Patent DE-3311875-A1 (DE)
Inventor: DAISENBERGER GEORG
IPC: H04M3/36
Filed: 1983-03-31
Abstract: For the purpose of averting overloads at control units for groups of subscriber-associated or call-associated switch devices, a counter is incremented with every occupation and deincremented cyclically. The counter emits an overload signal upon the attainment of a limiting value, the overload signal being forwarded to that switch device or being assigned in a memory shared by the switch device to that switch device from which the occupation signal that leads to the immediate attainment of the limiting value in the counter has arrived. The overload signal is formed in the time between occupation and the first selection character, leads to the emission of a corresponding audible character (busy signal) and prevents the acceptance of selection characters. Alternatively, when the counter reaches the limiting value due to an occupation, the information corresponding thereto are still accepted, but a next occupation is not accepted until sufficient time for a corresponding number of deincrementation steps has elapsed.

Title: Device for the subsequent treatment of vessels, such as drinking glasses, tankards and the like serving, in particular, as tableware, after cleaning
Inventor: SCHOELLHORN HUGO
IPC: A47L15/39
Filed: 1983-06-04
Abstract: An equipment housing (1) is closed off at the top by a support plate (2) and a covering plate (3). By means of the switch (4), a fan and a motor can be switched, said motor driving via belts (7, 8) upright inner polishing heads (5, 6) and outer polishing heads (21-26) which are mounted in the support plate (2). The axes of the heads are arranged in a grid system with equal spacings between rows and lines. Each polishing head has a spindle shaft (52) having polishing material which projects approximately radially away from said spindle shaft and having a large area which is accessible from the outside, in particular horse hair, but also fur or fabric strips. A vessel (10) which has previously been cleaned can be placed onto each inner head (5, 6) and easily moved up and down. By means of the outer heads (for example 21-24) it is polished on the outside and subjected to a torque in a clockwise direction and, by means of the inner head (6), it is polished on the inside and subjected to a torque in an anticlockwise direction. During this process, air is blown in from below through a cutout in the plates (2, 3) provided between the inner heads (5, 6) in each case between the inner heads and the outer heads, said air removing the moisture therefrom. Drinking glasses and similar vessels are thus cleaned and polished quickly and inexpensively. <IMAGE>

Title: Process for tinning an extruded aluminium or aluminium-alloy profile
Inventor: SELLNER KURT
IPC: C23C4/08
Filed: 1983-08-03
Abstract: The invention relates to a process for tinning an extruded aluminium or aluminium-alloy profile (6). Aluminium profiles used in electrical equipment must be tinned for the purpose of electrical contacting. It is customary to tin such profiles by electroplating but this is expensive and labour-intensive. A high-strength layer of tin on an extruded aluminium profile is obtained in a simple manner if the tin is applied immediately after emergence of the profile (6) from the extrusion die (5) of the extruding press (1). At this stage of the process, no layer of aluminium oxide, which impedes tinning, has as yet built up on the surface of the profile and, in addition, the heat energy of the profile (6) arising in extrusion is used for the tinning process. <IMAGE>
