Title: Controlled dosing of fuel vapour into IC engine - using double action control valve to shut off when engine is off and to restrict fuel vapour release at idling speed
Inventor: HOLCH HANS-WERNER
IPC: F02M25/08
Filed: 1992-02-20
Abstract: Fuel vapour from the fuel tank is collected in an activated carbon filter (10). The vapour is released into the inlet manifold (15) in a controlled manner via a membrane control valve (11). The membrane is operated by the engine suction, via an inlet (B) and shuts off the connection when the engine is stopped. This prevents fuel vapour leaching out via the air filter (14). The control valve has a second valve in line with the main valve. This is pressure controlled, to reduce the flow when the engine is idling, or during engine braking. The second valve has a spring loaded restricted diameter pipepushed into the open position by the spring. USE/ADVANTAGE - All IC engines, prevents fuel vapour loss when parked, prevents overrun on idling.

IPC: B01L3/00
Filed: 1992-02-25
Abstract: With the aid of known measuring vessels, which are used for receiving fluids to be examined, such as blood, blood plasma or the like, the coagulation of blood is determined mechanically. However, a photometric measurement of the coagulation is not possible with these known measuring vessels, which are provided in the centre of the circular base area with a projecting delimiting journal, since for this a complete and uninterrupted passage of the light emerging from a transmitter through the wall of the measuring vessel is indispensable. 
<??>The aim of the invention is to provide a measuring vessel with which both a mechanical and a photometric determination of the coagulation of blood is possible. 
<??>This aim is achieved by virtue of the fact that the measuring vessel (1) has a rectangular shaft (4) whose one end is of funnel-shaped design and opens into the tubular part (7) which has two parallel side surfaces (9), which in each case form a plane contact surface. In this case a foot element is connected to the tubular part (7), onto which foot element the measuring vessel (1) can be placed. 
<??>By means of this design of the measuring vessel it is now possible to carry out photometric analyses over the entire spectral region. However, at the same time the measuring vessel can also be used for examining the blood according to the ball method.

Title: Mixing assembly e.g. cement mixer trough - has hinged safety grid partly covering charge-discharge hole and connected to switch which cuts off power to mixer motor when grid is not fully closed
Inventor: ECKART GERHARD
IPC: B01F15/00

Abstract: In a mixing assembly such as a cement mixer the charge/discharge hole in the mixing trough is partly covered by a hinged grid, and the remainder of the charging hole is covered by a fixed grid. The hinged grid is connected to a switch which cuts off power to the mixer motor when the hinged grid is not fully closed. A suitable cement mixer trough has a charge aperture covered by a two-part grid, one part of which is fixed and the other is hinged. The grid is linked to a switch which interrupts power to the mixer motor when the grid is opened. The cut-off switch is linked to a push mechanism to initiate mixer trough discharge. USE/ADVANTAGE - Prevents injuries to the operator by preventing contact with the moving internal mixer blades. It is suitable for use in particular with cement mixers.

Title: High resolution active and passive opto-electronic display - has movable shutter such that light signals from display elements are transmitted to several thin light conducting fibres
Inventor: FOSS PIERRE NICOLAS DR MED
IPC: G09F9/305
Filed: 1992-06-15
Abstract: The arrangement improves optical resolution of colour pictures produced by computer controlled active and passive optoelectronic displays. A movable shutter (4) with integral lenses (3) is positioned between a display (25) and a light receiving wall (9). The shutter and its lenses focus the light signals of the display elements (1) onto the inlet apertures of thin light conducting cables (8, 10, 11) in the wall. These cables guide their light signals to a light outlet wall (19). This wall has very thin mixed colour light conducting end cables (16, 17, 18). By moving the shutter the light signals of display elements (1) are transmitted to a number of light conductive cables resulting in a saving in space. ADVANTAGE - Provides considerably improved picture resolution. A very compact system.
