Title: Production of acyl halides and carboxylic acids and esters therefrom
Inventor: NORTON RICHARD V
IPC: C07C51/04
Filed: 1982-06-04
Abstract: In a carbonylation process for a producing acyl halides, e.g. acyl fluorides, the carbon monoxide and anhydrous acid such as hydrogen fluoride are premixed to form a single liquid phase which is reacted in a second reactor with an organic compound, i.e. an ester or an olefin, e.g. propylene, to produce an acyl halide, e.g., isobutyryl fluoride. In the second reactor the temperature is 0- 90 DEG C and the pressure 34-340 bars. The mole ratio of anhydrous acid to organic compounds is 1-100 moles of anhydrous acid per mole of organic compound and the mole ratio of carbon monoxide to organic compound is 1 to 5 moles of carbon monoxide per mole of organic compound. The acyl halide product may be hydrolysed to form the corresponding carboxylic acid which may in turn be oxydehydrogenated in the organic phase to form the corresponding unsaturated acid, e.g., acrylic acid or methacrylic acid.

Title: Apparatus for measuring a distance travelled particularly lift- measuring apparatus for stackers
Inventor: ROHR GUSTAV
IPC: B66F9/075
Filed: 1982-09-28
Abstract: In apparatus for measuring a distance travelled, particularly a lift, individual signals from a digital angular increment detector 7 are summed up and during the measuring operation are periodically compared several times with an analog signal, which is delivered by an analog transducer 15. These summed signals are corrected in dependence on any deviation before the lift signal is delivered. For this purpose, a signal counter is provided, which has a correcting input terminal and the count of which is adapted to be periodically corrected during the operation. The analog signal is sampled after each revolution of the lifts drive mechanism rotary drive, as determined by the angular increment detector, digitized, and then compared with the counter output corresponding to the summed signals from the angular increment detector. Any deviation is used to correct this counter output. The analog transducer is designed to measure the largest possible lift. <IMAGE>

Title: Compositions and processes for producing scratch resistant polysiloxane coatings
Inventor: GENT JOHN ARTHUR GOOCH
IPC: C09D183/06
Filed: 1986-09-17
Abstract: A prepolymer composition for forming a scratch-­resistant coating, comprising an acidic, aqueous solution of a polysiloxane prepolymer having non-co-reactive side groups and co-reactive side groups other than alkoxy, the composition being curable by evaporation of solvent and a decrease in acidity causing the co-reactive groups to react together to cross-link the polymer. Suitable co-reactive side groups are amino, epoxy and thiol. Suitable non-co-­reactive side groups are alkyl and gamma methacryloxy propyl. Acidity is suitably achieved by using a volatilisable organic acid such as acetic acid, so that it evaporates with the solvents to decrease the acidity.
