Title: Red mud filler for bituminous road coatings - where alkali materials in red mud are neutralised so filler contains aluminium hydroxide gel
Inventor: BAYER GERHARD
IPC: C04B18/04
Filed: 1980-09-20
Abstract: The filler contains an aluminium hydroxide gel, which is formed by at least partial neutralisation of the alkalies in the red mud. The alkalies pref. consist of soluble sodium aluminate and insol. sodium alumium silicate. The red mud pref. also contains SiO2 gel, and a frost-inhibitor, esp. NaCl. The filler pref. has a grain size below 1 mm; and the grains are pref. coated with higher hydrocarbons, esp. diesel oil. The red mud is pref. neutralised by being stirred with an agent, possibly after the addn. of NaCl. The agent is pref. AlCl3 and/or Al2(SO4)3, and/or HCl or H2SO4. The mixed is then pref. dried and milled. Useful as a filler added to bitumen to make road coatings, where the filler may also inhibit frost, esp. when it contains HCl. The filler is simple and inexpensive to make, and does not create dust.

Title: Sensor controlled chipping device for wooden waste blocks - has container with chipping tools with inclined bottom plate, and tools movable parallel to bottom plate plane
Inventor: ROESSLER PETER
IPC: B27L11/02
Filed: 1980-10-27
Abstract: The chipping device has several chipping tools driven in a vertical container. A bottom plate (22) of the container is inclined to the vertical, and the tools (34) can be mounted in a direction parallel to the bottom plate, aligned in rows in the movement direction. The container wall (20) adjacent to the lower end of theinclined bottom plate has apertures (32) for the tools. A sensor (50) responds to the chipping tools operation at excessive and/or too low movement resistance, and the operational direction of the drive can be reversed for a short time period by the sensor output signal. This may take place via a low speed clock pulse generator circuit. The drive reversing signal may be masked by a circuit, under control of another sensor, responsive to a reverse run of the chipping tools. The short time period may be determined by a monostable timing element.

Title: Device for simultaneously measuring  alpha - and  beta -rays by means of a proportional counting tube
Inventor: LEHMANN KLAUS DR ING
IPC: G01T1/18
Filed: 1981-07-25
Abstract: The pulse rate supplied by a counting tube (3) is linearly amplified in the preamplifier (5). In a following low-pass filter (6), the noise is reduced and the pulse length is limited in conjunction with the parts (4 and 5). Then the dynamic pulse range is reduced in a logarithmic amplifier (7). The widening of the noise spectrum occurring during this process is reduced in a further low-pass filter (8). The pulse signal is then supplied to two threshold discriminators (9, 10) with a narrow dynamic range which are followed by an evaluating stage (13) of known type which supplies separate alpha  and  beta counts. <IMAGE>

Patent DE-3131310-A1 (DE)
Inventor: PLOEGER HEINZ
IPC: F23M5/08
Filed: 1981-08-07
Abstract: The inner wall of a combustion chamber is composed of a plurality of ceramic plates which are suspended from the outer wall of the chamber by being hooked over mounting portions of the outer wall; this eliminates the need for screws, bolts, welds or the like and facilitates mounting and dismounting of the plates. The plates define with the outer wall a clearance into which cold air is admitted; the upper and lower edges of adjacent plates define with one another respective air gaps communicating with this clearance so that air streams enter the combustion space through these gaps. These air streams prevent the deposition of ash and other contaminants on the inner surfaces of the plates.

Patent DE-3214108-A1 (DE)
Title: Angular drilling jig
Inventor: DAWIDOWSKI GERHARD
IPC: A61B17/17
Filed: 1982-04-16
Abstract: The invention provides an angular drilling jig for drilling holes converging at an angle, in particular for carrying out surgery on bones, consisting of a handle with a cross pin at the proximal end and guide bushes, directed at an angle to one another, on the free ends of the cross pin, which angular drilling jig enables a thread to be passed through the holes formed by means of the angular drilling jig. This is achieved by virtue of the fact that a wire-guide sleeve can be pushed into each guide bush, of which wire-guide sleeves one has an axial bore which at the proximal end leads out in an opening directed perpendicularly to the longitudinal axis of the sleeve and runs curved in the orifice area, and the other has an axial, continuous bore.

Patent DE-3237855-A1 (DE)
Title: Method of automatically machining workpieces
IPC: B24B47/02
Filed: 1982-10-13
Abstract: To automatically machine elongated workpieces (14), a slide (12) carrying a work fixture is moved in a reciprocating manner on a machine table (11). To set the tool, a tool slide (17) with a tool carrier (16) is displaceably arranged perpendicularly to the direction of movement of the slide (12). The time for a machining cycle in the case of firmly predetermined reversal points is essentially established by the velocity of motion of the slide (12) between the reversal points. To reduce the machining time for a workpiece (14), the outer contour of the workpiece is converted by means of an electric device (2) into control commands, in particular into reversal commands, for the slide (12) and into setting commands for the tool slide (17). For this purpose, the electric device (2) measures the current in the drive motor for a tool (15), which current is in a load-dependent relationship with the outer contour of the workpiece (14). <IMAGE>
