Title: Improvements relating to power factor indicators for use in alternating electric current systems
IPC: G01R21/00
Filed: 1923-01-19
Abstract: 206,756. Chamberlain & Hookham, Ltd., and James, S. Jan. 19, 1923. Power factors, measuring.-In order to indicate the average power factor of a three-phase system provided with two single-phase energy meters, an index is operated by the joint action of the meters the index-actuating mechanism being periodically reset by means controlled by that meter which runs the faster on a balanced inductive load. A pair of sun pinions c, c , Fig. 1, driven by worms a, a<1>, on the two energy meters, are loosely mounted on a spindle b to which is attached a carrier d for a planet pinion e engaging the sun pinions c, c. On the spindle b is fastened a worm f driving a wheel h, Fig. 2, which is controlled by a spring i and operates a non-return pointer g through a pin j. The wheel h is mounted on a lever l which is rocked by an electromagnet m when the circuit of this is closed by the engagement of a contact p, Fig. 1, driven by the meter worm a, with fixed contacts q. The wheel h is thus disengaged from the worm f and is returned to zero by the spring i. Alternatively the mechanism described in Specification 104,924 may be employed for the periodic resetting of the index-actuating mechanism.

Title: Improvements in grooving machines
IPC: B23B5/48
Filed: 1948-01-21
Abstract: 639,431. Machines for cutting oil-grooves and the like. CROUCHER, H. J. S., and BLAMEY, K. Jan. 21, 1948, No. 1898. [Class 83 (iii)] A machine for cutting grooves (e.g. oil grooves) in the inner concave surface of work-pieces 24 of circular or arcuate sectional form comprises a rotatable tool-head 45, a tool-holder 55 rotatable therewith and extending in the general direction of the axis of rotation of the tool-head and pivoted for movement in a plane intersecting the tool-head and parallel to the axis thereof, and means for effecting the simultaneous rotation of the tool-head and progressive pivotal movement of the toolholder. A half-bearing liner 24, Fig. 2, of whitemetal or phosphor-bronze is held by clamps 22, 23, and may be supported by packing blocks on a block 21 which is carried by a slide 18, Fig. 1, and is capable of slight transverse adjustment in relation thereto in order to enable grooves to be cut which extend around only part of the liner. The slide 18 is mounted for single harmonic motion on horizontal bars 15, 16 attached to a pillar 10 and mounted at their ends in a yoke 12 which is supported by an extension 13 of the pillar. The slide 18 is secured adjustably by means of a screw 121 to a bar 117 adapted to be reciprocated by a bell-crank lever 109 which is actuated by a rod 105 secured to a slot 94, Fig. 3, in a crank-disc 93. The stroke of the slide can be varied by adjusting the throw of the rod-attachment 97, 102 to the crank-disc 93 against a scale 103 thereon. A pinion 50 is attached to the disc 93 which is driven by a hand lever 47 and pinion 49 engaging the pinion 50. The tool-head 45, Fig. 5, is driven by the pinion 50 and retained within a bearing 44 in the pillar 10 by a collar 128 engaging threads 129 thereon; while the tool-holder 55 is mounted on pivots 56, 57 in the bore of a sleeve 53 located within the tool-head. A tool 26, Fig. 2, on the holder 55 is fed radially of its axis of rotation by pivoted movement of the holder caused by a screw 67 and nut 72 connected by a link to the end of the holder. The screw 67 is turned by a gear-train 73, 74, 75 housed within a box formed by the pinion 50, an annulus 80, and a disc 83. The gear 75 projects through the wall of the annulus 80 and is actuated once during each revolution of the tool-head by co-operation with a stationary spring-loaded pin 90, Fig. 3, which can be withdrawn and a shaft extension 85 of the gear 75 engaged by a key to return the tool without rotating the head 45. The disc 93 can be attached to the pinion 50 in two different settings spaced apart by a right angle; one setting aligns the axis of the tool 26 with that of the slot 94 so that grooves curved in either direction can be cut depending upon the side of the slot to which the rod 105 is attached, and the other enables a straight groove inclined to the axis of the liner to be cut. By connecting the rod 165 to the centre of the crankdisc 93, a groove normal to the axis of the liner can be cut.

Title: Multiplex pulse communication system
IPC: H04B14/02
Filed: 1966-01-14
Abstract: 1,073,568. Multiplex pulse code signalling. MOTOROLA Inc. Jan. 14,1966 [Feb. 8, 1965], No. 1918/66. Heading H4L. In a multi-channel radio communication system wherein voice signals are converted into pulse signals as by delta modulation, a combination of frequency division and time division multiplex is used. At the transmitter, as shown in Fig. 1, the output signals of twentyfour delta modulators 11 to 34 plus a synchronizing signal 35 derived from clock 38 are arranged in five groups of five time division multiplex channels at 40 to 44 and converted into frequency-shift signals by appropriately keying the generators 50 to 59, each group being allotted a different pair of mark-space frequencies. The frequency shift signals are combined in time division multiplex at 60 and the resulting wave, Fig. 4 (not shown), which is frequency varied in steps around 70 Mc/s. is amplified at 62 and supplied to the transmitter 64. At the receiver, Fig. 2, the appropriate pairs of mark-space frequencies (which now tend to overlap in time) are selected by narrow bandpass filters (71 to 80) and applied to corresponding pairs of detectors (81 to 90). The detectors of each pair are oppositely polarized so that on combination in circuits (92) &c., a positive output is produced for a mark and a negative one for a space. The output of circuits (92) &c. are supplied via a relatively long time constant circuit (93, 94) to overcome the effects of fading, to demultiplexing circuits (95 to 106) corresponding to the channel grouping at the transmitter and the resulting signals are supplied to delta demodulators (1 to 24), the sync. signal being extracted at (109) to control the clock (110).

Abstract: 657,792. Variable pitch propellers; controlling aircraft. ROTOL, Ltd. Jan. 24, 1949, Nos. 1926 and 32985. [Classes 4 and 114] In a multi-engined aircraft installation in addition to the normal feathering controls for the variable-pitch propellers, a selective feathering switch is provided, which, when closed, operates the feathering gear of an engine which is not producing a minimum torque. The selective feathering switch 19 when closed, closes the switch 22, each blade of which connects lines 24, 25 for each engine. If one engine is failing to produce its minimum torque its switch 17 is closed, this operating solenoid 23 associated with that engine and thus, through contacts 34 closing the circuit of the feathering pump motor 12. The simultaneous disconnection of contacts 28, 29 breaks the feathering circuits of the remaining propellers so that only one propeller can be feathered at one time. A switch 18 on the engine throttle prevents feathering until a given throttle opening is reached.

Title: Improvements in knitting machines
IPC: D04B9/38
Filed: 1931-01-20
Abstract: 363,185. Knitting-machines. WEIDNER, R. I., 20, Richardson Avenue, and DEXDALE HOSIERY MILLS, both in Lansdale, Pennsylvania, U.S.A. Jan. 20, 1931, No. 1935. [Class 74 (ii).] A circular machine is provided with means for shifting the needles bodily with respect to the knitting cams to permit fashioning with different selected groups of needles and means for causing all intermediate needles to knit the yarn which would otherwise be floated as a result of the shifting of the needles. By this means a pair of complemental tapered toe tabs for a stocking can be knitted without a float yarn. The needle cylinder 20 is secured to its driving gear wheel 21 by a spring-pressed clutch latch 60 which is pivotally mounted upon the gear wheel 21 and has a downward projection 62 for engaging diametral slots 63, 63a in a ring 64 on the needle cylinder. The latch 60 is released when the cylinder is to be displaced 180‹ from its driving gear, as e.g. upon completion of the first toe tab, by a crescentshaped cam 65 under pattern control. A brake band 78, operated by a lever 79 is actuated to arrest momentum of the needle cylinder simultaneously with the withdrawal of the latch 60. The cams for actuating the usual long and short butted needles are also withdrawn or inserted under pattern control at this stage. To enable the float of yarn which would normally occur at the end of the fashioned toe tab T to be knitted, the needles 38a between the end short-butted needle 38 in action after fashioning and the longbutted needles 37 have medium length butts and are brought into knitting position immediately after the formation of the last course by the shortbutted needles. A needle depressing cam 90 controlled by a stop on the usual pattern drum is provided for guiding the medium-butted needles, which have previously been raised by the picker, into the path of the stitch cam 40, and is brought into action with a needle raising cam 91 and the cam 80 which lowers the long-butted needles into operative position. The cam 91 is provided with a surface 91b so that long-butted needles which have been raised by the cam can again be brought down upon reverse movement of the needle cylinder.

Title: Improvements in electrical sound recording apparatus
IPC: H04R15/00
Filed: 1947-01-24
Abstract: 650,769. Magneto - strictive apparatus. SYKES, A. F. Jan. 24, 1947, Nos. 2308, 2309, 33992, 34410 and 35237. [Class 40 (iv)] Magneto-strictive elements are arranged so that the vibrations of their free ends are brought together whereby they can be magnified. In a recording device, Fig. I (2308/47), a floating weight 12 supports a pair of magnetostrictive rods 10, carrying a bridge-piece 14 which carries a further magneto-strictive rod 11 energized by a coil in the opposite sense to the rods 10, whereby the vibrations are added. The rod 11 acts on a spring-pressed recording stylus 18, the depth of cut being set by adjusting a slide-ball 30 and, for fine adjustment, rotating the whole device by a micrometer screw about the axis 31. A pair of magneto-strictive rods may be used, Figs. I (33992/47) and VIA (33992/47), responding in like manner to alternating speech currents and differentially to a superposed direct current. Additional coils provide a negative feed-back to the amplifier. The recording head is rocked counterclockwise away from the blank by operation of a lever 52 which causes a cam to act on a leafspring 50. Depth of cut is adjusted coarsely by movement of a slide 43 and sliding shoe 30, held in adjusted position by a clamp 45. Fine adjustment is effected by a hand wheel 47 which rotates the head about a screw 46. Lateral twisting of the rods 10, 10a is prevented by a roller 136 and a spring 20. In an alternative construction, as shown in Fig. II (34410/47), a single compound laminated rod 10, 10a is gripped at the centre and the vibrations of the ends are brought to the centre by light rods 11a of aluminium to produce magnified lateral vibrations. The floating weight 12 is made in two parts, one attached to the compound rod and the other to the light rod, the two parts being connected by an oil dash-pot which acts solely as a temperature-compensating device. The magneto-strictive rods may be arranged as a U or V. In all cases the rods may have two windings, one carrying a constant potential polarizing current and the other the acoustic signal, or a single winding carrying amplified acoustic signals. Reference is made to Specification 160,223 [Class 40 (iv)].

Abstract: 1,195,791. Klystrons. VARIAN ASSOCI. ATES. 16 Jan., 1968 [27 Feb., 1967], No. 2418/68. Headings H1D and H1W. A temperature-compensated iris coupling, for incorporation in a klystron cavity for example, is formed by a first apertured metal member, within the aperture of which is brazed an apertured insert of a different metal of higher thermal expansion coefficient and ductility, the aperture in which defines the iris. The expansion of the first, less ductile, metal, e.g. steel, limits the expansion of the insert, e.g. of copper, the annular width of the insert being chosen, in relation to the thermal expansion coefficients of the two metals, to maintain substantially unchanged iris dimensions at a typical operating temperature, e.g. 100 C. If the insert is in the form of a thin sheet, it is slotted, as shown, from its inner periphery, to avoid buckling. The arrangement is described with reference to circular, rectangular, or oval irises employed in window structures incorporated in a reflex klystron to couple the evacuated cavity to an output waveguide, to an external cavity tuned by a plunger (Fig. 1, not shown), or to a cut-off waveguide tuning arrangement (Fig. 7, not shown). Numerical examples are discussed.

Jan. 29, 1934, No. 2975. Convention date, Aug. 21, 1933. [Class 120 (ii).] In the cross winding of yarns and threads wherein the number of revolutions of the winding spindle 5, Fig. 1, decreases as the diameter of the package increases while the drive ratio between the spindle 5 and the thread guide 23 remains constant, a belt 4 passing over a grooved tension roller 6 is slung round the driving pulley 3 and drives the friction disc 2, the belt 4 being shiftable on the pulley 3 in order to vary the angular velocity of the winding spindle 5. The roller 6 is mounted on a bent lever 7 supported on a member 10, Fig. 3, which is slidably mounted on a rod 12 by a slot 11 and is formed with a second slot 13 engaging a stud 14 on an arm 15 fastened to the end of the rod 12. The other end 12<1> of the rod 12 is connected by links 18, 20 to a member 21 pivoted on a shaft 22, Fig. 4, and carrying the thread guide 23. As the package grows the guide 23 is forced outwardly and through the intervening linkage the member 10 carrying the roller 6 is moved to the left, Fig. 3, thus shifting the belt 4 towards the circumference of the disc 2 and reducing the angular velocity of the package. The disc 2 is moved into its operative position by means of a rod 24 engaging a lever 26 pivoted at 27, Fig. 1.
