Title: Clamping collar for hinged glass pipe joint - has seal ring contacting clamp collar along two lines on angled faces
IPC: F16L23/18
Filed: 1976-05-05
Abstract: The joint for parts of pipework includes a clamping collar with two annular faces on the side towards a flange on the pipe end. These faces include a different angle with the centre line and contact the seal ring, which contacts the flange at one point, in two points. This ensures uniformity of the forces acting on the flange. The seal ring remains aligned centrally and allows adequate flexibility. The joint is specially suitable for glass pipes. The pipe (2) has a flange (3) with a truncated cone face (13). A seal ring (6) contacts it at point (14). The clamping collar (7) has a cylindrical (10) and a truncated cone (9) face which contact the seal ring at the points (12, 11). Bores (8) are used for the clamping bolts.

Title: Flame cutting gaps in the ends of large dia. pipes - to prepare joint surfaces suitable for butt welding
Inventor: KOUKAL ANTON
IPC: B23K7/00
Filed: 1977-05-18
Abstract: Butt welding profiles consisting of bell-shaped gaps are cut in the ends of pipes or workpieces with a circular cross-section. The shape of the gap is determined by the radius at the root of the gap sides and also the slope of the flanks of the gap. A cutting burner is located under the end of the pipe so the axis of the burner flame is inclined w.r.t. the end of the pipe. Either the pipe or the burner may be rotated to form the gap, and the burner may use a conventional nozzle; or a nozzle forming several small jets of flame; or a curved slot nozzle producing a curved flame with a large radius of curvature at 90 degrees to the direction of the flame.

Title: Float operated valve for water cisterns - has pilot valve acted on by float to change pressure balance in main valve
Inventor: DENKENA KARL-HEINZ ING GRAD
IPC: F16K31/34
Filed: 1977-06-20
Abstract: A float-operated valve is designed for operation esp. with water cisterns. It comprises a main valve (9, 10), biased into the closed position by supply pressure acting through a balance chamber (6) connected to the water supply (7) through a pilot valve (5). The float acts on the pilot valve. On release of water from the cistern the float drops and opens the pilot valve. Water then flows from the balance chamber and causes the main valve to open under supply pressure. On filling of the cistern the float closes the pilot valve and causes supply pressure to close the main valve.
Patent DE-2732366-A1 (DE)
Title: Explosion resistant pressure vessel composed of concentric spheres - has radial prestressed struts to absorb alternating shock wave energy
Inventor: BORSDORF HEINZ DIPL ING
IPC: G21C13/00
Filed: 1977-07-18
Abstract: The parent patent describes an explosion-resistant pressure vessel composed of concentric spheres; these are prestressed by radial struts, which thus transmit thrust to an innermost pressure shell suited concentrically to the spheres. In the patent of addition pressure shells and anti-burst shells are arranged concentrically and in such a sequence and number and with such an arrangement of radial prestressed spacers that sufficient load reserve exists to retard forces acting from the outside inwards. If the outermost anti-burst sphere is ruptured, the remaining system possesses sufficient strength while conversely if the innermost sphere is ruptured the remaining system also possesses sufficient strength. The system is equally effective against internal and external forces, i.e. it resists a suction force following upon a pressure wave.

Title: Azido:hydrin prodn. from di:ol and ortho-ester - then reaction with azido:silane and hydrolysis, useful as intermediates for e.g. oxazolidinone derivs.
Inventor: HARTMANN WILLY DR
IPC: C07D319/06
Filed: 1978-03-31
Abstract: Prodn. of azidohydrins comprises first reacting diols of formula (I) and orthoesters of formula (II) (or the corresp. ketone acetal) to give heterocycles of formula (III). These are then reacted with an azidosilane, opt. in presence of a catalyst and inert organic solvent, to cpds. (V) which are then hydrolysed. In the formulae, R1-6 are each H or opt. substd. alkyl, cycloalkyl, alkenyl, aralkyl or aryl. R3 and R4 may also be halo, CN, alkoxy or aryloxy, or R1+R2 and/or R5 + R6 or R1 + R5 and/or R2 + R6 may complete an opt. substd. ring; n = 0 or 1; R7 = H, opt. substd. alkyl, cycloalkyl, alkenyl, aralkyl or aryl, or alkoxy or alkoxycarbonyl; and R8-10 are each opt. substd. alkyl, alkenyl, aralkyl or aryl. Alternatively, reaction of (III) and the azidosilane produces a cpd. of formula (IV) which is converted to (V) by heating. The azidohydrins are intermediates e.g. for aminoalcohols used to make oxazolidinone derivs. (useful as corrosion inhibitors, antistatics, pharmaceuticals and pesticides), and for acetyl-choline analogues.
Patent DE-2816263-A1 (DE)
Title: Earth fault monitoring system for cable networks - uses fifth harmonic current detector with heavy fundamental suppression
Inventor: RIPKA KARL WOLFGANG DR TECHN
IPC: H02H3/16
Filed: 1978-04-14
Abstract: It is well established that an earth fault in a cable network leads to a marked increase in fifth harmonic current. The detection of this current, through a current transformer (T), is made more sensitive by heavy damping of the fundamental frequency. The required damping is achieved by adding a series capacitor (C2) between the parallel tuned filter (L, C1) and a bridge rectifier (G) which passes a fifth harmonic dependant signal to a trigger circuit (MT). The addition of the series capacitor increases the damping of the fundamental of the power supply frequency. The inductive elements (L) of the parallel filter can be combined with the inductance of the transformer winding.

Title: Seed germination acceleration e.g. in malting - by treating seed or cereal grain with oxygen
Inventor: DAVIDSON MAXWELL WINGATE
IPC: A01N59/00
Filed: 1978-06-20
Abstract: New process for treatment of seeds or cereal grains comprises treatment with a gas whose major component is oxygen. Used for hitting or pregermination of seeds or cereals and also useful for mass germination of cereal grains (e.g. barley) in malting. Appts. for germination of seeds or cereal grains comprises a container for a layer of seed or grain. The container is attachable to an oxygen or gas container, so that the gas can be passed through the layer of seed or grain. The container is also connected to a water supply to soften the seed or grain layer and to a drying device. The new process gives uniform and rapid germination, so that in the seedlings are at a vulnerable stage for a shorter time, and the total time of the crop in the soil is reduced. In malting, the time for the malting process is reduced.
