Title: Ortho-nitrophenol as isoprene polymn inhibitor
IPC: C07C7/20
Filed: 1971-05-26
Abstract: The polymsn. of isoprene is prevented by the addition of 0.01-1 wt.% of o-nitrophenol, depending on the amt of impurities present, the temp etc. Pref. the o-nitrophenol is added as a soln in isoprene to the crude reaction product from the dehydrogenation of isopentane and decomposition of dimethyl-4,4-dioxane-1,3 and the mixture purified conventionally. Prevents blocking of purifn. appts. since any polymsn. leads to soluble low mol.wt. oligomers.

Title: Blow moulding two compartment can - using spreadable fingers to flatten preform before blowing
IPC: B65D1/12
Filed: 1971-10-27
Abstract: A container consisting of a pair of compartments located back to back and connected by a thin strip and having outlet spouts is made by extruding a tube of not thermoplastic material between a pair of blow mould halves. each half is provided with a pair of compartment forming cavities each having a spout forming region, the compartment forming cavities being separated by an upstanding cooled wall between which material is pinched to form the connecting strip.

Filed: 1971-12-14
Abstract: 1358549 Corrugating E W VAN DIJK 14 March 1973 [14 March 1972] 12353/73 Heading B3E A series of undercut corrugations are formed in sheet metal by moving towards each other two clamps on the sheet, while a former moves upwardly between them, so that the sheet is folded around the former to form an undercut corrugation. In the figure, clamps 2a, 2b and 3a, 3b have moved together from stops 6b, 6d to abut stop 5a, while a former 4b has moved upwardly between them to meet a descending counter-die 4a, so as to form a corrugation to the shape of the former. Stops 7b, 7d are then moved to the position shown, and the clamps withdrawn against them, as shown, opening the corrugation enough to allow the former to be withdrawn downwardly. The clamps are then moved towards one another again to reshape the corrugation. Stops 7b, 7d are then withdrawn, and the clamps released and returned to stops 6b, 6d, clamp member 3a rising sufficiently to allow the formed corrugation to pass beneath it as the sheet 1 advances to the right. If the material is sufficiently springy that the former may be pulled out of the corrugation without deforming it, opening and re-closing of the corrugation may be omitted.

Title: Reduction gear drive utilising flexible toothed wheel - provides large reduction ratio with compactness and low weight and positive drive
Inventor: VOLKOV D P
IPC: F16H49/00
Filed: 1975-03-13
Abstract: The drive housing (7) embodies a fixed gear ring (1) with internal teeth. Within this ring is a flexible gear ring (3) in the form of a sleeved thin-walled tube whose length is greater than the thickness of the fixed gear ring. The input shaft (6) is coupled via reduction gears (45, 46) to a hollow shaft (14) carrying three eccentrics (26, 27, 28) with ball bearing mounted rings (38, 39, 40). The rings of the eccentrics press against the sleeve of the flexible gear ring, forming it to an oval shape so that its teeth engage with those of the fixed ring in two regions. Since the flexible ring has fewer teeth than the fixed ring, the former rotates at a speed proportional to the difference. Couplings (8, 9) transmit the rotation to the output flange.
