Abstract: PHN.9697                                    28.8.80 "ABSTRACT": "A direction- and frequency-independent loudspeaker- or microphone column or a loudspeaker- or microphone surface".            An arrangement for receiving or reproducing sound waves, comprises five, seven or nine transducers situated in line at equal distances from each other (such as for example 1 to 5), all transducers each being connected to the same transmission channel via an individual amplitude control device (11 to 15). The amplitude control devices are adjusted so that the ratios between the conversion factors of the combinations of a transducer and an associated amplitude control device, viewed from the one end of the arrangement to the other end, are 1 : 2n : 2n2  : -2n : 1 in the case of five transducers, 1 : 2n : 2n2  : n3 - n : -2n2  : 2n : -1 in the case of seven transducers, and 1 : 2n : 2n2  : n3 - n : ?(n4  - 1) - 2n2  : -(n3 - n) : 2n2 : -2n : 1 in the case of nine transducers. This results in an output signal of the arrangement which is substantially independent of direction and/or frequency. Moreover, the arrangement may be realized in a very simple manner. The invention also relates to a combination of five, seven or nine arrangements as described in the foregoing (for example 41 to 45), which are situated adjacent each other or in line at equal distances from each other. The arrangements each comprise a further amplitude control device, which devices are all connected to a transmission channel of the combination.          The amplitude control devices are adjusted so that the ratios between the conversion factors of the arrangements, viewed from the one end of the combination to the other end, are 1 : 2m : 2m2  : ?2m : 1 in the case of five arrangements, 1 : 2m : 2m2  : m3 -m : -2m2  : 2m : -1 in the case of seven arrangements, and 1 : 2m : 2m2  : m3 -m:          : ?(m4  - 1) - 2m2  : -(m3 - m) : 2m2  : -2m : 1 in the case of nine arrangements.

Abstract: Abstract A highly accurate current mirror for IC implementation is comprised of low beta transistors and operates on a low supply voltage by utilizing a bias network with a balance sensing feedback network to control the bias voltage.  The output current of one of the mirror transistors is compared with the reference current and the level of the current is then forced to equal the reference by means of the bias voltage adjustment.

Abstract: ABSTRACT OF THE DISCLOSURE           In this apparatus for dynamically translating virtual memory addresses to real memory addresses) a master system page table maintained in a memory associates real memory addresses with their corresponding system virtual memory addresses.  This table is organized with each virtual memory address stored in it at an index location which is a smaller value formed as a predetermined function of the virtual memory address value.  The translator forms the index from the virtual memory address according to the function, enters the table with it, and extracts the corresponding real memory address.  In a preferred embodiment, every process (i.e., job) may reference any address in any segment of a process virtual address space, and a dedicated mechanism converts such a process virtual address reference to a system virtual memory address, which then is converted to the real memory address.

Abstract: ABSTRACT         A glass fibre for optical communication is formed by a vapour deposition process on the inside surface of pure silica substrate tube.  The substrate forms the outer cladding whilst the inner and core are formed by the deposited layers.  An intermediate layer of the cladding has a refractive-index similar to pure silica but due to compensating dopants.  Thus deposition and sintering temperature is reduced.  The inner layer of the cladding is however undoped pure silica, thus reducing absorbtion losses in this important region.         A step in a process for making optical fibres comprising collapsing a tubular substrate to provide a preform is carried out in a stream of pure chlorine vapour acting as a drying agent.

Abstract: ABSTRACT            Method and arrangement for controlling the print current in metal paperprinters For record carriers with a greatly varying thickness of the metal layer, the burn out process is effected dynamically with respect to the current strength.  During the starting phase up to the beginning of the actual arcing phase a relatively high current is applied which is sufficient to burn out even thick metal layers.  As burning out proceeds, the print current, after a particular arc voltage has been reached, is reduced in a short time, maintaining the are and avoiding an undesirable burning out which would increase the print spot.  For thinner metal layers the burn out current is correspondingly lower.  The maximum burn out current is automatically adjusted to the thickness of the metal layer by measuring the arc voltage between electrode and metal surface of the record carrier.   Suitable arrangements for controlling the burn out current are character-ized by an (are) voltage-controlled current control circuit.

Abstract: A B S T R A C T     This invention discloses a modular infrared heating device having an outer casing which encloses a heating chamber wherein one or more infrared lamps are vertically positioned.    The heating device also includes an intake channel which communicates with an opening in the outer casing and with the heating chamber.  At least one heat exchanging plate is positioned within the heating chamber adjacent to the infrared lamps such that it is capable of being heated thereby.  The plate forms the lower boundary of an air discharge channel through which heated air passes.  This plate has a plurality of open-ended tubular conduits mounted onto it.  Each of these conduits is constructed to have a hollow inner channel and is mounted onto the heat exchanging plate such that its hollow inner channel is aligned with a corresponding opening in the plate.  The conduits extend into the discharge channel transversely of the direction of flow therein and are curved to present end portions extending parallel to the direction of flow in the discharge channel to induce air flow through the conduits.  The heating device is also equipped with a fan which facilitates the circulation of air through the heater.  Air moving through the heater passes over the infrared lamps, over both side of the heat exchanging plates, and through and around the tubular conduits such that it is capable of absorbing heat from these components of the device.

Abstract: ABSTRACT OF THE DISCLOSURE In the direct measurement of thermal energy transferred in heating or air conditioning installations, a reference voltage is generated across a capacitance connected to one input of an integrating circuit by feedback from the output of the integrating circuit when the voltage across the temperature sensor in one of the outflow or return lines is applied to the other input of the integrator circuit.  First and second timing periods initiated by impulses from a volume flow sensor cause successive application of voltages from the other temperature sensor and a constant current source to the other input of the integrator circuit whereupon the integrator circuit charges an integrating capacitance in accordance with a difference between the voltages produced by the temperature sensors during the first timing interval and discharges the integrating capacitance at a constant rate during the second timing interval.  A gate is enabled during the second interval to pass clock pulses proportional to the charge on the integrating capacitance.  During the first and second timing intervals, a switch in the feedback circuit for the reference capacitance is open.
