Title: Polycarbonate prodn. - by phosgenating crystal hydrates of alkali salts of aromatic dihydroxy cpds in org suspension and polycondensing
IPC: C08G64/24
Filed: 1975-02-11
Abstract: Polycarbonates are made by interphase polycondensn. by phosgenation of alkali salts of aromatic dioxy cpds. (I) in the presence of a catalyst (II) and a chain stopper (III), whereby the (I) has the formula where R = -C(CH3)2- or cyclohexyl, R' = Cl or Br, M = Na or K, n = number of mols. of water in the crystal hydrate, m = 2, and the phosgenation is carried out with a suspension of one or two of the cpds. (I) in org. solvents such as methylene chloride or a mixt. of methylene chloride with high boiling chlorinated hydrocarbons at 5-40 degrees C to form oligocarbonates, and the oligocarbonates are subsequently subjected to polycondensation in the presence of a 5 to 20% aq. soln. of caustic alkali used in amts. of 0.3-0.7 mol per mol. (I) to form the polycarbonate. The phosgenation is carried out in the absence of water and free alkali, which prevents oxidative discolouration of the prod. compared to prior art processes, so that an inert atmosphere is not required for the process; second stage of the reaction is conducted with small amts. of water, thus reducing the water usage in the process and reducing the hydrolytic loss of phosgene.

Title: Forming of bosses in the bore of a tube - used for aligning concentric tubes in mfg. metallurgical lances
Inventor: ZANETTA HUGUES
IPC: B21D22/04
Filed: 1975-06-26
Abstract: Tool is for forming internal bosses in a tube by punching impressions in the outside surface of the tube. The tube is located on a mandrel and fed down the bore of a guide tube, the mandrel possessing grooves to match the bosses required. The tube is then aligned with two blocks, each contg. a counterbored hole for a punch.

Patent FR-2285275-A1 (FR)
Title: Fast acting electropneumatic train brake - with brake venting valves acting independently of main brake pressure
IPC: B60T13/68
Filed: 1975-08-20
Abstract: The electro-pneumatic train brakes have a relay valve with the main brake pressure on one side and the reservoir pressure on the other. The reservoir is fed via a throttle from the main brake line, or from the supply using electromagnetic control valves. The control valves are arranged so that they operate independently of the pressure level in the main brake line. They connect either to the supply line or to a venting line to atmosphere. This provides a fast acting braking system so that rapid brake application is possible by direct control in emergency braking.

Title: Separating proteins from aq. soln. contg. industrial effluent - by passing through ion exchange resin on mineral support
Inventor: MEILLER FRANCOIS
IPC: B01J47/00
Filed: 1975-08-28
Abstract: Process comprises passing a protein soln. though an ion exchange resin. The resin comprises a porous mineral support of 4 mu-k mm particle size, 5-150 m2/g specific surface, 500-2500A degrees pore dia., and 0.4-2 ml/g porous volume. The support is coated with 15 mg/m2 of a cross-linked polymer film contg. or bearing either anion exchange groups which are tert. amines or quaternary ammonium salts or cation exchange acidic groups. The exchange capacity is 2 m equiv./g. The process is used to separate protein from solns. such as lactoserum, beer, blood, body extracts and industrial effluent from abattoirs, the feed and starch industries, providing a purification means for these effluents. Cellulose or dextran ion exchangers used to separate protein are unsuitable for use in a column, undergo volume changes due to ionic force, are biodegradable and cannot be sterilised. The above having none of these disadvantages can be used to obtain very pure protein.

Patent FR-2334060-A1 (FR)
Title: Domestic heating system boiler - uses air from inside building for combustion
IPC: F24H6/00
Filed: 1975-12-03
Abstract: The boiler receives combustion air which has already been heated by the boiler and discharged into the building. The air comes from inside the building through inlet passages (3). The passage has a diverter valve (5) which takes away excess air through the passage (3') and discharges it outside. The air going through the boiler is also discharged through the passage (4). Fresh air is brought in from outside through the fan (13) and is circulated around the boiler in the space (7). Regulation is afforded by by-passing the boiler with the passages (9) and the diverter valve (10) which restricts the flow through the boiler.

Abstract: The adjustable travelling shutter may be used in reinforced concrete building construction to form room cells or rectangular section subways, and can be adjusted for length, height and width. The assembly forms two opposed internal wall faces (46) and the soffit (1). The soffit shutter is supported independently from the two independent wall shutters. The soffit shutter may be mounted on 'I' shaped frames (6, 11, 18) with rollers and the wall shutters on triangular frames (43, 47, 62) similarly on rollers (66). Walls may thus be constructed separately or continguously with the soffit. Two frames may be located at longitudinal intervals, may have lattice-braced upper arms (6) which travel up and down the head of the post, and may have independently pivotable lower arms (18). The base of the post may include an adjustable foot which descends to relieve the rollers, and the height of the wall forms nay be reduced by increasing the inclination of the telescopic stays (47).

Title: Easy chair converting into bed - has five successive inter-hinging frames, opens in two stages, three hinges aligning to counter folded mattress forces
IPC: A47C17/22
Filed: 1977-04-12
Abstract: The easy chair which converts into a bed incorporates five successively interhinging (A, B, C, D) metal frames in the conversion mechanism. the frames fold onto one another to form the chair seat, and two only operational movements are reuired to effect the conversion. With the frames retracted and folded three of the inter-frame hinges are in alignment. This arrangement produces frame stabilising moments which are in excess of those due to the folded mattress and tend to open the folded frame-work. After the primary operational movement the three frames (TE, QQ, Q1) remote from the chair back remain folded. At this stage two of the relevant inter-frame hinges are still in alignment counteracting the opening moments due to the residual folded mattress. The folding mechanism may include two pin-jointed lever arms (E.L. and LE) and a coil spring (M.L.).
