Patent GB-896665-A (GB)
Title: Improvements in or relating to hoppers for supplying material to weighing machines
IPC: G01G21/00
Filed: 1961-01-03
Abstract: 896,665. Hoppers for weighing machines. SIEGBURG, M. Jan. 3, 1961 [Jan. 5, 1960; July 1, 1960], No. 164/61. Class 78 (1). Material is fed to a weighing machine from a hopper 1. The discharge therefrom is controlled by pivoted flap 2. The discharge takes place between the hopper and wall 3, the flap 2 serving in the position shown to give a coarse adjustment discharge, and when rotated anti-clockwise to a second position to give a fine adjustment of discharge through hole 10 formed in flap 2 and when rotated anti-clockwise to a third position to shut-off discharge. The discharge therefore has a fine and equal adjustment. The inventive step lies in the provision of wall 3 which pivots about 11 and includes a counterweight 5 and an adjustment 4. The effect is that when the flap is adjusted to the fine weighing position the aperture 10 is kept open by the weight of material in hopper 1 which swings wall 3 anti-clockwise against the effect of weight 5. But when the material in the hopper is low, counterweight 5 swings wall 3 clockwise to close hole 10 and to stop the fine adjustment. Plate 6 is adjustable to vary the effects of the weight of the material in the hopper upon wall 3. Second embodiment, Fig. 10.-Hopper 101 is likewise controlled by pivoted flap 103 having a hole 104 within for fine adjustment. The hole 104 is controlled by piston 106 operated by load plate 114 pivoted at 113. In the coarse weighing position flap 103 opens normally to permit discharge. In the fine weighing position flap 103 is closed and piston 106 is normally raised by the pressure of material upon plate 114 to permit fine weighing discharge through hole 10. Should however there be an insufficiency of material in hopper 101, plate 114 rises to cause piston 106 to descend and to stop the fine weighing discharge. Alternatively the position of piston 106 may be operated by a level indicator positioned in the hopper.

Abstract: 605,674. Operating clutches. BURGESS, Ltd., F. H., and WOOLFENDEN, J. H. Jan. 3, 1946, No. 231. [Class 80 (ii)] [Also in Group I] A remote control means for operating clutches 11, 12 at opposite sides of an agricultural machine comprises an actuating lever 24 pivoted at the rear end of a centrally-disposed draw-bar 21 and movable by a cord or link actuated by the driver of the tractor. The lever 24 has a pair of oppositely-extending arms 23 connected by links 25 to levers 15 pivoted on brackets 19 secured to opposite sides of the machine, these levers 15 each having one of their arms formed as a fork for engaging a movable spring-loaded member 11, 12 of a clutch. The invention is shown applied to a manure distributer. The clutches are operated by a lever 27 and link 26 mounted on the draw-bar 21. The lever 27 has a ratchet and trigger-operated pawl so that the clutches will remain in the released position until the pawl is withdrawn from the ratchet, the clutches being engaged on release by their own spring pressure. In between the actuating lever 24 and lever 27 a device as described in Specification 594,981 is incorporated.

A., 32, Score Lane, Broadgreen, Liverpool. Jan. 4, 1935, No. 357. [Class 40 (i)] In a system for transmitting to a distance indications of the values of quantities such as current, voltage, power &c., the values transmitted are represented by the degree of modulation of a carrier current and automatic volume control apparatus is incorporated so as to render the transmission independent of disturbances affecting the carrier wave. As shown, the voltage of the bus-bars BB, which is to be indicated at a distance, is applied directly to the modulating valve MR of a carrier frequency generator OR which is associated with the line wires L<1> L<2> through transformer T<1>. At the receiver, the amplifier DR supplies a voltmeter through a rectifying bridge BR. Alternatively, the carrier may be suppressed and one or both side bands utilized. A plurality of different quantities may be transmitted simultaneously over the same line wires by employing different carrier frequencies or successively modulating the same carrier ; furthermore, one quantity may be represented by the phase of the modulation whilst another is represented by the degree of modulation. In order to render the receiving equipment independent of line conditions, automatic volume control comprising feed-back transformer T4, rectifier R and condenser C, is employed. Automatic volume control may be provided at the transmitter in addition to or as an alternative to that at the receiver.

Abstract: 1464821 Control rod drives WESTING- HOUSE ELECTRIC CORP 6 Jan 1975 [18 Jan 1974] 378/75 Heading G6C In a nuclear reactor control rod drive apparatus utilizing at least a pair of axially spaced grippers actuated by electro-magnet coils to move the rod in a step-by-step manner, and utilizing locking means for preventing disengagement of at least one of the grippers on interruption of electric power to the coils, the locking means is a mechanical member associated with an electro-magnet and requiring energization of the same for movement into and out of its locking position. In the embodiment the step-bystep raising and lowering of control rod drive shaft 50 is effected by sequential energization and de-energization of coils 21, 31 and 41 in a predetermined manner, in association with latch arms 32, 44 as described. Additional magnet coil 61 actuates a plunger carrying a pin (66, Figs. 2, 3 not shown), to co-operate, when coil 61 is energized, with latch arms to prevent any further axial motion of the control rod, and should power interruption ensue the arrangement is such that the control rod does not move. Coil 61 is of such ampere-turns as not to actuate the plunger if the voltage applied to coils 21, 31, 41 is inadvertently applied to it.

Sintered polytetrafluoroethylene films are made by pouring fine polytetrafluoroethylene powder combined with a lubricant on to a sheet, passing the sheet through compression rollers so as to form a thin and uniform film of lubricant - containing polytetrafluoroethylene, removing the lubricant, sintering and separating the sintered polytetrafluoroethylene film from the sheet. Sintering is preferably effected at a temperature of at least 327 ‹ C. Specified lubricants include solvent naphtha, white oil, toluene, solutions of polyisobutylene in these solvents, and alcohols and esters. Suitably, 10-30 g. of lubricant is mixed with 100 g. of the polytetrafluoroethylene powder. Mixing the powder and lubricant may be effected in a rotating or tumbling vessel. The sheet may be of metal, plastic, paper or fabric, heat-resistant materials being preferred, e.g. stainless steel, aluminium, polyimide resin, polybenzimidazol resin, glass-fibre cloth, carbonized fibre cloth and polyimide resin-coated fabric. The compression rolling causes the formation of a fibrous structure in the polytetrafluoroethylene, orientated in the machine direction. Lubricant is removed by heating or by solvent extraction and the film and sheet are then heated to sinter the polytetrafluoroethylene film, which may then be peeled off the sheet. As shown, the lubricant - containing polytetrafluoroethylene powder 2 is poured on to a sheet 3, and passed through compression rollers 1, 1. Lubricant is removed by passing the sheet through the drying oven 5 and sintering is effected in sintering oven 6. The film 7 is then separated from the sheet 3.
