Title: Improvements in tractors
IPC: B62D49/06
Filed: 1945-04-27
Abstract: 617,956. Tractors. BOBARD, E. April 27, 1945, No. 10619. Convention date, Feb. 21, 1942. [Classes 79 (i), 79 (iii) and 79 (iv)] [Also in Group I] A three-wheel tractor comprises a front driving and steerable wheel and a U- or V- shaped frame, the two arms of which each carry a rear trailing wheel and are spaced so that a trailer may be coupled between such arms to a draught arm of the tractor, which draught arm partially embraces the periphery of the front wheel, whereby the coupling is located in front of the rear axle. The Figures show a three-wheel tractor having a front motor wheel 4 and two rear wheels 9 and 9<SP>1</SP>. The wheel 4 is rotatable within a fork 3, steerable by a wheel 7 and bevel gears 8, 8a within the headstock 2 of the tractor frame which is U-shaped having rearwardly disposed arms 1, 1<SP>1</SP>. Attachment means for three ploughs are provided at the points 10, 10<SP>1</SP> on the rear wheel stub axles and on a draught arm 12 located behind the front wheel 4, partially embracing the periphery thereof. The depth of the ploughs may be adjusted by a handle operating levers 11. In a modification, Fig. 4, the tractor frame may comprise two tubes 13, 13<SP>1</SP> on which the side members 1, 1<SP>1</SP> are adjustable laterally. The tractor may be adapted to tow a trailer, the connection between the two being made by a hook 24 on the trailer, Fig. 5, engaging a pin 12a on the draught arm 12. To effect coupling, the tractor is reversed, the rear wheel axles of which engage the sloping ramps 29 and ride up over them, at the same time the hook 24 engaging the pin 12a; or the abutment 28 on the tractor may engage the front portion 27a of the trailer arms 27, whereby the tractor is rotated anti-clockwise about its wheel 4 to lift its rear wheels 9 off the ground and to engage its pin 12a with the trailer hooks 24. The lever 31 is then actuated to clear the legs 30 of the trailer from the ground and to lock the hooks 24 on the pin 12a. Thus coupled, the weight of the combination is thrown on to the front wheel of the tractor, providing better wheel adhesion with the ground. For heavier towing loads, two tractors may be coupled together, as in Fig. 10, so that they are rigid together in a lateral sense, but may pivot in a vertical plane about the two points 44 and 40a, the front wheel of the rear tractor being in alignment with the rear wheel axle of the front tractor; the rear wheels may be removed if desired.

IPC: H02K21/16
Abstract: 107,005. Diem, E. C. May 23, 1914, [Convention date]. Void [Published under Sect. 91 of the Act]. Magneto-electric machines; coils; cores and yokes; exciting.-According to the Specification, as open to inspection under Sect. 91 (3) (a), the armature winding of an alternating-current generator is designed with a resistance negligible compared with its inductance so that with variable speeds of driving a practically constant current is obtained without the use of any means of regulation. One form of alternator comprises a fixed outer armature 1, Fig. 1, with coils 4 of insulated copper wire or band; a multipolar field magnet is constituted by a number of star-shaped plates 10 having alternate North and South poles and either permanently magnetised or wound with exciting coils. A field magnet of the kind shown in Fig. 7, having imbricated poles, may be used, the coil 7 being excited by continuous current shunted from the line through a rectifying commutator having stationary commutator segments 17 and rotating brushes 16; or a synchronous vibrating rectifier may be employed. The main armature current may be used to charge batteries, for instance, on motor-vehicles, by the employment of similar rectifiers. In cutting out lamps from the main circuit, it is necessary to replace these by an equivalent resistance; this may be effected by the use of a two-way switch for each lamp. A part of the main current may be supplied through a transformer to ignition apparatus for internalcombustion engines.

Title: Improvements relating to the automatic steering of ships
IPC: G05D1/02
Filed: 1936-04-14
Abstract: 478,344. Automatic control systems. SPERRY GYROSCOPE CO., Inc. April 14, 1936, No. 10732. Convention date, April 13, 1935. [Class 38 (iv)] Steering.-In the automatic steering of ships a variable speed controlling device, the speed of which is maintained proportional to the relative velocity of turning between the directional instrument, e.g. a gyro-compass, and the ship, applies control to the rudder in addition to that due to the relative angular position of ship and compass. The extent of this additional control may be adjustable and means may be provided whereby it may be rendered inoperative, or reversed in order to diminish rudder throw for rapid rates of yaw. As shown a rudder R is adjusted by a reversible motor 65 from a main controller 33 which has a follow up connection to the rudder and is operated through a self-synchronous electrical transmission actuated from a worm wheel 31. The worm 32 receives rotary motion from a follow-up motor 5 energized through a compasscontrolled controller 1 by way of gears 5<1>, chain drive 8, differential 21 and elongated pinion 28. A course setting knob 18 is coupled to the differential gear. The additional rudder control is effected by longitudinal movement of the worm proportional to the rate of relative turning of ship and compass. The integrated movements of the motor 5 turn a nut 48 engaging a screw on a shaft 44 suitably coupled to the worm shaft and causing displacement whereby the shaft 44 is rotated at a speed equal to that of the nut by friction gearing. This may comprise a disc 50, rotated by an electric motor 51 at a speed which can be adjusted, as by a potentiometer 59, according to the degree of additional rudder control desired, and friction wheels 55, 54 forming part of a differential gear causing rotation of the shaft 54 on displacement. An alternative form of friction gear comprising a two-ball integrator is also described. To cut-out the additional control or reverse its action a reversing clutch 47 is provided. Specification 478,421 is referred to.

Title: Improvements in and relating to unicrystalline oxide material
Inventor: JACK KENNETH HENDERSON
IPC: C30B29/26
Filed: 1963-03-19
Abstract: Unicrystalline metallic or silicon oxide material is produced by feeding a volatile compound of a metal or of silicon as vapour, optionally in a carrier gas stream, into a high temperature oxygen-containing gas stream, and collecting the oxide or oxides formed on the molten surface of a seed-crystal.  Typical <PICT:1058773/C1/1> <PICT:1058773/C1/2> starting materials are ferric chloride, aluminium chloride, aluminium bromide, titanium tetrachloride, silicon tetrachloride, tetramethyl silane, chromyl chloride, vanadium tetrachloride and iron pentacarbonyl.  Typical products are sapphire, ruby, corundum, rutile, mullite and chromium oxide.  In a process for producing rutile (Fig. 1), a stream of dry hydrogen passing through tube 1 picks up TiCl4 from the liquid TiCl4 in chamber 2.  The feed stream passes through tube 7 and mixes with oxygen and hydrogen fuel gases entering at 8.  The product crystallizes on seed crystal 9.  In a process for producing ruby (Fig. 2) aluminium rod 14 is chlorinated by burning chlorine from 12 in hydrogen from 13.  Hydrogen carrier gas from 17 sweeps the aluminium chloride into the oxyhydrogen burner 16, the hydrogen and oxygen being fed through 19 and chromium oxide being introduced as chromyl chloride vapour via 20.

[Also in Divisions A1 and G1] A combine harvester includes primary and secondary grain cleaning apparatus and means for checking the efficiency of the grain cleaning process by measuring the rate of flow of cleaned grain discharged from the secondary grain cleaning apparatus. The means includes ducting closable, to form a container, by a flap controlled to open and close at predetermined intervals of time or to open to discharge grain when the ducting holds a predetermined amount. The ducting may consist of two parallel ducts with means for selectively directing the flow of grain into one of the ducts so that one duct may be discharging while the other is filling. A detector for determining the quantity of grain in the ducting comprises a transmitter and receiver mounted at opposite sides of the ducting. The transmitting and receiving device may be a photo-electric or piezo-electric device or ultrasonic transducers. The detector means may include an indicator for displaying the rate of flow of the grain through the ducting, a signal amplitude comparator between the receiver and indicator, a peak-hold unit associated with the indicator to maintain a steady reading thereon and a timing device which registers the time required to collect a predetermined quantity of grain. The timing device comprises a source of constant amplitude electric current and a capacitor which charges while grain is entering the ducting so that the resultant charge on the capacitor is a measure of the rate of flow of grain. The detector means may comprise an electromechanical transducer (Fig. 6, not shown) with a diaphragm projecting into the ducting against which grain impinges. The transducer is connected via a half-wave rectifier and a transistor amplifier to an indicator of variable sensitivity. The inside of the ducting has corrugations or inwardly projecting deflectors to randomize the flow of grain, the transducer diaphragm being located at an angled joint in the duct. The secondary grain cleaning apparatus 6 includes a shaker shoe, a perforated tray, a fan and an exhaust duct for the removal of straw and waste material. A grain saver device 4 as described in Specification 1,101,431 is also included.
