Abstract: 1,109,230. Vapour burners. VAPOR CORPORATION. 28 Dec., 1966 [8 April, 1966], No. 57874/66. Heading F4T. A heating system for use on railroad stock comprises a main burner 10 including an annular combustion chamber 13 defined by concentric walls 16 and 17 and an annular bottom wall 18, inner and outer annular combustion air chambers 14 and 15 adjacent said chamber 13 and openings 22, 27a-27f in walls 16 and 17, some of which openings are provided with downwardly extending tubes 22, 28, 29, through which combustion air is delivered to the chamber 13, the system also including a pilot burner 11 arranged below the main burner and comprising a cylindrical combustion chamber 37 with a combustion air chamber 42 surrounding it, air being supplied to chamber 37 through openings 45, 46, 47, the inner wall of chamber 14 defining a flue for the pilot burner. A perforated cylindrical baffle 24 is mounted in the main combustion chamber 13 and combustion products therefrom passing into a chamber 68 contain a coil 12 through which a heating medium passes. A choke 30 and deflector 73 direct the combustion products over the coil before they exhaust through a flue 71. A plenum air chamber 52 surrounds the lower half of the main burner and the pilot burner and is supplied with air through a scoop 62. From chamber 52 air passes to the air chambers 14, 15, 42, pipes 67 arranged in the main combustion chamber supplying the air to the chamber 14. Fuel is supplied to both burners from lines 34 and 41 through inlets 31 and 38 circumferentially and equally spaced around the bases 18 and 36 respectively. In line 41 there is a manually adjustable metering valve 81 and line 34 a float valve 82 and a metering and control valve 83. The valve 82 limits the amount of fuel that can be supplied to combustion chamber 13 and valve 83 meters the fuel to the chamber 13 in response to a capillary and bulb arrangement 84 connected to a control system 85. A needle in valve 83 may be operated by a bellows associated with the arrangement 84. The pilot burner is lit through an access tube (86), Fig. 2 (not shown), and the fuel in the main combustion chamber is ignited through apertures 50, 51 from the pilot combustion chamber. To enhance ignition in the main burner a tungsten wire 88 is mounted just inside apertures 51.

Filed: 1969-11-27
Abstract: 1,261,463. Time switches. OMRON TATEISI ELECTRONICS CO. 27 Nov., 1969 [30 Nov., 1968; 6 Nov., 1969], No. 58026/69. Heading H1N. An interval timer has a driven gear with a toothless portion and electromagnetic means for engaging a drive gear with the driven gear, contacts being operated after a time interval in accordance with rotation of the driven gear, said drive gear running idle in the toothless portion of the driven gear immediately after said time interval. As shown, a motor 20 is coupled through reduction gearing to a gear 24 on a shaft 41, the other end of which carries a pinion 42 for engagement with a gear 40 having a toothless recess 40a. The front end of shaft 41 is journalled in a groove at the back of a support plate 12 to allow a degree of vertical movement such that the shaft 41 may be lifted (against the action of a wire spring arm 43) to disengage pinion 42 from gear 40. The armature plate of an electromagnet 30 is normally lifted by springs 33 to hold pinion 42 disengaged from gear 40, and also to hold contact blades 50a, 53a clear of fixed contacts carried by blades 54 and 55 secured to the rear of support plate 12. The blade 53a is mounted directly to a block 52 carried on the pivoted armature plate, while the blade 50a is carried by a member 51 resiliently pivoted on the block 52 under action of a spring 56. The member 51 has a nose 51c positioned above a cam 44 on the shaft 46a, and a recess 44a in cam 44 is aligned with nose 51c when the toothless recess 40a is aligned with pinion 42. A spiral spring 45 acts on shaft 46a to urge a pointer 46 against a projection 60a inside an annular setting knob 60 so that, with the electromagnet 30 de-energized, rotation of knob 60 sets pointer 46, and hence gear 40 and cam 44, to a position corresponding to the required time interval. Energization of electromagnet 30 by an external switch (not shown) then attracts its armature plate to allow pinion 42 to engage and drive gear 40, and also closes contacts carried on blades 53a, 55. The nose 51c of member 51, however, rides on the periphery of cam 44 until the set time has elapsed, whereupon it drops into recess 44a under action of spring 56 and closes timing contacts carried on blades 50a, 54; the pinion 42 then idles in the toothless recess 40a. De-energization of electromagnet 30 allows springs 33 to lift the contact arms and shaft 41, to free the shaft 46a, and spring 45 returns the pointer 46 to projection 60a in readiness for a further cycle.  The embodiments of Figs. 9 and 10 (not shown) have modified arrangements of electromagnetic clutching and the contacts are replaced by microswitches operated by a pin (120) on the gear (112) with a toothless recess. A conventional knob replaces the annulus 60 in each of these embodiments.

As shown in the Figure the cold trap comprises a stainless steel vessel 1 containing in its upper part a stainless steel cylindrical duct 5 which contains a baffle 10. The lower part contains a cylindrical stainless steel double walled duct 16 connected to duct 5 by flange 15. A stainless steel mesh filter basket 23 containing rings 25 is fitted inside duct 16.
