Title: Improvements in supports for vehicles
IPC: B66F7/24
Filed: 1923-05-14
Abstract: 214,475. Hancock, J. E. May 14, 1923. Stands or supports.- In means for supporting a vehicle by its axles with its tyres clear of the ground, a cradle is mounted on abase so that it may move with the vehicle from a lower to an elevated position. The cradle is constructed with side. members 26, cross members 27, 28, 29, and axle supports 42, 50. The base consists of inclined side members 11 having rollers 20 which support the side members 26 of the cradle. Rollers 31 are carried at the lower end of the cradle. A vehicle is driven over the cradle until its front axle abuts against the stop lugs 43 and carries the. cradle forward thereby raising it until the vehicle wheels are lifted clear of the ground and the cradle overbalances about the rollers 20 when the arm member 27 rests upon blocks 14 on the base. The front axle is retained in position on the front supports 42 by the shoulders 46 of pivoted latches which are held in the operative position by trip levers 48 engaging under their ends. These levers 48 are tripped by the rollers 20 as the cradle slides downwards when the vehicle is being lowered on to the ground. The height of the front axle supports 42 is adjustable. The cradle is guided by a swing guide 35 which is secured by a bolt 36 to the cross bar 16 of the base and passes through holes in the cradle cross members 27. 29. The front end of the guide 35 is guided vertically by a guide cage 37. To lower the vehicle, the end of the guide 35 is lifted thus tilting the end of the cradle which runs down on its rollers, tripping the lever 48 and releasing the front axle during the movement.

Abstract: 738,081. Charging and discharging batteries. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 2, 1953 [May 22, 1952], No. 13017/52. Class 38 (4). [Also in Group XXXVII] An electric battery charging circuit, e.g. as used in a vehicle lighting system, having contactor contacts CIC/1 for connecting the battery 1 to a charging generator 2 whose output voltage varies during operation, has for controlling said contacts means responsive to the generator voltage but incapable by itself of closing the contacts within the generators working range acting in conjunction with means responsive to current flow in the charging direction through a circuit shunting said contacts to close said contacts when and only when the generator voltage exceeds the battery voltage ; also provided are means to open the contacts CIC/1 in response to reverse current flow therethrough, and means in said. shunt circuit to prevent reverse current flow therethrough. As shown, on attaining a given generator voltage which generally is below the minimum expected of the battery, a reverse current relay voltage coil RCR/V closes its normally open contacts RCR/1 and RCR/2 to energize a polarised coil CIR of a cut-in relay which then closes its normally open contacts CIR/1 to permit energization of the main contactor coil CIC which closes its contacts CIC/1 to-commence charging. Closure of the latter contacts effectively short-circuits the coil CIR so that the cut-in relay drops out but the contactor remains energized through its maintaining contact CIC/2. When the generator voltage falls below that of the battery reverse current through the coil RCR/C de-energizes the reverse current relay which drops out the main contactor. In another embodiment, not shown, a further current coil on the reverse current relay replaces the cut-in relay. The reverse current flow in shunting circuit may be prevented by a rectifier, a permanent magnet, or by additional relay contacts.

Patent GB-135362-A (GB)
IPC: B21G1/00
Abstract: 135,362. Goldberg, S. H. Jan. 10, 1919. Pins, dress and like.-In machines for forming hairpins &c. of the kind wherein wire is straightened out, cut, and bent into shape, the bent blank is corrugated by passing it on a pin former through adjustable rolls. The wire 22 in a substantially continuous length is first drawn by rolls 5 and 6 through a straightening device comprising sets of rolls 116, 126, Figs. 1 and 10, at rightangles to one another. The rolls on one side of each set are on a fixed block 117, and those on the other side on a sliding block 118 which is provided with notches 124, 125 which allow it in a certain position to move outwardly on retaining studs 119, 120 to separate its rolls from those on the block 117. Each roll is mounted on an eccentric bearing to enable it to be adjusted also independently. The straightened wire passes up a pipe 7 at the top of which it is severed by a rotating cutter 9, Figs. 1 and 5. At this point it is received and held by lugs 11, 12 and spring- retaining fingers 23 on two rotating disks 13, 14 which are adjustable apart to accommodate wires of different lengths. Between the disks 13, 14 and similarly adjustable, are two disks 17, 18 of slightly greater diameter and rotated more quickly than the disks 13, 14. The wires are by this means rotated about their axes while moving round with the disks, and on passing between two rotating filing rolls 24, 25 have their ends rounded off or smoothed. The wires are next transferred to a travelling chain 92 carrying blocks 94, Fig. 3, from which project pins 26, 39, the pin 26 first engaging the middle of the wire and bending it by drawing it out of the lugs 11, 12 and between inclined plates forming initial bending-means and adjustable spring-pressed fingers 36, Figs. 3 and 8, for the final bending. The wire then passes through corrugating-rolls 41, 42, detents 40 in removable blocks 43 on which co-operate with the pins 39 on the chain blocks 94 to effect the corrugating. The rolls 41, 42 are spring-pressed together and are adjustable apart by inclined blocks 132, 133 slidable under the control of screws 138, 139. The rolls are driven by bevel gear 47, 48, 49, 50 from the shaft 51, the roll shafts being mounted in bearings connected by integral brackets 58 with the bearings for the vertical shaft. At the point of transfer of the wires from the disks 13, 14 to the chain 92 are arranged spring- pressed plates 32, Figs. 3 and 6, held in engagement with grooves in the lugs 11, 12 to retain the wires in position, and a. pair of spring-pressed rock-arms 84 provided at their outer ends with a bevelled face 87 which extends diagonally in the path of the wires and forces them on to the chain.

Novel compounds of the Formula (I) (wherein R is O or α-H(#-OR<SP>5</SP>) in which R<SP>5</SP> is H, tetrahydropyranyl or acyl; and R<SP>1</SP> is α-R<SP>2</SP>(#-COCH 3 ) in which R<SP>2</SP> is H, OH or O acyl, or R<SP>1</SP> is α-R<SP>4</SP>(#-OR<SP>3</SP>) in which R<SP>4</SP> is H or C 1-8  alkyl, alkenyl or alkynyl, and R<SP>3</SP> is H, tetrahydropyranyl or acyl; the acyl groups being derived from hydrocarbon carboxylic acids of up to 12 carbon atoms which are optionally substituted; and there is a #<SP>4</SP> or #<SP>5(10)</SP> double bond present) are prepared by treating steroids of the Formula (II) (wherein Ac is acyl and R<SP>1'</SP> is O or α-R<SP>2'</SP>(#-COCH 3 ) in which R<SP>2'</SP> is H or acyloxy) with an α-fluorinated amine (wherein X<SP>1</SP> is F or Cl; X<SP>2</SP> is F, Cl or CF 3 ; and A and B are each C 1-6  alkyl or N.A.B. is C 5-7  alkyleneimino) at a temperature of 0 C. or below in an inert, non-polar organic solvent to give the required #<SP>5(10)</SP>-3#-acyloxy compounds. A mixture of the 7α- and 7#-fluoro isomers is formed, the latter predominating; they may be separated by conventional means. The 3-arylates on hydrolysis give the 3#-ols and these on oxidation the 3-ones. The #<SP>4</SP>-3- ones are prepared by mild acid isomerization of the #<SP>5(10)</SP>-3-ones or by Oppenauer oxidation of the #<SP>5(10)</SP>-3#-ols. Hydrolysis of the 17α-aryloxy compounds gives the 17α-ols which may in turn be reacylated. The 17α-hydrocarbon -17#-ols are prepared from the 17-ones and hydrocarbon metal derivatives; the 17α- alkynyl compounds may be catalytically hydrogenated to the 17α-alkenyl and 17α-alkyl compounds. The 17#-ols unsubstituted in the 17α- position are prepared by reduction of the 3,17- diones to the 3,17-diols and, when required, back-oxidation with a quinone to the 3-keto- 17#-ols. The 17#-ols may be acylated. Also, the 3-keto compounds of the invention may be backreduced to the 3#-ols, which may be acylated. The tetrahydropyranyl ethers are prepared from the free ols and dihydropyran. The B-homo steroids of the invention have, variously, progestational, anabolic and antiandrogenic properties, and they may be made up into pharmaceutical compositions with suitable carriers.
