Abstract: 367,372. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rex, H. B. ; 42, Magnolia Avenue, Lynn, Massachusetts, U.S.A.) Nov. 17, 1930, No. 34622. Convention date, Nov. 16, 1929. [Class 40 (i).] In means for indicating a deflection at a distant point, of the type in which a direct current proportional to the deflection is measured at the distant point, this current is produced from an alternating current source by means of a motor-controlled induction voltage regulator and a rectifier. As shown, the deflection of a measuring instrument 12 is represented by the movement of an arm 14, which is connected through line 15 to one side of an alternating current source 16. The arm 14 lies between two contacts 20, 21 connected through lines 22, 23, respectively, to windings 27, 26 of an electric motor 25. The motor is adapted to adjust the rotor element of an induction voltage regulator 24, which is connected, as shown, to a rectifier 29 and a direct current d'Arsonval instrument 17, the axis of which is in line with the shaft of the measuring instrument 12. Movement of the arm 14 causes a current to flow through one or other of windings 26, 27, whereby the motor 25 rotates in one or other direction to vary the signalling current through the circuit 11, until contact with the arm 14 is opened. One or more condensers 35 may be provided to smooth out the rectified current and a neon tube 36 is preferably connected across the signalling circuit for protection purposes.

Title: Combine harvesters
IPC: A01D41/14
Filed: 1974-08-09
Abstract: 1471971 Combine harvesters MASCHINENFABRIK FAHR AG GOTTMADINGEN 9 Aug 1974 [6 Sept 1973] 35264/74 Heading A1F A combine harvester comprises ground surface sensing apparatus 7 situated on the front part of a mowing table 1. A rearwardly directed curved sensing element 8 has a hub 9 at one end and is arranged to be pivotable about a transverse axle provided by a bearing pin 10 secured on the mowing table. A lever 18 is secured to a hub 13 which is also pivotably mounted on pin 10. Hub 9 is biased towards hub 13 by spring 15 and carries pins 14 which engage in recesses in hub 13 to form an overload clutch. The lever 18 is thus turned towards a limit switch 19H or 19S for lifting or lowering the mowing table. The switches are connected by means of an electric line 20 with a releasable electric coupling 21 to the control system of the harvester. Two adjustable abutments 22 are arranged either side of the lever 18 preventing damage that might otherwise be done to the switches 19H, 19S. If, after striking either abutment, the sensing element 8 is turned further, the coupling between hubs 9 and 13 is broken since the helical spring 15 is compressed as the sensing element continues to turn. An eye 23 on the sensing element 8 is connected to the chain 24 on the mowing table to permit transportation of the harvester. In order to ensure smooth transition in the mowing table height control arrangement even when coupling hubs 9, 13, are disengaged the lever 18 is always pressed against the limit switch 19H as soon as the hubs are uncoupled. Height adjustment is achieved by means of two cone shells which rotate relative to each other and which can be fixed by a clamping screw in any relative position that can be read off a scale (Fig. 5) calibrated to the cutting height. Abutment 11 stops the sensing element 8 swinging downwards to an excessive amount owing to its weight. In another embodiment a connection of telescopic tubular elements provides cutting height adjustment (Fig. 3-not shown).

Abstract: 389,930. Hydraulic apparatus for brakes and other purposes. RUBURY, J. M., Little East, Convent Hill, Bocking, Braintree, Essex. Dec. 23, 1931, No. 35536. [Class 103 (i).] In hydraulic transmission apparatus for brakes and other purposes such as described in Specification 365,069, comprising a piston c operated by a lever e or the like to apply pressure to a second piston d which forces liquid into the pipes leading to the brake &c. actuating cylinders and in which ports h for supplying liquid from a reservoir a to the space between the pistons are normally uncovered by the piston c, a spring i disposed between the pistons is adapted to transmit sufficient pressure from the piston c to the piston d to prevent substantial hydraulic pressure building up in the space between the pistons until the cup-packing f of the piston c has passed the ports h. Damage to the cuppacking f by exposure to high fluid-pressure while covering the ports h is thus avoided. As shown, the piston d has a spring-loaded non-return valve past which liquid is forced if the piston d reaches its end position before the brakes are applied or the liquid may pass through a hole in the piston and along the outside of the cup-packing of the piston. To prevent excessive pressure in the pipe lines, a non-return valve k may be provided to allow return of the liquid. The piston d may be of smaller or as shown, of larger diameter than the piston c. In the latter case a boosting effect is produced on piston d during the first part of the travel, that is, until the brakes are applied.

Title: Improvements in or relating to electric signalling systems
IPC: H04Q1/446
Filed: 1933-12-20
Abstract: 430,502. Distinguishing A.C. signals from voice currents &c. STANDARD TELEPHONES & CABLES, Ltd., SKILLMAN, T. S., and ROCHE, A. H., 63, Aldwych, London. Dec. 20, 1933, No. 35897. [Class 40 (iv)] Several arrangements are described for rendering the operation of a receiver of alternating current signals comprising two or more frequencies dependent on the relative energy levels of the component signalling frequencies and of the extraneous frequencies which may be present in speech or noise. In Fig. 1, received currents are amplified by valves V1, V2, the second of which acts as a volume limiter by virtue of the condenser C and leak L connected to the grid. A filter F1 passes the signalling frequencies, e.g. 600 and 750, to a bridge rectifier BR and a low-pass filter F2, and the 150-cycle output from the latter effects the operation of a relay R through a valve V3. Since the total output of the valve V2 is substantially constant, the energy level of the signalling frequencies is reduced when other frequencies are present, and it may be arranged that operation of the relay R is prevented when the energy of the extraneous frequencies is from a quarter to a third of the total energy. In Fig. 2, the output of the limiting valve V2 passes to four parallel tuned circuits G1, G2, S1, S2 which control relays GR, IR, HR through bridge rectifiers BR1-4. The guard circuits G1, G2 are tuned to frequencies of 500 and 900 and operate the relay GR if either or both of these frequencies are present at a sufficiently high level. The circuits S1, S2 are tuned to the signalling frequencies 600 and 750. It is arranged that the output of the valve V2 contains not more than three times the energy necessary to operate either of the relays IR, HR, consequently the energy distribution between the two signalling frequencies for correct operation depends on the energy of extraneous frequencies; if the latter comprises a third of the total energy, the levels of the signalling frequencies must be approximately equal. In Fig. 3, the limiting valve V2 feeds tuned circuits controlling relays IR, HR, as in Fig. 2, and a third winding of the inter-valve transformer T is connected to parallel tuned circuits L1, C1 and L3, C3 which form partial short-circuits for the signalling frequencies when extraneous frequencies are present. In Fig. 4, the two signalling frequencies are directed through tuned circuits F1, F2 to valves V1, V2 respectively, and each anode circuit includes a winding of relays R1, R2. The relay R1 has opposed windings, while the relay R2 has aiding windings, so that the energy of the two frequencies must be approximately equal for correct operation.
