Title: Width stretching roller for sheet material - has curvature developing in sinus form to compensate unevenness
IPC: D06C/
Filed: 1975-11-28
Granted: 1981-02-10
Abstract: A width holding arrangement for handling sheet material consists of a stretching cylinder formed by a stationary central shaft supporting a flexible mantle or a number of tubular sleeves coupled together. The shaft is carried in pivoting bearings and thrusters act on the shaft ends, applying turning moments in the same or contrary direction round the corresponding bearings. It is thus possible to impart a curvature running in sinus form to the stretching cylinder. The arrangement is esp. applicable to weft straightening in piece goods processing since its sinusoid curvature allows it to deal with irregularities altering constantly.

Granted: 1988-01-28
Abstract: Cement clinker is produced by (a) dry grinding raw cement components to prepare raw meal; (b) mixing the raw meal with solid fuel; (c) pelletising the mixt. with concurrent addn. of calcium chloride CaCl2; (d) drying the pellets in a heated drying zone in a dense layer; (e) roasting the layer of pellets by burning a solid fuel over the surface of the layer and holding the temp. of the resultant gaseous prod. at 1150-1250 deg.C for no longer than half the roasting period and drawing fuel combustion gaseous prods. through the pellet layer and removing exhaust gases; (f) lowering the temp. to 900-1000 deg.C to effect dechlorination, gradually in the direction of the cooling zone; and (g) cooling the cement clinker to ambient temp. The process combines the advantages of improving the clinkering process by lowering the temp. of the final clinkering with the acid of calcoum chlorode, currently only used in rotary kilns, with the advantages of roasting by burning a fuel over a layer of pelletised material on a sinter bed and drawing hot gases through the bed.

Title: Continuous hot strip rolling - by removing scale and lap welding before final hot rolling stage
IPC: B21B/
Filed: 1977-09-30
Granted: 1985-06-18
Abstract: Continuous hot strip rolling process is achieved by, before or during the final hot rolling stage inserting an agent between the overlapping ends of two strips in sequence which will react with the scale to form a low m.pt. cpd., welding the overlapping ends by reduction in the mill, after opt. tacking temporarily with nails, and then passing the continuous strip through the final hot rolling stage. The 'dead' time usually arising out of waiting for the exit of the previous strip before rolling the second is eliminated. The weld between the sheets is sufficiently strong for rolling under strip tension.

Title: Vehicle wheel-drive differential
Inventor: SCHOU CARL E
IPC: F16H48/12
Filed: 1983-04-21
Granted: 1992-07-29
Abstract: The vehicle coupling differential has a conventional housing (10) made of two parts (11,12), one of which carries a flange (16) for a gear wheel (17) driven by a drive pinion to drive the housing (10). A hexagonal drive rod (25) is fitted diametrally across the housing. A pair of coupling rings (30) are inside the housing (10) either side of the drive rod (25), which is loosely fitted in V-shaped cutouts (31) in the coupling rings (30). The axle shafts (20) have spliced ends held in the axle muffs (23) connected by clutch plates (46). When one wheel rotates faster than the other, the coupling rings (30) rotate, so that one is forced from the drive rod (25). This allows it to move inwards freeing the clutch and thus the wheel axle, until the wheel speeds return to being equal.

Patent MX-165406-B (MX)
Inventor: JORGENSEN AUGUST HENRY JR
IPC: C09J109/02
Filed: 1989-12-05
Abstract: Nitrile rubber emulsion latexes containing anionic emulsifying aids such as surfactants are treated with large amounts of cationic polymeric coagulants to form innocuous water insoluble residues. The polymeric coagulants chemically react with the anionic emulsifying aids by forming polymer adducts whereby the adducts are physically maintained in the nitrile rubber. The need for complete or thorough washing steps, which is generally tedious, expensive, and commercially impractical, is thus reduced or eliminated. Moreover, the dried latex particles have been found to have improved properties such as water resistance, adhesion, and the like.

Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate  beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with  alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.

Abstract: There is disclosed a dental prophylaxis device having a pair of spaced tynes disposed on a housing provided with an axial cavity, a stationary support located on the tynes in the vicinity of the base thereof and a circular rotatable disk located on the housing between the bases of the tynes. The circular rotatable disk rotates on a mandrel disposed in the housing cavity through a rotatable drive shaft located in a second housing. A dental flossing thread having a non-elastic loop at one end supported on the circular rotatable disk and an elastic loop on the opposite end supported on the stationary support spans the space between the ends of tynes and reciprocates therebetween when the disk is rotated. The process comprises contacting dentition surfaces with the dental flossing thread described and reciprocating the thread over the dentition surfaces and across the space between the stationary tynes while expanding and contracting the elastic loop in response to the tensile force on the thread and absorbing the tensile force imparted thereto when it encounters resistance and while imparting reciprocating movement to the dental flossing thread through the rotating motion of the disk.
