Title: Clarification and concn. of fruit and vegetable juices - by ultrafiltration in at least two stages with retained material in molecular wt. range 15000 to 25000
Inventor: VERNIERS CLAUDE
IPC: C08B37/18
Filed: 1980-08-13
Abstract: Process is described for clarifying juice which has been extracted from fruit or vegetables by pressing. The process is of the type in which the expressed juice is passed through an ultrafiltration membrane which gives a primary clarified filtrate and a primary retained material which is passed through a second ultrafiltration membrane which yields a second clarified filtrate and second retained material. At least one of the ultrafiltration membranes is suited to hold retained material with a nominal molecular weight within the range of 15,000-25,000. Pref. the pH value of the expressed juice is determined and the temp. adjusted before clarification to within plus or minus 3 deg.C of (80-6pH) deg.C. At least one stage of ultrafiltration has an inlet pressure between 3 and 5 kg per square cm and an outlet pressure between 1 and 2 kg per square cm. Pref. a secondary filtrate is added to the primary filtrate and the primary retentate is diluted before secondary ultrafiltration. The process is to separate, concentrate or purify solutes in the molecular weight range 15,000-25,000, partic. for the extn. of pectins, starches, proteins, tannins etc. This ultrafiltration process requires less time, labour and energy than previous extn. methods to produce the above prods. No filtration additives are required and the clarified filtrates are sterile without heat treatment. Waste matter is reduced and prod. yield higher than with conventional extn. processes.

Title: Cotton grey goods processing - has combined kier-boiling and mercerisation and combined bleaching-dyeing stages
Inventor: GOTOVTSEVA LJUBOV ALEXEEVNA
IPC: D06B7/08
Filed: 1980-08-29
Abstract: The kier-boiling of the cotton grey goods, formed from ply yarn, is combined with the mercerisation process by an alternate feed of caustic soda soln. and caustic soda vapour with treatment times for the soln. and vapour in a ratio of 1:1. The fabric is tensed at 5-10 kg/m for steaming before steeping in lye in the roll. Steaming is applied after bleaching and dyeing for 1-2 mins. under tension and for 2-10 mins. at no tension. The fabric is spread during kier-boiling and mercerisation, before steaming in the roll and steeping and during steeping in lye. The process increases the mercerising effect and also reduces the equipment size while raising productivity.

Title: Floor construction e.g. for wood block or cement finishing - including loose cork insulation layer
Inventor: RIMPAU JOCHIM
IPC: E04F15/18
Filed: 1980-09-25
Abstract: Floor construction includes a layer of insulating loose bulk material covered with dry boards esp. boards contg. plaster. Specifically the loose bulk material is untreated cork granules of particle size distribution 35 wt.% 0.15-1.00 mm., 65 wt.% 1.00-4.00 mm the latter being split up into one third each in the ranges of 1.00-2.00, 2.00-3.00 and 3.00-4.00 mm. Part of the cork may be replaced by another material esp. perlite granules intimately mixed with the cork; or an organic material in fibre, shell or lamellae structure. Insulating material conserves its density over long periods in spite of considerable surface wear on the boards or tiles due to walking. The construction is temperature insensitive and is particularly suitable for use with electric under floor heating systems. Improved acoustic insulation is achieved, which is lasting.

Title: Reductant metallurgical coke prodn. - by controlled de-volatilisation of shaped briquettes made from coal and binder
IPC: C10B53/08
Filed: 1980-11-14
Abstract: Metallurgical coke for use as a reductant in blast furnaces is produced by (a) prepg. a feed from (i) dry particulate coal capable of coalescing on heating and (ii) an organic binder (I), (b) compacting the mixt. into shaped forms, and (c) heat treating the shaped formed at sequentially increasing temps. such that volatiles expulsion is limited in =0.05% per minute, and specifically such that the temp. is increased at a rate of 10 degrees F per minute during the period when the coal is at a temp. at which it tends to soften. (I) may be pitch derived from the distillation and blowing of coal tar, tar or pitch derived from the processing of the shaped forms, an organic polymer, an organic monomer which polymerises on heating, sugar or a sugar product. No air is introduced into the system at any point and thus autoignition or explosion dampers are eliminated. No special blend of coals is required. A high-strength product is obtained in commonly available, safe equipment.

Title: High voltage DC circuit breaker with electromagnetic arc stretching - uses coil inside tubular fixed contacts to stretch arc forced into contact centres by compressed air blast
Inventor: THURIES EDMOND
IPC: H01H33/14
Filed: 1980-12-16
Abstract: The high voltage direct current circuit breakers are used in high voltage direct current transmission links. A series string of compressed air circuit breakers is used, with voltage grading resistors and capacitors connected over each contact. The circuit breaker has two fixed tubular contacts with a moving sleeve bridging them when the breaker is closed. A solenoid is wound inside each contact, supported round the outside of the coils by an insulating sleeve fixed inside the tubular contact. An electrode attached to the supply buses is provided on the centre axis of each coil and at the end remote from the moving contact. When the breaker opens the arc is forced into the fixed contact centres by a compressed air blast, and the electromagnetic force created by the solenoid extends the arc to the fixed electrodes.

Title: VHF antenna for elimination of jamming - includes receiver to detect jammer direction for modification of antenna phase shift to optimise reception
Inventor: BEGUIN DANIEL EDMOND
IPC: G01S7/28
Filed: 1982-02-05
Abstract: The antenna has a linear system comprising four elements with equal and identical radiation diagrams. The elements are equally spaced and the inner pair are connected to a hybrid junction providing sum and difference signals for receivers. The outer elements are similarly connected to a hybrid circuit and sum and difference receivers. The receiver outputs are sampled to provide the in phase and quadrature components of two vector signals. These values are applied to a memory. The components for the jammer are applied to processor circuits to obtain its direction using the antenna characteristics stored in a second memory. The antenna phase shift is adjusted to optimise target reception in the presence of jamming and the target error is calculated and corrected by a third processor.

Title: Pilot-controlled safety valve - has pilot valve operating in two stages with flow adaptor
Inventor: REIP RAYMOND G
IPC: F16K47/00
Filed: 1982-04-06
Abstract: The pilot-valve-controlled safety valve is for use with pipes and vessels under high pressure. A valve operating in two stages, through which the medium normally does not flow, controls one of considerably greater capacity. Flow-regulation members perform the positive valve function and work with the first stage, and the main valve is pref. mounted directly on the vessel to be protected. A flow adaptor (100) with a self-cleaning opening is mounted between the main chamber (68) of the main valve and ports leading to the pilot valve. A ball (16) is mounted in a selector (24,15) to allow testing of either the pilot valve the complete valve. The pilot valve acts on the main one in proportion to the amount of excess pressure. A partially pressure-balanced valve unit of large dia. and joints of smaller dia. increases sensitivity to excess pressure. A ball-valVe forms a stopcock for testing gas.

Title: Thin amorphous metals prodn. - from molten jet flattened magnetically and super-quenched
Inventor: ETAY JACQUELINE
IPC: B22D11/06
Filed: 1982-04-21
Abstract: A jet of molten metal, dropping more or less vertically is passed through an alternating magnetic field of sufficient intensity and frequency to flatten it to a ribbon of molten metal. If the required thickness of the ribbon is "a" the frequency (f) must be at least the value given in formula (I) where (mu) is the magnetic permeability of the molten metal, and (sigma) its electrical conductivity. The ribbon is cooled suddenly, e.g. by contacting a rotating chilled cylinder, and super-quenched to produce a strip of solid metal with an amorphous structure. This method of flattening a jet by magnetic means is preferable to running molten metal through a narrow slit, which is susceptible to high wear in service. It produces a much more uniform product, both dimensionally and structurally, as it does not suffer from turbulence.
