Title: Improvements in pressure gauges and in methods of calibrating pressure gauges
IPC: G01L9/08
Filed: 1960-07-20
Abstract: 910,898. Ultrasonic measuring devices. GENERAL DYNAMICS CORPORATION. July 20, 1960 [July 31, 1959], No. 25364/60. Class 40 (7). [Also in Group XXXVIII] A pressure gauge for measuring pressure pulses of short duration comprises, Fig. 1, a piezoelectric crystal wafer 10 sandwiched between metal electrodes 12 and 14. In order to isolate the crystal wafer from temperature changes associated with the pressure pulses being measured an acoustic transmission line 26 is attached to the electrode 12. A further transmission line 28 may be attached as shown to electrode 14 in order to prevent reflection of the pressure pulse at the electrode 14. The lines are preferably made of the same material as the crystal wafer in order to inhibit reflections at the junctions. In the preferred embodiment the wafer may be of tourmaline, barium titanate or quartz 0.7 cm. diameter and 0.02 cm. thick and the transmission lines 7 cm. long, 0.7 cm. dia. Connection to the -indicator, oscilloscope 16, is made via coaxial stub 18, and the wafer is screened by metal tube 30. Calibration method.-The gauge is calibrated by attaching a conductive disc 35 to the gauge and applying a pressure pulse to this disc by means of a pulsed magnetic field generated by placing the upper surface of the single turn coil 37 (Fig. 2) in abutting relation with disc 35 and then discharging capacitor 44, previously charged to a high-voltage from source 46, through the coil. The discharge circuit is critically damped by adding resistance to the circuit in the form of the strips 50 and 52 of resistance material, e.g. stainless steel. The amplitude of the pressure pulse applied to disc 35 is assessed by detaching disc 35 from the pressure gauge and placing the disc on top of the coil 37. The capacitor is then discharged through the coil and the height to which the disc is lifted by the pressure pulse, against gravity and air friction, is measured on scale 54. From this height the magnitude of the pressure pulse may be calculated as described in the Specification.

Abstract: 1432418 Discharging pipes from an endless conveyer MITSUI SHIPBUILDING & ENG CO Ltd 29 May 1973 [29 May 1972] 25422/73 Heading B8A A pipe 4 is discharged from an endless chain conveyer 2 by the action of a pushing and lifting member 27. The latter is deflected in a direction towards the conveyer 2 by the energization of a power cylinder 8 when the pipe is conveyed into a suitable position. The member 27 is connected to a member 10 carried by the outer end part 9 of the piston of cylinder 8. The member 10 also acts through springs 17, 17, on respective yokes 16, 16, pivotally connected to the member 27. The springs 17, 17, surround respective rods 13, 14, each slidable in guides on the cylinder 8 and rigid with a yoke 16. The leftward travel of the rods 13, 14, is limited by a stop formed by a pair of an adjustable threaded nut 18. In operation when the cylinder 8 is energized, the head 27 is pushed forward and lifted up. The latter action occurs because as the stops 18 engage respective abutments 7a, the rods 13, 14, are heated by the member 10 continues on its travel. The member 27 is thus lifted to the position shown in dot-dash lines in Fig. 2 due to the pivot axis 25 now being stationary. There may be a number of the transfer devices spaced along the conveyer and operated synchronously by the present device, by the action of a coupling rod 31.

Abstract: 589,622. Knitting - machines. MELLOR, BROMLEY, & CO., Ltd., and SHORTLAND, A. Dec. 19, 1944, No. 25444. [Class 74 (ii)] A mechanism for feeding yarn to the needles 1 of a circular machine comprises a yarn guide 3 and an associated trapper. The yarn, held between the guide and the trapper, is introduced to the needles by being extended from front to back of the sinkers so as to be engaged by a following sinker 2<1>. The guide is slidably mounted in a swivel 4 carried by a bracket 5 attached to the underside of the top plate 6 of the machine. The end of the guide is attached to a crank 8, rotated by a lever 26, which, when operated, imparts a reciprocatory motion to the guide. The trapper comprising movable fixed jaws 10, 9, is operated by a lever 29. A series of cams 18, 19, 20, rotated through a clutch by the action of a toothed rod 15 on a ratchet 14. actuates the levers operating the guide and trapper. The trapper is positioned above the sinkers and the guide is movable from front to back of the sinkers so that initially the guide is swung downwards extending the yarn, the end of which is held by the trapper, from front to back of the sinkers and in such a position as to be engaged by the following sinker 2<1>. As the yarn is further extended by the sinker and taken by the needles, the guide is swung upwards above the sinkers to continue feeding the yarn to the needles, and the trapper releases the yarn. Feeding of the yarn is discontinued by the guide being withdrawn and the yarn severed by the trapper and held in readiness for the next introduction. To ensure that the yarn is initially engaged and taken a sinker is adapted to project further than the others and the corresponding needle is prematurely lowered. The mechanism may be used in machines having bearded or latch needles and having rotary or stationary needle cylinders.

Abstract: 1399374 Treating combustion products; heat exchangers EMW-BETRIEB SCHAUMSTOFF KG EMMERLING & WEYL 31 May 1972 [2 June 1971] 25445/72 Headings FIB and F1L [Also in Division F4] A method for burning products of incomplete combustion comprises supplying the said products to a rotatable heat exchanger 7 with a heat exchanging part 13 consisting of a three dimensional arrangement of five elongate elements which in operation produces microturbulence, so that the products flow through a circumferential portion of the heat exchanging part 13, are then burnt and the burnt mixture flows through a further circumferential part 13 in such a way that at least part of the heat of combustion heats the products to be burnt. Air may be mixed with the products of incomplete combustion via port 14 as they enter the heat exchanger along channel 2 or air may be pre-heated by being passed through a different portion of the heat exchanging part before admixture with the products of incomplete combustion. Supply of these products causes rotation of the heat exchanger, which may also be rotated by a boosting drive from the engine. Combustion within the rotor 7 can be initiated by a sparking or glow plug or a catalyst. The heat exchanging part 13 may comprise threads or wires of a highly refractory metal element or alloy. The rotor may be integrally formed of the material of the heat exchanging part. The housing 1 of the device consists of thin highly refractory sheet metal which is thermally insulated externally. To improve heat transfer the products of incomplete combustion may be passed more than once through the heat exchanging part before being burnt, the burnt products also being passed several times through the heat exchanging part. To prolong reaction time before the burnt products pass through the heat exchanging part, the mixture  may pass through a retaining space (41) Fig. 4, (not shown) for example in the form of a spiral shaped passage or an additional chamber. The device also acts as a muffler to reduce exhaust noise.

IPC: D06C3/00
Filed: 1923-10-15
Abstract: 230,878. Durrant, G. Oct. 15, 1923. Registering webs. - Relates to apparatus for guiding a fabric web into a stentering or other machine, in which the selvages of the web are engaged by an upper positively driven roller and a lower roller which is moved into and out of gripping contact with the web by connections from a feeler engaging the selvage, and consists in improved constructions of the mechanism by which the roller is operated by the feeler. In one form, Fig. 2, the lower roller f is carried by a pivoted frame e resting upon a second frame m, which is mounted upon a pivot o and carries a roller m between which and a stationary roller l moves a wedge j pivoted to the upper end of a bracket h mounted on a pivot i. A doublearmed lever k, also pivoted on the bracket h, is spanned by a fork on one arm z of a two-armed lever, the other arm y of which forms the feeler engaging the selvage. If the selvage moves away from its correct path, the feeler correspondingly moves and tilts the lever k into a position to be engaged by one or the other of two projections s, s<1> on a constantly oscillating lever r. The bracket h is thereby turned on its pivot i and the wedge j forced between the rollers n, l or withdrawn therefrom, thus increasing or decreasing the pressure between the rollers f, d. In a second form, the projections s, s<1> are constituted by the upper ends of the pivoted arms linked together and oscillated by projections on a rotating disc. In a third form, Fig. 7, the wedge j is pivoted by a disc 28 having two notches 13, 14 adapted to be engaged by pawls 18, 19 on a member 15 constantly oscillated by a link 20. The feeler is connected by a link 25 to a pivoted member 22 carrying two pins 23, 24 adapted, when the feeler moves, to disconnect one pawl and allow engagement of the. other, so that the disc 28 is turned to actuate the wedge j. In a further form, similar to that last described, the wedge j is dispensed with and the edge of the disc 28 is provided with a recess forming a cam directly engaging the roller n, the disc being arranged beneath the bracket m.
