Title: Combined ventilation and safety device for engine rooms containing ammonia refrigeration units
Inventor: SABATH ULRICH
IPC: F25B49/00
Filed: 1993-03-17
Abstract: Refrigeration units employing ammonia as a refrigerant are surrounded by a gastight casing, on grounds of safety. Between the casing and the ambient air there is an absorption device employing water as the absorbent. The object of the invention is to remove the lost heat of the refrigeration unit by means of ambient air while ensuring the operational safety of the absorption device. In/at the gastight casing an air delivery unit 5 for ambient air is fitted, whose inlet 6 is provided with a check valve (nonreturn valve) 7 and whose outlet is the absorption device 9 which in normal operation is not filled with water. The absorption device 9 is connected, via a line 12 with valve 11, to a water tank 13. The valve 11 is controlled by an ammonia sensor with controller 10 or manually, and is used to fill the absorption device 9 in the case of an accident. The lost heat of ammonia refrigeration units can be removed, during normal operation, from the gastight casing by means of pumped ambient air, the pressure head loss being low. The function of the safety device is retained. <IMAGE>

Title: Device for holding a saw blade
Inventor: HOESCHELE BERND
IPC: B23D51/10

Title: Body for a transport vehicle
Inventor: WELTER HUBERT DIPL ING
IPC: B62D33/08
Filed: 1993-06-28
Abstract: The invention relates to a body for a transport vehicle, it being possible to increase the volume of the body, when the transport vehicle is stationary, by extending the body laterally. The essential feature of the invention consists in the transport vehicle having a two-part body which is designed in one-piece over the entire length in the longitudinal direction and is arranged on transverse struts which are provided perpendicularly with respect to the supporting struts and are supported on the supporting struts, and in that the transverse struts can be extended synchronously in their longitudinal direction in opposite directions, the two-part body spreading out. The advantages obtained with the invention consist in particular in the fact that optimum usage of the transport volume of the body is possible with, at the same time, access to all storage-space positions, and a storage space is produced which can be used in many different ways and, dispensing with logistic designs, allows chaotic storage. In addition, loading and unloading without additional, outer supports is possible when the extended body is at full load-bearing capacity.

Title: Method for simulating the combustion process of combustible material by the underfeed principle on the grate of a combustion plant and combustion furnace for the method
Inventor: SCHUMACHER FRANK
IPC: F23G5/24
Filed: 1993-07-19
Abstract: A method for simulating the combustion process of combustible material on the grate of a combustion plant by burning a sample of the combustible material from above with ignition of the combustion process by radiative transfer of the heat from a combustion chamber located above the sample and simultaneous measurement of its weight change and other combustion parameters. In this method, the sample is brought into a thermally insulated sample space and maintained at room temperature. At the same time, the combustion chamber in a furnace, which combustion chamber is separated from the sample space and closed off from the outside, is heated up to the preset combustion temperature and thereafter opened, and the sample space opened at the top is connected to it from below. A combustion furnace therefor includes in its interior a vertical channel which passes through the upper and lower parts, is surrounded by the thermal insulation and of which the portion in the upper part with the combustion zone is able to be covered from below after moving the lower part away by means of an insulating cover at the line of separation.

Title: Magnetic disc recording and playback of video signals - separates and processes video signal to remove jitter component followed by modification of original signal
Inventor: SATO KOICHI
IPC: H04N5/91
Filed: 1993-09-03
Abstract: The recording and playback system for video signals on a magnetic disc (70) has a processor (200) to provide luminance, colour difference and Y reference signals. The output of the recording circuit (50) is fed to a magnetic head (60). The video input signals (Y+S) are fed to a separating stage (10) that separates the luminance (Y) and synchronising (S) components. The synchronising signal is received by a burst signal generator (20) with the output gated (30) to be added (35) to the original signal. A further signal that is generated (42) is also added in (47). The two components modify the video signal to improve the reproduction quality. USE/ADVANTAGE - Improved video signal quality even with speed fluctuations in recording medium drive.

Title: Method for monitoring the light-off performance of a catalytic converter system in a motor vehicle
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: F01N9/00
Filed: 1993-09-13
Abstract: The invention relates to a method and a device for monitoring the light-off performance of a catalytic converter system (216) in the exhaust port (204) of an internal combustion engine (200). The light-off performance of the catalytic converter system (216) has a great influence on the warm-up emissions of the internal combustion engine (200) and varies as a function of the conversion capacity of that area of the catalytic converter system (216), through which the exhaust gases first flow. The conversion capacity of the said area can be determined from the temperature curve which is obtained when a mixture of air and unburnt fuel is fed to the catalytic converter system. It is important in this that the temperature (TKat) is determined in that area of the catalytic converter system (216) which is crucial to the warm-up emissions.

IPC: G01N27/447
Filed: 1994-03-10
Abstract: A gel electrophoresis tank 14 uses electrodes 16 of carbon fibre tissue material extending across the ends of the gel 18. The tank has optionally removable internal walls (13) for delimiting a gel holding area, in which the gel is cast directly. The electrodes are generally used with buffer solution, and may contact the gel, optionally extending under the ends of the gel as it is cast. With the latter construction, a buffer solution may not be required. A low voltage, e.g. from a dry battery B, suffices for carrying out electrophoresis. The tank is preferably transparent to UV, so that bands in the gel can be visualised using UV without removal. The tank and its contents may then be discarded. <IMAGE>

Title: Hydraulic control of simple tilting cylinder
Inventor: SIEBENLIST WERNER
IPC: B60P1/16
Filed: 1994-04-23
Abstract: The hydraulic system operates a simple tilting cylinder (25,26). In its middle position, the proportional path value (10) provides a connection from the constant pump (29) to the pressure medium supply tank (30). A control signal at the proportional path value switches off when maximum pressure is reached. A control supply line (50) from the inlet control unit (52) to the proportional path value is relieved via a switch-off value (55) when maximum pressure is reached. Maximum pressure is sensed via an electrical pressure switch (56,57) and relayed to the control signal.

Title: Switchable load voltage supply circuit
Inventor: SCHLICHENMAIER ANDREAS DIPL IN
IPC: B60T8/36
Filed: 1994-05-27
Abstract: The circuit arrangement provides supply voltage for switchable loads, particularly for pressure control valves (10) in anti-blocking systems in vehicles. The loads can be connected to earth via a first switch arrangement (12) which is controlled by a control device (15). The latter connects the load to be switched, to the supply voltage via a further switch when the load is to be switched. The appropriate switch processes are carried out with the aid of a  switch lying between the load (10) and earth. This switch is actuated by the control device, particularly the controller of an internal combustion engine. To stop actuation of the control device (15), the switch between the load and earth is opened first, then the switch on the side of the load (10) furthest from earth is opened.
