Title: Improvements in and relating to ceramic seals and method of making same
IPC: C04B37/02
Filed: 1947-07-24
Abstract: An intimate coating of titanium is formed on a ceramic surface to facilitate bonding the surface to a metal member or another ceramic member.  The surface is coated with titanium hydride and then heated, preferably in vacuo, to a suitable temperature to bond the reduced titanium to the ceramic.  Abutting ceramic surfaces may be treated in the same way and then bonded together, or metallic members may be soldered to a titanium coated ceramic surface.  This may be carried out by interposing a mixture of titanium hydride and solder between the ceramic and metal surfaces and then heating the assembly in vacuo or in an atmosphere of hydrogen.

Title: Improvements in air preheating means for locomotives
IPC: F23L15/02
Filed: 1923-08-07
Abstract: 202,305. Aktiebolaget Ljungstr÷ms Angturbin. Aug. 8, 1922, [Convention date]. Regenerators.-The air supply to the fire-box of a locomotive is heated by a rotary regenerator which, as shown at 14 in Fig. 1, is arranged to rotate in a vertical plane partly in the smokebox 13 and partly in the air conduit 15 leading from the front of the locomotive to the ashpit. The gases, &c., leaving the boiler tubes are drawn through 'the regenerator by a fan 4 in the stack. The entrance to the air conduit is funnelshaped, and provided with louvres 8 for regulating the air supply. In a modification, Fig. 2, the regenerator is arranged at 20 within the smoke-box, which is divided into separate compartments by partitions 23, 24. The smoke and gases are drawn through the upper part of the regenerator by a fan in the stack, while air entering at the front of the smoke-box beneath the partition 23 passes through the lower part of the regenerator and thence to the conduit 28 communicating with the fire-box. The upper front portion of the smoke-box is connected with a cinder collector 30. The front part of the smoke-box may be hinged to the flange 31, so that it may be removed for inspection purposes or for cleaning the boiler tubes. In a modification, the regenerator may be arranged in the smoke-box in advance of the smoke-stack. Fig. 5 shows a modification in which the regenerator 67 and exhaust fan 64 are driven from a common motor, e.g., a turbine 69 mounted on a frame 70 constituting an oil reservoir for lubricating purposes. The turbine drives through gearing 71, which may embody a pinion lubricating-pump, a shaft 72 geared by a chain, belt, or the like to a shaft 74 on which is mounted a roller 75 adapted to engage a band 76 on the regenerator. The oil pump mounted on the 'turbine shaft may supply oil to an oil-driven motor geared to the regenerator.

IPC: A21C11/18
Filed: 1970-04-28
Abstract: 1303520 Potato extruder L J ILINES 28 April 1970 [28 April 1969] 20221/70 Heading B5A [Also in Division F2] In apparatus wherein mixed potato dough and water is vertically downwardly extruded, by a manually actuated piston impeller, through a multi-orifice die plate wherefrom it is severed for subsequent frying by a manually pivotable cutter, the piston is incrementally downwardly displaced by engagement, Fig. 3, of the rod 19 thereof frictionally within an opening 34 at one end of a member 32, when this is downwardly tilted from the horizontal and then downwardly displaced, against a return spring 40, by engagement of a follower 36 at the other end of the member 32 by an eccentric 45 which is manually rotated by downward movement of a handle 49, 50. The member 32 is mounted within an opening 31 of a housing 13, 6, supporting the extrusion cylinder, and upon release of the handle 49, 50 the spring 40 upwardly displaces the member 32 about the rod 19, with simultaneous rotation of the eccentric 45, to its starting position in abutment with a collar 42 which is screw threadedly adjustable within the housing 13, 6 to vary the stroke of each incremental discharge by the piston. In the Fig. 3 embodiment, the frictional engagement of rod 19 is effected by a hardened washer 35, the opening whereof is axially perpendicular to the member 32 which is tilted from the horizontal to effection frictional engagement. Displacement of the rod 19 beyond the location at which the extrusion cylinder is exhausted is prevented by an upper portion of the rod 19 being reduced in diameter below that at which the opening 34 will frictionally engage. To facilitate removal of the extrusion cylinder, for cleaning and recharging, the piston is raised clear therefrom and retained in this position by frictional engagement of the shaft 19 within the opening 34, with handle 49, 50 locked in a lower position. In the Fig. 6 embodiment the member 66 comprises a hardened steel plate provided with an opening 67  which is axially non-perpendicular thereto, so that the plate 66 is tilted upwardly from the horizontal as shown when upwardly returned by the spring 40 and not frictionally engaging the rod 19, this alignment being ensured by the angled end 78 of a sleeve 77 which is slidable along the rod 19. In this embodiment, the eccentric comprises a rod 69 spanning between rotary hubs 70 and the bevelled portions 75, 76 engage across the width of the plate 66.

Abstract: 793,622. Automatic speed control systems. IGRANIC ELECTRIC CO., Ltd. July 16, 1954 [July 17, 1953], No. 20812/54. Class 38 (4). [Also in Groups XXXVII] In an automatic control system for a characteristic of electrical apparatus having electrical power supplied separately to two of its elements, a signal dependent on the value of the characteristic, the desired value of the characteristic, and one of the powers supplied, controls both power supplies, and means responsive to the value of the characteristic are provided to render the control of one of the power supplies ineffective over a portion of the range of values of the characteristic. To maintain constant the speed of a D.C. electric motor 1, the voltage of a D.C. tachometer generator 112, driven by the motor, is applied in opposition to a D.C. reference voltage, obtained from a potentiometer 110, to the grid circuit of a rectifier valve 60 controlling the supply from A.C. mains L3, L4 to motor armature 3. When the armature voltage rises above a predetermined value, a valve 52 is rendered conductive so that above a predetermined speed, control winding 15a of a saturable reactor 15 is energized in dependence on armature voltage to reduce the energization of motor field winding 5 by phase-shift of the voltage applied to the grid circuit of a rectifier valve 30 controlling the supply from A.C. mains L1, L2 to motor field winding 5. When the armature current rises above a value determined by the setting of a potentiometer 86 the output of a rectifier 23 associated with an armature current transformer 62 is sufficient to render a valve 84 conductive so that volt-drop in a resistor 88 is effective to reduce the armature supply and thereby limit armature current. In machine tool drives the speed of motor 1 may be controlled in dependence on the speed of a process line by operating a switch 122 to introduce a tachometer generator 120 driven at the speed of the process line.

Abstract: 186,312. Aktiebolaget Separator. Sept. 22, 1921, [Convention date]. Cleaning drums.-A centrifugal separator bowl A is cleaned from silt deposited during the process of separation by means of a jet of steam and water from the injector D. The bowl is mounted upside down on the frame B on the bearing C and the injector D is mounted so that the jet strikes the bowl in a direction inclined to the vertical and horizontal. The jet causes the bowl to revolve and the silt and liquid fall downwards. In a modification, a conical drum is washed by a jet placed above it. In the arrangement shown in Fig. 5, an inset of conical discs His mounted so that it can rotate while being washed by the jet from the injector. The spindle is threaded so that the discs are moved axially during the washing process. This axial motion may be obtained by means of gearing actuated by the jet. The apparatus may be enclosed in a casing E. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the water injector is rotatably mounted instead of the part to be cleaned. This subjectmatter does not appear in the Specification as accepted.
