Abstract: The present invention relates to an improved machine for shearing and compressing scrap metals, in particular, a large scrap metals, such as an automobile. The machine includes a carriage defined by a pair of spaced apart plates, a rigid base disposed between said spaced apart plates to define a U-shaped cross-section, an arm member having a drive motor operatively connected thereto and a supply table having a drive motor operatively connected thereto. A pivot is provided for pivotally mounting the arm member between the pair of spaced apart plates whereby the arm member pivots toward and away from the base. Another pivot is provided for pivotally mounting the supply table at the end of the carriage whereby the supply table rises in order to supply the scrap metals placed thereon onto the base. The supply table is further provided with a put-out table for serving to exhaust the compact block of scrap metals from the machine with the action of the supply table.

Abstract: Apparatus is provided for preventing the generation of an excessively high voltage by the high voltage circuit of a CRT device, such as a television receiver, thereby avoiding the danger of producing injurious X-ray radiation and further minimizing the potential fire hazard attributed to such an excessively high voltage. A flyback transformer is connected to a resonant capacitor and is driven by a switching device synchronized with horizontal scanning pulses so that flyback pulses are produced during the normal retrace intervals in the horizontal deflection. A relatively low voltage power supply is coupled to the switching device to apply an operating voltage thereto. A first detecting circuit is coupled to the flyback transformer for detecting a high frequency component included in the flyback pulses in the event of a malfunction of the resonant capacitor, such as a disconnection of that capacitor, which high frequency component causes an excessively high voltage to be produced by the high voltage circuit.

Abstract: Apparatus for detecting an error condition in a deflection circuit of a cathode ray tube, the deflection circuit being of the type wherein a periodic retrace signal is generated, including a filter coupled to the retrace signal generator and normally non-responsive to the retrace signal. In the event of an error condition, the retrace signal is provided with higher frequency components which are transmitted by the filter. An output signal generator is coupled to the filter to produce an output signal in response to the signal components transmitted by the filter. In one embodiment, the deflection circuit is the horizontal deflection circuit of a CRT wherein the retrace signal is used to produce the high voltage for the CRT. In this embodiment, the output signal is used to vary the repetition frequency of the horizontal oscillating signal applied to the deflection circuit so as to correspondingly change the amplitude of the retrace signal and, thus, to reduce the magnitude of the high voltage.

Abstract: A data transfer system receives incoming digital data serially at a predetermined bit rate and transfers such data serially at a different bit rate. A distributing device distributes the bits of incoming data into a plurality of groups. A delay device connected to the distributing device delays the bits of each group by predetermined delay times. An assembly device connected to the distributing device and the delay device assembles the delayed bits of each group into a group having a bit rate different from that of the incoming data.

Abstract: In removing nitrogen oxide from a gas containing it, the gas is passed through a region where at least one of calcium sulfate and calcium hydroxide coexists with powerful oxidation agents such as sodium chlorite, potassium permanganate, etc. thereby removing the nitrogen oxide, mainly nitrogen monoxide, from the gas. This method is very effective in purifying exhaust gases resulting from burning operations, since 80 to 90% or more of the nitrogen oxide contained in the exhaust gases is nitrogen monoxide. In addition, this method is also effective in purifying indoor air.

Abstract: A power supply protective circuit that responds to transient overloads, permanent overloads and excessive overloads to protect the power supply and the related switching transistor from damage. The circuit utilizes an astable multi-vibrator which is designed to be pulse modulated by transient overloads. In addition, the multi-vibrator is designed to be turned-off by permanent overloads and by an excessive overload condition. By this arrangement, the multi-vibrator remains in operation for normal transient overloads and does not require resetting manually when such an overload condition occurs.

Abstract: An electromagnet is mounted on a ferromagnetic support member. A ferromagnetic flapper valve element arranged to control fluid flow from a nozzle orifice is movably mounted on the ferromagnetic support member and controllably moved by the electromagnet. The electromagnet, the support member and the valve element form a substantially closed magnetic circuit with an air gap being provided between the electromagnet and the valve element. Ferromagnetic and paramagnetic spacers are disposed between the electromagnet and the support member. The air gap between the electromagnet and the valve element is determined by the combined thickness of the spacers and another gap in the magnetic circuit is determined by the thickness of the paramagnetic spacer.

Abstract: A method of preparing whipping cream comprising the steps of partially removing low molecular weight material from animal milk with a semipermeable membrane or a molecular sieve having capability of screening up to 10,000 molecular weight, to concentrate the non-fat solid content of animal milk to 14.5 to 30 weight percent; homogeneously mixing 50 to 70 parts by weight of the animal milk thus obtained and 50 to 15 parts by weight of an oil or fat; and emulsifying the mixture; and products of such method.
