Title: Method of and apparatus for supervising the running of automatic thread winding machines
IPC: B65H54/22
Filed: 1951-03-29
Abstract: 740,686. Winding machine control means. REINERS, W. March 29, 1951 [May 23, 1950], No. 7314/51. Addition to 740,685. Classes 120 (2) and 120 (3). The method of supervising the running of winding machines described in the parent Specification is modified in that should the number of tying failures reach a predetermined value, the winding operation is arrested by the disconnection of the drive to the winding-on spoool and/or of one or more automatic operations such as the operation of the automatic tying means or the automatic supply bobbinexchanging mechanism. As shown, an electromagnet 103 is introduced into the circuit of the instrument 47 which records the tying failures such that should a predetermined number of such failures occur and the pointer of the instrument 47 engage the contact thereof, the electromagnet 103 is actuated and lifts the spool frame 4 so as to remove the spool 3 from the driving drum 2. At the same time the electromagnet slides the contact 106 off the contact bar 107 so as to break the circuit containing the electromagnet 26, the armature 31 of which forms the latch which engages the notched disc 33 secured to shaft 36 as described in the parent Specification, so as to lock the said shaft against rotation, thus preventing operation of the thread tying and the bobbin changing mechanism.

Title: Method and apparatus for testing oil wells
IPC: E21B33/12
Filed: 1974-02-18
Abstract: 1463374 Wells &c HALLIBURTON CO 18 Feb 1974 [26 Feb 1973] 7373/74 Heading E1F A fluid sampler for use in an oil well test string, has a member which is reciprocated by varying the pressure of fluid in the annulus about the string. The sampler which comprises power and sampling sections releasably connected is located in the string adjacent a packer. In use the string is supported by a sub aqueous wellhead and extends through a riser to a vessel, the power section being above the sampling section and the packer being below the sampling section. The power section is charged with low pressure nitrogen which together with a spring acts downwardly on a piston fixed to the member. As the string is lowered into the well the effect of buoyancy is counter balanced by annulus fluid acting downwardly on a further piston, the annulus fluid also passing through ports to act on the nitrogen to increase its pressure with depth. When the packer is just above the formation to be sampled the packer is set and the weight of the upper part of the string is allowed to telescope parts of the power section closing the ports. The piston which is biassed by the spring and nitrogen is also subjected to the pressure of the annulus fluid acting upwardly so that increase in annulus pressure moves the piston and member upwardly. The lower part of the casing of the power section is fixed to the casing of the sampling section and the member is attached to a pull mandrel of the sampling section. Increased annulus pressure moves the member together with the mandrel upwardly to open ports in the sample chamber of the sampling section to permit formation fluid to flow upwardly through the chamber and string. Release of the increased pressure moves the member and mandrel downwardly to trap a sample of formation fluid in the chamber. When the sample section is removed from the string formation fluid trapped in the sample section but not in the chamber is discharged through a spool valve, and parts of the casing are removed to give access to valves draining the sample from the chamber. Should the well be threatened with a blow out through the annulus the increased pressure moves the member with such force that a close and lock device in the sampling section is actuated.

Abstract: 346,543. Clocks. WHIDBOURNE, H., Royal Aircraft Establishment, South Farnborough, Hampshire. March 12, 1930, No. 8054. [Class 139.] Escapements ; transmitters. - A pendulum e s - capement mechanism comprises a pivoted gravity arm (impulse member) 25 for acting intermittently on a pin 24 on the pendulum 21, a second pivoted arm 30 movable with arm 25 to lock and unlock the driving mechanism alternately, and a third pivoted arm 33, acted upon by the driving mechanism for moving the second arm 30 in and out of locking position. The pivoted pin 24 is in a recess 23. in the pendulum which is supported on the usual strip 22. A weight is used for driving scape member 28 which has limbs 29 and lateral pins 31. The first and third arms 25, 33 are rigid with shaft 26 and second arm 30 is loose on this shaft but is. biased counterclockwise, Fig. 5, by a spring, a projection 39 on this arm meeting a stop on the back of arm 33. A block 44 on arm 25 carries a blade 43 with a contact 41 which coacts with a fixed contact 42. Pivoted to the end of third arm 33 is link 32 having a collar 34 which coacts with pins 31. A lug 37 on arm 33 limits the movement of link 32 in one direction and a fixed pin 38 in the other direction. With the pendulum central, 27 rests on pin 24, contacts 41, 42 are closed, and second arm 30 holds a limb 29. As the pendulum swings to one side the three arms 25, 30, 33 fall and the part 27 gives the pendulum an impulse through roller 24, lever 30 releases the limb 29 and'the scape member 28 rotates, until a pin 31 raises link 32 and arm 33. This raises arm 30 to engage the next limb 29. Arm 25 is not raised sufficiently to close contacts 41, 42, however, until on the return movement of the pendulum the roller 24 lifts the arm 25 to its highest position to close contacts 41, 42. This action of roller 24 also raises arm 33 and link 32, so that the latter is moved off its pin 31, and the three arms 25, 30, 33 drop to release the scape member once more. Roller 24 and part 27 may be interchanged: The impulses given when contacts 41, 42 close may, for example, be used for controlling speed-regulating devices, such as described in Specification 334,214, [Class 57, Governors & c.], or for. controlling secondary clocks. A lost-motion device between the first and second .arms is described, in a modification, to ensure that the first arm,. 25, completes its impulse-giving movement before the second arm releases the scape member. Specification 233,828, [Class 139, Watches &c.], also is referred to.

A method of manufacturing pleated products is characterized in that the material is drawn through or over a plurality of creasing devices arranged in convergent relationship and in succession so that the first creasing devices cause the material to assume an open zig-zag formation and the succeeding creasing devices cause the partially pleated material to acquire progressively a closer pleated formation as the fabric travels to the place of delivery, and in that after pleating by the creasing devices aforesaid the pleated material is subjected to compression laterally to enhance the sharpness of the pleating. As shown in Fig. 2, the apparatus comprises a sector-shaped table 20 with a rearward extension 202 and comb device A, B, C, D through which fabric F is drawn from a roller 21 and which are mounted on the table. The first three comb devices are arcuate. Each comb device comprises superposed upper and lower portions having interengaging V-shaped grooves, those of the first device A being open and shallow whilst those of the devices B and C are deeper and closer. The comb device D consists of closely spaced deep vertical interlacing teeth giving a pleated formation of the required depth to the fabric which then passes through a compressor E closed by means of a winch 26. In an alternative construction, Figs. 1 1 and 13, a plurality of slots 31 with upstanding ribs 32 of progressively increasing height are pivoted to the upper surface of the table, removable guide blocks 35 pressing the fabric on to the ribs. An arcuate member 33 has pivoted thereto the inner ends of a plurality of convergent members 34 fitting in between the ribs 32 and leading to the compressing device E.
