Title: Improvements relating to the control of electrically propelled road vehicles
IPC: B60K1/00
Filed: 1923-05-03
Abstract: 214,093. Garrett & Sons, Ltd., R., and Collins, A. E. May 3, 1923. Hand -actuated gear for operating brakes and switches, arrangements of; controlling levers associated with hand steering- devices; unshipping steering hand-wheels; steering- gear.-In electric vehicles means are provided, in addition to the ordinary controlling gear, for steering and controlling the vehicle from either side so that the driver can walk alongside and control the vehicle for manoeuvring purposes. The steering hand-wheel 1 may be secured by a screwed arm 8 on the ordinary steering- shaft 7 or on an auxiliary transverse shaft 14 geared thereto. The shaft 14, which may extend right across the vehicle, is geared to the shaft 7 by means of gearing 27, Fig. 3, a shaft 28 and gearing 29. The main controller 6 is actuated by a hand-lever 5 mounted on the steering column and connected to the controller by a tubular shaft 25 and gearing 24. An auxiliary controller 18 with a handle 19 is provided at the side of the vehicle, a switch (not shown) being arranged to ensure that only one controller at a time is active. In addition to the usual hand-brake lever 11 and a foot-brake lever (not shown) an auxiliary brake-lever 16 is mounted at one or both sides of the vehicle, this lever 16 being connected to the foot-brake mechanism through lost-motion connections so that either the lever 16 or the foot lever can operate the brake without affecting the other lever. 214,102. Whitehead, H. May 15, 1923. Brakes.-A brake drum is fixed on the rear end of the propeller or worm shaft of a Ford truck chassis, and is engaged by internal or external brake members. The worm shaft A carries a brake drum L the boss of which fits in a thrust bearing C replacing the usual thrust bearing between the shaft A and the axle casing B. Hardened steel rings K, J take up the forward and rear worm thrusts respectively. Pivoted brake shoes P are expanded by means of a bell-crank lever A<1> acting through a rod C<1>, a shaft S and links R, the lever A<1> being actuated by the usual foot-brake pedal which is disconnected from the usual transmission brake. In a modification, pivoted semi-circular blocks enclose the brakedrum, and are actuated in a similar manner to the blocks P. A fixed plate N carrying the brake mechanism is secured to the axle casing by means of screws O and G'.

Title: Improvements in speed- and torque-change devices
IPC: F16H37/08
Filed: 1951-05-23
Abstract: 700,783. Variable-speed gear. LIONS, J. P. V. May 23, 1951 [May 24, 1950] No. 12042/51. Class 80 (2) A change-speed device comprises in combination an input and an output shaft, a transmission between the input shaft and an intermediate shaft including two trains of adjustable groove-width sheaves in series and connected by trapezoidal belts having a width-to-thickness ratio greater than three, and planetary gearing associated with the said three shafts, the connections between the individual components of the planetary gear and the shafts being chosen to suit the variations in velocity ratio required. The use of trapezoidal belts of relatively large width-to-thickness ratio enables a greater change in velocity ratio to be obtained from the adjustable groove-width sheaves than with narrower belts of the same thickness. As shown, a constant-speed driving shaft A is connected to the rotatable planet carrier 4 of a planetary gear and also carries an internally toothed annulus 7 meshing, through pinions 8 rotatable on fixed supports 9, with a gear 10 on a hollow shaft 11, integral with the outer flange of an expanding belt-pulley E<SP>1</SP> which transmits drive to the internally toothed annulus 5 of the planetary gearing through expanding pulleys E<SP>2</SP>, E<SP>3</SP>, E<SP>4</SP> and a hollow shaft B. The inner flanges of the expanding pulleys E', E<SP>4</SP> are moved by a lever 3 actuated by a governor device or the like to change the velocity ratio of the belt gearing. The external flanges of the pulleys E<SP>2</SP>, E<SP>3</SP> are connected and are moved automatically by change in the tension of the belts simultaneously with the movement of the inner flanges of the pulleys E<SP>1</SP>, E<SP>4</SP>, the belts being of trapezoidal cross-section and having a width-to-thickness ratio greater than three, and being kept in tension by spring-loaded pulleys. Variations of the speed of rotation of the annulus 5 causes the sun gear 6 and output shaft C of the combined gear to rotate at different speeds. In one modification, Fig. 9 (not shown) the carrier 4 of the planet gearing is connected to the output shaft C and the gear 6 is mounted directly on the input shaft A. In other modifications, Figs. 4-7 (not shown) the gearing 7 ... 10 is dispensed with, the expanding pulley E' being secured directly to the shaft A, various connections between the shafts A, B and C and planetary gearing being shown, including such gearing using stepped planets. In explanatory Figs. 1-3 (not shown) of known art, gearing is shown comprising a train of toothed gears in series with a single train of expanding pulley gearing to drive the toothed annulus of a planetary gear of which the planet carrier is driven directly by the input shaft; the expanding pulley gearing can be replaced by hydraulic, friction, electric. &c. change-speed gearing.

Filed: 1941-09-19
Abstract: 554,826. Glucose purifying saccharine liquids. CORN PRODUCTS REFINING CO. Sept. 19, 1941, No. 12170. Convention date, March 24. Addition to 354,823. Drawings to Specification. [Class 127] In the treatment of starch-conversion liquors for the removal of acid as described in the parent Specification, the liquor is first treated with bentonite or similar clay to remove colloidal matter. It may also be treated with activated carbon to remove colouring matters. In addition soluble salts may be removed by passage through hydrogen-ion exchange material, which results in the formation of acid which is later removed. Suitable hydrogen-ion exchange materials are insoluble organic compounds in which a high molecular weight alkyl, aryl, aralkyl or heterocyclic radical is attached to a sulphuric, hydrogen sulphate, phosphoric or hydrogen phosphate radical. When passing the liquor through a fresh or freshly regenerated bed of acid-removing material, the liquor will come out alkaline. The alkalinity is reduced to prevent decomposition of dextrose by adding to the treated liquor a small proportion of the untreated liquor. Specifications 232,160 [Class 127], and 489,937 also are referred to.

The casing may be formed in two longitudinal sections, one of which is hinged to the other, the latter being fixed to the axis. The axis may be hollow and provided with holes for the admission of water to the cylinder.

Abstract: 552,032. Flexible hose; knitting. FIDELITY MACHINE CO. Oct. 3, 1941, No. 12782. Convention date, Oct. 4, 1940. [Class 99 (ii)] [Also in Group VIII] A flexible hose, applicable for automobile heating, defrosting and air-conditioning apparatus, vacuum cleaners, speaking tubes &c. consists of a seamless circular-knit tube having successively interknit stitch courses a, a<SP>1</SP> and a resilient wire w incorporated in some of the courses and constantly tending to twist the tube circumferentially about its axis. The interstices of the knitting thus tend to close and it can readily be impregnated with an elastic filler to render it air and sound proof. As shown, the stitch courses form stitch wales c on the outer surface and alternating stitch wales d on the inner surface, the wire w being laid in the courses a<SP>1</SP> between the outside and inside wales. The tube is drawn from the knitting machine by belts 2, Fig. 7, beyond which the tube is free to be twisted helically by the wire w, reducing the size of the interstices. The tube may then be waterproofed by impregnation with a liquid latex by spraying or dipping, and an outer cover may be braided or otherwise formed on the tube. Instead of the wire w, a strand of reed or of twisted paper impregnated with a synthetic resin may be employed. In order to form a corrugated tube, an elastic rubber cord or ribbon may be incorporated in intervening stitch courses. Free courses may be left between the courses containing the wire and rubber strands.
