Title: Thermostatic valve
Inventor: HAGENS POUL GUNNAR
IPC: G05D23/19
Filed: 1959-03-02
Abstract: 904,705. Valves. NIELSENS EFTF. A.S., CHR. March 2, 1959, No. 7117/59. Class 135. A valve closure member 10 is actuated by a plunger 7 which is moved in response to changes in temperature of a liquid in a chamber 5 containing an electric heater 14 under the control of a temperature-responsive switch 17 situated in a room in which heating is controlled by the valve. The parts are shown in the positions they occupy when the liquid in the chamber 5 has been heated to cause depression of the plunger 7 which, through a spring 11, has depressed a sleeve 9 and closed the valve. Further heating of the liquid results in further depression of the plunger 7, a rod 12 being free to move in an axial bore in the valve member, until contacts 18 in series with the heater 14 are broken. The liquid is thereby prevented from overheating and straining the valve. When the switch 17 opens the circuit the plunger 7 rises and causes a head 13 on the rod 12 to raise the sleeve 9, thereby allowing a spring 19 to open the valve. Part of the chamber 5 may be constituted by a separate container remote from the valve and connected thereto by a conduit. Also, the chamber 5 or the separate container may be thermallyinsulated.

Title: Improvements in or relating to the production of precipitated copper metal
IPC: B22F9/26
Filed: 1950-03-24
Abstract: Copper is precipitated from solution by reducing cupric ions to the cuprous state by the addition of copper metal and carbon monoxide at temperatures below 100 DEG C, then precipitating the copper by the addition of carbon monoxide at temperatures above 100 DEG C and under increased pressure for sufficient time to precipitate only so much copper as is 99.9 per cent pure but more than that dissolved in the reducing stage, the residual copper-containing liquid being recycled to the solution stage.  In ammoniacal solution the precipitation temperatures may be 110-150 DEG C at pressures of 150-750 lbs. per sq. in. and 20-30 per cent of the available copper may be precipitated.  In acid solution the precipitation temperatures may be 200-250 DEG C at pressures of 300-700 lbs. per sq. in. and 60-75 per cent of the available copper may be precipitated.  The precipitated copper may be further treated with a 1-10 per cent solution of sulphuric acid to prevent oxidation by the atmosphere.

Abstract: 909,867. Fuel injection engines; valve gear. HEINTZ, R. M. March 4, 1959 [March 14, 1958], No. 7463/59. Classes 7(2), 7(3) and 7(6) Fuel is supplied continuously through a nozzle 23<SP>1</SP>, Fig. 1, to a position adjacent an auxiliary air inlet valve 81 opening into the top of a preccmbustion chamber 75 containing a sparking plug 87, whereby when the valve 81 opens, the bulk of the fuel is forced by the entering air towards the bottom of the chamber 75 and an ignitable mixture is formed in the region of the sparking plug 87. The precombustion chamber is formed in a fitting 24 containing the valve 81, fuel nozzle 23<SP>1</SP>, auxiliary air passage 43, and spark plug recess. The auxiliary valve 81 is actuated by a rocker 95 from the rocker 61 of the main inlet valve 61, the fuel collecting around the valve 81 being drawn into the preccmbustion chamber 79 immediately the valve opens so that a rich charge forms in the bottom of the chamber 79 and an ignitable charge forms adjacent spark plug 87. The precombustion chamber outlet orifices 77 may be replaced by a plain slit or a plain Venturi and a re-entrant tube 78 may be provided whereby air forced therethrough on the compression stroke assists stratification of the charge in chamber 79. The fuel is supplied by a pump 9 to a spring-loaded valve 14 controlling the supply to the individual nozzles 23<SP>1</SP> by controlling a by-pass 18 leading to the fuel tank, the loading of the spring 19 being increased, as the throttle valve 41 is opened, to reduce the amount of fuel by-passed. Additional fuel may be injected into the intake pipe 35 at high loads and at idling a throttle valve 41 may be partially closed.

Title: An automatic uncoupling device for rail trucks
IPC: B61G7/04
Filed: 1953-03-19
Abstract: 724,307. Vehicle couplings. RHODE, P. March 19, 1953, No. 7565/53. Class 103 (5). Uncoupling is effected by longitudinal movement of a slide 2 which carries uncoupling segments 3a, 3b on arms pivoted at 14, the segments being caused to rise by means of fixed portions 16, 17. The slide 2 is actuated by the truck wheels moving the two-armed lever 6 which carries pulleys 7, 8 round which operating cables 34, 36 are passed and are attached to the right-hand and left-hand respectively of the slide 2 after passing over pulleys 10, 11. Thus as a truck passes over the uncoupling section, the shackle of the coupling 12 is raised by the fixed incline 15 then the truck wheels move the slide at a speed greater than that of the truck so that the uncoupling segment 3a rides up the incline 16 to engage the hook of the coupling 12 to effect uncoupling. When the truck wheels have passed over the upper part of the lever 6 they meet the upper ends of the levers 4 and rotate them anticlockwise, thus causing the slide to move in a direction opposite to that of the truck. This motion of the slide 2 causes the segment 3b to release the hook of the coupling 13 since the shackle of this coupling has been previously raised by the segment 3b during the forward motion of the slide 2.

[Class 38 (v)] An electromagnetic interrupter which may be used as a potential changer comprises a yoke of permeable material, electromagnetic means associated with said yoke at one end, and a vibratory reed of magnetic material mounted on and magnetically connected to the other end of the yoke with circuit-making and breaking means associated with the reed, wherein the electromagnetic means comprises a single core member having a D.C. exciting winding, said core member being connected at its inner end to one end of said yoke and having its outer end facing the other end of the yoke, the major portion of the body of the vibratory reed being disposed substantially parallel to the axis of the single core member with the free end of the reed extending towards the outer end of said core. As shown in Fig. 1, the armature consists of a vibrating reed 21 of magnetic material secured at its lower end between the arms 12 of an inverted U-shaped yoke and carrying on an off-set part of the upper end a magnetic plate armature 22. The winding 13 is secured on a core 15 secured to the cross limb of the core and a lateral extension 20<1> of the end 20 of one of the limbs of the voke makes contact with the lower end of the reed to complete the magnetic circuit through the reed. The reed bears two pairs of contacts 23, 24, on opposite sides, Fig. 3, adapted to engage contacts on pairs of relatively fixed spring blades 26 and 28, 29 mounted at opposite sides of the reed. The free ends of the fixed contact springs are forked and engage the insulated ends of adjusting stops 36 which are set so that the springs 26, 29 for the two halves of the primary circuit break before and make after the springs 25, 28 for the two halves of the secondary circuit. When the interrupter is switched into circuit the coil 13 is in series with one half of the primary winding so that reed is at once moved and when it closes the primary circuit the operating coil is short circuited. Thus vibration of the reed is maintained and the circuits of the two halves of the primary and secondary circuits are alternately made and broken. The interrupter is mounted within an earthed outer casing 62 lined with sound-insulating material 65, 66 the connections being made by means of plug members 43.. 47. Condensers 56, 59 shunt the primary interrupter contacts for sparking-preventing purposes.
