Title: Improvements in or relating to cooling systems for the rotors or pistons of rotary piston mechanisms
IPC: F02B55/04
Filed: 1961-06-26
Abstract: 984,764. Rotary engines. NSU MOTORENWERKE A.G., and WANKEL G.m.b.H. June 26, 1961 [June 29, 1960], No. 22997/61. Heading F1F. To cool the rotor of a rotary I.C. engine of the n and n + 1 lobe type, comprising a generally triangular rotor 9, Fig. 2, eccentrically supported for rotation in an outer body having a two-lobed epitrochoid periphery 4, the rotor is formed with a cavity 15 within which is disposed a stationary member 19 having a tubular hub 20 secured to the outer body. The member 19 if formed with radial passages 21 opening at their inner ends to the tubular hub and at their outer ends to the cavity. The profile of the member 19 which is substantially oval with its major axis in alignment with the nodule points on the outer body periphery corresponds to a curve generated by the contour 26 of the rotor cavity during the planetary rotor motion of the rotor so that at all times the radial outer end of at least one of the passages 21 is adjacent to and at a predetermined clearance from the peripheral surface of the rotor cavity. Cooling liquid admitted to the cavity 15 through an outer body passage 16, Fig. 1, an annular chamber 17, and a rotor passage 18 on rotation of the rotor is thrown outwards by centrifugal force against the cavity surface and forced by pumping action between the adjacent surfaces of the member 19 and the rotor cavity through the passages 21 to a coolant radiator. The outer ends of the passages 21 are located radially outwards of the rotor bearing 8 and the gears 13, 14 so that these parts are not immersed in the coolant. As shown in Fig. 2, the apices 10 of the rotor are enlarged to permit the fitting of sealing members 11. In a modified embodiment, the outer contour of the member 19 has two apex portions disposed diametrically adjacent the contour 26 of the rotor cavity. The contour 26 which is of hypotrochoidal form gives a substantially constant relatively small thickness of rotor to reduce rotor weight and improve cooling efficiency.

Title: Improvements in or relating to electrical insulating materials
IPC: C04B41/50
Filed: 1949-09-06
Abstract: A mechanically rigid agglomerate of high electrical resistivity and good thermal insulating properties is made by impregnating asbestos with a mixture of a methyl or methyl phenyl polysiloxane resin and ethyl polysilicate and then subjecting it to heat and pressure at least sufficient to insolubilize the resin, the temperature used being preferably substantially higher than is necessary for this. The polysiloxane resin and ethyl polysilicate may be applied to the asbestos as a solution in a common solvent, e.g. mixtures of methanol, benzene and ethyl acetate.  The asbestos may be in the form of board, felt, flock or loaded asbestos.  The impregnating solution may be made by forming a solution of a methyl or methyl phenyl polysiloxane resin and ethyl silicate in a common solvent, diluting it with methanol and water containing a small proportion of hydrochloric acid, and stirring; or the ethyl silicate may first be partially hydrolysed, either alone or in alcoholic solution, by very dilute hydrochloric acid, and then mixed with the polysiloxane resin or its solution. The resin may be present in the proportion of 0.5 to 20 parts by weight, and the ethyl polysilicate of from 2.5 to 20 parts per 100 parts of asbestos.  The impregnated asbestos may be pre-heated under normal or reduced pressure to about 100 DEG  C., and is agglomerated by heating in a press, temperatures above 200 DEG C., and pressures above 300 kg. sq. cm. being used for this.  In examples, comparative figures for the electrical and mechanical properties of agglomerated asbestos treated according to the invention, or agglomerated by ethyl polysilicate alone, and baked, are given.  Example I also describes, by way of comparison, asbestos treated with ethyl polysilicate, heated under pressure, treated with a polysiloxane resin, and baked.  Example VII describes a methyl/phenyl polysiloxane resin made by hydrolysing 33 per cent by weight of methyl trichlorosilane, 7 per cent of dimethyl dichlorosilane and 60 per cent of phenyl tri-chlorosilane. Specification 682,959 is referred to.

Title: Improvements in liquid rheostats
IPC: H01C10/02
Filed: 1921-09-01
Abstract: 170,559. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of Whittaker, C. C.). Oct. 18, 1920, [Convention date]. Controllers, liquid; systems for alternating-current motors only. - In liquid rheostats employed in motor - control systems traversed by relatively large alternating currents, the depth of the continuously circulating electrolyte is regulated by a weir comprising a number of pivotal shutters, the m a i n electrodes being connected in delta through the electrolyte until the level of the liquid reaches a number of ground electrodes, when a star connection with the main electrodes is formed in addition to the delta connection. The electrolyte is pumped into the rheostat 5 and its level is varied by opening or closing pivotal shutters 36 operated by rods 38 connected to pistons 44 actuated by electromagnetically-operated valve elements. Main electrodes 18 of Y cross-section insulated from the top plate 25a have their lower legs spaced by soapstone barriers 19. Auxiliary electrodes 21 are mounted between the upper legs of the main electrodes and are electrically connected by bolts 22 to end plates 27. The auxiliary electrodes comprise two plates welded or bolted together to form a V cross-section. Ground electrodes 26 are secured to the top plate by angle-pieces and are thus electrically connected with the end plates. The soapstone barriers are positioned in staggered relationship and are cut to resemble a V when in position, their sloped portions being formed with a sharp edge to prevent eddies of the electrolyte. A large notch 26<a> in each ground electrode is in substantial alignment with the openings formed by the staggered soapstones, so that the portions of these electrodes first immersed by the electrolyte are farthest from the direct path of current. When the electrolyte is below the ground electrodes the main electrodes are connected in delta through the electrolyte, and as the electrolyte immerses the ground electrodes, the main electrodes are connected in star through the electrolyte, the delta connection remaining, and the auxiliary electrodes providing an additional path to the ground electrodes and end plates as the electrolyte continues to rise. Any leakage of the electrolyte passes into the air space 53 between inner and outer walls 51<a>, 51 of the container and drains into the reservoir by way of the opening 54.

Title: Improvements in the process of distilling oil shales, coal and other carbonaceous materials, and in apparatus therefor
IPC: C10B7/02
Filed: 1921-09-01
Abstract: 189,542. Ironside, T. G. Sept. 1, 1921. Evaporating by mixing with hot granular material.-In the distillation of liquid carbonaceous material the liquid material is mixed with a heated granular substance such as sand, which supplies the necessary heat. The material, which may be preheated, is fed from a hopper 19 to a tube 22 leading into a retort 1 and the heated granular material such as sand is supplied from a jacketed container 25 through a tube 40. On the lower end of a rotarv shaft 57 are radial arms 63 to which are fixed angularly disposed blades 64<a> which serve to mix the material and hot sand and deliver the residue to a central discharge pipe 66 closed at the bottom by a conical valve 67 which opens when the weight of the superimposed material is sufficient. The distillates are taken off by an outlet 8. Steam, vapour, or gas may be supplied to the retort, preferably through a hollow shaft leading to hollow stirrers perforated to permit of the gas passing into the material. The retort may be externally heated by hot gases in the space 12 surrounding the retort, and the latter may be divided by horizontal floors so that the material is caused to travel from the periphery to the centre of one floor, then through a central opening on to the floor next below, and from the centre to the periphery of this floor and so on. The retort may be provided with shelves 90, Fig. 12, arranged horizontally or at an inclination so that the carbonaceous material which is supplied to the top shelf, from a hopper 88 and the hot sand from a pipe 89, gravitate through the retort and are mixed while falling from shelf to shelf. In addition to or instead of the pipe 89 and hopper 88, pipes 91 may be employed to introduce the material or sand at any desired point. The material may be agitated by reciprocating, rotating, or otherwise shaking the surfaces, and the mixing of the material may be assisted by mechanical stirrers. In the construction shown in Fig. 13 the steps 92 are arranged in cascade fashion either horizontally or inclined, alternate steps being widened or narrowed at their delivery end, and the retort may be divided into compartments by partitions 96, and may have separate gas outlets 99 and additional delivery pipes 97 for the material.

Abstract: 1344351 Digital data readout HONEYWELL INFORMATION SYSTEMS Inc 19 April 1971 [4 May 1970] 23651/71 Heading G4C Digital information readout apparatus detects missing bits from double transition encoded data, e.g. on a magnetic medium. Double transition recording includes double frequency encoding and phase encoding by means of which missing data bits and clock bits are respectively detected. Double frequency coding (Figs. 1 and 3).- Here clock bits C and data bits D alternate as shown in waveform A1, Fig. 3, with one clock cell and one data cell making a period. The data 0 or 1 depends on whether the data bit is there or not. Owing to magnetic crowding, mechanical jitter and electrical effects the bit positions may vary causing long and short cells as shown in waveform A2. The apparatus of Fig. 1 includes a first circuit 10 which delays A3 (the inverse of A2) and combines it with A3 in a JK flip-flop 24 to produce waveform C the pulses of which are initiated by the start of a delayed bit in delayed waveform B and ended by the start of the next bit in waveform A3. Waveform C enters the low pass digital filter 12 which produces an output signal E when a data bit is missing. The delay times are set depending on possible cell times. A circuit 14 is also provided for extracting clock bits.  Phase encoding (Figs. 2 and 4, not shown).- In phase encoding the polarity of each recorded transition is representative of the bits stored in a given data cell. The apparatus is similar to that of Fig. 1 with the addition of a bi-stable, and the output indicates when a clock bit is missing.
