Title: Inserting ring during surgical procedure -  involves forceps with barrel-shaped jaws which match OD of ring
Inventor: THIEDE ARNULF PROF DR MED
IPC: A61B17/11
Filed: 1990-08-31
Abstract: A Valtrac Ring (RTM) is used to carry out an anastomosis operation on the intestines.  The Valtrac Ring (RTM) can be more easily placed in position by the use of specially designed forceps (1). The forceps have barrel-shaped jaws which match the OD of the Valtrac Ring (RTM) and clamp the bridge of the Valtrac Ring (RTM) forceps and can thus only be sued for the insertion of these rings (RTM).  The plane of the jaws may lie inn the plane of the arms of the forceps or be inclined to the arms. USE/ADVANTAGE - Forceps for inserting Valtrac Rings (RTM) in difficult operations on intestines.

Title: Contactless measuring equipment using laser beam to measure vibrations of object - assigns evaluating unit to receiver modulating frequency shifted reference laser beam by dispersed laser beam from object intercepted by measuring head
Inventor: RUEHL FALK DR
IPC: G01H9/00
Filed: 1991-03-01
Abstract: A beam deflecting section directs the beam from the laser source to various measuring points on the object concerned in sequence. A measuring head receives the light dispersed by the object to supply a receiver. The received laser light modulates a frequency shifted reference laser beam in the receiver. To measure vibrating in three dimensions (x,y,z), three measuring heads (12,13,14) are deployed to intercept radiation originating from a single measuring point (17) on the object (18) concerned. These heads are arranged outside the original laser radiation (16) area in a plane not including the measuring point (17) to supply the receiver. A location determining unit (14') registers the relative position of the measuring point (17) w.r.t. the laser beam (16). USE/ADVANTAGE - Accurately ascertaining rigidity or characteristic shape of osillation of machine construction. Contactless and therefore without inertia. Being three dimensional can ascertain form of measured object.

Title: Exhaust system for four-stroke combustion engine - has two pulsating exhaust gas flows supplied via a common exhaust manifold allowing exhaust gases to leave by a common pipe
Inventor: BREUER HANS-JUERGEN
IPC: F01N3/28
Filed: 1991-05-06
Abstract: In a four-stroke combustion engine exhaust system the engine operates at a pulsating working frequency driven by a number of cylinders each of which has an outlet to a manifold for the pulsating emission of exhaust gases. Two pulsating exhaust gas flows are passed through a catalyst matrix phase shifted against each other from one third to two thirds of the period of the working frequency. Each pulsating exhaust flow is supplied via a manifold merged from groups of two cylinders; and the resulting common exhaust manifolds conjoin the catalytic converter matrix from opposite ends. The treated exhaust gases leave the catalytic matrix by a common exhaust pipe. USE/ADVANTAGE - The arrangement improves the catalytic converter efficiency in cleaning exhaust gases from a four-stroke combustion engine by exploiting the dynamic characteristics of pulsating exhaust gases in driving the catalytic cleaning process. Further, the arrangement exploits the properties of metallic honeycomb catalytic substrate structures.

Title: Coolant circulation safety device for internal combustion engine - prevents overload or overrun by action on fuel injection or ignition timing after failure of pump
Inventor: SEIFFERT ULRICH PROF DR
IPC: F01P5/14
Filed: 1991-05-21
Abstract: Coolant liq. is pumped (6) from the cylinder head (1) via a separator (10) and mixing container (16) to a heat exchanger (8), from which it is recirculated to the cylinder head. The sepd.  vapour is diverted (11, 12) to condensers (13, 14) from which liq.  is drawn by suction (15). In the event of pump failure a signal (17) to a controller (5) retards the ignition (4), or reduces the quantity of fuel injected or the filling of the combustion chambers. ADVANTAGE - Rapid measures to limit engine load and/or speed are implemented independently of thermal inertia in cooling system.
Patent DE-4116840-A1 (DE)
Inventor: FISCHER JOACHIM
IPC: B01D53/54
Filed: 1991-05-23
Abstract: The invention relates to a process for the separation of hydrogen cyanide from gases and exhaust gases by through-flow or circulation scrubbing, formaldehyde being added in a controlled manner to the aqueous scrubbing liquid for glycol nitrile formation; the control is carried out via the measurement of the HCN tension in a branched-off measurement stream, which is first treated with hydrogen peroxide in such a manner that after 1 to 100 seconds free H2O2 is still detectable, and is set to a constant pH prior to the HCN tension measurement. The process avoids a formaldehyde overdose which could not always be avoided in previously known processes having a control of the formaldehyde addition via the measurement of the cyanide-specific redox potential.

The axial groove would then be set behind the stripper edge near the compression chamber. USE/ADVANTAGE - The axial grooves can be provided by laser processing. The oil consumption of the IC engine is improved.
Patent DE-4125288-A1 (DE)
Inventor: KUNKEL HORST
IPC: G01S17/04
Filed: 1991-07-31
Abstract: A circuit arrangement for contactless controlling of a sanitary fitting comprises a transmitter (1) which, controlled by a clock generator (5), emits radiation pulses with the clock frequency of the latter. The radiation reflected by an object (2) in a monitoring area passes to a receiver (3). The output signals of the receiver (3) are counted in a logic control circuit (9). If the number Nz determined during this counting over a certain number N of clock pulses of the clock generator (5) exceeds a number N1 stored in a first memory (10), the logic control circuit (9) generates at an output (A) a signal which opens the solenoid valve (4) of the sanitary fitting. If after generating an output signal at the output A of the logic control circuit during the counting of the output pulses of the receiver (3) over N clock pulses a number Nz is established which is less than a number N2 stored in a second memory (11), the logic control circuit (9) provides at a second output (B) an output signal which re-closes the solenoid valve (4). <IMAGE>
