Title: Improvements relating to weighing and packing apparatus
IPC: G01G13/00
Filed: 1946-07-22
Abstract: 628,472. Pneumatic conveyer and weighing machine. SMIDTH & CO. AKTIESELSKAB., F. L. July 22, 1946, No. 21858. Convention date, Nov. 13, 1941. [Class 78 (i)] A method of filling bags on a weighing machine of the kind in which powdered material flows to the bags from a tank 1 through discharge openings 5 distributed around the bottom of the tank, includes the step of bringing the material around the discharge openings into a fluid state solely by means of gas introduced into the tank through porous material 12, 13, 14 as a multiplicity of small streams in the proximity of each of the openings and permitting the material to flow through the openings solely under the influence of gravity. As shown, the tank is formed with porous sides 12, 13, porous conical bottom 14, and a porous ring 21 which is provided with discharge openings 5. Material is introduced through pipe 3 ; and compressed air is introduced through pipe 19 and passes out into the material through porous bottom 14, through porous ring 21 via holes 25, and through the porous sides via tube 20. The material thus impregnated with air passes out through discharge opening 5, rubber spout 6, and filling spout 7 into a bag over the'end 8. When the bag is filled to the correct weight the weighing arm 9 releases the gripper 10 by which the bag is held and the bag is ready to be removed, and also operates arm 18 to squeeze rubber spout 6 and thus seal the material outlet. The tank 1 may rotate on its axis 4, and the porous material may be felt, cloth or filter stone, or porous plates. Air may also be introduced in the filling spout 7 through porous plate 22 to assist discharge. The compressed air may be under uniform pressure or may be pulsating.

Title: A new or improved pre-digested vegetable foodstuff for animals and a process for producing the same
IPC: A23K1/00
Filed: 1937-01-11
Abstract: Ammonia gas given off during the fermentation of fish offal with seaweed by the action of thermophile bacteria in the production of a foodstuff for animals is recovered as a byeproduct as sulphate of ammonia.ALSO:A pre-digested and dehydrated food for animals containing iodine in organic combination is made by subjecting fish offal and seaweed to the action of thermophilic bacteria at such temperatures and for a period which will effect pre-digestion and partial dehydration of the mass and the organic combination therewith of iodine from the seaweed.  In an example, fish offal is mixed with macerated seaweed of the laminaria digitala type, introduced into a chamber, and sprayed with bacterial fluid containing both anaerobic and aerobic bacteria.  The chamber is then sealed and anaerobic fermentation is allowed to continue for about ten days.  Air or oxygen is then admitted and aerobic fermentation takes place, the temperature being allowed to rise to 75-80 DEG  C. to destroy the putrefactive organisms and to dehydrate the mass.  The thermophilic bacteria may be pure cultures or a bacterial liquid such as cow urine may be used.  The alkalinity of the mass for fermentation is controlled by the addition of calcium carbonate.  Ammonia gas given off during fermentation may be recovered as a bye-product as sulphate of ammonia.  Specification 487,837 is referred to.

Patent GB-614966-A (GB)
Title: Improvements in and relating to the treatment of wool
IPC: D06L4/10
Filed: 1946-07-24
Abstract: Textile material, composed wholly or partly of wool or of other animal fibres, is rendered resistant to felting and shrinking, when washed in aqueous liquids, by impregnating it with a compound of copper, nickel, silver, or mercury, and subsequently impregnating it with a solution of a peroxide or peroxy compound, e.g. a peroxide of hydrogen, alkali-metal, or alkaline earth metal, or a perborate or percarbonate of an alkali metal.  The wool material may be in the form of loose fibres, slubbings, tops, roving, yarn, knitted or woven fabric, or garments.  It may be treated in oily state or after scouring.  The metal compound greatly increases the shrink-proofing effect of the peroxy compound.  When cellulosic fibres are present with the wool, it is preferred to use a nickel compound.  The proportion of metal compound required is very small and may be as low as 0.001 per cent for copper or nickel, 0.03 per cent for silver, and 0.05 per cent for mercury based on the weight of wool.  The solution of peroxy compound may be used at a pH of 3 to 10.5.  The treatment may be used to effect a bleaching of the materials as well as shrink-proofing, and it is then preferred to use a copper or nickel compound and to carry out the treatment with the peroxy compound under alkaline conditions.  A final treatment with acidified sodium bisulphite solution may be given to assist in removal of the metal compound from the fibres and to enhance whiteness of the material. In an example, wool fabric is impregnated with a very dilute solution of copper sulphate at 75 DEG  C.  The fabric is removed and a mixture of hydrogen peroxide and sodium silicate is added to the liquor which has been cooled to 50 DEG  C.  The fabric is again entered in the liquor and treated for an hour.  It is then placed in water containing a small proportion of sodium bisulphite and sulphuric acid, and then washed and dried.  In other examples, nickel sulphate, copper acetate, silver nitrate and mercuric acetate are used for the pre-treatment, and sodium perborate and sodium percarbonate are used for the peroxy compound treatment.  When using hydrogen peroxide, the pH may be adjusted by means of tri-sodium phosphate, sodium acetate, or tetra-sodium pyrophosphate.

Title: Improvements in rotary engines
IPC: F04C2/16
Filed: 1935-10-16
Abstract: 464,494. Meshing - screw engines. AKTIEBOLAGET MILO. Oct. 16, 1935, No. 22337 /36. Convention date, Oct. 16, 1934. Divided out of 464,475. [Class 110 (ii)] The engine or compressor comprises two or more screws 12, 14, one rotor 12 of a pair having threads which extend into helical recesses in the smaller rotor 14, there being no contact between the rotors, which are not lubricated. The pitch circle coincides with the outer circle of the rotor 14. The rotor shafts are geared together at the delivery end by gears 42, 46, which, preferably, have helical teeth. The L.P. end of the apparatus (when used as a compressor) is sealed by labyrinth packing rings 58, to which fluid from the H.P. end is led by way of an inlet 66. This fluid exerts a pressure to the right on a disc 60, to counterbalance the axial thrust on the delivery end of the rotor. A similar packing and balancing arrangement 113, is provided on the suction end of the second rotor. Oil throwing rings 48, 50 at the L.P. end, and 54, 56, at the H.P. end, prevent leakage of lubricant supplied to the bearings. Similar rings are attached to the second rotor shaft. Cooling liquid for the rotors enters tubes 76, 118, by way of nozzles 84, 86, flows to the left-hand end, and returns outside the tubes to a space 94 having an outlet 96. The space 94 is screened from the bearings 40, and gearing, by a partition 97. The casing has a cooling jacket 124. Fluid under pressure (after being cooled) is led through a tube 122, to the space 120, to prevent heated delivery fluid from leaking in from the compressor. Means to secure compression in the compressor comprises a narrowing down of the outlet orifice by inserted plates 142, 144, which may be slid outwards by spindles 150, 160, to alter the outlet area. Inset pieces 164, 162, prevent turbulence of the fluid passing to the outlet 130. Specification 464,493 is referred to.

Abstract: 909,185. Semi-conductor devices. PYE Ltd. June 28, 1961 [June 29, 1960], No. 22778/60. Class 37. [Also in Group XXII] In punching a pellet from a piece of impurity material on to the surface of an element of semi-conductor material, a strip of material which prevents impurity material from sticking to the punch is interposed between them. As shown, in making a PNP transistor, a piece of tissue paper 3 is interposed between an indium tape 1 and a punch 2 while a pellet 4 of indium is punched on to one surface of a wafer 5 of N-type germanium, which is then inverted to receive a second pellet on its opposite surface; alternatively, a second punch may be located below the wafer. The assembly is then heated to alloy the pellets to the wafer. The material of the strip may be of thin sheet plastic or it may provide a small percentage of an element which improves the emitter efficiency, e.g. a separate strip of aluminium, or a coating of aluminium on the indium tape, is used. The invention is applicable to the making of NPN transistors and semi-conductor diodes ; the semi-conductor material may be silicon.

Abstract: 362,471. Spray carburetters. FORD MOTOR CO., Ltd., 88, Regent Street, London. July 30, 1930, No. 23014. Convention date, Aug. 28, 1929. [Class 7 (iii).] In a control device wherein a control rod is formed with a lap joint which transmits rotary movement of the rod to a fuel needle valve, and allows the rod to be reciprocated to actuate an airchoke valve, the control rod is formed with another joint, the two parts of which are normally held together by a sleeve member which may be moved to uncover the joint and permit the parts to be separated. The carburetter consists of an upper portion 10, Fig. 3, and a lower portion 11 to which air from a heating or filtering device is supplied through a pipe 38 provided with a choke valve mounted on an axle 40. The fuel control valve 68, Fig. 4, is mounted in a lateral extension of the casting 11 and is screwed through a bush 75 closing a well 74. The upper portion of the needle valve is of half-round form to engage a similar portion of a rod 81, the lapping portions of the needle and rod being enclosed in a sleeve portion 78 extending from the bush 75. The rod 81 is connected to the control rod 80 through an S-shaped joint 88 which is encircled by a sleeve 90 forced against a sleeve 82 by a spring 91. The sleeve 82 surrounds the sleeve 78 and is pinned at 83 to the rod 81. The sleeve 82 has at its lower end a pair of collars forming an annular groove with which engages a roller 85 on a lever 86 mounted on the axle 40 of the air choke valve. The rod 80 extends through the dashboard 89, Fig. 3. Rotation of this rod adjusts the fuel needle valve 68 and, in any angular position, it may be reciprocated to adjust the choke valve. By pulling up the sleeve 90 the joint 88 is readily broken and the parts dismantled. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following :-The parts 10, 11 of the carburetter are secured by a single bolt 12, Fig. 2 (Cancelled), and a cup-shaped portion 15 of the part 11 forms the float chamber which contains the pivoted float 16. The float valve 22 seats in a bush 23 screwed into the part 10. The fuel duct 24 contains a filtering screen 28 carried by a shank 27 with hexagonal head 25. A Venturi tube 51 has at its lower end a shoulder 52 slotted to receive arms 54 of an inner Venturi 55. The Venturi tubes are secured in the act of screwing up the bolt 12. Fuel is supplied through two nozzles 57, 62 of which 57 is supplied in the usual manner from the float chamber, 62 being fed from a well the level in which falls as the speed increases. Nozzle 62 may also receive part of its supply through a needle valve from the passage leading to nozzle 57. The well also supplies an idling nozzle delivering near the edge of the throttle valve 41, when closed, through a duct 72. A manually adjustable screw serves to control entry of air to a mixing chamber surrounding the delivery end of the idling nozzle. This subject-matter does not appear in the Specification as accepted.

Title: Arrangement for bridging line equipment in communication networks

Filed: 1974-05-23
Abstract: 1458626 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 23 May 1974 [7 June 1973] 23049/74 Heading H4K In a system where the transmission quality of a switched communication path determines whether terminal equipment need be incorporated in the path, one end of the path is equipped with a signal generator that transmits a code of a similar format to that to be used in the communication while the other end is equipped with a suitable receiver. If the latter validates the code it causes the local terminal equipment to be short circuited and reverts another code which produces a similar effect at the first end. The system is particularly concerned with cutting-out the need for D/A and A/D converters when switching digital signals through a four-wire tandem exchange. The prior art is depicted in Fig. 1. Therein relays A1, A2 operate to cut-out the converters if battery U2, U1 respectively penetrates the phantom of a switched connection between the terminals LA1 and LA2 In Fig. 3, a common generator KG1 transmits a digital code word or a frequency at the upper end of the, e.g. 52 KHz, band occupied by a digital transmission so that if a switched connection between two terminals is satisfactory, a receiver KE2 can respond and in so doing enable relay A2. The latter bridges both of the converters at its end of the path and applies a holding earth (a25) to the phantom. Simultaneously a generator KG2 (which may be the same as KG1) transmits a signal over the Return path so as to similarly enable a converter-bridging relay A1. The two relays are held over the respective phantoms and both generators are disabled during the connection. In Fig. 4 (not shown) the generator KG2 is dispensed with, the holding contact a25 serving also to actuate relay A1. In Fig. 5 (not shown), the Go and Return paths each incorporate an arrangement similar to Fig. 4 but arranged such that each path is independently controlled by a separate pair of relays and generators.
