Patent DE-3131279-A1 (DE)
Inventor: WILDMANN WOLFGANG
IPC: B65H9/10
Filed: 1981-08-07
Abstract: A device for registering a sheet against a side stop on the feed table of a printing press which includes a suction head flushly recessed in the table and reciprocated for lateral shifting movement, a draft of suction being applied to the head timed with the lateral shifting movement so that the sheet is affirmatively shifted into contact with the side stop. Subsequently, a puff of air is applied to the head timed with the completion of the shifting movement to free the sheet from the head in readiness for removal of the sheet from the table. An auxiliary nozzle recessed in the table in a position adjacent the head is permanently connected to a source of air pressure and arranged approximately parallel to the surface of the table for producing a moving film of air under the sheet in the direction of the side stop to ensure that the sheet remains against the side stop when the suction is no longer effective and until the sheet is removed from the table. The rate of air flow from the auxiliary nozzle and the strength of the puff of air through the head are under the control of respective throttle valves having operating knobs in convenient upwardly facing positions adjacent the suction head.

Title: Tubular packaging container made of flexible material for pourable products
Inventor: GROENER ALOIS
IPC: B65D30/24
Filed: 1981-12-05
Abstract: A tubular packaging container made of flexible material for pourable products has a gathered top end and a tubular piece made of flexible material drawn over it, which together are fixed to the outside circumference of a central insert ring by means of a tape-type attachment member. The tubular insert piece forms a filling valve and, for this purpose, is folded inwards in a region above the insert ring, is guided through the inner axial channel of the insert ring and extends with an end part with a free projection relative to the insert ring into the filling space of the container. Together with reduced manufacturing costs, the filling operation of the container is simplified while, at the same time, the product is protected from moisture penetration by an automatic inner valve closure and product losses are avoided. At least one carrying loop is tied to the tape-type attachment member for handling the packaging container.

Patent DE-3200409-A1 (DE)
Title: Radio controlled analogue clock
Inventor: HILBERG WOLFGANG DR ING
IPC: G04R20/00
Filed: 1982-01-09
Abstract: The arrangement according to the invention serves for displaying radio clock time using mechanical hands, and consists of a combination of an electronic radio clock, electromechanical analogue clock and digital memory with non-volatile storage, in which the clock pulses coming from the electronic radio clock are constrained to be fed, e.g., in a series circuit, both to the memory and to the analogue clock, so that the memory contents always correspond with the hand position. Upon switching on, or after a power failure, the radio clock time no longer corresponds to the time indicated by the analogue clock. According to the invention, the radio clock time is continually compared electronically with the memory time, and as long as the two differ from one another clock pulses of a higher frequency are generated until the radio clock time once again corresponds with the memory time. In this way, the automatically running analogue clock also receives the correct radio clock time after a relatively short correction phase.

Title: Method and apparatus for extracting oil from material containing oil
Inventor: MELNIK GENNADIJ EFIMOVIC
IPC: C11B1/06
Filed: 1982-05-05
Abstract: The method of extracting oil from material containing oil consists in mechanically pressing the material while gradually increasing the pressure. The gradual pressure increase is interrupted at least once by relieving down to a pressure value which results from the condition of unimpeded expansion of the material, after which the gradual pressure increase is continued. The apparatus for carrying out the method contains a press unit (1) which is constructed as a screen chamber (2) with a worm shaft (3) which is arranged in its interior and has a number of worm threads with steadily decreasing pitch of the screw line (5). The worm shaft (3) comprises at least one additional worm thread (6) which lies between the worm threads (4) with steadily decreasing pitch of the screw line (5). The ratio of the size of the pitch of the screw line (9) of the additional worm thread (6) to the size of the pitch of the screw line (10) of the worm thread (4) preceding it is in the range of 17 to 25. <IMAGE>

Title: Method and device for suppressing a negative-sequence system in the output variables of a converter having three-phase current outputs
Inventor: NEUPAUER HELMUT DR
IPC: H02M5/27
Filed: 1982-06-29
Abstract: A negative-sequence coordinate system ( alpha '',  beta ''), which is rotating in the opposite direction, is defined by means of the nominal frequency of a reference variable system (for example orthogonal spatially-fixed components U alpha @ = U0@ cos omega *t, U beta @ = U0@ sin omega *t of a rotating nominal voltage vector). A first vector rotating device (32) transforms the spatially-fixed components of an actual value vector which is formed from the measured values (output voltages U1, U2, U3) into its negative-sequence coordinate system components. A filter (33a) forms the mean values with respect to time as components of the negative-sequence system vector describing the negative-sequence system of the output variables, for which in each case one regulator (33c) has the nominal values zero specified for it. The regulator output variables, as components of a correction vector ( DELTA U*), are transformed back by means of a second vector rotating device (34) into the spatially-fixed reference system and are used for correction of the nominal values or for pilot control. <IMAGE>

Patent DE-3229178-A1 (DE)
Title: Voltage regulator for an AC generator
Inventor: WELTLE PETER
IPC: H02P9/48
Filed: 1982-08-05
Abstract: A voltage regulator for AC generators is proposed which is intended to regulate the AC voltage to a specific root-mean-square value. The root-mean-square value of the voltage is measured by a control circuit and one half cycle of the AC voltage is short-circuited, by means of phase-gating control by a thyristor, as a function of the measured root-mean-square value. In this case, the root-mean-square value should also not be exceeded for small loads or when idling. To this end, a further thyristor (29), which is connected in reverse parallel with respect to the first thyristor (18), is connected with its control connection (29) via a threshold value switch (30) to its anode connection. In consequence, the amplitude of even the other voltage half cycles is limited, particularly when idling. Such a regulator is especially suitable for high-power magnetic generators for supplying the lighting system of motor cycles, but it can also fundamentally be used in short-circuit-proof AC voltage generators. <IMAGE>
Patent DE-3231460-A1 (DE)
Inventor: HAGHIRI-TEHRANI YAHYA
IPC: B42D15/02
Filed: 1982-08-24
Abstract: The multilayer identification card comprises several synthetic layers compounded by the effects of heat and pressure. An inside interface of at least one of these layers exhibits depressions which are filled with the material of the adjacent layer during the laminating process. The adjacent layers are selected in such a way that they are of different transparency. Thus a light and shadow effect is produced in incident light which is reversed in transmitted light.

Patent DE-3233761-A1 (DE)
Title: Method for registering electric signals and/or switching processes and of electric operating variables
Inventor: HOETTEN ARNOLD DIPL ING
IPC: G07C5/08
Filed: 1982-09-11
Abstract: Several methods are known for registering electric signals and/or switching processes of signal systems in mines. Thus, for example, the registration of the signals by means of electromechanically deflected writers or the like on paper, the registration by means of electro-mechanically or electro-statically deflected ink jets on paper or the registration by burning on conductive paper by means of current. For the registration of rapidly changing values it is known to increase the paper advance, to represent the signals by spreading over the entire writing width or to use fast-writing additional devices. The aforementioned methods of registration are found to be partly complex, partly obscure in the arrangement of all relevant data and partly very susceptible to interference. To avoid the aforementioned disadvantages, it is proposed that the electric signals and/or switching processes of the signal systems are entered in the form of digital input signals, and the electric operating variables of the conveyor machine are entered in the form of analog input signals, into a buffer store (5) and are stored in the latter for a particular time, from which the input signals can be output by means of a microprocessor (4) with accurate time-correlation of the individual signals, switching processes and operating sequences to one another via a printer (7). <IMAGE>
Patent DE-3234820-A1 (DE)
Title: Three-position control valve
Inventor: BRUNNER RUDOLF
IPC: F15B13/04
Filed: 1982-09-20
Abstract: The invention relates to a three-position control valve for a hydraulic control device in which the pressurising of at least one consumer line is controlled. Known control valves of this type work according to the principle of a pressure balance. But this requires exceptionally complicated and expensive construction measures. Other, simpler control valves in each case have a passage in the spool for the so-called pressureless flow, although the flow resistance in the neutral position determines the size of the spool. According to the invention, a second flow path is now provided in the spool in addition to the small-diameter first flow path. Like the first flow path, the second flow path is aligned with a housing passage in the neutral position of the spool, but is substantially larger in the cross-section of passage and in the control device lies in a line leading to the return line.

Title: Bypass duct for an exhaust-gas catalyser
Inventor: KELLRINGER PETER
IPC: F01N3/20
Filed: 1983-08-04
Abstract: The bypass duct, invented by me, for an exhaust-gas catalyser is a device which allows the driver to switch off the exhaust-gas catalyser (which will be compulsory in the Federal Republic of Germany from 1986) rapidly and in an effective manner for certain situations, for example in the case of a holiday in another European country where lead-free petrol will not be obtainable and he will thus have to use leaded petrol, which is harmful to exhaust-gas catalysers. As is known, leaded petrol destroys conventional exhaust-gas catalysers within a very short time. Using the bypass duct for the exhaust-gas catalyser, any driver can now help to maintain the effectiveness of his exhaust-gas catalyst in the long term.
