Patent DE-3109509-A1 (DE)
Title: Circuit arrangement consisting of a number of CCD elements, particularly for electrical filter circuits
Inventor: KASCHTE WALTER ING GRAD
IPC: H03H15/02
Filed: 1981-03-12
Abstract: In this circuit arrangement, conductor loops of individual CCD elements closed in themselves are provided with input and output lines which are conducted tangentially to circular-arc-shaped sections or parallel to sections of CCD lines extending in a straight line and in which CCD lines to be transferred and/or to be coupled to one another have a predetermined capacitance ratio. It is the object of the invention to specify a circuit lay-out in which the lines can be brought tangentially to the conductor loops closed in themselves. According to the invention, this object is achieved in such a manner that a charge is divided among outputting resonator electrodes (A'1 + A'2) in such a manner that outputting electrode areas (A'1 + A'2) and receiving electrode areas (A1 + A2) have the same area and similar shape and the following relations hold true: A'1/A'2 = A1/A2 and A1 + A2 = A3 = A'1 + A'2; where, as electrode areas: A1 is the output capacitance, A2 are the resonator capacitances, A3 is an aggregate resonator capacitance, A'1 together with A'2 is a coherent resonator and output capacitance area (Fig. 1). A possible application is, for example, CCD filter circuits. <IMAGE>

Title: Propeller for sailing yachts
Inventor: REINBACH MARTIN C F
IPC: B63H3/00
Filed: 1981-03-19
Abstract: A propeller for sailing yachts having a drive shaft journal and propeller blades pivotable about an axis orientated perpendicularly to the drive shaft axis. The technical problem is to design the propeller in such a way that the propeller blades, for moving ahead as well as astern, are automatically put into the operative position under the action of the drive torque and return into a neutral position when there is no drive torque. To solve this problem, the propeller blades are mounted in an outer sleeve surrounding the drive shaft axis. The drive shaft journal has a profiled curve for each propeller blade. Each propeller blade engages by means of a driver in the allocated profiled curve. Each profiled curve has two engagement profiles for shifting the propeller blade into the operative position, one engagement profile respectively being active in one direction of rotation of the drive shaft journal. A resetting device is provided for the propeller blades. The resetting device moves the propeller blades back into a neutral position with as little flow resistance as possible if there is no drive torque. <IMAGE>

Patent DE-3116846-A1 (DE)
Title: Arrangement for protecting a power transistor, which is operating as an amplifier, against overloading
Inventor: HAHN EBERHARD
IPC: H03K17/082
Filed: 1981-04-28
Abstract: In the case of an arrangement for protecting a power transistor (T1), which is operating as an amplifier for unipolar drive pulses, against overloading, both the current flowing through the transistor (as the voltage drop across a resistor which is arranged in its main circuit) and the value of the voltage occurring across the transistor are taken into account as criteria for defining the critical load case. The protection effect is achieved by turning on a protection transistor (T2) which bridges the input circuit of the transistor to be protected, in order to render the signal controlling it ineffective. For each of the said criteria, the instantaneous voltage state to be allocated to it is in each case monitored for exceeding a predetermined limit value in a comparator arrangement (I1, I2) which uses a suitable output signal to characterise this limit being exceeded. In cases in which the comparator arrangements emit an output signal simultaneously, a turn-on signal for the protection transistor (T2) is formed at the start of the output signals which overlap in time, the duration of which turn-on signal is determined by the time interval needed to reach a defined voltage value (Us4), which can be determined using a comparator arrangement (I4) and results from the discharge process (starting from a predetermined voltage value) of a storage element (C). The statement that a predetermined value has been reached is supplied by operational amplifiers which are connected as comparators. <IMAGE>

Title: Process for improving bread cereals
Inventor: BERNASEK GEORG J DR
IPC: A21D2/08
Filed: 1981-08-29
Abstract: Bread cereals are improved by the cereal grains, wetted to 22 % to 25 % moisture content with gibberellic acid- and calcium chloride-containing water, being heated, after a standing time of 7-8 hours at room temperature, to 35 DEG C, this temperature then being kept constant for 6 to 20 hours. During this, the enzyme systems contained in the outer layers are activated stepwise and the undesirable constituents phytin and 5-alkyl-resorcinols are detoxified by their cleavage and chemical conversion. Moreover, the cereal is enriched with protein by the stimulation of amino acid syntheses and, finally, a brief activation of amylases and proteases improves the baking property and, as a result, the digestibility and acceptability of the end products to be produced from the wholemeal.

Title: Chemisorption layer arrangement in safety cabins
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/86
Filed: 1982-01-30
Abstract: The object of the invention is to free the intake air, to be freed from pollutants, first from acidic gases, hydrocarbons and solid dust particles and then to heat said air so that the water vapour pressure of the air above the moisture absorption point of the catalyst bodies provided downstream is sufficient for converting CO into CO2, and then to feed the air to a cooling zone from which it passes to a workplace. According to the invention this is achieved in that the pollutant-laden air having for example SO2, SO3, NO, NO2 and HC-compounds supplied to a filter is first passed through the arranged soda lime layer (2), then through the catalyst layer (for example Hopcalite) (3), then through the soda lime layer (4) and the subsequent activated charcoal layer (5) and, having been heated via a heating layer (5a), is passed to a Hopcalite layer (6) so that, after being passed through a soda lime layer (7), the air is passed to a cooling zone (7a) via which the purified air (8) is then discharged to the safety cabin. <IMAGE>

Patent DE-3211154-A1 (DE)
Inventor: ABENDROTH PAUL ING GRAD
IPC: B41F13/26
Filed: 1982-03-26
Abstract: In a rotary printing machine, an arrangement for mounting an applicator roller and a preceding roller in a fluid feed stream journals the applicator roller and the preceding roller to the printing machine frame with substantial bearing play, and spring loads the applicator roller against the bearing surface away from the plate cylinder. On passing through the cylinder gap the applicator rollers of inking, damping or varnishing units in sheet-fed offset presses are jolted both at the start and end of the gap. The resulting different flattening of the soft applicator rollers causes roller marks, which should be avoided. For this purpose the applicator roller and the preceding roller are braced against each other by springs, so that their bearing play is eliminated and the distance between shafts is constant. This condition is also maintained on passage through the gap. Conveyance of liquid between applicator rollers and the preceding rollers is thus constant.

Title: Method for optical time division multiplex transmission via an optical waveguide of a switching system, in particular a telephone switching system
Inventor: WIEDEBURG KLAUS H DR
IPC: H04Q11/04
Filed: 1982-06-11
Abstract: Method for optical time division multiplex transmission via an optical waveguide of a switching system. A multiplicity of system devices capable of transmission and/or reception are connected to the optical waveguide, between which transmission of control signals, which set system devices, and subscriber information is provided. In the pulse frame defined by frame identification signals, a first block of time slots serves to transmit the control signals and a second block of time slots serves to transmit the subscriber information. Each transmission-capable system device contains a control memory in which memory spaces are allocated individually in each case to one of the time channels of the first block, which memory spaces in turn store whether the allocated time channel is occupied by a system device transmitting a control signal. The transmitting system device selects a free time channel of the first block by means of its control memory and occupies it. The system device designated to receive the subscriber information is then occupied, while the other transmission- capable system devices similarly store the occupancy of this time channel. The frame identification signal (RK1, RK2) in each case contains a short light flash whose intensity is significantly greater than the maximum intensity of the subscriber information and control signals in the first and second block (B1, B2). The light flashes synchronise the addressing of the control memories. <IMAGE>
