Title: Method and means for turning cigarettes and like shaped articles when packing same
IPC: B65B19/06
Filed: 1929-04-13
Abstract: 331,806. Gottschalk, P., and United Cigarette Machine Co. Akt.-Ges. April 13, 1929. Divided on 331,603. Packeting cigarettes. - In feeding cigarettes to a packing-machine, those which are incorrectly placed are turned so that the imprints lie upwards. The cigarettes d are conveyed on the links a of a chain be neath a guide f, into contact with which they are raised by a spring g. If a cigarette is incorrectly placed, a finger i mounted on a spring h engages the longitudinal seam, and commences to turn it about its axis in an anti-clockwise direction. In the form shown, the spring h is pivoted to a lever r oscillated about a centre r<1> by a cam s against the action of a. spring t. The movements of the finger are arranged so as to catch the seam of an incorrectly placed cigarette and turn it so that the leading edge engages a check-piece n, which turns it completely over. In another form, the finger i may be similarly mounted, but is free to travel with the cigarette against the action of a light spring until arrested by an adjustable stop, upon which an auxiliary turning device such as a check-piece completes the movement.

Abstract: 1286373 Semi-conductor solar cells FERRANTI Ltd 19 April 1970 [14 March 1970] 12410/70 Heading HlK A solar cell is formed in a high resistivity P-type silicon semi-conductor wafer 11 by indiffusion of N-type region 12 adjacent the entire surface and covered by a passivating layer 13 of silicon oxide, the P-type region 14 being enclosed within region 12 and layer 13, which are lapped off at major face 15 to expose region 14 and the ends of region 12 adjacent the side walls. Face 15 is electroless coated with boron doped nickel 18 sintered to ohmic contact with regions 12, 14. Apertures 19 are etched photolithographically by buffered hydrofluoric acid in oxide layer 13, and surface contamination of layer 18 is simultaneously removed. A metal coating 20 of phosphorus doped nickel is electroless deposited in apertures 19 by reduction of nickel chloride by sodium hypophosphite, to contact region 12; and a layer of nickel 21 is also deposited on layer 18 entirely or in patterns defined by apertured photoresist, which may register with apertures 19; and photoresist is subsequently removed. Lead 22 is connected to layers 18, 21 and copper is electroplated on layers 20, 21 using current flowing from 22 over layer 18 and region 12. Gold coatings are then deposited on the copper layers 23, 24 to complete composite contacts 25, 26 for the regions 12, 14, Fig. 3. The ends of the device are broken away after sintering, Fig. 4, so that region 12 does not extend to face 15 and is isolated from contact 26. When coating 21 is patterned, the copper and gold coatings attach only to the coating and not to the exposed sintered layer 18. Region 12 may be diffused so that it does not extend to face 15, and contact 26 is removable in part from first region 12. Contact 25 on face 17 is divisible into plural discrete parts on sintering and breaking, or plural contacts may be formed as shown, using plural apertures. The first region may be divided into parts or further diffused after electroplating.

Abstract: 162,670. Mora, B. May 5, 1920, [Convention date]. Type-wheel machines for decoding; key actions. -In apparatus for translating code signs or signals, such as long and short flashes of light, or the waving of flags, into print, and having keys operated in accordance with the code sign or signal to adjust different types, the amount of movement of a type-wheel is determined by the adjustable limitation of depression of one and the same keys operated alternately or in succession. As shown in Fig. 1, three keys are employed, e for the dot, f for the dash, and u for release between each complete signal representing a letter &c. The keys e, f have tappets g, h, which engage one arm of a bell-crank lever b mounted loosely upon the type-wheel shaft. The typewheel a has a ratchet-wheel engaged by a spring- pressed pawl c mounted upon the lever b, a detent z holding the ratchet-wheel after movement. Another pawl i has a pin-and-slot mounting n, p upon the lever b which gives to this pawl a forward and upward movement in step with the key depressions. The downward movement of the keys e, f and consequently the rotation of the type-wheel is limited by pins l, m engaging with projections at different heights in a stop bar k. After each letter combination is completed the release-key u is depressed for impression as described below, and upon its return movement frees the detent z from the ratchet-wheel and also through linkage the detent m<1> from the stop-bar, the type-wheel and stop-bar being spring-returned to normal position. When used for transmission at the same time as recording, the keys may be provided with suitable contacts for making circuit with a battery and lamp. Instead of the keys operating directly upon the stop-bar, they may operate through a power device. Hammer-impression arrangements. - The release-key u upon depression rocks a two-armed lever o to press the paper-strip holder s against the ink-ribbon q and type-wheel.

IPC: C01F11/10
Filed: 1961-04-11
Abstract: Barium hydroxide crystals are produced from a 3-13% by wt solution of barium sulphide by cooling the solution to a temperature not below the minimum temperature defined herein to cause the formation of barium hydroxide-containing crystals, passing a stream of said crystals into a washing zone cooled at least sufficiently to prevent any substantial dissolution of the crystals, passing through the washing zone a stream of water or aqueous barium hydroxide solution to decrease the impurity content of the crystals and removing the washed crystals and associated liquor from the washing zone.  The wash liquor is preferably passed countercurrent to the barium hydroxide crystals.  The crystallization and washing steps are conducted in two zones of a single column-like vessel under isothermal conditions and a wash stream of barium hydroxide which saturated at the temperature at which the crystals are to be washed. The ratio of volume of wash liquor occluded with the crystals issuing from the washing vessel should be greater than one.  The minimum temperature of crystallization from any barium sulphide solution must be above that at which barium sulphide can precipitate. Specification 980,812 is referred to.
