Title: Improvements in slag conditioning means
Inventor: HARDGROVE RALPH MARTIN
IPC: F23J1/00
Filed: 1961-06-09
Abstract: Molten slag from a furnace, particularly that produced by the combustion of solid fuel, is cooled to a solid from by discharging the slag so as to form a layer and maintaining the layer in a cooling liquid the surface of which is below the upper surface of the molten layer until this layer has solidified.  Fig. 1 shows a suitable apparatus. The molten material leaving the furnace flows through secondary combustion chamber 11, is discharged through slag outlet 10 in a uniform stream and is directed through enclosure 12 into tank 13.  This tank is full of water, the level of which is maintained substantially constant by means of a valved water inlet connection 18 and an adjustable overflow gate 20, and it also contains a pan-type conveyer 21 disposed as shown with the molten ash receiving surface 22 of the upper run of the conveyer situated immediately, e.g. approximately half an inch, below the water level 23. The slag falls on to 21 and is then transported horizontally through the water into an extension 32 of the tank 13 where the conveyer rises gradually so that the now solidified slag comes out of the water and is discharged into container 35.  At this point, the slabs of solidified slag are broken by pneumatic or hydraulic hammer 37 into smaller pieces that are discharged by conveyer 36 through a sealing-feeding device 65 for delivery to an associated crusher (not shown).  In another embodiment (Fig. 3, not shown) the slag as it comes off the first conveyer is discharged through a shoot into a rotary breaker which further reduces the size of the slag pieces and is also perforated to allow pieces of selected size to fall on to a shaking grate.  On here the slag is submitted to further cooling by passing air from an inlet through the grate and thence through the rotary breaker by which means the air used is preheated, and after cleaning via dust separators is discharged through a duct for use in the combustion process.  The slag pieces from the surface of the grate and the fines which fall through to a conveyer situated beneath the grate are discharged on to a further conveyer for disposal.  If the amount of slag issuing from the furnace is too great for the primary conveying system, it overflows and is granulated in the initial tank from which it can be removed.  Specification 552,747 is referred to. <PICT:0985817/C1/1>

Title: Apparatus for reading a document
Filed: 1960-06-15
Abstract: 879,414. Electric selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 15, 1960 [June 29, 1959], No. 20969/60. Class 40 (1). [Also in Group XIX] In a record-sensing apparatus the sensing means are automatically moved sideways so that they are correctly positioned with respect to the record. The sensing means consist of a mask which is connected on one side by rod 10 to a lever 12 urged toward the left by spring 15. The lower end of lever 12 is connected to lever 17. The upper end of lever 12 and both ends of lever 17 are connected to latches 22, 19 and 18 coacting with abutments 25. A cam 30 rotating once in each card cycle moves the mask to the right to load the spring 15 and allow latches 22, 19 and 18 to latch. Solenoids 23, 21 and 20, when energized, release their associated latches and allow the mask to move towards the left under the action of spring 15. The proportions of levers 12 and 17 are such that solenoid 20 allows one unit of movement, solenoid 21 two, and solenoid 22 four units of movement. By suitable selection of solenoids alignment movements of any number of seven steps can be effected. Solenoid selection.-The record has a pair of sloping lines 33, 34, Fig. 3, to be sensed by two spots of light 39a, 39b. The interval of time t1 t2 between the sensing of line 33 and line 34 depends upon the lateral position of the line with respect to the spots 39a, 39b. Light reflected from the spots is received by phototransistors 36, 37. The signal from the former is used to set a latch circuit and start a multivibrator which produces up to seven pulses in the time corresponding to the maximum misalignment of the record. The latch is reset by the signal from photo-transistor 37. Pulses from the multivibrator pass to a 3-stage binary counter the output of which is switched to the solenoids by a cam-contact to effect the positioning of the mask before the record arrives at the sensing station. Instead of using two sloping lines, a series of lines 105, Fig. 4, may be used, the ends lying on a sloping line so that spot 39a senses a number depending on their position relative to the spot. Each line causes a pulse to pass to the counter to make the correction as before. Both sides of the record may be sensed there being a similarly movable mask also below the record.
