Title: Lined bearing and method of making same
IPC: F16C33/14
Filed: 1928-07-27
Abstract: 320,943. Klocke, W. July 27, 1928. Bearings.-A lined bearing is made by cutting a rectangular blank from rolled steel or other metal sheet having high resilience and tensile strength, so that the grain is transverse thereof, bending the ends 7, Fig. 6, bending to U-shape in a die 5 and closing to cylindrical form by a pair of dies similar to, but having a slightly larger radius of curvature than, the die 5. The cylinder is then rotated through 90 degrees and again pressed in the dies to set the metal. To avoid the ends just meeting as shown at 11, 12, Fig. 9, the blank is made of extra length so that a close joint 10 is produced and the extra metal 14 is inside the cylinder 3. This may be removed by broaching or machining if desired. The cylinder 3 is then cleaned with acid, tinned and lined, with Babbitt or other bearing metal having a low melting point, by centrifugal casting or otherwise. It is then cooled rapidly to prevent annealing of the cylinder 3. The lined cylinder may be divided into halves for use.

Filed: 1973-05-09
Abstract: 1370755 Needling machine OSKAR DILO KG MASCHINENFABRIK 9 May 1973 [9 Feb 1973] 22018/73 Heading D1R In a needling machine metal foil 11, preferably reinforced with a woven or non-woven glass fibre fabric, replaces the conventional perforated plate. The fibrous web 10 is conveyed past the needle board 2 by endless belt 5. Web 10 is compressed prior to needling by between belt 5, shaped by metal support pad 8, and foil 11 shaped by vertically adjustable gate bar 14. As shown belt 5 comprises links 7 carrying steel or nylon pins 6 which contact web 10 and receive the tips of barbed needles 3 mounted on reciprocating needle board 2. Alternatively belt 5 may comprise a coarse textured bonded felt. In the position shown for support pad 8 the first row of needles 3 do not fully penetrate the web and thus act to pre-needle it. A greater degree of preneedling is produced by moving pad 8 to the right (Fig. 2, not shown). The holes made by needles 3 through stationary foil 11 do not unduly weaken it. Should it become torn or a different needle board be installed a new length of foil is drawn from roll 12.

Title: Improvements in or relating to a method of and an apparatus for taking and orienting cores
Inventor: BRADY EDWARD FAY
IPC: E21B25/16
Filed: 1950-09-07
Abstract: 676,171. Marking cores to facilitate orientation. EASTMAN INTERNATIONAL CO. Sept. 7, 1950. No. 22070/50. Class 85. In an assembly of equipment for orientating a core, a sub 13 is inserted between the drill pipe 11 and core barrel B, said sub having at the lower end thereof a plate 22 and in the walls diametrically opposed magnets 18, 19. When the torsion is removed from the drill pipe after a core C has been drilled and before it is broken free at the base, a surveying instrument S is dropped down the drill pipe for determining the angle of inclination of the bottom of the bore. Said instrument comprises a magnetic disc cup that carries a sensitised disc, the cup taking up a predetermined position with respect to the magnets. Above said disc is a pendulum having associated therewith a light source and lens and a time switch so that, on operation of the switch, a mark is made on the sensitised disc, the position of the mark enabling the calculation of the required angle to be made. A spring-loaded plunger 27 at the head of the instrument marks the plate 22 when the instrument is correctly positioned. On the outside of the sub is marked an index line 20 which lies in the vertical plane of the magnets and, when the assembly is hauled out of the bore, a clamp K is positioned about the sub with a spring-loaded plunger engaging an indent 21 on the index line, said clamp carrying a sighting bar 29 the plane of which is a horizontal one at right angles to the vertical plane through the magnets. Another clamp K<SP>1</SP> is secured about the drill bit D, said clamp having a tapered holder 40 in which is positioned an arm 42 carrying a telescope 41 by the aid of which the clamp is adjusted until the two arms lie in the same vertical plane parallel to one another. The arm 42 is removed from the holder and a scribe arm inserted therein, the scribe arm being so shaped that a horizontal limb thereof is thus positioned in the vertical plane through the magnets. Thus a line scribed over the base of the core, in conjunction with the information from the survey instrument, enables the core to be oriented on a reader when released from the barrel.

Title: Data signal input circuits
IPC: G11C19/18
Filed: 1973-05-09
Abstract: 1426905 Transistor switching circuits TELETYPE CORP 9 May 1973 [12 May 1972] 22073/73 Heading H3T A data signal input circuit for supplying data signals to a store, e.g. bucket brigade circuit 6, comprises a first gate 64 for applying input data 7 to a storage element 62 and a second gate 80 which controls the charge stored in element 62. If the data input at 70 is near earth potential, corresponding to a logical "1", application of a # 3  clock pulse at 72 turns on FET 64 to discharge capacitor 62 from -14 v. to 0 v. Subsequent application of a # 2  clock pulse charges capacitor 62 to- 10 v., allowing FET 80 to turn on and charge capacitor 62 to - 14 v. At the cessation of the # 2  clock pulse, capacitor 62 discharges until point 54 is at - 4 v., corresponding to a logical 1. A subsequent # 1  clock pulse then restores point 54 to- 14 v. and steps the data down chain 6. If the data input if negative, corresponding to a logical "0", the # 3  clock pulse does not turn on FET 64, and point 54 remains at - 14 v., so that FET 80 is not turned on by the next # 2  clock pulse. Capacitors 62 then charges to - 24 v. and discharges to - 14 v. at the end of the # 2  clock pulse, corresponding to a logical "0". Sequential application of # 1 , # 2 , # 3  clock pulses step the data through the shift register store 6 in a similar manner, each stage being reset to - 14 v. before the next data bit is applied to it. The output is applied to an amplifier comprising an inverter stage 8 and further stage 9, after which it may be applied to a further shift register 6<SP>1</SP>. If the # 3  clock pulse is not available an alternative input stage comprising FET's clocked by the # 1  and # 2  clock pulses may be used, Fig. 3 (not shown).

Abstract: 207,586. David, E. I., Flanders, G. F., and Williams, D. S. Aug. 18, 1922. Mine signalling systems. -In a bare wire signalling system, sparking at the signalling contacts is eliminated bv an overvoltage relay adapted to cut off the supply from the line, and a sensitive, relay is provided for operating a local signalling circuit. As shown, the sensitive relay comprises a coil 1 having a core 2 carried by a spring 3. When the signalling lines 19 are bridged, the core 2 is drawn up into the coil 1, and the member 5 bridges contacts 6 and closes the circuit of a visible or audible signal, e.g. the bell 20. This circuit is supplied from the source 21 which also supplies the lines 19. In order to adjust, the position of the core 2 to prevent its operation by leakage current, or so that the relay may be used on different voltages and with different resistances of the lines, the frame 7, which supports the spring 3, is adjustable by a cam 8 operated by a handle 9. Further adjustment is obtained by the operation of the nut 10. The over-voltage relay comprises a coil 11 having a core 12 carried by a spring which is secured to an adjustable support 13. The core 12 operates a contact 14 to shortcircuit the contacts 15, and therefore the lines 19, when the coil is energized by a predetermined voltage. When the contacts 15 are short circuited, a maintaining circuit is closed through the coils 1, 11. The initial movements of the core 12 are used to operate a pointer 16 which indicates leakage, or insulation or line resistance. The pointer may be rendered inoperative by a cam 24 operated by a knob 25. In a modification. the signalling and line circuits are supplied from separate sources. Also a single relay coil may be used ' for both circuits. The apparatus is enclosed in a metal flame-proof box 26. The Provisional Specification states that a buffer is provided in order to bring the core 2 to rest rapidly after each signal.

IPC: C01B31/26
Filed: 1965-05-27
Abstract: Carbonyl sulphide is prepared by passing carbon disulphide over a magnesia contact material at 200-500 DEG  C.  The magnesia contact material may be prepared by grinding magnesia with water, shaping the mass into particulate form and drying, and if desired calcining the particulate mass, e.g. at 400 DEG  C.  The product of the grinding is a partially hydrated magnesium oxide, and the initial magnesia preferably contains a decomposable salt of vanadium and/or thorium and optionally ammonium bicarbonate or oxalate.  In a continuous process, a mixture of carbon disulphide and carbon dioxide may be passed over the contact material or in a cyclic process, the passage of carbon disulphide may constitute the first step followed by the passage of carbon dioxide at 200-550 DEG  C. to convert magnesium sulphide formed in the first step back to magnesia.  The contact material may also be regenerated by passing steam over it at the reaction temperature. Unreacted carbon disulphide may be separated from the gaseous reaction products by condensation and/or absorption, and may be recycled and the carbon oxysulphide may be obtained 98% pure by fractional distillation.ALSO:A contact material is prepared by grinding light magnesia, mixed with a decomposable salt of vanadium and/or thorium and optionally ammonium bicarbonate or oxalate in the presence of water, shaping the mass into particulate form and drying.

Abstract: 1,042,745. Valves. SAUNDERS VALVE CO. Ltd. June 10, 1963 [June 12, 1962], No. 22608/62. Heading F2V. A diaphragm valve comprises a diaphragm 16, Fig. 1, which is clamped at its periphery between flanges 13, 17 on the valve body and the bonnet. The flange 13 is rounded at 14 to join tapered sides 15 which run into the cross-section of a through passage 12 to form a seating. The radius edge 14 lies inwardly of the edge of the flange 17 of the bonnet which is rounded into the wall 18 of the bonnet. The flange 17 extends inwardly a further amount over two opposite narrow zones to provide a greater radial width of clamping area. As shown in Fig. 2, this may be provided by portions 32 formed by chords which subtend an angle of about 36 degrees at the central axis. Alternatively, the zones may be formed by varying the radius of the rounded edge of the flange 17, preferably by a half, to provide the zones. Such zones subtend an angle of about 16 degrees and zones of an angular width of about 14 degrees provide a gradual change to the remaining edge. The diaphragm corresponds approximately to the seating in its natural state except that the tapered sides are not so steep and the diaphragm is stretched to provide full closure of the valve.
