Title: Test for T:antigens - using a specific antibody from an animal of a different species to that under test
Inventor: GRABAR PIERRE
IPC: G01N33/569
Filed: 1976-03-03
Abstract: T-antigen, esp. cells carrying T-antigen is detected in a biological medium from a living animal, using a specific antibody to the antigens. The antibodies are supplied by an immunoserum from an animal previously given >=1 inoculation(s) with T-antigen supplied by a different species of animal to that supplying the biological medium under test. Variation in the normal level of T-antigen in biological fluids is an indication of rejection of an organ transplant. It also takes part in the prodn. of antibodies. The presence of T-cells or T-antigen is detected rapidly and easily. In an example, a fraction rich in T-antigen was extracted from calf cerebellum. This was injected into ewes and the immunoserum obtd. This was treated with a marker, such as a fluorescent dye and added to human blood under test. After 40 mins. incubation T-cells were made visible under the microscope.

Title: Stop motion for sensing yarn breakages - has tube through which yarn moves and electrode sensing vibration of tube caused by yarn
IPC: D01H4/44
Filed: 1977-06-17
Abstract: A stop motion for detecting the advancement of yarn in a textile machine includes a guide tube through which the yarn in advanced and an electrode which surrounds the guide tube. Vibration of the tube due to the advancing yarn produce fluctuations in a voltage across the electrode and these fluctuations are continuously monitored electronically. If the fluctuations in voltage cease, this indicates that the yarn has broken and the textile machine is shut down. Stop-motion is esp. used with open-end spinning machines using e.g. a spinning rotor. Device is simple and requires no sensor in direct contact with the yarn; thus reducing the risk of damage to the yarn.

Title: Support arm for windscreen wiper blade - has circular opening at its end with deformable flexible end for blade retaining pin
IPC: B60S1/40
Filed: 1977-11-08
Abstract: A windscreen wiper arm (1) is designed to hold a wiper blade. To fix the blade to the arm the arm has at its free end an opening (3) which is virtually circular.
