Title: Improvements in and relating to melting furnaces
IPC: F27B3/00
Filed: 1936-11-02
Abstract: 473,111. Liquid and gaseous fuel furnaces. HILLEBRAND, P. Nov. 2, 1936, No. 29787. Convention date, Jan. 30. [Class 51 (i)] In a melting furnace with gas and oil firing, the gas and oil burners are spatially separated and so arranged one above the other that the flames from the oil burner or burners 6, 7 are directed immediately over the charge and the flames from the gas burner 5 are located above the oil flames. Similar arrangements of burners are employed at each end of the furnace so that the direction of the flames may be reversed. The oil burners may operate with reducing flames or non-reducing flames. The oil supply to the burners is controlled by varying the stroke of the oil supply pump.

The switches may be remotely controlled by manual switches such as BS<1> installed adjacent to the respective mechanical control elements S<1>, S<2>. Dimmers may be used in association with the changeover switches to prevent undesired sudden changes in illumination. Direct or rectified current may be used for the operating circuits of the change-over switches, to avoid noise.

The beta-thioethers and esters are all of the general formula ROOCCH2CH2S-X in which R is hydrogen or an alkyl or cycloalkyl radical and X is a hydrocarbon group, an oxygenated-hydrocarbon group, a sulphur-hydrocarbon group, or a sulphur and oxygenated-hydrocarbon group, or a sulphur- and nitrogen-hydrocarbon group.  Exemplified thio-compounds are 3-benzothiazyl mercaptopropionic acid, and dilauryl and distearyl beta-thiodipropionate.  The stabilizers may be added to the polymers in the solid or molten state, or to a solution or suspension of the polymer in an organic solvent.  The beta-thioethers and thioesters are preferable used in conjunction with propionate-improvers, i.e. lecithin, glycerol, tyrosine, citric acid and/or tartaric acid, or the synergistic combinations described and named in U.S.A.

Abstract: 852,543. Magnetic storage matrices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 1, 1957 [Oct. 4, 1956], No. 30699/57. Class 40 (9). [Also in Group XVII] A tubular needle 88 is used to thread a wire 90 through a row of cores 42 in a magnetic matrix. The needle is fed into the cores by hand-operated rollers 100, 102. When the needle leaves the rollers 100, 102 it is held by a braking roller 112 operated by a handle 118 and wire is driven by rollers 100, 102 through the needle as far as clamp 48 by which it is held. The needle is then withdrawn by rollers 112, 100 and 102 and the wire is cut by a knife blade 132. The cores of a 32 x 32 matrix are held by suction in a jig 38 which fits the top of a vacuum chamber 32 on a turntable 16. The turntable has two notches 22 which co-operate with a detent 24 to fix the turntable in either of two positions in which the rows or the columns are presented to a set of 32 needles for threading. The needles slide in parallel grooves 86 in a support 82 pivoted at 60 and are covered by a transparent plate 92. A screw 96 is used to adjust the level at which the needles enter the cores. The wires are stored on reels 72 which are braked by an adjustable shoe 120. The jig 38 may be formed with parallel grooves 46 to take the wires in one direction at a lower level than the wires in the direction at right angles to the grooves.

Semi-conductor devices are tested for surface electrical phenomena and inner structural defects by scanning the device in a raster scan using a Nipkow disc and applying the photo-current produced to the vertical deflection of an oscilloscope to which is applied a raster synchronized with the scanning of the semi-conductor device. The Nipkow disc produces line and frame sync. pulses. The line pulses trigger the line scans and step on a staircase generator which provides the vertical deflection signal and the frame pulse returns the staircase generator to zero. The display reveals inter alia local avalanche breakdown.

Abstract: 936,343. Laminates. BAYERISCHE MOTOREN WERKE A.G. Sept. 10, 1959, No. 30963/59. Drawings to Specification. Class 140. [Also in Groups XXII and XXXII] A resilient packing between opposed surfaces of sheet metal is produced by positioning between the surfaces a strip of plastically deformable bonding material embodying a swelling or foaming agent, the strip being adapted to be expanded and transformed from the plastic to the elastic state by curing, and then curing the strip to expand and bond it in situ to one or both of the surfaces. If one surface is to remain unbonded it is first treated with a parting agent, e.g. oil, grease or talc. The bonding material may be a vulcanizable rubber. Sheet metal structures may be secured to one another, e.g. by welding, at points spaced from one another, e.g. at the extremities of their surfaces, and have resilient packing formed by the above method extending substantially between these points. The resilient packing may be a strip disposed in a U-shaped recess in one of the sheets. When a structure such as a motor-vehicle body is being built and provided with resilient packing by the above method, the vulcanization may take place during the heating of the structure for another purpose, e.g. after painting.

Title: Dual-line lubrication systems
IPC: F16N25/04
Filed: 1957-10-04
Abstract: 867,584. Force-feed lubricating. DE LIMON HULME & CO. Oct. 4, 1957 [Nov. 7, 1956], No. 31119/57. Class 12 (3). In a dual-line lubrication system, means are provided for relieving pressure in both feed lines A, B simultaneously during a rest interval in order to reduce leakage from them through the feeders V. The system comprises a five connection, four position rotary valve 2 which in the position shown, connects the feed line A with a relief valve R 2  and the feed line B with a pump PF. After actuating the feeders V and thereby supplying lubricant to the righthand delivery lines L, the rise in pressure actuates a ram 1 which rotates the valve through 90 degrees and thus reverses the connections to the feed lines A and B. Lubricant is then delivered to the left-hand delivery lines L and the subsequent rise in pressure in line A actuates the ram 1 which rotates the valve 2 through a further 90 degrees, whereby both lines A and B are put in communication with an outlet R 1 . Also a projection 3 on the plug 2 actuates a switch S which sets a timer T to stop the pump for a predetermined rest interval. On re-starting, the rise in pressure in the pump outlet actuates the ram 1 which rotates the valve 2 through another 90 degrees, whereby line A is re-connected with the pump and the line B is connected with the outlet R 1 . A further pressure rise ensues and the ram 1 rotates the valve through yet another 90 degrees. Non-return valves may be located in the left-hand delivery lines L.

Filed: 1972-07-04
Abstract: 1369335 Electrostatic precipitators AMERICAN STANDARD Inc 4 July 1972 [2 Nov 1971] 31316/72 Heading B2J An electrostatic precipitator comprises two apertured plates P1, P2 between which is located an apertured plate K of dielectric material, e.g. fibreglass or plastics material. When a direct or alternating electric field is established between the plates P1, P2, which may be metallic, electrical charges are induced on the opposite surfaces of the plate K whereby charged particles in a fluid medium passing through the apertures may be attracted to and collected by the plates. The size of the apertures and distance between the plates are such that vortex patterns are formed as the fluid flows through the apertures so that the charged particles are slowed up to facilitate their attraction by the plates. Two or more electric plates may be located between the metallic plates. An embodiment comprising a first plurality of interconnected metallic plates, a second plurality of such plates and a plurality of dielectric plates is described with reference to Fig. 3 (not shown). The described precipitator may be used as an add-on unit coupled to a conventional precipitator.
