Title: Sewing machine starting thread control mechanism
IPC: D05B57/26
Filed: 1962-08-08
Abstract: 949,430. Sewing machines. SINGER CO. Aug. 8,1962 [Aug.24, 1961], No. 30368/62. Heading D1G. The single-thread lock stitch cyclicallyoperated sewing machine described in Specification 906,397, in which the machine stops in a predetermined position, the upper and lower threads are severed adjacent the work when the machine stops, and in which the looptaker bobbin is wound in situ by the needle thread being clamped against the looptaker beak while the bobbin is rotated with the looptaker, the free length of thread extending from the needle being drawn into and wound around the bobbin at the end of the winding operation, is modified to provide for positioning of the thread takeup in a selected one of a range of positions when the machine stops in order to ensure that the free length of thread is sufficiently short to be drawn wholly within the bobbin. The thread take-up lever 30, pivoted at 31 and connected by a link 29 to a crank 25 driven by the machine arm shaft 17, draws up a loop of needle thread between fixed guides 33 and 34. The machine is so arranged that, when at rest, the take-up will occupy a dotted line position lower than its highest position, shown in full lines, whereby, during its succeeding oscillation, the take up will withdraw thread from the needle to shorten the free length extending from the latter. The stop-motion mechanism comprises a frame 64 pivoted at 65 about an axis perpendicular to the vertical plane through the axis of shaft 17. When frame 64 is swung, against spring bias, in the starting direction, an arm 63 thereon shifts the loose half of a driving pulley towards the half comprising a hub 68 rigid with shaft 17. An arm 66 slidable on shaft 17 is pivoted to a spindle 69 slidable in a sleeve 70 carried by frame 64. Flexible washers 71 and 72 are arranged respectively between sleeve 70 and term 66 and between sleeve 70 and lock nuts 73 on the end of spindle 69. When frame 64 is released, arm 66 moves into a notch 67 in hub 68 to stop shaft 17 in a predetermined position. Variation of said position, and hence the stationary position of take-up 30, may be effected by re-arranging the washers 71 and 72. The arrangement shown provides for the full line position of rest of arm 66. By shifting one washer 72 above the sleeve 70 the dotted line position of rest of arm 66 is obtained.

Title: Synthesis of 1-benzyl 5, 6, 7, 8,-tetrahydroisoquinoline
Filed: 1950-12-12
Abstract: 1 - Benzyl - 5 : 6 : 7 : 8 - tetrahydroisoquinoline is made as follows: 2-phenylacetylcyclohexanone is condensed with cyanacetamide and alkali metal carbonate to give 1-benzyl - 4 - cyano - 5 : 6 : 7 : 8 - tetrahydroisoquinolone-3; the latter is hydrolysed under mildly acidic conditions (e.g. heating with hydrobromic acid) whereby the cyano group is replaced by hydrogen; the product is converted into 1-benzyl-3-halogeno-5 : 6 : 7 - 8-tetrahydroisoquinoline by means of a phosphorus oxyhalide (e.g. the oxychloride); finally catalytic hydrogenation, e.g. with a palladium-charcoal catalyst, replaces the halogen by hydrogen. The product may be converted into N-methyl-morphinane by quaternation with methyl iodide, reduction to the octahydro compound and ring-closure of the latter.  An example is given of the process.  2-Phenacetyl-cyclohexanone is made from phenylacetic ester and cyclohexanone.  Specification 677,595 is referred to.
Patent GB-863333-A (GB)
Title: Percussion tool for tightening and loosening bolts and nuts
IPC: B25B23/145
Filed: 1958-09-23
Abstract: 863,333. Screwing up and unscrewing nuts &c. PRESSLUFTWERKZEUGUND MASCHINENBAU PREMAG G.m.b.H. Sept. 23, 1958 [Sept. 24, 1957], No. 30417/58. Class 83 (3). An impact wrench comprises means for reducing its power after it has run for a predetermined time. The tool has the timing mechanism situated in the handle 1 and adjusted by a knob 6. A lever 5 reverses the direction of rotation of the tool shaft 4. In a pneumatic tool, air enters a union 101, Figs. 2 and 3, and passes to the tool motor past a ball valve 104 and through a passage 106 throttled by an adjustable screw 161. The adjustment of the screw determines the maximum force which the wrench can apply. The ball valve 104 is operated to start the tool by depressing a trigger 113. The trigger carries a latch 114 which momentarily depresses a rod 112 before slipping off and allowing the rod to spring back. The rod 112 presses down a ball valve 110 to allow air to pass through passages 101, 107, 108, 109, 121 and 122 and move a plunger 124 upwardly to open the ball valve 104. The plunger 124 is held up by air passing through a passage 126, constricted at 127, and the passage 122. Air also passes along passages 120, 129 to a chamber 130 where it commences to advance a piston 132. The piston 132 forces oil through a constriction 141 to advance a piston 142. After a predetermined travel, initially adjusted by turning a sleeve 146 carrying a pin 146a engaging a helical groove 148 in a valve member 147, the piston 142 depresses a valve 151 so that passages 153 and 158 are aligned to release the pressure in the passage 122 and so allow the ball valve 104 to close. The motor stops and the parts are returned by springs to their initial positions. In a modification, the pistons 132, 142 are replaced by an air reservoir which gradually fills. When a certain pressure is reached in the reservoir, a release valve is opened. The trigger is also replaced by a push button which is forced upwardly by air pressure after the initial depression thereof. When the tool is set for counter-clockwise rotation, the timing device is cut out, thus allowing continuous operation for unscrewing operations. In a further modification, the supply of air is cut off by a clockwork timing mechanism 322, Fig. 7. The mechanism is started by depression of the trigger 313 which also positions a valve 312 to supply air to the tool motor. When the mechanism "times out," the valve 312 is restored to its cut-off position. In a final modification, the tool is electrically driven and has an electric time switch. The timing device may be incorporated in the supply line instead of in the tool. Instead of cutting off the supply, the timing device may reduce the power supplied, for example, by providing a non-circular ball 104, Fig. 3, air may still pass to the tool motor. The timing device may stop the tool by operating a clutch.

[Also in Division D1] Glue-printing devices 14 ... 18 acting on paper or like webs 19 ... 23 are arranged one above the other and staggered against the direction of motion of the webs, and each web leaves its corresponding glue-printing device in such a way that it is the underside that is pasted: this ensures that glue falling from the webs does not reach portions of the webs which are not to be pasted. The webs are first perforated by devices 33 ... 38, similarly staggered from the vertical, and are subsequently combined over a roller 25, and tubed, after which tubular blanks are separated off at the perforations to be formed into bags. The perforations are offset to produce staggered ends to the multi-ply blanks. Guide rollers 26 ... 29 are placed so that the lengths of web between the roller 25 and the glue-printing devices are equal, and rollers 45 ... 50 can be adjusted to compensate for different extents of stretch in the webs.

Special quantities, registering.-A meter having adjustable means for actuating a signal from the time when a predetermined consumption is exceeded until the end of the recording period, as dedescribed in the parent Specification, is constructionally modified as shown. On the spindle 4 is rigidly mounted a three-armed hub 5, one arm 6 serving to drive, the maximum pointer 2. Resting on the hub 5 is a loosely-mounted cam-disc 7, which is clamped between the arm 6 and an arm 8 by a screw 10 passing through a slot 11 in the disc. A bell-crank lever 13, 14 is provided with a roller 15 engaging the cam edge of the disc 7 and having a projecting spindle 13 which normally lifts a blade spring 7<1>.
