Title: Electrophotographic material
IPC: C08F2/48
Filed: 1961-07-21
Abstract: 990,368. Photo-conductive materials. KALLE A.G. July 21, 1961 [July 28, 1960], No. 26611/61. Addition to 942,810. Heading H1K. The sensitivity to light of a colourless or pale non-resinous compound which is solid at room temperature and which can act as an electron acceptor in a molecular complex is increased by the addition to the compound of a relatively small quantity of an organic photo-conductive compound containing one or more aromatic or heterocylic rings and acting as an electron donor. A small quantity of a sensitizing dyestuff may be added to this photoconductive material which may be mixed with a natural or synthetic resin binder before being applied to a conductive support. The photo-conductive material is particularly intended for electrophotographic purposes but may also be used in photocells, photo-resistances, camera tubes, and electro-luminescent apparatus. Many examples given of electron acceptors are specific examples of aromatic and polynuclear hydrocarbons extensively substituted by strongly electron attracting groups such as chloro, bromo, cyano, and nitro groups; of cyclic anhydrides of aromatic acids, especially when substituted by strongly electron attracting groups; of similarly substituted quinones; and of aromatic diketones. It is stated that practically any photo-conductive organic aromatic or heterocyclic substance is suitable as the electron donor provided that it is not hygroscopic, does not possess high electrical conductivity, and that it does not contain strongly polarizing substituents imparting electron accepting properties. Preferred substances are multi-nuclear aromatics or heterocyclics which are either unsubstituted or which contain electron repelling substituents. Many specific examples are given which fall within the following classes:-polynuclear hydrocarbons, and hydrocarbons of the diphenyl, terphenyl &c. series, especially when substituted by groups such as amino, methoxy, ethoxy, and alkyl amino groups; heterocyclics such as: diphenylene oxide; carbazoles; N- elkyl carbazoles; indole; oxadiazoles and triazoles, and their N-alkyl and N-acyl derivatives (especially with C-p-aminophenyl substitution); hydro-imidazoles; thiazole derivatives; oxazoles, imidazoles, furans, thiophenes and pyrroles, particularly those with aromatic substituents; polyvinyl aromatic compounds, e.g. poly-2-vinylnaphthalene; and polyvinyl heterocyclines, e.g. poly-N-vinyl carbazole. Examples are given of the fabrication of electro-photographic plates using the photo-conductive material of the invention. Reference has been directed by the Comptroller to Specifications 851,218, 856,770, 874,437, 874,634, 883,787, 883,788 and 883,790.

As shown, a driving shaft 3 in an embroidery machine pivotally carries a plurality of pairs of members 5 rotatably supporting shuttles S the bodies S' of which have peripheral gear teeth 4 meshing with a gear 2 rigid with shaft 3. A circumferential groove S in body S' is engaged by a pair of pins 7 journalled on member 5, and a circumferential rib 9 on gear 2. Members 5 may be pivoted outwards from their operative positions to provide access to the bobbin carriers S" mounted therein. The shuttles co-operate with respective horizontal needles N mounted on a reciprocating bar 21. The work M passes between a vertical surface and a spring-biassed presser plate 20. Needle thread passes from a tensioner 31 to guides 32 and 33 positioned one on each side of a rotary shaft 24 the thread returning -from guide 33 to guide 32 on its way to the needle. The doubled thread between said guides is acted upon by a rotary take-up member 25 generally L-shaped in cross section and rigid with shaft 24. Work M is fed longitudinally, while shaft 3, needle bar 21 and shaft 24 are shifted laterally as a unit in accordance with the pattern requirements. In a modification, each shuttle of a pair is driven from a separate shaft pivotally supporting the associated member 5.

Title: Improvements relating to apparatus for hauling wagons
IPC: B61J3/08
Filed: 1949-10-19
Abstract: 688,468. Hauling railway wagons. NORTONS (TIVIDALE), Ltd., HOWARD, A. M., and HARPER, W. G. Oct. 11, 1950. [Oct. 19, 1949] No. 26896/49. Class 104 (ii). In a railway wagon haulage apparatus in which a bogie runs on a narrow track between the wagon rails and carries a hook to engage a wagon axle the hook is of an upright U-shape pivoted about an axis transverse to the bogie and is raised from a position in which it passes beneath the wagon axle to a position in which one of its jaws will pass the axle whilst the other jaw will engage the axle to tilt the hook to a position in which the jaws will embrace the axle and the hook will be retained in such position by a catch. A bogie 1 mounted on a narrow track 8 arranged between standard gauge rails is drawn in one direction by a main hauling rope 22 attached to a spring buffer 24, and in the other direction by a trailing rope 26 connected to a cross-head 14 slidably mounted between channel members 12, 13 of the bogie and movable between stops 18, 20. When the bogie 1 has been moved to a position beneath a wagon additional tension is applied to rope 26 to slide the cross-head 14 towards the stop 20 and, through links 38, to move arms 34, 35 and rollers 42 carried by a hook member 28 mounted thereon upwards into a position in which the rollers 42 will engage the wagon axle 30. The bogie 1 is then moved along by the rope 26 until the pressure between the rollers 42 and the axle 30 overcomes a spring 45 to rock the hook member 28 to rest above a pivoted catch 50 and move rollers 44 into a position in which they will engage the other side of the axle 30. Provided tension is maintained in rope 26 the wagon may now be moved in either direction by the bogie 1. When the tension in rope 26 is released the cross-head 14 moves towards the stop 18, the arms 34, 35 and rollers 42, 44 are lowered and the catch 50 is tilted upwards to release the hook member 28 by the descending arms 34 carrying the catch 50 into engagement with a stop 56 whereupon the hook member 28 is rotated by the spring 45 into contact with a stop 46. Specification 688,467 is referred to.

Title: Process for the production of foamed polyurethane products of high molecular weight
IPC: C08G18/42
Filed: 1954-09-16
Abstract: Foamed polyurethane products of high molecular weight are prepared by reacting an unsaturated branched or linear polyester in which substantially all the terminal groups are carboxyl groups, and a polymerizable vinyl or allyl compound, e.g. styrene or a diallyl ester of a dicarboxylic acid, with a polyisocyanate in the presence of a polymerization accelerator.  The unsaturated polyesters may be prepared by esterifying a saturated dicarboxylic acid with a large excess of a polyalcohol, an unsaturated carboxylic acid anhydride such as maleic acid anhydride being added to the product.  A small proportion of a saturated and/or unsaturated polyester containing hydroxyl groups may be added with the anhydride.  The foaming process may be carried out by adding the vinyl compound and the polyisocyanate together with a little polymerization accelerator and an activator to the carboxyl polyester and bringing the mixture to a temperature between 0-100 DEG  C.  Specified accelerators are benzoyl peroxide and azodiisobutyric acid nitrile, specified activators are tertiary amines, phosphine or heavy metal salts, while toluylene diisocyanate is the specified isocyanate.
