Title: Control circuit for busy lamp in telephony - uses call-cost metering pulses to cause illumination of busy lamp at operators console
Inventor: SCHMID ADOLF ING GRAD
IPC: H04M3/51
Filed: 1978-09-22
Abstract: The control circuit uses call-cost metering pulses to initiate the lighting of the busy lamp at the special operator's console when an incoming call finds the console busy. The metering pulses still continue to be supplied to the call meters or counters for normal subscriber call metering. The interval (for example 5 seconds) of the metering pulses is fixed. The devices that control the busy lamp have a relaxation delay lasting slightly longer than the time between two metering pulses. The timer typically consists of a series RC circuit in parallel with a switch (S).

Title: Async. linear motor with laminated core inductor - has each core lamination of frame cross-section of different height and width, larger laminations surrounding smaller ones
Inventor: BOCHAROV VASILY IVANOVITSCH
IPC: H02K41/025
Filed: 1978-11-02
Abstract: The motor is intended for high speed floor conveyor systems, but is suitable for various electric drives with linear, or reciprocal movement of operating members. The inductor core (2) laminations are slotted for retention of a polyphase coil. The motor contains a secondary element, in relation to which the inductor moves, having a conductive part mounted on a magnetically conductive base plate. Each core lamination is frame-shaped in cross-section, the frames having different height and width in relation to the inductor movement. Thus each lamination of greater dimensions surrounds a smaller lamination. The design avoids ineffective air gaps between the core laminations, which could inhibit the faultless operation. The preferred lamination material is steel. Polyphase coils may be of composite or divided design.

Patent DE-2942530-A1 (DE)
Inventor: RITZ GEROLD
IPC: H02G1/12
Filed: 1979-10-20
Abstract: The device has a spindle (10), which is caused to rotate by a motor, and supporting rods (24), which are supported obliquely thereto such that they can rotate, and support, at one end, cutting tools (22) for stripping the insulation and, at the other end, flyweights (28). During rotation, the flyweights (28) are drawn outwards by the centrifugal force, thus twisting the supporting rods (24), pressing the cutting tools against the insulation and starting to remove said insulation. The limiting value of the pivoting range of the cutting tools is adjustable and, in consequence, can be matched to the respective diameter of the conductor from which the insulation is to be stripped. An indicating device on an actuating ring allows the cutting tools (22) subsequently to be reset to the diameter of a conductor which has already previously been stripped of insulation. In consequence, a single device can be used for stripping the insulation from electrical leads having a relatively large cross-section, with only a short resetting time. <IMAGE>

Title: Electric module encapsulation - by dipping in acrylic! resin and UV irradiating to harden
Inventor: GARZ DIETER PAUL WILLI DR RER
IPC: H01B3/44
Filed: 1979-11-07
Abstract: Electrical modules such as resistors or capacitors are embedded in an insulating enclosure by dipping into a resin on an acrylic basis which can be hardened by ultraviolet irradiation. A few seconds of exposure are adequate to cure such resin without any heat application. The electrical properties of the modules are thus not thermally affected. The time required for the treatment is much reduced and the greatly reduced shrinkage lessens the compressive stress on the module. A transparent or translucent resin is preferred because it ensures a thorough curing. The encapsulated module is thus firmly enclosed in a flame inhibiting material.
