Title: Improvements in or relating to vapour generators
IPC: F22B1/02
Filed: 1958-04-09
Abstract: 841,656. Heating steam generators by hot gases. WESTINGHOUSE ELECTRIC CORPORATION. April 9, 1958 [April 10, 1957(2)], No. 11200/58. Class 123(2) A steam generating unit consists of a cylindrical pressure vessel 12 closed at the top by a dished head 18 having a steam outlet 36 and at the bottom by a dished head 16 divided by a mid-partition 30 into heating fluid inlet and outlet chambers 26, 28. The chambers are separated from the vessel 12 by a tube plate 44 in which are held the tube ends of a bank 42 of nested U- tubes extending upwardly within the vessel, each U-tube connecting the chambers 26, 28 for flow therebetween of the heating fluid, for example the coolant from a nuclear reactor. Enclosing the tube bank to form a steam generating chamber 20 is a cylindrical plate 48 spaced inwardly from the pressure vessel wall to provide an annular downcomer space 50. A conical plate 78 connects the plate 48 to a short cylindrical riser 68 containing vanes 70 which, in operation, impart a spinning movement to the steam-water mixture rising from the chamber 20. Above the riser 68 is a chevron separator 74. A baffle 72 depends from this separator and surrounds the riser 68 to form an annular space through which water separated centrifugally by the vane 70 returns to an annular water storage space 24 between the plate 78 and the vessel wall. Water removed by the chevron separator and by a final separator 75 also returns to this space. Feed-water enters by a ring pipe 38 having holes in its underside to direct the feed-water downwardly into the downcomer space 50.

Title: Receiving device for sound echoes
IPC: G10K11/00
Filed: 1922-04-21
Abstract: 180,987. Atlas-Werke Akt.-Ges. May 31, 1921, [Convention date]. Determining bearings and distances acoustically.-Apparatus for detecting sound echoes is so located that direct sound from the transmitter influences it to a much smaller extent than the echo from the reflecting surface. The invention is described as applied to a device for measuring the depth of the sea. The diaphragm M of the direction detector E is mounted in the plane of the direct sound beam St, from the transmitter S, and is thus practically uninfluenced by the direct sound, but the reflected beam St2 from the sea-bed F strikes the diaphragm M at an effective angle approximating to the normal.

Title: Starting system for an engine
IPC: F02N11/08
Filed: 1973-03-08
Abstract: 1399948 Starting prime movers FMC CORP 8 March 1973 [17 March 1972] 11280/73 Heading H2H Apparatus for starting an internal combustion engine comprises two batteries and a controller remote from the engine by means of which either of the batteries can be selected and used to energize the engine starter motor together with a further controller situated adjacent the engine and which may be used to carry out the starting of the engine. A starting system for an I.C. engine has two batteries A, B, a starter motor 22 and a controller 40 remotely situated from the remainder of the apparatus. Operation of the controller 40 energizes the equipment 28, 30 normally associated with the engine and selectively energizes the coil 32 of contactor 24 or 26 to close the associated contact 34. Thus according to which coil 32 has been energized battery A or B will be connected to the starter motor 22. The system further comprises a controller 50 secured to the engine and which is provided with two switches 52, 54. The switch 54 selects the battery to be used by use of the contact 70 and connects the associated contactor coil 32 to the selected battery by the contact 62. Having selected the battery by the switch 54 operation of the switch 52 to close contacts 64, 66 will energize the equipment 28, 30 over the contact 64 and energize the starter motor 22 over the contact 66. After the engine has started, release of the operating plunger of the switch 52 causes the contact 66 to open to de-energize the starter motor 22 but the contact 64 will stay closed to maintain the energization of the equipment 28, 30. The switches 52, 54 are housed in a sealed unit which is attached to the engine and are intended for use in emergencies only.

Title: An improved dental flask and method of using the same
IPC: A61C13/16
Filed: 1926-04-30
Abstract: 275,305. Walker, E. E. April 30, 1926. Dental flasks.-A dental flask is provided with means for indirectly transmitting the pressure in the vulcanizer to the material in the mould whereby the vapour in the vulcanizer is prevented from penetrating the plaster investment and coming into contact with the material in the mould. The flash may comprise two parts a, b, Fig. 2, held together by bolts c engaging lugs d, and containing the plaster mould e. The mould cavity f communicates by means of a sprue g with a hole g' in the flask. The hole g<1> is sealed with a material, such as putty, which is impervious to the vapour in the vulcanizer and is plastic enough to flow at the vulcanizing temperature in order to transmit the pressure to the material in the mould. A groove, extending around the flask may also be provided with sealing material and a protecting band k may be fitted. Instead of exposing the flask to the vapour of the vulcanizer, the flask may be placed in a gas-tight collapsable envelope of rubber or thin sheets of lead, tin &c. containing a dry gas and disposed in the vulcanizer. The flask may be arranged in a gas-containing vessel o, Fig. 4, which is closed by a piston q exposed on its outer face to the pressure of the vulcanizer, or a column s of mercury may replace the piston as in Fig. 5. The liquid in the vulcanizer may be alcohol or alcohol and water, or two immiscible liquids having additive vapour pressures, or it may consist of water in which an alkali bicarbonate, such as sodium bicarbonate, is dissolved.
