Title: Diaphragm-type distribution pump - has lever moving diaphragm clamped by flange between upper and lower body sections
IPC: F04B53/10
Filed: 1976-06-23
Abstract: The diaphragm-type distribution pump has top and bottom sections sealed to each other to form the body, the diaphragm (20) being clamped between them by means of its non-perforated flange, so as to form a closed chamber (22) between it and the top section. The volume of this chamber is varied by means of an actuating lever (26) bearing against the underside of the diaphragm and pivoting in the body. The lower part of the latter has an inlet port (36) leading from the fluid reservoir (34) to the joint face with the toip section, which has a hollowed-out-portion opposite it extending from the flange edge to the pump chamber. Thus the flange acts at this point as a flap valve opening upwards. There is also a delivery port in the upper section from the pump chamber to the upper side of the flange at another point, above a hollowed-out portion in the lower section allowing the flange to open downwards and the fluid to be discharged to atmosphere.

Title: Self:supporting sandwich panel for roofs and walls - has expanded polystyrene layer between two chipboards and laths
IPC: B32B21/08
Filed: 1977-11-14
Abstract: A self-supporting sandwich panel is formed of a layer of insulating material which is bonded by adhesive or similar between two chipboards. On one side of the panel wooden laths are provided, and these for pref. are also fixed on with adhesive. These wooden laths are fitted in the direction of the inclination of the roof. The side edges of the panels aligned to the slope of the roof are provided with ribs and/or grooves. The ribs and/or grooves are formed directly into the insulating material and the two chipboards. At least two opposing side edges of the panel are formed by wooden laths positioned so that the layer or insulating material is enclosed by them and the chipboards. The ribs and/or grooves are formed in the laths positioned in this way. The insulation material is an expanded resin such as polystyrene, polyurethane, etc. The chip boards are proof to boiling, are water tight and proof against mildew. Panel is used for the cladding of walls and partic. of roofs to be titlted or slated. The panel allows the use of lightweight rafters and supports generally. The panels can be made in sizes to support particular application as regards the degree of insulation and their unsupported span. The laths are laid on to suit the inclination of the roof with the tile or slate timbers resting on them so that air can circulate continuously in the space between.

Title: Compact tape cassette with inbuilt head cleaning facility - uses short lengths of cleaning tape between magnetic tape and lead tapes
IPC: G11B23/087
Filed: 1989-09-25
Abstract: With the exception of the novel cleaning facility, the cassette is a conventional compact cassette, commonly used for recording music, speech, etc. The repeated use of cassettes builds up deposits on the record or play heads, leading to a reduction in the amplitude and quality of the recorded or played back signal. The present cassette incorporates lengths of conventional cleaning tape (3, 5) between the magnetic tape (4) and the non-magnetic lead-in tapes which normally attach the magnetic tape to the supply and take-up spools (1, 7) of the cassette.

Title: Shearing device
IPC: B26D1/09
Filed: 1993-02-05
Abstract: The invention relates to a shearing device for shearing blocks of material, which is provided with a first blade, which is arranged directly opposite a second blade, and with a positioning member for positioning a block of material which is to be sheared. In the at-rest position, the first blade is located below the level of the positioning member. At the ends, the two blades are placed in slide guides, along which the blades can be moved towards one another. In the area of at least one of the slide guides, the device is provided with a pulling member which, with the aid of drive means, is able to apply a tensile force, by means of which the second blade can be pulled towards the first blade until the second blade comes into contact with the block of material which is to be sheared and has been placed on the positioning member. Then, the same tensile force moves the first blade towards the second until the first blade also comes into contact with the block of material which is to be sheared, after which the two blades are pulled towards one another through the material which is to be sheared. The pulling member comprises a pulling rod which on one side is pivotably attached to the end of the second blade and which at the other end is pivotably attached to an eccentric extension of a rotational shaft.

Patent PT-87600-A (PT)
Inventor: PIEPER HELMUT
IPC: C03B5/235
Filed: 1988-05-27
Abstract: Raw materials are fed into the charging end of a melting section which is heated by electrodes in the glass bath. The melted charge is then clarified under fossil fuel burners in a clarifying section, where the highest temperature of the furnace is maintained, and homogenized in a homogenizing section from which the clarified melt is drawn. Flue gas from the clarifying section sweeps the surface of the melting section countercurrently to the charge and is then used to heat combustion air. Burners in the clarifying section are operated under air starved conditions to reduce nitrogen oxides, while burners in the melting section are operated with excess air to achieve complete combustion.

Inventor: ARENZ HELMUT
IPC: B29C61/08
Filed: 1989-02-03
Abstract: The invention relates to a method for sectionally sheathing objects with plastic, which is distinguished by the fact that a crosslinked tube produced from a shrinkable plastics material is stretched axially or radially under the effect of heat. Subsequently, this tube is cut axially for the formation of a shrinkable band. A predetermined length of this shrinkable plastics band (6) is laid around an object (18) over a predetermined section and held in a position sheathing the object. By supplying heat, the shrinkable band laid around the object is shrunk closely around the object to be sheathed, and the end sections of the shrunk band which are brought into contact against each other are bonded to each other under the effect of pressure and heat. Furthermore, the invention comprises a device for sectionally sheathing objects with plastic, which comprises: a means for wrapping around a shrinkable band (6), around a section of the object (18) to be sheathed, a means (11, 12) for holding the end sections of the band laid around the object, a means for pressing together the end sections of the band, a means for severing the ends of the band section as well as a means (19) for heating the shrinkable band to the shrinking temperature. <IMAGE>
