Title: Improvements in the method of the treatment of cheese
IPC: A23C19/082
Filed: 1935-12-02
Abstract: 466,517. Cheese. BURGESS, A. F. (Kraft-Phenix Cheese Corporation) Dec. 2, 1935, No. 33351. [Class 84] Cheese more especially soft cheese containing generally 40 per cent or more of moisture, such as Limburger or Camembert, is improved in flavour, texture and keeping qualities by heating for a brief period to a temperature sufficient to render the cheese capable of flowing without imparting a deleterious flavour or odour, and then promptly subjecting it to reduced pressure so as quickly to reduce the temperature and to swell the casein. In the preferred form, the cheese, preferably comminuted and mixed with an emulsifying agent preferably 1-3 per cent by weight of anhydrous sodium phosphate added in the dry state, or whole milk powder, is fed to a hopper 10 from which it passes through a chamber 11 provided with means for withdrawing samples to a cylindrical mixer 12 surrounded by a jacket 13 into which steam or hot water is introduced. Mixing is effected by a screw 19 carried by a hollow shaft 18 having nozzles 19<1> for injecting steam into the material. The outlet valve 22 of the mixer 12 is kept closed for about two minutes until the cheese is melted and mixed with the emulsifying agent, after which it is opened and the mixture is homogenized by circulation by a pump 27 through a pipe 20 and a strainer 32 and back through pipes 34, 44, 46 to chamber 11, the direct supply of steam through pipe 18 and nozzles 19<1> being cut off. Samples taken from chamber 11 are tested at frequent intervals for their pH value, sodium bicarbonate being added through hopper 10 if too acid and phosphoric acid or disodium hydrogen phosphate if not acid enough. The temperature is maintained by jacket 13, usually between 120- 200‹ F. The circulation is continued until a thin creamy consistency is produced requiring 6-7 minutes or less. A valve 67 is then opened on which a valve 48 in pipe 44 closes automatically, and the material is fed through a mixer 50 into a vacuum pan 70. Steam is injected into the material in mixer 50 through a pipe 60 to bring the temperature to 212- 245‹ F. The pan 70 is connected through a conduit 71 to a vacuum pump maintaining a vacuum, e.g. of about 18 inches, therein. After about 3-5 mins. the maximum swelling has been imparted to the casein rendering the product smooth and velvety, and the vacuum is cut off and the contents of the pan are discharged, by opening a closure plate 78 by a lever 79, into a receptacle 80 and are preferably packed immediately while hot.

Abstract: 1359192 Flesh tone correction RCA CORPORATION 16 July 1971 [22 July 1970] 33531/71 Heading H4F Flesh tone correction of a displayed colour television image is carried out by adjusting at 25 the phase of the reference signal fed from oscillator 20 to the colour demodulators, in response to the filtered output of a phase detector 23 which produces a zero output for chrominance signals of +I phase, and respective positive and negative outputs when the phase of the chrominance signal is on either side of, and near to, +I phase. Phase detector 23 is only operative when it is receiving a gate pulse G 3  indicating that the chrominance signal is within a specified phase of + I phase, this gate pulse being produced when respective gate pulses (G 1 , G 2 , Fig. 1, not shown) representative, respectively, of the chrominance signal phase, and the specified phase about +I phase, coincide. In a further embodiment, which does not form part of the present invention (Fig. 1a, not shown), gate pulse G 3  is passed via a filter to control the amplitude of the chrominance signal fed to the Q demodulator.

Abstract: 1,064,997. Variable-speed gear. T. O. HUGHES (Detroit Bank & Trust Co.). Aug. 5, 1965, No. 33551/65. Heading F2D. A vehicle transmission includes a planetary overdrive for by-passing a torque converter and multi-speed gear. Input drive-shaft 68 drives carrier 70 of planets 71 and converter pump 78, the turbine being connected by a hollow shaft 82 to sun 90 of the four-speed and reverse gear which includes planet systems 90, 91, 92 and 86, 87, 88, brakes 98, 99, 100 and clutches 94, 95 for transmitting drive to output shaft 141. The normal drive is through the torque converter but when a road speed is reached such that a reduced engine speed is desirable, the driver releases the transmission clutches and applies brake 74 to fix the sun 69 of the overdrive whereby the output shaft is driven from ring 72. Since the sun 69 has half as many teeth as ring 72 the engine speed falls by a third for same road speed. In Fig. 3 (not shown), the transmission has a different but known multi-speed gear and in the overdrive, the sun is permanently fixed and the ring can be clutched to the output shaft when desired.

Title: Method of preparing porous material0synthetic polymer composites
IPC: B27K3/15
Filed: 1972-07-18
Abstract: 1449814 Cellulosic/polymer composite materials UNITED KINGDOM ATOMIC ENERGY AUTHORITY 16 Oct 1973 [18 July 1972] 33616/72 Heading C3P A composite material is prepared by polymerizing a polymerizable liquid comprising a monoethylenically unsaturated monomer or a mixture of such monomers in a porous natural material comprising cellulosic fibre, the polymerizable liquid being in admixture, in the porous material, with a halogen derivative of a saturated aliphatic hydrocarbon having from 22 to 30 carbon atoms. The polymerizable liquid may include a crosslinking agent, e.g. divinylbenzene or a di- or tri-methacrylate ester; an elastomer, e.g. polychloroprene or polybutadiene; a polymerization catalyst; and a dodecyl mercaptan. Useful monomers include acrylonitrile, styrene, methyl methacrylate, vinylidene chloride, methyl acrylate, ethyl acrylate, butyl acrylate and vinyl acetate; styrene-acrylonitrile mixtures are preferred. Chloroparaffins are exemplified as the halogen derivative component. The porous cellulosic material is preferably a wood, e.g. ash, maple or sycamore, which may be in the form of veneers or of bulk timber. Polymerization is suitably effected with radiation, e.g. accelerated electrons, ultra-violet radiation, X-rays, gammarays or nuclear reactor radiation. The presence of the halogen derivative improves the fireresistance and other properties of the composite material and, where polymerization is effected with radiation, the halogen derivative reduces the dose of radiation required.

Title: Hollow charge for the production of effects along a line
IPC: F42B1/028
Filed: 1965-08-05
Abstract: 1,255,922. Hollow charges. MESSERSCHMITT - BOLKOW - BLOHM G.m.b.H., and F. R. THOMANEK. 5 Aug., 1965 [9 Sept., 1964], No. 33661/65. Heading F3A. A non-rotating hollow explosive charge is characterized in that the detonation wave is influenced by the structure of the charge and/or a lining of its cavity so as to deviate from the symmetrical axis of the charge to produce a curved spike or a spike of plani-symmetrical cross-section to result in an increased cutting effect in breadth. The object is to produce a non-rotating hollow charge having an increased effect in breadth at the expense of penetration in depth, suitable for the destruction or penetration of extended, thin-walled targets. Eccentric initiation of firing can be resorted to, and a barrier or barriers can be provided, for example, between the initiation point and the lining. The desired effects can also be obtained by means of unilateral dams or shields, recesses and combined explosive charges, i.e. charges in sections with different explosive effects. Bilateral planisymmetrical designs can be resorted to by providing dams, recesses or the like on diametrically opposite sides of the charge. For the production of curved lines of action, the axis of symmetry in the case of the unilateral arrangements has to be formed spirally. A curved line of action can also be obtained if the lining has a corresponding spiral axis.

Title: Improvements in or relating to circuits which include step-by-step electric switches
IPC: H01H67/06
Filed: 1948-12-31
Abstract: 687,652. Electric selective signalling. GENERAL ELECTRIC CO:, Ltd., and ROLLIN, L. Dec. 30, 1949 [Dec. 31, 1948], No. 33666/48. Class 40 (i). Electromagnetic step-by-step switches A, B one of which A, may, as shown, have twice the number of switching positions as the other, are normally stepped to corresponding positions coincidentally and synchronized periodically at a selected position. The stepping magnet 16 of the switch A is, as described in Specification 687,653, pulsed by cam operated contacts 17 at twice the speed of the stepping magnet 19 of the switch B which is pulsed by cam operated contacts 20, the opening of contacts 20 coinciding with alternate openings of contacts 17. Should wiper 5 arrive on a selected bank contact, as shown, the first contact 11, before wiper 7 arrives at its corresponding selected contact 13, a relay 12 is energized over the switch wipers 5, 7 from a source 10 to open the stepping circuit of wipers 4, 5, until wiper 7 reaches its first contact, when relay 12 is short circuited, to permit synchronous operation to be restarted. If, however, wipers 5, 6 are lagging an even number of steps when wiper 7 arrives at its contact 13 the relay 14 functions similarly to relay 12, to open the circuit of stepping magnet 19 until wiper 5 arrives at contact 11, when synchronous operation is resumed as before. Should the wipers 4, 5 be lagging an odd number of steps, however, the wiper arm 7 is halted at its contact 13 as before, but when wiper 5 arrives at its contact 11, it will do so as a result of a step which would not normally coincide with a step of wiper 7, so. that at the next step wiper 5 moves to contact 21 coincidentally with the movement of wiper 7 to the first of its contacts 9. Relay 12 will therefore be actuated to hold the wiper 5 on this contact 21 until wiper 7 has arrived again at its contact 13, when both switches will step with the wipers 4, 5 leading wiper 7 by two steps until the synchronizing position is again reached by wiper 5 where it will be held until wiper 7 catches up and synchronous operation is resumed.

Abstract: 342,757. Measuring instruments ; barometers. RYVES, P. M., 270, Torrero, Zaragoza, Spain. Nov. 5, 1929, No. 33684. [Class 106 (ii).] In measuring instruments with liquid-in-tube indicating means such as thermometers, barometers, &c., errors in reading due to parallax are avoided by providing two sets of aligning marks displaced from one another in the line of sight, the reading being obtained by aligning the indicator with the marks. In one form as shown applied to a thermometer the stem of the instrument, Fig. 1, has, in addition to the usual graduated scale a, a supplementary set of graduations b on the back. The graduations b may be arranged on a separate scale plate d as shown in Fig. 3, the plate being movable to facilitate zero adjustment. Instead of graduating the stem the graduations or aligning marks may be marked on opposite sides of a transparent plate e as shown in Fig. 5. The plate may be arranged at the side of the graduated stem and have sets of marks arbitrarily chosen or the marks may be formed by holes passing through the plate or by pins projecting from its surface.

Title: Improved means for the transverse displacement of metal plates, particularly heavy plates
IPC: B23D33/02
Filed: 1961-09-26
Abstract: 936,430. Metal sheet feeds. SCHLOEMANN A.G. Sept. 26, 1961 [Oct. 1, 1960], No. 34394/61. Class 83 (4).  A means for the transverse displacement of metal plates on roller beds between two shears which trim the side edges of the plates one after the other is characterized in that a plurality of adjustable fences can be coupled together along one side of the roller bed. The apparatus comprises a roller bed 1, shears 2 and 3, a fixed fence 5, and displaceable fences 6 and 7 which position the sheet relative to the shears 3. The fences 6 and 7 are driven by motors 8 and 9 respectively through gears 11a, 11b, 12a and 12b, and the drives can be coupled together by an electromagnetic clutch 13. There is an indicator device 20 and associated with each shear is a scrap conveyer belt. A plate 4 is first carried past the shears 2 which trims one edge in steps, and the plate then slides along the fence 5 and when the leading end is a short distance from the shears 3 the fences 6 and 7 move simultaneously to push the plate to the shears 3, where the other edge is trimmed in steps. When the trailing end of the plate has partly cleared the fence 7 the drive 9 is operated to retract the fence 7 to its original position so that it will not impede the progress of a second plate 4 through the shears 2.
