Patent DE-2438433-A1 (DE)
Title: Satellite signal transmission method - signal bursts from ground stations are combined in TDM unit provided with preamble
Inventor: ZILG JOCHEN DIPL ING
IPC: H04B7/212
Filed: 1974-08-09
Abstract: Signal bursts in the satellite are staggered in time, combined in a frame and re-transmitted (TDMA). In order to obtain an emergency access, a ground station sends an emergency access signal which is evaluated for allocation of the phase for the ground station signal burst. Transmission phase or the emergency access signal repetition frequency is derived from the reference station clock pulse generator synchronised through the reception side. Clock pulse generators in the non-reference stations are synchronised by the reference signal bursts before, or at least during, the emergency access operation. This clock pulse generator synchronisation is carried out also during further burst transmissions.

Title: Railway track rail screw fixture on substructure - is used in conjunction with permanently inlay in hole in wood with internal thread
Inventor: KRACKE HARALD
IPC: E01B9/14
Filed: 1974-10-24
Abstract: The rail fixture, on concrete of wooden sleepers, or on permanent way structures without ballast, comprises screws turned into a hole in the wooden sleepers or into a wooden plug, through the underlay plates, if necessary with bracing clamps for the rail. Inside this hole in the wooden material, which is suitably widened, there is an inner sheath made of a permanently elastic material, pref. plastic, with an inside thread corresponding to the outside thread on the screw. The plastic used is preferably of low viscosity before hardening, so as to penetrate small hollows and gaps in the sidewalling of the hole before it has set hard. Acryl resin is a suitable material for this sheathing, with a powder additive to accelerate hardening.

Title: Longitudinally welded tubular mast production system - has sheet material bent into rough tube form and welded whilst under compressive stress
Inventor: ROSENHAMMER HANS
IPC: B21C37/08
Filed: 1975-01-25
Abstract: The system is for production of longitudinally welded steel tubular masts, in partic. light or lamp standards from steel sheets. The steel sheet sections (22) are bent around until the edges which are to be welded together are situated opposite one another. The whole partially bent unit is then tensioned throughout its length in a tensioning device and compressed to a tube whilst the longitudinal weld head is formed along its entire length in a single operation (6). The compressive force used is sufficient to produce a straight gap to be in filled with weld material. The tube is held between two sets of Vee clamps (15, 21) which automatically close it.

Title: Riser pipe assembly - for offshore drilling platform prefabricated on shore as reinforced bundle and floated on site
Inventor: VOGEL RUDOLF DR
IPC: E21B43/017
Filed: 1975-02-08
Abstract: Riser pipes for offshore drilling platforms are prefabricated at an onshore site as a bundle of pipes, preferably in a square corss-sectional pattern, which is reinforced by cross bulkheads and diagonal traces. The pipe bundle is so designed that it can be floated to its offshore site. The sea floor end is equipped with a reinforced circular tray which extends beyond the square pattern and rests on the bottom of these sea when the pipes have been driven in. The greater stiffness of the complete bundle permits a much thinner wall thickness of the pipes, hence considerably savings of material and less transport costs.

Title: Synchronising arrangement for oscillators - compares oscillation frequencies and phase with sinusoidal oscillating signal to derive control quantity
Inventor: ZILG JOCHEN DIPL ING
IPC: H03L7/12
Filed: 1975-02-28
Abstract: An arrangement to synchronis the output of an oscillator with a sinusoidal oscillating signal. Signal oscillation and oscillation frequencies and phases are compared in order to derive a control quantity for the oscillator control. The oscillator is operated over a specified range for its first and repeated synchronisation, until the difference between the two frequencies falls below a specified value, and then the synchronisation control is applied. During the oscillator frequency run, and depending on the consecutive operating periods, response sensitivity for detection of the received signal with superposed interferences is gradually increased in steps, starting from a minimum sensitivity.

Title: Solids fed into vessel contg. flammable liq. through inert gas cloud - flowing into and away from vessel
Inventor: MACURA PAUL DIPL ING
IPC: B01J8/00
Filed: 1976-03-29
Abstract: A method of feeding solid, powdery, granulated or crushed products into a reaction vessel which contains a combustible liq. and is rendered inert to prevent risk of fire is as follows. The solid materials are introduced through a funnel and a following feed tube into the reaction vessel; an inert gas is blown through nozzles situated at the transition between the funnel and the feed; some of these nozzles project the inert gas down towards the reaction vessel, while other nozzles project it upwards the funnel. Inert gas expansion equipment in the funnel reduces the gas pressure, while other equipment reduces the excess pressure in the reaction vessel. A full inert gas blanket is produced between the incoming solid materials and the flammable liq. e.g. solvent, inside the vessel, thus preventing any vapour from this solvent or other flammable liq. from ascending and causing an explosion or fire risk.
Patent DE-2620157-A1 (DE)
Inventor: HOFFMANN GUENTER DIPL ING
IPC: H05B3/52
Filed: 1976-05-07
Abstract: The method relates to a labour-saving uniform embedding of a heating element, which is bent in a U-shaped manner, into an outer pipe. The heating element (1, 6, 8) is at both its leg ends connected detachably to interlocking connectors (11) and the two legs are drawn up in guide pipes (3) of a device (3, 4, 7, 11). The device (3, 4, 7, 11) with the heating element (1, 6, 8) is then pushed from above into the outer pipe (5), the cavity of the filling pipe (4) is filled with insulating material (2) and the outer pipe (5) is subjected to vibrations so that the insulating material (2) slides downwards through a trickling bottom (7) and surrounds the lower part (8) of the heating element (1, 6, 8). This is clamped securely in the insulating material (2) by pressing together the lower end of the outer pipe (5). The parts (3, 4, 7) of the device are gradually lifted out of the outer pipe (5), the latter being filled, while being vibrated, with the insulating material (2). <IMAGE>

IPC: F16K3/26
Filed: 1976-05-21
Abstract: A 3-way solenoid operated piston valve has a tubular valve body (1) which is located inside the magnetic coil (3) with one end. The valve inlet is axially through the free end of the valve body tube. The two outlet ports (20, 21) are located radially side by side near the operating coil mounting sleeve (13). The valve piston (2) has a hole (23) which allows a medium flow from the axial end face (18) to a ring chamber between piston and valve tube. A compression spring (19) locates the piston in a position where the flow is through the piston cross hole to outlet port (21). When the solenois is energised, the piston is retracted and the medium flows directly to the outlet port (20).
