[Class 44.] The rubber button a of a stocking suspender grip is secured to its baseplate by a shank formed by bending narrow metal strips. Figs. 1 and 4 show arms e integral with a circular baseplate b which are bent to provide an upstanding shank and passed through the suspender tape f and through the button. The button is secured by bending the outer ends of the shank arms to lie in a recess in the button. The arms may be close together, as shown, or spaced apart, and may be passed through separate apertures in the button. The baseplate may be of any suitable shape, and may be housed in a pocket in the tape or may have slots for attachment to the tape in known manner. The button may be made removable by bending the outer ends of the shank arms towards one another, or folding one end over the other, Fig. 6, to provide a curved resilient head over which the button can pass. The arms may be formed by stamping tongues out of the baseplate, and may be provided with strengthening ribs. Instead of being integral with the baseplate, the arms e may be formed from a separate strip and a separate base plate c with inturned edge, Fig. 13, secured thereto. Alternatively, the strip may be bent to U-form and the limbs passed through apertures in the baseplate, Fig. 15.

Title: Process for the preparation of a pure hormone from the anterior lobe of the hypophysis
IPC: A61K38/24
Filed: 1929-06-18
Abstract: 313,924. Schering-Kahlbaum Akt.- Ges. June 19, 1928, [Convention date]. Medicines for internal use.-The hormone of the anterior lobe of the hypophysis, which is found also in the blood, urine, fµces, male and female sexual glands, and placenta, is prepared by treating an aqueous preparation of these organs or liquids with compounds of the alkaline earths or of the heavy metals to precipitate salts and ballast materials, and then separating the hormone in the usual manner by adding an organic solvent to the residual aqueous solution. According to an example urine is concentrated, acidified with acetic acid, filtered, treated by addition of concentrated barium chloride solution, to precipitate impurities, and the filtrate treated with sodium sulphate to remove excess of barium, again filtered, and treated with three times its volume of methyl alcohol to precipitate the hormone. The hormone may be further purified by repeated solution in water and precipitation with alcohol. In further examples-(1) concentrated urine is treated with lead acetate, excess of which is removed by means of sulphuretted hydrogen; (2) finely divided placenta suspended in water is treated with calcium hydroxide and then with carbon dioxide to precipitate calcium carbonate; and (3) anterior lobes of hypophysis are finely divided in a colloid mill and suspended in acidified water, the mass filtered, and the filtrate treated with barium chloride solution. In each of these further examples the hormone is finally separated from the solution in the same manneras in the first example.

Filed: 1926-07-28
Abstract: 256,246. Soc. des Etablissements Singr³n, (Assignees of Veber, G.). July 29, 1925, [Convention date]. Variable - speed gearing comprises epicyclic trains compounded, or a single train in which elements are selectively driven through gear trains of different value from a single driving cone 14, so that a shaft 29 may be .driven at any integral ratio from, say, 1 to 999, where there are two epicyclic trains, as in the arrangement shown. There are three parallel counter-shafts 18, 19, 20 carrying sliding trains 15, 16, 17, respectively, which by means of swinging arms, can be set by hand into mesh with selected steps of the cone 14, which may be driven through a train 21 to get the decimal ratios correct. The shaft 20 drives one side gear 28 of the first train, which is loose on the shaft 29. The shaft 19 drives the loose carrier 12 of the planets of this train. The other loose side gear 7 is thus driven differentially, and drives one side gear 9 of the second train. The shaft 18 drives the carrier 13 of the planets of the second train, the other side gear 23 of which is ultimately driven, and is fast on the shaft 29. As applied to a gear-cutting machine, the shaft 29 drives a shaft 25 at an accurate fractional speed, that speed being readily adjusted by moving the trains 16, 17, 18.

Title: Improvements relating to the manufacture of viscose
IPC: D01F2/08
Filed: 1958-06-13
Abstract: <PICT:0849417/IV(a)/1> <PICT:0849417/IV(a)/2> <PICT:0849417/IV(a)/3> In a process for the production of viscose spinning solutions in a continuous working operation, alkali cellulose is continuously prepared by passing cellulose webs through a hot caustic soda solution, and measured quantities of the alkali cellulose in small loose crumbly and initially ripened condition are rapidly mixed together with the necessary measured quantity of carbon bisulphide and xanthated while mixing, the still loose and crumbly cellulose xanthate being supplied in small measured quantities to an associated quantity of caustic soda solution, the suspension containing the xanthate being homogenised and the viscose solution being advanced to a final ripening stage.  Apparatus suitable for carrying out the above process comprises a dipping trough containing the hot caustic soda solution, means for advancing cellulose webs through the trough thereby to produce alkali cellulose, means for shredding the alkali cellulose, a xanthation device in which measured quantities of the shredded and initially ripened alkali cellulose are rapidly mixed with a measured quantity of carbon bisulphide and xanthated to produce cellulose xanthate, means for suspending measured quantities of the cellulose xanthate in caustic soda solution, means for homogenising the suspension to produce a viscose solution and means for advancing the viscose to a final ripening stage.  As shown, cellulose webs 3 may be advanced by rollers 4 into the upper part 5 of a caustic soda dipping trough.  Lightly touching rollers 9 may compress webs 3 as they pass from upper to lower parts 5, 6 of the dipping trough.  The webs 3 may be subjected to strong pressure by rollers 11 before passing to mixing and crushing worm 15, which shreds webs 3.  Thence the shredded alkali cellulose is advanced via an initial ripening device (not shown) to a xanthation device, e.g. shown in Fig. 2.  The initially ripened shreds of alkali cellulose may be weighed out by the measuring balance, fall through a shaft 16 into a compartment of a bucket-wheel 17, which is rotated in housing 18.  The compartment containing a known quantity of alkali cellulose may be subsequently evacuated via pipe 19, the latter also being used to admit a measured quantity of carbon disulphide to the compartment. On reaching position IV, the sulphidised shreds may drop through a gas tight shaft 20 into mixer 21, and thence are discharged to a controlled feed weighing device (not shown) before passing to the homogenising means.  The latter may comprise the apparatus shown in Fig. 3, i.e. vessel 24, having a cover 25, p  filling sheet 26, spray pipe 27, stirrer 28 and ring valve 29. Examples are given.

Title: Improvements in fluid pressure operated electric switches particularly thermal switches
IPC: H01H35/26
Filed: 1934-06-28
Abstract: 440,362. Thermal switches. WING- FIELD, B. R., Brooklyn, The Green, and DRAYTON REGULATOR & INSTRUMENT CO., Ltd., both in West Drayton, Middlesex. June 28, 1934, No. 19090. [Class 38 (v)] A switch mechanism operated by fluid pressure comprises a fluid pressure operating mechanism acting on a unitary snap action switch which can be operated manually and which has a thermal overload release. The switch unit comprises an insulating block 1 in which is slidable an operating rod 2 urged upwards by a spring 11. Pivoted at 4 to the rod 2 is a curved lever 3 connected at its free end by a spring 7 to a contact lever 6 pivoted on brackets 5. The lever 3 has a downturned lug which rests on an insulating part 9 at the end of a U-shaped bimetallic strip 10. A spring 8 biasses the end of lever 3 in a downward direction. In the position shown, the contact arm 6 engages a fixed contact 16, but if the rod 2 is pulled up, the lever 3 pivots about the lug resting on the part 9 and the end of spring 7 passes across the pivot of contact arm 6 causing a quick break. On depressing the button, a quick make results. On the occurrence of an overload the bimetallic strip 10 moves to the right and the lever 3 is pulled down by the spring 8 to break the circuit. An extension 3a of the lever 3 pushes aside an L-shaped spring catch 14 to release the rod 2 which rises duc to spring 11 thus allowing the mechanism to be reset when the strip 10 has cooled. The switch is also adapted to be operated by a bellows 27 sensitive to fluid pressure which may be generated thermally. The bellows acts on a lever 25 pivoted at 34 and connected by a tension spring 24 to a lever 22 pivoted at 35. On a reduction of pressure the bellows collapses and an adjustable spring 31 moves lever 25 to carry the spring 24 across the pivot 35. Lever 22 then snaps downwards and an insulating part 21 engages an extension 17 of the switch lever 6 to give a quick break. An increase of pressure causes the lever 22 to snap upwards and the switch is closed by spring 7. A modified form of the switch unit is described in which the tension springs are exchanged for compression springs.

Abstract: 312,525. Hancock, L. J. July 3, 1928. Shearing. - A portable metalshearing machine having a movable blade operated by fluid pressure comprises a U-shaped frame 1 of H-section carrying a fixed blade 9 and a movable blade 10. The latter is attached to a fluid-pressure cylinder 2 whose piston-rod 3 is shouldered and secured to the frame. Two side strips 6 on the cylinder slide in guides 7 on arms 8 of the frame and a rubber buffer 27 cushions the return stroke. Fluid is admitted to opposite sides of the piston 4 by two passages in the piston-rod connected to a valve box 11 whose valve stems 18 are arranged in two pairs, each operated by a pivoted plate 19. Two spring triggers 14 are provided, the action being such that on depressing one trigger a plate 19 is raised to admit fluid in part of the piston and connect the space behind the piston to exhaust, while on depressing the other trigger the supply and exhaust are reversed. When the cylinder reaches the forward limit of its cutting stroke the lower part thereof engages two stops 20, whereof one draws forwards a spring-controlled rod 15 and causes a ramp 22 to raise one of the plates 19 through a rod 23 and admit fluid to the rear end of the cylinder, while the other acts through a second rod on a lever 24 to which withdraws a sleeve 25 from under the other plate 19 and allows it to fall, even though the operator continues to depress the corresponding trigger 14, and thus cuts off the supply of fluid to the front of the cylinder. This stop motion prevents the cylinder from jarring against the opposite limb of the frame when the cut has been completed. A handle 28 is provided on the frame.
