Title: Apparatus and method for generating x-rays
IPC: H05G1/34
Filed: 1973-12-27
Abstract: 1444109 Automatic control of x-ray generators NIHON DENSHI KK 27 Dec 1973 [27 Dec 1972] 59832/73 Heading G3N An electron beam is scanned over a target to produce x-rays. A beam control signal is derived corresponding to the sensed scanning velocity and is used to prevent damage to the target by excessive irradiation. In the embodiment of Fig. 1, electrons pass from a filament source 2 to a target 7 by way of a Wehnelt cylinder 3, anode 4, focusing lenses 5, 6 and scanning deflection coils 10,11. X-rays from the target pass through a pinhole 14 and object 15 to a detector 16 with an associated display tube 18. The amplitude and frequency of the scanning signal fed to coils 10, 11 by an amplifier 12 are measured by detectors 19, 20, output signals from which are multiplied together in a circuit 21 to produce a scanning velocity signal forming a control signal.. The bias voltage supplied to the filament 2 and cylinder 3 by a source 22 is adjusted by the control signal so that the electron beam current is reduced if the scanning velocity decreases. The control signal may also be used to vary the spot diameter by adjusting the current supplied to the lens 6, and to control the filament temperature. The output from multiplier 21 may be compared with a reference signal to produce a pulse which cuts off the electron beam if the scanning velocity falls below a predetermined value, Fig. 2, (not shown). The scanning velocity may alternatively be determined by differentiating the output signal from amplifier 12, Fig. 6 (not shown). In other embodiments, Figs. 3-5 (not shown), an auxiliary lens for enlarging the spot, or a deflector for rapidly scanning the beam or diverting the beam away from the target may be energized if the scanning velocity falls below the predetermined value.

Abstract: 1278540 Reinforced tubes CONTINENTAL GUMMI-WERKE AG 17 Dec 1970 [17 Dec 1969] 59856/70 Heading F2P In a method of making a rubber or plastics hose, which may have an outer cover 5, at least one reinforcing stocking-like ply 6 of variable shape is radially dilated, fitted over an inner tube 4 and stretched axially to contract the ply on to the tube surface. As shown, the ply 6, which may be of textile fabric, is knitted on a mandrel 8 and compressed axially by a hollow tube 9 to remove it for fitment on the inner tube 4 which is supported on another mandrel 7. The ply is anchored at one end to the inner tube by a circlip (10) (Fig. 2, not shown), the other end being clamped after stretching the ply. The inner tube 4 and the outer cover 5 may be of elastomeric material such as natural and synthetic rubber mixtures which upon vulcanization and subjection to pressure and heat treatment assume an elastic condition.

Title: Improvements in or relating to electric immersion heaters
IPC: A47L15/42
Filed: 1968-12-23
Abstract: 1,244,870. Immersion heaters. ELPAG A.G. 23 Dec., 1968 [28 Dec., 1967], No. 60954/68. Heading H5H. In an electric immersion heater comprising a heating element 2 whose cold ends 1 pass in sealing relationship through an elastomeric sealing element 3 mounted in an opening in a tank wall 6, the element 3 has a flange 5 resting on one side of the tank wall 6 and at least one blind aperture 4 which is open on the said one side of the tank wall and whose bottom is located on the other side of the tank wall, the aperture or apertures 4 accommodating a fixing element 7 which presses the side walls of the sealing element 3 into sealing relationship with the opening in the tank wall. The fixing element comprises two angled plates 8 joined by a deformable strip 12. The plates 8 have lugs not shown which co-operate with the ends 1 of the heating element 2 to force them into engagement with the rounded ends of aperture 4 and deform elements 3 when the fixing element is secured in position. The fixing element 7 is placed in aperture 4 and plates 8 are pivoted towards one another about edges 9 to form a bead 15 on the sealing element 3 which seals the rim of the tank opening. At the same time strip 12 is permanently deformed. An earth terminal 13 is provided on the fixing element 7 which makes good electrical contact with the metal sheathed heating element 2. The fixing element 7 and sealing member 3 may be inverted so that they are accessible from within the tank (Fig. 3, not shown). In Fig. 7 (not shown) the plates 8 are pivoted to cause sealing element 3 to make a fluid-tight seal with the edges of the tank opening by screwing a bolt, which passes through a clip with wedge-like surfaces, into a nut held captive between the plates 8. The heater may be used in dish washers, washing machines or hot-water dispensers. A temperature sensitive device (e.g. a thermocouple) may pass through the sealing element.

Patent GB-624513-A (GB)
Abstract: 624,513. Order-telegraph signalling-apparatus. THORNTON, A. A. (Nordberg Manufacturing Co.). Aug. 20, 1946, No. 24796. [Class 118 (ii)] A ship's telegraph system in which the movement of an engine control lever actuates the bridge telegraph is characterised in that the control lever is connected by an endless cable to an engine-room indicator and this in turn is connected by an endless cable to a pointer on the bridge telegraph. Movement of the bridge telegraph lever 17 to indicate an order turns shaft 14 and a pulley 18 keyed thereon, which by means of a cable 19 turns a pulley 25 of the engine-room telegraph and a shaft 23 and pointer 24 keyed thereto. The attention of the engine-room staff is attracted by first moving the lever 17 past its central position, when a hammer 38.on shaft 23 strikes a bell 39. When the engine control lever 32 is moved to comply with the order indicated by lever 17 and pointer 24, a cable 29 rotates a double pulley 27, 28 to position an indicator 40 in register with the pointer 24. By means of a cable 34 the pulley 27 also rotates the bridge pointer 36 until it is positioned centrally with respect to the operating handle 17. Thus the correct operation of the engine control lever 32 is indicated on both the bridge and engine-room telegraphs.

Title: Improved outrigger
IPC: B63H16/06
Filed: 1979-01-25
Abstract: A rod (16) pivotally attaches to the side of a boat (14), extends outwardly therefrom, and connects with the free end of an oar (21) together with a restraint to provide a fulcrum remote from the side of the boat as the oar is pulled from fore to aft positions through a stroke. The restraining means, such as a forward link (19) extending outwardly from the side of the boat and a control link (18) connecting the outer ends of the rod (16) and forward link (19), allows aft movement of the fulcrum during the stroke. The position of the fulcrum together with its aft movement reduce the component of the force normal to the blade (32) that acts normally to the direction of motion thereby increasing the propulsive efficiency. Alternate restraining means, such as a gear and pinion or pulley arrangement or the like can be used to control aft movement of the fulcrum. <IMAGE>

Title: A Valve Member for a Molten Metal Metering Valve
IPC: F16K1/38
Filed: 1979-02-21
Abstract: A valve member 11 for a molten metal metering valve, includes an elongated stem 12 provided at one end with an inwardly tapering portion which, in use, co-operates with a valve seat to regulate the flow of molten metal through a valve orifice. The tapering portion is defined by a plug 15 formed separately from the stem 12 and removably secured to the stem 12, the plug 15 being composed of a material having a greater impact resistance than the material of the stem 12 at the operating temperature of the valve. The plug is attached to the stem by upsetting the end of the stem into a groove 16. When the tapering portion becomes worn, the plug 15 can be replaced without the need for replacing the entire valve member. A screw-threaded section 18 is secured to the stem at 17 by an adhesive. <IMAGE>

Patent GB-2062332-A (GB)
Title: Improvements in or Relating to Electric Bells
IPC: G10K1/064
Filed: 1979-11-08
Abstract: Current designs of electric bells normally use brass studs secured to an armature which come into contact with coil pole pieces during normal operation of the bell. The contact between the brass studs and the coil pole pieces can result in unwanted sound outputs. The present invention reduces these unwanted sound outputs by using studs of a softer non-magnetic material than brass or by replacing the studs by a sheet 38 of softer material suitably shaped to match the shape of the armature (Figure 3). An alternative is to remove the studs and fit a sheath of soft non- magnetic material over the ends of the coil pole pieces. <IMAGE>
