Title: Improvements in or relating to process for resolving dl-glutamic acid
Filed: 1955-11-15
Abstract: A process for resolving DL-glutamic acid comprises crystallizing solids from a solution supersaturated with respect to DL-glutamic acid at a pH of not more than 3.3 and containing seed crystals of glutamic acid in one of its optically active forms.  Alternatively, a solution supersaturated with respect to DL-glutamic acid hydrochloride at a pH of less than 1.0 is resolved by seeding with an optically active form of glutamic acid hydrochloride.  Preferably at least 5 per cent and more preferably 25-50 per cent by weight of seed crystals based on the weight of racemate are added to the supersaturated solution.  The seed crystals are preferably added to a supersaturated solution maintained at a temperature of 20-30 DEG  C., the crystallization of solids being completed within 1 to 60 minutes from the addition. The supersaturated solutions are prepared by (1) slurrying DL-glutamic acid monohydrate with water, adding an alkali or inorganic acid to form a solution and adjusting the pH with an inorganic acid or alkali respectively; (2) by dissolving DL-monosodium glutamate dihydrate in water and adjusting the pH with an inorganic acid; (3) by dissolving DL-glutamic acid hydrochloride in water or DL-glutamic acid monohydrate in dilute hydrochloric acid and adding concentrated hydrochloric acid to either solution until the HCl content is at least 20 per cent by weight.

Abstract: 211,959. Smith, H. J. Nov. 29, 1922. No Patent granted (Scaling fee not paid). Fluid - actuated valves for refrigerating systems. - The flow of refrigerant from the expansion coil to the compressor and the flow of cooling-water to the jacket are controlled by means which in turn are under the dual control of the temperature and delivery pressure of the compressor. The means comprise bellows 28, Fig. 2, fixed at one end to a plate 27 rigidly secured by bolts 26 to the casing C, and, at the other end, to a diaphragm 29 secured to a cross-bar 25. Bolts and spacing members 24 secure a cross-bar 23 to the bar 25, and this bar is provided with a central aperture 23<a> forming shoulders coacting with a plate 22<a> on a valve stem 22. One valve is arranged in the pipe 7 leading from the expansion coil at the junction of this pipe with another pipe 8 leading to the inlet of the compressor, and another valve is arranged in the pipe line 13, 14 feeding water to the compressor cooling jacket. This supply is arranged as a by-pass for the water coming from the condenser, Fig. 1; a pressure-relief valve 12 opening when valve 22 in the compressor cooling-water supply is closed, permitting escape of the water from the condenser. The casing C, Fig. 2, in which the valves are housed, forms part of the delivery space of the compressor and contains the sealing oil surrounding the valves, an oil separator S and an outlet N to the condenser. Refrigerant is confined within the bellows 28 to comprise the temperature-sensitive element. The back pressure from the condenser, acting on the diaphragm 29, closes the valve 22 if the refrigerant in the bellows is liquid and keeps it closed until after the compressor has run for a time sufficient to heat up the sealing oil to cause the refrigerant to vaporize with consequent opening of the valves.

Title: Improvements in or relating to methods of producing malleable bodies of metallic beryllium
Inventor: DODDS HARRY WILLIAM
IPC: C22C1/04
Filed: 1957-10-21
Abstract: 842,226. Powder metallurgy. BRUSH BERYLLIUM CO. Oct. 21, 1957, No. 32845/57. Class 82(1) Malleable bodies are made from beryllium by charging the powdered metal into a container or die (13), subjecting the interior of the container and the beryllium to a preliminary evacuation and heating at a temperature below sintering temperature until a large part of any gas or vapour sorbed in the powder has been removed, .then subjecting the interior of the container and the beryllium to a prolonged combined evacuation of gases and heating at a higher temperature ranging from that at which sintering begins upwards to a temperature below that at which pronounced grain growth of the beryllium would occur, until the beryllium is sintered throughout, and simultaneously applying mechanical pressure (at 17). A suitable vacuum is 10 microns or less of mercury; suitable temperatures are 900‹C (preliminary) and 1000‹ to 1125‹C for sintering; the mechanical pressure may be only 68-70 1b./sq. inch. Purified beryllium powder is carefully weighed and according to the density (say 1.85) required for a body of known volume, placed in a removable stainless steel liner in container 13, and the vacuum pump is connected at 12 to reduce the interior pressure to 10 microns or less the plunger 16 being lowered in the position shown. The furnace heated by burners 5 then heats the berlyllium &c. to 900‹C, the vacuum pump still acting. Plunger 16, is then depressed to exert a moderate pressure of some 68-70 1b./sq. inch upon the beryllium and simultaneously the heating is increased to between 1000‹C and 1125‹C to sinter it, the pump still evacuating at 12. When the volume indicator gauge 28 shows the computed volume to have been attained, the heating is cut off and the plunger raised. When cool, the furnace is opened, the liner 15 removed and the liner peeled from the body. Fig. 2 shows stainless steel die parts 33, 34 as used in making a beryllium spur gear wheel.

Patent GB-733375-A (GB)
Title: Apparatus for removing slabs from a stack and converting them to smaller pieces
IPC: A23G3/02
Filed: 1952-12-29
Abstract: 733,375. Feeding gum slabs. WRIGLEY, Jr., CO., W. Dec. 29, 1952 [Feb. 8, 1952], No. 32885/52. Class 117. Apparatus for feeding gum slabs 97 from hopper 30 comprises an ejection ram 31 which reciprocates in a curved path. As shown (Fig. 9) the ram 31 is driven from reciprocating hub 61 so that it swings in parallel fashion about pivots 50, 51, being connected thereto by arms 49, 48 and moves the lowermost slab 97 from the hopper on to endless conveyor 85, by which it is fed to slow rolls 33. Said slow rolls 33 feed it to fast rolls 34 so that the latter divide the slab into portions and feed them to a stack (not shown), the height of which is controlled by a photo-electric cell so that the feed stops when the height is too great. As the ram 31 returns it operates levers (not shown) whereby the bottom of the inclined hopper is shaken to urge the next slab to drop into place for discharge. The ram, conveyer and slow rolls are driven synchronously from one or other side of clutch 36. The ram derives its reciprocating movement from shaft 84 (Figs. 10, 11) through cam follower 80 which engages cam 83 on shaft 84, so that shaft 74 is caused to oscillate and to drive vertical shaft 66 to oscillate the ram, the drive passing through clutch 70-68 (not shown). The parts of the latter clutch are connected by spring-pressed rod 72 so that should a gum slab jam in the ram the relative movement of the two will cause rod 72 to move out to operate switch 73 to stop the motor. The endless conveyer 85 and slow rolls 33 derive their drive from shaft 84 which in turn is driven from gear 113 through the special clutch 36 designed to stop the said conveyer at positions such that the slabs cannot be chewed up by the fast rolls. Clutch 36 has the driving ring 131 furnished with internal recesses 132, a control ring 138 furnished with corresponding recesses 143 and external lugs 139, and the driven member 149 furnished with sliding block 155 which normally engages and connects the recesses 132 and 143 so as to transmit the drive from gear 113 to shaft 184, the control ring rotating idly. When however too many slabs fall on to the stack, the photoelectric cell operates to lower detent 142 to engage and stop the rotation of the control ring: the continued rotation of the driven member causes the withdrawal of block 155 from engagement with the recesses 131 of the driving ring so that the driven member stops and the conveyer in turn stops. A projection 152 formed on driven member 149 moves in slot 146 formed in control ring 138 to allow relative movement between driven member and control ring. An additional control to shaft 84 is fitted in the shape of brake 185 (Fig. 10) which brake is a cam-shaped element freely mounted to turn on shaft 74 so as to engage the rim of cam 83 secured to shaft 84 and thus to prevent the rotation of said shaft 84 in the wrong direction, which direction produces jamming.

A disc-shaped workpiece 10, Fig. 4, having a web 11 and a rim 12, is upset by filling the recess between the rim and web with a solid malleable filler 18 which is more easily deformable than the workpiece, heating the workpiece and filler and then upsetting to reduce its thickness and increase its diameter, Fig. 5. The workpiece 10 may be of titanium alloy, nickel-molybdenum steel, or stainless steel. If the forging is performed at 1930‹ F. the filler is of grey iron and if at 2000-2300‹ F. the filler is of mild steel. Filler discs 18, 20 are placed in opposite recesses of the workpiece, after providing an intermediate coating of graphite to prevent seizing, and are secured by spot welding. After heating, the workpiece is upset by steady pressure or by hammer blows between dies 24, 25 to form the disc 10<SP>1</SP>. Any flash 27 is then removed. The disc may be further enlarged in diameter by rolling and thereafter the filler 18<SP>1</SP>, 20<SP>1</SP> is detached by high-pressure liquid applied to the interfaces through drillings in the filler, Fig. 6 (not shown). Finally the rim only may be further upset between dies 44, 45, Fig. 7 (not shown).

Abstract: 669,035. Multiplex pulse signalling. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 17, 1947 [Oct. 20, 1939], No. 33315/47. Class 40 (v). In a television system in which the sound signals are transmitted in the form of a single short pulse following each line synchronizing signal, the sound receiver is active only at the times of receipt of the pulses. At the transmitter, the sound signal from source 1, Fig. 2, is fed to a cathode follower stage 2 feeding valve 5 through diode 3. Pulses from source 4 are applied to the anode of diode 3 and the resulting amplitude modulated pulses from valve 5 are mixed with the vision signals from source 6 and synchronizing pulses from source 8, for application to the radio transmitter 10, 11. The detected pulses from the receiver 12 are fed to a circuit 16, from which sync. pulses B, Fig. 3, are obtained, and applied to the grid of valve 20 to discharge condenser 21 in the cathode circuit of valve 19, point E of graph D. A delayed sync. pulse from lead 15 gates open the amplifier 14 feeding the sound pulses to valve 19. The condenser 21 is thereupon charged to a potential F proportional to the pulse amplitude which only slowly falls until the next discharge pulse arrives at point G. The resulting voltage across the condenser is filtered at 23 and applied as graph H to the audio amplifier 24.
