Title: Improvements in and relating to gear changing means
IPC: F16H41/04
Filed: 1939-07-18
Abstract: 539,478. Variable-speed gearing. PORSCHE, F. July 18. 1939, No. 20823. Convention date, July 22, 1938. [Class 80 (ii)] In a method of changing gear, particularly for automobiles, wherein change to higher or lower gear is effected by the torque of the guide-wheel of a torque-convertor as a result of drop or increase, respectively, in the turbine-wheel torque, the supporting torque opposing the guide-wheel is dependent on and increases with the speed of the pump-wheel. In the arrangement shown in Figs. 1 and 2, the engine 1 drives change-speed gear 6 through a torque-convertor consisting of a pump-wheel 3, turbine 4, and a guide-wheel 5 having an arm 7 arranged between spring-urged pistons 23, 24 which communicate through pipes 9 and a throttle 12 with a gear-pump 10 coupled to the pump-wheel 3. The supporting torque opposing the guide-wheel is determined partly by the speed of the pump-wheel and partly, on account of the springs 27, 28 in connection with the pistons, by the displacement of the guidewheel. The arm 7 operates, through links 31, 34 and a lever 33, ratchet-mechanism 35 provided with a resiliently coupled arm 36 for closing contacts 37 which are connected to the gear 6. The arm 36 has a notched sector 38 co-operating with a detent 39 which is connected by a cable 19 and linkage 16, 15 to a throttle-valve 14. On starting in first gear, the guide-wheel torque decreases until the convertor reaches its highest efficiency, that is with a 1-1 transmission ratio. The guide-wheel torque then reverses and increases, the arm 7 moves to the left in opposition to the piston 23, and the arm 36 engages the contact 37 corresponding to the second gear. The guide-wheel torque again reverses, but the arm 7 is unable to overcome the piston 24. When. however, a hill is climbed, the guide-wheel torque increases, and at a pre-determined speed, the arm 7 moves to the right in opposition to the piston 24, and the arm 36 is moved back to the first-gear contact. During movement of the arm 36, the detent 39 closes the throttle 14 to interrupt power transmission and thereby facilitate gear-change. A hand-lever 40 for operating the ratchet mechanism 35 and contact-arm 36 independently of the arm 7, to permit of employing the engine as a brake, is mounted on a pivot 41 and carries the pivot 32 of the lever 33. The hand-lever is normally locked by a catch 42. The arm 7 may be arranged to operate a changespeed gear mechanically and directly. The piston-arrangement for opposing the guide-wheel may consist of a single piston, or may be replaced by a centrifugal governor, or by an electromagnet in circuit with a generator couples to the pump-wheel.

Title: Improvements relating to processes for the manufacture of industrial carbon bodies from pit coal
IPC: C04B35/532
Filed: 1952-08-21
Abstract: In a process for the manufacture of industrial carbon bodies from pit coal by coking, finely comminuted pit coal is mixed with a liquid or solid synthetic resin produced by a condensation reaction, such as a phenol resin, a shaped article is produced from the mixture by pressing and the shaped article is subjected, after complete hardening of the synthetic resin, to a heat treatment in which the pit coal and the synthetic resin are coked. The synthetic resin may be in the form of a solution or a powder and the pressing may take place in the cold or in the hot state. Hardening is effected by thermal treatment with or without the application of pressure, or by means of acid treatment.  In a modification the starting mixture has the addition of an inorganic or organic acid or an acid salt as a hardener.  Plasticizers and wetting agents may be added to the starting mixture and inorganic substances such as metals, metallic oxides or silicates, carbides, kaolin or glass may be added.  The pit coal may be subjected to a pre-treatment such as a chemical treatment to reduce the ash content or a thermal treatment.  The comminuted pit coal may be mixed with graphite, coke or anthracite.

Automatic exchange systems.-In a telephone system in which a call is set up by a subscriber over a train of automatic switches, the release of all the switches is always controlled by the calling subscriber, but if the called subscriber hangs up first, the test relay of the connector is operated to cause the release of the called line. Final selector. The tens impulses step up the wipers of the final selector, relay C being energized. The final digit operates the rotary magnet R, and relay E in parallel, and steps the wipers to the called line. The relay E prevents full operation of the test relay G when passing over busy lines. Called line busy. Relay G operates its flysprings 6, 5 until relay E releases, when it fully operates from earth at B (9, 8), and connects busy tone at G (11, 12) to the positive lead. When the subcriber hangs up, relays A, B. G release in turn, and the release magnet Z is operated to return the switch to normal. Called line free, ringing and completion of connection. When relay E releases, relay winding H (1, 2) operates fly-springs 5, 6, and then locks over winding H (3, 4). Relay E operates and completes a circuit for winding G (3, 4), which operates fly-springs G (5, 6).

If the calling party hangs up first, relays A, B; F, G, H; and D, E release in turn, the switch is restored by magnet Z, and the preceding switches released by removing ground at F (8, 9). If the called party hangs up first, relay D releases and de-energizes relay E at D (7, 8) so that relay G fully operates, removing earth from relay H and the called subscriber's cut-off relay, and releasing his line. An alarm device is operated from earth at F (14, 15) if the calling subscriber does not hang up in a specified time. When the calling party hangs up the train of switches fully releases.

Title: Procedure and device for the exclusion of errors due to mounting in measurement in single-or multi-phase balancing of rotors in balancing equipment
IPC: G01M1/04
Filed: 1958-07-04
Abstract: 889,877. Measuring rotor unbalance electrically. SCHENCK MASCHINENFABRIK G.m.b.H., CARL. July 4, 1958 [July 5, 1957], No. 21414/58. Class 40(1). In a rotor unbalance measuring machine means are provided for removing errors due to asymmetrical mounting of the test body on the machine. As shown (Fig. 2), a rotor 1a is mounted on the carrier 2a of a balancing machine rigidly supporting the stator of a transducer 21 whose moving coil is attached to a feeler resting on the inside bore of the rotor, and also supporting the stator of a second transducer 22 whose moving coil senses the axial displacements of the rotor. Thus the signal from transducer 21 is proportional to the radial mounting error, and that from transducer 22 is proportional to the axial mounting error of the rotor on the balancing machine. The total unbalance of the assembly is sensed in two planes by transducers 23, 24, and the correct proportions of the transducer signals are combined at 25, 26, 27 to indicate on meters 28, 29 the unbalance of the rotor about its correct axis of rotation. In another embodiment (Fig. 3) transducers 33, 34 sense the errors due to incorrectly mounting the shaft 30a of rotor 30 in the balancing machine.

Abstract: 379,065. Ball bearings ; lubricating. HAMMOND CLOCK CO., 2911, North Western Avenue, Chicago, U.S.A. July 28, 1931, No. 21490. Convention date, July 30, 1930. [Classes 12 (i) and 12 (ii).] The stator of a synchronous motor of the unwound armature type for gramophones and the like is so mounted as to be capable of a slight rotary motion against the action of a spring, the rotation of the stator being also checked by friction ; the moment of inertia of the rotor is preferably considerably greater than that of the stator. In the arrangement shown the stator 11 is arranged inside the rotor 10 and is mounted on a sleeve 15 arranged within an outer bearing 16. The sleeve 15 carries an arm 19 which can oscillate between stops 17, 18 under its action of springs 22. The sleeve 15 is closed at its lower end by a plug 60 resting on perforated metal washers 56, 58. The disc 60 carries a blade spring 62 on which rests a ball 66 forming a thrust bearing for the gramophone spindle 64. The lower part of the motor housing 32 is enclosed by a partition 44 to form an oil reservoir. The partition 44 is formed with a vent plug 52 so arranged as tc prevent the escape of oil if the motor is inverted.
