Title: Improvements in life-guards for vehicles
IPC: B60R21/34
Filed: 1935-02-22
Abstract: 451,050. Vehicle lifeguards. ATKINS, W. J., 71, Briarwood Road, Stoneleigh, Ewell, Surrey. Feb. 22, 1935, No. 5805. [Class 103 (ii)] A guard for the front wheel of a vehicle comprises a frame 4 mounted on the stub axle or king-pin so as to be movable with the wheel 2, a lower front member 9 of the frame carrying a pivoted guard 10 and a forwardly-projecting operating member 11 adapted on contact with an obstruction to release the guard 10 from its normal horizontal position so that it falls into an operative inclined position. As shown, a second guard 13 which is pivoted to a longitudinal member 14 of the frame extends along the inner side of the wheel and operates similarly to the guard 10. A spring-pressed locking-bar 17 slidably carried by the member 14 normally holds the guards 10, 13 horizontally by means of a latch 21 on the bar engaging a lug 22 on the forward end of the side guard and a pivoted latch 31, connected by a link 30 with the rear end of the bar, engaging a lug 32 on the rear end of the side guard, a lug 23 on the front guard 10 being latched beneath the lug 22. The bar 17 is coupled by a link 18 and lug 19 to the operating member 11 which when struck pushes the bar rearwardly and releases the lugs 22, 23, 32 to lower both guards. The guards may also be released by means of a supplementary control such as a Bowden cable manually operable by the driver and connected to the bar 17. Instead of being fixed for movement with the guard 10 the lug 23 may, as shown in Fig. 2, be carried by a collar 24 having a spring-pressed dogclutch engagement 25 with the guard 10, thus providing for operation of the guard 10 by an obstruction insufficiently high to contact with the member 11. The guards 10, 13 and operating member 11 comprise tubular frames having a series of projections 33 to which expanded metal or network grills 34 are detachably secured. Ground-engaging rollers 36 or skids may be provided on the guards or the downward movement of the guards may be limited by stops. A similar additional device may be applied to the rear wheels, the side guard 13 being omitted. According to the Provisional Specification, the member 11 and guards 10, 13 are held in the inoperative position by a verticallydisposed, spring-controlled, pivoted catch.

Abstract: 448,904. Photometric apparatus. HOLOPHANE, Ltd., and ENGLISH, S., Holophane House, Elverton Street, Vincent Square, London, andEVERETT, EDGCUMBE, & CO., Ltd., and EDGCUMBE, K., Colindale Works, The Hyde, Hendon, London. Feb. 27, 1935, No. 6270. [Class 97 (i)] A photo-electric photometer for measuring the intensities of illuminants of different colours, such as an incandescent electric lamp and a vapour discharge lamp, is provided with a manually operable resistance control for applying colour correction factors to the galvanometer readings in order to compensate for the difference between the colour sensitivity curve of the photo-electric cell and that of the eye, so that the galvanometer reads directly in light intensity units or known multiples thereof when the control is set to the appropriate position for the colour of the light to be measured. The apparatus shown consists of two similar photo-electric cells M, N connected to a galvanometer G which is provided with shunt resistances R1, R2 connected to studs C, D over which a contact arm T is adapted to move. When the arm is in contact with stud C, the galvanometer is shunted by the resistance R2, and when on the stud D, the shunt resistance is R1+R2. When the' arm T is on a further stud E, no shunt is applied to the galvanometer. Further studs A, B are provided, the stud A enabling the galvanometer to be short-circuited for transport and'the stud B providing an " off position for the arm T. A second arm T1 rotates with the arm T over studs A1 ... E1, and is adapted. to insert resistances R3, R4 in series with the galvanometer, these resistances being of such magnitude as to maintain constant the total resistance of the galvanometer circuit between the points Q, R. There is also provided an arm V movable over studs F, H, K, L to vary the scale of the readings. In position F the cells M, N are connected in parallel to the points Q, R and the galvanometer reading divided by ten represents foot-candles. In position H only the cell N is connected to the points Q, R and the galvanometer circuit is shunted by a resistance R5 of such magnitude. that the galvanometer reads foot-candles directly. The shunt resistances R6, R7 connected to the studs K, L provide for further modifications in the scale of the galvanometer readings.

Title: Improvements in or relating to electrolytic machining
Inventor: SADLER BRIAN
IPC: B23H3/00
Filed: 1965-02-12
Abstract: In electrolytically machining a workpiece by supplying an electrolyte under pressure to a space between two electrodes, one of which is formed at least in part by the workpiece, the pressure of the electrolyte is used to actuate means for clamping in a predetermined position one electrode or a member adapted to be rigidly held to it. As shown, the workpiece 10 mounted on a turntable 12 has a number of hollow radial spokes the inner and outer surfaces 11a, 11b of the ends of which are to be tapered. The tool electrode 14 comprises a metal body 15 supporting a cathode assembly 16 having a shaped insert 17 and a plug 20 having an appropriately shaped surface and channels 23.  The spoke of the workpiece to be machined is brought opposite the tool and the turntable locked in position, a beeswax plug 47 is inserted in the spoke and the tool brought up to it.  Electrolyte is then supplied under pressure from reservoir 43 by pump 42 through conduit 41 and annular chamber 21 to the work gaps 18, 19 and via conduit 40 to a movable cylinder 35 on a fixed piston 34, the cylinder thus moving downwardly and moving a clamping member 27 to clamp the workpiece and make electrical contact between an annular contact 28 carrying input terminals 30 and an annular copper contact 26 secured to the turntable shaft 13 and engaging the workpiece. The electrolyte escapes through gap 18 and via channels 23 into a tank 44 from which it is returned. to the reservoir.  When valves 50, 51 are operated to cause electrolyte to flow instead along by-pass conduit 48 the clamping action on the workpiece is released and also the electrical supply to terminals 30 is interrupted.  Alternatively to releasably clamping the workpiece, the machining electrode may be movably mounted and clamped by the electrolyte pressure. <PICT:1025817/C6-C7/1>

[Classes 83 (ii) and 83 (iii)] Transferring blanks.-A method of assembling a stack of plates in a housing comprises assembling the plates in stack form in one end of a hollow body, compressing them with a spring in the hollow body opposite a recess and an opening therein to a length determined by an opening of the housing and then moving the plates and compressed spring laterally from the hollow body into the housing by pressure from a member in said recess. A block 1, which may comprise two parts 2 and 3 bolted together, has a vertical bore 5 and a horizontal slot or recess 8 containing a sliding piece 24 movable forwardly by a rod 27 but normally kept at the rear of the recess by a spring 28. A vertical slot 6 along a side face of the block joins the bore 5 tangentially.
