Abstract: 1299260 Bogies SOC ANON USINES EMILE HENRICOT 18 June 1970 [23 March 1970] 29560/70 Heading B7L A wheeled bogie comprises two parallel sideframes 1 each having two bores 2 which are each divided by a rim 3 into two annular shoulders 4, 5 for receiving torus-shaped resilient hoops 14, 15. Each bore and its respective hoops receive therethrough an axle box 6 having a first cylindrical part which projects through the bore 2 and hoops 4, 5 and which has a radial flange 7 which co-operates with the shoulder 4 to retain the hoop 14. The axle box 6 has a further part 10 which is secured to the cylindrical part so that a flange 11 on the part 10 retains the hoop 15. The wide-frames 1 are thus suspended resiliently on the axle boxes 6. The hoops 4, 5 may have varying cross-sections, Fig. 7, so that, if there is a misalignment s of the axle boxes on opposite side-frames, this may be corrected by rotation of the appropriate hoop through an angle α where sinα = #/e, e being the displacement between the centres of the outer and inner peripheries of the hoop.

Abstract: 703,983. Stamping or shaping cartons &c. FRANGHIA, S. B. Nov. 18, 1949 [Nov. 20, 1948], No. 29587/49. Class 100 (2). [Also in Group XVII] A machine for pressing a cup-shaped container from a blank, the container having crimped sides and peripheral flutings or beadings around the upper edge, comprises a plunger 8 movable towards a fixed support 19 through a co-axial reciprocating annulus 28, the annulus and fixed support carrying opposed rows of intercalating pivoted pawls 25, 41 for crimping the container sides. Sheet material 49 is fed across the support 19 by rollers 58, 51, 62, 63 and passes between the upper and lower rows of pawls which are horizontal and separated when the plunger is in its uppermost position. As the plunger descends, the annulus 28 is moved downwards by a cam 37 through linkage 30-35 to clamp the sheet 49 under a spring-loaded ring 43 and cut the blank with a cutter 39. The blank is clamped and crimped betwen the pawls which tilt to press it against the sides of the plunger. The plunger forces the partly formed container into a die comprising separable sectors 23 brought together against return springs 27 by rods 42, carried by the annulus 28, acting on cam surfaces integral with the sectors. The head 13 of the plunger is movable into the body against a spring 14 and in the final stage of pressing. a cone 48 forces outwardly elements 47 which press the upper end of the container into peripheral serrations in the die. On the return stroke of the plunger, the annulus 28 rises, releasing the material 49 and permitting the sectors of the die to separate to release the completed container. Specification 611,325, [Group XVII], is referred to.

Title: Improvements in or relating to radiation-sensitive diazotype materials
Inventor: KENDALL JOHN DAVID
IPC: G03C1/60
Filed: 1956-09-28
Abstract: 815,005. Photographic diazotype materials. ILFORD Ltd. Nov. 18, 1957 [Sept. 28, 1956; July 3, 1957], Nos. 29673/56 and 21027/57. Class 98(2) A two-component material comprises in order a layer containing a diazo compound, a fusible layer, and a layer containing a coupler, the whole carried on a sheet or film support which latter may be on either side. The material may be made by coating the layers on the support but preferably the layer applied on to the fusible layer, either that containing the diazo compound or the coupler according to the order of coating, is applied by spraying to prevent any tendency to effect fusion and hence premature coupling. In an example a methanol solution of 4-ptolythio - 2 : 5 - diethoxy benzene diazouium zincichloride is coated on to tracing paper by a roller and scraper technique and dried, the second layer is paraffin wax of melting point 60‹C. applied by dip coating from a molten bath thereof, when cold the coupler layer of dimedone and stearylamine in chloroform, is sprayed on, and finally the material is sprayed with an ethyl acetate solution of cellulose acetate to provide a protective coating. A second example specifies similarly 4 - benzoylamino - 2 : 5 - diethoxy benzene diazonium chloride as sensitizer and resorcinol as coupler. Exposure of these materiels to light through a suitable master and heating to about 80-100‹C. produces respectively orange and brown images on clear white backgrounds. Exposure by a mercury vapour lamp may provide sufficient heat in the case where the master carries an image in radiation absorbing material, such as printer's ink, carbon or silver, to ensure dye production in image areas while destroying the diazo compound in non-image areas and thus leave the product stable to subsequently applied heat or light. Exposure by heat or infra-red only may be without effect on the diazo compound of the non-image areas and these may subsequently be destroyed by daylight or ultra-violet radiation, or may be separately coupled to form a background in azo dye of different colour to that of the image areas, or may be used to apply a second image by light exposure and coupling, or a second image by a second heat or infra-red exposure. Diazotized 1 - amino - 2 : 6 - dimethoxy benzene is quoted as a diazo compound of high-heat stability for these purposes. Other substances for the fusible layer are indicated. Specification 759,045 is referred to.

S l i d i n g clasp fastenings, - Cordedged bands for sliding clasp fastenings, wherein the fastening members c are clamped to the cords a are caused to assume curved forms by weaving the band b and cord a together and stretching the cord during the weaving by winding the corded band on to a conical take-up roller, so that the degree of stretching gradually decreases towards the non-corded edge. The subseqently contracting cord causes the band to be curved as shown. The cord and band may be stretched after weaving so as to maintain a converse curvature in spite of the subsequent contraction. The Specification as open to inspection under Sect. 91 (3) (a) refers to a stretching in conjunction with an ironing process, and to the stretching of a cord and of the tubular cord in which it is enclosed.
