[Class 4] Automatic steering - gear for aircraft, in which indications of the course are transmitted from the compass to the rudder by means of electric contacts, photoelectric cells, or gyroscopic devices, through two electric circuits controlling the servometer through a system of lever and pawl devices, comprises two wheels 21, 2<11> continuously rotated in opposite directions by the aircraft engine or an electric motor through pinions 7 and endless screws 5<1>, 5<11> and a central grooved-pulley 1 loose on a shaft 4, and to which is secured by a pin 9 a ruddercontrol rope and two electromagnets 13<1> 13<11> mounted on the pulley 1 for controlling in clockwise or anticlockwise direction one or other of two pawls 16<1>. Movement of an indicator 42 closes a circuit through one or other of two adjustable contacts 43<1> 43<11> to energize respectively either one of electromagnets 44<1>, 44<11> and move a core causing a contact 35 to close a circuit to energize one or other of the electromagnets 13<1>, 13<11>. Energization of the magnet 13<1>, e.g. moves its core 121 to the left locking a lever 10<1> against the action of a spring 14<1> to release one end of a rocking pawl 16<1> mounted on the pulley and allow a spring 15<1> to rock the pawl to cause engagement with teeth 6<1> on the wheel 21 thus causing the wheel 2<1> and pulley 1 to rotate together until the pawl engages a stop 191 to disengage the pawl and allow the pulley to be brought to its initial position by springs. The pulley carries three electrically insulated brushes, one of which contacts continuously whilst the other two only contact until the pawls are unlocked. Simultaneous engagement of the pawls is prevented by means of two levers mounted one on each end of a spindle passing through the pulley and provided at their free ends with rollers bearing against and actuated by the levers 10<1>, 10<11>. A hand lever may be provided, which, when placed in one or other of two extreme positions closes a circuit through one or other of the electromagnets to effect steering of the craft.

Title: Improvements in electrically operated apparatus for the automatic control of power operated track vehicles
IPC: B66C15/00
Filed: 1944-03-07
Abstract: 577,226. Automatic control apparatus for power-operated track vehicles; collector shoes for electric current. SHAW, H. March 7, 1944, No. 4210. [Classes 104 (iii) and 105] Apparatus for giving a warning signal on and stopping an electrically propelled track vehicle such as an overhead travelling crane comprises a normally energized control circuit on the vehicle with its current of a low voltage derived from the power supply for the motor and including a relay and contact shoes engaging a sectionalized conductor rail for control purposes, the relay being de-eneigized when two contact shoes are on separate sections of the control rail which have been isolated from each other by the manual opening of a switch, such de-energization of the relay causing the release of the controller for the drive motor or otherwise effecting the stoppage of the vehicle, there being also manual switches in the control circuit whereby this circuit can be broken at will and the sectionalized conductorrail can be earthed so that any other vehicle will be automatically stopped. A control relay F is energized from a low-voltage halfwinding of a transformer D over a line D<3> (which includes certain emergency switches) contact shoe E, control rail A, contact shoe E<1>, line D<4> and earth return. The control rail A has its sections connected by switches B<1> but when it is desired to prevent entry into a section such as section 2, as when work is being carried out in that section, the switch B<1> is opened so that the relay F becomes de-energized and opens its front contact which is included in a stick circuit for the controller I of the drive motor which is therefore stopped ; an alarm 12a is sounded from the other half-winding of the transformer over line 10, 11, back contact 12 of the relay F and earth return. The driver may, however, proceed or back out by pressing a reset button K for the controller I of the drive motor and maintaining a button J pressed, the latter effecting the energization of the relay F to close its front contact whereby the controller I is picked up over button K and is thereafter held over a stick contact. A driver of one vehicle may stop a approaching vehicle by depressing a switch L whereby contact shoe E and control rail A are earthed so that on the approaching vehicle the shoe E thereof is earthed and the relay F thereof is therefore short-circuited to earth and thus de-energized to stop the motor ; the alarms 12a are sounded on both vehicles. An emergency stop button H is included in the relay circuit and the alarm may be tested by depressing a button O. The end sections of the control ail are gapped at C. The contact shoes E, Fig. 2 and 3 are supported from insulation blocks 24 by parallelogram spring arms 25 and guided by studs 27 sliding in metallic bushes 28 in such blocks.

Title: Antistatic plastics compositions
IPC: C08F2/02
Filed: 1966-02-01
Abstract: Antistatic plastics compositions comprise a carbonyl-containing polymer and, as an antistatic agent, lithium perchlorate distributed substantially uniformly throughout the polymer. The term "carbonyl-containing polymer" is used to include polyesters, polyamides, polycarbonates, polyvinyl acetate and acrylic polymers; examples of the latter are homopolymers or copolymers of acrylate and/or methacrylate esters, particularly the C1-C8-alkyl esters.  The compositions may include additives such as plasticizers, fillers, pigments, e.g. carbon black, dyes and stabilizers and can be shaped to form articles, e.g. sound-reproduction records.  In the production of the acrylic compositions, the lithium perchlorate can be introduced in the acrylic monomer, which is then polymerized in bulk, solution, emulsion or suspension using an anionic initiator or a free radical initiator such as lauroyl peroxide, 2,4-dichlorobenzoyl peroxide, azodiisobutyronitrile, benzoyl peroxide, acetyl peroxide and t-butyl peroxyisobutyrate. Bulk polymerization may be effected in a mould.
