Title: Method of and means for automatically releasing driving power when a predetermined maximum load is reached
IPC: F16D9/04
Filed: 1922-12-27
Abstract: 216,168. Jones, S. Dec. 27, 1922. Breaking-pieces for relieving strain are made of hard drawn steel wire, such as piano wire, the elastic limit of which approximately coincides with its ultimate breaking strength. As applied to coal-crushing machine used in gas manufacture, a toothed driving-wheel 2, having arcuate pieces 10 clamped to its spokes 18, is freely mounted on the shaft 1 driving the rolls (not shown). Pins 5 are carried by the members 10 and by arms 3 obliquely radiating from a boss 4 secured to the shaft. Bobbins 6, 7 are mounted with rotational freedom on reduced parts of these pins and are separated by wooden distance pieces 8. One or more turns of unannealed drawn steel wire 15 are wound around the members 6, 7, 8, the ends being fastened to screws 16. Wedges 17 may be driven under the wire to tauten it. When fracture occurs, the parts .8, 17 drop away and, the bobbins 7 being at a greater radius than the bobbins 6, the wheel 2 rotates freely. The centre lines of the arm 3 and distance pieces 8 form right angles. The size and number of turns of wire may be varied in accordance with the desired load limit. The Provisional Specification describes the device as applied to a shaft coupling.

Title: Automatic control circuit for an electrically powered hydraulic pump
IPC: F04B49/06
Filed: 1975-08-26
Abstract: 1465663 Power steering systems CATERPILLAR TRACTOR CO 26 Aug 1975 [17 Jan 1975] 35222/75 Heading B7H A power steering system for a vehicle including a main hydraulic pump 11 driven by the vehicle engine is characterized by an electrical control circuit for automatically actuating an electric motor 40 driving an auxiliary hydraulic pump 31 if the vehicle engine or main hydraulic pump should fail. The electrical control circuit cannot be operated until after the vehicle engine has been started and the oil pressure has reached a sufficient level to close switch 52 and actuate hold-on relay 54. The latter primes relay 46 ready to operate should the fluid flow in the hydraulic system drop and cause switch 51 to close. Closure of contact 45 of relay 46 operates relay 42 to energize electric motor 40. Hold-on relay 54 is de-energized by operation of manual switch 47. The electric motor may be operated to bring the auxiliary hydraulic supply into operation without attempting to start the vehicle engine by actuation of a manual switch 57. A panic shut-down switch 48 is provided.

Title: Improvements in or relating to the production of compressed air in mines
IPC: E21F17/10
Filed: 1953-12-21
Abstract: 736,667. Ventilating mines. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES. Dec. 21, 1953 [Dec. 27, 1952], No. 35459/53. Class 137. [Also in Group XIII] In an arrangement for ventilating deep mines, e.g. an underground working, as shown, fresh air flows down a winding, and air intake, shaft 1 to underground workings in a main road 3, which is separated from the shaft 1 by brattices 4 having openings therein for the passage of hauling material, the fresh air also passing into a by-road 5 accommodating plant 6 for expanding and compressing the air. The plant 6 comprises a turbine which expands the major part of the air entering the by-road 5, the pressure of the air being reduced from about 1.1 atmospheres at the input side of the turbine to a pressure of approximately 0.9 atmosphere at the output side. The expanded cool air passes from the turbine to the underground workings by way of a road 8 and flows off to an uptake shaft 2 from which it is drawn by means of a fan 7 driven electrically, or by means of a steam turbine. An air compressor of the piston, or flow, type, driven by the expansion turbine, compresses the air which by-passes the turbine to a pressure of approximately 6 atmospheres, and supplies it direct, or to the pneumatic network, for operating the various machines in the mine, not shown. In the case where a number of workings have to be supplied with compressed and expanded air a number of turbines with an equal number of compressors are arranged in parallel. It may be an advantage to drive pumps for the cooling water supply, drain means, &c., by a special expansion turbine. Where the power produced by the turbine exceeds the compressed air requirements of the machines at one point, or where the compressed air requirements fluctuate, the loads between the various operating points can be balanced by means of a comparatively narrow pipe. It is also possible to provide underground evaporating refrigerating machines driven directly by the turbines.

Abstract: 788,577. Motor vehicles. DAIMLERBENZ AKT.-GES. Dec. 9, 1955 [Dec. 9, 1954], No. 35463/55. Classes 79(2) and 79(5) [Also in Groups XXXII and XXXIV] In a wheel suspension for a motor vehicle the wheel is guided exclusively by two superposed links of which one, serving also as a driving and/or braking shaft. is arranged approximately on the axis of rotation of the wheel, while the other serving to take up thrust forces acting on the wheel, is arranged under the first mentioned link. As shown, a stub-axle 33 of a non-driven steerable wheel 10 is carried on the upper part 14 of a carrier 15 the lower forked ends 16 and 17 of which are connected to a joint 19 by means of a steering pivot 18. The joint 19 includes a pivot 20 for hollow guide link 21 the inner-forked end of which is pivotally connected to lateral arms 24 of an axle carrier 25 which is rigidly or yieldably connected to the vehicle structure. The stub-axle 33 is connected through universal joints 37 and 40 and a shaft 39 with a brake drum 28, the hub 27 of which is rotatably mounted on the axle carrier 25 which also carries brake shoes 29. The brake drum is provided with cooling vanes 30 supplying air to cooling ducts 31 for the shoes 29, the air being exhausted through radial ducts 32. The wheel may be sprung by torsion springs arranged in the joint 23 or by coil springs on one or both sides of shaft 39 and abutting the link 21 and a suitable bearing bracket on the carrier 25 or on the frame or body of the vehicle.

Abstract: 852,021. Glass manufacture. BRITISH HEAT RESISTING GLASS CO. Ltd. Dec. 10, 1956 [Dec. 10, 1955], No. 35535/55. Class 56. In apparatus for the drawing, and more particularly the upward drawing, of glass rods, tubes or the like from a molten supply, e.g., as described in Specification 675,700, the rollers, which are yieldingly pressed against the rising rod, are so mounted that an increase in the mutual separation of the rollers produces a decrease in the leverage with which the springs act upon the rollers, so that the increased stress in the springs is counterbalanced by the decreased leverage and a substantially constant roller pressure results. The roller drawing apparatus shown is positioned about 30 feet above the drawing apparatus described in Specification 675,700, and consists of two opposed rollers 12 which are tiltable as described in Specification 852,022 to eliminate the twist put into the rod by the rotatory molten supply of Specification 675,700. The rollers 12 are driven through an infinitely variable gear box 27, chain 29 and cordon shaft 26, and are each journalled in arms 13 welded on sleeves 14 journalled on fixed axles 15. Crank arms 32 also are welded to the sleeves 14 and each carry a slide block 42 adjusted relatively to the crank by a screw 40 which is rotated through gearing, universal couplings and shafting by a handwheel 66, so that the pivot 54 of a link 44 which is carried by the block 42 may be set at a required radial distance from the axle 15. Each link 44 is connected to one end of a coil spring 30 the other ends of the springs being secured to cables 50, 52 which are trained around pulleys 48, 50, 51, the pulleys 50, 51 being on a block which is adjustable by a screwed rod 55 whereby the tensions of the springs 30 are adjusted. The arrangement of cables in such that the tensions in the springs are equalized. The springs 30 pull upon the arms 13 in a line which is at an angle not substantially greater than 90 degrees to the line joining the axes 15, 54, so that as the rollers 12 become more separated the angles of pull of the springs 30 on the arms 13 become more acute and the leverage is correspondingly reduced. The rollers 12 are separated, to permit the operative to insert the end of the glass rod between the rollers, by a pedal 67 which swings the linkage 81, 82 under the control of a dashpot 86.
