Filed: 1949-09-29
Abstract: 632,982. Frictional igniters combined with other articles. EDENBURG, J. Sept. 29, 1949, No. 25035. Convention date, April 24, 1939. [Class 75(iii)] [Also in Group XV (Appx)] In a frictional lighter with the friction wheel actuated from a pivoted wick-cap carrier 5, the latter is operated by endwise movement of a member 10 hinged to the carrier 5 and slidable longitudinally on the exterior of the lighter body 1. Such an operating arrangement is applied to a lighter having a small size barrel reservoir 1 similar to a fountain pen, with small size fountain pen and propelling pencil units 22, 23 assembled therewith by short adaptor sleeves 20, 27.

Title: Improvement in rock drills
IPC: E21B21/01
Filed: 1924-10-21
Abstract: 244,224. Marks, E. C. R., (Ingersoll-Rand Co.). Oct. 21, 1924. Percussive tools. - The drill shank D of a rock drill, particularly a stoping drill, the socket J in which it is fitted, and the anvil block C are arranged to move together under the blows of the piston. The inner end Y of the socket fits tightly over the reduced end of the anvil block C, which construction also reduces the leakage of water from the clearing passage U. Water which does so leak into the space Z is removed by means of a passage d, which may act as a drain or as a conduit supplied with pressure air by means of which the water is blown out past the flutes H on the socket. In the latter case the air pressure in the space Z assists in holding the socket J against the anvil block. Where the bore is drilled dry, oil may be conveyed by the air to lubricate the flutes. A cap f is provided to prevent water from running back into the drill head. Rotation of the drill is afforded by an outside handle (not shown).

Title: Improvements in engine stop-gear for motor vehicles
IPC: F02M1/00
Filed: 1930-08-22
Abstract: 360,529. Controlling motor vehicles. MALLINSON, F., 36, Langroyd Road, Colne, Lancashire. Aug. 22, 1930, Nos. 25085/30 and 2477/31. [Class 79 (v).] In the event of motor vehicles or aircraft being involved in a collision, crash, sudden stoppage or overturning, the fuel supply is cut off and the ignition cut out by means released by the displacement of a weight or weighted member, or, in the event of a back-fire, by the melting of a fusible member which normally maintains the parts in the working position. The fuel control valve A is in the form of a slide with an aperture a<1>, and is normally held open against the action of a spring B by a link D of fusible metal, a roller d on which engages an upturned part f of a frame F. When a collision &c. occurs, a weight C which rests normally in a cup c is displaced and lifts the roller d off the part f thus releasing the valve A which is then closed. At the same time the end a2 of the valve makes contact with a part E, and earths the magneto or coil and cuts out the ignition. Should the fuel become ignited through a backfire occurring the link D is fused and the valve released as before.

Abstract: 1534909 Producing selective excitation by means of electromagnetic radiation MASSACHUSETTS INSTITUTE OF TECHNOLOGY 18 June 1976 [23 June 1975] 25314/76 Heading G6P High-lying excited states of atoms or molecules are selectively populated by irradiation successively with first and second pulsed radiations having the same handedness of circular polarization; coherent frequency components of the first radiation have frequencies corresponding to the energy difference between a lower energy level and the frequency split levels of an intermediate energy level; coherent frequency components of the second radiation have frequencies corresponding to the energy difference between the split levels of the intermediate level and an upper energy level; the duration of the pulses of both radiations is less than 2#/##, where ## is the frequency difference of the split levels. The radiations may emanate from a single laser or, preferably, from separate lasers 1, 2. A variable delay element 4 ensures that the second radiation pulse irradiates the atoms or molecules in the chamber 15 after arrival of the first radiation pulse. An electric field applied across plates 21, 22 ionizes the excited atoms or molecules and effects their separation from non-excited ones.  Although other applications are envisaged, separation of isotopes (sodium and uranium, in particular) is particularly described. The theory and mechanics are described in detail.

Abstract: Temporarily fat gypsum plaster, which may be obtained by crushing gypsum rock containing insoluble impurities such as dolomitic limestone, marl and anhydrite and calcining it by indirect heating at atmospheric pressure for 1 to 3 hours to a final temperature of 270 DEG  to 350 DEG F., is mixed with water below its boiling-point to form a slurry and the slurry is classified, preferably before any hydration, either in the form of the slurry itself or in the dry form obtained by drying the slurry without particle-aggregate formation, according to particle size into at least two fractions, the finer consisting of a purer CaSO4 product, the coarser preferably containing all the impurities. The calcined gypsum may be classified into a fine pure fraction and a coarse fraction bearing impurities, the latter only being treated to form a slurry.  The fine pure fraction from the said initial classification may be mixed with the classified slurry to thicken it.  A keratin retarder may be incorporated in the slurry while maintaining the alkali content in the water at less than 1%.

The speed of a D.C. motor is synchronized with the frequency of an A.C. supply, by means of a synchronous switch driven by the motor to select positive or negative halves of each cycle of the supply frequency to energize a regulating field. The control may be applied to amplidyne motor, or a motor with an amplidyne exciter, Figs. 1-3 (not shown), or a conventional D.C. motor, Fig. 11. As shown, the shunt field 95 is adjusted by resistor 96 to run the motor about synchronous speed. The rotary switch 100, which has a 90 degree insulating portion (shown shaded) energizes the regulating field 97 from the A.C. supply. At synchronous speed equal positive and negative halves of the A.C. cycle are fed to the regulating field, Fig. 7 (I) (not shown). If the speed increases or decreases positive on negative halfcycles, Fig. 7 (II) and (IV) (not shown), are fed to the regulating field to boost or buck the main field. To synchronize at sub-multiplies of the fundamental synchronous speed, switches with two or more insulating segments may be used, Figs. 4-6 (not shown).

In cutting metals, a consumable electrode is continuously fed to an arc, shielded by an inert gas, struck between the electrode and the work, and the electrode and work are relatively moved to cut the work. A motor-driven trolley 14 runs on rails 15 and carries a reel 10 of ferrous wire which is fed by rollers 12 through a copper contact tube 13 to a head 18, which latter may be tilted for bevel cuts. Direct current is supplied to the tube 13 (positive) and argon is supplied to the tube from a cylinder. A selfregulating arc is established between the work, and the electrode and the head 18 is moved over the work. Alternatively the work may be moved and the head fixed or the head may be hand held. Ferrous metal, e.g. ferritic or stainless steel, may be cut as may be zinc and magnesium-zirconium alloy, and a wire of 18 per cent carbon, 44 per cent manganese, rest iron may be used for cutting aluminium or aluminium alloys. Alternating current with arc stabilization may be employed.
