Abstract: 119,743. Langsdorf, W. Nov. 17, 1917. Potat¾ - diggers. - In a potato-digger of the type in which the potatoes are thrown out of the ridges by forks f mounted on members carried on and rotated by a star crank e, the axis of which is parallel with the fork-supporting members, these members are connected to the star crank by arms adjustable in slots in the crank so that the sweep of the forks may be varied. The machine, which may be either self-propelled or horsedrawn, is supported on wheels a and suitable gearing driven from the axle of these wheels is arranged to rotate the star crank e carrying the fork-supporting members. The ends of these members are connected to guided wooden rods h whereby the motion of the forks is brought to resemble hand digging. The forks are arranged in front of the crank and may be arranged to be adjustable in a fore-and-aft direction. Notches may be formed on the arms to facilitate adjusting them to the same degree. An adjustable share g may be arranged in front of the forks.

Abstract: 750,327. Radar; radio signalling. PHILIPS ELECTRICAL INDUSTRIES, Ltd.. June 22, 1953 [June 25, 1952], No. 17220/53. Classes 40 (5) and 40 (7). In a radar navigation system for piloting ships or aircraft comprising a ground control pulse radar station 1 (pulsed amplitude or frequency) with a rotating directional aerial 6 displaying the position of the craft on a P.P.I. 4 and communication transceivers 8, 9 and 22, 23, operatng on a different wave-band from the radar and located respectively at the control station and on each craft for the transmission and reception of pilotage instructions, an auxiliary receiver 36 tuned to the radar frequency is provided on each craft which in conjunction with the craft and control station transceivers enables a particular craft response on the display to be identified. The auxiliary craft receiver 36 comprises selectable R.F. filters 39, 40, 41, a detector 42 and a bandpass filter and limiter 43 tuned to the radar recurrence frequency, e.g. 3,000 c/s, so that as the radar beam sweeps past the craft, filter 43 produces a train of 3,000 c/s sinusoidal oscillations whose duration is dependent on the beam width and rotation rate of aerial 6. When identification is required this oscillation train is applied via change-over switch 44 to the bandpass audio input 25 of the craft communication transmitter 22 and at the control station it is applied from the audio output stage 20 of communication receiver 9 via change-over switch 45, filter 46 (3,000 c/s) and rectifier 47 to open a gate circuit 49 which applies highfrequency oscillations, e.g. 1-3 Mc/s, from oscillator 48 to intensity modulate the radial trace of the P.P.I.; alternatively the output from filter 46 may be applied directly to intensity modulate the display.

Abstract: 964,652. Variable resistors. STANDARD TELEPHONES & CABLES Ltd. (International Standard Electric Corporation). May 2, 1963, No. 17373/63. Heading H1S. [Also in Division H2] The Specification discloses a variable resistor whose resistance varies smoothly from about 0.2 to 5 ohms for controlling EHT voltage and picture width in a television receiver (see Division H2 and Fig. 1, not shown). A moulded carbonaceous disc 65 is supported on a metal bracket 60 which also forms one terminal and has lugs 67 arranged to fit recesses in the disc. A conical spring 78 of conducting material is pressed against the disc by the insulated adjusting screw 70, so that movement of the screw 70 varies the area of contact between the ring and the disc. The base end of the spring is located in a recess 82 in the disc to prevent rotation. This construction allows the resistor to dissipate as much as six watts in heat.

[Classes 39 (i) and 40 (v)] A thermionic mixe: valve has at least three grids between cathode 1 and anode 8 and two adja cent grids 2, 3, Fig. 1 which act as control grids are provided with screens 6 which extend betweer the parts of the grids near the support rods and are connected to the cathode or to a point of fixed negative potential. By dispensing with the usual positive screening grid between the control grids, the valve noise is reduced. Preferably the turns of the second control grid 3 and the third screening grid 4 are aligned. A suppressor grid 5 is provided. In the circuit shown in Fig. 2 a separate triode 9 generates the local oscillations which are applied to the second control grid 3, the incoming signal from circuit 21 being applied to the inner grid 2. To compensate the presence of local oscillations on grid 2 induced electrostatically from grid 3, a reversed phase component taken from the anode circuit of triode 9 is applied through variable condenser 24 and resistance 25 to the grid 2. The triode may be incorporated in the valve 10 and may use the same cathode.

Abstract: 758,772. Aerials. BELLING & LEE, Ltd. May 20, 1955 [June 16, 1954], No. 17694/54. Class 40 (7). An aerial system intended for operation in resonance on two frequencies comprises two aerials for the higher frequency, consisting of quarter wavelength extensions of the inner conductor of a coaxial line, which are supported collinearly at the extremities of a member or members forming a half-wave aerial element at the lower frequency. As shown, the lower frequency aerial element consists of two members 10 supported centrally in an insulator (not shown) and having their inner end connected to a feeder 11. The higher frequency aerials consist of outwardlyextending quarter-wave elements 13 and quarter-wavelength sleeve portions 12 surrounding the extremities of the members 10 and attached to them at their ends. The elements 13 are connected together by a conductor 14 coaxial with the members 10 and forming with them a matching transmission line. It is stated that the higher frequency aerials are effectively coupled to the transmission line 11 in the construction shown. If desired, however, separate feeder arrangements can be provided for the signals of the two frequencies; or a common transmission line may be coupled to symmetrically spaced points on conductor 14 by a delta matching section, the lower frequency element in this case being continuous (Fig. 2, not shown). Instead of sleeves 12, ground plane systems for the elements 13, consisting of radially extending groups of rods, discs, or the like may be provided. In reckoning the length of the lower frequency aerial element the effect of the sleeves or ground plane members must be allowed for. The two frequencies to be handled should differ by a ratio of more than 2: 1.
