Title: Improvements in soot blowers and the like
Inventor: MASHEDER HENRY
IPC: F28G3/16
Filed: 1949-05-24
Abstract: 670,040. Sootblowers. IVOR POWER SPECIALTY CO., Ltd. Oct. 10, 1949 [May 24, 1949], No. 13818/49. Class 99 (ii) In a sootblower in which the blower tube 5, Fig. 11, is continuously rotated by a shaft 14 to which it is keyed at 20, and is initially projected to the blowing position by a pin 11 on the housing 1 engaging a helical groove 10 in the rotating blower tube, ports 9 in the blower tube register with the steam inlet 6 when the tube is in the blowing position, and are shut off from the front end of the tube in the retracted position by a piston-like valve member 22 carried by the shaft 14. The helical groove merges into an annular groove 21 whereby the blower tube rotates without translation in the operative position. The shaft is journalled in a bearing- block 16, sealed by packing 15, and operated by a hand-wheel 13. The valve member 22 has a passage 24<SP>1</SP>, Fig. 2, controlled by a spring-loaded ball valve 231 for the escape of fluid trapped between the valve member and the bearing-block 16. The pin 11 carries an anti-friction roller 12, Fig. 2, which engages the groove 10 and is supplied with lubricant by a lubricator 26. In a modified sootblower, also of the retractable type, the blower tube 5 is reciprocated by a feedscrew 35, Fig. 4, engaging a nut 36 secured on the end of the blower tube which is prevented from rotation by a pin 42 on the housing engaging a longitudinal groove 41 in the tube until the latter reaches the blowing position where the pin entering a peripheral groove 44 allows the tube to rotate. The piston-like valve member 37 is pressed by a spring 38 against a shoulder 39 in the blower tube, thereby covering ports 40 in the tube, and advances with the tube until it engages an abutment 43 on the end of the feed screw uncovering as the tube advances the ports 40 when they are coincident with the inlet 6. In a further modification applied to a sootblower of the type in which the blower tube 5 is mounted for rotation only the valve member 22, Fig. 3, is movable in the blower tube by screw-threaded engagement with a screwed spindle 26, a pin 27 on the valve engaging a longitudinal groove 28 in the blower tube. The valve seats on a shoulder 25 to close ports 24 in the blower tube which are in constant communication with the inlet 6. When the valve is withdrawn to open the ports, the blower tube is clutched to the spindle 26 by a bevelled shoulder 31 engaging a recess 30 in the end of the valve. The clutch is freed by a stop in a peripheral groove 33 of the blower tube engaging a pin 34 in the housing.

Patent GB-401720-A (GB)
Title: Improvements in or relating to the flotation concentration of ores
IPC: B03D1/06
Filed: 1932-05-18
Abstract: In the flotation concentration of ores, particularly ores in which the values are intergrown with the gangue, the ore is coarsely ground and concentrated by flotation to give a concentrate rich in values, the unfloated part of the ore is then subjected to a second flotation operation to give a second concentrate, and this concentrate, after the whole or the coarser particles thereof have been reground, is again concentrated by flotation to recover the remainder of the values.  The process is described with reference to the concentration of copper sulphide minerals, e.g. chalcopyrite mixed with pyrites, and to the differential separation of galena and blende.  In concentrating chalcopyrite the ore after coarse grinding is floated in an alkaline pulp containing thiocarbanilide, sodium cyanide, and pine oil.  After removal of the concentrate, pine oil and xanthate are added to give the second concentrate which is reground in an alkaline pulp, conditioned with sodium cyanide with or without xanthate, and reconcentrated.  In the differential separation of galena and blende the ore is coarsely ground in water containing sodium cyanide and lime or soda ash and is then concentrated with cresol and xanthate.  After removal of the concentrate, a further concentrate is obtained by re-agitating with more cresol and xanthate with or without copper sulphate.  The coarse particles of this concentrate are reground with sodium cyanide, zinc sulphate, and lime or soda ash and the whole concentrate is then reconcentrated with cresol and xanthate.  The froth obtained may be re-cleaned by treatment in the presence of sodium cyanide, soda ash, and zinc sulphate.

Title: Improvements in hydraulic systems for loading rollers
IPC: D21G1/00
Filed: 1937-05-21
Abstract: 487,093. Hydraulic systems for loading machine rollers. HAUBOLD AKT.- GES., C. G. May 21, 1937, No. 14177. Convention date, June 9, 1936. [Class 69 (ii)] In a hydraulic system for loading rollers in roller - apparatus, for example, calendering apparatus, dealing with paper, card, fabric or the like, a relief-valve provided in the loading line for limiting the maximum loading pressure and a control-device responsive to the pressure in said line and adapted for reducing the quantity delivered by the pump-means when the said pressure reaches a predetermined value are adjustable together by a common adjusting means for varying the pressures at which they operate. As applied to a multiple-roller apparatus as, e.g. a five-roller calendering machine, the rollers 1 ... 5 are loaded and relieved by pistons 8, 9 working in cylinders 14, 15 and operating through piston-rods 10, 11. The distributing valves 25 are connected by a rod 250 and in the loading position of the valves, oil from the pumps 16, 17 is delivered to the loading lines 26, the exhaust from the cylinders passing to lines 27 which are connected to the return lines 28, 19. The quantity delivered by each pump is controlled by a lever 21 working between stops 22, 23 and connected to a piston 32 working in a cylinder 33 containing a second piston 35 which through a hand screw-adjusting member 36 carries a relief-valve 37 ; a spring 40 arranged between the pistons 32, 35 holds the relief valve 37 against its seat and the lever 21 against stop 22, i.e. in the maximum delivery position. When the rollers have come into contact, the rising pressure in line 26 acts through line 34 to move the piston 32 upwardly and thus reduce the pump output to a minimum ; further rise of pressure acts through line 380 and opens the relief-valve 37. Pressure gauges indicate the pressure in lines 26. In the relieving position of the valves 25, the lines 26 are connected to the return pipes 28, 19, the relief-valve 37 closing and the pump control 21 returning to maximum output setting. Oil from the pumps passes to the relieving lines 27 ; a relief-valve 41 is provided for the relieving lines ; alternatively, an automatic controldevice and relief-valve, such as described in connection with the lines 26, may be provided also in connection with each of the lines 27. As shown, an automatic control-device and relief-valve is provided for each side of the calendering machine to permit independent adjustment of the pressure on either side; each pump is driven by its own motor, or the pumps may be driven by a common transmission. Alternatively, the two sides may be regulated to have the same pressure by the use of a single control-device and relief-valve common to the two sides.

Title: Improvements in or relating to methods of making sound records and to sound-recording and sound-reproducing apparatus
IPC: G11B3/00
Filed: 1946-05-14
Abstract: 612,163. Recording and reproducing sound. LIVY, W. H. May 14, 1946, No. 14491. [Class 40 (iv)] In a method of recording sound in which a plurality of signals of overlapping frequency ranges are recorded in a single track or groove, a sideband resulting from modulating a carrier with a first signal is mixed with a second signal and a pilot frequency which may be the carrier frequency or a harmonic or subharmonic thereof. As applied to a system of binaural recording in which the frequency range of the signals is 0-6 kc./s.,-one signal, programme 1, Fig. 1, is passed directly through an amplifier 2 to a mixer 3. The second signal, programme 2, passes through an amplifier 4 to a modulator 5, where it is mixed with a 13 kc./s. carrier from an oscillator 6, and thence through a 7-13 kc./s. filter 7, which selects the lower sideband, to the mixer 3. The mixer 3 also receives the carrier frequency directly from the oscillator 6. In the reproducing equipment, Fig. 2, a filter 12 separates the three channels, the first signal of 0-6 kc./s. then being passed directly through an amplifier 13 to a reproducer 14 while the sideband signal of 7-13 kc./s. is passed to a modulator 15. The 13 kc./s. pilot frequency is used to lock a local 13 kc./s. oscillator 16 whose output is mixed with the sideband in modulator 15 and the resultant frequency band of 0-6 kc./s. is selected in filter 17 and passed to the second reproducer. The locking of the local oscillator 16 by the recorded carrier frequency ensures that there shall be no discrepancy in frequency between the two speech signals if speed variations occur in either the recording or reproducing turntables.
