Title: Process for the preparation of laminated structures consisting of polystyrene and polyester
IPC: B32B27/00
Filed: 1961-03-30
Abstract: A process for the production of a laminated structure comprises coating at least one surface of a polystyrene foam sheet with a layer of a copolymerizable mixture containing an unsaturated polyester resin, vinyl acetate and a small proportion of an aliphatic or an aromatic aldehyde and heating the resultant assembly not in excess of 70 DEG C. to copolymerize the mixture.  The polyester resin may be derived by the condensation of fumaric acid, maleic acid or itaconic acid with ethylene or propylene glycol.  A part of said acids may be replaced by adipic, phthalic or chlorendic acid.  The aldehydes specified are acetaldehyde, propionaldehyde, butyraldehyde, hexanal, n-heptanal and benzaldehyde.  Methylethyl ketone, methyl and butyl phthalate and cobalt octoate may be present in the coating mixture. A reinforcing material, such as glass fibres, may be incorporated in the mixture or may be applied between two coatings and then a plate of glass or metal coated with a mould release agent, may be applied on the top coating of mixture.ALSO:A copolymerizable mixture for coating polystyrene foam (see Group III) comprises an unsaturated polyester resin, vinyl acetate and a small proportion (e.g. 1 to 5%) of an aliphatic or aromatic aldehyde.

Title: Improvements in an injector
IPC: F04F5/46
Filed: 1929-04-16
Abstract: 331,299. Dehn, F. B., (Penberthy Injector Co.). April 16, 1929. Giffard injectors; overflow arrangements.-An injector has a sliding delivery tube which normally provides a large relief space between it and the suction tube which space is reduced on the establishment of the jet. Valves may be arranged between the overflow chamber and the combining chamber and the overflow chamber and the delivery chamber. A single-tube injector has a water and steam space A, a combining-chamber B, a delivery chamber G and an overflow chamber D. Steam and water inlets 2, 3 respectively, a boiler discharge outlet 4, and an overflow outlet 5 are arranged as shown. A steam jet 6 projects into the chamber A. The suction jet 8 is conical, has a flared end 9, and enters the end of a bushing 20 mounted above a housing 11 containing a sliding-delivery tube 22 provided with converging, cylindrical, and diverging portions, lateral spill holes 26, and a flange 27 which seats on the end of the housing when the tube is raised. Lateral openings 28 and longitudinal grooves permit water to escape to the overflow. A lateral projection 30 in the casting 1 is provided with a valve-controlled aperture leading to the chamber D and an outlet 41, and carries a nipple 35 with a second valve-controlled aperture leading to a passage 40 and the chamber C. In a modification of this construction the double outlet valves are replaced by a valve carried on a pivoted arm, the chambers D, C are not connected. In a further modification a flange on the delivery tube engages a seat on the housing 11 when raised and closes the communication between chambers B and C, and apertures are formed in the casing 11 to connect chambers B, C in the down-position of the tube. No spill openings are provided. In operation steam from jet 6 and water from inlet 3 pass through the tube 8 into the member 20 which is raised, the mixture passes to the chamber B and the steam is condensed. The pressure produced opens the outlet valves and the mixture escapes until the jet is established. The jet passes on to the chamber C the pressure in which acts on the outer valve 'through passage 40. When the jet is established, the pressure in chamber B falls. the valve 33 closes; the pressure in chamber C rises and closes the outer valve, and raises the tube 22 to cause the flange 27 to seat in the housing 11. The spill holes 26 receive the discharge through the tube due to internal pressure until the pressure is balanced in the housing 11. In the construction shown in Fig. 5, the jet 64 is arranged between steam jet E and water chamber F. The delivery tube 67 carries a collar 69 which engages a partition 70 when forced down by the pressure produced in chamber H. Valves 74, 77 are arranged in connexion with the overflow chamber I and are simultaneously opened and closed. The delivery tube may be made in sections, one or more being slidable.

Title: Improvements relating to electric coils with formers made from ceramic materials for use at high frequencies
IPC: H01F21/02
Filed: 1951-05-22
Abstract: 715,475. Radio apparatus. SIEMENS-SCHUCKERTWERKE AKT.-GES. May 22, 1951 [Oct. 1, 1948; Oct. 1, 1948; Oct. 1, 1948], No. 11992/51. Class 40 (5). [Also in Group XXXV] An electric coil for H.F. use has a conductive winding 2 or 17 supported on a ceramic former 1 or 14 having a dielectric constant of at least 30 and being of titanium dioxide or a substance containing titanium dioxide. The winding is formed by metallizing, by fusion of a noble metal. the bottom and sides of a groove 3 or 16 in the former surface, the groove following a helical or spiral path depending upon whether the former is cylindrical or is disc-shaped respectively. The groove may be continued on the inside of the cylinder or on the other side of the disc and the two windings connected in parallel. The desired self-capacity of the coil is obtained by selection of the pitch, width and depth of the grooves, and in cylindrical formers, of the wall thickness (including the use of solid cylinders); alternatively, the cylinder bore may be partially or wholly metallized. Adjustment of the coil's selfcapacity may be provided by the selected introduction into the field of a cylindrical coil of one or two additional ceramic bodies 10, 11 of dielectric constant of at least 30 and which may be partly or wholly metallized, such bodies being disposed inside or outside, or both, of the coil; in spiral coils such bodies 18 are discs disposed on one or both sides of the coil, or where there are tow coils, as shown, a disc may be disposed between the two. The winding alternatively may be fused on to the external screw thread of a cylindrical former, Fig. 7 (not shown), over which an internally threaded additional body is ad'ustably positioned. To obtain a coil whose temperature-frequency characteristic is adjustable, the said additional bodies which are selectively introduced into the field of the coil are made of a material having an opposite temperature coefficient of capacity from the coil former; and a compensating body of opposite capacity-temperature characteristic from the additional body may be so attached to the latter as to be withdrawn from the coil as the additional body is introduced into it.
