Title: An improved method for cleaning wool and apparatus therefor
IPC: D01B3/08
Filed: 1937-04-08
Abstract: That portion of an alkaline detergent scouring solution in a wool cleaning plant which contains substantially the whole of the dirt is rapidly withdrawn from the bath at a low point in the scouring stage, either continuously or intermittently, and is transferred to one or more settling tanks where the contents are heated to a temperature above the hot scouring solution and where solids and grease are separated from the solution, the purified liquid being returned to the scouring solution.  Solids and grease are preferably separately removed from the settling tank or tanks, and a final separation of the grease may be effected by a centrifuge.  Loss of volume of the scouring solution is made up by the addition of water to the solution in the settling tank.  Used scouring liquor of low dirt content and high grease content collected from squeeze rolls associated with the scouring bowls may be separately transferred to the settling tank or tanks.  The concentration of detergent in the scouring solution is maintained by additions in accordance with electric conducting determinations of the scouring solution, as described in Specification 470,000.

Title: Improvements in or relating to endless track vehicles
IPC: B62D11/10
Filed: 1926-04-16
Abstract: 262,377. Renault, L. Dec. 3, 1925, [Convention date]. Independent driving on opposite sides.-Endless track vehicles in which steering is effected by a differential driving gear such as is described in Specification 112,266 is provided with an auxiliary transmission operating when the main transmission is de-clutched to turn the endless track wheels in opposite directions. As described in Specification 112,266 the drive from the engine 1 is transmitted through a main clutch 2, changespeed gear 4, shaft 5 and differential gear 7 to the half shafts 9, 10 carrying the driving sprockets. The auxiliary transmission comprises belt or.other driving gear 13 in front of the main clutch 2 and driving an auxiliary shaft 15 which is connected through a planetary or other reversing gear A to a shaft 16. The shaft 16 carries a pinion 27 gearing with pinions 19, 20 on two shafts 21, 22, which thus rotate in opposite directions. The shaft 21 is adapted to drive the half-shaft 9 through gearing 23 and the shaft 22, which is provided with a clutch B, is adapted to drive the half-shaft 10 through gearing 24. For normal running the clutch B is de-clutched and the drive is transmitted through the differential gear 7. To slew the vehicle about its centre, the main clutch 2 is de-clutched'and the clutch B is engaged. The auxiliary drive now rotates the halfshafts in opposite directions and so slews the vehicle. In a modification the differential gear is provided with an auxiliary brake drum the auxiliary drive being geared to a bevel wheel on the brake drum sleeve surrounding 'one of the half-shafts.

Title: Improvements in control circuits for cathode-ray apparatus
IPC: H03J7/32
Filed: 1941-09-08
Abstract: 582,125. Wireless receiving systems. DODDS, J. M., SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 8, 1941, No. 10137. [Class 40 (v)] A circuit arrangement is designed to supply scanning voltage to a thermionic reactance so as to sweep through a range of tuning frequencies, and simultaneously to supply current to the deflecting coils of a cathode-ray indicator to indicate visually which frequencies are active. Direct couplings are used in the circuit so that a slow manual tuning control may be substituted for the recurrent sweep. The circuit is primarily intended for use with panoramic receivers. A source 1 of saw-tooth or other voltage is coupled by a potentiometer 4 to the grid of a valve 6 which thus upplies current to the deflecting coil 11 in series with a resistance 12. A second valve 7, energized in phase opposition to the valve 6 by virtue of a common cathode resistance 8, has a second coil 14 and a resistance 15 in its anode lead. Bias for both grids is afforded in part by a divider 20, 21 connected across the H.T. supply 17 for the valves 6, 7 and the generator 1. A resistance 25 connected between the junctions of 11, 12 and 14, 15 is adjustably tapped to the grid of a thermionic reactance 22 which controls the tuning of the radio receiver. The reactance valve 22 and the associated local oscillator &c. are supplied from a source 26 which has its negative terminal joined to the positive terminal of the source 17. The tuning of the receiver is recurrently varied by the valve 22 in phase with the deflection of the cathode-ray by the coils 11, 14. For manual control of the tuning, the generator 1 is cut out by a switch 27, and a manually-controlled potentiometer 30, 31 is put into the grid circuit of the valve 6 by a switch 28. Specifications 582,129 and 582,130 are referred to.

Title: Estimation of electrolytic corrosion
IPC: G01R31/02
Filed: 1974-03-07
Abstract: 1466782 Measuring electrolytic corrosion: Measuring current integral SANYO ELECTRIC CO Ltd 7 March 1974 [12 March 1973 17 April 1973 20 July 1973] 10278/74 Headings G1N and G1U In order to estimate the rate of electrolytic corrosion of a metal object, such as a railway line RL, Fig. 5, in contact with the earth, the object is connected to an earth electrode EE buried in the ground via an apparatus CMA which integrates, with respect to time, the absolute value of the resulting current, this being effected by integrating separately the positive and negative portions of the current in two integrators. As described current is integrated by a device referred to as a "solid state electro-chemical potential memory", comprising a solid electrolyte (31), Fig. 3, (not shown), sandwiched between electrodes (32, 33), and a voltage sensing electrode (34). In use, if a current of, for example (30) microamps is caused to pass, conventionally, from electrode (33) to electrode (32), the potential across the device, measured between the electrode 7 and the sensing electrode 6 to avoid including the voltage dropped across the device by the actual current flowing, rises linearly with time as shown in Fig. 2. Two of these devices MD1, MD2 Fig. 4, are utilized in the preferred embodiment of the unit shown at CMA, Fig. 5, so arranged with diodes D11, D12, D21, D22, Fig. 4, that positive current from terminal TC to the earth terminal TE flows via integrator MD2, and negative current via integrator MD1. As shown in Fig. 4,the sensing electrodes of the two integrators are connected to amplifiers AP1 and AP2 which drive meters Ml and M2, and the system is powered by a stabilized supply CV1, CV2. Various switches are included in the circuit permitting the open current battery voltage to be displayed on meter M1 and allowing the integrators to be reset to zero, by passing current in the reverse direction through them, before the system is put into operation. In a modification Figs. 7 and 8 (not shown) to avoid errors arising from volts dropped across the routing diodes D11, D12, D21, D22, the polarity of the voltage appearing at terminal TC can be sensed and used to control relays which switch the required integrator into circuit.
