Title: Wall packer assembly
IPC: E21B33/1295
Filed: 1964-12-09
Abstract: 1,021,610. Wells &c. CAMCO Inc. Dec. 9, 1964 [Jan. 2, 1964], No. 50173/64. Heading E1F. A well packer comprises a packing collar 21 sleeved on a packer mandrel 12 between upper and lower slips 28, 14, a tubing mandrel 2 on which the mandrel 12 is slidably sleeved, a passage 25 for applying fluid pressure to project a latch 40 on the mandrel 2 into a keeper formation 33 on the mandrel 12, and mating surfaces 31, 31A on the mandrels for closing the passage to apply the fluid pressure at a limit of relative sliding of the mandrels. The packer is lowered into the well on a tubing string 3 and is set by elevating and rotating the string to bring pins 20 carried by the mandrel 12 into alignment with the vertical leg of J-slots 8 in the mandrel 2, and by lowering the tubing string. The mandrel 12 is held fixed in the well by friction blocks 15 and the string is lowered until mandrel surfaces 38, 32 engage and set the slips 14 and expand the collar, the surfaces 31, 31A also being engaged to cause fluid pressure from the annulus beneath the expanded collar to project the latch and set the slips 28. The packer is released by upward pull on the tubing string with or without reduction of the annulus pressure, the mandrel 12 being lifted by the flared mouths of the vertical limits of the J-slots engaging teeth on a ring 10.

Title: Hardening of chromised steel
IPC: C21D1/20
Filed: 1973-10-31
Abstract: 1436565 Heat-treatment of chromized steel CHROME ALLOYING CO Ltd 15 Oct 1974 [31 Oct 1973] 50608/73 Heading C7A The tensile properties of a stabilized and chromized steel containing Fe Bal, and impurities, with up to 1À5% each of Si and Mn and optionally 0À5-1À5% Ni are significantly improved by heat-treating at 400-550 C for times of 12 hours to 30 minutes, depending on the temperature. The chromized steel must be in the solution treated condition, and a solution treatment in the range 800-1050 C is used subsequent to chromizing, which may be by pack diffusion, prior to the ageing treatment. The resultant material is suitable for fasteners i.e. nuts, bolts, &c. and the heat-treatment may be carried out either on stock or finished material.

Title: Preservation of a stored voltage
IPC: G05B9/02
Filed: 1971-10-19
Abstract: 1373755 Automatic control systems KENT INSTRUMENTS Ltd 19 Oct 1971 [26 Oct 1970] 50849/70 Heading G3R In an electric controller having an integrating capacitor 11 connected across an amplifier 12, means are provided for isolating one side of the capacitor in the event of supply failure so that it retains its charge. The capacitor 11 may form part of the controller described in Specification 1224167. When the supply at 25 drops below a prescribed value, determined by Zener diode 29, transistors 24, 22 cease to conduct and capacitor 11 is thereby isolated. Capacitor 21 provides a low impedance path to switching transients. When full voltage is restored the transistors turn on only after a further capacitor 30 is charged; this delay, whose duration depends upon the amount 30 discharged during the "off" condition, allows the controller to resume normal operation before 11 is reconnected.

Abstract: 1444579 Terminal MOLEX Inc 6 Nov 1973 [29 Nov 1972] 51511/73 Heading H2E To connect an insulated wire to a blade-like male contact (not shown) a planar sheet-metal terminal 20 carries plate portion 28, rimstiffened at 30, with stamped-out apertures 48, 50, 52 defining resilient arms 54, 56 carrying integral smooth opposing contact-segments 58, 60 turned up over part of their length and fitting with interference on the appropriate male contact. Rim 30 continues 68 to stiffen coplanar tag 22 which is crimped 36, 38 to the conductor and also at 42, 44 to the insulation of a cable. Tang 66 retains the terminal in an insulating holder if one is provided. Alternative designs include lateral instead of longitudinal arms (Figs. 6, 7, not shown), arms widely spaced to mate with a square contact (Figs. 10, 11, not shown), and for a round pin a circular terminal (Figs. 8, 9, not shown) with three circumferential sectional slots defining inner circumferential arms carrying inward facing contact segments round a central hole. In all designs the arms bend and twist slightly on contact entry to maintain pressure. A schematic composite insulating connector housing carrying all four quoted designs of terminal to fit appropriate male contacts is illustrated (Fig. 12, not shown) with a cavity to house each terminal and a passage onto each cavity for lateral insertion of the terminal. A second orthogonal lateral passage may be provided for alternative orientation of any terminal, with change from Fig. 1 design to (Fig. 6) if a blade-like male contact is to be connected. Shoulders are provided in the cavity for engagement with tang 66 in all permitted orientations. A passage enters each cavity to allow access by the male contact. In a further design of connector (Figs. 14, 15, not shown) two terminals of Fig. 1 type are used to connect male blade contacts to conductors of a tape cable; an opening from the face of each cavity remote from the blade entry allows further connection after engagement of the terminal.

Abstract: 1326268 Time delayed transistor switching circuits TOYOTA CHUO KENKYUSHO KK and TOYODA JIDOSHOKKI SEISAKUSHO KK 6 Nov 1970 [7 Nov 1969] 53005/70 Heading H3T [Also in Divisions D1 and F1] In an hydraulic or compressed air operated linear piston cylinder motor 4, 5 for moving an  inertia load, e.g. the ring rail 23 of a textile  spinning machine and wherein opposite ends of the cylinder are connected by lines 6a, 6b and a two-position reversing valve 7 to a supply 10 and a return 13, damping of unwanted oscillatory deviations of the motion of rail 23 at reversal, i.e. when valve 7 is moved from the first position shown to its second position and vice versa is effected by returning the valve 7 to its first position after a predetermined time interval, e.g. 0À04 sec. maintaining the valve in said first position for a period insufficient for the piston 5 to undergo movement, e.g. 0À02 sec. after which the valve 7 is then returned to its second position. Horizontal piston movement is transmitted to the ring rail 23 via a rod 20 and drive bars 21 whereby the rail is reciprocated in a vertical plane and closes switches 19a, 19b which energize solenoids 8a, 8b by which the valve 7 is reversed. The switches and solenoids are in an electrical circuit provided with control means 30 whereby the solenoids are timed. In operation and on closing of switch 19a, transistors Tr 5 , Tr 6  turn-on. Solenoid 8a is thus energized and valve 7 is moved to the left into its second position. When after 0À04 sec. the condenser C 1  is charged Tr 1  and Tr 2  turn on and Tr 3  turns off. Tr 4  and Tr<SP>1</SP> 6  thus turn on and Tr 5  and Tr 6  turn off: solenoid 8a is thus deenergized whilst 8b is energized thereby switching valve 7 to its first position shown. In a succeeding second time interval (e.g. 0À02 sec.) charging of a condenser C 3  connected to the base of Tr 3  occurs and at the end of a 0À02 sec. charging interval reversal of an emitter coupled monostable multivibrator Tr 2 -Tr 3  causes Tr 5 , Tr 6  to turn on again thereby energizing solenoid 8a and returning valve 7 to its second position. A limit switch 19b is subsequently operated and the lower part of the circuit operates in a similar sequence to produce of reverse movement of the valve.

In a fluxgate magnetometer comprising a ferromagnetic core 1, a drive winding 4 and a sense winding 2, the drive winding is energized with square-wave pulses of direct current and the arrangement is such that variations in the driving flux produce no resultant output voltage in the sense winding which responds only to the varying degree of core saturation which is dependent on the flux in the core due to the magnetic field h being measured. As shown in Fig. 1, the drive winding is in two series-connected parts 4a, 4b wound on respective limbs of a two limb core, in which connection 1c may be omitted. A feedback winding 7 connected to a control and measuring device 8 enables the field being measured to be nulled, the feedback current to do this being measured to indicate the field strength. In an alternative arrangement, Fig. 2 (not shown), a single drive winding (14) is wound on a circular core (10) and two series-connected sense windings (12a, 12b) are provided. In another arrangement, Fig. 3 (not shown), a toroidal drive winding (24) is wound on a cylindrical annular core (20) and the sense winding is arranged with its axis at right angles to the flux generated by the drive winding.
