Title: Hollow drill for removing multi-legged, electronic components which are soldered into printed-circuit boards
Inventor: MAJEWSKI PETER
IPC: H05K3/22
Filed: 1984-04-17
Abstract: According to the methods which were previously known to me for releasing multi-legged, electronic components from printed-circuit boards, this is very expensive, is partially position-dependent or can even be implemented technically only with difficulty. Using the hollow drill invented by me, which encloses the connecting leg and can thus release connections from the printed-circuit board one by one, this problem is solved not only in a manner which is technically correct and is independent of position but which is also still cost-effective in production.

Patent DE-3421669-A1 (DE)
Title: Scraper chain conveyor with intermediate drives
Inventor: KETTERER KLAUS DIPL ING
IPC: B65G19/26
Filed: 1984-06-09
Abstract: Scraper chain conveyors used in underground mineral coal mining can convey larger quantities with the same driving power or can be made smaller but convey the same quantities if intermediate drives are inserted at specific intervals, corresponding to the operating conditions in each case. The same intermediate drives are mounted in or on a guide which is accessible from the goaf side and simultaneously accepts both the forward chain and the reverse chain. The forward chain and the reverse chain are designed with rolling trolleys, which roll on appropriate rails and in so doing considerably reduce the loss due to friction. The carriers are foldably fastened to angular extensions, so that the carrier of the reverse chain can be guided in each case perpendicularly to the conveying run. The ability of such a conveyor to negotiate curves is considerably increased, as the carriers are fastened to only one end of the chain in each case. <IMAGE>

Title: Search register
Inventor: PEREZ ONDIVIELA JOSE LUIS
IPC: B42F21/04
Filed: 1984-06-12
Abstract: A search register is proposed for use on reference works such as dictionaries, in which book pages are provided with index tabs. As an initial guide, a main register is provided which is formed by register tabs which are arranged one below the other over the height of the book in the form of a descending ladder and whose respective height on the ladder indicates a step value. Assigned to each register tab is a group of normal tabs, again in the form of a descending ladder, which form a sub-register. The number of normal tabs in each sub-register corresponds to the step value of each register tab. Furthermore, a method is proposed for arranging the search register, in which a guide rule is used to arrange a tab on each book page, indicating on a scale the steps of the descending ladder and their step value, in order to attach the tabs at the height which is to be determined.

Title: Protective tube for electrical cables
Inventor: GRZEGORS WERNER
IPC: H02G9/06
Filed: 1985-01-17
Abstract: A protective tube (1, 2) for electrical cables which are to be laid in the ground is characterised at its two end regions by mutually complementary recesses (3, 4) and residual walls (5, 6) in the region of these recesses, the surfaces of the residual walls (5, 6) which touch one another when plugged together being provided with surface profiles (9, 10) by means of which a tooth system is produced in the state when the pipes are plugged into one another. The surface profiles are constructed in a triangular manner, seen in a longitudinal section of a protective pipe (1, 2), and are dimensioned in such a manner that it is possible to plug two protective pipes (1, 2) into one another only with elastic deformation of the surface profiles which are otherwise of annular or groove-like construction. In this way, a sealing connection which also absorbs tension forces is created immediately after the pipe ends of the protective pipes (1, 2) have been plugged into one another. <IMAGE>

Title: Electroacoustic arrangement for directionally orientated three-dimensional hearing
Inventor: WOYWOD GERHARD
IPC: H04R5/02
Filed: 1985-04-03
Abstract: In order to enable auditory events to be recorded and reproduced faithfully with regard to stereophony, sound/directional characteristic and locatability from all directions, horizontally and vertically, with the use of only four microphones on the recording side and only four loudspeakers on the reproduction side so that a free choice of the head/body posture relative to the auditory event is guaranteed during reproduction and the listening location can be freely selected on objective or subjective grounds - e.g. more direct or diffuse sound - and in order to manage with four channels and to save further expensive manipulations, four identical transducers - microphones in an analogous manner to loudspeakers - are arranged at the corner points of a tetrahedron. On the recording side, the sound pressure receivers are installed in a sphere of 200 mm diameter - the diaphragms directed outwards and flush with the sphere surface. This arrangement covers the entire recording/reproduction space uniformly in four congruent sections and forms six stereo bases, particularly many phantom sound sources and a high sharpness of localisation. <IMAGE>

Patent DE-3523537-A1 (DE)
Title: Receiver, particularly direction-finding receiver, having a number of channels
Inventor: JONDRAL FRIEDRICH DR RER NAT
IPC: G01S3/74
Filed: 1985-07-02
Abstract: These receiving channels in each case exhibit digital complex selection filters. In each receiving channel, a first computing circuit (FFT), in which the output signals of the selection filters are split into narrow subbands via a fast Fourier transform, is connected following the selection filter. The outputs of the first computing circuits (FFT) are logically combined, on the one hand, with an equal number of inputs of a bearing value computer (bearing angle calculation) and, on the other hand, in each case with the input of a gate circuit (narrow-band gates). The bearing value computer (bearing angle calculation) individually determines the direction of incidence of the received signal in each subband in all receiving channels and combines the subbands having the same direction of incidence to form groups. To represent a selected received signal, the gate circuits (narrow-band gates) are closed for all subbands not falling into the corresponding group. Following the gate circuits (narrow-band gates), second computing circuits (IFFT) are connected for carrying out the inverse fast Fourier transform (Figure 1). <IMAGE>
