Title: Apparatus for distributing fibres uniformly over a conveyor surface
Inventor: MILLER FREDRIC N
IPC: D04H1/72
Filed: 1979-06-06
Granted: 1983-07-07
Abstract: Apparatus for spreading fibres uniformly over a forming conveyor has separate fibre distributors (10, 12), These deposit dry fibres onto a conveyor belt (60) which runs through a tunnel (51) into which fibre-dispensing openings of the distributors (10,12) discharge fibres. 
<??>To reduce the likelihood of fibres accumulating on the tunnel walls (50 etc,) and possibly resulting in lumps falling onto the conveyor belt (60), the tunnel has seals (52, 54) at its belt-entrance and belt-exit ends, and beneath-belt suction produced by a suction box (64) is such that air flow into the tunnel through its sealed ends is insignificant. The distributors (10, 12) are contiguously side-by-side, an arrangement which minimizes the suction requirements.
Patent DE-3061143-D1 (DE)
Title: Method of welding metal pipe sections with explosives
Inventor: LINSE VONNE DUANE
IPC: B23K20/08
Filed: 1980-05-20
Granted: 1982-12-30
Abstract: There is disclosed a method for the explosive welding together of sections of large diameter metal pipe of the kind used in the construction of high volume oil and gas pipelines. In the method, internal and external band charges of welding explosive are simultaneously detonated adjacent to overlapped telescoped pipe ends. The explosive band charges have a tapered or wedged shape in the width cross-section of the band and are placed so that the thicker edge of the band is closed to the narrow diameter of the female flared pipe area and initiation is made along the thicker edge. The velocity of detonation of the initiating explosive is selected so that welding charges are simultaneously detonated around the pipes while maintaining the detonation fronts at superimposed locations and at a large angle to the pipe axis. This avoids unbalancing forces on the pipes and minimizes the collision of circumferential shock waves thus preventing pipe damage and imperfect welds.

Title: Method and an apparatus for controlling a.c. rotating machinery power plants
Inventor: CHECCHETTI MAURIZIO
IPC: H02P9/10
Filed: 1983-08-01
Granted: 1988-02-04
Abstract: The control of a quantity (voltage, phase) relating to a generator-motor pair in an electric power station is accomplished by generating a pulse sequence associated to the quantity to be controlled and a predetermined reference pulse sequence and detecting the relative phase shift. This phase shift, or an integrated value of a number of successive phase shifts, controls a double ramp generator the sign and slope of which are proportional to the detected phase shift. After integrating such signal is employed to vary the magnetic induction of the rotor to balance the system again.

Title: Method and device for controlling the ink supply in an offset printing machine, and offset printing machine provided with such a device
Inventor: OTT HANS
IPC: B41F33/00
Filed: 1984-10-29
Granted: 1987-10-15
Abstract: Printed products and their respective corresponding printing plates are divided into a plurality of image elements. For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic. These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to form a quality measure and to calculate control values for the ink feed devices of the printing machine. In this manner, the use of special color measuring strips may be eliminated.

Patent DE-3483872-D1 (DE)
Inventor: NISHIMOTO NAOMICHI
IPC: H04N9/81
Filed: 1984-10-30
Granted: 1991-02-07
Abstract: In an apparatus for time-compression video recording and time-expansion reproduction, first and second memory address counters are initialized in response to there being a simultaneous presence of vertical and horizontal sync pulses. Until the next vertical blanking period the counters are continuously incremented at different rates during mutually exclusive times for successively writing and reading the luminance component of a composite color television signal. A third memory address counter operable in recyclically variable count modes is provided for writing and reading the color-difference components at sequentially varying rates during a count cycle and generating an output pulse at the end of the count cycle. A phase comparator detects the phase difference between the horizontal sync pulse and the output pulse of the third address counter. A variable frequency oscillator is responsive to the phase difference for incrementing the third address counter at a rate corresponding to the phase difference.
