IPC: C23C8/26
Filed: 1930-11-20
Abstract: Steel alloys containing 9-17 per cent of manganese, 2,5-10 per cent of nickel, and up to 1 per cent of carbon, and if desired from 0,1 to 10 per cent of one or more additional elements such as silicon, chromium, tungsten, aluminium, copper, molybdenum, cobalt, vanadium, titanium, or zirconium are nitrogenized by heating at a temperature from 500 or 550 DEG  C and upwards to 650-680 DEG  C. in the presence of ammonia or a substance from which ammonia is evolved when heated. The heating may be carried at one or different temperatures.  Before the nitrogenization, the alloys are toughened by heating to 900-1000 DEG  C. and quenched.  In an example, an alloy containing 0,71 per cent of carbon, 1,27 of silicon, 12,8 of manganese, 0,15 of chromium, 2,83 of nickel, and 0,18 of copper was first heated to 1000 DEG  C. and cooled in air.  The alloy was then heated for 48 hours in ammonia at 530-595 DEG  C. of which 40 hours were at 560-585 DEG  C.

Title: Improvements in or relating to refrigerating systems
IPC: F25D21/00
Filed: 1935-12-19
Abstract: 472,615. Thermallyactuated valves. ELECTROLUX, Ltd. Dec. 19, 1935, No. 35209. Void. Convention date, Dec. 19, 1934. [Class 135] [Also in Group XIII] Defrosting of a thermostatically controlled evaporator 15, Fig. 2, of a cabinet, particularly one having a gas-heated generator 16, is effected by manual actuation of a knob 57, preferably located on the face of the evaporator as shown, to displace the thermal control element abnormally to shut off the supply of fuel and thereby allow the evaporator to become warm, the thermal control device 21 being constructed so that it resumes normal control automatically after the defrosting. The control device comprises an expansible diaphragm 36, Fig. 3, connected through a passage 45 in a stud 37 and a flexible capillary tube 46 with a sensitive bulb 47 on or near the evaporator. The stud is clamped to a flexible daphragm 34 secured between parts of the casing and carries a yoke member 38 within which is mounted a system of levers for transmitting movement of the expansible diaphragm to a triangular stem 32 of a fuel valve 31 urged to the closed position shown by a spring 33. The lever system comprises two arms 39, 40 mounted on a common pivot 41 on the yoke member and urged apart by a spring 43, which at its upper end engages a pivoted catch 42 serving to retain the ends of the arms together. The diaphragm stud 37 is provided with a cam 63 of not more than a semicircle, engaged by a lug 54 on a pin 50, which is clamped in a screwed sleeve 49 forming the means for varying the range of the thermal control, the sleeve preferably being rotatable by flexible belt transmission 62, Fig. 2, from the shaft 59 of the knob 57. Another lug 64 on the pin 50 is adapted to ride on the stud cam only when the pin is given more than half a turn from the setting knob 57, for defrosting. This action causes the arm 40 to be pressed inwards by the valve stem and its upper end to be moved into an inner notch 65 of the catch 42. The setting knob is now turned back to one of the normal control positions, and by reason of the retracted position of the arm 40 the expansible diaphragm does not open the valve until after a defrosting temperature has been attained. In this period an arm 66 of the catch 42 engages a stop 67 on the yoke and the catch is tripped to allow the arm 40 to move outwards to its normal catch position.

Title: Control mechanism for rock cutting equipment
IPC: E21C35/24
Filed: 1972-07-27
Abstract: 1394168 Rock cutting equipment ANGLOTRANSVAAL CONSOLIDATED INVESTMENT CO LTD 27 July 1972 [29 July 1971] 35241/72 Heading E1F [Also in Division G3] A rock cutting machine comprises a rotor revolvable about an axis 22 on a traversable support (not shown), swinging hammers 1, 2 mounted on the rotor at pivot points 31, means for generating a signal when at least one hammer has swung back to a predetermined position after an operational impact, and a unit using this signal to provide an indication of the nature of the impact, the indication allowing the rate of traverse of the rotor support to be adjusted for optimum stacking of the hammers. As shown in Fig 1 the support moves the rotor in direction 21, the rotor turns in direction 3, and after each impact the hammers swing back to hit a shock absorber 7 to force a jet of water out at point 8. This swinging back can be signalled in one of three ways: by a reed switch 9 actuated by a magnet 10, by a switch 11 depressed by part 12 of the shock absorber 7, or by a pressure switch mounted at 11 and connected to the water jet passage. Fig 3 shows one form of indicating unit: a segment 14 of a commutator on the rotor moves, in the region of each impact position, past a series of brushes 15 a-g associated with a set of dimly lit lamps 20a-g and when a signal is generated by a hammer, i.e. via switch 9, a circuit is made with whichever of the brushes 15 is being contacted by the commutator segment 14 and the associated lamps of the set burn more brightly. The brighter burning of a particular group of lamps in the set 20 can be associated with the optimum striking of the hammer and the rate of traverse of the rotor support can be adjusted by an operator watching the lamps until the correct group, which may be a different colour to the others, lights brightly. The traverse rate can be adjusted automatically. In a modification of this unit (Fig 4, not shown), the commutator/brush arrangement 14, 15 is replaced by magnets (24) on the rotor or drive chain sprocket of the rotor which move past a non- rotatably mounted group of reed switches (26) associated with the set of lamps. Another embodiment (Fig 5 not shown) employs the jet of water issuing at point 8 as the signal and the indicating unit comprises a set of pressure sensitive detectors (32) at which the jet is directed as the rotor revolves in the region of the impact point.

IPC: B65B1/46
Filed: 1967-08-01
Abstract: 1,174,453. Packaging-machines; conveyers. PNEUMATIC SCALE CORP. 1 Aug., 1967, No. 35320/67. Headings B8A and B8C. A container filling machine of the kind in which weighing units move continuously with containers and deposit material in them prior to their being directed to a discharge path, includes a device enabling an operator to divert a container filled by a particular unit, to another path so that it may be examined for accuracy of weight. Means may be provided to divert a whole series equal to the number of units and the device may be used to prevent containers filled by a unit in which a fault is detected, reaching the discharge path. The condition is indicated by a visual signal to distinguish it from test diversion, should both occur together. The filling apparatus is of the kind described in U.S. Specification 2,868,375. Filled containers leaving this machine are normally engaged by a rotary discharge disc 70 and transferred to a discharge conveyer 60. Associated with each pocket of the disc is a clamping arm 108, normally retained ineffective by a latch on a bell crank 124 mounted on the underside of the disc adjacent each arm. On the operator pressing a switch button corresponding to one or more units, connections in a circuit, Fig. 10 (not shown), are established so that a solenoid projects a cam element 120 into the path of the bell-crank associated with the pocket which has received a container from the selected unit. The latch releases the particular arm which is then under the control of a cam 140. A dip in the latter causes the respective container to be gripped by the arm while passing across the conveyer 60 and the following rise releases it on to a conveyer 104.

Abstract: 840,159. Gas analysers. MINE SAFETY APPLIANCES CO. Nov. 10, 1958, No. 36012/58. Class 40 (1). A combustible gas-testing apparatus comprises a detector filament, treated to give it catalytic oxidizing properties of the gas to be tested, arranged together with a compensating filament to form the two arms in one branch of a Wheatstone bridge circuit, the power supply to the bridge being adjusted by a servo mechanism to keep the detector filament temperature constant. The compensator filament is substantially identical to the detector filament except that it is not treated to cause oxidation of the combustible gas and may be treated to prevent it. Fig. 2 shows a preferred embodiment of the invention in which detector filament 1, compensator filament 2, and resistors 3, 4 and 5, form a Wheatstone bridge, 5 being a potentiometer for adjusting the initial valance of the bridge in the absence of any combustible gas. Resistors 22, 23, 24 and 25 and detector filament 1 form a second bridge fed with A.C. from source 32 and the output of this bridge is used via servo system 35 and motor 36 to control the power supply to the first bridge in order to keep detector filament 1 at a constant temperature irrespective of the amount of combustible gas present. Variations in the power supply, however, vary the temperature, and hence resistance of compensator filament 2, the resulting out-of-balance of the bridge being indicated on meter 7 which may be calibrated in amount of combustible constituent present.
