Title: Developer system for heat sensitive image formers - has twin heat input process with organic silver salts and reducing material obviating liq. developing and fixing
Inventor: FUJII MOTOHARU
IPC: G03C5/58
Filed: 1977-01-26
Abstract: The developing system is constructed to operate with material treated with organic silver salts as opposed to normal inorganic silver salts requiring subsequent web processing. The latent image is formed by the controlled application of heat. A second specific level of heat is applied in order to complete the development process. The material is first exposed (a) and then conveyed to the first developing stage (b). A density measuring stage (c) follows. Depending upon the values ascertained, the second developing stage (d) produces a fully developed, full-range end result. The degree of development can be controlled by temp., time or pressure exercised by the heat-applying rollers (21) surfaces (20).

Title: Silicon nitride honeycomb structure - mfd. by thermally spraying silicon powder on graphite substrate and parallel strips
Inventor: TANK EGGERT DIPL ING
IPC: F28F7/02
Filed: 1977-10-03
Abstract: A honeycomb structure of silicon nitride as used for recuperative heat exchangers of gas turbines, is produced by thermal spraying of silicon powder with a particle size of 10-60 mu on a graphite substrate. Parallel graphite strips of trapezoidal cross-section are laid on the film and the whole is covered by another thermally sprayed silicon layer. Graphite strips of the same shape are laid inverted into the grooves and the whole is covered by a thermally sprayed plane silicon layer. This is continued between retaining side strips until the desired height is reached. The graphite is finally removed by annealing in air, and the honeycomb structure is annealed in nitrogen to convert Si into Si3N4. This eliminates thermal stresses and distortions caused by the vapours and softening of the conventional organic bonding medium and poor adhesion between the silicon foils. The resulting structure is dimensionally accurate and uniformly strong.

Title: Shock absorbing grip for tennis racket handle - has outer layer of textile to absorb perspiration
Inventor: KRIEG BENNO PROF DR
IPC: A63B49/08
Filed: 1978-02-06
Abstract: The handle of a tennis racket has a shock absorbing grip (2.1) of rubber or other elastomer. The handle (2.3) is covered with a layer of adhesive (2.2) in order to retain the grip (2.1). A second layer of adhesive (2.5) is applied to the grip (2.1) which is then covered with an absorbent fabric (2.4). This use of two materials ensures that the shock when the ball strikes the racket is absorbed by the elastomeric grip (2.1). At the same time the absorbent textile (2.4) absorbs any perspiration from the user's hand and so reduces the risk of the racket slipping out of the hand.

The elements vary only in whole multiples of the element of a minimum height and the construction kit elements fit above each other and/or next to each other so that a combination item of furniture is produced which is both serviceable from a functional angle as well as visually attractive.
Patent DE-2808621-A1 (DE)
Title: Solid electrolyte oxygen sensor - having metal oxide mix in electrolyte cup with heat resistant stopper and seal
Inventor: HORI RYUZO
IPC: G01N27/407
Filed: 1978-02-28
Abstract: Oxygen sensor element consists of a solid electrolyte vessel with a metallic pole on its inner reference surface. It has a second metallic pole on its outer test surface. The vessel or cup is filled to a specified level with a metal/metal oxide mixture which serves as a reference source of O2. The cup is sealed by a stopper which contacts the mixture. A heat resistant sealing medium is used to seal the stopper in. The vessel is cup shaped with a closed end. The stopper can be threaded or smooth and should be made of the same material as the solid electrolyte. If not, it should have the same coefficient of expansion as the solid electrolyte. The seal can be a glassy material. This can be applied as a soln. to the stopper. Used esp. for monitoring exhaust gas streams from i.e. engines before passing them to catalyst beds for cleaning up. It is necessary to seal such a cell because if exhaust gas gets inside, it affects the O2 potential of the reference mixture and upsets the calibration. The use of all glass seals is known but these give poor thermal shock resistance. The seal with the stopper is operationally safer and more reliable.

Title: Solar energy recovery system - using mixt. of capillaries with heat transfer fluid running through to give high temp.
Inventor: DIETZSCH HANS-JOACHIM
IPC: F24S10/70
Filed: 1978-06-28
Abstract: The capture, conversion and use of solar energy involves exposing fibre like capillary tubes to the radiation. These are formed into layers and fluids (liquids or gases) pumped through them. The fluids then absorb the heat from the surface of the capillary and allow it to be carried away for use. The capillaries absorb the long wave or IR components of the radiation into the fluid which then carries it along the surface actually exposed to the radiation. A convective current is established within the layer with liquid progressively moving towards the exposed surface which is the hottest. The capillaries can have a uniform absorptivity to wavelength or localised variations can be built in. Used to recover solar energy, of particular interest in horticulture where they can be used to provide partial shade with the heat so absorbed being put to good use. It can provide temps. >100 degrees C and therefore can be used for electrical power generation.
