Abstract: 668,465. Electrolytic production of fluorine. PENNSYLVANIA SALT MANUFACTURING CO. June 24, 1948 [June 28, 1947; Sept. 13, 1947; Sept. 13, 1947], Nos. 17058/48, 17059/48 and 17060/48. Class 41. In an electrolytic cell structure suitable for the production of fluorine, comprising a vessel for containing an electrolyte, an anode of non- graphitic electrode carbon extending downwardly into the electrolyte, a downwardlyextending cathode spaced from the anode and being either solid or containing louvres slanting upwardly away from the anode, and a barrier impervious to gases extending downwardly between the anode and cathode but to a lesser depth, the minimum horizontal anode and cathode spacings, as measured between the electrode in question and a vertical line extending down from that portion of the lower edge of the gas barrier which serves to separate gases ascending through the electrode, are related to the depth of the electrodes below the lower level of the gas barrier, substantially as indicated on the graph shown in Fig. 3, the abscissµ representing spacing in inches and the ordinates representing electrode length below the barrier level. The curve A-1 shows the minimum anode spacing and A-2 the preferred minimum anode spacing. Curves C-1 and C-2 correspond to the anode curves A-1, A-2, respectively but relate to a louvred cathode, and curves C-3, C-4 relate to a solid cathode. As shown in Fig. 1, a tank 11 surrounded by a jacket space 13 for a heating or cooling medium, is filled with potassium fluoride and hydrogen fluoride up to a level 12. Into the electrolyte depend a non-graphitic electrode carbon anode 24, gas barriers 19, and louvred cathodes 16. The connecter 21 for joining the anode to a source of current is screwed into a metal plate 27 which is provided with bolts 28 screwed into the anode. The connecter 21 and plate 27 are preferably made of copper or beryllium copper alloy. A compound such as a water-based graphite paste may be used between all abutting surfaces of metal and carbon. The temperature during electrolysis is maintained within a range of about 95 to about 105 C.

Title: Improvement in Methods and Apparatus for Eliminating Undesired Vibrations of Particular Frequencies.
Inventor: FESSENDEN REGINALD AUBREY
IPC: H03H9/46
Filed: 1917-11-20
Abstract: 129,670. Fessenden, R. A., and Leslie, F. H. June 8. 1917, [Convention date]. Telephone systems and apparatus. - Undesired vibrations of particular frequency, such as the natural frequency of a diaphragm. are minimized by the use of an element adjusted tc absorb vibratory energy at the particular frequency. The invention is applicable to diaphragms of sound receiving apparatus such as telephones. Electrical and mechanical embodiments are described. As shown in Fig. 3, the invention is applied to an oscillator 22 of the kind described in Specification 18765/13 used in subaqueous signalling or telephony. As manufactured, this oscillator is markedly responsive to two particular frequencies, and the undesirable resonance effect is eliminated by the use of two tuned circuits, one comprising an inductance 23, resistance 24, and capacity 25 adjusted for one frequency and the other comprising an inductance 26, resistance 27, and capacity 28 adjusted for the other frequency. When so shunted and connected with a telephone transmitter 21, the oscillator 22 can be used for transmitting speech through water. Fig. 4 shows a mechanical application to a rotary shaft which vibrates when a particular speed of rotation is reached. A cylinder 45 is mounted so as to be free to oscillate on a piston having apertures 41, 42 and connected to the shaft by a rod 38. The dimensions of the parts are so chosen that when the critical speed at which vibration occurs is reached, the cylinder oscillates, energy being absorbed by the throttling effect of the apertures 41, 42 on the air passing in and out. The rod 38 is connected to the shaft through an eccentric 37 which is stated to minimize lateral movement of the rod due to bending of the shaft. In other applications, the rod 38 is connected to the diaphragm or other vibrating body.

Title: Improvements in or relating to the production of shaped products by melt spinning
IPC: B29C48/05
Filed: 1958-05-29
Abstract: <PICT:0861888/IV (a)/1> <PICT:0861888/IV (a)/2> Artifical filamentary and other shaped products are produced from powdered fusible filament - forming materials by a process which comprises compressing a powder of the filament-forming material by means of a rotatable feed-screw to form a solid block or pellet within a substantially tubular member, forcing the block or pellet by rotating the screw at a constant speed against a spinning plate having one or more spinning orifices and maintained at a temperature sufficient to melt the filamentforming material over a thin layer of the block adjacent to the plate, and drawing the resulting filamentary or other shaped structure from the spinning orifices either positively or by their own weight, the rate of rotation of the screw and the temperature of the plate being so correlated that the material is fed to and extruded through the orifices in the plate at a speed equal to that at which it is melted.  The filament forming material is preferably cellulose triacetate and the spinning plate may be maintained at a temperature of 350-400 DEG  C.  Apparatus suitable for use in the above process comprises a spinning plate 25 arranged to be heated electrically and opening into a free space in which filaments formed thereby are solidified by cooling, a substantially cylindrical member 16 arranged to be kept at a temperature substantially lower than that of plate 25 (e.g. by diffusion of heat through insulators 26, 27 to cylindrical member 16), a rotatable screw 1 at least partly contained and fitting closely in cylindrical member 16, and means for supplying powdered filament forming material to cylindrical member 16, e.g. a hopper composed of an upper cylindrical portion 18 and a lower conical portion 19.  The feeding end of screw 1 may be spaced from plate 25 by between 1/3 and 2/3 of the screw diameter. Preferably the cylindrical member 16 is slightly flared, e.g. by an angle of 1 to 3 degrees from the plate 25 upwards to facilitate downward movement of a block of filament-forming material.  Hopper 18, 19 is fitted with bearing means adapted to resist axial displacement.  The filament-forming material may be kept under a vacuum or an inert gas until it leaves the extension orifices. The filaments or other shaped structures may be drawn away from the orifices of the spinningplate by use of conventional means. Specifications 534,243, 719,853, 721,674 and U.S.A. Specifications 2,605,502 and 2,657,430 are referred to.

Title: Improvements in and relating to in-situ concrete piles
Inventor: MURRAY JOHN BRITTON
IPC: E02D5/46
Filed: 1950-07-11
Abstract: 694,242. Piles. GAMMON (MALAYA), Ltd. June 25, 1951 [July 11, 1950; March 1, 1951], Nos. 17300/50 and 4952/51. Drawings to Specification. Class 68(ii) Concrete piles are formed in situ by driva hole in the ground, and filling the hole with aggregate and a separately supplied intensely mixed grout of cement, sand and water capable of flowing into the voids of the aggregate and into the interstices in the face of the hole. The grout may be prepared in a machine as described in Specification 536,444, [Group V] and 694,117. [Group II], such a grout being capable of building up a hydrostatic pressure and being not readily miscible with water. The hole is driven. by a tube with a shoe at the lower end. The tube is invariably withdrawn, abandoning the shoe, but it is preferred that the aggregate and grout should be fed in before the tube is extracted. The aggregate and grout may be supplied simultaneously or alternately in small quantities,.or the hole may be filled with aggregate before the grout is supplied. The penetration of the grout into the voids of the aggregate may be assisted by applying air pressure at the top of the tube above the aggregate and grout, and such air pressure may be used for extracting the tube, or it may be used for producing a mushroom or bulge at the bottom of, or at any desired locality in, the pile. Further grout and aggregate may be supplied to the tube at stages during its extraction. If the hole, or the tube, is completely filled with aggregate before the grout is supplied, it is preferred to arrange an axial tubular perforated member, e.g. of expanded metal, in the hole or tube, sc that the grout is supplied to all levels in the aggregate. The axial member may be attached to the shoe and the grout may be supplied directly to the member, or a feed tube may be lowered to reach the bottom of the member. If a nest of piles is to be formed, a number of holes are driven in the ground, each hole being filled with aggregate after it has been formed, thereby preventing the driving of an adjacent hole from collapsing the previously driven holes. The grout is then supplied to all, or a number of the aggregate filled holes. Alternatively, concrete pipes of slightly less diameter than the inside of the tube are lowered into the tube and superposed until they reach ground level, the pipes being subsequently filled with aggregate and grout, the latter leaking to the outside of the pipes to fill the interstices in the sides of the hole. The shoe may be sealed to the bottom of the tube by a rope soaked in bitumen, and a cage of steel reinforcement may be lowered into the tube.

Filed: 1936-06-24
Abstract: 464,548. Controlling aircraft. JUNKERS-FLUGZEUGWERKE AKT.-GES. June 24, 1936, No. 17539. Convention date, July 2, 1935. [Class 4] In an aeroplane adapted for dual control the entire control system consisting of the actuating members, the transmission means and the control surfaces are divided into halves which are independent of one another, but which can be operated simultaneously from either control post. In one form, Fig. 1, control columns 1a, 1b are mounted on transverse rockshafts which can be connected or disconnected by a clutch 63, 64. Levers 1a, 1b are coupled by rods 22a, 22b to elevators 20a, 20b the rock shafts of which may be connected or disconnected by a clutch 66, 67. Columns 1a, 1b carry aileron control wheels 3a, 3b of which the movement is transmitted to starboard aileron 40a and to port aileron 40b, respectively. Aileron control shafts 44a, 44b may be coupled by a clutch 71, 72, so that operation of either control wheel will adjust both ailerons. Rudder bars 2a, 2b actuate rudders 30a, 30b, the rudder bars being coupled by a rod 36 and the rudders by a rod 38, which can be removed during flight if necessary.

Filed: 1962-05-07
Abstract: 952,707. Making electrical contact points. FANSTEEL METALLURGICAL CORPORATION. May 7, 1962 [May 8, 1961], No. 17554/62. Heading B3A. [Also in Division B5] A method of producing electrical contact discs, for use as contact points, from a rod of contact material comprises rotating the rod, bringing the rod and a line cutting device into cutting relationship and effecting relative movement between the device and the rod in a plane at an acute angle to the axis of the rod to cut it along substantially one half a chordal length at the depth of cut. A rod 3 of tungsten or other refractory metals is supported in a motor driven spindle housing 2 by a collet 4 and fed to a stop 12 by pneumatic or other means (not shown). Mounted on the same base as the rod assembly is a cut off wheel drive assembly comprising a motorized spindle 17 on which is mounted a thin fibre or steel disc cut-off wheel 14, a housing 18 slidably mounted on table 16 pivoted at 15 and an hydraulic motor 26 which swings the table 16 about the pivot 15, the axis of which intersects the axis of the rod 3 at right angles. To cut off discs having conical end faces the table assembly 16 is disposed and locked at an angle less than 90 degrees to the rod axis and the wheel assembly 14 fed towards the rod 3 by an hydraulic motor 19 to cut off the end disc and produce a conical face on the end of the rod and a concave face on the cut-off end face of the disc. The subsequent cutting-off of the following disc produces one with a conical and concave end faces. Discs with two conical ends are produced by displacing the axis of the wheel 14 one half of a wheel diameter in a plane perpendicular to the plane containing the axes of the wheel and rod or by using a releasable collet for holding the end of the rod in contact with the step 12 until the wheel has travelled the full diameter of the rod to cut a conical face on the back of the severed disc. To produce a spherical radius on the rod the cut-off wheel assembly angular relationship with the rod is continuously varied up to 90 degrees. The contacts may be finally tumbled to produce rounded edges as necessary. Alternatively an oscillating saw blade may be used.
