Title: Improvements in or relating to apparatus for the manufacture of sweets
IPC: A23G3/24
Filed: 1960-10-04
Abstract: 918,258. Coating confectioners' goods. WARREN, C. J. L., and MILROSS, J. W. Oct. 20, 1961 [Oct. 4, 1960], No. 34030/60. Class 28 (1). Edible centres, e.g. nuts, are coated with toffee by impaling on spikes 16 (Fig. 1) on a number of spaced support bars 15 fixed to a conveyer which is guided to partly immerse the spikes in hot toffee and thence upwards towards a delivery station, stripper means being associated with the spikes and operable when the supports reach the delivery station. The conveyer which consists of two endless chains 4 and 5 (Figs. 1 and 3) is given an intermittent unidirectional movement by a sprocket wheel 6 acuated, via a rod 26, and a ratchet and pawl 27, by an eccentric 25 driven by a shaft 24 from an electric motor (not shown). Another eccentric 36 is also driven by the shaft 24 and actuates, through rods 35 and 40 and bell crank levers 33 and 38, arms 37 and 41 respectively. As each support bar 15 reaches the position opposite the free end of the arm 37 (Fig. 1) the arm engages one of two rods 23 (Figs. 3, 4 and 5) mounted on a flanged plate 22 and moves the plate 22 outwards away from its associated support bar 15 against tension springs 45 so causing the toffee-coated nuts to take up the position shown in Fig. 5. In a similar manner when the support bars reach the position opposite the free end of the arm 41, the plate 22 is caused to move by the arm 41 to a sufficient extent to strip the coated nuts from the spikes 16 (Fig. 6, not shown), the nuts then falling into the cups 47 of another conveyer 49. Each support bar 15 carries a slotted rack bar 19 (Fig. 3), the teeth of which engage with toothed pinions 18 on the spikes 16. The spikes 16 are caused to rotate through 180 degrees in either direction as the rack bar 19 is moved alternately from side to side by the action of a plurality of cams 30, 31 extending along one side of the vertical part of the conveyer (Fig. 2, not shown). The container 42 is raised by means of a pneumatic or hydraulic ram 48, under the control of a float valve (not shown) as the level of the toffee falls.

Title: Improvements in or relating to antenna systems

Abstract: 1,012,888. Aerials. L. ROHDE, and H. SCHWARZ, [trading as ROHDE & SCHWARZ]. Sept. 6, 1962 [Sept. 6, 1961; Nov. 18, 1961], No. 34140/62. Heading H4A. An aerial array comprises a plurality of plane surface radiating elements 13, 14 symmetrically disposed in alternating sequence on the upper and lower surfaces of a dielectric support sheet 4 whose permittivity is substantially equal to that of free space. The support 4 is made of polystyrene foam and has the shape of a flat bottomed trough, the surface of the dielectric material 4 being hardened by a layer of synthetic material which closes the pores of the surface. The edges of the end of the trough are chamfered to co-operate with a similarly shaped reflector R which is parallel to the surface radiators and the conductive portions of the aerial system attached to the side of the support 4 facing the reflector R may be earthed by metallic supports located at the voltage modes. A protective covering 9 mounted around and spaced apart from the base of the support is provided to reduce the effect of ice formation and an earthed metal strip B, Figs. 2A and 2B, is mounted on the covering 9 parallel to the feeders 15, 16, 18, 19 interconnecting the radiating elements for protection against lightning. The radiating elements (which, as shown, are triangular but which may be rhombic, semicircular or Indian club-shaped) and their feeders are mounted in recesses 11, 12 formed in the upper and lower surfaces of the support. As shown, four pairs of elements (arranged as dipole groups) are symmetrically disposed with respect to the central feed point 17, each pair of elements being connected in parallel with the remaining pairs through strip feeders 15, 16, 18, 19, the feeders 18, 19 being wider than the feeders 15, 16 to effect matching. The elements and their feeders may be stamped from metal foil and attached to the supports by gluing or by means of flaps cut from the elements (Fig. 4, not shown) and pressed through the support sheet and then bent back or twisted (Fig. 3, not shown). Alternatively the elements and feeders may first be formed on thin printed circuit panels by etching or other known methods and these panels are then attached to the support by any of the methods referred to above. In a further embodiment (not shown) small holes are formed in the elements and their feeders which are held on the support by plugs of the support material oozing through the holes during the moulding process. Larger apertures 20, 21 formed in the moulding material are provided to facilitate connection of the central feeder point 17 to a printed circuit coupling unit (not shown) mounted on an internal stiffening rib of the support 4.

Title: Solar energy receiving apparatus
IPC: F24S10/30
Filed: 1977-08-18
Abstract: The collector element has a transparent tubular sheath (1) which is sealed by a hood (2) made from a thermally conductive material, in order to form a low-pressure evaporating and condensing system. A wick (3) made from a metallic wire mesh having a radiation-absorbing coating is inserted inside the tubular sheath (1). The system thus formed is partly filled with a heat-transfer medium (4) in such a way that in an evaporating region bounded by the transparent sheath (1) the medium is evaporated by irradiated heat (R) and rises to a condensation region in the hood (2) where it condenses with the release of heat and is guided back to the evaporating region by gravity and/or capillary action of the wick (3). The heat is led off for use from the hood (2) by means of a further heat-transport medium. Such a solar collector element has a high efficiency. <IMAGE>

Abstract: 1359947 Ethylene-but-1-ene copolymers NATIONAL PETRO-CHEMICALS CORP 25 July 1972 [27 July 1971] 34808/72 Heading C3P [Also in Division C5] A polymerization process comprises copolymerizing ethylene and but-1-ene in a liquid diluent in a polymerization reactor, recovering the copolymer and a recycle mixture containing diluent and unreacted but-1-ene, isomerizing some of the but-1-ene in the recycle mixture to but-2-ene and returning the resulting mixture to the polymerization reactor and employing it therein in the formation of an ethylene polymer substantially zero but-1-ene content or of an ethylene-but-1-ene copolymer having a lower but-1-ene content. The polymerization may be carried out within a smooth continuous path reaction zone at temperatures and pressures such that substantially all of the diluent is in the liquid phase and the polymers produced are in the form of solid particles slurried therein. The but-1-ene may be isomerized in the presence of an isomerization catalyst (e.g. molecular sieves or alumina and oxides of Si, B, Zr or Th). The but-1-ene may be formed in situ by the dimerization of ethylene using, e.g. T 1  tetraoctylate or tetrahexylate. In the example the polymerization catalyst is a chloride of T 1  supported on MgO and triethylaluminium, the diluent is isobutane and hydrogen is fed to the polymerization reactor.

A method for manufacturing a cord or like product by plying threads or yarns is characterised in that the cord is subjected at or shortly after the point of cording and before a draw-off device to a combination of tension and heat treatment to eliminate the irregularities in the internal stresses in the cord. In the arrangement of apparatus shown for performing this method yarn 1 from a package 2 is tensioned at 8 and is then ballooned by means of a false twist device 3 around a second package 5. Yarn 7 from this second package is tensioned at 9 and is plied with the yarn 1 at 6. The cord so formed passes through a guide eye 10 and a tensioning device 11 to tube 12 which is steam heated and thence by means of rollers 13 to a take-up device (not shown). The tube 12 may alternatively be heated by hot air and instead of the tensioning device 11 a positive forwarding device driven at a slower speed than the rollers 13 may be substituted.
