Title: Switching matrix release delay circuit
Inventor: DRAAYER JOHANNES
IPC: H04Q3/54
Filed: 1970-10-13
Abstract: 1287180 Automatic exchange systems AUTOMATIC ELECTRIC LABORATORIES Inc 13 Oct 1970 [20 Oct 1969] 48647/70 Heading H4K In a reed relay switching network in which a signal path is held by the series interconnection of the hold windings and associated closed contacts of the selected crosspoint relays in each stage, the hold and signal paths include contacts of a switching relay which at the end of a call is released first so as to ensure that when the crosspoint relays subsequently release there will be no current flowing through their contacts. The delayed release of the crosspoint relays is   achieved by connecting the earthy (junctor) end of the hold path to negative battery by a normally reverse biased diode D1. When the holding contact H3 of switching relay H opens at the end of the call, the collapse of the magnetic field in each crosspoint relay's holding coil results in the creation of a voltage of opposite polarity to that which created it and consequently there is a current flow via D1 which tends to hold the crosspoint relays on for a short period. During this period, the switching relay's contacts H1, H2 in the speech signal path should open thereby terminating the flow of loop current through the contacts of the crosspoint relays. (This assumes that the call is released from the " succeeding equipment side " of the trunk circuit since, if the subscriber ST1 releases the call, the loop is automatically broken and the problem of opening the crosspoint contacts under currentless conditions does not arise). The exchange system uses a No. 1 ESS type control with subscriber line monitoring being effected with the aid of ferrods F1.

Abstract: 1,244,700. Feeding webs. SIGNODE CORP. 7 Oct., 1969 [7 Oct., 1968], No. 49267/69. Heading B8R. [Also in Division B3] A device for dispensing a coil of strapping comprises a motor 16 coupled to drive a rotatable carrier 28 and control means including a movable sensor 50 for the motor 16. The coil C is positioned in the carrier 28 and the innermost winding of the coil is passed through a tube 72 of the sensor 50. When the strapping is required, tension is applied to the outwardly extending length of the strapping which causes the tube 72 to swing inwardly towards the central arm about a pivotal support 76. As the tube 72 swings inwardly, pin 82 will swing about the pivotal support 76 to engage and close a lever 64 of a switch 48. This actuates the motor 16 which drives a friction wheel 20 to turn the carrier 28 until a sufficient length of the strapping has been obtained, whereupon the tension in the outwardly extending length of the strip will be relieved. Owing to the resilient curvature of the strapping, the tube 72 will swing outwardly towards the innermost winding of the coil C which causes the pin 82 to disengage switch lever 64 and open the switch 48 to stop the motor 16. The rotation of the carrier 28 will be stopped immediately by the frictional drive wheel 20 which serves as a brake.

Title: Tubular knitted fabric
IPC: D04B9/46
Filed: 1970-10-23
Abstract: 1351616 Knitting BENTLEY ENG CO Ltd 6 Oct 1971 [23 Oct 1970 2 Dec 1970 12 March 1971] 50450/70 57198/70 and 6925/71 Headings D1C and D1K In a method of closing a tubular knitted fabric, e.g. a stocking, on a circular knitting machine, the fabric is shaped by stitch transfer, and the last course of stitches drawn together by a yarn or yarns passing through them and pulled tight. In a first procedure a stocking is knit on a cylinder and dial machine, and the last course of stitches transferred to the dial. A needle and cooperating looper sew a seam through the loops, which are cast off one-by-one. Consequently as a constant pull is maintained in the fabric, adjoining wales are pulled together. When the last loop is cast off, the seaming yarns are cut and may be heat-set to ensure a permanent closure. In a second procedure the wales in the toe are progressively reduced by stitch transfer. After knitting the last course the needles 28, Fig. 5, are raised to an inactive level. The yarn Y1 is wrapped around the needles and severed. The loop 33, Fig. 6, on the last needle to knit is pulled through the previous loop 24' by a hook 34. One-by-one the needles knit the yarn, and the free end Y2 is drawn through previous loops. The free end is drawn through the last loop, to lock the yarn Y1. A single strand draw-thread is thus formed through the last course. Loops are transferred with the aid of instruments 109 Fig. 11 mounted in a cylindrical bed (108 Fig. 8 not shown) inside the upper cylinder. The bed is rotated at a slightly different rate to the cylinders so that a loop engaged by an instrument is spread to the desired extent in a quarter turn. The bed is rotated at the desired rate or rates by a gear train or trains (123-6 Fig. 9 not shown) from the cylinder drive shaft (106). If a loop is to be transferred its needle 135 is transferred to the upper bed 101 and engaged by the instrument. When spread it is engaged by a receiving needle 134a, and released from the instrument and previous needle. In a third procedure Figs. 20, 22 the last loop 143a of the last course is repeatedly passed through loops of that course. The needle 135a carrying the loop 143a is transferred to the upper cylinder and holds the loop on its latch 142 which is supported on guard 144. The loop is enlarged by instrument 109. The receiving needle 140 draws a loop of yarn through its old loop 147. Needles are transferred to the upper cylinder one at a time so that their loops can be spread and then taken by an adjacent needle in the lower cylinder. The last needle to knit, knits a chain to secure the yarn, which is then cut. Its free end is drawn through the previous loop, as the fabric is drawn down. In a modification of the above procedure (Figs. 29-34 not shown) movement of the lower slider cooperating needle latch ensures that the loop is spread while in the needle hook, rather than supported on the latch.

Abstract: 1362924 Leak testing KRAFTWERK UNION A G 2 Nov 1972 [5 Nov 1971] 50644/72 Heading G1S [Also in Division H2] In an electrical machine, such as a turbogenerator, which has a main gas tight housing supplied with a gas and a water cooling circuit, leakage in the water cooling circuit is detected by adding an indicator such as helium or tritium to the gas or the cooling water, and detecting the presence of the indicator in the cooling water or gas respectively. In Fig. 1, hydrogen is passed through housing 5 to cool the rotor 3 and the laminations of stator 2, and water flows through the stator windings 6. Helium is added to the gas in housing 5 via valve 16, and a helium detector 17 is provided in the cooling water expansion tank 12. In an alternative arrangement, Fig. 2 (not shown), tritium is added to the cooling water, and the hydrogen from housing 5 is passed through a counter. In an alternative construction Fig. 3 (not shown) the cooling water containing tritium passes through both the stator and rotor windings of the machine. In Fig. 4, the stator, the rotor and the stator laminated core are supplied with cooling water into which helium or tritium is injected at 18. The air gap 25 is sealed at 26 and 27, and is evacuated, while the machine housing 5 is filled with natural gas. Leakage of the cooling water into hqusing 5 and into air gap 25 is detected at 20 and 29 respectively.

Abstract: 1,083,736. Copy-milling. DROOP & REIN. Dec. 14, 1964 [July 9, 1964], No. 50857/64. Heading B3K. [Also in Division G3] In a tracing arrangement for a copy-milling apparatus, deflection errors of a tracing point 1 are compensated by superimposing signals, proportional to the deflection of a core rod 7, on the control signals from a tracer-point deflection sensing element 16, 19. The tracing point 1 is carried on a member 3 which is subject to angular deflection about a ball-joint 2. An annular bearing 6 in a free-from-play engagement with a flange 8, causes angular movement about a ball-joint 14 of a swashplate 9. The angular movements of the swashplate 9 relative to a plate 18 rotatable about a core rod 4, causes variation in the air-gaps of electromagnetic transducers, comprising elements 16, 19, which are connected in bridge arrangements, not shown, providing X and Y co-ordinate control signals for the copy-miller. Continued movement of the member 3 causes the annular bearing 6 to engage a flange 7 on the core rod 4, deflection of which causes vertical movement of shaft 23 in a fixed bearing 24. The shaft 23 carries an armature 27 movement of which from a null position causes the compensating signals to be developed by coils 28, 29 which are (a) superimposed on the control signals and (b) applied to a motor 30 to cause a compensating rotation of the plate 18. A mechanical lock 32, 33 is provided to prevent angular movement of the swashplate 9, the control for the copy-miller being derived from the axial movement of shaft 23 caused by movement of the core rod 4. In another embodiment the swash-plate is replaced by a cylindrical member rotatably mounted on the member 3, the control signals being developed by radial movement relative to the core rod 3, the motor 30 then driving the cylindrical member.

The compound or mixture of compounds I is obtained by reacting a compound of formula II with a compound of formula H 2 N-R 2  (III) or a mixture of compounds of formula III in a 1 : 1 or 1 : 2 molar ratio. If a single compound of formula III is reacted with a compound of formula II in a 1 : 1 molar ratio a mixture comprising compounds where R 3  is O and compounds where R 3  is >N-R 2  is obtained. With a 2 : 1 ratio a substantially pure product where R 3  is >N-R 2  is obtained. The reaction where R 2  is other than H is carried out in anhydrous alkane acid or anhydride in the presence of an alkane acid alkali metal salt. When compound III is ammonia the reaction can be effected in an aqueous alkaline medium. Sulphonation of the products by known methods can be carried out. When sulphonic groups are present in R 4  the compounds are useful as anionic dyes. Where one or both of R 2  and R 5  are other than hydrogen and no sulpho groups are present the products are useful as disperse dyes. The compounds wherein R 2  and R 5  are hydrogen are useful as pigments for plastics, e.g. polyethylene, polystyrene, PVC, rubber or synthetic leather, coatings. lacquers, spinning solutions, printing inks, paper. The pigments can be improved by after-treatment at elevated temperature in solvents such as chlorobenzene, nitrobenzene, dimethylformamide, acetic acid, glycol or quinoline. In an example (62) a different method of preparation is used in which a compound of the formula a is heated with aniline in butanol while passing in ammonia gas. The compound obtained of formula is heated at 270 in diethyl phthalate to effect cyclization, giving a product of the formula

Abstract: 1367636 Photo-electric reflection measurements INFRA SYSTEMS Inc 27 Oct 1970 [28 Nov 1969] 50979/70 Heading G1A [Also in Division G3] In a dual beam reflection measurement apparatus for measuring a parameter, e.g. thickness, of an infrared transparent film C and in which the film is irradiated at a given angle O i  alternately by a beam which is strongly absorbed by the film and an unabsorbed reference beam, a photo-detector 11 is arranged to receive only the diffusely reflected components R d , reflected at angles other than O i , of the two incident beams to provide a ratio output indicative of the parameter. In this way errors due to interference in the film are removed. Most of the diffusely scattered components derive from the under surface D of the film, but there may be some such scattering from within the substrate B. The alternating beams are provided by a single source and an associated rotating filter wheel 10. A switch 18 operated in synchronism with the filter wheel directs the output of the photo-cell, e.g. a photo-voltaic all or photo-resistor, into the appropriate reference (14) or measuring (15) channel, whose outputs are combined and displayed on a meter 17. The output from the analyzer circuit 16 may also be used to control the thickness d of the film as it is applied to the substrate. For thick polyethylene films, i.e. 0À010 inch 7 d > 0À0005 inch, the absorption wavelength is 2À30-2À60 Á, and the reference wavelength 2À25Œ 0À02Á. For thin polyethylene films, i.e. d < 0À001 inch, the absorption wavelength is 3À45 Œ 0À02Á, and the reference wavelength either 2À65 Œ 0À02Á or 3À75 Œ 0À02Á.

Abstract: 1,142,077. Making electrical connections; straightening wire. AMP Inc. 10 Nov., 1967 [12 Dec., 1966], No. 51270/67. Headings B3A, B3E and B3Q. A press for crimping an electrical connector to an end 6 of a wire 4, Fig. 13, comprises a ram 38, Fig. 4, carrying a die 34, 36 over an anvil 28, 30, jaws 118, 120, Fig. 1, for straightening the wire, mechanism for operating the jaws and moving them, when open, towards a wire 4 adjacent the anvil so that they close about the wire, and mechanism for moving the jaws towards the anvil and relatively to the wire to straighten the wire and thus position it in a connector to be crimped. A strip 1 of connectors is fed to the anvil, each connector having limbs to be crimped to the end 6, adjacent limbs for gripping the insulation and a connecting land severed by a blade 22 on the ram. The press may be a removable part of a leadmaking machine (not shown) having a conveyer with pairs of spaced jaws 14, 16, Fig. 13, for gripping the wire. A housing 40 is attached by upper links 44 and a lower link 60 to guides 33 for the ram, and a follower 58 on the back of the housing is held against a cam 54 on the ram by a spring 52. Within the housing 40 is a slide 76 operated by a pneumatic cylinder and formed with a passage for a further slide 84 on which the jaws 118, 120 are mounted by a pivot 104. An adjustable eccentric abutment 86, 87 mounted on the housing 40, extends through slots 89, 90, 91 in the slides, and a spring 96 acts between the slide 84 and a pin 92 carried by the slide 74 and engaging slots 94 in the slide 84. Operation.-When the wire conveyer stops, the cylinder 72 is operated automatically for lowering the slides 74, 84 with the jaws 118, 120. Continued movement of slide 74, after slide 84 has been arrested by the abutment 86, causes arms 116, Fig. 1, on the slide 74 to close the jaws against the pressure of a return spring 114. The ram 38 is then lowered, moving the cam 54 past the follower 58 so that the spring 52 moves the housing 40 through an arcuate path and slides the jaws along the wire to straighten the wire, thus locating it in the connector before the connector is crimped. The arms 116 may be adjusted to vary the position of the jaws.
