Title: Sheet guide unit for rotary printing machine - has guide tongues adjustable to accommodate sheets of different thickness
Inventor: WEISGERBER WILLI
IPC: B41F21/10
Filed: 1975-11-21
Abstract: The sheet guide unit is for directing the sheet into a gripper cylinder on a rotary printing machine. It can be adjusted to optimum conditions to accommodate sheets of different thickness. The sheet is fed by transport rollers onto a feed table and up against registration marks on the cylinder which is fitted with interacting clamping jaws. The sheet guide comprises guide tongues movable periodically up and down around a shaft. The tongues each have a depression on their lower surface to receive any buckled surface on the sheet due to its feed speed being greater than the circumferential speed of the cylinder itself.

Title: Stepper motor drive circuit - attenuates resonance effects by use of intermediate steps of variable step time dependent on full step period
IPC: H02P8/22
Filed: 1975-11-27
Abstract: Resonance effects leading to irregular operation of stepping motors are reduced by the division of each motor step impulse into two parts, but the resulting increase in frequency has limitations on motor top speed. this is overcome by making the intermediate step time variable and dependant upon the time period of the full step. This step variation allows optimum division in the intermediate speed range for the suppression of resonances, and at high speeds allows operation with full step impulses only, thus removing the previous high frequency limitation. The circuits employed may be digital in operation, or the intermediate steps may be generated in an analog circuit from the applied main control impulses.

Title: Meter tariff alterations during operation - using power line signalling to change setting depending on system demand
Inventor: PAESSLER ERNST ROBERT DIPL ING
IPC: H02J13/00
Filed: 1975-12-17
Abstract: The watt-hour meter has a receiver and associated control mechanism for changing the tariff rate in response to a signal sent out along the supply lines by the power authority from a central control. The rate can thus be altered at any time when there is a load trough. Where items of equipment are also controlled by a remote signalling system, a unique channel is provided for the watt-hour meter. The equipment can then also be switched in economic blocks independently of the tariff. The system may be extended to indicate the tariff in operation and also the next anticipated alteration depending on the expected power system load contour.

Title: Difficult or corrosive sludge or sewage sludge removed - by jetting with water recycled from sludge filtering
Inventor: RUHNKE SIEGFRIED
IPC: E03F7/10
Filed: 1976-02-14
Abstract: A method of collecting or extracting, preparing and disposing of sludge, sediments or other waste materials consists of collecting or extracting the sludge by suction or pressure conveying, filtering it over a large-area filter to yield a conc. sludge and sepdd. water, and then recycling the sepd. water to loosen up further quantities of the sludge for extraction by suction or pressure. The conc. sludge after filtering is then dried in channels possessing outlet openings at the bottom to permit drainage without re-humidifying. Finally, the dried sludge is further dried in internally aerated heaps. Pref. the sludge to be extracted is loosened up by jetting the recycled water onto it. For handling and treating either sewage sludge or industrial waste of toxic, corrosive or similar harmful nature. The method can be applied in particular to the removal of sludge from containers which must possess internal anti-corrosive linings which limit the use of excavating equipment due to resultant damage to these linings. It enables the total drying and storage areas to be considerably reduced and the amt. of water initially applied to the process to be kept at an absolute min. since the water needed for loosening up the sludge is almost exclusively provided by recycling.

Inventor: QUICKER HERBERT
IPC: E06B3/968
Filed: 1976-03-06
Abstract: The stabilising and aligning element (25) is of a slightly smaller width than the groove width of a structural profile of a window- or doorframe. The stabilising and aligning element (25) can thus be inserted from outside into a groove having said groove width and, thereafter, can be displaced into a position in which it covers a joint (11) of the two adjacent structural profiles, the window- or doorframe consequently being stabilised and aligned. Such a stabilising and aligning element (25) can also be installed subsequently, after the window- or doorframe has been mounted. <IMAGE>

Title: Electronic water temp. control circuit - uses temp. sensor difference signal mixed with timing pulse in control amplifier to actuate solenoid operated mixing valves
Inventor: MERZ KLAUS PHILIPP DIPL ING DR
IPC: G05D23/13
Filed: 1976-04-03
Abstract: The electronic water temperature controller for hot and cold water mixer valve systems consists of magnetically-operated valves, one in each of the cold supply line (M1) and the hot water supply line (M2) which are opened and closed according to control signals. The electrical signal from a temperature sensor (F) in the mixing chamber (3) is combined in a control amplifier with signals from a timing pulse generator and from a temperature reference element set to the desired final temperature. The difference signal produced provides a control amplifier output signal which is used to drive a relay which in turn controls the solenoid-operated valves in the supply lines. The system operates with a rapid response time and little overshoot.
