Patent DE-3545274-A1 (DE)
Title: High-precision, self-centring clamping sleeve
Inventor: SPROCCATI OSVALDO
IPC: B23B31/20
Filed: 1985-12-20
Abstract: The self-centring clamping sleeve permits very high precision so that drills, for example, with a diameter of less than 0.3 mm can be clamped with exceptionally small tolerances. This is due to the fact that, in the first place, the centre section (BC) of the tapered outer surface (AD) of the central body (1) of the clamping sleeve or the centre section of the clamping-sleeve holder (7) has a depression so that, when the clamping sleeve is closed, the two complementary surfaces touch one another only at their end sections (AB and CD), and that, in the second place, the ring nut (6) presses against the stop (1'') of the central body (1) of the clamping sleeve only along a circular margin (G) which is arranged close to the axis (EF). <IMAGE>

Patent DE-3615632-A1 (DE)
Title: Device for determining the extent of the dentine body of teeth to be prepared
Inventor: GENTE MICHAEL DR MED
IPC: A61B5/053
Filed: 1986-05-09
Abstract: Preparation of a tooth aims at sufficient removal of substance while saving the vitality of the pulp. In particular, opening of the pulp cavity is to be avoided. At present, there is no clinically usable method for measurement of the distance between the tooth surface and the pulp. The description of the invention presents apparatus that permit reliable determination of the residual dentine thickness left behind during preparation, by measurement of the electrical resistance of the dentine. Unintentional opening of the pulp cavity is avoided. It is possible to differentiate dentine areas with widely open dental canaliculi from sites with obliterated canaliculi. This solution to the problem is based on the finding that the resistance of dentine depends on its thickness and the width of the dental canaliculi and that the dentine conducts the current much better in the direction of the canaliculi than on a path deviating therefrom.
Patent DE-3615973-A1 (DE)
Title: Method for continuously measuring the haemoglobin concentration in an extracorporeal circulation
Inventor: STILLER SIEGFRIED DIPL PHYS
IPC: G01N33/72
Filed: 1986-05-13
Abstract: To measure the haemoglobin concentration, an amount of about 0.1 ml of blood per min is continuously taken under sterile conditions, and without altering the proportionate volume of the erythrocytes, from the extracorporeal circulation. A double peristaltic pump is used to dilute the blood in a fixed ratio. Blood and dilution medium are combined via a specially designed connector in order to avoid sedimentation of the erythrocytes. The erythrocytes are completely haemolysed by the dilution medium (0.5% NH3) and converted into oxyhaemoglobin. The haemolysate is homogenised in a stirred cell using a magnetic stirrer and is then transferred into a microcuvette in a photometer. The oxyhaemoglobin concentration is determined by measuring the extinction at a wavelength of 415 nm (SORET band). The method makes it possible to monitor the blood volume in an existing extracorporeal circulation, e.g. in artificial kidney treatment. It is also possible on the basis of this method to measure the concentration of other constituents of blood continuously over several hours.
Patent DE-3622445-A1 (DE)
Title: Hollow body which is insensitive to pressure surges from the inside
Inventor: SCHUBERT WERNER DR MED
IPC: F16L55/05
Filed: 1986-07-04
Abstract: Conventionally, pressure surges in pipes are absorbed hydraulically, by springs or by viscose. Significantly greater protection against rupture of a boiler wall or of a pipe from the inside is provided by large-area devices inside the pipe/boiler having a plurality of concentric, compressible layers, the outer layer remaining conventionally quite compact. Following on towards the inside from this compact outer layer are a mattress-like layer, which can be repeatedly compressed radially towards the outside, then further inwards a greatly folded internal layer which is likewise placed concentrically around the longitudinal axis of the pipe/boiler, between them a gas-filled chamber which is likewise repeatedly compressible between the solid outer layer of the pipe and the folded internal layer which is also otherwise the termination, and the elastic, interrupted internal layer which is placed further inside than the folded layer, is likewise energy-absorbing, and can consist, for example, of an elastically prestressed wire meshing which thus extends in an undulating manner over its surface and is connected to the inner domes of the folded internal layer of the hollow body which is insensitive to pressure surges from the inside.
Patent DE-3622603-A1 (DE)
Title: Device for processing multicomponent plastics, in particular polyurethane
Inventor: REISINGER GERHARD
IPC: B29B7/76
Filed: 1986-07-05
Abstract: The device for processing multicomponent plastics, in particular polyurethane, consists of a mixing head which is attached to one end of an arm which is pivotable about a vertical axis and is connected via hoses to fixed metering devices for the plastic components. Each hose runs in the plane perpendicular to the pivot axis P in the form of a spiral about the centre of gravity. By this means, during the pivot movement, no torsional forces are exerted on the hose but rather only bending forces occur. A movement through a pivot angle of 360 DEG  is possible. If a plurality of hoses is used, specifically an even number - as is normally the case in practice - the hoses can advantageously be arranged in a counteracting manner, that is to say during a pivot movement, one hose reduces its bending radius whereas the other increases its bending radius. By this means the recovery forces caused by the bending stress virtually cancel each other out and an easy pivot movement of the arm is possible.

Patent DE-3625572-A1 (DE)
Title: Process for obtaining olefins
Inventor: ZIMMERMANN HEINZ DR
IPC: C07C2/20
Filed: 1986-07-29
Abstract: A process is described for obtaining olefins by thermal cleavage of hydrocarbon-containing charges. In this process, some of the products are recirculated to the cleavage process to increase the olefin yield. To increase the yield of propylene and ethylene, other product streams, such as, in particular, butenes, should be treated in such a manner that they can also be recirculated to the cleavage process. To this end, it is proposed to subject butenes formed during the cleavage process to an oligomerisation step using a superacidic catalyst and to recirculate the product to the cleavage process.

Patent DE-3631827-A1 (DE)
Inventor: HEGELER WILHELM
IPC: H03H19/00
Filed: 1986-09-19
Abstract: An active filter with switched capacitors for the traffic broadcast signal of a VHF receiver shows an inverting first amplifier and a second amplifier, an analog shift register with at least two register stages and an adder. The shift register is connected to the output of the inverting first amplifier and the adder adds the output signals from the second amplifier and shift register and sends the summation signal to the first amplifier. The switching frequencies of the capacitors and shift register are rated equal to twice the frequency of the filter input signal multiplied by the number of a register stage in the shift register. In a filter of this type used to filter the MPX signal, the critical capacitive ratios are in the order of 1:1, so that, with high precision, only a small area is required for the manufacture of the capacitors using SC-MOS technology. <IMAGE>
Patent DE-3636140-A1 (DE)
Title: Pressure regulator

Title: Activity sensor
Inventor: NILSSON KENTH DIPL ING
IPC: A61B5/11
Filed: 1986-10-28
Abstract: To obtain a space-saving, robust activity sensor, in particular for controlling the stimulation frequency of a pacemaker having a piezo element, which generates a voltage which is a function of the activity in the region of the sensor, the piezo element (3) is in connection with a hollow space (8), in which there is provided a mass (9) which can move with respect to the said hollow space and with respect to the piezo element. Even in the event of movements parallel to the piezo element, the mass, for example sand, produces a pressure component in the direction of the said element. Apart from physical activities, it is consequently also possible to register pressure surges which act on the hollow space (8). <IMAGE>

Title: Valve-actuating lever made of light metal with a cast-in sliding body made of oxide or nitride ceramic and process for producing it
Inventor: THIEMANN KARL-HEINZ DIPL ING
IPC: C23C4/08
Filed: 1987-10-21
Abstract: What is described is a valve-actuating lever made of light metal with a cast-in sliding body made of oxide or nitride ceramic, in which the sliding body is provided, in the cast-in region, with a layer preventing direct contact between the light metal and sliding body. The sliding layer can consist of a layer of metal or ceramic applied, preferably by flame-spraying, onto the rear side of the sliding block in the region to be cast in, or the sliding block is premounted in a cage made of metal having a closed bottom, the bottom of the cage acting as a contact-preventing layer during the casting-in operation. The layer preventing direct contact avoids too sudden a temperature rise in the sliding piece and reduces the risk that a thermal shock will lead to damage, such as chipping and the like, in the sliding piece.
