Abstract: 1,141,758. Electro-dialysis. GENERAL DYNAMICS CORP. March 21, 1967 [April 6, 1966], No.13321/67. Heading C7B. A spent pickling solution containing alkali metal carboxylate such as sodium citrate, e. g. used for removing surface scale from stainless or alloy steel, is reclaimed by removing all the metals complexed in the solution e. g. Fe with or without Cr and/or Ni, preferably by adding NaOH to precipitate hydroxide, and electrolysing the remaining solution in a cell having at least one cation exchange membrane using an alkali metal hydroxide e. g. NaOH solution as catholyte and the remaining solution in the chamber adjacent the catholyte. The remaining solution may be fed into the central chamber of a three-chambered cell wherein H 2 SO 4  solution is used as anolyte Fig. 2 (not shown) or as anolyte in a two-chambered cell Fig. 3 (not shown). During electrolysis, oxygen is released at the anode, e. g. of platinized Ti, Pb, Pb alloy or graphite, and hydrogen at the cathode, e. g. of (Registered Trade Mark) "Monel" metal, and alkali metal ions migrate into the catholyte to form with OH ions generated therein additional alkali metal hydroxide which is withdrawn and replaced with water as needed. Alkali metal carboxylate solution of the desired acid PH, e. g. 1 to 7 for NaH 2  citrate, is withdrawn from the cell, preferably concentrated, for reuse in pickling.

Title: Circuit for selecting an extreme value
IPC: G01R19/00
Filed: 1973-03-21
Abstract: 1413228 Transistor circuit for selection of extreme value TELDIX GmbH 21 March 1973 [5 April 1972] 13602/73 Heading H3T In a circuit for the selection of an extreme value from at least two potentials present on different conductors a respective transistor 7, 7<1> couples each of the conductors to an output conductor by its collector-emitter path, the transistors have a larger amplification in the normal operation than in the inverse operation and the base-emitter paths of the transistors are connected to a potential so that the transistor conducting the extreme value is operated normally and the other transistor(s) is operated inversely. As shown the circuit is for use in an antilock controller for vehicle brakes. A signal of frequency proportional to wheel speed is fed from 1 via a frequency to D.C. voltage circuit 2 and a transistor 3 to charge a capacitor 4. The transistor 3 can be made non-conducting by means of a diode 6. Then a discharge of the capacitor 4 can only take place through the transistor 7 which discharge has a very large time constant. When the inversely driven transistor 3 is conducting and with reducing wheel voltage the capacitor 4 discharges with a lower time constant through transistor 3. A further capacitor 4<1> associated with another wheel is connected via a further transistor 7<1> to a common output which is connected to an operational amplifier 9. The larger potential say across capacitor 4 is coupled via the transistor 7. The other transistor 7<1> is then operated inversely so that a compensating current flows through it from the collector to the emitter. In further embodiments (Figs. 2 and 3, not shown) the smaller of the inputs is passed to the output. A still further embodiment is disclosed (Fig. 4, not shown) for finding a maximum peak.

Title: Method and apparatus for sheeting and curling dough
IPC: A21C7/01
Filed: 1953-05-15
Abstract: 733,266. Moulding dough. HANSEN, F. F. May 15, 1953, No. 13668/53. Class 87 (2). A continuous method of moulding loaves of bread dough comprises (i) subjecting dough to a sheeting operation while being advanced in a straight forward path, i.e. without reversal of direction, so as to arrange protein strands of the dough parallel to the line of movement; (ii) turning the still advancing sheeted dough through an angle so that the protein strands are transverse to the line of advancement; (iii) while maintaining the sheeted dough in the straight forward line of travel, curling it into a dough roll about an axis parallel to the transversely extending protein strands. A lump of dough 10 of a suitable weight for a loaf passes between pre-sheeting rollers 12, 14 and is deposited on two parallel moving belts 16 which carry it to a pair of sheeting rollers 22, 24 and in so doing turns it through approximately a right angle substantially as described in Specification 724,862. The dough is sheeted between the rollers 22, 24 and then between rollers 28, 30 in a direction transverse to the pre-sheeting operation, and as it is sheeted its surface is also ruptured, to improve the grain structure and to provide uniform moisture content, by a difference in the speeds of the sheeting rollers. After the sheeting the dough strip is turned again before being curled, or a pair of parallel moving belts 34 of such length that the dough has an opportunity to relax and contract, and is then carried by a belt 54 first under curling chains 56 and 58 which curl it into a roll and then under a pressurerolling board which comprises a series of triangular sections which elongate the dough from the centre of the roll towards each end, substantially as described in Specification 725,217. The rolls are delivered into pans carried on a belt 72, the speed of which is synchronized with that of the belt 54 so that a pan will move into position to receive a roll each time one leaves the belt 54. The rollers 22, 28 are flanged to control the width of the dough strip.

Title: Improvements in or relating to release mechanism for bombs and the like
IPC: F42B3/00
Filed: 1959-04-22
Abstract: 859,458. Dropping bombs and other articles from aircraft. BRODEN, E. W. April 22, 1959 No. 13704/59. Class 9(2). Mechanism for releasing bombs and other articles from aircraft, as in Specification 734,988, comprises a housing 11 fixed to the aircraft and united to a releasable member 10, which is connected to the bomb, by a sleeve 12 surrounding a piston 15, the piston being used to hold locking balls 34 in engagement with the member 10 until such time as the bomb is to be released. The piston, which bears against a spring 17 supported by a plug 18 secured in the sleeve 12 by a pin 20, has a through passage 26 housing an end of a lever 24. During transport, a pin 45 extending through the housing 11 locks the piston against accidental movement. Further locking balls 21, 22 housed in the piston are thrust into engagement with a groove in the sleeve 12 by a spring 23. To drive the piston and so release the member 10 and its load, a charge 29 is fired by a primer 28, which is electrically ignited. An expansion chamber 32 is provided between the cartridge housing 27 and the piston. Apertures 33 in the member 10 are of sufficient diameter to allow free passage to the balls 34 and have their axes inclined to the longitudinal axis of the sleeve at an angle α. Similar bores through the sleeve 12 are inclined at an angle #, which is greater than x. To prevent the balls 34 escaping an apertured holder 37 is secured around the sleeve 12 by the pin 20, the apertures being smaller than the balls 34. Support surfaces for the balls are also provided by the shaping of a flange 40 on the piston. On firing the charge 29, the thrust on the piston severs the pin 45 and displaces the piston, so that the balls 34 move inwardly and free the member 10. Spring 17 restores the piston to its original position and the balls 21, 22 engage the sleeve again, so that to secure a fresh load, the piston must be depressed by means of the lever 24.
