Title: Hardness-tester
IPC: G01N3/52
Filed: 1962-01-31
Abstract: 960,283. Hardness testers. E. SCHMIDT. Jan. 31, 1962 [Jan. 31, 1961], No. 3619/62. Heading G1S. A hardness tester comprises a generally D-shaped casing 1 provided with legs 2 for correct location against the test-surface 32 (which may be vertical or horizontal), and a swinging hammer 17 which may be released (using button 29) from a fixed starting position (indicated in full lines in Fig. 1) to fall under gravity or, selectively, as described below, to swing under spring loading, the rebound angle being indicated on scale 31 and giving a measure of the hardness. The hammer is held in the extreme rebound position by means of a clamping lever 19 (Fig. 3) which is pivotably mounted in a recess of the hammer and is set to its operative position (in a manner to be described) by the impact, and is so shaped that in the rising movement of the hammer merely produces a braking effect but prevents subsequent falling movement (i.e. in the clockwise direction of Fig. 3). Thus, a lever 22 in the hammer-shank 8 is initially moved to the right (in Figs 3 and 7) to allow the clamping lever to be moved by spring 21 to an inoperative position, and is held by a spring-loaded ball 25. The constraint of the latter is broken by the impact and lever 19 moves to its operative position. As shown in Fig. 4, the hammer-shank is connected by a spring 11 to a sleeve 10 rotatable on the pivot 3. A hand-wheel 16 is rotatable through an arc, limited by pin 13 and slot 16a, and has a pinion 15 engaging rim-gears 12c of three pins 12 rotatably journalled in the bearing 5. Pins 12 have widened semi-circular ends 12d which, according to the setting of wheel 16, can engage recesses in the sleeve 10 to lock the latter with bearing 5. Movement of the hammer to its initial position loads spring 11. As shown in Fig. 9, the tester 40 is movable on a carriage 42 towards an anvil 51. A small test object 48 is held between grooved members 49 and 50, the hammer 44 being provided with a striking pin 43. Alternatively, a "floating" rubberembedded pin may be used.

Title: Improvements in or relating to photocells and method of making the same
IPC: H01J40/00
Filed: 1945-02-14
Abstract: Thallous sulphide employed as the light-sensitive material in a photo-electric cell (see Group XL (b)), is prepared by the direct combination of thallium and sulphur or by precipitation from an alkaline solution of a thallous salt.  Commercial thallium sticks, which usually are heavily oxidized, are purified by heating to about 300 DEG  C. under low-pressure conditions and after physical separation the pure thallium is frozen.  The purified thallium is placed in one side arm of a tube having a second side arm containing a quantity of pure sulphur calculated to allow a slight excess of thallium.  The chamber is evacuated, the thallium melted, the sulphur warmed and the chamber then sealed.  The melted thallium is run into the main tube and the sulphur slowly vaporized.  The resulting compound is heated to about 460 DEG  C., and after cooling to normal temperature, the thallium sulphide, which floats on the small quantity of liquid thallium, solidifies and is separated.  In the second method chemically pure sulphuretted hydrogen is passed through a slightly alkaline solution of thallous nitrate or sulphate in distilled water.  Impurities such as salts of lead, copper or antimony may be removed by passing sulphuretted hydrogen through a slightly acid solution of the thallous salt.  After filtration, the solution is made alkaline and the thallous sulphide precipitated as described above.

Title: Improvements in or relating to a method of charging internal combustion engines with solid, pulverulent fuels
IPC: F02B45/02
Filed: 1936-02-12
Abstract: 470,272. Powdered - fuel engines; valves. PAWLIKOWSKI, R. Feb. 12, 1936, No. 4236. Convention date, Sept. 20, 1935. Addition to 463,283. [Classes 7 (ii) and 7 (vi)] Relates to the method of charging an internal-combustion engine with powdered fuel described in the parent Specification and consists in connecting the charging-cylinder to a control member establishing the alternate connection of the cylinder with the supply vessel and with the intermediate chamber or in arranging the charging-piston in the tubular inlet valve controlling the drawing of the fuel out of the supply vessel. In one form of apparatus, Fig. 1, an air-inlet 17 is arranged horizontally in the bottom of a supply vessel 4 and is controlled by a valve 18, and the fuel outlet is controlled by a valve 13. A turncock 30 is rotatable by means of a lever 31 to connect the vessel 4 alternately with a charging-cylinder 8 and the latter with an intermediate chamber 5. A charging-piston 7 is actuated by a rooking arm 28 the stroke of which may be varied by a screw-stop 26 set by the engine governor to determine the quantity of mixture fed to the engine, In the form shown in Fig. 2, the piston 7 is arranged inside a reciprocating tubular member 10a controlling the supply of the powder-air mixture to the chamber 8, and a valve 11a controls the outlet from the chamber 8. The members 10a, 11a, are actuated by friction from the piston 7. The valve 11a and a valve 11 controlling the outlet from the chamber 5 into the precombustion chamber 3 may both be open during the delivery stroke of the piston 7 so that the chamber 8 functions as an intermediate chamber. In a modification, Fig. 3 (not shown), the cylinder 8 functions as the intermediate chamber, and the air passage therefor is provided in the hollow stem of the valve 11 and is controlled by the movement of the piston 7 relative to the valve 11. The tubular valve 10a and the valve 11 are reciprocated by friction from the piston 7, stops set by hand or by the governor limiting the movements. In Fig. 5, the receptacle 4 is remote from the cylinder 8 and is connected by a pipe 51, and a valve 41 for controlling the supply and strength of the mixture is opened to a variable extent by a lever 45 actuated from the engine governor. Powder is admitted to the valve chamber through an opening 40, and air enters by holes 43 in a hollow valve stem 42. Due to the fact that as the valve 41 descends the powder outlet 40 increases in size and the air outlet decreases, the strength of the mixture increases with increase of load. The powder in the receptacle is stirred by means of a paddle 50 rotated by hand or mechanically, e.g. by a gear segment 48 fixed to an oscillating shaft 53. The valve 11 is replaced by two valves 11, 12 working one within the other. In a further modification, a single charging piston supplies several engine cylinders.

Filed: 1948-02-13
Abstract: 652,048. Pumps. ROLLS-ROYCE, Ltd. Feb. 13, 1948, No. 4324. [Class 7(ii)] [Also in Groups XXVI and XXIX] A power plant comprises a reciprocating internal combustion engine 10, a turbine 15 driven by exhaust gases from the engine, a compressor 20 delivering compressed air into the exhaust gases before their admission to the turbine, and temperature-sensitive means 29 sensitive to the temperature of the mixture of compressed air and exhaust gases which regulates the delivery of compressed air into the exhaust gases, or regulates the supply of exhaust gases, or regulates both the supply of exhaust gases and compressed air so as to maintain a desired temperature of the gases in the turbine. Arrangements, which may be pressure-sensitive, may be made to vary the temperature at which the gases are maintained, so as to vary the power output of the turbine. In Fig. 1, the engine supercharger 12 is driven from the engine crankshaft through gearing in the wheel-case 13, the exhaust gas turbine 15 assisting the drive through bevel gearing and the freewheel clutch 24 which allows the engine crankshaft to over-run the turbine shaft but not vice versa. The air from the auxiliary compressor 20 is delivered by the conduit 19 to a jacket 18 surrounding the exhaust pipe 16 which it enters through the holes shown. The quantity of air mixing with the exhaust gases is controlled by the valve 28 the opening of which is dependent on the temperature-sensitive device 29 operating through the electrical mechanism 30 and reversible motor 31 having a screwed spindle. To control the flow of exhaust gases a valve 33 may be fitted in the exhaust gases to flow direct to atmosphere mally closed but arranged to permit exhaust gases to flow direct to atmosphere only when the valve 28 is fully open. In place of the auxiliary compressor 20, a tapping may be made from the supercharger compressor for supplying air to the exhaust gases.
