Abstract: 1294962 Esterification of polyvinyl alcohol EASTMAN KODAK CO 26 March 1970 [1 April 1969] 14864/70 Heading C3P [Also in Division C2] Esters of polyvinyl alcohols which may contain up to 25 mole per cent of acetate groups, are prepared by esterifying 10-50% of hydroxyl groups of the polyvinyl alcohol, i.e. 10-50% of the total number of hydroxyl groups that the polyvinyl alcohol can theoretically contain, firstly with an aroyl chloride which swells a suspension of P.V.A. in pyridine, and secondly with an acid chloride which does not swell such a suspension, and which has a melting point greater than 130‹C. Any residual hydroxyl groups after the above two steps, may be esterified with an aroyl chloride as defined above, which may be the same as or different from the one first used. The aroyl chloride is preferably selected from those of general formula where R is H, or a C 1-8  alkyl or alkoxy group such as benzoyl chloride, p-anisoyl chloride, ptoluyl chloride, or p-amyloxybenzoyl chloride and many others which are listed. The acid chloride of M.Pt. greater than 130‹ C. preferably is ethylenically unsaturated, such as a cinnamoyl chloride, an ethylenically unsaturated benzoyl chloride derivative, an acryloyl chloride or cyclohexadiene carbonyl chloride or an indene carbonyl chloride, many examples of these being listed. The latter give rise to light-sensitive polymers. In the examples various polyvinyl alcohols, some partially acetylated, are first esterified with benzoyl chloride and then with (1) 4 - (2 - cyano - 2 - carbethoxyvinyl) cinnamoyl chloride, (2) 4-[2-(4-amyloxybenzoyl)- vinyl] cinnamoyl chloride, and more benzoyl chloride (3) 4-(2-benzoylvinyl) cinnamoyl chloride, (7) as in (3) with a further addition of benzoyl chloride, (8) as in (2) but using 4-(2- benzoylvinyl) benzoyl chloride, (9) as in (2) but using 2 - (5 - styryl furan-2-yl) acryloyl chloride, (10) methyl 1 - [4 - (2 - chlorocarbonylvinyl)- benzylidene] indene - 3 - carboxylate, and benzoyl chloride, (11) 1,2-diphenyl-cyclo-propene-3- carboxylic acid chloride, and benzoyl chloride and (12) 1-methoxycarbonyl-4-chloroformyl-1,3- cyclohexadiene, and in others P.V.A. is first esterified with p-anisoyl chloride and then (4) 4-(2-benzoylvinyl) cinnamoyl chloride and more p-anisoyl chloride, (5) as in (4) but using pamyloxybenzoyl chloride instead of anisoyl, and (6) as in (4) replacing p-anisoyl chloride with ptoluyl benzoyl chloride.

Title: Fuel cell electrode - with metal grid coated with two conducting catalyst-contg porous layers having different porosities
IPC: H01M4/86
Filed: 1972-10-27
Abstract: Fuel cell electrode consists of an electrically conducting metal grid coated with (I) a catalyst-contg. electrically conducting layer which is suff. porous to allow the passage of gas and liquid and is enclosed in (II) a layer allowing the passage of gas but not of liquid. The catalyst-contg., electrically conducting layer I is divided into a layer (a) with lower porosity adjacent to the layer II, and a layer (b) with higher porosity.

Patent FR-2207214-A1 (FR)
Title: Printing textiles using off-set printing plate - to which dye is applied by pressing transfer sheet against plate
IPC: B41F16/02
Filed: 1972-11-22
Abstract: A pref. synthetic textile fabric (e.g. garment, upholstery) is printed using an off-set printing plate (e.g. formed by photo-engraving) to which dye is applied by pressing (e.g. in a printing press) a dye sheet against the dye plate (pref. for 15-20 secs. at 210 degrees C) so that the dye is transferred by sublimation to the imaged areas of the printing plate. The printing plate is then pressed (e.g. in the printing press) against the fabric (e.g. for 35 secs. at 210 degrees C) to transfer the dye to the fabric and so produce a dyed pattern. Pref. the printing plate is degreased before the dye is applied, and pref. after application of the dye the printing plate may be washed, lightly scrubbed, and treated with perchloroethylene to remove dye from the un-imaged areas. The transfer may be preliminarily hot pressed against a fabric to loosen the dye. The process can be carried out in a single press, and provides a better joint than when dye is transferred directly from an imaged transfer sheet.

Title: Aluminium foil wrapping machine for cheeses - is capable of excluding air completely from the wrapping
IPC: B65B25/06
Filed: 1973-04-04
Abstract: The machine will wrap any cylindrical shape with aluminium foil or other material in such a way that the wrapper will make perfect contact with the object. The cheese is held in a hollow space between 4 curved blades interspaced by rollers; the square sheet of aluminium foil covers the cheese and is folded over it when the cheese passes between the curved blades and rollers. The next stage in packing is to brush the packed cheese, so as to ensure that the wrapper makes contact with the cheese. The brushes and cheese rotate in opposite directions.

Title: Petrol consumption reducing fuel with naphthalene - decokes engine without the need for dismantling
IPC: F02B77/04
Filed: 1974-01-08
Abstract: A reduction in petrol consumption is achieved by adding 5 grammes of naphthalene to every 10 litres of ordinary or super grade petrol. For two stroke engines using a mixture of petrol and oil, 1 gram of naphthalene is added to 1 litre of mixture. For diesel engines, 50 grams are added to every 100 litres of fuel. The resultant mixture increases the octane number and increases the power and flexibility of the engine. The mixture also decokes the engine without the need to dismantle it, and keeps the piston heads, the valves and the sparking plug electrodes clean. Fuel consumption is also reduced by five to fifteen percent.
Patent FR-2323367-A1 (FR)
Title: Pressure mouth impression support - has elastic membranes forming chamber inflated via valve with air or fluid
IPC: A61C9/00
Filed: 1974-01-07
Abstract: The support is for taking of mouth impressions under pressure in order to manufacture false teeth. It has a built in pneumatic device which generates a peripheral pressure to give a joint effect, so that the impression can be taken under pressure. This device comprises two elastic membranes glued together along the periphery so as to form an inflatable chamber. Into this air or fluid is delivered by a valve fitting in a perforation in one of the membranes. A rigid impression support is perforated at the top and allows the impression substance to exert peripheral pressure, crushing at the centre the pneumatic device between the support and the rigid cover.

Title: Postal sorter with automatic control - allows sacks to fall into chute and has flaps operated to guide sack into selected channel
Inventor: PALUMBO CHARLES MARC ANGELO
IPC: B07C3/00

Abstract: The postal sorting system includes a conveyor with an automatic control system for the feed of sacks of parcels on a belt conveyor. At the discharge end is arranged a set of e.g. four chutes, each with three alternative channels (3,4,5) to discharge the sacks to the next station. Each channel carries a detector (22) to monitor the filled or empty stat eof the channels. Between each chute and the channels below are two independently operated swinging flaps (1,2). When a sack is discharge into the chute, the flaps can be operated by the control system, depending on signals from the sectors (22) to divert the sack to any selected channel of the three. The sack falls by gravity through the channel, past further flaps (7,8,9) at the bottom onto a conveyor below.

Title: Treating dust esp. in (coal) mines - using aq. or powdery compsns. contg.10-100 percent potassium carbonate
IPC: E21F5/06
Filed: 1975-03-27
Abstract: A compsn. for use in preventing dust, partic. in mines and esp. in coal mines contains >10% and up to 100% K2CO3. The dust is hazardous on health (silicosis) and explosive grounds.
