Patent GB-578579-A (GB)
Title: An improved change speed gear of the hydraulic type
IPC: F16H39/42
Filed: 1945-02-14
Abstract: 578,579. Hydraulic transmissions. HANSON, T. A., and WILSON, H. Feb. 14, 1945, No. 3657. [Class 69 (ii)] An hydraulic change speed gear comprises a driving shaft 1 secured to a casing 2 which houses or supports the cylinders 16 of a series of radially arranged pump units having pistons 22 adapted to be reciprocated therein by a cam 19 mounted on a shaft which forms part of a driven turbine member 12, or the equivalent thereof; the cam being rotated through epicyclic gearing 27, 25, 29 of which the ring 27 is rigid with a cover 26 bolted to the casing 2 ; the speed differential between the casing 2 and the' cam 19 causes the latter to actuate the pumps which draw in fluid through a valve 17 and deliver it through tubes 3 to the space surrounding a sleeve valve 5 adapted to divert some or all of the fluid to passages 9 which byepass passages leading to nozzles 7 which direct the fluid on to the vanes 11 of the turbine member 12, the driven shaft 33 being secured to the shaft portion of that member to rotate therewith. Towards the extreme right position of the valve 5, little or no fluid passes to the nozzles 7 and the turbine does not function and when a flange at the left hand end of the valve closes the tubes 3, there is direct drive. The valve 5 is operated through a rod 35 in an axial bore in the shafts 12 and 33, the rod being actuated manually or by a centrifugal governor 37, in which case the right hand flange of the valve is larger than the left hand one to permit fluid pressure to oppose the governor. Partitions 14, 23 divide the casing into separate sections for the turbine, pump and gear units. The piston pumps may be' set parallel to the shafts 1, 33 and operate through a swashplate or they may be replaced,by vane pumps. The epicyclic gear may be a compound one, if greater speed reduction is necessary to avoid cavitation.

Title: Improvements in or relating to steam generators or heating boilers
IPC: F22B9/04
Filed: 1957-02-04
Abstract: 812,224. Boiler furnaces. OHLSSON, O. A. Feb. 4, 1957 [Feb. 2, 1956 ; May 17, 1956 ; Nov. 2, 1956], No. 3779/57. Class 51 (1). [Also in Group XIII] A steam generator or water-heating boiler comprises an outer water casing 1, Fig. 1, and an inner furnace casing 2 surrounding a lower cyclone chamber and an upper flame chamber wherein primary air is supplied beneath the grate and secondary air from tangential nozzles 17 in the cyclone chamber. The gases pass from the cyclone chamber through an outlet 14 of an annular member 12 whence tertiary air is centrally directed from nozzles 15 up into the flame chamber. The combustion products reflected from the wall 3 flow down to tubes 19 where they are drawn off by chimney draught towards cleaning doors 9 and through tubes 20 to a soot compartment 8, delivering heat to the water casing during their passage. A furnace door 4 has tapered vertical side walls, with the widest section innermost for greater accessibility to the cyclone chamber. In another embodiment, Fig. 2, the boiler is divided into a cyclone radiant section and a convection section connected by a water-cooled gas passage 22. Heating tubes 20a extend between tube-plates 3a to heat a water compartment and a pipe 21 open at both ends allows a free flow of water and steam in the compartment. Steam is drawn from domes 24 by tubes 25 to a common discharge main 26. In a further embodiment, Fig. 3, combustion gases are led from the flame chamber 35 upwardly through tubes 42, 47 which heat a steam dome formed by a cavity beneath a roof 45 into which cold air is introduced in cross-current streams around the tubes by a fan 49. The gases are then led by tubes 47 to an air-tight gas compartment 50 before escaping to a chimney 52.

Filed: 1967-01-27
Abstract: 1,182,841. Vehicle braking systems. GIRLING Ltd. 17 Jan., 1968 [27 Jan., 1967], No. 4165/67. Heading F2F. A control spring for a valve which modifies the braking pressure according to vehicle loading is connected to a link which may be attached to an abutment on a vehicle part in either of two spaced positions such that deflection of the spring is altered by changing from one position to the other. This facilitates setting up of the spring since in one position a predetermined clearance is obtained between the valve and its operating member, and on changing to the other position a known prestressing of the spring is obtained. In Fig. 2 the valve (not shown) is operated by a lever 42 pivoted on a pin 43 fixed by a bracket 41 to a sprung part of the vehicle. The lever is attached to one end of a twin-spiral spring 46, the other end of which is received by a collar 56. The collar 56 is connected by an adjustable link 51 to an eye 57 carrying a bolt 59. For setting up, the bolt 59 is inserted in a hole 61 and the link 51 adjusted for a predetermined clearance between the lever 42 and the valve (X in Fig. 1, not shown). The bolt 59 is then screwed into a hole 60 to produce a predetermined stressing of the spring. In a modification (Fig. 3, not shown) the eye 57 is attached to an eccentric which can be rotated through 180 degrees for the alternative positions. In another modification (Figs. 3 and 4, not shown) the link 51 is of fixed length and the relationship between the lever 42 and the valve is adjustable by a set-screw. The valve may be mounted on an unsprung part of the vehicle.

Abstract: 676,327. Visible signalling apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 22, 1950. [Feb. 25, 1949] No. 4554/50. Drawings to Specification. Class 118 (ii). A system of visible signalling to reduce the influence of interfering light sources, such as daylight, moonlight or artificial light sources, or absorption in the atmosphere by cloud, fog or rain, comprises a device for transmitting intermittent light signals of very short duration and a device for receiving such signals having an obturator adapted to synchronise the said light signals with its open periods by means of a radio link. The system is applicable to airfield-aircraft or ship-shore signalling and the transmitting end comprises a gas-discharge lamp, adapted to flash at a frequency that may be very low or, if an apparently continuous light is required, as high as 25 to 50 c/s ; the operating switch may be mechanical but is preferably electronic. The receiving end is provided with a rotating disc having at least one aperture such that light is allowed to pass to an observer for very short periods approximating to the time of the transmitted flash which may be about 10<SP>-4</SP> second, thereby eliminating a very high proportion of extraneous light. This obturator is adapted to initiate radio pulses from an associated radio transmitter in synchronism with its periods of opening and these pulses are received by a radio receiver associated with the light signal transmitter so that each pulse effects closure of the operating switch and transmission of a light flash. The light signal receiving device may trigger one or more light sources such as beacons marking an airfield or fairway.

Abstract: An epoxy resin composition for use in moulding waveguides (see Group V) comprises a mixture of polyamide and epoxy resins and an inorganic filler, the quantity of polyamide resin being sufficient to react with the epoxy resin so as to harden it without the addition of another hardening agent.  In examples the composition comprises polyamide and epoxy resins and aluminium powder in the proportions 1:1:2 and 3:7:10 by weight, respectively.ALSO:An article is cast by coating the surfaces of a mould with a releasing agent and casting in the mould a mixture of polyamide and epoxy resins together with a relatively large quantity of inorganic filler, the quantity of polyamide resin being sufficient to react with the epoxy resin so as to harden it without the addition of a hardening agent having an exophemic reaction.  In the manufacture of a waveguide equal weights of polyamide and epoxy resins preheated to 30 to 35 DEG C and 25 to 30 DEG C, respectively, are mixed together with a weight of aluminium powder equal to the sum of the weights of the two resins, the mixture being then poured into a mould coated with carnauba wax and allowed to cure at room temperature.  In a further example the mix comprises polyamide and epoxy resins and aluminium powder in the proportions 3 : 7 : 10 by weight.
