Title: Improvements in or relating to arc welding
IPC: B23K9/073
Filed: 1963-04-30
Abstract: 1,007,480. Welding by fusion. UNION CARBIDE CORPORATION. April 30, 1963 [May 3, 1962], No. 16896/63. Heading B3R. [Also in Division H2] In order to facilitate the setting up of an arc welding apparatus, the controls for adjusting the voltage and the electrode feed rate are mechanically coupled in such a manner that for any given electrode diameter, the voltage and electrode feed rate may be adjusted by a single control which at all positions provides satisfactory welding conditions. In an arrangement, Fig. 3, for short-circuiting type metal transfer across the arc, the welding voltage is varied step-wise by a slider 14 actuated by a control H coupled by a variable gear 22 to a potentiometer P2 which continuously varies the speed of a feed motor M. A resistance R1 in the potentiometer circuit is preadjusted in dependence on the diameter of the electrode to be used. A small resistance R2 serves to vary the feed rate at the low speed end of the scale. Continuous adjustment of the control H provides the result shown in Fig. 4 in which as the feed rate and consequently the current increase; the voltage increases step-wise at points 29, 30, 31 without the welding parameters departing from between the lines 32, 33 representing the limits between which short-circuiting type transfer occurs. The switch 17 enables the feed ratio to be determined by an independent potentiometer P1 if so desired. In a modification which can be set up for spray or short-circuiting type transfer, a compound slider engages adjustable tappings on the potentiometer P2 so that changes in voltage and feed rate occur stepwise and simultaneously.

Title: Improvements in and relating to Apparatus for Indicating the Ground Speed of Aircraft.
Inventor: BRIZON JEAN
IPC: G01P3/36
Filed: 1919-07-05
Abstract: 129,634. Brizon, J. July 6, 1918, [Convention date]. Speed indicators operating by sighting terrestrial objects. - The ground speed of aircraft is determined by driving a helix 12 from an air propeller 1 through a transmission which can be varied according to altitude. By means of a brake the propeller is retarded until the apparent speeds of ground objects and the helix as viewed in a mirror or on a screen coincide; a speedindicating instrument driven from the propeller thereupon shows the speed. The propeller 1 through spur and bevel gearing rotates a shaft 8 carrying a disk 9 engaged by a friction wheel 13 adjusted radially across the disk according to the altitude by means of a nut and screwed spindle 15 turned by an external knob 18a. The wheel 13 is keyed to the spindle of the helix 12 which is reflected, together with the ground, in an inclined mirror 18. A brake 21 is applied to the propeller shaft until coincidence of travel is observed in the mirror, and a reading is then taken of the speed indicator 11 which is driven from the spindle 8 by gearing 10. In a modification, Fig. 4, an image of the ground is thrown upon a screen 22 by means of a prism 23, and an image of the helix 24 by means of an optical system 25 Adjustment for altitude in this case is effected by varying the magnification of the helix image by shifting the position of the system 25. The angle of drift may be indicated in the first arrangement by noting the angle through which the instrument must be turned to make the apparent paths of the helical tips and the ground objects coincide, and in the second form by graduating the screen 22. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of a kinematograph film to travel in front of the mirror or in place of the screen 22 and thus to record the whole of the observations. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in electric motor controlling apparatus
IPC: B66B1/08
Filed: 1922-06-19
Abstract: 202,786. Waygood-Otis, Ltd., (Otis Elevator Co.). June 19, 1922. Systems for continuous-current motors only; master control systems.-Relates to a system of control for lift motors on multi-voltage supply circuits. According to the invention resistances are connected between pairs of the different supply mains and intermediate points of the resistances are transitionally connected to the motor armature in passing from one supply voltage to the next higher or next lower. The Specification describes a sequence of operations on a five-wire supply when the motor is started and accelerated to full speed in the upward direction. A control handle 49, Fig. 1, when turned to the right energizes the coil of a switch B which disconnects rheostatic braking resistances 5, 6 from the motor armature I and connects the armature across the lowest voltage mains a, b, producing the first or slowest speed. Further turning of the handle 49 effects successive action of electromagnetic switches D, E, F, each action shifting the motorarmature one step up on the mains through a transitional intermediate step due to the connection of the motor armature with an intermediate point. Figs. 2, 4, and 6 show successive, stages of the action of the first switch D in changing the motor lead 68 from its connection with the main b to connection with the next main c via an intermediate resistance tapping 69. Three successive speeds are thus obtained and final full speed is reached by inserting resistance in the shunt field winding of the motor. In order to stop the lift, the operator normally returns the handle 49 to midposition, which reduces the voltage in reverse steps, or in case of emergency cuts off the current entirely by opening a switch N. Automatic stoppin gis also provided for by top and bottom limit switches L and by a speed-governor switch M. In ordinary stopping, the motor is first rlieostat.ically braked by the reinsertion of resistances 5, 6 in parallel with the armature, and is afterwards mechanically braked by the denergization of a brake holding-off coil H. In emergency stopping, a line switch is opened by a magnet A and other rheostatic braking resistances 7, 8 are employed.

Title: Manufacture of styrene compounds
IPC: C07C1/30
Filed: 1947-06-28
Abstract: Styrenes, the benzene ring of which may be substituted for example by alkyl groups or chlorine, are prepared by heating the corresponding chloroethylbenzenes in the liquid phase with more than 0.2 per cent by weight of collidine at a temperature between the lowest at which dehydrochlorination occurs and the boiling-point of the chloroethyl compound.  Specified starting-materials are chloroethyl xylenes, chloroethyl cymene, and chloroethyl mono- or dichlorobenzene.  It is preferred to use between 0.5 and 10 per cent of collidine, which may be added in the form of the collidinium ion as in a salt with an acid such as hydrochloric, phosphoric or acetic.  A batch process may be used but continuous operation is preferred.  If the reaction mixture is heterogeneous, agitation is necessary, for example by blowing an inert gas such as nitrogen through or by refluxing; hydrochloric acid gas is removed simultaneously in these processes.  An inert solvent may be used, e.g. toluene, xylene, ethyl benzene, and is chosen to give the required reflux temperature.  The reactants may be refluxed under reduced pressure, with or without a solvent. The collidine may be pure or a crude mixture of alkylpyridines. The styrene is preferably distilled off through a column as formed.  It is preferred to carry out the reaction in an inert atmosphere.  A polymerization inhibitor, e.g. hydroquinone or pyrogallol may be present.  In the examples: (1) a -chloroethylmonochlorobenzene is heated at 170-180 DEG  C. at 200 mm. pressure with collidine hydrochloride to give chlorostyrene; (2) and (3) vinyl xylene is prepared by refluxing chloroethyl xylene with collidine in toluene or xylene. Specifications 356,107, 387,397, 396,079 and 520,602 are referred to.

The surface of the stationary sub group nearest the object is convex towards the object, and the surface nearest the image is concave towards the image. The image facing surface also has the smallest radius of curvature of any surface in the stationary sub group. Similar constraints apply to the end surfaces of the moveable sub group. Detailed examples are given with reference to Figs. 1 and 2 (not shown). The following constraints preferably apply:- Where F = overall focal length of the objective Fc = focal length of the moveable part of the negative lens group. Rc = radius of curvature of the image side of the moveable part of the negative lens group. Rb = radius of curvature of the image side of the stationary part of the negative lens group. The focal length of the stationary part of the negative lens group is preferably greater than that of the moveable part. Other mathematical desiderata are given. Two mounts Figs.7 and 8 (not shown) are described. In the first, Fig. 7, the moveable part of the negative lens is held in a slidable tube 4. A pin 6 on the tube 4 passes through a longitudinal slot 3a in barrel 3 and engages in internal helical track in sleeve 5. Rotation of the sleeve 5 causes axial movement of the sub group L 22 .
