Title: Variable directional electric wave generating device
IPC: H01Q3/44
Filed: 1926-11-01
Abstract: 263,752. Yagi, H. Dec. 29, 1925, [Convention date]. Directive signalling. -A central energized aerial 1, Fig. 1, is arranged in combination with concentric reflecting and "directing" conductors, so that directional transmission can be effected in different directions at will, or may form a continually rotating beam. Each of the auxiliary conductors is formed in two parts a, b, as shown in Fig. 4. When the two parts are connected, the effective height of each conductor is greater than half the operative wavelength, in which case the conductor functions as a reflector. When disconnected, the effective part a is less than half the signal wavelength, and the conductor functions as a " director " or re-transmitter to assist propagation along its plane and that of the main aerial. In Fig. 1, the reflecting conductors are shown as open circles, and the directing conductors are shaded, the path of the beam being shown by the arrow. The concentric circles of conductors may be spaced apart by distances varying from one quarter to three quarters the signal wavelengths. The conversion of each conductor from reflector to director may be effected by any suitable means for connecting or disconnecting the parts a, b.

Filed: 1929-09-10
Abstract: 319,357. Bates International Bag Co., (Assignees of Hoppe, E.). Sept. 22, 1928, [Convention date]. Paper and like bags.-In a multi-wall paper bag, the edges of the individual layers are staggered inwardly as at 11, 20, 18 at the inside of one flat side and outwardly as at 10, 20, 16 at the other one so that when the layers are folded inwardly along the lines 21, 22 the edges of opposite flat sides of each individual layer lie one upon the other and are secured simultaneously together. In making the bag, the paper layers 1, 2, 3 are laid upon each other as in Fig. 3 and are folded inwards along the lines 4, 6 and 7, 9 to form side folds, and the edges of the layers are joined to form a tube, single bag lengths being then severed from the tube. Specification 343,447, [Group XVII], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that, to effect the severance, the paper layers are treated separately before folding by passing them through pairs of .rollers carrying pins and slitting knives. The outer layer is perforated along the lines 10, 11, 12 and is slit longitudinally at 14, 15; the central layer is perforated along a straight edge 20, and the inner layer is perforated along the lines 16, 18, 19 and is severed at 17, 13. After the layers have been folded, they pass between uniformly rotating gripping rollers to a second pair of intermittently acting rollers which rotate at a higher speed than the gripping rollers. As the perforated portions pass the gripping rollers, the second pair of rollers seize the tube and pull the protruding bag length away from the remainder of the tube. This subject-matter does not appear in the Specification as accepted.

Title: An electric hot plate unit
Inventor: LEDERMANN HUGO
IPC: F24C15/10
Filed: 1958-08-28
Abstract: 862,107. Electric hot plates. SURSEEWERKE A. G. Aug. 28, 1958, No. 27607/58. Classes 39 (3) and 126 An electric hot plate 1 is surrounded by a plate 2 and is held by a ring 3 which is pressed against a flange 5 of the plate 2 by a recessed ring 4 of high thermal conductivity. Screws and washers 6, 7 secure the ring 4 and, when the hot plate is unheated, an annular air 'gap between the ring 4 and the hot plate is maintained by springs 8. The ring 3 is preferably of a material of poor thermal conductivity and prevents spillage between the hot plate and the ring 4. When the hot plate heater is first energised, the air gap thermally insulates the ring 4 from the hot plate and the latter heats up rapidly. On reaching a sufficiently high temperature, the hot plate will have expanded so that it makes contact with the ring 4 and heat passes into this ring and into the plate 2. The ring now expands and heat contact with hot plate is broken. If the hot plate is used, e.g. by placing a cooking utensil on it, the hot plate temperature falls and contact with the ring 4 is broken or reduced thus allowing more heat to pass to the utensil. When heat is lost by the plate 2 to a utensil placed on it, contact of the ring 4 with the hot plate is improved and heat transmitted to the plate 2 via the ring 4 is increased. Two or more hot plates may be provided U-shaped leaf springs may be used instead of the springs 8, and the springs may be located between the plate 2 and the hot plate. Pressure elements which pass through apertures in the ring 4 may be used with the springs. A further alternative comprises a corrugated resilient ring inserted between the hot plate and the ring 4.

Title: Improvements in or relating to sodium vapour electric discharge lamps
Inventor: RIGDEN SYDNEY ALFRED RICHARD
IPC: H01J61/33
Filed: 1954-09-27
Abstract: 815,893. Discharge lamps. GENERAL ELECTRIC CO. Ltd. Sept 19, 1955 [Sept. 27, 1954], No. 27903/54. Class 39(1). A low pressure sodium vapour discharge lamp having a tubular straight or U-shaped envelope 1 mounted or arranged to be mounted within a heat-conserving single or double-walled outer jacket 3 and consisting of or including one or more axially straight parts between the electrodes 2 has at least one straight part formed with one or more regions 19 of appreciably reduced area of cross-section and relatively short axial length each lying directly between regions of the straight part which are of relatively long axial length and have the full area of cross-section of the tube in order to prevent sodium migration The envelope 1 contains a filling of neon with 0À5 per cent. volume of argon at a total pressure of 10 mms., together with sodium vapour, and about 1 gram of sodium. The sodium vapour pressure in normal operation is much less than 1 mm., usually about 0À01 mm. The inner surface of the envelope has a coating of sodium resistant glass. The minimum area of crosssection of each region of reduced cross-section is approximately 20 to 25 per cent. less than the full area of cross-section of the envelope. The reduction in the area of cross-section can be effected by heating a glass tube from which the envelope is formed on one side to soften the glass and allowing the softened glass to collapse inwards for a predetermined distance, or by heating an annular zone of the glass tube to soften the tube and drawing the ends of the tube slightly away from each other to form an annular depression. The exhaust pipe 20 can be located in a region of the envelope of reduced area of cross-section. Each lead-in wire 5 of the electrodes 2 is secured to a corresponding mounting wire 6 by a nickel sleeve 9 which fits over and is welded to the bent ends of the wires. As described in Specification 801,482 a glass heat-insulating sleeve 10 is closely spaced around the envelope 1 and axial movement of the sleeve is prevented by mica discs 11 centrally apertured to receive the pinches 12. The discs 11 are held in position by a wire 13 connected to a lead-in wire 5 and passing round notches 21 in the discs to be connected to the same lead-in wire. The wire 13 also acts as a starting aid. Rattling of the sleeve 10 is prevented by spring members formed by corrugated coils 14, movement of the coils being prevented by the wire 13 being looped around part thereof. At each end of the lamp a cored getter wire 15, which is part of a closed conducting loop 16, is mounted on a support wire 17 and can be heated by induced eddy currents to provide a deposit on the inner wall of the evacuated jacket 3 to absorb occluded gases.
