Title: Improvements in means for automatic regulation of flowing liquids or semi-liquids, especially wood-pulp
IPC: D21F1/08
Filed: 1933-07-19
Abstract: 404,883. Float - operated valves. AKTIEBOLAGET A. EKSTROMS MASKINAFFAR, 10, Vattugatan, Stockholm. July 19, 1933, No. 20363. Convention date, Sept 7, 1932. [Class 135.] In means for the automatic regulation of a liquid or semi-liquid, e.g., wood-pulp, in which a float controlled by the level of a stream of the liquid actuates a regulating device, a dam or checking device is provided in the stream so that variations in the level of the latter are caused solely by differences in the degree of concentration of the liquid. A pump 2 draws pulp from a vessel 1 and passes it into a box 4 in which the level is kept approximately constant by an overflow edge. An opening 8 leads to a channel 9 and a float 11 having a drag member 12 is supported by the stream flowing in the channel 9. A dam 10, Figs. 1 and 6, or other obstacle is inserted in the stream some distance from the opening 8 the purpose of which is to keep the level of the stream constant irrespective of slight differences in the level in the box 4. The float 11 is connected by a weighted lever 14 and rod 18 to a shaft 20 having a curved cam 21. A member 23 pivoted at 24 and continuously oscillated by a belt-driven crank 26 has catches 28 engageable with a friction disc 29, the catches 28 having rollers 22 which normally engage the cam 21 and hold them clear of the disc 29. The latter is geared to a chain-wheel 30 which is connected to the lever 33 of a valve 34. As the level of the stream varies the float 11 moves the cam 21 so that one of the catches 28 engages and moves the friction disc 29, the movement of which is transmitted to the valve 34, which, for example, varies the supply of water passing through a pipe 35 and into the pulp.

Fig. 4 shows the kind of record produced by the arrangement of Fig. 2. Several methods of tensioning the strip are described. Fig. 11 shows the general arrangement of the parts in a recording unit, which is detachably clamped on a base-plate 12. The light valve 8 is removably mounted and held by a fixing screw 11, so that it can be readily replaced by another, and the vibrating member is preferably enclosed in a protective casing. A greatly reduced image of the slots 1 is focused in the plane of the stop 2, a lens system 5 projecting a further image upon the record carrier such as a film.
Patent GB-717219-A (GB)
Title: Improvements in the production of oximes of cycloaliphatic ketones
Filed: 1952-08-15
Abstract: Cycloaliphatic oximes are prepared by introducing an alkali metal salt of a nitro-cycloalkane, preferably in the form of an aqueous solution, into an aqueous acid solution of a slight excess of a hydroxylamine salt, and separating the oxime formed, e.g. by neutralizing the acid reaction mixture to a pH value of 3 to 4. The nitro-cycloalkane may be nitrocyclohexane, -cyclopentane, -cycloheptane or -cyclo-octane.  The hydroxylamine salt may be formed by the reaction of sodium nitrite with sodium hydrogen sulphite.  The process may be carried out in a continuous process by pumping a mixture of the solution of the alkali metal salt of a nitro-cycloalkane together with aqueous acid solution of a hydroxylamine salt upwardly through a tower, and adding the necessary amount of alkali solution to the solution overflowing from the top of the tower, or to the solution in the upper part of the tower to adjust the pH value to 3 to 4.  Two detailed examples are given.

Title: Improvements in and relating to machine guns
IPC: F41A13/12
Filed: 1934-07-16
Abstract: 436,556. Machine guns. BRUCAR, L., 53, Rue Guza Voda, Bucharest. July 16, 1934, No. 20766. Convention date, Feb. 16. [Classes 9 (i) and 92 (ii)] The continuous operation of a multi-bore fixed-barrel machine gun wherein all the bores are discharged simultaneously, is effected partly by the action of the tapped explosion gases on a piston in a central cylinder, and partly by blow-back action on the breech-block. As shown, the barrel A is formed with six bores B around a central passage C constituting the operating- cylinder, and with lugs DR for attachment to a coupling-block K. The breech-casing RZ screws into the block K and the cartridges are fed in groups of six by mechanism G comprising a pinion N co-operating with a feed-rack on the cartridge-belt LM. The pinion N is actuated by a bevel-gear L on a spindle I, which carries a quadrant J arranged to co-operate with a rack GL on the breech-block O. The latter is guided in its movements along the sleeve RZ by balls T which are moved out of grooves in the sleeve to lock the breech-block in the firing position (Fig. 14). This locking movement of the balls is effected by the firing-member P which is moved from the cocked position to that shown in Fig. 14 by a spring S. The member P is fitted with six firing-pins and carries a spring-seated pin R which picks up the charge from an arm H on the spindle I during the forward movement of the breech-block under the reaction of a spring V. On the escape of gases into the cylinder C, the impact of the piston Z on the pin R causes the member P to recede within the breech-block thus freeing the balls T to permit the rearward travel of the block. To operate the gun, the breech-block is manually withdrawn and held by a trigger on the release of which the spring V reacts to start the continuous actuation.

Abstract: 257,295. Steimel, P. Aug. 22, 1925, [Convention date]. Automatic - feed weighers.-An . automatic-feed weigher for meal and like materials comprises a supply hopper 6 disposed above a weighbeam 3 and provided with a main feed gate 24 and dribble feed gate 33. A worm 7 in the hopper is adapted to feed the material into a sack 5 supported on the beam 3. The main gate is formed integral with a shaft 26 from which projects a hand lever 23. Upon the depression of the lever 23, as shown in Fig. 1, the main gate is opened and a clutch member 15 is caused to engage with a similar member on a continuously driven pulley 14, thereby causing the rotation of the worm 7 and of a stirrer 17. The gate 24 is held in open position by a catch lever 35. Upon the depression of a second hand lever 39, mounted on the shaft 26, the dribble feed gate 33 is opened and held in open position by a lever 37. As the weighing nears completion, a pendulous weight 38 causes the beam to tilt sufficiently to trip the lever 35 and allow the dribble feed gate to close. The final tilting of the beam closes the main gate. The speeds of the worm and stirrer may be adjusted by the use of stepped pulleys. A hand-operated valve 9 regulates the flow of material from the admission chamber 31.

Abstract: 579,182. Washing and drying machines. ELECTRIC HOUSEHOLD UTILITIES CORPORATION. Dec. 16, 1943, No. 21124. Convention date, Aug. 6. [Class 138 (ii)] A washing-machine of the kind having an oscillating agitator in a tub which after washing, is spun for centrifugal drying, is fitted with a reversible motor and gearing such that the washing agitator is operated for one direction of drive and drying is effected on the other. An agitator 31 and tub 25, Fig. 1, flexibly supported, for example, as described in Specification 549,629, [Group II], are operated by a motor 35 coupled to a shaft 38, 38b having a worm 66 engaging a worm wheel 67 integral with an eccentric 70 working in a block 72 sliding in a slotted arm 73 which is thus rocked to cause a segmental rack 79 to oscillate a pinion 80. This has a hub slotted at 82 so as to be movable into or out of driving mesh with a pin 83 on the agitator drive spindle 29. The pinion is grooved for engagement by a yoke 86 on a sliding rod 87 pivoted to a control lever 90, a spring 94 urging the pinion to idle position. On the reduced part 38 of the power shaft is journalled a worm 53 between a thrust bearing 54 and a shoulder 38a on the shaft, the worm at this end having a ratchet 55 forming part of a one-way clutch the other part 57 of which is secured to the shaft by a set screw 58 and carries the outer jaws 60, which provide pockets 61 for the balls 62 in the over-running position shown in Fig. 7. The hollow shaft 22 carrying the tub is journalled at 20 and 21 in the hollow standard 18 carried in a resilient mount 17 on a flanged neck 16 on the bottom of the tub casing and press-fitted in a neck 41 in the cover of the gear casing 44. In the shaft 22 is secured the hub of a pinion 64 which engages the worm 53 and is supported on a roller bearing 102 on a fixed bracket 88 carried by the gear case cover 40, which also supports all the gearing. The pump 117 may be driven by a pinion meshing with the worm 66 and being of the rotatable impeller type functions only during high speed centrifugal operation. The leads to the motor are through a three-way switch 106, Fig. 1, for " off," "wash" and "dry." When the switch is in the last position the lever 90 is moved to declutch the agitator drive. In a modification the lever 90 may be linked to the plunger of a solenoid in the circuit for the "dry" position so that the agitator drive is automatically cut out on drying. In a further modification both worms for wash and dry driving are loose on the shaft 38 which carries a double one-way pair of clutches so that the motor shaft drives the part appropriate to the setting of the switch.
