Title: Improvements in or relating to electromagnetic relays
IPC: H01H50/16
Filed: 1930-07-22
Abstract: 353,689. Electromagnetic switches and light current relays. PANIAGUA, Y. M. L. DE, 25, Rue de Madrid, Paris. July 22, 1930, No. 22039. Convention date, July 22, 1929. [Class 38 (v).] An ironclad electromagnetic relay has the coil 15 wound on a non-magnetic tube 16 and mounted within a soft-iron cylinder 9 fitted at one end with a flanged soft-iron disc 4 and at the other end with a recessed soft-iron disc 11. The central core is made in two parts 1, 2 separated by a piece of non-magnetic material 3, the portion 2 being clamped to the endplate 11. Opposite the piece of non-magnetic material 3 which forms the break in the magnetic circuit of the relay is mounted a magnetic armature 23 on a blade-spring 7 secured at one end to the core portion 1 and carrying a contact 24 at its free end. The adjacent ends of the core members 1, 2 are notched as shown in Fig. 3 so that when the coil is energized a flux distribution is shown causing the armature to move to engage the flat portions at the bottom of the notches so bringing contacts 24 into engagement. The disposition end of the armature at the centre of the core shields it from the action of stray fields. The winding connections may pass to insulated plugs 17, Fig. 2, engaging sockets in a detachable insulating block secured at one end of the relay, the block carrying plug members 21 for connecting the relay in circuit.

Title: An improved elastic suspension for vehicles
IPC: B60G11/14
Filed: 1933-08-09
Abstract: 415,577. Vehicle spring-suspensions; hydraulic springs. CARLEVERO, G., 6, Via Paletta, Novara, Italy. Aug. 9, 1933, No. 22302. [Classes 108 (ii) and 108 (iii).] A vehicle suspension of the hydraulic-mechanical type comprises one or more sets of telescopic cylinders pivoted to the chassis and to the wheel axle each set being in fluid connection with a cylinder comprising main and check spiral springs and movable members or tubes operated by the hydraulic pressure. One or more cylinders A, A<1> are mounted on the axle 14, Fig. 1, while the telescoping or overriding cylinders O are connected to the chassis X so as to be able to oscillate in a plane at right angles to the plane of oscillation of the cylinders A. Each of these sets is connected to a member C carried by the body or chassis by a pipe Tf. Relative movement between the chassis and axle causes the cylinder O to telescope a cylinder A and by means of a rod y, Fig. 5, drives a piston 6, a closure device Z<1> and the piston 7. The latter piston moves a tube 31 with its disc 33 and forces the pressure fluid along pipe Tf to the member C where it forces forward the piston 7 and with it the ball 4' of the closure device Z<2>, piston 6, sleeve 31 with its disc 33. The latter through a rod y forces forward the piston 26, ball 4<2> of the closure device Z<1>2 and piston 27 driving the fluid in chamber S' to urge the piston 16, ball 4<3> and piston 17 forwards and by means of the rod 5, connected to a cup G secured to the tube T moves the latter to the left. This movement compresses the springs M against the abutment L<1> and unloads the check springs M'. These springs give the suspension for the normal oscillations of the vehicle. When however excessive shocks are imparted to the suspension the springs Mare locked and the reactive pressure of the liquid between closure devices Z<1>2 and Z<3> acting on the shoulder b of chamber S' forces the tube N to the right and by means of the disc T<a> rods r, stirrup V compresses the check springs M' so that the periodicity of the springs is changed and an aperiodic suspension is obtained. To ensure tightness of the balls of the closure devices they are forced into the tubes and the pistons 6, 7 are provided with segmental extensions 6<1>, 7<1> acting on opposite sides of the diameter so as to cause the balls to roll and to vary the axis of rolling.

Abstract: 822,503. Making heat-exchangers and pipes; rolling; stamping; welding by pressure; working at specified temperatures. OLIN MATHIESON CHEMICAL CORPORATION. July 19, 1956, No. 22402/56. Classes 83 (2) and 83 (4). A method of making pipes, heat-exchangers, doors and structural parts which includes assembling metal sheets face-to-face, securing the sheets against relative slippage and rolling the assembly to elongate, to forge weld and to reduce the thickness, and in which at least one of the metal sheets is folded inwardly along an edge or a pair of opposite edges to form laps, the laps being in contact with the remainder of the folded sheet, and in which the folded sheet is assembled with a second metal sheet lying on the exposed surface of the lap or laps of the folded sheet, the lap or laps of the folded sheet being forge-welded by the rolling to the second sheet. The unwelded interfaces are subsequently separated by expansion with fluid pressure. A stop-weld material may be included between the laps or between the sheets. An aluminium sheet 1, 0.025 inch thick, is cleaned and coated with stop-weld 2, Fig. 2, and the edges 3 and 6 are inwardly lapped. A sheet 9, Fig. 3, is spot-welded to the sheet 1 and the assembly is hot-rolled at about 540‹ C. in a reducing atmosphere, the thickness reduction being about 60-65%, to pressure-weld the sheet 9 to the laps 3 and 6 and also to weld the sheets along the other edges. Subsequent cold rolling may further reduce the thickness. Fluid pressure is then introduced to the unwelded interface and a pipe as shown in Fig. 7 is produced. In a modification, tubes of the type shown in Fig. 8 may be made using sheets 1 and 12, Fig. 4. In another modification an additional sheet 17 may be introduced between sheets 1 and 12, Fig. 9, so that it becomes welded to sheet 12 and forms a tube with half its wall thickened. Alternatively a sheet 18 may be pressure-welded to and between the laps of sheets 1 and 12, Fig. 11, to form a multiple-bored conduit. In another modification, the laps abut so that the sheets 1 and 12 are doubled, Fig. 13, the bands of stop-weld being spaced by longitudinal gaps 22 which may be straight or tortuous. On inflation, multiple units are produced. Fig. 15 shows a two-part die 20-21 in which the slightly larger assembly is diagonally placed so that on inflation a rectangular article is formed. The assembly may be placed horizontally in which case parts 20 and 21 of the die are separated, coming together as the assembly conforms to the die on inflation. Sheets of copper, bronze, brass or steel may be used. A 50% thickness reduction is stated to be necessary to weld copper alloy. Reference has been directed by the Comptroller to Specification 795,994.

Title: Improvements in or relating to apparatus for inscribing a pattern in a sheet of material
IPC: H01J31/64
Filed: 1951-09-27
Abstract: 705,028. Electric beam apparatus. RAULAND CORPORATION. Sept. 27, 1951 [Sept. 27, 1950], No. 22563/51. Class 39(1) An apparatus for inscribing a pattern in a sheet of material having a given secondary emission characteristic comprises means for directing a beam of charged particles (e.g. electrons) towards an elementary area of the sheet and means for deflecting the beam to a further elementary area in response to a signal produced when the secondary emission of the first area is altered due to bombardment of the beam. The apparatus may be used to form the mosaic screen of a storage tube 10, Fig. 1. A rectangular plate 13 of quartz, glass, or mica, coated with a metallic layer 12, which may be of silver or copper, is mounted in the tube and one of the electron guns is used to bombard the metal layer so as to melt it at the point of impact of the beam. When the layer melts the secondary emission changes and a pulse is developed in the load 28 and fed through a pulse separator 29 which is coupled through an integrator and a D.C. amplifier to the horizontal deflection coil 34 so that the beam is deflected on to the next elementary area to be treated. At the end of a line the beam is moved off the edge of the screen and a pulse with a sharper leading edge is developed in the load 28; the pulse separator 29 feeds these sharper pulses through a similar integrator and amplifier to the vertical deflection coil 43, so that the beam is moved down to the next line, and at the same time discharges the horizontal integrator so that the beam is moved back to the beginning of the line. When the whole screen has been scanned the vertical integrators may be discharged by manually operating a switch 46, thus causing the whole cycle of operation to be repeated. The load 28 is also coupled through a discharge device 50 and integrator 51 to a relay 27 which is so arranged that when, after the scanning has been completed, the beam moves off the screen altogether the relay lights a warning lamp 56 and applies a negative bias to the electron gun to cut off the beam. When the screen has been processed in this way the tube may be used as a storage tube. Specification 677,300 is referred to.

Title: Method of producing high octane gasoline components
Inventor: HODGSON ERNEST
IPC: C10G59/04
Filed: 1956-07-24
Abstract: High octane gasolines are obtained by blending various gasolines with a thermally reformed fraction obtained from a straight run gasoline by catalytically reforming in the presence of a platinum catalyst on an acidic carrier, distilling the reformate to obtain a lower boiling fraction boiling below 160 DEG  C. and having an octane number lower than the higher boiling fraction and subjecting the lower boiling fraction or part thereof to a purely thermal reforming process to increase its octane number (see Group IV (b)).  The gasolines with which this thermally reformed fraction may be blended are the heavier fractions from the catalytic reforming, similar fractions from other catalytic reforming process, other thermally reformed fractions from catalytic reformations, light or full range fractions from catalytic reformations, thermally reformed gasolines, straight run gasolines, catalytically cracked gasolines, isopentane, polymer gasolines and alkylate gasolines.  Suitable fractions of catalytically cracked gasolines, preferably boiling in the range 40-110 DEG  C. may be blended with the thermally reformed fraction with or without fractions from catalytic reforming operations.  In examples: (1) after catalytic reforming of a straight run naphtha the product was distilled cutting at 132 DEG  C.  The lower boiling fraction (38 per cent by weight of the reformate) was thermally reformed and a high octane gasoline prepared by blending 20 vol. per cent of the thermally reformed fraction, 30 vol. per cent of the heavy reformate, 46 vol. per cent of a volatile catalytically cracked gasoline having a boiling range 45-105 DEG  C. and 4 vol. per cent of butane.  (2) The catalytic reformate was distilled to give a light (up to 85 DEG C. 25 parts by vol.) a middle (85-132 DEG  C., 25 parts by vol.) and a heavy fraction (above 132 DEG  C. 50 parts by vol.).  The middle fraction was thermally reformed, debutanized and blended with the light and heavy fractions in production ratio (vol. ratio 3 : 5 : 10) to give a gasoline with a boiling range of 45-205 DEG  C. and a research octane number of 96. Specifications 657,565, 686,641, 732,189, 742,769 and 794,650, [three in Group IV (b)], are referred to.

Title: An improved process for manufacturing tools of homogeneous alloys of great hardness
IPC: C22C1/05
Filed: 1929-07-25
Abstract: 331,121. Brewer, G., (Krupp Akt.-Ges., F.). July 25, 1929. Compound forms; lathe tools.-Tools of great hardness, such as turning tools, are made by melting a mixture of metals of high melting point, such as chromium, molybdenum, titanium, tungsten, uranium or vanadium, and metalloids such as carbon, boron or silicon, with or without other metals such as iron, cobalt or nickel, then cooling to produce a finely grained texture, then finely powdering, then pressing to form the tool and subsequently or simultaneously sintering by external heat or resistance heating at a temperature which does not destroy the fine texture, e.g. 1500‹ to 1900‹ C. 400 grms. of powdered tungsten may be mixed with 40 grms. of titanium carbide and melted electrically in a carbon crucible having carbon terminals, in a hydrogen atmosphere. The melt is poured into a watercooled copper mould and is then powdered and shaped in swages under a pressure of 4000 kgs. per sq. cm. The shaped bodies are sintered for 12 minutes at a temperature of 1750‹ C. in hydrogen below atmospheric-pressure, cooled down to 1500‹ C. in 40 seconds and then allowed to cool to room temperature in 45 minutes. The additional metals or the metalloids may be introduced into the mixture during melting after pouring from the crucible. The pressing operation may include the formation of holes or recesses in the tool. The bodies may be immediately subjected to a further heat treatment between 1000‹ C. and 2000‹ C. to improve the texture and may also be subjected to mechanical treatment such as forging, rolling, pressing, &c. at 2000‹ C. The alloy may contain tungsten with less than 3 per cent of carbon. Specifications 157,747, 157,749. 294,086, [all in Class 83 (iii), Metals, Cutting], and 310,885, [Class 82 (i), Metals, Extracting &c.], are referred to.
