Title: Circuit arrangement having a plurality of series-connected shift registers
Inventor: MAIER REINHARD
IPC: G11C19/00
Filed: 1982-07-26
Abstract: In the case of long shift register chains having a plurality of series-connected shift registers, the problem can occur that the data edge runs faster to the input of the respectively following shift register than the clock pulse edge, with the result that data signals can be lost. This problem is solved by the present invention by the clock signals (T) being inverted for successive shift registers (SR1, SR2, SR3). Every second shift register (SR2) has an additional stage (S25). Main fields of application of the invention are airport passenger information systems or large displays. <IMAGE>
Patent DE-3230154-A1 (DE)
Title: Machine for producing a seamless ring
Inventor: BOEDEKER WILHELM
IPC: B21H1/06
Filed: 1982-08-13
Abstract: This machine comprises a three-column press (1), a ring rolling machine (19), and a carousel-type rotatable transport device that are incorporated in one another and functionally linked together. In this way, in addition to a saving in space, a very efficient machining of the blanks is achieved since the multistage compression forming and the finish-rolling of the latter are physically close to one another. The press (1) is loaded with three compression cylinders (8, 9, 10), whose step tools determine the diameter of the production path (17). The latter encloses a rolling position (22) of the ring rolling machine (19), an input station (32) and a removal station (33), and is arranged around one of the three columns. The step tools and the stations (22, 32, 33) and the workpieces located there are operated by three gripping devices (28), uniformly distributed around a circle, of the transport device which can rotate about the aforementioned column. The transport device enables either a single blank to be transported from station to station by the machine, or alternatively several blanks to be held simultaneously in the equipment, so that in the direction of rotation first of all coning punching and then punching-through occurs, followed by final-stroke heading punching and prepunching, and at the same time finish-rolling is performed at the rolling position (22). Forming stations can however also be overshot without operating them. <IMAGE>

Title: Video stereo image method for recording, single-channel transmission and reproduction of coloured three-dimensional perceivable single images
IPC: G03B35/00
Filed: 1982-09-18
Abstract: To record initially two stereo images, two image pick-up tubes are used. However, it is not three colour signals (red, green, blue) which are used in each case but only one colour signal (for example red) by one image pick-up tube and only the two remaining colour signals (for example green, blue) by the other image pick-up tube. These three colour signals are then transmitted like the three colour signals of a single image pick-up tube, are stored and reproduced on a single colour television screen. When viewed through complementary-colour filters, that is to say, for example, in red/blue-green, three-dimensional colour pictures are perceived.

Patent DE-3312360-A1 (DE)
Title: Process for hydraulic conveying of solids
Inventor: ULLRICH HANSJUERGEN DR
IPC: B65G53/30
Filed: 1983-04-06
Abstract: In order to improve the economics of hydraulic solids transport - in particular hydraulic conveying of power station coal and coking coal with water - a coarse-grain solids fraction is mixed according to the invention at the charging station with a fine-grain fraction in such a way that a bulk material of particularly low porosity (and - if represented in the RRS grain size diagram according to DIN 4190 - a low uniformity characteristic, zonally >/= 0.8) is formed. This mixture can be conveyed with a particularly small quantity of carrier medium, that is to say particularly economically. At the receiving station, a classification and subsequent separate dehydration of the two fractions are carried out, before the coarse fraction is also comminuted to the grain size required for further processing. In this way, very extensive drying (dehydration) of the material conveyed is achieved by mechanical, energy-saving means, and this contributes to an improvement in the overall economics. As a result of conveying relatively coarse-grained material, the extraction effect also remains limited, so that the salt loading of the effluent is reduced, as compared with the conventional conveying of fine material, and consequently the expense on effluent treatment is also reduced.
