Title: Tiled stove
Inventor: SCHWARZ FRIDOLIN
IPC: F24B1/28
Filed: 1981-04-16
Abstract: In a tiled stove which is heated by combustion of fuels, the storage insert (7) and the heating device (6) are arranged in separate locations, in particular the heating device (6) is situated in a cellar space (5) below the room (1), in which the storage insert (7) is situated. The storage insert (7) is heated by the hot smoke gas which is generated by the heating device (6) and which flows safely separated from the room air which is circulated in the room (1). Provided to this end in the storage insert (7), in particular in the chamotte core (8), are smoke gas ducts (15 to 19) which are connected on the one hand via a smoke gas line (11) to the heating device (6) and on the other hand via a smoke gas offtake (10) to the chimney. A soiling of the living area during charging of the heating device (6) is thus avoided, it being possible moreover to use an all-purpose burner, as a result of which fuels which it has previously not been possible to use in tiled stoves can be used. <IMAGE>

Title: Information desk
Inventor: HOELL FRIEDRICH
IPC: G09F1/10
Filed: 1981-05-25
Abstract: The invention relates to an information desk which can be assigned to the inwardly pointing side of the glass in a display window or to a transparent surface. Known desks are constructed on an appropriate substructure. The underframe can, however, often detract from the display effect of the window decorations. The aim of this invention is to specify an information desk which can be directly assigned to the inwardly pointing side of the glass in a display window and can be connected to the latter. The solution is based on a wide material angle (1), the diverging limbs of which point towards the reference plane (7), i.e. towards the inside of the display window. The upwardly pointing limb (4) is equipped with a fastening flange (5), while the downwardly pointing limb (3), the inwardly pointing surface of which forms the desk support, opens out into a supporting edge (3') which points towards the display window. The supporting edge is preferably made to form a pocket for insertion of information material by folding over the material. It goes without saying that other articles can be deposited on the desk surface as well. The inclined desk surface attracts greater attention and therefore heightens the display effect. <IMAGE>

Title: Press for ceramic moulded parts
Inventor: JUNG ROLF DIPL ING
IPC: B30B15/04
Filed: 1981-09-09
Abstract: In the case of a press for ceramic moulded parts, longitudinal deformation and deflection of the columns which act as guides for the pressure rams and/or the pressure ram supports are to be avoided. Jamming of the column guide and/or the points of friction with the columns is not to occur as pressure is applied, which is intended to improve the dimensional accuracy of the parts to be pressed. This object is achieved, as Figure 1 shows, in that tubes (3), which are circular in cross-section, are placed between the two supports (1, 2) of the pressure rams to act as spacers and have, in a slidable fashion on their external circumferences, guides (7, 7a, 8, 8a, 9, 9a) of the reception plates (12, 13) or the like of the pressure rams (15, 17) and through the inside of which there are guided at a distance from the inside wall of each tube (3) the columns (4) which connect the supports (1, 2) to one another and act as prestressed tie elements which brace the supports (1, 2) with respect to one another.   <IMAGE>

Title: Method and circuit arrangement for transmitting signals between any control devices of a clock-controlled highway system which is operated as a function of direction
Inventor: BITZINGER RUDOLF DIPL ING
IPC: H04L12/52
Filed: 1981-09-15
Abstract: In the case of a method and a circuit arrangement for transmitting signals between any control devices via a clock-controlled highway system which is operated as a function of direction, it is provided that an enable signal (F) which switches the control devices into a transmitting state is in each case transmitted via the highway system (CB) from control device to control device. Before the enable signal is passed on from the respective control device, an information signal which is to be transmitted by this control device is emitted together with a receiving address to the highway system, to be precise in conjunction with the relevant control device via the highway system before signals which are possibly supplied before the relevant enable signal. In a control device which is designated by a receiving address, this receiving address is accepted with its information signal for further processing and is replaced by an acknowledgement signal which is to be passed on via the highway system. In the control devices from which in each case one information signal has been transmitted together with a receiving address to the highway system, of the signals which are supplied subsequently to it and consist of acknowledgement signals and information signals, only that signal which is in each case first is accepted for evaluation. <IMAGE>
Patent DE-3142350-A1 (DE)
Title: Firearm
Inventor: PACINER RUDOLF
IPC: F41A3/44
Filed: 1981-10-26
Abstract: A firearm has a breech which is actuable by the firing operation for the cartridge change and which is made essentially in two parts with a breech slide and a breech piece. As a drive for the return movement of the breech slide, some of the gas pressure is transmitted from inside the barrel to a piston and from this to a release and take-up element for the breech slide. Between the breech slide and the grip piece or suchlike housing is a first lock and between the barrel and the breech piece a second lock which are released in succession during the return of the breech slide. The connection between the barrel and the breech piece is released only approximately in the rear stop position of the breech slide which during its return movement, also stores by means of tension springs the energy necessary for the subsequent return of the breech piece. After the shot has been fired, the breech slide and breech piece jointly return to their initial positions and are locked there.

Title: Plug-in fuse having a hollow insulating flat housing
Inventor: SIEPER HEINZ-HELMUT
IPC: H01H85/30
Filed: 1981-11-27
Abstract: The invention relates to a plug-in fuse having a hollow insulating flat housing, from which at the bottom flat contact tongues project whose sections which plug into the flat housing are connected to one another via a fusing conductor. Plug-in fuses of the aforementioned type are used mainly as apparatus fuses, the insulating flat housing generally being manufactured from plastic. However, in this case the disadvantage must be accepted that plastic is not very resistant to heat. The invention is based on the object of improving a plug-in fuse to the effect that it is possible to observe and examine visually the live parts which are surrounded by the housing, even when using a heat-resistant, especially ceramic, material for the insulating flat housing. This object is achieved according to the invention in that the flat housing has an opening on its upper narrow side, below which opening the fusing conductor is located at least partially in a clearly visible manner, and in that a covering part for the exposed region of the fusing conductor can be fitted to the flat housing.

Title: Time-delay electronic device for apparatuses which can be switched on and off with a variable delay
Inventor: KRAUSE MANFRED ING GRAD
IPC: H01H47/18
Filed: 1981-12-01
Abstract: The invention relates to a time-delay electronic device for apparatuses which are intended to be switched on and off with a variable delay, in which an RC element, which controls a control relay or the like for switching operations via electronic switching elements, determines the switching-on delay, and the switching-off delay is provided by the discharge of voltage-supporting buffer capacitors on the input side. In order that the delay times can be maintained in a defined manner irrespective of the load to be switched, and disturbances as a result of interferences with switching times of diagnostic and voltage monitoring apparatuses cannot occur, it is proposed according to the invention that, two trigger stages (14, 15) are used, one of which is connected to the control relay (5) as an output trigger stage (15) and can be controlled by the other trigger stage (input trigger stage 14) via the charge state of a capacitor (18) with separate charging (19) and discharging (20) circuits. Advantage: the invention allows a required drop-out delay to be maintained very precisely. The previously required bandwidth of the switch-off delay can be reduced. <IMAGE>

Title: Method of resistance flash-butt welding
Inventor: KUCUK-YATSENKO SERGEI IVANOVIC
IPC: B23K11/24
Filed: 1981-12-15
Abstract: During the welding of two pieces, these pieces are moved continuously towards one another at the same time as the flashing of their end faces under the action of alternating current, in the course of which an oscillating movement along the feed direction is imparted to one of the pieces to be welded so that the pieces are additionally moved towards one another and away from one another, as a result of which the spark distance as well as the resistance of the contact points of the pieces are changed. If the resistance of the contact points exceeds the preset value, the welding voltage is reduced to 0.7-0 of its operating value and is increased to the initial value again after the drop in the resistance of the contact points below their preset value. The voltage can also be decreased at a time interval of at least 1/8th of the period of oscillation while the pieces are moving apart and can be increased again at a time interval of at most 1/8th of the period of oscillation while the pieces are approaching one another.

Title: Circuit arrangement for controlling dissolving in slide projectors
Inventor: ENTRESS HERMANN
IPC: G03B23/18
Filed: 1982-01-23
Abstract: A circuit arrangement for controlling dissolving in slide projectors is described, the lamp brightness of the projectors being alternately variable as a function of a control voltage, which can be adjusted by means of a potentiometer, through the use of a known circuit arrangement for dissolving. Switching contacts (2, 3) are arranged at both ends of the actuator travel of the potentiometer (1), and each switching contact is assigned a specific transport pulse generator (10 and 11 respectively) for a specific projector. By alternately enabling gates (8, 9) after each transport pulse by means of a flip-flop (13) it is achieved that the transport pulse generators can be driven only alternately. As a result, it is guaranteed that dissolving and change of slide can be undertaken by forward or reverse transport of the slide magazines without the sequence of the slides to be projected being altered once it has been fixed. <IMAGE>

Title: Machine for insulating electrical conductors
Inventor: HELD HANS
IPC: H01B13/16
Filed: 1982-05-22
Abstract: A machine for insulating electrical conductors (2) consists of a feed device (1), a plurality of glass fibre encompassing machines (6), a plurality of enamel impregnation devices (4, 9, 10), a plurality of drying ovens (5, 11), deflection wheels (13, 14) which effect multiple transportation of the conductors through some of the drying ovens (11), a drive device (15) and a coiling device (25) for the complete conductor. The opening of the drying ovens, which is required when the machine is stationary, leads to shrinkage of the conductor, which is compensated for by displacement of some of the deflection wheels. A buffer device (31) acts on the axis (12) of these displaceable deflection wheels (13). The feed device is blocked during the opening of the drying ovens. Before further operation of the machine, the displaced deflection wheels are moved back to their original position again. For this purpose, the rotation direction of the drive device is reversed. The conductor material required for this purpose is obtained by rotating the coiling device backwards. <IMAGE>
