Title: Process and assembly buffer sharply varying effluent gases in catalytic incinerator
Inventor: MUDERS HERBERT
IPC: F23M20/00
Filed: 1994-01-08
Abstract: In a process to incinerate raw gases in the presence of a catalyst, raw gas is heated in a heat exchanger (1) by clean gas before mixing with a flow portion of the gas (b) heated in a catalytic convertor. The novelty is that the catalytically heated flow portion of raw gas is mixed with that portion of raw gas which has been heated in the heat exchanger.  The catalytically heated portion of the raw gas then flows through a heat storage unit together with the main flow of raw gas. The partial flow is separated from the main flow after the heat storage unit and then flows through a first catalytic convertor, while the main flow is led through a second catalytic convertor for heat exchange with the raw gas.  Appts. for carrying out the process is also claimed.

Title: Generating method for elementary deformable rotationally linked chains
Inventor: CRISAN ADRIANA
IPC: G09B25/02
Filed: 1994-04-09
Abstract: The chains are derived from a platonic body, which in a first phase is divided by cutting planes into an even number of units. These show mirror symmetry congruently and in pairs. In a second phase, the number of units is increased or reduced until it can be fixed at the minimum number which allows a complete upside-down turning motion. In a third phase the units are then closed into a rotationally linked chain which is deformable, and which permits folding around all connecting edges.

Patent DE-4418245-A1 (DE)
Title: Valve gear for an internal combustion engine
Inventor: TENBERGE PETER DR ING
IPC: F02D9/00
Filed: 1994-05-25
Abstract: The invention relates to a valve gear (1) for an internal combustion engine comprising a cam (2) arranged on a camshaft (5) and a cam follower, which is connected to a valve of the internal combustion engine, and a method for the thermochemical heat treatment of the sliding surface of cam (2) and cam follower. The sliding surface of cam (2) and/or cam follower are characterised in that they are provided with a number of minute, randomly arranged recesses in such a way that they have an Sk value < 0. These minute recesses act as oil storage reservoirs and thus promote the formation of a sufficiently thick oil film on the sliding surfaces. In this way metal-to-metal contact is prevented, thereby substantially reducing any wear or abrasion of material on the outer peripheral surface of the cam or the cam follower. <IMAGE>

Title: Four-function electrohydraulic control valve
Inventor: SCHUTTENBERG ECKARD
IPC: F15B13/01
Filed: 1994-05-27
Abstract: The hydraulic valve has a slide which may be set in one of three positions determined by the relative positions of the dual shut-off valve and the solenoid operated pre-control valve. The main valve slide (38) is initially held in a central position by springs (41,42), between hydraulically pressurised cavities (37,39). Attached to the housing is an independently operated electromagnetic dual shut-off valve (11) connected to which is a conventional solenoid valve (10) which may be set in one of four positions by a control (16).  Hydraulic pressure is supplied to both valves through a channel X in the main valve. The various positions of the pre-control valve (10) and the two independent functions of the dual shut-off valve (1) enable the main control valve (12) to provide three separate functions as well as off through outlets (45,47,48).

Inventor: KLOECKING HANS-PETER PROF DR D
IPC: G01N33/50
Filed: 1994-09-10
Abstract: The invention concerns a method of testing the toxicity of materials, in particular synthetic materials, wherein cells are incubated under defined reaction conditions in liquid batches together with the material to be tested. The degree of toxicity of the material can be deduced from the reaction of the cells. The method is characterized in that cells are used whose cell membranes contain arachidonic acid as essential component and in whose membranes [<3>H]arachidonic acid has previously been incorporated. The marked cells are incubated in a test batch in the presence of the material to be tested and in a material-free control batch. The test batch and control batch are adjusted such that they contain the same number of cells and the radioactivity is determined at specific times in the cell-free excess of the batches. Information about the toxicity of the material tested is deduced from the difference between the values measured for the test and control batches.
