Filed: 1962-12-13
Abstract: 1,016,284. Secret transmissions. WESTERN ELECTRIC CO. Inc. Dec. 13, 1962 [Dec. 18, 1961], No. 47063/62. Heading H4R. A message signal is rendered secret by marking it with a number of spaced echoes of the signal itself. Preferably, reverse reverberation is employed, e.g. a number of spaced echoes of increasing amplitude preceding the signal. The reverse reverberation may be obtained by the circuit of Fig. 3 comprising a delay line 31 having a series of taps 32 ... 35 which are taken through amplifiers 37 . . . 40 having progressively increasing gain, the outputs being combined in an adder network 42 with the signal itself fed through a negative gain amplifier 41. The contributions of the several amplifiers are indicated in Fig. 2 (not shown). A number of such circuits may be employed in series, each having different parameters, and if desired, normal reverberation may be added. A somewhat similar circuit may be employed at the receiver for cancelling the reverse reverberation, or use may be made of the normal reverberator having a feedback loop described in Specification 1,001,518, Fig. 5 (not shown). In practice the delay line may be realized by a rotating magnetic drum having a single recording head and a number of spaced pick-up heads, Figs. 8, 10, 12 (not shown).

Title: Constant electrical power regulator
IPC: H02M3/28
Filed: 1966-10-21
Abstract: 1,144,480. Power and voltage regulation. UNITED STATES ATOMIC ENERGY COMMISSION. Oct.21, 1966 [Nov.30, 1965], No.47428/66. Headings G3R and G3X. A radio-isotope fuelled thermo-electric generator is provided with a regulator which maintains a constant power output from the generator throughout its useful life. As shown, such a generator 10 supplies a load 16 partly directly by way of a line 12 and the centre-tapped secondary winding 46 of a saturable transformer 40 and partly by way of a conventional blocking oscillator 32 which functions as a voltage booster and which includes the transformer 40, transistors 34, 36 and a biasing resistor 30 the potential across which determines the magnitude of the oscillator output voltage, this potential itself being a function of the conductivity of a transistor 26 associated with the resistor 30. A Hall effect device 18 is connected to detect the power output of the generator 10, the signal from this device being applied to the base of transistor 26 by way of an operational amplifier 22. In operation, with the initial generator current at a relatively high value the generator voltage is relatively low Fig. 1 (not shown); the output signal from device 18 is at a maximum level, the transistor 26 is heavily conductive, a substantial portion of the generator current is drawn through the oscillator 32, and the oscillator produces a lower current, higher voltage signal which, when added to the direct generator output coupled to centre tap 52, provides the desired voltage drop across the load 16, this desired voltage corresponding to the unboosted voltage of the generator at the end of its useful life, which latter voltage is higher than the initial generator operating voltage Fig. 1 (not shown). Variations in the signal from device 18 cause corresponding variations in the oscillator circuit path whereby the net circuit impedance is automatically correctively varied in a sense such that the output power is maintained constant. As the radio-isotope fuel decays, the current from the generator falls but the voltage rises since the power is maintained constant Fig. 1 (not shown). Under these conditions, the arrangement is such that the voltage boost gradually diminishes, so at the end of the useful life of the generator the load 16 receives the unboosted voltage of the generator. The system thus maintains the power output at a constant value, whilst providing a constant voltage across the load 16.

Title: Improvements in or relating to fluidic frequency sensors
Inventor: DAVIS JOHN CHRISTOPHER HAMMOND
IPC: G01P3/26
Filed: 1967-10-18
Abstract: 1,211,548. Comparing frequencies. PLESSEY TELECOMMUNICATIONS RESEARCH Ltd. Jan. 14, 1969 [Oct. 18, 1967], No.47487/67. Heading G1K. Two frequencies are compared by producing a jet of fluid rotating about an axis in phase with one end and, in response to the other, causing the jet to be directed into a collector on successive occasions to produce a series of output pulses the repetition frequency of which is dependant on the relation between the two frequencies. Two discs 10, 12, Fig. 1, are arranged to rotate about a common axis at rates of revolution corresponding respectively to the frequencies to be compared, which may be the rates of revolution of two bodies or the frequencies of two pressure signals. A steady stream of fluid is applied to duct 14 and once in each rotation of one disc relative to the other, when the outlet 18 is aligned with the inlet 20, a fluid pressure pulse appears in the duct 16. A pure fluid device 22, Fig.2, comprises two momentum-interaction proportional devices 24, 30 with a common supply pressure and symmetrically arranged outlet ports 26, 28; 32, (34) forming jets inter-secting on the axis of symmetry about which a disc 48 rotates with its inlet 50 at an angle to the axis such that, during rotation it sweeps the surface of a cone having the same apex and angle as the rotating jet which results from supplying two sinusoidal signals to the ports 40, 42; 44, 46, 90 degrees out of phase, a pressure signal being produced in duct 52 when the rotating jet impinges on the port 50. In an embodiment, Fig. 4 (not shown) each of the frequencies to be compared is represented by the respective frequency of rotation of jets produced by two confronting pure fluid devices similar to device 22 which when in phase form a combined jet directed to a stationary annular collector to produce a fluid pressure signal. When not in phase the jet of each device is directed towards an annular vent in the other device. In another embodiment, Figs. 5, 6 (not shown) a similar arrangement with two sets of circumferentially spaced ports has each port of one set confronting a port of the other set and if each set is used to produce a rotating jet and the two are exactly in anti-phase, they will oppose each other and if they are of equal strength, no resultant is produced. An additional supply port directs a steady jet along the axis between the two sets of ports and a collector disposed on the axis receives the jet if it is not deflected producing an output signal at a frequency equal to the difference between those of the two rotating jets. Three or more devices are needed to determine which is the larger frequency.

Abstract: 1288207 Change-speed control NISSAN MOTOR CO Ltd 6 Oct 1970 [13 Oct 1969] 47490/70 Heading F2D Line pressure 56, for actuating friction clutches and brakes in an automatic transmission on a motor-vehicle, is controlled by a pressureregulator valve 51, subject to negative loading provided by back-pressure produced in a chamber 86 by spring-closing a nozzle 54 by deenergizing a solenoid 87, under control of a transistor circuit, 20 responding to voltage signals Vc, Vt, representing respectively vehicle speed and engine torque, so that line pressure is cut back with increase in speed and/or reduction in torque. Fluid system.-The pressure regulator valve is loaded in the positive upward direction by a spring 68 and by TV pressure 75 acting on an amplifier valve 52, and provided by a TV valve 53 loaded by engine intake depression. The cutback chamber 86, fornegative downwardloading, is fed with TV pressure 75 through a restrictor 85 smaller than the nozzle 54. With cut-back pressure operative, the upward TV pressure is blocked from the amplifier valve 52 at a port 74. Electronic circuit.-The solenoid 87 is deenergized at the cut-back point by a circuit, Fig. 3, supplied by a 10 volts positive line 28. Transistors 26, 31, arranged as a Schmidt trigger, are controlled by voltage signals Vc, Vt, the former, Vc, providing a positive signal which decreases with increase in vehicle speed, the latter, Vt, a negative signal which increases with engine torque under control of engine intake depression or throttle setting. Increase in speed, and/or reduction in torque, renders the transistor 26 non-conductive; 31 conductive; and 35, 37, 39 non-conductive, thereby de-energizing the solenoid line 42a to close the jet-nozzle 54 for line pressure cut-back. Diodes 29, 40 limit voltages across the transistors.

Title: Needle selection system for knitting machines
IPC: D04B15/70
Filed: 1972-10-05
Abstract: 1374776 Knitting machines STIBBE-MONK DEVELOPMENTS Ltd 5 Oct 1972 [13 Oct 1971] 47577/71 Heading D1C A circular or flat one or two-bed knitting machine with two or more knitting stations has, beneath the lower end of each needle, or a jack associated therewith, a horizontal spring wire which is selected in advance of each knitting station to pass above or below a control cam by an electromagnetically controlled armature which closes or does not close the normal pathway of the wires. The machine, if circular, may have a stationary or rotary cylinder and may have compound needles. In an arrangement similar to that described in specification 42437/71 two sets of alternately longer and shorter wires 13, 21 are provided fixed respectively at two levels in blocks 18 and corresponding to the needle tricks extending through extensions of the latter. Wires 13, 21 are respectively associated with spring wire armatures 23, 22 and cams 11, 12, 19 and 20, 27 all of which are mounted on brackets 26 removable through openings 14a in housing 14 which supports the cam cylinder. There can be more than two sets of wires e.g. 3 or 4 at different levels. When armatures 23, 22 are inoperative, their tips are covered by guard tips 20a, 19a of cams 20, 19 but, when operative, they block the gaps between cams 20, 27 and cams 19, 12. Wires 13, 21 are lifted against their own resilience by cams 11, 19, 20 so that the ends engaging the cams are biassed downwards. If armatures 23, 22, which are controlled by electromagnetic selectors 24, 25, are inoperative the wires will slide down through the gaps and be raised by the cams for the next selection. If armatures 23, 22 are operative, wires 13, 21 will be raised by cams 12, 27 to lift corresponding jacks 4 before returning to cams 11, 19, 20 for reselection. The lifting of jacks 4 moves butt 3a of tilting jack 3 into engagement with cam edge 9b and removes butt 3b from between cam 8 and edge 9a so that corresponding needles are not raised. Edge 29a of cam 29 pushes butts 3a out before the next selection. In a V-bed machine, the needles have knitting butts 31a a and extensions 31b each operated on by a spring wire 32, wires 32 being fixed in blocks 33 and having their ends guided between extensions of the trick walls of needle bed 30. When the carriage moves in direction F, wires 32 are all raised from normal position by cam 38 after which if armature 39 is blocking the gap between cams 38 and 40, wires 32 pass onto face 40a of cam 40 and lift the needles so that their butts 31a engage the clearing cam 42. If the gap is not blocked, the ends of the wires drop down and their associated needles are not raised. Electromagnetic selector 41 operates the armature 39. A similar arrangement controls stitch transfer. Preferably; the relaxed position of the spring armature is between two electro-magnetic pole faces and it is operative in contact with one face and inoperative in contact with the other.

Abstract: 1477816 Wells &c HALLIBURTON CO 20 Nov 1975 [23 April 1975] 47863/75 Heading E1F Multiple stage cementing apparatus for cementing casing in a well bore includes a casing valve which communicates the interior of the casing with an inflatable packer via a check valve and with the well bore via a pressure responsive valve. As described the casing valve includes a mandrel 12 having ports 26, a closing sleeve 58 which is initially fixed by spring collet 68 in a position in which ports 60 are aligned with ports 26, an opening sleeve 150 initially held by shear pins 106 in a position covering ports 60 and a release sleeve 98 initially held by shear pins 132 in a position to hold the spring collet 68 of the closing sleeve 58 engaged in a groove 64 in the mandrel 12. The ports 26 communicate with the upper part of an inflatable packer assembly 140 which in turn communicates with the inflatable packer unit 220 through a downwardly facing seal 194 which acts as a check valve and with the outside of the packer via a normally closed pressure responsive valve consisting of a piston 176 which is initially held by shear pins 184 in a position covering ports 170. In use a plug 244 (Fig. 4) is passed down the casing 236 and lands on the opening sleeve 100. An increase in pressure in the fluid in the casing shears pins 106 and moves opening sleeve 100 downwardly to uncover ports 60, 26, thus allowing the fluid to pass through check valve 194 and inflate the packer 140. A further increase in pressure shears pins 184 and raises the piston 176 to open the ports 170. A cement slurry is then passed down the casing to cement the well bore annulus above the inflated packer. A cementing plug 246 (Fig. 6) follows the cement slurry and lands on release sleeve 98, shearing pins 132 so that release sleeve 98 moves downwardly and permits the collet 68 to move out of the groove. Further pressure causes the release sleeve 98 together with the closing sleeve 58 to move downwardly, thus closing ports 26. In a modification (not shown) the casing. valve consists of a single valve sleeve which can be moved between its open and closed positions by tools carried by a pipe string passing through the casing string.

Abstract: 1366793 Card selector K TAKEDA 27 Oct, 1972 [30 Oct 1971] 49743/72 Heading G4M A card selector for cards having identifying notches in their lower edges has a set of bars corresponding to all possible notch positions and one bar spaced from the set and situated where no notch exists on which the lower edge of the cards rest. All the bars are raised for selection with the one bar and selected bars of the set being raised further so that cards having notches corresponding to the selected bars are raised further at one end by the one bar than at the other end by the selected bars to cause a lower corner to extend beyond the stack. When the bars are lowered the said corner is engaged on a ledge to further separate the selected card or cards. The set of bars (of which b4 is shown, Fig. 5) contain inclined slots receiving bar supporting shafts 12. The one bar B receives supporting shafts 14 in similar inclined slots. A reversible motor M via a rack and pinion mechanism oscillates a rack 19. At each end of the rack are pinions 20 coupled to a cam 22 arranged to raise a support 15 carrying the shafts 12 and 14. The bars (of which b2 is shown in Fig. 8) have inclined ends engaging a similarly inclined surface C on a rotary cam E2. The cam is spring- loaded into engagement with the bar but is normally rotated when the bar is raised. For selected bars a solenoid is operated to engage abutments f1, f2, f3 to prevent rotation of the cam and move the bar to the left to raise the bar as shaft 12 slides in slot 13. The one bar B engages a cam that is fixed against rotation. The cams have three abutments to allow solenoids for three adjacent cams to be angularly displaced (Fig. 10, not shown) since the solenoids are thicker than the cams. The inclined cards rest on the step formed by surface 11 (Fig. 5).
