Abstract: 376,425. Fittings for loading and unloading vehicles ; conveyers. MOVABLE FLOOR (VEHICLES), Ltd. and RENWICK, A. E., Portfield House, Adelaide Street, Cardiff. May 18, 1931, Nos. 14678 and 21197. [Classes 78 (i) and 78 (iv).] Relates to vehicles provided with a movable floor for end or side loading formed by an endless or other band 5 mounted on or secured to drums 3, 4, the band being supported throughout its length by intermediate rollers. These rollers are arranged in parallel sets 14, 15, 16, the rollers of each set being staggered so as to facilitate removal for repair and to provide more continuous support for the band. Either of the drums 3, 4 may be operated by a removable handle through reducing-gear (Fig. 4, not shown) in boxes 6 .. 9, and the gear which is not in use may be thrown out of action by sliding the operating pinion axially with its shaft. A spring actuated pawl holds the pinion in the inoperative position. A similar pawl may engage one of the pinions of the gear-train to hold the band stationary in any position. The rollers 14, 15, 16 are mounted between longitudinals 1, 10, 11, 2 and consist of metal tubes running on ball bearings on fixed spindles 18. The spindles are secured in the longitudinals by nuts 21 and may be withdrawn through the inner member 24 of the ball bearings which make a sliding fit. The ends of the rollers are rounded. Specification 293,997, [Class 78 (iv), Loading &c.], is referred to.

Title: Overvoltage limiting circuit arrangement
IPC: H02H9/04
Filed: 1973-03-28
Abstract: 1420387 Overvoltage protective circuits SEMIKRON GES FUR GLEICHRICHTERBAU U ELEKTRONIK mbH 28 March 1973 [1 April 1972] 14854/73 Heading H2H [Also in Division H3] An overvoltage limiting circuit arrangement has two rectifier branches 2a, 2b each comprising one or more selenium rectifiers, the branches are connected in series opposition and a respective semi-conductor diode 4 is connected in parallel with each rectifier branch and each semiconductor diode 4 presents when its associated parallel rectifier branch is forwardly biased a lower impedance current path than does the parallel rectifier branch, so that the overvoltage is limited to a value near to the breakdown voltage of the rectifier branch which is reverse biased. The circuit provides overvoltage protection of a device such as a semi-conductor device connected in parallel to the arrangement and used in an A.C. circuit. When the rectifier section 2a conducts in the forward direction the voltage across this section is effectively short circuited to the lower voltage across the semiconductor diode 4 which may be a Si rectifier and the overvoltage across the device is limited by the voltage across the rectifier branch 2b which conducts in the reverse direction. The operation of the branches 2a, 2b reverses for the opposite polarity applied at 2. A construction of the circuit arrangement is disclosed (Fig. 3, not shown). A further embodiment is disclosed (Fig. 4, not shown) having three branches, each branch comprising a single selenium rectifier (2) and a parallel connected semi-conductor diode 4.

Abstract: 685,363. Automatic tension control systems. HOE & CO., Ltd., R. June 7, 1949 [June 4, 1948], No. 15170/48. Class 38 (iv). In a web tension control apparatus the degree of wrap of a retarding belt round the web-roll is determined by the web tension, and the motor controlling the application of the belt is supplied from an impulse generating network. As shown, Fig. 1, the web 4 is unrolled from roll 3 and its tension detected by floating roller 6 supported on arm 13 mounted to rock about centre 14. Arm 13 controls, through linkage 15, a switch 16, Fig. 2, which determines the direction of motion of motor 17. Roll 3 is retarded by the endless belt 7, which is driven by gearing 11 at a speed 2 per cent lower than the speed of web 4 and the extent of wrap of the belt round 3, and therefore the braking effect, is determined by the adjustment of arm 12 by the motor 17 about axis 18. The forward and reverse coils 24, 25 of the motor are energized respectively by closure of contacts 20, 21 of switch 16 and the supply is rendered intermittent by relay 30, the coil G1 of which is energized periodically from the impulsing network A. In the latter, the condenser C is alternately charged and discharged by the contact E moved by coil D connected across C; the contact H, in series with G1 is moved with E.

Abstract: 1,134,994. Change-speed gearing. DEERE & CO. 3 April, 1967 [4 April, 1966], No. 15180/67. Heading F2D. A vehicle transmission for agricultural or industrial tractors includes a planetary twospeed direct/reduced or direct/reverse gear in series with, and ahead of, a main change-speed gear, the input shaft 68 of the latter extending through a hollow shaft 50 of the planetary gear, which hollow shaft carries input pinions 52 for a power take-off (PTO) drive. The planetary gear comprises a reaction sun 92 which is held by a brake 88 for reverse ratio, an output sun 74 formed on the shaft 68, and rigidly connected planets 96, 94 in a carrier 34, meshing the suns 92, 74, respectively. Carrier 34 is splined to the hollow shaft 50 and secured to the input member 78 of a clutch 80 the output member of which is splined to the shaft 68. Clutch 80 is engaged for direct drive and brake 88 is engaged for reverse, both being hydraulically engaged and spring disengaged. A clutch 62 between a motor (not shown) and the input member 78 of clutch 80 is engaged for PTO drive. In addition, clutch 80 or brake 88 must be engaged for propulsion drive. A pinion 76 on shaft 68 meshes a gear-wheel 32 on a shaft 30 of the main gear-box. In a modification (Fig. 4, not shown) the relative sizes of the gear-wheels in the planetary gear are arranged to give a reduction ratio instead of reverse. A further modification (Fig. 5, not shown) has a common input member (132) to a clutch (134) which when engaged gives direct drive to the main gearbox and a clutch (136) which when engaged gives PTO drive, this arrangement allowing propulsive drive without engaging PTO drive.
