Title: Hypodermic needle blood taking device - has valves at needle end and at attachable evacuated chamber connection
Inventor: GUERRA LUIS A DR
IPC: A61M5/34
Filed: 1975-09-17
Abstract: The blood-taking device is of the type where a hypodermic needle is inserted into a blood vessela nd one or more evacuated containers in successions are connected to the needle for collecting blood samples. The device has two valves. The first valve closes the proximal end of the needle section when a container is not connected to it and the second valve makes it possible to control the difference of pressure utilized for drawing blood from a subject. The second valve can be closed rapidly in the event it is discovered that the needle lies in tissue exterior to a blood vessel rather than in a blood vessel itself, thereby preventing extravasation and haematoma.

Title: Film strip protection system - uses flexible band on one or both edges of strip to hold individual turns apart
IPC: G03D13/14
Filed: 1976-09-16
Abstract: A flexible band is applied on the edge of the strip before it is rolled up in a reel or a cassette. The band and the strip are both rolled-up together, so that individual turns on the strip are separated from each other. The system may be used for cine films (4a); and it ensures that only a narrow strip along the edge of the film is damaged by contact with the flexible band. The picture areas of the film strip never come in physical contact. The flexible band may have cutouts (9) and may be of sinusoidal shape to increase its flexibility.

Title: Pressurised water reactor shut=down with reduced iodine peak - obtd. by one or more preliminary power reductions
Inventor: SCHUSTER EBERHARD DIPL CHEM DR
IPC: G21C7/00
Filed: 1976-11-10
Abstract: Redn. of I131 peak during shut-down of a pressurised water reactor in which the fuel elements comprise a large number of metal-clad rods and the coolent circuit is equipped with a fission product purificn. plant. Process comprises first reducing reactor power, several days before the planned shutdown, to about 30% for several hours. The power is then raised again to full power until final shutdown. This process may be repeated several times before the final shutdown occurs. Each temporary power redn. results in a temporary iodine peak; the iodine can them be removed from the cooling water by the normal plant during normal running. At the next shutdown or next redn. in power, the iodine peak value is correspondingly reduced. It is thus possible to reduce considerably the peak value finally attained at shutdown and in this way to reduce considerably the time which must elapse before access to the core can be gained.

Title: Frequency interpolation circuit and process - producing low variable frequency by addition or subtraction of pulses and superimposing on standard HF
Inventor: HARZER PETER DIPL ING
IPC: H03L7/23
Filed: 1976-11-25
Abstract: The frequency interpolation circuit is for frequencies determined by coarse setting of an output frequency stabilised by a phase control circuit. It is a multiple of a reference frequency set by a frequency divider. Interpolation is carried out by varying the reference frequency. The reference frequency is generated by superposition of a lower variable frequency on a higher standard frequency. Frequency tuning is achieved by addition and/or subtraction of an adjustable number of pulses to and/or from a fixed frequency. The set frequency can be derived from the standard or be equal to it.
