Patent DE-4101394-A1 (DE)
Inventor: SCHNELLER MAXIMILIAN
IPC: A61K47/48
Filed: 1991-01-18
Abstract: A process is prepared for coupling carbohydrates or compounds containing a carbohydrate unit to substrates, especially proteins. In this process, use is made in the first stage of a carbohydrate having a free or hemiacetally bonded aldehyde group, or a compound whose carbohydrate unit has such an aldehyde group. This aldehyde group is reductively aminated. Via the amino group thus introduced into the carbohydrate or carbohydrate unit, an organic coupling component bearing a thiol group is bonded so as to form a carbohydrate-coupling component conjugate. The carbohydrate-coupling component conjugate thus formed is coupled in a second stage via the thiol group to a couplable substrate so that the conjugate is covalently bonded to the substrate via a disulphide group or a thioether bridge. The modified substrates of the invention to which a carbohydrate is coupled can be used for immunological purposes, in biochemical analysis and in patho-biochemistry.

The evaluator circuit finally adjusts the oscillator such that the comparator working point is stabilised. USE/ADVANTAGE - Wide band communications, e.g. simultaneous transmission of several TV programmed with p.l.l. continuously holding working point of phase detector constant.
Patent DE-4113148-A1 (DE)
Inventor: ZWEIG KONRAD
IPC: B29C45/14
Filed: 1991-04-23
Abstract: In a method for producing laminated plastic articles consisting of a base layer of thermoplastic material and at least one cover layer 7, flowable thermoplastic material 12 is compression-moulded as base layer between a lower 2 and an upper 5 mould-half with the cover layer laid in between the mould-halves. In order to prevent the mould cavity constantly changing during the compression-moulding of the flowable thermoplastic material or the melt and correspondingly the melt having to change its flow direction again in certain mould sections, which can result in undesired folds and distortions during compression- moulding with the cover layer, it is proposed first to move the mould- halves together as far as their end position, with the interposition of the cover layer and with the inclusion of the mould cavity representing the finished base layer. Subsequently, the compression- moulding operation is carried out in such a manner that a partial piece, representing a displacement body 9, of the lower mould-half 2 is pressed from a lowered position, in which a recess 11 receiving the melt is formed, by means of a lifting piston 10 into an upper position, in which the surface of the displacement body essentially flush with the mould surface of the lower mould-half.

Title: Feed device, esp. for measuring ripple and roughness by the sensing section method - contains guide for surface scanner carriage with displacement detection of sensor tip movable over surface
IPC: G01B7/34
Filed: 1991-10-01
Abstract: A feed device, esp. for measuring ripple and roughness by the sensing section method has a housing contg. a guide arrangement for a surface scanner carriage. The surface scanner can move wrt the carriage on an axis perpendicular to that defined by the guide arrangement. The motion of a sensing tip resting on the surface is converted into displacement-proportional electrical signals as the carriage is driven over the surface. A further mounting arrangement is used to move the surface sensor wrt a further axis at least approximately orthogonal to the first axis. The further axis has an associated drive mechanism. ADVANTAGE - The surface sensor is controlled so as to retain the sensing tip within the sensor's linear measurement stroke without the use of guides.

Title: Sealing ring for printing cylinder shaft - is held clear of shaft when shaft is rotating and is compressed towards shaft using compressed air when printing machine is stopped
Inventor: OTT HELMUT
IPC: F16J15/46
Filed: 1991-10-02
Abstract: The printing plate is clamped by pneumatic devices, and to prevent the escape of air, the shaft (10) is fitted with a sealing ring (18). The sealing ring is made of an elastic material and is so dimensioned that there is a radial clearance between its inner surface and the shaft (10) when the shaft is rotating. When the shaft is stationary compressed air is admitted to the seal chamber (16) and compresses the sealing ring radially inwards and forms a seal with the shaft. USE/ADVANTAGE - The radial clearance eliminates seal friction when the shaft of the printing machine is rotating.
