Patent DE-3605235-A1 (DE)
Title: Sweeping machine with at least one circular broom
Inventor: HAAGA HERMANN DIPL ING
IPC: A47L11/22
Filed: 1986-02-19
Abstract: A sweeping machine consists of at least one circular broom which is arranged laterally on the housing, is mounted rotatably about an approximately vertical axis and is provided with a rotary drive. A base plate over which part of the circular broom brushes, is arranged on the underside of the housing of the sweeping machine. The base plate is provided with a stripping element on its surface facing the circular broom. This element is arranged at a distance from the edges of the base plate. Scraps of paper, cigarette ends or the like, which are speared onto the bristles of the circular brooms, are removed again by the stripping element. By arranging the stripping element at a distance from the edges of the base plate, the removed litter is prevented, by the rotation of the circular broom, from being thrown back again onto the surface to be swept and instead is reliably taken up by the sweeping machine.

Title: Automatic soldering device for hard metal teeth
Inventor: GERLING NORBERT
IPC: B23K31/02
Filed: 1986-06-26
Abstract: A device for automatically soldering on hard metal teeth to the prongs of a circular saw blade is described, in which a turntable which has grooves receives a hard metal tooth, transports it under a flux coating station, and subsequently conveys it onward to a solder plate punching and depositing device and to a bending station where the solder plate is bent around the back of the hard metal tooth and subsequently moved into an angular position in which the existing unit is transferred to the solder mount and moved into the soldering position in which a prong of the saw blade is pressed from above against the hard metal tooth and the soldering process is carried out by an inductive high-frequency heater. The saw blade receptacle device has a directly drivable axle which receives the saw blade. In addition, a photoelectric barrier is provided for controlling the saw blade axle drive so that the individual prongs of the saw blade each assume the exact soldering position (Fig. 1). <IMAGE>

Title: Method for reducing compressed-air losses when driving underground, compressed-air-supported cavities and device for carrying out the method
Inventor: PINKERNELL HANS DIPL ING
IPC: E21D9/06
Filed: 1986-06-27
Abstract: The method serves to reduce compressed air losses when driving underground, compressed air-supported cavities. The in-place soil in the extraction space is removed at a heading face. The foot of the heading face is filled with fluid. The part of the heading face remaining above the level of the fluid is covered during advancing with a curtain-like, flexible, at least approximately air-tight diaphragm. As a result of its flexibility, it can adapt continuously to the changing surface of the heading face during the advance and thus ensure satisfactory sealing of the heading face at any time.

Abstract: A device for regulating the dosage of a fluid component in a carrier current medium, for example volatile narcotics in an oxygen carrier current, is to be improved such that the amount to be metered corresponds to the concentration in the narcosis gas, whereby the changes in the properties of the carrier medium are to have no effects on the concentration measurement. For this purpose a reference detection element (3) is provided in the line (2) carrying the carrier medium, which line is connected through a reference signal wire (18) to the control unit (16) designed as a comparator. The actual value for the control unit is formed from the comparison value between the reference signal from the reference detection element (3) and the measurement signal from the detection element (8). <IMAGE>

Abstract: The invention relates to a perforating device which, as well as being suitable for independent use, is clamped into the suspension clips of a letter file and the like and is therefore immediately available whenever perforated sheets of writing paper etc. are to be filed. The perforating device which, in accordance with its region of application, is to some extent smaller than current perforating devices, is provided with a clamping rail, has a curved pressing projection for manual operation of the tapping clip and is furthermore characterised by a mount for accommodating a pencil-like writing implement of any kind. Displacement of all the documents etc. contained in the letter file up to the normal height, for example, from the right to the left half of the letter file can continue to be carried out without difficulty, in so far as despite a slight loss of space caused by the perforating device which is situated on the rear of the letter file in the folded condition, no space is taken up in the clip reception area. Furthermore, perforating operations can also be carried out simply by the exertion of pressure on the bottom lid when the device is in this position.

The differentiator (DZ) is connected to a clock input (CL) of a signal store (FF) and via a first logic gate (G1) to a reset input (R1) of a first delay component (VG1). An output (Q1) of the first delay component (VG1) is fed back via the first logic gate (G1) to its reset input (R1) and is furthermore connected to a reset input (R2) of a second delay component (VG2). An output (Q2) of the second delay component (VG2) is connected to a signal input (D) of the signal store (FF), downstream of whose signal output (QA) a digital low-pass balancing network (TP) is connected. The time constant of the first delay component (VG1) is longer than the cycle duration of the signal with the upper assigned frequency and shorter than the cycle duration of the signal with the lower assigned frequency and the time constant of the second delay component (VG2) is longer than the cycle duration of the signal with the lower assigned frequency. <IMAGE>
