Title: Improvements in ionization chambers
IPC: H01J47/02
Filed: 1955-06-22
Abstract: 780,283. Ionization chambers. COMMISSARIAT A L'ENERGIE ATOMIQUE. June 22, 1955 [July 9, 1954], No. 18103/55. Class 39(1). The leakage resistance between the electrodes of an ionization chamber having one electrode arranged within the other is reduced by locating the voltage source inside the chamber and connecting one terminal to the inner electrode and the other to a conductor which passes through a wall of the chamber in insulated fashion and supports the voltage source. The chamber shown comprises a cylindrical envelope 1 of a synthetic resin, glass or other insulating material closed by end walls 7 and 8 and provided with an inner conductive coating 5 forming the outer electrode. Springs 6 fastened to the end wall 7 by screws 11 provide connections between the coating 5 and a metal member 10 screwed into a central opening in the wall 7. An insulating bush 3, preferably of polystyrene, is mounted in the member 10 and supports a screwed metal rod 17. A curved spring 20 is clamped between a nut 18, washer 19 and the bush 3 and makes contact with the insulated input member 21 of a pre-amplifier 22. The rod 17 extends beyond the bush 3 through a distance piece 23 and carries a battery 4. The negative terminal 24 of the battery 4 is connected to the rod 17 while the positive terminal 25 is connected through rods 26 and 27 to the apex 28 of a hollow second electrode 2 which surrounds the battery and extends as far as the negative terminal 24, but is spaced by an insulating ring 29.

Title: Improvements in or relating to multi-roll rolling mills
IPC: B21B13/14
Filed: 1960-05-23
Abstract: 919,987. Rolling. SVENSKA KULLAGERFABRIKEN A.B. May 23, 1960 [June 16, 1959], No. 18136/60. Class 83 (4). In a multi-roll rolling mill for rolling strip working rolls 11 are supported partly by fixed backing rolls 13 through intermediate rolls 12 and partly by an adjustable backing roll 15 either through direct contact or through one or two intermediate rolls 14 so that the working rolls may be adjusted relative to the fixed backing rolls 13. The bearing housings 16 for the fixed rolls 13 are bolted together by prestressed bolts 17, the housings themselves comprising either two or four sections with or without adjusting shims between. The rolls 14, 15 are carried in vertically displaceable bearing housings 19, 20 and the adjustment of the rolls 14, 15 is effected by screws 18 operated by handwheels through worms 21. In view of the angular relationship of the rolls 12 with the work roll plane the vertical displacement of the work rolls is less than the displacement of the roll 15 so that a very sensitive adjustment results which is limited only by the need for the rolls 12 to be retained by the rolls 11, 13. A set of backing rolls 13, 15 on one side of the rolling plane may be non-adjustable.

Title: Improved method of casting metal ingots and billets

Filed: 1938-06-18
Abstract: 516,231. Casting-machines. BIRMINGHAM ALUMINIUM CASTING (1903) CO., Ltd., and PRITCHARD, P. June 18, 1938, Nos. 18137 and 18138. [Class 83 (i)] Moulds.-In casting metal by gas pressure into a mould 14 placed directly over the heated pot 12, the metal is caused to flow through a nozzle 13 of such dimensions that it remains molten after the casting has set, the gas pressure being maintained until this occurs. The pot 12 is heated by gas or oil burners 18, and is connected to a reservoir 3 by a pipe 6 provided with a shut off valve 7, a valve 8, by which it can be exhausted, and a needle regulating valve 10. The reservoir 3 is filled with compressed air by a main 1, the pressure being indicated by a gauge 5 and regulated to desired value by an adjustable safety valve 4. When the pot is at the correct temperature air or other gas is admitted to cause the metal to flow into the mould slowly and thus avoid oxide inclusion. The speed is indicated by a manometer 11 and controlled by the valve 10. When the mould is full the metal seals an air vent in the top of the mould and the pressure in the pot rises to that in the ressrvoir 3. When the metal in the mould has set the pressure in the pot is relieved by closing the valve 7 and opening the valve 8 to exhaust. When the casting has two or more parts a, b', Fig. 3, joined by parts of smaller cross section the nozzle 13 broadens at its upper end into a corresponding number of channels 32, 33 which feed the molten metal direct to the larger sections. The mould 26 has core parts 28, 29 and is in two parts connected by hinges or fastenings 27.

Abstract: 1,101,992. Electric motors; control of stepping motors. PARRISH INSTRUMENTS Ltd. 29 April, 1964 [1 May, 1964], No. 18244/64. Headings H2A and H2J. [Also in Division G3] A multiphase stepping motor has a polarized rotor and stator windings supplied in sequence through transistor switches controlled in accordance with the value of the voltage internally generated in the stator winding not being externally supplied. The ends of windings W1, W2, W3 are connected to diodes d1, d2, d3, and transistor switches T1, T2, T3, the diodes having a polarity such that they do not conduct when current is supplied to the respective winding. As the rotor rotates, a voltage of opposite polarity to the applied voltage will be generated in the winding not connected to the supply and current will flow through the respective diode to provide a voltage A across resistor R. This voltage A is used to vary the output frequency of the oscillator controlling the transistor switches, thereby controlling the speed of the motor. In a servo system using the motor, a further gating unit may be provided which interrupts the output of the oscillator in response to a fall in the value of an error signal. The voltage A may be modified to provide different motor characteristics.

The lever 7 and catch 6 are pivoted on a pin 8 carried by a base plate 10 mounted on the panel 2 by means of screws passing through slots in the base plate to allow its position to be adjusted. When the door is moved to its closed position the catch 6 moves independently of the lever 7 to ride over the catch 4. A spring 17, which may be a coil spring, has one limb resting against the base plate 10 whilst the other presses the catch 6 against the catch 4 in the fastened position and against the shoulders 15 of the lever in the unfastened position. A second spring, shown as a hair-pin spring, keeps the corner 19 of the lever in contact with the base plate 10. The Provisional Specification describes a coil spring having three limbs which keeps the shoulders of the lever and catch pressed together both in the fastened and unfastened positions.

Boron trifluoride, silicon tetrafluoride, titanium tetrafluoride, arsenic trifluoride, potassium-boron fluoride, sodium silicofluoride, potassium-titanium fluoride and potassium-arsenic fluoride are specified.  The terms alcoholates, thioalcoholates, phenolates and thiophenolates are based on alcohols, thioalcohols, phenols and thiophenols in general and mentioned are cresolates, xylenolates and phenyl phenolates and their corresponding thio derivatives.  The esters obtained may be distilled off or extracted with solvents such as benzene, trichloroethylene or ether.
