Abstract: 422,186. Converting. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. April 4, 1933, No. 10126. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 7, 1933]. [Class 38 (ii)] Relates to gaseous-electric discharge apparatus for converting D.C. into A.C. in which a condenser is used for effecting commutation and consists in connecting the condenser in circuit through auxiliary valves so that the moment of commutation may be varied and loads with lagging or leading power factors supplied. In a parallel type inverter, Fig. 2, in which discharge devices 4, 5 are supplied from a D.C. circuit 1, 2 through the primary winding 6 of a transformer 8, the commutation condenser 9 is connected between the valve anodes through pairs of reversely connected valves 11, 13 and 12, 14. By this means the condenser 9 periodically charges and the charge is retained until the moment at which it is desired to commutate. Commutation is effected by rendering the appropriate pair of auxiliary valves conductive. In the form shown in Fig. 3, the condenser 9 is connected to the anodes of the main valves through uncontrolled valves 15, 16 and to the cathodes of the main valves through grid controlled valves 17, 18. The condenser is charged from an auxiliary transformer 19. To commutate current from the valve 4 to the valve 5, valve 18 is made conductive so as to connect condenser across the main valve 4 through the auxiliary valve 15. Similarly, current is commutated from the valve 5 by rendering the valve 17 conductive.

Patent GB-679400-A (GB)
Title: Improvements in or relating to methods of preparing salts of polybasic acids
IPC: C07C51/265
Filed: 1950-05-02
Abstract: Acids of the formula <FORM:0679400/IV (b)/1> where R is C1-C4 alkyl, n and m are 1-3 and X is a carboxylic, sulphonic or oxyacetic acid group, are converted into aqueous solutions of their alkali metal salts and heated to 200-350 DEG  C. in the presence of an oxygen-containing gas.  One or more of the groups R is thus oxidized to carboxyl, the product being isolated as a salt.  The initial solutions are prepared by treating the acids with an alkali hydroxide or salt of an acid weaker than that being oxidized.  The reaction is assisted by the presence of a catalyst which may be (1) ferric oxide with or without an oxide of a Group II, III or IV metal; (2) an oxide or hydroxide of silver, lead or selenium; (3) a cobalt oxide, hydroxide or salt; or (4) a salt of an oxyacid of chromium, manganese or vanadium.  Suitable catalysts are listed.  An aldehyde and/or ascaridole may be added as promoter by virtue of free-radical liberation; the aldehyde is preferably that corresponding to the acid being oxidized.  The process may be carried out in batch, semi-continuous or continuous operation. Examples show the oxidation of salts of the toluic acids to phthalic, isophthalic and terephthalic acid salts, 3 : 5-dimethylbenzoic to 5-methylisophthalic and trimesic, m- and p-tolyloxyacetic to m- and p-carboxyphenoxyacetic, toluene-p-sulphonic to p-sulphobenzoic and p-xylene-sulphonic to sulphotoluic acid salts.  Catalysts used are ferric oxide alone and with aluminium, zinc and cerium oxides, potassium permanganate, lead chromate; potassium metavanadate, iron vanadate, cobalt acetate, cobalt hydroxide, cobaltous oxide with alumina, selenium dioxide, lead dioxide and silver hydroxide. Promoters used are ascaridole and p-tolualdehyde.  Other specified starting materials are cumic acid and p-ethylbenzoic acid.ALSO:Catalysts for the oxidation of salts of alkyl-substituted aromatic acids to the corresponding dibasic acid salts comprise mixtures of ferric oxide with oxides of metals of Groups II, III and IV of the periodic table.  Examples show the production of catalysts comprising equal moles of ferric oxide and (1) alumina; (2) zinc oxide; and (3) cerium oxide.  These are prepared by co-precipitating the metals as hydroxides and roasting the latter. Barium, magnesium and zirconium oxides are also specified for mixture with ferric oxide.

Title: Improvements in and relating to means for giving visible signals
IPC: B63B51/04
Filed: 1930-04-04
Abstract: 352,987. Discharging flares. SUTHERLAND, R., 3, Lombard Street, London. April 4, 1930, No. 10816. [Class 9 (ii).] A ship is provided with means for mechanically discharging signal flares at predetermined intervals of time, preferably under distant control, the flares being ignited on touching water. Flare canisters 5 are pressed into the ends of metal casings 3 integral with a frame 1 against the action of a spring 9 and rotated, the plugs 6 of the canisters being screwed on to the ends of rods 15, slidable in tubes 11 screwed into the plungers 7. Each tube 11 carries a slotted collar 13 which, when retracted, is pushed past the end of a pivot pin 21. The pin is so shaped that it has to be rotated about 5‹ by hand against the action of a spring 25 to allow the sleeve 13 to pass, after which the sleeve 13 is held. To release the flares periodically, a motor 51 which may be run by clockwork, normally wound, is released by energizing a solenoid 61 from some remote control point. The motor drives through gearing 55, 57 a shaft 41, cams 43 on which abut against arms 34 of bell-crank levers 33. When one of the weights 35 passes the dead-centre the corresponding lever 33 rocks its arm 36 to depress a head 27 mounted on a spindle 26 guided in a frame 1, the consequent rotation of the pin 21 releasing the sleeve 13 whereupon the plunger 7 ejects the canister 5, the plug 6 being retained on the rod 15. The timing of the release of each flare canister is obtained by spacing the cams 43 and adjusting the speed of the motor 51.

Abstract: 823,954. Vibratory mechanism. JUNKERATHER GEWERSCHAFT. April 10, 1956 [April 22, 1955], No. 10863/56. Class 80 (4). A cylinder 1, which may be connected to a feeding shoot for a mixing machine, is vibrated by a rotating eccentric mass comprising one or more tubes 7 containing fluid, e.g. mercury, or granular material, the amount of which may be varied during rotation to vary the amplitude of vibration. The one tube 7 shown is carried between coaxial rotatable members, one of which is shown at 5, the two members being interconnected by a second tube 6 and being driven by a pulley. When it is desired to increase the amplitude of vibration a mercury storage tank 8, rotatably mounted on the cylinder 1, is angularly raised from the position shown, whereupon mercury flows through a radial duct 9 and an axial bore in a non rotatable bolt 10 to a space 11 in the member 5, whence it is moved centrifugally into the tube 7. Air displaced from the tube 7 escapes to the tank 8 through a channel in the bolt 10. The tank 8 has a window and a scale to indicate the amount of mercury remaining in the tank and thus enable the required amplitude of vibration to be set. To reduce the amplitude, a bore 5a in the member 5, which is normally closed by a rubber cup on a spring-pressed lever 15, is opened by turning a lever 16 on a bolt 17 engaging the lever 15 through a ball-bearing bush, whereupon mercury escapes centrifugally to a space 20 communicating with the tank 8. It is stated that the vibratory mechanism may be employed for the compression of granular materials, the mixing of chemical elements or the withdrawal of granular materials from bunkers. Specification 738,960 is referred to.

Title: Improvements in sectioning machines
Inventor: FAVOT JEAN
IPC: B24B27/06
Filed: 1969-03-03
Abstract: 1,253,583. Sawing. J. FAVOT, and R. WILLAUME. 3 March, 1969 [12 March, 1968], No. 11103/69. Heading B5L. [Also in Division B3]  A sectioning machine comprises a fixed frame and work support 49, a circular cutting tool, such as a grinding wheel or circular saw 2, a mechanical member 6 for moving the tool, and an hydraulic control unit 8 having a first piston and cylinder unit 18 for controlling the cut of the tool, a second piston-and-cylinder unit 16 for regulating the depth of cut of the tool, and a third piston-and-cylinder unit 15 for controlling the approach of the tool. As described, the tool is a grinding wheel 2 carried at the end of an arm 3 mounting a motor 4 for driving the wheel. The arm is pivotably mounted on one end of a second arm 6 which is mounted on a pivot 7 on the frame of the machine and has its other end connected to a pin 9 of the unit 8 which is mounted to rock about a pivot 10 on the frame. The pin 9 is secured to the sleeve 18a of the unit 18, the piston 18b of which is integral with the pistons 15a, 16b of the units 15, 16. The sleeve 18 is slidable in a housing 11 of the control unit 8 and can abut and drive the sleeve 16a of unit 16. Sleeve 15a of unit 15 is fixed in the housing. The control unit 8 is controlled by an hydraulic and electrical circuit so as to energize the unit 15 to effect the approach of the grinding wheel towards the workpiece. At a predetermined position which may be determined by the grinding wheel interrupting a light beam or jet of liquid, the approach movement is stopped. The interruption of the beam of jet has the effect of compensating for wear or truing of the wheel. As the wheel is reduced in size, the approach stroke of the unit 15 increases and such increase is used by way of a cam 77 and switch 78 to increase the speed of rotation of the wheel. At the completion of the approach stroke, the unit 16 is operated to regulate the depth of cut and unit 18 is actuated to effect the cutting: The arm 3 is connected by a rod 53 to a double acting device 51 activated by limit switches 56, 57 to effect oscillation of the arm during cutting, the switches being activated by arms 62, 63 operated by the arm 3. The switch 56 is carried by a bracket 58 associated with one 66 of the jaws for clamping the workpiece 50, which jaw is adjustable by a screw 66a. The other switch 57 is carried by a bracket 59 on the other jaw 67 which is operable by a piston- and-cylinder device 68 to clamp the workpiece. The machine is only operable when the clamp is gripping the work and a limit switch which is activated by the end of the workpiece to determine the length of the workpiece to be cut off is operated. In another embodiment, the oscillating movement is replaced by a reciprocating movement.
