Abstract: 399,011. Road-vehicle opening-tops. PAULIN, G. A., 61, Avenue Pierre-Larousse, Malakoff, Seine, France. Sept. 8, 1932, No. 25068. Convention date, Dec. 19, 1931. [Class 108 (i).] In motor vehicles having a movable rigid cover hinged upon a spindle and adapted to be stowed away into a rear receptacle, the opening of the receptacle, the displacement of the rigid cover and the closing of the receptacle are effected successively by means of a single member controlled by the driver. As shown in Figs. 1 and 2, the hood or cover comprises two portions 1, 2 hinged to one another and pivoted at 10 to the vehicle body. The cover is folded together and turned back into a receptacle 21 by means of a spindle 14 having a worm thereon actuating a worm wheel 12 on the pivot shaft 10. Rotation of this pivot shaft 10 also folds the two parts of the cover together by means of a chain 8, 9, arm 7 and links 5, 6. The spindle 14 is rotated from a crank 20 at the driver's seat by means of a cable 16 passing roung pulleys 15, 17. The lid of the receptacle 21 is opened to admit the folded cover and closed when it is in position by means of the same spindle 14 which drives a screw 24 actuating a slidable nut 25. Racks on this nut 25 rotate one or other of two pinions according to the direction of travel and cause a double armed rocker lever 33 to open or close the lid by means of a cord 32. Figs. 7 and 9 show an arrangement in which the top or cover is in one piece hinged to the body. The top and the lid of the receptacle are both operated by a crank 20 through a shaft 39 which by means of a worm 40, worm wheel 41, cords and chain 44 cause the top to be opened or closed while the lid of the receptacle is operated bv cords from a double-armed lever 54 mounted on a pinion 52 which is rotated in one direction or the other by means of the teeth 49a on nuts 49 which traverse two screws 46, 48, one 46 being formed on the shaft 39.

Title: Electrical circuits for providing high power pulses
IPC: H03K3/57
Filed: 1966-06-08
Abstract: 1,131,561. Pulse generators. SPERRY RAND CORP. 8 June, 1966 [29 June, 1965], No. 25502/66. Heading H3T. In a pulse generator of the type in which a high voltage energy storage element is first charged from a low-voltage energy storage element and then discharged into a load so as to generate a pulse, additional storage elements are provided in such a manner that the width of the output pulse can be changed by switching at low voltage level. As shown, the low voltage storage elements are provided by capacitors 4, 5 and are charged from a D.C. supply 1 via inductor 3, bias windings 6, 7, 8 on saturable transformers 9, 10, 11, inductors 14, 16, 19 and the primary winding 18 of transformer 10. Transformers 9, 10 are thus saturated in a negative direction and transformer 11 in a positive direction. When siliconcontrolled rectifier (SCR) 24 is triggered to generate a pulse, capacitor 5 is discharged via winding 18, bringing transformer 10 out of saturation and charging the high voltage storage capacitor 31. This action drives transformer 9 further into saturation isolating the load from the charging circuit. Current in winding 26 brings transformer 11 out of saturation. Upon completion of the discharge of capacitor 5 into capacitor 31, transformers 9, 11 become saturated in the positive direction and transformer 9 in the negative direction, the saturation of transformer 10 presenting a low impedance to capacitor 31 and initiating its discharge through winding 27 of the output transformer 9, initiating the output pulse. When capacitor 31 is discharged, transformers 9, 11 remain unsaturated until they are reset by further charging current in bias windings 6, 7, 8. An output pulse of different width may be provided by changing the settings of switches 21 . . . 23 which select a different low voltage energy storage capacitor 4 and reverse the direction of bias windings 7, 8, thus selecting transformer 11 which couples the delay network 25 into circuit for use as a high-voltage energy storage element. The transformer 10 or 11 not in use remains in an unsaturated (high impedance) condition for the entire interval between the completion of charging of capacitor 4 or 5 and the final discharging of capacitor 31.

Title: Improvements in and apparatus for the continuous oxidation of normal butane in the liquid phase
IPC: C07C51/215
Filed: 1959-07-28
Abstract: Normal butane is continuously oxidised to a product comprising mainly acetic acid in the liquid phase containing a solvent and from 3 to 20% by weight of n-butane, at elevated temperatures and under a pressure of from 20 to 100 atoms, with an oxygen-containing gas in such an amount that, after removal of the fraction condensable at temperatures down to about 0 DEG C, the presence of a maximum of 7%, preferably of 1-2%, of oxygen in the waste gas is ensured, wherein n-butane and oxygen-containing gas are supplied to the bottom of an oxidation zone of an oxidation chamber and where the reaction mixture ascending in said zone is allowed to circulate and descend through a return zone.  The return zone may be in the form of an external tube or the oxidation chamber may be divided into oxidation and return zones (which may be further subdivided) by means of vertical partitions.  For maximum acetic acid production, the n-butane should be of at least 90% purity and should preferably contain not more than 5% isobutane or 2% butylenes.  The solvent is preferably the oxidation product formed by the reaction.  The necessary butane content may be ensured by working with a circulating amount of butane such that only about 3-10% reacts in a single throughput. Temperatures of 140-210 DEG C. may be used.  Circulation of liquid may be promoted by a pump.  The heat of the reaction may be removed by using a cooling medium or by the evaporation of part of the unreacted butane and the oxidation products.  The cooling of the gases leaving the apparatus is preferably effected in a plurality of stages using cooling water and then cooling brine.  The butane phase of the condensate is replenished and returned to the reaction chamber and sufficient of the acetic acid phase to maintain a constant level is also returned.  The oxidation products in Examples comprise, in addition to acetic acid, formic acid, propionic acid, butyric acid, methyl formate, methylacetate, ethylacetate, acetaldehyde, acetone and methylethyl ketone.ALSO:<PICT:0865747/III/1> A vertical oxidation chamber for treating liquids with a gaseous oxidising agent is divided vertically into zones which are in communication above the bottom of the chamber and below the level of the liquid phase so that the liquid phase may circulate freely through the zones.  Circulation may be promoted by pumping if desired.  In Fig. 2, 1 is an oxidation zone, 2 a return zone, 3 the supply for the oxidation gas, 4 the supply for liquid to be oxidised, 5 the level of liquid, 6 the outlet for waste gas, 7 the supply pipe for solvent and 8 a jacket for heating or cooling medium.  Figs. 1 and 3 (not shown) respectively illustrate recycling the liquid outside the reaction zone and the use of a single cylindrical baffle: in neither case is a heating or cooling jacket shown.

Abstract: 1,120,622. Synchronizing A.C. supplies. LONDON ELECTRICITY BOARD, and D. C. GREEN. 21 Sept., 1965 [23 June, 1964], No. 26872/64. Heading H2H. [Also in Division G1] The phase difference between two separate alternating current supplies at stations A, B which are connected to different generating plant A<SP>1</SP>, B<SP>1</SP> is measured at a remote point 2 by establishing separate communication paths 3, 4 such as voice frequency channels, between point 2 and each station A, B. Apparatus 5, 6 is provided for extracting similarly timed pulses from the supplies at stations A, B. The pulse signals from both paths 3, 4 are received at point 2 by a cathode ray oscilloscope 7 having a circular time base. A pulse generator 8 having a repetition rate locked to the time base of oscilloscope 7 but adjustable in phase relative thereto is arranged so that pulses may be simultaneously transmitted over each path 3, 4 to trigger a return signal from each station A, B back along the path. A transmitted pulse from generator 8 is shown on the oscilloscope trace at 10, Fig. 2, the pulse reflected from A at 11 and that reflected from B at 12. The circumferential distance between the reflected pulses 11, 12 is an indication of twice the delay time different. A delay network 9 is switched into path 3 and adjusted until reflected pulses 11, 12 coincide so that paths 3, 4 have the same delay time. The apparatus is then prepared to display phase information along paths 3, 4 from stations A, B, the trace of the oscilloscope Fig. 4 (not shown), representing the phase relationship of the voltage vectors at stations A, B. In a modification (not shown) each path 3, 4 comprises two channels arranged to operate in the same medium at different frequencies. At each station A, B the channels of each path are interconnected by filters and by a pulse modulator/demodulator unit. Pulses produced by generator 8 are transmitted over one of the channels of each path and return pulses triggered back along the other channel of each path.
