[Also in Division C1] Apparatus for making an extrusion nozzle 14 of an orificed stream feeder comprises a shearing station 20 where tubular stock 23 is cut into short lengths and deforming stations 24, 30, 32 where the lengths are shaped. The stock 23 is platinum or platinum alloy and is fed through a stationary block 35 at the first station into a bore of a lower movable block 37. The bore has a spring 46 which ejects the cut of length. The lower block is moved by a pneumatic motor or a cam (not further described) to shear the stock and the cut-off length is transferred to the next station 24. The dies 51, 53 at the second station shorten the length of stock 26, Figs. 3 and 4 (not shown). The stock is transferred to the next station 30 for further upsetting. Figs. 5 and 6 (not shown). The end of the shaped stock is coined at the fourth station 32 by a coming pin 106 which co-operates with the dies 91, 93 at this station. The dies 91, 93 are the same shape as the dies at the previous station and the pin 106 shapes the bore of the stock and smooths the end. The upper dies 51, 71, 91 are moved by press rams and the lower dies 53, 73, 93 have ejector pins 67, 87, 107 operated by cams. The coining pin 106 forms part of the ejector pin at the final station. The coining station may be omitted and the nozzle end smoothed by grinding. The head 120 of the nozzle 14 has an annular ridge 124 approaching a knife edge which is welded to a base plate 16 of the stream feeder. The passageway 128 has an outward taper 127 at the head end which expands inwards during the welding. The nozzles 14 are positioned on the base plate 16 by a jig 135, Fig. 10 (not shown), with ceramic pins 137 which extend through the orifices 18 in the base plate. The base plate 16 is made of platinum or platinum alloy and the jig 135 of conductive material. The jig 135 acts as one electrode and a second electrode 150 is abutted with the head 120 of the nozzle for resistance welding. During welding the nozzle head expands on to the pin 137, Fig. 13 (not shown). In an alternative embodiment of welding apparatus, Fig. 14 (not shown), the upper electrode (160) has a pin (170) on to which the head expands. The nozzle 14 is held in the electrode by a suction pump. The welding may be performed without the pins 137, (170).

Abstract: 1290822 Two-wire switching networks INTERNATIONAL BUSINESS MACHINES CORP 14 Jan 1971 [28 Jan 1970] 1788/71 Heading H4K A two-wire switching path is set up by connecting winding WA1 of transformer TA to winding WB1<SP>1</SP> of transformer TB by way of a single wire and by connecting winding WAl<SP>1</SP> of TA to winding WB1 of TB by way of a second single wire path, the single wire paths being switched with cross-points comprising unidirectionally conductive elements CR poled in one sense in one wire and in the other sense in the other wire. The cross-points are controlled semi-conductor rectifiers in matrices of a fourstage network. Transformers such as TA serve extension lines while transformers such as TB serve main exchange lines. Path selection is effected by cross-point marking wires G1 to G4, each of which marks the pairs of cross-points common to a row of a switching matrix, and by means of junctor circuits J provided on the links between the second and third stages. With markings on leads G1 and G a pulse is applied to transistor FP in junctor J and cross-points CR1, CR2 break down and conduct. Markings on G1 G2 are withdrawn and markings on G3, G4 applied with a pulse applied to transistor FQ in the junctor so that CR3<SP>1</SP> and CR4<SP>1</SP> conduct, Markings G3, G4 are withdrawn and markings G1 G2 are reinstated so that crosspoints CR1<SP>1</SP>, CR2<SP>1</SP> and line switch CRA conduct, CRA being primed to conduct by conduction in the other line as detected by transistor TRA. Markings G1 and G2 are withdrawn and markings G3, G4 are reinstated so that cross-points CR3, CR4 and line switch CRB conduct, CRB being primed by conduction in the other line as detected by transistor TRB. With conduction established from end-to-end of each wire the junctor J can stand idle with transistors FP and FQ switched off. Current in each wire of the path is detected by leads SA, SB, in order to test that the path holds up following junction feed standing down. Release is effected by switching on transistors DP, DQ in the junctor so that the earth side cross-points are starved of current and switch to open circuit.

The foil, which may be of copper or aluminium, is wound around the mandrel 1 with the turns of the foil separated by insulating material 4. The insulation may be formed by anodizing the aluminium. The mandrel is provided with a groove, which houses either a conductive rod 2, extending the length of the mandrel, or the tightly rolled inner end of the foil. The outer end of the foil may be left free or it may have a conductive rod secured thereto. An adhesive may be added during winding or the roll may be impregnated with a suitable liquid substance, which is subjected to a hardening treatment to form a machinable block 14. The coil is cut by boring a hole 10 through the block 14 and a cylindrical cut 11 is then made concentric with the hole to form a cylindrical coil, which comprises a pair of saddle coils. The cut coil is de-burred in an etching bath to prevent short-circuiting at the cut faces. Saddle coils may be made with more than one radius of curvature to suit electron beam devices not having uniform cylindrical shape. Two cylindrical coils are mounted concentrically over the neck of a cathode-ray tube and are connected to sources of deflecting waveforms.

The tube 13 is extended into the container by remote control, the piston 15 being raised to open partially the ports 14 so that liquid, e.g. petroleum, flows through the tube (13), Fig. 6 (not shown). The piston 15 is raised further only when liquid has covered the bottom of the tube (13), Fig. 7 (not shown), thereby preventing foaming, and again reduces inflow before the container is full. The tube 13 is retracted in response to a signal from a device metering the quantity of liquid filled thereby cutting off the liquid supply. As shown in Fig. 3, the piston is shaped to catch liquid trapped in the tube slots 14 which drains via a non-return valve 21 into the container being filled. In a modification the piston serves only as a scavenging device and the liquid flow is halted by external means rather than by retracting the tube 13.

Abstract: 1347972 Determining roughness M P RUBERT 21 May 1971 [26 May 1970] 25115/70 Heading G1M An instrument for assessing the roughness of an edge or surface 29 has a probe, preferably in the form of a thin spring blade 12 tipped with diamond or hard steel, which is movable from between a cover 24 and the tip 28 of a support 10 into engagement with the edge or surface at any desired angle. At low angles (dotted lines) the blade 12 is deflected by the surface, but after progressively increasing the angle, a critical angle is found, the value of which depends on the roughness, at and above which the blade will yield or buckle, e.g. as at 27. This critical angle can be measured directly e.g. with a calibrated arcuate spirit level located in position 11 or by using a fixed arcuate scale co-operating with a pointer on the instrument; or, as shown, a scale 36 over which a weighted and possibly gear-driven pointer moves may be directly calibrated in units of roughness. The zero of the scale may be adjustable to allow the testing of inclined surfaces. Alternatively the yielding of the blade can be detected by pneumatic, magnetic or electrical means, or if the blade tip is connected to a compression spring this spring can provide magnetic or mechanical indication of the yield point. The blade 12 is preferably moved by a trigger 22 against the bias of spring 23, but may be moved by a manually-operated solenoid or other electrical, magnetic or fluidic means.
