Abstract: 1,241,054. Xerographic Imaging. RANK XEROX Ltd. Aug.27, 1968 [Aug. 28, 1967], No.40814/68. Heading G2H. A xerographic imaging methode comprises the steps of providing a radiation pattern and exposing a phosphorescent support to the pattern positioning a portion of a uniformly charged photo-conductive surface sufficiently near the support to dissipute the charge on the surface in image configuration and developing the latent image so formed with electro-scopic marking material. In one embodiment a cathode ray tube 28 generates charcters at its face 30 adjacent a phosphorescent support in the form of a roller 24 which imagewise discharges the uniformly charged photo-conductive surface of a drum 20. The support 24 and drum are driven sychronously. A viewing screen 38 permits viewing of the image formed on the support 24. The phosphorescent roller 24 may be replaced by a belt (48) Fig. 2 (not shown) impregnated with phosphors and the drum 20 by a belt (26). In another embodiment, an opaque document (62) Fig. 3 (not shown) is carried by a moving platen (64) past an aperture (69) to expose the phosphorescent roller (24).

Patent GB-1117502-A (GB)
Title: Improvements relating to bulky textile yarns
Inventor: SAYERS LESLIE WALTER
IPC: D02G1/18
Filed: 1964-10-07
Abstract: Bulk is imparted to continuous filament yarn by differential shrinkage between two or more constituent interlaced bundles of at least two different types of filaments, and the effect may be enhanced by subsequent falsetwist crimping, texturising within a turbulent fluid zone as described in Specification 732929, and/or forming crunodal loops in preselected filaments.  Each bundle has a twist of 0-1 turns per inch which is not increased by interlacing (effected, under controlled tension and without formation of loops) by air jets.  The shrinkable (10-20%) component (15-75% by weight) may be stretched, but unstabilised, filaments of nylon 6 or 66, copolymers of acrylonitrile and vinylidene chloride, acrylics, polyesters and polyolefins: an unshrinkable component may be stabilised forms of such filaments or cellulose acetate or triacetate, viscose rayon including polynosics.  In a continuous process, one or both forms of filament may be freshly spun or drawn from supply spools, stretched (if necessary) between godets, combined (in passing over one godet) passed through an air jet interlacer, and collected on bobbin(s) by a ring and traveller.  The differential bulk effect is developed by subjecting the running yarn or wound hanks to heat and/or moisture e.g. in a liquid bath or steam chamber: alternatively, bulk may be developed after weaving or knitting the yarn into fabric the final form of which may exhibit crepe weave or marl appearance.  The bundles may be similar or different as regards the nature of the materials, denier, the number and the cross-sectional form of constituent filaments, the direction of residual twists, lustre or dye receptivity, and the degree of interlacing may vary along their length: resultant esthetic effects may occur in the yarn and/or fabric.  Interlaced yarns, perhaps of different construction and finish may be used as warp and/or weft in fabrics.

Title: Improvements in a screwthreaded split-bolt releasable fastener
IPC: F16B21/16
Filed: 1963-10-17
Abstract: 1,059,134. Bolts. AERPAT A.G. Oct. 17, 1963 [Oct. 22, 1962], No. 41005/63. Heading F2H. [Also in Division E2] A bolt for quick securement to (and release from) a nut has a shank 12 formed from at least two parts 30, 31 which can close together at their threaded ends 32 to be smaller than the nut bore, when a button 46 is pushed into the hollow bolt head 14. A compression spring 52 normally urges the button 46, a notched washer 40 (pushed against a shoulder 42 in the button) and a plunger 36 secured to the washer 40 by edge notches 38, all to the left as shown in Fig. 1. This ensures also that a ball 62, rotatably held in the end of the plunger 36, is drawn, as shown, into a narrow portion of a cam cavity formed between the shank parts 30, 31 so that these are forced apart at the threaded ends 32 to engage the nut, the parts pivoting where they project inwardly to contact the plunger 36 in the region of a cover 22 which closes the head 41. The cover 22 is secured against turning in the head 14 and has a non-circular hole 28, Fig. 4 (not shown), through which the shank parts 30, 31 and the plunger 36 pass so that they cannot rotate with respect to the head. Outwardlybent ends 34 of the parts 30, 31 retain the parts in the head and are angled so that the spring 52, possibly aided by a split ring 60 in grooves 61, urges the threaded ends 32 together. Depression of the button 46 compresses the spring 52 against a washer 54 and moves the plunger 36 and ball 62 to the right, Fig. 2 (not shown), so that the latter enters a wider portion 67 of the cam cavity to allow the shank parts 30, 31 to pinch on the plunger adjacent the cam cavity. In this position, the bolt (with the end 23 of the cover 22 abutting a workpiece) can be inserted in a nut, until the button 46 is released for the threads to engage. The bolt is then given a few turns to tighten the nut for securement. A quick release is obtained by depression of the button.

IPC: H01H33/83
Filed: 1958-12-24
Abstract: 871,701. Gas-blast switches. COQ N.V. Dec. 24, 1958 [Dec. 28, 1957], No. 41721/58. Class 38 (5). A gas-blast circuitbreaker has two pairs of contacts connected in series and arranged in separate arcing compartments, one pair being used to interrupt currents up to fullload value and the other pair to interrupt overload and shortcircuit currents. The breaker comprises an insulating tube 1 enclosing coaxial insulating tubes 4, 6, 13, 14, and fixed metal contact rings 5, 7, which connect with supply leads 16, 18, through rings 15, 17. The tube 13 has a cylinder 11 in which moves a spring-controlled piston 10 carrying a valve-type contact 9 which co-operates with contact 7 and controls the opening 8, a bushing contact 19 which cooperates with a tubular switching-rod 20, and a contact stem 23 which passes through an insulating-ring 26 to engage a spring-controlled stem 25 movable in the rod 20. The latter is connected by an insulator 21 to a hollow switching- bar 22. In normal operation the rod 20 is withdrawn from the contact 19 and an arc is formed between stems 23, 25, when the latter engages a collar 37, this arc being extinguished by compressed gas supplied from a pipe 30, through the space 31 and ring 26 to the arcing compartment 33, and exhausted through the space 32 and pipes 34, 35. On overload or short-circuit, compressed gas is supplied through the pipe 38 and space 28 to the arcing compartment 29, and lifts the piston 10, extinguishes the arc between contacts 7, 9, and exhausts through the opening 8. Gas is also supplied from pipe 30 as before and the contacts 19, 23, 20, 25 open after the arc has been extinguished, to isolate the breaker before the gas supply is cut off and contacts 7, 9 reclose.

Abstract: 1,076,739. Change combination locks. SARGENT & GREENLEAF Inc. Oct. 2, 1965, No. 41888/65. Heading E2A.  A tumbler wheel for combination locks comprises a hub member 11  with external teeth enclosed by two interengaging annular members, a case 26 and a cover 27 which have corresponding recesses defining a force receiving gate when they are secured to the hub member by rotating one annular member relatively to the other whereby sliding shoes 37, engaged in spaced walls 32 on the case slide into engagement with the serrated periphery 15 of the hub member and are disengaged therefrom to free the rim members for relative rotation so that the recesses are not in alignment to allow changing the combination by rotating the dial of the lock. To disengage the annular member from the hub a cam 53 supported in apertures 49, 33 in the annular members and anchored to the case 26 by a knob 56 is rotated anti clock- -wise by the combination change key. The cam strikes a shoulder 60 on the cover 27 which rotates so that shaped zones 52 thereon disengage an inclined surface on the shoes 37 and disengages them from the hub rim. After changing the combination the cam is then rotated clockwise striking another shoulder 59 on the cover which rotates moving the shoes to engage with the teeth on the hub member, and peripheral recesses 34, 48 on the case and cover are aligned to receive a fence. In a modification the shoes are replaced by two arcuate members slidably supported by the case and serrated on one side to engage the hub serrations and with projections on the other side which cooperate with spaced recesses in the cover. Alternatively the case may have a series of resilient members with serrated surfaces. A fly 19 supported by the hub member has a recess 22 for accommodating a drive pin 17 which drives the next tumbler wheel. The rim portion is formed of low density plastics material to prevent X ray and other photographs being taken.
