Title: Improvements in fluid flow simulation apparatus
Inventor: WILLIAMS RAYMOND WILSON
IPC: G06G7/57
Filed: 1963-05-30
Abstract: 996, 800. Automatic voltage stabilizers. BRITISH AIRCRAFT CORPORATION Ltd. April 7, 1964 [May 30, 1963], No. 21722/63. Heading G3X. A constant voltage circuit comprises a high gain polarity-reversing amplifier with a feedback to an input terminal, and a summing network connecting the input terminal and a reference voltage to the input of the amplifier. In the circuit shown a reference potential E of equal magnitude but opposite sign to the potential required at input terminal X is connected to one branch of a summing network R2 R3 forming the input to the amplifier. It is shown that this circuit maintains a constant potential at terminal X independent of the current supplied to the terminal.

Abstract: 531,576. Motor vehicle dust-excluding engine casings. PORSCHE, F. July 26, 1939, No. 21747. Convention date, Sept. 22, 1938. [Class 79 (iii)] In a vehicle having an elastically - mounted engine the upper part of the engine is shut off from the outside air, in conjunction with body walls 9, 10, by a partition comprising a rigid part 4, 5 and a yielding part 11, 12 the latter part always forming a dustproof connection with the former in spite of movements of the engine relative to the chassis frame. In the construction shown applied to a rear-engine vehicle the rigid plates 4, 5 are secured to the engine and engage between arms 15, 16 of the rubber members 11, 12 secured by plates 14 welded to the body walls 9, 10. The engine is mounted on rubber members 2, 3 and oscillates about a horizontal longitudinal axis S in the same plane as the partition members, each part 4, 5 always remaining in contact with at least one arm 15 or 16 of the rubber members 11, 12. The engine exhaust pipes 6, 7 are preferably below the partition 4, 5. When the engine is removed the rubber members 2, 3 remain in position.

Abstract: 763,601. Stud-and-socket fastenings. CUSS, J. F. July 27, 1954 [Aug. 6, 1953], No. 21803/53. Class 44. A fastener comprises separable mating parts including interengageable spigot and socket means 10, 11, the spigot means 10 comprising a frusto-conical tubular spigot 12 having an apertured inwardly-directed flange 14 within its narrow end, a fastening pin 18 axially displaceable within the spigot between extended and retracted positions, a spring 22 acting between a head 20 on the pin and the flange 14 to urge the pin towards its retracted position, radial locking lugs 26 on the pin beyond the narrow end of the spigot, the lugs and the adjacent extremity of the pin lying, when the pin is in its retracted position within an imaginary conical envelope including at least part of the outer surface of the spigot, and the socket means 11 comprising a frusto-conical socket 27 dimensioned to receive and fit the spigot, a locking flange 30 at the narrow end of the socket and having a central bore 31 and radial slots 32 to permit the locking lugs to pass therethrough on movement of the fastening pin to its extended position whilst the spigot is engaged within the socket, whereafter rotation of such pin to locked position will engage the locking lugs behind the locking flange, and radial locking grooves 33 in the rear surface of the locking flange, the locking grooves being rotationally spaced from the radial-slots to receive the locking lugs and prevent rotation of the fastening pin from its locked position. Removal of the pin from the spigot is prevented in the unfastened condition of the spigot and socket, by a circlip 23. The spigot and socket have flanges 16, 29 respectively for attachment to structures to be fastened. As shown in Fig. 1, the frusto-conical portion of the spigot surface conforms to the shape of the imaginary envelope which is indicated in broken lines but in a modification the spigot has two frusto conical portions, the portion which enters the socket first having a greater degree of taper than the other portion. The socket is correspondingly formed. The containing of the pin within the imaginary conical envelope in its actuated position enables a plurality of spigots secured to a curved structure to engage a similar plurality of sockets on a similarly curved part, provided the sockets and spigots at the greatest relative inclination are not inclined beyond the angle at which the nearest parts of their conical surfaces are parallel. Specification 675,694 is referred to in the Provisional Specification.

Title: A new or improved humus fertiliser and a process for producing the same
IPC: C05F15/00
Filed: 1937-01-11
Abstract: A manure is obtained by adding fish, vegetable or animal oil or fat, with or without bones and/or bone meal, phosphate rock or lime, to peat and digesting the mixture by fermentation by subjecting it to the action of thermophile bacteria so as to hydrolyse the oils and fats and any extracted ossein and to cause their organic combination with the peat humus and the partial dehydration of the mass.  The fermentation may be effected in two stages, in the first by anaerobic bacteria and in the second by thermophile aerobic bacteria, for example as set forth in Specification 487,837.  It is preferable to maintain the pH at about 7,5 to 8,0 by the addition of a substance such as calcium carbonate.  According to an example, moist peat is disintegrated and oil or fat, bones, and lime are mixed with it. The mass is filled into a concrete chamber while being sprayed with sewage sludge.  The chamber is then closed during the anaerobic stage any liquid collecting in the sump being re-sprayed on to the mass. The temperature may be above 50 DEG  C. during the anaerobic stage. The aerobic stage is then carried out the chamber being unsealed and the temperature being allowed to rise to 80-85 DEG  C.  The mass is maintained at the elevated temperature until sufficiently dehydrated, say to 15 per cent moisture content.  A bacteria nutrient such as cane molasses or sugar beet tailings may be added.

[Class 39 (i).] In a luminous electric discharge tube containing auxiliary electrodes 7 in the form of wires or rods arranged longitudinally of the tube 1, each auxiliary electrode being connected through an impedance to a main electrode, the resistance of a unit length of the auxiliary electrodes is lower than that of an equal length of the surrounding gas column. The discharge tube is perferably provided with one or more incandescent electrodes 3 which, in the example are coated with electron - emitting material such as barium oxide and connected to the auxiliary electrodes 7 through resistances 9. Alternatively an inductance or a capacity may be connected between the electrons 3, 7. The auxiliary electrodes may consist of aluminium wires of 1 mm. diameter, with their inner ends extending to the middle of the tube, where they may be interconnected by a small insulating-tube 10, one wire 7 being wound round the tube and the other passed through the tube. The upper auxiliary electrode may be connected through an impedance to the lower main electrode, and the lower auxiliary electrode connected similarly to the upper main electrode. To prevent the superficial disintegration of the auxiliary electrodes they may be coated with' an insulating layer, for example a small porcelain tube or an oxide coating such as is described in Specification 388,302. To prevent the deposition of disintegrated matter upon the wall of the tube a part of the auxiliary electrodes may be surrounded by a grid-like screen. The filling of the tube consists of one or more rare gases, such as neon, to which a vapour, such as mercury vapour, may be added. An anode, which may be of cylindrical shape, may be mounted adjacent to the incandescent cathodes and connected thereto.
