Title: Drive gear mechanism
Filed: 1945-12-19
Abstract: 605,303. Differential gearing. TRIGGS, W. W. (Koehring Co.). Dec. 19, 1945, No. 34447. [Class 80 (ii)] In differential gearing for vehicles and other purposes, planet pinions 4, in a carrier, drive a sun pinion 7 and an internally-toothed annulus 6, the members 6, 7 being connected to the parts to be driven and being interconnected by friction means so that torque will be transmitted to one member even if the other member is free from resistance. As shown, for a vehicle, one wheel 13 is driven from the annulus 6 by chain gearing 15 and the other wheel 16 is driven from the sun 7 through shaft 9 and chain gearing 15a. A spider 10 on the shaft 9 carries a friction band 11 which is expanded by a spring 11a into frictional contact with the interior of a drum 12 fixed to the annulus 6. The normal vehicle brakes A act on the periphery of the annulus 6 and on a drum 19 fixed to the shaft 9.

Title: Process for the manufacture of concentrated phosphoric acid
IPC: C01B25/22
Filed: 1934-12-05
Abstract: <PICT:0453582/III/1> Phosphoric acid is obtained by reacting a calcium phosphate with sulphuric acid in the presence of phosphoric acid under such conditions of temperature and concentration as to yield crystals of hydrated calcium sulphate.  Calcium phosphate is fed by a conveyer 3 from a silo 2 into a vat 1 provided with a turbostirrer 4, phosphoric acid also being supplied through a pipe 19.  The resulting solution, relatively free from particles of undissolved phosphate flows through a pipe 5 into a reaction vat 6. This vat is fed with concentrated sulphuric acid from a tank 17 and washing liquors from a tank 16 and is stirred by means of a turbo-stirrer 8, through the return tube 7 of which the reactants enter.  A heating coil 9 maintains a temperature of 90--100 DEG  C. in the vat 6.  The larger crystals of calcium sulphate are raised from the bottom of the vat 6 by means of a pump, bucket conveyer or emulsifier 10 into a stirred decanter 12.  Phosphoric acid freed from calcium sulphate returns to the vat 1 via the pipe 19.  Preferably, a slight return of phosphoric acid is effected through a pipe 21 from a reservoir 20 in order to remove any unattacked phosphate which is also made to pass through the pipe 19.  The calcium sulphate crystals are sent periodically into a washer 13 and the crystals accumulating in this washer serve as a filter for the freshly produced phosphoric acid which has accumulated by overflow in a vat 18.  Concentrated phosphoric acid flows into a vat 14.  Washing of the calcium sulphate in the washer 13 is effected by hot water or steam or both, the washing liquors passing into a tank 15 and being pumped therefrom into the tank 16.  The hydrated calcium sulphate may be dried by slight heating in order to give a plaster.  Each of the vats 1 and 6 may be replaced by two or more vats arranged in series.

Title: Weighing device for ascertaining the weight of moving loads such as vehicles, crane loads or the like
IPC: G01G19/04
Filed: 1969-07-11
Abstract: 1,235,267. Weighing electrically. CARL SCHENCK MASCHINENFABRIK G.m.b.H. July 11, 1969 [July 12, 1968], No.35080/69. Heading G1N. A moving load, such as a railway wagon or crane load, is weighed in the presence of disturbing oscillations by sensing and storing at least two successive extreme values (one maximum and one minimum) of the load cell output signal and combining the extreme values to give an indication of the weight. If damping can be neglected, two successive extreme values are merely added to give a signal proportional to the weight. If damping is allowed for, three successive extreme values Y 1 , Y 2 , Y 3  are sensed and stored and a signal proportional to the weight is derived by dividing the difference between Y 1  times Y 3  and the square of Y 2  by Y 1  + Y 3  - 2Y 2 .

Abstract: 1,169,642. Laminated safety-glass. FORD MOTOR CO. Ltd. 2 Aug., 1967 [12 Oct., 1966], No. 35505/67. Heading B5N. In laminated safety glass having a plastics layer interposed between two sheets of glass, at least one of the latter is of float glass and is arranged with its face that has been in contact with the bath during its formation exposed and with its other face, which may have surface irregularities, adjacent to the plastics layer. As a result of the lamination process, the plastics which has a refractive index similar to that of the glass, e.g. polyvinyl butyral, fills the surface irregularities. The other sheet of glass may also be of float glass or it may be of plate glass. The sheets of glass may be bent prior to being laminated so as to form a windscreen when laminated by heat and pressure. The bloom on the face of the float glass to be exposed in the laminate may be reduced by polishing or by reducing the degree of oxidation of the tin in the float chamber during the manufacture of the float glass.

Abstract: 1302510 Making shadow masks TOKYO SHIBAURA ELECTRIC CO Ltd 29 July 1971 [31 July 1970 (2)] 35630/71 Heading B3A [Also in Division H1] A shadow mask is supported by a rectangular frame formed of a strip of L-shaped cross-section, the angle between the arms of the L exceeding 90 degrees at the corners and increasing towards the centres of each side. Preferably the width of the side wall of the frame also increases from the corners towards the centres of each side. The frame is initially plane and then bent to conform to the curvature of the mask portion, and strains produced in this process are reduced by these features. In one arrangement, Figs. 2-6 (not shown), the strip is bent sharply into its L shape, and the angle α by which the L exceeds 90 degrees may vary from 5-15 degrees at the corners to 10-45 degrees at the centres of the short sides and to 15-55 degrees at the centres of the long sides, preferred values being 5, 10 and 30 degrees, respectively. In another arrangement, Figs. 8-12 (not shown), the angle of the L is curved to a radius R 1  of one to three times the thickness of the strip and the free edge is curved in the opposite direction to a radius R 2  equal to 15R 1 . The angle α (as defined above) in this ease refers to the tangent at the edge of the strip and varies from 5-7 degrees at the corners to 10-30 degrees at the centres of the short sides and to 15-45 degrees at the centres of the long sides. If the mask is to be etched to increase the size of its apertures after processing the screen of the tube, apertures may be provided in the edge of the frame at each corner to allow the etching fluid to drain properly (Fig. 7, not shown). Making shadow masks.-A metal strip is bent longitudinally in a machine to the generally L-shaped section described above, and then bent into a frame with the ends welded together. The frame is pressed to the curvature of the mask to be fitted on it and may be heated to remove strain. Subsequently the mask portion is fitted over the frame and welded to it. The manufacture of the modified construction with the curved edges (Figs. 8-12, not shown) is similar except that the grooves which form the edges and the apertures for draining etching fluid are formed before the metal strip is bent into the L shape.
