Title: Subscriber circuit for two exchange lines with one phone - uses bistable relays operated by capacitor discharge when key is pressed
Inventor: HEROLD MANFRED
IPC: H04M9/00
Filed: 1979-07-09
Abstract: A telephone can be connected to either of two exchange lines by lifting the receiver and pressing one of two keys. A capacitor, which was charged through a high resistance choke from the line, discharges through a bistable relay, which switches the line to the phone. If the second key is now pressed, the second line is connected by a second bistable and C, while a relay holds the first line and recharges its capacitor to reset its bistable. Either line can now be used while the other is held. Nothing happens if both keys are pressed together. A held line can be released by a release key. Replacing the receiver releases both hold relays and resets both bistables. Four LEDs indicate which line is in use or held.

Title: Rotary transfer switch selector circuit - uses two-digit dialling numbers for off-main path lateral link preselection
Inventor: SCHLENKER WERNER
IPC: H04Q3/16
Filed: 1979-08-31
Abstract: The circuit represents a modification of the arrangement described in DE1020685 which specifies a transfer switch selector (UWd) for single and double digit preselector numbers whereby in addition to the main communication lines, also subsidiary cross links may be used with the same dial number. For example, a direct lateral connection can be made between two sub-exchanges to which the callings and the called subscribers belong, thus bypassing the main exchanges. The first digit dial number in addition to being sent through the main path, also operates the selector arm (KW1) of the transfer switch circuit and positions it on a contactor, if this corresponds to a position where a bypass is available a relay X draws and holds via 9X. The second digit moves arm (KW2) to a further position. A lateral cross connection is established if the X, U and a C contactors are operated. The a C contactor marks out a cable group (Bd1) to (Bd6) where at least one line is still disposable.

Title: Boring bar reversible cutter - has plate clamp located in lengthwise and transverse directions
Inventor: FUCHS KARL
IPC: B23B27/16
Filed: 1979-09-12
Abstract: The clamping device secures a reversible cutter plate to a boring bar, the latter having a seat for the plate and two support faces inclined to each other. A clamp is pressed vertically down onto the plate and has a chamfer bearing against one on the latter, so as to thrust the plate towards the support faces along the line bisecting the angle between them. The clamp (18) is located on the boring bar (1) so that it cannot move in the lengthwise direction while bearing on the plate (11) at right angles to the latter, and in addition is located in the transverse direction also. It is so positioned that the clamping force is directed along the bisecting line between the support faces (3,4) even when its own lengthwise direction deviates from this line.

Patent DE-2945774-A1 (DE)
Title: Electronic stitch-pattern controller for zigzag sewing machine - is disengageable for plain-stitch production by mechanical means
Inventor: HANYU SUSUMU
IPC: D05B73/00
Filed: 1979-11-13
Abstract: An automatic zig-zag sewing machine has electronic control circuits for the prodn. of fancy stitches which can be disengaged in favour of a mechanical system for the execution of simpler linear stitches. The switch over is effected by a selector dial on the front of the machine which turns a series of coaxial cams to switch off the power to the electronic circuits, engage a mechanical material-feed control, fix the needle-bar in a single position and change the stitch-plate aperture from zig-zag to straight stitch pattern. Since linear stitching constitutes more than 90% of the normal use of a sewing machine, this arrangement saves power by not activating the control circuits unnecessarily, and avoids overheating the circuit components. It enables the machine to be used for linear stitching even if the electronic controls are malfunctioning. The noise output in mechanical mode is lower than in automatic mode.

Title: Surgical HF cutting instrument - preheats cutting electrode resulting in reduced HF power requirement
Inventor: ROOS EBERHARD
IPC: A61B18/08
Filed: 1980-10-22
Abstract: This surgical h.f. cutting instrument requires only a fraction of the usual h.f. heating power, thus avoiding the risk of arc formation and also extending the life of the cutting electrode. This is achieved by pre-heating the electrode by means of a d.c. or l.f. current. The cutting electrode (11) has a cutting edge formed by a wire loop (16) with high resistance which is pre-heated to about 100 deg. C. by the current from the l.f. generator (13). A h.f. generator (12) provides the energy for the fan-shaped h.f. field which converges on the loop, thus raising its temp. to 300-600 deg.C.
