Abstract: 884,359. Magnetrons. A S S O C I A T E D ELECTRICAL INDUSTRIES Ltd. March 18, 1958 [Dec. 18, 1956], No. 38562/56, Class 39(1) Anode D having a slow-wave circuit surrounds an electrode E coaxial with the anode to provide an annular interaction space subject to the action of an axial magnetic field and an annular beam of electrons is caused to emerge axially from an annular emissive face A into the interaction space on a substantially helical orbit. As the annular beam passes close to the anode circuit, and rotates at the exact synchronous velocity, it is highly effective in initiating oscillations which are further sustained by emission from thermionic or secondary-emitting electrode E, or by another annular beam injected into the other end by a cathode replacing collector plate U. As shown, the cathode A is provided with a heater G and is surrounded by a shield H. Anode extension F and the shaping of the end of electrode E suitably shape the electric field acting on the beam ; further electrodes may be provided in the vicinity of the cathode A for this purpose. According to the Provisional Specification there may be two or more cathodes A of different radii and the magnetic pole-piece may act as a collector. Specification 869,603 is referred to. Reference has been directed by the Comptroller to Specification 807,127.

Title: Improvements in the production of substantially open-cell poly urethane foam
IPC: C08J9/00
Filed: 1964-09-24
Abstract: A process for producing substantially open cell polyurethane foam comprises reacting a diisocyanate with a polyester in the presence of an additive which retards the reaction speed of polyurethane formation and hence the viscosity rise of the reaction mixture relative to the inflation reaction so that the cell walls burst and the material of the burst cell walls is wholly or partially absorbed by the remainder of the polyurethane material, foaming being brought about by water, activators and hydroxyl group containing foam stabilizers are also present.  The additive may be a low molecular weight polyester having an acid number up to 10, a hydroxyl number from 10 to 100 and a viscosity below 200 poises at 25 DEG  C. and/or a solvent of boiling-point below 120 DEG  C.  The preferred polyester additive has acid components the same as the polyester used in the reaction mixture, e.g. adipic, phthalic, or sebacic.  The examples describe variations based on the use of the following recipes: an adipic aciddiethylene glycol-trimethylol propane polyester together with an adipic acid polyester by "Ol Chemie," ref. P103, dibutyl benzylamine, nonylphenolpolyglycol ether, castor oil sulphonate and toluylene-diisocyanate. Trichlorofluoromethane is added as a blowing agent, in Example 2. Other low molecular weight polyesters are included in place of the P103 material and a mixture of methylene chloride and trichlorethylene are illustrated in other examples.

Abstract: 923,984. Rollerway conveyers. MANUFACTURERS EQUIPMENT CO. Ltd. Nov. 10, 1961 [Nov. 12, 1960], No. 38935/60. Class 78 (1). On a rollerway conveyer, articles A, B, C pass successively over rollers 12, each of which is carried by a respective lever 11. The latter is pivoted at 14 and engages through a shock absorber 17, the forward end of an arm 18 which is pivoted at 20 and carries on its upper surface, friction braking material 19. Thus an article A which is brought to rest on the conveyer by a stop 25, engages the leading roller 12 so as to bring the associated braking surface 19 into operative engagement with rollers of the conveyer to the rear of the article A. This brings the next succeeding article B to rest at a predetermined interval from the article A. In a modification (Fig. 4, not shown), the pivot for the arm 18 may be coincident with the pivot for the next succeeding arm 11. In a further modification (Fig. 6, not shown), the shock absorber 17 may be replaced by a cam follower adapted to be engaged by a cam surface carried by the end of the arm 11. In Fig. 8, an arrester wheel 33 is carried by a bell-crank 30 and has an additional arresting action on the passage of each article as it passes on to the rollers overlying each braking surface 19 (except that no arresting wheel 33 is provided in respect of the surface 19 at the extreme forward end of the conveyer). The wheel 33 is retracted on deflection of the next succeeding arm 11 but one, by the action of a stop 37 carried by the arm 11, and which is engageable with an arm 31 of the bell-crank 30.

Abstract: 1,248,158. Doffing and donning. DEERING MILLIKEN RESEARCH CORP. 5 Aug., 1969 [5 Aug., 1968], No. 39236/69. Heading DID. A bobbin holder arrangement, e.g. for grasping full and empty bobbins in a doffing and donning device of a spinning machine comprises means to resiliently mount the holding members. As shown empty bobbin grasping means 18 are mounted on a movable beam 14 and full bobbin grasping means 16 are mounted on a beam 22 carried by beam 14. Both graspers consist of inflatable elastic annuli 52, 82 selectively connected to a source of air pressure. Tube 50 carrying annulus 52 is carried by a U-shaped member 34 on a rod 38 which is supported by a head 30 have bevelled edges and being supported in holes 28 in a bar 24 carried on top of beam 22. A spring is positioned between member 34 and bar 24 so that the grasping device 16 is downwardly urged. If grasping device 16 is incorrectly aligned with the full bobbin onto which it is lowered it can pivot by virtue of spring 46 and the bevelled edges on head 30. If the full bobbin is misaligned when it is lowered onto a receiving peg the head is displaced upwards to contact a wire 108 and operate a stop motion. The empty bobbin grasper 18 is mounted in a similar fashion and is also provided with a stop motion which operates to stop the lowering of the empty bobbin if it is misaligned and becomes jammed on a spindle.

Abstract: 346,023. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. -(Assignees of Lindenblad, N. E. ; Port Jefferson, Long Island, New York, U.S.A.) Dec. 24, 1929, No. 39458. Convention date, Dec. 24, 1928. [Class 40 (v).] A directive short-wave aerial consists of a pair of conductors 2, 4, Fig. 1, connected at 8, 10 across the feed-lines 6 from a high-frequency source, and diverging outwards as shown at 12, 14. The radiators are accordingly connected alternately to the positive and negative poles of the generator, i.e. they are not in parallel. The length of the aerials 2, 4 may be from five to ten wavelengths, and the divergence at the points 12, 14 approximately onefifth of the length. The aerials may diverge in a straight instead of a curved line. To reduce reflection effects, and lateral radiation, the feed-line may be coupled to the aerial through an impedancematching coupling. Alternatively a greater proportion of the input energy may be radiated, with a corresponding decrease in reflection, by using a number of antenna sections which are successively diverging and converging. As shown in Fig. 3, a diverging aerial 22 is coupled through a phasereversing link comprising two helical conductors 26, 28 to a converging aerial section 24, coupled in turn at 32, 34 to a diverging section 30. In Fig. 5 a transmitter 20 is coupled through a feed-line 24 to a diverging section 22, which is joined through non-radiating, phase-reversing elements 40, 42 to a converging section 24, followed by a diverging section 30. A number of such aerials mav be arranged to give a broadside directional effect, the radiation taking place along the axis of each pair of conductors.

Abstract: An adhesive is produced by dispersing discrete particles of cyclohexanone resin or maleic anhydride-rosin adduct together with discrete particles of a plasticizer, e.g. dicyclohexyl phthalate, in a volatile liquid non-solvent for both constituents.  The discrete particles are obtained by precipitation from a solvent, e.g. by pouring a solution of the resin in a water-miscible organic solvent into a larger, e.g. 10 times, volume of constantly stirred water below 25 DEG C., e.g. at 8 DEG C. (or vice versa), the solution or water preferably containing a wetting agent; a separate stream of a plasticizer solution may be added to the same water or precipitated separately.  A polybutyl methacrylate (or other synthetic resin) emulsion and a small amount of monoethanolamine oleate are then preferably incorporated in the dispersion which is deposited as a film on a substrate, the volatile solvent being evaporated at low temperature to leave a delayed action heat-seal adhesive layer.
