Title: Apparatus for the suspension of a spray system
Inventor: KAFITZ WALTER
IPC: B03C3/70
Filed: 1983-03-09
Abstract: The invention relates to an apparatus for the suspension of a spray system of a vertical electrostatic precipitator, with a support column (16) passing through an opening (18) of a housing roof (4). The support column (16) also forms the current supply for the spray system with an electrode frame (10) and is carried on the housing roof (4) by means of an insulator. Lead-in insulators were hitherto used which above all were very greatly endangered by bending stresses. Furthermore, coverings on such insulators could cause damage to them. It is therefore proposed that only a single support column (16) is passed through a single opening (18) of the housing roof (4). Furthermore, the support column (16) is fastened at the upper end to a beam (20) which rests on at least two support insulators (22) arranged on the housing roof (4). Finally, the electrode frame (10) is connected to the single support column (16). <IMAGE>

As a result of this arrangement, the coins are stored in succession and also in juxtaposed manner. The insertion and dispensing of coins takes place by a corresponding controlled rotation of the impeller, the rotation for insertion taking place in one direction and that for dispensing in the other direction.
Patent DE-3323069-A1 (DE)
Title: Propellant charge with axial-force compensation
Inventor: BONGERS HERMANN DIPL ING
IPC: F42B5/16
Filed: 1983-06-27
Abstract: In the known recoilless weapons, the casing of the propellant charge is pressed against the inner wall of the charge space by the gas pressure occurring during the burn-up of the propellant charge occurring when the weapon is fired. If the propellant-charge casing is torn off in an uncontrolled manner, an undesirable recoil can thereby be transmitted to the launching device. The avoidance or reduction of the recoil is achieved, according to the invention, in that the casing of the propellant charge is kept smaller in diameter than the charge space, in that the charge space is sealed off at the front and rear by closing covers, and in that the closing covers are mutually supported in the axial direction by means of one or more connecting elements. In a further embodiment of the invention, the two closing covers are omitted. In this version, the charge space is sealed off at the rear by a heavy metal-powder tamping (counter-projectile) and at the front by the projectile. The connecting elements are fastened directly to the projectile and to the tamping. <IMAGE>

Title: Electronic switched-mode power supply having a reactor converter
Inventor: HEUWINKEL LOTHAR
IPC: H02M3/156
Filed: 1983-09-24
Abstract: In order to supply an electrical load from an input voltage source of variable or varying voltage magnitude and/or frequency, an electronic switched-mode power supply having a reactor converter is provided, in which the switching path of a switching transistor is connected in series with a reactor and a first resistor, the base of which switching transistor is connected both to a circuit, which is connected to the electrical load, for regulating the output voltage and, via an auxiliary inductor which is magnetically coupled to a reactor, to the reactor. During the phase when the switching transistor is switched off, the energy which is stored in the reactor during the phase when said transistor is switched on is discharged into the electrical load via a first diode, or a store which is connected in parallel with the electrical load. In this case, the first diode may optionally be connected to a winding tap of the reactor, to the winding end of the auxiliary reactor which is connected to the base of the switching transistor, or to the winding end of the reactor which is connected to earth or reference potential.

Patent DE-3404151-A1 (DE)
Title: Signalling device
Inventor: ZIERHUT HERMANN DIPL ING
IPC: G08B13/19
Filed: 1984-02-07
Abstract: The invention proceeds from a signalling device for monitoring a space for temperature changes, which consists of a radiation receptor, which has at least one detector with at least one sensor that receives the electromagnetic radiation and an integrated field-effect transistor, as well as a downstream linear amplifier and means for compensating the frequency response of the sensor output level, an evaluation circuit for triggering an alarm in the event of a change in radiation intensity, and an alarm unit. In order to improve the signal-to-noise ratio and thus the noise immunity in as simple and cost effective a way as possible, the field-effect transistor is co-used as an active subassembly of an equaliser amplifier connected to the sensor. For the purpose of complete compensation of the drop in output level of the sensor in the direction of higher frequencies, in the case of devices with a large range and thus a large bandwidth it is proposed for the equaliser amplifier to be designed with at least two stages, the slopping position of the gain being effected, on the one hand, by a frequency-dependent negative feedback between the two stages and, on the other hand, by a series RC element between the emitter of the transistor of the second stage and the positive pole of the feed voltage source.

Patent DE-3409175-A1 (DE)
Title: Device for determining the components of wind velocity
Inventor: REISCH MICHAEL
IPC: F02B3/06
Filed: 1984-03-13
Abstract: The wind velocity is determined by determining the transit times of an ultrasonic pulse from a transmitter to a suitably selected arrangement of receivers. If the transmitter is denoted by S, the receivers by Ei, the lengths of the paths SEi by Li, the associated transit times by Ti and the unit vectors of S in the direction of Ei by ni, the relationships <IMAGE> are valid, where w represents the vector of the wind velocity. Interpreting c and w as unknowns, the determination of w requires three transit time measurements in the case of planar flow, and four transit time measurements along different transit time paths in the case of three degrees of freedom for w. The result of these transit time measurements is used to determine w with the aid of a computer.

Title: Tool holder for an electropneumatically operated hammer drill
Inventor: GEIS WILHELM DIPL ING
IPC: B25D17/08
Filed: 1984-03-15
Abstract: The invention relates to a tool holder for an electropneumatically operated hammer drill, which contains a self-centring chuck which is mounted on the drill spindle sleeve and receives normal drills. Known tool holders of this type are relatively complicated since they comprise or require two mutually independent holder systems for normal drills and hammer drills. Also, the holder system for the hammer drills allows only a drill shank having a quite specific diameter, for example 10 mm, to be used. If the diameter of the drill spiral is smaller than that of the shank an additional expenditure on material has to be accepted, which increases the cost of the drills. The object of the invention is to provide a tool holder with a combined holder system for normal drills and hammer drills that is not governed by the shank diameter of the drills and allows cheap hammer drills to be used while fully utilising the available impact energy from the drive. This object is achieved according to the invention if a set collar engaging with a sleeve is rotatably arranged on the chuck body of the self-centring chuck and the sleeve has, on its internal circumference in its end region on the snap-side, at least one recess for radial escape of the spherical locking member, and if the self-centring chuck in the position locking the ...

Title: Frame for door and window leaves provided with a panel-shaped filling
Inventor: SAELZER HEINRICH
IPC: E06B3/58
Filed: 1984-05-24
Abstract: Frame legs, which are interconnected via corner angles, are formed from U-shaped hollow profiles (1). To receive the corner angle legs (13), the hollow profile (1) has an undercut groove (12) which is open towards the frame interior. In each corner angle leg (13), at least one threaded bore (15) is arranged in such a manner that a threaded bolt (14) can be screwed into the latter from the frame interior in an unhindered manner, which bolt is pressed with a bolt tip (16) into the bottom of the groove (12). The threaded bolt (14), which preferably consists of a headless screw, raises the corner angle leg (13) from the bottom of the groove (12) and presses it against the groove inner side lying opposite the bottom. The arrangement of the groove (12) in the region of the profile web which is adjacent to the edge strip (5) of the filling (6) leaves inside the hollow profile (1) sufficient space for accommodating further components which, similarly to the corner angle legs (13), can be inserted into comparably designed undercut grooves (17, 22). <IMAGE>
