Filed: 1997-02-03
Granted: 2000-04-24
Abstract: A diaphragm-type valve uses a multiple annular metal diaphragm (36) welded about its inner periphery to a valve operating stem (34). The diaphragm is sealingly clamped about its outer periphery to the valve body and is also clamped about its inner periphery at a location spaced outwardly of the weld to prevent the weld from being subjected to flexure stresses during valve actuation. The outer periphery of the diaphragm (36 min ) may be welded to the valve body (10 min ) outwardly of the outer clamp. The actuating assembly (20) is arranged to produce non-rotary, reciprocatory movement of the operating stem (34) through a bonnet mounted rotary actuator (116). A stem tip seal (16) comprises a metallic seal ring (152) backed by a PTFE ring (158) and surrounded by a harder plastics ring (160) held captive by a sleeve (166).

Abstract: 775,140. Echo-sounding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 4, 1955 [Jan. 3, 1955], No. 48/55. Class 118 (2). [Also in Group XXXIX] An echo sounder of the kind in which a magnetostrictive transducer is energized by pulses consisting of trains of undamped oscillations comprises means whereby said transducer is polarized by pulses of direct current derived by rectifying oscillations from the source providing said undamped oscillations. In the Figure the winding 3 of a magnetostrictive transducer (not otherwise shown) is fed from a source 1 of undamped ultrasonic oscillations, e.g. a pulsed valve oscillator. Each pulse may be substantially rectangular of about two milliseconds duration at 15,000 c/s. and providing a power of 1000 watts. The usual tuning condenser 4 is connected across the transducer. A step-down transformer 6 (e.g. of 15: 1 turns ratio) supplies a bridge rectifier the D.C. output of which is fed to the winding 3 via a choke 7. A blocking condenser 8 is connected as shown, and condensers 9 and 10 may be provided respectively to tune the choke 7 and by-pass the rectifiers. Suggested values for the choke and condensers are given. If the transducer is provided with a separate polarizing winding the rectifier bridge feeds this (as in Fig. 3, not shown) and the blocking condenser 8 is omitted.

Inventor: VINER JOHN CHARLES
IPC: G06Q20/34
Filed: 1999-12-17
Abstract: A payment process and system using a smart card (1) which accesses a remote account at a card issuer (20) via an acquirer (18). The card is read in a terminal (6) which is in two-way communication (17) with the acquirer (18). As part of the payment process, a cryptogram of the transaction data is made by the smart card and used in the terminal (6) as a key to encrypt the PIN, entered by the cardholder, for transmission to the acquirer (18). The acquirer also creates a cryptogram, using the transaction data sent to it by the terminal (6), and uses this cryptogram (which should be the same as that created by the smart card) to decrypt the encrypted PIN. In this way, the use of an expensive tamper-resistant encrypting PIN pad at the terminal (6) is avoided, whilst maintaining security.

IPC: B23B29/04
Filed: 1995-07-27
Abstract: In a tool having a holding element 1 with, for example, hard metal cutting edges 3, 5, the novelty resides in the fact a) that the holding element 1 has vibration-damping characteristics, and b) that the said cutting edges 3, 5 are fitted and aligned in relation to the holding element 1 so that the tool comprising the cutting edges 3, 5 and the holding element 1 would exhibit instability in operation, if the holding element 1 did not have the said vibration damping characteristics. The vibration damping characteristics thereby allow the cutting edges 3, 5 to be fitted in a way which would otherwise result in instability and resultant working marks on the work piece, but which permits faster working speeds measured in terms of the amount of material removed per unit time. <IMAGE>

IPC: B65D88/62
Filed: 1963-01-01
Abstract: 960,561. Discharging material from vehicles; pneumatic conveyers; hoppers. GRANUFLOW EQUIPMENT Ltd. Jan. 1, 1963 [Jan. 2, 1962], No. 134/63. Headings B8A, B8E and B8S. Fluidizing mechanism for unloading containers usually mounted on vehicles comprises a strip 11 with gas-distributing ducts 14 extending longitudinally of a container from a discharge port 5 and a lining 1 secured by a gas-tight seal to the container preferably around a horizontal plane. The strip and duct 11, 14 may be hinged at 10 to the port 5 and rest on the lining or be secured to it. The lining has a gas-tight sealed connection to the port 5. The container is filled through hatches 16 and the lining is of sufficient size to be forced into contact with the container sides when full. To unload the port valve is opened and the material discharges by gravity through a hose 6 until it clogs when gas is supplied through a hose 15 first to the strip 11 and subsequently between the container and lining to cause it to billow outwards first to cause material to fall on to the strip 11 and then when latches are released to raise the strip to the inclined position shown in chain lines. The upward movement of the strip 11 is limited by chains 13. Ducts also supply gas to fluidizing portions of the port 5. In modifications differently shaped and connected linings are provided and in one example an additional under lining attached to the container adjacent the strip 11 and at a line spaced therefrom is used to cause billowing before inflation of an upper lining attached to the strip 11 raises it to an inclined position.

Abstract: 156,263. Compagnie du Chemin de Fer de Paris Ó Orleans. Aug. 30, 1917, [Convention date]. Controlling by high-freyuency current in power conductors.-In electric trains with both front and rear locomotives, which require to be managed from either end, the usual train wires are dispensed with, and in their place alternatively high-frequency current is superposed upon the main power conductors. According to one arrangement, alternator armatures A' to A<4> furnish different high-frequency currents through an inductance K, a condenser CT, and the main power conductors to a corresponding group of resonant receiving circuits R<1> to R<4>, which either indicate transmitted orders or actuate relays for controlling the train motors. Vacuum tube valve apparatus may replace the alternators. The Specification as open to inspection under Sect. 91 (3) (a) states that the control currents may be carried by insulated sectional track-conductors. This subject-matter does not appear in the Specification as accepted.

Filed: 1973-01-03
Abstract: 1375342 Pressure proportioning valves NISSAN MOTOR CO Ltd 3 Jan 1973 [13 Jan 1972] 416/73 Heading F2F In a dual hydraulic braking system a pressure proportioning valve 28 responsive to vehicle load is located between a tandem master cylinder and rear wheel brake cylinders the valve having two inlets 34, 30 fed with fluid from the respective section 10a or 10b of the master cylinder, and an outlet 32 whereby when the pressure at the inlet 34 exceeds a critical value the rate of increase at the outlet 32 varies. On depression of a brake pedal 12 fluid is passed to front wheel cylinders and to the two inlets 34, 30. Below the critical value the combined upwardly acting forces comprising the pressure at inlet 30 and the force F proportional to the vehicle load acting on a differential plunger 88 maintain a shoulder 108 of the plunger 88 in contact with a corresponding shoulder 110 in the valve housing 40 so that full flow is permitted between inlet 30 and outlet 32 by way of a chamber 42, valve seat 106 and a bore 56 provided in a fitting 54. Upon attaining the critical value the pressure at inlet 34 which acts via an opening 202 and chamber 44 on the upper stem portion 98 of plunger 88 moves the latter downwardly whereby a valve head 102 thereof is seated on valve seat 106 to prevent communication between inlet 30 and outlet 32. Thereafter the pressure is modulated through the valve seat 106 as the brake pedal is depressed. The critical value is determined by the cross-sections A 1 , A 2 , A 3  of the plunger and the load force F. The latter is transmitted by an L-shaped lever 264 which has a protuberance 270 acting on the enlarged end 91 of plunger 88. A clockwise bias is transmitted to the lever by a spring 262 attached to one arm portion 264a thereof and an anti-clockwise by a spring 272 coupled via a bracket 278 to an axle cover 276. If the load carried by the vehicle increases the clearance between the axle and the vehicle body decreases thereby contracting the spring 272 to rotate the lever thereby applying a larger force F to plunger 88 and increasing the critical value. In the embodiment shown valve seat 106 has protuberances which allow the passage around the seat.

Abstract: 523,581. Refractory substances. BASIC DOLOMITE, Inc. Jan. 7, 1939, No. 588. Convention date, Jan..15, 1938. [Class 22] A refractory substance is formed by firing a mixture providing magnesia, lime and silica in proportions to yield periclase, and merwinite, adding lime to the fired material and again firing. The merwinite is changed, at least in part, into calcium orthosilicate. Raw materials for supplying lime and magnesia are magnesite, brucite, limestone, magnesian limestone, and dolomite, and for supplying silica are quartz, tripoli, magnesium silicates, such as dunite, sepiolite, saponite, talc, magnesian bentonites or clays and sedementary magnesites. Small quantities of borates, phosphates or chromium oxide may be added. The raw materials are ground and fired at 2,800-3,000‹F. The clinker is mixed with lime in the form of hydrated lime, limestone, dolomite, or a high calcium clinker, preferably to raise the limesilica ratio to 1.85 to 1. The pulverized clinker and lime are mixed with water, pressed to shape and fired at 2,600‹F.

Abstract: 673,648. Gasifying powdered carbonaceous material. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. Jan. 8, 1949 (Jan. 8, 1948], No. 608/49. Class 55 (i). In gasifying fire-grained coal, coke, coal slime, sawdust, &c., preheated to about the gasification temperature, gases at a higher temperature, comprising mainly carbon dioxide and steam are introduced into the bottom of a zone with boundaries diverging upwardly into which the fuel is admitted in concurrent or counter-current flow, the velocity of the com. bustion gas at the inlet being adjusted to be less than that required to keep the larger fuel particles in suspension but to be sufficient, though progressively falling off, to carry the finest particles upwardly until gasification is completed. Fuel of grain size up to 10mm. passes from an electrically-heated dryer 3 into a preheater 9 supplied with products from a combustion chamber 5 in which gas from pipe 8 is burnt with air or oxygen, steam or carbon dioxide being added. Products from a chamber 11 similarly supplied with gases enter the base of a conical producer 10 and mix with the stream from the preheater in a throat 10a. Fuel and gases may also be introduced through inlets 15, 16, water spray at points 17 and catalysts at 18. The product gases pass through a separator 21, heat exchanger 24, and gas turbine 26. A series of superposed horizontal plates may be mounted in the lower part of the producer which is waisted between each pair of plates the effect being to cause larger particles to disintegrate, and inlets preferably at the narrowed portions may introduce fuel and gases radially or tangentially upwardly or downwardly. In another arrangement the fuel is admitted at the top. Part of the gases generated may be taken off at one or more points and returned to a preheating combustion chamber and the heat of the remainder recovered in heat-exchangers. A second producer may be employed from which molten clinker is removed. The CO : H 2  ratio in the final gas which may be 1 : 1 if oxygen is initially employed, may be adjusted by introducing steam or water into the producer at one or more points, together with catalysts facilitating the conversion to carbon dioxide and hydrogen. Further formation may similarly be increased. Gasification may be effected under superatmospheric pressure, e.g. 3 atmospheres, and the gas supply to producer and preheating combustion chamber , caused to pulsate.

Electrode 32 is normally held slightly positive and the transfer electrodes more positive (Fig. 5, not shown): to inject a discharge the input electrode is pulsed more positive and either A or C bus is grounded according to the direction of movement required: the narrow discharge, e.g. as a pointer (Fig. 6, not shown), may be moved by grounding each bus in turn while the others are restored to positive. If the input electrode is grounded in its turn as D the discharge may be moved past it in continuous rotation, or if a transfer pulse to move it beyond is not provided the discharge will be erased. "Hold" at a fixed location may be provided, e.g. by CBA-BCDCBA cycles, and by successive input pulses an arc may be filled in (Fig. 7, not shown). For display at least one face and its electrodes should be transparent. In an alternative embodiment two nearly opposed uninsulated input electrodes are provided, substituting, e.g. for A and B transfer electrodes; to initiate a discharge the input electrode nearest to the transfer electrodes in the desired direction of rotation is activated (Figs. 8, 9, not shown).
