Title: Improvements in or relating to gas bearings
Inventor: LIVEY DAVID THOMAS
IPC: F16C32/06
Filed: 1968-02-10
Abstract: 1,263,054. Gas bearing. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 10 Feb., 1969 [10 Feb., 1968], No. 6686/68. Heading F2A. One member of a gas bearing comprises a unitary body of ceramic material part of which is porous, and part is non-porous. For journal bearings, the body is in the form of a cylindrical sleeve with the ends non-porous and the centre portion porous. The body may be made by placing in a die a combination of two ceramic matrices, one of which on sintering produces the non-porous portion of the body, and the other, the porous portion. The porosity of the material may be regulated by incorporating into the ceramic matrix an additive which is removed at a latter stage. The additive may be a volatile binder or a non-volatile carbonaceous material. If a synthetic fibre is used as the additive, the porosity can be controlled directionally. The carbonaceous additives may be removed by heating in an oxidizing atmosphere at 500- 600‹ C., and the body may subsequently be sintered at 1600-1800‹ C. An example describes the production of an alumina sleeve containing 0À25% by wt. magnesia, nylon being used as the additive.

Title: Process for the Production and Separation of Ammonium Sulphate and Glauber's Salt.
Inventor: DAWSON HARRY MEDFORTH
IPC: C01C1/24
Filed: 1917-05-12
Abstract: 114,236. Dawson, H. M. May 12, 1917. Ammonium sulphate; sodium sulphate.-Ammonium sulphate and sodium sulphate are obtained by the absorption of ammonia in a solution of nitre cake or other acid sodium sulphate in water or water and sulphuric acid, and separation of the salts by crystallizing out the sodium sulphate at a low temperature and the ammonium sulphate after concentration. The concentration of the solution after neutralization is adjusted if necessary so that the ratio of water molecules to the molecules of the mixed salts is approximately 1000: 70-80. The solution is then cooled to about 10 to 15‹ C., Glauber's salt separating out. The mother liquor is then concentrated at about 100‹ C. when ammonium sulphate crystallizes out till the molecular ratio of ammonium sulphate to sodium sulphate reaches 2.7. If further evaporated, the salt deposited contains sodium sulphate, but the impure salt is still adapted for use as a fertilizer. If the ratio of sodium sulphate to sulphuric acid in the original solution is relatively high, a more concentrated solution may be employed for absorption of ammonia, and in this case a part of the sodium sulphate is deposited in the anhydrous form. Sodium carbonate or ammonia liquor may be added to the liquor from the saturator to neutralize it before cooling. The mother liquor from the crystallization of ammonium sulphate is suitably diluted and mixed with a solution which is to be cooled for separation of Glauber's salt.

Patent GB-820082-A (GB)
Title: Tape transport system
IPC: G06K13/26
Filed: 1956-03-05
Abstract: 820,082. Driving sound film or tape. DEHN, S. G. (Consolidated Electrodynamics Corporation). March 5, 1956, No. 6919/56. Class 40 (2). [Also in Group XVI] Apparatus for controlling the drive of a record tape 10 comprises electrical switching 21 operated by the change of pressure in a vacuum chamber 12 occurring during the passage of an aperture 23 in the tape over an aperture 11 in said chamber 12. In the embodiment described with reference to Fig. 2, a tape 30 is drawn through an operational zone 32 by a capstan 34 or 38, according to the direction of travel, reversing of the drive being effected by the operation of a switch S or T tripped by the passage of tape apertures over vacuum chamber apertures. The circuit diagram of Fig. 2 shows the switch positions while in the OFF condition. Operation of a push-button control M F  produces a forward drive by establishing a circuit through forward relay F which operates contacts F 1 , F 2 , F 3 , F 4  and F 5  and thereby energizes take-up motor 45 and produces a drag in motor 42, and energizes solenoid 36 to press roller 35 against capstan 34, the relay F being locked on by the closure of contacts F 5 . When an aperture at the end of the tape reaches the aperture of a vacuum chamber controlling switch S, switch S is operated to open contact S 1  and close contact S 2  to operate reverse relay R and release forward relay F, respectively. Contacts R 1 , R 2 , R 3 , R 4  and R 5  are thereby operated to reverse the drive of the motors and energize solenoid 40 to press roller 39 against capstan 38, relay R being locked on by contact R 5 . The value of resistances 54, 56, 62 and 63 is so arranged that the trailing motor 42, 45, which ever one it might be at the moment, has a lower voltage applied to it than to the motor which is acting as the take-up motor. At the end of a reverse drive, forward drive is re-established by the operation of switch T tripped by the passage of another aperture in tape 30. The drive of the tape in either direction may be stopped by the operation of push-button switch M s  which interrupts the current supply and releases both relays F and R. A break in the tape accomplishes the same result by the simultaneous operation of switches S and T. Specification 817,997, [Group XVI], is referred to.

Title: Improvements in machines for filling cans with solids and liquids
Inventor: WOLSTENHOLME HAROLD
IPC: B65B1/48
Filed: 1956-03-07
Abstract: 812,383. Filling containers with solids and liquids. MATHER & PLATT Ltd. March 5, 1957 [March 7, 1956], No. 7116/56. Classes 94(1) and 125(2). In a machine for filling cans with solids and liquids in consecutive operations, a can 1, Fig. 1, which has received a charge of solids, such as peas or beans, is raised into engagement with the rubber sealing flange 2 of a liquidfilling head which moves with the can while delivering a charge of liquid such as brine or tomato sauce. There may be sixteen heads moving in a circular path. The can lifts the flange against the action of a spring 4, thus allowing the entry of liquid through a valve 3, and the solids in the can engage arms 9 on a rod 8 passing through a vent tube 5 and carrying a stopper 6 which normally prevents or restricts the passage of air through the tube. The rod and stopper are thus raised to vent the can, If the charge of solids is absent or incomplete the stopper remains in its lower position and, on movement of the head, a flange on the stopper engages an arm 10, Fig. 2, to cause rotation of a shaft 11 which is geared to a rotary cam 12 arranged adjacent a rotary member 15. The latter is driven in synchronism with the heads and carries sixteen displaceable pegs 16. If the cam is rotated, the peg corresponding to the head engaging the defective can is displaced to the right as it passes the cam, so that when it reaches its lowermost position it operates an arm 17 actuating a switch 18 carried by a plate 19. The switch controls an indicator or mechanism for rejecting the defective can, e.g. a plunger which displaces the can from its track through an opening in a guide rail. The peg is reset by a cam surface on the plate 19 and the arm 10 and associated parts are returned to their initial positions by a torsion spring 21 after the stopper has cleared the end of the arm.
