Patent DE-3807885-A1 (DE)
Title: Pivotable-axis step-by-step rack mechanism
Inventor: GOLLHARDT HELMUT
IPC: B21K1/46
Filed: 1988-03-10
Abstract: The invention relates to a pivotable-axis step-by-step rack mechanism, preferably for double-stroke boltmaker presses, for the stepwise transport and positioning of a tool holder. In this mechanism, a tappet interrupted by spring assemblies is moved by means of two gear blocks, on the front side of which double cams are provided, via a rocker to control a known device for positioning the tool holder. A pivoted lever in which a splined shaft with a gradually disappearing rack profile is mounted, controls the oscillating motion of the splined shaft via a second double cam and thereby ensures rotation out of engagement with a pinion which, in turn, is firmly connected to a gear wheel which drives the toothed part of the tool holder in a stepwise manner. The movement of the splined shaft in the horizontal direction is accomplished by means of a slot cam in which a device with a roller guide firmly connected to the splined shaft is guided. <IMAGE>

Patent DE-3831611-A1 (DE)
Title: Transition coupling between a plastic pipe and a metal pipe
IPC: F16L37/088
Filed: 1988-09-17
Abstract: The transition coupling between a plastic pipe and a metal pipe is achieved via a spring ring which engages into an encircling outer groove in the metal pipe. The plastic pipe is provided with a socket, sealing being effected in the interior of the socket by O-rings located in inner grooves. For a reliable transition coupling which can be handled simply, it is proposed to equip the socket with an annular chamber which exhibits metallically reinforced chamber walls in which the spring ring is arranged such that it can move radially. Consequently, the socket forms, together with the spring ring, a prefabricated structural unit which acts like a female-mould closing part of a push-button-like snap-type closure because the metal pipe equipped with the outer groove acts as the closing head of a push-button male-mould part which snaps in there by the two plugging axially one into the other.

Inventor: KIEFER ERICH DIPL ING
IPC: B29C48/475
Filed: 1989-11-01
Abstract: The invention concerns a process for the production of hollow bodies made from thermoplastic material by extrusion blowing. The process calls for discontinously produced preforms to be stretched in a blowing mould. During at least part of the extrusion-head loading phase typical of a process of this kind, the distance covered by an ejection piston (19) associated with the storage space (18) and the speed with which the ejection piston (19) is forced through the plasticized material in the storage space (18) are measured and each compared with a target value by a central control unit. Depending on the result of this comparison, at least one process parameter, e.g. extruder (10) throughput or ejection-piston (19) delivery-stroke length, can be adjusted in the same cycle so that substantially the required preform volume is ejected.

An adhesive layer (5) retains the substrate on the support which carries conductive tracks (4) for the converting element. A light shield eliminates stray light. A light adjuster enusres uniform light distribution.

Title: Scanning large flat images for electronic storage and processing - using small hand scanner mounted in plotter covering large areas with accurate alignment of adjacent scanned sections
IPC: H04N1/107
Filed: 1990-05-25
Abstract: Conventional image scanners for large images are generally complex and expensive. Cheaper hand-held scanners can  only scan narrow image strips, creating the problem of how to align the scanned strips in a large image. The problem is solved by mounting a hand-held scanner (1) in place of the pen in a plotter, and using software to drive the plotter to scan the image (2) in a regular, precise strip pattern. Accurate alignment can be achieved using standard slip-correction software for the plotter. ADVANTAGE - Cheaper than large image scanner with similar performance.

Title: Flame cutter - has identical two=way valves in oxygen supplies and three=way valve for fuel gas supply for gas pressure control
Inventor: BAMBACH REINER
IPC: B23K7/00
Filed: 1990-06-06
Abstract: In the control system for a flame cutter, the valves (17,18) in the O2 supply lines are identical two-way valves. The valve (16) in the fuel gas line is a three-way valve. Pref. the O2 supply valves (17,18) each have two selectable electro-magnetic valves (46.49) and sensors (50,51) with electronic valve controls (19,20). One electro-magnetic valve (46,48) is between the inflow openings and the control zones of the regulating pistons, and the other electro-magnetic valve (47,49) is between the control zones and the relief outlets. The sensors (50,51) generate actual value signals for the values in the low-pressure valve chambers, which are constantly compared with nominal values from the flame cutter control (12) by the electronic valve controls. According to the signal for the difference between actual and nominal values, the electro-magnetic valves (46,49) are opened or closed to raise or lower the oxygen supply (38,39) pressure. The valve (16) in the fuel gas supply has a control magnet (84) and a sensor (85) with an electronic magnet control (21). The control magnet (84) is connected to a control piston (91) which forms the valve seat (92,102) with the main piston (93). The main piston (93) is held by a spring (94) against the action of the control magnet (84). The valve seat (92,102) is opened or closed according to the ratio of the magnetic force to the force from the low-pressure valve chamber (90). ADVANTAGE - The assembly gives a simple control for the required gas pressures for the flame cutting according to the nature of the workpiece.

This step is repeated until the established power level is exceeded, whereupon the original output voltage of the source is varied by the predetermined number of steps, which is reduced to one and the source voltage maintained at max. power level. USE/ADVANTAGE - Pref. for battery-charging from solar or wind power plants. Max. power-point operation is unaffected by environmental changes such as sunlight fluctuations.

Patent DE-4025022-A1 (DE)
Title: Annealing non-ferrous metal strip in floating strip oven - where thicker strips of metal are supported in denser inert atmos.
Inventor: STRIGL REINHARD DIPL ING
IPC: C21D1/76
Filed: 1990-08-07
Abstract: A process for annealing non-ferrous metals at 750-850 deg. C in a floating strip oven using a H-contg. protective gas (PG) atmos. is claimed. The innovation is the use of Ar in the PG which has a higher density than N, and in admixt. with H adjusts the density of the PG favourably to aid the buoyancy of the floating strip. The ratio of Ar in the PG is pref. more than 50%, esp. good is 100% Ar mixed with 35% vol. H. The Ar can also be mixed with other inert gases eg. exogas, and the inlet and outlets of the annealing oven are sealed with a N purge. USE/ADVANTAGE - Thicker strips of metal can be effectively annealed. The use of a denser PG atmos. widens the scope of this specialised technology. In an example, at 800 deg. C the densities of Ar, N, and H are in the ratio 0.45:0.31:0.023, so by substituting N by Ar the density can be enhanced by about a third. A PG atmos. of 20%H 80%N can support an annealing brass strip of thickness 0.9mm, but not a thicker one having thickness 1.3mm. This thicker strip can be supported by adjustment of the PG atmos. using Ar addn, then successfully annealed in the floating strip oven at the appropriate temp..

Title: Making substrate to hold floor heating - by heating and moulding plastic film into sheet with hollow pipe holders, filling holders with granules, and bonding foam
Inventor: LUECKE ROLF
IPC: B29C44/12
Filed: 1990-08-21
