Title: Constant-rate carbon dioxide generator for aquarium - having system in which overpressure in diffuser automatically reduces gas generation
Inventor: REISS MANFRED
IPC: A01K63/04
Filed: 1975-12-06
Abstract: Appts. for the controlled rate of prodn. of carbon dioxide for feeding plants in an aquarium has a container partly filled with limestone, this container is placed inside a second vessel contng. acid which passes through a tube in the first container to the limestone, and the carbon dioxide produced passes through a hole at the top of this first container to a diffusion chamber immersed in the aquarium. The chamber has e.g. PTFE or silicone walls permeable to gas. The carbon dioxide diffuses out into the aquarium more slowly than it is generated, the resultant pressure rise forces the acid downwards in the tube away from the limestone. Acid only thus reaches the limestone as is required to maintain working pressure.

Title: Sewage sand trap - producing air bubble streams across annulus and upwards in double cylinder tank
Inventor: STRATE WILHELM
IPC: B01D21/00
Filed: 1976-01-30
Abstract: A sand trap receives the sewage through a tangential inlet to an inner cylinder, open at both ends, and discharges the sand free liq. tangentially through an outer cylinder. A collector at the conical bottom of the outer cylinder retains the sand and other heavy particles. An air bubble stream is produced in the bottom neck of the annulus between the cylinders, and another air bubble stream is directed upwards away from the intake of the air pump for the sand. This ensures a uniform and trouble free sepn. of sand and other heavy particles. Floating and suspended particles are not deposited together with the sand. The floats need not be treated separately.

Title: Overhead mine conveyor car tilting mechanism - has vertical suspension arm housing piston operating worm gear to tilt container
Inventor: PIRAGES SIEGFRIED
IPC: E21F13/00
Filed: 1976-08-05
Abstract: The overhead conveyor in a mine has cars travelling along tracks suspended from beams (9) each in turn supported by trolleys which run along the tracks.

Title: Table leaf used for camping and in garden - has moisture-proof edge reinforcement injection moulded on at high temp.
Inventor: MEIER MAX
IPC: A47B13/08
Filed: 1977-04-29
Abstract: A leaf for a table or similar, esp. one for use in damp conditions, such as a camping or a garden table, consists of a panel of wood or woody material. It is coated above and below with a film of synthetic material, and all round the edge there is a protective strip of thermoplastic resin. The protective or reinforcing strip is suitable thermoplastic material which is injected under high pressure and at approx. 250 degrees C directly on to the outer edge of the board. The reinforcing strip has the form of a normally glued-on strip, which extends over the top and bottom edges to grip the board. It may have a projecting flange round its bottom edge which facilitates handling. The synthetic material is cast on to the edge of the board in an injection mould, the sections of which form the cavity which is filled to mould on the protective strip. In the zone of the reinforcing strip, additional sealing strips of PTFE may be fitted along the edges of the leaf. The difficulty that with all glued-on protective strips, the damp penetrates between the contact surfaces is overcome. This allows table to keep its appearance for longer.
