Title: Improved press
IPC: A01J25/15
Filed: 1963-05-16
Abstract: 979,168. Press for cheese curd &c. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. May 16, 1963 [May 17, 1962], No. 19533/63. Heading A2B. A press, suitable particularly for compacting grains of cheese curd, comprises an inner press chamber of rectilinear transverse cross-section, and an outer shell of curvilinear cross-section, a piston slidable within the press chamber, provision for applying fluid under pressure to the back of the piston and so cause it to advance into the press chamber and for applying the pressure of that fluid also internally also to the walls of the press chamber internally to the walls of the press chamber at the rear of the piston, and means to apply fluid under pressure to the space between the inner press chamber and the outer shell. The apparatus of Figs. 1 and 2 comprises an exterior cylindrical shell 1 in which is mounted a double-walled, rectangular prismatic, compression chamber 6 having a watertight skin 7 and a perforated inner sleeve 8. A piston 15, which is a close fit in the sleeve 8, is mounted on an extensible rubber tube 16. On opening the door 2, cheddared, milled and salted curd is charged into the sleeve 8, door 2 is closed, and the chamber 6 and the spaces 29, 30 and 31 are evacuated to 20-25 inch mercury vacuum. Water at atmospheric pressure is admitted to the tube 16 to move the piston 15 forward, consolidate the curd and expel air and whey through the perforations in the sleeve 8. The whey and air are removed in a vacuum pipe 27, the whey being retained in a trap 24. Further advance of the piston 15 builds up pressure in the curd, and, at the same time, pressure of water in the tube 16 reacting on the walls of the chamber is transmitted through gussets 10, 11, 12 and 13 to the outer shell 1 and the inside surfaces of doors 2 and 3. When the pressure in the curd reaches atmospheric, water at atmospheric pressure is admitted to spaces 29, 30 and 31. The pressure of the water is gradually increased, causing the piston 15 to advance further and compress the curd, expelled whey being evacuated by the pipe 27, which remains under 20-25 inch mercury vacuum. The water pressure is increased to 50 p.s.i.g. and maintained for 30 minutes. On concluding such compression of the curd, the water pressure is reduced to atmospheric, the vacuum source disconnected and the door 2 opened for discharge of the compressed curd.

Title: Improvements in telegraph systems
IPC: H04L25/49
Filed: 1919-08-11
Abstract: 142,375. Western Electric Co., (Western Electric Co.). Aug. 11, 1919. Duplex telegraphs; transmitting systems and apparatus; type-printing telegraphs.-In a telegraph system employing currents of opposite polarities, a wandering zero is prevented by grounding the line between successive impulses of opposite polarity and by supplying a positive current to the line between successive negative impulses and vice versa. A rotary distributor is employed provided with a resistance placed between the earthing segments and earth to prevent sparking and to maintain the balance in a duplex system. Construction. The movable contacts 1 - - 5 of a tape transmitter A are connected to the contact-segments 11 - - 15 of a rotary distributor D and to the operating coils of polarized relays 21 - - 25 by leads 6 - - 10 respectively. The circuits of the relays 21 - - 25 contain one winding of relays 26 - - 30. The relays 26 - - 30 are each provided with a second winding connected to the succeeding contact of the transmitter A. The armatures of the relays 26 - - 30 normally connect the contactsegments 36 - - 40 to earth through a lead 20 and resistance 31. The distributor D comprises a ring 17, connected to line 18, and a brush 16. Operation. If for a particular position of the tape the contacts 1 and 2 of the transmitter A be not operated, the relays 21 and 22 and the left-hand windings of the relays 26 and 27 are energized with negative current and the righthand winding of the relay 26 is energized with negative current thereby causing its armature to engage its front contact. The energization of the relay 21 by negative current causes this relay to connect the front contact of the relay 26 to a source of positive current which is connected to the contact-segment 36 by the operation of the relay 26, thereby sending a positive impulse c, Fig. 2, to line 18 between the two negative impulses a and b. If the contact 2 of the transmitter A be operated to connect the segment 12 to a source of positive current, the right-hand winding of the relay 26 is energized by positive current and its left-hand winding the negative current. Under these conditions, the armature of the relay 26 is not operated and the line 18 is earthed through the contact-segment 36 between the negative impulse d, Fig. 2, and the succeeding positive impulse e. If the brush 16 is wide enough to bridge the contact segments 11 - - 15 and the earthed segments 36 - - 40 the resistance 31 prevents sparking at the brush 16.

Title: Improved method of dressing or concentrating carbonaceous slimes and the like
IPC: B03D1/26
Filed: 1922-07-18
Abstract: 183,463. CoppÚe et Cie, E. July 19, 1921, [Convention date]. No Patent granted (Sealing fee not paid). F l o t a t i o n processes . and apparatus. - Apparatus for concentrating carbonaceous slimes, coal dust, and the like comprises a mixer 2 supplied with a weak current of water, oil, and air for emulsifying the material, which is delivered by the pipe 1. Compressed air injected from the tubes 4 produces ascending currents inside and descending currents outside the cylindrical bodies 5 to mix up the mass, which is also rotated by compressed air issuing from the inclined tubes 15. The emulsified mass passes through the overflow 6 into the separator 7, which is divided into a number of tapezoidal compartments 8 by the partitions 9 extending from a short distance below the level of the liquid, which is kept constant by a swans' neck outlet pipe 14. Air bubbles issuing from the air-atomizers 10 carry the carbonaceous particles to the surface of the liquid from which they are removed by scrapers 11 into channel 12. The schists and the insufficiently attached particles pass through the constricted openings below the partitions 9 into the next compartment 8, where the process is repeated. The schists are finally discharged from the bottom of the last compartment by the swan's neck outlet pipe 14.

Abstract: 484,177. Oil-gas generation. GAULT, H. July 16, 1936, No. 19746. Void. Convention date, July 17, 1935. [Class 55 (ii)] [Also in Group XI] A combustible mixture of gases and vapours is obtained by the partial flameless combustion of liquid-fuel with air in a granulated refractory mass, the fuel being poured directly upon the mass. A tube of 30 mms. diameter and 500 mms. length is packed for a length of about 350 mms. with silieo-aluminous material in grams of 5 to 7 mms. diameter. A limited volume of air is passed into the free space in the tube and some ccs. of fuel-oil or gas-oil. preheated to about 60‹ C., arc allowed to flow on to the refractory material and are ignited by an electrically-heated spiral in the free space. The heating current is then cut off and, after one or two minutes, the flow of oil is regulated to 1 cc. per minute and the air, which is at a pressure of 30 to 40 cms. of water, to the rate of about 15 litres per minute ; the flame is extinguished and flameless combustion ensues. The feed of fuel is then increased to 10 ccs. per minute to produce a combustible mixture. With fuels such as tars and refractory materials such as pumice stone, catalytic materials such as metals or reducible metallic oxides are preferably deposited upon the refractory material.

Patent GB-461411-A (GB)
Title: Production of fish meal and oil
IPC: C05F1/00
Filed: 1935-05-10
Abstract: <PICT:0461411/III/1> Oil is extracted from fish and marine animal material by accumulating the unpulped material in a vessel, treating it with a preservative which is volatile at temperatures low enough to be non-destructive to the material, removing substantially all of the uncombined preservative from the material by heating, and while the material is still warm applying more heat to digest it, and finally separating solid from liquid constituents.  Suitable preservatives are formaldehyde and acetaldehyde or their aqueous solutions, and chlorine.  Raw fish material is loaded on to a conveyer 3 and charged into a bin 1, being treated in transit, if desired, by one or more volatile liquid preservatives from a tank 7 by means of a spray 9.  Water from a tank 5 may also be added. Whether preservative has already been added or not, it may be supplied in gaseous form from a tank 8 via a diffusing outlet 12. The material in the bin 1, after accumulating for a period, is transferred into a cooker 14 where it is first heated to drive off the preservative which collects in a tank 17 and is then, without cooling, given additional heat to digest it.  The digested material is transferred to a press 19, the liquid constituents thereof passing to a drip pan 20, and from thence to an oil-settling basin 23. Instead of the pressing step, the digestion step may be employed in the cooker long enough to complete digestion and to evaporate all the water, thereafter the oil being extracted by means of a solvent such as gasoline and naphtha.  When employing formaldehyde or acetaldehyde as the preservative the material to be treated is preferably rendered neutral or slightly acid, for example by the addition of sulphuric, hydrochloric or nitric acid.  Specifications 9773/01, [Class 91], 286,709, [Class 49], 378,399, and 461,343 are referred to.

Abstract: 147,932. Schwalbenberg, P. J. May 19, 1916, [Convention date]. Thermostats.-The admission of cooling-air at the front of an engine radiator is controlled jointly by a thermostat in the water circuit and by a piston in a cylinder connected with the intake of the engine and subject to suction while the en. gine is working, so that air is admitted when the engine has been running sufficiently to warm the water to the temperature to which the thermostat is set, while the front of the radiator is closed when the temperature of the water falls or when the engine stops. In the arrangement shown, the front of the radiator is provided with a series of slats 8 pivoted at 9 to the frame and at their rear edges to a bar 14, one of the slats having a lug 10 connected to a controlling-bar 11. The thermostat 4 is located in a chamber 5 in communication with the pipe 6 conveying the warm water to the radiator, and the cylinder 3 communicates through a pipe 2 with the engine intake. When the temperature rises, a member 16 pivoted to the piston 17 in the cylinder 3 and resting upon the stem 15 of the thermostat, is adapted to rock a bell-crank lever 12 and pull the controlling-bar 11 against the action of a spring 19 to open the slats. When the temperature falls, the member 16 drops away from the lever 12, and when the suction ceases in the cylinder 3 a spring 18 moves the piston and the member 16 to the left, as shown in dotted lines.
