Title: Sun-ray protection for seated people - comprises insulated blanket placed over exposed parts, esp. useful in cars
Inventor: PREISS ALFONS
IPC: A47G9/02
Filed: 1979-05-09
Abstract: An insulated cover is used to effectively protect the parts of the body exposed to the suns rays. Although normally used to keep a person warm these insulated covers or blankets are also effective in keeping a person cool. Although usually provided with heat-reflecting layers they can also have layers of a material which is a poor heat-conductor. These covers are of particular use when driving since the normal sun-screening measures would obscure vision.
Patent DE-2922239-A1 (DE)
Title: Vaccination needle penetration sensor - uses reflected light passing through optical fibres to phototransistor to produce visual or audible indication w.r.t. penetration depth
Inventor: MATSUO KAZUMASA
IPC: A61B90/30
Filed: 1979-05-31
Abstract: With present methods, it is difficult to determine whether an e.g. pneumo-peritoneum needle has penetrated too far, thereby injuring an internal organ, or not far enough. This invention uses reflected light to trigger a visual or audible signal. A light source (8) faces one end of an optical fibre (5) inside the needle the far end of which coincides with the tip (X) of the needle. Another optical fibre (6), lying alongside the first, returns reflected light to a phototransistor (10) which faces its near end and which is screened (9) from the light source. The output of this phototransistor drives a l.e.d. which serves as a visual indicator. Alternatively, this output is further processed in an electronic circuit including a comparator to drive, in addition to the l.e.d., a loudspeaker producing an audible alarm signal, depending on the intensity of the reflected light.

Title: Coating apparatus for pharmaceuticals or foodstuffs - has solvent evaporated from coating under vacuum while inside coating chamber
IPC: B05D3/02
Filed: 1979-06-05
Abstract: A method of coating small objects with solvent-contg. substances consists of drying the objects in a vacuum stage inside the coating plant. More specifically, air, protective gas or other other medium can be supplied to and removed from the coating chamber. The solvent may be recovered and reused, solids being removed by filtration. Used for the production of sweets, chocolates, medicaments and the like. By carrying out the drying process in a vacuum region which forms part of the coating plant itself, the drying process is greatly speeded up and the solvent is removed without being wasted. For heat-sensitive particles such as medicaments, a lower drying temperature can be used.

Patent DE-3001440-A1 (DE)
Inventor: GRANZOW WOLFGANG-DIETER DIPL I
IPC: B61L21/00
Filed: 1980-01-16
Abstract: The signal term to be transmitted to a railroad traction vehicle is formed in a signaling system in that each element, from a destination element back to a start element has a respective top speed assigned thereto as an identification. The identification is transmitted element-by-element back to the start element and is devalued during relaying thereof when the identification is greater than that prescribed for a travel path element having a lower assigned top speed so that the identification received at the start element indicates the top speed admissible for the route. The admissible top speed is then converted into a corresponding signal term.

Inventor: HELD FRITZ PROF DR
IPC: B62D55/205
Filed: 1980-02-11
Abstract: The crawler chain for a track-laying vehicle, in particular for armoured vehicles, has connecting pins (16). Each pin (16) consists of a metal bolt (8) with vulcanised-on rubber sleeve (13). When the pin (16) is inserted into the bores (5) of the chain elements (1, 2), the said pin is elastically deformed. The sleeve (13) is of single-component construction and has thicker and thinner points (14 and 15) whose material thicknesses are greater (S0) or smaller (S2) than the difference between the radius of the bolt (8) and that of the bores (5). By virtue of this design, a longer service life and a smaller chain extension are obtained since the connecting pin (16) completely fills the bores (5). <IMAGE>
