Title: Improvements in coin-freed automatic machines
IPC: G07F11/62
Filed: 1928-05-02
Abstract: 318,560. Haustrup, N. J. May 2, 1928. Delivery of articles stored in separate compartments.-A coin-freed machine comprises a casing 1, Fig. 1, having a series of compartments 2 each of which has a fixed bottom 3 to support the article for sale, the article being surrounded by an inverted cylindrical member 5 made entirely or partly of glass or other transparent material. The member 5 is rotatable about a central axis 6 and has an opening 9 through which the article can be withdrawn, when the member is rotated by a, handle, 10 after being unlocked by the insertion of a coin. The members 5 project beyond the front wall 7 of the casing as shown in Fig. 3. The members 5 are normally prevented from rotation by wedge-shaped bars 17 abutting against rollers 19, 20 on vertical spacing bars 12 ,arranged in line and resting on a fixed abutment 13. The bars are prevented from moving upwards by a dog 16 engaging a locking element 15. When a coin is inserted, one of the members 5 can be rotated and the bar 17 thereon passes between its cooperating rollers 19, 20 thereby moving all the bars 12 above it upwards, while is prevents the bars 12 below it from moving. This upward movement obstructs the bars 17 of the members 5 above the one rotated, thereby preventing more than one member 5 from being rotated at a time. Coin action, with stationary coin forming abutment.-A coin 23, Fig. 5, inserted through a shoot 22 comes to rest between a, guide 25 and a screw 26 on the dog 16, the screw being adjusted according to the size of the coins used. The coin prevents the dog from engaging a notch 14 in the element 15 as this is being moved up. The coin is released when the dog strikes an inclined surface 28. Fraud, preventing; testing coins. - The coins pass from the channel 22 to a zig-zag channel 31 which prevents operation by a coin attached to a thin thread. An opening 33 in the channel 22 discharges coins of too small a diameter. The channel 22 is composed of two flaps hinged together 35, the hinged flap having an arm 39 which is actuated at each operation of the locking element 15 to open the flaps and discharge coins stopped in the testing channel. Such coins are returned to a trav 44. The distance between the flaps, when closed, is adjusted by screws to test for coins that are too thin.

Filed: 1929-04-26
Abstract: 330,082. Hasse, W. April 26, 1929. Moulding electric battery elements.-In a press for producing electrodes with protruding carbon, for galvanic elements, prepressing and pressing moulds and the devices for inserting the carbons are disposed coaxially in several sets arranged side by side, the moulds being stationary. Quantities of depolarizing paste are portioned off by a charge-graduating device 14 and supplied to the prepressing moulds 2, 2<a> through a feed pipe 15. Feeders 16, 16<a>, Fig. 3, prevent the paste adhering to the walls of the mould and the paste is prepressed by rams 5, 5<a>, of concave shape corresponding to the shape of the block to be produced, and operated from a cam disc 19 through levers 17, 18. The prepressed blocks are moved into the pressing moulds 1 by rams 3 actuated by a cam disc 6 and the carbons are then pressed into the blocks by devices 4, 4<a> operated by a cam disc 7. Rams 8 surrounding the carboninserting devices are then operated by cam discs 9 to compress the electrodes to the correct length whereupon they are ejected from the moulds by the rams 3 on to a conveyer belt and carried away from the machine. Superfluous paste squeezed from the prepressing moulds is received in a container 52. The charge-graduating device 14 comprises an intermittently rotating receptacle 37 having its bottom provided with holes 42 adapted to contain the required amount of paste and to register during the periods of rest of the receptacle with two holes 44 in a disc 43 arranged above the feed pipe 15. Fixed guide plates 47 within the receptacle cause the holes 42 to be filled with paste and wipe off superfluous paste. Rams 45 above the holes 44 and connected with the operating mechanism of the prepressing apparatus are then moved to eject the paste from the holes 42. The carbon-inserting device comprises a hopper 20, Fig. 4, in which operate reciprocating feeders 24, 24<a> actuated by a cam 21, the hopper being closed at the bottom by slides 27, 27<a> controlled by arms 28, 28<a> connected with the feeders. The carbons 26 are fed into spaces between the feeders and a central member 25 with a sloping top, and on outward movement of the slides 27, 27<a>, partitions 30 fixed to the inner ends of the slides take between the lowermost carbons and those above them, the separated carbons falling through slots 29, 29a in the slides into slotted sleeves 31, Fig. 5. A ram 34 operated by the cam 7 then moves a rod 33 axially in the sleeve 31 to force the carbon into the block in the mould 1. The rams 8 are divided longitudinally for cleaning and the cams 6, 7, 9 are disposed in oil-containing casings 35.

Title: Improvements in and relating to the manufacture and production of artificial threads, filaments and the like
IPC: C04B35/49
Filed: 1935-05-03
Abstract: <PICT:0456137/IV/1> Artificial filaments, threads, and the like having practically the same dyeing properties on the inside of the cake or bobbin as on the outside are obtained by a wet spinning process wherein the filaments are drawn through the spinning bath at a constant rate by a godet rotating at constant velocity and then round the periphery of a conical roller rotating at constant angular velocity, while the path of the filaments and the roller are caused to move relatively to one another in a direction parallel to the axis of the roller so that the speed of the filaments is progressively and gradually increased during substantially the whole of the time during which the bobbin or cake is being formed. The periphery of the conical roller may be curved so that the tension exerted on the filaments may increase more rapidly towards the end of the spinning operation.  As shown, a thread T is led from the nozzle through the precipitating bath on to a positively driven constant speed godet G, then on to a rotating conical roller A.  It also passes over a fixed guide L which keeps its path stationary in space while the roller A moves laterally.  The thread finally passes to a guide funnel K leading to a centrifugal box.  The conical roller A is rotated by a wheel C.  The spindle B slides axially, its position being controlled by rocker arm D and spring H.  The roller A is set in the starting position by pulling the lever J forward.  When spinning is commenced the rocker arm moves slowly to the right and the conical roller is pushed outwards.  The speed of shaft E is adjusted so that the conical roller A reaches the end of its travel when the cake or bobbin of thread is completed.

Title: Process of hydrolysis of starch
IPC: C13K1/06
Filed: 1945-05-26
Abstract: Dextrose is obtained by hydrolysing a starch suspension with acid under heat and pressure, neutralizing with an inorganic base which reacts with the acid to form a salt which is insoluble in the hydrolysate, removing the salt, concentrating the solution and crystallizing out a substantial portion of the dextrose.  The residual solution containing the reversion products is added to a new starch suspension for similar hydrolysis.  The preferred reagents are sulphuric acid and lime since the resultant calcium sulphate is collected on the filter which may be bone char. the pH being kept at 4- 5.5.  After revivification the char is treated with dilute hydrochloric acid before re-use. Specification 531,093 is referred to.
Patent GB-755461-A (GB)
Title: Improvements in or relating to sulfation of amylaceous materials
IPC: C08B31/06
Filed: 1954-05-06
Abstract: A sulphated amylaceous product is obtained by reacting an amylaceous material in the presence of at least 10 per cent water, based on the anhydrous amylaceous material, and sufficient alkali to achieve a pH of at least 9, with a reagent comprising the addition product of sulphur trioxide and a tertiary amine.  The term "amylaceous material" includes starches obtained from corn, wheat, tapioca, waxy maize, sago, potato, sweet potato, and rice. The starch may be in its native state or it may have been converted by heat, acids, oxidizing agents or other chemical means to thin-boiling starch, dextrin, starch ethers, esters or other derivatives.  The sulphur trioxide-tertiary amine addition product may be obtained by mixing the two components, or by reacting a tertiary amine with chlorsulphonic acid.  The trimethylamine-sulphur trioxide addition product may be made by reaction of dimethyl sulphate and tetramethyl sulphamide.  The tertiary amine may be aliphatic, aromatic, aryl aliphatic or heterocyclic.  Suitable amines are trimethylamine, triethylamine, tripropylamine, tributylamine, N-ethyl morpholine, N-methyl morpholine, dimethyl benzylamine, diethyl benzylamine, methyl diethylamine and pyridine.  The starch may be suspended or dispersed in water during the reaction, or the process may be effected on dry starch provided the reaction mass contains at least 10 per cent water.  The alkali used may be an hydroxide or weak acid salt of an alkali metal or alkaline earth metal or a quaternary hydroxide.  Thus, sodium, potassium or calcium hydroxide, trisodium phosphate, sodium carbonate or quaternary ammonium hydroxide may be used.  The reaction may be effected at room temperature or with heating and agitation.  The product may be neutralized to remove excess alkali.  The product may be obtained in ungelatinized form by avoiding gelatinizing conditions, e.g. excessive heat or alkali, or by adding sodium sulphate.  Alternatively gelatinized starch may be used initially or gelatinizing conditions may be employed.  The sulphated starch product dispersion may be used as such, precipitated by pouring into alcohol, or dried, e.g. over heated drums.  The amount of the sulphur trioxideamine addition product used may vary from 0.1 per cent to 450 per cent by weight based on the starch. Detailed examples are given in which corn starch in native form, reacted with epichlorhydrin, oxidized with hypochlorite, acid converted or acetylated, is reacted in the presence of sodium hydroxide or phosphate with a sulphur trioxide-tertiary amine addition product as described.
