Title: Telephone subscriber's appts. with opto-electronic reader for dialling - permits alphanumeric display of information being read and number being called
Inventor: PIRMAN KLAUS
IPC: H04M1/2755
Filed: 1979-09-27
Abstract: The modification is to a telephone set with pushbutton number selection and facilities for storing and recalling frequently used numbers and is intended to widen the range of automatic number selection. A hand operated optoelectronic reader (4) is attached to the telephone set. With it a name and number printed in a form suitable for automatic character recognition can be read and entered into the telephone memory. It can be used immediately to select the number read, or the number can first be set up an alpha-numeric display (5) for verification and then selected, for example by lifting the handset. Infrequently used numbers need not therefore be entered into the memory for automatic selection. The set also has a pushbutton panel (1), stored number selection panel (2) and a name selection panel (3). When using any one of these possibilities, the number or name selected can be displayed.

Title: Emergency cooling of gas cooled fast breeder reactor - by unborinated water sprinkled onto core and collected beneath
Inventor: KUMPF HERMANN DIPL ING
IPC: G21C15/18
Filed: 1980-09-25
Abstract: Emergency cooling method for gas-cooled, fast breeder reactors having a core with fission and breeder zones uses water sprayed onto the core from nozzles. Unborinated water is drawn from a tank to a max. quantity such that the water accumulating in the space beneath the core rises at most to the lower edge of the fission zone. Pref. in a reactor in which the core stands on a core support plate, the max. quantity of water in the reservoir is such-that the highest level to which it can rise beneath the core still leaves sufficient space for circulating gas. Used for gas-cooled, esp. helium-cooled fast breeder reactors, in which the core components including the fuel are compatible with water. Fine sprinkling of the water also virtually avoids thermal shocks. The water which does accumulate in the bottom zone below the core can be recycled and sprayed in again at the top.
Patent DE-3036341-A1 (DE)
Title: Model representation of seasonal and geographical day lengths - uses globe with surface mounted sensors to reproduce light intensities via LED(s)
Inventor: SZOSTAK ROLAND PROF DR
IPC: G09B27/08
Filed: 1980-09-26
Abstract: To represent the conditions of daylight and length of days over the earth's surface, a normal geographic globe is used, illuminated by an external light source. Photo-electric sensors mounted at different points on the globe's surface, pick up the light at different intensities, depending on their position relative to the incident light, when the globe (2) rotates. Thus for instance, if one sensor is mounted in Central Europe, the associated external lamp i.e. L.E. connected to it, will light up periodically to represent the brightness of day in that locality. Depending also on the orientation of the globes axis, to the light source, a visual demonstration can be given of the connection between winters and summers in northern and southern hemispheres.

Title: Repeated electroplating of roller used for rotogravure - where permanent underlayer permits thin electroplated metal top layer to be used so substantial savings in cost are obtd.
Inventor: HEIN BERTOLD DIPL ING
IPC: C25D7/00
Filed: 1980-11-11
Abstract: A roller is provided with a permanent, impermeable underlayer (I), which is not attacked chemically or anodically, but provides good adhesion for an electroplated metal coating (II) which is repeatedly deposited and removed. The underlayer pref. consists of two coatings, e.g. a layer (Ia) of Ti or Ta which forms a barrier layer on the roller, and then a layer (Ib) of Au, Pt, Pd or other noble metal providing adhesion for a top coating (II) which is Cu or Ni repeatedly and removed. Alternatively, the underlayer (I) is pref. a ceramic contg. a dopant so it conducts electricity; or a layer (I) of carbon or graphite. Instead of using a layer (II) 0.12 mm. thick, which is required in conventional printing operations, the invention requires a layer (II) only 0.03 mm. thick, so the saving in metal and time is 75%.
