Title: Improvements relating to trackless conveyors
Inventor: BOOTH RICHARD HERBERT
IPC: G05D1/02
Filed: 1957-11-21
Abstract: 905,551. Automatic steering-control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 21, 1958 [Nov. 21, 1957], No. 36297/57. Class 38 (4). [Also in Group XL (c)] In a system in which means responsive to the magnetic field of a conductor carrying current controls the steering of a vehicle to cause it to follow the course of the conductor automatically, the current is modulated to control the vehicle otherwise than by steering. In Fig. 1, coils 2 and 3 are mounted on a moving vehicle (not shown), so that when they are not symmetrical relative to a cable 1, carrying R.F. current and lying on or beneath the ground, a difference signal derived from a unit 9 operates a steering motor 10 in the appropriate direction to restore the vehicle to a symmetrical position relative to the cable during its travel. Coils 2 and 3 are mounted on an arm which swings with the front wheels of the vehicle to increase sensitivity. Should the vehicle wander off course sufficiently, the sum of the signals from coils 2 and 3 derived from a unit 11 is unsufficient to maintain operation of a relay RL1 so that the vehicle is stopped by disconnecting its driving motor 14 from battery 13. A brake (not shown), may also be applied simultaneously. Where a number of vehicles is involved, each may respond to a different frequency so that different routes are followed. Sections of the cable common to more than one route are energized at several frequencies by setting up plug-boards associated with each frequency. The supplies may be pulse modulated to operate relays or selector switches on the vehicles to remotely stop, load or unload them.

Title: Improvements in and relating to electric phase shifting circuits
IPC: H02M1/04
Filed: 1938-12-14
Abstract: 524,925. A.C. phase changing. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 14, 1938, No. 36465. Convention date, Dec. 14, 1937. [Class 38 (ii)] A phase shifting circuit comprises a centretapped supply winding 20, Fig. 1, across which, in series with a variable resistance 30, a condenser 24 or an inductance 25 may be selectively connected by means of a switch 27 to provide two ranges of phase shift. When used for supplying control potentials to a converting arrangement in which a grid transformer having a saturated core to produce peaking potentials is employed, adjustment of the resistance from a maximum to zero, with the condenser connected, produces a phase displacement from 180-90 degrees logging, and with the inductance connected, adjustment of the resistance in the reverse direction produces a phase shift from 90 degrees logging to zero. In a modification of this to permit adjustment of phase over the whole range to be effected by movement of the resistance slides in one direction a centre tapped resistance 47, Fig. 4, is employed having the two halves connected in parallel, and the change over switch 56 for the inductance and condenser is provided with a trip which is operated by an extension 52 of the resistance arm 51 when it passes the centre tapping 50.

Title: Data storage device
IPC: H01C8/02
Filed: 1954-12-21
Abstract: 758,508. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1954 [Dec. 24, 1953], No. 36898/54. Class 106 (1). A data storage device utilizes the physical phenomenon that if two electrodes are placed in a mixture of finely divided metallic particles and a non-conducting fluid, and if a high potential is momentarily applied across the two electrodes, then the metallic particles are drawn towards the electrodes and form a conductive path between them which path remains, even when the potential is removed, until the mixture is agitated to redisperse the metallic particles. In the particular embodiment described a number of metal containers hold the mixture (tricresyl phosphate and iron filings) each one 17, Figs. 1 and 2, being supported on a bridge plate 19 insulated from a base plate, and each one having associated with it a set of 10 electrodes 42 which extend into the mixture and which are supported on a frame 39 pivoted at either end by links 35, 36 to a second frame 28 slidably mounted on pins 26 to be able to move in a direction parallel to the base plate. A spring 47 tends to move the upper frame 39 to the right, Fig. 2, but this is prevented by a member 49a, and a spring 44 tends to keep the lower frame 28 in contact with a fixed abutment 46. In operation data is entered by first energizing a solenoid to lift the member 49a, thus releasing the upper frame and allowing it to move to the right and downwards, bringing each electrode to a distance of 0.025 inch from the base of its associated container, and data is entered into a particular container by applying a high-potential pulse (300 V.) between the container and a selected electrode thus forming a conductive path between the selected electrode and the base of the particular container. A 10- key keyboard controlled circuit is described for entering data successively into each container. Data stored in a particular container is read out by applying a voltage to the particular container and observing to which of the associated 10 electrodes the voltage is transmitted. An electrical read-out circuit suitable for controlling a record-card punch is described. The store is cleared by momentarily energizing a solenoid 60 which causes the lower frame 28 to be pulled to the left, Fig. 2, and by de-energizing the first mentioned solenoid so that as the lower frame moves to the left, back to its original position under control of the spring 44, the link 35 engages the member 49a and raises the electrodes returning them to their original positions, thus the device is reset and each container of fluid is agitated.

Title: Improvements in radio direction finders
IPC: G01S3/08
Filed: 1929-12-03
Abstract: 344,783. Directive wireless signalling. BARFIELD, R. H., Radio Research Station, Slough. Dec. 3, 1929, No. 36980. [Class 40 (v).] Relates to directive aerials of the t y p e described in Specification 130,490, [Class 40 (v), Wireless signalling &c.], in which the effect of the horizontal component of the received wave is minimized and consists in the provision of means for eliminating residual errors due to the proximity of the earth. As shown in Fig. 1, the aerials in 1, 2 are crossed and earthed through condensers 7, 8, which are respectively designed or adjusted to equalize the impedances of the upper and lower portion of the aerial system with respect to any electromotive process induced in the horizontal limbs 9, 10. For instance the impedance of the upper circuit comprising the aerial 1, the goniometer field coil 13 and aerial 2 is made equal to the impedance of the lower circuit comprising the earth 4, condenser 8, coil 13, condenser 7 and earth 3. In the arrangement shown in Fig. 3, errors due to the proximity of the earth, when long horizontal conductors are used to couple the aerials, are avoided by dividing the coupling-leads into a number of closed-circuit sections 17, 18, 19 transformer-coupled, and preferably enclosed in metallic screens, with electrostatic screens inserted between the coupling-windings.

Abstract: A mechanism for leno-weaving side or centre selvedges has means to raise a standard thread out of co-operation with a leno thread so that more than one weft thread is wovenin by the leno thread before the crossing of the leno thread over standard thread.  In Figs. 6 and 7 (not shown) the standard threads are passed through stationary healds 11 and the leno threads through a reciprocating slide 7\sv that has slanting hooked slots 8 that co-operate with the pointed ends of the standard healds 11 to shed the leno threads on alternate sides of the standard healds.  In Fig. 8 (not shown) a standard heald 11 may be raised so that its pointed end is above the top-most traverse of the leno heald and the appropriate leno thread is thus shed to one side only of the standard heald.

Abstract: 1488244 Centrifugal separator GES FUR KERNVERFAHRENSTECHNIK mbH 4 Aug 1970 [27 Aug 1969] 37685/70 Heading B2P [Also in Division H1] In the separation of isotopes, rotation of a plasma containing the isotopes is caused by crossed magnetic and electric fields. The apparatus comprises a chamber having a separation space 10 in which a hollow, cylindrical coil 26 is mounted for producing a magnetic field B s . Surrounding the space is an auxiliary coil arrangement 42 whose outer coils 42b are arranged to provide increased field strength at the end regions of the arrangement. Supported at one end of the coil 26 is a copper electrode 34. Current is supplied to the coil 26 and electrode 34 via conductors 32 enclosed in hollow, ceramic members 28, 30 which support the coil and electrode in the chamber. A second electrode 40, of larger diameter than the electrode 34 and movable axially into the space 10 constitutes a cathode and is made of uranium whose isotopes are to be separated. In operation, hydrogen (or helium) is pumped into the chamber and an arc struck between the electrodes 34, 40 to create a plasma. The uranium content of the plasma is progressively increased by moving electrode 40 into the chamber. Due to the frustoconical form of the field between the electrodes, a radial component of the electric field exists and cuts the axially-directed lines of the magnetic field to cause the plasma rotation and hence centrifugal separation of the light and heavy fractions. Electrode 40 can be cooled.
