Title: Work roll of high chromium content and process for producing it
Inventor: NAKAMURA SHIRO
IPC: B22D19/16
Filed: 1981-04-23
Abstract: A work roll which, between an outer layer of cast iron containing 20 to 25% by weight of Cr and the core of a ductile cast iron containing less than 1.5% by weight of Cr, has an interlayer of cast iron which contains 5 to 10% by weight of Cr and is, in a metallurgical sense, integrally combined with the outer layer and the core, and a process for the production thereof are described. This work roll of high chromium content is produced according to the invention by forming the outer layer by casting the molten metal into the rotating mould of a spin-casting device, forming the interlayer by pouring the metal melt to give a cast iron having a chromium content of less than 1.0% by weight to the mould, before the inner surface of the outer layer has solidified, and finally forming the core by casting the metal melt to form a ductile cast iron core in the mould, the interlayer largely preventing diffusion of the chromium from the outer layer into the core.

Filed: 1981-06-12
Abstract: A variable-output hydraulic-fluid vane pump used in machine tools and industrial machinery has an auxiliary piston (5) with a spring (10) and a face (5') which is acted upon by the hydraulic delivery pressure of the pump in order to force a ring (7) into an eccentric position with respect to a rotor (8) with veins (9) which is situated in the ring. A main piston (4), which is arranged on the other side of the rotor and diametrically opposite the auxiliary piston, has a first end face which is kept in engagement with the ring (7). A pressure equalization device (3) which responds to an increase in the hydraulic delivery pressure, causes the hydraulic delivery pressure to act on the second end face of the main piston in order to control the amount of the eccentricity of the ring (7) with respect to the rotor (8). A fluid passage (24) contains a through-flow restrictor (12), and one end of the passage opens out on the second end face of the main piston, and its other end can be connected to a container (28). Such an arrangement for the variable-output vane pump according to the invention results in stability during operation, energy savings and a reduction in the noise and vibrations during operation.   <IMAGE>

IPC: G11B15/665
Filed: 1981-07-13
Abstract: In the case of a cassette apparatus for magnetic recording and/or playback, which is designed for the use of a small tape cassette, the magnetic tape contained in the cassette is drawn out with the aid of a pair of extracting devices in order to lay it from both sides around a guide drum until a certain angle is reached. The extracting device has a vertical pin and an oblique pin, which is able to swivel about the vertical pin in order that the device is able to move in a limited space of the apparatus. After drawing out the tape, the oblique pin is swivelled in such a direction that the end is laid further around the guide drum and consequently the tape is inserted. A pinch roller is fitted in such a way that it moves at least from a starting position to a predetermined position, likewise in the limited space on the same path as the extracting device. When the extracting device returns into its starting position, a drive mechanism for fast forward and reverse running is used to wind up the tape quickly in order to avoid slack tape.

Filed: 1981-11-26
Abstract: The invention provides for the heliostats (1) of a heliostat field of a solar power station to be used as antenna reflector surfaces for a radio antenna with a high directional characteristic and a high gain. To this end, an antenna horn (6) is arranged on a tower (5) of the solar power station in the immediate vicinity of an absorber (4) onto which the sunlight is concentrated during operation of the solar power station. The heliostats (1) focus electromagnetic radiation onto the antenna horn. In addition to the already existing capability of aligning the heliostats individually, the capability must also be provided for the incident electromagnetic waves on the heliostats to arrive at the antenna horn in the correct phase. For this purpose, for example, the mirror arrangements (3) of the heliostats can be displaced individually approximately at right angles to their surface. The maximum value of this displacement is in the region of the detected wavelengths. <IMAGE>

Title: Slideable character carriers for the hand printing of character combinations
Inventor: BERGK GEB EVERS
IPC: B41B1/02
Filed: 1982-01-21
Abstract: The subject matter of the invention are character carriers for the hand printing or writing of character combinations which can be coupled together by means of a dovetail fit on the side surfaces running perpendicular to the writing direction. The dovetail fit is constructed to be tapered in the direction of its guide so that no play remains between the character carriers which have been pushed together completely. In this manner, a stable linkage is formed from carriers of individual characters, with which linkage the entire word, the series of numbers or a different character combination can be printed or written at once in a straight line. Prior to that, the correct arrangement of the characters can be checked with aid of markers on the character carriers. The character carriers can have the most varied dimensions. In hand stamping, the dovetail fit is guided horizontally and in stencil plates perpendicular to the writing surface. The simple construction of the dovetail fit allows inexpensive and easy to handle learning aids to be produced which take up little space and can be used in a versatile manner. Using alphabet stencil plates, for example, school beginners can learn writing, reading and spelling at the same time.
