Title: Building-material preparing and conveying installation
Inventor: RIKER RUDOLF ING GRAD
IPC: B28C9/00
Filed: 1986-02-12
Abstract: The invention is concerned with a building-material preparing and conveying installation which uses as a basis an inclined single-shaft compulsory-type mixer which at the same time serves as a weighing and metering container and is moved in the longitudinal direction from its filling position into its emptying position. By setting a certain length of the travelling path, a variable discharge height can be achieved. The building material, for instance concrete or mortar, can in this way be transported directly to a desired height at the building structure. The metering of the components into the mixing container, resting on a balance, may be performed manually or by machine directly from ground stores, from metering installations in series or mobile silos.   In the combination of metering and mixing device with a star metering installation, the metering tower with the scraping mechanism is attached onto the travelling frame, so that a road-going or containerisable unit is produced. The variability of the adaptation of the basis installation comprising the weighing, mixing and transporting unit to the various application requirements and needs is illustrated in many examples. <IMAGE>

Title: Hand plane
Inventor: SEIFERT JUERGEN
IPC: B27G17/02
Filed: 1986-02-24
Abstract: There is described a hand plane with a plane-iron arrangement which is capable of fine adjustment, is accommodated displaceably and with lateral play in a plane hole of the plane, is coupled to an adjusting device for setting the cutting depth and the cutter alignment, and can be fixed by means of a fixing device in a predetermined set adjustment position, the plane-iron arrangement being pressed flat against a bearing surface in the plane hole for this purpose. The adjusting device for setting the cutting depth has a differential thread adjusting spindle, the first thread portion of which is in engagement with a part of the plane which is fixed against displacement and the second thread portion of which is in engagement with a driver for the plane-iron arrangement which is displaceable relative to the plane body. Provided in the region of the plane hole is a clamping claw which clamps the plane-iron arrangement against the bearing surface and is preferably formed by a double-armed lever which can be pressed against the plane-iron arrangement by its two ends, while being supported in an intermediate region on a tie rod passing through it. This design of the adjusting and fixing device makes it possible to clamp the plane-iron arrangement firmly against the bearing surfaces with the lowest possible weakening of the plane body and with a construction appropriate for the material involved and to make extremely fine adjustments to the plane cutter without thereby unduly increasing the manufacturing expenditure...

Title: Operating device for process control
Inventor: GRUBE WOLFGANG DIPL ING
IPC: G06F3/043
Filed: 1986-07-09
Abstract: The measuring tablet of an optical digitising device is constructed so that the marked image positions are specified in two screen co-ordinate systems (X1, Y1; X2, Y2). Both co-ordinate systems lie in one plane, and are rotated through 180 DEG  relative to each other, i.e. each image position is measured from two opposite sides of the measuring tablet. By forming the sum of the measured co-ordinate values (X1<*>, X2<*>; Y1<*>, Y2<*>) and testing the sum to be within specified limiting values, measuring errors can be identified. The invention is explained using as an example an operating device which works on the magnetostrictive principle, and in which the individual co-ordinate measured values are determined using time division multiplexing. <IMAGE>

Title: Magazine for driving in pins and nails or the like - of different lengths
Inventor: BADE HEINZ EMIL
IPC: B25C1/00
Filed: 1986-08-26
Abstract: The improved magazine can receive and handle all known types of pins and nails, in comparison with known tools which are to be loaded either from the top, the rear or else laterally and can generally handle only one sort of driving-in means of a predetermined shank length. The object of the invention was to improve a magazine of the generic type in such a way that a continuous guide plate with grooves for different shank lengths is congruently assigned a further plate, which does not cover the entire shank length and is likewise grooved, and is unchangeably connected to it. In known magazines, a special type of strip, or else other auxiliary means dependent on the chosen shank length, must be displaced either above or below the pin/nail strips. According to the innovation, only one bar is to be pushed from behind into the grooves open between the plates and fastened in a bore. Such a simple auxiliary means secures in particular headless pin strips against tilting and shifting during overhead work with the tool and affords, by means of the second plate, a considerably improved guidance for all known driving-in means of the above-described type.
