Patent DE-3720783-A1 (DE)
Title: Process for applying a sprayed (gunned) concrete coat
Inventor: HILLEMEIER BERND DR ING
IPC: C04B28/02
Filed: 1987-06-24
Abstract: Process for applying a sprayed (gunned) concrete coat onto a surface. A pumpable and sprayable concrete mixture is made up from cement, aggregates, if appropriate additives, and water. A predetermined volume flow rate of the sprayed concrete mixture is fed, by means of a concrete delivery pump, through a concrete delivery line to a spray unit with propellent-air injection device for propellent air which is under a delivery pressure of several bar. The propellent air is charged with silica dust having an internal surface area of at least 25 m<2>/g. By means of the propellent air, the silica dust is introduced into the volume flow of sprayed concrete mixture in such an amount that the applied sprayed concrete undergoes a spontaneous temperature increase of some degrees Kelvin immediately after application. In combination with this, the silica dust is mixed with a pulverulent polyacrylamide-based adhesive and, if appropriate, additionally with a quick-setting binder and this mixture is introduced with the propellent air into the volume flow of the sprayed concrete mixture. <IMAGE>

Title: Identification system for mobile modules
Inventor: HORSTMANN FRANK-RUEDIGER
IPC: G06K19/06
Filed: 1987-09-04
Abstract: An identification system for modules (M1, M2), which are moved along a transport track (T), has a plurality of reading units (L1, L2) arranged beside the transport track (T), which are connected via a common bus line (B) to a central unit (Z). The reading units (L1, L2) serve to read out magnetic coding devices (C1, C2), of which there is one on each respective module (M1, M2). In each magnetic coding device (C1, C2) there is a plurality of permanent magnets (S1, ..., S4, P) which have their north and south poles differently disposed to form a key code and a magnetic code. Each reading unit contains a number of reading elements which corresponds to the number of permanent magnets per coding device, the reading elements being able to distinguish whether a north pole, a south pole or, indeed, no permanent magnet is present. The arrangement of the reading elements corresponds to the arrangement of the permanent magnets in the coding device. The magnetic code formed by the coding device is then buffered in a store (SP) if, on the one hand, the key code has been recognised and, on the other hand, the magnetic code has been fully detected. <IMAGE>
Patent DE-3731687-A1 (DE)
Inventor: KNOLL ALOIS L DR
IPC: F24D19/10
Filed: 1987-09-21
Abstract: The method has optimised energy supply and energy switch-off and uses a heating characteristic line for controlling predetermined room air temperatures and support temperatures for room air and wall surfaces, as well as a rapid heating-up characteristic line for calculating the latest possible switch-on point for rapid heating up. The heating characteristic line and the rapid heating-up characteristic line are adapted automatically and both in the short term and in the long term to the heating installation, to the building and to the climatic conditions affecting the building. Control and adaptation are carried out using periodic measurements of the heating forward run temperature at the inlet and the heating return run temperature at the outlet of the heating circuit, as well as of the outside temperature. For buildings which consist of only one room, or for heating circuits which have at least one room, the static and dynamic thermal properties of which also apply for all other rooms, the additional use of a sensor for the room air temperature has the advantage of shorter running times of the heating circuit pump during the time when the energy is switched off and the parameters are adapted for the heating characteristic line during control of the fixed room air temperature.

Title: Process and apparatus for the production of a double strand in the tobacco-processing industry
Inventor: SIEMS WOLFGANG DIPL PHYS DR RE
IPC: A24C5/34
Filed: 1988-03-15
Abstract: The simultaneous production of two or more fibre strands in the tobacco-processing industry is to be further improved, so that fibre strands of which the properties are as identical as possible are formed. For this purpose, the excess quantities (44, 44a) removed from the fibre strands (38, 39) are measured. The excess signals related to the two fibre strands are processed in a comparator circuit (56) to form control signals which, via an actuator (57), influence the division of a unitary fibre stream (26) into a plurality of fibre streams (28, 28a) by the adjustment of a separating means (27). By means of a nuclear density-measuring head (61), the density of an encased fibre strand (49) is determined and the two excess-removing devices (42, 43) are controlled synchronously in dependence on the density measurement values obtained. The invention is used particularly in double-strand machines for the simultaneous production of two cigarette strands. <IMAGE>

Title: Automatic locking and release of the latch of a door lock
IPC: E05B55/12
Filed: 1988-03-26
Abstract: The invention relates to a door lock which, when the door is closed and the latch engaged, automatically has the same effect as a door closed by the locking bolt since the latch is locked. This takes place via an additional mechanism which is operated by a bar. When the door is closed this bar remains pressed by the locking plate whilst the latch is engaged in the locking plate. In this position the latch cannot be pressed back. The invention is only advantageous if on one side of the door there is only a knob for pulling shut. In this condition, the lock can be opened normally from the door-handle side or with a key. <IMAGE>

Title: Device for positioning bottles in cleaning machines
Inventor: JENDRICHOWSKI KLAUS
IPC: B08B9/42
Filed: 1988-04-16
Abstract: Bottle cells with centring openings are used for conveying bottles into bottle cleaning machines. Particularly when bottles having clip seals are used it frequently occurs that the bottles, as soon as they have adopted their horizontal position and are moved into an inclined position by further rotation of the bottle cell as the process continues, do not slide into their centring position at the correct time, so that the clip seal situated on the bottle neck may tip too far forwards and therefore partly lock the mouth opening. In order to prevent this undesired premature falling forwards of the clip seal, mechanical adjustment pusher rods are provided which push forward the bottles lying in the approximately horizontally aligned bottle cells. Use of a mechanically operating adjustment pusher rod of this type does, however, make it necessary for the bottle baskets and/or the basket chain in question to be stationary when a bottle is pushed forwards. The object of the invention is therefore to make it unnecessary to have a mechanical positioning device and to ensure perfect positioning of the bottles and/or sealing parts with very simple means even when the bottle cells are circulating continuously.   To achieve this, it is proposed that in the region of the path of motion determined by the bottle cells one and/or more [lacuna] which can be aligned towards the bottle cell and/or the sealing parts of the latter ...

IPC: A41H42/00
Filed: 1988-11-19
Abstract: The invention relates to a workplace module for the hanging production of clothing to set up a transporting system which is closed in itself for the hanging processing of clothing items, in particular in the sewing sectors. It can be used advantageously in industrial tailoring of outer garments. The aim of the invention is to achieve greater technological flexibility of the production units by the design of the transporting system and, at the same time, by lowering the complexity of transport to reduce the throughput times for each individual item and thus the circulating means associated with the transporting. The object of providing a workplace module and a transporting system formed therefrom for the hanging production of clothing, which module consists of a freely selectable tailoring machine and an associated transporting element and can be lined up to form a production unit, the transporting paths being considerably shorter compared to known systems, is achieved in that a tailoring machine is assigned a square transporting loop which surrounds said tailoring machine and consists of four rails. By means of four controllable switches located at the corner points, these rails can be connected to one another and to the rails of the adjacent workplace modules. In this case, both the switches and these rails are simultaneously assigned to all the workplace modules adjoining them. A fifth rail connects two diagonally opposite... Original abstract incomplete.

Title: Method for producing an optical filter for homogenising an inhomogeneously luminescing surface
Inventor: HOSSBACH DIETER DIPL PHYS
IPC: G02B5/20
Filed: 1989-04-01
Abstract: A method, which is relatively easy to implement, is proposed for producing an optical filter, by means of which virtually any inhomogeneously luminescing surface can be homogenised to obtain a luminescing surface of uniform luminance or surface luminosity, e.g. a luminescing surface of an illuminant, a scale illumination such as e.g. a light-guiding plate for illuminating liquid crystal displays, luminescing surfaces in interior lighting systems or in optical imaging systems or the like. In this production method, the luminance which varies over the respective luminescent surface is detected and used for filter production of the optical filter in such a manner that a transparency of the virtually complementary optical filter is produced which varies over the filter surface and corresponds to an inverse imaging of the luminescing surface. This method has the advantage that the entire brightness structure of the respective, inhomogeneously luminescing surface is taken into account and converted into a corresponding transparency structure of the filter, so that the desired homogenisation of the luminance is obtained in the case of a combination of the inhomogeneously luminescing surface with the filter specially produced for this surface.
