Title: Method of forming an electrical contact
IPC: H01H11/04
Filed: 1969-04-15
Abstract: 1,269,559. Making electrical contacts. UNITED-CARR Inc. 15 April, 1969 [8 May, 1968], No. 19249/69. Heading B3A. A method of making an electrical contact comprises fastening the forward edge of a strip of gold foil on a metal support, cutting the foil a predetermined distance from the forward edge fastening the whole of the chip so formed to the support, forming the portion of the support at which the chip is attached into an arced configuration and then operating on the support to form the contact. The metal support comprises tinned phosphor-bronze strip or wire. The strip has indexing holes punched therein, Fig. 1 (not shown) and when at a first weld position the gold foil is advanced over the strip. As the leading edge of the foil is welded to the strip the chip is cut to length and then welded at a second weld haed. It is then passed to a die where the contact area is raised while the support is still in strip form. The strip is then passed to a progressive die to be formed into a socket contact by known means, Fig. 7 (not shown).

Title: Method of impregnating textile webs
IPC: D06M11/05
Filed: 1965-05-07
Abstract: In the dyeing, bleaching and finishing of webs of natural or synthetic textile materials, e.g. cellulosic fibres, by impregnation of the materials with aqueous compositions containing dyeing, bleaching or finishing agents, the materials are heated to effect vaporisation of the residual moisture contained therein and are contacted with the aqueous impregnation composition while the moisture is in the vaporized condition. The transition, from the heating zone to the impregnating liquid is preferably brief so that recondensation of the water vapour contained in the pores of the web is prevented or the intervening zone may be bridged by a steam-filled passage preferably extending fully into the impregnating liquid.  The web may first be subjected to condensation heating to vaporisation temperature in a steam or steam/air atmosphere to deposit moisture on the material, such condensation heating when applied to dry textile webs heated to a temperature of 20-100 DEG C yielding 5.5% additional moisture, with reference to the bone dry weight textile material, condensed on the web.  Vaporisation which then follows condensation heating is effected by condensation-free heating or heating by direct contact between the web and a heated drum.

Abstract: 147,231. Otto & Co., Dr. C. Jan. 3, 1916, [Convention date]. Coke ovens. - In a vertical-flued coke oven having foundation tunnels giving access to the regulating-valves of the gas burners, a regenerator chamber with a damper also accessible from the tunnel is associated with each heating-flue. The flues b, b<1> of a heating-wall are connected in pairs as shown, and each communicates at its lower end with one of a row of regenerator compartments d, d' beneath the ovens. Beneath the rows of compartments are flues e, e' having at one end dampered air-inlet ports and at the other outlet connexions leading through reversing-valves to the main flue e. The communication between each regenerator compartment and the flue e or e<1> is regulated by a damper block g or g<1>, which can be operated from the foundation tunnel. In one phase of operation, air and gas are supplied through the compartments d and burners c respectively: combustion takes place in the flues b, and the products are exhausted through the flues b', compartments d' and flues e<1>. On reversal, air and gas are supplied through the compartments d<1> and burners c<1>, and the products flow in the opposite direction. The connexions are so arranged that both rows of regenerator compartments beneath an oven operate in the same phase.

Title: Slide drawing machine
IPC: B23D33/00
Filed: 1974-05-02
Abstract: 1475751 Drawing; flying shears SCHUMAG SCHUMACHER METALLWERKE GmbH 2 May 1974 [3 May 1973 9 Nov 1973 28 Jan 1974] 19317/74 Headings B3P and B3W A slide drawing machine comprises at least two alternately reciprocable drawing carriages each carrying workpiece clamping jaws 2, blocking means 18 preventing full closure of the jaws 2 until the carriage has reached a predetermined position of advance and means for actuating closing means 13 of the jaws 2 before the predetermined position is reached. In one embodiment, each carriage is reciprocated by a rotating cam cylinder. The workpiece clamping jaws 2 of each carriage are attached to wedge members 3 which are connected to a driver 4 which is in turn connected by a pivotable lever 5 to toggle linkage 6-9 actuated by a piston and cylinder 13. During the return stroke of the carriage, an actuating signal is supplied to the cylinder 13 but its piston rod 12 is prevented from extending by a rail 18. The extension of the piston rod 12, causing closing of the workpiece clamping jaws 2, occurs as soon as the carriage passes the rail 18 during its forward stroke in a zone where it takes over from another carriage of the machine. The carriage is accelerated slightly in this zone. In other embodiments, the piston rod 12 is blocked by a lever (119) (Fig. 17, not shown) or a member (107) (Fig. 9, not shown) on the toggle linkage cooperating with a stop (108), and may extend in the drawing direction (Fig. 13, not shown). The drawn workpiece is cut by a tool 206 Fig. 21 mounted on the upper 202 of a pair of slides 201 202. When the leading end of the workpiece passes a fixed sensor 217, a clutch 211 is operated after an automatically variable delay causing a cam cylinder 209 to be rotated which reciprocates the slides 201, 202. When a strip (220) (Fig. 24, not shown) on the cam 209 passes a sensor (221), an electronic angle transmitter responsive to the position of a control finger 223, which is contacted by the leading end of the workpiece and which is connected by a rod 228 to the upper slide 202, causes a piston and cylinder 207, 208 to adjust the relative positions of the two slides 201, 202 until the finger 223 is in a particular position (T) (Fig. 25, not shown) whereupon the desired length of workpiece to be cut is set. During the further advancement of the slides 201, 202, the cutting tool 206 is actuated by a lever 214 when a lever 213 engages a roller 222.

Title: Improvements in or relating to separation processes by distillation
IPC: B01D3/14
Filed: 1960-06-01
Abstract: <PICT:0896464/III/1> In a distilling process for separating the components of a mixture of substances capable of separation by distillation, e.g. a mixture of light hydrocarbons, the feed to the distillation column is prepared by intimately contacting the mixture with the overhead vapours of the column to establish a gas-liquid equilibrium, cooling and condensing the gas and liquid phases which are in equilibrium and separating the liquid together with the condensate, the separated liquid then being employed as the feed. As shown, the column 2 is operated under pressure and is divided by a draw-off tray 3, adapted to pass vapour but not liquid, into a distillation section 4 and a mixing section 5, the latter being provided with bubble cap trays 6 and 7 or other contact means adapted to effect fine distribution of one phase in the other and effect a gas-liquid equilibrium.  A mixture of C1-C4 hydrocarbons is passed through line 1 to mixing section 5. C3 and C4 hydrocarbons are withdrawn from the base of the distillation section at 8.  The vapours and liquid are withdrawn from the mixing section 5 at 9 and 10 respectively and are passed together through a cooler 11 where more liquid condenses.  The gases and liquid in the cooler (which are no longer in equilibrium) are passed separately to an accumulator 14 through lines 12 and 13 respectively.  In the accumulator the liquid and gases move countercurrently through the packed dome 15 and equilibrium is again established between them.  C1 and C2 hydrocarbons are withdrawn at 17 and the accumulated liquid is withdrawn at 18 and returned, as fed, to the distillation section 4.

Title: Method of improving piezo-electric crystals
IPC: H03H3/02
Filed: 1928-07-06
Abstract: 314,680. Russell, E. W. C., (Sawyer, C. B.). July 6, 1928. Piezo-electric crystal u n i t s - Composite crystals particularly those of Rochelle salt with opaque end portions containing occluded liquid, are improved in their piezo-electric action by removing the opaque portions and replacing them by solid or other permanently and uniformly conductive material. As shown in Fig. 4, the opaque portions 1 are removed by boring holes 3 in the base of the crystal 2 and blowing the liquid matter 1 through the holes by air pressure applied through the pipe 6. The crystal rests on a gasket 4 in a closed chamber 5, the air and the liquid material escaping through an aperture 7. The crystal may be heated during the process. The liquid is replaced by conductive material, which may comprise a silver nitrate solution. This is placed in, or sucked into, the end portions 1, and on exposure to light metallic silver is deposited. Alternatively, the portions 1 may be filled with a conducting liquid such as varnish. In Fig. 7, the crystal has one end portion filled with conducting material 13, such as tin foil, amalgam, or powdered graphite, whilst the other is lined with tinfoil 14. The cavities formed in the end portions of the crystal may be of greater extent than the opaque portions of the original crystal. The crystal may be mounted in a cradle 15, Fig. 9, fixedly at one end 20, and pivotally at the other end 22. The conductive end portions 18, 19 jointly form one electrode, and a band 9 wrapped round the crystal forms the other electrode. Voltages applied to the electrodes causes torsional stress in the crystal, so that a lever 21 attached to the crystal is given a pivotal movement about the axis 22.

Title: Safety device for a runaway vehicle
Inventor: MCALLISTER THOMAS
IPC: B61K7/22
Filed: 1969-04-18
Abstract: 1,269,231. Railway stops. COAL INDUSTRY (PATENTS) Ltd. 9 June, 1970 [18 April, 1969], No. 19833/69. Heading B7L. [Also in Division F2] A safety device 2 for arresting a runaway  railway vehicle comprises arrest means 10 for engaging an axle 40 of the vehicle, and a clamp assembly 24 which comprises jaws 30, 32 having friction pads 36, 38 engageable with opposite sides of the web of an I-section girder 4 such that in operation when the arrest means 10 engages the axle 40, the clamp assembly 24 slides along the girder 4 in the direction of vehicle travel, and acts to brake the vehicle. As shown, the arrest means 10 is formed by two members 12 pivotally mounted on a pin 14 passing through a slot 15 extending along the web of the girder 4 which is rigidly secured to metal sleepers 6 of the track 8 and each member 12 comprises a straight arm 16 of a single thickness of metal and a heavier hook-shaped arm 18 of double thickness of metal. The clamp assembly 24 includes double-limbed arms 20, 22 and when the members 12 are in the vehicle arresting position of Fig. 2, the arms 18 abut against the limbs. In operation, the arms 16 are normally uppermost, but each time the members 12 are struck by a leading axle of the vehicle they are depressed and the arms 18 become uppermost. If the vehicle speed is low the members 12 return to their normal position before the rear axle 40 of the vehicle reaches the arrest means 10, but if the vehicle is moving rapidly the arms 18 will engage with the axle 40, and the arrest means 10 will be moved along the girder 4 with frictional engagement of the pads 36, 38 and the girder 4. The arrest means 10 may then be returned to its initial position on the girder 4 manually by unscrewing a bolt 34 which holds pads 36, 38 in contact with girder 4, or automatically by the action of a coil spring extending parallel to the girder 4.
