Title: Bit for hand power drill e.g. for drilling plastics - has single cutting edge with smooth support face diametrally opposite
Inventor: BOMME WALDEMAR
IPC: B23B51/00
Filed: 1976-01-24
Abstract: A drilling bit for use with a hand power drill has only one cutting edge at the tip and one cutting edge along the conical tapered surface. The cutting edge of the tapered surface (shown in cross-section through the bit) is immediately followed by an arc of reduced radius; this again is followed by an arc, generally located opposite to the cutting edge, of 120-180 degrees in which the full radius is used to provide a support surface opposite to the cutting edge. A considerably greater degree of flexibility in use is obtained; in particular, it is not important to keep the bit correctly aligned and if it is out of alignment with the drilling direction it does not jam in the hole and there is no risk of breakage. There is no risk of jamming, leading to injury of the operator. As a result, much larger diameters can be drilled with safety using a conventional hand drill than was previously possible.
Patent DE-2603484-A1 (DE)
Title: Smoothing or satinising rolls for paper - are in horizontal stand with springs between bearings
Inventor: SCHLUNKE JUERGEN
IPC: D21G1/00
Filed: 1976-01-30
Abstract: A paper calender comprising esp. smoothing and glazing or satinising rolls has all the rolls mounted in one or two horizontal planes; a piston-cylinder unit applies mutual contact pressure between all the rolls in one horizontal plane. Springs are located between the bearings of successive rolls so that, if the pressure of the cylinder is released, the roll bearings are forced apart and the gaps between the rolls are increased. Pref. the springs furthest fromt he piston-cylinder unit are stronger than those nearest to it. The strength of intermediate springs decreases accordingly. A uniform contact pressure is obtd. between all the rolls, irrespective of their weight; if it is necessary to separate the rolls, for example if a sheet of paper becomes torn, this is rapidly done by relaxing the force of the piston-cylinder unit, whereupon the springs separate the rolls. Moreover, by contrast with a vertical stand, the self-weight of the rolls has no effect upon their mutual contact pressure.
Patent DE-2611561-A1 (DE)
Inventor: KAISER HILDEGUND ING GRAD
IPC: H04Q1/32
Filed: 1976-03-18
Abstract: In a time division multiplex system for PCM signals, the switching codes must be transmitted, as well as telephony signals. If two-wire connections between exchanges are used, the codes are transmitted via the speech cores in both directions. To reduce power consumption, the circuit arrangements for receiving loop codes are not in relay form but fully electronic. In this case, it is necessary to ensure both low cost and suppression of interference voltages generated in the speech cores. A code evaluation device (SZA) is therefore provided, and supplements the three transmitter-sensor combinations (FHP, FHM, FNP) which are provided for code input and output. <IMAGE>
