Patent GB-2195727-A (GB)
Title: Petroleum equipment tubular connection
Inventor: FAIREY COLIN B
IPC: E21B17/042
Filed: 1987-08-05
Abstract: An anaerobic sealant composition is employed to seal a pipe joint between threaded pin and box members intended for use in petroleum drilling operations. The composition is applied to one or both of the members. The members are then joined and the composition cured into a solid form which bonds to the members and fills the space between them. The constituents of the composition can be selectively varied to control its lubricity which also affects the make up torque. Additionally, the concentration of the sealant composition can be selectively varied to control the break out torque of the joint to which it is applied, and preferably make the break out torque substantially greater than the make up torque. Excellent seals can be obtained using lower grade pipe, and the pin and box members can be made up with the application of lower torque to the assembly without reducing the sealing capability of the connection. The preferred composition also serves as a rust and corrosion inhibitor for the joint. <IMAGE>

Patent GB-2230843-A (GB)
Title: Anaesthetic apparatus
Inventor: ROUSSOS EVANGELOS
IPC: A61M16/10
Filed: 1990-04-12
Abstract: The mixture of nitrous oxide and oxygen in an anaesthetic apparatus is controlled so that the oxygen percentage does not fall below approximately 25% by a lever 58 simultaneously actuating slide needle valve 66 of oxygen valve 32 and slide needle valve 68 of nitrous oxide valve 34. Thus the oxygen control knob 36 has to be operated whenever a nitrous oxide/ oxygen mixture is required. Nitrous oxide adjusting knob 38 can be used in co-operation with a further lever 60 to lower the percentage of nitrous oxide in the mixture below the nominal predetermined value. This nominal value is determined by the ratio of the lengths of the point of activation of respective valves 32 and 34 from the hinge 62 of lever 58. Rotational adjustment of knob 36 is conveyed to lever 58 by ball bearing 54 which in turn conveys this motion via ball bearing 84 into translational motion of needle tip 74 with respect to needle seat 70 against the action of basing spring 80. An air supply valve 110 may also be provided. In Fig 3 (not shown) the adjacent ends of the levers 58 and 60 have engaging stepped extensions. <IMAGE>
