Title: Internal combustion opposed-piston barrel engine
Inventor: FAIRNEY WILLIAM
IPC: F01B3/04
Filed: 2007-09-26
Abstract: An i.c. engine, preferably diesel, has at least two cylinders 10 and a drive shaft 11, each cylinder having two opposed pistons 13 therein, with piston heads 13a, 13b facing each other and piston rods of the pistons coupled to the drive shaft through respective opposed cams 12a, 12b. The opposed cams 12a, 12b are profiled such as to ensure that the motion of the pistons 13 in one cylinder at and near Bottom-Dead-Centre (BDC) is balanced by the motions of the pistons 13 in another cylinder at and near Top-Dead-Centre (TDC), thus ensuring that piston inertia forces are balanced out thereby reducing vibration and noise. Furthermore the profiles of the cams 12a, 12b at and near Top-Dead-Centre are such that whilst the opposed pistons 13 are held together at a fixed separation until combustion is substantially complete they continue to move along the cylinder bore thereby eliminating dead motion and the associated breakdown of lubrication which can lead to wear and overheating.

Title: Communication indicating a security level
Inventor: STRUIK MARINUS
IPC: H04L9/00
Filed: 2004-08-19
Abstract: In a secure communication system, an adaptable security level is synchronised between devices by inserting security bits (35-37, fig. 3) into the control bits of a message frame or header (32) which indicate the selected security level (eg.0, 32, 64 or 128 bits) and whether encryption is aimed on or off, thus allowing modification on a frame-by-frame basis. For multiple recipients, a minimum integrity level common to all of them can be selected. The security bits may also indicate parameters in an algorithm. Communication is organised by a network stack (Fig. 6) which passes payloads [m] and security levels (SEC) between various layers (application, network, MAC, physical etc.) and encryption keys K. Security level information may also be passed via acknowledgement (ACK) messages over a feedback channel.

Title: Correction for borehole casing attenuation in electromagnetic induction surveying
Inventor: GAO GUOZHONG
IPC: G01V3/28
Filed: 2009-09-23
Abstract: Methods and related systems are described for determining the casing attenuation factor of a metallic borehole casing while performing electromagnetic induction surveying of a formation surrounding the borehole 310, 312. The method includes deploying an electromagnetic transmitter 330 into a section of the borehole and making impedance measurements at a first frequency. The impedance measurements are then compared with predetermined relationships between a casing correction factor and the product of parameters relating to casing conductivity, casing thickness and electromagnetic frequency or a relationship between a casing correction factor and a parameter relating to the impedance measurement. This method works well for non magnetic casings such as Chromium casings. The attenuation due to the casing is compensated for at all frequencies while the surveying of the formation is being performed.

Title: Method of making machine belts
IPC: F16G1/28
Filed: 1958-03-28
Abstract: 890,788. Making machine belts. PIRELLI S.p.a. March 28, 1958, [May 11, 1957], No. 10077/58. Class 87(2). [Also in Group VIII] A machine belt is made by forming, e.g., on a mandrel, a cylindrical support layer by solidifying and hardening a liquid elastomer to a point at which it will not harden further, laying on the support a reinforcing layer or a number of such layers interspersed with intermediate elastomeric layers, and applying a covering layer of liquid elastomer which is subsequently solidified and hardened. The various elastomeric layers may be of the same or of different materials, for example of differing degrees of hardness. The elastomers used may be natural or synthetic, and may comprise a polyamine, polysulphide, polyvinyl chloride base resin, a polyester, or a polyurethane derived from an ester or ether, preferably a condensation product of naphthalene diisocyanate and glycol adipate. The cylindrical support layer may be east in an annular mould and transferred to the mandrel, or may be spread on the mandrel itself from a trough with the aid of a doctor blade. The reinforcement may comprise filaments or strips, of metal, textile material, or a metal-textile mixture, which may be wound on helically, Fig. 5, or may be a fabric. The outer surface of the support layer may be roughened, e.g., by grinding on the mandrel with a traversed grinding wheel, or by etching, for example with dimethyl formamide, before applying subsequent layers. The completed laminate, removed from the mandrel, may be used as such or divided into narrower belts by cutting in planes normal to the axis. Fig. 7 shows a belt having a support layer 1, moulded with teeth and of hard material, a reinforcing layer 9, and an outer layer 10 of softer material. If teeth are required on the outside, a belt, similarly made but of soft and hard materials respectively, may be turned inside out.

Title: Improvements in readily connectible and disconnectible spigot and socket couplings
Inventor: HARRIS FRANK ERIC
IPC: F16L37/086
Filed: 1961-03-22
Abstract: 939,356. Pipe couplings. BRITISH SYPHON CO. Ltd. Feb. 12, 1962 [March 22, 1961], No. 10469/61. Class 99(1). In a readily connectible and disconnectible spigot and socket coupling of the type having key means retractably projectible through one or more openings in the socket wall to key into the spigot, there is an external spring-influenced control sleeve 19 axially slidable on the socket 4 and the key means incorporates two diametrically opposed key members 23 which extend across the interior of the control sleeve in the manner of chords and are pivotally connected thereto so as to swing between an operative projecting position to a retracted inoperative position. in response to relative axial movement between the sleeve and socket. As shown, the control sleeve 19 encloses a spring 18 between rings 16, 17 and carries two key members constituted by straight lengths of wire 23 forming chords across the sleeve and projecting through slots 24 in the sleeve, the returned ends 23a of the wires being pivotally engaged in holes 25 in the sleeve. The pivot axes of the wires are substantially coplanar with diametrically opposed slots 22 formed in the socket. In connecting the parts of the coupling, the sleeve is gripped to urge the socket over the spigot by a unidirectional push applied to the sleeve so that the frusto-conical shoulder 1b of the spigot abuts the wires 23 and cause the latter to swing about the pivot axes thereof and constrain the wires to retract from the socket slots 22. When the spigot is fully home and the sleeve released the latter returns under influence of the spring 18 to an intermediate locking position in which the wires will be fully projected into the spigot slots 22. The spigot and socket incorporate spring- loaded valves 6, 11 which coact to open when the spigot and socket are coupled. The key members may be in the form of pivoted plates or strips.
