Patent DE-3703577-A1 (DE)
Title: Trigger device (discharging device, firing device) for air-pressure weapons
Inventor: KUENSTLER GERD-DIETER
IPC: F41B11/723
Filed: 1987-02-06
Abstract: The air which is compressed and stored in a compression chamber in the air-pressure weapon acts in the sense of increasing the retaining force on the valve head of a valve which connects the compression chamber to the barrel of the air-pressure weapon. When the trigger is operated, a spring-loaded firing element strikes the valve stem and opens the valve. In order to reduce the firing energy required, the valve stem is loaded by spring elements against the valve retaining force during or after the compression process. The loading is effected by the closing movement of the breech element, which acts on the spring elements via a control cam and prestresses them. The prestressing of the spring elements and of the valve stem against the valve retaining force reduces the necessary impact energy of the firing element and thus also the vibration of the weapon during firing. This results in a significant improvement in the firing accuracy.

Patent DE-3724894-A1 (DE)
Inventor: BORNHOF HANS-ULRICH ING GRAD
IPC: F16K31/365
Filed: 1987-07-28
Abstract: In a valve device for fluids under pressure, having a diaphragm which is subject to the pressure of the fluid under pressure, it is normal to influence at least one operating parameter by the magnitude of the effective area of the diaphragm which is subjected to the pressure. In this case, the magnitude of the effective area is defined by the dimensions of a support on the housing side. To change the magnitude of the effective area, it is known for the housing part carrying the support on the housing side to be replaced. A wide range of adjustment possibilities for the magnitude of the effective area necessitate a correspondingly wide range of housing parts, with a correspondingly high cost. This cost is reduced by means of the invention. The invention proposes to provide at least one housing insert (1) to support the effective area (12, 15) of the diaphragm (2). <IMAGE>

Title: Blister-free bitumen roof
Inventor: GRUEN INGO DR ING
IPC: E04D11/02
Filed: 1987-10-03
Abstract: According to the invention, adhesive sheets or weldable sheets of polymer-modified bitumen adjusted to have a high softening point are adhesively bonded by the pouring and rolling down process, which may take place with a high degree of heat. As a result, any moisture present evaporates and genuinely full-area adhesive bonding without defects is obtained, which guarantees a blister-free bitumen roof with high reliability, even in inclement weather. The novel feature of the invention is that the elasticity of polymer-modified bitumen is utilised for a high softening point and thus for a high heat of adhesion, and not only for the elasticity of the roof membrane. It is advantageous if, in addition, an insulation which is insensitive to heat, for example shaped glass, is used and if the adhesion bonding is carried out in a full-area manner, not spotwise or stripwise, onto said insulation.

Filed: 1987-10-06
Abstract: There are known housings for bimetallic measuring mechanisms which take the form of a one-piece measuring mechanism carrier with screw and press-in bearings for the measuring mechanism spindle on which, as a rule, two bimetallic spirals are arranged. In this case, the assembly of the measuring mechanism is relatively difficult and time-consuming, particularly because of the processes of screwing or pressing-in the measuring mechanism spindle to a specific amount. By means of the novel housing, particularly by the design and arrangement of the bearing for the measuring mechanism spindle, installation of bimetallic measuring mechanisms of the most compact design in a simple, quick and reliable manner is to be made possible.   The housing is divided into two in the region of a plane running in the direction of the measurement mechanism spindle and consists of two measuring mechanism carrier parts (1, 2), which are connected to each other in the installed state of the measuring mechanism with the aid of snap connection means (3a, 7a; 4a, 8a; 3b, 7b; 4b, 8b). Before putting together the housing, the measurement mechanism spindle (47) with the spiral spring set may be inserted in a simple manner in the bearing (18, 19) of one of the two measurement mechanism carrier parts, which are then joined together with the aid of snap connection means.

Title: Inking unit for printing machines
Inventor: ARNOLD WOLFGANG DR
IPC: B41F31/04
Filed: 1988-05-30
Abstract: The invention relates to an inking unit for printing machines, in particular for double printing units on web-fed rotary printing machines with ink supply from the top. The object according to the invention, which consists in providing a short inking unit for the ink supply from the top, is achieved in that the screen roller disposed ahead of the printing forme cylinder and the ink applicator rollers of the upper inking unit are functionally assigned a metering system which is formed from the combination of a wedge-shaped ink fountain, which is known per se, consists of an ink feed roller and an ink knife and constitutes the preliminary metering system, and from an ink accumulation space consisting of the ink feed roller, the screen roller and a doctor blade which is operatively connected to the screen roller. With the metering system according to the invention, it has been possible to develop a short inking unit for the ink supply from the top which is similar to the short inking unit which was previously suitable solely for the ink supply from the bottom on double printing units. Even in this case, a clean ink supply and an even and accurate ink metering are now ensured with an extremely low number of inking rollers. <IMAGE>

Title: Hydrodynamic torque converter with integrated clutch
Inventor: SCHROETER HEINRICH
IPC: F03B3/10
Filed: 1988-08-20
Abstract: Hydrodynamic torque converter with integrated clutch, characterised in that the converter consists of a cross-flow pump module and a cross-flow turbine module in accordance with DE 3628946 A1 and has had added to it a bypass flap 2 and control flaps 1 + 3. Control flap 3, which is firmly connected to control flap 1, here assumes the function of the clutch since it interrupts the power flow from the input to the output when closed. Like the control flap 1, it consists of the curved surface of a cylinder and two circular discs, which can be pivoted coaxially as a unit about the respective rotor. Control flap 1 reduces idling losses by limiting and safeguarding residual circulation via bypass flap 2 for the purpose of heat dissipation. For circulation of the operating media, the converter connection studs are to be connected. The cooler, the aerator and the expansion tank are arranged externally in the connecting line. <IMAGE>
