Title: Improvements in hydraulic retarders
Inventor: HOBBS ARTHUR FREDERICK
IPC: B61K7/08
Filed: 1958-01-20
Abstract: 859,756. Track brakes. HUMPHREYS & GLASGOW Ltd. Jan. 20, 1959 [Jan. 20, 1958], No. 1922/58. Class 103 (1). An hydraulic retarder for slowing down moving bodies, comprises a main striker engageable by a body and connected to an hydraulic resistor, means whereby the striker is moved against hydraulic pressure, and a resetting striker arranged for engagement by the body when it has cleared the main striker, and so mechanically connected to the main striker that movement of resetting striker resets the main striker and vice versa. A toothed ring 11, carrying the main striker 40, forms, with castings 13, 14, a housing 10 rotatably mounted on a fixed shaft 20 between frame members 42, 43 and having its liquidfilled interior 16 divided into chambers 21, 22 by partitions 17, 18 fixed to castings 13, 14; the shaft 20 has vanes 24, 25 in chambers 21, 22 in close fit with the housing, and four radial bores 27-30 entering a blind axial hole 26 closed by a plug 31 having a tapered end 32 restricting the bores 27-30, the plug being screw-threaded to adjust the restriction. When a body, e.g. a dummy axle of a mine-car, engages striker 40 it rotates housing 10 to force liquid through the bores 27-30 from one side of the vanes to the other, to retard the body. A gear sector 46 pivoted at 45 to the frame members 42, 43, meshes with the teeth 12 of ring 11 so that when housing 10 is rotated the sector 46 is oppositely rotated to raise a resetting striker 48 which on being struck by the body rotates the housing 10 to further retard the body and raise the striker 40 to its operative position. A heading reservoir 35 on housing 10 is connected via passage 36 in casting and bores 37, 26 and 27-30 in shaft 20 to the interior 16. Restricted initial flow of liquid past the vanes 24, 25 may be permitted by shallow recesses in the castings 13, 14 to reduce the impact of the body and strikers. In a modification, Fig. 6, not shown, the header tank is replaced by a filler opening closed by a plug, and four additional radial bores in the shaft are normally closed by a spring-biased tapered plug in a second blind axial hole in the shaft and act as a pressure-relief valve. The resetting striker may be fixed to a housing similar to housing 10 and the strikers may have resilient striking faces, e.g. plungers with blocks of rubber at each end.

Title: Improvements in and relating to positional servo systems
Inventor: MILNE NORMAN

Abstract: 847,693. Servo systems. BRITISH THOMSON-HOUSTON CO. Ltd. Jan. 12, 1959 [Jan. 22, 1958], No. 2233/58. Class 40(1). In a servo system, giving coarse and fine indications of misalignments, in which the outputs from two or more selsyn receivers are added to give a single error signal, false indications of alignment are avoided by ¢-wave rectifying the separate outputs before adding them together. Preferably, as in the Figure, the ripple component of the summation signal is amplified and used to indicate misalignment, thus allowing the use of A.C. rather than D.C. amplifiers.

Title: Improvements in or relating to circuit arrangements for use with electro-magnetic particle accelerators
Inventor: CARRUTHERS ROBERT
IPC: H05H7/04
Filed: 1949-01-31
Abstract: 662,341. Pulse generating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 16, 1950 [Jan. 31, 1949], No. 2676/49. Class 40 (vi). In an electromagnetic particle accelerator in which it is required to relate the timing of an operation to the attainment of a given value of the cyclically-varying magnetic field within the machine, a voltage is produced which varies in correspondence with the field and is applied to trigger a circuit to produce an output pulse at a selected point in the cyclic variation, the output pulse then being used to initiate the required operation. Fig. 2 shows a circuit in which a sinusoidal voltage which varies in correspondence with the magnetic field of the machine is applied to the primary winding of a current transformer T1. The positive excursions of the voltage are limited by resistor R1 and diode V1 and are applied to a multiar trigger circuit of the type described in Specification 583,553. An output pulse is produced at the anode of valve V3 the timing of which can be adjusted by varying the bias voltage applied to the anode of diode V2. The accuracy of timing may be increased by using a germanium or other crystal rectifier for diode V2. In a modification shown in Fig. 3 in which a crystal diode V2 is used the contact A1 of a highspeed relay A/1 disconnects the input voltage from the crystal diode V2 during those parts of the cyclic variations of the input voltage which would give rise to an undesirably high reverse voltage across diode V2.

In the form shown in Fig. 2, the operating-meohanism is of the type comprising a screw-actuated coupling-member 9 provided with driving-teeth 10 to engage an internal shoulder on the wheel hub and with a toothed conical part 12 coacting with a conical abutment 20 on a fixed member 15 to expand brake shoes 13 against the hub. An angularlybent spring 17 is fixed to each shoe 13 and is provided with a projection 18 engaging a peripheral groove 19 in the member 15, the groove permitting a limited axial sliding movement of the shoes, rotary movement of the shoes being prevented by lugs 16 on the member 15 engaging between the edges of adjacent shoes. In the form shown in Fig. 5, U-shaped springs 21 are fixed to the shoes 13 and engage longitudinal slots in the fixed member 15. In another modification, Fig. 7, U-shaped springs 25 are held fast in gaps in the member 15, their limbs engaging longitudinal slots in the shoes 13. In a further form, angularly-bent spring tongues similar to the springs 17, Fig. 2, project from a longitudinally-slit or bent-up sleeve adapted to be sprung into the member 15, their ends being slotted to engage headed studs fixed to the shoes 13. In the retracted position, the resiliently-mounted shoes act as a drag spring on the inner end of the coupling-member 9.

Abstract: 206,759. Marks, E. C. R., (American Flyer Mfg. Co.). Jan. 30, 1923. Railways. - A switching arrangement whereby ordinary house current may be safely used for toy electric railways, comprises a lamp or other resistance 21 for reducing the voltage and an electromagnet 14, 15 connected in shunt to the main circuit 10, 11 to the rails. This main circuit passes through the adjustable armature 16 of the electromagnet by the contacts 28, 29 and is broken when the armature is attracted. When the railway is in use the current through the electromagnet is not sufficient to lift the armature but should the circuit between the rails be opened, all the current will pass through the electromagnet, the armature will be lifted and the rails rendered dead. To re-establish the circuit to the rails, a switch 33 is depressed, short-circuiting the. electromagnet and releasing the armature. The arrangement shown is adapted for either a 32-volt or a 110-volt supply. For the latter an extra resistance 22 is inserted bv a switch 25.
