Patent DE-2948630-A1 (DE)
Title: Pneumatically-operated spray cleaner for paper-making machine - with hydraulic speed-regulator having two chambers connected by constricted passage
Inventor: HAMMELMANN PAUL
IPC: D21F1/34
Filed: 1979-12-04
Abstract: A reciprocating spray tube for a papermaking machine using re-cycled water which is unsuitable for operating the reciprocating mechanism has a double-acting pneumatic drive unit with a hydraulic check motion to control the reciprocation speed. Along the axis of the piston which drives the unit is an oil-filled tube, divided into two sections by a fixed piston through which is a narrow passage connecting the two sections, and through which the oil is driven by the motion of the tube, at a speed which is determined by the size of the passage. This construction provides a compact pneumatic drive unit with an in-built traverse speed-control.

Title: Adjustable clamps for assembling hollow profiles - to form curved boat hull bodies for building various hull forms without using solid moulds
Inventor: PFLEGER ALBERT
IPC: B63B5/24
Filed: 1980-02-04
Abstract: A system for constructing boat hulls by assembling a series of hollow profiles to fit curvatures imposed by the edges of a limited number of transverse formers and bulkheads (plus transom, keel and stem profiles) involves use of a series of 'U' profile clamps, pref. made of spring steel, carrying threaded rods which can project various distances to converge upon the required simple or complex hull curvature form. The edges of the hollow profiles which form the core of the hull walls engage semi-positively, by having radiused edges which locate in 'V' faces on the edges of the adjacent profile: asymmetric profiles may be mounted head-to-tail or profiles with twin 'V' edges may be assembled via tubular profiles, esp. where a sharp change of chine is reqd. The profiles are bonded or fused at intervals to each other and to the edges of the formers, and the interstices of the radiused/'V' profile joints are filled in with reinforced resin to obtain flush internal and external hull wall faces. Suitable for producing a wide variety of boat hull sizes and shapes without involving costly complete individual negative moulds.

Title: Control circuit for inverter-fed asynchronous motor - uses multiple frequency adder and divider stages to compensate for rotor slip
Inventor: BLAHNA JAROSLAV DIPL ING
IPC: H02P27/06
Filed: 1980-02-19
Abstract: The method of controlling the supply frequency for an asynchronous motor fed by an inverter so that slip is compensated for taking into account the number of pairs of poles for the motor. The motor frequency is altered in the same direction, corresponding to the motor speed, increasing proportionally. The control circuit uses a current controller stage which receives signals from the motor and enters control signals into the inverter. A frequency adder stage receives signals from a rotary position emitter connected to the motor shaft, these signals being proportional to the speed of the motor, being sum of difference signals corresponding to whether the drive acts as a generator or brake. The adder stage is preceeded by an extra frequency control stage connected to an oscillator, forming an extra loop which also receives the frequency signals proportional to the motor speed. The extra stage includes a divider for the motor frequency followed by an adder which adds control signals corresponding to the motor frequency. The motor frequency can be increased by multiplying the motor speed signals.

Patent DE-3009237-A1 (DE)
Inventor: GIERTZ FRANZ DIPL ING
IPC: F01K23/06
Filed: 1980-03-11
Abstract: A method and apparatus for power and/or heat generation from fuels. The fuel is fed to a combustion chamber and a pressurized gaseous oxidizing agent is fed to the combustion chamber to fire the fuel in a fluidized bed. The smoke gases coming from the fluidized bed are cooled, purified in a purifier such as an electrostatic filter, reheated in a heat exchanger immersed into the fluidized bed and fed to the gas turbine. The exhaust gas from the gas turbine is fed to a recuperator for gaining the residual thermal energy and is then released through a chimney. The cooling of the smoke gas can be achieved by adding compressed air to the smoke gas stream or by introduction, e.g. into the upper half of the combustion chamber of a water or steam operated heat exchanger.

Title: Stuffed pigs-belly mfr. - saves manual sewing by using end clamp and hollow scalding mould
Inventor: SCHMIERSMEIER GUENTHER
IPC: A23L13/00
Filed: 1980-06-26
Abstract: Stuffed pigs belly is produced by filling the belly from the opened sides with minced sausage meat and placing it into a two-part clamp which closes one of the two ends. The pigs belly is then placed in a hollow mould and scalded in a boiler and finally passed through a smoking chamber. The pigs belly is opened up at both ends, placed in a clamping device which keeps one end closed and stuffed with sausage meat by joining the other end to a sausage filling machine. The pigs belly is then enclosed in a mould and is scalded in the boiler. The pigs belly is finally extracted and treated in the smoking chamber. The sealing plate for the clamping device is made of polyethylene. This saves the manual labour of sewing up the belly ends after stuffing. The new system produces a more regular shape which facilitates the cutting of uniform slices for sale.

Title: Three stream purification of flue gas - using dry wet and by=pass streams in combination according to sulphur content
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/50
Filed: 1980-08-23
Abstract: In the Parent patent (describes a method of flue gas purification in which) 50% of the flow is dry purified after the electrostatic filters and 50% is wet purified; absorption agent is added in excess of the stoichiometric quantity in the dry stage and is utilised in the wet stage. The dry purified is mixed with the wet purified gas to discharge into the chimney at above the dew point of SO2. In this addition, the hot, dry flue gas purification stream is tapped from the boiler at above 350 deg.C, the wet gas purification stream is tapped behind the normal boiler outlet, i.e. behind an air preheater, pref. behind an electrostatic filter; a bypass leads upstream of the inlet to the wet gas purification stream but downstream of the electrostatic filter to conduct untreated gas directly to the gas mixing chamber; here it is mixed with the hot gas from the dry side and the cooler gas from the wet side. Desulphurisation in accordance with modern regulations can be achieved. The tapping of gas to form an additional, third stream as well as the dry and wet purification streams can be varied according to the amount of sulphur to ensure the correct temp. at discharge into the chimney.

Title: Circuit for alarm line monitoring - has square wave generator feeding flat top pulses to alarm installation
Inventor: SCHUBERT PETER
IPC: G08B29/06
Filed: 1980-09-24
Abstract: A square wave generator (3) has its output connected to an impedance (5) consisting of a transformer (6), whose output feeds a two core cable (2). A limiter (7), consisting of a zener diode (8), diode (9) and resistor (10), is connected across the output side of the transformer (6). In its normal state, voltage peaks from the transformer are cut off by means of the limiter (7) so that square pulses appear at the output (2). These pulses are fed to the alarm equipment via a second circuit containing a transformer, and rectified so that comparators (12) in both the above circuits can monitor whether a pre-set voltage valve increases or decreases. When an alarm is set off, the square wave generator shuts down and the comparators, sensing the voltage change, actuate the alarm circuitry. The circuit also covers all eventualities, such as the effects of line tampering, short circuit etc.

Title: Immersed tube tank contents sensor - also measures inclination of vehicle, using additional slip contacts on pivoting float
Inventor: JUNG STEPHAN
IPC: G01F23/68
Filed: 1980-10-09
Abstract: An immersed tube sensor for measuring the contents of a vehicle tank has a mounting flange attached to the tube and a centrally guided float with a slip contact acting in conjunction with a resistance path parallel to the guide rod axis. The sensor also acts as an inclination measurement instrument which occupies little extra space and is simple and very economical to make. For this purpose, the float has a slot parallel to the vehicle longitudinal axis and can pivot w.r.t the guide rod in the plane of the slot. Auxiliary slip contacts on the float act in conjunction with additional resistive paths on the circuit board carrying the level measurement track. The additional paths are connected to an indicator via a differential amplifier.
