[Class 135] A tap or cock which allows only a predetermined flow of fluid for a single actuation of the operating rod 2 however long the said rod is maintained in the valve-opening position has a floating lever 1 which is pivoted at one end to the rod 2, at the other end to a reaction device and intermediately to the valve spindle 10. The reaction device may be an escapement mechanism as shown in Fig. 2 or a dashpot. When the knob 3 is pushed inwardly, the valve 11 is opened against the fluid pressure in the inlet 5, the lever pivoting about the point x and the reaction device remaining substantially stationary. Subsequently the reaction device yields at a predetermined rate due to the inlet pressure acting to close the valve, the lever 1 pivoting about the point y. If the knob 3 is released before the time interval of the reaction device has elapsed, the valve closes immediately. The escapement mechanism, Fig. 2, comprises a rack 14 connected to a spring 18, and a pinion 15 fast with an escapement wheel 16 which has an escapement lever 17.

Title: Improvements in or relating to the manufacture of filiform single crystals
Inventor: NICKL JULIUS
IPC: C30B11/10
Filed: 1966-04-25
Abstract: Filiform single crystals of iron or germanium (whiskers) are produced by forming droplets of an impure form of the element in a reaction area maintained at a temperature between the melting points of the pure and impure element and producing the element in this area by a chemical reaction.  Droplets of the impure element are obtained either by heating a rod of the impure element in a plasma torch, or by using the impure element as electrode to form an arc through which hydrogen is passing.  The pure element is formed in situ by a reaction such as reduction or disproportionation and grows as whiskers on the drops.ALSO:Filiform single crystals (whiskers) are produced by forming droplets of an impure form of a substance, e.g. silicon, boron, or beryllium oxide, in a reaction area maintained at a temperature between the melting points of the pure and impure substances, and producing the substance in this area by a chemical reaction. Droplets of the impure substance are obtained either by heating a rod of the impure substance in a plasma torch, or by using the impure substance to form an arc through which hydrogen is passing.  The pure substance is formed in situ by a reaction such as reduction, disproportionation or oxidation and grows as whiskers on the drops.  Silicon whiskers may be made by heating an impure silicon rod and depositing pure silicon from a mixture of silicon tetrachloride or bromide and hydrogen.  Beryllium oxide is prepared using an ore and a mixture of beryllium halide and oxygen.

Abstract: 186,983. Ward, A., Gent, A. S., Pochin, F. H., and Pochin, H. S. July 6,1921. Lastin.g.-In an end-lasting machine, the toe head is supported so that it can move vertically and angularly and thus adapt itself to admit the bracing wire when this is applied after wiping over is completed. As shown, the toe head is mounted on a support 6 engaging by a slot 8 a spindle 9 fixed to the frame of the machine. The support 6 is adjusted angularly by a hand wheel on a screwed spindle 14 passing through a nut 15 provided with trunnions 19 normally restrained from travelling along slots 20 by hooks 21 operated by a handle 22. The spindle 14 engages a nut 13 swivelled in the end of an arm 7 depending from the support 6. The head is normally depressed by a link 17 co-operating with an adjustable spring 18, and may be raised' as desired by the operator depressing a pedal operating a vertically sliding rod 16. When wiping over is completed, the nut 15 is released to allow the head to be tilted by the bracing wire as this is pulled into position. This operation may if necessary be facilitated by the operator depressing the treadle operating the rod 16.

Title: Brakes for winding machinery

Abstract: 1502605 Winch brakes M B WILD & CO Ltd 25 April 1975 [26 April 1974] 18383/74 Heading B8B [Also in Division F2] A brake operating apparatus for dual parallel calliper brakes 11 of a winding drum 10 comprises dual parallel linkages 13, 14, 15, 17, 19, 20 between a main hydraulic brake engine 16 and the two brakes 11, and an emergency system for alternative brake operation, the dual linkages each incorporating a load cell (60) (Fig. 7, not shown) connected into a circuit which is arranged upon reception of significantly unequal signals from the load cells, to actuate the emergency system. The brake is normally operated by a manual lever 24 which through links 33, 32, 31 operates a main hydraulic brake control valve 35 to exhaust fluid from the brake engine 16. However, the valve 35 is restored to its original position by a compensating move-  ment of the link 31 provided through links 26, 27, 28, 29 and 30 whereby incremental brake  operation is controlled directly in accordance with brake lever position. The links 20 and 26 are connected to a rod 25 coupled to the main brake engine 16 through a spring box 22 and acted upon by weights 23. Fluid supplied along line 36 from an air, oil accumulator 40 associated with a dual fluid pump, passes through the control valve 35 and through a further valve 46 to the main brake engine 16, the fluid being exhausted from the engine 16 through line 37 when the valve 35 is set appropriately. The valve 46 is solenoid operated to dump fluid from brake engine 16 along a by-pass duct 47 and is actuated by a pressure sensor which maintains the pressure in supply duct 36. An emergency brake engine 21 which may be single or double is controlled through the respective one of two solenoid operated valves 43 controlling fluid supply from the accumulator 40 through a restrictor valve 44 responsive to the position of a lift cage being operated by the drum 10, and fluid exhaust to a reservoir 39. The emergency valve 43 is connected into an electrical circuit which monitors the cage speed and overtravel of the cage so that the emergency system can be actuated automatically on such occasions. The loads in the dual rods 15 are monitored by respective load cells connected into an electrical circuit having a meter and relays. The arrangement is such that if only one of the relays is actuated an audible warning is sounded but if both relays are actuated the warning is sounded and the emergency brake valve 43 is opened to brake the drum 10. The two links 17 incorporate interpenetrating forks with limited adjustable clearance therebetween to permit a predetermined amount of unequal movement whereafter both links move together. In another embodiment the electrical load cells are replaced by fluid systems providing pressure change signals.

Filed: 1929-06-17
Abstract: 335,179. Gillard, F. W. June 17, 1929. Photometric apparatus. - For the determination and comparison of light intensities, more particularly low intensities, a graduated light filter, or slot, or variable diaphragm is used by which the amount of light falling on a photo-electric cell not only serves as a means of measurement by giving a direct reading in candle-power, but is also so selected in degree and range of intensity that the photo-electric cell is caused to work on that part of its characteristic curve where the greatest change of indication is obtained with the minimum change in illumination. The light 9 to be measured is passed through a graduated filter 11, mounted on graduated rollers 12, on to a photo-electric cell 10 in circuit with an indicating galvanometer 14 as shown. The position of the filter is a measure of the intensity of the light 9. In a modification the cell is connected in the grid circuit of a three electrode valve and the anode current is utilized to serve as an indication. Alternatively the cell or the valve circuit may constitute one arm of a Wheatstone bridge. For the measurement of high intensities additional filters may be fitted in the light path.
