Abstract: PROCÉDÉ DE PRÉPARATION D’UN MATÉRIAU EN CARBONE DUR À HAUTE PERFORMANCE ET SON UTILISATION La présente demande divulgue un procédé de préparation d’un matériau en carbone dur à haute performance et son utilisation. L’amidon, le phosphate et l’eau sont mélangés pour l’imprégnation, et le matériau imprégné est séché pour obtenir de l’amidon post-imprégné, et l’amidon post-imprégné est soumis à un traitement thermique sous atmosphère inerte pour obtenir des microsphères de carbone à base d’amidon, et un gaz mixte de dioxyde de carbone et d’un gaz inerte est introduit dans les microsphères de carbone à base d’amidon pour la réaction de carbonisation afin d’obtenir le matériau en carbone dur. Dans la présente demande, l’amidon et le phosphate sont mélangés pour une réaction de réticulation, et le matériau est dopé N en introduisant un groupe amino, et soumis à une réaction de carbonisation après que l’amidon et le phosphate subissent une réaction de réticulation. La matière première est maintenue sphérique ronde pendant tout le processus, ce qui permet d’éviter le problème de carbonisation directe pour produire du carbone grumeleux mousseux, évitant ainsi l’augmentation du film SEI et donc la diminution de la capacité spécifique et du rendement initial.

Title: Wax removal from mould of lost wax casting machine - by irradiation after introduction of matl. with high loss factor
IPC: B22C9/04
Filed: 1974-08-09
Abstract: The wax is molten and removed from the precision mould of a lost wax casting machine by introducing into the structure of the mould a material with a high loss factor (over 1, 0) in the frequency range from 300 to 30,000 MNz (900-2500 MHz). The preferred material is graphite or carbon in the form of a coating. The mould is then irradiated by microwaves of this range until the wax has become liquefied. This is less expensive than using solvents and releases no toxic fumes. It is easier to operate and to include in a flow line production than wet steam heating in an autoclave. The wax is molten on the surface before thermal elongation can crack the ceramic shell. The process is automatic and continuous.

Title: Telephone handset with handgrips surface increased by holes - shaped to absorb and scatter sound waves to reduce feedback
IPC: H04M1/20
Filed: 1974-12-20
Abstract: The telephone handset has the surface area of its handgrip increased to reduce the effects of acoustic feedback. This surface between the microphone and loudspeaker cups is shaped according to geometric laws of reflection so that the sound waves are absorbed or scattered and thereby reduced in intensity. The increase in area is achieved by boring holes in the handgrip. The holes may have cylindrical or tapering walls. The sound is scattered by irregular inclined surfaces on the handset. The holes act as absorbers and the irregular inclined surfaces as scattering regions.

Title: Method of mfg. brake or clutch friction linings - uses electrostatic powder application combined with thermal bonding
IPC: F16D69/02
Filed: 1975-02-07
Abstract: Very thin (10-4 to 10-6m.) and hard wearing friction linings are applied to brake shoes or clutch plates. Powder mixtures of various components are coated by electrostatic methods on to the supporting substrate. Bonding to the substrate is achieved by the application of head and both the coating and bonding may be performed as a continuous process and almost simultaneously, thus reducing production costs. The lining materials envisaged have a substantial metallic content and in order to allow the electrostatic coating method to be used, the metal particles are either coated with an insulating material which is voltatilised or forms an additional component of the lining during the heat treatment, or inorganic metallic compounds are used which are reduced to the metallic form during heat treatment.
