Title: Shut-off device in the waste gas flue of a fireplace
Inventor: KUTZNER LUITPOLD DIPL ING
IPC: F23N3/04
Filed: 1982-10-19
Abstract: A shut-off device in a waste gas flue of a fireplace is proposed, which has a safety device to protect against overheating. The safety device becomes active when the shut-off device is subjected to such overheating that its capacity for functioning could be influenced and has the effect that the shut-off device can no longer close after such overheating. The risk of the shut-off device not opening or opening too late when a fireplace is set in operation is therefore excluded.

Title: Hand tool with two-speed transmission
Inventor: THEISSIG WERNER
IPC: B23B45/00
Filed: 1983-03-28
Abstract: The hand tool, such as a hammer drill and the like, has a mechanically shifted two-speed transmission. The axial displacement, required for shifting the transmission, of a gear block (11) is effected by means of a rotatable shifting element (14) which is connected to a shift fork (12) via a shifting dog (14a) with a shifting gate. The shifting gate and the shifting dog (14a) have supporting surfaces which come into contact in the end positions of the rotation of the shifting elements (14), the supporting surfaces of the shifting gate being arranged in such a way that the surface normal intersects the axis of rotation of the shifting element (14) in the end positions of the rotation of the latter. Unintentional displacement of the shift fork (12) is thus prevented in these end positions. <IMAGE>

Title: Method for determining the braking current for braking an AC motor
Inventor: VOLLMAR WILFRIED ING GRAD
IPC: H02P3/24
Filed: 1983-07-07
Abstract: In the method for determining the r.m.s. value to be set for a braking current in an electronic braking device of an AC motor which drives a tool, it is intended to take into account all parameters which have an influence on the braking current, so that the selection of the braking device, which takes place in accordance with the r.m.s. value of the braking current, is always set optimally in the case of the given tool and motor. To this end, the moment of inertia of the tool and/or of the rotating parts of the motor is determined initially. The required braking power is determined from this, and the arithmetic mean value of the braking current is determined therefrom. The form factor for the braking current in the case of the voltages which are present on the motor and the braking device is determined via the delay angle of a semiconductor switch is operated using phase-gating control and is present in the braking device, and the r.m.s. value of the braking current is determined from the arithmetic mean value of the braking current, using this form factor.

Patent DE-3337088-A1 (DE)
Title: Simple device for driving electronic switches at zero potential
Inventor: BOEHRINGER ANDREAS
IPC: H03K17/691
Filed: 1983-10-12
Abstract: Electronic switches must be driven at zero potential in many applications. For this purpose, either drive circuits with floating power supplies and a signal transmission via optocouplers are currently used (which restricts the immunity from interference) or the switches are driven via in each case a number of transformers. Previously proposed solutions with less complexity always mandatorily require the partial omission of well-defined drive signals, are thus less reliable and restrict the utilisation of the characteristic data of the electronic switches. These disadvantages are avoided in the arrangement according to the invention, shown by way of example in Figure 2. The electronic switch (1) is here driven via a logic and switching unit (2). This is continuously supplied with power by a potential-isolating invertor (5). In addition, the control signals for the switching states of the electronic switch (1) are transmitted via its transformer (4) to the logic and switching unit (2) in that the output voltage, output current or output frequency of the invertor (5) is changed by interventions at its input side (6). In connection with suitable control methods, a very simple and, nevertheless, reliable zero-potential drive for electronic switches is thus produced. <IMAGE>

Title: Housing for hand-held instruments, especially writing instruments
Inventor: NEIGE MANFRED DIPL ING
IPC: B43K23/004
Filed: 1984-02-11
Abstract: In this housing (2), the wall (3) is provided with perforations (4) in the gripping region. On the inside of the wall is a body (5) with movable tongues (7) on which burl-like projections (6) are provided which can be pushed through the perforations. During non-use, the tongues are bent inwards and the projections are within the housing, so that the housing has a smooth, easily cleaned outer surface. When the instrument is used, a switching device actuates a splaying element (9) which presses the tongues against the inside of the wall (3), so that the projections (6) pass through the perforations and project from the housing on the outside. The effect is to produce a burled gripping surface which provides secure and pleasant holding of the instrument. <IMAGE>

Title: Plant for the supply of buildings with hot water and/or for room heating
Inventor: WIEDL ALFRED
IPC: F24D11/02
Filed: 1984-04-13
Abstract: The invention extends to a plant for the supply of buildings with hot water and/or for room heating with useful heat recovered from the ambient air by means of a heat pump which can be driven by a combustion diesel or gas engine. The most essential characteristic of this newly developed plant consists of the combination of a large-volume and high, in relation to its cross-section, buffer reservoir in the heating medium circuit of a heat transfer medium which can be caused to circulate by two selectably connectable circulating pumps and two three-way valves with reversible forwarding direction, and the installation of a flow damper at the upper connection point for the heat transfer medium to the buffer reservoir and also of a heat sensor near the upper connection point which controls the two circulating pumps and at the same time serves to set the combustion engine in operation, while a second heat sensor serving to shut off the combustion engine is arranged near to the lower connection point of the buffer reservoir. The constructional design of the flow damper and of the air heat exchanger and also the arrangement of a centrifugal clutch between the combustion engine and the compressor of the heat pump form further features of the invention.
