Abstract: ABSTRACT OF THE DISCLOSURE           A windshield repair device comprising a vacuum cup with a built-in piston and cylinder assembly is characterized by a transverse opening in the cylinder so that when the piston is partly withdrawn, gas bubbles can be drawn out of the repair liquid by the vacuum holding the cup in place against the glass.  In operation, after the bubbles are removed from the liquid, the piston is moved toward the glass.  The piston closes off fluid communication through the transverse opening in the cylinder and as it moves further toward the glass. it forces repair liquid into the damaged area.  One end of the cylinder is provided with a sealing ring which bears against the face of the windshield to provide a seal.  The cylinder is used as a reservoir for repair liquid, and allows gas bubbles to be removed from the liquid by the vacuum holding the cup in place . The piston has a pointed projection at its end which bears against a separated cone of glass in the damaged area and breaks the seal between the cylinder and the face of the windshield when pressure in the repair liquid approaches a level such that it is likely to cause permanent damage by delamination of the windshield.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for preventing self-injurious behavior in patients is disclosed.  The apparatus generally contains one or more sensor modules, which detect self-injurious blows, and a separate stimulation module, which produces an aversive electric stimulation.  The sensor module and stimulation module are mounted directly on a patient's body members, e.g., a sensor module can be mounted on a headband worn around the patient's head and the stimulation module can be mounted on an arm band worn around the patient's arm.  The sensor module communicates with the stimulation module by either:  (1) transmitting radio waves, which are received by the stimulation module or (2) sending a small alternating electrical signal through the patient's body, which is detected by electrodes in the stimulation module.  In operation, a sensor module detects a blow to the sensed body member and sends a signal to the stimulation module which in turn generates a controlled electrical current for aversive stimulation.

Abstract: Abstract of Disclosure The invention concerns a sifting procedure intended for treating materials difficult to sift, in which any one component of the material tends to be-come adherent to the surface of the sieve, and a sifting apparatus for ap-plying such a procedure. An example of said materials difficult to sift is the mixture consisting of sunflower seeds and of other kinds of inflorescence material accompanying them, which is produced in connection with harvesting these seeds. The adhesion problem has been solved in the invention by using a brush roll (3) disposed against the surface of the sieve (2), in the manner that the brush roll is rotated about its own axis (4) and, at the same time, the surface of the sieve and the brush roll are displaced in relation to each other. Hereby the brush roll (3) sets the material to be sifted in mo-tion and, on the side, detaches material that has become adherent to the surface so that the sieve is kept permeable. The sieve may consist of a ro-tating drum sieve (2) against the inner surface of which the brush roll (3) is mounted. To the purpose of  moving the material to be sifted, introduced at one end of the drum sieve (2), during the sifting process towards the opposite end of the sieve, the brush roll (3) may be provided with a helical thread (7) moving the material to be sifted.

Abstract: ABSTRACT      A decoder includes an oscillator supplying a decoding signal to the control input of an RF modulator for decoding a sine wave encoded television signal.  The decoding signal developed by the oscillator is randomly phase locked in either of two states with the output of a horizontal sync separator operated in response to the detected output of the RF modulator.  In the first phase locked state, the decoding signal is in antiphase relationship with the encoding modulation resulting in a properly decoded baseband video signal.  In the second phase locked state, the decoding signal is in phase alignment with the encoding modulation so as to constructively combine therewith.  The second phase locked state is detected and broken each time it is assumed allowing the decoder to eventually assume the first phase locked state wherein a properly decoded video signal is produced.
