Title: Turret assembly for a machine tool
IPC: B23Q1/54
Filed: 1975-01-07
Abstract: 1490749 Indexing; turrets INDEX-WERKE KG HAHN & TESSKY 7 Jan 1975 [10 Jan 1974] 625/75 Headings B3B and B3T A rotatable tool carrier, e.g. an indexable turret 10 of a lathe, comprises a shaft 56 driven by a hydraulic motor 58 to rotate the turret 10, and control apparatus for slowing down a fast rotary movement to a slow one before the turret is stopped at the required indexed position, said control apparatus including a cam 96 rotatably driven by the shaft 56, a control member, e.g. a valve spool 92 and contact roller 94, engageable with said cam 96, and actuating means, e.g. a magnet M3 and lever 104, for controlling the control member 92, 94 so that during rotation of the turret 10 the control member is initially out of contact with the cam 96 and permits the fast rotary drive of the turret 10, and arranged to bring the control member into contact with the cam prior to the turret reaching its desired indexed position so as to restrict hydraulic flow to the motor 58 to slow down the turret rotation and then to finally stop the turret rotation. The turret 10 rotates therewith a cam shaft 110 carrying cams 108 engageable with switches 53-56 to provide control signals which are used to determine the direction of rotation of the turret to arrive at the desired index position by the shortest distance. The turret is movable axially to disengage annular arrays of teeth 52, 54 by hydraulic means 34, 36, 46, 48. A safety switch S1 prevents rotation of the turret 10 until it has moved axially to disengage teeth 52, 54. The turret is rotated by a pinion 60 on the shaft 56 engaging an internal ring gear 62. The pinion 60 rotates a whole number integer of revolutions for each angular index movement. The turret includes at each station a fixed tool 20 and a rotary shaft 22 for a rotary tool 26. A shaft 70 is coupled with the shaft 22 at one index position for each station of the turret. The lathe is controlled by a programme which operates through the various switches S1-S8 to control the rotation, speed, and direction of rotation of the turret.

[Class 87 (ii).] A press for moulding artificial resins comprises a ram 6 driven by a crank and connecting rod 15 through a toggle which is straightened when the press is closed, the toggle having a relatively short link 14 pivoted on a fixed support 13 and a relatively long link 11 pivoted to a lever 10 operating the ram 6, the said toggle being so arranged that it is approximately at right angles to the connecting rod 15 when pulled into the straightened position thereby, the connecting rod 15 being comparatively short and never more than slightly longer than the crank throw, and the link 14 being not greater than the throw of the crank. The connecting rod 15 is pivoted on a crank pin 16 between two gear wheels 18 which are driven from a reversible electric motor 20. In the construction shown in Fig. 1, the rod 15 is slightly longer than the double crank radius and the pivot 13 is outside the vertical projection of the crank circle. The crank is reciprocated through an arc smaller than a semi-circle. As shown in Fig. 4, the crank 22 rotates continuously and the crank rod 15 is not greater than the double crank radius. In this construction the time of descent of the press ram is greater than its time of ascent. In both cases the speed of the ram decreases as it descends and in addition a slip clutch may be interposed in the gearing 21 which holds the ram under maximum pressure. A planet transmission gearing may also be employed in conjunction therewith. Specification 281,945, [Class 87 (ii)], is referred to.

Title: Method of preparing fatty acid partial esters of a mixture of glucosides of sugars
IPC: C07H15/04
Filed: 1958-01-08
Abstract: Surface-active fatty acid partial esters of a mixture of glycosides of sugar are prepared by esterifying with one or more fatty acids having at least 5 carbon atoms, or the chloride, anhydride or alkyl ester thereof, glycosides of a mixture of aldose sugars obtained by the mineral acid hydrolysis of cellulosic material containing hemicellulose, cellulose and lignin.  The mixture of aldose sugars obtained from gardwoods or softwoods comprises galactose, glucose, mannose, arabinose, xylose and polymers thereof in proportions which depend upon the stage of hydrolysis.  Suitable fatty acid esters are the methyl esters of stearic, palmitic or linoleic acid.  Oleic acid chloride is also specified.  Diesters produced can be reacted with excess of unesterified glycoside to produce the mono-esters, preferably in solvents such as dimethylformamide or dimethyl sulphoxide. The ester products may be reacted with 3 to 40 mols. of ethylene oxide in the presence of caustic soda or sodium methylate to produce detergents, emulsifiers or deemulsifiers depending on the amount of oxaethylation.  The products may be sulphated to increase the foam forming effect.

Abstract: A fabric is bias cut into a continuous strip of fabric. The individual fibers in the continuous strip (12) are impregnated with an elastomeric polymeric material effective to increase the flex and wear-life of the fabric when used as a cover fabric for V belts.
