Abstract: 522,552. Cellulose derivative and synthetic resin compositions and articles made therefrom. MERGIER, P. L., and LEROY, P. E. Dec. 15, 1938, No. 36600. Convention date, Nov. 22, 1938. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 21, 1939] [Classes 2 (ii) and 2 (iii)] A composition, suitable for moulding articles such as statues, fancy goods, household furniture, canoes, lighting apparatus, advertising objects, luminous sign boards, architectural elements, or hollow-ware, or for lining walls or other objects, consists of two contacting phases, the first comprising a concentrated solution in a volatile solvent of a colloidal material such as a cellulose ester or a synthetic resin, and the second consisting of grains of the same colloidal material, the phases being present in such proportions that the first phase readily gels without syneresis occurring. When the two phases are brought together the grains absorb part of the volatile solvent and become peptized on the surface and the solution turns to a thick jelly. The total weight of cellulose derivative or synthetic resin is at least equal to the weight of volatile solvent employed. Plaster or other moulds may be used and to avoid adhesion they may be coated internally with a thin layer of gelatine. In an example, dry grains of cellulose acetate are added to a viscous solution of cellulose acetate in acetone. The mixture is poured into a plaster mould. The mass rapidly sets to a gel and the volatile solvent is allowed to evaporate. Colouring or filling materials may be incorporated in the compositions. The Specification as open to inspection under Sect. 91 comprises also the production and use of compositions in which the added grains are of colloidal material other than that employed as solute, in the solution phase. Degraded cellulose ethers may be used. This subjectmatter does not appear in the Specification as accepted.

Filed: 1972-08-07
Abstract: 1356515 Zone melting; sonic vibrations SIEMENS AG 7 Aug 1972 [27 Aug 1971 2 Dec 1971] 36760/72 Heading B1S In the production of a monocrystalline semiconductor rod by non-crucible zone melting the rod is subjected to sonic vibrations in the axial direction during zone melting. If desired the axis of vibration and the axis of the rod may differ by not more than 10 degrees from the vertical. The sonic vibrations may be transmitted to the rod by one of the rod holders or via a coupling medium connected between the rod and rod holder. The sound generator may be a cooled magnetostrictive or piezoelectric sound generator. The coupling material may be a metal or metal alloy, e.g. lead-tin alloy or an attenuating material such as polytetrafluoroethylene admixed with an epoxy resin. The sonic vibrations may be transferred to the rod holder by a head of liquid or by means of a tube of light metal such as aluminium. As shown in Fig. 1, an upper rod holder 2 supports the end of a silicon rod 1, and is coupled via a spring bellows seal 3 to a head of liquid 4, e.g. silicone oil, located in a tube 5 which passes through a seal 7 in the upper wall 6 of the chamber in which the zone melting process takes place. At the upper end of the tube 5, another spring bellows seal 8 provides an outer seal for the head of liquid 4 and simulataneously enables sonic vibrations produced by excitation of a magnetic coil 9 to be transferred to the liquid and to act in an axial direction on the starting rod 1, in the manner indicated by double arrow 15.

Abstract: 1,025,341. Inverting. GENERAL ELECTRIC CO. Sept. 24, 1963 [Oct. 23, 1962], No. 37456/63. Heading H2F. In an inverter circuit comprising a bridge of controlled rectifiers SCR1... SR4 supplying a load 6 with pulses of current in alternate directions and in which a control signal 3 is fed to the rectifiers SCR1 and SCR2 directly and is fed to the rectifiers SCR3, SCR4 after a phase shift effected by a circuit 1 (through a transformer 2 and multivibrator 4) so that the output depends on the degree of phase shift and is zero when the phase shift is zero, an overload protection arrangement includes means for reducing the phase shift to zero on overload. The phase shifting control circuit 1 is disclosed in Fig. 3 (not shown), and comprises a phase-shifting saturable reactor 14 in series with a shaping circuit 13, normal phase-shifting being effected by a control winding 19, 21. As shown, the saturable reactor includes two parallel primary windings 15, 16 and two series connected open-circuited secondary windings, but an arrangement in which there are only primary windings is disclosed (Fig. 5 not shown). Protection is effected by short-circuiting the ports a, b, thereby eliminating the phase shifting, when overload is sensed at 7 and applied to a circuit 8. Various circuits are disclosed for effecting the short circuit; in one set (Figs. 3B, 3C, 30, 5 and 6, not shown), when the circuit 8 is a solenoid, the short circuiting depends on the operation of reed switches; in another set (Figs. 4, 8 and 9, not shown), the circuit 8 is a pulse-producing circuit, and the short circuit depends on the firing of controlled rectifiers by these pulses. The device 7 may be a resistor or a current transformer.

Title: Improvements in or relating to wave change switches
Inventor: RALPH WILLIAM FREDERICK
IPC: H01H15/10
Filed: 1957-12-02
Abstract: 900,569. Mechanical switches, without quick action; switches held set and freed mechanically. PLESSEY CO. Ltd. Feb. 4, 1959 [Dec. 2, 1957], No. 37516/57. Class 38 (5). [Also in Group XL (c)] The shaft 2 of a variable capacitor or other tuning element operates a switch at the limits of its rotation. Shaft 2 carries a disc 3 freely rotatable thereon but biased by a spring 10 to hold an arm 4 projecting from disc 3 against a stop 8. A disc 11 secured to the shaft 2 has a lug 12 which co-operates with abutments 13, 14 on the disc 3. When shaft 2 is turned such that the lug 12 engages abutment 13, in which position two notches 18 in the edge of disc 11 are aligned with notches 17 in the edge of disc 3, further movement of shaft 2 rotates the disc 3 against the action of spring 10 until projection 4 engages a stop 9. The aligned notches 17 and 18 are now in register with the ends 16 of a locating spring 15 which retains projection 4 with a contact 5 thereon bridging fixed contacts 6 and 7. The slightest return movement of shaft 2 causes the ends 16 of spring 15 to ride up on the periphery of disc 11 and thereby disengage the notches 17 whereupon spring 10 causes the disc 3 to rotate until projection 4 again engages stop 8 as shown. Abutment 14 serves merely to limit rotation of shaft 2 when the lug 12 engages therewith. In another embodiment (Fig. 3, not shown), the spring 10 is omitted, the disc 11 is of smaller radius so as not to engage the locating spring, and additional notches are provided in the disc 3 such that it is retained in either end position until moved positively by rotation of shaft 2. In a third embodiment (Fig. 4), a screw 45 engages a respective one of lugs 43 and 44 to rotate a member 42 having two arms 52 and 53 which reciprocate a rectilinearly slidable member 54 carrying contacts 56 and 57. Location in the two end positions is provided by a spring 49 causing a ball 48 to co-operate with a hump 51 and urge arm 52 or 53 respectively against a stop 46. Specification 847,406 is referred to.
