Title: Improvements in or relating to underfeed mechanical stokers
IPC: F23K3/10
Filed: 1928-03-19
Abstract: 314,104. Thornton, A. A., (Parker, M. E.). March 19, 1928. Mechanical stoking. - Relates to underfeed mechanical stokers employing a fuel-feed screw and is described in connection with a hot water or steam system for heating buildings. The feedscrew working in a conduit 19 delivers fuel upwardly into a fire-pot 16 surmounted by sloping tuyere walls the space around which is in communication with a conduit 101 supplied with air under pressure by a fan 98. According to the invention, in order to prevent back flow of gases through the fuel conduit, air under a higher pressure than the blast is supplied to the fuel conduit by a pipe 106 which is tapped into the fan casing at a point of maximum pressure. The feed screw is driven through a variable-speed gearing forming the subject of Specification 314,324 and having combined with it the safety shear-pin driving-connection forming the subject of Specification 314,323. In addition the motor 95 is controlled jointly by a room thermostat 113 and a boiler-temperature thermostat 109. Thus, in operation, when the motor has been stopped the supply of heat will continue for a time from the boiler without further fuel supply while at the same time possible damage due to solidified clinker on an automatic start with the fire gone cut, is prevented by the safety shear-pin in the gear-box. The sloping tuyere walls have spaced vertical rear members 24 and top edges grooved at 35, Fig. 3, for engagement by L-section securing girders 33 and they rest on a T-beam frame 21 mounted in brickwork. The tuyeres themselves are of converging-diverging form.

A connecting member for connecting tubes or pipes comprises a tubular rubber body 1 having one or more undulations between its ends and tubular metal terminal members 2 inserted in the ends of the tubular body with at least the projecting portions of the members being externally threaded. The external threading may extend along the complete lengths of the members to promote gripping engagement with the body which may be-moulded on to the members. Alternatively, as shown the terminal members may be provided with saw-tooth gripping ribs 3. As a further alternative, the terminal members may be adhesively secured to the tubular body. In Fig. 2 (not shown), a connecting member having a single undulation between its ends is illustrated. The connecting member accommodates thermal expansion or misalignment of the pipes and tubes and absorbs vibrations.

Title: Means for taking samples, more particularly from shafts or bore holes
IPC: E21B49/08
Filed: 1929-03-14
Abstract: 330,317. Siemens - Schuckertwerke Akt.-Ges., Gutmann, V., and Steiner, L. March 14, 1929. Sampling liquids.- For taking samples of petroleum from predetermined depths in bore holes, the closing valves 6, 7 of a chamber 5 are controlled electromagnetically. The armature 15 of the solenoid 14, which is energized from the surface through conductors traversing the cable 2, is carried on a lever pivoted directly on or geared to the valve spindle 6. The two valves are connected by a rod 12 which passes through a pipe hermetically sealed to the end faces of the chamber 5. In a modification the armature of the electromagnet, at the required instant, trips the valve lever, which is then pulled over by a weight in the lower part of the casing first opening and then reclosing the valves; abrupt action is prevented by a dash-pot. The cable 2 is unwound from a winch on which is a device for measuring the distance. An electric motor may replace the magnet.

Abstract: 1,055,037. Resistors. CONSOLIDATED ELECTRONICS INDUSTRIES CORPORATION. Feb. 28, 1964, No. 8445/64. Heading HIS. An electrical resistor includes a relatively rigid core of insulating material, a conductive metal element on the core, and a moulded body of ceramic material over the conductive element and over at least a portion of the core, the moulded body comprising a vitrified matrix of glassy ceramic material and, within this matrix, particles of non-glassy ceramic material. An axial lead resistor is described which includes a rigid, ceramic core, e.g. of steatite, with conductive metal end caps secured to the core in a friction fit. A metallic wire is helically wound on the core between the end caps to which it is attached and a coating of the abovementioned ceramic material is moulded around the resistor. The glassy ceramic material originally exists as separate particles intermixed with the particles of non-glassy ceramic material; and upon subjection to appropriate temperatures, the particles of glassy ceramic material fuse together at contacting interfaces, whereby to form the vitrified matrix.

Abstract: 454,006. Dressing fish. LASSEN, W. O., 17, Glash³ttenweg, Lubeck, Germany. March 23, 1936, No. 8619. [Class 28 (ii)] A machine for cutting off the belly flaps of fishes and removing the heads together with the entrails comprises spaced endless chains 4 carrying transverse troughs 5, 8, the parts 8 of which are connected rigidly with the chains, the parts 5 being resiliently connected thereto. The fishes are laid bellies upward in the troughs 5, 8, the heads protruding so as to be engaged by a bifurcated knife 27 which is adjustably mounted on the machine frame at 28, 29. When the fish is to be decapitated only, the fish head passes into the fork 27b, 27<c>, but when evisceration is to be effected, the knife 27 is adjusted so that the point of the upper fork 27<a>, 27b pierces the flesh at about the backbone and the knife edge 27b cuts or tears downwards into the back flesh, the head being thus half severed from the body. The belly of the fish is engaged by the edge 6<a> of the knife blade 6 which co-operates with the upper sharpened edge of the trough part 8 in scissorslike manner to cut off the belly parts protruding above the trough. The head is deflected by a guide 25 into a slot 24 in the blade 6, the head being thus retained so that continued movement of the fish with the trough pulls out the entrails. The fish head is ejected by means, not described, and the fish body drops into a receptacle beneath the conveyer.
