Title: Oxymethylene polymers
Inventor: SMALL PERCY ARTHUR
IPC: C08G2/24
Filed: 1961-12-14
Abstract: The cyclic formal of o-xylylene glycol is prepared by refluxing 35.9 parts of o-xylylene glycol (prepared from the reduction of phthalic anhydride with lithium aluminium hydride) with 7.5 parts of paraform, 0.2 part of p-toluene-sulphonic acid and 176 parts benzene in a Dean and Stark separator until 2.5 parts of water has been removed. Benzene is distilled out and a brown liquid is left from which a white solid crystallized on standing.  This is filtered off and the filtrate fractionally distilled at 0.7 mm. of Hg (b. pt. 97-107 DEG C.) to give a white crystalline mass which on recrystallization from ether gave 13.8 parts of the cyclic formal of melting point 37-38 DEG C.ALSO:A copolymer comprises the product of polymerizing a cyclic oligomer of formaldehyde with 1,5 - dihydro - 2,4 - benzodioxepin or a substituted derivative thereof in which at least one of the aromatically bound hydrogen atoms is replaced by a halogen atom, a nitro group, a nitrile group or an alkoxy group.  The preferred cyclic oligomer is trioxane while the copolymer may contain 90 to 99.5% of oxymethylene units.  The polymerization may take place in bulk or solution, in the presence of an electrophilic catalyst and not more than a very small amount of water; the electrophilic catalyst may be a Lewis acid, e.g. boron trifluoride, alone or as a complex.  The polymerization may take place under conditions of shear, the copolymer may be heated to stabilize, in the presence of a weak acid and may be end-stabilized, e.g. with a carboxylic acid anhydride.  The product may be made into moulded or extruded articles, films or fibres.

Abstract: 972,351. Films; stretching plastic sheets. G. BRUCKNER, [trading as BRUCKNERTROCKNERBAU INHABER G. BRUCKNER]. Dec. 3, 1962 [Dec. 7, 1961], No. 45656/62. Headings B5A and B5B. A heated web of organic plastic material is stretched longitudinally between two groups of rollers rotating at different speeds, transverse shrinkage of the web being prevented by maintaining the marginal parts of the web between the two groups of rollers in contact with idler pressure rollers which are inclined relative to each other so that their axes intersect at a certain distance therefrom in the travelling direction of the web. Preferably, the web is cooled while being held at its desired width, or immediately thereafter. In the apparatus of Figs. 1 and 2, a web 1 is longitudinally stretched between two groups of rollers 3, 4, 5 and 6, 7, 8, and heated by means of the electric radiator 9. Two pressure rollers 10 preferably covered with an elastic material, e.g. rubber, and inclined to the direction of movement of the web, press the edge portions of the web against the arcuate roller 11 and thus prevent lateral shrinkage. Roller 6 is water-cooled. In an alternative apparatus, not shown, each pressure roller 10 is associated with a separate counter-roller, preferably rubber-covered, underneath the web. In the apparatus of Fig. 5, the heater 9 of Figs. 1 and 2 is replaced by two hot air channels 15 and roller 6 is not water-cooled, the film being cooled instead by cold-air channels 16.

Title: Electronic timepieces
IPC: G04C10/00
Filed: 1976-11-03
Abstract: 1529904 Analogue-to-digital conversion DAINI SEIKOSHA KK 3 Nov 1976 [4 Nov 1975] 45721/76 Heading H3H [Also in Division G3] A battery voltage checking circuit in an electric timepiece (see Division G3) includes a voltage/ pulse duration converter circuit 12 (Fig. 2). The battery terminals are connectible to terminals 18, 30. In the absence of a measuring signal, the voltage across a capacitor 39 will be substantially that between terminal 18 and potential divider point A which will be at the potential of terminal 30 since FET 25 is OFF and FET 26 is ON. When a measuring signal pulse is produced upon closure of a switch 19, FET's 31, 34 go OFF and FETs 32, 35 go ON and the capacitor 39 starts to discharge through FET 35. The discharge current will be substantially constant and the potential at a point B rises linearly to the level of terminal 18; when it reaches the threshold of FET 40 the latter goes OFF. The time t between the discharge initiation and the switching over of FET 40, is in inverse proportion to the voltage between 18 and A and the width of a pulse from an inverter 42 (waveform 42a, Fig. 4, not shown) will be proportional thereto. Accordingly the number of clock pulses from a circuit 10 passed by a NOR gate 43 when enabled by the inverter output pulse, is a measure of the voltage between 18 and A and thus of the battery voltage. An alternative voltage/pulse duration converter is illustrated in Fig. 6 (not shown).
