Filed: 1974-08-09
Abstract: 1459010 Insulated conductor PALL CORP 9 Aug 1974 [31 Aug 1973] 35266/74 Heading H1A [Also in Divisions B1 D1 and F2] A copper wire is insulated by spinning thermoplastic filaments and subjecting them to a stream of hot air which draws and breaks them into fibres and projects the fibres on to the copper wire as it is rotated and withdrawn along its longitudinal axis. In the example (9) a 0À006 inch layer of polyethylene fibres is formed, the layer having a 90% voids volume. The layer is rendered coherent by intermingling of the fibres and inter-fibre adhesion as the still hot fibres contact the wire. A plurality of orifices situated at different distances from a mandrel (e.g. the wire) can produce a coating having a density gradient. The fibres may be formed from glass or from specified synthetic organic polymers.

Title: Change-speed gearing
IPC: F16H33/16
Filed: 1935-12-20
Abstract: 467,595. Change - speed gearing. IVERSEN, P. A. SCOTT-. Dec. 20, 1935, No. 35311. [Class 80 (ii)] Change-speed gearing comprising a solid drive and a reduction comprises an inertia element or planetary flywheel 20, Fig. 1, which embodies relatively-movable centrifugally-acting means such as mercury, shot, or oil in one or more arcuate slots 21, Fig. 4, in the flywheel 20. In one form, gears 11, 13 fast on driving and driven shafts 10, 12 are connected by stepped planets 18, 19 supported in a casing 14 the gears being of such relative sizes that a large load causes the casing 14 to bear back against a one-way brake 16, the gearing operating on reduced speed with increased torque. As the load falls off, or the speed increases, the centrifugal means keeps at maximum distance from the axis of the gearing, which thus turns solid on high speed. In a modification there are interengaging planets and an annulus. Specification 421,752 is referred to.

Title: Printing machines
IPC: B41J7/30
Filed: 1972-07-28
Abstract: 1385720 Control of printers BELL PUNCH CO Ltd 13 June 1973 [28 July 1972] 35379/72 Heading G4H In a printer comprising character-carrying type members selectively actuatable for the printing of characters, printing is carried out at a rate which depends on the separation between successively actuated members. As described, the printer is an electric typewriter and the separation is determined as the difference in the distances of successively actuated members from one end of the type basket. Signals I1-I8 representing characters to be printed are input via staticizers 12, 14 to programmed read only memories 18, 20 whose output P1-P8 representing the position of the selected member is passed to BCD decoders 58, 60 to produce solenoid driver signals 02-08, 09-014 and to logic 40-48 to produce an upper/lower case signal 01. Logic 30-38 allows the signal code to be extended to cater, for, e.g. CR and TAB operations. P1-P8 are also fed to circuits 54, 56 and adders 64-68 (in complement form) which are operative to subtract the position of the new character from the position of the preceding character. The resulting difference signal A1-A6 is fed via gates 74, 82 to BCD converters 70, 72 and OR gates (only 84 shown) which provide a logic 0 output on a lead which is connected to a selected junction in a series chain of resistors R1-R6. Instead of this signal, a junction ("85 msec." or "200 msec.") may receive a signal from an XOR gate 52 or a gate 90 indicating a case change or a function respectively. Selecting one of the junctions connects a predetermined number of the resistances into an oscillator circuit 62 &c. to vary the frequency thereof, since it affects the time taken for a capacitor C3 to charge to a voltage V ref  to cause a Schmitt trigger 94 to set a bi-stable 92, the set output from which then enables the drive circuits 58, 60. The other output from 92 (connected to the base of a transistor TR1) goes to logic 0 to cause C3 to discharge for 25 msec., after which 58 and 60 are disabled and 94 resets 92. C3 then begins to charge, taking from 25 msec. to 200 msec. to reach V ref  (for the printing of the next character) according to the junction selected by 70, 72 or gates 52 or 90. A TAB or CR signal causes a TAB or CR switch to inhibit operation of oscillator 62 until the operation has been completed; there is then an additional 200 msec. delay to enable the system to settle down. Provision may be made (Fig. 3, not shown) for the detection of identical alternate characters, when further resistors may be switched in to the oscillator circuit to vary the printing speed accordingly.

Title: Manufacture of aniline derivatives
IPC: C07C209/68
Filed: 1935-12-31
Abstract: Aniline derivatives substituted in the nucleus with an alkyl group of 10--18 carbon atoms are made by heating aniline or a C-methyl- and (or) C-chloro-aniline with a saturated primary aliphatic alcohol of 10--18 carbon atoms in the presence of a halide of zinc or cobalt. Alternatively, an aniline derivative substituted on the nitrogen atom with an alkyl group of 10--18 carbon atoms, and either unsubstituted in the nucleus or substituted with one or more methyl groups and (or) chlorine atoms, is heated with a halide of zinc or cobalt.  In either process the aniline or aniline derivative used as starting material may be wholly or partly replaced by its hydrochloride or hydrobromide; the hydrochloride or hydrobromide of the corresponding N-unsubstituted aniline may also be present in the process wherein a N-substituted aniline is the starting material. Specified alcohols which may be used are decyl, dodecyl, tetradecyl, hexadecyl and octadecyl alcohols, and these may be pure or crude products; thus, use may be made of crude hexadecyl alcohol, obtained by saponifying crude spermaceti, or crude dodecyl and tetradecyl alcohols ("lorol"), obtained by reducing mixed acids from coconut oil and palm oil. Examples are given of the manufacture of (1) p-dodecylaniline from dodecyl alcohol, aniline, aniline hydrochloride, and zinc chloride; (2) p-dodecylaniline from dodecyl alcohol, aniline, aniline hydrochloride and cobalt chloride; (3) p-dodecylaniline from N-dodecylaniline, aniline hydrochloride, and zinc chloride; (4) p-dodecylaniline from N-dodecylaniline, N-dodecylaniline hydrochloride, and zinc chloride; (5) p-dodecylaniline from N-dodecylaniline and zinc bromide; (6) p-dodecylaniline from N-dodecylaniline, aniline hydrochloride and cobalt chloride; (7) 5-dodecyl-2-toluidine from dodecyl alcohol, o-toluidine, o-toluidine hydrochloride and zinc chloride; (8) 3 - dodecyl - 4 - toluidine from dodecyl alcohol, p-toluidine, p-toluidine hydrochloride, and zinc chloride; (9) p-dodecyl-o-chloraniline from dodecyl alcohol, o-chloraniline, o-chloraniline hydrochloride, and zinc chloride; (10) p-decylaniline from decyl alcohol, aniline, aniline hydrochloride and zinc chloride; (11) p-tetradecylaniline from crude tetradecyl alcohol, aniline, aniline hydrochloride, and zinc chloride; (12) p-hexadecylaniline from cetyl alcohol, aniline, aniline hydrochloride and zinc chloride; (13) p-octadecylaniline from crude octadecyl alcohol, aniline and zinc chloride, and (14) a mixture of p-alkylanilines from an alcohol mixture from coconut oil acids, aniline, aniline hydrochloride and zinc chloride; in each example the reaction is effected at about 240 DEG  C.  The acetyl derivatives of p-dodecylaniline, p-decylaniline, p-tetradecylaniline, 3-dodecyl-4-toluidine, and p-hexadecylaniline are mentioned.  The products are useful as intermediates for dyes (cf. Specification 443,776).  N-Dodecylaniline, used in some of the examples, is obtainable by heating dodecyl alcohol with aniline and aniline hydrochloride at 180--200 DEG  C.

Abstract: 785,464. Laminating apparatus; rollers. PITTSBURG PLATE GLASS CO. Dec. 14, 1954, No. 36140/54. Classes 42 (2) and 140. [Also in Group XXX] To seal the edges of an assembly of bent glass sheets and an intermediate sheet of thermoplastic material prior to autoclaving to effect laminating, the assembly is passed through a preliminary pressing apparatus which comprises a roller housing pivotally mounted on, for limited movement, its horizontal axis in a supporting structure, a pair of co-operating resilient nipper rollers mounted horizontally one above the other in said housing, and means for driving the rollers, and force-providing means directly connected to the supporting structure for intermittently turning the housing to one limit of its range to receive the forward edge of said bent assembly without biasing the housing to said limit during the pressing operation. As shown, a frame 4, 5 supported by an antifriction universal suspension from a fixed beam 3 carries a pair of rigidly-connected counter-weighted drums 37 which are connected by universal joints to guides 41 and form a housing within which are mounted on roller bearings surrounding the drum axes an inner assembly comprising opposed carrier members 17 between which are rigidly mounted a pair of rubber-covered pneumatic-tyred mutually deforming rollers 15 backed by rigidly mounted rollers 16, one 16A of which is driven by a variable-speed electric motor. The rollers 15 are inflated by compressed air fed along a line secured to hollow roller trunnions and passing through apertures in the roller core. Synclastically curved glass motor car windscreen assemblies A, typically with frusto-conical quadrant ends, are brought endwise to the press from an oven by a driven roller conveyer B, and when one end is beneath the nip of the rollers 15 a vertical lift C having undriven rollers raises it to engage them. The counterbalancing of the drum is adjusted so that as the rollers feed the windscreen between them the drum is lowered and the inner assembly rotates so that the rollers run along the windscreen which is moved horizontally across the press to the rollers of a second lift C<SP>1</SP>. When the windscreen leaves the nip of the rollers 15 this lift lowers it on to a roller conveyer B<SP>1</SP> which transports it to a second oven and press. The interrelated conveyer movements may be controlled by limit switches, e.g. photo-electric cells, operated by the assembly A. The rotation of the drum inner assembly during the pressing takes up a slack loop in a chain connected to a piston which is operated when the windscreen leaves the rollers 15 to return the assembly to its initial position, the return of the piston reforming the chain loop.
