Abstract: 937,323. Glass melting furnaces. G. HENRY. June 27, 1960 [June 26, 1959], No. 22469/60. Class 51 (2). [Also in Group XXIII] The operating conditions of a tank furnace are controlled by a vertically adjustable hollow screen comprised of vertical tubular members 26 suspended through a slot 13 in the arched roof of an intermediate zone between a washing zone 6 and a melting and refining zone 3 of the furnace, each tubular element having at least one inlet or outlet for a temperature regulating medium. The screen may be formed of separate elements 26 closed at the bottom, Fig. 4, and suspended by straps 27 from a beam 28 supported outside the furnace from pulleys 30 mounted on the furnace supporting structure 22. The interior of each element may be divided by a transverse partition 40, Fig. 7, pipes 44 for coolant passing through the partition, which may be mounted in an inner sleeve sliding within the element, Fig. 11, not shown. The space above the partition 40 may be filled with insulating material. The elements may be of polygonal cross-section, Fig. 10, with a pointed nose part, containing the coolant pipes 44, directed towards the washing zone. Each element may be open at the bottom, or the elements may have outlets 58, 59, Fig. 15, controlled by a rotary valve 62. Another form of element, Fig. 16, has a burner 71 mounted within it, together with a supply 68 for air or other coolant. The element has an outlet 67 and is rotatably mounted in an annular support 73. The elements may be fixed to toothed racks 79, Fig. 20, guided between rollers 81 in a wheeled frame 82 which can be moved transversely of the furnace. Each element may be raised or lowered by a pinion 85 engaging the rack 80 and driven by a worm gearing 86, 87. The tubular elements may be joined together to form a single plate with parallel ducts, Fig. 18, not shown.

Abstract: 850,073. Control of several D.C. motors. ENGLISH ELECTRIC CO. Ltd. July 11, 1957 [July 20, 1956], No. 22541/56. Class 38 (3). Relates to a traction system in which motors M1-M6 are each coupled to separate axles and are connected in three groups, each consisting of two series-connected motors, to be supplied from generator G driven by a diesel engine. Wheel-slip relays WSR1, WSR3, are connected across shunts A1, A2, in equalizer-connections E1, E2, and response of either of these relays causes the generator field regulator FR to be driven in a direction to reduce the tractive effort of the motors. Relays WSR2, WSR4, respond to a higher degree of wheel slip to deenergize the generator field winding Gf and to disconnect the motors. The regulator FR may be of the governor-controlled type for automatically matching the generator output to the available engine horsepower. Operation of either of the relays WSR1, WSR3, causes the energization of an alarm buzzer.

Patent GB-226299-A (GB)
Abstract: 226,299. Frymann & Fletcher, Ltd., and Fletcher, S. S. Sept. 27, 1923. Knitted fabrics.-A warp fabric with a permanent embossed effect, which is developed in the process of dyeing and finishing, is made from heavily tensioned ground threads which pillar on neighbouring needles and from lightly tensioned facing threads which pillar alternately on needles which are remote from one another, say, the space of eight needles apart. In the finishing process the ground fabric shrinks more than the facing fabric, giving a wavy effect, as at D, which cannot be fully controlled, but can be accentuated by using cotton and artificial silk for the ground and face respectively and by dressing out the fabric as long as possible and maintaining it on a frame until dry. By omitting facing threads at intervals vertical stripes F may be produced, threads of the same material as the facing fabric being preferably used for the ground at such places.

Title: Improvements in or relating to the production of gas from oil
IPC: C10G9/38
Filed: 1946-08-09
Abstract: 615,807. Oil gas. GAS LIGHT & COKE CO., MACCORMAC, M., and LEWIS, C. H. Aug. 9, 1946, Nos. 23624 and 31733. [Class 55 (ii)] An oil gas process comprises introducing atomised oil with air for its partial combustion into an evaporating zone maintained at not more than 350‹C. within an externally heated reaction chamber consisting of a retort of the type normally used for the high temperature carbonisation of coal, so that the oil evaporates and forms a homogeneous mixture with the air, the mixture then passing through a zone where said partial combustion occurs into a zone of high temperature, where the remaining oil and its oxidation products are cracked to form permanentgases and tar, most of the heat for the evaporation of the oil being supplied by recirculating through the evaporating zone a portion of the hot gaseous products of the partial combustion. An open-ended cast-iron pipe 11 is mounted lengthways in a horizontal coal gas retort 12. A sleeve 15, coaxial with and just entering the pipe 11, is secured to the retort door 14 and houses a pressure-type atomising oil jet, supplied with oil through a pipe 18. A steam air-injector 17 forces a controllable amount of air into the sleeve 15 and through the annular space surrounding the jet, whence it passes with the steam and atomised oil into the pipe 11. The injector action of this flow induces a portion of the hot gases from the remote end of the retort to pass back along the outside of pipe 11 and recirculate through the pipe, their heat causing evaporation of the oil, the gases also serving, with the steam, to prevent premature ignition of the oil. After partial combustion, the gases, apart from that portion which is recycled, pass through the remote end of the retort which is heated in the normal way to about 700‹ C. and where cracking and fixing occurs, the permanent gases and tars passing to the gas offtake at the far end of the retort. The gas produced has a high density and low flame speed ; for town's distribution it may be mixed with two or three times its volume of coal gas. The second Provisional Specification describes a form of apparatus comprising an externally unheated, insulated, cylindrical, retort closed at both ends and mounted vertically. Air and atomised oil enter at the top of the retort and pass down through an open ended tube supported axially in the retort, the air being in sufficient quantity to render the process thermally self-supporting. The gases, less those that are recirculated through the tube pass out of an opening at the top of the retort.

Abstract: 701,133. Shearing. HACK, K. W. Oct. 11, 1951 [Oct. 12, 1950], No. 23683/51. Class 83 (4) Severing apparatus for spring coiling machines and the like having a reciprocating knife mounted on a slide and wherein the wire to be severed protrudes from a guide fixed to a frame is characterized in that the cutting pressure is transmitted from the knife to its driving spindle and thence through a bearing for the spindle, mounted in an adjustable block in said slide, and from that block direct to the frame so that the counter pressure on the frame is equalized. The wire is guided to a snipping point a by a bush 1 in a slide guide 3 which is vertically adjustable with respect to the table 5 of the machine by means of bolts sliding in guides 4. A knife 6 secured to a slide 9 by a lug 7 and a screw 8 is adjustable in the cutting direction by a screw-threaded spindle 10. The slide 9 operates in a swallow-tailed groove 17 on the slide guide 3 and has a slot 11 in which are rotatably bedded two rollers 12 on spindles 13 which engage a cam 14 on a driving spindle 16. Firmly wedged on the spindle 16 is a bush 18 having a collar 19 said bush being rotatably mounted in a sliding block 20 which is adjustable in the slide guide by means of threaded spindle 21 and a nut 22 whereby the knife may be set for different coil diameters of the springs to be snipped. The collar 19 on the bush 18 allows the knife to be adjusted for cutting different lengths of spring shanks. In operation the cutting pressure is transmitted from the knife through the rollers 12 and the cam 14 and from the cam spindle 16 through the slide block 20 and spindle 21 direct to the slide guide 3 so that the counter pressure acting on the bush 1 and through this to the slide guide 3 is equalized.
