Abstract: 399,779. Magnets ; electromagnets. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Jan. 6, 1932, No. 440. Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 25, 1932.] Class 35.] Leakage flux is reduced in a permanent or electromagnet, more particularly for loud-speakers, microphones, gramophone pickups, measuring-instruments, &c. and comprising one or more magnetically active air gaps, by shaping the poles which form jointly an air gap so that the angles which the corresponding leakage surfaces of each gap form with each other are substantially equal. The expression " corresponding leakage surfaces " is defined in the Specification as meaning the pole surfaces which adjoin the air gap and between which pass lines of force which do not pass through the air gap. Fig: 2 shows a construction of magnet comprising a steel body portion 1, an axially fixed cylindrical soft iron stud 2 and an annular soft iron polepiece 3, the cylindrical surface 4 of which forms with a portion of the stud 2 an annular air gap 5. According to the invention, the angle formed between the upper surface 6 of the ring 3 and the upper side 8 of the stud 2 is substantially equal to that formed between the lower surface 7 of ring 3 and the lateral surface 9 of stud 2. Fig. 3 shows a modified construction in which the advantage of the equal angles is enhanced, the height of the gap being made smaller than the thickness 10 of the steel of the lateral wall of the magnet body 1.

Filed: 1939-01-11
Abstract: 523,628. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., COLLYER, J. E., and SMART, N. C. Jan. 11, 1939, No. 927. [Class 40 (i)] [Also in Group XXXIX] In a system in which high voltage signals are transmitted from a control station over a line normally used for telephony, the telephone instrument at a substation is automatically disconnected before and during signalling operations. The line may be the pilot line of an electric supply system and signals may be transferred from it to the supply system for controlling street lamps. As shown, the telephone instrument 23 is normally connected to line by relay A energized by battery feed overwindings A at the distant end, 11. being the. telephone instrument thereon. When switch 37 is thrown over to the A.C. signalling generator 38, A falls back and the signal voltage is gradually increased by means of potentiometer 15. Relay B pulls up before the voltage is dangerously high, opens further points in the telephone circuit and switches the line over to transformer 32 which superimposes the signal on street feeder 27-29 to operate relays such as C' which switch on lamps 39. Other relays such as C connected to the same or different conductors may be operated simultaneously or they may be operated at different times by different signalling frequencies. Relay C may be of the type described in Specification 491,980, [Group XXXVII], so that it responds to a different frequency to switch off the lamps. As a further precaution, a manually operated switch must be - operated before the receiver can be removed so that the user is warned by the tone if present.

Abstract: Coating, esp. by printing with a powder or paste, is carried out with polyethylene powder (I) having a different polymer (II) adhering to the surface of the particles. Pref. (I) is LDPE powder. (II) is a polyamide, polyurethane, polyester, polyacrylate, polyvinyl halide, polyvinyl acetate, polyether and/or polyalcohol. A plasticiser (bisphenol A) may be added. The amt. of (II) is 0.5-25 (1-10) wt.% w.r.t. (I). (II) is applied as a soln. or dispersion and dried. A double dot coating may be used, the coated (I) providing a barrier layer preventing the top layer flowing into the interfacing. This barrier layer consists of (I) contg. 0.5-10% (II), whilst the top coat consists of a hot melt adhesive powder of copolyamide (m.pt. 80-130 deg.C) or copolyester (m.pt. 115-140 deg.C). (I) has a particle size distribution of 0-200 (9-80) microns. The breaking load of the (II)-coated (I) at room temp. is (min. 25, pref. min. 50%) lower than that of uncoated (I). The technique is esp. useful for coating woven, knitted and nonwoven textile, real and artificial leather and foams. The surface properties of (II)-coated (I) are about the same as those of (II) powder, allowing (I) to be applied in the same way as other more costly hot melt adhesive powders, e.g. (co)polyamides and (co)polyesters.
