Title: Tube prodn. sheet metal blanks on mills - using preliminary measurement of blanks to help eliminate wastage
Inventor: WERNIK ALEXANDR B
IPC: B21C37/083
Filed: 1973-10-10
Abstract: Pipes a re-produced from sheet metal blanks on a mill by feeding the blanks in a progression following each other, measuring the length of each blank, leaving in the progression pairs of blanks whose differences in length is less than a preset value and removing unpaired blanks to storage where they will be paired up with other unpaired blanks in the progression. The edges of the blanks are then treated to form a half cylinder, the half cylinders are welded together to form pipes and the edges of the pipes are trimmed. There is a reduction in waste metal (trimmings) and the lengths of tubes produced from the same amount of metal can be extended. There is a saving in both floor space for laying the blanks separated out of the sequence and in time, needed to return them into sequence when compiling the pairs.

Title: Fluid seal for rotating shaft - has guide ribs to promote return flow of fluid along shaft irrespective of rotation direction
Inventor: PAFFRATH JOSEF
IPC: F16J15/3244
Filed: 1973-12-22
Abstract: The tapered section on the fluid side of the sealing lip has four equal sectors, of bearing sets of curved radial ribs which pump the fluid. The ribs of adjacent sectors are curved in the opposite sense so that the seal is functional for both directions of shaft rotation. Where the curved rib sections meet, a gap is provided so that the fluid is free to flow. When the curved ribs are placed on the dry side of the sealing lip, an air stream is produced which counteracts any leakage through the seal. The seal is made of a flexible material, and is stiffened by 'L' section and coil spring metal inserts.

Filed: 1974-02-07
Abstract: Prim. and sec. amines are isolated from aq., organic and aq-organic solns. contg. them by distn., rectification or extn. in the presence of CO2. Reaction with CO2 decreases the volatility of prim. and sec. amines (while the volatility of H2O and other organic cpds. remains unchanged) and decreases their solubility in organic solvents, so that sepn. can be effected under less severe conditions. In the case of rectification, CO2 is pref. circulated continuously through the system. In the case of distn. or extn, the soln. is pref. satd. with CO2 before treatment.

Title: Force pickup for structures - measures load forces applied to chassis of vehicles or landing gear of aircraft
Inventor: KAMPF HERBERT
IPC: G01G3/14
Filed: 1974-02-08
Abstract: The force detector comprises at least one stationary elastic component deformed by the applied forces, and sensing element whose one end is clamped and the other connected to the above and deformed with it, so that it delivers test signals.

The element transmitting to the sensing element deformations of the elastic component is an eccentric whose axis of rotation is at leas approximately parallel to the sensor axis. Its rotation changes over the sensing element from its test to rest positions.

Title: Electrophoretic pptn. of binders from conducting preparations - gives powders suitable for paint use
Inventor: MARX MATTHIAS DIPL CHEM DR
IPC: C09D5/03
Filed: 1974-03-01
Abstract: Binders with film-forming temps. of 40-240 degrees C are pptd. from a dil., electrically-conducting preparation, below the film-forming temp. by applying an electric potential. Prod. is removed, pref. continuously, from electrode as powder and is opt. dried or ground. Moderate temps. used avoid risk of premature cross-linking. Cleaning out mixing, grinding or sieving equipment is unnecessary. Additives usually needed in pptn. processes to give matl. in non-tacky, non-agglomerating form are eliminated. In contrast to spray-drying, prod. is obtd. in granular form suitable for paint use. Non-ionic additives, including pigments, can be co-pptd. if mixt. is suitably homogenised.
Patent DE-2414475-A1 (DE)
Title: Hot strip rolling system - producing tapered leading crop end for easy filing into reel triblet
Inventor: ROTTER FRIEDRICH DIPL ING
IPC: B21B1/26
Filed: 1974-03-26
Abstract: Strip is rolled on a multi-stand wide strip rolling mill and finally coiled up on a reel. When a new strip is being started, the rolls of one stand, pref. one of those normally running idle just ahead of the reel, are screwed down to below the normal strip gauge. When a strip length equal to the circumference of the triblet of the reel has passed, the gap is quickly increased above the strip gauge. This facilitates the filing of the leading strip end into the reel and enables much thicker strip gauges to be coiled in a reel. The crop end is thereby reduced from a conventional 10 m and over to 2 m or a max. of 5 m. All elements of the reel are stressed less heavily and shock loads are eliminated.
