Title: Tufting machines
IPC: D05C15/18
Filed: 1959-10-28
Abstract: 891,509. Sewing machines. CABIN CRAFTS Inc. Oct. 28, 1959 [June 10, 1959], No. 36559/59. Class 112 Tufting machines, embroidery. A tufting machine comprises a plurality of needles spaced from each other in the direction of fabric feed, means for reciprocating the needles to penetrate the fabric, means carrying the needles for said reciprocatory movement which means is movable to and fro while the machine is running, and only at the uppermost position of the needle reciprocating means, in the direction of fabric feed for connecting a selected needle to the reciprocating means to be reciprocated thereby, and thereby to create a design. Needle-driving mechanism, disconnecting and controlling, multiple needle machines. The needles N<SP>1</SP>, N<SP>2</SP> are secured in brackets 12 secured to the ends of needle shafts 14 slidable in a needle shifter 18 which may be moved in the direction of fabric feed by a pneumatically operated piston 22 in a cylinder 20. Elbows 15 at the ends of the needle shafts engage vertical grooves 16B in a thrust bar 16 which is reciprocated vertically by rods. Movement of the shifter to the left, as shown in Fig. 4, or to the right causes the elbow of the shaft of needle N<SP>1</SP> or N<SP>2</SP>, respectively to engage a transverse passage 17 in the thrust bar and reciprocate with the bar to form tufts in the fabric. The unengaged needle bar is maintained in its inactive position by its contact with a brake shoe mounted on a bracket 19<SP>1</SP>. The needle shifters 18 may be set at an angle of 10 degrees to the line of fabric feed so that the rear needle will not sew down the last stitch of the front needle. Each needle may be duplicated or triplicated if required. Threads controlling, otherwise than in stitchforming. The threads A, B for each pair of needles N<SP>1</SP>, N<SP>2</SP> pass over guide rollers 38A, 38B respectively, pivoted to one end of one of a series of beams 36 pivoted on a shaft 37. The other end of the beam is connected to a piston and cylinder arrangement 44 controlled by the solenoid valve 60 which also controls the piston 22 of the needle shifter 18, so that when the needle N<SP>1</SP> is selected for operation the beam is tilted clockwise by the piston of 44 and the yarn A is pressed on the surface of a rotating yarn feed roller 34 to feed the yarn to the needle N<SP>1</SP>. When the other needle is selected the beam is tilted in the opposite direction, the feeding of yarn A ceases as it moves off the roller 34 and yarn B is pressed against feed roller 32 to be fed thereby to the needle N<SP>2</SP>. The solenoids of the valves 60 are connected in series with a power source and with fingers 67 trailing on the surface of a rotating pattern drum 80. The valves are selectively operated as the fingers contact electrically conductive or non- conductive portions of the pattern set out on the surface of the drum.

Title: Improvements in or relating to rotary winged aircraft
IPC: B64C27/54
Filed: 1961-10-12
Abstract: 958,536. Rotary wing aircraft. K. H. WALLIS. Oct. 10, 1962 [Oct. 12, 1961], No. 36736/61. Heading B7W. The blades of an aircraft lifting rotor are mounted on flapping or teetering hinges and a plate is pivoted on a blade root or the rotor shaft, so that an edge of the plate can contact the rotor shaft or blade root, and the plate is movable about its pivot by centrifugal force to disengage its edge from the rotor shaft or blade root. The Figure shows a see-saw rotor mounted on a teetering axis (not shown) perpendicular to the axis of the blades 11 and to that of the rotor shaft 14. Plates 15 are pivoted to the blade roots at 16, and when the rotor is at rest are abutted against stops 21 by springs 18, so that a portion 23 of each plate contacts the rotor shaft and prevents teetering to avoid the rotor being fouled by an empennage or other structure. At a certain rotational speed, the centrifugal force on weights 17 rotates the plates to abut stops 22, so that a concave portion 24 of each plate is presented towards the shaft, to permit teetering. The operative edges of the plates may be so shaped that the permissible teetering increases continuously as the plates are pivoted increasingly by the centrifugal force.

Filed: 1968-08-01
Abstract: 1,236,749. Television. INTERNATIONAL STANDARD ELECTRONIC CORP. 1 Aug., 1968 [3 Aug., 1967], No. 36741/68. Heading H4F. In a television of the segmential dot interlaced raster type having a predetermined number of dots D in each time and a predetermined number of lines L in each frame, and having the dot frequency fe expressed by the equation fe=fv(L.D/n 1 .n 2 ), where fv is the frame frequency, n 1  the vertical interlace ratio, n 2  the dot interlace ratio, the quotient (LD/n 1 .n 2 ) being irreducible, the information contained in each dot is digitally encoded and transmitted as one of n 2  discrete levels. Video signals and line and frame sync. signals D, Fig. 5, are applied to a sampling gate 26, Fig. 1, and sampling pulses C are produced at a recurrence frequency fe by master clock 17 and a by-n 2  divider 24. Sampled analogue pulse signals E are applied to an analogue/digital conversion circuit 28, whereby digital encoded signals H, indicative of successive predetermined amplitudes selected from a plurality (A, B, C, D), E of such amplitudes and respectively nearest to the amplitudes of successive analogue pulse signals, are produced. The amplitudes A, B, C, D are set by tapped resistor 33 and fed into level comparator 29. Signal appears at an output 44 (A, B, C or D) if the amplitude of the analogue pulse sample E is greater than the corresponding comparison amplitude. Thus the outputs at B, C and D appear as shown at F. The outputs 44 feed to a decimal to binary converter having two outputs 45 giving 0 or 1 signals and synchronized by the clock signals. The parallel binary output is shown at G and this is converted at 32 to a serial binary n 2  bit output to give the transmitted signal as shown at H. At the receiver station, Fig. 6, the binary coded signal after separation of the sync. signals at 67 are fed to a digital/analogue converter 65 and thence to a video monitor 63. Instead of the clock operating continuously, it may be started by a pulse synchronous with the line sync. pulse, and stopped after D pulses have been produced (Fig. 8, not shown).

Abstract: 854,523. Windscreen wipers. TRICO PRODUCTS CORPORATION. Dec. 5, 1956 [Dec. 5, 1955], No. 37210/56. Addition to 828,298. Class 138(1). The spring hinge of the wiper of the parent Specification is made adjustable, a thumb adjustment being provided in the form of a disc 23 pivoted at 24 on the lever 14 and having a stepped series of seats 25 for selectively receiving the spring terminal 21. The series of seats extends about the pivot 24 on an eccentric arc so that the successive seats serve to support the terminal 21 at different elevations and thereby increase or decrease the spring stress accordingly. The seats 25 are cam-like in shape to ease the spring terminal out of one seat and into the next. In a modification, Fig. 9, the superstructure levers 1411, 15<SP>11</SP> are hinged together by a pin 17<SP>11</SP>. A tension spring 18<SP>11</SP> is anchored by a pin 19<SP>11</SP> at one end and by a connector plate 32 engaging into hook 33 in an eccentric opening 34 provided in an adjustment disc 23<SP>11</SP>, the latter being given floating support within slots 35 formed in the side flanges of the channel-sectioned lever 15<SP>11</SP>. The periphery of the disc is formed with a series of seats 25<SP>11</SP> for engaging in the adjacent end walls of the slots 35 under the urge of the spring 18<SP>11</SP>, and when adjustment is desired, the oppositely projecting portions of the disc are engaged between the thumb and forefinger and bodily withdrawn against the spring tension, then rotated, and finally released to-present another selected .pair of seats 25<SP>11</SP> to the end walls of the slots 35. This adjustment serves to rotate the eccentric opening 34 to vary the stress in the spring 18<SP>11</SP>. An additional modification is that pressure is transmitted from the arm-attaching member to spaced points on the central part of the blade unit by means of a yoke member instead of to a single point as in the wiper of the parent Specification. Specifications 702,849, 702,899 and 702,900 also are referred to.
