Patent DE-2456141-A1 (DE)
Title: Pipe laying barge for variable depths - with adjustable pivoted support for ensuring correct angle for pipe sections
Inventor: BRUNS GUENTHER
IPC: F16L1/20
Filed: 1974-11-27
Abstract: The pipe laying barge has a special working jig pivotted about a transverse axis at the stern, and supported by an array of hydraulic rams to set the jig in the desired inclination. Prefabricated pipeline sections, as long as the jig are stacked on the barge alongside the jig and are rolled in turn onto the jig. After raising into the desired angle, which depends on the depth of water into which the pipeline is being laid, the section is welded onto the end of the pipeline, being held in a clamp at the sterm of the barge. Rollers and brakes ensure that the section is paid out smoothly and without damage. A catamaran hulled the seabed with special hoists.

Title: Armoured flexible conveyor - has trough sections with rigid plates and universal joints allowing play
Inventor: PENTITH GERALD RICHARD OLDHAM
IPC: B65G19/28
Filed: 1974-12-28
Abstract: The conveyor has a trough in sections pivoting in relation to each other, and each section has on one sidea rigid plate extending upwards. Adjacent ends of such plates are joined by top and bottom links, one in the form of a universal joint and the other allowing some play. On the side opposite to the rigid plates the sections are joined by further link allowing play. Thus distance between sections and plates can be varied for a limited amount by means of these links. The universal joint can be of the ball-and-socket type, and all universal joints can be situated in the same position in relation to the trough.

Title: Regulator for electric cooking plates - has temp. sensitive resistor in blocking oscillator responding to condensed vapour
Inventor: FISCHER KARL
IPC: H05B1/02
Filed: 1975-09-06
Abstract: The regulator, for electric cooking plates, consists of a sensor in the lid of the cooking pot and a transmitter to transmit a switching signal to a receiver mounted on the cooker itself. The receiver then switches off the heating supply. The transmitter is supplied from a battery (33). The sensor responds to the heat released by condensing vapour from the cooking pot and triggers the transmitter at a given point. The transmitter and receiver are not connected by wires as in 2161371. The regulator is simplified and made more reliable if the sensor comprises a temp. sensitive resistor connected into a blocking oscillator.

Title: Wedge-like tool for shearing off beads on welded plastics - for saving time and improving quality of weld joint
Inventor: BECKER HELGE
IPC: B29C65/20
Filed: 1975-10-14
Abstract: The tool for shearing off welding beads or for restricting the protruding welding bead on welded plastic components can be heated. Pref. the cutting edges are concavely shaped according to the material to be worked, and remove the welding bead only to such an extent as to provide a planar surface between the connected workpieces after they have cooled and the weld seam has collapsed. If the bead is to be sheared off or limited in width perpendicularly to its main dimension, heated wedge-like tools operating on both sides allow more sensitive movement towards each other, with closer abutment without risk of machine damage. The tool requires less energy, roughens the surface less, and provides greater weld strength.

Title: Combined lawn mower and weed remover - incorporates pick up roller underneath discharge roller with fixed spikes
Inventor: KIRSCHENPFAD HUGO
IPC: A01G1/12
Filed: 1975-11-14
Abstract: Lawn mower incorporates two superimposed rollers with steel rods. The one roller has curved steel claw-shaped rods sharpened at the tips, for eliminating weeds. The second roller also has steel rods round it. The second discharge rolle has a gear wheel at one end, and is joined by gear wheels to the gear wheel of the pick up roller. The discharge roller revolves at roughly four time the speed of the pick up roller.

Patent DE-2604751-A1 (DE)
Inventor: KUSCH ANDREAS DIPL ING
IPC: C07C69/80
Filed: 1976-02-06
Abstract: The carboxylic esters to be purified are in particular esters of aromatic dicarboxylic acids with aromatic alcohols of 3-13 carbon atoms, which are obtained by esterifying using sulphuric acid as a catalyst, neutralising with alkali and driving off the excess alcohol with water vapour. The crude ester, heated to 140-160 DEG C, is admixed with 10-20% by weight of deionised water, so that the temperature falls to 90-100 DEG C. The crude ester is then treated with the aqueous alkali formed in order that electroconductive impurities or concomitants may be removed. The water which has been introduced is then removed from the two-phase mixture by renewed heating and vacuum distillation. The neutral ester left behind is filtered to remove the suspended concomitants. The process is simple and economical to carry out with a relatively short treatment time, and produces purified esters which are suitable for use as dielectrically high-grade plasticisers for plastics.

Title: Sealing installed gas pipes - by pressing foamed swelling agent, pref. admixed with glycerol, into pipe network
Inventor: HOFMANN PHILIPP DR RER NAT
IPC: F16L55/164
Filed: 1976-03-06
Abstract: Installed gas pipes are sealed by pressing a swelling agent into a predetermined section of a pipe-network. Novelty consists in foaming the swelling agent before pressing into the pipes of the pipe-network section. Swelling agent may be foam-former itself or a mixt. of standard foam-formers and swelling agents, opt. mixed with a diluent, e.g. glycerol. Advantageously, foam-former itself is used as swelling agent, with addn. of glycerol. Glycerol is hygroscopic, bonds any water in seal and prevents loss in swelling activity through evaporation of the water. Foaming reduces surface tension of swelling agent and facilitates swelling agent penetration into pores and capillaries. Seal is safe and permanent.

Title: Welding of steels of different compsn. - facilitated by deposition of intermediate layer of ferritic steel (OE 15.2.78)
Inventor: AUGUSTIN HUBERT
IPC: B23K9/23
Filed: 1976-04-13
Abstract: The rails of a railway junction are bolted to distance pieces which are welded to the centre piece or frog. Since the distance pieces are usually made from a low C steel and the frog is made of a heat treated alloy steel it is not possible to weld the two materials directly to each other. To overcome this problem an electrode of ferritic steel having an equivalent carbon content of 0.20% is used to deposit a layer of weld metal on the surface of the frog. The frog is then welded to the distance pieces with the weld fillets. The equivalent C content is calculated from the amt. of other elements present such as Mn, Cr, Ni etc.
