Patent DE-3204413-A1 (DE)
Title: Water heater
Inventor: KLIER REINHOLD DR DIPL-PHYS
IPC: F24H1/18
Filed: 1982-02-09
Abstract: In water heaters, it is desirable to avoid the heat of the heated water flowing off to the outside through the water container. For this reason, there is provided in these devices an expensive heat insulation, e.g. made of polyurethane foam, which surrounds the water container and the insulating effect of which, however, decreases greatly in the course of time. According to the invention, the wall of the water container has on its circumference flow ducts which on the upper container edge are connected to the cold water supply and at the lower container edge open into the container space. The cold water flows around the water container, absorbs the emerging heat and returns it to the interior of the container. <IMAGE>

Title: Signal transmitter for monitoring predeterminable moments
Inventor: DANNHORN JUERGEN
IPC: G01L5/00
Filed: 1982-04-24
Abstract: The purpose of the signal transmitter of this device for monitoring moments is, for example, to re-check the braking capacity of a safety brake on presses or the like after each individual stroke. To this end, a specially designed bending bar is provided with a recess on the side of its greatest deflection and a contact element is fastened to this point in an insulated manner. This bending bar is then installed in a clamping body so that it can be loaded in such a way that, when a desired moment is fully achieved, it can deflect in the area of its recess exactly up to a stop point at which the contact element is activated. With the arrangement according to the invention, it becomes possible, without impairing the switching precision, to dispense with the hitherto conventional, displacement-increasing translation devices for transmitting the deflection to a switching device, and to fit the bending bar, which is capable of being calibrated, in the machine housing without further adjustment in such a way as to be protected from dirt and so as to be no longer adjustable from outside and in such a way that very simple, space-saving installation conditions and reliable long-term functions result.

Title: Base unit for intermittent carousel production of mass-produced articles
Inventor: LEUPOLD HERBERT
IPC: B23Q16/02
Filed: 1982-09-07
Abstract: Rotary tables operating in a positive and non-positive engaging manner are widely employed and it is no longer possible to imagine modern mass production without them. Rotary tables with "inner regions" are also produced in the case of larger models. In these cases the indexing bolts or drive bolts always pass through cylindrical rollers, which together with the gear mechanism and drive are likewise outside the rotary table housing. The rotary table construction illustrated here according to Fig. 1 (side view) and Fig. 2 (plan view) differs from the known designs in the following structural features:   1. Radially arranged drive bolts pass through a concave roller (uniform insertion depth in the roller groove over the whole roller length). 2. Subsequent adjustment of the roller and collar ballbearing from the outside is easily possible. 3. In the case of small rotary tables too, an assembly column can be accommodated inside, which was not possible hitherto. This expansion in the field of small rotary tables may be of interest in particular to the relevant, medium-sized industrial sector. <IMAGE>

Patent DE-3317115-A1 (DE)
Inventor: STARCK ALEXANDER DIPL PHYS
IPC: H04N11/04
Filed: 1983-05-10
Abstract: A method and apparatus for transmitting digital luminance and chrominance television signals utilize unchanged PCM codewords and PCM codewords which have been converted into DPCM codewords. The DPCM codewords each contain the difference between the scan values to which they are allocated and the scan values for the adjacent, unchanged PCM codewords. If the amplitude value of an unchanged PCM codeword is B and if the amplitude values of the adjacent PCM codewords are A and C, inverting registers are employed to invert the amplitude value B in relation to the other amplitude values. Adders then form different codewords with the amplitude values A-B and C-B which are encoded in DPCM coders. At the correct time a parallel-series register converts the unchanged PCM codeword and the newly formed DPCM codewords into a time division multiplex signal. Corresponding reconversion is undertaken at the receiving side.

Title: Photocurable ester-ether optic adhesives
Inventor: MAERTIN ROLF DR
IPC: C03C27/10
Filed: 1983-07-01
Abstract: The optic adhesives according to the invention are used for bonding ready-machined optic components to one another under high accuracy requirements to give optical systems. In addition, they can be used for bonding different materials, for example metals to optical assemblies. It is an object of the invention to prepare photocurable ester-ether optic adhesives by stepwise bulk polymerisation of (1,3-dioxolan-4-yl)methyl methacrylates and acrylates. In the first step, brief irradiation of the aligned optic components is intended to achieve immediate fixing. The optic components bonded by the optic adhesive are intended to remain thermally separable over an extended period, and it should be possible in this step to remove the optic adhesive from the separated optic components by means of organic solvents. The final fixing is intended to take place in the second step by thermal polymerisation. The object is achieved by polymerising solutions of (2,2-dialkyl-1,3-dioxolan-4-yl)methyl methacrylate in steps by means of a free radical-forming photoinitiator and a suitable cationic initiator, alone or in combination with 2,2-bis(1,4,6-trioxaspiro-4,4-nonane-2-methyloxyphenyl)propane or 2,2-bis[p-(2-hydroxy-3-methacryloxypropoxy)phenyl]propane.
