Title: Setting system for spaced loudspeakers - allows individual adjustment of loudspeaker sound levels to obtain required sound centre
Inventor: MITTELSTAEDT MICHAEL
IPC: H04R3/12

Patent DE-4014647-A1 (DE)
Inventor: PLOMER ANTON
IPC: B05C1/08
Filed: 1990-05-08
Abstract: It is provided for a coating station for coating moving webs of material, such as in particular paper or cardboard, has two pressing rollers (1 and 2), one of which, namely the lower roller (1), also serves as counter-roller for the case in which the web of material is being coated by means of a nozzle application unit for coating material with a relatively high application weight of more than 5 g/m<2>. For this purpose, the mutual spacing of the two rollers can be adjusted permanently in the vertical direction. An appropriate guidance of the web partially by means of deflection rollers arranged beneath the operator plane (that is to say in the base), is such that on one side coating is achieved with coating material and on the other side of the web of material a light application of adhesive takes place for reasons of correction of the flat position and in order, on the other hand, to achieve coating (application of adhesive) in a pressing gap between the two rollers. For this purpose, the upper and lower roller - the lower roller additionally - have an application mechanism (6 and 7, respectively) provided with an elastic holder which bears a roller doctor with circumferential grooves and having a sump of application material, specifically on different sides of the two rollers (1, 2).

Title: Digital equaliser with shifters - transmits input as output signal only in specified clock pulse signal flank configuration
Inventor: ISHIKAWA MASAHIRO
IPC: H03K5/1252
Filed: 1990-06-20
Abstract: The shifters respond to an input signal and to at least one clock pulse signal for the input signal transmission as an output signal only, when several clock pulse signal flanks are contained in the same state period of the input signal. The input signal is suppressed as an interference signal only, when specified clock pulse signal flanks are contained in the same state period of the input signal. - To the input and output signal respond setting members for the shifters when the input and output signal levels have a specified signal voltage level.

Patent DE-4022112-A1 (DE)
Inventor: BEBBER HANS JOSEF
IPC: H05H1/26
Filed: 1990-07-11
Abstract: Parasitic arcs occurring in the operation of plasma burners adversely affect economic running and endanger important parts of the burner. Known couter-measures are successful only to a limited extent. Fitting the annular channel between the electrodes and the surrounding nozzle conveying the plasma gas on the inside with an electrically insulating cladding provides only partial protection. Insulating the section of the inner wall of a water-cooled nozzle adjacent the front wall from the outer section is very expensive in construction and insulation. It is therefore proposed to arrange transfer channels (43, 44) uniformly distributed around the periphery between the annular channel (17) for the plasma gas and that (33) between the nozzle end (3) and the burner casing (16) through which part of the plasma gas is diverted and used to cool the end of the nozzle and to force electrically conductive deposits of dusts and the like and back-striking plasma arcs. A sliding flange (29) on this annular channel (33) also counteracts electrical bridge formation from soiling by temperature-caused relative movements.

This opening is formed by omitting two main planks and bridging the gap thus formed by supports (50.2) clamped to the edges of the main planks on each side of the gap. These supports (50.2) are positioned on oppoiste sides of the structural element and support the ends of shorter planks (22.31,22.32,22.41,22.42). USE - Scaffolding with platform built around existing structure.

Title: Film store for photographic processing equipment -  has shaft for film loop, automatic threading, and sensors to detect length of film in each shaft
Inventor: DEUTSCH RAINER DIPL ING
IPC: B65H23/04
Filed: 1990-09-26
Abstract: The film for processing is spliced onto a long length and passed through the various process stages separated by storage shafts (33) which take film loops of programmed lengths. To thread the machine the film transport roller pairs (15,28), each side of the shaft move into a raised position while a shutter (27) closes off the shaft. After threading the film roller pairs direct the film in and out of the shaft, with the shutter removed. Film transport sensors (30,9) control the length of loop in each shaft by measuring the amount of film moved past each process point. The storage loops are programmable for different lengths of film. USE/ADVANTAGE - For setting colour levels in photographic film copier. Automatic film loop control, simple to operate.

Title: Producing plate prosthesis for upper jaw - by placing polymer into mould for producing side of palate joint, buccal fold and jaw crest in one-stage by curing with silicone, then 2nd polymerising
Inventor: ZEISER MANFRED P DR
IPC: A61C13/01
Filed: 1991-08-16
Abstract: The regions at the side of the joint in the palate which cover the palate, extend to the buccal fold and cover the jaw crest are all produced in the first stage of the process. The mould obtd. from the patient is dewaxed and filled with the polymer. A knife is run along the joint in the palate and a narrow part removed up to the papilla incisiva. Silicone is placed in the gap formed and the mould is closed. When cured the mould is opened, the silicone is removed and is replaced with polymer. The plate prosthesis is produced in a second polymerisation in which the second polymer is bonded to that obtd. in the first stage. The silicone used has the advantage that it does not bond to the plaster or to the polymer. ADVANTAGE - The prosthesis fits directly against the mucous membrane of the palate and the adjacent parts of the jaw i.e. with no intermediate gap. Thus when inserted into the mouth there is no dorsal rim gap. The prodn. is simple, quick and cost-saving esp. for silicone material. The method produces stress-free polymer.
