Lock-stitching by rotary hooks.-In order to prevent the bobbin-thread, when it becomes slack in certain circumstances, from drooping over the flange 47, Fig. 2, of the bobbin-case carrier (which contains the notch 48 for engagement by the rotation-preventing finger) this flange is provided with an extension or a member lying close to the path of the loop-seizing beak 24 of the hook. In the form shown in Fig. 2 this guard is constituted by a circumferential lip 57; in a modification, a guard of bent wire fixed to the inner face of the flange 47 takes the place of the lip 57. Additional guiding of the bobbin-thread may be provided by a self threading eyelet member 53, Fig. 9, fixed on a recessed portion 76 of the bobbin-case and fitting in a recess in the base of the flange 47 of the bobbin-case carrier.

A spring 75 between support member 46 and the bearing biases it away from spring 24. In the embodiment shown the retainer 96 is tubular and a cap 112 is screwed to an end of the nut 88 and rotatably supports the outer sleeve 120 of a Bowden mechanism, the cable 106 being the inner member of this mechanism. Adjustment of the freeplay or for clutch wear is effected by loosening a lock-nut 90 and engaging a flange 114 of the adjusting nut with a tool to rotate the nut and adjust the spacing between release bearing and spring. In an alternative embodiment the tubular retainer 96 is replaced by a rod (134), (Fig. 2, not shown) having a bore at one end in which the end of cable 76 is crimped and a retainer nut screwed to its other end to retain the cable 106. A further embodiment has no Bowden mechanism, the outer sleeve 120 being dispensed with and the cap 112 also, the cable 106 being here connected to a retainer member screwed to a rod having cable 76 supported in a bore in its opposite end (Fig. 3, not shown). In the embodiments of Figs. 2 and 3 the rods have each a flange formed on them engaging an end of the adjusting nut (with the clutch engaged).

Abstract: 892,166. Dispensing liquids by gaseous pressures. MESHBERG, P. May 13, 1960, No. 17081/60. Class 102(2). [Also in Group XVIII] The measuring chamber 33 of a valve for dispensing a measured quantity of fluid from a pressurized container 12 is formed at the bottom with a neck 16 a and a central aperture 17 so that different sizes of auxiliary chamber 35 can be screw or press-fitted on the neck to vary the quantity dispensed. If the valve is to be used with the basic chamber 33 by itself, a cap or plug is fitted to close the aperture 17. In the inoperative position of the valve, a spring 27 presses the hollow stem 23 upwards so that a discharge passage 25 is above a resilient disc 18 and a flange 26 seals on the disc. On depressing the valve, a second resilient disc 30 seals ports 29 connecting the chamber to the container and then slides on the valve stem against the action of a spring 31 unitl the passage 25 comes below the disc 18 and allows the contents of the measuring chamber to discharge. To ensure that the contents of the auxiliary chamber are discharged, an orifice 36 is provided in the inner hollow portion of the valve stem.

[Also in Division H3] A transformer device 10 for obtaining a high voltage comprises a short cylindrical ring 11 of piezo-electric material, e.g. barium titanate or lead titanate zirconate, the inner and outer surfaces of the ring having pairs of electrodes 21, 23 and 27, 29, the electrodes of each pair being connected together. A further electrode 31 embraces the ring. The electrodes 21, 23 and 27, 29 are respectively connected to input conductors 15 and 13 and the electrode 31 is connected to an output conductor 17, these conductors also serving to support the ring 11 on an insulating base (79) (Fig. 1, not shown). In order that the ring 11 may have resonant vibration in the hoop mode with alternate expansion and contraction of the circumference, the circumference of the ring is selected to be one half of the wavelength of the exciting signal applied between the terminals 33, 35, or of a harmonic thereof. The output voltage at the terminal 37 is directly proportional to the distance between the output electrode and the input electrodes and to the Q of the ring 11. The ring may be reinforced by an outer wrapping of glass filament (41). The device 10 is intended for use with a T.V. receiver (Fig. 6, not shown), the output of the device, after rectification, giving a D.C. voltage of 20 kv. for application to the screen of the picture tube (64).

Abstract: 767,695. Coating webs. C.A.V., Ltd. June 21, 1954 [June 22, 1953], No. 17184/53. Class 140. A permeable paper strip for subsequent use in a filter-forming machine is coated with adhesive applied as a narrow layer adjacent each edge of the strip but on opposite sides of the paper and coiled on a first rotary support at a rate which causes this operation to occupy about one-half of the drying time of the adhesive, a spacer strip being intercoiled with the paper strip, the two strips being subsequently re-coiled at the same rate, on a second rotary support from which the paper is adapted to be fed to the filter-forming machine. The spacer may be supplied from a previously formed coil as it feeds the filter-forming machine. As shown, two spindles f, j are driven by electric motors n, o, and each is adapted to accommodate two reels, either of which may be clutched to the spindle, the other being free. Control means is provided so that the linear speed of the strip being wound may be maintained constant. Paper strip a is supplied from a roll b, and is guided by rollers v past adhesive applicators t, u, in such manner that adhesive is applied adjacent each edge but on opposite sides of the strip, which is then wound, e.g. on a reel 1, Which is clutched to the spindle f, the paper strip being intercoiled with a narrower spacer strip h which is unwound from the coil k, from which a paper strip is simultaneously unwound and passed to a filter-forming machine. At the same time, the previously-formed coil k<SP>1</SP> is re-coiled on the reel 2, which is clutched to the spindle j. When coiling is completed, the adhesive applicators are moved on their supporting slide s to a position opposite the empty reel on the spindle f, this reel now being coupled to the spindle and a further coil formed thereon, the paper strip being intercoiled with a spacer derived from the coil on the reel 2, as this coil is unwound to feed the filter-forming machine. Simultaneously, the coil on the reel 1 is re-coiled on the empty reel on the spindle j. Specification 767,696, [Group I], is referred to.

Abstract: 1448690 Feeding sheets in presses TRIDAN TOOL & MACHINE Inc 20 Dec 1973 17264/75 Divided out of 1448688 Heading B3W A press includes a device for feeding sheet through the press comprising a feed bar 86, Fig. 4, carrying spring loaded feed fingers 91 and slidable in the feed direction along a track such as rods 85 by means of a link 87 pivoted to an arm 82 depending from the press platen 28. The feed bar is preferably connected to the platen by an arm and a link at each end. A fixed bar 83 carries spring loaded fingers 93 for holding the sheet against retraction when, on the up stroke of the platen, the feed bar retracts. For feeding during both the up and down strokes of the platen, the fixed bar is replaced by a movable bar 35, Fig. 1, mounted similarly to the bar 86 but for movement in the opposite direction. The spring loaded fingers on bars 34, 35 engage in collared holes 29 formed in the sheet by dies 26 and have bevelled upper faces, Fig. 5 (not shown), so that while they are inoperative the sheet depresses them into their housings. A pressure plate 57 forces the sheet 22 down to enable the fingers to enter the holes. In an alternative embodiment, Fig. 6, one bar 102 is connected to the platen by an arm 101 and the other, 114, by the piston-rod 110 of a double acting air cylinder 109. With the piston-rod retracted, the feed bars 102 and 114 operate in the same way as the feed bars 34, 35. With the rod extended, a stop 115 limits downward movement of a plate 111 forming part of the linkage between the piston-rod and the feed bar and supply of air to the upper side of the piston during the up stroke of the platen will cause the feed bar to remain stationary during that stroke. A cut-off is provided at the left hand side of the press, Fig. 1.
