If a further drive source is also provided, the nut can be designed as a releasable coupling.
Patent DE-3807213-A1 (DE)
Title: Hi-hat
Inventor: BAERSCH HERMANN
IPC: G10D13/06
Filed: 1988-03-02
Abstract: In contrast to a conventional hi-hat (1), this one has two foot pedals (2, 4) which are fastened movably on a pin with a rigid extended support (3). The shortened pedal is fastened, by means of band, belt or chain (5), running via rollers or pinions (6, 7, 8), to the foot pedal holding device (9). By means of alternately depressing the pedals with point of the foot and heel, including the adjusting screw (10), a so-called rocking effect is produced which brings about a double closing of the cymbals (11), i.e. a double beat. Consequently, the skilled drummer goes at a crazy speed, which, with the single-pedal hi-hat, was only possible, if at all, with very great exertions. By means of a hook or screw device, the shortened pedal can be disconnected at once when it is not required (12). <IMAGE>
Patent DE-3811419-A1 (DE)
Title: Device for the automatic triggering of a room ventilator (fan or blower) when the relative room humidity approaches the respective dew point
Inventor: WENZ ZU NIEDERLAHNSTEIN VOLKER
IPC: G05D22/00
Filed: 1988-04-05
Abstract: A sensor (1) let into the (outer) masonry (MW) of a room from the side with the higher temperature (HT) forms a heat-conducting bridge to the side with the lower temperature (NT). As a result of this, a humidity detector (2) fitted onto the inner end (3) of the sensor (1) in intimate thermally conductive contact reaches a temperature which is a few degrees lower than the side with a higher temperature (HT) of the adjacent masonry. If the humidity of the room air approaches a critical value, a condensate is deposited on the humidity detector (2) before it comes into contact with the masonry. The condensate produces a changed electrical signal (e.g. change of resistance of the humidity detector). An electrical circuit performs, in a known manner, the relay function and switches on a room ventilator. When the condensate disappears, the relay function switches the ventilator off again. <IMAGE>
Patent DE-3812818-A1 (DE)
Title: Pressure regulator with protective diaphragm against icing of the regulator diaphragm
Inventor: GOTTFRIED JOSEF DIPL ING
IPC: G05D16/06
Filed: 1988-04-16
Abstract: In the expansion of a gas, especially here in liquid-gas pressure regulators, a severe drop in temperature occurs which, especially at external temperatures around freezing point, affects the pressure regulator unfavourably in respect of the formation of water of condensation above the regulator diaphragm from the breathing air and, inside the gas input union, from water vapour in the gas phase. If this condensate freezes, the ice formation leads to disturbances in the regulator function and thus in the gas supply. A protective diaphragm with a safety device allows gas blowing out of the diaphragm safety valve to be led away into the atmosphere and the diaphragm space still to be kept free from moist atmospheric air. An additional emergency feed-in device for supplying gas out of a substitute container in the event of failure of the gas supply because of icing of the gas input union is also the subject-matter of the invention.
Patent DE-3814016-A1 (DE)
Title: Plug having electrical components
Inventor: BARKOW HELMUT
IPC: H01R13/66
Filed: 1988-04-26
Abstract: It is intended to provide for accommodating electrical components, the individual parts of which plug can be produced easily and whose assembly can be carried out by means of automatic processes. Sprung individual contact pieces which are constructed in the form of forks are firmly embedded in pairs in an insulating plastic housing, at a rigidly predetermined distance apart. The individual contact pieces are constructed at the sprung fork ends such that a stationary contact pin is gripped with sufficient contact pressure. The other ends of the individual contact pieces have a notch for accommodating the connections of an electrical component. Using the plug, which can be produced largely by means of automatic processes, for the accommodation of electrical components, it is possible in a particularly simple manner to loop electrical components into a cable connection, for example in the case of main distributors in telephone exchanges.
Patent DE-3817176-A1 (DE)
Title: Automatic tensioning device
Inventor: BRANDENSTEIN MANFRED
IPC: F16H7/08
Filed: 1988-05-20
Abstract: Arranged between the tensioning spring 11 and the swivel arm 2 of the tensioning pulley 4 in an automatic tensioning device is a pressure-wedge mechanism 5, 8 with gently sloping wedge faces 6 that effects a step-up in the force of the tensioning spring 11 acting on the pressure wedge 5. The tensioning spring 11 is produced from memorious metal with a reversible step-change characteristic, for example, and, as a result, little or no tensioning force is exerted on the driving belt in the cold phase of the engine and a large tensioning force is exerted on it in the warm phase, in operation. The movement of the pressure wedge 5 is very greatly damped so that only those changes in the driving belt which represent a long-term trend are compensated. The tensioning device adapts to the existing conditions of the driving belt, of the inputs and outputs and of the engine each time the engine is started cold. <IMAGE>
Patent DE-3829569-A1 (DE)
Title: Vacuum cleaner nozzle for vacuum cleaners with returned exhaust air
Inventor: PFEIFFER ALFRED
IPC: A47L9/08
Filed: 1988-08-31
Abstract: The vacuum cleaner described in German Patent 3739050 C1 with return of the filtered exhaust air is equipped with guide wheels, which are expensive to manufacture and store. Subsequently, a vacuum cleaner was proposed by German Patent 3422178 C1 having a nozzle in which the movable parts are dispensed with. As a supplement to this, a nozzle which ensures a considerably improved vacuuming of the floor surface is proposed for the vacuum cleaner. As a result of the swirling air current produced directly at the lower edge of the nozzle, the loosened floor dust is sucked up by the large suction opening and air is thus unable to penetrate outwards. Even when the nozzle is lifted off the floor and where there is a space between the nozzle and uneven surfaces and/or curves, the latter are freed from fine dust.

Patent DE-3907243-A1 (DE)
Title: Ship structure with the greatest possible weight saving
Inventor: BADURA GERHARD PIZ DR ING
IPC: B63B3/00
Filed: 1989-03-07
Abstract: Floating ship structures of bamboo, timber, aluminium, plastics and steel are known. The construction system described here concerns in the initial situation a steel hull. Events show time after time that passenger ships, merchant ships, container ships and warships are inadequate in the hull construction to protect against damage despite considerable wall thicknesses of even more than half a metre and corresponding dead weights. Further wall strengthening automatically entails increased dead weights, relatively reduced useful-load options, increased expenditure of energy at still inadequate speeds. The aim of the invention is to use in combination with steel a synthetic material which is already obtainable on the market and which has a rupturing strength comparable with that of steel but is substantially lighter than steel in weight by volume. Since this synthetic material does not enter into a connection with steel in this order of magnitude, the hull is welded together three-dimensionally in terms of laminations and horizontally and vertically in terms of hollow spaces, so that the hollow spaces thereby developed can be lined with the synthetic material. According to the invention, the description relates to the arrangement of the hull construction of any requisite wall thicknesses which is welded together three-dimensionally in terms of laminations and horizontally and vertically in terms of hollow spaces and recessed and offset in the lamination thickness. <IMAGE>
Patent DE-3909680-A1 (DE)
Title: Device to generate curved surfaces
Inventor: ITABA TETSU
IPC: G05B19/4097
Filed: 1989-03-23
Abstract: The invention concerns a device to generate a curved surface, using input data which represent a large number of curves to generate a curved surface (A) in a CAD/CAM system or an automatic programming device. The device to generate curved surfaces according to the invention has means to rearrange the definition data (C1 to C4) of the curve form, and the arrangement position data (P1 to P4), automatically. The operator can therefore define a curved surface using the device without taking into account the arrangement sequence of the curves. Accordingly, the device is easy to operate. For the same reason, there are also no wrong operating sequences or wrong data inputs when using the device. <IMAGE>
