Patent DE-3315973-A1 (DE)
Title: Process and apparatus for the continuous casting of metals
Inventor: GETSELEV ZINOVIJ NAUMOVIC
IPC: B22D11/115
Filed: 1983-05-02
Abstract: The process consists in that liquid metal is uninterruptedly fed to a cooling mould. The liquid metal is acted on by the electromagnetic field of an inductor and a stabilising winding for the formation of a liquid metal column. The liquid metal column is then cooled to produce a strand. A current is supplied to the stabilising winding with a phase which lags that of the inductor current by an angle between 95 DEG and 165 DEG  and whose amplitude is 0.1-0.4 times that of the inductor current. The apparatus includes a cooling mould (1) which is formed by an electromagnetic inductor (2) and a stabilising winding (3) made of a nonmagnetic material and arranged coaxially with the inductor (2), with the vertex of the triangle turned towards the interior of the cooling mould (1). The relationship of the height of the triangle in the cross-section of the stabilising winding to the larger leg of the triangle is in a range from 0.7 to 0.96. <IMAGE>

Title: Filing appliance for receiving and holding computer sheets
Inventor: HERSE FRIEDRICH
IPC: B42F13/04
Filed: 1983-06-25
Abstract: The invention relates to a filing appliance for receiving and holding computer sheets. This is done by a cord or cords which passes or pass through the mutually aligned holes (7) in the two covers (1, 2) of the filing appliance and in the computer sheets (4) located between them. Said cord is at least sufficiently long for the opening out of the covers (1, 2) of the filing appliance with the sheets (4) not to be impeded. As a result, a relatively thick pile of computer sheets can also be held reliably by simple means and can thus be filed satisfactorily. On the other hand, however, the holding means do not impede working with the contents of such filing appliances. <IMAGE>

Patent DE-3408868-A1 (DE)
Title: Metallic information carriers, in particular focusing elements for the lens or the lens shutter of a photographic camera
Inventor: SPITZER MANFRED
IPC: B41M1/12
Filed: 1984-03-10
Abstract: The invention is based on the proposal no longer to proceed as before when dyeing the background of an information carrier by means of a contrast medium - an operation which always precedes the actual screen printing - and provide the surface to be printed with a primary colour entirely covering it, but as early as this operation to exclude the information to be printed in a manner congruent with the dyeing. The aim of this measure is to achieve that, for example, in the case of a focusing element, such as, for example, the focusing ring of a photographic lens or the lens shutter, which is to be operated by hand and is provided with a numbered scale, the readability of the information given by the numbered scale is maintained as a consequence of intensive use of such a component or careless handling and treatment of a camera, and is still available in a readable manner for the user even if the numbers, letters and the like should be affected by mechanical damage.
Patent DE-3410431-A1 (DE)
Title: Electromagnetically actuated fluid control valve
Inventor: HOMES GRAHAM DENNIS
IPC: F02M59/46
Filed: 1984-03-21
Abstract: A fluid control valve comprises an axially adjustable valve member 22 which is directly connected, via a valve-member rod 26, to the actuating member 29 of an electromagnetic actuating means. The valve member 22 has a head 23 which can be brought into contact with a seat 24 when the device is excited. In this operating condition, a step formed between the valve member and the valve-member rod lies outside the valve body 20 accommodating the valve member. Interacting with this step is a spring abutment 35 which is arranged in a sliding manner on the valve-member rod 26 and on which there act a return spring 36 which holds the valve open and a driving oscillation spring 39. The opposite end of the second spring 39 is connected to the valve-member rod and, during the movement of the valve member and of the actuating means into the open position, this spring 39 is compressed once the collar 35 has come into interaction with the body 20. The spring returns the valve member to its usual open position. <IMAGE>

Title: Luminaire housing in which a ballast is mounted
Inventor: REUSCH RUDOLF
IPC: F21V23/02
Filed: 1984-03-31
Abstract: In a luminaire housing made from plastic for tubular fluorescent lamps, use is made of two spring clips (6) instead of conventional fastening means, such as screws, serrated lock washers and nuts, in order to reduce the installation costs arising when mounting the ballast (3). For this purpose, lugs (5) of rectangular cross-section are provided on the device support (1) of the luminaire housing. The spring clip (6), which is produced as a stamped bent part, has a flat limb on one side of which a claw (9) is arranged. The limb contains a cutout which is matched to the contour of the lug (5) and extends as far as over the bent edge (13) forming the start of the claw (9). A pressing device is used to push the spring clips (6) with their cutouts over the lugs (5) until their claws (9) firmly press the retaining lugs (4) of the ballast (3) against bearing surfaces of the device support (1). The cutout edges situated in the regions of the claws are locked in this case against the lugs (5) and thus effect a permanent spring pressure. <IMAGE>

Title: Door leaf with aligning device
Inventor: SEIFFERTH HELMUT
IPC: E04F21/00
Filed: 1984-05-07
Abstract: A door leaf is described, which contains an aligning device for plane aligning, for example after warpage caused by weather, which device works reliably with the most simple construction, can be actuated conveniently and is constructed in such a compact manner that it can be sunk into the door leaf invisibly from outside. To this end, the aligning device, which consists of a tensioning rod and a threaded counterpiece which can be screwed to the tensioning rod, is inserted into a longitudinal slot incorporated into the frame stay of the door. The tensioning rod is secured against twisting by a projection projecting in a recess in the door. The threaded counterpiece is held rotatably, but secured against longitudinal movement, in an upper journal which likewise extends in a recess in the door. The upper side of the threaded counterpiece has screw driving surfaces which are accessible through the longitudinal slot from the upper side of the door. According to whether the spacing of the two fixed bearings formed by the projection on the one hand and the journal on the other hand is shortened by screwing the threads present on the tensioning rod and on the threaded counterpiece into one another or is lengthened by unscrewing, corresponding compressive or tensile forces are transmitted to the adjacent wood fibres ofthe door, as a result of which a compensation of the warpage is achieved.

Title: Slide closure for the blowing channel of metallurgical vessels, especially of steel ladles
Inventor: MAUS WALTER DR ING
IPC: B22D41/42
Filed: 1984-12-06
Abstract: The slide closure for the blowing channel of metallurgical vessels has, each with a bore, a stationary slide plate and a displaceable slide plate which is located in a slide portion. A conduit for blowing in gases, or solids suspended in gases, is attached to the slide closure. The slide portion has, on the side remote from the stationary slide plate, a hollow cylindrical flange through which the conduit is guided as far as the bore in the displaceable slide plate. The conduit has an annular disc and coaxial with this a hollow cylindrical section which projects into the hollow cylindrical flange and is connected to its end by an annular flange. These parts interengage in the fashion of a labyrinth seal. The interspaces bounded by them have a filling material of compressible, refractory material, e.g. refractory mortar. A body is formed, after the refractory mortar has set, which on the one hand is sufficiently compressible to compensate for the different thermal expansions of the individual parts and at the same time to ensure a gas-tight connection.
