Title: Air outlet
Inventor: MUELLER GOTTFRIED
IPC: F24F13/075
Filed: 1981-02-05
Abstract: The invention relates to an air outlet which consists of a hollow body (10) in the form of a half-shell, which is inserted into a ceiling aperture or wall aperture and is symmetrical relative to the axis of this ceiling aperture or wall aperture and which has a plurality of lateral orifices (12) for the outflow of air. In order to make the incoming air blown into the room by way of the air outlet individually adjustable in a simple way, without reducing the outflow cross-section of the orifices (12), inserts (14) having obliquely set air-deflecting slats (22) are provided in the orifices (12). The inserts (14) are rotatable in the orifices (12), so that the blowing-in direction determined by the air-deflecting slats (22) can be varied. <IMAGE>

Title: Coffee maker
Inventor: FLORJANCIC PETER
IPC: A47J31/057
Filed: 1981-02-09
Abstract: A coffee maker consists of a removable filter vessel, a water container which heats water and delivers it into the filter vessel via an overflow and a resting plate for a coffee jug. The water container is made up of two compartments which form between them a recess into which the filter vessel fits which is partially surrounded by said compartments. The resting plate in the foot of the rear wall bearing the water container is mounted pivotably thereon and can be folded away into the position of non-use. A very small construction depth of the machine is thus achieved. <IMAGE>

Abstract: This circuit arrangement comprises a multivibrator consisting of an inverting amplifier to which an integration capacitor is connected and a non-inverting Schmitt trigger. The signal to be measured (V0) is supplied to a square-wave converter (V1). The output of the square-wave converter (V1) is connected to the input of the inverting amplifier (A1) via a resistor (R1). The output of the Schmitt trigger (ST) is also connected via a resistor (R2) to the input of the inverting amplifier (A1), the output of which is connected to the input of the Schmitt trigger (ST). The output of the square-wave converter (V1) and that of the Schmitt trigger (ST) are connected to the inputs of a multiplier (M) which outputs a signal (U3) proportional to the frequency deviation to be measured. <IMAGE>

Patent DE-3133210-A1 (DE)
Title: Incandescent lamp
IPC: H01K1/46
Filed: 1981-02-26
Abstract: The invention relates to an incandescent lamp having a screw cap. Such incandescent lamps are produced in a known manner in large quantities, although, until now, it has not been possible to achieve exact alignment in a luminaire, especially in a luminaire having a hollow mirror reflector. In order nevertheless to be able to arrange such an incandescent lamp in a defined manner in a luminaire, it is proposed that the screw cap be screwed into a retaining body which has an internal thread and an axial stop surface, and that the luminaire body be at a predetermined distance from the stop surface, in the direction of the longitudinal axis. The said stop surface can thus be engaged in a simple manner with an associated surface of a luminaire, so that the luminaire body now also is aligned in a defined manner to the luminaire. The method for producing an incandescent lamp with a retaining body is preferably carried out in such a manner that the screw cap of the incandescent lamp screwed into the internal thread in the retaining body until the luminaire body is at a predetermined distance from the stop surface of the retaining body. <IMAGE>

Title: Annular diaphragm valve
Inventor: BRAMKAMP-MANTEY GEB BRAMKAMP
IPC: G05D23/12
Filed: 1981-11-11
Abstract: A valve body designed as an annular diaphragm and having an upstream measuring part is used in pipes which bring a medium into or as far as high-temperature zones, the space surrounding the annular diaphragm and the measuring part being connected to one another via a connector which carries a control medium. If the pipe surrounded by the measuring part, which is designed as a hollow body, is subjected to excessive thermal stresses, the annular diaphragm is acted upon by the expanding control medium and acts on the auxiliary body seated in the feedpipe, the feedpipe thereby being closed. A non-return plate is arranged at a certain distance in front of the diaphragm in order to safeguard it. <IMAGE>

Patent DE-3207319-A1 (DE)
Title: Recorder
Inventor: GRUNWALD KLAUS
IPC: G10D7/02
Filed: 1982-03-01
Abstract: This recorder consists of a mouthpiece (10), a barrel (12) and a bell (14) attached to the barrel (12). The internal width of the barrel (12) and of the mouthpiece is approximately one and a half times to twice as great in comparison with conventional recorders of the same pitch. The finger holes (24 to 38) provided in the barrel (12) have a diameter which is approximately twice as great as the finger holes of comparable recorders. Because of the greater internal width of the barrel (12) and the attached bell (14), very good richness of tone in low notes is achieved combined with good richness of tone in higher notes. The finger hole (38) is provided with an attachment (40), as a result of which it is possible to keep the distance between the finger hole (36) and the finger hole (38) short. As a result, a key mechanism for the finger hole (38) may be omitted. <IMAGE>

Title: Housing frame for an operating apparatus
Inventor: SCHMIDT EVAMARIA
IPC: F16M11/04
Filed: 1982-03-06
Abstract: A housing frame exists having a hinge device (14) on which a rod (22) is fitted which is used for fitting the operating apparatus and as a handle. In this case, it is desired that the rod be supported in a secured manner on the hinge device against being pulled off at right angles to the rod and that it nevertheless be easily adjustable in height. This is achieved in that an essentially vertically running screw spindle (12) is provided such that it can be screwed on the upper end piece of the stand (1), the upwardly projecting end of which screw spindle supports the hinge device (14), and in that the hinge device (14) comprises a first hinge piece (16) which is supported at the end of the screw spindle (12) such that it can rotate about an essentially vertical axis, and on which a second hinge piece (17) is supported such that it can rotate about an essentially horizontal axis (18), which second hinge piece supports a sleeve (19) which holds the rod (22) such that it can be displaced and fixed (24). In this housing frame, the height of the hinge device (14) is adjusted by rotating the spindle (12). <IMAGE>
