Title: Improvements in or relating to auxilliary steering mechanism for vehicles
IPC: B62D11/10
Filed: 1958-07-17
Abstract: 842.814. Steering vehicles by braking axles. THOMAS, G. A. July 17, 1958 [July 19, 1957] No. 23001/58. Classes 79(2) and 79(4). A tractor with steerable front wheels 9 Fig. 2 is provided with auxiliary steering brakes 5 on the differentially driven rear wheels, actuated by transverse movements relative to the chassis of a front wheel carrier or axle 12 caused by ground reaction. In one example the front wheels 9 are mounted by stub axles 10 on the axle 12 which is swingably mounted between brackets 17, 18 bolted to the underside of the main frame. The axle 12 comprises bracing members 24 welded to a longitudinal tube 23 containing bearings 22 for a cranked shaft 21 having trunnions 19, 20 mounted in the bracket 17, 18. Brake cylinders 33 Fig. 6 mounted on the front bracket 17 and connected to the independent rear wheel brakes are actuated by transverse movements of the axle 12 through an extension 25 of the shaft 21 which engages one or other of plates 27 pivoted to the trunnion 19 and coupled to the brake cylinders through connecting rods 32. The auxiliary steering may be rendered inoperative by a flexible cable system 35 which may be set by a knurled nut 39 on the vehicle switchboard 38 to hold the plates 27 in rigid engagement with a fixed stop 26. In a modification the system is adapted for cable operated brakes 41 Fig. 9, the projection 25 pivoting a cam plate 47 about the fixed pivot 19, the cables 41 being cross-connected to arms 43 of the cam plate 47. A spring loaded roller 48 provides stabilising means for holding the cam 47 in the central inoperative position. In a further modification the axle 12 Fig. 10 is attached to a sprung frame 62 by shackles 69, the axle 12 having slots 68 to permit transverse swinging of the shackles 69 so that the brake cylinders 33 may be actuated by a projection 71 on the axle 12.

Title: Improvements in electric oscillatory circuits comprising active networks
IPC: G01R29/22
Filed: 1945-09-06
Abstract: 597,439. Valve generating circuits. GENERAL ELECTRIC CO., Ltd., and BIGGS, A. J. Sept. 6, 1945, No. 23017. [Class 40 (v)] [Also in Group XXXVI] An oscillatory circuit having in effective negative resistance substantially independent of frequency and adapted to measure the dynamic resistance of passive oscillatory networks, comprises an input valve with the primary winding of a phase reversing transformer in its cathode circuit, the secondary winding being tuned and coupled to the control grid of a second valve which has its anode coupled back to the control grid of the first valve by an impedance of the same type as the effective anode load of the second valve. In operation, networks of unknown dynamic resistance are compared with a calibrated test network TC of the type described in Specification 597,430 in which variable capacitor C5 determines the dynamic resistance. The unknown network is connected across terminals 3, 4 and capacitor CO is adjusted to tune the secondary winding T2 to the operating frequency as shown by a maximum reading on microammeter M. Ganged switches S1, 82, S3 are then changed over and capacitor C5 is adjusted to produce the same meter reading, when the calibration indicates the dynamic resistance of the unknown network. Transformers TP are similar and capacitor C6 is pre-set to tune winding P2 to the operating frequency of the test network. Alternatively, switches S2, S3 may be omitted when capacitor C0 is readjusted to resonance with the test network after switch S1 has been operated. Transformers P, T are preferably step-up transformers with dust iron cores and resistors R1, R4 are inserted in series with the primary windings to eliminate the effect of grid-cathode capacity in valve V1 at high-frequencies. Circuit conditions are calculated for producing an effective negative resistance which is independent of frequency.

Abstract: 858,755. Locking devices. ELECTRICITE DE FRANCE-SERVICE NATIONAL. July 22, 1957 [April 30, 1957], No. 23190/57. Class 80 (3). [Also in Group XXV] A device for locking a load support 1 against downward movement in a vertical or nearly vertical channel 2, comprises one or more gravity-loaded locking members 3 pivoted to the support 1, each member having at least two arms 7, 8 which co-operate with at least two grooves 11, 12 in the wall of the channel in such a way that both the application and release of the locking is controlled by movement of the support 1 itself. In the position shown in Fig. 2, the support 1 is locked against downward movement by the arms 7, 8, but may be raised freely. The locking is released by raising the support 1 until, under the action of gravity, the arm 7 enters the groove 12 (position 3a, Fig. 4), and then lowering the support so that the arms 7, 8 successively engage the lower surfaces of the grooves 12, 11 and rotate the member 3 until eventually the arm 7 lies vertically downwards against the wall of the channel, Fig. 1 (not shown). The grooves may be replaced by slots in the wall of the channel. In a modification, the wall of the channel has at least one longitudinal groove receiving an extension of the load support and each extension has a locking member pivoted thereto and co-operating with teeth in the base of the groove.

Filed: 1937-08-26
Abstract: 494,444. Feeding sheets. BACKHOUSE, H. T. Aug. 26, 1937, No. 23437. [Class 100 (i)] Sheets are fed from a pile P by a suction separator 3 acting on the rear edge of the pile and moving the edge of the sheet into contact with the underside of a feed roll or band 4 with which co-operates intermittently a roller 5 by means of which and a band 6 the sheet is carried to the upper side of the roll or band 4. The parts 3, 4, 5 operate at such relative speeds that the sheets are fed by the roll or band in the form of a continuous stream with the front edge of each sheet overlying the rear edge of the preceding sheet. The stream of sheets is carried by a conveyer band 7 to a conveyer 8 which is reciprocated laterally to register the sheets in succession against side lays 11. The conveyer 8 is arranged at a slightly lower level than the conveyer 7, so that the leading sheet is relieved of the weight of succeeding sheets as it drops on to the conveyer 8. Two or more lifting suckers 3 may be used and separation may be assisted by combing wheels, or by an air blast or both, and the lifting suckers may be given movements upwards and away from one another as described in Specification 427,041 to stretch the lifted sheet.

Title: Improved process for the oxidation of toluene and xylene
IPC: C07C51/265
Filed: 1962-06-19
Abstract: A process for the oxidation of the aliphatic side chains of toluene or xylene to the corresponding carboxylic acids with molecular oxygen or gases containing it, such as air, is carried out in the presence of a cobalt oxide catalyst insoluble in the hydrocarbon to be oxidized and remaining insoluble in the reaction mixture from the beginning to the end of the oxidation.  The cobalt oxide is prepared by a dry method and is preferably subjected prior to use for the first time to a treatment with boiling water for a duration of 10-180 minutes.  It contains an oxygen percentage higher than that corresponding to the formula CoO and preferably an oxygen content of 25-35%.  The catalyst is preferably utilized together with an inert finely divided substance.  In an example toluene is oxidized in an autoclave to benzoic acid by drawing air therethrough in the presence of cobalt oxide obtained by grinding cobalt carbonate to a fine powder and passing air at 600-700 DEG  C. therethrough for about 2 1/2 hours and thereafter placing the powder in water and boiling for 1 hour and filtering.  In another example, para-xylene is oxidized to a mixture of toluic and terephthalic acids.  In a further example, the oxidation of toluene to benzoic acid is described in conjunction with a suitable apparatus.ALSO:A cobalt oxide of a higher oxygen content than cobalt monoxide is prepared by treating metallic cobalt, cobalt oxide or hydroxide or a salt of divalent cobalt with a volatile acid, e.g. cobalt, carbonate or nitrate, with oxygen or a gas containing molecular oxygen at 200-800 DEG  C., the cobalt or cobalt compound being in the dry state and no liquid medium being present.  Reference is made to cobalt oxides having oxygen contents of 25-35% by weight.
