Title: Method and device for removing sheets or the like from a stack
Inventor: GRENZEBACH RUDOLF
IPC: B65H5/08
Filed: 1984-07-25
Abstract: The invention relates to a method for removing sheets or the like from a stack formed from sheets arranged in an approximately vertical position. When the sheets have large areas, removal of the front sheet from the stack causes considerable problems, owing to adhesion of the sheets. In order to eliminate these problems, the invention provides for the front sheet in each case to be moved away from the stack on an approximately circular or elliptical path, while approximately preserving its position, by which means adhesion is overcome. In a device for implementing this movement, a frame (1) which in each case takes hold of the front sheet (18) of the stack (19) using suction grippers (5) is articulatedly mounted at its lower end on a lever arm (21), which can be pivoted upwards by means of a lifting cylinder (22) (Figure 3). <IMAGE>

Abstract: The invention relates to a desoldering device for multi-pin components on printed-circuit boards. There are various reasons why it is necessary to replace electrical components on fitted printed-circuit boards. Protective handling of the assembly and of the module is necessary during this replacement. For this purpose, the invention provides that a desoldering head 3 be arranged at the upper end of a vertical shaft 2 which can be displaced vertically. The desoldering head 3, whose head plate 5 is replaceable, contains nozzles 4 whose number and position correspond to the arrangement of the connections of the components to be desoldered. The lower part of the shaft 2 is connected to compressed air via a solenoid valve 21 and a spring-bellows angled valve 12 having a vacuum container 1 which is coupled to a vacuum pump 24. Located underneath the desoldering head 3 inside the shaft is a solder trap 6 which is constructed in the form of a pot and whose external diameter is smaller than the internal diameter of the shaft 3, which expands upwards. Openings 8 are provided in the upper, expanded part of the solder trap 6, on its side walls. The upper part of the shaft 2 is surrounded by at least one heating winding 9. A heating cartridge 19 is arranged in the compressed-air supply line. Located above the desoldering head is a cross slide 10 for holding printed-circuit boards, which can move freely in three coordinate directions, and an adjusting device 11. <IMAGE>

Patent DE-3512343-A1 (DE)
Title: 2-bit reflection phase shifter
Inventor: SOLBACH KLAUS DR ING
IPC: H01P1/185
Filed: 1985-04-04
Abstract: In the case of a 2-bit reflection phase shifter, both phase-shifter stages are matched to one another such that the logic combination of the switching states of the two switching diodes of the 90 DEG -bit stage is separated and in each case only one of three diodes still draws current, on average. The essential feature in this case is that the diode at the end of the reflection line loads the line capacitively in the blocked state, and, together with the line piece up to the 90 DEG -bit stage, transforms a short-circuit on its diode on the reflection side.

Title: Method and circuit arrangement for transmitting or storing broadband signals
Inventor: POETSCH DIETER DIPL ING
IPC: H04N11/02
Filed: 1985-05-23
Abstract: For the high-quality transmission and/or recording of broadband signals, particularly of colour video signals as component signals, for example Y, R-Y, B-Y or Y, U and V, via two band-limited channels in real time whilst at the same time improving the signal/noise ratio of the luminance signal or utilising facts of the physiology of the eye for achievable higher bandwidth, a method is proposed in which the broadband signals are subjected to being split into a component having a greater requirement of bandwidth and one having a lesser requirement of bandwidth before they are transmitted or recorded. The sections having the greater requirement for bandwidth are stretched in time and the signal sections having a lesser requirement for bandwidth are compressed in time and during the reproduction, both are reconverted into the original frequency by reciprocal time base changes and are assembled to a signal corresponding to the original signal. The method according to the invention is characterised by the fact that the broadband time-stretched luminance signals are transmitted alternately field by field in two channels and subsequently the unstretched luminance signal and the chrominance signal components are time-sequentially transmitted in the first channel. During the reproduction, the luminance signals of the first field are recovered from the broadband-recorded luminance signals by compression whilst the luminance signals of the second field, by interpolation ...

Title: Method for measuring dimensions by optical contrast, and arrangement for carrying out the method
Inventor: OEHMICHEN MARTIN
IPC: G01B11/02
Filed: 1985-11-27
Abstract: In the measurement of a measuring object by means of an optical contrast measuring method, in which the spacings of successive contrast jumps are determined by counting off exposed and unexposed photoelements, measuring errors or corrupted measurements can occur whenever parts randomly projecting from the surface of the measuring object reach into the measuring field. The shadows of these disturbances simulate incorrect external dimensions of the measuring object. In order to detect such disturbances and to clean up the measurement result, when shading begins a reference counter is started and its counter reading is compared with a prescribed interference suppression reference value. If the associated counter reading is smaller than the reference value, the distance counter is reset. In the event of overshooting of the reference value, counting is continued in the distance counter until the end of the measurement process. It is preferred for the counter reading of a further counter, which is started in the event of shading, to be subjected to a comparison with an interference recognition reference value, it being the case that in the event of overshooting a signal is generated to alarm an operator when it is not a case of the suppression of interference.

Title: Distributing table for tabular workpieces and/or stacks of workpieces
Inventor: ESS WILFRIED
IPC: B27B31/00
Filed: 1985-12-11
Abstract: The distributing table is for tabular workpieces and/or stacks of workpieces which have been extracted from large sized boards by means of longitudinal and transverse cutting. It has a first supporting plane E1, which is composed of driven rollers (2). The said rollers are at a distance from one another in the conveying direction (arrow 11) and leave intermediate spaces in which chains run which are guided over drive rollers. The said chains extend over the width of the distributing table and their planes are at right angles to the supporting plane of the distributing table. They are furthermore supported by a common frame and are mounted such that they can be raised and lowered. The said chains (7) support freely rotatable rollers (9) over part of their length, which rollers (9) form a second supporting plane E2. By raising and lowering the frame supporting the chains, the two supporting planes E1 and E2 can be vertically offset in relation to one another. A stripping straight-edge (15) is arranged on the distributing table on the side of the discharging runs of the chains, which straight-edge can be moved stepwise, in fact in dependence of the width of the rows of stacks. The device described has a larger capacity than distributing tables which do not have the stripping straight-edge, as all the rows of stacks only have to be raised together once to be distanced from one another. <IMAGE>
