Title: Apparatus to separate metallic bodies from non-metallic comminuted materials
Inventor: RIUS AUTON JUAN JOSE
IPC: B03B9/06
Filed: 1988-09-28
Abstract: The apparatus (e.g. for separating metallic bodies from comminuted glass) comprises a frame (1, 2, 5) supporting a pair of horizontal bars (3, 4) upon which is guided a crosshead (6). The crosshead carries a vertical arm (9) which is vertically displaceable and carries at its lower end a gripper (10). Actuators (11, 12, 13, 14) are provided for moving the gripper (10), the arm (9) and the crosshead (6) and which are controlled by solenoid valves (16, 17, 18, 19), microswitches (20, 23) and timer means. Motion of gripper actuators (11, 12) is initiated via time delay means by a metal detector placed upstream of the apparatus adjacent to a conveyor carrying material beneath the gripper 10. The other actuators are operated in turn via the microswitches, solenoid valves and timer means in order to carry out a gripping cycle. <IMAGE>

Title: FM demodulator
Inventor: SMOLKA PETER
IPC: H03D3/00
Filed: 1988-10-06
Abstract: An f.m demodulator comprises a de-emphasis circuit 10-12 preceding a detection circuit 20. The de-emphasis circuit includes first and second mixers 10-11 connected to a local oscillator 13 and separated by a delay element 12 e.g. an I.F filter. The delay element 12 acts to de-emphasise any pre-emphasis present in the incoming f.m signal. The oscillator 13 is subjected to phase-lock loop control by the demodulated signal and the output of the second mixer 11 feeds a synchronised oscillator 15 which regenerates the de-emphasised f.m signal for detection and other processing. Circuitry including an adder 16 and a delay line 27 modifies the transient response at the input to the oscillator 15. <IMAGE>

Abstract: The machine comprises a pair of dies 13, 15 which can act in mutual cooperation to bend a plate; a manipulator 3 which can grasp and move a workpiece which is to be placed in a scheduled location with respect to the dies and detecting means 19, mounted on the machine in a specified positional relationship with respect to the dies, for detecting a workpiece position provided by the manipulator 3, and means for controlling the manipulator in response to a signal from the detecting means. After calculation of the difference of the actual plate position and the required plate position during manipulation, the plate is positioned in the required position by repeating the action of moving the plate which decreases the difference in a specified ratio. The detecting means 19 are a series of linear transducer sensors and optionally a side sensor at one end of the dies. The manipulator 3 can move parallel to the dies, swing to or from the dies, move up or down and have a multi-pivoting head with movable jaws. …<IMAGE>…

Title: Method and means for decorating a substrate
Inventor: WILSON ROBERT WILLIAM
IPC: B44F1/06
Filed: 1989-10-03
Abstract: A method and means for decorating a substrate such as glass, tiles or mirrors to simulate stained glass comprises taking a flexible, transparent or translucent film, for example a polyester film, which may have a self-adhesive coating on one side, sublimation printing a design (12), a motif or a colouration on the film so as at least partially to penetrate the film, and securing the film adhesively to the substrate. The sublimation printing may be done by a process involving the application of heat and pressure to cause the deep penetration of the printing into the film, in a transfer printing process.

Title: System in vehicle for communicating between data processing stations
Inventor: TAKAI HIDEO
IPC: B60R16/02
Filed: 1989-12-22
Abstract: Successive initializing commands (INIT) are transmitted by a master station (9), constituted by a diagnostic device, to all subordinate electronic control units (1, 3) which are data processing stations, at a predetermined time interval. The number of intitializing commands, INIT, transmitted corresponds to the number of information signals transmitted to a selected control unit after a control command to the selected control unit is executed. For example, in a case where two information signals are transmitted, two successive initializing commands are transmitted to each control unit. In this case, the command code transmitted from the master station (9) prior to the information signals is different from a system call command code even if both of the information signals have the same information as the initializing commands. Therefore, no erroneous response to the information signals by a non-selected control unit occurs.

Title: Reducing mixing of luminance and chrominance signals
Inventor: SONG TONG-ILL
IPC: H04N9/77
Filed: 1990-12-24
Abstract: Luminance and chrominance signals are adaptively filtered 12-14 both spatially and temporally before being combined 3, to reduce cross luminance and cross chrominance while maintaining optimal resolution. The luminance signal Y is passed to a detector 7 in which a pixel is compared with the eight surrounding pixels for detecting edge transitions in the vertical and/or horizontal directions so as to control the selection of an output from each of elements 12-14 which is filtered horizontally, vertically or in both directions. The detector 7 also includes a motion detector which controls the mixing ratio of present and previous frames to provide temporal filtering. The adaptive filtering in the chrominance channels may occur before or after phase quadrature modulation. An encoder comprising a gamma correction matrix 4 and low pass filters 10. 11 is shown, but the adaptive filtering may be applied when decoding. It is possible to dispense with the edge transition detector and retain only the horizontal part of the spatial filtering and the temporal filtering. <IMAGE>

Title: Pulse welding apparatus
Inventor: TABATA YOICHIRO
IPC: B23K9/073
Filed: 1991-03-28
Abstract: A pulse welding apparatus such as a pulse arc welding apparatus or a short-circuiting arc welding apparatus utilizing pulse discharge, wherein there is provided a pulse current waveform control circuit which feeds a desired pulse arc current to the arc welding power source that supplies pulse arc current to the welding load unit, the circuit being so designed as to effect optimum welding without adjusting or changing the circuit components. Even under various welding conditions or environments, furthermore, it is allowed to prevent defective welding during the arc welding caused by the magnetic blow phenomenon and to prevent defective welding such as undercut or sputtering caused by disturbances in the welding torch. The pulse current waveform control circuit is realized as a microcomputerized digital circuit, and the pulse arc current is controlled by the control operation of a program, in order to realize a desired current control by changing the program but without changing the circuit. By utilizing the memory, furthermore, the optimum welding current waveform parameter or a desired arc length signal is learned during the first welding, and the arc length feedback control or the current waveform control is effected during the second welding using a program prepared with the thus learned welding current waveform parameter or the desired arc length signal as a reference. Thus, the molten mass is prevented from being erroneously removed by the magnetic blow phenomenon, and a change in the arc length is suppressed that is caused by disturbance in the welding torch, contributing to improving the welding quality under various welding environments.
