Title: Centrally controlled telephone PBX - has circuit for transfer of call from one extension to entitled extension in same group
Inventor: PATTYN JEAN-LUC
IPC: H04M3/54
Filed: 1974-08-14
Abstract: Code signal switching means are provided for each transfer type (internal or external transfer) and/or connection line type for initiation of identification of a transfer (HU en 1, AUen1) engaged for a not yet accepted call to an extension which is not answering. These switching means (GH, GA, GR) control the diversion of the call to an extension which answers. A number of house transfer lines are available for interchange, and are intercepted by means of call pick up lines. Links are made through transistor amplifiers appropriate to each line. The lines are arranged in groups - single line, ten line and mixer line couplings corresponding with the entry points.
Patent DE-2441267-A1 (DE)
Title: Voltage instantaneous frequency digital measuring cct - has first comparator for D.C. voltage corresponding to instantaneous frequency
Inventor: SCHIRMER KLAUS DIPL ING
IPC: G01R23/09
Filed: 1974-08-28
Abstract: The d.c. voltage corresponding to instantaneous frequency is compared with an adjustable auxiliary voltage, and its pulse at equality of both voltages determines the measurement instant. The d.c. voltage is derived from the instantaneous frequency through a frequency-voltage convertor, which comprises a capacitor periodically charged with a constant charge at the instantaneous frequency, and continuously discharged through a resistor. The above d.c. voltage appears at its terminals as the mean voltage. A second comparator compares the adjustable reference voltage with a stepped voltage derived from a fixed frequency generator through a circuit corresponding to the frequency voltage comparator, but without the resistor.

Title: Complex ceramic heating element - has wires pressed into continuously moulded ceramic and sintered to increase heat transfer
Inventor: GARBE GUENTER
IPC: H05B3/52
Filed: 1974-10-28
Abstract: The complex ceramic heating element has two or more metal heating conductors per element sintered into the ceramic either in wound form or straight. The ceramic shrinks by a given amount and has a lower coefficient of expansion than the rigidly enclosed metal heating conductors. The element has no metallic sheathing. During production the zig-zag or helical resistance wire is continuously embedded in the ceramic and the latter is then pressed into the required shape, cut, dried and finally sintered. The advantage lies in better heat transfer and radiation properties, and greater thermal shock resistance.

Title: Hydraulic damper for tipod mounted television camera - provides damping with fine clearances between discs
Inventor: THOMA GEORG
IPC: F16M11/06
Filed: 1974-12-04
Abstract: The shaft (1) which supports a T.V. camera has a number of discs (8) clamped between spacer rings (9) and bearings (4, 5) by the nut (10). Damping is provided with a viscous medium in the two part casing (2, 3) which fills the fine spaces between the inner discs (8) and alternate discs (11). The latter discs (11) are attached to the casing by teeth (16) which engage the ends of the cross pins (14) in the main pins (13). Rotating the end cover (20) moves the main pins (13) axially and varies the number of discs (11) which are locked to the casings and so varies the damping force. This design is cheaper than one using concentric cylinders.
