Abstract: 741,343. Harvesting root-crops. JONGENEEL, A. M. Sept. 25, 1953, No. 26481/53. Class 6 (3). Relates to a beet-harvester of the type described in Specification 668,813, wherein beets are picked up by a spiked wheel 3 and topped while carried thereby, the beets being carried away by an elevator 7 and the tops being discharged laterally by a transverse conveyer 6. According to the invention, the topping mechanism includes a rotary disc 15 at a level above the elevator 7, the disc supporting the topped beets and tending to move them in the direction of the elevator, and a driven auger 38 being provided just above the disc to transfer the beets to the elevator. The topping unit comprises a pair of discs 15, 22, each disc being mounted on a spindle 14, 21 carried by a sleeve 13, 20, supported by arms 12, 19 on a second sleeve 11, 18 rotatable on a pillar such as 8, carried by the sub-frame 2 of the machine. The discs are therefore swingable about their respective pillars and can separate on encountering obstructions, a spring 23 being provided to urge them into overlapping relation. A belt 17 drives both discs through pulleys 16, 33 and a further belt 35 drives a spindle 29 which drives the auger 38 through bevel gears. The auger comprises a skeleton thread 42 supported in spaced relation to a cylindrical core 41, this arrangement serving to break up clods which fall on to the conveyer 6. A retaining plate 44 extends upwardly from the auger and a deflecting plate 46 prevents topped beets from being carried round by the disc 15.

Abstract: 922,758. Bale sledges. A. W. SAUNDERS, and P. SAUNDERS. July 29, 1960 [Aug. 4, 1959], No. 26616/59. Class 94(1). A bale sledge comprises an elongated enclosure for a load of bales having a gate 36 at the back of the sledge and means for automatically opening said gate when the sledge is filled with bales a shoot 12 at the front of the sledge, the rear of said shoot being arranged above the ground a distance not less than the depth of a bale, whereby when a first row of bales has been placed in the sledge, a second row of bales can be applied on top of the first row. The shoot 12, attached to the cross-bar 10 of the enclosure is provided with a brake 30 to retard falling of the bales into the sledge. The gate comprises a box 36 hinged at 38 and held in a closed position by a lever 40 which is connected through a rod 52 and a cross-bar 56 to a trip lever 58. In use, a bale is pushed through the shoot 12 falls on to the floor bars 70 of the sledge and rests on the ground, but due to the forward motion of the sledge it is caught at the gate 36. This continues until there are four bales on the floor, and four bales on top of these. When the eighth bale has passed through the shoot it causes the fifth bale to move against the the trip lever 59, thus opening the gate, and the eight balls are discharged together. A cord 55 is attached for manual operation of the lever 58. A pair of wheels 61 are mounted at the ends of a support 62 and may be raised and lowered. The floor of the shoot may be adjusted to accommodate different sized bales.

Title: Improvements in or relating to circuit arrangements for evaluating overlapping input signals
IPC: H03K5/26
Filed: 1965-06-25
Abstract: 1,106,012. Electric selective signalling. SIEMENS A.G. 25 June, 1965 [26 June, 1964; 5 Aug., 1964], No. 26923/65. Heading G4H. A circuit arrangement comprises a number of input channels, each connected to an individual store, and a common drive unit which is triggered, on reception of a signal on any one input channel, to apply a check signal to all the stores after a given time, the check signal producing an output signal in that one channel, although other earlier input signals may still be present and provided that no subsequent input signal has been applied before the end of the check signal. The arrangement can be used to avoid errors in operating the keyboard of an electric typewriter or the like. In a first embodiment if an input signal is applied to a primary winding W1, Fig. 1, of a magnetic core K with a rectangular hysteresis loop by closing a switch Ts the bias current in that winding W1 (or a second winding W3, Fig. 2, (not shown)) is reversed to provide an output pulse on winding W2 to a transistor Tr which applies the pulse to a core store Zs and a timed checking arrangement Ag, Zg. Each channel has an associated core K and transistor Tr. After a predetermined time interval a pulse is applied to all the stores Zs and only that one just set produces an output which may be coded at Aw. If more than one signal is produced during the time interval a monitor Ks blocks the coder Aw and operates an error-indicator Az. In a second embodiment each input core acts as its own store Zs, each core carrying a biasing winding W1 (Fig. 3, not shown) and an input winding W2 which when pulsed moves the working point of the core to its positive remanence value whereby the checking pulse produced after the predetermined time interval triggers the core from its positive remanence point to a negative point producing an output pulse only from that core storing input information, which output is applied to the coding and monitoring circuits Aw, Ks. In order to evaluate up to four inputs arriving in time-overlapped fashion and also to indicate a congestion fault the drive unit Ag of the timed checking unit comprises five cores with bias windings (W1), (Figs. 4, 4a, not shown), having progressively greater number of turns whereby input pulses on second windings (W2) trigger the cores successively to give four checking pulses (Zg). The fifth pulse drives a transistor (Tr2) to indicate a congestion condition. Instead of closing a switch to represent information, the switch may be opened, (Fig. 5, not shown), whereby the biasing current is removed and the core subsequently triggered by the checking pulse. Instead of a single output winding a plurality may be provided, interlaced through the cores in a coded formation, a two-in-five and one-in-four code being described.

Abstract: 269,492. Compagnie GÚnÚrale d'Electricite. April 19, 1926, [Convention date]. Insulating coverings for cables. - Relates to cables of the kind comprising one or more conductors surrounded by an insulation of impregnated paper or fabric and enclosed in a lead sheath. According to the invention, spaces are provided between the insulation and the sheath through which impregnating fluid is circulated in order to ensure that the insulation is filled with the fluid regardless of variations of temperature. For this purpose a strip 3 of paper, jute or other suitable non-conducting material, is wound helically over the insulation 2 so as to leave a cavity 4 between the insulation and the sheath 5. In the use of the cable, a reservoir containing impregnating fluid is placed in communication with the cavities, and means are provided for submitting the fluid to pressure in order to ensure that the cavities are always full. The Specification as open to inspection under Sect. 91 (3) (a) describes a construction in which cavities are formed by grooves in the inner surface of the lead sheath, the helical winding of ,jute, etc., being dispensed with. This subjectmatter does not appear in the Specification as accepted.

Abstract: 802,331. Transistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 23, 1955 [Sept. 28, 1954], No. 27183/55. Class 37. A transistor comprises a semi-conductor body consisting of two adjacent zones of opposite types of conductivity to one of which an ohmic base contact and rectifying emitter and collector point contacts are connected and to the other of which a single large area ohmic connection is made so that the junction between the zones may be reverse biased. In the embodiment the body 1 is of Ge or Si with the junction 4 extending parallel to the face on which the emitter 7, electroformed collector 8, and ohmic base contact 5 are situated. The junction is reverse biased by a negative potential applied to the solder layer 6, to provide a depletion region in the N-type zone 2. This region absorbs stray carriers and produces an increased field between the collector and base electrodes thereby reducing and making more uniform the transit time of minority carriers. The PN-junction body may be made by any known method.
