Title: Method for the continuous casting of metals and an installation for carrying it out
Inventor: KORSUNOV EVGENIJ ALEKSEEVIC
IPC: B22D11/10
Filed: 1982-04-30
Abstract: The invention proposes a method for the continuous casting of metals, including the feeding of the molten metal (2) from a metal feed system via a metal feed pipe (8) to a continuous casting mould (14), the intermittent withdrawal of the strand (16) from the continuous casting mould (14) by a dimensionally accurate length while simultaneously feeding the molten metal, the production of a positive pressure from the side of the molten metal (2) on the strand crust to be formed, during the waiting times between the withdrawals of the strand (16) from the continuous casting mould (14), in which, after completion of the withdrawal of the strand (16) from the continuous casting mould (14), the molten metal (2) is fed from the metal feed system to an additional vessel (18) filled beforehand with an inert gas, a predetermined pressure being produced within the additional vessel (18) in the molten metal (2) and the strand (16) to be formed, after which a reciprocating motion of the molten metal (2) between the additional vessel (18) and the metal feed pipe (8) of the metal feed system is brought about and, during the subsequent withdrawal of the strand (16) from the continuous casting mould (14), the molten metal (2) of the continuous casting mould (14) is fed from the additional vessel (18) and the metal feed system. The invention also proposes an installation for carrying out the method according to the invention. The present invention can be used in the metallurgical industry in the casting of ferrous and non-ferrous metals, in particular in the production of strands from light metals and alloys based on aluminium and magnesium. <IMAGE>
Patent DE-3217085-A1 (DE)
Title: Fan blade on a fan
Inventor: BLOCK GUENTER
IPC: F04D29/38
Filed: 1982-05-07
Abstract: The invention relates to a fan blade on a fan, which is used especially for ventilation in tunnelling and underground. Instead of a narrow gap between the blades and the fan housing enclosing the fan blades, the blades are provided at their ends with end plates and a greater clearance is maintained between the end plates and the fan housing. In this way the risk of any contact between the fan blade and the fan housing and hence the danger of sparking is greatly reduced without losses in delivery capacity, owing to a pressure equalisation on each blade. The end plates in fact prevent this pressure equalisation to approximately the same extent as a narrow gap previously provided between each blade and the fan housing.

Title: Process and apparatus for the renewal of grassland and lawn areas
Inventor: ORTH GUENTER
IPC: A01C7/00
Filed: 1982-10-25
Abstract: The process according to the invention is carried out by cutting in the turf two parallel slits, the bottom of which has a changing height. The soil between the two slits is lifted out, and the groove thus formed between the slits is filled with seeds which are deposited at different heights. The slits are made by means of knives which are arranged on the circumference of a drum or of another machine allowing a periodic insertion of the knives. The tools each have a pair of knives which makes the parallel slits, and between the knives extends a cutting edge which permits a cross-cutting in the region of the groove, and this knife of blade-like form can serve at the same time for ejecting the soil. Instead, a clearing tine lifting out the soil can be arranged behind the knives in the running direction.

Patent DE-3309270-A1 (DE)
Inventor: GEGNER PETER ING GRAD
IPC: H04L7/00
Filed: 1983-03-15
Abstract: Transmission lines for digital signals may include a large number-for example, several hundred-of intermediate generators. In this case, telemetering units are provided at the end points and at intermediate points, by means of which the digital telemetry signals are generated and sent over the transmission lines together with the digital information signals. In the event of interference, a problem arises, due to the fact that the telemetry signal that is needed to identify the interference is only available after a comparatively long time. Therefore, according to the invention, a method is recommended for the initial synchronization, at bit rate, of the pulse generators which generate the bit pulse in the telemetering units. The pulse generation is accomplished with a phase-control loop which generates a signal pulse with a comparatively high frequency. This high frequency is broken down by a resettable frequency divider to the pulse frequency by setting the frequency divider with the first correct sync word recognition. This results in an intermediate synchronization.

Title: Device with an optical head arrangement
Inventor: KODAMA HIROSHI
IPC: G11B7/085
Filed: 1983-04-15
Abstract: A device with an optical head arrangement has a drive device (48) for an objective lens (82). An objective lens (82) for movement along a beam path is supported in the optics head (52) aligned with the vertical axis of the optics head (52). Furthermore, the objective lens (82) can be moved with respect to the optics head (52) along the optical axis by means of a coil (84) and a permanent magnet (80). A laser beam is guided via the optics head (52) onto a test surface (50) and reflected from there and detected by a detector (46). A difference amplifier (92) generates a signal with a level corresponding to the distance between the objective lens (82) and the test surface (50), and the optics head (52) is moved in the system (48) until this signal reaches a predetermined value. When the signal has reached a predetermined level, the drive device (48) is switched off, while the objective lens (82) is moved by the coil (84). In this way, the distance between the objective lens (82) and the test surface (50) is set so that it corresponds in focal length to the objective lens (82). <IMAGE>

Title: Smear-free transfer drum for sheet-fed rotary printing machines
Inventor: JAHN GEORG
IPC: B41F22/00
Filed: 1983-08-06
Abstract: In the drum shell of a smear-free transfer drum for sheet-fed rotary printing machines, blower holes (4) are distributed in a preferably even structure over the entire sheet-carrying drum circumference, air distributing elements (7) being arranged in said holes. The air-distributing elements (7) are made of air-permeable, elastic and easily compressible material with a low specific gravity and have hydrophilic properties. They are held in the blower holes (4) in a force-fitting manner by elasticity tension and/or in a positive-locking manner by construction with support collars (30). The air-distributing elements (7) preferably consist of a two-component composite plastic with a reversibly deformable, lower region of foamed material and an upper region of chemically reinforced nonwoven or crinkled chemical fibres. The fine structuring of the network of air-distributing elements (7) acts like a multiplicity of air ducts and causes a reduction in pressure and very effective extremely fine dispersion of the blower air flowing through, diffusing in all directions to form an even air cushion which supports the sheet. The possibility of using materials of differing air-permeability for the air-distributing elements (7) allows, by skilful selection of material, the air cushion to be adapted to the processing of sheets (27) of widely varied weights of paper (Figure 1). <IMAGE>
