Abstract: 1,169,032. Separating particulate material; coating apparatus; catalytic apparatus. OTDEL MEKHANIKI POLIMEROV AKA DEMII NAUK BELORUSSKOI SSR. 7 Nov., 1966, No. 49774/66. Headings B1F, B2H and B2L. [Also in Division H2] In an apparatus for the fluidization or separation of particulate material, vibratory motion at least in three different directions in at least one plane is imparted to at least part of a chamber containing the material by means of at least three electromagnets. In the apparatus shown in Fig. 1, the lower part I of the container is supported from the upper part by resilient means 2. The bottom of the part 1 may be either porous or in the form of a mesh. Electromagnet armatures 3 are secured to the bottom of the part 1. Alternatively, the bottom of the part 1 may be made of a ferromagnetic material. Affixed to the body 8 of the apparatus are horizontally disposed stators 4, 10, 11, 12, 5, 15, 14, 13, Fig. 2, surrounding the part 1 and vertical stators 6, 16-20, 7, 21 located below the part 1. The electromagnets are energised by means of a timer consisting of a time delay relay, Fig. 3, comprising units 22 and 23 for controlling respectively the vertically and horizontally disposed electromagnets. Relays 24 ... 27 are each furnished with four contacts 24<SP>1</SP> . . . 24<SP>1111</SP>, 25<SP>1</SP> . . . 25<SP>1111</SP> &c. serving to actuate the relays consecutively in closed cycles. The sequence of electromagnet switching is first present by using bipolar plugs (not shown) to connect the windings of the stators to contact unit sockets 28 . . . 32 with a chosen switching sequence. Switching frequency is determined by resistors 33, 34 and capacitors 35-38.

Abstract: 1,161,200. Unloading aircraft in flight. VAN ZELM ASSOCIATES Inc. 2 Nov., 1967, No. 49864/67. Heading B8E. [Also in Divisions E1 and F2] An energy absorbing system comprises a metal strip, wire or rod 5 having one end formed into a first coil 5a housed in a container 3 having an exit passage 11 arranged to deform the strip 5 as it emerges from the container 3; the other end of the strip 5 being formed into a second coil housed in a container 4. The containers 3, 4 and/or the strip 5 are arranged so that the force required to extract the strip 5 from the second container 4 is greater than that required to extract the strip 5 from the first container 3 hence the second container 4 dissipates the energy of the peak initial acceleration whilst the first container absorbs the inertia of a load. The rod 5 may be of uniform cross-section steel or, as shown in Fig. 3, of differing cross-section in the two containers 3, 4, coupled at 18. The exit paths from containers 3, 4 may include pins 11 arranged so that the strip 5 emerges via a serpentine path. Unloading aircraft in flight.-A pair of energy absorbing devices 3, 4 may be included in the cable between a cargo-carrying pallet (25) and an extraction hook (26), arranged to engage a steel cable 33 anchored by nylon webbing to the ground. Several pairs of energy absorbing devices 3, 4 may be coupled in parallel between the hook (26) and the pallet (25) depending on the weight of individual pallets.

The starting polymers may be obtained from a polythiodiglycol of formula  where R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP>, R<SP>5</SP>, R<SP>6</SP>, R<SP>7</SP> and R<SP>8</SP> are hydrogen atoms or methyl or methyl or ethyl groups and x is 2 to 5, or from a mixture of such a polythiodiglycol and formaldehyde, by polyetherification (e.g. with sulphuric acid) to obtain a polyether or polyether-polyformal having sulphur atoms in the polymer chains. These polymers have hydroxyl end-groups as terminals which are non-oxidatively curable by sulphur; other suitable terminals are obtained by including in the etherification reaction an alkanol (e.g. 2-ethyl hexanol) to provide ether endgroups, an alkyl carboxylic to provide ester end-groups or a styrene-sulphur adduct to provide styrene polysulphide end-groups. On Reaction with elemental sulphur a copolymer of sulphur and the starting polymer is obtained. Incorporation in elemental sulphur increases the fracture resistance of the sulphur.

Conjugate filaments are made by simultaneously extruding through common orifices at least two solutions of polyvinyl chloride polymers of high syndiotactic index (as defined) and of different shrinkage characteristics (in the extruded and stretched filament). The filaments, which may be wet- or dry-spun, may be alternately heat treated and stretched to produce a permanent and reversible crimp.

Abstract: 1330858 Feeding extruder branch passages WINDMOLLER & HÍLSCHER 28 Oct 1970 [11 Nov 1969] 51224/70 Heading B5A [Also in Division B1] Each branch feed passage 12, 12<SP>1</SP> (or more) leading to a respective extrusion die, is supplied with thermoplastics or non-cross-linked elastomeric material from the main feed passage 11 of an extruder at the outlets of a plurality of laminar channels 4, 4<SP>1</SP> located in parallel planes and which have their inlets in the passage 11 and the outlets of consecutive channels opening into a different branch passage. In the preferred embodiment, the channels 4, 4<SP>1</SP> are milled in the opposed faces of a plurality of plates 3 assembled on rods 7, to form one of the channels 4, 4<SP>1</SP> between each adjacent plate pair, the inlets and outlets of each channel being of blade-like configuration 13 and extending across the full width of the passages 12, 12<SP>1</SP> and 11. This arrangement maintains in the branch passages 12, 12<SP>1</SP> the same transverse temperature distribution as in the passage 11, and provides for some evening out of temperature through the thin walls of the plates between the superimposed portions of the channels 4, 4<SP>1</SP>. Further evening out of temperature of the material may be provided by a heat exchanger which divides the flow into a plurality of parallel laminar flows which are led crosswise past one another. Alternatively, improved evening out of the temperature is obtained if the inlet of each passage 4 or 4<SP>1</SP> extends across only half the width of passage 11, with heat exchange windows of good conductivity separating the superimposed channels 4, 4<SP>1</SP>.

Abstract: 1408848 Arranging articles on conveyers transferring articles between conveyers MET RAMATIC CORP 9 Nov 1973 [27 April 1973 52150/73 Heading B8A Articles 30 on a conveyer belt, are transferred selectively according to their size, or other characteristics, to conveyer belts 36 and 38. In a modification (Fig. 1, not shown), the articles are transferred to selected lanes on the belt 25, instead of being transferred to the belts 36, 38. An endless series of pairs of rails 13 and associated members 14 are carried by endless chains 12 driven at the same speed as the conveyer belt 25. The articles are first correctly spaced by the action of a screw 32. Then they are sensed by a photo-electric beam (not shown). If as the result of the sensing, the article is to be transferred to the belt 36, a gate 24c moves into a position to engage a pin 22 depending from a member 14 sliding on a pair of rails 13. This causes the pin 22 to contact a linear cam 23 and thereby divert the member 14 and so displace the article 30 laterally until it is far enough across the belt to be engaged by a deflector 35 leading to the conveyer 36. Articles 30 not so deflected may (according to the characteristic being sensed) be either deflected in a similar manner on to the conveyer 38, or may be diverted by a guide 45. In a modification (Fig. 1, not shown), the articles are diverted into different lanes on the conveyer 25 instead of being transferred to the conveyers 36, 38.
