Title: Tractor driven agricultural implements
IPC: A01B69/06
Filed: 1954-07-14
Abstract: 797,132. Agricultural implements. LARSEN, H. S. B., [trading as MASKINFABRIKEN TAARUP VEHELGE LARSEN]. July 14, 1954 [July 16, 1953], No. 20515/54. Class 6(1). In a tractor-drawn agricultural implement which has a tool-supporting frame 9 connected to the tractor 3 by lifting rods 5, 6 connected to the tractor and the frame by ball joints at spaced points at each end, and which has ground wheels 17 which can be turned together about vertical axes by a control handle 22, the frame 9 has a releasable adjusting device by which the lifting rods can be swung in a  horizontal plane and the frame 9 displaced transversely. This enables the tools 16 to be adjusted relatively to the plant rows when the implement is lowered for use. In the form shown, movements of the steering arm 22, which is fixed to a vertical shaft, are transmitted by a second arm 20, also fixed to the shaft, to a rod 19 connected to arms 18 by which the wheels 17 are turned. An arm pivoted to the same shaft is connected by a link 33 or 37 to the lifting rod 5 or to the tractor body, and can be locked to the shaft by a spring-pressed pin so that movements of the steering arm produce the lateral movements of the frame 9. The spring-pressed pin is actuated through a linkage by a lever on the steering arm 22.

In an arrangement for bringing a plurality of received signals into a predetermined phase relationship, e.g. in a diversity system, signals received via spaced aerials 90, 92, 94, 96, Fig. 1, are supplied to mixers 100, 102, 104, 106 respectively and heterodyned with a common signal supplied via line 108 from the output circuit. Considering mixer 100, the difference frequency is selected by filter 110, limited at 120 and fed to a mixer 130 which has as its other input the received signal applied to mixer 100, the outputs of mixers 102, 104, 106 being similarly treated and fed to mixers 132, 134, 136 respectively. The limiters may be omitted to provide "ratio squared" combining. The outputs of mixers 130, 132, 134, 136 are added at 140 and the sum frequency is selected by a filter 142, amplified at 144 and fed to the output stage and also fed back via lead 108 as the common heterodyning signal. The arrangement is applicable to frequency-modulated signals. The received signals may be in frequency-diversity form if the filters 110, 112, 114, 116 are tuned appropriately.

Filed: 1919-08-25
Abstract: 166,244. Leicester, A. E. Aug. 25, 1919. Levels, regulating.-A valve apparatus for maintaining a constant level of liquid in a tank or for delivering predetermined measured quantities, has an inlet valve actuated by variations of air or gas pressure within a closed container automatically controlled by the height of liquid in the container, which height is determined by an adjustable vent for the air or gas. A tank 2 fitted with a valve 8 communicates with an open tank 5 by a pipe 4 and a vent pipe 7 the length of which is adjustable by means of a sleeve. Liquid enters the tanks through the pipe 3 and valve 8, and after the vent pipe 7 has been sealed the pressure rises in tank 2 and gradually closes the valve 8 by acting on the diaphragm 10. In a modification, a single closed tank is used and the vent pipe has an adjustable pivoted arm connected to an indicating pointer. A three-way cock is fitted to the pipe 3.

Title: Improvements in or relating to pressure casting-machines
IPC: B22D18/02
Filed: 1934-07-18
Abstract: 441,549. Casting-machines. NORWOOD, C. R., Northwell House, Heptonstall, Hebden Bridge, Yorkshire. July 18, 1934, No. 20984. [Class 83 (i)] Metal, pouring.-In casting metal or other material contained in dish d into a mould a, these are moved relatively, in a vertical direction, and the material is released before, or during, or partly before and partly during said movement. In the machine shown the table b carrying the mould a &c. is first pulled down, against the action of springs b3, by a rack b<4>, pinion b<5>, and hand wheel i<6> and is then held by a spring pawl k. The dish d is filled with molten material and the wheel i <6> is then moved to the right, thus withdrawing the pinion b<5> from the rack and, by linkage i, g<2>, g, pulling down a socket f, and rod e therein, thus tilting the dish d and discharging part of its contents. Further movement of the wheel i<6> acts, through a lever m, to withdraw the catch k and allow the table b, carrying the dish d and mould, to move rapidly up, the drag of the socket f on the rod e causing the dish to be tilted as shown. In modifications the mould is projected upwards towards a stream of liquid material allowed to fall freely by gravity or the mould is stationary and the container is moved, or allowed to drop, vertically towards it and is arranged to tip or release its contents when it has reached a definite position relative to the mould.

Title: Parametron
IPC: H03K3/47
Filed: 1963-05-28
Abstract: 1,044,340. Magnetic storage devices. SPERRY RAND CORPORATION. May 28, 1963 [June 8, 1962], No. 21180/63. Heading H1T. [Also in Division H3] In a parametron circuit a current having a D.C. bias component and an A.C. component superimposed thereon at a frequency fp is applied to an anisotropic thin magnetic film 10 via a pump winding 16 having its axis parallel to the " hard " direction of magnetization of the film, and the film is provided with an output winding 22, forming part of an output circuit tuned to a frequency f p /2, and a further winding 18 which latter winding has its axis displaced from the " hard " axis so that when energy is applied to the further winding and the pump winding parametric oscillations having one of two different phases are induced in the output circuit. Output winding 22 has a capacitor 24 connected across its terminals so that the resonance frequency of the output circuit is f p /2, load 26 being connected across the capacitor. A small signal source 28 is coupled by transformer 30.to the output circuit and serves to determine with which of the two phases the oscillations take place. As the pump source field varies sinusoidally about its D.C. bias, Fig. 4 (not shown), the film 10 is driven alternately from saturation in one " hard " direction to its opposite " hard " direction. During the time the pump voltage changes direction the magnetization of the film returns to the " easy " magnetic direction by uniform rotation since the magnetic moment of the film is displaced from the hard axis in excess of a critical angle i.e. 5 to 25 degrees. The displacement of the magnetic moment is achieved by means of winding 18 whose axis is orientated at an angle of 40 degrees with respect to the hard axis and which is energized from pulse source 20. Parametric oscillations are thus induced in the output winding, which oscillations take place at a phase of 0 or # dependent on the phase of the locking signal from source 28. To turn off the oscillations to place the device in its stable non- oscillating state a suitable trigger pulse is applied from source 20 to the winding 18 so that the moment of magnetization is orientated towards the " hard " axis and the moment returns to the " easy " direction non-uniformly, thus preventing parametric oscillations from taking place. Thus the circuit has three stable oscillating conditions and can be changed from one state to another by appropriate choice of the phase of the signal from 28 and the polarity of the triggering pulse from source 20.

Abstract: 903,437. Automatic train control. BRITISH TRANSPORT COMMISSION. Oct. 6, 1958 [July 4, 1957], No. 21228/57. Addition to 818,751. Class 105. Train apparatus which co-operates with track magnets to effect train control by brake application or cab signals comprises a Hall voltage generator cemented between polepieces and supplied from an A.C. source at 3000 c/s., a magnetic bias coil wound on the polepieces and a transistor amplifier and rectifier arrangement which receives an input from the Hall generator and supplies a D.C. output to the bias coil. The arrangement is self-sustaining and also provides an output to an E.P. coil which holds off the train brakes. On passing over a first magnet at a signal location which is polarized to produce a flux across the generator which opposes the bias flux, the generator output rises, then falls to a zero value. If a second track magnet, which is polarized to produce a flux across the generator in the same direction as the bias coil, is not energized (danger or caution signal) the output of the generator remains at zero and after a delay determined by a condenser across the E.P. coil the brakes are applied. If the magnet is energized (clear signal) the self-sustaining operation is restored and the brake application is withheld.
