Abstract: 1,231,416. Abrading. MONSANTO CO. 18 Sept., 1968 [18 Sept., 1967], No. 44287/68. Heading B3D. A method of mounting semi-conductor slices W on a carrier 10 comprises applying wax to the carrier, heating the wax to a slice mounting temperature, arranging the slices in a desired pattern, bringing the wax into contact with the slices, and pressing the slices on to the wax to thereby bond them to the carrier. In apparatus for carrying out the method, the carrier is in the form of a plate 10 which is heated above a heating plate 12 to soften the wax which forms a layer 11 covering the surface of the plate or only the areas which are to receive the wafers. The slices are initially supported on resilient posts 21 on a layout plate and arranged in position by a template 22 having holes 23 to locate the slices. The slices are placed on the posts by a vacuum pencil to avoid contamination. After removal of the template, the carrier plate is inverted and placed on the slices to locate the slices on the wax. Thereafter, the slices are pressed at between 1 and 50 p.s.i. in a press on to the carrier plate. The wafers may then be lapped, ground or polished.

[Also in Divisions E1 and B8] Cohesive and frable earths are stabilized using a binder such as lime, cement, asphalt or tar products which is injected into the earth by a drill head having a helical portion and having outlet apertures for the binder, the binder being injected into the earth during rotation of the drill head to retract it from the earth, and the drill head being fed upwardly with a movement which is less than the pitch of the helical portion so that the binder is mixed with the earth and the mixture is packed downwardly. The drill head 55 is mounted on a tube 18 guided for longitudinal movement in a column suspended from a mobile crane boom which also supports a platform carrying machinery for rotating the tube and moving it longitudinally, the column being hinged to the platform whereby it can be moved to any inclination relative to the earth without affecting driving of the tube 18. Pivoted cutters 61 close the apertures when the head is moved downwards but open the apertures when the head is moved upwards. The head 55 is connected to the tube 18 by a dog clutch 56 connected to a valve 64 controlling the flow of binder, the valve being automatically closed upon rotation of the head for downward movement and opened upon opposite rotation of the head, and the clutch being spring-loaded to its valve-closed position. Agitation of the earth may take place during downward movement of the head. In a second embodiment, Figs. 10 to 13 (not shown), the binder is an air transported powder and the helical portion of the head extends for a full pitch and its bottom half progressively decreases to zero breadth so that the powder which is discharged through apertures disposed above the bottom half is forced outwards by the latter. In a third embodiment, Fig. 14 (not shown), powdered binder is supplied in air-transported capsules which are broken by cutters on the inside of a supply tube. The capsules may be successively fed by a piston from a magazine through an air lock chamber having appropriately operated valves, Fig. 15 (not shown).

Abstract: 1,259,149. Making wave guides; coiling helices. CABLES DE LYON ALSACIENNE. 10 Nov., 1969 [15 Nov., 1968; 24 July, 1969; 25 July, 1969], No. 54983/69. Headings B3A and B3E]. A method for the semi-continuous production of wave guides formed of an insulated wire wound helically with contiguous turns is characterized in that each wave guide is formed by the repeated process of forming a wave guide section by means of a winding carriage on a cylindrical mandrel, the assembly formed by mandrel, the wound section and carriage being displaced longitudinally over a distance equal to the length of the section, and then immobilizing the section in this position whilst the mandrel is returned into its initial position to permit the forming of the next section thereon. Apparatus for carrying out the method comprises a mandrel 3 supported in a jaw plate 4 and a rotating tailstock 5. A winding assembly 6 comprises a carriage 7 supporting one or more reels 8 of wire 9 and wire guides 10. A carriage 11 supports one or more reels 12 of insulating or conductor tapes 13 guided by tensioning wheels 14. Pipes 15 project synthetic bonding material on the guide as it is being formed the material being heated by electric windings 16. After the guide is formed a jack 17 pushes the guide past the winding assembly 6 and the mandrel is returned by the jack to its initial position by clamping jaws 22 having an internal shoulder 24 for engaging the end of the guide while the jaws are pushed by a plate 25 attached to the piston of a jack 26 (Fig. 3). Alternatively diametrically opposed clamping shoes 27, 27<SP>1</SP> (Fig. 5, not shown) are used. In a modified winding apparatus a cage 28 is driven by a motor 29 and comprises two reels 8, 8<SP>1</SP> the wire from which is guided by wheels 30, 30<SP>1</SP> and 31, 31<SP>1</SP> one of which regulates its tension.

Abstract: 1333224 Welding by fusion V R LEPP V A VINOGRADOV K M SIBGATULIN and J N CHERKASOV 10 Nov 1970 53476/70 Heading B3R [Also in Division H5] Gas-shielded arc welding cutting or spattering processes using spaced non-consumable electrodes providing an arc gap are carried out by supplying the arc discharge current in pulses, in order to increase the heat concentration in the discharge, the current pulses having a duration not in excess of the time period during which the cross-sectional area of the arc discharge column expands and preferably not exceeding 1 millisecond. The ratio of the pulse spacing to the pulse duration for the current supplying the arc discharge is between 5 and 100. For an argon-shielded arc, using tungsten electrodes with an arc gap of 1mm., the pulse duration is 120 microseconds. The arc discharge is thus "compressed" without additional mechanical devices and components, i.e. using only the external devices supplying the discharge with power. The arc gap is cooled naturally, i.e. without forced cooling, between pulses, thereby raising heat concentration in the arc gap when the next current pulse is applied.
