Title: Polycrystalline diamond prodn. from diamond powder - at very high temp. and press. using diamond grains of different size and additives
IPC: B01J3/06
Filed: 1974-01-07
Abstract: Polycrystalline diamond prodn. by applying high pressure to diamond powder at high temps. is improved in that the temp. is 2700-3700 degrees C (pref. 3100-3700 degrees C) and the pressure is equal to that at which graphite is converted into diamond, i.e. 120,000-170,000 atm. Alkaline earth cpds. can be added. Diamond grains of different size are mixed together. The application of higher press. and temp. compared with the known methods of producing polycrystalline diamonds improves the mechanical strength of the products, which are suitable for use in drilling tools. The wearing resistance is increased by the alkaline earth additions and by the use of diamond grains having different size. The pref. additives are fluorspar, limestone, chalk and talc; they are pref. applied in layers below and above the diamond powder layer. Pref. two diamond powder fractions are used having the size of 0.1-2.0 mu and 5-60 mu respectively; these fractions are used in a weight ratio of 20-80:80-20, pref. 50:50.

Title: Window or shutter fastener - has screw jack mechanism converting rod rotation into axial displacement
IPC: E05C9/08
Filed: 1974-01-08
Abstract: A vertical rod (13) has projecting stub locking bars (20) to lock the side of a hinging leaf to the casing or adjacent leaf and the sill (10) by axial rod displacement.

Title: Enclosed thermal current interrupter - has three levers pivotally mounted in housing and positioned by manual actuator
IPC: H01H73/30
Filed: 1975-06-02
Abstract: In the interrupter housing is a thermally responsive element which bends under excessive current to enable the moving contact set to shift into a rest position. In the housing are mounted three levers, one of which is spring-loaded in dependence of the position of the manual actuator. The third lever carries the moving contact set and its end shape permits engagement of a holding edge. The other lever end is hinged to the second lever end, whose second end is effectively hinged to the other end of the first lever. The holding edge position depends on the thermally responsive element to bring the moving cantact set into its operating position. In cooperation with the lever system the moving contact set slides into its rest position.

Title: Domestic or industrial building heater - effecting mechanical operations necessary for thermodynamic cycle almost reversibly, with high efficiency
Inventor: TUBEUF JEAN
IPC: F28D15/02
Filed: 1975-11-28
Abstract: An installation for heating buildings used as dwellings or industrially makes use of a gas which is in contact alternately with a cold source and a hot source by means of inlet and outlet heat exchangers and a compressor which circulates the gas. The gas describes a thermodynamic cycle in a closed circuit. The exchangers connects points of the circuit situated at different heights in a natural or artificial gravity field. The gas has a lower specific heat capacity than the air and undergoes substantially isothermal press. changes. It exchanges heat with a liquefiable fluid of high latent heat. Typically, the gas is argon and the fluid is pentane. The installation operates in a cycle which approaches closely thermodynamic reversibility. It is simpler and is more efficient than existing installations using a fluid which changes its physical state, and rotary machines, in several stages, of low efficiency because of thermodynamic irreversibility.

Title: Hydrogen sulphide removal from gases - by reaction with sulphur dioxide in a solvent for sulphur
IPC: B01D53/52
Filed: 1975-12-22
Abstract: Removal of H2S from gases is effected by reacting the H2S with SO2 in a solvent for sulphur, and sepg. the purified gas from the S soln. The S is then sepd. from the solvent, which is recycled. The solvent is pref. a phenol, esp. m-cresol. The process is pref. carried out by absorbing the H2S (or SO2) in the solvent at 15-80 degrees C and 1-150 (esp. 5-80) bars, and then contacting the soln. with SO2 (or the gas) at 80-180 degrees C (esp. 112-150 degrees C) and 1-150 (esp. 5-80) bars. The process is esp. useful for purifying natural gas and refinery off-gases (e.g. from desulphurisation or catalytic cricking units). The process gives purified gases contg. 0.1% H2S. The S isolated is not contaminated with carbon when the feed gas contains hydrocarbons (cf. the Claus process).
