Title: Improvements relating to resilient load supporting assemblies
IPC: F16F3/087
Filed: 1949-09-28
Abstract: 665,533. Resilient mountings. S.A.G.A. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI. Sept. 28, 1949 [Sept. 28, 1948], No. 24950/49. Class 108(iii) [Also in Group XXXIV] The invention relates to resilient mountings of the kind comprising two sets of elastic elements 4, 6, Fig. 1, each of which is connected at one end to a rigid supported member 3 and at the other end to a supporting member in the form of a rigid frame 5 so that the 'elements work in parallel and under shear-flexion stress. According to the invention the elements of one set are internested with the elements of the other set so as to reduce the overall dimensions of the mounting in a direction perpendicular to that in which applied load P acts. The invention may be applied to the mounting of rims on the hubs of wheels (see Group XXXIV). According to the Specification as open to inspection under Sec. 91, the right-hand side of the frame 5 may be separate from the left-hand side. The latter is not bolted to the base 5a, but is adapted to receive the load P. The member 3 is thus floating and the elements 4, 6 work in seriesparallel. In another construction, Fig. 4 (Cancelled) (not shown), the elements are in the form of annular rings working in compression and are disposed in series between rigid plates. Alternate plates are of dished formation and an element of reduced diameter is nested in each dished portion. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to grating monochromators
Inventor: MARTIN ALBERT EDWARD
IPC: G01J3/18
Filed: 1958-08-05
Abstract: 861,259. Monochromators. PARSONS & CO. Ltd., Sir H. G. July 27, 1959 [Aug. 5, 1958), No. 25008/58. Class 97(1) The dispersive element of a "blazed" grating monochromator comprises a plane grating having a plurality of areas, each area being ruled with equi-spaced parallel grooves, the groove spacings for the separate areas being equal or simple multiples of one another with all the grooves parallel, and a different groove angle being associated with each area. Fig. 2 shows the grooves of such an echelette grating in transverse section, the longer "blazed" surface of the sawtooth groove being so inclined with respect to the incident beam as to produce spectral reflection in the direction of the desired first order diffraction maximum. The intensity drops to either side of the "blaze" wavelength and to extend the spectral range over which high intensity is obtained, an adjacent region of the grating is "blazed" for a different wavelength. The grating may be rotatable about an axis through its mounting, or about an external axis O as in Figs. 4a and 4b, different portions of the grating intercepting the incident beam BD on rotation of the grating to give wavelength selection with fairly even intensity. A particular wavelength will be present in various orders if the groove spacings in the different areas are in simple ratio. Alternatively, all groove spacings may be equal, varying only in blaze angle in the different areas. If the groove spacings in different areas are not exactly equal or in exact simple ratio, adjacent areas may be tilted slightly relative to one another to give diffraction maxima in the same direction for a wavelength intermediate to the blaze wavelengths associated with the two areas. For other wavelengths, the rotation of the grating will cause the energy contribution from one area to predominate, and the discrepancy is reduced.

Abstract: 823,612. Semi-conductors. GENERAL ELECTRIC CO. Ltd. Aug. 16, 1957 [Aug. 17, 1956], No. 25283/56. Class 37. A junction in a semiconductor is formed by applying to the surface of the solid semi-conductor body a readily oxidizable molten material consisting at least partly of a substance capable of acting in the semi-conductor as a significant impurity and of dissolving in the body, the molten material being applied so as to break a clean surface of the molten material on to the surface of the body and subsequently solidifying the molten material in such a way that a solid layer of the semi-conductor is deposited, contiguous with the remainder of the body, from the molten material. The semi-conductor material, e.g. germanium, is placed as a wafer 3 in a cup 2 and held by a tube 4 fitting internally in the cup and supporting a block 5 having a cavity 7 communicating with a shaped bore 8, 9. A rod 10 may be lowered into the cavity 7 to close the bore 8 from the cavity. The jig 2-4 is located in a glass enclosure 12 through which hydrogen may be circulated and provided with a heater 13. With the bore 8 shut, indium is placed in the cavity 7 and the jig heated to 100‹ C. for one hour to degas the jig and its temperature is then raised to 400‹ C. in 15 minutes and held at that point for 45 minutes. The indium melts and at the end of this period the rod 10 is raised and the molten indium flows into the bore 8 and drops on to the germanium wafer 3 spreading over the whole of its exposed area and forming a hemispherical blob. Holes 9 permit the displacement of hydrogen as the indium flows. After the release of the indium the temperature is held at 400‹ C. for a further 5 minutes during which the molten indium dissolves part of the germanium surface, on cooling, resolidification takes place forming the required junction.

Title: Improvements in or relating to evaporating and distilling plants of the vapour compression type
IPC: B01D1/28
Filed: 1946-08-26
Abstract: A steam-jet compressor and a turbo-compressor are connected in series to an evaporator. or to at least one stage of a multi-stage evaporator, the two compressors being arranged to effect double compression of the vapour and to deliver the compressed vapour, together with the steam, to the heating element of the evaporator or stage.  Fig. 2 shows a two-stage plant with a steam-jet compressor D interposed between the two evaporators VI and V2, the second of which works at a lower pressure than the first.  The vapour from evaporator V2 is compressed by the steam-jet compressor and delivered, together with the steam and also the vapour from evaporator V1, to turbo-compressor TK wherein the vapour mixture is compressed and then supplied to heating elements H1 and H2.  A four-stage plant, utilizing three steam-jet compressors and one or three turbo-compressors, is also described. The plant may be adjusted by regulating the quantity of vapour supplied to the heating element; this being effected by a heat-exchanger interposed ahead of the first compressor, as in Fig. 6, or between the compressors as in Fig. 5. In Fig. 6, the vapour not needed for heat requirements is condensed in heat-exchanger A2, the quantity being regulated by valve E which admits cooling medium to the heat-exchanger.  In Fig. 5, the heat-exchanger A acts as a preliminary evaporator, for the liquid to be evaporated acts as the coolant therein; regulation, in this case, being effected by vapour-escape valve E.  The plant may be automatically regulated in dependence upon temperature, pressure, quantity or concentration of the liquid to be evaporated. <PICT:0616329/III/1> <PICT:0616329/III/2> <PICT:0616329/III/3>
