Title: Mechanism for feeding weft-bobbins to the automatic bobbin-change mechanism of a loom
IPC: D03D45/20
Filed: 1960-06-28
Abstract: 913,944. Feeding bobbins to looms. RUTI MACHINERY WORKS Ltd. June 28, 1960 [June 29, 1959], No. 22644/60. Class 142(2). Randomly stacked bobbins 13 in an inclined magazine 14 are successively fed to the inlet 12 of an automatic bobbin change mechanism. A continuously moving conveyer peg 28 lifts a frame 21, 31 so that a bobbin held between feet 32, 33 and a hook 34 is raised to the inlet. At the top of its travel the peg 28 pivots a lever 42 allowing the hook 34 to turn against the action of a spring 43 to release the bobbin; simultaneously a roller 56 enters a cam-track 57 on the frame 31 causing a tongue 58 to turn and discharge the bobbin into the inlet 12 and a feeler 59 to leave a recess 60. With the peg 28 holding the hook 34 twisted the frame 21, 31 descends, the feeler 59 enters the recess 60 and, if no bobbin is felt, allows the roller 56 to ride on the frame 31 and descent to continue. If, however, a bobbin is felt the roller 56 cannot ride on the frame 31 which remains raised until the feeler is cleared. Upon descent of the frame the feet 32, 32 rest on the next bobbin and continued movement of the peg 28 allows the hook 34 to turn under the bobbin for lifting. A mechanism (Fig. 4, not shown), allows the frame to remain raised while the magazines 14 are changed and various mechanisms, including a magnetic one, may replace the feet 32, 32 and hook 34.

Patent GB-1106254-A (GB)
Title: Improvements in and relating to the production of nets from thermoplastic sheets or films
Inventor: PATCHELL ALBERT GEORGE
IPC: B29D28/00
Filed: 1965-05-31
Abstract: A method of forming a non-woven openwork net from a thermoplastic material comprises extruding the thermoplastic material to produce a flat film having integral loops at its longitudinal edges, embossing the flat film with a desired pattern of embossments, engaging the embossed, flat film adjacent the integral loops in two divergent guides, each guide comprising two members spaced apart by a distance slightly greater than the thickness of the embossed film, drawing the film along so that it is stressed longitudinally by draw rollers and so that the integral loops, cooperating with the divergent guides, cause simultaneous transverse stressing of the film and thus net formation, the loops being maintained in an expanded state during the transverse stressing.  Thermoplastic materials specified include polymers of olefins and copolymers thereof, ethylene and propylene polymers being preferred, especially high density polyethylene, which may be stressed at temperatures from room temperature to 100 DEG C. The apparatus of Application No. 22812/64 may be utilised, and the loops may be held in their expanded state by means selected from the group consisting of a cord, roll, hollow tube, liquid, grease and compressed gas maintained within the loops (so as to form edge beads) during the transverse of the film.  Non-woven nets may be made from films so produced.  Solid fillers, as in application No. 22812/64 may be utilised to fill the edge beads, e.g. polytetrafluoroethylene cords, and if a cutting operation is not to be performed these solid or "free-floating" fillers are introduced into the integral loops at the beginning of the stretching operation.  They are introduced into the first part of the film as it is extruded and brought to the divergent guides upon which the transverse stretching is carried out. Alternatively, mandrils anchored at the die, around which the molten material is extruded to form the loops may be extended into said loops to constitute the fillers for the transverse stretching zone. Alternatively the mandrils may have extensions of the desired length attached to them.  In either case, means may be provided for supplying air at low pressure into the interior of the loops, just after the loops have been formed, so as to hold them open while they are setting after extrusion.  When the net has been formed the loops may be cut from the longitudinal edges before the net is collected on a roller.

Title: Manufacture of semi-conductor devices
Inventor: BROWN RICHARD STANLEY
IPC: H01L23/31
Filed: 1963-06-11
Abstract: 1,027,476. Semi-conductor devices. JOSEPH LUCAS (INDUSTRIES) L t d. May 29, 1964 [June 11, 1963], No. 23167/63. Heading H1K. In the manufacture of a semiconductor device, an N-type zone covered by a layer of glass is formed in a P-type silcon wafer, the zone is diffused further into the wafer, the remainder of the surface of the wafer being simultaneously oxidized, and the glass layer is removed using a selective etchant. A plurality of diodes are produced as shown, the starting material 5 being a slice of P-type silicon. The slice is heated in phosphorus pentoxide vapour to produce an N-type surface layer 6 covered by a thin layer of phosphorus glass (not shown), step B. Boric oxide in a solvent is applied, step D, and diffused in to form a P + type layer 7 covered by a thin layer of boron glass (not shown), step E. Parts of the phosphorus glass layer are masked by spraying acid resist through apertures in a steel mask and then sintering. The unmasked portions of the glass layer are removed by etching and the exposed parts of the N-type layer are also removed by etching, step F. The slice is washed, placed in heated concentrated chromic acid, step G, washed in dionized water and placed, without drying, in a furnace through which dry oxygen is passed to produce simultaneous oxidation and diffusion, step H. Oxide layers do not form over layers 6 and 7 since these are already covered with the layers of phosphorus and boron glass which are now removed by etching in hot potassium hydroxide and sandblasting respectively. The electrode surfaces are activated using an acidified solution of palladium chloride and nickel layers 10 deposited by electroless plating, step J. Before the second electroless plating, step L, the sintered nickel layers are reactivated using 30% fluorosilicic acid or dilute hydrofluoric acid.
