Title: Charging of xerographic plates
IPC: G03G15/02
Filed: 1961-03-15
Abstract: 985,663. Electro-photographic apparatus. RANK-XEROX Ltd. March 15,1961 [March 17, 1960],No. 9530/61. Heading G2H. [Also in Division H1] A xerographic plate which includes a photoconductive insulating rectifying layer, allowing current flow in one direction only and being sufficiently insulating in the reverse direction to retain charge on its free surface, is charged by applying across the plate a field having a direction to cause current flow in said one direction so that a charge of opposite polarity to that of the charging member is retained on said surface when the applied field is removed. As shown in Fig. 1, the plate comprising layer 10 of photoconductive rectifying insulating material on a conductive backing 11 is charged by passing a spring loaded roller 20 comprising an inner electrode 21 surrounded by a layer 22 of material having a resistivity between 10<SP>5</SP> and 10<SP>11</SP> ohm-cms, across it twice, the roller drive automatically reversing due to the double helical screw 16. Other modifications show the plate charged by passing it between two rollers having opposite polarities, Fig. 2 (not shown), or by closing a pressure plate on to it, the pressure plate being at high potential, Fig. 3 (not shown). This last device can also be used to transfer a latent image on the surface of an insu-- lating plate to a second plate which has a ratifying insulating layer;the pressure plate being earthed in this application. The rectifying insulating layer 10 of the plate may comprise vitreous selenium doped to render it highly p-type or n-type or alternatively a rectifying barrier layer such as cuprons oxide may be inserted between the vitreous selenium and the conductive backing. In the automatic machine shown in Fig. 5, a drum 67, comprising a photoconductive insulating rectifying lazer 68 on an aluminium backing 70, is rotated through a charging station 71, an exposure station 72 and image induction stations 73 where the latent image is transferred to tape 78, which also comprises an insulating rectifying lazer, e.g. zinc oxide in an insulating binder, on a conductive backing e.g. foil. This image is printed by known means, e.g. using a magnetic brush. The drum may be erased at 75 and recycled, or alternatively, the charging, exposure and erase stations may be rendered inoperative and the machine used as a copier duplicator.

Abstract: 762,695. Artificial legs. VOKES ERNST SCIENTIFIC SURGICAL APPLIANCES, Ltd. June 30, 1955 [April 1, 1954], No. 9640/54. Class 81(2) A dashpot device is incorporated in a knee joint in order to provide one-way'restriction of movement over a predetermined angle, preferably adjacent the "straight" position. A cylinder 2, containing oil, is arranged concentric with the knee joint and is secured to the thigh part 1 of the leg. A radial vane 17 is arranged to rotate with the shin portion but is only effective as a damping means over the angle where it is adjacent an arcuate projection 12. During this part of the leg movement oil can pass from one side of the vane to the other through a duct 18, in a web 11, adjustably controlled by a needle valve 17. Free return movement of the leg is permitted by provision of a non-return valve 15 which allows free passage of oil through the vane. In another form (see Fig. 2, not shown) the vane engages the inner surface of the cylinder over the whole of its movement and oil is transferred by the vane through a controlled duct in a fixed web. A valve in this duct is so controlled by a cam surface, moved by the shin, that the flow of oil is restricted over the predetermined angle of movement.

Title: Improvements relating to amusement devices
IPC: F41J9/02
Filed: 1926-04-14
Abstract: 274,188. Bailey, W. H., and Kneebone, A. April 14, 1926. Ball-shying games.-An amusement apparatus for playing a game of skill comprises a rotating plate having a number of areas marked out or otherwise distinguished as targets and provided with a separate indicating device which, when any one of the targets is struck by a ball or similar missile, is caused by means of connecting mechanism controlled by the target which is struck, to indicate which target has been struck. A motor 17 rotates an apertured disc 2 at the back of which are hinged spring-pressed bars 8 carrying illuminated coloured screens 11 displayed through the apertures 1. When a missile, for example, a rubber ball is thrown or projected against a screen its supporting bar 8 is knocked back and retained by a spring-pressed catch until the catch is displaced by coming against a projection 37 on the frame when the bar 8 returns to its normal position. Before this return, however, the rotation of the disc 2 brings the end of the displaced bar 8 against a roller 23 carried by a lever 24. The lever is thus depressed, and by means of a cord 27 and chain 28 rotates a oneway sprocket wheel 29 freely upon the spindle 30 of a counting mechanism. When the bar 8 has passed the roller 23, the lever 24 and chain 28 return under spring action, retarted by a dashpot, and the spindle 30 is rotated a corresponding amount. A tens drum 31 is secured to the spindle 30 to indicate the added score. The units figure is displayed on a fixed zero plate 38. The arms 8 vary in length according to their scoring values and depress the lever 24 corresponding amounts, the rotations of the tens drum 31 being similarly influenced. The transfer from the tens drum to the hundreds drum 39 is effected by a spring arm 40 on the tens drum engaging recesses in the side of the hundreds drum but held out of the recesses, except at the transfer position, by a stationary cam surface 42. The hundreds drum is retained by a spring-pressed catch 46. To zeroize the indicator the attendant pulls a hand-lever 43 thus withdrawing the catch 46 and allowing the hundreds drum to rotate to zero position under the influence of a weighted portion. The tens drum is zeroized through a lever 24 which is connected to the hand-lever, and is pulled down sufficiently for the purpose according to the judgment of the attendant. To prevent undesirable rebound of the rubber balls light netting may be placed in front of the rotating disc. Shoots may be arranged to lead the balls back to the throwing position. The scoring mechanism may be automatically zeroized after the last of a series of balls has been thrown.

Filed: 1997-09-25
Abstract: A process for the conversion of lutein or of its esters into zeaxanthin by base-catalyzed isomerization is disclosed. The process is carried out by heating an optionally pre-treated lutein-containing material in a mixture of an aqueous solution of an alkali hydroxide and either dimethyl sulphoxide or an organic solvent based on saturated aliphatic and/or aromatic hydrocarbons at temperatures in the range from about 50 DEG  C. to about 120 DEG  C. The process is carried out in the presence of a phase transfer catalyst when an organic solvent based on hydrocarbons is used. Being carotenoids, lutein and zeaxanthin are used correspondingly, especially as pigments for egg yolk, the integuments and the subcutaneous fat of poultry, the flesh and the integuments of fish and crustaceans, as well as foodstuffs. Zeaxanthin is preferably used in many applications, since in comparable dosages it produces a more intensive golden yellow pigmentation than lutein.

Title: Method and device for controlling line-setting elimination
Inventor: CHIKASAWA TSUTOMU
IPC: H04L12/437
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To automatically perform propriety judgment of line setting elimination, simplify the operation of line elimination and also to prevent a misoperation by judging that a line can be eliminated, when it is detected that source nodes ID and destination nodes ID on a reception table on a downstream side of nodes have specific value in nodes on an upstream side. SOLUTION: A line-setting table shows connection destinations of lines and sets them in each different line of transmission directions (E→W and W→E) in every group of reception (RCV) and transmission (TRMT) on one side of a node (EAST side) and the other side (WEST side). When line-setting is eliminated in a certain node, because source nodes ID and destination nodes ID have certain specific combinations on the line-setting table in nodes that are in direction opposite (upstream side) to the transmission direction of a signal, a self-node judges that the elimination of the line is possible by detecting the state.
