Patent DE-3740681-A1 (DE)
Inventor: ROEHRDANZ ALBRECHT DIPL ING
IPC: B65B51/00
Filed: 1987-12-01
Abstract: The invention finds application in twist heads for packing sweets in twisted wrappers, where the opening and closing movements of cranked twist-grippers 13 are effected by means of a reciprocating internally toothed claw 10. It is the problem of the invention to prevent the stoppage times of the packing machine due to faults in the opening and closing movements of the twist-grippers as a result of penetration by sugar dust and to reduce the maintenance expense. To this end, each gripper is mounted on a respective one of a pair of axially aligned stub shafts 11 extending into the interior of a housing to which is fast with a rotatable tubular shaft 1 and completely sealed from the exterior but which communicates through openings 7 and 8 and shaft bearing 3 with the interior of a further housing 4 accommodating the shaft 1 to permit oil mist therefrom to penetrate the housing 6. The view ends of the stub-shafts mount gear segments 12 which are arranged one above the other within any lateral offset along axis of the shafts and in engagement with the claw 10 which is carried at the end of a reciprocable rod 2. <IMAGE>

Title: Process for the low-polluting heating of coke ovens, and coke oven for carrying out the process
Inventor: HOELTER HEINZ DIPL ING
IPC: C10B21/18
Filed: 1988-03-10
Abstract: A gas-heating device for coke ovens, consisting exclusively of a lean-gas heating system, can nevertheless be supplied with rich gas or lean gas, if there is a blast furnace gas supply from a metallurgical coking plant. For this purpose, flue gas is taken via a by-pass line from the flue gas duct and combined in a mixing station with the rich gas supplied in the rich gas line. The precise rate is determined via orifice plates in both lines and a valve in the rich gas line is controlled via a controller in such a way that an exact mixing ratio is always ensured in the mixing station. Via downstream measuring instruments, the quality of the lean gas can then also still be varied under control by corresponding feeding of mixed gas or rich gas, so that coke oven operation which is advantageous in quality and in the output of nitrogen oxides is possible. <IMAGE>

Patent DE-3810572-A1 (DE)
Title: Device for radial support of a cylindrical side reflector constructed of graphite blocks
Inventor: HORNISCHER EDGAR DIPL ING
IPC: G21C5/08
Filed: 1988-03-29
Abstract: The invention relates to a device for radial support of a cylindrical side reflector made of graphite blocks on a thermal side shield which surrounds it at a distance. The side reflector is provided for taking up the core of a high temperature reactor, formed from spherical fuel elements, and must take up the forces from the pouring in of the fuel elements as well as the forces arising when driving absorber rods into the core, which only become effective during shut-down procedures. In order to avoid the large support forces necessary in the latter case being continuously transmitted into the side reflector, the device consists of two spring packets, coaxially arranged and differently pretensioned, which are screwed together to form one unit. An adjusting element is provided for each spring packet, with which exactly defined spring paths can be set. The pretensioning forces to be set altogether and which are to be determined from the maximum loadings of the side reflector, are distributed to the two spring packets by means of parallel-connected spring packets and, in the case of spring packets connected one behind another, are exerted by the outer set of springs.

Patent DE-3831353-A1 (DE)
Title: Pressure regulator for a pressure medium installation
Inventor: DEIKE KARL-HEINZ ING GRAD
IPC: G05D16/10
Filed: 1988-09-15
Abstract: A known pressure regulator has an outlet valve whose valve element is moved in an operational idle phase by means of a shut-off piston and, on the occurrence of a highest permissible safety pressure, is moved by means of this safety pressure to open the outlet valve. In the known pressure regulators, the shut-off piston and the valve element are integral. Therefore, when the safety pressure occurs, the shut-off piston is moved with the valve element, which results in variations of the safety pressure. To reduce the variations by simple means, the invention proposes to arrange the valve element (15) so as to be movable in a sealing fashion relative to the shut-off piston (5). The preferred field of use of the pressure regulator is a pneumatic motor vehicle braking system and/or control system. <IMAGE>
Patent DE-3833653-A1 (DE)
Title: Hydraulic accumulator
IPC: F15B1/14
Filed: 1988-10-04
Abstract: The invention relates to a hydraulic accumulator (1) with a housing (2, 3) and diaphragm (7) capable of flexing which divides the interior of the housing into a gas space (16) and a fluid space (15) in each case of variable size. The stroke of the diaphragm (7) is limited by a fixed dividing wall (10) provided with at least one flow opening. In order to obtain reduction in the diffusion through the diaphragm (7) at least for the cases in which pressure medium has to be made available for longer periods and is consumed and re-filled in a shorter time, the dividing wall is gas-tight and formed in such a way that the unextended diaphragms turned up around their restraint can bear tightly, i.e. without forming annular spaces or "gas nests". The invention makes use of the observation that diffusion cannot take place if a diaphragm is not dampened by gas or if a gas discharge is made impossible. <IMAGE>
Patent DE-3836604-A1 (DE)
Title: Cross-cutter for material webs with a downstream depository for the cut sheets
Inventor: VITS HILMAR
IPC: B65H29/68
Filed: 1988-10-27
Abstract: The invention relates to a cross-cutter with a depository for the cut sheets. So that, during a positive conveyance of the cut sheets, the sheets can be deposited in a fault-free manner in rapid sequence, a combined conveying and braking device 20-31 is arranged behind a conveyor device 8, 9. This combined conveying and braking device 20-31 takes over the positive conveyance of the sheets when these leave the preceding conveyor device 8, 9. By means of deflecting and guiding cams, the sheets are deflected out of the conveying plane and conveyed first by a conveying cam 22 via guide elements 30, the rotational speed of the conveying cam 22 determining the conveying speed as a result of the high coefficient of friction. While the conveying cam 22 is still conveying the sheet positively, a downstream braking cam 23 strikes the guide element 30 which, however, as a result of the low coefficient of the guide element 30, does not yet have a braking effect on the sheet. Only when the conveying cam 22 leaves the end of the conveying and braking device 20-31 does the braking effect become active. This takes place in that the braking cam 23 presses the sheet against the braking ring 31b of the shaft 31 which rotates at the braking speed and which has a high coefficient of friction. The sheet thereby deflected allows an overlap of its end with the start of a new sheet. <IMAGE>
