Filed: 1976-01-20
Abstract: 1497504 Hook COLUMBUS McKINNON CORP 20 Jan 1976 [10 Feb 1975] 02109/76 Heading E2A A safety hook comprises a hook 12 to which is pivoted a moving piece 14 and which has a latch 18 to hold the mousing piece 14 in the "hook-closed" position. The latch 18 comprises a dumb-bell shaped member 50 received in a bore 30 in the body of the hook 12. Member 50 is biased by spring 52 towards the latching position in which it is retained by lug 32 and in which the enlarged end 50b engages a notch 46a formed in rib 44 on the back of the mousing piece 14. The latch is released by pushing end 50a against the bias of spring 52 so that end 50b no longer engages notch 46a. The hook may then be opened manually. The mousing piece is frictionally maintained in the open position by engagement of the face 44a of rib 44 with the inside face 50b' of the end 50b. The hook is generally I-shaped in cross section; this, together with the lug 32 forms a convenient hand-grip for the operator.

Title: Process for producing commercial shapes from metal and metal coated powders and mixtures thereof
IPC: B22F3/18
Filed: 1962-01-22
Abstract: Shaped sintered parts are made from metallic powders and/or metal coated powders having a particle size of 0.1 to 300 micron by forming a green strip having a density of 45-95% of theoretical, slitting the strip into several strips, stacking at least two of the strips, sintering the stack at a temperature below the melting temperature of the principal component and finally working the sintered stack, preferably by rolling, to 100% density.  As shown in the drawing the powder 20 mixed with 0.1-2% of a binder such as water, carbon tetrachloride or <PICT:0943365/C3/1> alcohol is rolled at 22, 23 to form a green strip 24. The strip 24 is slit at 30 either in the green state or the presintered state to form strips 31a, 31b 31c, 31d which are then stacked, sintered in furnace 33 in hot and/or cold rolled at 36, 37. Rolls 36 and 37 may be shaped to produce any required form in the finished stack. The metal powders specified are Pb, Sn, Ni, Cu, Fe and Co and either strips of similar materials may be stacked together or dissimilar strips are stacked together to form laminates, e.g. Ni-Fe-Ni-Fe. Examples are given of the formation of Ni parts, Ni-Fe composites, a Cu coated Ni core and a Co rod.  The sintering atmosphere may be inert, neutral or reducing.

Filed: 1966-01-21
Abstract: Organic plastics material is produced by mixing at least 95 parts of molten linear polyamide having a relative viscosity of 1-6 with up to 5 parts of a polyolefine in the presence of air or oxygen, solidifying the mixture and heating the solid in the presence of an inorganic acid, acid salt or acid ester as catalyst and in the absence of oxygen at a temperature below the M.P. of the polyamide to further polymerize it until its relative viscosity has risen by at least 1 unit.  Polyamides specified are poly-e -caprolactam containing about 2% water-soluble material, polyenantholactam, polycapryllactam, polylaurolactam and polyhexamethylene adipamide. Polyolefines specified are high or low pressure polyethylene of 0.91-0.97 specific gravity and 0.2-20 melt index, polypropylene of 0.5-20 melt index and polybutylene. The solid mixture may be heated in a granular state at at least 110 DEG  C.  10-3-10-5 mols. of catalyst, e.g. sulphuric acid phosphoric acid, potassium hydrogen sulphate or methyl hydrogen sulphate may be present.  Any water vapour produced may be partially or entirely removed, either by application of a reduced pressure, e.g. less than 15 mm. Hg or by presence of an inert liquid, gaseous or solid medium, e.g. N2 at atmospheric pressure.  In addition to catalyst, the solid mixture may also contain an inorganic, or organic pigment or SiO2 or silicate which will pass through a sieve of 80 meshes per cm.  In examples the ingredients are mixed in a screw extruder, the extruded thread cut into granules and the heated granules shaped into a bottle (I) or a sheet (II).

Title: Recovery of the rhodium and triphenyl phosphine components of a catalyst system used in a hydroformylation process

Abstract: 1495025 Recovering the rhodium and triphenyl phosphine components of a hydroformylation catalyst MONTEDISON SpA 23 Jan 1975 [23 Jan 1974] 3046/75 Headings C2P and C2C Rhodium and triphenyl phosphine are recovered from crude hydroformylation products obtained by hydroformylation of olefins in the presence of a catalyst complex comprising rhodium and triphenyl phosphine, or from the tails left after distillation of the crude products to remove the desired hydroformylation products, by treating the said crude products or the tails at 60 to 150 C. with an aqueous solution of a C 1 -C 4  aldehyde and of a strong mineral acid, the molar ratio for each of the aldehyde and the acid being from 1 : 1 to 1 : 3 with respect to triphenyl phosphine, separating the solid rhodium complex formed by filtration and decanting the aqueous solution containing triphenyl phosphine. Specified aldehydes for use in the process are formaldehyde and isobutyraldehyde and specified mineral acids are hydrochloric, sulphuric and perchloric acids. The process may be conducted in the presence of air but is preferably carried out under an inert atmosphere, e.g. a nitrogen or carbon monoxide atmosphere. When the aldehyde used is formaldehyde and the acid used is HCl and the molar ratio of each of the aldehyde and HCl to the phosphine is substantially one the rhodium complex separated by filtration comprises the compound: Rh(CO)Cl(PPh 3 ) 2  (where Ph is phenyl) and this may either be re-used as hydroformylation catalyst in the presence of an organic base which is added to bind the Cl atom or it may be converted into a monovalent hydride or carboxyl complex for subsequent use as catalyst. Solid triphenyl phosphine containing traces of rhodium compounds may be obtained from the decanted aqueous solution by adding an alkali, e.g. sodium carbonate, to the solution, and the resulting solid may be re-used in a subsequent hydroformylation reaction. Examples are given for the application of the process to a mixture of crude products formed by hydroformylation of propylene and from which n and iso-butyraldehydes have first been recovered by distillation, the aldehyde used being formaldehyde and the acids used being HCl and H 2 SO 4  respectively.

[Also in Group XL (a)] In a camera tube for converting colour television images into colour component signals the radiation-sensitive target incorporates separate groups of alternating electrode elements and colour filters (see Group XL (a)) and, in operation, the groups are stabilized at either cathode potential or at the potential of a grid arranged in front of the scanned side of the target, signals being obtained proportional to the magnitude of different colour components, but of opposite polarities. In a two-colour system with a photo-conductive target both signals may be derived from the target or one from the target and one from the returning electron beam. In a two-colour system with a photo-emissive target one signal is derived from the returning beam and the other from the grid adjacent the target. The returning beam falls on an electron multiplier. In a three-colour system two colour component signals are derived from the target and the third from the returning beam. The beam scans the target electrode elements transversely of their direction.
