Title: Drying cylinder which can be heated with steam
Inventor: SCHIEL CHRISTIAN
IPC: D21F5/10
Filed: 1984-03-31
Abstract: The cylinder casing of a drying cylinder has on its inner surface circumferential grooves, in which the condensate arising from the steam collects. To remove the condensate, small suction tubes penetrate into the circumferential grooves. For the purpose of increasing the heat transmission through the condensate situated in the circumferential grooves, there is arranged in each circumferential groove a turbulence coil, i.e. a helically shaped bent wire. The pitch of the helix of the turbulence coil can be different over the circumference of the cylinder casing.

Patent DE-3445273-A1 (DE)
Title: Heat exchanger
Inventor: MUELLER WILFRIED
IPC: F28D21/00
Filed: 1984-12-12
Abstract: The air/water heat exchanger at the air side is connected to the flue-gas part of a tiled stove or fireplace. It cools the hot flue gases, which after all would otherwise escape through the chimney, and converts the energy extracted into hot water, which can be fed to a storage tank or heating system present. This conversion of the form of energy takes place in a so-called booster heater on which the whole heat exchanger is based. In order to avoid thermal problems, this booster heater is surrounded by three separate copper tubing spirals which in turn are protected by an outer shell against convective heat loss. A circulation pump removes the water heated in the copper tubing spirals and supplies cold water, etc.

Inventor: DYMA HORST
IPC: B41J1/30
Filed: 1984-12-24
Abstract: In printing devices which are to print automatically readable script in particular great value is placed on an entirely accurate and clearly readable printing script because otherwise the reading devices recognize erroneous characters or the documents are rejected. In order to produce easily readable characters and in order to increase the life of the corresponding type wheels it is proposed either to move the document (8) by means of a step motor (SM) with micro-step control (MP, D/A1, D/A2, V1, V2) and to arrange the characters, which are to be arranged flush right or flush left, according to convention, in the center (FIG. 2A) and to bring about the flush right or flush left printing by means of the micro-step control. In addition, it is suggested, according to the invention, to also control spoke type wheels (1) with different pitches by means of a type wheel drive motor (M) provided with a micro-step control (MP, D/A1, D/A2, V1, V2).

Title: Method and device for two-coordinate measurement using an interference technique
Inventor: PRIPLATA HEINZ DIPL ING
IPC: G01B11/00
Filed: 1985-06-10
Abstract: The invention relates to a method and a device for two-coordinate measurement using an interference technique, in particular in the case of length measuring machines. When measuring the displacement of a first carriage along an X-coordinate, the first step is to lock a second carriage, supporting a measuring reflector, which is mounted orthogonal to the first carriage. The signals generated by the photoreceivers assigned to the two measuring beam paths that are present are fed to an evaluation device. When measuring the displacement of the second carriage along a Y-coordinate, the first carriage is locked. The signals generated by the photoreceiver assigned to the measuring beam path assigned to the second carriage are fed to the evaluation device. Measured values proportional to the displacements of the carriages are determined in the evaluation device from the signals. <IMAGE>

Title: Profiled sail
Inventor: LEFEBVRE ANDRE
IPC: B63H9/06
Filed: 1985-06-20
Abstract: A profiled sail for a surfboard has a mast (1), a wishbone (7) and a sail (2) with a mast pocket (3). In the neutral state of the profiled sail, that is when there is no wind pressure, the mast pocket (3) pushed over the mast (1) is arranged loosely around the mast (1). Here, the mast pocket (3) merges into the sail area (2) at a distance from the mast (1) along the transition line (6). Several batten pockets (4) are arranged horizontally in the sail (2). In an extension of the batten pockets (4), reinforcing loops (9) which project into the mast pocket (3) are fastened to the transition line (6). Accommodated therein are sail battens (5) which project with their front edge into the mast pocket (3) up to about the mast. Inside the mast pocket (3), reinforcing inserts (8) are arranged in the area of the sail battens (5). The reinforcing inserts (8) keep the mast pocket open to the outside and give it a tear-shaped profile. During the action of wind, the sail is arched outwards and the mast pocket (3) with the reinforcing inserts (8) arranged therein is pulled forwards and laterally on the mast (1). In accordance with the acting wind pressure, the cross-section of the mast pocket is compressed to a narrower extent against the spring force of the reinforcing inserts (8). As a result, the sail battens (5) bear flush on the lee side inside the mast pocket (3). The advantage of the arrangement is that the sail has a fluidically advantageous profile, the lee side having a uniformly curved shape. <IMAGE>

Filed: 1985-07-12
Abstract: A temple end piece for a temple of a spectacle frame comprises an essentially straight first segment extending in the longitudinal direction of the temple, a connecting segment extending downward from the first segment, and a fitting segment intended for resting against the head and/or behind the ear. The elongated fitting segment is borne by the connecting segment and supported by it, whereby this support is accomplished at the longitudinal middle or on the lower end or in the region between the longitudinal middle and the lower end of the fitting segment, so that at least the upper half of the fitting segment protrudes upward to the first segment and can be deflected elastically in the direction toward the connecting segment. The upper end of the fitting segment is connected to the first segment or the connecting segment with the aid of a flexible, elongated element 20, which element will be sufficiently pliable in order to permit of the deflection movement in sufficient measure, but simultaneously to form a bridge between the upper end of the fitting segment and the first segment and/or connecting segment, so that the upper end can formed no hook-like tip and at the same time no hair or similar objects between the first segment and the fitting segment can reach into the space bordered by the fitting segment and connecting segment.
