Title: Lubricant blend
Inventor: MORTON RONALD WILLIAM
IPC: C08G59/56
Filed: 1949-03-18
Abstract: A complex ester of general formula R1-OOC-R2-COO-R3-OOC-R4-COO-R5 in which R1 and R5 are aliphatic alcohol or ether alcohol residues, R2 and R4 are the hydrocarbon radicals of aliphatic dicarboxylic acids and R3 is the hydrocarbon or oxygenated hydrocarbon radical of a glycol or polyglycol, all the radicals being saturated and the total number of carbon atoms being between 20 and 100, is blended with a liquid aliphatic diester of a saturated aliphatic dicarboxylic acid to give a lubricating composition.  Preferably the total number of carbon atoms in the complex ester is about 30-60.  The complex esters are preferably prepared by the glycol halfester method described in Specification 666,697 from C4-C24 polyglycols, C1 to C12 alcohols and C6-C20 dicarboxylic acids.  The starting compounds may be relatively straight chain compounds, but 2-ethyl hexanol and iso-octanol are preferred as R1 and R5 to give low pour points.  The blends may also be prepared by the method described in Specification 687,347. Each radical R may be a blend of materials if desired, e.g. polyglycol fractions, mixtures of dibasic acids and OXO alcohol cuts.  The preferred esters are prepared from octyl or nonyl alcohols, adipic or sebacic acids and triethylene or tetraethylene glycols.  The preferred diesters are esters of C1-C12 aliphatic alcohols, particularly branched chain alcohols such as 2-ethyl hexanol, iso-octanol, a nonanol or an OXO alcohol, with a C6-C20 aliphatic dicarboxylic acid, particularly of the polymethylene series such as adipic or sebacic acid.  Suitable esters are di-(2-ethylhexyl)-sebacate, di-iso-octyl sebacate and dinonyl sebacate.  Blends containing up to 70 per cent diester by volume are satisfactory as aviation turbine lubricants, but blends containing a major proportion (60-70 per cent by volume) of the complex ester are preferred. Antioxidants, preferably of the phenolic type such as 2,6-di-tert.-butyl-4-methyl phenol, may be added in amounts up to 1 per cent by weight, preferably 0.1 to 0.5 per cent.  The results are given of tests on blends of (1) a complex ester from 2-ethyl hexanol, sebacic acid and polyglycol 200 with dinonyl sebacate and di-iso-octyl sebacate, (2) a complex ester from nonyl alcohol, sebacic acid and polyglycol 200 with di-octyl, dinonyl, di-capryl, and di 2-ethyl-hexyl sebacates, and (3) a complex ester from 2-ethyl hexanol, sebacic acid and polyglycol 200 with di-nonyl sebacate. Specification 687,348 also is referred to.

Patent GB-1420889-A (GB)
Title: Sound film projector
IPC: G03B31/04
Filed: 1974-02-19
Abstract: 1420889 Sound film projectors K VOCKENHUBER and R HAUSER 19 Feb 1974 [19 Feb 1973] 7621/74 Heading G2E A sound film projector has a motor-driven flywheel which rotates a sound spindle, a roller which can be brought into engagement with the spindle to drive the film strip between them, and a claw feed member for intermittently driving the film past the projection window, the claw feed being detachably coupled to the motor. As shown, the motor 2 drives, through a clutch 8, 9, a main spindle 10 which carries, at its farther end, a three-bladed shutter disc 13 see also Fig. 2 (not shown), and also carries cam means for intermittently driving the claw feed 14. This carries the film past the projection window formed by a lamp 15 and lens 16. The motor also drives, via a pulley 4 and belt 5, a flywheel 6 having a spindle 7. The main spindle 10 carries a pinion 31 which can drive, via an intermediate gear 30, a gear-wheel 29 and hence a control spindle 26. This can be pushed axially by means of a handle 37, so that gear 29 can be brought into or out of engagement with pinion 31. When spindle 26 is drawn to the left (position of Fig. 1), a lever 35 is pivoted to disengage clutch members 8, 9, and hence the motor drive. Spindle 10 is now turned by hand, by means of handle 37 via gears 29 and 30, to bring the first frame of the film scene to which sound is to be added into the optical projection path. The movement of spindle 26 also closes a switch 46 which energizes a solenoid 21. This pivots a lever 19 clockwise, which disengages the roller 17 from spindle 7. When the first film frame is in position, the strip recording from which the sound is to be synchronized is started, and solenoid 21 is de-energized so that lever 19, under the action of a spring 20, is pivoted anti-clockwise to bring roller 17 into engagement with spindle 7, and the film begins to run. The movement of lever 19 also brings clutch member 9 into engagement with clutch member 8, so completing the motor drive to spindle 10, and hence to the claw feed 14. At the same time lever 35 is pivoted to slide spindle 26 to the right, and thus disengage gear 29 from pinion 30. Flywheel 6 has been running at its operating speed even though the film has been stationary, so that the operating synchronization speed is reached with a negligible time lag. The sound can be supplied from a separate tape recorder which can provide a signal to de-energize solenoid 21 and so initiate the synchronizing operation.
