown), so controlled that the cover is closed as the rim is gripped and before it is engaged by the mops, and does not open again until the rim has been polished and released. The hood is connected to a suction duct to remove dust. Sanding wheels may be used in the place of the mops. In addition to the mops 26, 27, further small, independently driven mops may be provided for simultaneously polishing the edges of the rim. The pneumatic cylinders may be replaced by hydraulic cylinders.

Abstract: 1,075,631. Vehicle brake arrangements. GIRLING Ltd. April 30, 1964 [Jan. 30, 1963], No. 3765/63. Addition to 967,408. Heading B7H. [Also in Division F2] In a vehicle with a front wheel suspended by a telescopic strut 12 incorporating an hydraulic damper and a suspension spring 20, a brake disc 22 is mounted on the wheel hub and braked by friction pads located in a caliper 25 which is pivotable about the damper, the axis of which is substantially at right angles to the axis of the disc. As shown, the caliper mounting on the strut is offset from and at a small angle to the central plane of the disc to provide a self-servo brake action in the forward direction of rotation of the wheel. The brake pads (23), (24) (Fig. 2, not shown) on opposite faces of the disc are applied respectively by a single hydraulic piston (27) in slave cylinder (28) and by the reaction on the caliper which pivots on the strut.

Title: Improvements in or relating to electric signal translating and recording devices
Inventor: TAYLOR MAURICE KENYON
IPC: G08C21/00
Filed: 1951-02-16
Abstract: 709,921. Recording-apparatus. FERRANTI, Ltd. Feb. 15, 1952 [Feb 16, 1951; March 9, 1951], Nos. 3785/51 and 5700/51. Class 106 (4). [Also in Group XXXVIII] A recorder consists of an opaque waxed paper sheet 48, Figs. 3, 19, mounted between a series of X, Y conductors 45, 46 defining a grid reference system. The X, Y co-ordinates signalled in the binary code (see Group XXXVIII) are decoded at 50, 51 respectively. The circuit from H.T. source 52 passes through the selected spark gaps in the X, Y decoders, over the selected X, Y recorder conductors and is completed by sparking through the waxed sheet 48 at the intersection of the selected X, Y conductors. The sheet 48 is viewed from the direction of the arrow o through a transparent chart 49 engraved with a version of the grid reference system. A lamp S illuminates the upper surface of the waxed sheet 48, the melting of the wax at the spark discharge point causing the appearance of a dark spot at that point. The conductors 45, 46 may be formed by fine wires strained across separate open rectangular frames, Fig. 17 (not shown), the waxed sheet 48 being detachably carried by an intermediate frame. The frame 35 carrying the sheet 48, may be mounted outside the X, Y conductor assembly, Fig. 19, but closely parallel to one of the conductor arrays. The reaction of the sheet 48 may alternatively be to the heat generated by the passage of current 'between the selected X, Y wires through an intervening bead 43 of high resistance. A polar co-ordinate or a hyperbolic reference system may be used and the reference surface may be spherical, e.g. in the case of a navigation system, or cylindrical, as in the case of an indicator diagram. Where a variable is to be recorded against time, the conductors of one of the arrays X, Y are marked sequentially by a timing device, e.g. a synchronous motor, Fig. 20 (not shown), or the sheet 48 could be driven at constant speed. The sheet 48 may be illuminated from below so that the selected, point appears as a light spot on a dark background. The sheet 48 may be tinted or treated so as to change colour on being heated. Material such as "Cellophane" (Registered Trade Mark) which, normally transparent, becomes translucent on heating, may also be used. Alternatively the material may be conductive and respond to electrolytic action. The sheet may be burnt or punctured by a spark discharge therethrough. A three dimensional display may be provided by arranging a number of recording surfaces as above described in a series of parallel planes, a material such as "Cellophane" being used in this case.

Abstract: 896,540. Optical joints. OPTISCHE INDUSTRIE DE OUDE DELFT N.V. Feb. 3, 1960 [Feb. 3, 1959], No. 3849/60. Class 97(1). An optical joint between a first pivotable tubular member and a second member includes a plane mirror carried by said second member and so linked to the pivotable member that it rotates by one half of the amount of the pivotable member which latter rides on an arcuate slide track on the said second member having a slot for the passage of light therethrough, a cover slide fixed to the mirror (and fitting closely to the slide track) helping to prevent outward passage of light through the marginal portions of the slot, and a hood attached to the pivotable member covering those regions of the slot not traversed by a light beam through the optical system and not covered by the cover slide. As shown in Figs. 3 and 4 a mirror 12 is attached to a cover slide 6 formed by two sector shaped plates 7, 8 and end plates 9, 10 terminating in ledges 19, 18 and defining an aperture 11, said cover slide being pivotably mounted in a part 3 of an optical apparatus for pivoting about an axis M through the plane of the mirror. In sector 8 there is a spiral slot 16 and in the adjacent and parallel housing wall of 3 there is a linear slot 17. An eyepiece 1 carries a hood 2 which can cover part of an opening 5 in the slide track 4 of the fixed part 3 of the apparatus, and which includes a portion parallel to sector 8 and having a spiral slot 15 of half the curvature of slot 16 in the sector 8. A pin 20 engages all three slots so that rotation of the eyepiece 1 causes a rotation in the cover slide 6 of half that of the eyepiece. A ray 14 will thus always be directed along the eyepiece axis. The cover slide and hood dimension are such that in an extreme position, as in Fig. 3, both co-operate to close the wide margin of the slot, the ledges 18 and 19 preventing the exit of tangential rays.

The individual fastener members are thus fabric-covered externally. Alternatively, the strip of non-metallic material may be secured marginally to a pair of stringer tapes spread apart so that the central part of each blank is without fabric backing. When bent to final U-form, the fastener members in this case are partly covered by fabric. The flat composite ladder-like strip, prior to the final bending, is as described and claimed in Specification 535,609.
