Title: Antitheft device for public servants exposed to risk - comprises worn alarm transmitter and receiver at central station to monitor changes in breathing rate
IPC: G08B21/02
Filed: 1986-01-21
Abstract: The transmitter is carried by a person in danger of attack or robbery.

Title: Aerodynamic profile, as well as an aerodynamic object provided with such a profile
IPC: B63H9/06
Filed: 1991-05-03
Abstract: An aerodynamic profile has a profile nose, a profile tail, as well as top and bottom profile sides which extend between the nose and the tail, the profile nose and profile tail being in the form of an arc of a circle in cross section. The distance between the centre points of the circles which circumscribe the profile nose and the profile tail is at most equal to the chord of the profile when the circles are in contact with one another and is at least equal to the radius of the largest circle, while the radius of the profile nose is smaller than the radius of the profile tail. A profile of this nature can be obtained in an aerodynamic object, such as a sail or a wing, if the nose and tail of the object are each defined by two rotationally symmetrical, for example cylindrical, bodies which touch one another.

Title: Device for rapidly establishing whether a diamond is genuine
Inventor: VISSER ROBERTUS GERARDUS
IPC: G01N33/38
Filed: 1994-06-15
Abstract: The invention relates to a "Yes/No" diamond tester for rapidly checking whether a diamond is genuine, irrespective of whether this is set in a setting. The invention is eminently suitable to be embodied as a portable instrument, since energy is drawn from the supply source during a test only. The test method makes use of a transistor as a sensor which must attain a preset junction temperature within a specific time, as soon as the device has been switched on by means of the measuring pin being depressed inwards. If the precious stone to be examined proves to be a genuine diamond, this will counteract, via a thermal-conductivity "measuring pin", the rising-temperature profile in the transistor, said phenomenon being detected and being suitable as a yardstick, since a diamond has a highly unique thermal conductivity. This test method renders a stabilized supply source unnecessary, nor is a so-called warming-up time required. All this results in very advantageous energy consumption!
