Title: Process for the production of foamed synthetic resins
Inventor: WAAG THEODOR
IPC: C08J9/00
Filed: 1964-12-14
Abstract: The production of foamed synthetic resins from mono-, di- or tri-methylol ketones, directly according to the parent Specification or via the precondensates of Specification 1,031,579, is modified by the addition before foaming of finely divided materials of organic or inorganic origin such as kaolin, ground mica, Al stearate, asbestos flock, and natural or synthetic organic fibres.  Such materials, preferably prepared by grinding or by precipitation, may be used in proportions of at least 1% by weight and preferably 10-60% by weight of the total reaction mixture.  Acetone methylol compounds are preferred starting materials.

Abstract: 1,096,944. Feeding fibres to machines. F. REITERER and L. WINDISCH. Dec. 15, 1964 [Jan. 4, 1964], No. 51041/64. Heading D1N. A shaft supplying fibres to a carding machine has one or more partitions extending and arranged to reciprocate longitudinally within it and one or more, preferably two, oscillatable flaps pivoted near its lower end. The partition 7 which is provided at its bottom end with a tamper 36 may be raised by an eccentric 28 driven from the doffer of a carding machine and may descend by its own weight. Other eccentrics 33, 33' are driven from the shaft of eccentric 28 and bear upon flaps 9, 9' so affecting the latter that they are in a closed position when the partition 7 is in its uppermost position. The bottom of the shaft is closed by compressing rollers 11, 11' that feed the fibres from the shaft in association with a conveying roller 12. In order to prevent overfilling of the shaft, feeding flaps are located at its upper end and are connected to discontinue the supply of fibres if necessary. The surfaces of the partitions and flaps may be constituted by a material that electrostatically attracts dust and the carding machine may include a device to break this attraction when required.

Abstract: 1411550 Feeding sheets EASTMAN KODAK CO 6 Nov 1972 [5 Nov 1971] 51055/72 Heading B8R In a copying machine, a supply hopper (12, Fig. 1) for stacked documents to be copied is located above the exposure station 17. A feed roller 22 advances the first document from the top of the stack along the travel path through separator rollers 27, 30 and a turn round mechanism 15 to an index position 32 adjacent the exposure station 17. The arrival of the leading edge of the first document at the index position 32 is sensed by a photoelectric detector 72 which activates the feed roller 22 to advance and hold in the index position a second document while the first document is being advanced by a conveyer across the exposure station 17. A second photoelectric detector 78 senses the arrival of the leading edge of the first document in the position overlying the exposure station 17, resulting in deactivation of the conveyer system so that the document is held stationary during exposure. Completion of exposure results in re-activation of the conveyer system to advance the first document to feed rollers 34, 35 which deliver the first document to a hopper 16, and forwarding of the second document from the index position 32 to the exposure station. A third document, if available, is advanced to the index position 32, so repeating the operation.

Abstract: 516,188. Making emulsions. DEUTSCHE HYDRIERWERKE AKT.-GES. July 11, 1938. No. 20530. Convention date, July 10, 1937. [Class 1 (i)] [Also in Group IV] Products stated to have emulsifying properties are obtained by condensing a benzylchloride sulphonic acid or salt thereof with an aromatic hydroxy compound having a nuclear aliphatic or cycloaliphatic residue with at least three carbon atoms or its metal derivative. In examples, sodium benzylchloride-p-sulphonate is condensed with octylphenol or the phenol obtained by condensing tech:cresol with an unsaturated hydrocarbon derived from benzine or from carbonmonoxide and hydrogen.

The nuclear aliphatic group may contain halogen, oxygen, sulphur or nitrogen or groups containing these atoms. The Specification as open to inspection under Sect. 91 comprises also the production of emulsifying agents by the condensation of any halogenalkylarylsulphonic acid with an aromatic hydroxy compound having a nuclear aliphatic or cycloaliphatic residue with at least three carbon atoms.

Abstract: 1,081,370. Producing electrical components; jointing by stamping; jointing by forging. UNITED-CARR Inc. Dec. 21, 1964 [April 8, 1964], No. 51866/64. Headings B3A, B3H and B3Q. [Also in Division H2] The tail of an electric contact is formed from sheet metal which is initially bent into a U- shape and has a round cross-sectioned wire inserted to the bottom of the U. The arms of the U are subsequently bent around the wire so that the free ends substantially meet along a seam, and this is then inserted into a die which compresses it until the assembly has a square cross-section with four relatively sharp corners which form good contact with a wire wrapped around it. If the inserted wire is of soft copper this deforms with the sheet metal so that the final shape of the sheet metal is square both on its inside and outside surfaces. However, if the wire is for example piano wire, then the inside shape of the deformed sheet metal conforms to the original round cross-section of the piano wire, which may subsequently be removed. With the use of the removable piano wire the forming of the tail may be carried out automatically and the contacts moved from one station to the next, each station having a piece of piano wire with a painted free end to receive the partially formed contacts. In alternative embodiments (e.g. the embodiment shown in Fig. 10) the arms of the U, need not be folded completely round the wire 42 and the specially shaped moving die 49 having a projection 48 deforms the contact so that it has the required four sharp corners but is open to the cone along one of its sides.

The drive circuit shown in Fig. 3 receives at input 10 a squarewave 10a derived from the timing circuitry and which is also applied to the display common electrode. The voltage 10a passes, via inverter 14, to exclusive OR gates 19, 20. A ratio control voltage 11a, e.g. of half the frequency of 10a, is fed to input 11 and thus to AND gates 17, 18. Display segment control signals 12a, 13a are fed to inputs 12, 13 to control the AND gates. Fig. 4 shows the AND gate outputs 17a, 18a for a high input to 12 and a low input to 13. The resulting voltages 15a, 16a at output terminals 15, 16 are fed to two display segment electrodes. The drive voltages between the latter and the common electrode are thus the intermittent alternating voltage 10-15a and zero as at 10-16a so that the correspondong segments are respectively ON and OFF.
