Title: Automatically variable gear device
IPC: F16H33/06
Filed: 1935-07-16
Abstract: 453,013. Variable-speed gearing. FONTANA, C., 13, Via Podgora, La Spazia, Genoa, Italy. July 16, 1935, No. 20285. Convention date, July 16, 1934. [Class 80 (ii)] An automatically - variable variable - speed transmission device suitable for a lift comprises a driving-shaft 2 carrying a crank 3, Figs. 1 and 2, which turns round inside a slot member 6, Fig. 3, which is carried round solid with the crank if the load is light enough, or is idly reciprocated if the load is too great to be lifted, or is both reciprocated idly and turned with the load at a speed proportioned to a substantial load. Between the crank 3 and the member 6 is a ball-bearing ring 4, Fig. 2. A casing 17 fast on a load shaft 18 is driven, and inside this on ball bearings 20 is a drum 19, Figs. 5 and 6, which carries rigidly a second crank-pin 34. The drum 19 has oppositelyextending fingers 24, 23 which form abutments for springs 15, 16, Fig. 2. The slot member 6 has a finger 13 which projects along with the finger 24 between the inturned ends 27, 28, Fig. 1, of the spring 15. The slot member 6, Fig. 4, has a longer finger 14 projecting the other way through an arcuate window 29, Fig. 6, in the drum 19 which together with the arm 23 comes between the inturned ends 25, 26, Fig. 1, of the spring 16. The slot member 6, Figs. 3 and 4, has two symmetrical pins 8 which project through windows 30, 31, Fig. 6, in the drum 19 and carry antifriction bowls 10, Fig. 2, which engage a slot 11, Fig. 7, in a second slotted member 12. The member 12 is, as shown in Fig. 8, rigid with a toothed sector 38 which engages an internally-toothed sector 44, Fig. 1, on a flange 43, Fig. 2, rigid with the driven casing 17. The boss 37 of the sector 38 has a circular opening 36 which rides on a ball bearing 35, on the crank 34. When the device is operative, the rotary motion of the driving crank 3 is resolved into an idle reciprocation of the slot member 6 along the other slot 11 and into a torque which tilts the member 6 so that the fingers 13, 14 separate from the fingers 24, 23, as shown in Fig. 18, so stressing the springs 15, 16 while at the same time the member 12 rocks relatively as the sector 38 rolls inside the sector 44 to a position of rest at the end of the rocking while transmitting to the sector 44 and drum 17 a torque varying with the extent of rocking of the sector 38 and the stressing of the springs.

Title: Improvements relating to the production of rayon yarn
IPC: D01D10/04
Filed: 1946-07-08
Abstract: Viscose filaments issuing from the coagulating bath in the continuous process are passed as yarn round at least one pair of truly cylindrical <PICT:0614116/IV(a)/1> <PICT:0614116/IV(a)/2> rollers set at an angle one to the other, at least one of the rollers being provided with a downwards step at the end to which the yarn is delivered so that in a single transfer between rollers the yarn is stretched from about 10 to about 75 per cent of its length as it passes from the reduced diameter of one roller to the normal diameter of the other.  In some cases it may be desirable to provide both rollers a and b, Fig. 1, with a step c at the receiving end so that the reduced diameter portions can more effectively resist the pull of the normal larger diameter portions.  Yarn guides e and f may be provided to assist the yarn d in its passage.  The roller or rollers may be provided with a plurality of steps g, h, i, Fig. 2, only one of which is in use at any particular time, so that the amount of stretch desired can be imparted without change of rollers.  The higher the yarn speed, the lower the degree of stretch which can be advantageously imparted to it.  After stretching the yarn may be subjected to washing, drying, twisting and other treatments.

Patent GB-208737-A (GB)
Abstract: 208,737. Barr, J. M. M. June 28, 1922. Multiplying-apparatus; counting-apparatus with variable-step movement.-Each of the counting mechanism has its own self-contained storage receptacles, through which are circulated balls representing the integers of seected partial products. In the arrangement shown, the right-hand limb of the tube contains a sufficiency of balls to represent the greatest partial product that may be required for delivery to the counter within the limits of the machine. These balls b are normally held up 'by a rod g, but this is withdrawn to release the balls when the selected rod h is made to project into the tube. The factors are represented by inclined rate strips k and axiallyrotatable stem'rods i, and they are arranged to intersect one another according to a predetermined plan whereby, when they are selectively and suitably operated, the rod h corresponding to the partial product required is moved to select the correct number of balls for delivery to the counter. The projecting arm lon, say, the third item rod cannot move the rod h, corresponding to the twelfth ball. into the tube until the fourth rate strip k is first pulled down to position its distance piece m and make an operative connection between the members m<1>, m, l. The same number of balls is also released by first pulling down the third rate strip k, when its distance piece m is behind the stop m' on the twelfth rod for the operation of this rod by subsequent axial movement of the fourth item rod. In a similar manner, balls representing the required partial product are released by the selective operation of other factor members i, k, which may be operated mechanically, electromagnetically, or otherwise. The machine is provided with keyboard mechanism having item and rate keys. The balls are fed through the counter a by a rotary disc d and a spring-pressed lever with arms e, f, as shown. The transfer-balls of each unit are housed in a tube at the side of the primary tube, the counter being common to these tubes. This auxiliary tube is furnished with a ball-release comprising two stops or shelves arranged the width of one ball apart and so that they are actuated by an electromagnet relay energized by the closing of a circuit when the counter of next lower denomination passes from 9 to 0; one ball will then be dropped into the transfer tube. The transfer-balls are not released until the end of the integer count and until a special " finish " key is pressed,'or on the return movement of the last key to be operated.

Filed: 1946-07-13
Abstract: D 20,21 - 3 : 17 - Dihydroxy - 11 - ketopregnene and its 17-acyl derivatives (preferably those containing the radicals of aliphatic carboxylic acids having 6 carbon atoms or less) are manufactured by treating 3 : 17-dihydroxy-11-keto-pregnine-20 or a 3-acyl derivative thereof with hydrogen at room temperature and under atmospheric pressure in the presence of a hydrogenation catalyst of relatively low activity, e.g. nickel, cobalt, platinum or preferably palladium, advantageously in a solvent such as a lower aliphatic alcohol.  When the compound hydrogenated is the 3 : 17-dihydroxy compound, the product may subsequently be acylated in the 3-hydroxy group, e.g. by heating with an acid anhydride in the presence of a solvent.  In examples: (1) 3(a ) : 17(a ) - dihydroxy - 11 - ketopregnine - 20 is shaken with hydrogen in absolute alcohol in the presence of a palladium-barium carbonate catalyst and the product is warmed with acetic anhydride and pyridine; (2) 3(a )-acetoxy-11-keto - 17(a ) - hydroxypregnine - 20 is similarly hydrogenated.  The starting materials may be replaced by the corresponding compounds in which the 3-substituent has the cis configuration, and that of (2) by the corresponding propionic, butyric, valeric, caproic, capric, benzoic, toluic or phenylacetic ester.  Specification 630,432 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use in the hydrogenation of superatmospheric pressure and temperatures other than room temperature.

Title: Process of manufacturing vacuum walled containers
IPC: C03B23/13
Filed: 1921-08-09
Abstract: 185,930. Thompson, W. P., (Vacuum Glass Machine Co.). Aug. 9, 1921. Forming vacuum flasks.-A process for making vacuum bottles consists in exhausting the air from the space between two glass vessels while their necks are in a plastic condition, and then bringing the vessels together so that the necks adhere and seal the evacuated space. The mechanism is described as an attachment to a standard forming machine in which the parison and the blow moulds are carried on separate rotatable tables which are geared together. Two sets of parison moulds are used arranged alternately on the machine table to form the parisons for the inner vessel I, Fig. 7, and the outer vessel 0, respectively, of the vacuum jar. The second table, 11, Fig. 3, similarly carries two sets of blow moulds. The hollow central column of the table 11 carries three cylinders 18, 19, 20, of which the cylinders 19, 20 are in line with one another and their pistons are connected by a rod 23. The piston-rod 25 of the cylinder 18 carries at its lower end a disc 26 and spring-controlled pivoted fingers 28 which are adapted to grip the ring of the inner vessel I. A suctionhead 30 surrounds the lower end of the rod and is formed so as to fit tightly over the tapered exterior of the blow-moulds 16, in which the outer vessels are formed. In use the inner and outer vessels are formed on the machine in the usual manner. The rotation of the table 11 brings the blow moulds beneath the cylinder 18, and when a mould carrying an inner vessel I arrives in position, the rod 25 descends, the grippers 27 engage the ring of the vessel I, and the rod 25 is then raised, carrying with it the vessel I. The next movement of the table brings a blow-mould 16 with an outer vessel 0 beneath the cylinder 30. Air is admitted to the cylinder 30 so that the rod 25 descends a sufficient distance to seat the suction head 30 firmly on the mould 16. Air is then admitted to the cylinder 19 to move its piston 21, and consequently the piston 22 of the cvlinder 20, downwards, thus exhausting air from the head 30 and the space between the walls of the vessels I, O. The rod 25 is then moved downwards through a further distance so that the rings of the vessels I, 0 which are still hot, are pressed together and become sealed. Air is then admitted to the head 30 and the rod 25 is raised to disengage the fingers 28. Finally, the finished vessel is removed from the mould.
