Patent DE-4237807-A1 (DE)
Inventor: KOCH LUTZ J
IPC: G01N13/02
Filed: 1992-11-05
Abstract: A process for determining at least one foam degradation rating number for foam on a liquid, in particular beer, has the following steps: foaming the liquid, filling a measurement vessel with the foamed liquid, then measuring the amount of liquid formed in the measurement vessel from the foam as a function of time. The measurement values are continuously recorded and/or are recorded at fixed time intervals related to the time elapsed from the beginning of the measure. A time function is approximated on the basis of the series of measurement values and at least one value which characterises said time function is supplied as rating number of the foam degradation. The dependency of said value from the foam degradation is stronger at moments that immediately follow the beginning of the measurement than at moments when the beginning of the measurement lies further back.

Inventor: FENG SHEN
IPC: G11C27/02
Filed: 1992-11-10
Abstract: An FET analog switch has an input node (S), an output node (D) and a terminating element (CL) which is connected to the output node (D). A switching transistor (T1) is connected between the two nodes (S, D). A driver circuit (E1) is used for driving the gate of the switching transistor (T1). In order to reduce the transient error, it is proposed to insert in each case one dummy transistor (T01) between the input node (S) and the source electrode of the switching transistor (T1), and a dummy transistor (T02) between the drain electrode of the switching transistor (T1) and the output node. <IMAGE>

Title: Electro-erosive micro perforation of highly porous filter paper line - carried out so that paper lines are forced to undergo additional electro-erosive micro perforations to increase air and/or water permeability to reach desired value
Inventor: GROSSE WERNER
IPC: D21H25/00
Filed: 1992-12-23
Abstract: The air and/or water permeability increase serves for the compensation of the porosity-fluctuations contained in the basic material. With this compensation, a correction of higher regulation quality is carried out for the desired air and/or water permeability desired value. The correction also results in the line width as well as in its running direction. An optical on-line measuring unit determines the overall porosity, and works back in a closed regulating circuit, as the adjustment value to the microperforation unit. ADVANTAGE - Porosity fluctuations resulting in mfg. are reduced by additional microperforation and on-line measurement so that desired value can be maintained.

IPC: B60H3/02
Filed: 1993-02-11
Abstract: The invention relates to a device for reducing the air humidity in a passenger compartment of a motor vehicle, in particular of a vehicle with internal combustion engine. A heating system is connected to the passenger compartment on the one hand via a discharge duct and on the other hand via a feed duct, an absorbent such as zeolite, silica gel or the like being arranged in the flow path between the discharge duct and feed duct. So that it is possible, over a long period, to prevent the windows of the passenger compartment becoming misted up on the inside using only a small amount of heating power, there is provision for the absorbent to be arranged in a desiccant duct which is connected to the air guide ducts parallel to a duct section of the said air guide ducts via an air flow control element which branches off part of the air stream, it being possible to replace the absorbent located in the flow path of the desiccant duct with regenerated absorbent by means of a replacement device. To be used for drying spaces.

Title: Solar installation for the provision of hot air and hot water
Inventor: GONDOLF FRIEDRICH WILHELM
IPC: F24J2/34
Filed: 1993-03-04
Abstract: The FIGs. 1-3 shown in the drawing 93001 A show a steel trough 1 which has an insulation 2 on all four sides and from below. A glass box 10 is screwed onto the steel trough 1. To avoid condensate and to let exhaust air out of the glass box 10, two regulating flaps 11 are fitted. Mounted in the lower part of the steel trough 1 are sucking-off tubes 3, and via the fan 4 the hot air from the glass box 10, which arises due to insolation, is sucked downwards. Mounted in the steel trough 1 is a pipe coil 7 which is connected at its valves 8 and 9 to a water conduit. At the valve 8 there is an emptying tap. The steel trough 1 is filled up with pebbles 6 or fireclay bricks until above the pipe coil 7. As a result of the suction of the fan 4, warm air from the glass box 10 is caused to flow around the pebbles 6 or fireclay bricks and also the pipe coil 7. As a result, the pebbles/bricks are heated, as is the water, also flowing water, in the pipe coil 7. The hot air is conveyed into the spaces to be heated via the sucking-off tubes 3 by means of the fan 4. The hot air passes out through the air flaps 5 mounted in the spaces. Attached to the air flaps 5 are lamellae which reach into the air flaps 5 upon opening, as a result of which the hot air is directed into the space. The end of the sucking-off tube 3 is connected to a chimney, through the natural suction of the chimney the ... is Original abstract incomplete. <IMAGE>

Title: Motor=driven mechanism to open and close injection mould - moves one supported mould plate by set of spindles whose ends engage nuts turned by endless toothed belt and two-directional motor
Inventor: AOKI HIDEMI
IPC: B22D17/26
Filed: 1993-08-29
Abstract: the motor-driven system for closing and holding an injection mould has one mould plate fixed on a platform and a second mould plate moves on that platform to/from the first plate; a number of tension bars cross the space between the two plates, each bar having one end fixed to the moving mould plate and the other end passing through a hole in the fixed mould plate. The latter in each case is a recirculating ball screw spindle engaging a nut attached to a toothed belt pulley, the end revolving in one of the holes mentioned; an electric motor attached to the fixed mould plate turns the nut; an endless toothed belt passes round the motor pulley and also round other such pulleys which are rigidly fixed to the nuts on the spindles concerned; by this means the arrangement of motor and nuts/spindles moves the one plate to or from the fixed plate according to the direction of revolution of the motor. The example shown has the fixed mould plate (1), whilst the moving plate (3) has two guides (4) for its feet (5). Four tie rods (6) run across the daylight; one end of each rod (6) is fixed to the moving plate (3) and the other end passes through a hole in the fixed plate (1). Each such end (here on the right hand side) is a recirculating ball screw spindle (7). ADVANTAGE - The layout operates the moving mould plate regardless of its weight, and does so with great accuracy. It uses a relatively small motor which need only have a low applied torque and low energy consumption.
