Patent GB-283295-A (GB)
Abstract: 283,295. Brockies, A. C. Oct. 13, 1926. Counting-apparatus.-Numerical indicating or counting drums adapted to pass in either direction through a zero reading have at least two sets of numerals on each and a pair of apertured superposed shutters controlling the exposure of the sets, one shutter being moved by the highest drum and the other by the lowest. In the form shown adapted to read up to 29¥ left or right, the three drums a, b, c are provided with red and black digits as illustrated in the developed views given in Figs. 19-21 and are mounted in a framework having a cover plate 1, slotted at 1<b> to expose the reading, Below this plate is slidably mounted a shutter 2, slotted and lettered as shown in Fig. 15, and below this again is another shutter 3, Fig. 17, having two apertures only. To the lowest drum or its shaft d is fixed a cam 6, Fig. 22, engaging a lug on the lower shutter 3 which is thus caused to shift longitudinally once per half-revolution of the drum. The upper shutter is controlled in position by another cam 4 rotated synchronously by drum c through intermittent gear o<1>, x, z, z<1> so that when this drum passes through zero the shutter is displaced to change the word " right " or " left " visible in the apertures 1<a> and also to expose the other sets of digits on the drums. Drum a transfers at each half-rotation by means of two opposite transfer teeth m<1>, m<2> and the intermediate gears r, t, t'. Transfers from drum b are effected in two steps by means of teeth n<1>, n<2> arranged at 36‹ apart, the numerals on drum c consequently being repeated. For " right " readings the transfers proceed in the necessary manner and the reciprocations of the lower shutter 3 do not affect the exposure of the black figures through the apertures 2<b>, 2<d>, 2<e>. When however there occurs a change-over from right to left values, the drum c displaces the upper shutter to display the word " left " and to position all the apertures over the rows of red figures. Thenceforth the numbers are progressively exposed, the transfers, the reciprocation of the lower shutter and the repetitions of the numerals co-operating to this end. Specification 125,454, [Class 40 (i), Electric signalling systems &c.], is referred to.

Filed: 1946-09-25
Abstract: 616,953. Gas turbine plant. PARSONS & CO., Ltd., C. A., and BOWDEN, A. T. Sept. 25, 1946, No. 28658. [Class 110 (iii)] [Also in Group XIII] The working medium of a gas turbine plant is heated indirectly by combustion products which are not expanded in an internal-combustion engine and an auxiliary fluid which is itself heated by the combustion products. Air compressed in a compressor a passes wholly or in part through an exhaust gas heat-exchanger b to a heat-exchanger c where it is heated by an auxiliary fluid, e.g. water, steam or a mixture of water and steam, which is in turn heated by combustion products in a heat-exchanger e. The air is then further heated in a heater d by the combustion products and passes to the turbine f, the exhaust of which passes wholly or in part through the heat-exchanger b. The air leaving the heat-exchanger b may be cooled in a cooler g and then returned to the inlet of the compressor a. The invention may be applied to a plant in which the working medium flows in an open circuit. The auxiliary fluid preferably has a higher heat capacity or density than the working medium.

Title: Improvements in or relating to the production of dispersions of synthetic resins
IPC: C08J3/02
Filed: 1946-09-25
Abstract: A process for the production of a resin dispersion consists in the steps of dispersing a thermo-setting melamine-formaldehyde resin in the partially condensed or polymerized hydrophobic state, dispersed in a liquid medium comprising a non-basic, water-soluble dihydric or trihydric alcohol, and adding to the resulting dispersion a stabilizing agent comprising lactic acid in the proportion of at least 0.2 part of the acid per 1 part of the resin.  The resin is insoluble in water at concentrations below 35 per cent, and soluble between 35-70 per cent.  The preferred resin is partially condensed trimethylol melamine water-soluble at concentrations between 50 and 65 per cent.  Ethylene glycol and glycerine, respectively, are the preferred di- and tri-hydric alcohols.  Preferably, 1 part of resin is dispersed in two parts of the alcohol and 0.6 to 1 part of lactic acid is then added.  In examples (1), (3) and (4), partially condensed tri-methylol melamine is dispersed in glycerol and lactic acid and water are added; (2) ethylene glycol replaces the glycerol of example (1). The dispersion may be used to anchor moisture-proofed surface coating to regenerated cellulose film.  Specifications 593,946 and 626,875, [Group VIII], are referred to.

IPC: G21C7/26
Filed: 1960-08-19
Abstract: 915,370. Nuclear reactors. GENERAL ELECTRIC CO. Ltd. June 29, 1961 [Aug. 19, 1960], No. 28796/60. Class 39 (4). A core structure for a heterogenous nuclear reactor comprises fuel channels formed in a moderating material such that in each of a number of the channels a fuel element may be substituted for a removable plug of a moderating material, so that the degree of under-moderation may be varied. The fuel channels in the core structure are in a uniform triangular lattice pitch, and in order to "flatten" the neutron flux distribution a zone of the core (Fig. 2a) is provided with some channels which may be filled with either fuel elements or moderating plugs, which may be of the same material as the moderator. These channels are shown enlarged for clarity in Fig. 2a. Under-moderation in the zone is increased by withdrawing the plugs from the channels and replacing them with fuel, so that the zone would have a depressed flux distribution, thus giving rise to " flattening " without neutron wastage. The plugged channel is every nth (where n is 3 in Fig. 1a (not shown) and 7 in Fig. 2a) in a direction parallel to any side of the triangular lattice. The typical pattern of the disposition in the plugged zone is indicated at' 12, and is different from the triangular pitch typified at 11 of the unplugged zone (Fig. 2b). As shown each plugged channel is surrounded by unplugged channels.

Title: Control device for an hydraulically actuated implement
IPC: F15B11/08
Filed: 1973-06-18
Abstract: 1387367 Hydraulic control circuits ROBERT BOSCH GmbH 18 June 1973 [5 July 1972] 28889/73 Heading F1P [Also in Division F2] In the circuit shown, Fig.1, when a selector switch 56 is in a neutral position, fluid from a pump 4 flows through ducts 3, 28, 29, 41, and 42 into a chamber 23 so that a spool 13 of a changeover valve 12 is moved to the left. This connects a passage 19 to the inlet 3 so that an auxiliary load 20 can be operated. To pressurize a main actuator 35, the selector 56 is moved to the right to energize an electromagnet 26 which controls a pilot valve 27. This connects the chamber 23 with a return duct 31 allowing the spool 13 to move to the right. When this occurs the passage between ducts 3, 19 is rapidly closed by a band 17'. Fluid now flows through a duct 22 to a non-return valve 32. As pressure builds up the valve opens so that fluid is supplied to the main actuator 35. Movement of the valve 32 to the left also closes the connection between ducts 41, 42 so that fluid flowing to the reservoir from the chamber 23 is throttled by a restriction 30. This damps movement of the spool 13. Further damping is provided when the end of the spool enters a recess 24 and fluid is forced out through a groove 25. To lower the load the selector 56 is moved to the left to energize a solenoid 48 which controls a pilot valve 49. This connects a duct 47 to the reservoir thereby creating a pressure drop across a lowering valve 44 as fluid flows through a restriction 46. This ultimately opens the valve to connect the actuator 35 to drain. This allows fluid to escape slowly from a cylinder 50 through an aperture 51. Figs. 2 and 3 (not shown), illustrate similar circuits in which the pilot valves 27, 49 are operated mechanically or by fluid-pressure.

Abstract: 1529572 Telescopic struts CHRYSLER UNITED KINGDOM Ltd 22 June 1976 [9 July 1975] 28948/75 Heading E2F A telescopic strut, in particular a gas spring strut, having inner 17 and outer 16 members is provided with a latch device in the form of an apertured member 20 through which the strut extends and which is secured against axial movement on member 17; larger 24 and smaller 25 portions of the member 20 being selectively brought into register with the members to allow the passage of either both members or only the inner member 17. As shown the member 20 is plastics and is secured to a U-section arm 18 pivoted to the member 17 so that when the strut is extended the arm falls under its own weight to bring the smaller aperture portion into register and prevent movement down of the member 16. The latch member 20 can be integral with the arm 18 and be plastics coated or an apertured end of the arm could have a plastics insert apertured as described. Reference has been directed by the comptroller to Specification 1415257.

Title: Improvements in or relating to low pressure electric discharge lamps
Inventor: WILLIAMS CHARLES EDINGTON
IPC: H01J61/72
Filed: 1957-09-16
Abstract: 863,468. Discharge lamps. GENERAL ELECTRIC CO. Ltd. Sept. 12, 1958 [Sept. 16, 1957], No. 29062/57. Class 39(1). A low pressure mercury vapour-rare gas fluorescent discharge lamp has a tubular discharge envelope 1 provided at each end with a heatable electrode 2 having a coating of electron emissive material, coated on its inner surface with a layer of fluorescent material, and containing mercury vapour and a rare gas starting filling consisting of neon together with between 10-40, preferably 10-30 or 20% by volume, of argon at a total pressure for the rare gases of 1-4, preferably 2, mms. A shield' may be provided behind each of the two electrodes, as described in Specification 863,467, for restricting the transfer of heat from the space between the electrodes into the space between the shield and the adjacent end of the envelope. In the construction shown in Fig. 1 a circular polished nickel disc 8 is spot-welded to a wire support 9 sealed into the pinch 4 between the electrode leads 3 which pass through holes in the disc and are held out of contact therewith by insulating sleeves 10. Alternatively the disc can be of glass or ceramic and the sleeves omitted. In another construction the discs 8 may be omitted and the envelope provided, behind each of the electrodes, with a constricted region formed by the inward deformation of the envelope wall, as described in Specification 835,144, for restricting the transfer of heat by convection into the ends of the envelope. The constrictions may consist of inwardly directed annular depressions in the envelope wall having a depth such that the internal crosssectional area of the envelope at the deepest part of each depression is about one third of that of the part of the envelope between the electrodes. In another construction both the discs and the constrictions may be omitted and the mercury vapour pressure controlled by operating the lamp in a fitting comprising a primary enclosure and a perforated secondary enclosure for producing a current of air around the end of the lamp envelope as described in Specification 829,441. In another construction the foot-tube at one end of the envelope at least may be formed with a length, and/or an external diameter at least at the end nearer the electrode, which is/are so large that it restricts the transfer of heat from the electrodes and the discharge to the end of the envelope as described in Specification 854,388. Another way of controlling the vapour pressure of the mercury is as described in Specification 828,015 in which the mercury vapour is derived from an amalgam of mercury with another metal or alloy, no free liquid mercury being present. The envelope may be of non-circular cross-section, e.g. oval or kidney-shaped, over the major part of its length to increase light output. When the envelope is of oval cross-section it may be formed with transverse corrugations for increasing its resistance to fracturing under atmospheric pressure as described in Specification 828,604.
Patent GB-463388-A (GB)
Title: A process for improving lubricants, particularly mineral lubricating oils
Filed: 1936-10-26
Abstract: High-molecular fatty acids for improving lubricants are obtained by polymerizing or condensing unsaturated hydrocarbons of low m.w., oxidizing as by air, oxygen, ozone, chromic acid, permanganate, hydrogen peroxide, or nitrogen peroxide, and separating the acids as by saponifying and acidifying.  For example, a 100--300 DEG  C. distillate obtained by the vapour-phase cracking of paraffin wax is polymerized in presence of aluminium chloride, and the viscous oil obtained oxidized at 170 DEG  C. by air, the acids are separated from the crude oxidation product by refluxing with a methyl alcohol solution of caustic soda, adding water, separating the aqueous alcoholic layer, evaporating off the alcohol, extracting oil by pentane, and adding sulphuric acid.ALSO:The oiliness of mineral oil or other lubricants is improved and their corrosiveness reduced by adding high molecular weight oxidation products of polymerized or condensed unsaturated hydrocarbons of low molecular weight.  Up to 10 per cent of the crude oxidation product but preferably of the high mm. acids isolated therefrom is suitable.  In an example, a 100--300 DEG  C. distillate obtained by vapour-phase cracking of paraffin wax is polymerized in presence of aluminium chloride to a highly viscous oil of average m.w. 580 which is oxidized at 170 DEG  C. by air for 216 hr. to produce a viscous oil of average m.w. 810; the acids are extracted by refluxing with a methyl alcohol solution of caustic soda, adding water, separating the aqueous alcoholic layer, evaporating off the alcohol, extracting oil by pentane, and acidifying with sulphuric acid.  The precipitated acids are washed with water, and 3 per cent is added to lubricating-oil.
