Abstract: 1297924 Integrated circuits; electric component assemblies ENERGY CONVERSION DEVICES Inc 28 Nov 1969 [29 Nov 1968] 58387/69 Headings H1K and H1R Elements of an integrated circuit formed on or in the surface of a substrate are interconnected by first depositing a layer of material, capable of being changed from an amorphous high resistance condition to a more ordered conductive condition and back again by suitable applica tions of heat, to span all points to be connected, and then locally applying heat as by a laser or electron beam to effect the conversion to form conductive tracks. 1 millisecond pulses from a laser will effect the conversion while pulses of nanosecond duration produce the reverse change. Suitable materials are Ge 15 As 15 Se 10 , Te 85 Ge 15  with traces of oxygen and/or sulphur and the materials specified for use in the switching devices described in Specifications 1,070,411 and 1,070,412. Normally the individual components are probe-tested before the material is deposited and the information stored in a computer which subsequently controls the movement of a laser beam. Should a component fail subsequently, its connections may be erased and a spare component connected in its place. The method is described as applied to passivated circuits comprising a number of transistors with a common collector to a transistor resistor logic circuit, and to the interconnection of resistors deposited on an insulating substrate.

Abstract: 1313756 Sorting objects NATIONAL RESEARCH DEVELOPMENT CORP 14 May 1970 [16 May 1969] 25047/69 Heading B2H [Asol in Division G1] Potatoes are separated from a mixture of stones, clods of earth &c. by a process involving directing the mixture of objects down a chute 19 (Fig. 2) onto a horizontal deck of rotating waisted spool rollers 11 (see Fig. 3 also) which allow articles below a predetermined size to fall through the gaps between the rollers 11 onto a conveyor belt 31, where they pass along and drop off into a guide 34 that directs them onto a further deck of smaller rotating waisted rollers 21 as shewn, thereby grading the object into two sizes. The potatoes are sorted out from the other objects by means of a number of photoelectrically operated flaps 45 pivoted at 46, and which only allow potatoes to pass down them (position 45B). The potatoes are detected by a number of radio-isotope sources 40 and detectors 41 arranged so that radiation beans pass through gaps in the last pair of rollers as shewn; said gaps in the last pair of rollers being smaller than the previous gaps. Then a stone or clod of earth is detected (by virtue of it having a different radiation transparency), an hydraulic ram 48 is actuated to raise the ramp to position 45A so that the stone &c. will drop off the end of the deck. The ramp is not lowered back into position 45B until a signal is received that the stone has dropped off the roller; said signal could be provided photoelectrically by having the sone interrupt a light ray striking a photocell, but Fig. 2 shews a micro switch which is controlled by a cam 56 secured to a pivoted feeler 57 provided with a spring 58 to return it to the horizontal position shewn in Fig. 2.

Abstract: 1317241 Bobbin drive speed control D W ARCHIBALD 22 June 1970 [21 March 1969] 14845/69 Heading DID A speed control device for bobbin drives comprises indexing means such as a ratchet and pawl, which moves a set distance after each, or every n th traverse of the bobbin. The indexing means drives a cam 16 whose profile moves a first push rod 10 supported in bearings 12 and 14 which can be moved sideways to set the initial position. The movement of rod 10 is communicated to a second push rod 20 by a centrally pivoted lever 22. The rods 10 and 20 pass through slots in the lever and engage it by knife edge abutments 26 and 28, and 30 and 32. The rod 20 operates a multi-speed gearbox 18 in the bobbin drive system. Switches 36 and 38, operated by an abutment 34 on rod 20, activate a solenoid to disengage the ratchet and pawl allowing the cam 16 to rotate freely. A spring 40 allows the lever 22 to go beyond the limit of motion of push rod 20. Lever 22 is pivoted on a bearing block 24 whose position is adjustable. The device may alternatively comprise a rotary potentiometer driven by the ratchet and pawl and connected in series with a d.c. motor which drives the bobbin.

Title: Process for the production of crimped filaments and products  obtained therefrom
IPC: D06M10/00
Filed: 1971-06-30
Abstract: 1327842 Film fibrillation TEXTILKOMBINAT COTTBUS VEB 30 June 1971 30650/71 Heading B5B [Also in Division D1] Crimped filaments are made by film fibrillation, and textured yarns and fabrics therefrom, by taking a film 1 of a synthetic organic thermoplastic material which has been longitudinally stretched to an extent necessary to induce incipient fibrillation, exposing it to high-energy radiation 6, (especially electron radiation) fibrillating it 8, twisting it 9 to form a yarn or working it up to form a fabric and then subjecting the yarn or fabric to a shrinkage treatment 10 in order to develop the latent crimping of the filaments and hence to produce shrinkage and texturing of the yarn or of the fabric.  The film used may be a polyolefin, especially polyethylene, and may be subjected to non- uniform irradiation so that the extent of induced reactions varies in different areas of the film. A monomeric substance may be grafted on, to a  varying degree, over the surface of the film. The shrinkage treatment may be such that the yarn is heated up to the region of the softening point so as to cause the filaments to adhere.  In Example 1 the energy of the electrons is such that their maximum penetration into the  polyethylene film treated corresponds to precisely half the thickness of the film so that the film is only cross-linked on the side facing the  scanner 3 of the electron accelerator 4. Shrinkage is effected at 10 by hot air, whereupon the cross-linked parts of the fibres shrink to a greater degree than the untreated parts, resulting in crimping of the filaments, which are then wound up on bobbin 12. Example 2 is similar, except that the apparatus of Fig. 2 (not shown) provides for the initiation of graft polymerization of acrylic acid on to the film in vessel (13) following the irradiation step, resulting in the production of crimped filaments of locally enhanced dyeability. Example 3 differs from Example 1 in that the apparatus of Fig. 3 (not shown) provides for the film to be irradiated homogeneously, varying modification over the surface of the film being obtained by blowing the film (1), before, during and after irradiation, from below with a stream of cooling gas (14) and from above with a stream of hot gas (15); thus a different type of structure is formed on either side of the film.

Abstract: 1331221 Aerials ELLIOTT BROS (LONDON) Ltd 15 Jan 1969 [2 Jan 1968] 274/68 Heading H4A In an antenna system, the paraboloid concave collimating reflector, 10, receives energy from the feed, 14, after reflection from the hyperboloid reflector, 16. The feed, 14, is located on the axis, 17, of the hyperboloid, the letter having one of its focii coinciding with the feed and its other focus coinciding with the focus, 18 of the paraboloid reflector. Field distortion is eliminated so as to reduce "bore-sight jitter" and "frequency sensitive squirt". The former causes the beam axis to be dependent upon the polarization of the received energy when the aerial feeder system is designed to receive plane polarized energy while the "frequency sensitive squirt" causes the beam axis to be dependent upon the frequency of operation when aerial is designed to receive circular polarization.

The object is to ensure uniform quality of ground material. The coefficientvaries with the force N between the material and the grinder and its value is obtained by dividing the force F tangential to the grinder by the value N. The value F is obtained by measuring the current to a grinder drive motor 12, if electric, or its torque if hydraulic. N is measured by a load cell 17. Division is made at 18 and the result compared with a desired value 20; the resulting error signal controls the firing of thyristors 15 in the feed motor 13 circuit, or regulates a hydraulic feed motor. In Fig.2 (not shown) two feed channels are provided arranged at an angle to the horizontal and N and F are derived from measurements of their horizontal and vertical components to regulate each feed independently.
