Title: Improvements in or relating to the low temperature carbonisation of fuels
IPC: C10B49/00
Filed: 1937-06-10
Abstract: 492,072. Low temperature carbonization. METALLGES. AKT.-GES. June 10, 1937, No. 16110. Convention date, July 4, 1936. [Class 55 (i)] In the low temperature carbonization of fuel, preferably briquetted, in a vertical retort in which carbonization and cooling zones 2 and 4 are formed by maintaining separate gas circulations therein, the offtakes 9b in the upper part of the cooling zone and the gas-inlets 9a in the lower part of the carbonization zone are staggered relatively to each other and are interconnected through a blower or injector so that by adjustment of the operation of the latter a differential pressure is maintained between the zones to allow a part of the gas entering into the carbonization zone through the gas-inlets 9a to be spread over the whole area of the retort and to be withdrawn with the gas circulating in the cooling zone through the offtakes 9b. The mixture of gases is withdrawn by a pair of blowers 10a, 10b and mixed in a pipe 11 with heating gas from a combustion chamber 8, the resulting hot gases at a temperature of 500-600‹ C. being supplied to the gasinlets of the carbonization zone. The gas is withdrawn from the latter through offtakes 14 by a fan 13 and after circulation through a condensing plant 16 is returned through pipe 17 to the base of the cooling zone. Part of the gas from the carbonization zone is byepassed through pipe 18 to the burners 19, fed with air through pipe 21, of the combustion chamber 8. Excess gas is withdrawn at 20. The offtakes and intakes 9a, 9b, are constructed with roof-shaped hoods. In a modification of the invention, the blowers 10a, 10b are replaced by an injector, the nozzle of which enters a mixing chamber connected both to the offtakes 9b and intakes 9a and is fed with heating gas from a compression chamber communicating with the combustion chamber 8. The injector is operated either by a blower arranged in a byepass between the offtake pipe from the outlets 9b and the compression chamber or by a blower arranged in the byepass which feeds the burners of the combustion chamber with combustible gas. Specification 242,618, [Class 55 (i)], is referred to.

Title: Improvements in interlocking frames for railway signalling
IPC: B61L19/02
Filed: 1930-05-26
Abstract: 356,114. Railway signal interlocking frames. VEREINIGTE EISENBAHNSIGNALWERKE GES., Siemensstadt, Berlin. May 26, 1930, No. 16220. Convention date, March 27. [Class 105.] In an interlocking frame employing rotatable shaft levers there are provided locking elements which are movable perpendicularly to the shafts and rotated with the shafts. A four lever frame is shown in Fig. 15 in the unoperated position, while Figs. 16 and 17 show two different interlocking positions. The levers 41, 51 .. and locking cams 42, 58 .. are shown lying in the plane of the rocking shafts 4, 5 .. but actually are at rightangles thereto. The levers 51, 61, 81 control the signals and points while the lever 41 is a route locking lever which on movement to the position shown in Fig. 16 displaces, by its segment-shaped cam 42, a sliding piece 15 which butts against a flat face 65 of a cam 58 on the shaft 5 and so locks the lever 51. The shaft 5 carries in addition movable cams 38, 39 which are slotted to slide transversely and are therefore displaced by an extension of the locking piece 15; the cam 39 moves a locking piece 24 against a flat face of the cam 62 on shaft 6 which with its lever 61 is therelocked but the cam 38 has no action since, in the position of the lever 51, shown in Fig. 16, its full diameter is not effective. In the position of the levers shown in Fig. 17, the lever 51 is locked by the piece 15 engaging the flat face 57 of cam 58, the slotted cam 39 is ineffective, but the slotted cam 38 is now in a position with its full diameter effective and on displacement by the piece 15 moves the locking piece 26 and its connected locking piece 28 the latter engaging the flat of cam 82 and thereby locking the shaft 8 of lever 81. The slots in the movable cam discs 38, 39 may be eccentrically situated. The locking pieces 24, 26, 28, or the sliding rods to which they are secured, may run on ball bearings. The cam discs may be spaced along their shaft by sleeve distance pieces. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which a rocking shaft is adapted to insert a member 108 in the space between two sliding tappets 109, 110 which must thereupon move together, Fig. 1a (Cancelled) or between an abutment 103 and a tappet 104 which is thereupon locked, Fig. 1 (Cancelled). This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to polymerizable compositions
IPC: C09J4/00
Filed: 1951-07-11
Abstract: Solid polymeric materials are made by oxygenating an ester derived from methacrylic acid and a glycol, containing at least two methacrylate groups and having one or more ether linkages in the glycol portion, by passing oxygen through the ester at a temperature of 25 DEG  C. to 90 DEG  C. until at least 0.1 per cent of combined oxygen is introduced, and thereafter excluding oxygen while effecting polymerization.  Esters specified are the dimethacrylates of diethylene, triethylene, tetraethylene, polyethylene, dipropylene, and dipentamethylene glycols, and diglycerol tetramethacrylate. Oxygenation may be carried out with air, oxygen, or ozone, or mixtures thereof, and may be accelerated by the addition of a small quantity of a peroxide such as benzoyl peroxide, tert.-butyl perbenzoate, di-tert.-butyl perphthalate, and tert.-butyl hydroperoxide, or by the addition of a small quantity of the oxygenated monomer obtained previously.  After oxygenation the monomer does not undergo polymerization whilst still in contact with oxygen or air, but under anaerobic conditions polymerization takes place rapidly at room temperature. If desired a mixture of a glycol dimethacrylate and monomethacrylate may be oxygenated and then polymerized.  The polymerization of the oxygenated esters may be used in bonding applications and in sealing leaks.  Specifications 549,234 and 573,175 are referred to.ALSO:Diethylene glycol monoethyl ether monomethacrylate and diglycerol tetramethacrylate are prepared by heating respectively diethylene glycol monoethyl ether and diglycerol with methacrylyl chloride, and then, at the end of the reaction, removing excess methacrylyl chloride and residual hydrochloric acid in a vacuum. Specifications 549,234 and 573,175 are referred to.

[Also in Division A3] A method of moulding and vulcanizing soles on to shoe bottoms comprises the steps of (a) supporting the shoe in operative position relative to a heated mould arrangement, (b) applying to the sole material at an early stage in the vulcanizing cycle a " maximum " pressure sufficient to cause the material to assume the sole shape and (c) thereafter rapidly reducing the pressure to a " minimum," sufficient to maintain the sole shape and prevent the formation of bubbles. This method can be performed on the machine disclosed in Specification 1,025,641, comprising a foot form supporting the shoe, a heated mould arrangement comprising a sole mould and a pair of side moulds, and power operated means for moving the side and sole moulds. The power operated means comprise fluid pressure operated means in a fluid pressure circuit of the machine. When the foot-form and side moulds are in their operative-positions oil under pressure is admitted to cylinders 3 (Fig. 1, not shown) beneath pistons 2 to raise rams 5 carrying the sole moulds, and a reducing valve 4 is included in the hydraulic unit through which oil is pumped. When the oil in the supply to piston 2 reaches an amount sufficient to overcome springs 6, 8 (Fig. 2, not shown) a spool valve 18 between the oil inlet chamber 12 and the oil outlet chamber 14 is closed. The initial " maximum " pressure is provided by compressing the spring 6 to increase its loading on the spool valve 18 as follows. A solenoid 64 can be energized to open valve 65 in a subsidiary hydraulic circuit to admit oil under pressure to a cylinder 72. A piston 74 in the cylinder 72 has a piston-rod 73 connected to a lever 76, one end of which is pivoted and the other end of which is forked to embrace a collar 80 slidably mounted on the casing 36 of the valve 4 and supported by flanges 31 on a sleeve 32. When the solenoid is energized the piston 74 moves so as to depress the collar 80, depressing the sleeve 32 to compress the spring 6. At the end of the time needed to maintain the " maximum " pressure, the solenoid is deenergized by means of a presettable electrical timing device causing the decompression of spring 6 to its former value.
