Title: Water soluble phthalocyanine dye prepn. - by reacting phthalocyanine sulphonic acid chloride with prim. or sec. amine contg. beta substd. ethyl:sulphonyl gps.
Inventor: SPRINGER HARTMUT DIPL CHEM DR
IPC: C09B47/26
Filed: 1979-02-20
Abstract: Water soluble phthalocyanine dyes are made by reacting a phthalocyanine cpd. contg. >=1 sulphonic acid chloride gp. and opt. >=1 sulpho gp., with (a) a prim. or sec. amine contg. >=1 beta-substd. ethylsulphonyl gp. or >=1 vinylsulphonyl gp. and opt. (b) a prim. or sec. amine of the aliphatic, heterocyclic or aromatic series, in the presence of (c) a pyridine sulphonic acid or pyridine carboxylic acid. The process gives water soluble phthalocyanine dyes without the use of pyridine as catalyst, which is toxic and malodourous. The prods. are useful for dyeing and printing wool, silk, linear polyamides, leather and (esp) cellulose materials such as cotton and regenerated cellulose.

Title: Locking device for rotor of distributed pole turbo-generator - has ring key on rotor body fitting against locking ring connected to retaining ring by bayonet joint
Inventor: ZAGORODNAJA GEB POLUEKTOVA GAL
IPC: H02K3/51
Filed: 1979-04-09
Abstract: The locking structure for rotor end winding (e.g. a turbo-generator) comprises a retaining ring (1) to embrace the rotor end winding and a locking ring (3) to prevent the retaining ring from shifting axially with respect to the rotor body. Both rings are also secured by shrink fitting.

Title: Electrically conductive fluid surface tension measurement - uses electrical contacts to record flow through capillary tube
Inventor: BUETTNER ULRICH ING GRAD
IPC: G01N13/02
Filed: 1979-04-20
Abstract: Gas at constant pressure is blown into the fluid through a capillary tube. The rate of flow of air and the size of the bubbles is a function of the surface tension of the fluid. The bubbles are guided into a funnel and electrodes fixed across a known diameter record the presence or absence of the conducting fluid and hence measure the gas flow. Alternatively the capillary outlet may be downward and the electrodes attached directly across the outlet. The measurement can be used as an indirect measurement of concentration. The tube may be made of glass, metal or plastics with an inner diameter from 5 to 8 mm. The bubbles are initially spherical and become elongated as they enter into the narrowed section of the measurement tube.

Title: Tunnel or gallery reinforced concrete tubbing ring - has several half sections arranged in homologous fashion with end faces permitting versatility
IPC: E21D11/04
Filed: 1979-07-12
Abstract: Tubbing rings made of reinforced concrete are used for lining mine galleries or tunnels. The geometrical location of external conicity of the rings is a constant-interval cylinder, while that of internal conicity is defined by two spheres with generatrices forming the intersecting lines of bounding surfaces. The ring end faces form equal angles to the plane of symmetry extending radially to the tunnel axis. The axis intersection in this plane cuts that through the tunnel axis at right angles. It also passes symmetrically through two opposite lengthways gaps in two adjacent tubbings. It is divided into two homologously sited halves, fully congruent in joint gap geometry. The number of different tubbing shapes is reduced.

Title: Thermoelectric generator - functionally combined with heat exchanger has higher overall efficiency
Inventor: BOJAK KURT DIPL ING
IPC: H01L35/00
Filed: 1980-02-12
Abstract: A thermoelectric generator, esp. for the water electrolysis, is functionally coupled with a heat exchanger system so that the hot medium heats the hot junctions and the cold medium cools the cold junctions. The heat flow, compounded of conductive heat and Joule's heat, is thereby used to heat the low temp. medium. The heat flow along the legs from hot to cold junction which contributes to the poor efficiency of a thermoelectric generator is now turned to good effect.

Title: Laying siphon duct in underwater trench bottom - involves floating and initially partially lowering first section hung on posts
Inventor: GAISER HEBERT
IPC: F04F10/00
Filed: 1980-04-25
Abstract: Siphon pipes, floated into position, are hung on frame posts driven in at intervals, before sinking into the bottom, in laying siphons in the bottom of trench under water. The siphon is produced in sections on land, and the first section is floated in, hung on the posts, and lowered to a point just above the trench bottom. The following section is attached to the first, which is then lowered to the bottom, and the siphon is drawn into its final position. A number of sections may first be interconnected and hung so as to hover on the posts, just above the bottom. This enables siphon ducts to be laid, even when there is not enough adjacent land for full-length assembly.

Title: Switch operated by pressure medium - has switch contacts close to one another to prevent tipping of switching bridge
Inventor: PRCHLIK JIRI
IPC: H01H35/34
Filed: 1980-07-30
Abstract: The pressure switch (10)-suitable as an oil pressure warning switch for monitoring the lubrication of an i.c. engine-consists of a metal housing (11) with a connecting nipple (12) to which, the braking system feed line is connected a central bore (13) in the nipple allowing the pressure medium to flow to the diaphragm chamber (14). This chamber (14) is contained by the metal housing (11) and a membrane (15). The membrane (15) is fixed in the housing (11) by a seal (16) and metal plate (17). On the other side of this plate (17) is the switch chamber (18) closed in an insulated housing (19) which is sealed and contains two moulded-in contact pins (22,23). These pins (22,23), extend into the interior of the switch chamber (18) from the outer chamber (24) and have a contact plate (25,26) riveted to each one respectively. A spring-loaded contact bridge (27) connects the contact plates (25,26), and is itself activated by a thrust bolt (28), which in turn is moved by the diaphragm when pressure is applied to it by the pressure medium. The interior construction of the contacts ensures that the bridge does not tip sideways and cause bad contact.

Title: Video signal processor for TV receiver - detects black component and has suppressor circuit for period exceed line suppression interval modifying wave
Inventor: OKADA TAKASHI
IPC: H04N5/14
Filed: 1980-08-18
Abstract: The video signal processing circuit is for use on a television receiver, where the signal level is detected which is nearest to black during the video period. That level is chosen as the cut-off level of the cathode ray tube and used to prevent fluctuations in the black section of the image. The input video signal is fed to a suppressor circuit (2) for a period which is longer than the normal image line suppression interval. During that period it is altered in a predetermined direct voltage level higher than the threshold level, providing an output signal with modified wave form. The suppressor circuit(2) is followed by a minimum level hold circuit (4), a comparator (5) and a level fixing circuit (6).

Title: Electronically programmable read-only memory device - with increased integration density and data retaining property
Inventor: KOMORI KAZUHIRO
IPC: G11C16/04
Filed: 1980-09-26
Abstract: Semiconductor memory device has a persistent memory element with a first layer for trapping charges and a second layer, on this, to which a random voltage can be applied for trapping the charges in the first layer. The novelty is that the first and second layer are covered with a Si nitride film or a polycrystalline Si film. The first and second layers pref. consist of polycrystalline Si. The memory is surrounded by a matrix with a transparent window. A section contg. a persistent memory cell is covered with a Si oxide film and a contact window is formed in this on a semiconductor zone. A Si nitride film and phosphosilicate glass film are formed consecutively, overlapping the Si oxide film and covering the cell section. Pt. of the glass film is etched away to form a contact window and expose pt. of the Si nitride film, which is also etched away, then the Si oxide film is etched away using the Si nitride film as mask. Alternatively, a poly-Si film is formed, overlapping the Si oxide film and covering the cell section, then pt. of this and the underlying Si oxide film are etched away consecutively and the poly-Si film is oxidised to form an oxide film covering this. The device is used as electronically programmable read-only memory (EPROM). The integration density and data retaining properties are improved.
