S., Kelda, Baltasound, Shetland, and INDUSTRIAL COMBUSTION ENGINEERS, Ltd., Cecil Chambers, Strand, London. Feb. 28, 1930, No. 6635. [Class 106 (ii).] Liquid-level pressure gauges.-A differential gauge for use with flow meters comprises a U-tube in one leg of which is pivoted a float so located that it traverses a relatively large arc for a small change in liquid level near the position corresponding to " zero," but traverses a small arc for a like change in level near the position corresponding to maximum reading. The pipes 3, 4 from opposite sides of a constriction in a pipe communicate with the cylindrical limbs 7, 11 of a U-tube gauge of which the axis of the limb 11 is horizontal. A cylindrical float 14 is pivotally supported in a carrier 16 mounted on pivot 18. A stop 19 prevents the float being vertically under the pivot 18 in the zero position. A screwed displacer 33 enables the mercury level to be adjusted. The swinging movements of the float are transmitted by a magnet 15 in the float to a coaxial and coaxially pivoted magnet 21 to which a pointer 26 is attached which moves over a scale 27. The thin partition 12 and the cover 13 are made of non-magnetic material. Float valves 36, 37 at the bottom of the limbs prevent mercury being blown out of the gauge on excessive pressures. A shaped piece 20 may be inserted in the limb 11 to enable the movements of the float to conform to a straight line law.

Title: Improvements in or relating to hinged barrel gun mechanisms
Inventor: CLAESSON ERIC
IPC: F41A17/60
Filed: 1953-03-11
Abstract: 725,582. Smallarms; safety devices. HUSQVARNA VAPENFABRIKS AKTIEBOLAGET. March 11, 1953, No. 6736/53. Class 119. A drop-down gun with a self-cocking hammer has a safety bar 26, Fig. 3, longitudinally slidable in a bearing 27 and at the opening of the gun is automatically moved rearwardly by the barrel locking bar 7 to occupy an inoperative position relative to the sear 20 before the cocking of the hammer 13, Fig. 1, and on closing of the gun is automatically moved forwardly to occupy a safety position wherein the sear 20 is locked by interengagement of lugs 23, 33 on the sear and safety bar respectively. A slidably mounted locking bar 7, Fig. 3, co-operating with lumps 5, 6 has a slot 8 for an arm 9 on a shaft 10 which is turned by an opening lever 11 against the action of a spring 12. As shown the gun is double barrelled and each sear 20, Fig. 1, pivoted at 21 and pressed by a spring 22 engages a detent 18 in a hammer 13 and at its rear end has a lug 23 in the path of movement of a trigger 25 pivoted at 24. The safety bar 26 common to both hammers has at its forward end a driver 35 embraced with longitudinal play by claws 34 on the rear end of the locking bar 7 and has lateral lugs 33 which in the safety position shown in Fig. 1, is situated immediately above the lugs 23 of the sears. The play of the driver 35 within the claws 34 permits the bar 26 to be pushed forward by means of a lever 29, Fig. 3, and thumb piece 30 acting against a spring 31 to the unsafety position wherein the lug 33 is moved forwardly of the sear lug 23. On turning the lever 11 for braking the barrel the locking bar 7 together with the safety bar 26 is moved rearwardly from the unsafety position to the inoperative position shown in Fig. 3, the lug 33 passing above the sear lug 23. On braking the barrel the hammer is cocked during a turning movement of the sear 20 which is permitted by the safety-bar 26 in its operative position and on closing the barrel, the locking bar 7 is returned to its locking position by the spring 12 and the claws 34 engaging the driver 35 pull the safety bar 26 forwardly into its safety position wherein it is held by the lever 29 and spring 31. The safety bar may be provided with a lug 36 adapted to lock the trigger in the safety and inoperative positions. Instead of pulling forward the bar 26 by means of the parts 34, 35, these may be omitted and spring means used to urge the safety bar 26, Fig. 3, to the left when it is to the right of its safety position.

A patterned fabric comprises a base yarn and an extra, discontinuous yarn knitted in at random intervals. The yarns may be of the same material, and may be continuous filament or staple fibre yams; their properties such as dye uptake and cross-section may differ. The extra yarn is fed by nip rollers 7, 8 and an air jet 10, 11 at a slower speed than the base yarn and broken, as the yarn tensions, on a cutting edge 12 at the end of the jet. The feed rate is varied by varying the feed speed or nip pressure, or by opening the nip. In one embodiment either or both rollers include 'flats'. In a further embodiment the driven nip roller comprises inner and outer portions joined by a spring or pin and slot connection so that the outer portion oscillates, varying the feed, when the yarn breaks.

Title: Delay pickoff circuit
IPC: G01R13/32
Filed: 1972-02-14
Abstract: 1341166 Delayed triggering of sweep generators; cathode-ray tube circuits TEKTRONIX Inc 14 Feb 1972 [17 March 1971] 6770/72 Headings H3T and H4T Triggering of an oscilloscope sweep generator is delayed (e.g. to provide an expanded display) by a circuit in which a delay ramp initiated by a triggering signal is compared with a variable reference, the zero setting of the reference enabling the triggering signal to by-pass the delay circuit in order to avoid residual delays. The triggering pulse at 24 switches a tunnel diode 28 which initiates operation of a delay sweep generator 10. When the sweep reaches the value of a delay setting at 16 a comparator 14 switches a tunnel diode 54 which switches a further tunnel diode 76 to initiate the oscilloscope sweep. At the end of the delay ramp a signal is fed to "hold-off" terminals 36, 62 or 84 to reset the tunnel diodes. At the zero delay setting of 16 the comparator provides sufficient biasing current to the tunnel diode 54 to permit it to be triggered by diode 28 so that the residual delay in the delay path is avoided. An amplifier 94 provides a ramp 94 which smooths the changeovers from direct to delayed triggering paths.
