Patent DE-3146222-A1 (DE)
Title: Diaphragm pump with a diaphragm fracture display device
Inventor: ORLITA FRANZ
IPC: F04B43/00
Filed: 1981-11-21
Abstract: Two diaphragm layers (18a, 18b) which are individually fluid-tight are firmly clamped in their edge area. In the clamping area, two thin rings (25, 25') are located between the diaphragm layers (18a, 18b). The surfaces (25a, 25'a), of the rings, adjacent to one another are roughened, for example by sand-blasting. Due to the roughening a radial flow connection is created between the inner edges (30) of the rings and their outer circumference, through which connection, in the event of damage to the diaphragm, fluid penetrating between the diaphragm layers (18a, 18b) can pass to a sensor. The device is simple and inexpensive to manufacture compared to pumps in which the connection of the chamber between the membrane layers is created by shims with bored ducts. <IMAGE>

Title: Changeable score display for tennis
Inventor: AREND LEO
IPC: A63B71/06
Filed: 1982-02-26
Abstract: The invention relates to a score display for tennis which, by its construction, allows the result shown for the players to be changed as well when they change ends. The accompanying change of the results shown for the players on the display is made possible by the fact that the results are shown on the half of the display body which faces the player's side of the court and the display body is rotated through 180 DEG  about the vertical mid-axis by the umpire. As is visible in the attached drawing, despite rotating the display body through 180 DEG  when ends are changed, it is still possible to read the front and back. The result displayed for the player on half of the board is thus always the result for the player playing on the same half of the tennis court. The advantage of the changeable score display is seen in the fact that the spectators can read the respective results of the game at any time without causing a disturbance by the annoying questioning of an adjacent spectator.

Patent DE-3213333-A1 (DE)
Title: Use of general-purpose incandescent lamps and of methods to extend their life in lights of all types which are normally operated with long-life incandescent lamps
Inventor: BOGEN WOLFGANG
IPC: H05B39/09
Filed: 1982-04-07
Abstract: Since the average life of long-life incandescent lamps (Sig lamps) is approximately 6000 hours, the use of general-purpose incandescent lamps with more than double the rated power and the use of pulse operation to extend their life to more than 100,000 hours is more expedient. Pulse operation, which is barely detectable by eye, reduces the r.m.s. incandescent lamp current by means of phases between the pulse phases in which no current flows. In consequence, far better data are obtained when operating Sig lamps with respect to the light intensity, the colour temperature and, especially, the power saving. Such pulse operation is carried out, for example, using the 50 Hz half-cycles of the AC mains, whose phases in which no current flows can still be optimised by means of a phase gating angle of approximately 90 DEG . <IMAGE>

Title: Process and apparatus for drying moist bulk materials
Inventor: KORDA JEAN-PIERRE
IPC: F26B3/20
Filed: 1982-05-27
Abstract: For drying moist bulk materials, the bulk material is heated by means of heat radiation such as infrared radiation, which acts on the surface, smoothed as much as possible, of a stationary charge of bulk material, until the bulk material in the region of this surface has reached a predetermined degree of drying. The bulk material is then turned over and thoroughly mixed to a mass with uniform moisture content, then again allowed to stand, and its stationary smoothed surface is irradiated with heat from heat radiation sources. These two process steps are alternately repeated until the charge of bulk material has reached the desired degree of drying. The process is expediently carried out in a rapidly running mixer such as a ploughshare mixer, in the container wall of which, in the upper region, infrared radiators are incorporated.

Title: Method for detecting flat spots on rail wheels
Inventor: STOERMER OSWALD ING GRAD
IPC: G01M17/10
Filed: 1983-03-19
Abstract: The method serves to detect flat spots on rail wheels on travelling rail vehicles. For this purpose, the wheel contact force on the rail is continuously measured over at least one wheel circumference by means of a measurement section or in sections by means of a plurality of measurement points forming a measurement section. A mean value corresponding to the contact force of a wheel which is free of flat spots and at least one peak value is determined, by low-pass filtering, from the measurement values acquired in this way and the two values are compared with one another. The difference between these values or the quotient of these values is then a measure of existing flat spots. <IMAGE>
