Title: Automatic Gain Control Circuit.
Inventor: HANSEN ROBERT BRUCE
IPC: H03G3/30
Filed: 1968-08-06
Abstract: 1,188,752. Automatic gain control. MOTOROLA Inc. 6 Aug., 1968 [28 Sept., 1967], No. 37519/68. Heading H3T. In a signal receiver the A.G.C. controlled current in one stage is used to control the gain of a later stage in reverse sense aboveapredetermined signal level, so that the gain of the later stage then remains constant. As applied to a television receiver an A.G.C. circuit of the gated type derives a delayed control potential from sync. signals in circuit 50 which is applied over line 52 to the base of I.F. amplifier 58, via resistor 54; the arrangement is such that gain is reduced by increasing the collector current. The change in potential across emitter circuit resistor 60 so caused is applied via resistor 64 to the base of preceding I.F. amplifier 68 so that its gain is likewise reduced. The gain control potential on line 52 is also applied over a further delay circuit 74 and resistor 76 to reduce the gain of R.F. amplifier 80 by increase of collector current. The gain is initially reduced in the I.F. stages; when the gain in the R.F. stage 80 begins to be reduced the increase in voltage drop across resistor 82 in the collector circuit is applied over resistor 100 to the base of the I.F. stage 58. The gain control potential derived from line 52 is thereby opposed, so that the current in transistor 58 remains constant, thereby maintaining the gain of this stage and of transistor 68 constant. When the R.F. stage 80 becomes biased back, no further change in the potential derived via resistor 100 occurs, and the gain of the I.F. stages reduces once again.

Title: Vent window system for vehicle body structure

Filed: 1971-08-12
Abstract: 1316521 Window operating mechanism FORD MOTOR CO Ltd 12 Aug 1971 [25 Sept 1970] 37885/71 'Heading E2M A window operating mechanism, for a vehicle window divided into two sections, comprises a pair of drive arms coupled to the window sections, drive means coupled to the drive arms to operate the latter sequentially to first lower a first section independantly of the second section and then to lower the two sections together, and a latch mechanism holding the drive arm coupled to the second section against movement until released by the drive arm coupled to the first section upon the latter being lowered a predetermined distance. In operation, a gear sector 22 is driven clockwise, by an electric motor and reduction gear unit 24, which results in link 31 being driven upwards. As the link is coupled via pin 33 to end 28 of the first drive arm 26, a clockwise swinging motion is imparted to this arm causing pivot 34 carried on the end 29 to be swung in the direction of the arrow 72. The support arm 35 is carried down around the pivot shaft 25 axis and forces the pivot stud 42 on control link 43 to follow a circular path as indicated by line 73, resulting in roller 37, accommodated in channel 38 on a bracket [39] attached to the ventilation (first) section, following a vertical downward path. A last motion device comprising a pin 33 in a slot 46, and a latch mechanism 59, prevent any movement of the second drive arm 27 until the first window section is open. When the pin 33 reaches the top of slot 46 and also the complementary slot 63 in the latch plate 61, the pin 33 becomes aligned with a lateral offset 64, and a spring 65 operates to pivot the latch 59 about a pivot stud 62, until the lower edge 69b of a indentation 69 is moved out of the path of a catch 71, thereby releasing second drive arm 27 for swinging movement, in a clockwise direction. This results in a downward movement of roller 48, causing downward movement of the second (visibility) section of the window panel. The gear sector 22 may be operated by a hand crank lever.

Title: Process for the manufacture of trimethyl phosphites
Inventor: COATES HAROLD
IPC: C07F9/142
Filed: 1958-11-26
Abstract: Trimethyl phosphite is prepared by transesterifying a triaryl phosphite with at least a 70% excess over the stoichiometric amount of methanol at a temperature low enough to avoid substantially any concurrent isomerisation reaction and below the boiling point in the reaction conditions of the triaryl phosphite and the phenol produced, and removing the formed trimethyl phosphite by distillation with methanol from the reaction mixture. The reaction temperature may be between 0 and 100 DEG C.  The transesterification may take place partly during the distillation and some or all of the excess of methanol may be introduced countercurrent to the feed in this distillation stage which may be effected in a film still.  An esterification catalyst may be used, e.g. an alkali metal alkoxide or phenoxide.  The trimethyl phosphite may be separated from the methanol by distillation.  It is advantageous to maintain alkaline conditions during the distillations.  The Provisional Specification covers also the use of alkanols other than methanol in the transesterification.  Reference has been directed by the Comptroller to Specification 873,495.

In well apparatus comprising tubing 11 and a production piping 55 (Fig. 8) within the tubing and supporting a valve assembly 10 which includes a housing 14, slips 21 movable on the housing to engage a tapered surface 18, packer means 25, 26 adapted to close off fluid flow in the annulus A surrounding the housing, a port 27 leading to a cylinder 32 in the housing, a piston 31 working in the cylinder and integral with a spring biased tubular member 30, a second tubular member 45 biased by a spring 51 to engage a seat 48 on the housing to prevent well fluid passing through openings 46, and an opening 36 in the housing which may be aligned with opening 37 in the member 30 to equalize the pressures on the inside and the outside of the housing below the packers, a pump 73 (Fig. 8) applies fluid pressure to the annulus above the packers to move the members 30, 45 downwardly so that well fluid may flow through the openings 46, the interiors of the members and the piping 55 to the well head 60. The assembly is lowered to the desired location in the tubing 11 by means of a running-in tool 12 housing a stinger 52 which holds the member 45 in the position shown in Fig. 3 so that well fluid may flow through the openings 46, and members 45, 30 into the tubing above the packers. When at the desired location the tool is jerked upwardly to engage the slips with the tubing. Arms 17 of the tool are released from the assembly and the tool and stinger are removed the member 45 moving to the position shown in Fig. 6 to prevent flow of well fluid. The pipe 55 is connected to the assembly by latch arms (not shown), and the well is completed. A valve 72 (Fig. 8) is set to connect the pump 73 to the annulus so that piston 31 and the member 30 move until the openings 36, 37 are aligned to equalize the pressures inside and outside the housing. Additional pressure applied to the annulus causes the member 30 to move the member 45 to the position shown in Fig. 7 so that production fluid may flow upwardly through the assembly, piping, and well head to discharge through the line 69. The valve 72 is then set to connect the annulus to a diaphragm valve 76 controlling flow to a reservoir 79. A drop to a predetermined pressure in the line 69 actuates the valve 76 to release pressure from the annulus so that the members return to the positions shown in Fig. 6 and the flow through the line 69 is cut-off. The bleeding of the annulus may be resultant upon increase in well pressure, or on other conditions.
