Title: Improvements relating to the gasification of heavy hydrocarbons
IPC: C10G9/00
Filed: 1926-03-24
Abstract: 250,220. Mirlesse, L. April 3, 1925, [Convention date]. Oil gas. - Heavy hydrocarbons are gasified during passage through heated perforated discs or circulation through heated passages containing conical bodies arranged in the annular space between a central tubular part through which hot gases are passed and a heated casing. When used for internal-combustion engines the hot exhaust gases pass through a central tube 2 and around an annular space 7 the proportion of gases passing to these two places being controlled by sliding the inlet 4 and outlet 5 towards or awav from the tube 2. The fuel and air enter by a nozzle 6 having ribs 8, the partly atomized mixture flowing between teeth in superimposed rings 10 between which are spaces 11 the mixture passing alternately through narrow and flared passages whereby complete atomization and mixture with the air takes place. A fuel reservoir may be formed on the casing so that the hydrocarbon is preheated. Any source of heat may be employed, including electricity, when the apparatus is used for general purposes. In Fig. 4, discs 13 having perforations 14 are provided, additional air or gas being supplied through pipe 15 and orifices 16. In Fig. 8, frusto-conical members 17 are provided, the additional gas or air being admitted through a branched pipe 18 or pipe 19 leading to a jacket having orifices 20 or the pipes 18, 19 may be used to admit various hydrocarbons which are mixed in the apparatus.

Title: A method and a machine for forming screw threads without cutting off chips
IPC: B21H3/04
Filed: 1955-03-21
Abstract: 778,427. Rolling screw-threads. GROB, E. March 21, 1955 [March 20, 1954], No. 8145/55. Class 83 (4). In a method of rolling screw threads, form rollers b. Fig. 1, are brought into repeated engagement with work a and the relative feed is arranged so that the rollers first engage the work a in the region nearest its centre and roll the surface over overlapping portions d and push the material towards the outer diameter. In one example freely rotatable form rollers b, Fig. 3, are mounted on two opposed rotary heads t and repeatedly engage the work a which is mounted in a chuck q. Relative feed for the work is obtained by mounting the chuck q on a splined shaft p which is rotated through a gear o and is fed axially by a threaded nut s. The rotary heads t are mounted in carriers g which are adjustable angularly in bearings h to suit the helical angle of the thread being rolled. Drive for the heads is provided through cardan shafts m and worm gears l. In another example the form rollers b, Fig. 6, may be mounted on an annular head 12 which is rotated in a race ring 11 by a pinion 14 engaging internal teeth 13 and driven by an electric motor. In this and other examples the workpiece may be supported by a backing roll which is so shaped that it supports the workpiece both in front of and behind the working area. In other examples the forming rollers may be driven through spur gears engaging a fixed gear or annular toothed ring to introduce a sliding motion over the workpiece and provide a smooth wear-resistant surface. In rolling the work a, Fig. 8, one forming roller b<SP>11</SP> may form the outer edges of the thread while the roller b<SP>111</SP> forms the thread to the full depth. In another example the roller b, Fig. 9, has ribs 16-18 which progressively deepen and increase the flank angle of the thread.

Patent GB-922914-A (GB)
Title: Improvements in means for arresting a yarn package
IPC: B65H63/036
Filed: 1961-03-07
Abstract: 922,914. Arresting motion of yarn packages. LEESONA CORPORATION. March 7, 1961 [April 18, 1960], No. 8359/61. Class 120 (2). A machine for winding packages 10 includes an elongated grooved plate 34 against which the package 10 can be pressed to stop its rotary motion if there is a breakage or termination of the yarn supply. The grooves are set at an angle to the longitudinal axis of the plate such that the helix of the twisted fibres is at an angle thereto, preferably 90 degrees, to prevent the strand from untwisting during the braking action against the plate 34. Fig. 8 shows a yarn strand Y<SP>1</SP> contacting a land 60 of the grooved plate 34, the helix of the twisted fibres being at an angle of about 50 degrees to the land 60. When the rotation of the package 10 has ceased it is pressed against a reverse roll 28 that rotates the package in an unwinding direction to allow a suction nozzle 30 to lift the yarn end away from the surface of the package. This yarn end can then be knotted to a fresh supply or the end from which it parted. Specification 704,931 is referred to.
Patent GB-373093-A (GB)
Title: Improvements in or relating to picture scanning and composing devices for televisionapparatus
IPC: H04N3/08
Filed: 1932-03-21
Abstract: 373,093. Television. FERNSEH AKTGES., Goerzallee, Zehlendorf, Germany. March 21, 1932, No. 8377. Convention date, March 27, 1931. [Class 40 (iii).] Relates to television scanning devices of the kind in which the image of a stationary aperture 2, situated in the focal plane of a lens system 3 and illuminated by the fluctuating light source 1 is thrown upon a screen 8 by means of a Weiller mirror-wheel 5 or like system of moving reflectors and a second lens system 6. According to the invention, in order to avoid overlapping or non-contacting of the successive lines forming the image, the ratio of the focal length f of the lens system 3 to the length k of one side of the aperture 2, supposed square, is made equal to Z/4f, where Z is the image point number, i.e. the ratio of the size of the picture image to the size of the image of the aperture 2. Since the size of the aperture 2 cannot readily be made adjustable to the necessary degree of accuracy, the preferred method of carrying out the invention, i.e. to adjust the value of the ratio f/k, is to employ an optical system 3, the focal length of which is capable of variation. This may be achieved by the use of two lens systems 9, 10, the focal length of the combination being varied by altering the distance apart of the two components. In the case of an aperture 2 which is not square, the value to be given to k is that of the side of a square aperture which would give an image of the same size as that given by the non-square aperture. The invention is also applicable to scanning-devices at the transmitter.

Filed: 1937-03-25
Abstract: 469,598. Door &c. fastenings. NEWMAN & SONS, Ltd., W., and SHEAD, H. C. March 25, 1937,No. 8777. [Class 44] A device for automatically withdrawing the bolts of doors consists of a spring pressed plunger 10, housed in a fitting 7 independent of the bolts, which acts through a foot 12 and a projection 13 on the bolt 1 ; when the bolts are shot the plunger 10 is held in the retracted position by two catch levers 15 which are prevented from moving inwards by the armature 26 of an electromagnet 14. When the magnet is energized it attracts armature 26 and the spring 11 forces the plunger 10 downwards together with the foot 12 and block 13 to withdraw the bolt 1. The foot 12 also causes the levers 15 to move inwards against the action of spring 25. To reset the device the bolt 1 is shot by hand and block 13 and foot 12 are raised against the force of spring 11. The hook parts 24 of catch-levers 15 wipe against the surface 28 of foot 12 under the action of spring 25 so that when the foot is raised high enough they hook underneath it. The current having been switched off, the armature 26 falls and holds the levers 15 in the outward position. An adjustment screw 29 limits the fall of the armature. The catch-levers 15 are attached to the housing 9 by pins 19 and 21 and rod 20. The electromagnet 14 and plunger housing 9 are attached to the door 8'by an attachment part 7 which bridges the bolt 1, and form a fitting which is independent of the bolt.
