Title: Improvements in or relating to shoe upper shaping machines
IPC: A43D21/12
Filed: 1936-08-25
Abstract: 482,275. Shoe - lasting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and ROBERTS, W. T. B. Aug. 25, 1936, Nos. 23283 /36 and 8952 /37. [Class 17 (i)] The machine described in Specification 470,749 is improved. The retarding fingers 3 which, as described in the prior Specification, co-operate with the wipers during the over-wipe, are caused to co-operate with the wipers during the up-wipe also. These fingers are formed so that their forward edges, when the fingers are open, have the contour of the toe end of the shoe, and they are moved over and off the toe end of the insole to clamp the edge of the upper against the wipers during the up-wiping movement. The wipers may be backed off slightly so that they do not scuff a light upper. To prevent the toe end of the insole being lifted from the last as this is depressed to bring the insole below the wipers for the over-wiping movement, the wipers are backed off as the shoe is depressed. Also, as the wipers advance to commence the over-wipe, they are lifted slightly, to ensure that they do not disturb the end of the insole. For the first part of the advance of the wipers, the fingers 3 are advanced also. At the end of the advance of the wipers, the automatic stop of the machine occurs, during which stop, as described in the prior Specification, the operator may inspect the upper to see if the lasting has .been properly performed. When the machine is re-started, the wipers are lifted slightly and then retracted nearly to the edge of the last. They are then depressed and advanced to a position somewhat short of the original full advance, and the tacks are driven. These modified movements are produced by modifications in the cams described in the prior Specification. The fingers 3 are modified to allow tilt longitudinally of them. Each finger pivot 19 carries a member 33 formed with a recess to receive a cylindrical rib extending across the finger. The rear end of the finger is replaced by a head 39 carried by a spring plunger 41 housed in the pivot.

Title: Improvements in light projectors
IPC: F21S13/00
Filed: 1948-09-07
Abstract: 650,352. Light projectors. HOLOPHANE, Ltd., and ENGLISH, S. Sept. 7, 1948, No. 23524. [Classes 75(ii) and 75(iv)] A light projector for floodlighting or street lighting comprises a composite reflector having a central part 14 of elliptical section with its near focus F at the light source and an outer part 15 of parabolic section with its focus also at the light source and a lens 18 equal in width to the elliptical part of the reflector and centred at the remote focus P of the elliptical part of the reflector. The projector may be trough-shaped to accommodate an elongated fluorescent tube or it may be circular for use with an incandescent lamp in which case an aperture is provided at the top for a lamp holder. The converging lens 18 is integral with or attached to a preferably flat glass or transparent plastic plate 17 closing the mouth of the reflector and is formed with a series of prisms which are either straight and parallel to the the light source when the projector is trough-shaped or circular when the projector is circular. In either case the apical angles of the prisms increase from the outermost prism 18a to' the central prism. Rays striking the lens directly are refracted to form a beam 62-70 which may be made parallel by arranging the focus of the lens to lie at the light source; rays reflected by the central elliptical part 14 of the reflector pass through the centre of the lens where the prisms either cause only slight deviation or are omitted and the rays are transmitted in diverging directions 84-90; rays reflected by the outer parabolic part 15 of the reflector pass undeviated through the outer part 21 of the closure plate 17 to form a parallel beam 76-82 of annular section or two distinct parallel beams according to whether the fitting is circular or troughshaped; and rays which strike directly the outer part 21 of the closure plate pass therethrough with slight displacement and form a divergent beam 72, 74. Diffusion of the various beams may be effected by forming the prisms of the lens 18 with curved surfaces or by providing flutes on the inside of the lens 18 and by forming convex or concave flutes on the outer part 21 of the closure plate or by stippling the outer part 21 or the whole of the closure plate. The closure plate may carry parallel prisms to deviate laterally the emitted light. The reflector may be made of prismatic glassware as described in Specification 315,114, [Class 75(ii)], or it may be specular and made of metal. A street lighting fitting may be formed by mounting two of the above described projectors and a third lighting unit of a different kind giving a wide beam, within a single lantern framework, the two projectors directing beams along the street in opposite directions and the third unit illuminating the street area below the lantern. The axis of the projectors may be tilted to divert the beams below the horizontal or the cover plates of the lantern may be provided with horizontal prisms deviating the beams downwardly.

Title: Apparatus for cleaning and disinfecting articles
IPC: A61L2/00
Filed: 1966-05-26
Abstract: 1,142,075. Disinfecting chamber. VIBRASUG, A.B. 26 May, 1966 [28 May, 1965], No. 23563/66. Heading ASG. Apparatus for cleaning and disinfecting articles, e.g. mattresses, comprises an open framework 1 resiliently supported at 8, 9 and 10, capable of being vibrated by an -electric motor 12 -with an eccentrically loaded shaft and surrounded by a bellows-like -sealing frame 17 so that it effectively divides a chamber 13 into two parts 18 and 19. An electrically driven fan 21 sucks outside air through the filter 24 and forces the filtered air through a conduit system, by means of which it may be led into the chamber either through conduit 30 in the top of the chamber or through conduit 32 in the bottom (the other acting as an exhaust path). An electrically heated reservoir 56 of liquid disinfectant communicates with the conduit system for the addition to the air stream of the disinfectant (see Fig. 3, not shown). In operation, a mattress or the like is placed on the framework 1, the lid 16 is closed and the apparatus (which may be automatically programmed) is actuated and the motor 12 vibrates the framework 1. At the same time, air from the surrounding atmosphere flows through conduit 30 and through the mattress, carrying dust and dirt with it into the lower part 19 of the chamber. In the next phase, ingress of outside air is prevented, the disinfectant is heated and mingles with air circulating through the apparatus (and thus through the mattress). For completeness of disinfection, the direction of the air flow may be reversed. At the end of the disinfecting period, ambient air is again allowed to circulate to dry the mattress and remove traces of disinfectant.

Abstract: 872,124. Charging with static electricity. TELEFUNKEN G.m.b.H. July 9, 1959 [July 12, 1958], No. 23677/59. Class 35. [Also in Groups XXXVIII, XL (a) and XL (b)] In an electrostatic tape recorder, particularly for recording television signals, longitudinal or transverse tracks are produced on an optically transparent insulating tape 1 by first recording them on a semi-conducting layer 5 on a conducting drum 4 and then printing them on to the tape by the application of suitable potentials therebetween. The layer 5 is charged by polarizing means 6 and is bombarded by an electron stream 10, modulated by the signal and deflected by a sawtooth waveform applied to coils 12, where transverse track are required. The bombardment affects the conductivity of the layer so that by the time the tape, which has been oppositely polarized by means 8, meets the layer, a charge pattern, representing the signal, is set up on the layer to print on to the tape during the relatively long time that contact is maintained. The material of the layer, which may consist of such materials as CaF 2 , Al 2 O 3  or SiO, and the timing of the apparatus are such that the semi-conductivity of the layer has decayed by the time that the layer arrives at the polarizing means 6 on its next revolution. The charges on the tape may be subsequently " fixed " by dusting with a suitable material to produce variable-density tracks for optical reproduction.

Abstract: 1,224,942. Dideoxyzearalane. COMMERICAL SOLVENTS CORP. 12 May, 1969 [15 May, 1968], No. 24119/69. Heading C2C. [Also in Division A5] Dideoxyzearalane of the formula may be prepared by lactonizing 2-(10-hydroxy undecyl)benzoic acid with a cyclization agent X.CO.Y, where X is -Cl or -Br, Y is -Cl, -Br, or -OR, and R is lower alkyl. The intermediate 2 - (10 - hydroxyundecyl) benzoic acid may in turn be prepared from 10-undecenoic acid anhydride by condensation with phthalic anhydride to produce 3-(9-decenylidene) phthalide, reduction of the internal double bond of the latter with NaBH 4 , hydration of the terminal double bond of the resulting 3-(9-decenyl) phthalide e.g. using mercuric acetate and then NaBH 4  demercuration, followed by saponification of the 3-(9-hydroxydecyl)-phthalide and hydrogenolysis of the resulting 2-(1,10-dihydroxyundecyl) benzoic acid. The lactonization is preferably effected in the presence of an HX acceptor, e.g. a tertiary amine, and an organic solvent having from 1-10 carbons, particularly benzene. The racemic dideoxyzearalane may be resolved by conventional methods. Examples detail the preparation of dideoxyzearalane by the above synthesis and also of (+) - dideoxyzearalane from zearalane via O,O di - (2 - benzoxazolyl) zearalane. (+)- Dideoxyzearalane is also saponified to (+)-2- (10-hydroxyundecyl) benzoic acid and then relactonized without racemization. 10-Undecenoic acid anhydride is prepared by refluxing the corresponding acid with acetic anhydride.
