Title: Push-in barrel for firearms having a large-calibre barrel for firing mostly small-calibre live cartridges
Inventor: DUSILEK RUDOLF
IPC: F41A21/10
Filed: 1984-04-14
Abstract: The object of the invention is to make it possible, for a firearm (hunting weapon) having a mostly smooth shot barrel, to use a mostly small-calibre bullet barrel, in order to satisfy the present-day (limited) hunting possibilities with a live or delayed-action cartridge corresponding to the game or vermin to be hunted. The push-in barrel is adjusted to the barrel length of the parent weapon (shot-barrel length). It does not project and is flush with the parent weapon at the barrel nozzle. There are therefore no external visible variations or mountings, such as, for example, in German Utility Model 8000250.

Patent DE-3432266-A1 (DE)
Title: Electronic ballast for fluorescent lamps, and a method for its operation
Inventor: WERFELI FRIEDRICH
IPC: H05B41/298
Filed: 1984-09-01
Abstract: By means of signals from a monitoring device, which has a starting monitoring circuit (9) and an operation monitoring circuit (10) for the fluorescent lamps, as well as a temperature monitoring circuit (11) for the invertor, the control device (12, 13) which controls the invertor in terms of frequency can be brought to an initial position. The initial position is assumed when the monitoring device reports that no lamp can be operated, for example because there are no lamps or the temperature of the invertor is too high. The starting process for the lamps is initiated from the initial position in the event of second status reports from the monitoring device, which indicate that lamps have been replaced. If, in addition, only one of a plurality of lamps starts, the operation is started at the burning frequency. In consequence, the apparatus is always in a defined operating state, regular starting attempts for deactivated lamps are avoided and, when lamps are replaced, they start without further measures, for example replacement of a fuse or switching off the mains voltage. <IMAGE>

Title: Method and device for controlling the foam formation in tank-type washing machines, in particular disinfectant dishwashers
Inventor: BIERMAIER HANS
IPC: B08B3/00
Filed: 1984-11-08
Abstract: To control the foam formation in tank-type washing machines, in particular disinfectant dishwashers, the water pressure of the water circulated by a circulating pump (11) is determined by a pressure sensor (22) or by power measurement (22') of the power consumed by the circulating pump (11). The temperature ( theta ) of the circulated water is furthermore measured by a temperature sensor (14). If the measured pressure (P1) falls below a specified pressure value and if the measured temperature ( theta ) is above a specified value at the same time, the heating power is reduced. If, on the other hand, the measured temperature is below the specified value during this pressure drop, a feed pump (20) for defoaming agent is activated by means of a control logic (24). The pressure built up in the pressure line (21) of the feed pump (20) is also measured by a pressure sensor (23) to monitor whether the feed pump (20) is pumping correctly. Preferably, an obstacle to flow, for example in the form of a metering orifice or pipe narrowing is fitted downstream of the pressure sensors (22, 23). <IMAGE>

Title: Hydraulic pressure cylinder
Inventor: HARTMANN WILLI
IPC: B60T11/20
Filed: 1985-01-19
Abstract: The tandem main cylinder is used for a hydraulic brake system of motor vehicles and has a cylinder housing (1) in whose cylinder bore (2) two pistons (3, 4) arranged one behind the other are guided in an axially displaceable manner. A piston spring (18) held with pretension by a captive arrangement (14) is formed in the cylinder space (10). The piston spring (18) bears on the primary piston (3) and on the secondary piston (4) in the initial position of the tandem main cylinder. The captive arrangement (14) consists of a fastening element (27) which is guided on the primary piston (3), projects into the cylinder space (10) and makes the connection to the piston spring (18) via the sleeves (24, 20). The axial overall length of the tandem main cylinder can be reduced on account of the telescoping of the first sleeve (24) in the second sleeve (20). A further reduction in the overall length of the tandem main cylinder is obtained by a further design of a captive arrangement with two further sleeves in the cylinder space (12). <IMAGE>

Title: Roll-changing device
Inventor: BENZ WILLI
IPC: B21B13/00
Filed: 1985-05-02
Abstract: Known roll-changing devices cannot be operated fully automatically and thus do not significantly reduce the cost factor because the interruptions to production are too long. The present invention presents a roll-changing device for roll rings seated on horizontal or vertical rolls, consisting essentially of a rotary column (4) with a side arm (5) on which is situated at least one roll take-up device (7, 8), each roll take-up device (7, 8) having a clamping head (16, 17) which can be moved in the longitudinal direction of the roll by actuating means (26, 27, 28, 29) and which can be connected to a respective changing head (10, 11) with an integrated roll ring (12, 13). In general, two roll take-up devices (7, 8) in each case are arranged next to one another as a double unit on the side arm (5), and of these the first two roll take-up devices (7, 8), as a roll-changing unit, do not have any changing heads in the direction of pivoting towards the roll stand (1). By virtue of this measure, the changing of the rolls can advantageously be performed fully automatically in only about three minutes. <IMAGE>

Title: Damping device for a cylinder assembly which as part of a suspension system is arranged between the sprung and unsprung masses of a vehicle
Inventor: GOENNHEIMER PETER DIPL ING
IPC: F16F9/46
Filed: 1985-08-10
Abstract: A damping device for a cylinder assembly is described, which as part of a suspension system is arranged between the sprung and unsprung masses of a vehicle. For each direction of movement (compression and tension phase) of the working piston of the cylinder assembly, the damping device has a damping valve, which is formed by ducts passing through the working piston in its direction of movement and at least one spring disc covering these on the outlet side, a backing element being assigned to at least the spring disc of the one damping valve, which element can be pressed with adjustable force onto the spring disc by means of hydraulic fluid fed from outside by a pressure generator. In order to ensure that the closing force exerted on the spring disc by the backing element is intensified as the pressure in the cylinder assembly increases, so that the damping force is essentially maintained or increased by a defined amount, a pressure booster with a stepped piston is provided as pressure generator, the low-pressure side of which is connected to one of the two chambers of the cylinder assembly, and to the high-pressure side of which the hydraulic fluid acting on the backing element is applied. The damping device thereby functions independently of any external pressure source.

Title: Device for installing arch stilts
Inventor: GOETTLING WOLFGANG
IPC: E21D11/40
Filed: 1986-05-23
Abstract: In order to install arch stilts in a mechanized fashion in underground mining and tunnelling operations, an installation device is used which has a mounting table which is assigned to a chassis to which are assigned two clamps which are arranged at a distance from one another and are of displaceable design and which mounting table can be pivoted in its entirety about its transverse axis which is located off-centre into the region of the front transverse edge. In this arrangement, the individual movements are brought about by means of working cylinders which are supplied with energy via a supply unit which is assigned to the chassis. Both the pivoting about the transverse axis and displacement including the transverse axis and further adjustment aids are achieved by means of further, correspondingly arranged working cylinders. Thus, it is possible initially to lay the arch stilt legs onto the mounting table for premounting, to connect them to one another and then to move them into the installation position, exact adjustment being possible by means of the different working cylinders. Subsequently, the arch stilt legs are moved apart so that the arch stilt can be installed with exactly predeterminable pretensioning. <IMAGE>
