Title: Improvements in electrode systems for electrolytic condensers and rectifiers
IPC: H01G9/02
Filed: 1932-06-07
Abstract: 384,203. Electrolytic condensers and rectifiers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. June 7, 1932, No. 16074. Convention date, June 26, 1931. [Class 37.] One electrode consists at least partly of one of the metals of the first sub-group of the fourth principal group of the periodic system, whereas the other electrode together with a supply conductor is constituted bv an electrolytically conducting substance consisting of an anhydrous solution of an electrolyte, in particular in an alcohol. In the construction shown, a copper vessel 1 encloses an electrode 2 consisting of a zirconium band which is rolled up and has its successive turns separated by celluloid bands 3. The vessel 1 is filled with a solution 4 consisting of glycerine and primary potassium phosphate (KH2P04) in the proportion of 50 grams of the phosphate to the litre of glycerine. The electrode 2 and bands 3 rest on an apertured base 5 of ebonite &c. Such a condenser is suitable for smoothing direct current, and is stated to pass about 0.02 milliampere per microfarad in the blocking direction at 500 volts. The solution 4 may alternatively consist of glycerine and anhydrous phosphoric acid, or of glycerine, alum, and citric acid. In the latter case the solution must be boiled for some time to remove the water of crystallization of the alum. A condenser for use with alternating current has two electrodes of zirconium, titanium, hafnium, or thorium. The electrodes may be oxidized before placing in the electrolyte in which they are to be used. Suitable solutions for such oxidation are phosphoric acid in glycerine at 150‹ C., or caustic alkali in ethyl alcohol at 78‹ C.

Abstract: 1493991 Valves SUNDSTRAND CORP 18 April 1975 [22 April 1974] 16127/75 Heading F2V In a pressure regulating valve for a directional control valve a plunger 32 is moved against a spring-loading 37 by the pressure differential in chambers 46, 47, which are connected respectively to the operative work port of the directional control valve and an inlet 40 via passages 54, 52 and 56. The plunger moves to control flow from the inlet 40 to a by-pass passage 42 and a passage 39 connected to the inlet of the directional control valve. A signal passage 23<SP>1</SP>, which connects with the operative work port of the directional control valve, a passage 45, a ball check valve 73 and passages 65, 68 connect with the chamber 46 to allow unrestricted flow thereinto. A check valve 63 has a notch (82) in its end bearing against its seat 69 to allow restricted flow from chamber 46 to exhaust port 43 and to damp pressure fluctuations during normal regulating movements of the plunger, the check valve being movable off its seat by higher pressures in chamber 46 to allow unrestricted flow to exhaust port 43. A pressure relief valve 85 is operative to exhaust chamber 46 at still higher pressures. The restricted flow to the port 43 from chamber 46 may be through a "leaky" end of plunger 32 or a restriction therethrough. An adjustable stop 50 limits the maximum flow from the inlet 40 to the port 39.

Title: Improvements in and relating to tractor-hauled mowing machines
IPC: A01D34/07
Filed: 1945-06-27
Abstract: 594,498.  Agricultural mowing- machines. CUNDEY, J. E., CUNDEY, W. B., and CUNDEY, E. G. June 27, 1945, No. 16339. [Class 6 (iii)] A tractor hauled mower has a hinge bar swivellably connected to the rear of the tractor, the hinge bar near the cutter end having fixed to it an upwardly extending block freely movable in guides carried by a swivelling frame of the mower so that the draught of the cutterbar is transmitted to the hinge bar by means of said guides, the hinge bar when moved by ground variations being still controlled by the guides. In the construction shown, a bracket 10 and a fixed box-section 15 of the tractor has the swivelling frame of the mowing machine detachably coupled thereto, said swivelling frame consisting of box-section girders 30, 31 connected together by further similar girders 32, said frame carrying a hinge bar 33. A spring-loaded bracket 35 pivoted on the boxsection 15 adapted to engage with a socket at one end of the girder 31 holds the frame in the working position, Fig. 5 shows the inoperative position, said bracket having a flanged boss 41 mounted at the top through which a rod 42, separately pivoted on the box-section 15, passes. A spring 45 is fitted around the rod 42 which can be compressed by a handle 46, thereby resisting the pivotal movement of the bracket 35. A roller 47 on the bracket 35 enters the socket when the frame is in the working position by means of a striker 50 engaging with a ramp 51 on the box-section 15. Thus much force will be necessary to withdraw the socket by deflecting the bracket 35 against the spring action. A pair of vertical guides 57 on a bracket 56 contains a movable block 58 on the hinge bar 33, the hinge bar being thus controlled by said vertical guides. The knife of a cutter bar 59 is driven by a pulley on the frame which is itself driven by a pulley on the box-section 15.

Filed: 1967-04-10
Abstract: 1,190,843. Supply systems for discharge lamps. W. F. SINN, and R. SHIVELY. 10 April, 1967, No. 16349/67. Heading H2H. [Also in Division G2] A xenon discharge lamp 34 which provides illumination for a slide projector is controlled to emit an increased level of illumination for a predetermined period to provide a high intensity flash for photographic purposes. To this end, the A.C. chokes 41 and the D.C. choke 69 in the supply to the lamp are provided with normally-open short circuiting contactors RL7, PA1316 whose condition is controlled by a thyratron GT1 which is normally non-conductive due to the choice of a resistor R4 in its firing circuit. Thyratron GT1 is fired by connecting a resistor R2 in parallel with R4 through the action of a camera shutter (terminals P6) or a photo-cell (terminals P5) or by manually closing a switch SW6 to test the operation of the circuit itself, which may be disabled by opening a switch SW5. Firing of the thyratron GT1 actuates a control circuit including relays RL1 ... RL5, RL7, of which the relay RL3 includes a time delay (through a capacitor C6) producing closure of members RL7 and PA1316 to short-circuit chokes 41, 69 for a predetermined time corresponding to the predetermined flash period of the lamp 34. For normal operation of the lamp 34, starting is provided automatically or manually by appropriate actuation of switches SW3, SW4, using a conventional ignition pulser 33 of the capacitor charge and discharge type. Members SW4, RL6, C7 provide a timing arrangement to allow only a predetermined number of starting pulses when operating in the automatic ignition mode. The flashing control arrangement is such that the signal applied to terminal P5 or P6 must be removed and reapplied at not less than a predetermined time later, to produce another operation of the arrangement. Various thermal and magnetic overload cut-outs are provided and the operation of the projector under normal and flashing conditions is described.

Title: New types of inhibitors and retarders for free radical reactions
Inventor: BARNARD DOUGLAS
IPC: C09K15/12
Filed: 1957-05-24
Abstract: The autoxidation and polymerization of natural rubber is inhibited or retarded by the addition of a small proportion of an organic thiolsulphinate or sulphoxide.  In an example, phenyl benzenethiolsulphinate is used in concentrations of 0,26 to 3,35% by weight to retard the cross-linking of rubber when exposed in vacuo to radiation from a Cobalt-60 source.ALSO:The autoxidation or polymerisation of unsaturated hydrocarbons, esters and organic sulphur compounds is inhibited or retarded by the addition of a small proportion of an organic thiolsulphinate or sulphoxide.  In the case of the autoxidation of unsaturated hydrocarbons and sulphur compounds, the inhibitor may, if desired, be formed in situ from the parent disulphide or monosulphide.  The retardation of the autoxidation of squalene, digeranyl, 1-phenyl-but-2-ene, n-butyl cinnamyl sulphide and ethyl linoleate is exemplified. Representative autoxidationretarders are: 1-methylallyl n-butyl sulphoxide, cyclohexenyl t-butyl sulphoxide, ethyl ethanethiolsulphinate, phenyl benzenethiolsulphinate, di-t-butyl sulphide, 1,3-dimethylallyl phenyl sulphide, dimethyl-disulphide, dicyclohexenyl disulphide, and diphenyl disulphide.  The retardation of the polymerisation of methyl methacrylate and of styrene by means of phenyl benzenethiolsulphinate, ethyl ethanethiolsulphinate, and p-methoxyphenyl - p - methoxy - benzenethiolsulphinate, are also given as examples of the invention.

Filed: 1942-11-24
Abstract: 578,406. Radiolocation. ROST, H. F., THUNELL, K. H., VIGREN, S. D., and CLAESSON, P. H. E. Nov. 24, 1942, No. 16625. [Class 40 (v)] [Also in Groups XXXV and XXXVI] Oscillation frequency.- The basic frequency or the degree of modulation of a frequency modulated transmitter of ultra-short waves is manually or automatically controlled by passing a portion of the radiation from a transmitter 101, for example, through a wave guide comprising two channels 95, 96 of different lengths so that they produce normally a beat frequency to which a cavity resonator into which they feed is tuned. One output passes through a detector 98 and amplifier 99 to a filtering and rectifying device 100 to produce a voltage on a grid leak 115, or measuring instrument,' which is the difference between the voltage developed in the filter circuits, these being respectively tuned to frequencies as slightly above and below the desired beat frequency. As shown, a correction of the degree of modulation of the transmitter 101 is obtained bv an electron tube 116, whereby an anode voltage of variable value is applied to a relaxation oscillator generator 127, but any suitable kind of regulator may be employed. To obtain small dimensions for the channels 95, 96, harmonics of the transmitted radiation may be used. The invention is described as applied in apparatus for measuring distances to an object by.measurement of the beat frequency between direct reception from the transmitter and reception of radiation reflected from the object, the apparatus comprising means for automatically scanning the sky by transmitted waves until reflected reception causes automatic following of the object. Alignment.-The transmitter 101 and a receiver 103 are mounted on a horizontal shaft 110 which may be turned by an A.C. reversible motor 15 having split fields controlled by valves 33, 34, the grid voltages of which are phase shifted for selective operation. The shaft 110 is carried by a vertical shaft 111 which is similarly operated by a motor 14. These motors may be manually controlled by a switch 89 to determine a given direction of radiation, after which intermittent and alternate action of the motors produces automatic and progressive scanning of a definite field, until the receiver 103 is energized by reflected waves to a degree sufficient to energize a relay R1, whereupon the motors are automatically controlled to cause the radiation to follow the reflecting object. To achieve this, a shaft 108 is constantly driven to rotate an aperture 106 in front of the receiver and to operate commutators 21 ... 24 so that filter networks such as 46, associated with the separate motor control circuits by operation of a relay R2 at the same time as R1, in turn receive radiation from opposite sides of two planes normal to each other and parallel with the receiver axis. If the energy received on appropriate sides of these planes is not equal, the motors operate to restore equality and the object is accordingly followed. Specification 578,420, [Group XXXVI], is referred to.
