Abstract: A method for cryptographic transmission of speech signals and a communication station for performing the method.            ABSTRACT        In a communication system, in which a great number of communication stations operate on the same telecommu-nication channel, such as a radio frequency, secret information transfer for selective calls as well as group calls in secured by cryptographic transmission of speech signals, in which en-ciphering and deciphering of the speech signals in transmitting and receiving stations, respectively, are performed by means of a secret binary transformation code associated selectively with the speech communication in question.  By adding a communication identification signal generated in each participating station as an unambiguous irreversible function of the transformation code to start and stop commands initiating and finalizing, re-spectively, the cryptographic speech transmission from a sending station to one or more receiving stations, as well as to synchronizing signal which may possibly be transmitted during a speech communication and utilizing these communication identification signals as a criterion for initiation and finalization of deciphering of speech signals in the receiving station or stations, a further security is obtained against disturbance or the cryptographic information transfer by third parties through introduction of false messages or commands.

Abstract: ABSTRACT OF THE INVENTION   An improved concave for use on a combine has a plurality of spaced-apart bars mounted parallel to the axis of rotation of the combine cylinder and at an angle with respect to a radial line passing from the center of the cylinder through each of the bars.  The angle of inclination of the bars increases progressively from the intake end to the discharge end of the concave.  The passageway between the concave and the cylinder also becomes progressively smaller from the intake to the discharge end of the concave.  The angle of inclination of the bars aids the passage of grain between the bars and reduces resistence of the bars to the passage of grain therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE     A microwave microstrip/slotline frequency-halving circuit configuration is disclosed in which the frequency division is based on the principle of parametric subharmonic generation.          The circuit comprises a subharmonic resonator formed partially by the overlap of an open-circuited microstrip line on one side of a dielectric substrate and a short-circuited slotline in the ground-plane on the other side of the substrate.  The resonator is completed by a pair of varactor diodes symmetrically placed in holes in the dielectric substrate so as to form connections between the end of the microstrip line and the two sides of the slotline below.  An input signal at frequency 2f entering via the microstrip line results in the propagation of a signal at frequency f in the output slotline.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to various actuating drive mechanisms of a rotary printing press which use an electric motor to cause rotation of a shaft - the torque or torque dependant variable of the motor is measured and compared with a predetermined standard.  A certain threshold deviation from the standard is then used as the criteron for correction.  The standard is the torque or torque dependant variable which occurs when the motor is driven in a constant direction during the adjustment of the actuating drive.  This type of control allows play in the gears or idle movement of the motor to be suitably compensated for.

Abstract: COCCIDIOSIS VACCINE            ABSTRACT OF THE DISCLOSURE         Sporozoites of coccidia fail to develop in chickens which are immune and many are blocked from penetrating host cells.  Although previous attempts to immunize chickens with non-viable coccidial antigens have been unsuccessful it has been discovered that extracts from sporozoites or sporulated oocysts of E. tenella induce high levels of protective immunity.  These extracts contain at least 15 polypeptides many of which are associated with the surface of the sporozoite and induce good immune responses.  Antibody to these polypeptides blocks sporozoite-host cell penetration in vitro and neutralizes sporozoites in vivo.  One or more of these polypeptides may be used as an antigen to protect against coccidiosis.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method and a device for scrap preheating by means of hot gases, preferably steel furnace exhaust gases.  The preheating is accomplished in a preheating chamber (1) for a scrap bucket (2) having bottom structure permitting passage of gaseous medium there through and a level seating surface (24) at its top edge.  The chamber is closed by a cover (3) including an inner hood (28), a depending outer cover plate (36) and a partition wall (42) projecting downwardly between the hood and the plate.  The cover engages the chamber with an exterior sealing at the water seal (16,38), a first seat (50) at the hood (28) and a second seat (44) at the partition wall (42) against the seating surface (24) of the scrap bucket (2).  The seats delimit an inlet space (A) above a scrap charge (Q), an outlet space (B) outside the scrap bucket (2) and an intermediate annular space (C).  The intermediate space is provided with an inlet pipe (54) for a purging medium with a flow control damper (56).  The damper is monitored by a pressure regulating device (74), which is connected to a pressure sensing means (66 and 68) below the hood (28) and in the intermediate space (C) respectively.    In operation hot gases flow through the scrap charge (Q).  There is then a higher absolute pressure in the inlet space (A) than in the outlet space (B).  In order to prevent preheating gases from passing through the first seat (50) and consequently bypassing the scrap charge (Q) without giving off their heat content, purging medium is supplied to the intermediate space (C).        By means of the damper (56) and the regulating device (74) the pressure is adjusted in the intermediate space (C), in order to make it not substantially less than the pressure in the inlet space (A).  Consequently, virtually no leakage between from inlet space (A) into the intermediate space (C) takes place.  All leakage consists of purging medium, which leaks out to the outlet space (B) past the second seat (44).  According to a particularly preferred embodiment in the inlet pipe for purging medium is connected to the outlet space (B) and includes a fan (60) for pressure elevation, and consequently, a closed circuit is obtained (Figure 2).

Abstract: ABSTRACT    A data communication sustem (Figure 1) is described that covers a geographic area divided into a plurality of non-overlapping zones (Figure 2) and includes a general communications controller (GCC, 104), a plurality of channel communications modules (CCM 106, 108, 110, 112) and associated transmitters (114, 120, 124) and receivers (116, 118, 122, 126, 128), and a plurality of portable radios (130, 132, 134).  Message signals carrying alphanumeric information are communication between the GCC (104) and the portable radios (130, 132, 134) by way of a radio channel.  Each CCM (106, 108, 110, 112) takes a signal strength measurement every time it receives a message signal from a portable radio (130, 132, or 134). The GCC (104) gathers the signal strength measurements from the CCM receivers (116, 118, 122, 126, 128) receiving the same message signal and computers an adjusted signal strength for each zone.  The GCC (104) then selects the zone having the largest adjusted signal strength for determining the location of the portable radio (130, 132 or 134) that transmitted the message signal.  Whenever the GCC (104) transmits a message signal to a portable radio, the CCM transmitter (114, 120, 124) is used that covers the zone having the largest adjusted signal strength for the last transmission from that portable radio (130, 132, 134).  Since the GCC (104). can be simultaneously transmitting message signals to portable radios (130, 132, 134) in other zones using non-interfering CCM transmitters (114, 120, 124), information throughput is greatly enhanced.

Abstract: POSITION RESPONSIVE APPARATUS SYSTEM AND METHOD       HAVING ELECTROGRAPH APPLICATION     ABSTRACT OF THE DISCLOSURE     A position responsive apparatus system and method which employs a position responsive surface formed of two orthogonally disposed arrays of grid elements which in one embodiment, the elements are coupled along one border with a resistor chain or the equivalent which is excited with an a.c. source at terminal locations. Capacitive coupling between the orthogonally disposed arrays at the cross-over locations of grid elements is significantly reduced by reducing the area of the grid elements at the cross-over positions. Further, intermediate grounding terminals serve to minimize disruptive potentials caused by the capacitive coupling. The control for the system employs a procedure wherein a correction look-up table is developed as part of the manufacture of the apparatus wherein readings are taken at the nodal points of communication between the grid array and the resistor chain and which then are treated to provide a regularly incremented sequence of address values developed from a signal domain computation.          Physical domain coordinate values are correspondingly derived and are located in the table with each address value. The control for the embodiment accesses this memory for purpose of developing corrected coordinate outputs, thus eliminating the need for precise calibration of each resistor within the resistor chain The invention further contemplates the employment of transparent grid array elements. Significant improvements to performance are achieved by exciting these elements from resistor chains located and coupled therewith at oppositely disposed ends of the grid elements. An improved switching approach is provided wherein excitation currents are employed at the switching stage which then are applied to voltage follower stages for coupling with the grid array terminal.
