Title: Parallel alignment of rock drill slide - uses laser beam through orifice plate pair for shot blasting holes in tunnels
Inventor: BLASE GOETZ
IPC: E21B47/00
Filed: 1977-05-02
Abstract: When parallel shotholes have to be drilled during driving of tunnels and headings in mines, a lack of parallelism caused by the conventional mechanical and hydraulic booms results in high explosive consumption. This can be avoided and the drill rig itself need not be previously aligned if a guide rod (3) is inserted into a pilot borehole (1) in the tunnel face (2), and a laser (4) is fixed to its end. Telescopic arms (6, 7) on the rock drill slide (5), joined by a cross-piece (8), carry orifice plates (9, 10) at the end. When they are adjusted so that the laser passes through both orifices, the slide (5) is aligned parallel to the pilot hole.

Title: Telephone exchange switching circuit - has two relays connecting wires to potential terminals reversing potentials and shorting wires for test purposes
Inventor: OBERHAUSER WALTER DIPL ING
IPC: H04M7/00
Filed: 1977-06-03
Abstract: The telephone exchange circuit has switches each having two wires carrying different d.c. potentials which can be reversed. Potentials are applied through dialling signal receivers, and the switches recognise the closing or breaking of a loop produced between the wires. This information is used, among other things, for test purposes. Polarity reversal of the two line wires is done by two contacts of two different relays, of which two contacts of one relay connect the wires to two terminals with a certain polarity, and the two contacts of the other relay connect them to terminals with opposite polarity. In order to simulate the loop for test purposes, the two wires are short-circuited by closing the two paris of contacts simultaneously.

Title: Calibrating parts deep drawn in hydraulic fluid - where retraction of drawing mandrel provides parts with accurate finished size (CS 31.8.78)
Inventor: TOMASEK JIRI DIPL ING
IPC: B21D26/02
Filed: 1978-07-27
Abstract: The part is drawn in an elastic medium, esp. by hydromechanical drawing; and the cross-section (X) of the drawn part is larger near its base than in the remainder of the part. The influence of the elastic medium (e.g. a hydraulic fluid) is then terminated and the drawing mandrel is retracted. The drawing mandrel has an increased dia. on its bottom end which increases dimension (X) when the mandrel is extracted from the drawn part. The pref. mandrel has a major dia. with a taper leading to a minor dia.; and the major dia. pref. forms a flange on the bottom end of the mandrel. Deep drawn parts made via an elastic medium must normally be subjected to a subsequent sizing or calibrating operation. The invention eliminates such operations, thus reducing mfg. costs.
