Patent GB-852908-A (GB)
Title: Food
IPC: A23C11/04
Filed: 1957-07-22
Abstract: A food capable of reducing the cholesterol concentration of the blood and comprising a finely divided vegetable fatty substance whose particles are individually enclosed in a layer of solids obtained by the evaporation and drying of skimmed milk, is prepared by emulsifying the skimmed milk with the fatty substance, and evaporating, cooling and hot air (i.e. spray-drying the emulsion). The process may be modified by adding more skimmed milk after emulsification and before evaporation, and by further emulsification after evaporation and before cooling.  Fatty substances specified are corn oil, soya-bean oil and sunflower oil.  Lecithin is exemplified as emulsifier.  In the example the fat content of unskimmed cow milk is reduced to 0,02% by weight and the skimmed milk is emulsified with corn oil in a ratio by weight of 4 to 1.  More skimmed milk is then added to give a product having a 5,5% by weight fat content, offensive volatiles in the corn oil are removed by evaporation, the product is further emulsified, then cooled and spray-dried to give a powder with a fat content of 40% by weight.  A milk containing 3 to 6% by weight of fat is produced by dissolving the powder in water.

Title: Securing components together
Inventor: COOPE DAVID CHRISTOPHER DIXON
IPC: F16D1/068
Filed: 1966-05-25
Abstract: 1,120,029. Jointing. DAVID BROWN GEAR INDUSTRIES Ltd. 22 May, 1967 [25 May, 1966], No. 23345/66. Heading B3V. [Also in Division F2] A method of securing together male and female components comprises forming the components with a clearance between their mating surfaces, applying to one or both surfaces an adhesive of the type which requires or benefits from curing under pressure at an elevated temperature, pressing the components together while the female component is at a substantially higher temperature than the male component, and subjecting the whole assembly to curing temperature. The invention may be applied to lap-jointing pipes or securing a hub or wheel on a shaft or axle. In an example, a hub is secured to the output shaft of a reduction gear by applying a 0À01-inch thick layer of adhesive to the shaft, which has a diameter 0À005-inch less than that of the hub-bore, and heating the hub to about 70‹ C. in an oven. The expanded hub is now fitted to the shaft in a jig and the assembly placed within an annular heater for curing the adhesive at about 120‹ C. for not less than 40 minutes. Differential expansion during the curing subjects the adhesive to compression, and temperature is controlled by a thermocouple attached to the hub. In another example, the shaft is coated at room temperature with "Redux" (Registered Trade Mark) and the coating dried at room temperature for about 60 minutes. The hub is heated to about 70‹ C. and its bore coated with the adhesive and the adhesive dried by returning the hub to the oven for 10-15 minutes. The hub is again removed from the oven and fitted to the shaft after which the assembly is cured at 150‹ C, for not less than 30 minutes in the annular heater. Alternatively, the hub may be allowed to cool after assembly and before curing. The shaft may be assembled after cooling it with CO 2 . In a further modification, after solvent evaporation from the adhesive at oven temperature, the shaft only is allowed to cool before assembly. The shaft may be located in the hub without a jig if a slight step or steps are provided on the shaft and/or hub. A step may be provided on the hub at one end of the bore and on the shaft at the other end of the bore.

Title: Improvements in echo-sounding apparatus
IPC: G01S15/10
Filed: 1933-08-25
Abstract: 406,592. Echo-sounding and distancemeasuring apparatus. LABOUREUR,L.A. M. J., 19, Rue Bonaparte, Paris, and DUBOIS, R., 3, Rue Michelet, Asnieres, Seine, both in France. Aug. 25, 1933, No. 23674. Convention date, Sept. 5, 1932. Addition to 401,565. [Class 118 (ii).] The system of time measuring described in th e parent Specification is modified by the use of a transformer to flash the neon tube in the time measuring circuit and by the provision of an additional valve to give continuous readings. As shewn in the drawing, when the cam 35 closes contacts to control the emission of the sound, it completes, at 36, a circuit for relay 32 and at 38 the circuit of the primary of 26. Relay 32 operates to discharge the timing condenser 7 or 7 and 9. When the sound has been sent contacts 36, 38 open. Contact 36 releases 32 which, after a slow release pause, closes the circuit to the rectifier 27 in the receiving circuit and opens the short circuit across 7. The opening of 38 causes a current surge in the secondary of 26 which is sufficient to break down the neon tube 24 and allow the potential controlled by 20 to feed to the timing condenser 7. When the echo is received by 29 current flows through 27 and extinguishes the lamp 24. As the grid 6 is at the potential of the timing condenser, the anode current, which is measured on 16, 17, gives a measure of the time elapsing between the transmission and reception of the pulse. To enable a continuous reading to be obtained a second valve 5 and a relay 42 are provided. The circuit of 42 is closed before the circuit of 32, that is, at a time when the potential on 6 is proportional to the reading required. Relay 42 connects the grids 6, 39 of the two valves, a condenser 40 being provided in the circuit of 39 to hold the potential. The value of 40 is at the most 1/10 of the value of 7. As the grids are at the same potential, the anode flow from 5, which is fed to instruments 18, 19, is proportional to the measurement made. The circuit of 42 is opened to isolate the two valves before 7 is shorted so that 39 retains its potential and instruments 18, 19 give a continuous reading. The two condensers 7, 9 may be connected in parallel by switch 8 to give two ranges of operation.
Patent GB-1539321-A (GB)
Title: Sound absorbing coating
IPC: E04B1/84
Filed: 1977-06-03
Abstract: The sound-insulating plate consists of foam and has a uniform relief structure, the upper side of the insulating plate being divided in the manner of a chessboard into square individual fields (F). Each of these fields has a number of ribs (8, 8', 8'', 8''') running parallel to one another with intermediate troughs (9) and the ribs and troughs of laterally adjacent fields (F) run transversely to one another. The relief structure is created simultaneously on two plates by a plate-forming cut carried out in the plate plane, after the foam material has been correspondingly differently compressed by dies having the relief structure. A flat cut leads in this manner, after the compression has been removed, to this relief structure in the cut surface. Square individual fields of the plate lying at right angles adjacently to one another are designed to be complementary to one another so that, by arranging the plates next to one another, a uniform optical effect is created. The plate has a very good sound-insulating effect and can be manufactured in an easy and material-saving manner. <IMAGE>
