Title: Improvements in thread-tacking and like machines
IPC: D05B97/02
Filed: 1922-08-09
Abstract: 185,401. Venditti, G. Aug. 26, 1921, [Convention date]. Hand-sewing tools; marking work for sewing. -A free-loop stitching hand-sewing tool is moved by hand to follow a predetermined outline for the purpose of tacking together two pieces of material, so that by slightly separating the pieces, the threads between them may be cut, thus leaving identical patterns marked on each piece. A handler b integral with the frame a has pivoted thereto at b<1> two levers b<2>, b<4>. The sector c meshes with a toothed wheel c<2>, whieh is loose upon a fly-wheel shaft d and is integral with a ratchet c<3>. A spring-pressed pawl c<5>, pivoted to a plate c<4> which is fixed to the shaft d, engages the ratchet c<3>, A pawl e<1>, Fig. 1, pivoted to a disc e which is keyed to the shaft d engages a notch f' in a disc f. The disc f is loosely mounted on the shaft and actuates by means of a pin-and-slot connection the needlearm g, which is pivoted on a pin g<2>. A spring- pressed lever g<4>, Fig. 2, mounted on the pin g<2> tends to keep the needle out of the material.. The handles b, b<2> are operated to transmit a continuous rotary motion to the fly-wheel shaft d, thus reciprocating the needle h. The machine rests on milled wheels i on a shaft i<1> to which is also fixed a notched diso i<2>. A pawl j, which co-operates with the disc i<2>, is fixed to a pin j<2>, integral with levers j<3>, j<4>, Fig. 1. The pawl engages a notch i<3> on the disc i<2> during stitch forming to hold the tool stationary. As the needle leaves the material, a cam projection e<3> on the disc e forces downward the lever j<3> so as to disengage the pawl f from the disc i<2>, so that the machine can move forwards until the pawl j engages the next notch i<3>. When the lever j<3> is forced downwards, the lever j' is brought into the path of the tail of the pawl e<1> which is raised thereby from engagement with the disc f. Reciprocation of the needle is therefore stopped until the pawl j engages in the next notch i<3>. The needle h, Fig. 4, is grooved at p<1>, p<2> on either side of the eye p so as to reduce the friction between the needle and the thread.

Title: Improvements in or relating to oil tanker cargo pumping systems
Inventor: LAMB JOHN
IPC: F04D13/00
Filed: 1954-07-28
Abstract: <PICT:0793013/III/1> <PICT:0793013/III/2> An oil tanker cargo pumping system (see Group XVII) includes means for separating gases from the oil as it is being discharged by one or more centrifugal pumps.  A gas collector as shown in Fig. 3 has a port 1 for connection to the inlet side of a centrifugal pump and a port 5 for connection to a separate priming pump.  A valve 89 is normally closed by a spring 90, and a float 86 is normally in an upper position due to the surrounding oil.  As gases are collected, the float 86 descends until it operates a servo device 88 causing the valve 89 to open and so allow the accumulated gases to be extracted by the priming pump.  As the gas is extracted the gas collector fills with liquid and the float 86 rises to a position where it causes the servomotor 88 to close the valve 89.  Liquid trapping apparatus.  Between the priming pump and each gas collector, Fig. 3, is a liquid trapping apparatus, Fig. 2.  This has a port 18 coupled to the priming pump, a double valve 67 arranged to provide communication with the atmosphere when open, a non-return valve 61 coupled to the gas collectors and a port 16 coupled through a one-way valve to the inlet side of the centrifugal discharge pumps.  As gases are drawn in through the valve 61 by the priming pump coupled to the port 18, any entrapped liquid settles in the receiver 60 and raises the float 62.  The vacuum holds the oneway valve shut.  As the float 62 rises, it acts on a spring-biased arm 66 which eventually snaps over to cause a sudden opening of the double valve 67, this breaks the vacuum in the receiver 60 and the accumulated liquid in the receiver flows down the conduit 16 past the one-way valve and back to the inlet sides of the centrifugal discharge pumps.  The float 62 then descends until the double valve 67 is caused to close, whereupon the vacuum is re-established.  Should the liquid level accidentally rise to the height of a ball valve 78, the ball valve 78 closes the port 18. Modified liquid trapping apparatus.  The receiver may be replaced by a vertically movable cylinder balanced by a counterweight and coupled to the various pumps by flexible tubes.  As liquid collects in the receiver it descends until, through a lost motion mechanism, it suddenly causes its internal vacuum to be broken to permit the accumulated liquid to pass back to the gas collectors. When this has been done, the now lighter receiver rises and through the lost motion mechanism suddenly causes the vacuum created by the priming pump to be re-established.

Abstract: 1,204,237. Testing fabrics. CLUETT, PEABODY & CO. Inc. 9 May, 1968 [27 July, 1967], No. 22040/68. Heading D1S. [Also in Division G1] The abrasion resistance of a sheet material, e.g. a fabric, is tested by continuously directing high-velocity abradant particles against one surface of the material and measuring the time required for the abradant particles to 'break through the material. As shown in Figs. 1 and 2, a nozzle assembly 201 and a specimen mounting assembly 202 are mounted in an enclosure 100 exhausted through a pipe 111 containing a fan 112. The assembly 201 comprises a nozzle 203 connected through a line 103 to a compressed air or gas source 110 via an air cleaner 107, a filter 108 and a pressure regulator 109. The nozzle 204 is connected through a line 104 to a source of abradant grit which is drawn, by the pressure of air through the nozzle 203, into a main nozzle 205, preferably of hardened steel or boron carbide. A fabric specimen 212 is held between clamps 210, 211 with a soft rubber gasket 213 located therebetween and the nozzle 205 directs the abradant thereagainst. The clamp 211 is made of transparent material to allow observation and has a chamber 214 connected to a manometer 120 through a velocity pressure tap 215 and a static pressure tap 216. When breakthrough of the fabric occurs, the impingement of air from the nozzle 205 on the tap 215 causes an abrupt change in the manometer reading. A piezoelectric element (not shown) may be attached to the clamp 211 to sense the change of noise level therein due to breakthrough and is connected to a stop-clock or a graphical device. After striking the specimen 212, the abradant grit falls through a metal grill 113 into a trough 114 shaken by a motor 118 so that smaller broken particles pass through an inclined wire mesh screen 117 and the unbroken particles fall into a funnel 115 and are fed by an aspirator 119 to a reservoir 105 to be recirculated. The abradant grit 106, preferably silicon carbide, is fed into the line 104 from the reservoir 105 through a tee fitting 300 having an air bleed 302.
