Title: Link support weighing cell - ensures low tilt and eccentricity errors by appropriate radius to height selection
Inventor: FRITZ HARALD ING GRAD
IPC: G01G3/12
Filed: 1980-11-07
Abstract: The weighing cell, with spherical segment rolling surfaces and plane parallel bearings, eliminates tilt errors as far as possible as well as small eccentricity errors. Tilt error is reduced by selection of the relationship between the radius of curvature and the structure height. The cell can be used in supports for fixed weighing platforms. The ratio between the spherical radius (r) of the rolling surface and the height (a) of the weighing cell is chosen to lie between 1/4 and 1/2. The cell is applicable in large platform weighing equipment and for container weighing. It entails a smaller degree of eccentricity of horizontal displacement between a platform and base than with more lens-shaped cells of conventional design.

Patent DE-3107869-A1 (DE)
Title: Positioning arrangement for grinding body and gear on tooth-flank grinding machines
Inventor: LENZ SIEGHART DIPL ING
IPC: B23F5/08
Filed: 1981-03-02
Abstract: A positioning arrangement for grinding body and gear on tooth-flank grinding machines which work by generation grinding with indexing control and in which the infeed adjustment at the workpiece is produced indirectly by means of backlash changes in the rolling gear train. A reduction in the auxiliary time components is achieved, and furthermore operating errors are eliminated. At a defined backlash span in the rolling gear train, positioning of grinding body and gear is produced by a repeatable sequence of operating steps and by means of signalling the contact between grinding body and gear. Within a section of the set rolling path in which contact between grinding body and gear is possible, the operation is run at slow rolling speed and continuous infeed movement until contact between grinding body and gear, and the associated position of the infeed drive is stored. Furthermore, axial play, which must not fall below the limit value, is produced at the threaded-spindle bearing arrangement. The positioning of the grinding body relative to a tooth flank is also carried out for the second tooth flank of the tooth gap and then both infeed drives are reset by half the amount of the sum of the infeed values achieved - relative to the initial position - for right-hand and left-hand flanks. Field of application is the grinding of gear tooth systems. <IMAGE>

Patent DE-3112295-A1 (DE)
Title: Fuse base for melting-fuse inserts
Inventor: JAHNKE GUENTER
IPC: H01H9/10
Filed: 1981-03-27
Abstract: The fuse base (1) for melting-fuse (fusible link) inserts (5) is additionally provided with a fuse load switch whose switching rocker (16) preferably blocks access to the fuse insert (5) in the switched-on position and which, in the switched-off position, holds the contact link (15) of the fuse load switch, via a displaceable push rod (25) in the contact-opening position against closing-spring pressure (22, 23). A blocking device makes it possible for the contact link (15) to return from the switched-off position to the switched-on position only when the mating contact of the melting-fuse insert (5) is in a position corresponding to a minimum contact pressure. For this purpose, when the switching rocker (16) is in the switched-off position and when the mating contact (14) of the fuse insert (5) is in a control position which does not ensure the contact minimum pressure, the slide (52) blocks the return displacement capability of only the push rod (25). <IMAGE>

Patent DE-3116176-A1 (DE)
Title: Wedge-shaped strap
Inventor: DUBISZ ENGELBERT
IPC: E21D11/22
Filed: 1981-04-23
Abstract: In underground mining and tunnelling, web section segments which are connected to one another in a butt-jointed manner via straps are used in arched and annular roadway support. In this arrangement, the straps are let into the web sections in such a way that there are no projecting parts. These straps are castings or forgings having a solid, continuous rib in the joint area of the section segments. The castings or forgings have bearing surfaces which can be pressed against the inner surface of the section segments, while they leave an intermediate space towards the web so that they are pressed in a wedge shape into the section when the screws arranged in a sunk position are tightened. Here, the bearing surfaces themselves are to have several sectional areas which follow one another in the longitudinal direction of the straps, are angled differently and in each case correspond diagonally on the top and bottom longitudinal side, which leads to reliable bearing of the corresponding surface against the sections.

Title: Propelling pencil with an electromechanical refill feed
Inventor: BOPP ACHIM PROF DIPL ING
IPC: B43K21/027
Filed: 1981-10-23
Abstract: The propelling pencil has an automatically operating electromechanical refill feed. The refill (20) is fed by means of a feed unit (13) which grips the refill (20) via a ball locking mechanism (13b, 13g). The feed unit (13) projects with an armature (13b) into a drive movement magnet (14). When the magnet coil (14a) is energised, the armature (13b) is drawn against the magnet core (14b) of the drive movement magnet. In contrast, the refill (20) remains in its original position, since the ball locking mechanism with the balls (13d) opens. When the magnet coil (14a) is deenergised, the armature (13b) moves, and with it, via the ball locking mechanism (13d) which is now closed, the refill (20), under the influence of the untensioned helical spring (13e) in the direction towards the tip of the writing device. This results in an electromechanical movement of the refill feed. The movement magnet (14) is supplied by a battery (18) which is housed at the end of the writing device. Control electronics (19) ensure that the magnet coil is energised in each case only by a pre-controlled quantity of current. <IMAGE>

Title: Digital converter device and method for converting an analog signal into a digital signal
Inventor: SPEED ROBERT F
IPC: H03M1/00
Filed: 1981-11-26
Abstract: A direct conversion of an analog signal having a low signal level into a corresponding binary digital signal is achieved by a device which comprises a clock generator for generating a current of pulses and a pair of gates which optionally conduct the pulses via one of two current paths in dependence on a predetermined difference between the analog signal and a control signal. A counter chain provides an up/down counting of the pulses conducted via associated current paths and generates a binary digital output signal corresponding to the analog signal. A pair of digital/analog converters converts the digital output signal into a continuous step-shaped signal which is compared with the analog signal in a voltage comparator and amplifier. A differential signal is generated for a difference between analog and control signals and applied to the gates in order to determine the selection of the current paths and to enable the counter chain to track the analog signal.
