Title: Improvements in the vacuum preservation of foodstuffs
IPC: A23L2/44
Filed: 1963-05-13
Abstract: 986,178. Preserving liquid foodstuffs. E. BECKMANN, D, BECKMANN, and U. BECKMANN. May 13, 1963 [May 15, 1962], No. 18898/63. Heading A2D. A foodstuff in liquid or emulsion form is preserved by degasifying and de-aerating it in a container by the application of a vacuum of absolute pressure at least as low as 9 mm. Hg. (preferably 2 mm. Hg.), the vacuum being such that the foodstuff is cooled to a temperature no higher than 8‹C., but is not frozen, by evaporation of a portion of its water content, so that decomposition due to bacteria, enzymes and fermentation is substantially suppressed, and the foodstuff is stored in the degasified and de-aerated condition. Liquid food is drawn from tank 13, Fig. 2, into a chamber 1 held under the high vacuum created by a steam jet ejector 3 with an associated steam feeding line 4, a watercooled condenser 6 and an air pump 9 to keep the condenser under vacuum. During the vacuum treatment and cooling of the food in the chamber, air sucked in past the valve 11 induces circulation of the food, as depicted. Alternatively, the food may be stirred mechanically. If the food does not contain sufficient liquid capable of being vapourized under vacuum, water (previously filtered or sterilized by ultra-violet radiation and degasified) may be added through conduit 15 prior to or during the application of the vacuum. The food may be introduced into the chamber in the form of a spray directed on to a rotating disc or rotating vanes. In order to avoid any possibility of freezing, the food may first be heated by superheated steam or hot air in a continuous flow heater partially filled with glass balls or small stones, Fig. 5 (not shown). The treated food may be extruded from the chamber (if desired after storage therein) by pressurized inert gas or steam. Milk cream, fruit and vegetable juices, pulps and slurries, emulsions of oils and fats with water, and medicines are mentioned. Specification 821,369 is referred to.

Title: Improvements in the production of acid chlorides
Inventor: SEEFELDER MATHIAS
IPC: C07C51/60
Filed: 1959-06-03
Abstract: Carboxylic acid chlorides are prepared by reacting a compound of formula (R4)(R6)C:C (R5)COOH, where R4, R5 and R6 represents hydrogen, halogen, or aliphatic, araliphatic or aromatic radicals, or, in pairs, common members of a cycloaliphatic ring, with phosgene at temperatures below 150 DEG C and in the presence of a compound of formula R1CO.N(R2)(R3), where R1 represents hydrogen or an alkyl, cycloalkyl, aralkyl, lower alkoxy or lower dialkylamino radical, R2 and R3 represent alkyl, aralkyl, or aryl radicals, and where R1, R2 and R3 may represent, in pairs, common members of a heterocyclic ring containing the carbonamide nitrogen atom.  "Lower" means containing up to 4 carbon atoms.  When R4 is hydrogen and R5 and R6 are hydrogen, halogen, aliphatic or araliphatic radicals or common constituents of a cycloaliphatic ring, and the reaction temperature is below about 100 DEG C, the products are b -chlorocarboxylic acid chlorides ; if the resulting reaction mixture is heated to above 100 DEG C, an a ,b -unsaturated carboxylic acid chloride is obtained. When R4, R5 and R6 are aliphatic, araliphatic or aromatic radicals, or, in pairs, common constituents of a cycloaliphatic ring, and where R5 may also be hydrogen or chlorine, and where R6 may also be hydrogen when R4 is aromatic, and at a reaction temperature below 100 DEG C, the product is an a ,b -unsaturated carboxylic acid chloride. Suitable compounds of the above two general formulae are listed. Specification 401,643 is referred to.

Filed: 1963-05-14
Abstract: 1,012,856. Electric selective signalling; data storage elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 14, 1963 [May 18, 1962], No. 18961/63. Drawings to Specification. Headings G4C and G4H. [Also in Divisions H1 and H3. The invention relates to the performance of logical operations on variables represented by the presence or absence and if present the physical condition of a layer of material, especially when the layer has been deposited by the thermal dissociation of a gas. Nickel or iron carbonyl gas or silicon or germanium iodide gas is passed into a chamber and caused to dissociate and deposit (or not) nickel, iron, silicon or germanium respectively at a selected location on a substrate by the local application or removal of heat. The heat may be applied by a focused light beam, an electron beam, a laser beam, or a heat radiating or absorbing junction in the substrate. A particular deposit may be removed by producing the inverse thermal condition at the location and passing the appropriate gas into the chamber, e.g. carbon monoxide in the case of deposited nickel, thus reversing the original chemical reaction. In performing logical operations, the presence or absence of the deposit constitutes one logical variable, a second variable being provided by the energization or not of reading means for detecting the deposit, and a third variable being provided by utilizing two possible states of a physical property of the deposit if present. The deposit may be detected photo-electrically either by non-transmission of light directed at the deposition location or by the resultant rotation of the plane of polarization of plane polarized light directed at the location. Alternatively, the deposit may be detected by its magnetic effect. The two states referred to may be positive and negative saturation on the magnetic hysteresis loop of the deposit, or the corresponding sense of rotation imparted to incident plane polarized light (Faraday Effect). The deposit may be solid or liquid. The substrate may carry a square matrix of said deposition locations.

Abstract: 1499190 Television NISSAN MOTOR CO Ltd 7 May 1975 [7 May 1974] 19125/75 Heading H4F The smearing of moving images is reduced by scanning a reduced area, i.e. 1/a of the target area, of a Vidicon camera with a number of scanning lines reduced to 1/b of the standard number, but with a frame rate increased by a factor a. In this way the target potential is reduced to the 10% level in about the same number of frames but in a shorter time than when using conventional standards. Preferably a=b<SP>2</SP> so that the signal bandwidth remains standard. As an example, line frequency = 63 kHz (4ÎNTSC standard), frame frequency = 504 Hz (16 Î NTSC standard) and the area scanned is 1/16 of the target area. Fig. 1 shows apparatus for performing the method wherein line frequency is set by generator I and frame frequency by divider 7. The size of the raster scanned is determined by amplitude controls 4, 11 and its position by D.C. bias controls 3, 10.

Abstract: 834,057. Screening apparatus. SMIDTH & CO. A. S.. F. L. May 16, 1958 [June 18, 1957], No. 19192/57. Class 117 Material is separated into fine and coarse fractions by being delivered at high speed more or less tangentially on to a stationary concave screening surface 1 within a casing 2, and the finer particles pass through the screen to an outlet 7 and the coarse fraction passes to an outlet 4; to prevent clogging of the screen jets of fluid, e.g. air, are directed against the screening surface from a nozzle structure 8, and are moved along it such that each screen opening is alternately, and in rapid succession, traversed in one direction by the fluid and left free for the passage of fine particles in the opposite direction. The material may be an aqueous suspension supplied through a pipe 3 and nozzles 3a at high pressure. The nozzle structure 8, Fig. 2, comprises a number of perforated pipes 12 within a closed frame of piping fed with fluid from a pipe 22 and hose 23. The structure is pivoted about a shaft A by arms 14, and is reciprocated about that shaft by an eccentric drive 17. In the embodiment of Figs. 4 and 6 the screen is cylindrical but only one quarter of it is used at a time. Material is fed to one screen section through a pipe 27 and nozzles 28, and the coarse fraction passes through a space 26 to a hopper 29 and the fine fraction passes to a hopper 31. The whole screen can be turned about its axis to bring a fresh screen section into operation when one section is worn. The nozzle structure for the emission of fluid comprises four perforated pipes 40 which rotate about the screen at high speed, and are connected to a hub 43 attached to one end of a rotary shaft 44. Fluid is fed to the pipes via a non-rotary disc 53, and bores 51 in the hub, and the arrangement is such that only that pipe which is travelling adjacent the appropriate screen section is supplied with fluid. In a modification the whole surface of a cylindrical screen is used simultaneously, and material is fed to it by a pipe, which opens tangentially into a non-perforated cylindrical axial extension of the screen, and the material travels along a substantially helical path. The fluid emitting pipes rotate about the screen and are all fed with fluid continuously. In Fig. 9 the screen 85 is of conical form, and has an extension 86 to the interior of which material is fed tangentially by a pipe 102. Fluid pipes 94 are attached to, and fed with fluid from, a rotary hub 97; coarse material passes to the hopper 90 and the fines to an outlet 93.

Title: A method of pressing oil-seeds by means of screw presses
IPC: H02P29/00
Filed: 1955-07-06
Abstract: In the extraction of oil from seeds by means of screw presses, the rotary speed of the screw is continuously controlled during the pressing operation so as to maintain a constant pressure of the press corresponding to the kind and quality of the treated seed.  The pressure produced in a press is dependent on the weight per litre of the pressed seed and its oil content so that, with a constant number of revolutions of the press, the required pressure cannot always be obtained when pressing materials differing in the above respects. The continuous control of the rotary speed is derived from a constant torque corresponding to a constant pressure of the press.  An electrical control system for effecting the method is described (see Group XXXV).

Abstract: 531,623. Wireless receiving circuits. R. M. ELECTRIC, Ltd., and BRADBURY, G. H. July 6, 1939, No. 19714. [Class 40(v)] In radio receivers of the kind, which may be operated with " straight " or superheterodyne circuits, separate circuits for the signal and heterodyne frequencies are provided to the anode of the frequency changer valve and switching means for changing from one to the other and for rendering inoperative the local oscillator when the signal frequency circuit is in use. The output valve is provided with negative feed back to compensate for loss of high and low frequencies in the more selective superheterodyne arrangement. In the superheterodyne circuit a triode-hexode valve VI acts in conjunction with signal frequency and oscillator circuits S, O as a frequency changer/oscillator, the output from which is taken through the tuned primary and secondary PI, S1 of an intermediary frequency transformer to one of the anodes of a double diode second detector valve V2. To change the circuit the contacts of a double-pole change-over switch 1 are moved so as to connect the anode of the hexode portion of the valve V1 to a radio frequency choke C and to disconnect the anode of the oscillator section from the H.T. supply, the signal then passing through a condenser 2 and choke Cl to the other anode of the valve V2. The low frequency component obtained across the load impedance R common to both the anodes of the valve V2 is fed through condenser 3, potentiometer 4 and the usual resistance capacity coupling 5, 6 to the output valve V3 and transformer T. A negative feed back circuit is provided between the anode and grid of the valve V3 comprising resistances 7, 8 connected by a condenser 9 the junction of the resistance 7 and condenser 9 being connected to earth through a condenser 10. The amount of negative feed back may be controlled by connecting a potentiometer 11 and condensers 12, 13 in the network the movable arm of the potentiometer 11 being connected to earth.
