Seams; loop -stitching. - In a seam for knitted materials and the like, each selvage is stitched into by a thread, each loop of which, after passing through the selvage, is in turn presented to the opposite thread to form a looped seam, the loops of which do not cross one another. Each loop of the thread a, Fig. 2, is passed through a loop in the thread b and surrounds the next loop of the thread b. The selvages W, Fig. 3, are fed between presses cylinders 5. A needle 2 is passed through one selvage and through a loop in the thread a carried by a needle 1 and held by a double-sided looper 3, Fig. 6. The looper then drops the said loop and enters the loop formed in the thread b on the return of the needle 2. The material is fed forward and the needle 1 moves upwards through the loop in the thread b. The looper then releases the thread b and enters the loop thrown in the thread a in readiness for the next cycle of operations.

Title: Arrangements for ensuring continuity of colour synchronization in colour television systems
IPC: H04N9/76
Filed: 1963-08-23
Abstract: 987,628. Television. FERNSEH G.m.b.H. Aug. 23, 1963 [Aug. 29, 1962], No. 33420/63. Heading H4F. In a colour television system means are provided so that if the colour synchronizing component of a colour video signal is missing an alternative colour synchronizing signal is gated in to take its place. As shown, colour video signal 2 containing colour synchronizing component 2<SP>1</SP> is applied at terminal 1 and fed by way of preamplifier 3, adding stage 4 and output stage amplifier 5 to a colour television receiver 7. At point 14, that is at the junction of resistor 10 and winding 1<SP>11</SP> of a transformer 11 forming part of a separator stage 12, there arises the signal illustrated by waveform 15. Rectangular impulses, illustrated by waveform 18, which arise during the incidence of the colour synchronizing impulses 2<SP>1</SP>, are received at terminal 16 and applied by way of winding 11<SP>1</SP> to the grid of valve 17 causing it to become conductive and allowing the colour synchronizing impulses 2<SP>1</SP> to be fed to the bandpass filter 19 and demodulator stage 21. The demodulator 21 yields approximately rectangular video frequency impulses 22 which are applied to gating circuit 23 where they cut off valve 24. Colour synchronizing signal 27<SP>1</SP> is applied at terminal 25 and fed by way of phaseshifting device 26 to the grid of valve 24 and if the colour synchronizing component 2<SP>1</SP> is missing for any reason then pulse 22 is not produced and colour synchronizing signal 27<SP>1</SP> is applied by way of gating valve 24 to adding stage 4. If colour synchronizing component 2<SP>1</SP> is produced valve 24 is blocked to the colour synchronizing impulses 27<SP>1</SP>. Phase-shifting device 26 is adjusted, e.g. by hand, until there is no difference in phase at the output of amplifier 5 between the colour synchronizing signals 2<SP>1</SP> and 22<SP>1</SP>. To correct automatically any difference in phase between the colour synchronizing conponents 27<SP>1</SP> and 2<SP>1</SP> included in the colour video signals 27 and 2 derived from N.T.S.C. coders the colour synchronizing components are separated from the video signals in separator stages (Fig. 2, not shown) and the synchronizing component 27<SP>1</SP> is compared with the component 2<SP>1</SP> in a discriminator to develop a control signal which adjusts the phase of the sub-carrier frequency applied to the coders. As described, an additional colour video signal is applied together with colour video signal 2 by way of a cross-bar switch to a terminal such as terminal 1 of a circuit arrangement as shown in Fig. 1.

[Class 130] Mouthpiece strips 20 to be stuck to a uniformly - moving web 22 of cigarette paper are severed by a knife 14 from a web fed between rollers 2, 3. A support 9, flush with and reciprocating between fixed guides 8, 21 is mounted on a slide 10 driven through the engagement of a pin 11 with the edge or groove of a cam 13 driven by the shaft 6. The support and the guides have interengaging edges. The knife 14 is mounted on the slide and rises and falls due to the engagement of a roller 16 with a camgroove 17. A presser 19 mounted on the knife-support grips the severed strip which moves forward into contact with, and at the same speed as the paper 22 to which adhesive has been applied. A cylindrical brush 23 driven by a rack or segment first presses the forward edge of the strip against the paper, and then reverses to treat the trailing edge in a similar manner. Linkwork may replace the cam 13.

Apparatus for wet tumbling or wet burnishing metal articles comprises a drum adapted to contain the articles to be treated, the drum having a normally closed peripheral opening through which the articles can be loaded and unloaded, a hollow spindle extending axially through the drum, the spindle having at least one peripheral hole within the drum, means mounting the spindle for rotation about a substantially horizontal axis, means for rotating the spindle and drum, a container for the treating liquid disposed at a lower level than the drum, a filter disposed above the normal liquid level in the container, a pump for supplying liquid from the container through the hollow spindle to the drum, a hollow extension surrounding the spindle in spaced relationship at one end of the drum, the extension being in communication with the interior of the drum and having outlets through which liquid can escape, and a duct for receiving liquid from the outlets and directing it through the filter to the container. A drum 8 of hexagonal cross-section has one peripheral side formed by a detachable cover which can be moved to uncover an opening through which articles to be treated can be loaded into and unloaded from the drum. A hollow spindle 10 extends axially through the drum and has holes 10a within the drum. Trunnions 11 fitted in the ends of the spindle engage anti-friction bearings 12. One trunnion 11 is driven through a chain 16 by an electric motor 18 which also drives, through belt 20, a pump 21.

The pump outlet is connected by a pipe 24 and rotary sealing device 14 to a passage 13 extending through one of the trunnions 11. At one end of the drum is a hollow cylindrical extension 25 surrounding the spindle 10 in spaced relationship to provide an annular chamber communicating through holes 8a with the drum interior. The extension 25 has outlets 25a through which liquid from the drum can escape when a predetermined level has been reached therein. Beneath the extension 25 is a duct 26 communicating with a pipe 27 for directing liquid from the outlets 25a on to a filter tray 7 for return to the tank 6. A baffle 28 secured to the spindle 10 within the drum 8 ensures the required flow path. A filter extending over another container may be arranged beneath the drum so that the contents of the drum can be emptied into it and the liquid collected in the container, whence it is returned by the pumping system, or another pumping system, to the tank.
