Title: Automatic dough pan loader
IPC: A21C9/08
Filed: 1950-07-07
Abstract: 686,797. Conveyers. RHODES, H. C. July 7, 1950. [July 7, 1949] No. 17011/50. Class 78 (i). A machine for loading dough into baking pans is of the type having a lower endless belt conveyer for the pans and an upper endless belt conveyer for the dough pieces terminating short of the delivery end of the lower belt, so that dough pieces can fall from the upper belt into the pans on the lower belt, and is characterised by the provision of a dispenser arranged so that the dough pieces first fall from the upper belt into the dispenser, and an air-actuated piston controlled by a preceding dough piece on the upper belt engaging controlling means, for operating the dispenser so as to deposit the piece from the dispenser into the pans. Dough pieces are fed by a belt 15 under a pivoted plate 25 which is lifted by each piece as it passes, and the pieces then fall into a trough-like dispenser which consists of a fixed plate 20 and a pivoted plate 21, Fig. 3. Beneath the dispenser is a belt conveyer 18 which transports sets of dough pans 17, Fig. 4, past the dispenser. As each dough piece passes under plate 25 a supporting shaft 23 is partially rotated and simultaneously actuates two similar valves, one of which is shown at 27, Fig. 3, so as to admit compressed air to corresponding cylinders 42, and a pair of cylinders, each of which is formed in a block 51, Fig. 5. The piston of cylinder 42 operates against a return spring 45 to swing plate 21 through a supporting shaft 22, away from the plate 20, thus releasing a dough piece from the dispenser into one of the pans P below. The sets of pans 17 are temporarily stopped to receive the dough pieces by two fingers 47, 48, Fig. 4, mounted on pivots 50 on the blocks 51. Upon supply of air to the cylinders in block 51, the pistons of these cylinders, each acting against a return spring 56, depress simultaneously both fingers 47, 48, so that as a pan receives a dough piece, it starts to move. As the dough piece which was passing beneath plate 25 moves on, the latter drops, actuating the valves 27 so as to exhaust all the cylinders, and thus allow plate 21 and fingers 47, 48 to return to their normal positions so that the sets of pans are again stopped and the dispenser is closed to retain a dough piece. In order to provide for placing either one or two dough pieces in a single pan, the blocks 51 are slidable longitudinally along rods 52 by means of screws 54, each turned by a handwheel 55, Fig. 4. Thus the two fingers can be placed in transverse alignment whereby they act together on each pan, or they may be staggered as shown, Fig. 4, so that upon one lifting of plate 25 fingers 48 stop a pan, and upon the next lifting of plate 25 finger 47 stops the same pan a little further forward so that two dough pieces are delivered to the same pan, finger 48 being trapped below the pan. A light spring 62 biases each finger to rise after a pan has passed over it. Specification 654,334 is referred to.

Title: A system for the cooling of mines or like chambers requiring ventilation
IPC: E21F3/00
Filed: 1923-07-02
Abstract: 222,559. Carrier, W. H., and Carrier Engineering Co., Ltd. July 2, 1923. Ventilating mines; air, heating and cooling; forced ventilation.-In a system for cooling mines &c., heat is removed from the incoming air by a heat-interchanger 5 at the bottom of the down shaft 2 and is transferred through centrifugal refrigerating apparatus 10, 11, 12 operated at pressures below atmospheric pressure, to a second heat-interchanger 9, at the bottom of the up-shaft 3, which gives this heat back to the air issuing from the workings. The air in its passage through the mine takes up heat from the workings and, as it leaves the interchanger 9 with its restored heat and saturated with water vapour, the outgoing column of air is much lighter than that of the incoming air and an up-draught is produced in the shaft 3. The interchanger 5 for cooling and dehumidifying the incoming air is preferably located in a chamber 8 communicating with the main passage 1 by a byepass 4, a fan 6 with a discharge nozzle 7 being employed to draw a portion of the incoming air through the heat interchanger 5. Water is circulated from the cooler 10 to the spraying nozzles 17 and back again by a pump 13 and pipes 16, 15, 14. A similar pumping system 22, 19, 20, 21 circulates the heated water from the condenser 12 to the'spraying nozzles 23 in the heat-interchanger 9 and returns it cooled to the condenser. The refrigerant is vaporized by the heat abstracted from the water in the cooler 10 from which it is withdrawn, compressed, and delivered by the compressor 11 to the condenser 12 in which it is condensed by the cooled water from the interchanger 9. Spaced zig-zag vertical plates 18, 24 may be provided in the heat-interchangers 5, 9 respectively to separate the free water from the air. The water accumulating in the first system can be used as make-up water for the second system, so that only a small additional quantity of make-up water is required for the second system.

Title: A process for the catalytic cracking of hydrocarbon oils
IPC: B04C5/24
Filed: 1954-06-11
Abstract: <PICT:0753782/III/1> In a process for the cracking of hydrocarbon oils in the presence of a fluidized bed of cracking catalyst particles, wherein the vaporous hydrocarbon products are withdrawn from the disengaging space of the reactor through a plurality of cyclone separators disposed inside the reactor, partially spent catalyst is continuously withdrawn from the fluidized bed and stripped with steam, and the vapours from this stripping operation are introduced into the disengaging space at a level above the cyclone separators so that they flow downward to, and then through, the cyclone separators and are withdrawn from the system, free from entrained catalyst particles, together with the vaporous hydrocarbon products.  The downward flow of the stripping gases to the cyclone separators eliminates the undesirable thermal cracking of hydrocarbon product vapours which takes place in the upper part of the disengaging space of conventional reactors.  In the reactor shown, partitions 7 extend across it and create two stripping zones A and B which are provided with steam lines 8, 9.  Spent catalyst flows from the fluidized bed 6 into these stripping zones through openings 12. Stripped catalyst leaves the stripping zones through standpipes 10 and 11.  The stripping gases reaching the tops of zones A and B pass through lines 23 and 24 into dome 25, and then enter the top of the disengaging space of the reactor.  Two first-stage cyclone separators 13, 14, and two second-stage cyclone separators 15, 16 are shown in the disengaging space; but in actual practice there are six such sets.  The vaporous hydrocarbon products from the fluidized bed flow upwards to inlet openings 17, 18 of the first-stage cyclones, while the stripping gases flow downwards to these openings from dome 25. The entrained catalyst is separated from the vapour mixture in the cyclones; and the catalyst, which collects in hoppers 19 and 21, is returned to the fluidized bed by dip pipes 20 and 22.  The vapour mixture is withdrawn from the second-stage cyclones through line 26 which pases through dome 25.

Abstract: 1384943 Spectral analysis of radio-active samples WALLAC OY 14 April 1972 [16 April 1971] 17412/72 Heading G1A The spectral analysis of radio-active sample e.g. in the form of a liquid scintillation sample is carried out by a photo-multiplier coupled to a plurality of discriminators D 1  to D n , which define a plurality of contiguous pulse amplitude ranges, each discrimator being connected to an indicator lamp I 1  to I n , whose brightness is proportional to the frequency of pulses in the particular discriminator amplitude range. The discriminators may be biased operational amplifiers having different threshold values which increase in accordance with an exponential function. And-gates having second inverting inputs to ensure an input pulse to the apparatus produces an output in only one amplitude channel. The differing lightnesses of the lamps thus provide a visual indication of the amplitude spectrum of the sample. Counts in one or more amplitude rayes may be made by connecting selected axis points C to sealers Sc.
