Patent GB-668286-A (GB)
Abstract: 668,286. Beverages. BRUINIER, J. G. Nov. 1, 1948, No. 28311/48. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 7, 1949.] Class 14 (ii). In making alcoholic beverages having the taste and alcoholic strength of wine by subjecting a liquid containing a plant extract and fermentable sugar to an alcoholic fermentation process, the liquid to be fermented is formed by preparing an aqueous extract from plant parts of foliage, leaves, stalks or root stocks of graminaceous plants, clovers, vegetables in the fresh condition of the growing plants, hay or straw, and to it may be added substances commonly used for promoting alcoholic fermentation in amounts conducive to the production of a fermented liquid of the desired alcoholic strength. There may also be added to the mixture a small amount of aromatic plant parts or extracts and/ or other plant juices and/or fruits, fruit pulp, juice or must. Wines of poor taste and quality may be improved by adding to them an aqueous plant extract as described above. In an Example 1 part grass (or “ part hay) is boiled with 4 to 5 parts water and sieved giving about 4¢ parts liquid in which sugar is melted in an amount corresponding with 270 grms sugar/litre of solution. The juice of 50-100 grms grapes, cherries, prunes or berries/litre is then added with if desired 0.5 grm of a mixture of (NH 4 ) 2  PO 4  and (NH 4 ) 2 SO 4  and the mixture subjected to fermentation, yeast or a yeast culture being added if necessary. Specifications 147,496, [Class 14 (ii)], and 365,942 are referred to.
Patent GB-720468-A (GB)
Abstract: 720,468. Electromagnetic couplings. ENGLISH ELECTRIC CO., Ltd. March 28, 1952 [April 5, 1951], No. 7937/51. Class 35. [Also in Group XXIX] An electro-hydraulic device comprises a housing, a magnetizable rotor within the housing, co-operating surfaces in the housing and in the rotor arranged to define an annular duct, the surface in the housing being formed of non-magnetic material, and means for creating a stationary magnetic field extending across the duct whereby if the duct is connected to a source of magnetic fluid, the fluid as it comes under the influence of the magnetic field will congeal and lock with the rotor but not with the stationary surface of the duct. A hydraulic coupling comprises a non-magnetic housing 10 having two rotors 15, 16 mounted therein on shafts 17, 19. Each rotor comprises a number of discs 21 each comprising a number of magnetizable segments secured together on a non-magnetic bush and separated by non. magnetic material. The discs 21 are mounted on the shafts and spaced from each other by spacers. 22. A speed-ratio control shaft 41 extends through the housing between the rotors 15, 16 and carries a non-magnetic control member 43 dividing the housing into upper and lower halves. One end of the member 43 cooperates with a cylindrical surface on a non- magnetic dividing piece 44 which is provided with vanes 46 which extend into the spaces between the discs of the rotor 16; the other end of the member 43 is formed with vanes 45 which extend between the discs of the rotor 15. A further non-magnetic fixed dividing piece 47 is provided adjacent the rotor 15. Fixed non-magnetic mixing vanes 48 are provided in the lower half of the housing. The rotors 15, 16 are straddled by electromagnets 35, 36. The housing is filled with a magnetic fluid, e.g. finely divided ferro-magnetic particles suspended in light oil, which when it comes under the influence of the magnetic field locks with the rotors so that when the shaft 17 is driven fluid is circulated to the rotor 16 to drive the shaft 19. Speed ratio is controlled by the vanes 45 which permit varying amounts of fluid to circulate round the rotor 15. The magnetic fields may also be varied or may be provided by permanent magnets. The housing has a filling plug 51 with a vent valve 52, air exhaust plugs 53 and a replenishing tank 55 connected to the interior of the housing by a pipe 56 fitted with a non-return valve 57. A spring-loaded ball valve 50 is fitted in the member 43 between the top and bottom halves of the housing. A single rotor device may be used as a pump or motor, and one such device may be used with a normal pump or motor (using magnetic fluid). The rotors may be tapered or spherical.

Title: I.C. engine valve assembly
IPC: F01L3/22
Filed: 1978-08-18
Abstract: The assembly has a valve 3 and a valve cate 1, affording a seat 10 against which a face 11 of the head of the valve seats and includes means 8 for cooling the seat. In order to make the valve face 11 and the valve seat 10 resistant to corrosion, they are each provided with armouring, the armouring of the valve face being harder than that of the valve seat. Owing to the relative hardness of the armourings, any combustion residue will not be deposited on the valve face but it may be pressed into the valve seat. However, the seat will be at a temperature at which the combustion residues will not corrode the valve seat. The valve seat may be provided by an annular element 9 welded to the cage. <IMAGE>

IPC: B01D53/04
Filed: 1979-08-24
Abstract: Respiration air for use (14) in the pressurised cabin of an aircraft is entirely produced by the removal of nitrogen from compressed air by means of reversible adsorbers (5) operated in a cycle comprising adsorption and reverse desorption phases, such that during each adsorption phase a continuously increasing proportion of nitrogen passes to the outlet end of the adsorber, and the oxygen concentration of the respiration air formed is adjusted in accordance with the cabin pressure within a permissible range by controlling the amount of gas flowing through the adsorbers, e.g. by a valved outlet (9) from a buffer tank (8) for the respiration air, and/or the ratio of adsorption to desorption pressure, e.g. by desorbing at the external pressure. An adsorber for use in the method has a casing containing an adsorptive filling and provided with spaced internal dividing plates having ports at opposite ends so as to form a zig-zag flow path for the air through the filling. <IMAGE>

Title: Digital Video Correlator
IPC: G01S3/786
Filed: 1980-01-09
Abstract: A digital video correlator wherein a reference image and a live image are digitized and compared against each other in a shifting network to determine the correlation or degrees thereof existing between the two images. A video digitizer (14) divides live and real images from various sources into picture elements and digitizes (Figure 2) those elements to fixed voltage levels. The digitized live image is passed to a dynamic memory (16) consisting of a plurality of interconnected shift registers (Figure 3) while the digitized reference image is maintained within a first set of shift registers comprising a portion of a processor (20). A second set of shift registers within the processor (20) maintain therein a mask function to select that portion of the reference image to be compared with the live image (for tracking onto a specific portion of the reference image. Yet a third set of shift registers within the processor (20) are interconnected in parallel to the dynamic memory (16) to receive, under control of a clock (23), the digitized data of the live image. As the live image data is shifted through the third set of shift registers, single-bit correlators interconnecting corresponding bits of each of the first, second, and third sets of shift registers, compare the digitized values of the corresponding bits, with such comparison being enabled or negated by the mark function. The outputs of all the single- bit correlators are summed together with that sum indicating the degree of correlation, on a bit-by-bit basis, between the live and reference images (Figure 6 and 7). Further circuitry (22) is included to determine the point of best correlation between the two images and to normalize or take the mean value of the correlation output. <IMAGE>
