Abstract: 21               50,874 ABSTRACT OF THE INVENTION A shift register is utilized to provide a 90° delay in a pulse width modulated current signal, to deter-mine volt-amperes reactive.  The shift register is asso-ciated with a clock that provides a preselected frequency that, in combination with the number of stages in the shift register, delays the pulse width modulated current signal by  an  amount  equivalent  to  one-quarter  period  of  the current waveform in the metered circuit.  After delaying the pulse width modulated signal by 90°, the shifted signal is  multiplied  by  a  voltage  signal  that  represents  the voltage in the metered circuit and the resulting product signal is input to a voltage-to-frequency converter.

Abstract: ABSTRACT: Method of pulse-mode driving of a semi-conductor laser, driving device for a semi-conductor laser and laser-writing apparatus provided with such a driving device.           A semi-conductor laser (60) is driven by first driving the laser in the LED region with a pedestal current pulse from a first current source (41) and by superposing thereon an information current pulse from a second current source (51) after current stabilization. Due to this two-stage drive switching transients can be reduced so that shorter pulses are possible and unnecessary power dissipation between the information pulses is avoided which contributes to the lifetime of the semi-conductor laser.

Title: Thermoplastics/support film stratification - by hot welding
Inventor: ALBERT LUTHER JAMES
IPC: B32B27/00
Filed: 1970-06-17
Abstract: Polyolefin film has a polar and non-polar face. The support is of another material. On their paths they pass through a 1st pressure zone defined by a pressure element and a convex rotary heater. The film is between the support sheet and the heater, which its non-polar face contacts on an arc for rapid heating to a semi-adhesive surface for the non-polar face. They are then passed through a 2nd such zone, with the polar face in intimate contact with the support, for hot-welding and formation of a permanent chemical bond, with adhesion greater than that of the nonpolar face to the heater. Preferably the polar face is produced by an electric discharge.

Abstract: A digital multiplex radio transmission system wherein transmission channels between a fixed radio station and a plurality of mobile radio stations may be established by code division multiplex or frequency division multiplex, individual message channels being separated by means of different distributions of the data symbols transmitted therein. In order to synchronize the fixed station transmitter with the mobile station receivers, respective synchronizing symbols are inserted between the successive data symbols transmitted in any channel. The synchronizing symbols used in all channels are the same, and are spaced at the same time intervals in each channel. Consequently, they are received with significantly higher energy than the data symbols, permitting the multi-path profile to be measured and providing reliable synchronization.

Abstract: Apparatus for denitrifying power station excess gases (crude gas) which come from a flue gas desulphurisation unit and are heated to the requisite catalyst temperature before the injection of ammonia by heat exchange with the denitrified gases (pure gas) and by supplying additional heat. Known denitrification devices fitted with regenerative heat exchangers operate with large gap and leakage losses, which leads to restrictions in the achievable degree of denitrification and hence the efficiency. Moreover, known denitrification devices have a large space requirement, which makes expensive heat insulation measures necessary due to the free surfaces, in order to prevent a deterioration in efficiency due to heat losses. It is proposed to use, for the heat exchange between crude gas and pure gas, a plate heat exchanger (4) which operates in cross-counterflow, the additional heat being supplied and the ammonia being injected (14) to the outlet duct (9) of the plate heat exchanger. At the end of the outlet duct (9) is arranged a deflection hood (16), with the catalysts (9a, 9b) being arranged between its outlet and the re-entry of the denitrified gases into the plate heat exchanger (4). <IMAGE>

Abstract: @ A solid fuel burner 1 has a first chamber 2 for receiving a combustible fuel to be gasified and a substantially conical upwardly directed extraction zone connecting a bottom portion of the primary chamber 2 with a secondary chamber 8 through the apex region 42. The combustible fuel presents a relatively large surface area G into the extraction zone F and relatively low velocity gases can leave the primary combustion chamber 2 to maximise the extraction of gaseous fuel from the fuel while leaving fuel and other particulate material behind. The substantially conical shape of the extraction zone F which provides a convergent gas flow path does however enable a sufficiently high velocity or the hot gas entering into the secondary chamber 8.A transverse entry of cold air H by means of a tuyere assembly 46 is provided at the apex region 42. The high density of the cold air and its transverse flow ensures a good mixing of the cold air with the hot gas before its entry into the secondary chamber 8. The hot gas in the chamber 8 has a circular motion creating a vortex in the centre of the chamber 8. Hot gas leaves the chamber 8 from one side at outlet 9 while cold air flows into the chamber 8 from an opposite side.

Abstract: The invention relates to a method, a device and a method for installing a cable in a tubular cable duct. In the method, the foremost end (3) of the cable (1) in the duct (10) and subsequent portions of the cable are first accelerated in a short time with continuous supply of further portions of cable from a torsion-free store. Then, from the instant a certain speed v is reached, the cable is maintained at a tension such that, at said speed and tension, centrifugal forces in bends and inwardly pulling components of tensioning forces in the cable compensate for one another at the position of said bends, the further portions of the cable being supplied at a supply speed such that the part of the cable already fed into the duct can continue to slide on the basis of its mass moment of inertia. The acceleration can be achieved by causing propelling forces to act on the cable upstream of the inlet end (10a) of the duct in conjunction with pulling forces which act at least on the foremost end (3) of the cable (1) in the duct. The magnitude of at least the propelling forces is controlled by adjusting to zero the net transverse force on the cable, in a bend (8; 51) in the cable located beyond the position where the propelling forces act upon the cable in the direction of movement of the cable. Advantages are that much higher installation speeds and/or greater installation lengths in one go are possible. <IMAGE>
