Title: Corrosion prevention in acid natural gas pipes - by addn. of a phosphate ester to the gas stream
Inventor: PETER SIEGFRIED PROF DR
IPC: C09K8/54
Filed: 1975-06-27
Abstract: Corrosion in acid natural gas delivery pipes, esp. in presence of H2S and Cl ions is prevented by addn. of phosphate esters to the gas stream at the top of the underground deposit. Slow hydrolysis of the esters forms phosphoric acids which give an adherent phosphate coating on the metal surface and prevent or retard further corrosion. Pipes are protected even under severe corrosive conditions e.g. in areas intermittently by polysulphide solns. formed by adsorption of S impurities in the gas in aq. amine solns. In an example, 0.2 wt.% tri-n-butyl phosphate is added to an aq. soln. contg. 1 wt.% NaCl and CaCl2 in concn. of 150 degrees dH. A steel strip is half-immersed in the soln. and heated for 200 h. at 140 degrees C in an autoclave under pressure of 5 bar H2S and 45 bar CO2. No signs of corrosion or wt. loss are observed.

Title: Information storage in linear storage element - with direct access to individual longitudinal sections differently magnetizable as storage cells
Inventor: DROESEL HERMANN
IPC: G11C8/00
Filed: 1975-07-25
Abstract: Information storage in linear storage element has direct access to individual longitudinal sections. They are differently magnetizable as storage cells. Pulses are produced with an intensity and direction suitable for the magnetization required in one or more controlled longitudinal sections of the storage elment. Pulses with a strength not sufficient for the magnetization required move toward each other from both ends of the storage element and along the storage element. The delay of one pulse compared to the other is such that the pulses are superimposed in the controlled longitudinal sections of the storage element to a pulse of sufficient strength.

Title: Self cleaning dentists inspection mirror - has rotating wiper and air jet across mirror surface from central wiper
Inventor: GREUTERT ALBERT
IPC: A61B1/253
Filed: 1975-10-15
Abstract: The circular mirror (3) is silvered on the back (5) and is mounted on a hollow handle (1, 7) along which compressed air can pass to a hub (9) in the centre of the mirror. The air coming up through the hub passes outwards between curved vanes. It is deflected downwards, across the mirror surface, by a cap (11) above the vanes. The hub carries a flexible rod (10) which lies within 0.3 mm of the mirror surface. As the air current between the vanes rotates the hub - at pref. 20,000-40,000 r.p.m. the rod wipes away droplets from the mirror. The air current across the mirror surface removes mist too fine for the wiper. The rotation can be obtained from reaction jets in the wiping rod itself.

Title: Metallic prods. showing thermal recovery - prepd. from alloys showing enlarged martensite-austenite hysteresis loops
Inventor: BROOK GREVILLE BERTRAM
IPC: F16B1/00
Filed: 1976-02-02
Abstract: Mfd. prod. showing thermal recovery is made of a metallic compsn. showing an enlarged martensite/austenite hysteresis loop. When the prod. is deformed, while it is the martensitic state, the deformation remains. On heating to a temp. at which the state is austenitic, the prod. tends to return to its undeformed state. The prod. has an elongation at break of at least 5%, and is stable during storage at 23 degrees C. The Ms temp. of the metallic compsn. is below ambient temp. The compsn. returns to its normal hysteresis loop when it is heated to a temp. above the As temp. of the enlarged hysteresis loop.

Title: Elastic seal ring for concrete pipe coupling - has separate locating flange and sealing lip attached to anchor ring by thin walled sleeve
IPC: F16L17/025
Filed: 1976-02-03
Abstract: A plug-in coupling for concrete pipes is provided with a seal ring which is located in an internal groove (4) inside the coupling sleeve. The anchor flange (6, 8) of the seal has an integral reinforcing ring (7). when the seal ring is installed, the flanges (8) are bent over so that they produce an axial location. The rounded seal lip (12) is attached to the anchor ring (6) by a thin walled sleeve (10). When the inner tube is pushed into the coupling sleeve, the seal lip is rolled over and displaced into a seal lip groove in the coupling sleeve. Thus the seal is wedged between the inner and outer tube of the coupling assembly.

Title: Refuse and sludge processing system - uses hot flue gases from incinerator for sludge drying and warm water prepn.
Inventor: FEHLMANN HANS BEAT DIPL ING
IPC: C02F11/13
Filed: 1976-09-01
Abstract: A system for processing refuse with combustible components and of sludge from the activated sludge treatment sections of sewage produces hot flue gases by combustion of a part of the refuse material. These gases are used to dewater the sludge which cools them and converts them to gas with a high steam content. The latter is cooled to turn the steam into condensate and purified. System eliminates environmental pollution by odours. The thermal overall efficiency is high and the operational costs low. Both the compost (dry sludge) and the warm water can be used for agriculture purposes.

Title: Motor speed controller for sewing machines - using variable leakage flux transformer with one core limb under control of pedal
Inventor: SOEDA KATSUZI
IPC: H02P23/00
Filed: 1976-09-02
Abstract: The principal application is to the smooth and contact less speed control of motor driven sewing machines. A variable leakage flux transformer (3) has a primary winding (1) connected to an a.c. supply (4), and a secondary winding (2) connected to the motor (6). A movable core limb (9) is connected to a lever, for example a foot pedal. For a small gap between movable limb (9) and main core a large voltage is induced in the secondary winding resulting in high torque conditions on the motor which starts. By increasing the gap between cores the voltage, and hence the running speed can be controlled. The two winding transformer also provides electrical insulation between supply and motor which gives an added measure of safety to the operator.
