Title: Method and Apparatus for the Activation of an Electrolytic Cell
Inventor: DILLER ISAAC MENDEL
IPC: C25C3/06
Filed: 1967-04-03
Abstract: 1,193,981. Electro-winning aluminium. I.M. DILLER. April 3, 1967 [April 4, 1966], No. 15071/67. Heading C7B. A method of activating a fused salt, i.e. subjecting it to the application of energy which induce strains in the fused salt to produce a lasting increase in its conductivity, so as to increase the yield of metal per kWh for a given rate of production when the salt is employed in the electro-winning of aluminium, comprises applying to the fused salt a level of neutron bombardment or radiant energy to induce strains in the crystal structure of the fused salt which raise the fused salt above the threshold strain level. The neutron bombardment or radiant energy may be applied discontinuously in one or more pulses. As described the fused salt is cryolite alumina, electrolyzed at 1000‹ C. With neutrons, activation may be effected by applying to 0À1% of the melt surface 3Î10<SP>16</SP> n/sq. in.; with γ-rays a cobalt source may be used to provide 3Î10<SP>9</SP> R; while with visisble light a hole is made in the melt crust and a xenon flash of intensity 5 MW/sq in and duration 10 Á secs. or a ruby laser pulse of about 10<SP>6</SP> times this intensity and a duration of 10 nanosecs may be employed. Activation with x-rays may also be effected. The activation may be effected in the electro-winning cell or in a separate container of molten salt which is used to seed the melt of an electrolysis cell as in Specification 1, 072, 890. Activation using both radiant energy and electric pulses may be employed, typically employing light to bring the molten salt to a subthreshold state and producing a persistent activation by means of electrical pulses, especially to produce successive upgrading of the activated conductivity as in Specification 1, 071, 441. In such a process, 2%by weight of varium oxide, titanuim oxide or barium titanate may be added to the melt to increase its dielectric strength and so reduce the risk of unintentional breakdown with destruction of activation due to accidental application of energy above the maximum determined by the strength of the melt.

A smokers' ashtray comprises a bottom part 9 surrounded by a housing 1, 2, and a centrifugal disc 4 with an unbroken exposed upper surface accommodated in the housing and mounted on a spring-loaded vertical screw spindle 7. The housing 1, 2, is vertically slidable on the bottom part 9 together with the disc 4 and spindle 7. The spindle 7 is loaded by a spring 21 in a sleeve 8 at the upper end of which are mounted balls 17 in a cage 16 which engage in a groove 10 at the top of the spindle 7. The part 2 of the housing has an extension 3, surrounded by a spring 22, inside which are teeth 14 which engage helical tracks in the spindle 7 through slots 13 in the sleeve 8. The teeth are also provided with noses 20. Upon depression of the housing 1, 2 the springs 21, 22 are compressed and balls 17 engage the groove 10 so that upon release of the housing 1, 2, the disc 4 is retained. When the noses 20 engage abutments 19 on the cage 16 the balls 17 are released from the groove 10 so that the centrifugal disc rotates upwardly under the action of the spring 21. In a second embodiment (Figs. 3 and 4, not shown) the disc 4 rotates when moving downwardly and is so moved by one of the ends of two pivoted levers which bear on a spring-loaded disc attached to the bottom of the spindle 7. The other arms of the levers bear on shoulders provided in the bottom part of the ashtray and the levers are pivoted on the bottom of the vertically movable housing part 2.

Filed: 1939-05-25
Abstract: 530,689. Dartboards. BENSON, B. S. May 25, 1939, No. 15499. [Class 132 (iii)] A dartboard adapted to indicate the score automatically has the usual scoring sections which form the face of the board mounted so as to move back-when hit against a resilient, e.g. rubber, sheet 3, Fig. 1, and displace, each, a contact pin 4 against a conducting disc 6, each pin being wired to an associated scoring stud 9 on an insulating plate 8. A hit being made, contact on plate 6 energizes a solenoid 15 to rotate an arm 12 till the live pin 9 is found whereupon a magnet 18 on the arm locks the arm at the live stud, and breaks the main circuit, whereupon the arm is returned by a spring. Magnet 18 also energizes solenoid 7 to move plate 6 to restore the contact pin 4 to normal position. A metal plate 10 contacts all the studs 9 to pass current to a common relay which on being energized releases the plate 10 to isolate the live stud 9. The arm is fast to a squared shaft 21, Fig. 4, on which slides a pinion 22, driven by a ratchet wheel 22a and pawls so that it can be put in mesh with either competitor's scoring disc 24 when a magnet is energized on operating a push button. The scoring discs are actuated against springs which are controlled by magnetically controlled pawls and further pawls prevent scoring over the maximum for the game.

The top and bottom sheets are glued together along their edges with glue strips 19, 20; the longitudinal edges of the bottom sheet being folded over those of the upper sheet and being provided with tabs 151 for attachment to the wearer. During production the diaper longitudinal edges are folded twice to give the Fig. 4 form. To manufacture a preferred diaper a lower cellulosic layer is fed to a conveyor belt 58 Fig. 1B having spaced groups of perforations whereby a vacuum source pulls fibres from a fibre forming chamber at predetermined intervals to form spaced fibrous pads 16. These pads are covered with cellulosic layers and all of the cellulosic layers are embossed during passage through rollers 70, 71. Cutter 80 and anvil 81 provide transverse perforations at predetermined intervals and tension rollers 85, 86 tear the perforations such that separate absorbent cores are enclosed between the upper and lower top sheets 15, 19. Glue lines are formed by nozzles 121, 90. After the transverse and longitudinal seals have been made the longitudinal edges are folded to the Fig. 4 form by mechanisms 157, 162, 165 and the individual diapers formed by cutter roll 170. These diapers are folded as they are pushed down between conveyors 181 to a rack where they are formed into batches of predetermined number. The tabs 151 are attached via mechanisms 150.

Abstract: Calcium chloride liquors, obtained by reacting ammonium chloride with hydrated lime, obtained from acetylene production, in the distiltillers of an ammonia-soda process, are freed from sulphite and fluosulphate impurities by heating the hydrated lime before entry into the distillation system to a temperature between 323-400 DEG  C. to convert the fluosulphate to sulphides, admitting the lime to the distillation system and adding ferrous sulphate to the distilled to precipitate sulphides as ferrous sulphide. The sulphides are separated from the calcium chloride containing liquor and the liquor subjected to evaporation to obtain calcium chloride. The amount of ferrous sulphate added to the distillers is from 5-20% excess over that stoichiometrically equivalent to the total sulphide present in the hydrated lime after heating. Specification 945,960 is referred to.

Suitable bath materials are Ma, K, Bi or Li. On completion of treatment the chamber is freed of metal vapour by closing valve 7 and condensing vapour on cooling element 10 through valve 11. Various heat-treatment temperatures can be obtained and controlled by adjustment of pressure above bath 8 between 0À1 to 5 atmospheres, preferably 0À5-1 atmospheres. Process applicable to large bodies where only surface layer requires treatment i.e. cold-rolls. Complex heat-treatments requiring multiple stages i.e. hardening and tampering, austempering or isothermal annealing of steels or solution treatment quenching and aging of non- ferrous alloys can be carried out in furnaces with multiple stages e.g. as shown in Figs. 4 and 5.
