Title: Apparatus for investigating aerosol particle size distribution
IPC: G01N15/06
Filed: 1965-07-26
Abstract: 1,112,254. Irradiation apparatus. GENERAL ELECTRIC CO. 26 July, 1965 [4 Aug., 1964], No. 31757/65. Heading H5R. [Also in Division B2] In the determination of the size distribution in a gaseous sample of aerosol particles in order to compare this with a model aerosol, before passing the gas into a condensation nuclei meter to count the aerosol particle concentration, the gas is passed through diffusion box 22 which acts also as a denuder when a potential difference is set up between two sets of collecting members 25a, 25b. A source of radiant energy 34 is mounted in the input plenum of the box to bring the aerosols in the gas sample to electrical equilibrium. The diffuser-denuder box comprises the gastight housing 22 with an input conduit 31 feeding to input plenum chamber 23, provided with an alpha-particle source 34 for irradiation of the gas which emerges from conduit 31 in a swirling vortex. The collecting members comprise two sets of flat parallel plates 25a, 25b, the plates of each set being connected electrically to respective ones of a pair of terminals (27, 28) to which can be connected to 100 volt source, when required. Alternatively, the collecting members could be concentrically arranged cylinders. The diffuser-denuder operates as follows. When the power to terminals 27, 28 is not supplied, only smaller aerosol particles diffuse towards the collecting members and are removed from the gas stream by collection. With the collecting members energized, e.g. one set at 100v, one at earth, besides diffusion of the smaller particles, larger particles drift towards the terminals and the stream is thereby denuded of these. The action of the radiation source 34 is necessary since any variation from charge equilibrium will adversely influence measurements. In the determinaton of the aerosol particle size distribution (Fig. 1, not shown), a condensation nuclei meter 15 is used to measure the number of particles, in the aerosol particle size range, in a unit volume of gas passing through it. Firstly, the gas stream is measured without passing it through the diffuser-denuder 11, to obtain the total number of particles. Then the loss due to diffusion alone, and then diffusion plus denuding, is determined by passing the stream through the apparatus 11 with respectively, the collector plates unenergized and then energized. The loss due to denuding only, can then be calculated. By comparison with curves for diffusion and denuding (Fig. 5, not shown), the deviation from a model aerosol can be determined.

Title: Improvements in or relating to automatic feed control of arc-light carbons
IPC: H05B31/00
Filed: 1945-11-27
Abstract: 611,734. Automatic control systems for arc lamps. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Nov. 27, 1945, No. 32012. [Class 38 (iv)] [Also in Group XXXVII] In an automatic feed control system for are light carbons, an optical system comprising a mirror mounted at an angle adjacent to one end of a tube carrying a lens focuses a real image of the positive crater on to the sensitive element of a thermostatic switch, mounted at the opposite end of the tube, controlling the speed of a motor feeding the positive carbon. In Fig. 1 a mirror 2 mounted at one end of a tube 1 transmits heat radiated from the positive crater of a carbon arc (not shown) to a thermostat 4 mounted on a telescopic member 3 at the other end of the tube. Member 3 is adjusted along the axis of tube 1 so that a real image of the positive crater is focused on to the thermostat by a lens 5. Tube 1 is adjustably mounted on the framework carrying the arc mechanism (not shown) and screens such as 26 minimize the effect of stray radiation. The thermostat, Fig. 8, comprises two bimetallic strips 9 and 10 connected at their lower ends by bar 11. The upper end of strip 9 carries a contact co-operating with a fixed contact, the position of which is adjustable by a screw 18 to set the differential of control, determined by the position of the contacts relative to permanent magnet 19. The upper end of strip 10, which acts as a compensating strip for ambient temperature changes and increases sensitivity, is fixed to a bracket 12, the position of the upper end of which is adjustable by a screw 20 to set the datum of control by arranging that the thermostat contacts are just closed when the crater image is central relative to strips 9 and 10, as shown on a ground glass screen. This corresponds to thermostat 4 closed, Fig. 9, energizing a relay 21 to connect the armature 22, of a motor feeding the positive carbon, to a low-voltage tapping on a supply potentiometer 23. The feed is then too slow and the image moves toward strip 10 to open the thermostat contacts and change over relay 21 to connect armature 22 to a high-voltage tapping on potentiometer 23, whereupon the feed is too fast. The feed motor thus hunts between two speeds to maintain the image central. In an alternative form of thermostat, Fig. 11, the adjustment of the end of the temperature compensating strip is by rotation of a cam 28 with a screw 32 as trimmer.

Abstract: 183,794. Polet, L. July 26, 1921, [Convention date]. Shuttles, changing bobbins in, automatically.- In looms having horizontal changing of bobbins, when the weft breaks &c., a slide 4, Fig. 1, carrying the weft fork 3 is operated and a finger 7 is withdrawn from underneath a boss on a lever 9 on a shaft 10, Figs. 1 and 3. This shaft then rocks and a lever 12 thereon ceases to support a finger 13 of a rocker 14 pivoted on a rod or slide 15 connected to an horizontal lever 18. The rocker then moves into position to be engaged by a lay tappet 16 and the lever 18 is rocked against the action of a spring-controlled chain 22, thereby operating a part 19 adjustably mounted on an extension of a charger 20, which is moved horizontally in guide-members 24 to transfer a bobbin from the magazine into the shuttle. The bobbins in the magazine are supported by a spring-controlled hinged plate 26 and horizontal springs project from the bottoms of the uprights or slideways 27, 28 of the magazine. If the shuttle is not correctly positioned, it acts on and rocks a spring- controlled safety finger 30, which raises the rocker 14 and prevents operation of the charger. The weft-ends pass between pinions 32, and through an eye of a lever 39 and a hook on a rod 29. Each time the shaft 10 rocks, a pawl on a lever 37 turns one of the pinions 32 and a lever 40 tips the lever 39, which is pivoted to a part 2, whereby the " hanging " weft-end is first slackened and then tensioned.

An insulating casing 1 is closed by a flexible diaphragm 3 carrying a plate 46 with a flat strip 47, bent up therefrom or riveted thereto, which operates a snap-action switch under pressure of gas or liquid admitted via pipe 7. The switch comprises a leaf-spring divided into two tension elements 41, and compression elements 42, 43, the element 43 being a rigid strip forked at both ends. The spring is anchored to a terminal 11 at one end and carries contacts 9, 10 at the other end, for co-operation with fixed contacts 19, 20 secured respectively to terminals 21, 23. The position of contact 20 is adjustable by means of a screw 24. The end of strip 47 is cut away as shown in Fig. 3 to engage a slot in plate 43 with lost-motion, and its extreme end is guided by a blade spring 50 depending from terminal 11, and acted on by a coil spring 25 which is adjustable by a screw 29 engaging the follower sleeve 27. The switch differential may be varied independently of the contact gap by substituting a push-rod 47 with different lost-motion, thus enabling the gap to be kept small. The lost-motion also allows increased contact pressure and separating force, and allows the snap spring to operate substantially without reactionary movement of the diaphragm.
