Title: Improvements in ornamental illuminating devices
IPC: F21S10/00
Filed: 1943-02-16
Abstract: 563,574. Ornamental lamps. OTIS, C. W. Feb. 16, 1943, No. 2559. [Class 75 (iv)] In an ornamental illuminating device of the type in which vapour bubbles are caused to ascend through a liquid column, a coherent fissured mass is provided on the wall of the housing containing the liquid column in the region where heat is applied to promote vaporization. Suitable substances for use with volatile liquids, such as wood alcohol, ether, or methylenechloride, are sugar, borax and table salt which are introduced into the liquid housing as loose granular substances and are heated sufficiently to melt the powder. On cooling the mass will contain numerous cracks or fissures and will adhere to the liquid housing. Fig. 1 shows an ornamental illuminating device suitable for Christmas tree decoration, comprising a heat and light source 22 mounted in a two-part housing 26 supporting a pellucid tube 48 containing a volatile liquid and fitted with the bubble generating means 66 described in Specification 558,108 above a fissured mass 68 at the bottom of the tube. In another construction the bubble generating means are dispensed with and a larger fissured mass substantially fills the lower portion of the tube. In a third construction shown in Fig. 6, a transparent cylinder 106, only slightly smaller than the inner diameter of the tube, is provided above the fissured mass 100 to cause the smaller bubbles formed beneath it to coalesce into larger bubbles as they ascend through the annular space around it. Glass balls or an inverted cup similar to the cup 66 may be substituted for the cylinder 106 or the fissured mass may have a cylindrical upper portion nearly filling the lower portion of the tube. Alternatively, the lower portion of the tube may have a re-entrant portion of slightly smaller diameter to form an annular space to receive the fissured mass and Fig. 11 shows such a construction in which the re-entrant portion 182 is integral with the upper part of the lamp envelope 180.

Title: Improvements in magnetometers
IPC: G01R33/26
Filed: 1964-01-21
Abstract: 1,019,990. Magnetometers. C. S. F.-COMPAGNIE GENERALE DE TELEGRAPHIE SONS FIL. Jan. 21, 1964 [Jan. 22, 1963], No. 2696/64. Heading G1N. A magnetometer developing an electrical output signal is arranged to provide a measure of both the field intensity and its direction by including means for superimposing on the magnetic field to be measured three alternating fields, of different respective frequencies and small in comparison with the field being measured, directed along three reference axes, and means for detecting a continuous component and the three alternating components in the signal output. The reference axes may be fixed or movable. The invention is described in respect of optical pumping magnetometers stated to be conventional in which the light from a source 2, Fig. 2 detected in a photoelectric cell 3 controls by a feed back loop, including a phase-comparator 5, the frequency of an oscillator 7 which follows up the resonance frequency of cell 1. The fields are applied by coils 101-103 and the four outputs are selected from the output of a discriminator 10 fed also by oscillator 7. In a modification the frequency is determined by a counter and the square of its output is converted to a signal from which the frequencies are selected. A mathematical analysis shows that the signals at the three frequencies are indicative of the directional cosines of the field being measured.

Abstract: 1,102,110. Axial-flow fans. KœHNLE, KOPP & KAUSCH A. G. Jan. 18, 1967 [Feb. 1, 1966], No.2747/67. Heading F1C. In order to reduce the natural frequencies of oscillation of the impeller blades of a large axial-flow fan, e.g. for cooling towers, the stub shaft 7, Fig. 1, of each blade 8 is supported by spring elements 14, 23, 16 and 15, 24, 17 and has a part-spherical portion 9 movably seated in a bearing 10, 11. Each spring element may be entirely of steel or, as shown, comprises a rubber or other elastic member 23 or 24 sandwiched between a pair of metal plates 14, 16 or 15, 17. The spring elements are of greater dimension in the peripheral direction of the impeller than in the axial direction thereof to provide softer springing in the axial direction. Deflection of the blade in the peripheral direction may be limited by stop bars (32, 33), Fig. 2 (not shown). The axis Y of the blade is inclined by angle # to radial axis Z, to produce an equilibrium of moments due to the centrifugal and axial aerodynamic forces exerted on the blade. The portion 10 of bearing 10, 11 is welded to a pair of channel-section carriers, one of which is shown at 4. The carriers are welded to a pair of annular plates 2, 3 connected to a shaft receiving sleeve 1. The plates may be star-shaped with the cut-outs intermediate the blade stubs. The spring elements are connected to a plate 12 welded to the carriers, by bolts 13 which pass through arcuate slots 22 in the plate to permit some angular adjustment of the spring elements and blade. The blade can be angularly adjusted independently of the spring elements after loosening of bolts 21 of a split clamping ring 18, 19 bolted at 20 to the spring elements.

Abstract: 844,926. Transistor pulse generating and regenerating circuits. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Nov. 15, 1956 [Feb. 3, 1956], No. 3446/56. Class 40(6). In a circuit employing a transistor 1 having a current gain greater than unity with an inductor 4 in the base lead, an input pulse applied to the emitter, causes an increase in collector current, followed by a decrease to set up a charge on the capacitance load 12, a pulse from clock source 16 determining the timing of current flow through the load 15. In the quiescent state transistor 1 is biased off and the collector potential A is held at the potential, 12 volts, of battery 10 due to diode 9 conducting. The potential of point B is intermediate between A and earth, -6 volts. Clock pulses of amplitude +6 volts from source 16 carry point B to earth only, so that diode 14 remains non-conducting. An input pulse, applied to the emitter, triggers the transistor circuit, causing the collector and point A to rise to -2 volts so that diode 11 conducts and point B rises to the same potential. Due to the inductor 4, transistor 1 is switched off regeneratively, the potential of point A restoring to -6 volts while diode 11 cuts off. The next clock pulse carries point B positively so that diode 14 conducts to feed a pulse out to the load 15. The pulse from transistor 1 is made longer than a clock pulse to ensure the charging of capacitor 12. Pulse generator. An initiating pulse 2, Fig. 2, is fed through OR circuit 18 to trigger a circuit 17, as in Fig. 1, thereby supplying a clock pulse to load 15. The output is also fed through AND circuit 19 to the input of 18 to prepare the circuit 17 to allow the succeeding clock pulse to pass to the load 15. The circuit is stopped by applying an inhibiting signal from control 20 which closes the AND gate 19 and prevents a signal passing back to the input of circuit 17.

Abstract: 986,203. Making pipes. COMPAGNIE DE SAINT-GOBAIN. Jan. 31, 1962 [Feb. 6, 1961], No. 3630/62. Heading F2P. [Also in Division B5] A thin fibrous felt is impregnated with thermosetting resin, heated to gel the resin and bring it to the plastic polymer state, and then shaped while being heated to bring it at least to the start of the rigid polymer state. Thin felts 2, previously impregnated with thermosetting resin are fed into the pre-heating zone 1 of an oven A. Pulverized thermohardening resin is sprayed on the felt by devices 3, and at the outlet of zone 1 the resin is gelified and in the plastic polymer state. The felt, which may be first covered by talcum powder or fine sand is rolled between a rotating forming mandrel 6 and co-operating rollers 8, the rollers being displaceable radially to the axis of the mandrel to follow variation in rolling of the felt. They may be removed to allow for removal of the mandrel. Injectors 15 for thermohardening resin may be used to further coat the surface of the felt before rolling. The mandrel which may be heated to the temperature of the felt is in the zone 10 of the oven, and at the end of the rolling operation the resin is at the start of the rigid polymer state. The mandrels carrying th rigid sections 14 are then brought into the zone 11 where polymerization of the resin continues, so that at the outlet 12 of the oven it is practically complete. The rigid sections are then removed from the mandrels, for example by cutting along two diametrically opposed generatrices, and the mandrels are returned to the forming position by belt 13. The process is particularly useful for objects formed of glass fibres and in the form of hollow cylinders or rigid sections.
