Abstract: 1,124,192. Insoles. J. ANTELL. 14 July, 1965 [16 Sept., 1964; 4 Feb., 1965], No. 29966/65. Heading A3B. A method of making a shoe comprises placing an auxiliary sole on a last, laying an insole over the auxiliary sole and releasably attaching it to a portion only thereof, and attaching the margins of a lasted upper to the insole. A later removal of all or part of the auxiliary sole adapts the size of the shoe to, fit the foot. In the shoe shown in Fig. 7 the auxiliary sole 30 is coated with pressure-sensitive or contact-actuated adhesive on both pairs and protected by backers 31, 32, and has a skived uncovered rear margin by which it is attached to the shoe between the insole 33 and sock 37. Depending on the fit of the shoe the backers are removed and the auxiliary sole stuck to the insole and sock, or the auxiliary sole is removed and the insole and sock stuck together. Alternatively a heat or solvent actuated adhesive may be used. The auxiliary sole may cover the forepart only, or may be full length. Fig. 14 illustrates a multi-layer sole with backers 53-56, tapered upward margins 50a, 51a, 52a, and the sole layers graduated  in width and length with layer 50 the smallest. One, or more, or all the layers 50, 51, 52-may be removed. The upper surface of the auxiliary sole may be finished in the manner of a sock lining. An auxiliary sole for shoes having a pronounced arch comprises layers shaped to a last bottom and skived at the front and rear margins which are later attached to the insole. For use with shoes having pointed toes the layers are cut short at the front. The soles may be blanked out from a continuous strip formed of a strip 85, Fig. 22, of leather &c. skived at both edges, a layer 86 of double-faced adhesive tape, and a backer 87, and moulded to the shape of a last bottom.

Title: Improvements in or relating to slide rule cursors
IPC: G06G1/02
Filed: 1953-11-02
Abstract: 743,826. Calculating-apparatus. LOWSON, K. Feb. 1, 1955 [Nov. 2, 1953], No. 30203/53. Class 106 (1). For indicating the position of the decimal point in slide-rule calculations, a slide-rule cursor carries a relatively movable member, and the member and the cursor body are formed or marked with co-operating pairs of scales, for use in multiplication and division respectively, each comprising equally spaced figures representing powers of ten from negative values through zero to positive values. The co-operating scales for multiplication increase in opposite directions while those for division increase in the same direction. The figures representing negative powers may be of a distinguishing colour. As shown, the cursor body is formed with a circular depression to receive a ring which is retained by, and rotatable on, a central disc cemented to the body and formed with a cursor hair line against which the decimal point location is read on the ring after the latter has been set by aligning appropriate figures for the two factors involved. In the event of a right-hand displacement of the slide in a calculation, the ring must be rotated by one additional step. The parts are formed by injection-moulding clear plastic, the ring being formed with notches 11 for engagement by an upper limb 9 integral with the normal spring which bears on the slide-rule stock. Alternative constructions are described in the Provisional Specification, which also states that two alternative indices may be provided on the fixed part to avoid the additional unit displacement of the slide referred to above.

Filed: 1946-10-10
Abstract: 617,822. Pattern-grading machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BURTON, S. Oct. 10, 1946, No. 30219. [Class 97 (iii)] Means are provided whereby operative connection between each pantographic lever and its associated slide may be severed at will in order that the pantographic levers may be adjusted without affecting the positions of the model-guide pin or the pattern material. As applied to a machine of the kind described in Specification 335,200, [Class 97 (iii)], the width pantographic lever 3, Fig. 1, pivotally mounted at the width pantographic centre 7, is pivotally connected to the width slide member 11 by a stud 19 whose upper end projects into a small auxiliary slide 23 which is normally held rigid with a plate 25 secured to the slide member 11, but which may be released for movement along and parallel to the plate 25 when desired. The auxiliary slide 23 is retained in a guideway 31 in the plate 25 by plates 32 secured to the plate 25 and is clamped in position by a foot 35 mounted on a threaded non-rotatable stem 39 carrying a clamping nut 43. A second clamping nut 53 is mounted on a non-rotatable stud 45 having a head 49 and a sleeve 47 which serve to bind together the bar 27 of the width slide member 11 and the guideway 29 on which it is normally free to travel. The length pantographic lever 5 is similarly connected by a stud 21 to an auxiliary slide 55 which is normally clamped to but may be released from the length slide member 13 by similar clamping means 57, 59. Operation of a clamping nut 71 serves to clamp the slide member 13 to the guideway 61 mounted on the width slide member 11. For normal operation the auxiliary slides 23, 55 on which the pantographic levers are mounted are clamped to their respective slide members 11, 13 which are free to move on their guideways. If the position of the pantographic levers is to be adjusted, the width and length slide members are clamped to their guideways and the auxiliary slide members released so that the levers may be re-positioned without any consequential movement of the main slide members. Specifications 364,550 and 416,581 also are referred to.

Title: Process and apparatus for balancing rotors
IPC: G01M1/30
Filed: 1958-09-23
Abstract: 903,729. Milling. AVERYS Ltd., W. & T. (Shenck Maschinenfabrik G.m.b.H., Carl). Sept. 23, 1958, No. 30295/58. Class 83 (3). [Also in Group XIX] In a process for balancing rotors the unbalance is first determined both in magnitude and angular position, the workpiece is then located relative to a correction tool in accordance with these measured values and correction is effected by cutting in a single direction a continuous arcuate groove of length proportional to the magnitude of the unbalance and extending symmetrically on either side of the angular position of unbalance, the groove being of predetermined constant width and depth. The position and amount of the dynamic unbalance of the rotor are measured on suitable apparatus (not shown) and indicated on a screen 1. The operator then transfers the rotor to a milling tool 14, where it is located on a shaft 26d, Fig. 3, by a spring-pressed centre 26e having a key 4. He then turns dials 22a, 23a in sequence through angles proportional to the position and magnitude of the unbalance, and these act to turn the shaft 26d, first so that the point to be machined is opposite the tool, and then through a further angle proportional to half the magnitude of the unbalance. The rotor is then milled, a groove of constant depth being cut as determined by rings 18e, 18f, Fig. 2a, held against the work by spring means. The milling tool is then automatically released from engagement with the rotor, by the action of a series stepping switch which has been set during the positioning of the rotor. Specification 756,168 is referred to.

[Also in Division G6] A vessel has a plurality of inlet-outlet connections each controlled by a valve and a common selectively operable valve actuating mechanism is provided. A vessel 1, e.g. the chamber which collects the coolant in a nuclear reactor, has a plurality of inlet and/or outlet conduits 2 each containing a valve comprising a body 5 and a valve member 6. The valve member 6 is screw threaded at one end so as to be adjustable by rotation of a lug 9. A common actuator pin 10 is carried by a hollow shaft which is axially and rotationally adjustable for selection of the valve to be operated. The hollow shaft 11 extends through the wall of the chamber 1 and passes through a sealing structure 12 and through a biological protection shield 13 into a control chamber 14. For balancing purposes the other end of the shaft 11 projects out of the chamber 1 into a cylinder 23 which is maintained at atmospheric pressure. Within the tube 11 is a tube 25 containing an endoscope device 24<SP>1</SP> and an illuminating device 24 whereby the position of the actuating pin may be viewed through eye pieces 26 by the operation within the control chamber 14. A television camera may be used instead. The operating mechanism comprises a cage 30 rotatably connected to the shaft 11 and mounted on two stationary screwed rods supporting, within the cage 30, nuts 32 which are rotatable by a handle 34 to effect axial movement of the shaft 11. Rotation of a second handle 35 effects rotation of the shaft 11 through gearing. The positions of the valve members 6 may be directly indicated by synchronously driven screws outside the chamber 1. The pin 10 may actuate a switch in an electric warning circuit on excessive movement of the valve member.
Patent GB-304156-A (GB)
Abstract: 304,156. British Celanese, Ltd., and Haney, C. I. July 15, 1927. Acetic and other aliphatic acid anhydrides are produced by mixing the acid (as spray or vapour) with an inert gas such as steam, superheated steam, nitrogen or hydrogen heated to a sufficient temperature such as 600-1200‹ C., the acid being preferably preheated to 150-300‹ C. The anhydride may be separated by fractional condensation or by passing through a solvent of higher boiling-point than water and preferably higher than the anhydride, such as chlorbenzenes, benzyl ether, tetrachlorethane, acetins, anisol, pcresyl acetate, phenetol, paraffin oil, or mixtures of such substances; or by means of an entraining liquid as described in Specification 303,772, or by means of a cooled extraction liquid as described in Specification 298,667, or by passing over a water-binding substance as described in Specification 289,972. In an example, acetic acid is vaporized in a still 1 and passes by a pipe 2 to the outer space 3a of a heat-exchanger 3 to heat it to 200-300‹ C. and thence to a reaction vessel 5 which may be of copper, earthenware or the material sold under the Registered Trade Mark " Vitreosil," superheated steam at 800- 1000‹ C. being added by a pipe 6. The acetic acid supply is controlled by a valve 7 so as to obtain a temperature of 500-800‹ C. for the mixture. The vessel 5 has baffles 8 to ensure good mixing. The gases pass out through a pipe 9 to the inner space 3b of the heat-exchanger 3 so as to be cooled to 200-300‹ C. and then by a pipe 10 into an " extraction liquid " as described in Specification 298,667. The acid employed may be dilute.

Abstract: 836,166. Change-speed control. GENERAL MOTORS CORPORATION. Oct. 2, 1957 [Oct. 29, 1956], No. 30830/57. Class 80 (2). [Also in Group XXIX] Upon depressing a motor vehicle accelerator pedal 34, a plunger 26 moves a metering valve closure 26 through a spring 30 whereby an inlet 18 is placed in communication with an outlet 24, which latter is connected via a restriction 41 with a space behind the right-hand end of the closure that is in series with a chamber 38 in which is a fixed or adjustable spirally-wound bimetallic thermal-element 50 having an extension 54 engaging the righthand end of the closure 26. The fluid in chamber 38 urges the closure against the spring 30 until the inlet 18 is blocked and, if the pressure is great enough an exhaust port 22 is opened, otherwise both the inlet 18 and port 22 remains closed until the pressure falls and the inlet is reopened. If the fluid is cold, the element 50 also loads the closure 26 against the spring 30; as the fluid temperature rises this bias is reduced until at a given temperature it is completely removed. The pressure in the outlet 24, which is determined by the resultant of the force of spring 30 and the opposing forces of the fluid in chamber 38 and the element 50, acts upon another valve, not shown, in opposition to a speed-responsive pressure, the other valve controlling the servomotor of a step-ratio variable-speed transmission mechanism, not shown. The inner end of the element may either be positioned in a slot 48 incorporated in a post 46 attached to the valve body or in frictional engagement with the post. The spiral element 50 may be replaced by one of hairpin type.
