Title: Decorative foil mouldings with injection moulded support - reducing tool costs and cycle times compared with plaster backed mouldings
IPC: B29C45/14
Filed: 1973-10-15
Abstract: Three dimensional foil mouldings made by bridging the daylight of an injection mould cavity with a sheet of thin foil.

Title: Catalytic gas radiator safety system - has thermocouple monitoring temp. and atmosphere controller with flame impinging on copper sheet
IPC: F23N5/10
Filed: 1975-02-07
Abstract: The catalytic radiator has a safety system which ensures that the gas supply is cut off when the combustion products are excessive or when the panel temperature is too low for complete combustion.

Title: Contacting liquids with particulate solid - in a method which operates continuously and countercurrently and incorporates solid regeneration stage
IPC: B01J47/10
Filed: 1975-09-03
Abstract: An appts. for contacting a liq. with a particulate solid, in continuous countercurrent operation, incorporates two vessels. A liq. to be treated by the solid circulates through the first vessel and a liq. for regenerating the particulate solid circulates through the second. There may be a third vessel in which the regenerated solid is further treated. The vessels contain a central axially placed tube. The liq. flows upwards and the solid downwards in the annular space outside this tube. The solid is entrained in a jet at the bottom of each vessel so that it is forced upwards inside the central tube and is recovered in a receiver at the top of the tube. From there it is charged to the top of the annular space. The appts, may be used for demineralising liquids by ion-exchange resins, purificn. of domestic or industrial water by activated carbon, filtration through granular material, percolation through absorbent material, chemical reactions. Continuous transfer of solid particulate material may be obtd from a zone where it is charged or exhausted to a zone where it is regenerated, so that the first zone operates at a max. and constant yield. the method is simple, convenient and economical.

Title: Multi-mill installation to extract juice from sugar cane - improves extn. rate by preventing aeration of pulp between mills
Inventor: HUGOT EMILE
IPC: C13B10/04
Filed: 1976-05-05
Abstract: Extn. of juice from sugar cane comprises a wet milling process. The installation uses several mills in series through which cane pulp is passed. Between each pair of mills the pulp is passed through a soaking tank to take water/juice liquor before the next milling operation. The discharge roll of each mill but the last now delivers pulp directly into soaking liquor without. Exposing the pump to air. The liq. at the discharge roll of each mill is, pref. mainly composed of juice extracted by the inert mill but one downstream, supplemented by juice from the next mill downstream. The liq. at the discharge roll of the penultimate mill is mainly make-up water supplemented by juice extracted in the final mill. Juice for subsequent processing is derived from the first two mills of the series. All mills but the first pref. comprise a fourth main roll feeding pulp into the conventional, three-roll arrangement and opposed by the conventional, small packing roller. Extracting juice from sugar cane by milling. Since cane pulp is no longer exposed to the air between mills, air does not become trapped between pulp fibres and impede the dissolution of sugar. This results in an improved extraction rate.
