Title: Press for compressing and extruding a product particularly an animal feeding-stuff
IPC: B30B11/00
Filed: 1977-02-16
Abstract: 1526703 Regulating roller and ring extruder drive SOC D'APPROVISIONNEMENTS DES INDUSTRIES ROUTIERES ET PETROLIERES 16 Feb 1977 [20 Feb 1976] 06502/77 Heading B5A A roller and ring extrusion press, for compressing and extruding animal feedstuff, is driven from a motor 8, via a clutch 16, and a torque converter 17 whose output speed is maintained above that yielding a predetermined ratio of torque transmission from the motor 8, e.g. at not below 0À72 efficiency, by a tachometer 20 which measures the output speed of the torque converter 17 and transmits a signal to a means regulating the feed of feedstuff to the press and acting, when the output speed falls below a predetermined value, to decrease the rate of feed to the press and thereby increase the output speed above the predetermined value. The rate of feed may be regulated by a screw whose speed of rotation is varied to effect the regulation or, as described, by a pivoted flap 4 which acts by varying the degree of obturation of a feed chute 3 to the press, and which is driven by a hydraulic actuator 21 which is controlled by a servo-valve 22, actuated from the tachometer 20 by an amplifier in which is set the predetermined value of the output speed, and which is also connected to effect disconnection of the clutch 16 if the output speed drops substantially below the predetermined value, i.e. due to jamming of the extrusion die by a foreign body. The amplifier may also be used to control the addition of steam to the foodstuff. The press comprises an annular die 1 being radially directed channels 2 through which the extrusion is effected by co-operation of the die with rollers 6 which are freely rotatable about axes 6 carried by a shaft 10.  The output from the converter acts either to rotate rollers 6 around the die interior, with the die being fixed against rotation or, as shown, acts to rotate the die 13, via gears 15, 14 with a shaft 10, on which the rollers 6 are carried, being fixed against rotation at a shear pin connection 11 to the press casing.

Title: Improved process for removing hydrogen sulphide from gases
IPC: B01D53/52
Filed: 1923-03-08
Abstract: In a process for absorbing sulphuretted hydrogen from gases by means of a solution of an alkali or a suspension of an alkaline earth and regenerating the absorbent liquor by means of a gas containing carbon dioxide, the liquor after removal of sulphuretted hydrogen is heated and the carbon dioxide evolved used for regenerating the absorbent. Steam or any inert gas may be passed into the liquor to facilitate the removal of the carbon dioxide.  Losses of carbon dioxide during the removal of the sulphuretted hydrogen are made up by the absorption of carbon dioxide from the gas being purified.  Heat interchangers may be used in which the regenerated absorbent is cooled before re-use by the liquor coming from the absorbers.  Potash is preferred as the absorbent since the carbonate and bicarbonate are more soluble than those of sodium.

Patent GB-582770-A (GB)
Title: Sponge rubber
IPC: C08L21/00
Filed: 1944-04-17
Abstract: Low-density natural or synthetic rubber sponge is produced by mixing with a curable latex composition a frothing agent, e.g., ammonium oleate, and a blowing agent which liberates gas only at a temperature above that at which the latex can be partially cured, e.g., diazoamino -benzene, -toluene, -methane, -napthalene or that known under the Registered Trade Mark "Unicel," frothing the latex, adding a gelling agent, e.g., sodium silicofluoride, and allowing the frothed latex to gel, partially curing below the temperature at which gas is liberated, e.g., by steam or hot water at about 212 DEG F., and then heating, e.g., by steam or hot air up to 300 DEG F., to liberate the gas and expand the rubber and complete the cure.  The partial cure may be effected in one mould and the cure completed in another.  In an example, 60 per cent. latex and aqueous dispersion containing 50 per cent. solids of sulphur, zinc oxide, the accelerators tetramethylthiuram disulphide and the zinc salt of 2-mercaptobenzothiazole, and an antioxidant consisting of a condensation product of butyraldehyde and aniline are employed.

Patent GB-731991-A (GB)
Title: Improvements in or relating to method and apparatus for cold-reducing metal bars
IPC: B21B39/00
Filed: 1953-03-17
Abstract: 731,991. Rolling; drawing. FISK, G. L. March 17, 1953, No. 7306/53. Class 83 (4). In a method of cold-rolling or cold-drawing metal bars, tension is applied by resilient frictional gripping means progressively engaging the work. Rolls 8, Figs. 1 and 2, for drawing a bar 11 through a rolling mill have a rim 9 of yielding material supporting a belt 14 in engagement with the work and are over-hung on driven vertical spindles 4, 5 rotating in housings 1, 2 which are adjustable towards or away from the work. The yielding rim 9 of each roll comprises a bonded rubber cushion 71, Figs. 4, 5, and a ring of spring steel pins 69 embedded in a layer 68 of rubber-impregnated fabric. An outer tread ring 66 of spring steel provides a hard seating for the belt 14. A groove 15 in the belt 14 is shaped to fit the particular size of bar being rolled and the belts are interchangeable for different sizes of bar. The belts run over pulleys 16 on eccentric spindles 18 adjusted by worms 19 for maintaining the belts under tension and a pair of rolls 21, 22 at the sides retain the belts in position. In applications in which tension rolls 105, 106, Fig. 9, are placed on each side of the last roll stand 104 of a continuous cold rolling mill 100, coils 78 of bars to be rolled are first brought by a carriage 80 to an uncoiler 85 which feeds the end of the bar to an end squaring shear 89<SP>1</SP> after which the ends are butt-welded to leading bars stored on a bed 91. After welding, the coil 78 and leading bar are moved transversely to an uncoiler 95 in line with the cold rolling mill through which the bar is fed as the uncoiler 95 is moved along tracks 97 to a position 98. By the use of the leading bar of section substantially the same as that of the required rolled product, the leading end of the work is maintained under tension between the tension rolls 105, 106 during rolling. In a similar application, oval bars to be rolled are prevented from turning round in the rolls by guides 120, Figs. 18, 19 placed on the entry and exit sides of the mill rolls. Each guide carries a grooved roll 123 running on roller bearings 124, and engaging the oval section 116 of the bar.

Abstract: 1,180,581. Valves. GARRETT CORP. 15 Feb., 1967 [15 Feb., 1966], No. 7327/67. Heading F2V. [Also in Divisions F1, F4 and G3] In a system for supplying air to an aircraft cabin from high and low pressure stages of the aircraft engine (see Division G3), the low pressure supply is normally adequate and is controlled automatically by a valve sleeve 34 integral with a piston 35, the air passing to the cabin from inlet 21 via duct 10. Should the low pressure supply prove inadequate, piston 35 withdraws the free end of a second valve sleeve 33 from recess 36 in profiled body 25 and high pressure air flows from inlet 22 to duct 10 via ejector passage 30 and thereby augments the low pressure supply. The duct 10 may also supply an engine starter and, when so used, air at a constant regulated pressure derived from inlet 22 is supplied to chamber 38 to bias sleeve 34 to its open position against spring 41. Static pressure at 74 downstream of Venturi 24 is communicated to chamber 40 via line 73 and passage 63 where it acts on piston 35 to maintain a constant supply pressure to the engine starter.

Title: Holding device for use between two relatively movable structures
IPC: E05D11/06
Filed: 1958-03-07
Abstract: 833,844. Door stays. SCHONITZER, R. I. March 7, 1958 [April 3, 1957], No. 7370/58. Class 65(1)] A holding device for use between relatively movable structures comprises an arm for connection to one structure of a body, through which the arm passes, which has limited movement relative to the other, structure and carries means responsive to that movement to clamp or release the arm. As applied to a door check in which a vehicle door is held, against the weight of the door, in an open position, but is released when further door closing effort is applied, the device comprises, Figs. 2 and 5, an arm 13 pivoted to the door frame and extending between the plates 29a, 29b, forming a body 29 which is movable within limits between two walls 22, 23 of the door. The plates are connected at one end by a pin 35 which carries spring washers 52 to form one clamping element, and at the other end by a pin 37 engaging elongated holes 38 in the plates, springs 48, one each side of the body 29, engaging grooves 36 in the pins. The pin 37 forms a pivot for an actuating member 33 provided with an arcuate cam edge 43, a clamping element 31 and a pin 55 which extends through an elongated hole 56 in each plate. The arm carries at its free end a disc 62 which abuts a flexible bumper 63 on the wall 23 when the door is fully open. As the door is opened, Fig. 6, the wall 22 abuts the spring 48 to tilt the body 29, the pin 55 of the actuating member 33 being then disposed in the end of the elongated hole nearer the wall 22, the arm passing freely through the body. When the door is released, Fig. 7, and moves by its own weight towards the closed position the door wall abuts the cam edge 43 of the actuating member to rotate it clockwise about the pin 37, when the clamping element 31 forces the arm between the spring washers 52 of the abutment element to hold the door in the open position. On the application of further door closing effort, the wall 23 further rotates the actuating element and the pin 55 moves across the line of action of the spring force on the pin 37 to the other end of the elongated hole 56, releasing the clamping force applied by the clamping element 31 to the arm, and the door moves towards. its closed position. When the door is fully closed the clamping element engages a notch 60 in the arm so that when the door is again opened the actuating member is tripped back into the position shown in Fig. 6, the pin 55 returning through the dead centre position to the first mentioned end of the elongated hole 56. In a modification the body carries a roller acting as both a stop and a guide for the arm 13.
