Title: Improvements in the binding up of cores such as cable forms, toroidal coils, coil heads and the like
Inventor: KATZER HUGO
IPC: H02K15/00
Filed: 1964-02-18
Abstract: 1,030,776. Covering cores by winding. ELEKTROMAT VEB. Feb. 18, 1964, No. 6631/64. Heading B8G. The invention relates to a method and apparatus whereby a reciprocating needle can be used to form a binding around a core. In Fig. 3 (not shown), the needle 3 is above a stator member 1 from which a winding end 5 projects. Before the needle 3 descends a catcher 6 moves from right-to-left, Fig. 4 (not shown), and thereafter the needle 3 descends to deliver a loop of upper thread 4 below the winding end 5, Fig. 5. The catcher 6 then moves to the right, Fig. 6 (not shown), pulling the loop with it and presenting the loop to a mantle 8 resolving round a bobbin holder 7 carrying a lower thread supply 10. The mantle 8 carries the loop with it and interlinks it with the lower thread 10, Fig. 7 (not shown), whereafter the needle 3 returns to its upper position, Fig. 7. The needle then moves over to the other side of the winding end 5, Fig. 8 (not shown), and the catcher 6 again moves to the left. In Fig. 9 (not shown), the needle 3 has descended carrying with it a loop that is about to be caught by the catcher 6 as it moves back to the left. In Fig. 10 (not shown), the end catcher 6 has presented the loop to the mantle 8 that is then revolved to cause the loop to interlink with the lower thread 11. The needle 3 then rises, Fig. 11 (not shown), and returns to the left-hand side of the winding end 5, Fig. 12 (not shown). The above steps are then repeated, the stator 1 being indexed about its axis by a small amount each time the sequence illustrated in Figs. 3 to 12 has been completed.

Abstract: 710,334. Moulding processes ; patterns ; cores ; extracting castings. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 9, 1951 [March 17, 1950], No. 6759/50. Class 83 (1). [Also in Group V] In a method of making a cored precision casting by means of a refractory core embedded in an expendable pattern of readily fusible material, the core extends through the length of a split die used for moulding the pattern and is accurately located by separable parts which are removed from the ends of the core when the pattern is removed from the die. The core is preferably of fused silica, commercially available in the form of tubes and after casting is dissolved from the metal by caustic soda. Other suitable materials include porcelain, sillimanite, alumina, zircon, magnesia, carbon or a refractory metal. The invention is described as applied to the casting of a turbine blade having internal passages for cooling fluid. A wax pattern is formed in a die comprising an upper part 2 and a lower part 1 having detachable end plates 4, 7 drilled to receive silica tubes 9 and inserts 10 slotted to receive the ends of silica strips 12 to form passages through the root portion 13a of the blade 13. End plates 4, 7 are secured by pegs 6, 8 and the die parts 1, 2 are aligned by dowels 3. Wax is injected into the die through openings in the plate 7. The removal of the silica cores from the cast metal is preferably carried out in molten caustic-soda under a pressure of about 110 lbs. per square inch. Instead of wax other expendable material such as frozen mercury or a very low melting point alloy may be used for the pattern.

Abstract: 125,098. Smith, J. G. May 12, 1916. Drawings to Specification. Submarines, systems for damaging and destroying.-Consists in a method of attacking submarines and other submerged objects and comprises the use in succession of (1) a shell adapted to produce an upheaval or other disturbance in the surface of the water in front of the submerged object, and (2) an armour-piercing or other ordinary shell timed to enter the water at the point of disturbance before the water has returned to the normal condition. Deflection of the ordinary shell from its normal trajectory on entering the water is thus prevented. The two projectiles may be fired from a gun having two barrels or from separate guns fired with a measured interval between the shots; or the desired interval between the arrival of the shells may be obtained by discharging both together, using different propellant charges or using a leading or special shell which is lighter than the -other.

Abstract: A continuous process for the preparation of high molecular weight linear polyamides by the condensation polymerization of a polymethylene diammonium salt of an aliphatic alpha, omega-dicarboxylic acid containing from 8 to 24 carbon atoms or an omega amino carboxylic acid containing from 6 to 12 carbon atoms, comprises pumping an aqueous solution of the monomer into the entry end of a long tube having an internal diameter not greater than 2,5 cm. heated to polymerization temperature so that the material polymerizes as it passes through the tube, wherein the pressure is at least 14 atmospheres at the entry end of the tube, continuously decreases along the tube and falls to substantially atmospheric or subatmospheric pressure at the exit end of said tube but always permits the evolution of steam which is derived from the aqueous solution or the water of condensation, and at any point in the tube has a value constituting a continuous monotonic single-value function of the distance of said point along the tube, the rate of passage of the polymerizing material through the tube being such that at least 90% of the total theoretical water of chemical condensation is evolved during said passage, and optionally further heating the material issuing from the exit end of the tube to complete the polymerization of the polyamide. Specified monomers are hexamethylene diammonium adipate, hexamethylene diammonium sebacate, octamethylene diammonium adipate, decamethylene diammonium adipate, pentamethylene diammonium sebacate, dodecamethylene diammonium adipate, omega-aminocaproic acid and omega-amino undecanoic acid.  The examples describe the preparation of polyamides from:-(1), (6), (7) and (8) hexamethylene diammonium adipate, and hexamethylene diamine; (2) and (3) omega-aminocaproic acid; (4) hexamethylene diammonium adipate, hexamethylene diamine and acetic acid in the presence of titanium dioxide; (5) hexamethylene diammonium adipate and hexamethylene diamine in the presence of elementary iodine and cupric acetate; (9) to (12) hexamethylene diammonium adipate, hexamethylene diamine and acetic acid and (13) hexamethylene diammonium adipate, hexamethylene diamine and acetic acid in the presence of carbon black.  In a modification of the process, the material issuing from the exit end of the tube is heated in one or more vessels and the resultant polyamide melt spun into filaments, fibres or films.

[Class 40 (iv)] [Also in Group XL] A system for secret telephony comprises a cathode - ray tube R, Fig. 2, provided with a mosaic electrode S and with two electron guns each of which comprises an indirectly-heated cathode 7, modulating electrode 6 and anode 5. Anodes 4 collect the secondary electrons on the respective sides of the mosaic. The potentials for the various electrodes are obtained through resistances 9 .. 12 from a potentiometer 8, a point of which, together with the common electrode of the mosaic S, is earthed. The mosaic S, Fig. 3, comprises two elliptical or circular parts which are fitted with insulated elements emitting secondary electrons, and are joined by insulating members 22. Speech signals from a microphone 14 are amplified at 15 and applied across a resistance 13 so as to be superposed on the potential of a control electrode 6. Charges are formed by the controlled beam on the electrodes of the mosaic which is subsequently scanned by the beam 20 of constant intensity. A voltage which varies in dependence upon the original speech signals will he produced across the resistance 11 and may be amplified and transmitted. The rays may be adapted to scan the mosaic in opposite directions, preferably crossing at the insulating members 22, so that an inversion of the speech signal is obtained. Further, the rays may be adapted to pass rapidly over the members 22 so that only supersonic interruption occurs. The rays are deflected to scan the mosaic by electrostatic means or by pairs of magnetic members 18, 19 which are connected to independent generators 16, 17. The above arrangement can be used in telegraph systems.
