Title: Bundle tying machine
Inventor: KIWI WALTER
IPC: B65B13/08
Filed: 1961-07-13
Abstract: 947,093. Sealing. R. H. HOOD CO. July 13, 1961, No. 25482/61. Heading B6P. [Also in Division B8] Apparatus for applying and securing a cord in encircling relation to an article comprises cord end holding means for retaining a lower end of the cord in gripped position, reciprocable needle means for guiding and holding the cord and after it has been passed round the article advancing it to a position for engagement by said holding means, a member for impelling the cord for gripping engagement by said holding means, and members applying a clip to parallel portions of the cord. The apparatus includes a reciprocating needle 21 having a cord T passing from a supply slidably through it and a pair of plates 94, 97 which co-operate with a third plate 103 to hold the cord T as shown in Fig. 10. With the needle in a raised position and the lower end of the cord held by the plates an article, e.g. a stack of box blanks is passed from left to right, as shown in Fig. 2, to fold the cord into U-form around three sides of the article in which position the article contacts a switch 147 to commence the operations of the machine. The needle is lowered to the position shown to pass the cord round the fourth side of the article. The plate 103 is moved to the right (Figs. 2 and 11), to engage both portions of the cord to pull them into gripping relation with the plates 94, 96. The clip K is applied to the parallel portions of the cord as follows. A strip 26 of metal is fed from a roll by a reciprocating block 27 mounted on a slide 41 which is connected to a piston and cylinder assembly 48. The assembly also reciprocates a block 53 having a pair of clip die members 60, 61 attached thereto. The block 27 has a roll 36 biased by a spring 37 into wedging engagement with the strip 26 so as to cause feeding of the strip 26 as the block moves to the right. A second wedge roll 39 may also be provided to prevent return feed of the strip. The lower clip die 61 co-operates with a die press 31, 32 to fold a clip forming portion of the strip into U -form, the partially formed clip remaining attached to the strip by its central portion 16 (Figs. 2, 4). The upper die member 60 has a central portion 65 which severs a partially formed clip from the strip and side portions 66 housing resilient buffers at 67 which retain the side portions 17 of the clip in position for engaging the cord. The attaching of the clip to the cord is accomplished by the die member 61 pressing the clip around the cord and into contact with a further die member 76. The cord is severed just below the clip by a cutter 132 co-operating with a fixed blade 137. The cutter is rotated to cut the cord by a reciprocating pusher bar 127 operated by the assembly 48 and is returned to its original position by a spring 135. The needle is then raised again to complete the cycle and finally the machine switches itself off. The article must be removed from the apparatus to allow the switch 147 to open before the cycle can be restarted.

Title: Improvements in and relating to high frequency wave transmitting apparatus
IPC: H01Q13/02
Filed: 1945-10-01
Abstract: 608,499. Wave-guides; directive radio systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 1, 1945, No. 25484. Convention date, Oct. 2, 1944. [Classes 40 (v) and 40 (vii) Apparatus for transmitting high-frequency energy comprises an elongated wave-guide of the hollow pipe type closed at one end, means for supplying energy to the other end, means for radiating energy from the guide, and means for minimising reflection of energy from the one end back through the guide including an external path arranged for returning energy from the one end to the other end in correct phase to reinforce the energy supplied to the guide. In Fig. 3, energy from a generator is fed through a wave-guide 14 into one end of a semi-cylindrical guide 3 lying alongside a second semi-cylindrical guide 4. Guide 3 communicates with guide 4 through a slot 12 near one end, and through a slot 13 in guide 14 which is arranged opposite an elongated aperture 11 in guide 4. Apertures 5 arranged at intervals along the guide 3 feed energy through guides 7 to a set of horns 6. To ensure a uniform flow of wave energy along guide 3 without reflection, end pistons 17 are adjusted so that energy reaching the end of guide 3 passes through slot 12 into guide 4. Piston 16 is adjusted so that this energy passes through slot 13 back into guide 14 and hence into guide 3. Guide 14 is adjusted so that the distance between slots 12 and 13 is such that the energy fed back through slot 13 is in phase with energy flowing in the guide 3. The beam produced by the array of horns 6 may be swung through an angle by altering the amounts of energy passing through individual apertures 5. This is done by two motor-driven metal cylinders 22, 23 which surround the guides 3, 4 and pass between the apertures 5 and the sets of guides 7. Cylinders 22, 23 are formed with a series of slots, Fig. 4 (not shown), which pass successively before apertures 5 and control the relative amounts of energy of different phase passing to the horns 6, thus causing the emitted beam to swing from side to side. For a fixed beam, individually adjustable rings surrounding the guides may be placed to obscure the apertures 5 as required, Fig. 2 (not shown).

Abstract: 170,833. Seguin, A. Oct. 23, 1920, [Convention date]. Counting-apparatus; numeral-bearing elements. -The numeral wheels 3, 4, 5 are of light construction, for example of celluloid, and are actuated through driving-discs 3<a>, 4<a>, 5<a> secured thereto. Transfer mechanism.-Carry-over is effected by a tooth 10 carried by a spring 9 secured to the lower wheel. A cam-disc 6 slidably but non- rotatably mounted on the flatted spindle 11 holds the tooth off the driving-disc of the next higher wheel except at transfer when the cut-away part 6<a> allows the tooth to engage one of the notches 17. Zeorizing-mechanism.-The spindle 11 has a bearing at one end in the first numeral wheel 2 and at the other in a slidable knob 12 enclosing a spring 15. In order to zeroize, the knob is pushed in to disengage a disc 13 carried by it from a pin 14 on the casing and is then rotated backwards. The numeral wheels being in frictional contact under the action of a spring 16 with the cam discs 6, the rotation of the latter drags the numeral wheels back to zero position as determined by contact of teeth 19 with blade springs 18.

Title: Improvements in and relating to spinnerets
Inventor: PICKERING ERNEST GEORGE
IPC: D01H13/04
Filed: 1952-10-10
Abstract: A spinneret suitable for the extrusion of nylon and similar melt-spun materials comprises a relatively thick body portion or disc having therein a number of holes or bores of relatively large diameter uniformly tapered throughout their length towards the spinneret face, and a non-precious metal insert member having therein a single preformed extrusion orifice located in each of the holes or bores, the insert member being correspondingly externally uniformly tapered so as to engage tightly with a force fit within its bore and be retained therein without mechanical or other securing means.  The extrusion orifice comprises a tapered inlet portion and a cylindrical parallel-sided capillary outlet portion of reduced diameter joined at its upper end to the lower end of the inlet portion through the intermediary of a tapered portion, the angle of conicity of which is greater than that of the inlet portion.  The length of the insert members is equal to the thickness of the body portion or disc and they are so located in their holes that their upper and lower surfaces are flush with the upper and lower surfaces respectively of the body portion or disc.  Should one or more of the extrusion orifices become clogged or damaged in use, it is not necessary to replace the entire spinneret, but only to force out of the body portion or disc the affected insert member or members and to fit a new insert member or members into position.  The spinneret body portion or disc and the replaceable insert members may be made of any suitable non-precious metal, such as stainless steel, chromium-steel alloy, or nickel alloys such as nickel-iron alloys.  The spinneret may consist solely of a relatively thick disc provided with extrusion orifices as above or may be in the form of a cup of which the bottom wall constitutes the perforated disc.

Title: Improvements in and relating to the manufacture of electrical components by coating of metal on to an insulating substrate
IPC: C23F1/02
Filed: 1962-07-06
Abstract: Electrical circuit components e.g. resistors, are made by depositing a layer of a first metal on an insulating substrate e.g. heat-resisting glass, preferably by sputtering, and then a further layer of a second metal, part of which is subsequently removed.  The first metal may be Ta, W, Ti, Cr, Mo, or nichrome, and is of higher electrical resistance than the second metal e.g. Au, Pt group, Ir, Ag, Ni, Al, and Cu.  For example, glass is sputtered cathodically with a layer of Ta, and then similarly coated with Au, both steps being effected in vacuum or in argon gas.  A photo-sensitive resist is applied, and a desired pattern formed using U.V. light and a photographic negative as stencil. The unexposed resist is removed, and the exposed gold pattern etched to expose the Ta layer the exposed resist layer being protected by heating at 135  DEG C.; alternatively the Ta layer may also be removed, the exposed resist removed and a further pattern formed on the remaining gold layer, which is again etched to expose the lower gold layer.  A copper mask may be used by applying it to the substrate and sputtering the Ta and Au layers through the mask which is then dissolved away.  An apparatus is described in which the heated substrates are in turn brought under the separate sputtering zones.  A resistor is also illustrated of a tantalum strip coating on glass with thick gold conductor tabs of low resistance.
