Title: Tuning fork digital accelerometer
Inventor: SOUTHWORTH HAMILTON
IPC: G01P15/10
Filed: 1966-08-18
Abstract: 1,144,841. Measuring acceleration electrically. GENERAL PRECISION SYSTEMS Inc. Aug.18, 1966, No. 37094/66. Heading G1N. A vibrating wire accelerometer comprises two similar wire assemblies caused to vibrate at their natural frequencies, supported coaxially by inertia masses, whereby acceleration in the axial direction produces a differential change in vibration frequencies which is indicative of acceleration. As shown Fig. 2, two inertial masses 28, 30 are supported centrally by metal strips 32, 34 in a cylindrical housing 22. One pair of ferromagnetic tines 40 is supported between mass 28 and the housing end-face 24, and a second pair of tines 42 between mass 30 and the other end-face 26. Driving coil 60 and pick-up coils 64, 66 are associated with tines 40 in an amplifier circuit 80 Fig. 4 so that the tines vibrate at their resonant frequency Wo, a similar circuit being associated with tines 42. When the assembly is subjected to an axial acceleration the tensions in the tines vary differentially to charge the frequencies to W 1  and W 2 , and these are mixed at 84 to give (W 1  + W 2 ) and (W 1  - W 2  which are multiplied together at 96 to give (W 1 <SP>2</SP> - W 2 <SP>2</SP>), which is proportional to the applied acceleration. In another embodiment Figs. 5-10 (not shown), only one pair of tines may be used, made of goldplated quartz and vibrated electrostatically.

Title: Improvements in thermionic cathodes
IPC: H01J1/14
Filed: 1929-12-05
Abstract: 334,460. Westinghouse Electric & Manufacturing Go., (Assignees of Halliwell, G. P.). Dec. 14, 1928, [Convention date]. Vacuum tubes.-A cathode consists of a homogeneous body containing one or more metals of the nickel group, a deoxidizing agent such as titanium, thorium, vanadium, tantalum, silicon, manganese, aluminium, or cerium, zirconium or other metals of the rare earth group, together with one or more alkaline earth metal oxides disseminated throughout the body. A salt or a mixture of salts of the alkaline earth metals such as nitrite, nitrate or oxalate is added to powdered nickel or nickel oxide forming a suspension of nickel &c. in an aqueous solution of the salt. The water is evaporated and the mass roasted in an oxidizing atmosphere to convert the salts to oxides. Nickel oxide if present, is reduced as by heating in hydrogen, and the mixture is ground to a fine powder, mixed with the deoxidizer, pressed into slugs which are heated to produce sintering and recrystallization in a vacuum, or an inert or reducing gas. The slugs are then formed into wire in the usual way. Sulphur should be excluded. The proportion of alkaline earth oxides is preferably 2-4 per cent, and should be below 10 per cent. The proportion of deoxidizer should be 0.5-10 per cent. A suitable proportion is 2.5 per cent of titanium and 3 per cent of barium oxide or of a mixture of barium and strontium oxides. Instead of nickel an alloy known as konel consisting of 70 per cent of nickel, 20 per cent of cobalt, 7.5 per cent of iron and 2.5 per cent of titanium may be used.

Title: Improvements in the production of combustible gases
IPC: C10J1/207
Filed: 1962-10-09
Abstract: <PICT:1016721/C4-C5/1> Combustible gases are made by the pressure gasification, e.g. at 20 to 35 atmos. gauge, of finely divided solid fuel in suspension with oxygen, with or without water vapour, the fuel being introduced into the high pressure system pneumatically by a gaseous medium, e.g. nitrogen or air, compressed above the operating pressure.  The solid fuel is delivered from a bunker 3 through a non-return element 35 to a high pressure injector 7 and is fed by a pipe 9 to a dust separator 10 by the gaseous medium which is returned via filter 12 to a compressor 8. The fuel, now under operating pressure, is mixed with oxygen from a compressor 18 and, if desired, water vapour from a boiler 21, prior to entering the gasification chamber 17.  Dust separated at 12 is returned to the bunker 3, and loss of carrier gas (e.g. at 10, 12) is made up by the system 28 ... 33.  In a modification, Fig. 2 (not shown), a pressurized container which is periodically charged replaces the injector 7, a valved pipe which by-passes the container permitting continuous cyclic flow of the gaseous medium during charging of the container.  Alternatively, the container can be made to operate continuously by inserting a sluice tank in the fuel line after the bunker 3 and before the container (see Fig. 3, not shown) or two containers may be provided and used alternately.

Title: Machine for the manufacture of paper bags with diamond-shaped bottoms

Filed: 1957-12-12
Abstract: 845,606. Paper bag making machines. RAWE, M., [trading as MASCHINENFABRIK M. RAWE]. Dec. 12, 1957 [Dec. 13, 1956], No. 38612/57. Class 94(2). In a machine for making paper bags with diamond-shaped bottoms from flattened paper tubes fed transversely to their longitudinal axes, the folding devices which form the bottoms at both ends of each tube portion are arranged inclined to each other so that their working planes form acute angles with the plane of the tube. The two devices for applying adhesive after the folding operation are arranged in sequence in the direction of feed of the tubes. A flattened paper tube is fed transversely of its longitudinal axis between feed rollers 2, 3, Fig. 1, where grooving rollers produce fold lines towards each end of the tube. Between positions II and III, the ends of the tube are bent downwards about the grooved lines through less than a right angle, and in this state, the ends 1<SP>1</SP>, 111 of the tube 1 are each passed between pairs of suction nozzles 61, 6<SP>11</SP>, Fig. 3, where both ends of the tube are opened and spread. The nozzles 61, 6<SP>11</SP> are rotated, respectively, about inclined axes 6a, 6b in known manner. A rotating spreader finger (not shown) enters the open mouth at each end of the tube to open the mouth still further. At position IV, folding devices 7, 71, Fig. 4, form the bottom squares la, 1b of the expanded tube ends 1<SP>1</SP>, 111. These devices includes folding fingers 7a, 7b guided on endless chains so that they move with the tube along its support, and are guided to perform a swinging motion so that they enter the expanded ends 1a, 1b. The folding action takes place in a plane which forms an acute angle d with the plane of the tube 1, the folding devices being mounted on inclined carriers on the machine frame 9, 91. By this inclined arrangement, the folding devices 7, 71 can be disposed closer together than known devices, so that the distance a between the fold grooves on the tube can be made considerably smaller. On leaving the folding devices, the formed bottom squares 1a<SP>1</SP> 1b are tilted into the horizontal position, and guided through two adhesive applying devices 12, 121 at positions V and VI; these are arranged to act in sequence on the bottom squares, owing to the short length of the bag tube. Each end of the tube passes between a wide bottom adhesive applying roller and four narrow upper support rollers. At position VII, grooving rollers act simultaneously on the bottom squares 1a, 1b so that the latter can subsequently be folded, in known manner, to form diamond-shaped bottoms. A venting valve can be inserted during this forming operation.
