Title: Electrically reinforced twin-pedal machine for drummers
Inventor: ROTH MICHAEL
IPC: G10D13/00
Filed: 1982-02-15
Abstract: The invention serves to relieve the drummer of the necessity to overcome the restoring force of the restoring spring of the drumstick. The latter now has only to actuate a clutch. The invention also serves to increase the frequency of drum beats, since the possibility now exists of using one foot to actuate two drumsticks alternately, simultaneously or with any desired offset.
Patent DE-3206676-A1 (DE)
Title: Profiled rail
Inventor: BAUS HEINZ GEORG
IPC: A47K3/30
Filed: 1982-02-25
Abstract: The invention relates to a profiled rail, especially for a frame or door element or wall element of a shower partition wall, having a screw duct which has an opening extending in the longitudinal direction. A screw or the like can be inserted into such a screw duct in order to produce a connection to another profiled rail or other components. Until now, it has been attempted to keep the opening which extends in the longitudinal direction of the screw duct as small as possible in order to prevent the screw breaking out or, in addition, to prevent oblique insertion of a screw. On the other hand, during production, especially during anodising of such a profiled rail with a largely closed screw duct, difficulties arise particularly since acid residues and paint residues can stick there. Furthermore, the pressing tools required for this purpose are highly expensive to produce, the service lives achieved today often not satisfying the operating requirements. It is therefore proposed according to the invention that the opening in the screw duct have an insertion element allocated to it, at least at the ends of the profiled rails, the opening preferably being closed, and that the insertion element engage with the outer surface of the screw duct and/or with other parts, especially the side walls, of the profiled rail. <IMAGE>

Title: Process for the treatment of water-containing condensate from the cooling of the crude gas of coal pressure gasification
Inventor: BECKER PAUL DIETER DR
IPC: C10J3/84
Filed: 1982-03-04
Abstract: Crude gas from the gasification of solid fuels is cooled in a plurality of cooling steps. In this way, condensate is obtained having a temperature of at least 130 DEG C and a pressure of at least 4 bar. This condensate is flashed and the flash vapor thereby produced is burned. The flashed condensate is fed to a separating device from which a condensate phase consisting predominantly of water (gas liquor) is withdrawn. The gas liquor is cooled in direct contact with colder gas before it is used for the cooling of the crude gas. The heated water-vapour-containing cooling gas is fed for combustion. Generally, the gas liquor is cooled in direct contact with the colder gas to a temperature of about 30-90 DEG C. The cooling gas expediently consists primarily of one or more of the gases carbon dioxide, nitrogen, methane or carbon monoxide.

Title: Narrow-gauge film cassette
Inventor: POETTER BERNHARD
IPC: G03B17/26
Filed: 1982-06-30
Abstract: A rotary wind-off bobbin (5) and a rotary wind-up bobbin (13) are mounted on both sides of a partition (2) in the cassette housing (1) of a narrow-gauge film cassette. The wind-off bobbin (5) and the wind-up bobbin (13) are each provided with latching teeth (25, 27), which project relative to the plane of the partition (2) and engage with latching projections (24, 26) on click-stop detents (22, 23) and in each case form a non-reverse ratchet for the wind-off bobbin (5) and the wind-up bobbin (13). The click-stop detents (22, 23) are arranged behind one another in a window (21) of the partition (2) and can be pivoted by a rod (34), which can be actuated from outside, in order to cancel the non-reverse ratchet. The two winding bobbins (5, 13), which can be driven from outside, can then be rotated in the opposite direction of rotation, so that the film accommodated in the narrow-gauge film cassette can be entirely or partially rewound. <IMAGE>
Patent DE-3225479-A1 (DE)
Inventor: WEBER KLAUS DR
IPC: G02B7/16
Filed: 1982-07-08
Abstract: A transmitted-light illuminating device (FIG. 1) for microscopes consists of a condenser (1), an iris-aperture diaphragm (2) and a turret (3). The turret permits interchangeable mounting of auxiliary lenses (4) or diaphragms (5) by means of which large-object fields can be illuminated, if desired; alternatively, the microscope can be used in phase contrast. Condenser, diaphragm and turret are combined into a unit in which the turret is functionally coupled to the iris diaphragm. For this purpose, the index shaft of the turret (3) is eccentrically mounted to the actuating ring (9) of the diaphragm (2), the ring is configurated for detent engagement to retain the newly indexed turret station in axial register with the optical axis of the condenser. Thus, rotation of the turret first drives the actuating ring (9) against its diaphragm stop to thereby open the diaphragm before there is any indexing movement of the turret, from one to its next indexed position.

Patent DE-3314223-A1 (DE)
Title: Rotary lid joint
Inventor: DREUSCHE UDO VON
IPC: E05F1/12
Filed: 1983-04-20
Abstract: In a rotary lid joint, especially for boiler installations, which consists of two bearing blocks to be retained at a fixed location and of a joint part rotatable between them to a limited extent about the joint axis and intended for connection to the lid, for relieving the weight of the lid in opening positions there engages in the rotatable joint part a spring of adjustable prestress, the pressure force of which varies during the opening movement, it is proposed to provide in the rotatable joint part a compression spring which is supported perpendicularly to the joint axis and which presses on to an eccentric pin which is guided on both sides parallel to the joint axis in a slotted guide of the joint part and which engages positively with both ends projecting from the joint part into a respective long-hole guide arranged approximately radially relative to the joint axis, on the bearing blocks, in such a way that, when the joint part is being rotated from the closed position into the opening positions, the spring (6) is compressed to an increasing extent. The eccentric engagement of the compression spring on the rotatable joint part provides a rotary-joint construction which is advantageous in terms of production and assembly and which ensures that, with the lid lowered, the highest spring tension is exerted before the closing region and the lid, when appropriately set in its opening position, is held <<weightlessly>> by the corresponding restoring force. <IMAGE>
