Patent DE-4003826-A1 (DE)
Inventor: SOUTSCHEK ERWIN DR
IPC: C12N15/09
Filed: 1990-02-08
Abstract: Immunologically active peptides or polypeptides with a partial amino acid sequence of the capside protein VP1 and VP2 of parvovirus B19 are obtained which provide an economical, sensitive and specific test to detect antibodies against the human parvovirus B19. Short peptide sequences are identified which when used as an antigen serve to identify anti-B19 IgG-positive sera. The production of these peptides by gene-technological means is revealed. Other gene-technologically produced antigens which form stably in large quantities in E. Coli and can subsequently be separated from them act as additional antigens for IgG confirmation. Finally a set of antigens facilitates testing for the detection of IgM antibodies against the virus. In addition, the gene-technologically produced components of the surface proteins are substances which may be used for prophylactic immunisation.

Title: Injection moulding - using an evaluation unit to optimise change-over from moulding to the next injection cycle for automation
Inventor: OFFERGELD HEINZ
IPC: B29C45/77
Filed: 1990-04-06
Abstract: To achieve the most effective screw press speed in injection moulding, on switching between the injection and after pressure phases, the sensor signal which measures the acceleration of the screw acting as a piston is fed to an evaluation unit. The unit takes into account the nominal speed value for the screw injection position with the molten material at the end of the injection screw, to minimise the screw run-up for the next injection cycle on switching from injection to after pressure. The acceleration signal is integrated over the time. ADVANTAGE - The technique automates the switching between injection and after pressure, with reduced quality variations.

Title: Frequency synthesis circuit
Inventor: POEZEVARA ALAIN
IPC: H03L7/10
Filed: 1990-04-10
Abstract: The frequency synthesis circuit comprises a phase locked loop (PLL) which has, in succession: a variable oscillator (1); a mixer (2) which receives at its first input the signal produced by this variable oscillator and receives a basic reference frequency (FR4) at its second input; a frequency reducing chain; a phase comparator (6) which receives the signal emitted from this frequency reducing chain and receives a predetermined frequency which indicates the change step (p) by which the output frequency is intended to vary; and a low-pass filter network (8) which emits, at the output, the control voltage for the variable oscillator. According to the invention:   - the frequency reducing chain is essentially formed without any programmable frequency divider and comprises a plurality of frequency changing stages in a cascade circuit between the variable oscillator and the phase comparator, which frequency changing stages each have a heterodyne mixer (20, 20', 20'') which on the one hand receives the signal (FI2, FI3) from the preceding frequency changing stage and on the other hand receives a programmable reference frequency (FR2, FR3) in order to emit, at the output, via a low-pass filter (30, 30', 30'') the signal which is emitted to the subsequent frequency changing stage; - the width of the change of the possible frequencies at the output of the frequency changing stages reduces in the signal flow direction of the frequency reducing chain; and   - the determination of the frequency at the output takes place ...
