IPC: G03B17/14
Filed: 1984-11-09
Abstract: A photographic camera with retractable lens and with housing cover which is coupled to the lens and which can be folded over. The camera is equipped with changeable lenses. The normal lens is held in a longitudinally adjustable holding component in a changeable bayonet socket structure and can be retracted therewith. Telephotolenses can be inserted into the same changeable bayonet socket and rest in this position, from the front, with a collar of their holder, which is greater in diameter, against a plane face of the housing of the camera and draw together the holding component and the housing wall to form a solid holder for the telephotolens.

Title: Serial tetrad adder/subtracter in BCD-8421 code with eight-cycle computing cycle
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1985-01-22
Abstract: In the tetrad adder/subtracter according to the subject-matter of the invention, not all eight part-summands and any carry from the previous addition are processed at the same time but first the part-summands A1 and B1 and any carry from the previous addition. This is followed by the part-summands A2 and B2 and the carry from the previous part-addition for processing and then the part-summands A3 and B3 and the carry from the previous part-addition. In the fourth part-addition, the part-summands A4 and B4 and the carry from the third part-summand addition are processed. Thus, the sum of the two four-digit summands is stored in purely binary code in memory row 5. If this sum number is greater than the number HLLH (9), the binary number LHHL (6) is also added in the sixth to eighth cycle, as a result of which the result number is stored in BCD 8421 code in memories 11 and 22 to 24. <IMAGE>

IPC: B29C45/16
Filed: 1986-09-27
Abstract: The objects produced have a core, for example of foamed thermoplastic material, and an outer skin of, for example, unfoamed thermoplastic material. The intention is to reduce the structural complexity and at the same time ensure that on the one hand mouldings of relatively large volume can be produced reliably and dimensionally stably with reduced material requirement, but on the other hand it is also ensured that the so-called holding pressure can be exerted reliably on the plastics moulding formed in the injection mould. Using an injection head 1, in which on the one hand an inner nozzle 13, 14, 15 for the one material is formed by a tubular insert 7, guided axially displaceably in the housing 4, and in turn contains a likewise axially displaceable needle 9 as shut-off device, and in which an annular nozzle 10, 11 for the other material is formed by an annular space 6 between the tubular insert 7 and the housing 4, and in which finally the shut-off needle 9 has at its free end an extension 18, which in the shut-off position of the inner nozzle 13, 14, 15 terminates at least flush with the free end of the tubular insert 7, this is achieved by the shut-off needle 9 containing at its free end 19 a central nozzle opening 20, which is adjoined to the rear by a connecting channel 21, which has a radial peripheral opening 22. In the wall of the tubular insert 7 there is likewise a longitudinally running connecting channel 24, which has on the inner periphery 8 of the tubular insert 7 a radial mouth 23. At least in the axial position of the shut-off needle 9 corresponding to the shut-off position, the radial peripheral opening 22 of the connecting channel 21 of the shut-off needle 9 can be set, according to choice, into and out of flow connection with the radial mouth 23 of the connecting channel 24 in the tubular insert 7 by relative turning about the common longitudinal axis. <IMAGE>

Title: Method and device for determining the slip between rotating parts
Inventor: STELTER NORBERT DIPL ING
IPC: G01P3/60
Filed: 1986-12-23
Abstract: A method and device for carrying it out enable the slip between rotating parts to be detected in a manner which is simple, safe and of arbitrary accuracy even in the case when a drive-side part has periodically occurring, likewise nonlinear irregularities in the angular velocity and/or angular acceleration. The method and device are distinguished, in particular, in that it is possible to dispense with divisions and with voluminous decoding measures, in particular when for the purpose of evaluating or determining the slip use is made of only one measurement period Tn, which is fixed by the part on the drive side. Furthermore, it is demonstrated how it is possible to dispense with a division of measured values also in the case when a plurality of measurement periods are evaluated.
