Abstract: 328,055. Stratton, J. F. O. Jan. 28, 1929. Pulverulent and small fuel furnaces ; grates. -Two grate frames 53, 58 arranged at the open bottom 21 of a combustion chamber 14 and spaced apart to form a nozzle 64 through which an air blast is forced upwardly into the furnace from the ash-pit 26, are reciprocated bodily transversely of the opening to vary the position of the nozzle. The fuel is fed by a screw 17 through a spout 18 in the upper part of the front wall 10 and falls to the throat 21, being burnt while in suspension. The force of the blast is such that non-combustible material is allowed to fall through the space 64 to the ashpit while the combustible material is maintained in suspension. Sets of slicing bars 67, 68 resting on the grate frames are reciprocated oppositely to the grate frames. Hollow metal castings 29, 30 form the sides and ends of the throat 21 and are supplied with compressed air by a conduit 40, the air being discharged through nozzles 33 into the ashpit to maintain the pressure therein. A small amount of air is allowed to escape between the lower and inner walls of the casings 29, 30 for cooling purposes, and the inner walls of the castings are corrugated. Fixedly mounted below the throat are spaced tracks 44 on which run grooved wheels 46 carrying a movable set of tracks 48 connected by a link 52 to an arm 85. The grate frame 53 is fixed to the tracks 48 while the grate frame 58 is provided with wheels 61 running on the tracks 48 and is connected by links 66 with an arm 88. The slicing bars 67, 68 are hooked at their rear ends over horizontal shafts 71, 72 extending along opposite sides of the throat and carried by spaced arms 73, 76 connected by links 75, 78 with arms 87. 86 respectively. Pivoted scraper members 80, Fig. 2, prevent fuel or slag being carried out on the slicing bars.

Abstract: 429,525. Toy locomotive reversing- mechanism; electromagnetic switches. HORNBY, F., 236, Binns Road, Old Swan, Liverpool. Jan. 30, 1934, No. 3084. [Class 132 (iii)] [See also Group XXXVII] A toy electric locomotive has electric reversing mechanism thereon operated by an element movable on breaking a track circuit, the movement of the element being damped so that no reversal takes place on the circuit being broken due to track inequalities &c. When the remote control switch 44, Fig. 6, is broken and made, the polepiece 13, Fig. 1, pivotable at 17 with respect to the electromagnet 12, 16, moves to the right under the action of the spring 18 and moves with it the slide bar 25 on which is pivoted the spring controlled pawl 27, which, on return of the slide bar 25 on making the switch 44, engages one of the recesses 34<a> or 34b and rotates the disc member 29 carrying the commutator 31 for reversing the current through the armature 3. The commutator 31 comprises a disc 34 on which are mounted conducting segments 35, 36 and a conducting plate 37 with which engage contact fingers 39, 41 and 40 carried on an insulator strip 42. Movement of the polepiece 13 to the right is damped by the weight 20 secured on a bolt 21 between a pair of arms 22 extending from the top of the polepiece 13, so that complete movements of the polepiece 13 due to inequalities in the track &c. are prevented. Spring or dash-pot damping means may be used instead of a weight. The damping means may be adjustable. In a modification, instead of the polepiece 13 being movable, the electromagnet is left complete and an additional armature is mounted in proximity thereto and controlled by a spring or gravity with the addition of damping means as above.

Title: Improvements in and relating to the beheading of fish
IPC: A22C25/14
Filed: 1951-02-09
Abstract: 681,879. Fish, beheading and gutting. FEDERATIONA NARODNA REPUBLIKA JUGOSLAVIJA - GENERALNA DIREKCIJA ZA MASINOGRADNJU VLADE FNRJ. Feb. 9, 1951 [Feb. 18, 1960], No. 3241/51. Class 28 (ii). Fish are cut at the back of the neck and the head and attached guts are then pulled away from the body by hand placing each fish in one of the troughs or transverse channels 1 of a conveyer whereby fish are conveyed broadside or against a fixed knife 7 accommodated longitudinally in slots or recesses 3 in each trough. At the same time each head in turn meets the point of a long fixed spike 8 and so becomes impaled thereon, the spike being so bent away from the knife that the heads are partially drawn away from the body. The body is similarly drawn away from the head by a ramp-like blade 7a, Fig. 11, fixed on one side of the knife. Finally the body drops away by gravity from its channel 1 to fall into a delivery shoot. The heads which become impaled on the spike 8 slide along it to contact another fixed knife 9 which cuts them free of the spike so that they drop, still with their guts attached, into another receptacle. The forward end of each trough is cut away on the skew as in Fig. 4 (Plan) to facilitate the falling away of the severed heads. Fig. 8 shows the knife 7 at the beginning of a cut which begins above the back bone but not into the belly cavity. Quick positioning of the fish in each channel is facilitated by an abutment 6a, Fig. 6, against which the operator presses the fish nose just before dropping it in the trough. A regulator 6 accommodated in the slots 4 is also provided for a similar positioning in the trough itself both 6a and 6 being adjusted as required to suit the average length of fish head being operated on. 6 and 6a may also be inclined to assist in feeding the fish into the individual troughs. In a modification the long spike 8 may be bent laterally and downwardly from the knife to pull the heads in these directions. In this case the slot 4 opens downwardly as in Fig. 5 (not shown) where the slot 3 also opens downwardly so that the back of the knife abuts against the upper closure of the slot 3, and the knife cuts downwardly the fish being placed back upwards in the troughs. After discharge of the fish heads and body, another beheading knife may be arranged further along the run of the conveyer. Several such beheading stations may be arranged along an endless conveyer.

Abstract: 698,309. Refrigerating. CARRIER ENGINEERING CO., Ltd. Feb. 8, 1952 [Aug. 7, 1951 ], No. 3437/52. Class 29 In a refrigerating system of the general type disclosed in Specifications 639,413,639,416 and 658,914, in which the refrigerant is water and an absorbent in the form of a saline solution is circulated by an ejector 18 actuated by a pump 8, the solution flow is not interfered with and the system is so operated that, at full load, the concentration of solution leaving the generator 6 and the temperature difference between the condenser 7 and the solution leaving the generator are maintained at predetermined maxima and, at partial load, the condenser temperature is increased and the concentration of solution leaving the generator is reduced. As shown in Fig. 1, the pressure of steam for heating the generator is maintained constant by a valve 36 and the flow of cooling water to the condenser is regulated by a valve 40 supplied from a pipe 60 with compressed air the pressure of which is varied both by a venting flap 50 operated by a thermal element 45 responsive to the temperature of chilled water leaving the evaporator 4 and by a further venting flap 50 operated by a thermal element 46 responsive to the temperature of the condenser system. In a modification, Fig. 3, valve 40 is located between a condenser shell 104 separate from the generator shell 102 and the evaporator 4 so that, when the valve 40 is throttled, the level of condensate rises in the condenser shell 104 to cover more of the cooling tubes and so reduce the effective heat transfer surface and increase the condensing temperature.
