Abstract: 491,089. Vehicle brake operating mechanism. EVERNDEN, H. I. F., and MITCHELL, A. Feb. 26, 1937, No. 5867. [Class 103 (i)] Operating mechanism for the brakes of an automobile independently sprung wheel that is carried by links, leaf springs or the like extending from the chassis and in which the brake expander moves normally to the plane of the brake drum comprises two levers mounted respectively on the wheel assembly and on the chassis and connected the one to the expander and the other to the pedal &c., the levers being connected by a link of such a length and so positioned that movement of the expander relatively to the brakes due to the up and down movement of the wheels is substantially prevented. In Fig. 1, the member B which carries the stub axle B<1> of a steering wheel is connected to the chassis by a pair of equal and parallel links A, A<1>. A lever E<2> pivoted to the chassis is connected by a link E<5> to the driver's control and by a link E<3> to a lever E<1> mounted on a boss on the member B. The lever E<1> is connected by a link E<4> to the brake expander D. In this case the link E<3> is equal and parallel to the links A, A<1>. One of the pivots of the link E<4> lies in the axis of the steering pivot B<2>. In a modification, the lever E<1> is mounted on the back plate of the brake and the link E<3> adjacent its connection to this lever is broken by a vertical pivot lying in the axis of the steering pivot. In Fig. 5, link H<2> corresponding to the link E<3>, Fig. 1, is connected to a horizontal lever H mounted on the brake back plate C<1> by a pivot H<5> which lies in the axis of the steering pivot, the link being broken by a horizontal pivot H<4>. If the wheel carrying links A are of unequal length and initially parallel, the link connecting the two levers is arranged parallel to the wheel carrying links with its ends lying respectively in the planes containing the inner and outer fulcrums of the wheel carrying links. Where the wheel carrying links are not initially parallel or where leaf springs are employed the length of the link is determined by laying out the geometry of the linkage for the range of wheel movement.

IPC: H02H7/16
Filed: 1953-03-03
Abstract: 727,197. Protective arrangements. GENERAL ELECTRIC CO. March 3, 1953 [March 4, 1952], No. 5882/53. Class 38 (4). [Also in Group XL (a)] A shunt spark-gap device for limiting the voltage across a series stabilizing condenser 12 of a transmission line 1 under fault conditions, comprises electrodes 3, 4, Fig. 1, within a chamber 5 having inlet and outlet openings 7, 6 and to which air under pressure (say from a container 9) is admitted, under the control of a solenoid-operated valve 10, 11, when the spark-gap breaks down, thereby to re-establish periodically the normal break-down voltage of the gap at the beginning of each half-cycle of the current during fault conditions. The air pressure applied to the inlet is maintained in excess of 1.88 times the maximum pressure possible at the outlet so as to ensure a uniform flow of air (at sonic speed) through the inlet under all conditions of the arc. The optimum rate of air supply to the chamber is from 1.5 to 3.5 times 10<SP>-6</SP> cubic metres per second per KVA rating of the device and the volume of the chamber is from 1.58 to 3.16 times 10<SP>-8</SP> cubic metres per KVA rating of the device. A trigger electrode, which may be controlled by a gas-discharge tube, may co-operate with the main electrodes 3, 4 and may be so arranged as to protect the walls of the chamber from the arc. The spark-gap may be of the form shown in Fig. 3, wherein the electrodes 3, 4 are mounted on adjacent ends of coaxial metal tubes 19, 20 carried by insulators 27, 28 which are secured by rings 31, 32 to an annular chamber 35 having conical inner walls 38, 39 which constitute the trigger electrode. The compressed air is supplied to chamber 35 through an inlet 41 and passes to the main electrodes through orifices 43, 44 at the outer edges of the walls 38, 39 thence passing into the tubes 19, 20, which are open to the atmosphere at their outer ends. Arc-limiting electrodes 54, 55 may be mounted within the main electrodes 3, 4. To facilitate transfer of the initial arc from the trigger electrode to the main electrode, the inner edges of the walls 38, 39 may be spaced by an insulating ring 53, which may have radial passages through which the compressed air passes.

Abstract: 539,259. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd. (Mergenthaler Setzmaschinen-Fabrik Ges.). March 18, 1940, No. 5896/41. Divided out of 539,076. [Class 100 (iii)] Assembling and clamping matrices; ejecting type-bars. Common adjusting-means for matrixline length are provided for the assembler-slide, the' vice-jaws, and the ejector. A slidable rod 5, Fig. 1, carries a stop 8, which is engaged by an abutment 9 on the assembler-slide 1 to limit the length of the assembled line, the abutment 9 engaging the stop through an adjustable screw 10. A pivoted detent 12 on the stop 8 can be rocked down to allow a small additional movement of the assembler-slide, as heretofore, to permit of the insertion of a last matrix. The rod 5 is in two parts, which are connected by a releasable coupling 7, and the left-hand section of the rod is connected tc, and serves to adjust, the left-hand vice-jaw 4. The releasable coupling permits the separation of the two parts of the rod 5 when the vice-frame is tilted downwards. The common adjustment of the stop 8 for the assembler-slide and of the vice-jaw is effected by a rotatable knob 35, the. shaft of which carries a pinion dn engagement with a rack 39, which is secured to the rod 5. The shaft of the knob 35 also carries a stepped cam, upon which rests a lever 41 connected by a rod 42 to the ejector adjusting- lever. The knob 35 is movable axially, and raises the lever 41 from the stepped cam when it is pulled forwards. After adjustment of the cam, the knob is pushed rearwards, and the lever 41 falls back on to the cam. The rod 42 is connected to the ejector adjusting-lever through a releasable coupling, so that the ejector can be adjusted independently of the assembler-slide and the vice-jaws. On the rise of the assembler. after composition is completed, a pin 14, Fig. 8, carried thereby rocks a lever 15, which operates a releasing-pawl 16, so that the long finger of the line-delivery carr'.age is released and is moved by a spring into contact with the end of the composed line. After delivery of the line, the carriage and the long finger are returned to the right by a lever and a cam. The usual line-stop on the first elevator, which is pushed back by the entering line, is returned to initial position by a pusher connected to the matrixtransfer slide.

Title: Apparatus for deodorising and cooling and, if desired, pasteurising lacteal liquids under vacuum
IPC: A01J11/04
Filed: 1939-02-22
Abstract: 525,488. Pasteurizing, deodorizing and cooling milk. MURRAY DEODORISERS, Ltd. Feb. 22, 1939, No. 5898. Convention date, Feb. 22, 1938. [Class 49] Apparatus for deodorozing and cooling lactial liquids is provided with a single condenser capable of supplying different degrees of vacuum to the deodorizer and to the cooler. The apparatus comprises a pasteurizer 1, a deodorizer 2 and a cooler unit 3 arranged around an ejector condenser 4 which is of the cone type constructed to permit a different degree of vacuum to be obtained therefrom for the deodorizer from that obtained for the cooler by isolating a number of the upper cones 5 by surrounding them with an insulated wall 6 so as to provide two chambers 8, 9, in the condenser ; the isolated cones cause the creation. of a high degree of vacuum and the further cones a lesser degree. The vacuum as applied to the pasteurizer by way of a pipe 22 from the deodorizer is automatically controlled by valve mechanism 24, Fig. 7, so that the vacuum applied to the pasteurizer is of less degree than that of the deodorizer. The valve mechanism comprises a bomb-type valve 27 on a seating 28 and subject there to the action of the vacuum applied within the deodorizer. The. valve is connected to one end of a lever 31 which is threaded at its opposite end to take an adjustment nut 35 connected by a wire 38 to a piston 39 within a cylinder 40. This cylinder is connected to the condenser in such a position that above the piston 39 the cylinder is subjected to the vacuum within the main chamber 9 of the condenser, that is, to the same degree of vacuum as in the deodorizer. The connection between the deodorizer and the cooler has means in the form of a float-operated valve 42 Fig. 4, at the bottom of the deodorizer which, while enabling passage of liquid from the deodorizer to the cooler, prevents equalizing or balancing of the different degrees of vacuum in the deodorizer and in the cooler. Specifications 413,460 and 418,591 are referred to.
