Title: Production of press boards
IPC: B27N3/12
Filed: 1973-07-11
Abstract: 1401900 Pressed panels R JETZER 11 July 1973 [14 July 1972 11 Jan 1973] 33058/73 Heading C3N [Also in Division B5] Pressed panels are produced from organic fibrous material by mixing the fibres with a curable synthetic resin binder, vibrating the mix to form a loose press cake, precompressing and simultaneously or subsequently heating the cake at 40-100‹ C. at least over 30 seconds and subsequently pressing the cake at temperatures over 100‹ C. until the synthetic resin binder has cured. The fibrous material may be composed of 33% by weight of wood shavings and 67 % by weight of other organic fibrous material. This starting material contained 5% by weight water and was sprayed with 10À5% of its total weight with a synthetic resin binder, e.g. urea formaldehyde or phenolic resin, which contains 5% by weight water based on the total weight of the synthetic binder. During the precompression the height "h" of the press cake is preferably reduced by 30-80%, e.g. 40%, of the difference "h-c" between the press cake height "h" and the finished thickness "c" of the panel. The press cake may be heated at 85‹ C. over 45 seconds simultaneously with or following the precompression. In a process using a single stage press the fibrous material is sprayed with synthetic resin binder and vibrated on a base plate to form the press cake. The press cake is introduced between the pressing rams of a preliminary press which are fitted with high frequency electrodes for heating the press cake. After precompression the cake is introduced between the rams of the main press which are also heated and have a temperature of 130-200‹ C. Fig. 4 illustrates a continuously working apparatus for carrying out the process in which fibres 13 mixed with resin are supplied from a conveyer 12 to a spreading wheel 14 which spreads them on to a continuously moving steel belt, thus forming a press cake 16 (50 mms. in height). This passes to a preliminary press 17 which precompresses the cake to a thickness of 20 mm. after which it is conveyed through two high frequency electrodes 19 at such a speed that the press cake is heated over at least 45 seconds at 85‹ C. The press cake 16<SP>1</SP> is then pressed in a heatable continuous throughput press 20 consisting of two oppositely rotating pressing plates at a temperature of 160- 200‹ C. to form a plate 16" with a thickness of 10 mm.

Title: Improvements relating to apparatus for making electric lamps and the like
IPC: H01K3/10
Filed: 1952-12-31
Abstract: 712,090. Making electric lamps and discharge devices. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 31, 1952 [Jan. 2, 1952], No. 33099/52. Class 39 (2) Apparatus for forming open hooks 7, Fig. 2, in the ends of leading-in wires mounted in the stems 2 of electric incandescent lamps, discharge devices &c. preparatory to the attachment of a filament or the like to the leading-in wires, and adapted for high speed operation in association with a turret machine of known type which carries the stems, comprises a backing member 12, Fig. 1, mounted so that it positioned closely behind a pair of wires 3, 4 to be operated on and consisting of a vertical plate-like member, preferably in the form of a U with its arms disposed horizontally, encompassing a bending finger 13 which engages the ends of the wires and is mounted eccentrically relative to the horizontal axis of a supporting shaft, so that when the latter is rotated the ends of the wires are bent around an anvil member 25 that has been brought into abutment with the side of the wires remote from the finger 13. The backing plate 12 is attached to a slide 17 plate that is movable vertically within a guide plate 18 under the action of a cam actuated rod 19, the slide plate being provided with lugs 22, 23 engaged respectively by a compression spring 20 and a collar 24 on the rod. The bending finger 13 comprises an eccentrically positioned flat portion on the end of a shaft 14 which carries a pinion 87 and is journalled within a housing 16 mounted on the slide plate 17, there being an idler pinion 39 located between the pinion 37 and rack teeth 38 provided on the rod 19. Normally the slide plate 17 and the bending devices are held in an elevated position to enable the jaws 10, 11 of the turret 'to bring a stem 2 with sealed leading-in wires 3, 4 to the bending station, whereupon the rod 19 is moved downwardly to bring the lower horizontal limb of the backing plate 12 behind the pair of wires 3, 4 and a stop-screw mounted on the guide plate behind the slide 17 prevents further downward movement of the latter. Towards the end of the movement of the slide 17 an adjustable screw 29 engages the operating end of a toothed section 30 pivoted in a bracket 28 entending forwardly from the guide plate 18, the sector being in driving engagement with a sector 34 on a pivoted arm 26 carrying the anvil 25 which is thus swung upwardly either into abutment with or adjacent to the pair of wires 3, 4. The rod 19, however, continues to move downwardly against the compression of spring 20, with the result that the rack portion 38 of the rod 19 becomes operative to rotate the shaft 14 so that the finger 13 bends the ends of the wires into open hook form about the anvil. Retraction of the several members then takes place to allow the stem to be indexed to the next work station. Specification 264,805, [Class 39 (ii)], is referred to.

Abstract: 1375871 Alpha-methyl styrene-siloxane block copolymers DOW CORNING Ltd 7 July 1972 [15 July 1971] 33285/71 Addition to 1308459 Headings C3P and C3T A siloxane-organic block copolymer in which the organic blocks are derived predominantly from α-methylstyrene is prepared by (a) polymerizing α-methylstyrene in an aprotic organic solvent in the presence of a lithium-containing anionic initiator at below 20‹ C., (b) adding a cyclic organotrisiloxane and an anionically polymerizable organic monomer whose anion can react with the trisiloxane, still at below 20‹ C., so that one or more units (preferably 1 to 6) derived from the monomer become attached to at least some of the living polymethylstyrene chains and (c) allowing the trisiloxane to polymerize on to the polymer chains in the presence of a polar aprotic organic solvent. The organic substituents on the silicon atoms of the trisiloxane are hydrogen atoms, monovalent hydrocarbon groups or #-perfluoroalkylethyl groups, no silicon atom being bonded to more than one hydrogen atom. The monomer added in step (b) may be 1-vinylnaphthalene, butadiene isoprene, acrylonitrile, 2- or 4-vinylpyridine, thiacyclobutane, methyl thiacyclobutane, propylene sulphide or, preferably, styrene. Polymers having a polymer block derived from α-methylstyrene joined to a block derivable from one of the specified siloxanes by y units derived from one of the specified monomers, where y is from 1 to “of the number of units in the methylstyrene block, are claimed per se. The polymers may be recovered directly after neutralization, e.g. with CO 2  or Me 3 SiCl, but they are preferably coupled by reaction with a compound having at least two reactive groups, e.g. a silane, siloxane or disilylethylene having at least two halogen substituents. They may be compounded with other polymers such as polystyrene or poly- (α-methylstyrene). In examples the linking monomer is isoprene or styrene and the siloxane is hexamethylcyclotrisiloxane; only a part of the siloxane is added with the other monomer, the remainder being added when a siloxanolate anion has been formed on the polymer chain. The resulting living polymers are coupled with (ClSiMe 2 ) 2 O, (Cl 2 MeSiCH 2 ) 2  or or terminated with Me 3 SiCl.

Patent GB-647971-A (GB)
Title: Improvements in preparation of isopentenyl propyl ketone
IPC: C07C49/20
Filed: 1947-12-19
Abstract: Isopentenyl propyl ketone is prepared by heating n-butyraldehyde with isoprene in proportions ranging from 1 to 20 mols. of butyraldehyde per mol. of isoprene in the presence of dibenzoyl peroxide at a temperature of from 65 DEG  to 100 DEG  C. until the isopentenyl propyl ketone is formed and then isolating the same.  Generally, a large excess of aldehyde is used; as an alternative to using an excess, the isoprene may be added incremently to the reaction mixture, thus in effect maintaining a considerable excess of aldehyde throughout the major portion of the reaction.  The reaction time generally varies from 1 to 50 or more hours depending on temperature, pressure and acceptable yield of ketone produced.  Pressures greater than atmospheric are used if necessary to keep the reactants in the liquid phase.  A suitable amount of catalyst is from 0.5 to 15 mol. per cent of the isoprene.  The ketone may be recovered by removal of unreacted material and fractionation of the residue.  In the example, 68 parts by weight isoprene are added dropwise over 20 hours to 720 parts n-butyraldehyde in presence of dibenzoyl peroxide at 80-85 DEG C. and the mixture heated a further 11 hours-6.8 parts of the desired ketone are recovered.  The Specification as open to inspection under Sect. 91 relates to the production of ketones by reacting a conjugated diene with an n-alkanal, sec.-alkanal, cycloalkanal or an aralkanal under free radical conditions.  The products are stated to have the general formula R-CO-(X)n-H where R is the radical derived from the aldehyde, X is the bivalent radical derived from the diene and n is an integer from 1 to 9.  Reactants mentioned are acetaldehyde, propionaldehyde, butyraldehyde, isobutyraldehyde, heptaldehyde, octaldehyde, cyclopentanal, cyclohexanal, phenylacetaldehyde, and butadiene hydrocarbons such as butadiene-1 : 3, 2-methyl-butadiene-1 : 3, 2 : 3-dimethyl-butadiene-1 : 3 and piperylene.  The source of free radicals may be ultra-violet light or a compound which decomposes to give free radicals such as organic peroxides, e.g. acyl peroxides such as diacetyl peroxide, dibenzoyl peroxide, acetyl benzoyl peroxide, alkyl peroxides such as t-butyl hydroperoxide; hydrogen peroxide; per-salts, e.g. alkali persulphates, percarbonates and perborates; hydrazine derivatives such as hydrazine sulphate, hydrazine hydrochloride and dibenzoyl hydrazine; organo metallic compounds such as tetraethyl lead.  The reaction may be carried out in the presence of inert diluents such as n-hexane, benzene or cyclohexane; temperatures of 25 DEG  to 150 DEG C. may be employed while pressures up to 2000 lbs. per square inch may be used when the diene is normally gaseous.  This subject-matter does not appear in the Specification as accepted.

Abstract: 618,920. Twisting crank-shafts. FITZPATRICK, H. J. (Clearing Machine Corporation). Nov. 13, 1946, No. 33645. [Classes 83 (ii) and 83 (iv)] A crank-shaft twisting machine comprises clamping dies on a base co-operating with dies on a press head for holding certain cranks stationary and co-operating clamps on the base and the press head which after closing are rotated to twist other cranks on the shaft. Separate means is provided for reversely rotating the clamps on the press head. A six-throw crank-shaft forged with the cranks in one plane is inserted into a press with clamps 29 on the base co-operating with clamps 34 on a press slide 23 for holding the end journals and cranks 2, 5. Cranks 1, 3, 4, 6 are clamped between members 39 on the base and members 40 on the slide. When the press head is lowered, the members 39, 40 are locked and rotated in the appropriate directions by hinged members 46, 47 actuated by cylinders 50, 51 to angles determined by adjustable screwed stops 69 on the press head. When the press head is raised, the upper clamps 40 on the head are rotated to normal position by cylinders 59 with pistonrods 60 engaging racks 63 on the clamps 40. Ejector mechanism comprises a beam 72 supporting rods positioned under the crank journals. After twisting, the press head 23 is raised by cylinders 26 to separate the clamps and attached cylinders 75 carrying detents 77 are lifted and engage beneath heads 74 on rods 73 attached to the beam 72 to lift the rods and the shaft for removal. Hand operation of a valve 86 releases the detents 77 to allow the beam to drop by gravity to an inoperative position. In operation, the shaft is positioned and the press head is lowered by cylinders 26 to close the fixed clamps 29, 34 and the rotary clamps 39, 40. The cylinders 50 swing the actuators to rotate the clamps 39, 40 to effect twisting. The slide is then raised and pressure is admitted to the cylinders 51 to rotate the lower members 39 to normal position after a stop 66 on the press head has operated a valve 65 admitting pressure to cylinder 59, restoring the clamp 40 to normal position and the beam raises the shaft ready for removal.
