Abstract: 365,432. R÷ntgen-ray tubes. SIEMENS - REINIGER - VEIFA GES. FUR MEDIZINISCHE TECHNIK, 58, Mohrenstrasse, Berlin. April 13, 1931, No. 10854. Convention date, April 24, 1930. [Class 39 (i).] R÷ntgen-ray tubes with an inner wall 37 as described in Specification 364,568 or otherwise constructed to allow the mounting of earthed conductors near the discharge space, are rotated about the central axis and an axial cathode beam is deflected as at 45 to a non- axial point of the anti-cathode 33 by a stationary electromagnet 13, the coil, and, if desired, the core also, of which is earthed. The electromagnet is mounted on a lead-lined, brass centre 15 of a stationary ray-absorbing case in which the tube 36 rotates on ball-bearings 22, 41. The parts 9, 19 of the case are of porcelain with ray absorbents added. The cap at the cathode end carries axial and side brushes 43, 4 of carbon to supply the heating current to the cathode 35. Fan blades 28 at one end at least ventilate the space around the tube 36. The end and conical sides of the anticathode are covered with tungsten &c. The parts of the cathode, the focusing member 34 and the anticathode in the magnetic field may be of non-magnetic material such as chromiumnickel steel. The cathode and the anticathode are sealed to re-entrant glass tubes by elastic metal rings 7, 18 joined to collars 8, 17. At least one of the walls 36, 37 on the cathode side are of lead glass. The anticathode is cooled by fluid entering and leaving by channels 25,24. The pump for this fluid may rotate the tube by a flexible shaft 26 which may convey the fluid and may be coupled to the pump by a clutch, the clutch being released when the tube is worked without being rotated. In a modification, the tube is rotated by an electric motor with its rotor on the tube and its stator on the outer case. The motor may be mounted near the centre of the tube : if mounted near the cathode, it is insulated by a transformer in its circuit, a winding on the heating-current transformer then supplying the motor. To keep the deflection of the cathode beam constant, the deflecting field increases with the voltage applied to the tube, the magnet 13 being supplied through a transformer or rotary converter if the tube is supplied with alternating current, or through a control coupled to the voltage-regulator of the tube if the tube is supplied with direct-current.

Title: Improvements in Governing Mechanism for Compound Engines.
IPC: F01D17/00
Filed: 1918-07-08
Abstract: 117,626. British Westinghouse Electric & Manufacturing Co., (Assignees of Hodgkinson, F.). July 10, 1917, [Convention date]. Fluid relays; transmitting-mechanism. - Relates to governing means for compound engines or turbines having an emergency high - pressure supply for the low-pressure section. In a turbogenerator installation, Fig. 1, comprising a high-pressure turbine section 10 and two lowpressure turbine sections 11, 11<1> connected in parallel, in the event of a short circuit or other accident unloading, say the section 11', the sections 10, 11 continue in operation under load under the control of the governor 15 of the highpressure section, while the section 11<1> is automatically isolated by a governor 22 which is adapted first to cut off the fluid supply coming from the section 10 by closing a gate valve 20 when the speed of the section 11' becomes excessive, and then to admit sufficient live steam through a valve 23 to keep the section 11<1> running at normal speed. Excess fluid from the section 10 escapes through a relief valve 28<a>. Automatic stop governors 31 may be provided to operate separate valves 32 in case of emergency, and also to shut the gate valves 20, 21, so as to isolate the sections 11, 11'. When two or more generators are working in parallel, circuit breakers, located between the generators and between each generator and the bus-bar, may be opened by the automatic or manual tripping of the automatic stop governor through the intermediary of fluid and electric relays. A modification is described wherein a high-pressure turbine is connected with a duplex low-pressure turbine by a conduit having a gate valve such as 20. An application of the invention to the turbine described in Specification 17643/14, [Class 110 (iii), Turbines &c.], is described, and in this modification the gate valve may be closed by the governor of the initial section. The control of the gate valve may be effected by a governor 37<a>, Fig. 4, controlling a pressure-actuated device 39, Fig. 6, and a trip mechanism, 43, Figs. 4 and 5. Mounted on the governor lever 37<b> is a finger 47 adapted to release from a latch 46 a trip lever 45, and so allow a valve 44 to open and permit the space below a differential piston 60 to be exhausted. The piston 60 thereupon shifts a valve 52, admitting pressure fluid below a piston 49 which thereupon shuts the gate valve mounted on its rod. A switchboard control may be employed for varying the adjustment of the governor admitting live steam to the low pressure turbine, and the arm 37b may be provided with an electric contact 82 co-operating with contacts 83 so as to indicate by means of lamps 84 the position of the governor arm.

Title: Improvements in sluice, wedge, and the like sliding valves
IPC: F16K31/363
Filed: 1926-04-30
Abstract: 268,563. Williamson, H. P. April 30, 1926. Valves controlled by pilot or relay valves. - Automatic means for operating a four-way cock f controlling the motion of a piston b<2> actuating a sluice or like valve p to close the latter should the pressure in the main i fall below a predetermined amount comprises a box a divided into two compartments c, h, the lower compartment h communicating by a pipe j with the main i under control. A spindle d extends through the upper compartment c and has at its lower end which passes through a gland g in the web separating the compartments c, h an axial bore k and one or more radial holes l. The head of the upper compartments c has a seating c' for a mushroom, needle or other valve-like sealing collar n on the spindle d. The spindle d is connected mechanically to the four-way cock f and is urged downwardly by weights o or by spring means. When the valve p is open the collar n is held to its seating c<1> by the fluid from the main i which passes from the lower to the upper compartment via the holes k, l. If the pressure in the main i falls the rod d drops to operate the cock f to actuate the piston b<2> to shut the valve p, and the holes l in the rod d registering with the gland g cut off communication between the compartments c, h so that the valve p cannot open automatically when the pressure in the main i returns to normal. A cock r which is normally open drains any fluid leaking between the collar n and its seating c'. In a modification the top of the spindle d engages a weighted lever connected to the cock f. When the spindle d falls the weighted lever is released to operate the cock, which in turn operates the piston b<2> and shuts the valve p.
