Abstract: PCT No. PCT/FI88/00111 Sec. 371 Date Dec. 20, 1989 Sec. 102(e) Date Dec. 20, 1989 PCT Filed Jul. 7, 1988 PCT Pub. No. WO89/00671 PCT Pub. Date Jan. 26, 1989.The invention concerns a method of constructing a heat exchanger as well as a heat exchanger constructed in accordance with said method. The method comprises piling of essentially similar corrugated thermal transmission plates to cover each other and connecting the spaces between the plates from their edges to inlet and outlet conduits for the mediums participating in thermal transmission so that through every second space between the plates is passed a flow of heat giving medium and through every second space between the plates a flow of heat receiving medium. Essential to the present invention is that the pressure losses of flows and the thermal transmission coefficient of the exchanger are established by piling the thermal transmission plates one over another so that the grooves in different plates are placed at a selected angle with each other. To make this possible the invention uses essentially circular thermal transmission plates or regular polygonal thermal transmission plates in which the direction of the grooves is such that the grooves in plates piled on top of each other may cross selectively at least in two different angles with each other.

Title: Container with superposed drawers
IPC: A47B88/02
Filed: 1989-04-14
Granted: 1992-02-26
Abstract: A container with superposed drawers (12, 14) such as is used as office furniture. The intention, on the one hand, is to provide the possibility to pull out more than one drawer, but on the other hand to prevent the container as a whole from tipping forwards due to the load of the pulled-out drawers. At least one floor roller (16) is arranged on the underside of the bottom drawer (12) near to its front end. Attached to the underside of the "upper" drawer (14) above it are downwardly projecting carriers (46) for the bottom drawer (12), which carriers each bear at their lower end a support roller (44). The support rollers run on the upper edges of the side panels (48) of the bottom drawer (12). When the upper drawer (14) is being pulled out, the bottom drawer is carried along by its carriers (46) and the floor roller (16) supports the front end of the bottom drawer and, via the support roller (44) also the front end of the upper drawer so that the container is prevented from tipping forwards. In order to ensure that the bottom drawer is also carried along by the upper drawer when it is pushed in again, both drawers can be locked together by a latch (32), the latch being ineffective when the drawers (12,14) are pushed in and only becoming effective when the bottom drawer is being pulled out. It is also possible for more than two drawers located above one another to be mutually locked and supported. <IMAGE>

Abstract: Complex waveforms may be transmitted using Lincompex techniques by frequency shifting either the complex waveform, its envelope, or both, in order to ensure that the compressed complex waveform and the envelope signal are transmitted without any substantial overlap therebetween utilizing Lincompex techniques. Overlap between the compressed waveform and envelope prevents the proper demodulation of the complex waveform from the signal transmitted. Accordingly, the frequency shifting techniques utilized in the present application allow Lincompex techniques to be utilized with complex waveforms having both a large bandwidth and a large envelope bandwidth, for example, the waveforms generated by parallel tone or multi-tone digital data.
