IPC: F16C7/04
Filed: 1918-08-09
Abstract: 118,411. Schultz, E. J. A. May 10, 1917, [Convention date]. Connecting-rods.-In order to reduce the clearance at the ends of the exhaust stroke of an internal-combustion engine, the connecting-rod is made in two parts sliding one wthin the other. One part d is formed with packing grooves j and works as a piston in a cylindrical chamber i formed in the other part a. Relative movement of the parts is limited by a bolt f, carried by the part a, and passing through a slot in the part d. The parts are pressed apart by a spring h, and their inward movement is cushioned by the compression of the a.ir in the space i. A port k may be formed in the walls of the chamber i in order to restore air lost by leakage. In the case of a rotary engine, the piston d is sealed by oil collecting in the chamber i.

Title: Improvements relating to apparatus for transferring liquid from one location to another
IPC: H01M6/38
Filed: 1959-04-16
Abstract: 917,061. Batteries. YARDNEY INTERNATIONAL CORPORATION. April 16, 1959 [April 16, 1958], No. 13026/59. Class 53. [Also in Groups XXVIII and XXIX] Apparatus for filling a battery with liquid comprises a reservoir 30 having an outlet pipe 21 leading to the battery from a chamber 50 on the end of the reservoir. The chamber 50 is closed by a diaphragm 203 which can be punctured by a member 201 when the pressure of the liquid in the reservoir is increased to force the diaphragm outwardly into the position shown in dotted lines in Fig. 2. To prevent a sudden shock setting up waves in the reservoir of sufficient intensity to cause movement and puncturing of the diaphragm, a shield 205 is situated over the diaphragm and fixed at a few points to the end wall of the reservoir leaving narrow passages between the rim of the shield and said end wall. These narrow passages circuitous path for the liquid flowing from the reservoir to the chamber 50, the convex portion 302 of the shield serving to deflect any shockwave propagated in the reservoir towards the diaphragm 203. Fig. 4 shows a modification in which the shield comprises two or more plates 401<SP>1</SP>, 401<SP>11</SP> having staggered perforations. Bellows 410<SP>1</SP> may also be provided to absorb shock-waves. The increased pressure in the reservoir 30 required to puncture the diaphragm 203 may be produced by the expansion of an inflatable bladder 31, Fig. 1, which is connected by a pipe to an enclosure 40 containing a trigger mechanism which when operated allows compressed gas to flow from a container 60 into the bladder 31. The trigger mechanism comprises a fusible link 45 which retains a slidable weight 42 in position against the pressure of a spring 44. The link 45 may be ruptured by an electric current and the weight 42 is then projected against and breaks the closed end of the tube 51.

Abstract: 1304931 AC power supply to vehicles A MOEN 18 March 1970 [26 March 1969] 13092/70 Heading B7L A system for A.C. power supply to a vehicle powered by motor M and movable along a track, e.g. an electric crane, has contact rails 1-3, each carrying a different supply phase and extending along the track, that are adapted to co-operate with collectors 16-18 on the vehicle, each rail 1-3 having additional conductors 4-9 each of the same resistance per unit length as the rails 1-3 and extending adjacent the contact rails but insulated therefrom, the number of additional conductors adjacent each contact rail being equal to the number of other contact rails and each additional conductor being conductively connected to a respective one of the other contact rails at locations along the track, preferably at contact rail joints, by transverse connections 10-12. Thus each group of additional conductors and rail (1, 4, 5), (2, 6, 7), (3, 8, 9) comprises each of the phases of the supply. The currents of each phase are distributed equally among the conductors of that phase to produce effectively three 3-phase sub-systems, the phases of each sub-system being closely spaced and thus being of small reactance.

[Class 98 (i)] In a change-box for photographic flat films having no changing tabs, the films are held in position by spring members adapted to be automatically released when a film is changed. As shown, the box comprises an outer casing d and an inner casing e containing the film pack h and a light-shutter f and carrying springs n fixed at their upper ends to the casing e and having their free ends p extending below the casing. The springs n slide in guides o so that when the box is opened as shown in Fig. 2 to change a film, the springs exert no pressure on the film pack h but on closing the box again the springs are bent by pressure of the ends p on the bottom of casing d to assume a wave form, Fig. 4, and exert pressure on the pack. The film is changed by a spring k which, on withdrawal of the casing e after exposure, engages the bent end c of the paper backing b of the exposed film a and retains the film in the casing d, the film being pressed to the back of casing d by the springs k and l and occupying a position in the space i, Fig. 4, behind a stiff movable partition w when the box is again closed.

Abstract: 383,894. Fluid-pressure brakes. HILDEBRAND, W., 3, Ulmenplatz, Lichterfelde, Berlin. May 14, 1932, No. 13938. [Class 103 (i).] A compressed air brake comprises a main and an auxiliary brake cylinder, both controlled by a main control valve, and an auxiliary control valve S arranged between the auxiliary brake cylinder C<2> and the main control valve the piston k of which is subjected to or freed from air pressure by the action of a valve V operated by an electromagnet E dependent on a dynamo D, the action of which varies accord. ing to the speed of the vehicle. Pressure air from the train pipe L passes through a valve a and a pipe r to hold the piston K in the position shown in which the cylinder C<2> is connected to the pipe l from the main control valve. As the vehicle slows the electrical energy from the dynamo D is diminished and allows the armature of the magnet E to fall, close the valve a and open the valve b. The piston K is thus connected to atmospheric opening O<1> and moves to the right connecting the cylinder C<2> to atmospheric opening O<2>.
