Title: Zig zag cam selecting device in a zig zag sewing machine
IPC: D05B3/02
Filed: 1970-12-23
Abstract: 1339720 Zigzag sewing machines JANOME SEWING MACHINE CO Ltd 23 Dec 1970 [26 Dec 1969 (2)] 61283/70 Heading DIG A cam follower 11 is located positively relative to a selected one of a stack of needle vibration control cams 7 by engagement of a pin 40, on an arm 39 by which the follower 11 is movable axially of its support shaft 8, with a toothed rack 35 which is swingable (about a pivot shaft 34) to release the pin 40 when the follewer 11 is to be moved to a different cam 7. As shown the cam stack is rotatable on a vertical support 3 from the machine shaft through gear pairs 59/4 and 5/6 and the needle bar support is rocked from the selected cam through the follower 11, a frame 9 which is pivoted on the support shaft 8, by engagement by a recess 41 of the follower 11 with a vertical rod 13 mounted on the frame 9, through a member 12 which is pivoted about a horizontal pin 17 by a roller 44 which engages an edge 42 of a plate 76 secured to the frame 9, and through a link 19 with a pin 20 engaging an arcuate slot 18 in the member 12. The needle vibration amplitude is varied by sliding the pin 20 in the slot 18 and the  vibration field is changed by pivoting of a block 15, which carries the pivot pin 17 of the member 12, about its pivot 16 on a support frame 1 by a cam (not shown) engaged by the end 55a of a screw 55 mounted in the block 15. To select a different cam 7 a cam-shaft 22 is rotated by a knob 21a when first a cam 14 acts on a projection 45 of a plate 75 secured to the frame 9 to pivot the frame 9 and follower 11 from the cams, and a face. cam 25 acts on a projection 36 of the plate 35 to pivot the rack from the pin 40 and then a cam 23 acts on a projection 28b of an arm 28 secured to the arm 39 to pivot the arm 39 and either displace the follower downwards through a pin 40a against the force of a spring 38 or permit the spring to raise the followers and finally the cams 14 and 25 permit the follower 11 and pin 40 to engage a fresh cam 7 and the corresponding rack tooth. The pin 40 may engage a groove 72 in the follower (Fig. 9). A further cam 24 is engaged by a feed control arm 32. In a modification (Fig. 11, not shown) the cam shaft has two discs which move axially and pivot the follower and rack as the knob 21a is depressed prior to turning it.

Title: Belt conveyor
IPC: B65G15/62
Filed: 1979-10-05
Abstract: The conveyor comprises an endless belt (not shown), two spaced rollers (3, 4) over which the belt passes in operation, and an elongate trough (7).

Patent GB-2059906-A (GB)
Title: A process and apparatus for wrapping loads in stretch films
IPC: B65B53/00
Filed: 1980-09-12
Abstract: A process of wrapping a load (130) with a web of stretchable plastics film (32) by winding the web around the load includes stretching the web beyond its yield point during its passage to the load by feeding the web, e.g. by driven rollers (42, 44), at a greater speed than its feed speed at an upstream location, e.g. around driven roller (40). The film web stretched above its yield point gains significantly in modulus and ultimate strength. The higher feed speed of the web may be above, equal to or below the average surface speed of the load being wrapped as it is rotated on a turntable. A dancer roller (110) may be provided to compensate for variations in speed at which the web is drawn into the load. As the web leaves the dancer roller it may pass through a mechanism which can bunch the web into rope-like form. <IMAGE>

Title: High speed ribbon cable bus
IPC: H01R25/14
Filed: 1981-03-17
Abstract: A high speed bus structure is described which employs an ordinary flat ribbon cable 10. ECL receivers 41 are coupled to conductor pairs of the cable through resistors 32 which change the capacitive load of the ECL receivers to a resistive load. The receivers are coupled to the cable through a plurality of connectors 35a, b having spaced-apart pins. The pins in each connector engage less than all of the conductor pairs, thus a plurality of connectors are required to completely couple receivers to all the conductors in the cable. This connector arrangement substantially reduces the parasitic capacitance loading on the cable. The invented high speed bus is able to effectively function at 100 MHz with 80 feet of cable and with 16 receivers coupled to each conductor pair. <IMAGE>

Title: Apparatus and procedure for printing on round plastics tubing
Inventor: HARRISON WILLIAM JOHN
IPC: B41M1/40
Filed: 1981-11-12
Abstract: Method and apparatus for forming a printed sleeve for fitting over the end of an insulated wire in which the tube 26 is collapsed by external pressure, heated and then cooled to set the tube in a flattened condition before it is passed through a printer 39. The printed sections are then cut to length at 45 or the long length of the tube may be partially severed to allow the different sections to be removed. The apparatus typically comprises a first fluid chamber 14 containing fluid at an elevated temperature, a second chamber 12 containing cool fluid and a passage between the two chambers at a low level so that plastics tubing passing through the first chamber and thence through the second chamber has to pass through a region of high hydrostatic pressure which causes the wall of the tube to collapse. Water may be used on the fluid, but preferably a low melting point metal, such as mercury or a halogenated hydrocarbon fluid may be employed. <IMAGE>
