Title: Low oil pressure indicator for i.c. engine - if pressure fails after period of normality having provides audible warning
Inventor: MEINERS HANS JOACHIM
IPC: F02B3/06
Filed: 1979-10-09
Abstract: The low oil-pressure switch (4) and warning light (5) for a car engine is supplemented by an audible alarm (7). To prevent the alarm from sounding before the engine is running, it is connected to the switch via an AND circuit (6). The AND circuit is controlled by a 1-bit store (1) which is reset (R) via a capacitor (3) when ignition is first switched on (2). When the oil-pressure switch opens, the store is set (S) and this enables (Q,A) and AND circuits. If the oil-pressure switch should now close, the alarm (7) will sound. The alarm can be fitted retrospectively without modifying existing circuits.

Title: Radiation coagulator
Inventor: NATH GUENTHER DIPL PHYS DR
IPC: A61B18/28
Filed: 1981-02-27
Abstract: In a radiation coagulator having an electrical incandescent lamp (14), especially a low-voltage tungsten-halogen lamp, as the radiation source and a tissue contact body (22) made of a crystalline, dielectric material transparent to the radiation and forming a contact surface (22c) for contact with a live body tissue, the temperature coefficient (reciprocal of the temperature resistance) and the heat absorption capacity of the contact body, where appropriate, in connection with a heat sink provided thereon, are so high that the heat arising in the tissue bearing against the contact surface is guided away from the tissue contact body to a considerable extent. The maximum radiated power density at the tissue contact surface is 150 W/cm<2>. These measures prevent an excessively fast or great temperature rise at the tissue surface, and this leads to a considerable improvement in the coagulability, especially for severe parenchymal haemorrhages, and to reduced adhesion to the tissue contact surface, and permits gentle and, if desired, deep coagulation. The tissue contact body (22) furthermore has no exposed sharp edges which may cut into the tissue and injure it or cause an excessive radiation concentration. A preferred material for the tissue contact body is monocrystalline sapphire, while other suitable materials are beryllium or magnesium oxide or monocrystalline quartz.   <IMAGE>

Inventor: RATH EWALD
IPC: A61F13/20
Filed: 1981-03-09
Abstract: A tampon (1) with catching thread (22) for medical or hygienic purposes comprises a bag which is made by wrapping a fabric piece which is folded so as to have two or more layers, or two or more fabric pieces (3, 4) which lie on top of one another and which are passed through a rubber ring (8) together with the catching thread (22) lying in between. In order to increase the tying-on strength of the catching thread (22) it is provided, according to the invention, that the catching thread is wound around two edge regions (7, 7), which are passed through the rubber ring (8), of the outer piece layer (4) of the piece and projects by its two end sections (23, 24) out of the tampon, the end sections being brought together, for example, by a knot (25). By this design the catching thread is a closed loop, so that it cannot slip out of the tampon even if a smooth thread material is used. <IMAGE>

Title: Device for sorting boards
Inventor: KLIE HARALD DIPL ING
IPC: B07C5/14
Filed: 1981-07-30
Abstract: The manufacture of boards generally results in boards of different qualities. It is therefore necessary to carry out quality control in such a way that the boards emerging from a planing machine, especially profiled boards made of wood, are visually checked and, after allocation to an A-quality or a B-quality, are fully planed and delivered to a collection point which corresponds to the quality in question. In order to permit a single operator to carry out this quality control simply and without undue effort, even in the case of long profiled boards, a device is proposed, which is provided with a first transverse conveying path, below the discharging end of which there is arranged a cartridge for receiving A-quality boards in a stackable manner, and to which device there is connected a second transverse conveying path above the discharging end of the first transverse conveying path at a distance which is greater than the board thickness, a further cartridge for receiving the B-quality boards in a stackable manner being arranged below the discharging end of the said second transverse conveying path.
