Patent GB-1263078-A (GB)
Title: Apparatus for simulating perceptual phenomena
Inventor: EVANS CHRISTOPHER RICHE
IPC: H04N3/10
Filed: 1968-04-30
Abstract: 1,263,078. Television. NATIONAL RESEARCH DEVELOPMENT CORP. 29 April, 1969 [30 April, 1968], No. 20501/68. Heading H4F. Apparatus for simulating perceptual phenomena comprises a receptor unit incorporating a multiplicity of photosensitive devices arranged in a hexagonal array and a display unit incorporating a multiplicity of light sources arranged in a hexagonal array, each light source being associated with a group of seven photosensitive devices arranged in positions corresponding to the centre and apices of a regular hexagon, signals being derived from the receptor unit only in response to changes in the illumination of individual devices, which signals are used to control the individual sources of the display unit so that an initial illumination of the receptor unit in a given spatial pattern results in a reproduction of a corresponding spatial pattern by the display unit. Specifically, a light source is energized when the central device of the corresponding group of devices is initially illuminated regardless of the state of illumination of the six peripheral devices of the group, but if the light source is not energized in response to illumination of the central device it is energized in response to illumination of the peripheral devices only if for one of the two subgroups constituted by alternate ones of the peripheral devices at least two more devices are illuminated than for the other sub-group. The pattern reproduced by the display unit will be maintained only if appropriate changes are caused to occur in the illumination of the receptor unit, for example by vibrating the pattern of illumination with an appropriate frequency and amplitude or by chopping the illumination at an appropriate frequency. If such conditions are not fulfilled the pattern will subsequently disappear, but different rates of decay are exhibited by geometrically different parts of the pattern such as circular arcs and straight lines, in particular for the hexagonal arrangement described there is no smearing of the pattern reproduced if a vertical line of illumination is slowly moved horizontally across the receptor unit. The circuit arrangement connecting the photosensitive devices to the light sources is described (Figs. 2 and 3, not shown).

Title: Improvements in or applicable to potato digging machines
IPC: A01D19/10
Filed: 1924-09-01
Abstract: 248,120. Morris, A., and Morris, E. J. Sept. 1, 1924. Potato harvesters.-The potatoes are lifted by a share and are thrown sideways by the usual rotating forks j against an indiarubber disc k provided with rubber ribs and mounted on a skeleton frame m adapted to be rotated by chain and sprocket gear x, w', w from the axle c of the main wheels b. The potatoes fall from the disc on to horizontally reciprocating forked members o curved to direct the potatoes into rows. The members o are secured to a frame p having hooked ends q to attach it to rings r on a crosshead s at the end of a connecting rod t actuated by a crank u driven from the axle c. Chains 22 and a link 19 secure the members o to the main frame. A hand lever 9 connected by a link 7 to the connecting rod t adjusts the height of the rear end of the connecting rod. Clutches are provided to control the movement of the connecting rod and the rubber disc.

Title: Improvements in aeroplanes and the like
IPC: B64C21/02
Filed: 1927-08-04
Abstract: 275,638. Freise, H. Aug. 6, 1926, [Convention date]. Sails.-To increase the effect of the wind currents on ships' sails, channels c are attached to the nose of the hollow sail and extend forwardly in the direction of the wind currents. The compressed air in the plane b, in connection with which the invention is described, due to the wind currents entering the channels c passes upward through slots in the top of the plane, and impinges on obstructing surfaces h, between which powerful eddies are formed; the eddies pass through channels between rearwardly-extending slats i, exerting an upward pressure thereon and pass out of the openings m at a speed greater than that of the air currents passing over the outside of the plane, increasing the rarefaction of the air above the plane. The channels c of any suitable shape are attached to channel-like depressions l in the base of the plane, and they are adjustable to an angle with the horizontal, with the elevators if desired, when taking off and landing; the channels may also be angularly adjustable in a horizontal plane. Flaps e may be used to close the channels c when about to land, but are opened again before reaching the ground. 'The upper portion of the plane is formed by hollow lateral members g, which form the passages f, inclined rearwardly at the entrance and then widening and becoming vertical to the plane surface at the top. The obstructing surfaces comprise V-shaped strips h laterally arranged on one arm of which the corresponding slat i is mounted. The said surfaces may be formed by flat slats having short, gentlycurved cones pressed downwardly out of them. The openings m between the slats i are larger than the openings n, all the openings being large enough to allow sufficient air-flow to prevent deflection of the air-currents in front of the channels c. The surfaces h and slats i might also be applied to a plane in which the air entered through slots in the underside.

Abstract: 708,296. Automatic voltage control systems. FERRANTI, Ltd. Sept. 4, 1952 [Sept. 4, 1951], No. 20808/51. Class 38(4) The output direct voltage between leads 17, 24 derived through a rectifier 20 from a supply stage including a valve 10 is kept constant by feeding to a grid of valve 10 a voltage derived through a rectifier 25 fom the voltage across a resistive or inductive impedance 22 in series with a smoothing condenser 21 and a source of bias volts 23 across the output leads.

Title: A process for purifying plumbiferous chloride liquors
IPC: C01G21/16
Filed: 1925-08-24
Abstract: 249,465. Consortium f³r Nassmetallurgie. March 20, 1925, [Convention date]. Addition to 240,401. Lead chloride, carbonate, chromate, oxychloride, sulphate, and other salts. - The solutions of lead obtained by treating plumiferous materials with chloride solutions, as described in the parent case, are purified by treatment with such an amount of a substance alkaline to litmus such as lime, that a small proportion of the lead, for instance 1 per cent, is precipitated. The solutions may be treated after separation from the residues, or in presence of the residues, and after treatment with calcium carbonate and oxidation, for instance with chlorine or chlorates if desired. This treatment precipitates the iron more rapidly than does the process of the parent case. The solution may be treated with more lime, if any iron remains, as shown by testing with ammonium thiocyanate. The solution may be separated :from the residue and precipitate if desired, and is next purified from metals such as noble metals, bismuth, and arsenic, and from excess of oxidizing agent by adding a soluble sulphide in sufficient quantity to precipitate a small proportion of the lead, for instance 0.5 per cent. It is not necessary to neutralize the whole of the oxidizing agent present, as the sulphide precipitate can exist in presence of a small quantity of free chlorine. The precipitates obtained, which contain lead, may be treated as plumbiferous material for extraction by the process of the parent case.

The above process may be extended in that the product is hydrolysed in the presence of a mineral acid such as perchloric acid, to form the corresponding 3-hydroxy compound, the 3-hydroxy compound is oxidised to the corresponding 3-keto compound e.g. with chromic acid, and the elements of H-Y are removed from the 4- and 5-positions of the 3-keto compound with concomitant inversion of the configuration at the 6-position by treatment with a strong mineral acid in solution in a polar solvent with a boiling range of from 50 DEG C. to 120 DEG C. to form a 17a -bromo-6a -haloprogesterone of the formula: <FORM:0946868/C2/3> wherein X represents fluorine or chlorine.  The bromination may be carried out in the presence of a small amount of an organic base such as pyridine, the brominating agent may be N-bromosuccinimide, the catalyst may be benzoyl peroxide, and the removal of the elements H-Y with concomitant inversion of the configuration at the 6-position may be carried out with hydrogen chloride in the presence of chloroform, glacial acetic acid or acetone.  Pharmaceutical compositions having a progestational effect which may be administered orally in the form of a tablet or subcutaneously contain as the active ingredient 3b -acetoxy-5a -hydroxy-6b -chloro-17a -bromopregnan-20-one or 3b  - acetoxy - 5a ,17a -dibromo-6b -fluoropregnan-20-one.
