Title: Improvements in or relating to processes for the production of derivatives of diels-ader adducts of hexachlorocyclopentadiene and cyclopentadiene
IPC: C07C23/20
Filed: 1948-03-05
Abstract: A monochloro derivative of the Diels-Alder adduct of hexachlorocyclopentadiene and cyclopentadiene, believed to be 1 : 4 : 5 : 6 : 7 : 8 : 8-heptachloro - 4 : 7 - methano - 3a : 4 : 7 : 7a - tetrahydroindene ("Ring Index" nomenclature), is manufactured by brominating said adduct in the presence of a peroxide, hydrolysing the resulting monobromo derivative to the monohydroxy derivative, and treating this with a compound capable of replacing the hydroxy group by chlorine.  The bromination is advantageously effected by adding liquid bromine, preferably in an inert solvent (e.g. carbon tetrachloride or chloroform) to a solution in a similar solvent of the adduct and 0.001-0.01 mol. per cent thereof of an organic peroxide (e.g. benzoyl or lauryl peroxide or ascaridol).  The hydrolysis of the monobromo compound may be effected directly by means of an aqueous alkaline reagent (e.g. sodium or potassium hydroxide, carbonate or bicarbonate), or indirectly by treatment with the salt of an organic acid (e.g. sodium, potassium or silver acetate, propionate or benzoate) in an organic solvent (e.g. ethylene glycol, carbitol or preferably glacial acetic acid) and subjecting the resulting ester to alcoholysis, e.g. by treatment with an alcohol (preferably one of low molecular weight such as methanol, ethanol or ethylene glycol) in the presence of an ester-interchange catalyst (e.g. sulphuric or hydrochloric acid, or sodium methoxide or acetate).  The replacement of the hydroxy group by chlorine may be effected by refluxing the hydroxy compound with thionyl chloride in benzene, or by treating it in an inert solvent dry hydrogen chloride or a mixture of concentrated hydrochloric acid and zinc chloride. Examples illustrate certain of the foregoing procedures. Specification 618,432 is referred to.ALSO:Insecticidal compositions contain as active ingredient a monochloro derivative of the Diels-Alder adduct of hexachlorocyclopentadiene and cyclopentadiene, believed to be 1 : 4 : 5 : 6 : 7 : 8-heptachloro-4 : 7-methano - 3a : 4 : 7 : 7a - tetrahydroindene ("Ring Index" nomenclature).  This compound may be used in the form of mineral oil sprays, dust, aqueous emulsions or aerosols, alone or in association with other toxicants.

Title: Apparatus for the electrical separation of mixed particles
IPC: B03C7/06
Filed: 1935-03-05
Abstract: 441,965. Electrostatic separators. METALLGES. AKT.-GES., 45, Bockenheimer Anlage, Frankfort-on-Main, Germany. March 5, 1935, No. 6933. Convention date, March 9, 1934. [Class 72] In an electrostatic separator of the kind in which an electrostatic field is located between the guide surface for the material to be treated and an electrically charged rotating roller and an intermediate electric field is also produced which the material traverses before it reaches the main field, an earthed intermediate potential roller formed of semi - conductive or non-conductive material and rotating in the same direction as the feed roller is located between an earthed feed roller and an insulated high potential roller rotating in the opposite direction to the feed roller. The feed roller and/or the guide surface are provided with a vibratory or jigging device and the guide surface may be provided with dividing ribs arranged in the direction of flow of the material. The material is fed by a channelled rod 2 from a hopper 1 on to the jigged guide plate 3 and thence by the feed roller 5 into the main field produced by the high potential roller 6 and the intermediate roller 8. The material adhering to the rollers 6, 8 is removed by scrapers 14, 9 and passes by an inclined surface 11 into a receptacle 13. The material not affected by this field passes by an inclined surface 10 into a receptacle similar to receptacle 12 or if the treatment takes place in more than one stage passes from the surface 10 on to a guide surface 3a and is subjected to further treatment in the field produced by the rollers 6a, 9a, the separated material being collected in the receptacle 13a and the unaffected material in other receptacle 12. The preliminary separation of the material is effected by a second earthed intermediate potential member 7 located above the guide surface 3 and if the treatment is carried out in two stages, another intermediate potential member 7a may be located above the guide surface 3a. When the treatment is carried out in more than one stage the operating voltages used may be graduated.

Title: Improvements in or relating to on-load electric transformer tap changing systems
IPC: H01F29/04
Filed: 1951-03-22
Abstract: 732,654. Transformers. JANSEN, B. March 22, 1951, No. 6934/51. Class 38 (2). An on load transformer tap changing system comprises a step selector having a series of contacts connected to each transformer tapping, a load change-over switch having a plurality of switch blades co-operating with main and auxiliary contacts and operable simultaneously with the step selector, and at least one inductive current divider having a number of cores corresponding to the number of blades, of the load change-over switch, each core being supplied with a pair of magnetically opposed windings, the connections between the step selector, the load change-over switch and the windings on the inductive current dividers being such that the load current divides equally between the plurality of switch blades thus reducing the wear on each blade. As the step selector Wal... Wa3; Wbl ... Wb3 is moved to change from tap B to tap A on the transformer winding the load change-over switch blades L1 ... L3 move from contacts Hb1 ... Hb3 to contacts Ha1 ... Ha3. If during the movement of the blades L1 ... L3 one blade leaves its associated contact before the other blades (in the Fig. 1 the dotted lines indicate blade L1 leaving contact Hb1 before the blades L2, L3 leave contacts Hb2, hb3) the current path b10 from the step selector would tend to be interrupted, thus the windings b32, 11 on the current divider Stb would tend to be de-energized, thereby upsetting the normal magnetic balance which exists in the cores when the current is equally divided. Thus a voltage drop will exist in windings b31, b12 and thus voltages will be induced in windings b32, b11 which will produce a potential difference across the break between switch blade L1 and contact Hb1 sufficient to cause an arc to be struck across the break, thus to restore the current flow and the equality of current division. The cores of the current dividers may be separate as shown to the left of the Figure or have common yokes as shown on the right. The load change-over switch may be provided with additional contacts so connected that current only flows in the current dividers during the switching periods, or if the divider is connected between the load change-over switch and the current take-off AL only one divider is necessary. The normal auxiliary resistors and auxiliary contacts ha1 ... ha3 ; hb1 ... hb3 are provided as is normal in the tap changing art.

Title: Improvements to control systems for infinitely variable drive ratio transmissions
IPC: F16H61/662
Filed: 1958-03-04
Abstract: 867,881. Variable-speed control. ANCIENS ETABLISSEMENTS PANHARD ET LEVASSOR S.A., DES. March 4, 1958 [March 8, 1957], No. 6968/58. Class 80 (2). A steplessly variable control for a disc-androller gear 42 on a motor vehicle comprises a piston 8 actuating a valve 18 which supplies pressure liquid from a source 23 to a gear-shift motor 25 and is subject to opposing control pressures provided respectively by liquid at a pressure proportional to the square of the engine speed supplied to a chamber 33 by an enginedriven pump 28, and springs 12, 13 variably compressed through an arm 6 and piston 17 by the engine throttle pedal 1. When the downward pressure of the throttle pedal 1 predominates, the piston 8 is moved down, closing the valve 18 and opening a port 19 which exhausts at 21 a chamber 24 of the gear-shift motor 25. When upward speed-responsive pressure 9 predominates, the piston 8 is raised, closing the exhaust port 19 and supplying pressure 22 from the source 23 through a line 20 to the chamber 24 of the gear-shift motor 25. Control pressure in the chamber 24 is permanently opposed by liquid at full pressure of the source 23 acting in an opposing chamber 26 and effective on a smaller area of the shift piston 25 whereby when the chamber 24 exhausts, pressure in the chamber 26 moves the shift piston 25 leftward and with it the friction roller 43 towards increasing reduction ratios, and when the chamber 24 is pressurized the opposite movement occurs. The central zero position of the friction roller 43 provides engine idle with automatic drive take-up on increasing engine speed, and is adjusted by varying the initial compression of the springs 12, 13 by a screwstop 29. The load on the throttle pedal 1 due to the springs 12, 13 may be reduced by liquid pressure 32 supplied above the piston 17 from the control passage 9. Specification 833,841 is referred to.

Title: Improvements in tension control means for running webs
IPC: B65H23/06
Filed: 1947-03-13
Abstract: 630,995. Fluid-pressure servo motor-control systems ; valves. TRIGGS, W. W. (Cameron Machine Co.). March 13, 1947, No. 7060. [Class 135] A machine in which the tension of a running web of flexible material, e.g. paper, is controlled by a variable speed-control device whose effectiveness is varied by movement of a reciprocatory carriage having a roll that engages a bight in the web, comprises a fluid-actuated operating-device controlling the speed control device, valve mechanism in a duct connecting the operating device with a source of pressure fluid, and two controllers for said valve mechanism, one of said controllers acting in response to movements of said carriage, and the other controller being responsive to the fluid pressure in said operating device. As shown in Fig. 1, the tensioned web passes from a roll MR over guide rollers 10, 11, between which is a tensioning roller 12 carried by a carriage 13 slidable in a slot 130, and thence through processing, e.g. printing, rolls C and over guide rollers 101, 11<SP>1</SP> and a roller 12<SP>1</SP> carried by a slidable carriage 13<SP>1</SP> to a winding drum 23. The carriages 13, 13<SP>1</SP> are connected by links 20, 20<SP>1</SP> to bell-cranks 18, 18<SP>1</SP> loaded by weights 15, 151 attached to cords 16, 16<SP>1</SP> passing over sheaves. Above each carriage, and mounted for engagement therewith is a cam lever 48 or 48<SP>1</SP> the upper edge of which engages a stem 44 or 44<SP>1</SP> of a control valve 32 or 32<SP>1</SP>. The valve 32 controls a single-acting diaphragm power device 25 which, through a lever, acts on a rod controlling a variable brake for the roll MR, whilst the valve 32<SP>1</SP> controls a similar power device 25<SP>1</SP> for adjusting a slipping clutch 24 in the drive to the drum 23. Each of the valves 32, 32<SP>1</SP> consists of an inlet valve member 35, Fig. 5, coacting with a fixed seat 36, and an exhaust valve member 38 coacting with a seat 39 formed in a member movable with a diaphragm 43 exposed to the pressure in a chamber 34 connected with the power device. Movement of the diaphragm is opposed by a spring 47 whose compression is varied by movement of the plunger 44 whereby a change in tension of the web causing movement of the carriage 13 or 13<SP>1</SP> alters the compression of the spring 47 and varies the pressure applied to. the power device, and thereby the braking effect applied to the roll MR or the clutch pressure in the drive to the drum 23. A byepass leak 50 causes the exhaust valve member to remain slightly open, thereby preventing sticking of the latter. In a modification, the leak 50 is adjustable by a needle valve, and in a further modification, a leak, also controlled by a needle valve, connects the chamber 34 with the atmosphere. Specification 631,023 is referred to.

Filed: 1973-02-14
Abstract: 1399073 Toys IDEAL TOY CORP 14 Feb 1973 [30 March 1972] 7177/73 Heading A6S [Also in Division F2] Prevention of overwinding of the spring motor in a toy motor car, &c 12 when using a winding mechanism 10 upon which the car &c is placed so that winding can be effected on pulling a pivoted handle 54, is achieved by an overload tension spring 58 connected between the handle and a gear segment 50 transmitting drive through a gear train 36 to a winding clutch hub 20 .engageable by the toy car, &c. The gear segment 50 is journalled by a pin 52 in the winding mechanism housing 22, and is connected at one side by a pivot 56 with the handle 54. The spring 58 connects the other side of the gear segment 50 to the handle 54. The gear segment 50 meshes the small gear 42 of a gear pair 40, 42 integral with a shaft slidable along a slot 46 so that the larger gear 40 can be engaged and disengaged from a pinion 30 fast with the winding clutch hub 20. Ratchet teeth 34 on the clutch hub can be engaged by coacting, oppositely-directed ratchet teeth 36 on a driven winding hub 18 in the toy car, &c 12. Wheel holders 26 in the winding mechanism housing 22 receive the wheels 14 of the toy car 12, &c. A stop 74 on the handle 54 can be engaged with a stop 76 in the housing 22 to limit pivoting of the handle when winding of the spring motor has been completed and the spring 58 between the handle and gear segment 50 has been stretched by continued pulling of the handle. In use, the winding mechanism 10 is placed on the floor, &c, and the toy car, &c 12 is positioned to engage its winding hub 18 with the mechanism winding hub 20, as shown. Movement of the handle 54 anticlockwise, Fig 2, slides the gear pair 40, 42 along the slot 46 to disengage the gears 40, 30. Pulling the handle 54 clockwise slides the gear pair 40, 42 back along the slot.46 to reengage the gears 40, 30 and wind the spring motor. If the spring motor has been fully wound, rotation of the winding hub 20 is resisted, and continued pulling of the handle 54 stretches the spring 58, the handle turning about the pivot 56 relative to the gear segment 50. Reference is made to Specifications 1373874 and 1373876.
