Title: Improvements in or relating to the rounding and/or channelling of shoe soles
IPC: A43D43/02
Filed: 1933-07-29
Abstract: 423,364. Shoe - making. B R I T I S H UNITED SHOE MACHINERY CO., Ltd., and BAGSHAW, C. M., Belgrave Road, Leicester. July 29, 1933, No. 21335. [Classes 17 (i) and 17 (ii)] Trimming; channelling.-Relates to shoes having an English channel at the fore-part and in American channel at the waist, and consists in making an English channel all round the sole from breast edge to breast edge while leaving an excess of width at the waist portion, trimming off this excess to convert the English channel opening on the tread surface to an American channel opening at the edge of the sole at this portion, and simultaneously deepening the cut and also, preferably, removing a wedge-shaped section from the surface of the channel. The first operation may be performed in a rounding and channelling machine of the kind described in Specification 13301 /10, [Class 17 (i)], adjusted to channel at a uniform distance from the sole edge and leave excess material at the waist. A second similar machine may be modified to facilitate the second operation. The usual treadle rods 51, 53 which retract the sole support for the insertion of work and raise the crease guide, respectively, are connected by a lever 55 pivoted to the rod 51 and engaging a collar 61 on the rod 53, this rod, only, being provided with a treadle. A strong spring 99 urges the rod 51 downwards, so that the sole support is normally urged to the retracted position, the rod being pivoted to a bell-crank lever 63 engaging a lug 71 on the slide carrying the support, a hand lever 65 moving with the bell-crank lever co-operating with a stop 105 for determining the rearward position of the support. The rod 53 carries a collar 107 actuating a lever 111 described in the prior Specification. Depression of this rod causes rise of the sole support and crease guide. The usual channelling knife is substituted by a U-shaped knife 43 with a curved end adapted to deepen the channel and also remove a wedgeshaped section of leather from the under side of the surface of the original channel, so that after the sole has been secured by stitching in the channel and the channel closed the sole may present a thin edge at the waist. In this second machine, the fore-part guide is not used and should be removed. The trimming knife 39, sole support 41, feed plate 45, crease guide 47, and sticker point 49 are of usual construction except that the slot 85 for allowing rock of the sole support is shorter than usual. Specifications 3497/96, [Class 17], 315,812 and 322,198, [both in Class 31 (i)], also are referred to.

Title: Three-phase ferro-resonance type voltage regulating device
IPC: G05F3/06
Filed: 1962-06-04
Abstract: 1,009,857. Ferro-resonant circuits. YAWATA IRON & STEEL CO. Ltd. June 4, 1962 [July 20, 1961], No. 21468/62. Heading H3B. A three-phase voltage regulator of the ferroresonant type comprises three linear reactors 2, 3, 4 connected between an alternating source 12 and a load 13, taps on the reactors being connected to taps on three saturable reactors 6, 7, 8 connected across respective tank condensers 9, 10, 11. The saturable reactors have a common core 5, the legs of which have a non- uniform cross-section. Because of this variation, part of each leg saturates before the rest. It is shown in the Specification that by suitable choice of the shape of the magnetization curve in the saturation region, which depends on the cross-section of the legs, third harmonic distortion may be eliminated from the output. The circuit acts as a voltage regulator as the impedance of the ferro-resonant circuit is very voltage sensitive and a slight change in voltage causes a large change in current, thus changing the voltage across the linear reactance 1.

Title: Improvements relating to artificial limbs
IPC: A61F2/64
Filed: 1919-09-02
Abstract: 150,901. Pringle, A., and Kirk, T. S. Sept. 2, 1919. Limbs, artificial.-Joints for artificial limbs are formed by pivoted crossed links with locking means for securing them in any angular position. Figs. 1 and 1<a> show the invention applied to an elbow-joint. Three cruciform frames a, b, c are connected by pivoted crossed links as shown. The frame a has a multiple pin-and-slot connexion with the upper arm so that it can be rotated to any desired degree on the arm and then fixed by a screw clamp, while the frame c is fixed to the forearm. By means of harness, the links can be moved from the position shown in Fig. 1 to that shown in Fig. 1<a> which represents the limit of the bending of the elbow. A curved plate p supports the clothing when the elbow is bent. To lock the joint, two of the opposed links are provided with projections having registering slots which are engaged by a slidable spring-pressed locking bar l. By positioning a projection l<2> on the bar above or below a projection m on the framing, the bar is placed into or out of action. Temporary release of the joint may be secured by moving the bar axially so that a slot in the bar registers with the projections on the links. Modified locking-means may be provided in which a pin mounted in the frame b passes through slots in two opposed links on each side of the frame. By moving the pin axially by cam mechanism, the links on each side of the frame are jammed frictionally between sleeves loosely mounted on the pin.. Fig. 4 shows a modification in which the frame a is omitted, and the frame b connected by long crossed links f<2> to the shoulder. In this case the locking of the elbow-joint also locks the shoulder-joint. Fig. 5 shows means for supporting the arm and operating the elbow-joint in the case of a shoulder amputation. The upper arm is supported by a bent rod q which rotates in three bearings s<1>, r<1>, r<2>, one being formed on a shoulder cap s, and the others supported on the back of the wearer. A forward movement of the shoulder and cap s is stated to swing the upper arm rearwardly about the pivots r<1>, r<2>, and this rearward movement causes a strap u to pull up the forearm and bend the elbow. Fig. 7 shows the invention applied to the knee-joint of an artificial leg. The lower leg framing comprises a series of oval frames w connected by pivoted crossed links, the upper pair of which form the knee-joint and the lowest pair the ankle-joint. The pivot z<6> of one pair of opposed links forming the knee-joint runs freely in a slot formed in another pair of opposed links when the leg is not supporting the weight of the body. When the weight of the body comes on the leg, the pivot z<6> is forced outwardly into engagement with one of a series of teeth in the slot to lock the joint. The joint is unlocked automatically by the extension of the links when the foot is raised from the ground.

Abstract: 458,938. Luggage theft and like alarms. GREGORY, V. H., 65, Highview Road, Ealing, London. July 30, 1935, No. 21598. [Class 118 (i)] Loss or movement of luggage on a motor vehicle is automatically signalled to the driver by the movement of a pivoted flag member i when released by the disturbance of the luggage cord h. When this cord is pulled out of a slot in a bracket member f, a spring j swings the flag i against a buffer stop k. Fig. 3 shows the flag l secured to a drum o having a pin n around which is looped the luggage cord m, so that when the cord m is pulled beyond a shroud r it is separated from the pin, and the flag is held in the warning position by a spring s adapted to release its grip when the drum is rotated in either direction. A weak spring x tends to urge the flag towards the set position. The device may be secured to the vehicle by a vacuum cup z<1> or by screws.

Title: High purity crystalline dextrose and method of manufacturing same
IPC: C13K1/10
Filed: 1927-08-19
Abstract: 300,698. Marks, E. C. R., (Corn Products Refining Co.). Aug. 19, 1927. Glucose.-In the preparation of dextrose from starch, particularly maize starch, the converted starch solution is concentrated to a crytallizing supersaturated condition and maintained in this condition by the continued extraction of water, the liquid being agitated until the desired point of crystallization has been reached. A solution containing 94 per cent or more of dextrose is concentrated in a vacuum pan to a density of from 40‹ to 49‹ BaumÚ at a temperature of from 45‹ to 60‹ C. For the production of # anhydrous, the temperature should be at the upper end of this range, preferably 58‹ C., for a hydrate at the lower end, preferably 45‹ C., and for a anhydrous at an intermediate point, 50‹ C., although as high a temperature as 55‹ C. may be used. The liquid is then seeded with dry crystals, or with a mixture of mother liquor and crystals, of the desired kind. For a anhydrous, with a purity of 94 per cent in the original solution, a a temperature of 55‹ C. and a density of 45‹ BaumÚ, half one per cent of seed crystals may be employed. With an initial purity of 97 per cent or more the seed employed need only be a trace or none at all, and the temperature may vary from 50‹ to 45‹ C. with a reduced density of 43‹ Baume. Should the viscosity be too great by reason of impurities, the amount of seed crystals should be increased or a greater agitation produced by the use of stirrers &c. When the desired quantity of crystals has been induced, further formation of crystals is prevented by the introduction of fresh liquor and the boiling is continued only rapidly enough to ensure circulation and the growth of the crystals present to the desired size. As the solid phase increases, the boiling may be more rapid, the concentration of the mother liquor and the maintenance of temperatures favourable to the formation of a anhydrous may be disregarded, and the vacuum may be increasod ; liquors of lower purity may also be introduced. At the end of the operation, the liquor is discharged from the vacuum pan and centrifuged to extract the crystals. Should the rate of crystallization be slow or the viscosity of the liquid be high, the massecuite may be treated in known manner, involving the lowering of the temperature, in a crystallizer.
