Title: Improvements in or relating to the conforming of shoe uppers to the shapes of appropriate lasts
IPC: A43D21/18
Filed: 1954-06-10
Abstract: 767,740. Pulling-over machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and FREER, C. H. June 9, 1955 [June 10, 1954], No. 17029/54. Class 17 (1). Gauging devices 10 are provided in a pulling- over machine at different positions around the toe and moved by the operator into close relation with different portions of the upper to give an indication, at the outside of the upper and in the vicinity where the grippers exert their pull, of the heightwise positions of such parts with relation to the bottom face of the shoe bottom member, and thus enable the operator to adjust the pulling action if the indication is that the upper is not correctly positioned. The Rex type machine illustrated has a shoe rest 2, toe and side grippers 4, tackers each comprising a tack block 6 and driver 9, clamping devices (not shown), a heel rest (not shown), and wipers 20. Each gauge member comprises a U-shaped metal strip 12, 18 with the ends of the limbs bridged by a tie bar 14. The limbs slide in grooves 16 in the tack blocks in planes substantially parallel to the bottom of the shoe, and frictionally grip the block. In operation on a mudguard type shoe, as shown, the margins of the upper are introduced into the jaws and the latter closed and moved to tension the upper. In the following pause gauges 10 are moved inwardly, relatively to blocks 6, until the cross pieces 18 engage the upper U, and indicate whether the seam S connecting the cover strip to the upper occupies the desired position with respect to the feather line. Action of the grippers is then adjusted if necessary. During the second stage of operation the heel rest and clamping devices engage the shoe, the wipers wipe the upper margins, and the tacking devices swing over the shoe bottom, the gauge members being returned by engagement with the upper. The gauging devices may also be incorporated in inverted type pulling-over machines. Specification 12304/03 [Class 17] is referred to.

Abstract: 403,382. Universal joints. STANDAGE, C. A. G., 66, Redcliffe Gardens, South Kensing- ton, London. June 16, 1932, No. 17090. [Class 80 (ii).] In a flexible universal joint of the kind having axial, preferably laminated, blade-springs 9 carried by, and capable of limited flexing movement on, one member 1, and centrally engaged by teeth on the other member 10, the said teeth are formed by flat or convex-walled axial slots in bearing-pieces 12 rotatable about radial axes in slotted sockets 11 in the member 10. Alternatively, the teeth may be in the form of rotatable cylindrical rollers or simply convex-walled slots in the member 10. The springs 9 are supported at their ends in slots 8 in a sleeve 5, preferably divided transversely to the coupling axis into two parts having a toothed connection 6, and the slots 8 are stepped or smoothly widened towards their centre to allow a limited spring movement. In the form shown in Fig. 1, the springs 9 are held in radially against inner flanges 4, 15 by inclining the ends of the springs 9 and slots 8. In modifications, the springs are held in radially by spring rings fitting external grooves in the springs 9 and sleeve 5, the spring ends being either perpendicular or outwardly inclined, or by projections fitting grooves in the ends of the springs. The coupling permits relative axial movement of the coupled members, which are centred on each other, in the form shown in Fig. 1, by engagement of the part-spherical periphery of the member 10 in the sleeve 5, or, in a modification, by a split socket in the member 10 engaging a ball which has a cylindrical extension slidable in the member 1. The sleeve 5 is attached to the hub-member 1 by axial bolts. A cover-sleeve 3 and spring- pressed packing-ring 14 are also provided. The coupling may be used in the differential gear in the driving-axle of a motor vehicle or in the cardan shaft. Specification 348,506 is referred to in the Provisional Specification.

Title: Improvements in or relating to the water tanks, fuel bunkers or the like of locomotives
IPC: B61C17/02
Filed: 1952-06-18
Abstract: 723,321. Locomotives. BEYER, PEACOCK & CO., Ltd., and HADFIELD, J. June 18, 1952 [July 19, 1951], No. 17168/51. Class 79(1). In a locomotive or tender having a water tank, fuel bunker or like container mounted on its supporting structure, the structure while providing a firm seating for the container permits upward movement of the container from the seating at all points but prevents movement of the container, either longitudinally or laterally, horizontally relative to the seating, and spring means are provided for biasing the container down onto the seating whereby distortion of the structure is not transmitted to the container. As shown'the invention is applied to an articulated locomotive, Fig. 1. The boiler D of the locomotive is pivoted at each end at F to a wheeled frame A on which is supported the fuel or water container C. At the front end the frame A carries a bracket G and at each side near the rear end a bracket H. The bracket G carries a rail 1, Figs. 5 and 6, having widened portions between ribs 8, the widened portions carrying plates 7 on which are formed ribs 9. The ribs 8, 9 prevent horizontal longitudinal movement between the rail 1 and plates 7 which are welded to plates 6 welded to the bottom 2 of the tank C and its extension 2a, wood spacers 11 being provided between the plates 7. The end wall 3 of the tank is supported by inner and outer angle section lengths 4, 5. The heads 12 of bolts 10 engage the length 5. The bolts pass through extension 2a, the plates 7, the rail 1 and are held in position by nuts 14, compression coil springs 13 being arranged between the nuts and rail to provide the spring bias. Each side mounting, Fig. 8, comprises a supporting rail 15 secured to the bracket H. A bolt 23 and spring 25 connects the rail to a casting 18 which is welded to a plate 17 in turn welded to the bottom edge of the tank C. A plate 21 welded to the casting 18 carries a rib 22 which in combination with a similar rib on the other side mounting prevents the horizontal lateral movement between the tank C and frame A. Applied to a tender, Fig. 4 (not shown) the mounting of a tank on the frame thereof is attained by a rear mounting and side mountings similar to that shown in Figs. 5, 6 and 8.
Patent GB-664721-A (GB)
Title: Process for the manufacture of pure folic acid
Filed: 1949-06-29
Abstract: Folic acid is obtained by subjecting a solution of crude synthetic folic acid in form of its formyl derivative to purification in a manner known per se and hydrolysing the pure formyl folic acid obtained.  The word "known" as used in relation to the manner of purification indicates those methods of purification which are in actual use or described in the literature for the separation from accompanying impurities of chemicals capable of being crystallized. The purification may consist in the fractional precipitation of the formyl derivative with ether from a solution of the crude material in formic acid and hydrolyzing the pure formyl derivative with aqueous sodium hydroxide at room temperature.  The formyl derivative may be extracted from the crude material with a mixture of ether and formic acid, or the crude material may be subjected to fractional crystallization, e.g. with water.  Two examples are given.  The sample furnished under the provisions of Sect. 2(5) comprises folic acid which is obtained by the fractional crystallization of the crude formyl derivative in glacial acetic acid, followed by hydrolysis of the formyl derivative.  Formyl folic acid of the formula <FORM:0664721/IV (b)/1> is prepared by formylating folic acid or by the condensation of pteridylaldehyde and p-aminobenzoylglutamic acid in the presence of formic acid.

Title: Automatic feed control apparatus for band saws
Inventor: CRANE ROBERT LEWIS
IPC: B23D55/04
Filed: 1956-06-04
Abstract: 818,816. Automatic control systems for machine tools. CONTINENTAL MACHINES Inc. June 4,1956, No. 17198/56. Class 38 (4). [Also in Groups XXIII and XXXVIII] An automatic control for band saws (Group XXIII) consists in providing for the feed of the work into the band saw to be produced by mechanism powered by a prime mover 11, Fig. 1, which is governed by the strain imposed by the thrust of the work against the tool. In order to measure the strain as the work is fed against the saw, the latter is urged against a roller 17 fitted in a saw guide 16 attached to a vertically-adjustable back-up post 14. The post is weakened at 14<SP>1</SP>, Fig. 5, to accommodate two oppositely-disposed electromagnetic strain gauges 18 which are connected across the corners 22, 221 of a rectifier bridge 23, Fig. 2, so that deflection of the post caused by the work feed results in a nett current flow to the meter. If desired, only one strain gauge need be provided and the output of this gauge is then compared with that of a comparison gauge at a remote point. Strain gauges of the resistance type may also be used in place of the electromagnetic gauges. In order to overcome side drag on the saw, deflectable back-ups 50, 51, Fig. 11, are mounted both above and below the work zone on posts 14, 14<SP>1</SP>. Saw guides 15, 151 are fixed to the free ends of arms 58, 581 which are hinged to the supports 14, 141, the thrust of the saw guides being transmitted through a conical boss 61 projecting from the arm 58 to the upper back-up 50 and the resultant deflection of this back-up is communicated to a strain gauge 18. The lower back-up 51 may also carry a strain gauge, but should this not be the case, the thrust applied to the lower saw guide 15<SP>1</SP> is cushioned by interposing a spring 70 between the back-up and the arm 581.

Filed: 1940-12-04
Abstract: 545,631. Cash registers. KOOPERATIVA FORBUNDET FORENING, U. P. A., and DAHLBERG, T. O. R. Dec. 4, 1940, No. 17232. [Class 106 (i)] In a machine as described in Specification 547,147, the main drive shaft is locked against release unless the differential segments are in the zero or certain chosen positions. The wheels 22 with which the differential segments 11 are in mesh are provided with a flange or cam on one face which is cut away in the example shown at two places diametrically opposite. At these places, the spring pulled lever 23 can take up the dotted line position in which its pin 24 can enter a gap in the flange to engage the wheel teeth. This permits the bail 72 carried by arms 73 to move down under the influence of its spring and the arm 71 away from the path of a pin 69 on the disc 68 thus permitting counterclockwise rotation of shaft 12. In other positions of the differential segments the pin 24 rides on the cam, and the hook 79 engages under bail 72 preventing its movement.

Title: Improvements in or relating to polyurethane foams
IPC: C08J9/00
Filed: 1965-04-23
Abstract: Polyol antimonate (III) esters may be prepared by reacting antimony trioxide or antimony trichloride with excess polyol. Examples describe the preparation of antimonate (III) esters from antimony trichloride and (i) a low M. W. polyol prepared by condensing 1,2-propylene oxide with sorbitol and (ii) dipropylene glycol in the presence of epichlorohydrin to remove the HCl formed and from antimony trioxide by reaction with dipropylene glycol. Esters from antimony trichloride and a low M. W. polyol prepared from 1,2-propylene oxide and a solution of sucrose in glycerine are also referred to.  The polyol antimonate (III) esters may be used as fire-retardants in polyurethane foam formulations (see Division C3).ALSO:Polyurethane foams are prepared by reacting an aromatic diisocyanate component with a polymeric polyol having at least three hydroxyl groups per molecule and a hydroxyl number of 350 to 650, in contact with inert fluid expanding agent having a boiling point between - 20 DEG  C. and 80 DEG  C., a surfactant which stabilizes polyurethane foam during foam formation, and up to 5% by weight of antimony in the form of a soluble polyol antimonate (III) ester, the aromatic disisocyanate component comprising a mixture of aromatic diisocyanates and having a freezing point of less than 40 DEG  C., at least one of the diisocyanates having chlorine and/or bromine as a ring substituent, said chlorine or bromine being present in an amount of at least 7% by weight, and the antimony and halogen percentages being calculated on the weight of the polymeric polyol and the diisocyanate component. Suitable diisocyanates, polyols, inert fluid expanding agents and surfactants are those which are discussed in the parent Specification. The polymeric polyols can also serve as a solvent for the polyol antimonate (III) ester The polyol antimonate (III) esters may be prepared by reacting antimony trioxide or antimony trichloride with excess polyol so that the resulting ester will have free hydroxyl groups which can react to form part of the foam.  Preferably the ester contains at least 6 hydroxyl groups for each atom of antimony introduced.  The hydrogen chloride by-product produced when SbCl3 is used may be neutralized with ammonia or amines or preferably by adding an equivalent amount of an alkylene oxide or epichlorohydrin and distilling off the product if desired.  Liquid polyols are more suitably reacted with Sb2O3 or SbCl3 but ethylene and 1,2-propylene glycol form insoluble esters and are therefore unsuitable.  Catalysts may also be added to the reaction mixture, especially tertiary amines and/or organotin compounds such as N-ethyl-morpholine, triethylenediamine, 1,3-bis(dimethylamino)-butane, dibutyltin dilaurate and stannous 2-ethylhexanoate.  The foams may be prepared batch-wise or continuously.
