Title: Method and device in closed heating plants
Inventor: GLOERSEN STIG
IPC: F25B13/00
Filed: 1991-01-08
Granted: 2000-03-21
Abstract: A method of utilizing the high energy values of fossile fuels in central heating boiler systems. Tie boiler system comprises a processor which include an air heat pump (5) whi~~ functions to cool the system flue gases by condensation. A first fan (10) generates a first circulation (C1) of boiler room air, via the air heat pump (5), this circulation of air also passing through a heat exchanger (4) where heat exchange takes place with the flue gases. A second air circulation (C2) is generated with the aid of a flue-gas fan (7) which removes flue gases from the boiler by suction, thereby generating a subpressure in the boiler room so that fresh air will be drawn in from the ambient surroundings, this air passing through the heat exchanger (4). A lower pressure is maintained on that side of the heat exchanger (4) on which the air/flue gas mixture (C2) flows into the heat exchanger, whereas a higher pressure is maintained on the other side of the heat exchanger (4) on which the cooling boiler-room air circulates (C1). This will ensure that flue gases will always flow out to the free atmosphere, via the heat exchanger (4).

Title: Circuit arrangement for controlling the volume range of a voice terminal
Inventor: WALKER MICHAEL
IPC: H04M9/08
Filed: 1992-09-09
Granted: 2001-01-09
Abstract: Described is a circuit arrangement for dynamic control of a voice terminal apparatus which contains a compander function. Instead of analog circuits for dynamic expander and compressor, a digital signal processor (DSP) is employed which, via a prestored characteristic (KL), assigns to individual average level values of the input signal, amplification factors which are fed to the amplifier (VS) located in the send path of the terminal apparatus. The stored characteristic can be shifted or replaced by another characteristic as a function of a noise average value, or from a receive average value obtained from the audible feedback signal. Thus, an amplification change in the send path is compensated in its action upon the audible feedback signal arriving via the receive path.   In a further development, the circuits delivering the level average values are replaced by the digital signal processor, which carries out the functions assigned to these circuits by means of subprograms.

Title: Equipment for manufacturing of subcutaneous capsules
Inventor: HARTZELL ROLF
IPC: A61J3/07
Filed: 1991-03-28
Granted: 1997-03-25
Abstract: The invention relates to an equipment for manufacturing subcutaneous capsules. The cap-sules are produced by cutting from a silicone tube lengths in excess of the final capsule length. The lengths are arranged into rows including a defined number of them and in these rows they are filled and sealed. One end of the capsules is first sealed by glue dosaged into their openings. The material for the capsules is dosaged by an aperture disc glid-able on a plane surface. By sweeping the upper sur-face of the disc the dosage volume is limited to the volume defined by the aperture. To regulate the packaging density of the material vibration may be used during the filling of the apertures. The do-saged material is conveyed to the capsule via a feeder funnel, through which a rotatable spiral spring, functioning as a filling screw, is inserted in-to the capsule to be filled.
