Abstract: 527,146. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. March 31, 1939, No. 10181. Convention date, March 31, 1938. [Classes 39 (i) and 40 (v)] A valve oscillator comprises one grid 16 at a higher positive potential than the anode 21, a second grid 24 at a negative potential, a tuned circuit 14, 15 connected between the first grid and the cathode, and resonant means such as a piezo-electric crystal 29 for providing feed-back from the first grid to the second. With this arrangement, an increase of potential across circuit 14, 15 results in a decrease of current flowing from this circuit to grid 16 so that a negative-resistance effect is obtained. If the crystal breaks down the valve will continue to oscillate by feed-back through the inherent capacity of the crystal holder and associated wiring. In a modification, Fig. 3 (not shown), the crystal is replaced by a sharply-resonant series tuned circuit which is preferably enclosed under constant temperature and humidity conditions, and a third grid 27, which in Fig. 1 is connected directly to the cathode, is given a small negative bias. The circuit 14, 15 may be tuned to a harmonic of the fundamental frequency.

Patent GB-580685-A (GB)
Title: Improved process for the conversion of hydrocarbon oils
IPC: C10G11/18
Filed: 1943-06-28
Abstract: In processes for the catalytic cracking of hydrocarbon oils containing substantial quantities of salts and like inorganic impurities, in which the oil mixed with a sufficient amount of finely-divided contact or catalyst particles to effect the conversion reaction is passed through a conversion zone and the cracked products are then separated from the particles, contamina <PICT:0580685/III/1> tion of the particles by the inorganic impurities is prevented by removing the salts and the like from the oils before admixing them with the particles.  The desalting may be effected by distillation of the oil to remove light hydrocarbons and water, followed by p filtration of the precipitated salts.  Other methods are described on page 519 of Vol. II of Petroleum Production Engineering (Uren). Where the salt impurities are not wholly removed and are deposited on the catalyst, build up of the impurities is prevented by the loss of some of the catalyst particles by entrainment with the regeneration gases and their replacement by fresh catalyst.  The plant described comprises reactor 70 and regenerator 94 provided with particle separators 78, 106, the cracked vapours passing off through line 82 to the usual fractionating and refining plant while the purified oil from the filter 56 is mixed with regenerated catalyst supplied through line 14 and injected into the reactor through lines 124 or 66.  The velocity of the vapours passing through the reactor may be controlled to maintain the particles in the fluidised condition.  The purification of the oil is effected by passing it through a preheater 14 and heater 18 into a fractionator 24, where gasoline fractions and water are removed and then passing the residual oil to a filter 56 which may be of the rotary drum type employing diatomaceous earth. In this manner the salt content of a Texas crude is reduced from 40-50 lbs. to 1-5 lbs. per 1,000 barrels.

Title: A process of treating grape juice, particularly in the production of wine
IPC: C12G1/04
Filed: 1963-03-19
Abstract: Grape must, immediately after it has been produced from grapes, is subjected to one or other of the following treatments (a), (b) or (c) for a predetermined period of time so as to prevent or inhibit fermentation of the must during that period:  (a) the subjection of the must to a cold temperature which is maintained by keeping the must in a refrigerated container; or  (b) the addition of sulphur dioxide to the must to the extent of between 0.5 and 2g per litre of must; or  (c) the addition of carbon dioxide to the must under pressure, the thus-treated must being kept in a closed container to prevent the escape of carbon dioxide from the must;  which treatment is followed, at the expiry of the period of time, by the steps of taking the must out of the cold temperature or removing the sulphur dioxide or carbon dioxide from the must, and adding pure selected yeast or ferments so that controlled fermentation of the grape juice takes place. When sulphur dioxide is employed, this may be removed by steam heating the must e.g. in thin layers, or by passing a current of air or carbon dioxide through the must.  The yeast or ferments may be added to a quantity of grape juice in a container, the fermenting grape juice thereafter being transferred to other containers so as to effect fermentation of grape juice in those containers. The transference of the fermenting grape juice may be effected automatically under gravity or by using the pressure of the carbon dioxide generated during fermentation.  The fermentation is carried out in an atmosphere of carbon dioxide to prevent oxidation of any part of the grape juice, and the carbon dioxide, aromas and other products given off during the fermentation are collected for use in the process of elsewhere.  The containers may be made of wood, cement or metal.

Title: Improvements in reduced scale shooting gunnery training apparatus
IPC: F41G3/28
Filed: 1947-04-25
Abstract: 623,286. Gunnery training apparatus. ALRIC, G. C. A. April 25, 1947, No. 11126. Convention date, Feb. 9, 1940. [Class 119] The apparatus includes a screen 3 bearing a picture of a landscape as seen from an observation post 4, a projector 2 for projecting on to the screen a spot of light indicating a shell-burst, and a map 12 of the landscape upon which the point of burst is transferred by a mechanical computing mechanism. An element 11, mechanically connected to the projector, is laid on this shell-burst point on the map 12 to orient the projector on the required bearing, and the projector is given the correct elevation, as by a cam 6, after certain data have been obtained from the map 12. In the form shown, a slide 15 can move lengthwise with respect to and can pivot about a point 16 representing the gun position with respect to the map 12. The slide is angularly positioned on a scale 17 graduated to indicate the bearing on which the gun is laid, and a point 18 is positioned on one of a series of equi-trajectional curves 20, according to the given elevation, such curves being drawn from data furnished by range tables and map contours. A device, Fig. 2 (not shown) is used in determining which of the lines 20 shall be used. The element 11 is then laid on a point 19 of the slide 15 to orient the projector, and note is made as to where the point 19 lies with respect to " equi-sight " contours on the map. These contours represent the intersections with the terrain of coaxial cones whose axis is vertical and whose common apex is at the observation post. The reading of point 19 on such contours determines the degree of rotation of a graduated knob 10 which rotates the cam 6 to elevate or depress the projector 2. In another construction, Fig. 3 (not shown), the end of the slide 15 is fitted with a lateral member along which can move over a scale a series of slides corresponding to a number of guns, the member being movable along the scale 17 and the slides determining the position of the slide 15 for each gun. In a modification, the spot of light on the screen 1 indicates the positions of air bursts, such modification being similar in general with that shown, but having means connected to that end of the slide remote from the scale 17 to indicate, according to the fuze time the difference between the ranges to impact and air burst and to impact, from this data, an elevation to the projector.
