Title: Improvements in and in connection with the process and method of production of separators, diaphragms, filters and the like consisting of porous, or porous and non-porous soft to hard rubber and the like
Filed: 1928-12-20
Abstract: 328,274. Wilderman, M. Dec. 20, 1928. Moulding ebonite diaphragms for filtering etc.; endless-chain moulding-machines; reciprocating- mould-table machines.-The invention relates to a method of making porous ebonite, and like bodies such as separators, filters, diaphragms, &c. by a process as described in Specification 328,273, [Class 70, Indiarubber &c.], when the particles are spread into and vulcanized in foil moulds.. The process comprises maintaining particles of partially vulcanized rubber during spreading into the lower foil moulds at such a temperature as to avoid sticking together, compressing the spread particles to porous bodies and supplying the top foil, and then vulcanizing at such a speed as to get strong bodies. The separators &c. may have ribs of non-porous rubber. Various machines for use in the process are described. Mechanism for spreading the powder into the moulds and compressing it is shown in Fig. Va. Spreaders 5 the temperature of which can be controlled are mounted on a framework 9. The tables a carrving the steel mould 7 in which is the lower foil mould, remain stationary under the travelling spreader while the powder is being spread into the foil, the spreading action being controlled by cam rails coacting with rollers on the spreader. When spreading is finished, the table carries the lower mould into the press 1 containing the upper steel mould 3 which holds the upper foil and the upper foil is pressed on to the lower foil, sealing being effected by a frame of non-porous rubber contained in the lower foil. Alternative spreading mechanisms are described in which the spreader remains stationary while the moulds pass underneath. The spreader shown in Fig. VIIa consists of a hopper 1 and a bottom piece 2 both containing stirrers operated by shafts 6, 7 and 8. The spreader is heated by means of plates 13 carrying electric heaters. The bottom of the spreader is fitted with a slot piece 20 containing slots 21 through which the'particles emerge. The opening and closing of the slot is controlled by the rocking lever 23 operated by the cam rails through wheel 25. 'When separators containing ribs of non-porous rubber are used, a frame of rubber is placed in position in the lower foil before spreading. In a press as shown Fig. VIIIa for placing these frames, the foil carried in a steel mould d is fixed on a heated plate c. The frame of rubber is placed in position over the cores h and plate c made to move towards the cores so that these just enter the shaped foil mould. A cooled plate f with projecting sleeves carrying a stripping plate g then moves forward pressing the frames on to the foil to which they adhere. Vulcanization is carried out by placing the foils between plates 7 representing the negatives of the foils, in a vulcanizing press, Fig. IXa, heating plates 9 being inserted at intervals.

Inventor: PALMER AUSTIN RICHARD
IPC: A21C3/00
Filed: 1958-11-27
Abstract: 883,626. Discharging moulded dough pieces. BAKER PERKINS Ltd. Nov. 25, 1959 [Nov. 27, 1958], No. 38278/58. Class 87(2). Dough pieces e.g. 21a in the moulding drum 4 of a dough moulding machine are discharged between a fluted roller 1 and moving surface means comprising, either a series of rollers 9-15, Fig. 1, or an endless apron 40, Fig. 5B, extending in an arc disposed over but spaceable from the upper peripheral part of the roller 1 at a distance corresponding to the diameter of a moulded dough piece, the fluted roller or the moving surface means or both being driven at a suitable surface speed. As shown in Fig. 1 the small rollers 9-15 are free running and the dough piece passes through the position 21b and is discharged on to a conveyer 5, e.g. at 21c. The fluted roller 1 is driven by a chain 6 and gearing 7, 8. To allow for variations in size of dough pieces the framework 16 on which the rollers 9-15 are mounted is pivoted at 20, below the level of the lowest roller 15, being balanced by a counterweight 19, the normal working position being controlled by an adjustable stop 18. Fig. 3 shows an arrangement in which the fluted roller 1 and the small rollers 9a-15a are both driven, the latter from the chain 6 which drives the roller 1 by a sprocket wheel 30 engaging the chain and driving, through gearings 31, 32, a pulley 33 from which a belt 27a drives the last two of the smaller rollers 14a, 15a, the remainder 9a-13a having pulleys on their shafts which are all driven by a belt 28 from a pulley on the shaft of the roller 14a, tensioned by a jockey roller 29. The fluted roller may run freely and the small rollers may be driven from a motor, which also acts as the counterweight, through two belts in series, one driving the two end rollers and the other operating as the belt 28 in Fig. 3. Fig. 4 shows an arrangement in which the rollers 9b-15b all have friction discs 35 which are in contact with a friction disc 36 on the fluted roller 1, from which they are driven. An apron 40 may pass round the small rollers 9c-15c, Fig. 5B, and in contact with the roller 1, which is driven, so that a dough piece 21e is carried round between the roller and the apron, which is driven partly by its contact with the roller 1 and partly by the dough piece itself. A jockey roller 41 tensions the apron.

Title: An improved apparatus for controlling the mixing of a fluid in the form of a gas with a liquid
IPC: C02F1/68
Filed: 1960-11-08
Abstract: 923,313. Mixing fluids in flow. LANCY LABORATORIES Inc. Nov. 8, 1960 [April 22, 1960], No. 38297/60. Class 86. [Also in Group XXIX] An apparatus for supplying chlorine as gas in constant ratio to a substantially constant flow of water A comprises a Venturi mixing unit B and a gas regulating unit E which is attached to a pressure cylinder D containing partially liquefied chlorine. The carrier B, Fig. 8, has a valve member 78 carried by a diaphragm 80 and having an annulus 78a seated on a gasket 74 when the apparatus is inoperative, thus acting as a check valve to prevent backflow of water through the apparatus. The underside of the diaphragm 80 is subjected to reduced pressure induced by the Venturi 66, and is drawn downward so that the valve 78a, 74 opens and the foot of the stem 82 engages the floor of the valve chamber opening also the valve 81, 83 as shown, and placing the gas supply inlet 73a, 73b and hence pipe 61, Fig. 1, in connection with the Venturi. The pipe 61 is in communication with a bore 35d, Fig. 4, in the unit E, and thence via passages 54c, 48c, 48b, 35b, 23c and 23b with one side of a diaphragm 33 carrying a valve member 28 to which is attached the stem 26 of a plug valve 26a seating on a member 25 and shown closed in Fig. 4. Reduction of pressure induced by the Venturi deflects the diaphragm 33 and thus opens the valve 25, 26a and emitting chlorine from the cylinder D ; the rate of flow of the gas is regulated by needle valve 58 and measured by flowmeter 52. The gas pressure remains substantially constant until the cylinder approaches exhaustion; when the pressure falls below a predetermined level, diaphragm 33 will be deflected further until the annulus 28a seats on the gasket 27 interrupting the gas supply. At the same time a spring- pressed pivoted signal arm 40 (see Figs. 2, 5, 6, 10, 11 and 12 (not shown)) is released by withdrawal of a stud 38, which is secured to the tail of the valve stem 26 and projects beyond the face of the unit E to act as a detent. Any excess pressure of gas reaching the unit B will deflect the diaphragm 94 to lift the annulus 92a of valve member 92 off its seat 75 and vent the gas to atmosphere through a central aperture in the disc 95, and the outlet 88b. As the spring 96 is weaker than the spring 85 controlling the diaphragm 80, the valve 78a, 74 will remain closed.

Title: Confection stock comprising carboxymethyl dextran
Inventor: NOVAK LEO J
IPC: A23G3/34
Filed: 1957-12-10
Abstract: Carboxy methyl dextran for use as a substitute for sugar in fudge (see Group VI) is obtained by acting on the selected water-soluble native linear or substantially linear dextran with a carboxymethylating agent in an aqueous alkaline medium so as to substitute carboxymethyl groups for one or more hydroxyl groups in the dextran molecule.  Suitable agents are chloracetic acid, sodium chloroacetate or chloracetamide used in an aqueous solution of a strong alkali metal hydroxide e.g sodium, potassium or lithium hydroxide.  Preferably the dextrose is treated in aqueous solution or suspension with an excess of sodium or potassium chloracetate in the presence of sodium or potassium hydroxide at a temperature of 50 DEG C. to 100 DEG C. for 10 minutes to 2 hours.  The molar ratios are preferably:-potassium chloracetate: dextran between 2:1 and 12:1, sodium hydroxide: dextran between 5:1 and 15:1 and water: dextran 70:1 and 120:1. The salt is precipitated by a water-miscible alcohol or a ketone. The free ether is recovered by mixing the salt with water, acidifying to a pH of about 2,0 and precipitating the carboxy methyl dextran by adding an aliphatic water-miscible alcohol or ketone.  The dextran is produced by the action of Leuconostoc mesenteroides on sucrose in an aqueous nutrient medium containing also inorganic salts and is then precipitated and purified.ALSO:A dry confection stock, adapted to be mixed with water and cooked to produce fudge, comprises granulated sugar and a carboxy methyl ether of a nature, water soluble substantially linear dextran containing 1,5 to 3 carboxy methyl groups per anhydro glucose unit, 5 to 50% less sugar than normal being used.  The mixture usually includes the carboxy methyl dextran and granulated sugar, powdered whole milk, cream, vanilla and cream of tartar. Marshmallow may be added if desired.  The carboxy methyl dextrans are produced from dextrans (see Group IV(a)).  A chocolate fudge may be made from the following ingredients:- .Carboxy methyl dextran.10% .Water.30% .Sugar.40% .Powdered whole milk.5,3% .Powdered skim milk.2,3% .Powdered wasted milk.2,3% .Powdered cream.0,7% .Vanilla.0,2% .Cocoa.9,2% .Cream of tartar.0,2%  The mixture is dry as the water is absorbed by the carboxymethyl dextran and is placed in a packet along with a separate packet containing marshmallow.  In use cold water is added to the mixture which is heated while being stirred until it boils after which it cools.  The marshmallow is then added and the mass is beaten vigorously after which it is allowed to set. Chopped nuts, cocoanut or the like may also be added.
Patent GB-1343711-A (GB)
Title: Method and apparatus for locating movable objects on a fixed path
IPC: B61L25/02
Filed: 1971-08-17
Abstract: 1343711 Position determining COMPAGNIE GENERALE D'AUTOMATISME 17 Aug 1971 [17 Aug 1970 21 May 1971] 38506/71 Heading G4H A system for determining the position of an object on a fixed path comprises marks arranged alongside the path to define successive path sections and to define binary digits "0" or " 1", the set of marks defining at least part of a pseudorandom binary sequence, a detector carried by the movable object, an m-stage shift register linked to the detector to receive the successive bits and to hold them in successive groups of m which groups are all different according to the predetermined properties of the sequence and which each signify a respective position of the object, circuitry for detecting errors in the m-digits groups in accordance with the properties of the sequence, and inhibiting circuitry to prevent indication of a position in response to detection of an error in an m digit group. As an example, in a 7-bit series 1110010 which is repeated as necessary, 7 different 3-bit words may be formed by successive 3-groups of bits, i.e. 111, 110, 100, 001 ... &c. As shown, the inputs 21, 22 are detected at 24 and passed to a 5-stage shift register 26-30 as well as to a comparator 32, the other input of which is derived from two stages, e.g. 27, 28 of the register via an Exclusive- OR gate 31. It is shown that with given certain properties of the sequence, the output at 31 should equal the next bit detected at 24 and upon equality a binary "1" is emitted to a counter 41 adapted to count only "1"s, a threshold detector 42 being triggered after k counts to open a gate 46 to read out at 47 of the register the position of the object. Upon occurrence of a "0" at 32 indicating non-equality and therefore an error, the counter 41 is reset at 44 via inverter 43 and the gate remains inhibited. If n (in the simple case 3) is the minimum number of bits of a word such that all words taken in the sequence of bits are different, the difference is defined as k = m-n (in the example k = 2). Thus k is the number of bits whose parity is dependent upon the m digits of the word and it is stated that if no errors are found in k comparisons, the probability of further errors being present is small.
