In a steam trap having inlet and discharge passages 11 and 12 between which is disposed a valve device including a stationary seat member 17 and valve member 38 which is movable by differential fluid pressure on opposite sides of the valve member into an open position permitting discharge of condensate through the valve device, and into a closed position preventing the passage of steam, the valve rests on a valve seat 30 which is divergent, communicating at its narrower end with the inlet passage 11, at its wider end with a control chamber 31, and at a position between the ends with the discharge passage 12; when the valve 38 is off the seat 30 a divergent passage is formed which increases in cross-sectional area from the inlet to the control chamber 31, but when the valve is on the seat the inlet passage 11, control chamber 21 and discharge passage 12 are all sealed from each other. A lower closure cap 27 receives any solid or other material collected by a filter 25 and may be unscrewed in order to clean or renew the filter. An upper screwthreaded closure cap 20 is formed with a faceted boss 22 to enable sufficient pressure to be applied to the seat member 17. An annular clearance groove 32 communicates with four condensate discharge ports 33, and another annular groove 35 is also formed in the socket 15 such that an annular passage 36 is defined by these grooves which communicates with the discharge passage 12 by a port 37. A cylindrical guide pin 42 slidably engages a blind opening 43 so as to prevent undue transverse rocking of the valve member 38. A stabilizing passage or passages 45 (Fig. 3, not shown) to control the frequency of operation of the trap, may be provided between the control chamber 31 and the discharge passage 12, or between the inlet passage and the control chamber. These passages remain open when the valve member is on the seat member so as to provide controlled communication between the various passages and chamber.

Title: Improvements in or relating to condenser discharge blasting apparatus for explosive charges or shots
IPC: F42D1/05
Filed: 1958-04-24
Abstract: 886,107. Charging and discharging condenser detonator devices. NITROGLYCERIN A.B. April 24, 1958 [Nov. 4, 1957], No. 12989/58. Addition to 792,039. Class 38 (4). An electric detonator device for explosive charges is designed to ensure that a sufficient electric charge is always passed to the explosive charges. A potential source, such as a handdriven generator 2 having a voltage-doubling rectifier unit 4, charges a metallized paper capacitor 1 via contacts on switches 7 and 9. A discharge resistor 8 is connected across the capacitor via contacts on the switches 7 and 9. In use the switch 9 is depressed so as to connect the potential source to the capacitor and the capacitor is then charged. Depression of the switch 9 also disconnects the resistor 8. Without releasing switch 9, the switch 7 is then depressed which connects the terminals 6 of the detonator circuit to the capacitor. The depression of the switch 7 also breaks the discharge circuit through the resistor 8 to ensure that the charge may not be accidentally lost and it also disconnects the charging circuit so that the terminals 6 may not be connected directly to the potential source.
Patent GB-634934-A (GB)
Title: Manufacture of insecticidal preparations
IPC: A01N25/04
Filed: 1947-05-14
Abstract: Aqueous insecticidal dispersions are prepared by dispersing a molten isomeric mixture of dichloro-diphenyl-trichlorethane (preferably containing 72-85 per cent of the p-isomer) in a heated aqueous medium containing a ligno-sulphonic acid or salt thereof to form a dispersion of globular liquid particles, cooling the dispersion to ordinary temperature sufficiently rapidly to maintain the globular liquid form of the particles, re-heating the cooled dispersion to a temperature below the incipient melting point of the isomeric mixture to convert the liquid particles into crystals and agitating the dispersion during at least the earlier part of the re-heating operation.  A surface-active substance such as a fatty acid soap or a salt of sulphonated lauryl alcohol with ammonia, triethanolamine or cyclohexylamine may be mixed with the dipersion prior to the re-heating operation.  The cooled dispersion is preferably maintained at ordinary temperature for 7-14 days and the mixture is then stirred for a short time prior to the re-heating operation which may be effected at 50-70 DEG C, say 60 DEG C for about 2 hours.  A protective colloid such as starch, dextrin or gum arabic may be added at any stage.  In preparing the initial emulsion, the molten material may be added in small portions at intervals to the hot aqueous medium, or alternatively, the solid mixture may be added to the aqueous medium heated to above its melting point.  Preferably a high speed emulsifying machine is used in preparing the emulsions. Specification 547,871 is referred to.

Title: Shock absorbers
IPC: F16F9/48
Filed: 1973-03-19
Abstract: 1455847 Crash barriers ROAD RESEARCH Ltd 8 March 1974 [19 March 1973] 13086/73 Heading E1G [Also in Division F2] An hydraulic pneumatic or fluent solid piston-cylinder shock absorber for a highway crash barrier, of the type having a liner 8 in the cylinder 1 with a slot 9a in it to provide a flow path from one side of the piston 2 to the other, is provided with a further liner 9 which deforms under the pressure of the fluid to vary the size of the flow path. The damping is therefore dependent on local pressure as well as piston position. The first liner 8 is made of relatively rigid material e.g. steel, aluminium, or PTFE. The further liner 9 is a tube of yieldable material, e.g. solid or foamed rubber, PVC. polyethylene, or polyurethane surrounding the first liner. The liner 9 is formed with recesses 17 or apertures to facilitate its deformation under pressure.  On impact, "fluid" (gas, oil, siliconised rubber or synthetic plastics material) flows from the chamber in front of the piston 4 through the slot 9a to the rear of the piston and then via apertures 27 into the hollow piston rod to move a spring-biased floating piston 25. When the pressure builds up, the liner 9 expands to increase the size of the flow path. At high pressures, the damping characteristic is dependent on the expansion of the liner 9 rather than the shape of the slot in the liner 8. An alternative slot shape is described.
