Title: Improvements in and relating to gun turrets
IPC: F41A27/20
Filed: 1944-11-21
Abstract: 588,267. Gun turrets. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. Nov. 21, 1944, No. 23108. [Class 92 (i)] Relates to gun turrets in which the direction and rate of movement of the gun or guns is determined by the displacement of a control handle from a neutral position. According to the invention, the ratio of the rate of operation of the guns and turret to the displacement of the handle is variable either manually or by means actuated by the setting of the rangefinder so that it can be increased for targets at close range and decreased for dealing with more distant targets. In the construction shown, where the hydraulic training motor. 7 is driven by the output of a hydraulic pump 6 whose eccentric ring 5 is controlled by a handle 1, the link 3 is between the handle and ring 5 is adjustable in a slot 4 of the handle to vary the aforesaid ratio. The link may be moved in the slot at will by the pilot or it may be coupled directly to a range-finder of the kind in which a member is displaced'mechanically to indicate the range. In a modification a similar pin- and-slot connection is used between the control handle and the movable element of a throttle valve used in a hydraulically operated turret, and in another modification a similar arrangement is used to connect the handle to the sliding contact of an electrically driven, potentiometer-controlled turret. In a further modification, Fig. 2 (not shown), the variation in ratio is produced by controlling the speed of the electric motor driving the pump 6. This is effected by moving a sliding contact over a rheostat in series with the field winding of the motor.

Title: Process of recovering nickel from salt solutions
IPC: C22B23/00
Filed: 1956-07-26
Abstract: Nickel is recovered from a solution containing one or several nickel salts by first adding ammonia to the salt solution, preferably in amount at least 4 moles of ammonia to each mole of nickel, then reacting the solution with alkali amalgam to recover nickel as a nickel amalgam.  The cold nickel amalgam so formed may then be introduced in batches into an inert atmosphere in a low-temperature distillation vessel heated to 400-600 DEG C. to obtain mercury-free nickel in the form of globules, part of which may be removed and cooled in a non-oxidizing medium, the remainder being left to be built up during distillation of a further batch of amalgam.  Ammonia may be recovered from the spent salt solution by addition of lime or alkalies and used to render further salt solution ammoniacal.

Abstract: 687,176. Packeting-machines; baling-presses. WHEATLEY & SONS, Ltd., H. Sept. 17, 1951 [Sept 23, 1950], No. 23354/50. Class 94(i) In apparatus for compressing loose fibrous material and introducing it into bags, the material is conveyed by an air current along conduits a and b into a hopper c having perforated walls and falls into the path of a reciprocating ram d which forces it into a compression chamber h having a delivery end over which a bag n may be passed. The chamber is fitted with spring-loaded arcuate doors i at the entrance end and with spring-loaded doors j at the delivery end, the loading of the adjustable springs j<SP>1</SP> determining the degree of compression of the material at which the doors open to allow the material to be ejected into the bag. The ram d carries ramps d<SP>1</SP>-d<SP>4</SP> arranged to operate switches d<SP>5</SP> and m in the circuit of a reversible electric motor g which operates the ram through a winch f and cable e. During the compression of the material, the switch d5 is operative and the stroke of the ram is determined by the distance between the ramps d<SP>1</SP> and d<SP>2</SP>. The opening of the doors j closes a switch k which renders the switch d<SP>5</SP> inoperative and the switch m operative, whereby the stroke of the ram is lengthened to the distance between the ramps d<SP>3</SP> and d<SP>4</SP> to eject the material into the bag and force the bag off the end of the chamber. The bag is supported on a wheeled trolley p having an upstanding wall p<SP>1</SP> engaging the bottom of the bag. An adjustable stop, not shown, is provided to arrest the movement of the trolley before the ram has completed its stroke so that the material is subjected to a final compression in the bag. The engagement of the ramp d<SP>4</SP> with the switch m opens the switch and causes operation of a relay to return the motor to the control of the switch d<SP>5</SP>. To prevent blocking of the conduit b due to accumulation of material in the hopper, the latter is fitted with a roller s arranged below a deflector w and driven through a friction clutch s<SP>1</SP> by a motor s<SP>2</SP>. The roller controls a switch s<SP>3</SP> which, if the roller is arrested by the accumulation of material, reverses. the direction of rotation of an electric motor t driving a disc t<SP>2</SP> carrying a pin u which engages 'one or other of two fingers u<SP>1</SP>, u<SP>2</SP> on a slidable bar u<SP>3</SP> coupled to a lever v operating a valve v<SP>1</SP>. The latter is, therefore, moved from its normal position, in which the conduits a and b are in communication, to the dotted line position in which the conduit b is shut off and a relief conduit v<SP>2</SP> is opened to allow discharge of surplus material. The hopper is also fitted with a pivoted lever y which rises and falls as the ram reciprocates to prevent consolidation of the material in the lower part of the hopper.

Abstract: 503,063. Looms with automatic weft replenishment. CROMPTON & KNOWLES LOOM WORKS. Aug. 9, 1938, No. 23441. Convention date, Sept. 30, 1937. [Class 142 (iii)] Pneumatic weft-end holder arrangements. The 'weft ends W from the magazine Mare dropped by the weaver between the flared wings 80 of a guide furnished with a trough leading to a tube 71 which is notched at its upper end and communicates by means of a rubber tube 62 with a weft-end accumulator A. This is connected by a rubber tube 52 with a pump 41 whereby an intermittent suction is produced and the weft ends are drawn around the curved internal bore of the tube 62' which provies a friction surface for holding the weft end of the transferred bobbin during the transfer. Afterwards this weft end which extends into the shed is engaged by a' hook 90 on the lay and as this advances by a second smooth hook 91 on the loom frame. After being cut by the trample cutter, the weft end is sucked into the accumulator, which has a screen guarding the exit to the pump, and may have a hinged cover 57 with a soft rubber cushion forming an air-tight seal. The pump piston may be reciprocated by connections with the lay, so as to produce a vacuum when this moves rearwardly and picking occurs. The piston has a part closed by a valve, whilst flexible valve closes the outlet to the tube 52 to prevent air being blown therein. A rocking two-compartment magazine may be used, the weft ends extend. ing from the bobbin being thereby moved at the entrance to the thread holder. The inrushing air is thus enabled to distribute the weft ends uniformly. The loom has drop boxes at the other side. The tube 62 may have a grounded metal sheath 73 for conducting away induced static electrical charges. An accumulator of transparent material is mentioned.
