Title: Improvements in processes for the manufacture of glucose of increased purity
IPC: C13K1/08
Filed: 1951-06-28
Abstract: Starchy materials are converted into glucose in an aqueous acidic medium under steam pressure and the converted liquor is neutralized, filtered, decolourized, refined and concentrated. Part of the concentrated liquor produced is crystallized dynamically i.e. in motion, and the resulting primary massecuite is separated into glucose crystals and a first green liquor which is percolated through base-removing substances regenerated with regenerants which import hydrogen ions.  Some or the whole of the percolate thus obtained is mixed with fresh unconverted starchy materials at the start of the process.  The remaining concentrated liquor is crystallized statically, i.e. without movement, to yield hard slab sugar blocks in which uncrystallizable liquor is confined in a mass of glucose crystals.  Part of the aforementioned percolate may be percolated through acid-removing substances, filtered, refined, evaporated and crystallized statically into secondary hard slab sugar blocks. Alternatively, part of the percolate from the base-removing operation is reconverted and then percolated through acidremoving substances. Some of the percolate thus obtained is mixed with first converted liquor.  The remaineder is filtered, refined and concentrated.  Part of the concentrated liquor thus produced is crystallized statically into secondary hard sugar blocks and the remainder is crystallized dynamically to form a secondary massecuite which is separated into secondary glucose crystals and a second green liquor.  Some of this liquor is mixed with first green liquor before the base-removing operation.  The remainder is crystallized statically into tertiary slab sugar blocks. Specification 554,826 is referred to.

Title: Improvements in centrifugal separators
IPC: B04B1/12
Filed: 1931-05-26
Abstract: 373,412. Centrifugal machines. AKTIEBOLAGET SEPARATOR-NOBEL, 8, Fleminggatan, Stockholm. May 26, 1931, No. 15401. Convention date, June 11, 1930. [Class 23.] A centrifugal separator is arranged so that three substances, preferably liquids, can be separated and discharged continuously. The bowl shown in Fig. 1 is used during refining processes to separate oil, sulphuric acid, and goudrons. The mixture is fed in by the central inlet 1 and the oil is discharged from the outlet 5. Outlets 6, which may be capillary nozzles, permit the sulphuric acid to escape, but the goudrons, which have a higher viscosity, are compelled to move through the channels 7 to a regulatable outlet 8 arranged outside the outlet for the oil. The outlets 6 can be arranged in a zone to permit the intermediate liquid to escape instead of the heaviest liquid. The capillary nozzle may be formed by a channel 10, Fig. 2, with a conical valve seat 11 at its inner end. A valve body 12 with a conical head 13 rests in this, and when the bowl is rotated the body is thrown outwards and a capillary conical channel is formed between the cone 13 and its seat. In the modification shown in Fig. 3 the head 15 presses together a number of thin metal rings 17 between which the capillary channels are formed.

Title: Improvements in and relating to the digesting of fibrous or cellular material
IPC: D21C1/00
Filed: 1935-05-27
Abstract: Pulp is obtained from bagasse, corn stalks, cotton linters, or stalks, flax stalks or waste, grasses, canes, bamboo, straw, jute, hemp, sisal, manilla, spruce, pine, chestnut, hemlock, fir, oak, poplar, &c., by compacting to remove substantially all air, as by forcing liquid, gas or powder through it, and feeding it thus compacted to the digestion zone, formation of sulphuric acid from sulphurous acid being thus prevented.  The material fed to a hopper 1, Fig. 2, is soaked by water which may contain lime, Turkey red oil &c. supplied at 3, is compressed by a reciprocating piston 6 into a converging inlet 7 to form a moving plug which withstands the pressure of digestion, air, excess solution &c., passing through perforations 8.  Ammonia, nitrogen, or calcium oxide as powder, or in solution &c. may be pumped into a jacket 9 surrounding the perforated inlet 7.  Sulphite or other liquor supplied at 20 is passed by a pump 25 through two heat-exchangers 21, 26, valves 29, 30 and impregnates the fibrous material passing along a perforated container 32 which is rotated at a <PICT:0457524/IV/1> <PICT:0457524/IV/2> speed governed according to the rate of feed &c., and by a float 40 in a dome 39 which is similar to that described in Specification 428,120, [Group VIII], and enables sulphur dioxide, turpentine, furfural &c., to be recovered.  The ratio of digesting liquor to fibrous material should be less than 5 : 1, e.g. 2\ba1/2\be to 1, and the digester contents are heated by coils 35 supplied with steam &c., at 36.  The digested material is withdrawn by a rotating valve 45, Fig. 3, adjacent parts being of chemically resistant metals, blown from the pockets of the valve 45 by expansion of steam &c., and compressed by a loosely fitting piston 55, the expressed liquor being collected at 59 &c., and may be pumped through a filter 64 and heat-exchanger 69 to plant for recovery of carbohydrate materials, alkaline bases, tannins, waxes, &c.  Alternatively the converging part 58 of the discharge pipe 54 may be perforated and jacketed to allow removal of expressed liquor.  The door 53 at the end of the pipe 54 is closed initially until a plug of pulp has been formed.

Title: Improvements in and relating to toy guns
IPC: F41B7/00
Filed: 1919-06-20
Abstract: 143,075. Black, R. C. June 20, 1919. Projectors.-A toy gun is mounted in a wheeled casing representing a tank, and is adapted to shoot a number of balls in succession by the rotation of a handle. The balls are stored in a magazine 5 placed below the barrel 4 of the gun, and are lifted one at a time to the breech of the gun by a vertically-moving elevator 9 which is connected to an arm 13 secured to a shaft 14. This shaft is rocked by the driving-shaft 17 which has a projection 19 engaging the upper end of a spring 15. Thus, as the shaft 17 is rotated, the elevator raises a ball to the rear of the tube 4, and the spring 15 is drawn back and released, so that it strikes the ball and propels it from the gun.

Title: Cathode ray tube, more particularly for television purposes
IPC: H01Q19/22
Filed: 1934-05-28
Abstract: 440,560. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. May 28, 1934, No. 15780. Convention date, May 27, 1933. [Class 39 (i)] Magnetic fields are produced in Braun tubes with picture screens for television &c. by means of pole-shoes inside the evacuated envelope of the tube and a field generator outside the envelope, both extending as close as possible to the envelope to reduce the gap between them and the shoes extending as close as possible to the ray. The magnetic field deflects or concentrates the ray and the pole-shoes may act simultaneously electrostatically to control the intensity of the ray or to concentrate or deflect it. An opposed pair of pole-shoes may deflect the ray horizontally and vertically at the same point along the tube, one deflection being electromagnetic and one electrostatic. The pole-shoes may be layers 3, 4, Fig. 4, of permalloy or steel on an apertured copper diaphragm 16. In a modification, semicircular pole-shoes are separated at each side of a central hole by a copper strip to form an apertured disc anode. For electrostatic concentration of the ray, one side of the pole-shoes is concave. Before reaching the usual deflecting plates, the ray may be given a preliminary constant deflection by passing between two polepieces co-operating with rotatable half-ring magnets 1, Fig. 3, the field of which is varied by adjusting a magnetic shunt consisting of loops 13, 14 joined by a strip 15. The ray from a cathode 18, Fig. 7, is concentrated by the magnetic field between pole-shoes 19, 20 co-operating with a coil 31, is modulated by control potentials applied to the shoes 19, is successively deflected whilst moving at slow and preferably constant speed by the fields of pole-shoes 24, 25 and is finally accelerated by an anode 26. Screens 21, 22 are continued outside the tube and provided with a constant bias. The tube is highly evacuated or gas-filled, preferably at a pressure of 10<-4>-10<-5> mm. To compensate for variations in the anode voltage, the currents through the coils producing the magnetic fields increase with this voltage.

Title: Improvements in power plants including at least one free piston auto-gas generator
Filed: 1950-06-23
Abstract: 685,943. Gas turbine plant. SOC. D'ETUDES ET DE PARTICIPATIONS; EAU, GAZ, ELECTRICITE, ENERGIE SOC. ANON. June 23, 1950 [July 16, 1949], No. 15785/50. Class 110(iii) [Also in Group XXVII] A gas turbine plant comprising a free piston gas generator feeding a gas turbine which is controlled, when the turbine power drops below a certain level, by means which allow some of the power gases before the turbine to be led to a second turbine which is coupled to the first turbine in such a manner that when both turbines are supplied with power gases they act with opposing torques on a power shaft. The gas turbine shown comprises a free-piston gas generator feeding a gas turbine 23 through a conduit 21 and a reservoir 20. The gas generator comprises a power cylinder 1 having a piston 2 connected to a compressor, piston 5. The air compressed on the upper side of the piston 5 is used to supercharge the power cylinder 1 and that on the lower side is used to return the piston to the upper position. The output of a fuel pump 11, driven from the piston 5 by a rod 12, is controlled by a rack 15 operated by a hand-wheel 35. A contact member 17, connected to the rack 15 and a piston 18 movable in a cylinder 19 in response to changes in the charging pressure which is related to the pressure of the power gasses leaving the ports 4, co-operates with abutment surfaces 16 of a stop. A resilient device 37 allows the surfaces 16 to operate. A conduit 30 leads from the conduit 21 to a second reverse drive turbine 25 mounted on the shaft of the turbine 23. The arrangement is such that the power output of the turbine 23 is reduced by reducing the output of the gas generator. Since there is a limit below which the output of the gas generator cannot be reduced due to the necessity of clearing the inlet and exhaust ports 3, 4, on the outward movement of the piston 1, further reduction of the power output is obtained by opening the valve 31 and bypassing some of the gases into the turbine 25. The valve 31 may be operated until the conduit 29 is shut off and all of the gases flow to the turbine 25 when the direction of rotation of the propeller 27 will be reversed. In a mid-position of the valve 31 the torques of the turbines 23, 25 will be equal and the propeller 27 will then be stationary. In a modification, the valve 31 and the fuel control 15 are operated from a common handwheel through cams.

Title: Improvements in power indexed tool holding turret heads for boring mills and like machine tools
Inventor: FOSTER THEODORE
IPC: B23Q16/10
Filed: 1956-05-23
Abstract: 815,799. Machine-tool details. AMERICAN STEEL FOUNDRIES. May 23, 1956, No. 15940/56. Class 83 (3). A power-indexed turret tool head for boring- mills and like machine tools comprises poweroperated cam means for moving the turret along its pivotal axis to disengage locking means prior to the indexing movement. Initiation of a turret-indexing operation from the locked-and-clamped position of the turret 8 shown in Fig. 2 is effected by closing a control switch, thus starting a motor drive to a bevel wheel 20 on the support member 6. The drive passes through bevel wheel 22 to a timing wheel 26 and a sun-gear 32, which is in the form of a sleeve and carries gear teeth 38 at its opposite end, to drive planet wheels 44 on a spider 40. The latter is also in the form of a sleeve and surrounds a supporting spindle 76 for the turret. The forward end of this sleeve has a splined connection with a cam ring 54, which co-operates with another cam ring 58, Fig. 5, to allow the turret to be raised from its seating by springs 108, Fig. 2. The first movement of the gearing causes rotation of the spider 40 and axial release of the turret 8 from its seating. The turret is locked against rotation during this movement by a spring-pressed plunger 90, Figs. 2 and 3, which engages a notched ring 80 secured to the back of the turret with a gear ring 78. A cam groove 86 in the side of the timing wheel 26 engages a pin 88 secured to the back of plunger 90 to lift it from ring 80. On such movement a latch 118 on the lowest part of the plunger is brought up into engagement with a further internally notched ring 82 secured to the inside of the spider 40. The latter is thus held against rotation when the turret is released, and the planet wheels then rotate the turret through the ring gear 74 to the next index station. A limit switch 104 is operated at the completion of indexing and re-clamping by a projection 100 on wheel 26 engaging a plunger 102, Fig. 2. Additional locating keys 72 are provided around the interior seating of the turret to obtain accurate positioning.
