Abstract: This invention relates to a method for the oxidative conversion of methane to ethylene and/or ethane and to a catalyst system for use in the method.In more detail a method for the oxidative conversion of methane to ethylene and/or ethane in which a mixture comprising methane and oxygen is heated to a temperature of from 500.degree. to 1000.degree. C. and the heated mixture is contacted with a catalyst system which comprises a first component which is a non-reducible metal compound and which first component is sufficiently refractory to withstand the operative temperature and a second component which is one or more oxycompounds of boron or phosphorus provided on the surface of the first component.

Abstract: A catalytic process for the generation of hydrogen by the partial oxidation of hydrocarbons, especially alkanes such as methane or hexane. The preferred catalyst system comprises from 0.01 to 5 wt % platinum and from 1 to 15 wt % chromium oxide supported on a refractory solid such as silica. Also a reactor for effecting the process in which the reactants are injected into or among the catalyst system and a technique for starting the process at ambient temperature by introducing an initiating compound such as methanol into the catalyst system.

Abstract: An improved body member for a shuttle returner used in a projectile loom. Embedded within the relatively elastic body member is a relatively inelastic reinforcing element which takes up tensile force applied to the body member, thereby strengthening the body member. The reinforcing element is substantially flexible in response to compressive force applied to the body member, so that the elasticity of the body member in compression is not reduced by inclusion of the reinforcing element.

Abstract: An exercise machine in the nature of a stationary cycle exerciser. The exercise machine replaces the conventional crank-arm rotary pedal drive with reciprocating treadles or pedals connected to drive a work-utilizing device at a substantially uniform rate throughout the entire input stroke by the user. Hand-operated levers are also provided for manipulation by the user, and movement of these levers is coupled to the working load.

Abstract: An electrical connector having a plurality of terminals in an insulative housing includes an improved locking and shunting assembly. This improved locking and shunting assembly can be inserted into the housing of the electrical connector from the mating face to both lock terminals in position and to shunt or common adjacent terminals. Each shunt comprises a resilient terminal which is attached to an insulative locking member by simply sliding the terminal across one surface of the locking member to establish locking engagement between the stamped and formed shunt and the insulative locking member at both ends of the shunt.

Abstract: A catalytic hydrogen generator which generates hydrogen by the partial oxidation of methanol by oxygen (usually supplied as air) which comprises a gas permeable catalyst system having an upstream zone (2) filled with a copper catalyst supported on a refractory support (3) (for example silica or silicate granules) and a downstream zone (4) filled with a mixture of a similar supported copper catalyst and a platinum or palladium catalyst supported on a similar refractory support (5b). A mixture of methanol and oxygen is fed to the upstream zone and initially permeates through to the downstream zone where spontaneous oxidation of the methanol is initiated raising the temperature of the system to a level at which partial oxidation of methanol in the presence of the copper catalyst in the upstream zone (2) commences and produces hydrogen.

Abstract: An improved shuttle returner for use in projectile looms. The shuttle returner comprises a relatively inelastic member for receiving the impact of an arriving shuttle, and a relatively elastic member coupled to the receiving member for absorbing the shuttle impact. The receiving member and elastic body member are joined together along mutually confronting surfaces substantially perpendicular to the line of impact, maximizing transfer of force into the body member without transmitting substantial impact through the elements interconnecting the receiving member and body member.

Abstract: A high density, zero-insertion-force electrical circuit board connector is provided comprising an insulator body having walls defined in part by reciprocally movable cams. Contacts with offset terminal portions are arranged in close-packed array and are simultaneously cammed into the closed position by cam followers mounted in a reinforced insulator housing.

Abstract: A process for the hydrogenation of an unsaturated organic compound in emulsion comprises contacting the emulsion with gaseous or dissolved hydrogen in the prescence of a hydrogenation catalyst in solution.

Abstract: A colored inorganic complex of titanium, stannous and zinc oxides for use in making pigments capable of imparting for example red, yellow or green colors to plastics, paints, glasses or ceramics without reliance on toxic moieties. A wider range of colors can be obtained if the complex is used in a pigment system comprising excess oxides of titanium and zinc or stannic tin. The complex is preferably made by adding an acidified aqueous solution of ions of the metals (e.g. as metal sulphates or metal halides) to alkali so as to precipitate the oxides or oxide precursor such as hydrated oxides which are then washed and fired at over 450.degree. C. to form the complex. The colors obtained may be adjusted by the presence of traces of residual alkali metal moiety.

The L-shaped supports are used to pivot the trampoline from a generally horizontal position or plane to a substantially vertical position or plane.
