Title: Ohmic contact and electrical interconnection system for electronic devices
Inventor: CUNNINGHAM JAMES ALAN
IPC: H01L23/522
Filed: 1968-11-08
Abstract: 1,243,247. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 8 Nov., 1968 [4 March, 1968], No. 52979/68. Heading H1K. The tracks in the uppermost interconnection level of an integrated circuit consist of a layer of tungsten overlaid by a layer of a higher conductivity metal such as gold or copper. With silicon devices, tracks in the lowermost level and having a layer of tungsten may contact the semi-conductor since tungsten makes good ohmic contact (without the need for alloying) when deposited on silicon, especially when the latter is heavily doped. A very thin intermediate layer of platinum silicide, aluminium, or titanium may, however, be provided-this layer may be absrobed by the adjacent tungsten. Fig. 9b illustrates a very small portion of an integrated circuit complex (shown more completely in other Figures) and shows a connection between two different levels of metallization. The passivated semi-conductor body bears a first interconnecting track consisting of a first layer 55a of tungsten, a second layer 55b of gold or copper, and a thid layer 55c of tungsten. The track runs beneath insulation 56 which may consist of silicon oxide, silicon nitride, aluminium oxide, or an organic material. The second track (which forms part of the uppermost interconnection level) has a lower layer 57 of tungsten and an upper layer 58 of gold. The third layer 55c of the first track is etched away where the tracks are connected together. In a variant the first track is a single layer and consists of tungsten. When there are tracks at several levels all except the uppermost may be tri-layer tracks, the uppermost track having the specified two-layer structure. The etchant used for tungsten is an aqueous solution containing 5% K 3 Fe(CN) 6  + 1% Na 2 B 4 O 7 .10H 2 O. The etchant used for selectively etching gold in the presence of tungsten is an alcoholic solution of KI 3 .

Title: Method for sorting objects
IPC: B23Q7/12
Filed: 1970-11-12
Abstract: 1336569 Sorting apparatus H SCHMID O HENGARTNER H SCHMID and W SCHMID [trading as HEINRICH SCHMID] 12 Nov 1970 [13 Nov 1969] 53829/70 Heading B2H  For sorting objects which are of substantially the same thickness and which differ from one in the degree of roughness of two oppositely situated surfaces of each such object, the objects are fed between entrainment surfaces of a pair of driven entrainment members, the entrainment surfaces at least partially overlapping each other and at least those overlapping portions of the entrainment members moving in different directions. As shown in Figs. 1 and 2, the entrainment members are constituted by discs 1, 2 made of flexible or resilient material, e.g. plastics, secured to drive shafts 3, 4 rotatably mounted at one end of arms 5, 6,. the shaft 4 being capable of slight axial displacement. Arm 5 is pivotably mounted at 9 and held in a horizontal or inclined position by a clamp 21. A rod 10 is longitudinally displaceably mounted within the other end of the arm 6 is longitudinally displaceably mounted within the rod 10 and is fixed in any desired position by a clamp 23. In the operating position shown, the discs 1, 2 are horizontally disposed to partially overlap each other at 14. An object stripper 11 is arranged a small distance above the lower disc 1 and extends outwardly from the central region of the disc. For sorting flat objects in terms of their rough and smooth faces or sides, the discs 1, 2 are rotated in the same direction and the objects are placed at location B upon the lower disc 1 which entrains the objects into the overlapping zone 14. Objects having for instance a rough surface directed upwardly will, at the zone 14, be entrained by the upper disc 2 and ejected in the direction of the arrow C. On the other hand, objects with rough surfaces directed downwardly, will be entrained by the lower disc 1 and transferred through the zone 14 until contacted by the stripper 11 whence they are displaced in the direction of the arrow D. In a modified arrangement, the arm 6 is displaced horizontally until the discs 1 and 2 are coaxially disposed, the discs being then rotated in opposite directions. Instead of rotatable discs, the entrainment members may consist of spaced belts or bands.

Title: Process and device for the continuous stretching of continuous synthetic filaments
IPC: D02J1/22
Filed: 1965-12-31
Abstract: 1,088,540. Stretching apparatus. G. FLEISSNER, H. FLEISSNER and H. FLEISSNER, [trading as ANSTALT FUER PATENTDIENST]. Dec. 31, 1965 [Jan. 29, 1965], No. 55324/65. Heading B5B. A process for the continuous stretching of continuous synthetic filaments at an elevated temperature, wherein the filaments are passed through a liquid bath in order to improve their stretching properties, in which process the filaments of the material to be stretched are heated to the stretching temperature in the liquid bath and are thereafter stretched in the liquid after having passed a holding unit disposed at a region intermediate the ends of the bath. Such a process may be carried out with step-wise stretching, in which process the filaments are pre-stretched in the heating-up zone of the liquid bath and in which they are stretched by a multiple of the pre-stretching amount in the stretching zone proper of the bath. Apparatus as shown comprises a troughshaped liquid container 2 with preferably one guide roller each at the intake and the delivery ends of the container (3, 4) and a holding unit each in front of the intake and behind the delivery end of the liquid container, (1, 6) in which device at least one further holping unit 5 which sub-divides the treatment zone is arranged in the liquie container intermediate the intake and delivery ends thereof. Said intermediate holding unit may be adapted to act as a squeezing unit, and the drive thereof is preferably infinitely adjustable and independent of the holding units at the intake and the delivery ends. As shown, the intermediate holding unit of the liquid container may consist of two outer stationary guide rollers 11, 12 and a centre roller 15 which is supported in a slide guide and forced against the guide rollers. Preferably, only the guide rollers of the intermediate holding unit are connected with the drive. The liquid in the bath may be inert to the filaments being treated e.g. water, or may be a swelling agent therefor. A housing 8 with a sucking-off device 9 serves to remove gases and vapours.

Filed: 1967-12-05
Abstract: 1,202,415. Rolled web dispensers. HARCRAFT Ltd. 5 Dec., 1968 [5 Dec., 1967], No. 55354/67. Heading A4G. A rolled web, e.g. paper towels, dispenser has roll 7, Fig. 7, supported in a top casing cover 4 hinged at 6 and the web entrained around a cover roller L Fig. 3, roller K, feed roll A and between feed roll and guide M hinged at J toward a dispense opening beneath hinged front plate 3 with a cutter at its lower edge. The end of roll A carries an eccentric roller C and an axially mounted cam D having a little lost motion taken up by spring SD, roller C normally locking into a notch at the top end of casing-pivoted crank E spring-loaded anti-clockwise at S.E and with casing- pivoted cam lever F spring-loaded at SF pressing down on the roller. On swinging plate 3 inwards a rubber 13, on the end of lever 12 hinged on plate 3 and spring-loaded at S12, presses on and rotates roll A clockwise to lift roller C out of its notch and allow spring SE to shift crank E anti-clockwise whereby lever F forces roller C down the inside of crank E and partly rotates roll A to project a portion of web W below plate 3, as in Fig S. The user now pulls the web and rotates roll A whereby roller C snaps over the lower end of crank E and then begins to lift lever F. Finally cam D acts on the lower end and as roller C repositions into its notch after one revolution, cam D snaps over the lower end due to its lost motion. To reload, cover 7 is hinged forwardly, Fig. 7, crank KA, NA swung upwards about pivot S carrying roller K away from roller L, and via cam roller N2 guide M is moved away from feed roll A whereby web from a new roll 7 is threaded through the dispenser. In another embodiment, a spring-loaded sliding plate replaces crank E and roll A is provided with a pawl and ratchet.

Abstract: 1,207,819. Spindles. MASCHINENFABRIK RIETER A.G. 13 Dec., 1967 [13 Dec., 1966], No. 56547/67. Heading D1J. [Also in Division F2] An expansible mandrel for mounting a bobbin sleeve 27 comprises a cylinder 4 rotably mounted on a fixed shaft 1, a braking mechanism mounted within the cylinder 4 for arresting rotation of the cylinder, a chuck mechanism mounted on the cylinder for releasably gripping a bobbin sleeve 27 and a means to actuate the braking and chuck mechanisms in sequence whereby the cylinder is arrested before the chuck is actuated. As shown, drum-driven bobbin sleeve 27 is mounted on cylinder 4 by an expanding chuck mechanism comprising axially sliding tubes 22, 24 and rubber ring 25. The ring 25 normally frictionally engages the sleeve 27 since spring 21 forces end plate 34 to the left. The brake comprises a fluid pressureactuated brake lining 10 which can be urged against ring 5 mounted internally in the cylinder 4. Brake lining 10 is mounted on a bushing 8, 9 which is fixed to one end of spring 7. The other end of this spring is attached to fixed shaft 1 so that when the brake lining 10 is urged against the ring 5 during braking it is rotated slightly against the torque of the spring. When the bobbin is to be stopped (e.g. when it is lifted away from its driving drum) pressure fluid is automatically passed through bore 2 via large port 15 to actuate the brake. A smaller port 17 is exposed to chamber 14' when bushing 8, 9 is rotated during braking and the fluid pressure acts on piston 20 so as to cause the chuck to release the sleeve.

Abstract: 1,150,049. Vehicle lighting systems. ROBERT BOSCH G.m.b.H. 14 Dec., 1967 [15 Dec., 1966], No. 56808/67. Heading H2H. A vehicle electrical system comprising head lamps, tail lamps, fog lamps and a fog tail lamp includes means whereby illumination of the fog lamps is prevented when the head lamps are on main beam. With a main lighting switch 17 in the parking light position I or driving light position II and a dip switch 18 in the dipped position 28, closure of a fog light switch 20 energizes a fog tail lamp 13-and indicating lamp 21-and also energizes relay 22 thus closing contact 36, 37 to energize the fog lamps 11. The energization of relay 22 is effected by way of lead 41, contacts 42, 43 of a relay 44, contact 29 of the dip switch 18, lead 31 and the head lamp main beam filaments 14, the current flow, however, being of a value which does not cause the head lamps to be illuminated and the relay 44 is not energized sufficiently to open contacts 42, 43. If, with the main lighting switch 17 in the driving light position II, the dip switch 18 is moved to the main beam contact 29, the relay 44 becomes fully energized thereby opening contacts 42, 43 to de-energize relay 22, the contacts 36, 37 then opening to break the circuit to the fog lamps 11, the fog tail lamp 13 remaining energized.

Each light detector is coupled to an intersection of the conductor arrays by a light guide 52. An A.C. potential is applied across the conductor arrays and a pattern projected on to the panel which produces discharges at the illuminated intersections. These remain when the illumination is removed due to a charge storage effect. The pattern is erased by irradiating with I.R. light which increases the resistivity of the p.c. material. The effect of the illumination may be supplemented by an additional write-in pulse from a source 60 which can also provide an erase pulse of suitable phase to the whole panel or sequentially to columns or intersections. This also allows selected portions of the display to be highlighted. The read out device may comprise a camera movable to allow direct viewing. Read out may be obtained using a line scan or random access system 58.
