Title: Press tool for moulding thermoplastic record discs - incorporating a sintered filter to develop symmetrical heat transfer fluid flow
IPC: B29C43/12
Filed: 1974-11-21
Abstract: Press tool where one face of a shallow cavity comprises a thin diaphragm backed by an annual recess allowing radial circulation of a temp. controlled hydraulic fluid, where the fluid is admitted into a chamber concentris with the drain and has to pass through a porous baffle with generates an impedance or back pressure on the fluid flow. Esp. for moulding impressions into thermoplastic blanks of a recorded signal profile on the exposed face of the diaphragm via for reproducing video record discs. The impedance smooths the distribution of fluid flow from an offset entry to obtain a uniform radial distribution of the fluid towards the annual passage feeding inward radial circulation behind the diaphragm, thus ensuring symmetrical pressure and temp. distribution to the tool face.

Title: Insulation of cavity walls with granular material - by simultaneously injecting material and removing air to avoid pressure build-up
IPC: E04B1/76
Filed: 1974-11-06
Abstract: The process consists basically in sucking out air from the cavity simultaneously with the injection of the insulating material. The apparatus consists of a chassis (1) with the wheels (2) on which is a tank (3) containing approximately 100 litres of the insulating material.

Title: Shaped silicon nitride body prodn - by forming body from silicon and (inter)metallic phase dissolving the latter and nitriding silicon
IPC: C04B35/591
Filed: 1974-12-24
Abstract: Shaped silicon nitride body is produced by first forming (by metallurgised methods; pref. by casting) a starting body contg. 40-98 wt.% Si, the balance being a metallic and/or intermetallic phase (pref. Al, also Cu, Ag, Zn, Sn and/or silicide of Li, Ng, K, Sr or Ba); then etching away (e.g. with HCl) the metallic or intermetallic phase; and nitriding the remaining Si skeleton by known methods. The starting body can be linked with another body to produce a composite e.g. a mtallic or nonmetallic body coated with Si3N4. Complex Si3N4 bodies are produced. This method is simpler and cheaper than the known processes. Good mechanical strength is achieved. The porosity of the prod. can be varied as desired by altering the Si content of the starting body.

Title: Estimating molar mass of fluid - by comparing signals from fluidic oscillator fed with reference and test fluids
Inventor: MANTOUX GERARD
IPC: G01N33/00
Filed: 1975-11-04
Abstract: Feeding a gas under press. to a fluidic oscillator gives a press. oscillation at a frequency proportional to a first approximation to the velocity of sound in the gas. For a given oscillator, the frequency varies with the temp., the molr mass of the gas, the ratio of the specific heats of the gas, and the pressure of feeding the oscillator. A reference fluid of known molar mass and the fluid of unknown molar mass are fed successively at constant pressure and temp. to a fluidic oscillator. The signals produced are received and processed to obtain a measure which is compared to a standard. The utilisation of a single fluidic oscillator fed successively by the two fluids makes the process independent of temp. and pressure and responsive only to the nature of the gas. The appts. receiving the signals can be of ordinary quality, as the only useful information is the frequency of oscillation of the fluidic oscillator.

Title: Cageless ball bearing taking axial and radial loads - has step in shaft and housing dias. giving track for balls which are held by end rings
Inventor: AUTRET MARCEL
IPC: F16C19/16

Title: Metal scrap block extrusion - through press die after applying vacuum to block in receiver under pre-load
IPC: B22F8/00
Filed: 1976-01-27
Abstract: Blocks formed from metal scrap are extruded through the die of an extrusion press by introducing the block in the block receiver of the extrusion press. Before the scrap is extruded by the pressure of the main extrusion press cylinder through the die, all air is evacuated from the block in the receiver. This is done by isolating the block in the receiver and applying a vacuum to it, preferably accompanied by an additional compacting force. This eliminates the appearance of air bubbles or air inclusions in the extruded product or on its surface. The extrusions therefore have a much higher quality.

Title: Enriching red wine colour with extracts from pressed marc - by mixing marc with and soaking in fresh must
IPC: C12G1/02
Filed: 1976-04-09
Abstract: The pressed marc is mixed with and soaked in fresh must until the must extracts a controlled amt. of colour and tannins from the marc. The wet, spent marc is then drained and finally pressed to recover all the must. Coloure extraction is pref. controlled automatically by recirculating must through the marc until a colour detector senses a satisfactory colour and redirects the flow of must to a prod. outlet. During colour extraction, the must soaks through the marc and is then recirculated via a fixed head balance tank which receives must from the post-extraction drainage operation and also has a fresh must make-up supply. The colour detector pref. actuates one only of two pumps at any time; one pump recirculates for further extraction while the other pumps away adequately enriched must to prod. discharge. The more attractive wines are obtd. by increasing the extraction from pre-pressed marc. The process is made automatic to handle industrial scale production.
