Abstract: 1,158,103. Emulsions, frozen desserts, ice cream, mousses. UNILEVER Ltd. 17 March, 1967 [30 March, 1966], No. 14121/66. Heading A2B. An emulsion, which may be used for preparing a dessert by freezing and whipping, is prepared by homogenising a mixture of fatty acid triglyceride oil, water, and major and minor protein, as defined, the proportion by weight of minor protein to major protein being at least 0.25, to form an oil-in-water emulsion having an interface at which both major and minor protein are adsorbed, and thereafter increasing the proportion of major protein to minor protein by dispersing further major protein added in a concentration of at least 3% by weight. By major and minor protein is meant that in a system containing several proteins, the protein of the highest collapse pressure that is capable of competing with all or part of the remaining protein for position at the air- or oil-water interface, and is present in significant quantity, is the major protein, and the other proteins of lower collapse pressure constitute the minor protein. In examples, casein comprises the major protein and gelatin, alpha-lactalbumin, and #-lactoglobulin the minor proteins. The oil may be milk fat or butter. The mixture to be homogenised may comprise the oil, water, skim milk powder, and gelatin or whey powder. As novel products there are obtained ice creams of at least 90% overrun having a sectilometer hardness of at least 80, a shape factor of at least 60%, and a coolness of less than 19, and mousses of at least 70% overrun containing less than 1.2 wt. per cent. gelatin and having a sectilometer hardness of less than 90.

Title: Alarm systems
IPC: G08B25/04
Filed: 1970-03-24
Abstract: 1310169 Smote detectors; SIEMENS A G 24 March 1970 [25 March 1969] 14154/701 Heading G1N [Also in Division G4] A fire alarm system comprises a number of smoke detectors connected to a central station, each detector being adapted to produce a different frequency a. c. signal. Each smoke detector K2, in the form of an ionisation cell with two radio-active chambers, is connected in series with a reference detector K1, the detector K1 being sealed and the detector K2 communicating with the air. The presence of smoke causes the conductivity of the detector K2 to be reduced so that the potential at a point 3 changes, terminals 1, 2 being connected to a source of potential in the control station. A field effect transistor T1 is therefore triggered and an audio frequency signal, having a frequency dependent on the values of a capacitor C and a winding L1 of a transformer L1, L2, is fed to the central station. Filter circuits at the central station channel the signal to a respective indicator device to identify the position of the detector that has sensed smoke. In a modification the circuit is maintained in oscillation when the detector ceases to sense smoke. The detector circuits may be triggered for test purposes by increasing the voltage applied to the terminals 1, 2. A lamp and further transistors may be included in each detector circuit so that the lamp is energized when the detector senses smoke, thereby indentifying the operated detector.

Patent GB-486908-A (GB)
Title: Improvements in the manufacture of ferrous alloys
IPC: C21C7/00
Filed: 1937-05-24
Abstract: In producing ferrous alloys by the metallothermic reduction of magnetic iron oxide, the materials constituting the charge, including the alloying metals and oxydizing agents, are dried by heating to at least 100 DEG  C. before introduction into the crucible in which the reaction is effected, thereby eliminating blisters in the steel produced.  The magnetic oxide of iron may be magnetite, roasted iron scales, or a mixture of these.  The oxydizing agents may consist of salts of the alkaline earth metals, particularly barium dioxide or barium nitrate, or of mixtures such as potassium nitrate, barium nitrate, and barium oxide.  In an example, a mixture is made of magnetite, roasted iron scales, aluminium, potassium nitrate, barium nitrate, and barium dioxide, all ground and dried previous to mixing. A second mixture is formed of dried potassium nitrate, ferro - chromium, and nickel.  The mixtures are, if necessary, passed through a grinder-mixer, and both are maintained in a dry atmosphere at at least 100 DEG  C.  The crucible, also heated to at least 100 DEG  C., is charged with a layer of the first mixture, then with a layer formed of an intimate admixture of the first and second mixtures, and finally a layer of the first mixture.  Ordinary carbon steel or pig iron scrap is distributed partly on top of the second layer and partly in the top layer. The reaction is started in known manner by an ignition cartridge in the charge, and containing for example aluminium powder, barium dioxide, and magnesium powder.  To refine the steel, the ladle into which it is poured may contain a charge of manganese and aluminium; alternatively, above the first layer in the crucible may be placed three superposed layers consisting respectively of manganese, a portion of the first mixture, and another of manganese.  In a second example, the charge in the crucible is formed by a layer of a mixture of magnetite, aluminium, potassium nitrate, titanium oxide, barium nitrate, and barium dioxide, a second layer of manganese, a third of a mixture of ferro-molybdenum and silicon, a fourth layer of the first mixture with carbon steel scrap and fragments of pig iron distributed in it, and a top layer of the first mixture alone.  Drying is carried out as in the first example.

IPC: G01T1/115
Filed: 1965-04-05
Abstract: 1,143,941. Photo-electric dosimetry. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 29, 1966 [April 5, 1965], No.14451/65. Heading G1A. The dose received by a quantity of thermoluminescent material during irradiation, is determined by gradually heating the material and integrating the light output of the material received by a photo-electric detector within a particular temperature range. The temperature range chosen is that at which the light output is truly representative of the dose received by the material during irradiation, the light output above this range resulting from spurious effects due to mechanical movements of the powder crystals, and the output below this range represents stored energy which, though due to the irradiation dose, has partially decayed, and would thus give an inaccurate value of the dose received by the material. The powder is heated on a resistance tray 3, the temperature of which is measured by a thermocouple 10, the output of which is amplified at 9 and recorded on a graph recorder. The light emitted is sensed by a photo-multiplier 2 whose D. C. output is converted into pulses formed at a rate directly proportional to the input current by unit 6 and the pulse rate measured by ratemeter 8 whose output is also recorded on the graph recorder 11, so that a continuous record of light intensity against temperature is obtained, Fig. 2 (not shown). The pulse unit 6 is also connected to a scaler 7 which integrates the light output of the material. The scaler is arranged to be switched into circuit at a certain temperature and switched out a second higher temperature, the limits of the chosen temperature range. This is arranged by the thermocouple amplifier output being fed to two discriminators 12, 13 controlling relays RLA and RLB.

Abstract: 945,800. Dynamo-electric machines; mercury switches; fluid actuation of switches. SPEIDEL INDUSTRIAL DIVISION Inc. April 26, 1960 [May 26, 1959], No. 14550/60. Headings H2A and H2B. [Also in Division G1] In a gyroscopic device sensitive to angular movement about a sensing axis (see Division G1) the rotor member comprises a mercury annulus which is caused to rotate by operation of eddy currents electromagnetically produced. The unit, Fig. 1, comprises inner and outer cylindrical stacks of laminations, 2 and 3, of magnetic material with conventional motor stator polyphase A.C. windings, shown at 4 and 5, which generate polyphase magnetic flux which traverses the annular gap 6 in radial directions. The mercury 19 in the gap is caused to rotate about the spin axis 20 by the eddy currents produced. In an alternative embodiment, Fig. 5, there is provided an E-shaped electromagnetic core having a recessed winding 62. Spin motive power is achieved through interaction of the radial magnetic flux and currents produced in the liquid from sources 68. In one embodiment (Fig. 3) the differences in liquid pressure produced by the angular displacement are transmitted to the compartments 31, 32 of a mercury-filled indicating switch, thereby moving a diaphragm 33 and an insulating element 34 attached to it against the action of an adjustable spring 37, whereby at a certain value of pressure difference contact is made through the mercury between two terminals 35, 43. Element 34 has the same density as the liquid 19 it displaces, whereby it is not sensitive to extraneous acceleration forces. It is shaped to accommodate and insulate contact 35 entirely in a depression 39 in conditions of zero or clockwise differential pressures. Another oppositely constructed switch may be used to detect clockwise pressure differences.

Title: Improved method and apparatus for purifying air or gases
IPC: B03C3/16
Filed: 1933-05-20
Abstract: <PICT:0421811/III/1> In the removal of suspended particles from gases by electrical precipitation, the gases are passed through a casing and through or in contact with an insulated electrode or electrodes maintained at high potential contained therein and are then brought into intimate admixture with a mist of water or liquid that has been electrically charged and is insulated from the casing.  The electrodes and the liquid mist may be oppositely charged, whereby the particles and the liquid are attracted and the deposition is effected by gravity or the polarity may be the same and the mixture of particles and liquid are deposited on the casing or on additional surfaces of metal or ceramic material disposed in the path of the gases.  These surfaces may be perforated screens across the casing or may be arranged as baffles in the path of the gas.  The liquid may be used in such a proportion and at such a temperature as to lower the dew point of the gas with respect to any constituent.  In the arrangement shown, the gas is passed through a positively charged electrode d insulated from the casing a and then into contact with a negatively charged liquid mist from the nozzle e, the supply pipe f also being insulated from the casing.  The water or other liquid may be supplied from a tank insulated from earth which may be filled by means of an insulated bucket conveyer or by means of a spray sufficiently fine to ensure that the sprayed liquid is nonconductive. The deposited material may be withdrawn through the conical valve g. The liquid may be delivered into the casing in the form of a curtain from supply pipes disposed across the casing, or an inlet pipe may be concentrically mounted in insulating sleeves within an upright cylindrical casing and nozzles or perforations may be provided in the length and periphery of the inlet pipe to spray the gases passing between it and the cylindrical casing.  In the treatment of suspensions of tar fog in the effluent gases from cracking stills, the spraying liquid may be liquid cracking stock or gas or fuel oil.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B17/30
Filed: 1958-05-08
Abstract: 887,582. Photographic roll film cameras. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE, FABRIK PHOTOGR. PRAZISIONS - APPARATE.]. May 8, 1958 [June 14, 1957], No. 14753/58. Class 98(1). In a roll film camera in which the film wind is derived from a crank which in one direction of rotation winds on the film and sets the shutter and is then returned manually to the initial rest position, the shutter release mechanism only then becoming operable, a disc secured to the crank is formed with a first notch which controls actuation of the shutter release mechanism and with a second notch which is engaged in the rest position by a member actuated by rotation of the crank to retract the film presser plate from the film for free feeding and to hold the plate in its retracted position, means operable in the retracted position of the presser plate coupling the crank to the film wind mechanism. As shown on rotating the crank 8 anticlockwise, a disc 14 fixed to the shaft 28 of the crank moves anticlockwise a lever 17 which through a slide 21 moves the presser plate 6 away from the exposure gate 4. Continued movement of the crank causes pins 36 on a disc 35 fixed to the shaft to move (clockwise as shown in Fig. 3) clear of the tails 37 of levers 30 pivoted on a gear 29 so that the lever noses engage a ratchet wheel 34 attached to the shaft to drive the gear 29 which operates the film wind, while simultaneously the disc 14 tensions the shutter by way of link 10 and levers 11 to 13. After movement of the crank sufficient to wind on the length determined by the film metering mechanism (not shown), the crank is manually returned to its initial position, lowering the presser plate 6 on to the film but not affecting the shutter setting or film wind, and the disc is locked in this position by the lever 17. An exposure may then be effected since a lever 16 operated from the shutter trigger is then free to move into a recess 15 in the disc. Locking of the disc 14 other than in the rest position is prevented by providing two projections 24, 27 on the lever 17 which have to engage simultaneously in recesses 25, 26 in the disc and having a locking action for clockwise movement only of the disc, whereby more than one anticlockwise revolution of the crank is possible for winding leading and trailing strips on the film, the film metering mechanism being rendered inoperative meanwhile. In a modification (Fig. 2, not shown), a drum is driven by a friction clutch from the crank and has an arm moving between stops limiting the drum movement, a latch holding the drum against reverse movement. The drum carries a second arm which moves the lever 17 connected through an over-travel system to the film presser plate before the film is wound, the presser plate being held away from the film until the crank and disc 14 return to the rest position, return movement of the drum being prevented until near the end of the travel of the crank when the latch for the drum is released.
