Abstract: 649,251. Shuttleless smallware looms. TALON, Inc. April 15, 1947, No. 9976. Convention date, Dec. 22, 1945. [Classes 142(i) and 142(ii)] In a ribbon loom, measured loops of weft are inserted by a weft needle having a straight front edge which beats up the preceding pick; the shed begins to change as the weft needle enters, and is completely changed by the time the needle is one-third of its way out of the shed. The free ends of the weft loops are knitted together by a bearded needle. Weft inserting.-The weft needle 100, Figs. 14 and 14a, has an eye 105 situated close to shoulders 103, (against which the weft thread runs) and has a straight thin front edge 104. The needle is carried by a block 106, Fig. 12, which is reciprocated in a cylinder 109 by a crank-operated connecting rod 124; the cylinder is mounted on a vertical shaft 114 which is oscillated by a cam so that the weft needle enters the shed along a curved path which brings it up to the fell, causing its edge 104 to press on the crossed warp threads and so force the preceding pick into place; the needle leaves the shed along a straight line at a slight angle to the fell. Measuring and tensioning weft, Fig. 11.- As the weft needle is being withdrawn from the shed, a cam-oscillated arm 171, pulls sufficient weft for the next pick through a tension device 150 comprising spring-loaded discs, a cam-operated rod 160 having relieved the spring loading; when the weft needle enters the shed, the arm 171 pays out the measured loop F and the full spring load is restored to the tension device to prevent weft being drawn from the supply. Shedding mechanism, Fig. 7.-Heald frames 68 are carried as described in Specification 649,318 by jacks 50, each actuated by a cam 37 through a lever 33 having a toothed extremity engaging rack teeth on the jack. To obtain a minimum front-to-rear dimension of the shedding mechanism, the jacks slide on one another, the cams 37 being disposed on four shafts and staggered to provide clearance for the levers 33. Guiding warp, Fig. 5-Before reaching the heddles, the warp passes through a reed 80. Breast beam, Fig. 5.-The edge of the ribbon at which the selvedge knitting operates is held in contact with a breast beam 200 by a wire 207; or a holding-down plate, the full width of the ribbon, may be used. Take-up motion, Fig. 5.-The ribbon is drawn forward by nip rollers 254, 257 which. are geared together and driven by change wheels. The roller 254 is carried by a spring-loaded arm 263 resting against an adjustable stop.

Title: Means for controlling electric engine-starting motors
Inventor: READ VICTOR JOHN
IPC: H02J9/08
Filed: 1958-03-28
Abstract: 849,245. Starting prime-movers. C.A.V. Ltd. March 26, 1959 [March 28, 1958], No. 29987/58. Class 38 (4). An engine is started by an electric motor n when a switch f is closed to charge a capacitor i, the current in a relay winding e being sufficient to close contacts g and so cause a motor switch h, d to close. The initial value of the motor current in relay winding a is sufficient to hold contacts g closed for a period allowing a normal starting action of the motor. If this action is successful, the acceleration of the motor is accompanied by a fall of current in the winding a so that contacts g re-open to disconnect the motor switch. If the starting operation fails, the switch f is opened to make a second attempt. The capacitor i then discharges through a resistor m whereby a time delay occurs before, on re-closing the switch f, sufficient current passes through winding e to re-close contacts g.

Abstract: In the case of an optical pick-up for CD players, the track error signal TE is, for example, obtained from the difference between two photoelectric voltages ES and FS. If, for example due to mechanical impact on the CD player, the light beam jumps from the data track to be picked up, it can be directed back onto the correct data track by means of information contained in the subcode, which however impairs the sound reproduction. In the case of unformatted optical recording media, however, this possibility of correction does not exist. 
<??>In order to direct a laser beam (8) which has jumped from the data track to be picked up back to this data track accurately and quickly, it is established by means of a direction logic (5) and a forward- backward counter (6) by how many tracks the light beam (8) has deviated to the right or left from the data track to be picked up. The correction signal for the tracking control circuit is obtained from the counter reading.

Title: Steel ingot making method
Inventor: MABUCHI HIDESATO
IPC: B22D7/06
Filed: 1980-01-09
Abstract: PURPOSE: To obtain a steel with less surface flaws and of good weldability and raise the yield rate, by specifying the distance between a mold and charging outlet holes prepared in a surface plate and the inclination of tapered wall surface inside the mold by setting a borderline depending on a certain specific value on weight of a steel ingot to be cast.  
     CONSTITUTION: In case when a steel ingot of ≥20t in weight is case, the distance C between a mold 1 and charging outlet holes 3, in molding board 2 is to be ≥ 350mm and the inclination of tapered wall surface inside the mold is to be ≥20mm/m, namely the distance of B should be more than 20mm per A=1m. In case when a steel ingot of ≤20t in weight is cast, the distance C is to be ≤350mm and the inclination of the mold is to be <20mm/m. In case of making an ingot of not ≥20t in weight, if C<350mm, the quality of the ingot will likely be deteriorated by its loose structure as well as segregation and if B<20mm/m, the intervening materials will be greatly increased in the surfacing layer of the ingot. In case of making an ingot of ≤20t, if C≥350mm, the intervening material in the surfacing layer will likely be causing the defect on ingot and if B≥20mm/m, big fish tail is generated at a time of blooming.
