A reglet for holding flashings comprises a bracket part 14 carrying a channel 12 into which, a lip 36 on the flashing 32 can be inserted, the channel having flanges whose inner surfaces diverge at an acute angle outwardly of the channel, the terminal portion of the upper flange 22 having an inner surface which is at an obtuse angle to the rest of the surface of that flange so as to co-operate with the lower flange to constitute a restricted entrance to the channel. The flashing 32 is formed of resilient sheet material so that its lip 36 engages with a snap lock action within the channel 12. The bracket 14 is fixed to the wall with the intermediary of a moisture excluding sealing compound 30. In modifications, Figs 3 and 4 (not shown) the bracket parts are designed to be built into the space between blocks, or incorporated in an overhanging plaster wall.

The lever is formed with two arms 16 which are guided in slots 25<SP>1</SP> formed in plates 24, 25 secured to the body of the solenoid. In operation, when the solenoid is energized the lever, together with the funnel, are raised until the end of the lever abuts the bottom of the slot 16 in the plate 24 and the funnel engages with the collar 12, continued upward movement of the armature causing the valve to be raised to the open position and so dispense the measured quantity from the measuring chamber 16. In a modification, the solenoid may be replaced by a piston-and-cylinder device actuated by compressed air.

Abstract: 1,193,493. Extruding; making turbine blades or wire. WHITTAKER CORP. 27 June, 1967 [27 June, 1966], No. 29687/67. Headings B3A and B3P. [Also in Division F1] A composite structure is formed by assembling a set of cladded filaments 10 into a bundle, heating the bundle and extending it through a die to form a cellular matrix. The bundle is placed in a canister 16 and the canister is evacuated to 10<SP>-3</SP> torr. before heating. The core of each filament may be molybdenum, titanium, tungsten, nickel, cobalt or alloys thereof. The shell may be nickel-chrome, iron-chromealuminium, hafnium based tantalum alloys, refractory oxides or organic material such as plastics. The shell may be applied as a tube around the core or by plasma-jet spraying. The canister 16 may be of the same material as the shell or it may be expendable. The surfaces of the filaments and the canister which are to be bonded together are preferably cleaned with ethyl alcohol. The surfaces may be cleaned by machining and the parts assembled in a protective atmosphere. A solid copper guide 26 is welded to the front of the canister 16 to guide the canister and also act as a lubricant. During the extrusion the cores of the filaments are deformed into polygonal cross-section. If the core and shell materials do not readily bond a diffusion layer (36), Fig. 6 (not shown), is interposed between them, for example, a layer of aluminium or magnesium oxide between a molybdenum alloy core and an ironchrome-aluminium-yttrium shell. Each filament may be multi-cored. The composite billet may be extruded to form composite wire or through a shaped die with the cross-section of a turbine blade. Alternatively the billet may be made up of a turbine cross-section shaped canister 44 surrounded by a filler 46. The filler is removed by acid after extrusion. When the extruded product has to be cut into shorter lengths the ends of the cores are protected from contamination by spacers (58), Fig. 9 (not shown), of shell material.

Title: Improvements in automatic gauge control systems

IPC: B21B37/16
Filed: 1957-09-26
Abstract: 901,182. Automatic thickness control systems. RANK PRECISION INDUSTRIES Ltd. Sept. 3, 1958 [Sept. 26, 1957], No. 30196/57. Class 38 (4). In an automatic control system for maintaining a dimension of a longitudinally-extending material within a tolerance band, a feed-back quantity inversely proportional to the speed of the material emerging from a forming device is caused to act in a manner tending to reduce the loop gain, defined as the rate at which a correction in response to a given error is applied, so that the rate of correction applied in response to a given error outside the tolerance band is made proportional to the speed and the effect of transportation lag is counteracted. As shown, Fig. 2, the thickness of a material 6, reduced by rolls 2, 2a, is detected by an electrical thickness gauge 7, the output signal of which through an amplifier 8 and relay controller 9 operates a screw-down motor 4 to correct deviation in strip thickness. Signals representative of the speed of the strip, sensed by a tacho-generator 11, and the speed of the screw-down motor, sensed by a tachogenerator 10, are fed to an analogue divider 12, the output of which is proportional to strip speed and inversely proportional to the screw-down speed. The output signal from the analogue divider is fed as a feedback signal to the amplifier 8 so as to turn off the controller 9 at an increasing rate as the speed of the strip decreases. In another embodiment, Fig. 4, the tachogenerators 10, 11 are interconnected by a transistorized arrangement and the feed-back signal is derived from the output of an armature 10a of the tachogenerator 10. The output from an armature 11a of the tachogenerator 11 is fed to the input of a groundedemitter transistor 17 in series opposition with a reference voltage across a tapped portion of a resistor 16. The, output of transistor 17 is direct-coupled through a Zener diode 19 to the input of a transistor 21, the collector circuit of which includes field windings 10b, 11b of the tachogenerators in series. The tapping on the resistor 16 is adjusted so that when armature 11a is stationary, the transistor 17 is biased near to the cut-off point. Movement of the material causes the output from the armature 11a to increase so reducing the bias on transistor 17 and increase the collector current through a resistor 18 and consequently reduce the bias current of the transistor 21 and so reduce the excitation of the tachogenerators so that the output from the armature 10a is rendered inversely proportional to strip-speed. In a further embodiment, Fig. 3, not shown, the voltage from the armature 11a is compared with a reference voltage in a comparator, the output of which, through a current amplifier, energizes the series-connected field windings 10b, 11b.
