Title: Lever system for electronic weighing balance - has flexible strips for suspension and articulation of levers
IPC: G01G21/18
Filed: 1974-10-23
Abstract: Scales and balances for commercial use employ levers which articulate about knife edge supports and are generally large with low ratios. Greatly reduced size is achieved using a lever system employing flexible strips for suspension and articulation of the levers. A balance contains a rectangular support (2) on which flexible strips (3) are used to attach the arms of two T-shaped levers (4, 5). The longitudinal lever bodies are joined by a vertical flexible strip (7). A lower level support is attached to the lever arms (4b, 5b) by flexible strips (11) and is also supports the load platform. Thus a platform load pushes the support down to pull on the flexible strips (11) causing the lever bodies (4a, 5a) to rise simultaneously to operate an electronic weight detector.

Patent FR-2299940-A1 (FR)
Title: Bonding metallic bodies using insert - which forms reducing atmos. preventing oxide formation
IPC: B23K20/16
Filed: 1975-02-04
Abstract: Metal bodies are bonded together by sandwiching an insert that forms a reducing atmos on bonding, between the bodies, applying pressure to the assembly to pressure bond the material with super-plastic flow at raised temps. and simultaneously with the application of pressure alternately heating and cooling the assembly through a temp. range above and below the transformation temps(s). of the metal until a permanent bond is formed. In bonding knurled pipes, boiler steel pipes, cast iron parts etc. Even if unbonded parts are left on the surface, the high temps. do not result in oxide formation because of the presence of the reducing atmos. The compression stress can therefore be lowered and the established bonding is a strong one.

Patent FR-2267813-A1 (FR)
IPC: C07C315/06
Filed: 1975-04-14
Abstract: Bis(4-chlorophenyl) sulphone is removed from a reaction product obtained by reacting chlorobenzenesulphonic acid and chlorobenzene. The ratio of chlorobenzene to chlorobenzenesulphonic acid is selected in such a manner that the reaction product gives a crystallisation fluid in which the amount by weight of crystallisable bis(4-chlorophenyl) sulphone is no more than 10 g (based on 100 g of the mother liquor which can be obtained by crystallisation from a reaction product which has been prepared in an uncontrolled manner) below the maximum amount of crystallisable bis(4-chlorophenyl) sulphone which can be obtained when the ratio of chlorobenzene to chlorobenzenesulphonic acid is selected in an optimal fashion. The crystallisation fluid, which has been prepared in this manner, is then cooled to the crystallisation temperature of bis(4-chlorophenyl) sulphone, and the crystallised bis(4-chlorophenyl) sulphone is separated from the mother liquor. Bis(4-chlorophenyl) sulphone is an important monomer for the preparation of aromatic polymers. The process is economical and simple to carry out and gives an end product of high purity. The diluent already exists in the reaction mixture and can be recovered readily from the mother liquor obtained and then recirculated, which simplifies the process substantially.

Title: Rapid warm:up equipment for lubricant in air:cooled IC engines - has a perforated sump partition set in grooves in sump side walls
IPC: F02N19/04
Filed: 1975-12-05
Abstract: The rapid warm-up equipment for lubricant in IC engines, esp. air cooled ones, has the engine sump divided into 2 parts (Z1,Z2) by a perforated plate or wire mesh grating (9). This plate/grating is set into grooves (8) in the sump sidewalls and bottom plate so as to enclose a flat ring shaped chamber (Z2) around a central well (6) in which sits the oil pump intake (4). The perforation size/mesh width is so chosen that oil of the appropriate viscosity characteristic for the engine concerned will circulate through it freely only when it is at or near working temp. When the engine is cold, oil in the ring-shape chamber will thus not only not circulate with the rest, but also will act as an insulant between the circulating oil and the sump bottom plate.

Title: Hydrogen sulphide/sulphur dioxide absorption - in an amino-deriv solvent, producing sulphur
IPC: C01B17/05
Filed: 1976-01-20
Abstract: H2S and/or SO2 is removed from a gas by absorption with solvent (serving as the absorbing agent) selected from the group comprising aminoalcohol, an aliphatic amine, an alkyleneglycolamine, a polyalkylene-glycolamine, an aromatic amine, an amino acid, morpholin, primery, secondery and tert., the pH of which is 4-12, and more than two of org. bases, another org. solvent if necessary added, to precipitate elementary sulphur. The adsorption is improved by carrying-out the reaction under pressure with excess SO2 so as an unreacted portion of SO2 remains in the solvent after completion of the reaction and using said the SO2-containing solvent as the adsorbing agent. This process saves thermal energy previously required for stripping-off H2S from the solvent used for the reaction.

Title: Embossing mould with pattern plate separate from heat sink - for short moulding cycles and low heat swing capacity
Inventor: CHARLES PATRICK
IPC: B29C59/02
Filed: 1976-02-09
Abstract: A mould tool is for pressing designs or patterns into the surface of a layer of material contained in a silicone rubber mould and softened by high frequency induction heating. The pressure is generated by evacuating the interface between the filled cavity mould and a think flat plate bearing a negative relief pattern of that required or the mould tool leading to channels surrounding the mould. The borders of the plate may be supported by resilient pads enclosing the channels. The moulding is subsequently chilled by applying a cold body, specifically a metal block on a liquid cooled panel, against the upper face of the plate. Used esp. for creating embossed patterns into large flat or shallow mouldings. Moulding cycles and energy swing losses are reduced because the heat sink block or panel remains permanently cool. Use of vacuum avoids need of high pressure thrusts to apply the necessary moulding pressures.
