Title: Stable self-emulsifiable epoxy resin solns. - contain quat. ammonium gps. obtd. by reaction with dialkanolamine and monocarboxylic acid
Inventor: GOERLITZ WOLF-DIETER DIPL CHEM
IPC: C09D163/02
Filed: 1976-01-22
Abstract: A mixt. of stable epoxy resin solns. self-emulsifiable with H2O comprises (a) 5-95 wt. % of a mixt. of epoxy resin derivs. of formulae (I) and (V) and (b) 5-95 wt. % of a mixt. of (I') and (V'). (I) R'-O (D).(E) n(D).R3 E=-CH2.C(R4)OH. CH2.O-;R2 and R4 = H and/or CH3; R3 = -CH2.C(R4)OH. CH2.+NH.R5R6---A-, where R5 and R6 can be H and -CH2. CH2OH, H and -CH2. CHOH.CH3 ro -CH2. CH2OH and -CH2. CHOH. CH3 and A- is a monocarboxylic anion. In these formulae, n = 1.3-13 and the resins have epoxy equivs. of 300-2000 and softening points (Durrans) of 50 degrees-125 degrees C. Components (I') and (V') of (b) both have the general formula CH2OF.CHOF.CH2OF, where F= R3'.O( A .B).CH2C(R4')OHCHiOCH(R1')(R2')CO-. In F, R3' = R1, where R4 = R4' in formula (V') and either R1 or R3 in formula (I').A = (D)(E) n' and B=(E),R2 being the sam in each case or A=(E) or CH2CH(CH3)-O)8-11 and B is absent; R1 = -(CH2)5.CH3; R2'=-(CH2)7-CH=CH.CH2- and n'=0-13. The resin (b) has an epoxy equiv. of 440-4000 and the sum of (a)+(b) = 100%. Used in surface coatings for high duty applications. Epoxy resins have previously been used in powder coatings but, in spite of the undoubted advantages as regards durability, poor flow results in poor surface properties. A high investment cost is involved in the process of powder coating manufacture. The invention avoids these problems by use of an aqueous system which does not involve-costly or inflammable solvents. In an example an epoxy resin reacted with ricinoleic acid triglyceride was used to modify the same untreated resin and a 150; 33 mixt. was reacted with diethanolamine and lactic acid to give a satisfactory H2O-dispersible prod.

Title: Engine air cleaner for combine harvester - uses variable speed blower to eject cyclone extracted solids at duct lower edge
IPC: F01P11/12
Filed: 1976-02-06
Abstract: The engine air cleaning arrangements for agricultural or industrial veicles, esp. combine harvesters, comprises a cyclone-type separator supplied with air for both combustion and cooling from a blower which shares its horizontal driveshaft with the separator. Running under the separator and in communication with its air space is a duct, with its axis at a small angle to the horizontal and tangential to the separator periphery. A blower at the upper end of this duct, with variable speed drive (Pref. electrical) blows air down the duct causing it to entrain the solid contaminants carried towards the periphery of the separator and to eject them through the duct lower end, open to atmosphere.

Title: Roller bearing with axial restraint - has outside race with grooves holding inner race and closing ring
Inventor: NEESE GERHARD
IPC: F16C33/60
Filed: 1976-04-15
Abstract: The cageless solid roller bearing is used for accommodating radial and thrust forces. The outside and inside races carry continuous unsplit roller guide rings. the guide rings prevent inadvert separation of the bearing components in transport or during fitting. These rings prevent axial displacement of the races but do not cause additional friction forces, which are generated e.g. by sliding seals. The inner race has a raised step which matches the groove in the outside race. The other side of bearing is closed by a stepped ring (8) whose circumferential step (9) matches another groove in the outside race. A narrow sealing gap is formed between the components. The raised steps are forced into the outside race by expansion or shrinking of the material, e.g. by heating the outside race (7) and cooling the inner race (6). The circumferential step depth is few thousandths up to few hundredths of a millimetre.

Title: Gas bulb-operated lighter - has bulb ejecting spring stronger than friction locking force on bulb piercing needle
Inventor: MOHR WALTER ING GRAD
IPC: F23Q2/16
Filed: 1976-06-05
Abstract: The lighters is operated by gas from a bulb inserted into the housing. A needle/valve combination pierces the closing cap on the bulb to open the gas supply to the lighter. During the insertion of the bulb (39) a cup-shaped extension (41) of the plug comes to rest against the lower end of spring (42) and when the plug is fully inserted the spring is compressed. The plug is kept in place by a hinged locking lid fitted at the bottom of the lighter. When the plug is spend and the lid opened the spring ejects the plug to such an extent that the end of the plug can be gripped by hand and removed. When the plug is in place it is in frictional connection with the flame adjusting assembly of the valve. This frictional connection is immediately interrupted when the plug is ejected, so that unintentional disturbing of the preset valve adjustment is prevented.

Title: Sports shoe with protruding heel sole - has sharply inclined sole tread running up to lower edge of heel upper
Inventor: DASSLER ADOLF
IPC: A43B5/06
Filed: 1977-02-17
Abstract: Sports shoe is provided with a tread sole (2) of resilient plastics wherein an extension (5) which projects down beyond the lower edge of the heel (30) runs sharply inclined from its rear end towards the lower edge (30) of the upper. At its rear end the extension (5) has half the thickness beneath the rear heel edge (30) and provides improved support comfort for the athlete. The actual shoe base pref. comprises a heel wedge (3) and the tread (2). The latter is extended in its entire thickness over the lower edge of the upper whilst the heel wedge (3) extends over the lower edge (30) but tapers off towards the rear end of the tread (2). Since the heel wedge is normally made from a different material than the tread the combination of materials can control the resilient and damping properties of the sole extension.
