Title: Template for spray marking of characters on moving surface - has two blocks provided with several nozzles to produce overlapping paint strips
Inventor: FRAHM UWE
IPC: B41M5/00
Filed: 1980-04-19
Abstract: The appliance is for the marking of movable surfaces, using two spray blocks, each with several spray nozzles. The first block has seven nozzles, located in the centres of two squares, which are positioned above each other. The nozzles (1.5,1.6) located on the left vertical square sides of the first block (1) spray paint strips, which are at an angle to the central nozzle (1.7) on the central horizontal square side. The second block has five nozzles, staggered above each other. The central nozzle sprays a shorter paint strip, coinciding with the strip sprayed by the central nozzle of the first block. The nozzles neighbouring the central one, produce inclined strips, forming a diagonal cross with the strips from nozzles of the first block. The top nozzle produces a short horizontal strip, the lowest nozzle a vertical strip, which do not coincide with similar strips from the first block.

Title: Control circuit for asynchronous rotating machine - monitors supply frequency and machine speed to restart if necessary (NL 16.07.82)
Inventor: SCHOERNER JOCHEN DR ING
IPC: H02P1/30
Filed: 1980-12-19
Abstract: The control circuit changes over (during starting in a frequency range from zero to a given variable limit) from voltage control supported by current control to purely current control, the voltage controller being disconnected. The current amplitude occurring during starting is set between a maximum and zero. The rate at which the frequency changes during starting is also controlled. Whenever the frequency limit is reached a check is made to see whether the machine's speed is following the given frequency or whether the machine has become asynchronous in which case the frequency is reset to zero and the machine restarted.

Title: Multispeed epicyclic gearbox assembly - has independently rotating planetary pinions meshing with sun-wheels of different dia.
Inventor: AHLEN KARL GUSTAV
IPC: F16H3/66
Filed: 1980-12-24
Abstract: The epicyclic gearbox has more than four forward speeds. It is esp. for lorries or earthmoving machines, and comprises two gear trains one after the other coupled by a single intermediate shaft, each having a member lockable by a frction clutch. The planetary pinions each have two or more sets of teeth of different dias. meshing directly with three or more sun wheels or annuli. One of the latter forms the input member of the gear train and the remainder can be friction-braked by servo motors fixed in the housing, while the planet carrier forms the output member. Seen in the direction of power flow, an annulus meshing with the larger-dia. teeth on the planetary pinions of the first train forms the input member, while the sun wheel of the second train forms its input member and meshes with the smaller-dia. teeth of its planetary pinions.

Title: Magnetic roller for electrographic developing and/or duplicating devices
Inventor: MUELLER WERNER
IPC: G03G15/09
Filed: 1981-01-16
Abstract: The invention relates to a magnetic roller for electrographic developing and/or duplicating devices having magnetic strips (1) which are arranged on the circumference of the roller and are mounted on a pole support (2) having mutually bent-away mounting surfaces (3) made from ferromagnetic material. The mounting surfaces (3) of the pole support (2) are parts of an angle profile (6) which is embedded in a moulded part (7) which is made from plastic, extends in one piece between the limbs (6a, 6b) and the longitudinal or bending edges (6c, 6c') of the angle profile (6) and has longitudinal ribs (4) with continuous bearing or aligning surfaces (4a) for the magnetic strips (1). The pole support can be produced as a self-supporting structure with an exceptionally high accuracy of production in a single cycle on a plastics automatic injection moulding machine. A template can be dispensed with in the mounting of the magnetic strips (1). The magnetic strips can be inserted with a very high accuracy into the beds injection moulded in one piece on the pole support, and fastened. They are retained on both sides between the longitudinal ribs of the pole support and lie continuously right up against the mounting surface on the pole support. The magnetic strips are accurately positioned after insertion into the mounting beds on the pole support, and require no further alignment. <IMAGE>

Title: Handtool with a rotatable work spindle for use with a tool insert such as a screwdriver blade, a drill, a cutter, a hexagon box spanner or the like
Inventor: GARNICH ROLF DIPL ING DR
IPC: B25B17/00
Filed: 1981-03-04
Abstract: A description is given of a handtool with a rotatable work spindle for use with a tool insert such as a screwdriver blade, a drill, a cutter, a hexagon box spanner or the like, having a housing mounting the work spindle and an actuating element which can be actuated by hand. The actuating element is displaceable in the direction of the axis of rotation of the work spindle and it acts on the work spindle via conversion gearing. It converts a translatory movement into a rotary movement. Here, the actuating member is designed as a handle (34) with a handle axis symmetric to the axis of the work spindle (24) and running at right angles to the work-spindle axis. The handle (34) is displaceably guided on the housing (10) parallel to the work-spindle axis. It works via the conversion gearing (54; 84, 86) on a drive gear (58; 92) which is rotatably mounted in the housing (10) about an axis perpendicular to the housing centre plane, which plane is preset by the work-spindle axis and the axis of the handle, and works in turn on the work spindle (24) via 90 DEG -deflection gearing (62 to 66; 100 to 106). <IMAGE>

Title: Method and device for controlling the excitation interval of the ignition coil of an internal combustion engine
Inventor: TSUJIMURA MASAKUNI
IPC: F02P7/077
Filed: 1981-03-26
Abstract: The excitation interval of an ignition coil which is determined basically on the basis of the speed of revolution of the machine is corrected in that an extension interval is added which is either a function of the speed of revolution of the machine or is equal to an upper limit value of the speed of revolution of the machine if an acceleration is perceived. The ignition coil is therefore supplied with a primary winding current for a desired interval even in the event of an acceleration so that an adequate ignition voltage is produced in order to ignite the fuel/air mixture in the cylinders of the machine correctly. The extended excitation interval is subsequently reduced incrementally in order to ensure a normal excitation interval in working conditions of the machine other than acceleration.
