Title: PVC Plastisols foamable by beating, prodn. - by adding plasticiser contg. methylene chloride or 1-3C alcohol to PVC powder
IPC: C08J9/30
Filed: 1973-10-25
Abstract: Plastisols are prepd from vinyl chloride (co)polymer powders suitable for beating into foams (ie contg. emulsifiers) using rapid mixers, with the improvements that the plasticiser initially added to the mixer contains 1-6wt% (based on polymer to be added) of methylene chloride or 1-3C aliphatic alcohols. The liquids prevent rapid increase of viscosity on adding polymer, allowing more rapid addn. for shorter mixing time, and act as antifoams. The plastisols can be foamed and gelled conventionally to give eg synthetic leathers, carpet baskings etc.

Patent FR-2253608-A1 (FR)
Title: Method of fixing wooden handle to hammer head - involves surrounding split, wedged open handle end with synthetic material
IPC: B25G3/28
Filed: 1973-12-06
Abstract: The method is designed to prevent the handle loosening at the joint due to moisture changes within the wood of the handle. The step reduced handle end is inserted in a head aperture (3) and retained by a metal wedge (8) driven into a diametrical slot in the end of the handle which is of lesser length than the depth (L) of head aperture (3). The wedge is of lesser width than the handle end and lesser depth (d) than slot depth. The assembled joint is thus recessed w.r.t. the head and incorporates voids around the wedge, these voids finally being filled with a synthetic insulator which is applied as a liquid or paste which hardens with time.

Patent FR-2226720-A1 (FR)
IPC: G11B15/02
Filed: 1974-03-26
Abstract: 1467158 Data processing system SIEMENS AG 5 April 1974 [18 April 1973] 15304/74 Heading G4A In a data processing system including a plurality of magnetic tape units connected via one or more control units to a central unit where the tape units are such that following a power failure they must be reset before they can be controlled by the central unit, the central unit issues a RESET command to which the control unit(s) respond to reset the tape units, and to rewind any tape units which were operating when the failure occurred through a fixed distance or to a fixed marker, e.g. the tape leader. The tape units each include a manual switch to render them operative under control of the central unit which, following a power failure, issues a special command which is decoded to actuate selected switches remotely. The tape may then be rewound for a time determined by a monostable circuit which is reset if the tape leader is reached. Alternatively rewind operations may continue for a fixed number of sectors on the tape. To restart a record or replay operation the rewound tape is advanced until the block in which recording or replay was being performed at the occurrence of the fault is detected whereupon the operation restarts.

Title: Device for winding a cable on a drum - has cable guide stepped along rotating drum after each drum revolution
IPC: B65H54/28
Filed: 1974-06-11
Abstract: The cable to be wound is held between two rollers, which are carried in a housing on a spindle which has a number of grooves. The grooves are annular over part of the circumference, and helical over the remainder. The pitch of the helical part of the groove is the same as that of the diameter of the cable being wound. The spindle is connected to the main drum by a belt drive. When the cable is being wound on the drum, then it is maintained at a constant distance from the flange of the drum, until a turn has been wound on. The mechanism then moves the centre of the cable through one cable diameter so that the cable is wound with annular turns connected by short helical lengths.

Patent FR-2279342-A1 (FR)
Title: Desulphurisation of sugar juices - by spraying in counter-current with heated nitrogen
IPC: C12G1/04
Filed: 1974-07-26
Abstract: Desulphurisation of sugar juices comprises spraying the juices in counter-current with gaseous nitrogen. The plant comprises a vertical, cylindrical sepn. column fitted with two sets of spraying nozzles. The juice, previously heated to 85 degrees C. in a heat exchanger (I), is pumped through the jets to meet the rising current of nitrogen at 150 degrees C., passing through a packing of metallic gauze to ensure a uniform distribution of the gas. The nitrogen entrains the sulphur dioxide; it leaves at the top of the sepn. column and is passed through milk of lime in a recipient. When stripped of the SO2, the nitrogen passes through a heat exchanger (II) to be heated to 150 degrees C and returned to the sepn. column. The desulphurised juice collects at the bottom of the column and is pumped through the high temp. side of the heat exchanger (I); it leaves at 21-25 degrees C and leaves the plant via a valve. By lowering the temp. of the juice contg. the sulphur, combined with the reduction in the dwell time, the conditions are partic. favourable and the quality of the juice is improved.
Patent FR-2281155-A1 (FR)
Title: Removing dust from furnace gases - in plant with two operational stages involving expansion with decantation and washing
IPC: B01D47/06
Filed: 1974-08-07
Abstract: A plant for removing dust from furnace gases has two operational stages. The first stage in which larger particles separate by decantation, incorporates an expansion chamber which has a large sectional area in relation to the furnace flue and which has a roof which acts as a deflecting arch, giving the gases a horizontal velocity component towards a vertical wall. The wall acts as a baffle directing the gases downwards to a passage to the second stage, in which smaller particles are removed by washing. The second stage incorporates water atomisers and means of creating several streams across which the gases flow. There is a collector below each stage, for dry dust and mud respectively. The walls may be covered with a refractory lining and there may be an insulating lining and a fan and burners at the outlet of the furnace. One plant may be connected to a battery of furnaces with externally controlled valves. The plant reduces the amount of dust discharged by furnaces as legislation demands in regard to atmospheric pollution, more economically than existing plants which use filter stockings, cyclones and electrostatic processes.
Patent FR-2281898-A1 (FR)
Title: Complete oxidn., purificn and settling device - for waste from small communities
IPC: C02F3/04
Filed: 1974-08-12
Abstract: Total oxidn., purificn. and settling device, for wastes from small communities, is packed with a dense layer of hairs, to slow down the rising air bubbles and sub-divide them into smaller bubbles; they also retain the activated sludge and accelerate flocculation. The oxidn. yield is considerably improved. The air bubbles are retained in the effluent for a longer time and the oxidn. yield is therefore increased. The recirculation of the sludge is effected by the energy necessary for oxidn.; no additional energy is required.

Abstract: A hard sintered alloy comprises 70-97% of a hard phase contg. >=73% cubic TaN (the rest of the hard phase being formed from at least one other cubic Gp. 4 or Gp. 5 metal carbide or nitride) and 3-30% of a binder contg. at least 70% of Fe, Ni or Co and optionally is not >30% of a Cr. Mo or W. The hard alloy is prepd. by mixing the constitutens and sintering at 1400-1700 degrees C under 30-200 bars N pressure and rapidly cooling. The alloy is used for cutting tools. Since cubic TaN has a hardness is approx. 3000 HV the sintered alloy can have a hardness >1600HV.
