IPC: E01C23/02
Filed: 1945-06-26
Abstract: 594,103. Expansion joints. DOCKER, C. E. June 26, 1945, No. 16270. [Class 20 (iv) ] Expansion joints for road and runway surfaces are made by forming a vertical break in the unhardened surface material by means of collapsable shuttering, removing the shuttering when the material has hardened and partly filling the break with a material of low viscosity. As shown in Fig. 6, the shuttering comprises a metal channel 1. supporting rectangular metal.side sections 5 to which are welded L-shaped members 6 forming an interlocking device which limits the extent to which the sides 5 can be forced apart when wedge-shaped members 2 are driven through slots in the channel 1, and a metal capping 7. The shuttering is positioned so that the capping strip 7 is below the level of the finished road or runway and, after spreading the concrete in the normal way, the capping strip 7 with its superimposed layer of concrete is removed and the concrete smoothed over to form a ledge in the walls of the joint, Fig. 7. When the concrete 16 has set, the wedge sections 2 are withdrawn, thus allowing the sides 5 to collapse and to be removed, whereupon the lower portion of the joint is filled with bitumen 13 of a plasticity such that it will easily flow at the lowest temperature. A sealing strip 14 is placed on the ledge formed by the removal of the capping strip 9 and bituminous sealing compound 15 poured on top of this strip.

Abstract: 1,007,454. Discharging boxes from a rollerway; stacking articles on pallets &c. H. GRASVOLL, G. G. MAGNUSSON, and K. I. WEINER. April 30, 1962 [June 6, 1961], No. 16449/62. Headings B8A and B8C. A box 18 conveyed to a discharge point on rollers 17 driven by belt 19, is discharged therefrom to the left by pushers 27 on to rails 15. Pushers 27 are pivotally carried by lever 22 which is oscillated about point 21 by fluid cylinder 25. The box is thus received by stationary rails 15 and is discharged therefrom on to load carrier 34 by the arms 8 of a carrier 7. Carrier 7 is slidable in the vertical direction upon frame 6 which is carried by carriage 3 movable in the horizontal direction by cylinder 10. Carrier 7 therefore under the influence of cylinders 10 and 12 performs an upward movement followed by a leftward movement so that it lifts the box off rails 15 and carries them forwards and downwards to drop them on to load carrier 34, the carrier 7 at the end of the cycle moving rightwards through strippers 16 which serve to retain the box 18 whilst permitting the carrier 7 to return to its point of start. When the load carrier 34 has been fully laden with boxes 18 a pusher 41 operates to push into place a new and empty load carrier 34 thus displacing the loaded carrier 34 for further use. Carrier 7 carries pivoted drivers 50 which aid the carrier to move a box 18 leftwards.

Title: Colour television convergence correction
IPC: H04N9/28
Filed: 1972-04-11
Abstract: 1357684 Cathode-ray tube circuits SINGER CO 11 April 1972 [29 April 1971] 16583/72 Heading H4T In a dynamic convergence connection system for a three-gun colour display tube the correction-signals supplied to the convergence coils are developed from the outputs of sensing means responsive to the scanning deflection currents. Thus the correction is dependent only on the instantaneous positions of the beam shot and is independent of the size, shape or manner of scanning the raster. As shown, sensing means such as resistors in the deflection coils 35 (Fig. 4) provide voltages VNC and VHC proportional to the vertical and horizontal deflection currents, such voltages being squared in amplifiers 37 and 39 and then combined via adjustable attenuators 40 and 43 in summing amplifiers 42 and 45 with the outputs of further attenuators 41, and 43 supplied with the voltages VNC and VHC respectively. Because the Red and Green rasters are oppositely distorted the VHC input to the Green attenuator 43 is inverted in inverting amplifiers 46 and a corner correction is added to the Green and Red scanning amplifiers 45 from an output of a multiplier 47 which multiplies the outputs of multipliers 37, 39 by an appropriate constant. The outputs of the amplifiers 42 and 45 are then supplied to scanning and current drive circuits 51 together with D.C. bias inputs from sources 53 the outputs of the drive circuits providing the correction currents for the convergence coils 55. An additional summer and current drive circuit 51, D.C. bias 53 and convergence coil 55 supplied directly with the VHC voltage is provided for lateral shift of the Blue beam. The invention is stated to be particularly useful in displays used with simulators but is also useful in commercial TV in areas where frequent main voltage changes may cause convergence problems.

Title: Recycling process for the preparation of cyclohexanone oxime
IPC: C07C239/00
Filed: 1975-04-22
Abstract: Cyclohexanone oxime is obtained by circulating an acidic, buffered, aqueous reaction medium between a hydroxylammonium salt synthesis zone and a cyclohexanone oxime synthesis zone. After the circulated liquid is removed from the cyclohexanone oxime synthesis zone, but before it enters the hydroxylammonium salt synthesis zone, it is heated partially and/or regularly in contact with nitrous gases at a temperature of at least 120 DEG C under a pressure of more than 1 at abs. The reaction medium contains an ammonium salt as buffer salt. The hydroxylammonium ions are formed in the synthesis zone in question by catalytic reduction of nitrate ions, while the cyclohexanone oxime is formed in the synthesis zone in question by reacting the above hydroxylammonium ions with cyclohexanone.

Abstract: 1,151,616. Gas and steam turbine plant. C.A. PARSONS & CO. Ltd. April 3, 1968 [April 13, 19671, No. 16997/67. Headings F1G and F1Q. The invention relates to a power plant comprising an assembly of a gas turbine plant and a steam turbine plant. In the embodiment shown the plant comprises an air compressor 1, combustion equipment 2 and a turbine 3 driving the compressor. The gases from the turbine 3 are reheated in reheat combustion chamber 4 and then pass to a useful power turbine 5 which drives a generator 8, the gases from turbine 5 passing to a steam generator 6. The steam from the steam generator 6 is passed through the reheat chamber 4 where it is heated indirectly becoming super-heated, the super-heated steam passing to a steam turbine 7 which is connected to drive the generator 8. The exhaust steam from the turbine or a portion only thereof is passed into the reheat chamber 4 to mix with the combustion gases therein. A throttle means 10 is located at the compressor inlet to throttle the gas flow; the throttle means may be located at another point downstream of the outlet of the first gas turbine. The throttle means is utilized at starting since at this phase of operation there would be no steam for admixture with the combustion gases in the reheat chamber 4 and the turbine 5 would offer too great a flow area.
