Title: Tubing catcher for use in wells
IPC: E21B23/01
Filed: 1935-01-18
Abstract: 447,149. Catching and anchoring tubes in wells. BYRON JACKSON CO., 2150, East Slauson Avenue, Los Angeles, U.S.A. Jan. 18, 1935, No. 1770. Convention date, Jan. 29, 1934. [Class 85] A tubing catcher for use in wells comprises a member connected in the string of tubing and provided with one or more upwardly and outwardly inclined seats, a slip slidable on each seat, spring means urging each slip outwardly away from its seat, and means for holding each slip slidably against its seat. A head 4, integral with or welded &c. to a nipple 1 arranged in the tubing, has inwardly and downwardly tapered seats 5 as described in Specification 389,114; each seat receives a serrated slip 7 with a lower inclined surface 9 seating against a complementary surface 10 in the head 4, the upper end of each slip having a finger 11 with lugs 12 engaging a recess in a slidable actuator 15 to retain the slip in position. A bow spring 13 is arranged in a groove in the rear face of each slip and is bent at its upper end to engage a slot 18 in the actuator, the springs also each bearing against an abutment 21a in the actuator so that the lower end of the spring tends to force the slip outwardly. The weight of the slips and actuator normally holds the slips against such outward movement, but after a break, relief of pressure on the seats 10 permits the springs to force the slips against the casing. An anchor as described in Specification 389,114 may be provided below the device to permit manual control of the slips for anchoring the tubing. In another form, the actuator and springs are arranged below the head, the upper ends of the slips being restrained from outward movement by engaging dovetail grooves or by an outwardly inclined finger engaging behind an abutment on the head 4. The slips and actuator may be connected by reins pressed outwardly by coil springs to actuate the slips. If a single slip is used, the actuator is omitted. Specification 289,228, [Class 102 (i)], also is referred to.

Title: Improvement in loom stopping mechanism
IPC: D03D51/00
Filed: 1935-12-04
Abstract: 466,844. Loom stop-motions. CROMPTON & KNOWLES LOOM WORKS. Dec. 4, 1935, No. 2078/37. Convention date, March 6, 1935. Divided out of 466,787. [Classes 142 (i) and 142 (iii)] In a loom having a weft detector co-operating with the shuttle, and a warp stop motion, loom stoppage occurs with the depleted shuttle at one side when the stoppage is caused by the weft detector mechanism, but with the active shuttle at the other side when the stoppage is caused by the warp stop motion. During the beats of the loom when the weft detector acts, initiation of loom stoppage by the warp stop motion is prevented. The loom may have a multi-shuttle magazine as described in Specification 466,787, a double pronged electric feeler 66, 67 on a spring-controlled lever 60 entering the active shuttle when this is in the upper shuttle box 35 at the magazine side of the loom. On occurrence of weft depletion, a circuit is completed through contacts 155, 158 and a switch 111, a solenoid 100 being energized whereby later, when the shuttle has returned to the opposite (drop box) side, the loom is stopped. The solenoid is also included in the circuit of the warp detector mechanism, but this circuit is interrupted at contacts 162, 163 at the beats when the weft detector is operative, being closed, however, at alternate beats by a contact 164 on a cam-actuated lever. The core 101 of the energized solenoid raises a link 102 on a lever 93, the link being held in its raised position by a weighted lever until, later, it is operated by a rocking lever 96, whereby the lever 93 is rocked and, by means of lever mechanism 92, stops the loom. The lever 96 is operated by two cams 97, 175. One is adjustable and causes loom stoppage to occur when the active shuttle is at the magazine side whilst the other causes the stoppage to occur when the active shuttle is at the drop box side of the loom. A spring-controlled lever 105 is connected by a rod 106 and an adjustable clip 108 and spring 109 to the stem of the switch 111, which is thereby closed when the shipper handle is in the driving position, but is otherwise open.

Title: Leakage test method
IPC: G01M3/22
Filed: 1975-01-20
Abstract: 1488954 Leak detecting  MASCHINENFABRIK AUGSBURG-NURNBERG AG 20 Jan 1975 [24 Jan 1974] 2298/75 Heading G1S A leak in a hollow body is detected by introducing the body into a leak proof test chamber, removing air from the space within the hollow body and the space within the test chamber, introducing tracer gas into one of the said spaces, removing any gas passed to the space not fed with tracer gas and comparing the amount of gas removed with the amount of tracer gas absorbed through a calibrated leak, the tracer gas from the other space being removed and collected. Hollow bodies 1 and 31 to be leak tested are placed under bell jars 4, 34 and evacuated to about 0À5 Torr together with the jars by a pump 6 by way of valves 7, 8; 37, 38. At this reduced pressure valves 7, 37 automatically close, but the bell jars are  further evacuated. A valve 9 opens as soon as valves 7 and 37 close and the bodies 1, 31 are further reduced in pressure by way of valves 13, 43 and pump 15, a cooling trap of liquid nitrogen 14 absorbing oil and water vapours which might damage the control circuit. At the same time the trap 14 produces a pressure gradient to the leakage finder 16, and pressure measuring points P control a previously programmed control device which largely automatically controls and monitors the testing apparatus. A progressively opening valve 17 leading to the leakage finder 16 receives its opening impulse from a pressure switch 18 but receives its command for remaining at a particular degree of openness from the pressure measuring device in the leakage finder itself. Quantitive measurement of the leakage rate is possible if 17 is inhibited at a certain degree of opening by passing only a predetermined portion of the gas flow to the detector. A tracer gas (helium) is then passed into the bell jars from a storage container 21 via valves 19, 12, and 42 until a predetermined pressure is reached. The time for the pressure to rise and hold for measurement must be determined by preliminary tests but any tracer gas passing through into the hollow bodies is detected by 16 which gives a leakage rate which is compared with the leakage rate through a calibrated leak 29 which has previously been evacuated by a pump 26 and valve 27. After the test, or if an excessive leakage rate is already indicated during inflow of the tracer, valve 19 closes and valve 20 opens to compress the tracer gas back into 21 via pump 23 and filters 24. Following this, air is admitted into the jars through valves 11 and 41 and an inert oxidation preventing gas such as nitrogen is then admitted into the hollow bodies which are still sealed by closure devices 25, 55. The inert gas may be introduced into that space not fed with tracer gas to enable a desired safe pressure gradient to be obtained between the interiors of the hollow bodies and the interiors of the bell jars.
