Abstract: The mold for the production of concrete shaped bricks has several mold cavities, which are filled with free-flowing concrete. To produce recesses in the interior or on the outer sides of the shaped brick, to each mold cavity there correspond one or more mold cores which penetrate a wiping plate that lies below the mold and project from the bottom into the mold cavities. To demold the shaped brick, the mold cores that are arranged on a core support plate are run out from the mold cavities by a vertical movement relative to the mold and to the wiping plate to the upper limit of the wiping plate, and then the unit that consists of the wiping plate and core support plate is run out in the horizontal direction from the area of the mold.

Abstract: A mold, for the production of concrete shaped bricks having one or more inclined side walls, has an inclined side wall which together with the opposed vertical mold side wall diverges upwardly to form an angle that is opened upwardly, the inclined side wall is moved upwardly in the direction of inclination in order to open the mold and to enable the shaped bricks to be removed from the mold. The movement of the inclined side wall along the inclined space of the shaped brick during removal of the mold results in a smooth clean even surface.

Abstract: A roller vane motor for downhole drilling comprises a housing and a rotor. The housing contains outlet ports and wing deflector cams that divide the space between housing and rotor into chambers. The rotor is provided with recesses in its periphery and there are cylindrical rollers in these recesses which rollers can move between an extended and a retracted position. A portion of the drilling mud that flows through a central conduit in the rotor passes through inlet ports and the recesses into the chamber portions and pushes rollers into their extended position and in a clockwise direction to thus make the rotor turn. Drilling mud of a lower pressure is pushed in from the corresponding chamber portion through the outlet ports into the annular space between the motor and the bore hole wall. When the rollers reach the wing deflector cams, they are forced into the retracted position and their subsequent tasks are then taken over by successive rollers.

Abstract: A barrel retaining device for an automatic pistol has a locking element that locks the pistol barrel and breech both of which are guided on the stock of the weapon. In order to remove the breech with the barrel from the stock in order to disassemble the pistol, the locking element has an actuating element on both sides of the stock which, when depressed, unlocks a lock between the barrel and the stock. At the same time, depressing of the actuation element releases the trigger finger into a forward position to impart a forward movement to a spring loaded trigger arm which is also cammed downwardly to disengage the trigger arm and the driver on the firing pin in the breech. The connections between the breech and the stock are thus released by a single unlocking movement when disassembling a pistol.
