Title: Process for preparing chloro-diphenyl phosphane
Inventor: KLEINER HANS-JERG DR
IPC: C07F9/52
Filed: 1983-04-29
Granted: 1985-09-12
Abstract: Chlorodiphenylphosphane is prepared by reacting dichlorophenylphosphane with triphenylphosphane at temperatures between about 300 DEG  and 700 DEG  C. In the temperature range from about 300 DEG  to 500 DEG  C., this reaction is preferably carried out under elevated pressure, in particular under the autogenous pressure which becomes established in a sealed system, while atmospheric pressure is preferably used in the temperature range from about 500 DEG  to 700 DEG  C. The reaction product chlorodiphenylphosphane is in the main an intermediate in various fields, such as, for example, the polymer sector.

Title: Device for scanning a printing plate
Inventor: REHDER JURGEN
IPC: G01B11/28
Filed: 1983-05-07
Granted: 1988-09-15
Abstract: A machine for scanning printing plates to determine the ratio of "printing" to "non-printing" area for pre-adjustment of the ink dosing elements of a printing machine has an array of electronic photo-sensors, each sensor being disposed in a channel having low-reflection chambers which permit sharp delimination of resolution elements on the printing plate and ensure high definition scanning of different types of printing plates under practical conditions. Preferably the diaphragms dividing the channel into chambers have greater spacing at greater distances from the element sensed on the printing plate. To accommodate printing plates of different materials, means are provided for selecting the wave length of the light source. To prevent measurement error due to changes in the distance from the printing plate to the light source and sensor array, the photosensor array is preferably directed or aimed 60 DEG to 45 DEG  with respect to the normal vector of the printing plate, and the light source is in the same quadrant as the photo-sensor array at an angle of 0 DEG  to 45 DEG  with respect to the normal vector. Automatic calibration, automatic printing plate size determination, automatic sensing of identification information engraved on the printing plate, and a stairstep scan to increase the scanning rate are provided by suitable procedures executed by a microcomputer controlling the scanning process and analyzing, adjusting, and interpreting data received from the sensor array.

Title: Adjustable guiding apparatus
Inventor: PFEIL HORST PROF DR ING
IPC: F01D9/02

Granted: 1987-06-25
Abstract: A variable control mechanism for a turbine engine, in particular an exhaust gas turbine of a turbocharger, with a ring of guide blades arranged concentrically around a rotor axle and pivoting around pivot axles between end limits. The pivot axles are arranged in the forward areas associated with the inflow edges of the guide blades; one of the end limits being variable by means of an adjusting ring or the like. Clearance and impact losses are incurred depending on the prevailing setting of the guide blades. The invention provides a guide mechanism which can be constructed inexpensively and which reduces clearance and impact losses. The guide blades are arranged such that they can pivot freely within an angular setting range defined by the end limits. In case of a low load the guide blades pivot freely within the predetermined end limits, and with rising loads they abut against the variable end limit.

Title: Electromagnetically actuable valve
Inventor: BRUNNER RUDOLF
IPC: F16K31/10
Filed: 1984-03-30
Granted: 1989-08-31
Abstract: An electromagnetically operable valve, comprising a coil and an electromagnet containing an armature, the armature of which impinges an actuating member connected to or forming an active member of the valve in operating connection and a lever mechanism arranged between the armature and the valve member for the step-up or step-down transmission of the stroke. In valves of this kind known from prior art a considerable expense in construction is incurred for the accommodation of the lever mechanism which offsets the savings with respect to the costs and the constructive area in long-stroke magnets; this is avoided by a novel construction incorporating the lever mechanism into the electromagnet and between the armature and the actuating member.

Abstract: A method for producing baling wires having enlarged tips for tying bundled items such as reinforcing rods and bags in which enlargements are formed by melting the tips of the wire segments wherein a strip of continuous wire is advanced through a first melting zone in a substantially vertical position, the wire is then heated to its melting point to sever a segment of the wire therefrom causing an enlargement to be formed at the leading tip of the subsequent wire segment, successively heating, melting and severing individual wire segments and causing the formation of the enlargements at the leading edge of the next subsequent wire segment as the strip of wire advances through the first melting zone, successively rotating each individual wire segment at least substantially 180 DEG  so as to again orient each respective wire segment in a substantially vertical position, thereafter advancing each individual wire segment through a second melting zone in its substantially vertical position and heating the opposite trailing edge of each such wire segment to its melting point to form an enlargement thereat. Due to the substantially vertical orientation of the wire segments during the heating and melting processes, it is possible to avoid detachment of the enlargement in a molten condition. Apparatus suitable for practicing the present method is also disclosed.

Abstract: An endoscope sheath having a flexible tube surrounding the elongated core of an endoscope. The flexible tube has a transparent window near its distal end positioned in front of the viewing window of the endoscope. Channels for taking biopsies, injecting air or injecting water to wash the window of the sheath may extend along the endoscope, either inside or outside the sheath. Where the channels are positioned inside the sheath, they may be inserted in a longitudinal groove formed in the endoscope core. The protective sheath may be used with either end-viewing endoscopes or side-viewing endoscopes. In the latter case, the channel for taking biopsies extends through an elongated elastomeric membrane so that a catheter through the biopsy channel may be moved longitudinally by manipulation of an elevator. The protective sheath may be installed by rolling the elastomeric tube into an annular configuration and then unrolling the tube over the core of the endoscope. Alternatively, the tube may be inflated in its unrolled configuration to expand the tube and allow it to be easily slipped onto the endoscope core. A variety of specialized endoscopes may be created by using protective sheaths having a variety of special purpose medical instruments mounted at the end of a biopsy channel and operated through the channel.

Abstract: The fuse employs a fusible conductor wound around the outside of a carrier which surrounds a display device for indicating response of the fuse.  The device has a movable bolt which applies a given pre-tension to a spring via tension wire which ruptures under the applied spring force upon response of the fuse. The spring employs a spring element made of an alloy which exhibits a temp.-dependent shape variation. The expansion of the spring element upon a critical temp. corresponding to an overload below the fuse response level causes the tension wire to be ruptured.
