Patent DE-2504119-A1 (DE)
Title: Two cylinder IC engine - pistons are rigidly connected and joined in pairs to a common gudgeon pin
Inventor: HABEREDER ALBERT
IPC: F02B75/28
Filed: 1975-01-31
Abstract: The engine consists of at least two parallel cylinders (4) closed by upper and lower cylinder heads (5) to form four combustion chambers each with a sparking plug bore and inlet and exhaust valve seats. Each cylinder contains two pistons (1) rigidly connected to each other at their base with a single gudgeon pin passing through the two cylinders via an elongated slot and sealing plates to transfer their reciprocating motion to a single connecting rod (12) between the two cylinders. The inlet and exhaust valves are actuated by cams in the conventional manner and timed so that each piston performs one stroke of the otto cycle in succession per half crank shaft revolution. The cylinders could be arranged in 'V', star, or horizontally opposed order to turn a common crankshaft.

Title: Combatting injurious organisms by plasmolysis - with non-toxic agents, eg sodium chloride
Inventor: LINDNER ARNO
IPC: A01N61/00
Filed: 1975-02-20
Abstract: Injurious organisms (e.g. weeds, insects or algae) are combatted using non-toxic agents (esp. NaCl) which act osmotically on the living cells of the injurious organisms (plasmolysis) and kill them by removing the cell fluid. The agents used are non-toxic and therefore do not give rise to pollution problems. The agents are inexpensive and readily available, and they can applied with existing equipment. The injurious organisms are killed by applying hypertonic solutions of the agents. Since the osmotic pressure of the injurious organisms is known or can be measured, the amount of agent required can be calculated and in this way the agents can be employed to give selective destruction of certain pest organisms.

Title: Crucible for oxidising smelts, esp. in monocrystal prodn. - is internally coated with non-alloying metal esp. gold
Inventor: SCHMIDT WALTER DR
IPC: F27B14/10
Filed: 1975-03-06
Abstract: A crucible for oxidising smelts is made from a high m. pt. metal, esp. W or a Pt metal, such as Ir. The inner face of the crucible is covered with closed skin of a metal which does not alloy, or alloys only sparingly, with the crucible material and which has a low affinity for oxygen. Pref. a metal having a large surface diffusion is used, specif. a liq. coating of Au (alloy). The process is used typically for monocrystal growth by the Czochralski method. The Au has almost no affinity for oxygen, does not alloy with W and does so only slightly with Ir. The crucible life is increased and the purity of the smelt is improved.

Title: Tasty cereal flake prodn. - by coating flakes with aroma materials opt. contg. chopped oil fruit or nuts
Inventor: LAMMERS ALBERT
IPC: A23L7/148
Filed: 1975-06-23
Abstract: The flakes, forming a ready-to-eat meal, are prepd. by coating the flakes with a layer of natural aroma materials, i.e. aromas of fruit, vegetables or spices. The aroma can be applied by steeping the flakes in aroma-contg. liqs., e.g. fresh or conc. fruit- or vegetable juices. The flakes are dried, esp. at 20 degrees C. Viscous and pasty materials, e.g. honey, are applied by first coating these materials, as a thin film, on rollers. The thin film is then transferred to the flakes by contacting the flakes with the rollers. Pref. flakes are pressed at room temp. and dried at 45 (25) degrees C. Oil fruits or nuts are de-oiled before incorporating to juices or pastes to be applied. A ready meal is prepd. cheaply, the flakes being consumed straight from the packet. They have a high nutritional value.

Title: Height adjustable manhole supporting cylinder - has plastics covered connecting and adjusting screw thread between concentric portions
Inventor: SCHMID JUN KARL
IPC: E02D29/14
Filed: 1975-06-24
Abstract: An adjustable level manhole cover can be readily and accurately adjusted to the level of the road surface without excavation. It can be adjusted for example after applying a new layer of surfacing material to the roadway.

Title: Rig for producing cylindrical vessel - uses sheet bent into roll and held for welding by expanding scissor-linked struts
Inventor: POTOCNJAK TOMISLAV
IPC: B21D51/18
Filed: 1976-01-08
Abstract: The method of fabricating cylindrical vessels on site makes it possible to reduce setting and welding operations considerably. It uses a sheet of length equivalent to the circumference of the finished vessel. The sheet is welded together in the works from several strips which are slightly inclined to achieve a vertical connecting weld at which the ends of the longitudinal welds do not meet. The sheet is then rolled into a coil by a wheel (10) and transported to site. The wheel consists of a number of vertical struts (20) along a circular path. The struts are connected to a central column (11) by scissor linkages (23,24) with linkage arms hinged at one end to the struts (20) and at the other ends to rings (25,26) sliding on the column (11). By moving the two rings towards the exact diameter of the vessel. The two vertical edges of the sheet are set together, and a single vertical weld produces the complete shell of the vessel.

Title: Printed instruction for dancing step sequence - uses basic foot-shaped symbol with additional enclosed line figure illustrating step
Inventor: HARTMANN GEB NIST GERTI
IPC: G09B19/00
Filed: 1976-05-10
Abstract: The representation of dance steps on printed instruction sheets uses a basic hexagon approximately foot-shaped symbol. The position and orientation of these symbols, relative to each other, indicates the foot movement during a sequence of dance steps. In order to convey additional information without using text, each symbol is also provided with a line or figure marking. In this way, each type of dance step can be represented by an individual marking. This method is easier to follow than a description of steps in text form.
