Title: Method for the manufacturing of circular bottom plates for sheet metal receptacles
IPC: B21D51/18
Filed: 1923-03-13
Abstract: 195,067. Singewald, M. March 18, 1922, [Convention date]. Metal casks: heads.- For the production of circular bottoms with a minimum of waste, sheet metal strips a, Fig. 1, with reinforcing longitudinal corrugations s, are cut into triangular pieces d which are joined together, as by welding, to form the solid bottom shown in Fig. 3. If an absolute circular form is necessary the strips m only are wasted. In an alternative method trapezoidal pieces are cut out from the strip a, in which case the bottom when joined up will have a central opening.

Filed: 1960-03-08
Abstract: 881,642. Jointing; soldering; brazing. GRAMES. March 8, 1960 [March 17, 1959], No. 8084/60. Class 83 (4). A method of jointing hollow metal sectional members 1, 2 by means of a metal gusset 3 engaged in the adjacent ends of adjacent members and by interposed resin adhesive or by soldering or brazing, is characterized in that there is added to the gusset 3 an element 5 which is inserted between the ends of the members so as to be unaffected by the screening effect of the members when heat is applied by means of a high-frequency induction current to the ends of the sectional members and to said element, the latter, by conduction, bringing the gusset to the bonding temperature simultaneously with the sectional members. The element 5 has a forked profile and engages in a groove 4 in three sides of the gusset 3 and the outer periphery of the element corresponds to the outer profile of the sectional members. In a modification the element is withdrawn after the bonding.

Title: Arrangement for the complex balance of telephone cables by means of screened balancing elements
IPC: H01G2/00
Filed: 1950-03-31
Abstract: 680,150. Preventing inductive disturbance. SUDDEUTSCHE APPARATE-FABRIK GES. March 31, 1950 [April 1, 1949], No. 8128/50. Class 40 (iv). The anti-crosstalk cable balancing elements C, R, Fig. 2, are doubly screened, the inner screens Sc, SR being connected to the respective elements and the outer screen Sa being connected to earth. By this means the circuit couplings are made less dependent upon small movements of the elements within their casings and in particular eliminating the effect of the stray capacity between earth and the connection between C and R. The additional capacities C1, C2 between the inner and outer screens may be compensated by additional capacities connected between other legs of the circuits being balanced and earth. Fig. 5 shows an earthed case 14 forming the outer screen, the case being divided into compartments for containing the capacity C and resistance R. These elements are connected by the central core of a doubly-screened cable, the inner screen of which is connected to a metal shell surrounding the condenser C. This screen is also connected to the leg 1 of the cable being balanced. The metal shell surrounding the resistor R is connected via a separate screened lead to the leg 2 of the cable being balanced. The elements C or R and their metal shells are sealed into protective ceramic shells 12.

Abstract: 375,290. Altimeters. BARNES, J. W., Royal Aircraft Establishment, South Farnborough, Hampshire. March 18, 1931, No. 8283. [Class 106 (ii).] Comprises an altimeter in which the pointer has one movement due to atmospheric pressure and a second one due to temperature the pointer indicating height corrected for temperature. A disc or sector 2, arranged to be moved by hand about an axis 3 for variation of ground barometric pressure, is provided with a spiral or curved height scale 1. An arm 4 behind the sector is moved about the axes 3 by an aneroid, (not shown). A pointer 5 is pivoted to the arm 4 and is moved angularly relative thereto by a bi-metallic strip or other temperature affected means. As shown, an arm 8 rigid with the pointer is connected by a chain 10 to a drum 9 on the axis 3, the drum being rocked by a thermometer of the Mercury Bourdon tube type, (not shown). Alternatively gearing may transmit this motion. In the example shown the altimeter is combined with an air speed indicator which rotates a disc 12 carrying a logarithmic scale 11 in front of the dial 2 about the axis 3. The pointer 5 indicates on this scale air-speed corrected for changes in air density. The uncorrected air-speed is indicated by a pointer 13.

Abstract: 409,123. Moulding synthetic resins &c. in stationary-mould machines. EATON, M. M., 18, Brearley Street, Birmingham. March 20, 1933, No. 8310. [Class 87 (ii).] In the moulding and curing of synthetic resin or other plastic material, the moulds 1 are superposed in a press chamber heated by steam pipes 7 or other means, and are compressed intermittently by a ram 3 while supported against a fixed abutment 2, the bottom mould being delivered laterally to a conveyer 25 and an additional freshly-charged mould being fed to the top of the pile after each stroke of the ram. The bottom mould falls into a recess in a sliding plate 8 which is reciprocated by a crank 12 and during its movement also operates the ram through the medium of the bell-crank lever 19 and the feed slide 27 through the linkage 28, 29, 30. A compression spring 23 yields when the ram is prevented from making its full stroke before the powder in the top mould has been plasticised by the heat and automatically lowers the ram as the plasticising proceeds. The moulds for feeding into the apparatus preferably are stored in a heated magazine 26. The moulds are all made to standard exterior dimensions, but a variety of articles may be moulded simultaneously.

Abstract: 654,642. Gravity separation apparatus. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. March 27, 1947, No. 8333. Convention date, April 9, 1946. [Class 46] Liquid-separating apparatus comprises a vessel containing a number of substantially horizontal parallel tubes through which the mixture is passed, in which each tube is imperforate over substantially its whole length, but at or near to its discharge end has separate outlets for the two liquids, these outlets being spaced apart a short distance along the length of the tube and opening into a common discharge chamber. Preferably the outlet for the major constituent of the mixture is further along the tube in the direction of flow than the outlet for the minor constituent. Where the heavier liquid issues through the first outlet the upper tubes are preferably arranged to terminate level with or short of the lower tubes ; conversely where the lighter liquid flows out from the first outlets, the lower tubes should terminate level with or short of the upper tubes, to prevent re-mixing. A vessel 1, Fig. 1, has a partition 3 to which tubes 2 are attached, the tubes having near their open ends 9 first-outlets 8 which being directed partly downwards are intended for the escape of the heavier liquid assumed to be the minor constituent. The tubes are preferably arranged as in Fig. 4 to assist the sinking of the heavier liquid, which leaves by the outlet 6. When the lighter liquid is the minor constituent the firstoutlets are directed partly upwards for its escape as in Fig. 3, in which a part of the wall of each tube is bent upwards to form a guide and nesting lip 10 as well as providing an opening 8a. Fig. 5 shows an alternative arrangement, which is inverted when the heavier liquid is the major constituent. The separator may be used in solvent extraction processes or for the separation of mineral oil emulsions, e.g. those resulting from acid treatments.
