Title: Method of producing elliptic core type polarization-maintaining optical fibre
Inventor: KAJIOKA HIROSHI
IPC: C03B37/012
Filed: 1989-05-26
Abstract: A method of producing an elliptic core type polarization-maintaining optical fiber comprises providing a glass rod comprising a cladding glass layer around the periphery of a core glass layer, the cladding glass layer having a softening point higher than the softening point of the core glass layer, removing two side surface portions of the glass rod to form a machined rod noncircular in cross section, outside depositing fine silica glass particles on the periphery of the machined rod, followed by sintering to provide a support glass layer having a softening point higher than the softening point of the cladding glass layer, and drawing the thus obtained glass rod body as an optical fiber preform. Since the portion for constituting the core of the optical fiber is formed by machining, the core is permitted to have a high ellipticity. An optical fiber with the desired size and birefringence index is obtained by regulating the conditions of production.

Title: Concealing errors in a video signal produced by telecine
Inventor: MASSMANN VOLKER
IPC: H04N5/21
Filed: 1990-12-20
Abstract: An error in a video signal produced by television film scanning and resulting from a substantially vertical film scratch SF crossing a sloping edge k on the film picture is concealed by comparing in successive lines the image point value preceding one side of the scratch X0 with the image point value following the opposite side of the scratch X1 to determine where the sloping picture edge k enters and leaves the scratch. The coordinates (x0y0) and (x1y1) and corresponding values of the image points where the sloping picture edge enters and leaves the scratch are stored. For each line between where the sloping picture edge enters and leaves the scratch the co-ordinates of a cross-fading point U1-Un are calculated, the coordinates of the cross-fading points together at least approximately corresponding to the part of the sloping picture edge missing in the scratch. Cross-fading is then performed between the stored image point values in the region of the calculated cross-fading point in each line between where the sloping picture edge enters and leaves the scratch. <IMAGE>

Title: Generation of random conversation testcases.
Inventor: BIRD DAVID L
IPC: G06F9/46
Filed: 1993-03-30
Abstract: A method of generating pairs of random inter-program conversation testcases in which conversation statements are selected (210) to construct the testcases in dependence on what statements are permitted for the predicted current conversation states. The effect of each statement is predicted (240) from predefined state tables for particular conversation protocols. As each conversation-type statement is added to a testcase, it is determined whether matching statements must be added to the other testcase and, if so, these matching statements are randomly generated (230) in the same way. Self-checking code is added (230, 250) to the testcases to check correct execution. The method is particularly suitable for testing the support of asynchronous conversations between transaction processing programs running in different CICS systems. <IMAGE>

Filed: 1993-10-11
Abstract: A hydrostatic drive system, particularly for an excavator, comprises a demand regulated pump and a plurality of consumers (6, 8) actuated by respective directional control valves (5, 7), which perform a throttling function in intermediate positions, and which downstream of the valves (5, 7) are connected via non-return valves to a load-sensing line (12). To enable one or more of the consumers (6) to be supplied with priority with pressure medium in specified operating states, so that, especially in the event that the pump delivery capacity is saturated, no reduction occurs in the speed of movement, a priority valve (32) is connected into the LS-line (12) in such manner that in a first operating position of the priority valve (32) the line sections (12b) downstream of the non-return valve(s) of the non-priority consumer(s) (8) are connected to the LS-line (12), and in a second operating position they are connected to a line (4b) which conveys the delivered pressure of the pump. The priority valve (32) is acted upon in the direction of the first operating position by the delivered pressure of the pump and, in the direction of the second operating position, by an adjustable spring and, in the case of the actuation of the priority consumer(s), additionally by the load pressure of this (these) consumers (6). This additional load pressure is applied to the valve (32) by actuation of a valve (34) which is operated simultaneously with the valve (5). When pump pressure is not sufficient, the valve (32) moves to its second operating position to effect closure of auxiliary valves (10) in the valve(s) (7) of the non-priority consumer(s) (8). <IMAGE>
