Patent DE-2459053-A1 (DE)
Title: FM directional radio system with RF switching - has amplifier cascade consisting of Gunn and tunnel diode reflection amplifiers and injection sync oscillators
Inventor: SEIBT EDUARD DIPL ING
IPC: H04B7/165
Filed: 1974-12-13
Abstract: The frequency modulated directional radio system with radio frequency switching has a cascade of amplifier stages coupled to the receive antenna. The first amplifier stage is constructed as a reflection amplifier (RV) and consists of a tunnel diode and a Gunn diode amplifier connected in that order. The remaining stages are injection synchronised oscillators (50). The amplifier stages are connected by circulators. The advantage of this system lies in its avoiding intermodulation arising from the frequency becoming dependent on the ratio of output to input power, and in reducing transit time distortion.
Patent DE-2462176-A1 (DE)
Title: Piston type container filling machine - has pistons actuated by slides working between endless tilting tracks
IPC: B65B3/32
Filed: 1974-08-23
Abstract: The substance to be inserted is contained in a reservoir, surrounded by parallel cylinders connected to it and outlets and containing pistons. Top and bottom endless tracks enclose the central reservoir, and the angle between their plane and the cylinder axes can be varied, thus causing the reservoir and the cylinders to rotate about the vertical reservoir axis. The machine is particularly for handling semiliquid commodities such as jam. Each piston is connected to the end of a pin protruding radially between top and bottom tracks, and which carries a sleeve sliding axially on it to a position in which it can be locked. Each sleeve carries slides working against the tracks.

Title: Paving stones with hexagonal shape - interlocked to increase load carrying capacity and improve appearance
IPC: E01C5/06
Filed: 1975-01-11
Abstract: Paving stone made of concrete or similar setting materials, consisting of a number of individual elements which, in their plan view have the shape of a regular hexagon and are so arranged w.r.t. each other that >=1 side of the hexagon mates with two elements adjacent to each other. The novely is that at least three, and pref. four or more individual elements, are arranged in at least two rows next to each other so that one element always has a corner located in the angle formed by the other two elements. When the elements are located in two rows, the rows may contain the same number of elements or one row may contain one less element than the other. The stones are interlocked so that they are highly resistant to horizontal stresses, e.g. arising from motor vehicles, and they also possess a good optical appearance.
Patent DE-2503277-A1 (DE)
Title: Moving piston in pneumatic cylinder - by equalising pressures on both sides of piston before reverse movement
Inventor: BRUEHL PETER
IPC: F01B11/02
Filed: 1975-01-28
Abstract: The arrangement is such that, before reversing the direction of piston movement, the pressure on the pressurised side of the cylinder is admitted to the pressure-less side so as to equalise the pressures fully or nearly fully. Subsequently the other side of the cylinder is fully pressurised, and, as the piston moves, the non-pressurised side is allowed to exhaust to atmosphere. Pressure equalisation may be achieved by using a duct in the control valve to connect the two sides of the cylinder.

Title: Ball and socket joints surface hardened by nitriding - or nitrocarburizing, then austenized and oil quenched
Inventor: SCHMIDT JENS
IPC: C21D9/36
Filed: 1975-06-18
Abstract: In the mfr. of a steel component with long life, esp. part of a link rod ball and socket joint, the novelty is that after shaping the part an edge zone is treated below the transformation temp. in a nitriding medium to avoid pitting in service. This is followed by an austenising treatment. The edge zone is pref. treated at 400-600 degrees C, in a medium providing both C and N2 for the nitro-carburising of the part, followed by austenising and hardening in the absence of O2. The resulting structure pref. contains 10-40 vol.% residual austenite and martensite contg. nitrogen, possibly with a thin surface layer contg. Fe, iron oxide and residual austenite. The process is used for the surface hardening of balls, ball seats and links for ball and socket joints.

IPC: G03B1/12
Filed: 1975-07-05
Abstract: Photographic or cine camera comprises a spring-wound motor (4) which is tensioned during its movement by means of a cover portion. The latter and the drive spring of the motor coact with each other via a locking member (7) which, when insufficient driving energy is stored in the spring, extends into the region of movement of the cover portion to prevent it from closing. The locking member is pref. a two-armed rotary lever of which one arm (7a) is spring-biassed towards the outer periphery of the drive spring, while its other arm (7b) conacts with an attachment (3b) on the rear cover (3). also on the rear cover may be a toothed segment (3a) which engages the motor via a gear (9) and which tensions the motor during movement of the cover. The operating of the locking device allows the user to dispense with lengthy considerations with regard to the driving energy, as the film can be exposed over its whole length when the rear cover can be closed.

Title: Frame synchronisation for PCM TDM telephone network - has two monostable flipflops for fixing sync. and waiting times
Inventor: MURASOV VADIM DIPL ING
IPC: H04J3/06
Filed: 1975-09-25
Abstract: The frame synchronisation, for a PCM TDM telephone network, synchronises the counter in the receiver. Two monostable flipflops are used to determine the time occupied by synchronisation and the waiting time. Both flipflops are driven over into their unstable states by control signals. They remain in these states for specified times related to the duration of the pulse frame. Control signals are applied to the set input of the flip flop that determines synchronisation and to the reset input of the counter in the receiver at specified moments.
