Abstract: 1,269,666. Magnetic recording; driving heads. 28 April, 1969 [30 April, 1968], No. 21650/69. Heading G5R. In a magnetic recording and reproducing system in which a pair of heads are driven alternately and intermittently by respective feedscrews to scan closed tracks on a recording medium, head drive reversal is initiated when detectors sense the axial limits of head travel  and the angular positions of the feedscrews. As shown, a double-sided disc 11 is driven 12 in synchronism with a video signal to be recorded whilst the heads 15, 16 are driven by stepping motors 18, 21 such that head 15 records one track then is advanced two pitches while head 16 records another track above the first. When head 15 reaches its innermost position, lamp 31 and photo-cell 26 register through opening 27 in plate 24 at the same time as lamp 39 and photocell 37 register through opening 33 in a disc 35 attached to the feedscrew 19. An AND-gate (Fig. 3, not shown) is thus operated to advance both heads one pitch, then to reverse head drive so that head 16 leads and both heads scan tracks interlaced with the first. The heads are switched by pulses derived from a tone wheel 13, and erase heads (48, 49, Fig. 2, not shown) are provided.

Filed: 1923-08-31
Abstract: 203,341. Lambert, G. P. Aug. 31, 1923. Boring and drilling; milling. - In a vertical-spindle milling or boring machine the work is accurately positioned in relation to the tool spindle by making measurements between an abutment, permanently fixed relatively to the tool-spindle, and abutments fixed relatively to the work. Work-holders; gauging-devices; jigs. - The work 43, Fig. 3, is supported by clamps 52, 56, 57 on a holder 36 which is secured to a horizontal table on the machine having longitudinal and transverse feeds operated by hand. Ribs 38. 39 on the holder carry rules 40, 41 adjustably held by screws 42 either perpendicularly to each other or at some other angle. The rules are adjusted by means of gauge-blocks and plugs 44 inserted into conical holes in the ribs, the front and rear edges of the rules being preferably parallel. The work-table is set by placing gauge-blocks of the requisite thickness between the rules and a cylindrical surface 33 on a bracket 30 secured to the spindle-head, a hole 32 coaxial with the surface 33 being provided to admit ':he. spindle. In a drilling-machine, a guide-bush may be inserted in the hole 32. Bolts 47 carried bv flexible ribs 55 on the holder serve to position the. work. The rules may be integral so as to form a square. In order to ensure equal pressures always being applied to the gauge-blocks friction clutches may be provided between the handles and corresponding traversing-screws of the table. In the modification shown in Figs. 6 and 9, the bracket 30 has two mutually perpendicular measuring surfaces 68, 69, and the hole 32 is surrounded by a coaxial boss 72 which serves for adjusting the bracket. A pointer 70, pivoted to a plate attached to the spindle 71, is made to contact with the boss, and on the spindle being rotated through one revolution indicates whether the hole 32 is roaxial with the spindle. The work 43 and the rules, one of which is shown at 74. in Fig. 9, are clamped directly to the table, a second set of rules 78 serving as a standard of adjustment. In operation, gauge-blocks are placed between the rules and between the inner rules and the bracket 30 and are secured by clamps 85, 86 which enter holes 87 in the bracket. The work is then placed against the ruler 74 with interposed gauge-blocks of a thickness to bring the desired part of the work under the tool-spindle and the rules and work secured to the table and the clamps removed. Should the rules 74 become displaced, they may be set against the rules 78, a pivoted indicator 88 being used for testing any movement. Milling-machines.-The spindle 1, Fig. 1. is mounted in a rack-sleeve 3 carried by a head 2 vertically adjustable by a screw and hand-wheel 5. the driving pulley 12 being slidably keyed to the spindle. The knee 15 carrying the work-table is vertically adjustable by a screw 28 worm driven from a handle 27.

Abstract: 1,060,689. Finishing fabrics; textile treatment apparatus. Y. ONISHI. May 28, 1964 [May 28,1963], No. 22178/64. Headings D1L and DIS. A fabric a comprising thermoplastic manmade filamentary material is heat-treated by passing the fabric a through a first heat-treatment chamber 1, which is provided with tentertype conveying means (not shown), adjusting the longitudinal tension exerted on the fabric a after it has passed through the chamber 1 to compensate for the tendency of the fabric to neck, i.e. shrink transversely, subjecting the fabric to a scutching operation to obtain a fabric of desired width and thereafter passing the fabric a through a second heat-treatment chamber 5, which is provided with roller-type conveying means 6, to heat-set the fabric. In the chamber 1, air is heated by a heater 9, such as a gas burner, circulated by a fan 8, directed against the fabric a by upper and lower nozzles 15 and escapes through an exhaust pipe 10. Immediately outside the chamber the tension of the fabric a is adjusted by a necking compensator 3 and it is beaten to the desired width by a scutching machine 4. Air is heated by a heater 12, circulated by a fan 11, directed against the fabric by nozzles 25 and escapes through an exhaust pipe 13 in the chamber 5. At the exit of the chamber 5 the heat-set fabric is rapidly cooled by water cooled rollers 7 and then passes to a layering device 14. The fabric may comprise manmade filaments alone or a mixture thereof with other material, e.g. hemp or cotton. The compensator (3), Fig. 3 (not shown), comprises two fixed rolls (16) and roll (17) attached to an endless chain (18) running around wheels (19) and carrying an adjustable weight (20). If the tension of the fabric increases or decreases the roll (17) moves upwardly or downwardly, respectively. The machine (4), Fig. 4 (not shown), comprises a rubber tube (24) mounted on a number of resin bobbins (22) rotatably mounted on a fixed arcuate shaft (21).

Title: Improvements in driving-mechanism for model aeroplanes and mechanical toys

Filed: 1931-08-06
Abstract: 385,012. Spring mechanism. MILLER, D., 8, Wellesley Villas, Ashford, Kent. Aug. 6, 1931, No. 22276. [Class 10.] A driving mechanism for model aeroplanes and mechanical toys comprises a helically wound, stressed member, and means associated therewith and arranged to be displaced by the slackening in tension in said member, consequent upon its running down, to set into operation another stressed member for driving the same driven member. The invention is shown as applied to a model aeroplane driven by two sets 1, 2 of twisted rubber strands, the upper of which comes into operation when the lower has unwound. The propeller is freely mounted on a shaft B, and is driven by the lower set of bands through a pin coupling A until this coupling is broken by the sliding of the shaft under the action of a spring G, this sliding being permitted by the elongation of the strands as they unwind. The shaft L of the upper set of strands is meanwhile locked by the abutment of a key K thereon with a sleeve C, a downwardly extending arm on which co-operates with a collar on the lower shaft B to cause the sleeve to partake of the sliding motion of that shaft. Simultaneously with the disabling of the coupling A, the sleeve releases the upper shaft L and renders a pin coupling F effective to connect the shaft to the propeller through a pinion D meshing with a gear E rigid with the propeller.

[Class 39 (i).] In a device in which electrons produced between a cold cathode 1 and a discharge anode 2, pass through a control grid 4 to an amplification anode 6, the amplification anode is surrounded at a small distance by a gauze 7 or the equivalent, which is neither the cathode, nor the discharge anode, nor the control grid ; and is placed between the amplification anode and the control grid. The anode 6 is backed by a mica sheet 5, and the gauze 7 is spaced from the anode 6 by mica frames 8 which may be extended at right angles to shield the anode support and prevent arcing. The potential of the gauze is nearly equal to that of the discharge anode 2. The anode 6 is effectively " surrounded " when its arrangement is such that electrons cannot reach the anode except by passing through the gauze. The distance between the gauze 7 and the anode 6 must be so small that very little ionization is produced in the space between them ; it may be 0.25 millimeter, and the width of the holes in the mesh may be one-half that distance. The filling is neon at a pressure of 6 millimeters.
