Patent DE-4221075-A1 (DE)
Title: Test appts. using continuous movement device for probing PCB - determines electrical characteristics of node located on surface of substrate e.g. printed circuit board
Inventor: MELLITZ RICHARD I
IPC: G01R31/02
Filed: 1992-06-26
Abstract: The permanent movement test system (30) uses a measurement control processor (32), which is connected to other components of the system. An input to the control processor comes from a data bank (34) of the p.c.b. components. This input supplies the node location on the p.c.b. to be tested. The locations are related to the p.c.b. x-y coordinate system. The system (30) has a three-axis movement system (36) and a movement control device (38). The movement system makes it possible for the probe to be positioned on or over the p.c.b. at each point. A position encoder enables the movement control to determine the direction, speed and relative position of each of the associated axes. Movement commands are issued from the control processor to the movement control device. ADVANTAGE - Enables a rapid testing of p.c.b.'s at small distance from structures to be tested.

Title: Washing machine with unperforated drum - retains water within drum during spinning to prevent abrasion damage to laundry and reduce water and energy consumption
Inventor: STOLL MANFRED
IPC: D06F23/02
Filed: 1992-09-01
Abstract: The operate the programs for a washing machine, with an unperforated drum, as the water is heated for the washing cycle, it is taken in batches from the washing drum (1) to be passed continuously to and from the electro-heater (15) to be returned to the drum (1). During the washing and rinsing cycles, all the free water remains in the drum (1). The free water within the drum (1) is spun at intervals during the heating stage in the washing cycle and/or the rinsing cycle, at a set spinning speed. During spinning, and at rest, all the liquid pressed out of the laundry remains in the drum (1). Also claimed is a washing machine with one or more water outlet openings (17) at the washing drum mantle (15) or base (16). They are opened and closed by a control valve (18) with a separate energy source. Pref. during the intermittent spinning actions of the drum (1), all the free water held before acceleration in the recess (9) of the water container (3) or in the heating vessel (14) remains in place and the water pressed out of the laundry during spinning is contained within the drum (1) and while the drum is at rest. USE/ADVANTAGE - The system is for a washing machine, with an unperforated drum, with program cycles for washing, rinsing and spinning. The assembly gives reduced water and energy consumption, without damage to the laundry as there is not dry rubbing against the drum during spinning.

Title: Method for depositing vapour-phase constituents from preferably highly loaded air or technical gases
Inventor: FOERSTER HANS DR
IPC: F25J3/06
Filed: 1993-07-07
Abstract: The method can be used for simultaneous deposition of organic and inorganic vapour-phase constituents from air or technical gases, for example for recovering petrol from displacement air from petrol stations, solvents from air, etc. and for obtaining extremely dry air or technical gases. The object of the invention is to develop a method which allows recovery of all valuable materials (organic condensates and prepared dried air or gas) from highly loaded air, the European Standards for maintaining purity of air in continuous operation being fulfilled with low energy and investment expenditure. The object is achieved by direct condensation in a cold scrubbing system, a circulating flow of the obtained condensate being used as heat-exchange medium in the cold scrubbing, which flow is supercooled in the lower region by a cold-vapour cooling system and, in the upper region, by a cold-air cooling system, the cold content of the pure air being regeneratively used for cooling the heat-transfer medium in the upper column of the cold scrubbing system and for precooling the compressed air in the cold-air cooling system (Figure 1). <IMAGE>
