IPC: A01F12/18
Filed: 1971-08-16
Abstract: 1297220 Harvesting machines DEERE & CO 16 Aug 1971 [14 Aug 1970] 38329/71 Heading A1F [Also in Division B8] In a harvesting machine which includes a rotating feed roller 4, and a plurality of conveyor fingers 7 which slide to and fro through respective finger guides 8 in apertures 15 in the roller wall, the finger guides consist of an annular body made of rubber or plastics material, and have a first flange 9 which lies on the outside of the roller wall and a second flange 10 spaced from the first flange and lying on the inside of said wall, the dimensions of the flanges being such that they provide the only means of fastening the guide within its respective aperture, and means are provided to assist in fitting the finger guide within its respective aperture. The assisting means may comprise the provision of a cut out 16 in the aperture to a depth corresponding substantially to the radial dimension of the bead. In a modification (Fig. 4, not shown), the second flange on the finger guide is provided at one point on its periphery with a slot, which extends approximately throughout the radial extent of the flange and extends obliquely across the flange at an acute angle to the parallel planes containing the flange. Two apertures (13) may be provided on the first flange 10 for attaching a turning-in tool in the form of a pin spanner.

Abstract: 1297363 Measuring angular position electrically PYE Ltd 19 April 1971 [6 April 1970] 16259/70 Heading G1N [Also in Division H1] Rotation of a shaft 1, which carries an annular magnet 5 and associated pole pieces 6, 7 varies a magnetic field provided by an air gap 8 relative to a magnetodiode 10 so that the effective resistance of the diode is dependent on shaft position. The diode is mounted between pole pieces 11, 12 and as shown in Fig. 3, may comprise a strip of intrinsic semi-conductor material 13 having p and n regions at the ends each provided with a lead. A zone 16 is treated so that combination of electrons and holes occurs more rapidly in this zone than elsewhere. Application of a magnetic field 19 causes deflection of the electrons and holes into this zone so that the through current is decreased. The resistance of the device will therefore depend on the magnitude and direction of the applied field. The diode is incorporated in a voltage divider circuit which may include a second similar but oppositely poled magnetodiode 21 in series with the first Fig. 5 (not shown), the two diodes being subject to similar conditions so that the output voltage across 10 is independent of temperature. The pole pieces may extend completely round the discs 3, 4 so that continuous rotation provides a sawtooth waveform output. By counting the maxima of such a signal and adding the intermediate fraction a measure of total rotation maybe found.

Abstract: 1301388 Semi-conductor devices LICENTIAPATENT - VERWALTUNGS GmbH 25 March 1970 [28 March 1969 (2)] 14545/70 Heading H1K [Also in Division H4] An electromagnetic transducer comprises a magnetic field diode and means for producing a magnetic field, the arrangement being such that a relative displacement between the diode and the magnetic field causes a change in resistance of the diode. The magnetic field diode is constructed as shown in Fig. 1 and comprises highly dioped N<SP>+</SP> and P<SP>+</SP> type regions 2, 3 on either side of a high-resistivity region 4 of N-, P-, or I type conductivity having a very long carrier lifetime within which is arranged a region 5 having a high recombination rate. A suitable magnetic field deflects carriers flowing between regions 2 and 3 into the region 5 where they recombine causing the resistance of the diode to rise. The semi-conductor material may be Si or Ge. Temperature compensation may be achieved by connecting a pair of diodes (6, 7) in series across a bias supply, Fig. 2 (not shown). The diodes are arranged so that their resistances vary in opposite senses when the magnetic field varies and the voltage across one of the diodes is applied to the input of an amplifier (8) which may be integrated in the same wafer as the diodes. Four diodes may be connected in a bridge circuit, Fig. 3 (not shown). The transducer may be used in gramophone pick-ups, Fig. 4 (not shown) and microphones, Fig. 5 (not shown).

The float members are free to pivot between two set positions determined by the motion of the craft and its leeway and each float has its centre of pressure, aft of or below the associated hinge axis so that with the wind from one side of the centreline the leeward float pivots to one set position to present a planing or hydrofoil surface to the water as the craft is seailed in a direction offset to leeward with respect to the centreline. The weather float then pivots to the other set position where it provides a leeboard surface aligned with the direction of sailing. Each float member is able to serve as a rudder and as shown in Fig. 4 each may have a hinged hydrofoil 13 and keel 12.

Abstract: 1326645 Quoits BRITISH ROPES Ltd 22 May 1972 [9 Sept 1971] 42200/71 Heading A6D A quoit is made from rope which includes strands made of or including thermoplastics material by fusing the ends of the rope together. As described a length rope is gripped (e.g. by adhesive tape or mechanical means) at two closely adjacent positions at each point where a cut is to be made so as to prevent unravelling when the rope is divided into lengths for quoits. A P.V.C. sleeve is passed over the rope length and the ends of the rope heated on a metal surface. The molten ends are brought together and held until set before sliding the sleeve of P.V.C. to cover the join. Immersion in hot water shrinks the P.V.C. sleeve. Preferably the strands of each end are aligned before joining so as to give the impression of a continuous rope.  The rope may be of twisted, longitudinally orientated polypropylene film or of extruded filaments of polyethylene, polyamide or polyester. Non thermoplastic material may be incorporated in the rope. Loading may be achieved by a lead wire at the centre of each strand. Different colours may be used.

Abstract: 1327951 Venting IC engine crank-case NATIONAL RESEARCH DEVELOPMENT CORP 21 June 1971 [19 June 1970] 29896/70 Heading F1B IC engine mounted in a gas-tight, pressuretight capsule has an exhaust gas recycle facility and has a compressor mounted in the capsule and connected between the crank-case interior to withdraw gas therefrom and feed it at an increased pressure into the line through which recycled exhaust gas mixed with oxygen is supplied to the engine. The engine 10 is contained in a capsule 10A and has a small compressor 43 connected to the crank-case breather 51. The compressor is driven continuously by a mechanical, hydraulic or pneumatic drive whenever the engine is being operated in the recycle mode. The compressor delivers into the intake passage 18 of the engine. On the intake side of the compressor is a spring- loaded ball type non-return valve 44 which opens to admit air from the interior of the crank-case whenever the air pressure in the capsule exceeds that in the crank-case by e.g. 1p.s.i. This prevents the pressure in the capsule rising above a predetermined value. In an example a rotary valve compressor delivering 3 cu.ft/min at 5 p.s.i. was used with a 3-cylinder four-stroke engine of about 150 cu. ins swept volume, developing 47 B.H.P. at 2500 r.p.m. In a modification, the relief valve 44 is omitted and a limited-discharge compressor is used, which has a compression ratio such that it will only deliver gas when the crank-case pressure exceeds a pre-determined value, say 15 p.s.i. for a pre-determined constant inlet passage pressure, say 20 p.s.i.
