Patent DE-3012526-A1 (DE)
Title: Continuous rolling mill loop control - by comparing scanning TV camera readings with desired settings
Inventor: BADAL JIRI DIPL ING
IPC: B21B37/50
Filed: 1980-03-31
Abstract: A loop control for a continuous process, esp. for continuous rolling mills, is based on scanning the position of the loop at >=2 points. The readings are averaged and compared with the desired value of the loop deflection. Any discrepancy produces a correcting signal for one of the stand motors. The prefd. scanner is a TV camera. Compared with a single-point scanning by revolving mirrors, this eliminates the fluctuations of the reading independent of the relative loop elongation.

Title: Short coupling for rail vehicles - has coupling head pivoted on fixing bracket, with tension and compression units on each side between head and bracket
Inventor: KLEIN WILLI
IPC: B61G7/12
Filed: 1980-10-03
Abstract: The short coupling for rail vehicles has a coupling head (11) with a mechanically or manually operated lock (12). The head is connected to the fixing bracket (19) by a universal joint held in slots in the bracket (19). On each side of the head between the head and the fixing bracket are tension and compression units (17). When in use the connecting joint is drawn to the front of the slot so that during braking the compression unit absorbs the shock. When the joint is turned the units tend to centralise the head by one unit being in compression and the other in tension, thus keeping a positive connection between vehicles at all times.

Title: Examining biological effects on foodstuffs of seeds - by measuring intensity of ultra-weak photon radiation in vitro
Inventor: MEHLHARDT WOLFGANG PROF
IPC: C12M1/34
Filed: 1980-10-10
Abstract: A measurement of the spontaneous or stimulated emission of ultra-weak photon radiation is used as an in vitro parameter of a cell lot. The parameter is used to detect possible cell-damaging or regenerating effects or to act as a quality control. The measured quantity is either the photon intensity or a photon statistic e.g. the distribution of numbers of photons emitted in a measuring interval. The ultra-weak radiation is typically in the infra red band and has an energy very much less than that of thermal radiation. Typically the radiation is 10 power (-10) less than thermal radiation. The radiation is detected by a photo multiplier with a gain of over 10 power 6. The method may be used to determine whether a cell lot is in a healthy state. Alternatively it can be used to determine the effect of an agent on the cells. The method is partic. suitable for quality control in foodstuffs.

Title: Door stop, especially for motor-vehicle doors
Inventor: KLINGENBURG SIEGFRIED
IPC: E05C17/28
Filed: 1981-06-05
Abstract: A door stop, especially for motor-vehicle doors, consists of a setting-out arm (1) to be articulated on one door-arrangement part, door or door spar and of a brake housing (14), through which the setting-out arm (1) passes and which is to be fastened to the other door-arrangement part and has two braking parts pressable elastically apart from one another by the setting-out arm according to camtracks. To improve the lifetime of such a door stop, the invention provides for the braking part to consist of two levers (20, 21) which are articulated on the brake housing (14) and are coupled at their free end by means of a tension spring (22, 23) and which can be spread apart from one another by two axle-mounted rollers (11, 12; 13) running on the cam tracks (24, 25). Since, in this design, essentially only rolling friction occurs instead of sliding friction and long tension springs can be used, a high wear resistance is achieved. <IMAGE>
