Abstract: The invention is a drafting frame of a spinning or twisting machine comprising a plurality of roll pairs or roll triads comprising upper and lower rolls, the upper rolls being guided at their ends by bearings in at least one supporting arm rotatable about a pivot shaft with the spacing of the upper rolls from each other being changeable. Each of the bearings is a guide means, advantageously an open ended slot, aligned with an axis of a lower roll. Every supporting arm has at least two guide means spaced from each other for at least one of the upper rolls.

Abstract: A power brush e.g. for a vacuum cleaner or street sweeper has its bristle bodies swivelably mounted on a member which is given an orbital movement so that the eccentric axes of the bristle bodies with respect to their swivel axis induces an additional oscillatory motion of each bristle body as it moves in the orbital path generated by the motion of the member on which its carrier is mounted.

Abstract: A circular groove present on a journal on its end is utilized to provide a bayonet coupling on the journal without mechanical refinishing work to fix or clamp a ring piece axially on the journal. The clamped supporting elements of the bayonet coupling are formed as a divided supporting ring whose collar engages in the circular groove and is rigidly nonrotatably held in it. The circumferentially divided supporting surfaces of the supporting ring are assembled by attaching members correspond in the locked configuration with the interiorly directed circumferentially divided abutting surfaces of the clamped ring piece which form the rotatable portion of the bayonet coupling.

Abstract: A multi-axial industrial robot having a compact modular design for the drive system, which can be varied in numerous ways. The robot consists of a column or stand (1), with a rocker arm (7) swingably supported thereon and an outrigger (9) swingably supported on the rocker arm. The modular construction system is achieved by locating in the rocker arm (7) the oscillatory drive (26) for the outrigger (9), as well as the oscillatory drive (16) for the arm itself. Preferably, in the rocker arm are housed the complete drives (16, 26) with only the off-drive members (21, 31) protruding outwardly. Off-drive members (21, 31) are centered and connected non-rotatably with the stand (1) and the outrigger (9). As a result, the rocker arm (7) rotates about the fixed off-drive member (21) with respect to the housing. Drives (16, 26) consist each of a motor (11, 13) and a two-step timing-belt drive (17, 20 and 27, 30), whose second step can be a gear transmission.

Abstract: A keeper according to the invention is used in combination with a motor-vehicle door post and with a latch fork displaceable in an inward direction toward and an outward direction away from the post on closing and opening of the respective door. The keeper has a U-section sheet-metal frame having flanges secured to the door post and formed with a throughgoing passage open transversely of the directions and having relative to the directions an outer edge. An incompressible but elastomeric damper insert received in the frame has a throughgoing passage aligned with that of the frame, engages inward and outward laterally past the frame, and is formed with a groove opening inward at the outer frame-passage edge. A hard metallic abutment of mushroom section has a central outwardly flared stem snugly received in the groove and tabs outwardly overreaching and overlying the outer frame-passage edge and defining an inwardly convex surface.

Abstract: My conveyor comprises an associated track-bound car including a drive motor supplied with drive current by current-carrying rails, a container, and a cover for the conveyor, as well as a track on which the conveyor runs by a plurality of stations. In order to prevent unauthorized opening of the cover a latch of a locking mechanism mounted in the track-bound car is restrained in a locked configuration. The latch can be unlocked by an electromagnetic unlocking mechanism mounted in the track-bound car. A very simple control of the unlocking mechanism can be provided, when, at a position or station in the conveyor where it is to be unlocked, an unlocking signal generator is present, which is automatically connectable with the track-bound car, in order to supply the unlocking mechanism with a required unlocking current.

Abstract: A supply device with a vibrating cylindrical container for the supply of products, via a multiple channel device, to machines for blister packaging, in which the container has a vertical axis which is eccentric with respect to the vertical axis of the vibrator device and has an annular base which develops in an ascending manner over a first portion starting from the multiple channel device, followed by a second portion which develops conventionally. Guide and flow stop means are provided along the base sections with ascending and conventional development as well as supply means for supplying the products into the peripheral zone of the container and suction means to suction the dust and/or fragments of products below the base of the container at the opposite sides of the multiple channel device.

Abstract: An apparatus for controlling the flow of a pressure fluid in a motor includes an arm which cooperates with a locking device to regulate the flow of the pressure fluid through a shut-off member or valve. The arm is connected to a lever which is pivotable about the same axis as the arm. Through resilient means, the arm and the lever are prestressed so that upon movement of the lever into a predetermined position, the arm which is locked in its end positions by a respective lock pawl is released and impelled from one end position into the other. During the movement of the arm, the shut-off valve is actuated so as to regulate the pressure fluid.

Abstract: A method of recovering a metallic aluminum from an aluminum-containing slag of an aluminum smelting process. In this method, the slag is crushed a number of times with each crushing product being separated by a screening off removing the metallic aluminum before the next crushing stage. Water-soluble components are then removed from the slag by leaching and the leaching solution is evaporated to enable recovery of these components.

Abstract: For imitating periodic signals occurring in digital transmission systems during some operating conditions in view of the multiplex structure a word generator is proposed which includes a read-only memory from which during a test signal cycle only 4116 permutations are successively read out of a total of 65,536 possible word sizes and permutations of e.g. a 16-bit word. The remaining 61,420 permutations are generated by shifting bit-by-bit the entire packet of continuous signals so that in case of a fixed 16 bit pattern the packet starts at a different bit position during each successive cycle and after 16 cycles all 16 bit positions occur as begin state. The shift is caused by a framing bit sequence which determines the test signal cycle and whose length is aliquant to n=16.

Abstract: A flat flexible ballpoint pen is formed from two foil strips which are bonded together along their peripheries except for one end through which the writing cartridge is inserted. A case also formed from flexible strips in a similar manner can accommodate the body carrying the cartridge.

Abstract: Solid fuels are gasified in a fixed bed under a pressure from 5 to 100 bars by a treatment with oxygen, water vapor and carbon dioxide. The raw gas from the gasifier is cooled so that an aqueous condensate is formed, at least part of which is burnt in a fluidized bed furnace at temperatures in the range from about 750.degree. to 1000.degree. C. The resulting combustion gas contains water vapor and is supplied to the gasifier. The condensate which becomes available as the raw gas is cooled may be treated in a separator to remove at least part of its dust and tar contents before the condensate is supplied to the fluidized bed furnace. A circulating fluidized bed is preferably maintained in the fluidized bed furnace.
