IPC: F26B17/20
Filed: 1950-03-07
Abstract: 694,723. Drying apparatus. TILTMAN LANGLEY LABORATORIES, Ltd. March 7, 1951 [March 7, 1950; Jan. 11, 1951], Nos. 5778/50 and 833/51. Class 34 (ii) Apparatus for drying crops &c. has a stationary outer drum 7 within which is a rotary inner drum 11 having tines 17, 18 projecting outwardly therefrom to carry the material round the annular space between the drums which space is of small radial depth compared with the diameter of drum 11 and hot gases are circulated through the inner drum and then through the annular space, part of the gases escaping and the remainder being re-circulated. The tines are hingedly mounted and are kept erect by springs 24 which yield if undue resistance is encountered and to turn the material over once per revolution the tines are turned back by engagement with pegs 27. The drum is rotated intermittently by a ratchet 56 engaged by a pawl 57 on an arm 58 pivoted to a crank driven through gearing. The apparatus is mounted on a wheeled chassis 1 and has a burner chamber 29 containing an oil fuel burner with inner cylinder 30 and outer cylinder 31. Primary air enters through perforated plate 34 and secondary air enters the annular space between cylinders 30, 31 to mix with combustion products and emerge into duct 37 leading to a fan 41 and chamber 42 from which the air is blown into the inner drum 11. Material to be dried is loaded through doors 8 and discharged through doors 9. For drying granular material in sacks or bins a ducting 71 (Fig. 8) may be attached to an outlet 69, normally closed by a plate 70 and a shutter 42a closes the entry of chamber 42 so that warm air is discharged into ducting 71, manifold 72 and pipes 73, having branches 74 to which are attached rubber tubes 75 leading to conical perforated nozzles 76 which are pushed into the granular material. Specifications 595,864 and 651,284 are referred to.

The duct 3 may be an expandible, bellowstype tube, an interchangeable fixed length tube, a telescopic tube or, preferably, a series of flanged transparent polymethylmethacrylate tubes built up to the required length. The duct 3 and the device 35 in a base 5 are adjustably mounted on a column 2. A cut-off tray 6 and a support 9 for the sample holder are swivellably mounted on the column 2. A drip tray 10 is provided. A pump 12 feeds water from a reservoir tank 11 to the drop generator 4 and drainage lines 15, 16, 17 lead from the generator 4, the base 5 and the tray 6, respectively, to the tank 11. The generator 4 comprises a showerhead formed in a base 22 provided with barrels 24, e.g. foreshortened hypodermic syringe barrels, leading to needle jets 25 and arranged in two rings. An overflow line 28 provides a constant head. To clean the needles 25 in case of blockage, a connection 29 to a source of pressure pulsation, e.g. a squeeze bulb, is provided. The device 36, Fig. 4, comprises an interchangeable cone of mesh fabric e.g. a heavy quality nylon bolting cloth, and has a base diameter greater than that of the upper end of a cone 33 carried by a member 31 to provide a drainage zone 34.

In operation, a sample 7 is placed over the pad 44 and held taut by weights 8 or clips. This sample is exposed to water droplets falling from the generator 4 through the cone 36 until the water penetrates the sample and gets onto the insulating strip between any two successive conductive strips of the pad 44 and causes a short circuit to operate a detecting circuit to stop the pump 12 and an associated timing clock and to initiate a warning, e.g. a lamp or buzzer, on a panel 13. In a modification, to simulate movement of the fabric during wearing, during testing, one end of the sample is reciprocated by an electric motor while the other end is held by weights.

Title: Improvements relating to the refining of silver alloys
IPC: C25C1/20
Filed: 1947-03-04
Abstract: In a process of extracting silver from a silver alloy containing at least 15 per cent. silver but less than 70 per cent silver, the alloy is dissolved in nitric acid to yield a concentrated solution of metal nitrates and this solution is subjected to electrolysis (see Group XXXVI) to cause silver to be deposited at the cathode.  The spent electrolyte is made slightly acidic with nitric acid and stripped of its silver content by cementation with metallic copper.  This silver is purified by treatment with dilute sulphuric acid followed by washing with water.  Specification 643,668, [Group XXXVI], is referred to.

Title: Improvements in and relating to clothes-wringers
IPC: D06F45/18
Filed: 1942-05-14
Abstract: 562,164. Machinery guards. BRITISH THOMSON-HOUSTON CO., Ltd. May 14, 1942, No. 6540. Convention date, May 17, 1941. [Class 80 (iv)] [Also in Group VIII] In a clothes-wringer in an emergency the roller pressure is released and the power drive thrown off by operating from a handle at either end a shaft which is slid to release the pressure and rotated to throw off the drive, the throw off including a lost motion the first movement of which frees a latch locking the drive in "on" position and the second movement shifts the drive to " off " position. The power shaft 32 has dogs 47 to drive one or other of two loose pinions 31 grooved to engage the arms of a control yoke 40 fixed to a slide 43 operable by a lever 55 pivoted on a shaft 56 and forked to engage a pin 59 fixed in an arm 60 loose on the manual control shaft 50 having handles 49 at either side of the machine. An arm 65 keyed on the shaft 50 has a lost motion drive to a pin 66 on the arm 60, and thus a movement from either extreme position (i.e. direct or reverse drive) first raises a double lever 78 to free the arm 60 and then rocks it and the lever 55 to reverse the drive which is then locked by a notch on arm 60 engaging its tooth 61 on the lever 62. The shaft 50 can be slid longitudinally till a collar 54, or pin 53 thereon, engages a boss on the wringer head, the movement causing the grooved collar 54 on the shaft to rock an arm 71 engaging cam lugs 73 on a lever 74 and thereby thrust against the action of a spring 26 a link 25 and cause the far end thereof to rock a lever 21 to free a latch 20 and upset a toggle held lever end 18 of the cover 13 which flies up, releasing the pressure between the rollers. The cover 13 rising lifts by an attached plate 80, Fig. 1, the lever 62 to free the arm 60, lever 55 and slide 43 which is returned by its spring 44 to mid position to cut off the drive from the lower rolls. In a modification, the latch lever 21 locking the toggle 17, 18 of the end cover, itself carries cams 87 to engage inclined faces on a collar 86 on the sliding shaft 82 so that end movement of the shaft frees the pressure. Rotation of the shaft slides a link 103 on its pin-and-slot biasing 105, 106 and carries along a latch 100, pivoted to a bent lever 97 which raises a slide 91 for reversing or stopping the drive to the lower roll. The latch 100 has notches 108 to engage corresponding teeth 109 on the wringer head and there is lost motion limited by the pins 107 on the link.
