Title: Improvements relating to radiation gauges such as beta gauges
Inventor: GILMAN SAMUEL
IPC: A24C5/34
Filed: 1953-04-07
Abstract: 745,153. Radiation density gauge. INDUSTRIAL MACHINERY CO., Ltd. Feb. 26, 1954 [April 7, 1953], No. 9351/53. Class 40 (3). [Also in Group XXX] Long, narrow articles such as cigarettes are fed to a radiation gauge in a direction transverse to their length so as to pass through the measuring station with their axes parallel to the direction of radiation. As shown, individual cigarettes from a continuous rod are fed to semicircular recesses in a drum 18 which they enter at the position 32. The drum is intermittently rotated by a gear wheel 20 having teeth 21 engaged by a rotating pin 22. Pin 22 is carried on a rotating cam 25 which rocks a lever 27 against the action of a spring 29. The lever 27 has a head 32 with a semi-circular recess and the operation is such that the head is lifted while the drum rotates to position a cigarette at the point 31 when the head is lowered and a radiation beam (e.g. Beta rays) passes axially through the cigarette to a detector (ionization chamber, Geiger tube or scintillation counter) at the far end. After a fixed period determined by the rotational speed of cam 34 head 30 is lifted, drum 18 is stepped on and the cigarette, if defective, is removed from the drum at 34. If not it is stripped from the drum at position 35. In further arrangements the grooves on the outside of one drum co-operate with internal grooves on a second drum whose axis is displaced from that of the first while in a still further arrangement the cigarettes are held in recesses in co-operating belts. The intermittent feed may be produced by a Geneva stop mechanism or the feed may be continuous when the gauge traverses for a period with the cigarette under test and is then quickly returned to its starting point.

Title: Improvements in or relating to liquid level operated electrical control gear
IPC: G05D9/12
Filed: 1944-05-16
Abstract: 595,750. Indicating liquid-levels. HOLDEN, W. B., and CHANCELLOR, W. H. May 16, 1944, No. 9401. [Class 123 (i)] [Also in Group XXXV] An electric system for controlling or indicating liquid-level, comprises a receptacle having an electrode energised by a transformer so that current flows through the liquid and a rectifier to energise a D.C, operating relay. The control or indicating circuit 2, 3 comprises a direct current relay 5 energised through a rectifier 8 from a mains energised transformer 1, the secondary circuit being completed through any number of electrodes 12, 13 in a receptacle 14 containing distilled water or other conducting liquid, the level of which is variable to control the circuit. Two-way switches 4, 9 both shown in the de-energised position, are operated by the relay 5. When the level of the liquid rises to the electrode 12, current passes through the rectifier, through contact 10 and operates the relay to engage, before leaving contact 10, a contact 11 connected to the electrode 13 which, being deeper in the liquid causes the relay to hold in firmly. The circuit 2, 3, may control a pump to reduce the liquid level in the container and when this falls below the electrode 13 the relay de-energises the circuit. A manually operated two-way switch 7 is connected so that, on reversal, the liquid level may be made to rise when the circuit is energised.

Title: Improvements in apparatus for regulating the supply of fuel to furnaces
IPC: F23H11/20
Filed: 1930-03-25
Abstract: 349,207. Thermostats. ROUCKA, E., Blansko, Czecho-Slovakia. March 25, 1930, No. 9495. Convention date, March 30, 1929. [Class 64 (ii).] In apparatus of the kind in which the fuel supply to a furnace is controlled by a heat sensitive device influenced by the temperature of the fuel bed at the rear of the grate through a heat transmitting medium which acts upon the heat sensitive device, air is employed as the heat transmitting medium and passes through a conduit located over the rear end of the grate. As shown in the Figure, air from the atmosphere passes through a conduit 14 having internal ribs 18 and located over the rear of the travelling grate 2 to a conduit 42 leading to the furnace flue 38 and containing a heat sensitive strip 22, which, when the temperature falls at the rear of the grate, closes an electric contact at 26 and allows a current to pass from the mains 32 to an electromagnet 28 adapted to operate a switch 30 to start the motor 12 for driving the grate. When a fresh portion of fuel is brought under the conduit 14, the temperature of the air passing therethrough is raised and the strip 22 is affected so as to stop the motor. To prevent over regulation an adjustable heating resistance 34 through which current passes when the motor is started is arranged beneath the heat sensitive device 22. A damper 44 is arranged in the conduit 42 and is adapted to be opened and closed simultaneously with the opening and closing of the flue damper 40. To ensure that air passes to the conduit 42 at low loads a damper 46 is provided in a branch flue and is adapted to open when the valves 40, 44 are closed or partly closed. Air from the furnace mixed with furnace gases may be passed through the conduit 14 or air may be forced through the conduit by a fan.

Patent GB-495188-A (GB)
Title: Electric impulse transmitter
IPC: G08C19/20
Filed: 1937-04-05
Abstract: 495,188. Electric control systems. BLECHSCHMIDT, H., and MUNNICH, R. April 5, 1937, No. 9570. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 7, 1937.] [Class 40 (i)] An impulse transmitter comprises two units having a common return line and common supply, each controlling different distant apparatus and comprising a manually rotatable driving shaft imparting movement through a lag-producing device to a cam-shaft with a speed governor and an interrupter, the impulses passing to a switch arm co-operating with the driving shaft in order that one of two lines may be energized according to the direction of rotation of the driving shaft. The main shaft 2, rotated by knob 1, carries a toothed wheel 4 engaged by a switch arm 21 which is slotted at 20 and urged forward by a spring 21c. Upon the shaft 2 being rotated, the insulating block 22 engages the spring 18a and causes the contacts 57 to close. A loose pulley 6, carried by shaft 2 and coupled to it by a spring 7, engages a pulley 9 on shaft 8 which is speedcontrolled by a centrifugal governor 11. The cam 12 engages projections on springs 16a, 16b so that the contacts separate at every half revolution of the shaft 8, a roller 15 on arm 140 also engaging in notches 14 on a disc 13. The current from the battery 41 passes to the interrupter consisting of springs 16a, 16b, cam 12 and contacts 17 to springs 18, 18a and across either contact 56, 57 to a receiver arranged to vary the tuning of a wireless set. Upon reversal of rotation of shaft 2, the arm 21 moves over to a position where further rotation causes the contacts 56 to close. A pointer S moving over a scale indicates the corresponding position of the receiver, the cord 53 passing around a loose pulley 35 which is rotated by a pin 36 projecting from the shaft 2 in order that the movement of the arm 21 from one position to the other will not be indicated, the loose pulley 6 and spring 7 serving a similar purpose for the shaft 8. In order to ensure that the shaft 2 is not rotated when the transmitters and receivers are not connected, a stop pin 25 is urged by a spring to engage a toothed wheel and is retracted by the electromagnet 23 when the receiver indicating the wave-range in use is connected, one of the lamps 32a, 32b, 32c being lighted. For varying other controls, e.g. tone, wave-range and band-width, a second transmitter B is provided, exactly similar to the first but without the electromagnetic locking means. The output passes through the switch to an appropriate receiver, the switch comprising spring-returned rods 28 having projections 30 which engage under the detent bar 29 when depressed.

Title: Improvements relating to the treatment of boiler feed water
Inventor: BLIGHT FRANK CHARLES
IPC: B01J47/04
Filed: 1955-04-01
Abstract: 768,310. Purifying water by ion-exchange. PERMUTIT CO., Ltd. April 1, 1955, No. 9581/55. Addition to 699,666. Class 46. The water from the anion-exchange material (or mixture of cation- and anion-exchange materials), 17, of the parent Specification is delivered, at a rate greater than is required for use as make-up water in the plant, to a control valve 18 which allows most but not all of this water to enter a condenser 25. The excess water flows up a pipe 26 to the surge tank 27, and in consequence of the resulting continuous flow back to the sump 15 along the overflow pipe 23 the surge tank need not be baffled or otherwise constructed to keep the water out of contact with the atmosphere. The water pumped at 28 from the condenser 25 is still in excess of that required by the boilers ; the amount actually required passes through a deaerator 24 while the excess flows up a pipe 29 to the tank 27. Specifications 553,233 and 694,778 [Group IV(a)], are referred to.

Title: Improvements in or relating to continuous ring spinning machines
IPC: D01H1/30
Filed: 1923-04-09
Abstract: 195,983. Burkard, P. April 8, 1922, [Convention date]. Spindle-driving apparatus; driving-arrangements; building-motions.-The speed of the spindles of ring spinning-machines is varied during the building of the cop so as to ensure a constant speed of a traveller and a uniform twist in the yarn. The tin-roller shaft 4 is driven from the main shaft 3 through differential gearing 5 - - 8 controlled by cone-mechanism 16, 17 driven from the roller shaft. The cone 17 is connected to the cage 9, which carries the planet wheels of the differential gear, and is driven frictionally from the cone 16 by an interposed belt, which is shifted by a lever 27 in accordance with the building of the cop. A cam 46, which is slowly rotated by a quadrant 50 and ratchet gear 53, is arranged so as initially to maintain the lever 27 at one end of the cones and to allow an oscillation thereof, the amplitude of which gradually increases during the formation of the cop bottom and thereafter remains constant. The lever 27 is oscillated from the building-motion lever 28 by a pin 43, which engages a slot in an arm depending therefrom. The quadrant 50 is operated by a finger 49 fast on the shaft of a pulley 33 attached to the chain 31 of the building-motion ratchet-mechanism. A horizontal bar 35 connected to the lifting-pokers is connected by a chain 34 to the pulley 33. To compensate for the irregularities due to the rise and fall of the ring rail, the cone 16 is driven during the fall of the rail by gearing 63, 64 and a ratchet 69, which overruns during the rise of the rail, when the cone is driven at a higher speed by gearing 61, 62 and a clutch 65 operated from the ring rail. Bv using a differential gear which operates by reducing the speed, an electromotor may be coupled direct to the driving-shaft or a small driving-pulley 21, Fig. 3, may be driven from a pulley 22 on a shaft 23 arranged in the head-stock, the pulleys 21, 22 being changed as desired to vary the speed. The pulleys 21, 22 may be cone pulleys so that the frame may be driven at an adjustable speed, or at a speed which may be varied in the known manner during the formation of the cop to reduce the variation in tension when winding on different diameters, the variation being effected by mechanism which acts on the tension pulley 24.

Title: Process for the preparation of sucrose esters
IPC: C11C3/04
Filed: 1959-03-20
Abstract: Sucrose mono- or di-esters of fatty acids containing 6 to 30 carbon atoms are prepared by interesterifying sucrose with an alkyl or glyceryl ester of the acid, wherein the alkyl group contains 1-3 carbon atoms, in the presence of dimethyl formamide as reaction medium and a basic catalyst, thereafter adding an aliphatic carboxylic acid containing 2-4 carbon atoms to the reacted mixture to adjust its pH to at least about 5 but less than 7, the addition being preceded, if desired, by a filtration, then, in the case of a sucrose diester being the final product or optionally when a sucrose mono-ester is being prepared, extracting from the mixture unchanged fatty acid ester reactant and any free fatty acid by means of a solvent for the unchanged ester and fatty acid which is immiscible with dimethylformamide and a non-solvent for the sucrose ester, and thereafter in either case evaporating the bulk of the solvent in vacuo from the interesterification mixture, dissolving the ester residue in a mixture of two mutually miscible solvents, one of which is an aliphatic alcohol which is partially soluble in water and is a solvent for the sucrose ester and the other is a water-insoluble solvent incapable of dissolving dimethyl formamide, extracting sucrose from the resulting solvent mixture by washing with water and aqueous saline solution and evaporating the solvent mixture containing purified sucrose ester to dryness, after, if desired, decolorising with charcoal and a decolorising earth and filtering. Suitable solvents for the purification are petroleum ether for removal of unchanged ester and free fatty acid and a mixture of butanol and cyclohexane or petroleum ether for the subsequent removal of sucrose.  Examples describe the preparation of (1) sucrose di-palmitate from the methyl ester and (2) sucrose mono-stearate from methyl stearate.  Specification 824,654 is referred to.

Title: Entrainment or feed roller for up-twister spindle twisting frames, particularly double-twisting frames
IPC: B65H71/00
Filed: 1965-03-09
Abstract: In a two-for-one twisting frame where the twisted yarn is taken up on a bobbin via a traversing guide, the tendency of the yarn tension to change as the guide moves is offset by providing, in advance of the guide, a driven roller of paraboloid or hyperboloid form, over which the yarn travels on varying diameters as the guide moves.  The roller may be asymmetrical where tapered packages are to be wound; it may have annular or helical grooves; it may be hollow and comprise a thin outer shell between end-flanges; or as in Fig. 6 (not shown) it may comprise a filling of resilient material comprising members 44, 45 hinged together and of which one is secured to the spindle, which members when secured together by eccentric flanges 49 secure in place the inturned ends of a thin shell.  A member, with means for supplying it with treating-liquid or pressurizing-fluid, and having a surface of complementary form with, and in contact with, the roller may be placed above it, Figs. 7 and 9 not shown.  A second roller in driving contact with, and of similar shape to, the feed-roller, may precede it, to deflect the yarn and tension it to an extent indicated by a scale.  This roller may have a conical extension with helical grooves and cooperating with a cylindrical extension of the first roller to facilitate stringing-up.
