Title: Domestic dishwasher detergent feed - has separate and time displaced feeds of different media to the washing water
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: A47L15/44
Filed: 1992-06-16
Abstract: In the detergent feed operation in a domestic dishwasher, for a dosed and program controlled supply of two different cleaning and bleaching materials, they are passed into the washing water separately and at displaced times for mixing with the washing water. The detergent medium is pref. fed during the prerinsing cycle program and at the latest at the start of the next cleaning program cycle where heat is used. The bleaching medium is initially fed during the cleaning program cycle where the temp. of the washing water is 40 deg.C. During the cleaning program cycle, the heating speed and the heating profile of the water is retarded according to the effectiveness of the cleaning media. USE/ADVANTAGE - The operation is for the delivery of an alkali powder or liquid cleaner and an acid rinsing medium into the washing water of the domestic dishwasher. It ensures that the heat results are obtained with a chemical input containing an enzyme medium during the washing program.

Patent DE-4221167-A1 (DE)
Inventor: FERENCZY NIKOLAUS DR ING
IPC: B21C37/06
Filed: 1992-06-27
Abstract: A multilayer pipe, in particular for brake lines of motor vehicles, is proposed, and also a process for producing such pipes. The multilayer pipe is produced from flat steel strip (1) by winding or round deformation and subsequent soldering by means of a solder layer (2) applied to at least one side of the steel strip (1). In order to avoid leaks and later corrosive effects as far as possible during the production of the multilayer pipe, the solder layer (2) consists of a copper alloy having a melting temperature below 1020 DEG C, preferably below 1000 DEG C. In the process for producing the multilayer pipe, the steel strip is, after electrolytic degreasing, first pretreated in a nickel flash bath or in a copper pickle. The steel strip is then coated with the copper alloy which may contain proportions of tin, zinc or silver for reducing the melting point. After the winding or round deformation has been carried out, the multilayer pipe can be coated with an additional corrosion-inhibiting layer. <IMAGE>
Patent DE-4222472-A1 (DE)
Inventor: MAREK JIRI DR ING DR
IPC: G01P15/125
Filed: 1992-07-09
Abstract: The proposal is for an acceleration sensor consisting of an upper plate (1), a central plate (2) and a lower plate (3). The sensor has a movable electrode (4) built out from the central plate (2). The assembly of the plates is simplified by the use of a closed dielectric layer (10) on the upper plate (1) and the lower plate (3) since the plates do not have to be mutually adjusted. The use of stops (17) prevents the jamming of the seismic mass (33) on the upper (1) or lower plate (3). The use of local oxidation (18) reduces the stray capacitance.

Title: Double sided ring spinning frame - has doffing mechanism driven by extending gear driven from a central point
Inventor: MAESER MARTIN
IPC: D01H9/04
Filed: 1992-07-24
Abstract: On a double-sided ring spinning frame which has doffing equipment, the cops are exchanged for tubes by an extending mechanism operating at both sides. The drive is placed between the sides, and pushes or pulls the extending gear. Typically at each side of the spinning frame there is a spindle rail. The cops are doffed by a top bar, which is equipped with grippers to lift the cops, and remove them to a conveyor. The same grippers lift tubes to set on the empty spindles. The top bars have side levers hinged to them, which are held at the bottom with a hinge (9). From the middle of this lever, a short lever extends to a hinge on the base bearing (11, 12). The bar (10) slides through this bearing, and other bearings (14) attached to cross pieces (15) on the frame. ADVANTAGE - The single drive for both sides is economical.
