Title: Improvements in or relating to the manufacture of gas
IPC: C10B1/04
Filed: 1925-06-20
Abstract: 262,834. Nielsen, H., and Laing, B. June 20, 1925. Producers.-Producer gas rich in carbon monoxide is obtained by passing carbon dioxide through a retort containing semi-coke at a temperature of 750‹-800‹ C. The semi-coke is obtained by distillation at 400‹-800‹ C., preferably by internal heating and the coke or the gas or both may be preheated to the required temperature. The gas, for example combustion products, passes through a heating chamber 6 into a retort 1 with baffles 2, and after traversing the mass of semi-coke escapes as carbon monoxide through an outlet 12. The resulting gas may be recirculated through the charge; and its sensible heat may be utilized for distilling coal.
Patent GB-815225-A (GB)
Title: Manufacture of co-polyamides
IPC: C08G69/00
Filed: 1955-06-06
Abstract: Polyamides having improved dye affinity and water absorption are obtained by reacting an amino-carboxylic acid, or amide forming derivative thereof or a polyamide derived therefrom at polyamide-forming temperatures with 2 to 30 per cent of its weight of a vinyl polymer derived predominantly from a vinylated nitrogenous heterocyclic compound and containing carboxyl or equivalent groups. The resulting polymer may be branched or cross-linked depending on the number of carboxyl groups in the vinyl polymer.  The product may be further reacted with compounds containing basic nitrogen to further increase the dye-affinity, e.g. 6 - pyrrolidino - hexanol - 1; 6 - morpholino -, hexanol - 1; 6 - pyrrolidino - hexylamine-1; and 2-(5-aminoamyl) benzimidazole.  The product may also be reacted with compounds mono- or polyfunctional with respect to carboxyl groups, e.g. amines, isocyanates, diepoxides and alkylene oxides.  This further reaction may be conducted on the formed article; e.g. threads may be saturated with 6 pyrrolidino-hexylamine-1 or 2-(51-aminoamyl) benzimidazole, dried and heated to cause reaction.  With polyfunctional reactants cross-linking occurs. Such cross-linking can be allowed to occur to a limited extent towards the end of the polyamide-forming reaction to give leather-like products which can be processed by pressing or rolling.  In examples: (1) caprolactam containing 10 per cent water is heated with 10 per cent by weight of a copolymer from 5 parts acrylic acid and 95 parts vinyl pyrrolidone for 2 hours at 270 DEG  C. and a further hour at 250 DEG  C. under reduced pressure.  A colourless product is obtained which can be spun and colddrawn and has good water absorption and dye-affinity.  (2) Similar to (1) but using a copolymer from 90 per cent vinyl pyrrolidone, 5 per cent N-vinyl-imidazole and 5 per cent acrylic acid, the polycondensation being effected continuously at 270 DEG  C. for 40 minutes with subsequent vacuum removal of volatiles.  Other nitrogenous heterocyclic vinyl monomers referred to are N-vinyl piperidone, N-vinyl caprolactam, N-vinyl succinimide, N-vinyl-diglycollic acid imide, N-vinyl benzimidazole, 2-vinyl pyridine and 2-vinyl thiazole.

Title: Improvements in and relating to movable floor vehicles
IPC: B60P1/36
Filed: 1939-06-03
Abstract: 529,551. Vehicle fittings for loading. MACLACHLAN, A. June 3, 1939, No. 16340. [Class 78 (iv)] The movable floor of a vehicle, comprising a band or belt supported on rollers which each extend right across or right along the vehicle is fitted with cam mechanism adapted to be raised to bear against the under surfaces and thus support these rollers at an intermediate point in their length when unusually heavy loads are being negotiated. In the illustrated form a belt 5 of impregnated rubber fabric, extending the full width of the vehicle, is supported on the rollers 4 on the carrying run and on rollers 26 during the return run. The rollers 4 preferably are tubular and surround cross rods on the vehicle frame, ball bearings being interposed between the rods and tubes. A pair of chains 9, passing over driving sprockets 10, connect metal strips 8, 17 at the opposite ends of the band to make the latter endless in character. The metal strip 17 also carries an L- shaped load-pushing wall 18 provided with forwardly-directed side-wall-scraping elements 22, for example steel scrapers or composite squeegees of metal and rubber. The horizontal members of the wall rest on the rollers 4 and may also be modified to engage guides on the frame in cases where heavy loads would cause them to tilt. To support the rollers 4 intermediately, a shaft 27, Fig. 3, is mounted on upwardlybowed cross members 1 which space and support the vehicle sides. This shaft can be rotated through a limited angle so that camshaped members 14 are brought into acting and idle positions respectively. The shafts 27 and 11 are interlocked so that the floor cannot be driven unless the cams are in the idle position. Hand-operated gearing applied to the shaft 11 is employed to drive the floor.

Abstract: 889,663. Selective printing processes. RANKXEROX Ltd. May 21, 1958 [June 6, 1957], No. 16353/58. Classes 100(2) and 100(4) An electrostatic selective printer for use with information supplied at a random rate comprises a drum 11 rotating at a constant speed and having an identical electrically interconnected ring for each character printing position of a line of print each ring 64 having raised characters 13 one of which is caused by a pulse fed to the drum 11 each revolution to impress an electrostatic image on an insulating surface of a sheet 10 under that one of electrodes 14 which is activated by a bias voltage. Magnetic marks 15 are sensed by head 16 and the voltage surges are shaped into pulses by a former 17 before being fed to a binery counter 18. Input information is fed into a storage register 23 and when one of the successive values established in the counter 18 coincides with the value held in the register 23 a pulse from the former 17 through a delay circuit 25 to the comparitor 24 is fed through a blocking oscillator 26 to the drum 11 causing the character then under the activated electrode 14 to form an image on the sheet 10. A pulse from the blocking oscillator is also fed through a delay circuit 28 to a ring counter 27 causing it to transfer the bias of the activated electrode to the next in preparation for printing therein immediately after the image has been formed. The counter 27 activates each electrode 14 in turn by transferring the bias in this way until the end of the line is reached when the bias is transferred to the beginning again this latter transfer causing an indexing mechanism 30 to advance the record paper one line of space. A buffer storage is provided for the input information so that it is not fed to the system during the time the paper is fed. A mark 20 read by a head 21 on each revolution of the drum 11 causes a pulse in the former 22 to reset the counter 18. Specifications 679,533, 693,905 and U.S.A. Specifications 2,551,582 and 2,576,047 are referred to.
