Title: Medical monitoring sensor for bleeding under bandage - responds to change in bandaging material i.e. dampness and/or colour to release alarm via evaluating circuit
Inventor: STAEBLEIN ALEXANDER
IPC: G01N21/84
Filed: 1990-05-07
Abstract: The sensor can be wound into the bandaging. A lead connection (42) conveys at least one signal dependent on the presence of blood to the outside as well as supplying power to the sensor arrangement (40). An evaluating circuit derives: an alarm signal from the measured value(s) in case of bleeding. The sensor (20) can be a moisture responsive type or an optical type responding to change of colour. The optical sensor can be additional to the dampness type. The latter can be based on change of electrical conductivity of the bandaging material and comprise two conductor paths (22,24) mounted on insulating, chemically inert surface, e.g. of plastics material. ADVANTAGE - Reliably self operating response to start of low blood loss, alerting medical personnel and avoiding need for more serious medical intervention arising from neglect.

Patent DE-4037514-A1 (DE)
Inventor: MITTELSTAEDT RAINER DIPL ING
IPC: H04M1/65
Filed: 1990-11-26
Abstract: Device combinations, consisting in most cases of telephone set, answering machine, telecopier, cordless telephone and so forth, are increasingly connected to the main station line in subscriber equipment. As has been shown by investigations, it should also be possible in future device combinations to transfer a message of the temporarily absent subscriber to a calling subscriber. The circuit complexity required for this and the costs are essentially determined by the signal processing of the voice signal and by the random-access memory used. To provide for signal matching, particularly for improved voice quality of stored announcements, a control device arranged in the subscriber terminal determines at the end of the announcement text the storage capacity of the digital memory still available for storing digital voice signals. If free storage capacity is still available, the frequency of the sampling clock for an A/D converter is changed when the announcement is copied from a magnetic tape memory into the digital memory, in such a manner that the digital memory is largely filled. <IMAGE>

Title: Sand spreading device for railways - using pressurised air jet to push sand around U-bend through exit pipe
Inventor: WUTZL HANS
IPC: B61C15/10
Filed: 1991-05-03
Abstract: Sand spreading device incorporating a pressurised air jet (15), with flexible nozzle (13) for directional blasting of sand. The sand is held in a funnel like box (1) beneath which an exit pipe (9) is situated. The exit pipe is housed by walls (4,5,8) with a small opening in the path of the air blast (15).

Title: Preliminary treatment of annealed steel billets - with billet core consolidated by shrinking cooled surface layer
Inventor: MEYER GERHARD DIPL ING
IPC: B21B45/02
Filed: 1991-10-18
Abstract: Annealed steel billets with a given exit temp. for subsequent rolling are cooled all over with a high heat transfer coefft. in such a way that a surface layer of certain thickness with a reduced temp. is obtd., while the core still remains approximately at the original exit temp. The shrinking cooler surface layer compresses the hot core and consolidates its structure. Further consolidation of the core by the rolling process is higher than that of the cooler surface layer of the billet. USE/ADVANTAGE - The method and installation can be used in metal rolling plants, especially in those following continuous casting plants. In contrast to the traditional practices, residual porosities of the billet core regions are totally eliminated. Cooling of the billet surface is achieved by means of pressurised water flow. The cooling installation is made up of individual cooling units arranged one after another. Water flow of each cooling unit is switched on when the head of the billet has traversed half the length of the unit. It is switched off when the tail of the billet leaves the entry opening of the unit. The individual cooling units can be displaced vertically relative to one another and horizontally relative to the direction of billet motion. They consist of top and bottom boxes, with the top box placed on and taken off the bottom box by hydraulic means.
