Title: Device for opening ampoules and sealed glass tubes
IPC: B67B7/92
Filed: 1928-03-12
Abstract: 287,172. Merck, W. March 18, 1927, [Convention date]. Cutting glass.-A device for opening ampoules and sealed glass tubes comprises means for cutting the glass and means for striking the part of the tube to be removed. The apparatus comprises a base-plate a having an elongated recess or slot 6 along one edge of which a cutter k is disposed. The holder k<1> of the cutter is free to slide to and from the slot, but is forced towards it by, a spring. A rod e, having a cranked arm e<1>, is journaled in bearings c secured to the base-plate and is surrounded by a coiled spring d. A knob f on the other end of the rod e is provided with pin g which can engage a spring-operated latch h. A bell-crank lever n, pivoted on the underside of the baseplate, has one arm projecting across the slot b while the other arm engages an arm of a lever v, also pivoted on the base-plate. The other arm of the lever v is bent upwards to form the latch h. In use, the knob f is turned to rotate the rod e, against the action of the spring d, until the pin engages the latch h and the cranked arm e<1> takes up the position shown in Fig. 1. The neck B of the sealed glass tube is passed along the slot b and it makes contact with, and is cut by, the cutter k. When it reaches the end of the slot b, that tube presses against and moves the lever n, thus causing the latch h to release the pin g. The spring d then rotates the rod e and the cranked arm e<1> strikes and breaks off the end of the glass tube. The Specification as open to inspection under Sect. 91 (3) (a) also describes a construction in which the cutter and the striker are mounted on two scissor-like members. This subject-matter does not appear in the Specification as accepted but forms the subject of Specification 303,735.

Abstract: 1,221,403. Ethylbenzene. DOW CHEMICAL CO. 12 Feb., 1969 [12 Feb., 1968], No. 7702/69. Heading C5E. Ethylbenzene is prepared by simultaneously contacting ethylene, benzene and an aluminium chloride catalyst complex in a reactor zone maintained at 90-250 C. and a pressure of at least 280 p.s.i.g. for not more than 2 minutes, the molar ratio of benzene to ethylene being at least 1 : 1 and the molar ratio of AlCl 3  in the catalyst complex, to benzene is 0À01 : 1 to 1 : 1. Preferably the product is quickly cooled to below 50 C. and ethylbenzene recovered. The AlCl 3  catalyst complex may be prepared by dissolving AlCl 3  in about an equimolar amount of diethylbenzene while passing HCl over the mixture until all the AlCl 3  has gone into solution. The residual catalyst complex may be separated from the product mixture, adjusted with respect to the AlCl 3  content so that the AlCl 3  : benzene ratio is equal to that of the incoming catalyst complex stream and recycled to said stream.

Abstract: 1275643 Heating yarns ERNEST SCRAGG & SONS Ltd 14 May 1970 [13 Feb 1969] 7747/69 Heading D1F A device 16 removably attachable to a heater, as may be used in a machine for posttreating false-twist crimped yarn, prevents or reduces the deposit of spin finish condensate thereon. Prior to entering the heater, the yarn passes through a zone in which the air is maintained at a temperature sufficiently high to vapourise the finish from the yarn and surface wall(s) defining such zone is/are maintained at a temperature sufficiently low to condense the vapourised finish, the condensate being drained and/or collected. As shown in Fig. 1, yarn 13, carrying perhaps 0.7-0.8% spin finish, passes through a tubular member defining a zone 17 in which air is maintained at a high temperature by convected air from the underlying heater 11 set in a heated block 12 insulated at 15. The vapourised finish condenses on the wall surface 18, which is in poor thermal contact with block 12 and is also cooled by ambient atmosphere acting on an outer grooved surface, and the condensate runs down an internal helical groove into an annular well 16a containing a replaceable absorbent wad 23. In the embodiment of Fig. 3, a condensate collection tray 30, having a drain (not shown), overlies the block 12 and upturned edges 26 of apertures 27 corresponding to the positions of_heaters 11 are covered by devices 16 each comprising a funnel with a castellated base and an upper end protruding through a cover 31.

Title: Improvements in Machines for Welding Metal Bars.
Inventor: FARGUES AMEDEE GEORGES FIRMIN
IPC: B23K11/24
Filed: 1918-05-10
Abstract: 116,278. Fargues, A. G. F., (known as I'argues, H.). May 10, 1917, [Convention date]. Welding.-Consists in an electric welding-machine for metal rods and bars in which the parts to be welded are pressed together by mechanism which comprises a friction drive so that the mechanism is inoperative until the parts are raised to a welding heat. A low-tension transformer placed below the table has its poles 2 projecting through the table in contact with the workholders 3, 4. The holder 3 is fixed in position by an adjusting screw 7, and the holder 4 is pressed towards and withdrawn from the holder 3 by a rotating cam 9 acting on rollers 11, 12. The cam 9 is keyed on a shaft 8 carrying a friction disk 22 pressed against the disk 21 by a nut 23 so that the pressure can be varied to suit the work. The disk 21 is driven by worm gear from a belt-pulley 16 through a clutch 17. In order that the parts may be held' in contact until the weld is complete, the clutch 17 is thrown out of gear by a dog on the disk 22 striking a projection on the rod 24. The dog can be disengaged by a handle 26 on the rod. In a modification, this clutch gear is dispensed with and a device is provided for controlling the welding current automatically. The shaft 8 through gear 29 drives a shaft 28 on which is a cam 30 for making and breaking the welding circuit by means of the switch 31. Preferably the switch is opened just before the weld is completed. By this machine, rods and bars may be welded end to end in line or at an angle, or a T-weld may be made. In the latter case, two transformers may be used, current from one being sent first through the bar to the side of which a weld is to be made, and when the bar is at a welding heat cut off and current from the other transformer sent through the bar, the end of which is to be welded, the previously heated bar being then put in contact with the free pole of the seccnd transformer. Fig. 4 shows holders of copper &c. for making a T-weld, the holder for the bar b b being made in halves 33, 34.

IPC: C01B9/08
Filed: 1926-03-23
Abstract: 249,860. Meyerhofer, A. F. March 24,. 1925, [Convention date]. Hydrochloric and hydrofluosilicic acids; non- metallic fluorides.-Salts of complex hydrofluoric acids are decomposed while being kept in motion in a furnace such as a rotary tube or a reverberatory furnace. The heating may be direct, and in one modification the salt to be decomposed may be injected into a heated chamber, the gas used' for injecting the salt being heated if desired. Gases such as reducing or oxidizing gases, steam,. or acids, or anhydrides or hydrogen compounds may be introduced into the furnace, or may be produced therein. The complex fluoride may be decomposed into its constituent fluorides or into its acid and base. In an example, magnesium silicofluoride may be produced from magnesium chloride and the hydrofiuosilicic acid produced in the furnace, the magnesium silicofluoride being- then further heated with sulphuretted hydrogen which is introduced for the purpose, the ultimate products being magnesium sulphide and hydrochloric acid. The Specification as open to inspection under Sect. 91 (3) (a) states that the whole process may be effected in a long rotary tube furnace, the different reactions being effected at different zones.

A mass, in the form of a bar 17 slotted at 22 for adjustable fixing to the base 18 of the member 5 by means of a wing-nut 23, imparts intermittent and irregular motion to the member 5 by reason of its eccentric location relative to the spindle 9 when the vehicle changes its direction or speed. Pawls 25 pivoted to ribs 7 on the plate 6 engage a crown ratchet 12 on the member 5 to ensure one-way rotation. The member 5 rides on ball-bearings 10, 13 and the pawls 25 may have rubber stops to minimize noise. Display panels 16 may be attached to the member 5 by spring clamping plates 16<1> and may be translucent for internal illumination by a lamp 27, the member 5 being clear of obstructions in the path of the lamp. The member 5 may take the form of any object, creature, or structure.
