Class 39(3) [Also in Group XXX] Containers of paper, cardboard or the like which have been impregnated with paraffin wax or other hardening substance are transported through a cooling zone by an endless conveyer comprising members for carrying the containers and other members for guiding and driving the containers, all of these members consisting of continually or intermittently heated wires or cords. As shown, the conveyer comprises a plurality of pairs of parallel carrying cords 3 running on pulleys 5 and supported on stationary transverse wires 7 which have thickened portions 7<SP>1</SP> under the cords. The containers are fed by an air blast from a nozzle 2 on to the cords 3 which are supported at this point by an electrically heated plate 4, to place containers on each pair of cords. The cords are further heated where they are supported on the wires 7, by constructing wires 7 of heating wire, stretched by springs 8, and passing a current through them. This ensures that the containers do not stick to the cords and wax deposited on the cords is melted off. A further heated plate 6 is also provided on the return run of the cords for this latter purpose. The containers are guided laterally during travel by stationary longitudinal wires 20 also constructed of heating wire through which a current is passed, these wires being stretched by springs 21. The containers are also steadied by transverse wires 9 stretched between a pair of auxiliary chains 13 running over sprockets 12 mounted on driving shafts 16. The chains 13 and cords 3 are driven in synchronism from the shafts 16, the latter through belt gearing 17, 18, 19. The wires 9 are heated over part of their paths by current passed through them from a pair of bus bars 15 with which shoes 14 on the chains 13 make contact. The containers are discharged from the conveyer by an'air blast from a nozzle 24, the containers being steadied as they are turned into position opposite the nozzle by a notched wheel 22 engaging the bottoms of the containers in each row.

Patent GB-592631-A (GB)
Title: Cysteine and cystine
Filed: 1945-04-04
Abstract: Cysteine is produced by adding a thiocarboxylic acid to an alpha-acylamino-acrylic acid or a hydrolysable functional derivative thereof, e.g. a salt, amide, ester, nitrile, acid halide or acid anhydride and then hydrolysing the resulting N : S-diacyl cysteine or hydrolysable functional derivative thereof. The cysteine may be oxidized either simultaneously with the hydrolysis step or subsequently, to cystine.  The reaction may be carried out in an inert solvent such as benzene or ether or an excess of thio acid may be used as solvent.  Mild heating and the presence of a catalyst such as benzoyl peroxide or ascaridole are advantageous.  Any suitable hydrolysing agent may be used such as mild alkalies, e.g. alkali carbonates or alkaline earth oxides, acids, &c., but neutral or acidic conditions are preferred. Hydrolysis may also be carried out in aqueous or partiallyaqueous media, e.g. aqueous methyl alcohol. Suitable oxidizing agents are, e.g. oxygen, iodine, bromine, hydrogen peroxide and ferric sulphate.  Either of the two tautomeric forms of the alpha acylamino acrylic acid may be used.  In an example thio-acetic acid is added to alpha acetylamino acrylic acid, ascaridole being used as catalyst.  N : S-diacetylcysteine is obtained by refluxing the mixture and then evaporating under reduced pressure and is converted to cystine by hydrolysis with concentrated hydrochloric acid under oxidizing conditions using iodine in methanol. Cysteine may be isolated by carrying out the hydrolysis, e.g. with dilute hydrochloric acid and neutralizing the cysteine hydrochloride obtained.  Other thio acids such as thiopropionic, thiobutyric and thiobenzoic acids may be used.

Title: Improvements in or relating to submarine mines
IPC: F42B22/16
Filed: 1922-03-23
Abstract: 201,197. Vickers, Ltd., and Pratt, H. B. March 23, 1922. Mines, marine.-Relates to submarine mines of the kind comprising a mine proper, and an anchor or sinker containing a drum on which the mooring cable is wound, as also mechanism for varying the effective length of a plummet line as it is unwound from a drum, the plummet serving to free the mooring cable drum and allow it to pay out the mooring cable until the plummet touches bottom, when the mooring cable drum is locked and the mine submerged to a depth corresponding to the length of the plummet line. According to the invention, the plummet line is wound upon a reel located within the sinker and carried by or attached to a screw-threaded shaft which carries an adjustable device travelling along the shaft to a stop which determines the length of line paid out. Further, this device is adapted to release the usual devices holding the sinker to the mine. As shown, the mine B, Fig. 1, is held on brackets C on the sinker A by means of a hook v. The sinker contains a drum F, Figs. 4 and 5, for the mooring cable G and a reel H for the plummet line J, and is provided with rollers A<3> for launching the mine from rails. The plummet K is located in a chamber K<1> in the sinker and is suspended from an arm Y on a shaft e provided with another arm f connected by a rod g to a lever h cariying a roller j adapted to be engaged by the launching rails. When this roller leaves the rails, the plummet is allowed to drop under the control of a dash-pot Z connected to an arm f on the shaft e. As the plummet line is paid out of the reel H, the rotation of the reel shaft M, which is screw-threaded, moves a nut P' with an arm P along a channel-piece Q towards a collar R on the shaft. When the arm P leaves the guide Q, it bears on a spring lever S; and when the nut P<1> abuts against the collar R, the arm P deflects and swings past the lever S and strikes a lever T, which turns the hook v, releasing the sinker from the mine. The arm P then strikes a lever W, withdrawing a pawl X from a ratchet wheel F', allowing the drum F to pay out the mooring cable under the control of a gear oil-pump brake 1. When the sinker is released from the mine, a pin m is sheared or pulled therefrom, releasing weighted anchoring hooks k, which swing out and down until stopped in the best position by wires n. The length of plummet line paid out is determined by the initial position of the nut P' with its arm P. This is adjusted by means of a key which is inserted through a hole in the wall of the sinker to engage a notch in the shaft M and rotate the same, after a clutch member N has been withdrawn from the hole to disconnect the shaft M from the reel H. The plummet line is re-wound on the reel H by means of another key adapted to rotate the reel. When these adjustments have been made, the clutch-piece N is replaced against a spring and secured by a coverplate a<x>.

The driving shafts a<SP>1</SP>, a<SP>2</SP> of two counters A<SP>1</SP>, A<SP>2</SP>, Fig. 3, are driven from a unidirectional rotating shaft B through reversing gear comprising a bevel gear b on the shaft B and bevel gears c<SP>1</SP>, c<SP>2</SP> on a sleeve c slidably mounted on a short shaft C situated between the two shafts a<SP>1</SP>, a<SP>2</SP> and drivingly connected thereto. A plate G<SP>1</SP> pivoted on a pin g<SP>1</SP> and carrying a roller h located between shoulders on the sleeve c is connected by a pin and slot to a plate G also pivoted on the pin g<SP>1</SP>. The plate G has an arm g which is connected to the armatures f, f<SP>1</SP> of two electromagnets F<SP>1</SP>, F<SP>2</SP>. The last numeral wheel a<SP>3</SP>, Fig. 5, of each counter has a recess a4 which, when all the numeral wheels read " 9," comes opposite the end d of a pivoted lever D which then rocks clockwise to release a spring-operated plunger e of a micro-switch E which completes a circuit to one or other of the electromagnets F<SP>1</SP>, F<SP>2</SP> whereupon the armature for f moves the plates G, G<SP>1</SP> and the sleeve c to disengage the bevel gear b from the one and engage it with the other of bevel gears c<SP>1</SP>, c<SP>2</SP>. An electric bulb H or H<SP>1</SP>, Fig. 3, is illuminated upon movement of the associated lever D. In operation one of the counters A<SP>1</SP>, A<SP>2</SP> is preset to read one unit less than the number at which reversal of the counterdrive is desired and the other counter is preset to read " 999 ... ". The reversing gear is thereby positioned so that the first counter is driven backwards and the second counter forwards. When the first counter reads " 999 ... " i.e. when the desired number has been counted, the counter drive is reversed as above described. The operation of the microswitch F<SP>1</SP> or F<SP>2</SP> may cause reversal of a drive to a machine, bring into action alternately one or other of two machines and/or give a visible or audible signal. The shaft B may be rotated continuously if used in connection with a length measuring apparatus or intermittently if desired.
