Patent GB-379760-A (GB)
Title: Process for producing hard soaps
IPC: C11D13/02
Filed: 1931-06-05
Abstract: Hard soaps are made by saponifying fats, fatty oils or fatty acids at a temperature of 125-260 DEG  C. and under a pressure of about 2-6 atmospheres, with the required amount of caustic soda and caustic potash.  Tallow, coco-nut oil, or caproic, caprylic, capric, lauric, myristic, palmitic, or stearic acids or the corresponding glycerides may be used.  Salts such as sodium or potassium chloride, carbonate, borate, sulphate or phosphate, or sodium silicate or borax may be included in the saponification mixture, to lower the solidification temperature of the resulting soap.  Large amounts of these salts, especially sodium carbonate, may be incorporated in the soap together with colloidal clay by using pressures up to 10 atmospheres.  After saponification additional soft fat or oil may be added to form a soap containing 60-70 per cent fatty acids, suitable for milling, or for making soap flakes or powder.  Specifications 378,913 and 378,914 are referred to.

Title: Electric protective devices for the discharge of high potentials
IPC: H01T4/18
Filed: 1925-06-29
Abstract: 239,491. British Thomson-Houston Co., Ltd., (Assignees of Creighton, R. E. F.). Sept. 5, 1924, [Convention date]. Protective arrangements.-A multigap arrester has two or more columns of gaps A, B, C in series arranged side by side and substantially parallel so that electrostatic or electromagnetic induction, or ultra-violet light, from one column may influence the other columns and reduce the equivalent sphere gap of the arrangement. The columns may be enclosed in an insulating tube with walls 2 between the columns which may be transparent to ultra-violet light; porcelain glass and fused quartz are suggested. Each column may be in a separate tube, an insulating or metallic case surrounding all. The arrangement is diagrammatically shown in Fig. 4, the columns A, B, C being supported respectively by a resistance tube 17, an insulating rod. 16, and a metal tube 15 all resting upon a metal plate 18 which is detachably fixed in the bottom of the tube 1 so that renewals may be made without disturbing the arrester mounting. Each column consists of staggered metal plates 5, Fig. 5, secured upon an insulator 4, sections 8, 9 of the plates increasing their capacity to the plates in adjacent columns without increasing their capacity to adjacent plates in the same column. The operation faces 7 have projections and the plates are made thin enough so that metal fused by a discharge may be pushed away through the plate but not so thin as to be affected by normal discharge. The earth lead 21 may be secured to the plate 18 by solder which will be fused by the heat developed in the resistance 17 so that it may drop off and serve as an indicator.

Title: Improvements in the conversion of the acetylene linkage into an ethylene linkage
IPC: C07C5/09
Filed: 1937-06-16
Abstract: Compounds containing acetylenic linkages are converted into compounds containing olefinic linkages by treatment with an aqueous suspension of zinc dust which has been activated by copper and cadmium.  The activated zinc dust may be prepared by treating zinc dust simultaneously or in turn with solutions of copper and p  cadmium salts, or a powdered alloy containing zinc, copper and cadmium, with or without other metals, may be used.  The reaction may be effected in the presence of a solvent, e.g. an alcohol, and/or a dispersing agent, e.g. turkey red oil, and alkylnaphthalenesulphonic acid, a sulphonated higher alcohol, a reaction product of ethylene oxide and a higher alcohol, or a fatty acid tauride.  In the examples: (1) zinc dust is treated in turn with solutions of copper sulphate and cadmium chloride, and an aqueous suspension of the product is shaken with acetylene, which is thus converted into ethylene; (2) an aqueous suspension of zinc dust activated as in example 1 is shaken with vinylacetylene, which is thus converted into butadiene; (3) as in example 2, except that turkey red oil is added to the suspension; (4) an aqueous suspension of zinc dust activated as in example 1 is warmed to 50 DEG  C. with phenylacetylene, which is thus converted into styrene; (5) zinc dust activated as in example 1 is suspended in water with the aid of the sodium salt of oleic acid tauride, and vinylacetylene is passed through the suspension, whereby butadiene is obtained.

Filed: 1968-04-09
Abstract: 1,223,609. Sampling device for gas chromatography; transferring samples for analysis. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. 9 April, 1968 [12 April, 1967], No. 16978/68. Headings B1L and B1X. Samples sealed in mechanically deformable metal vessels, e.g. of gold or aluminium by means of a cold weld are introduced to a gas chromatographic column or other gas analysis apparatus such as a CHN analyser (not shown) coupled at 52 to the injector shown, the vessel being held in recess 75 at the end of rod 74, which is shown at its extreme right hand position under the influence of screw 78 and against the influence of spring 71. As the rod is urged from its left hand position to the right hand position shown, the deformable metal sample holder is pierced through two opposite sides by mandrel 48, and the sample held therein entrained by the current of carrier gas which is continuously flowing through line 92 and channels 96, 100 and 102, and thence through channels 56 to the column. To prevent sample diffusion, a weak current of carrier gas also enters by line 58, and tube 44 is filled with a flow impeding material such as diatomaceous earth. Carrier gas to the column, which enters at 60, is thereby prevented from passing into the injector. Another embodiment is described (see Fig. 7, not shown) in which the entraining carrier gas is introduced to the sample vessel through a channel in the mandrel, which is designed only to pierce one side of the vessel. An automatic carrier gas switching arrangement embodying the injector of the invention is described (see Fig. 6, not shown), as are means for sealing samples in the deformable metal vessels (see Figs. 1-4, not shown).
Patent GB-170058-A (GB)
Abstract: 170,058. Haddan, R., (Pitney-Bowes Export Corporation). June 30, 1920. Postmarking-machines; inking-apparatus.-A machine for printing postage-stamps and recording the number of impressions comprises (1) a detachable meter having a printing-wheel and registering-mechanisms which are automatically locked when the motor is removed from the machine and also after a certain number of impressions have been made, and (2) adjustable inking-apparatus which normally prevents removal of the meter and, when in inoperative position, prevents operation of the printing-wheel. (1) The printing-wheel 38, Fig. 6, is operated from a continually-rotating shaft through a onerevolution clutch 11, Fig. 3, which is normally held inactive by an arm of a three-armed lever 5 supported by a stop-lever 4. The letters pass from a feed-table between rollers 21, 22, and act, through a pivoted trip-finger 1 and a link 3, to withdraw the stop-lever 4, whereupon the lever 5 is caused to release the clutch by a spring 9 acting through a lever 7 and a link 6. The printing-wheel 38 and the registering-mechanisms T, L, Fig. 6, which form the detachable meter, are carried by a casing 34 sliding in guides on the machine frame. The spindle of the printing- wheel has a key 47<a> which is adapted to engage a slotted member 20, attached to the clutch 11, when the meter is in position in the machine. The registers T, L, which are operated from the printing-wheel spindle through gearing and ratchet-mechanism, are separated by a partition and are accessible for resetting through separate doors 35, 36. The register L is arranged to descend to zero, after which it is automatically locked by a pivoted spring-pressed locking-plate having projections which engage notched discs fixed to the, numeral wheels. At the same time, the operation of the printing-wheel is prevented by the closing of an aperture in the meter-casing through which a pin 8, Fig. 3, is normally reciprocated by the lever 7, and a pivoted indicator 61 exhibits the word " dis-charged " at a sightopening 34<c>. When the meter is removed from the machine, the printing-wheel spindle is automatically locked by a latch which engages a notched disc on the spindle, the latch being disengaged by a pin fixed on the machine frame when the meter is replaced. (2) The printing- wheel is inked by a pad or roller 123, Fig. 15, mounted on an arm 124 which can turn on a shaft 23. A catch 125 holds the inking-roller in contact with the printing-wheel. A cam on the shaft 23 renders the printing-wheel clutchmechanism inoperative when the inking-roller is turned away from the printing-wheel. The inking-roller is mounted to slide on the arm 124 and is adjusted so as to contact properly with the printing-wheel by means of a fixed gauge pin 25 or the like. Removal or replacement of the meter is prevented until the inking-roller is out of action by a pin 320 on the meter which is adapted to strike the inking-roller.

Title: Improvements in welding
IPC: B23K11/04
Filed: 1921-06-22
Abstract: 190,734. Hadley, C. A., and A1 Manufacturing Co. June 22, 1921. Welding.-In an electric butt or spot welding machine the rate of displacement of one electrode relatively to the other is automatically controlled independently of the operating pedal lever or like element and is adjustable through the range of travel of the electrodes. In the butt welding machine shown the parts to be welded are clamped in pairs of jaws 1 - - - 4, Fig. 2, the jaws 3, 4 being mounted on a slide 5 connected to one end of a pair of toggle levers 6, 7, which are connected at 8 to an adjustable spindle 10 on which is mounted a spring 11 compressed by a yoke operated by a pedal 13. The slide is also connected by a rod 18 to one of a pair of bell-crank levers 15, which are pivoted at 14 and one of which is connected at its other end to the pistonrod 16 of a dashpot so as to control the motion of the slide. The piston-rod is hollow and is provided with a port 20 so that the oil or other fluid may escape from the lower to the upper side of the piston, but when the port is in the position shown at 22 the passage through the piston-rod is limited by a valve 21 provided on one side with a recess. The oil thus escapes slowly from the lower side of the piston until the position shown in Fig. 5 is reached, when the action of the spring 11 is unrestricted. The upper end of the piston-rod is provided with a graduated disc 23 so that the piston-rod may be rotatably adjusted to vary the restrictive action of the dash-pot. The piston moves in unison with the spindle 27 of a trip switch, which is connected to the second lever 15 and on which is loosely mounted a spring-controlled head 30 carrying a brush 33<1>, which is brought into contact with the contact block 31 when the pedal is flist depressed to bring the parts of the work together. Towards the end of the stroke of the piston and spindle a pivoted gravity catch 28 carried by the spindle, which is notched so as normally to engage the head 30, is tripped by an eccentrically-adjusted stop 29, and so allows the spring 32 to disengage the switch. The parts are returned to their initial position by a spring connected to the pedal, the oil passing through the automatic flap valve 34 in the dash-pot piston. The dash-pot may be replaced by a slow-acting solenoid. The relatively movable parts may consist respectively of an electrode and one or more pieces of work to be welded. A switch such as is described in Specification 167,662 may be used.
