Title: Improvements relating to the indicating mechanism of measuring instruments
IPC: G01D5/04
Filed: 1927-11-22
Abstract: 295,160. Paulin, J. G. Nov. 22, 1927. Barometers.-The movements of the vacuum box of a barometer are transferred to a swingable indicating member by means of a yieldingly suspended lever having arms of different length characterized by the fact that both arms of said lever are connected bv means of flexible bands or tapes with the vacuum box and the indicating member, the latter itself being yieldingly suspended. The vacuum box 1 is mounted on a support 3 and carries a yoke 4 upon which acts a coiled spring 5 the upper end of which is attached to a nut 7 prevented from rotation by a fork 6 engaging the frame. The spring may be tensioned by a screw 9 entering the nut and turned by a milled head 11. A lever 15 is suspended by a metal tape 16 from a support 17 and is connected at one end by a tape 14 to the capsule. The other end of the lever 15 is connected by a tape 18 to a short lever arm 21 on a spindle 19 carrying a pointer 20. Another short arm 26 is connected by a tape 27 to a fixture 28. The spindle 19 is connected at the ends by tensioned springs 22. 23 to fixtures 24, 25 the springs being under slight tension tending to turn the pointer to the right, Fig. 1. In use, upon a variation of atmospheric pressure the needle 20 is restored to zero by varying the tension of the spring 5 by turning the head 11 a disc 12 reading against a fixed pointer 13. In a modification, Fig. 3, the lever 15 is dispensed with and a spindle 30 mounted on end springs similar to the spindle 19 above carries two short arms which are connected by tapes 14, 34 to the capsule and to a fixture at the top respectively, and two longer arms connected by tapes 18 to arms on the spring suspended spindle 19 of the pointer 20. In a further modification the upper vertical arm of Fig. 3 is connected by a horizontal tape to a fixture and this tape is connected between the ends by a vertical tape to one arm on the spindle 19 another arm being anchored to a fixture by a tape.

Class 81 (i) A fumigating device adapted to discharge by combustion the vapour of a pest-controlling substance, comprises a container incorporating a solid self-combustible composition in which are embedded one or more enclosures which contain a liquid vaporizable pest-controlling substance absorbed on an inert absorbent, said enclosures isolating the pest-controlling substance from contact with the self-combustible composition and being wholly or partially destructible by the heat of combustion of the composition to release the pest-controlling substance. The self-combustible composition may include an additional pest-controlling substance and a vaporizable ingredient to reduce the risk of bursting the container. The container may contain a baffle separating the combustion chamber from a space into which the gases pass before emerging from the device. The self-combustible material comprises a combustible material, e.g. a carbohydrate such as sucrose and lactose, an oxygen yielding substance such as potassium chlorate, potassium perchlorate and potassium nitrate and a vaporizable substance such as naphthalene, azobenzene and D.D.T. Specified liquid pesticides are tetraethylpyrophosphate, hexaethyltetraphosphate, diethyl p-nitrophenyl monothiophosphate, mixtures of diethyl- and dimethyl-p-nitrophenyl monothiophosphate, p-butoxy p<SP>1</SP>-thiocyanodiethyl ether, Chlordane and nicotine.

Title: Improvements in controllers for reversible electric motors
IPC: H02P7/00
Filed: 1946-12-24
Abstract: 606,279. Controllers; control of motors. DICKINSON, S. Dec. 24, 1946, No. 31897/45. [Class 38(iii)] Continuous reversals; travelling between predetermined limits.-In order to obtain repeated reversals of an electric motor with a time delay between each reversal, a controller is provided comprising a motor-driven screw shaft 5 bearing a nut 13 upon which is resiliently mounted a rod 42 adapted to actuate switches 45 and 46 for stopping the motor when the nut approaches the limits of its travel in either direction. A switch 28 is adapted to re-start the motor and move the nut 13 to the left a predetermined period after the motor has been stopped by the switch 46, and a switch 57 similarly effects restarting of the motor in the reverse direction after stoppage by the switch 45. When the nut 13 moves to the end of its travel, towards the right for example, a cam 37 engages a head 38 of a catch 30 and raises it clear of a bar 34. Substantially at the same time the rod 42 actuates the switch 46. The release of the catch 30 causes a spring 35 to drive a piston 21 towards the right at a rate controlled by the setting of the screw 24, and, after an interval, a rod 26 engages the switch 28. With the nut 13 moving to the left, an arm 39 engages the head 38 and draws the catch and piston assembly back until the catch drops into position on the bar 34. Similar operation obtains when the nut approaches the end of its travel in the left-ward direction. The number of revolutions made by the motor between each reversal may be adjusted by altering the distance between the mountings for the limit switches 45 and 46. The shaft 5 may be coupled to the motor through a clutch which disengages on overload. The limit and reversing switches may be directly connected in the motor circuit, or may control contactors therein.

Abstract: 1356887 Fastener driving tool SOC FRANCAISE D'AGRAFAGE INDUSTRIEL 7 July 1972 [9 July 1971] 32002/72 Heading B4C A hand-operated fastener driving tool comprises a fastener driver 7 movable against bias of a spring (not shown) away from a fastener to be driven by clockwise pivoting of a lever 12 effected by application of pressure on a pivoted handle 16. When projections 13 on the lever 12 become disengaged from the driver, the latter will be driven by the spring towards the fastener to be driven. The tool includes a slidable plate 20 which may extend into or be withdrawn from a fastener driver blocking condition. When blocking of the driver is desired, a bar 31 is moved to the position of Fig. 3 so that a spring 30 will via a pivoted member 25 cause the plate 20 to move to the blocking position. The blocked driver will only be released to complete a fastener driving stroke upon application of pressure on part 26 of the member 25. With the bar 31 moved to the position of Fig. 4, the spring 30 will cause the plate 20 to be held in a non-blocking position, so that the tool will be operated only by depressing the handle 16. Movement of the member 25 relative to journals 15 such that the latter are positioned in notches 40 will remove portion 24 of the member 25 from slot 23 in the plate 20 to permit removal of the latter. The driver 7 will impinge against a resilient shock absorbing block (not illustrated) at the end of a fastener driving stroke.

Title: Process for obtaining metals from bituminous ores
IPC: C22B1/14
Filed: 1929-10-23
Abstract: In obtaining metals from bituminous ores the ore is heated with exclusion of air whereby the bitumen is distilled and may be recovered in the form of gas and oils, whereupon the residue is concentrated on high-speed percussion tables, or by colloid concentration.  The ores, preferably finely granulated, are treated at a temperature of about 500 DEG  C., i.e. slightly above normal low temperature distillation but the temperature may be raised to above 600 DEG  C. but kept below the normal reduction temperature to liberate wholly or mainly the metals from the compounds in the ore. The heating may be carried out in the presence of a catalyst such as gypsum.  The concentrates may be p  further treated in the anodic chambers of an electrolytic bath. Containers for the concentrate to be treated are formed by dividing the bath by porous plates and suspending the cathodes in the containers.  Electrolytic copper may be obtained directly from the concentrate.  If metal first obtained is impure, the various metals may be separated in succession by electrolysis.  In an example, Manfeld copper shale reduced to grains of 3 to 4 mm. and distilled at 600 DEG -700 DEG  C. yields fine threads of pure metal. Silver, lead, and iron are similarly obtained; the zinc ore remains unchanged as sulphide.  The metals, oxides, and sulphides are separated on percussion tables.
