Filed: 1971-05-18
Abstract: 1333478 Incinerators SHIRCO Inc 18 May 1971 [20 May 1970] 15451/71 Heading F4B An incinerator for refuse, particularly sewage sludge, comprises an elongate combustion chamber 12 heated by units 13 including infrared heating lamps, an endless chain belt conveyer which extends throughout the chamber 12, a refuse feeding conveyer 23, and a stack 130 for combustion products and an ash removal system 14 at the discharge end of the combustion chamber 12. The refuse feeding conveyer 23 also includes infra-red heating units 40 to provide preliminary breakdown of the refuse. The combustion products may be partially recirculated through the combustion chamber via a conduit 170 having a control valve 174 and a valve 175 for inlet of tempering air. A fan 80 delivers air through the heating units 13, the heated air therefrom beng passed to the inlet end of the combustion chamber as combustion supporting air. The heating units 13, and valves 174, 175 may be manually and/or automatically operable in response to temperature sensors 200 and 204. The chain belt is supported by air cooled rollers 91 and staggered scrapers are provided above the belt to agitate the refuse during drying and incineration. The stack 130 communicates with gas scrubbers 150, 154.

Title: Improvements in and connected with the Automatic Valves of Geysers of the Sealed Type.
Inventor: PARKINSON BERNARD ROBERT
IPC: F24H9/20
Filed: 1918-09-25
Abstract: 134,261. Parkinson, B. R. Sept. 25, 1918. Fluid-actuated valves for water heaters. - A liquid-seal valve device for controlling the gas supply to a geyser of the sealed type comprises a V-tube containing mercury, one limb of the tube being connected to the gas-supply pipe, while the other is connected to the outflow pipe of the geyser. Water is supplied to the geyser from an overhead tank 3 through a pipe 2 controlled by a valve 4. The outlet pipe 5 leading to the taps 6 has an overflow connexion 14 discharging into the tank, and is connected to the shorter limb of a V-tube 10. The longer limb is connected to a bend 11 in the gas-supply pipe, which is fitted with a valve-controlled by-pass 9, so that when a tap is opened, the water pressure is reduced, thus allowing the mercury to recede from the bend to permit an increased supply of gas. A second bend 12 fitted with a drain plug acts as a mercury trap. The lower part of the V-tube may be made of reduced diameter.

An electromagnetic hammer comprises a casing, an electromagnet having a coil, a movable armature fast with a striker and a counter structure having two lateral branches fast with the casing and embracing the coil from the outside, the armatures each having a central arm extending axially through the coil, the striker and movable armature being acted upon by resilient means opposing the attraction of the movable armature on energising the coil, the striker and movable armature also being supported for movement by at least two springs the resilient properties of which determine, in the inoperative position, the width of the gap between the central arms of the movable and counter armatures. As shown, the hammer has a casing containing a coil 11, a counter armature comprising an inner arm 14 and two outer branches 13, and a movable armature having an inner arm 15 and two lateral branches 16, the gaps between the armatures in the inoperative position being about one third of the axial length of the coil. The movable armature is held in position by four reaction springs 23 and four synchronising springs 24 each having one end supported by the casing and the other end engaging cups attached to the movable armature, tie rods 27 supporting and guiding the springs and cups. The springs 23 are stiff enough to prevent the armatures from striking each other. The tool spigot 136a is supported in a bush 134 having a linear ball bearing to reduce friction, the tool being maintained in position by a locking device 41. In a modification Fig. 7 (not shown) the linear ball bearing is replaced by two springs acting in opposite directions against the retaining flange of the tool. In a further modification, Fig. 17, the striker 17 is supported by two springs 81, 82 arranged round and coaxial with the striker. In another modification, Fig. 18 (not shown), a separate displaceable central arm of the counter armature bearing on a reaction spring is provided, and the central arms of both armatures are supported in linear ball bearings.

Abstract: 374,265. Steam turbines. THORNYCROFT & CO., Ltd., J. I., Thornycroft House, Smith Square, London, and SHARP, H. E., Woolstan Works, Southampton. June 4, 1931, No. 16314. [Class 110 (iii).] A high pressure steam turbine of impulse reaction and of the divided flow type is provided with valve controlled means to apportion the steam unequally between the two portions of the turbine. Steam is supplied through an in.let 1, Fig. 1, and divided to feed nozzles 4, 5 for sections A, B of the turbine, by means of valves 6, 7. Steam exhausted from section A exhausts either to nozzles 14 of the impulse stage of section B or an intermediate stage through an inlet 12a, or flow directly to a common exhaust pipe 10. Valves 13, 11, 13a are provided in the exhaust pipes. For low powers valve 11 is closed, valve 13 or 13a opened and H.P. steam admitted to section A only. For intermediate powers H.P. steam is also led to section B, and for high powers exhaust valve 11 is opened and valve 13 closed. A valve interlocking gear, Figs. 2 and 3, shows a threaded spindle 15 on the end of which is a hand-wheel. The wheel causes endwise movement of the spindle to open valve 11 and close valves 13 or 13a or vice versa. Spindles 16, 17 are rotated to open or close valves 7. Pawls 20 21, pivoted at 20a, 21a, co-operate with a disc 19 on the spindle 15, and overlap the free ends of spindles 16, 17, to prevent these spindles being moved to the right. Valve spindle 15 must be moved before spindles. 16, 17 can be moved, to shift the disc 19 either to right or left so that the pawls can be pushed aside to block the disc 19 until it is desired to again move spindle 15. In a modification only section A has an impulse section and the exhaust passage 12 is provided with branch passages connected respectively with inlet ends of sections A and B.

June 4, 1931, No. 16322. Convention date, June 5, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (iii).] The apparatus described in Specification 308,695, [Class 40 (iii), Telegraphs, Electric], is modified so that separate adjacent lines of a picture are stated to be simultaneously transmitted and reproduced at a distant station. The picture is mounted on a sheet 2 carried by a semicircular cylindrical member 1 and moved slowly in the direction of the cylinder axis. A fixed light 6 is concentrated on the picture through a window 3 by lenses 5 mounted on a sleeve extension 4 of a hollow shaft rotated by a motor 10. It is stated that light reflected from diametrically opposite unit areas of the picture lying in adjacent scanning lines is collected by lens systems 8, and reflected by prisms 9 to travel along the shaft at the end of which it is separated into two beams by holes 15 in a diaphragm 14. The beams are interrupted at a desired frequency by an independently driven chopperdisc 17, and passed through lenses 20, 21 to photo-electric cells 22, 23 modulating transmitters 24, 25 working on slightly different transmission frequencies. The apparatus at the receiving station is similar to that at the transmitter except that the lenses 5 and the light source 6 are not required. The signals operating two separate receivers are applied to discharge lamps whose light variations are concentrated on a diaphragm corresponding to the member 14, as shown in the Figure. The separated light-beams are reflected to pass through a rotating lens system to trace adjacent paths on a light-sensitive sheet mounted similarly to the sheet 2, as shown in the Figure.
