Title: Improvements in or relating to spinning or like machines
IPC: D01H17/02
Filed: 1961-07-19
Abstract: 939,628. Spinning yarns. BRACKER A.G. July 19, 1961 [July 19, 1960], No. 26128/61. Class 120 (3). Manually-operated apparatus for separating a single traveller from a stack, applying it to the traveller ring of a spinning or like machine and simultaneously drawing the thread therethrough, comprises a tongue which thrusts the traveller on to the ring and a handle connected to a relatively displaceable fork member which carries a stop for initially entrapping the thread and thread catcher mechanism operated by a trigger member also displaceable relative to the handle. In the operation of the tool shown in Figs. 1, 2, 6 and 7, the thread 37 is caught in an aligning guide 38 and subsequently a lever 34 is pivoted by actuation of a trigger 35, Fig. 1, which retracts a slide block 32 coacting therewith, or a finger-plate 36, Fig. 7, and through a pin 39 causes a lever 29 to pivot about its support 28 so that a hook 30 seizes thread 37 and pulls it beyond the end 8b of a slide bar 8 and places it in a recess 40. The tool is then moved by a handle 1 towards the ring 12 so that a fork member 4 comes to rest firmly against the ring by means of a recess 41, and during this movement the foremost traveller 42 of a spring-loaded, automatically fed stack on the bar 8 is positioned with its legs over the flange of the ring and embracing the thread 37. The handle is further advanced against pressure of a spring 5 to cause a swivelling, spring-loaded tongue 22 to engage the traveller through a stop face 23 and separate it from the stack so that it may be clipped on to the ring, by means of the stop face, with thread 37 drawn therethrough. The tool is removed from the ring 12 and the trigger released to allow the thread to assume its normal path. In the operation of another embodiment, Figs. 8 and 10, the thread 37 is caught in the guide 38 and trigger 35 is actuated to move a spring-biased slide block 32 so that a fixed pin 42 secured to a pawl lever 43 drops into a recess 47 and locks block 32 with member 4 and also to cause hook 30 to pull the thread 37 beyond the end of bar 8. The tool is moved towards the ring 12 so that tongue 22 operates as before, although the block 32 and with it the lever 29 remains in locked position. When the traveller is in position on the ring, the tool is lifted therefrom, the thread slipping out of the guide 38 and hook 30, and the lever 43 (projecting into the trigger guard 47) is pushed back to release the block 32 and restore the mechanism to the starting position.

Title: Input oscillators
IPC: H04N9/896
Filed: 1974-06-13
Abstract: 1486444 Television systems QUANTEL Ltd 23 May 1975 [13 June 1974] 26214/74 Heading H4F An oscillator, particularly for generating clock pulses which control the writing into a retiming circuit store of samples of a television signal received from a video tape recorder, is stopped restarted at the beginning of each video line. It includes an oscillatory circuit 10, 11 which is started and stopped at instants dependent upon both the line sync and a zero-crossing transition in the colour burst. The oscillator has a monostable 31 which is triggered by the line sync pulse and whose output control the oscillating circuit. If the end of the astable period of the monostable occurs undesirably near a zero-crossing in the colour burst during one line the period is extended or shortened prior to the next line. A band pass filter 25 passes the colour burst to a zero-crossing transition detector 29 which emits a pulse at each transition. At about the centre of the colour burst monostable 31 resets, and in response a unit 41 generates a very short pulse. If unit 40 detects a negative-going transition during this short pulse it alters the monostable period from 8 Ásec. to 8À15 Ásec. or vice versa, i.e. by about a half cycle of colour burst, so that resetting of the monostable occurs about midway between successive negative-going transitions in the next line. A bi-stable 30 is set when monostable 31 resets and is reset when the next transition occurs. When it resets it sets a bi-stable 45 which stops the oscillatory circuit. Bi-stable 45 is reset via delay 44 after about 750 Ásec. to restart the oscillatory circuit. Should a line sync pulse or burst transition fail to appear, e.g. due to tape drop-out, the oscillatory circuit is not stopped and restarted at the beginning of the line, but continues operating until the next line sync pulse occurs.

Abstract: 518,934. Projectile fuzes. MEFINA SOC. ANON. Sept. 8, 1938. No. 26249. Convention date, Sept. 8, 1937. [Class 9 (i)] Relates to percussion fuzes for hand grenades having firing elements 10, 12 spring pressed towards each other and held apart by a body such as a ball 16 displaceable on impact. According to the invention, the percussion fuze is combined with a known form of clockwork time fuze 31' and a locking member, such as a sleeve 20, is also provided which retains the ball 16 by arms 19 and the clockwork by arm 21 but which is operated at the time of throwing, as by a rotary cap 24 on the exterior of the grenade, to release the percussive and clockwork elements. The clockwork fuze is of the type, such as that described in Specification 508,912, in which a disk 35 is provided with openings for the passage of the striker released after a predetermined time from the throw and finally shut off after a further predetermined time, the firing by impact being only possible during the interval. In the form shown, the firing pin 10 is carried by a hollow body 13 pressed by a spring 11 away from a fixed abutment 14 on which the ball rests at 18, the part 17 of the body being surfaced to support the ball at the top and prevent firing except when the ball is displaced by impact. The outside control 24 is connected with a thumb lever' 25 and can be rotated to move. spring stops 23 into various positions with relation to shaped grooves 26 in the sleeve 20 to render the fuze safe for transport or to effect arming. The sleeve 20 is pressed downwardly by a spring 22 and is retained by the stop 23 in the position 'shown in Fig. 2. By rotating the cap 24, the stop is moved to any of the positions shown in dotted lines. The positon 33 is a waiting position from ,whiah, by release of the thumb lever on throwing, the inclined groove x permits escape of the sleeve, or, by further rotation of the lever, the sleeve is raised to allow the stop to spring beneath a safety retaining member 27. Rotation of the cap 24 in the reverse direction will then serve to rearm the fuze.
