Title: Parametering system for fault reaction in ind. robot or NC machine tool
Inventor: BAER THOMAS DIPL ING
IPC: B25J9/18

Title: Electrophotographic colour copying process
Inventor: BISAIJI TAKASHI
IPC: G03G15/16
Filed: 1995-09-29
Abstract: The process uses a revolving drum (9) with an integral cleansing system (10). The drum transfers the four different toners, black (14), cyan (15), magenta (16) and yellow (17). Each colour of toner is applied to the drum. The toner is then transferred to the intermediate transfer band (19). Each colour is successively formed on the drum and transferred to the same area of the transfer band to complete the full colour image on the band. The full colour image is then transferred from the band to the paper (24). Each toner has its own density sensor and feed-system.  The paper is carried by means of a take-up roller (25), through registration rollers (26) to the feed-roller (27). A fixing system (28) uses both a heat-roller (28-1) and a pressure roller (28-2) to fix the toner on the paper before it is output (29).

Patent DE-19603319-A1 (DE)
Inventor: POHL FRITZ DIPL PHYS
IPC: H01H1/00
Filed: 1996-01-31
Abstract: In order to establish the residual useful life of earth contacts, it has already been proposed to determine the so-called contact action at the breaker gap as a criterion for replacement in the event of contact erosion and to measure the change in contact action during the switching off stage in order to determine the erosion of the contact tips and convert it into the residual useful life. To that end, with a magnetic drive comprising a yoke, armature and magnet coil, the time taken for the armature to move from the beginning of its movement to the point when the contact starts to open has to be measured. According to the invention, the moment when the armature separates from the yoke of the protective magnetic drive is detected from the voltage at the magnet coil. In this respect, the increase in the magnetic resistance of the magnetic circuit when the armature lifts off is determined. The associated arrangement comprises an evaluation device for determining and displaying the residual useful life, said evaluation device (100) having means (110 - 150) for determining and detecting the voltage at the magnet coil (5).

IPC: D21F1/02
Filed: 1996-06-17
Abstract: The triple-level stock inlet, for a papermaking machine for the prodn. of multi-layered papers, has one separation blade (4) in a rigid structure, with the other separation blade (5) with a pivot (6).  Also claimed is a method to deliver a triple-layered pulp suspension to a fourdrinier where the stock inlet produces three defined and different suspension flows (7-9). The three flows are brought together directly before arrival at the fourdrinier or on reaching the fourdrinier. The flow speeds are set so that the outer layer moves faster than the inner layer.  pref. a fourdrinier moves round a roller to one side of the stock inlet, with the rigid blade (4) next to the roller, or the swing blade (5) is next to the roller. The swing blade (5) is set to give the outer flow suspension layer a higher speed than the inner layer. The flow speed of the centre suspension layer is faster than the inner layer suspension flow, and equals the speed of the suspension flow for the outer layer, or can be slower than the outer layer flow speed. The flow speed for the centre layer can equal the pulp flow speed for the inner layer.

Abstract: In a device for producing sponge iron from lumps of iron oxide in a reduction shaft (1), a hot, dust-containing and carbon monoxide-rich reduction gas is used. The reduction gas is generated in a gas generator by partial oxidation of solid carbon-containing materials and is in part supplied to the reduction shaft through several lateral reduction inlets (3) arranged at the same height around the circumference of the reduction shaft at the lower end of the reduction zone. The lumps of iron oxide are introduced into the reduction shaft through its top area and discharged as sponge iron at its bottom end. Additional reduction gas inlets (15) shaped as downwardly open channels (11) which extend from the outside to the inside of the reduction shaft and/or shaped as ducts which extend obliquely downwards from the outside to the inside of the reduction shaft and have open inner ends are arranged below the plane of the lateral reduction gas inlets. Reduction gas may thus be also supplied to the radial inner area of the reduction shaft, so that the introduction of dust by the reduction gas is not limited to the outer area of the bulk material in the reduction shaft.

Preferably, the target material consists of In, Sn, Pb, Bi, Zn or their alloys.  Also claimed are:  (i) processes for producing and for recycling the above target by melting; and  (ii) an apparatus for carrying out the above processes.

Title: Sieve for sorting out suspended fibres
Inventor: SCHABEL SAMUEL DR
IPC: B07B1/18
Filed: 1996-12-12
Abstract: Sieve in which the gaps between a number of parallel bars (3) provide the sorting function for suspended fibres.  The bars are supported in notches in rings (1). These, in turn, are fixed in carriers (5). The assembly is closed by elements (2). Carriers (5) are considerably more rigid than rings (1), with which they are solidly connected. At least one of the closing elements (2) is connected to carriers (5) by bolts, or other temporary fastenings.  In addition, elements (2) abut against bars (3) via elastic cushions that also act as seals. Bars (3) snap into notches (6) that have a convergent/divergent profile.
