Title: Selective platinum/carbon carrier catalysts
Inventor: JOHN COOPER BARRY
IPC: B01J23/44
Filed: 1970-12-12
Abstract: The catalyst is specifically selective when hydrogenating mixtures of olefins, when linear olefins are hydrogenated, but not branched ones. The catalyst is prepd. by suspending a reducible metal cpd. (of Pt, Fe, Pd, etc.) in a polymerisable monomer, suitable also for carbonising (pref. furfuryl-(2)-alcohol), reducing the cpd. to the colloidal metal with formaldehyde, polymerising the monomer by warming in presence of H3PO4 and finally curing the polymer above 110 degrees C, all this under N2. The cured polymer is carbonised at 640 degrees C for 4 hrs. under N2. Active particles on the surface are poisoned to maintain the selectivity. Alternatively the catalyst may be coated with the above mentioned polymer, which is the carbonised as shown. The same treatment may be applied to a metal/carrier catalyst, the carrier being any other suitable substance. The catalyst is very resistance to poisoning.

Title: Phenolic resin binder for nuclear reactor fuel - obtd from phenol, cresol and hexamethylene tetramine
Inventor: JENKINS MANSEL JOHN
IPC: G21C3/62
Filed: 1972-02-15
Abstract: Phenolic resin binder for nuclear reactor fuel is obtd. by mixing 10 moles phenol, 4 mole o-cresol and 1 mole hexamethylene tetramine, heating the mixt. to form a soluble, fusible resin (stage I resin) and dissolving the resin in a solvent. Pref. a further 1/52 mole of hexamethylene tetramine is then added to the resin soln. (to provide rapid curing at temps. as low as 180 degrees C). Nuclear fuel is produced by adding the binder to graphite powder and introducing the free flowing powder into a revolving drum in which particles of fissile material precoated with fission product retaining material are tumbled, and the binder is softened by sprinkling the graphite powder entering the drum with solvent so that the precoated fuel particles acquire an outer coating of graphite grains by a snowballing effect. When the particles are evenly coated they are removed, heated to evaporate solvent, placed in batches in a cold die and pressed into compacts. These are removed from the die and heated to 180 degrees to cure the binder. The binder may subsequently be carbonised by further heating.

Title: Integral wear resistant lining for plastics pipe - is first formed around mandrel then reinforced pipe is formed around lining
Inventor: KERN HEINZ DIPL ING
IPC: B29C70/02
Filed: 1972-11-15
Abstract: A method of making a wear-resistant internal liner for a fibre-reinforced platics pipe, which is constructed by winding reinforcing fibres already impregnated with thermosetting plastics around a mandrel, is as follows: before the pipe itself is wound onto the mandrel, an inner layer is applied onto the mandrel; this inner layer contains, at least on the side towards the mandrel, wear-resistant granular material contained in a matrix of thermosetting resin. This arrangement obviates the need for the construction of a separate internal pipe to which the outer pipe is later applied, and results in a structure possessing generally equivalent properties, e.g., of thermal expansion, throughout its thickness.

Title: Bowling alley with automatic skittle reset - has traction rope, which moves skittles held fixed when skittle overturned
Inventor: LEIDL JACOB JOHN
IPC: A63D5/08
Filed: 1973-10-13
Abstract: Bowling alley with automatic skittle reset has a skittle scoop aligned above each skittle to replace it and an extra flexible traction rope to raise and lower the skittle. When a skittle is overturned in a game a mechanism picks up all the skittles using their traction ropes and only replaces those not overturned.

A pawl operating rod rests against the coupling arrangement to hold it in neutral. The coupling arrangements include friction elements which contact the traction ropes in a wedge shaped configuration.

Title: Sheet processing machine control system - uses non-interchangeable signals from first and second sheet edge feelers
Inventor: KISTNER HERMANN
IPC: B65H3/10
Filed: 1974-05-08
Abstract: Machine operation is controlled dependent on the position of sheets on a track along which they follow each other in succession, having two feelers acting against the sheet transverse edges at intervals along the track and a logic switching circuit with storage facilities combining and storing the signals from both of them. The first binary value of the circuit output signal represents detection of the sheet edge by the first feeler, and the second one that by the second one. The two feelers (10, 11) produce non-interchangeable signals as input signals for the circuit (34-37), and/or non-interchangeable signal paths are used. The signals from the two feelers can have opposite potential, and each can have a limiting circuit (31, 32) restricting signal duration to a predetermined value.

Title: Unit for converting solar energy into mechanical energy - provides for direct passage of radiant energy into working-medium
Inventor: POSNANSKY MARIO DIPL ING
IPC: F03G6/06
Filed: 1974-05-18
Abstract: In this process for covering solar energy into mechanical work, in which the radiant energy is concentrated by means of a reflector into an operative zone, the closed cycle of the working medium of a heat-engine is passed through that zone and the radiant energy is directly passed into, and absorbed by, the working medium. In this way, the working medium is taken to a higher temperature, so that the conversion process can be carried out with a considerably higher efficiency than was possible with processes and devices of the prior art.
