Abstract: 669,740. Hay-loaders. WILDER, Ltd., J.Nov. 5, 1949 [Nov. 9, 1948 ; Sept. 7, 1949], Nos. 29068/48 and 23132/49. Class 6(iii) [Also in Group XXX] A loading appliance in which grass is elevated between two parallel runs of two endless belts has the under belt passing over an inverted L-shaped run, the upper arm of the L carrying the grass after elevation into the tipping or discharge position.. The hayloader of Fig. 6 comprises a chassis 1 mounted on ground wheels 2, the chassis supporting a main driving belt drum 3 grooved to receive an endless belt 4, a second endless belt 5 engaging the drum on each side of the groove and passing above the first belt. On the front of the chassis is a pick-up drum 6 with projecting tines picking up the grass as the drum revolves. From the drum 6 the grass is carried upwardly between the parallel runs of the two belts and after being elevated is carried forwardly by the under belt 4 to the tipping position, whence it falls into a truck towing the hay-loader. The drive to the beltdriving drum 3 and the pick-up drum 6 is by way of chain gearing and a lay shaft 14 from the shaft of the ground wheels 2. The drive-transmitting chain between the lay shaft and the driving shaft, may be tensioned by a vertically adjustable jockey sprocket or pulley. The pick-up drum 6 is adjustably mounted so that it can be raised to an inoperative position. Each end of the drum is rotatably mounted in a bracket on a skid 18 adapted to ride over the ground surface and maintain the drum at a constant distance from the ground during operation. The drum is in sections between which the tines 20 are mounted on rings. Fixed to each skid is a link 21 rotatably connected to the chassis, Fig. 4. A link 22 secured to each skid passes through a guide 23 on the chassis and has a pin-and-slot connection to an arm 24 extending from a control shaft 25 rocked by a handle 28 to raise or. lower the skid. The handle 28 can be held in position by a quadrant 29. An extensible draw-bar by which the loader is towed comprises a channel member 30 upon which an extension member 31 is slidable, being held in position by a catch or pawl 34 locked by a screwed clamp 34a, Fig. 7. Mounted on the chassis is a superstructure 37 supported by uprights 38 and having a horizontal extension 39 over which is a cowl 40. The upper belt 5 may consist of a plurality of endless strips 5a, pronged guiding bars carried by the chassis and superstructure projecting between the strips at intervals along the belt. The belt 5 may be driven by the pressure of the grass carried by the belt 4. Mounted on the skid frame is a deflector plate 41, which is slotted to form strips passing between the prongs on the pick-up drum 6.

Title: Improvements in or relating to electrical control systems
IPC: H02P7/34
Filed: 1928-10-13
Abstract: 321,300. Johnson, E. M., and Associated Electrical Industries, Ltd. Oct. 13, 1928. Systems depending on the use of two or more motors; controlling motors by varying terminal voltage.-In a system of control for two motors 15, 19 fed by variably excited generators 11, through switches 13, 17 for connecting separate motors to separate generators or both motors to either generator at will, means are provided for ensuring that both the motor field-windings 5, 7 are excited when both motors are receiving current from the same generator. This is effected by taking the circuit energizing the fieldwinding 9 or 10 of the active generator through contacts of two controllers 6, 8 which are associated respectively with the two motors 15, 19. If either controller is in its " off " position, where the corresponding motor field is dead, there is a break in the circuit of the generator field and consequently no current to the motors. The circuit passes through switches 37, 38 which may be interlocked or coupled with the switches 13, 17, as an additional safeguard. The controllers are arranged to connect the respective motor fields to line wires 23, 24 through groups of reversing contacts 25, 29; the controllers also vary resistance 34, 36 n the fields of the respective generators. When both motors are on one generator an additional current-limiting resistance is put in the generator field. In a slight modification the motors are reversed by reversing the generator fields. The single motors and generators may be replaced by groups of machines.

Abstract: 1,199,991. Data handling arrangements. INTERNATIONAL COMPUTERS Ltd. 26 June, 1968 [28 June, 1967], No. 29802/67. Headings G4A and G4C. A data handling arrangement comprises a first data storage means for storing a plurality of items of data, means for withdrawing items of data serially therefrom, second and third data storage means for feeding items of data into said first data storage means from either said second or third data storage means and control means for maintaining different numbers of items of data stored in said first data storage means in dependance on whether the last item was fed from the second or third data storage means. As shown (Fig. 1) the data storage means comprises a register 16 for storing instructions to be executed by a digital computer (not shown). Register 16 comprises a plurality of stages A-H each of which may store one instruction. Instructions are fed into register 16 at the top and retrieved by the computer from stage 16H, the contents of the register being shifted down as each instruction is removed. New instructions for the register 16 are accessed under control of units 20, 22 from a fast store 10 of small capacity if present therein or otherwise a slow store 12 of large capacity. The stores 10 and 12 which may comprise integrated circuits and magnetic cores respectively operate under control of a circuit 14 so as to tend to maintain frequently used instructions in store 10. A sensing and comparing unit 28 checks the contents of the register 16 and causes a further instruction to be fed thereto when the number of instructions therein falls below a selected predetermined level, the particular level selected depending on whether the last instruction originated from store 10 or 12 and being lower for store 10 than 12, the aim being to facilitate the processing of jump instructions. In a modified arrangement (Fig. 2, not shown) each register stage can store 4 instructions for retrieval by the computer in sequence and new instructions can be fed into any stage not necessarily the top one.

Abstract: 1,008,542. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Aug. 2, 1963 [Aug. 3, 1962], No. 29958/62. Heading H1K. Non-significant impurities are removed from the vicinity of a P-N junction in a semiconductor device by disturbing the arrangement of atoms in the crystal lattice in a region not coincident with the P-N junction and heating the device to a temperature at which the diffusion length of these non-significant impurities becomes equal to or greater than the distance of the P-N junction from the disturbed region. In the embodiment described, a slice of N-type silicon 1 is gallium doped to produce a P-N junction 2. The surface of the slice is then abraded with alumina in water on a glass plate to produce a disturbed region 3. The slice is then heated to 1100‹ C. in oxygen, at which temperature the diffusion length of the non- significant impurities is equal to or greater than the distance between the junction 2 and the region 3. The disturbed region may alternatively be produced by heating and rapidly cooling a localized region of the crystal by a high energy beam of particles or by electromagnetic radiation. Impurities in silicon, referred to as, being treated in this way, are copper, nickel silver, gold and iron and their removal from the vicinity of the junction results in a very great reduction in the magnitude of the reverse current.
