Title: Improvements in and relating to loom shuttles
IPC: D03J5/00
Filed: 1922-12-28
Abstract: 192,371. Boitel, A. Jan. 25, 1922, [Convention date]. Weft-inserters not carrying bobbins, looms with. -A " shuttle " to enable any loom to work as a continuous weft-feed loom has projecting beyond each end a hook 13, 14, which engages welt delivered from bobbins on each side of the loom and inserts such weft into the shed the inertia of the hooks causing one hook to project and the other to be retracted when the shuttle is struck by the picker. The " shuttle " or weft inserter itself contains no weft spool, but has movable mechanism inside comprising hooks 13, 14, the stems 10, 11 of which are connected to a spring-controlled sleeve 6 sliding on a rod 4. In operation, the shuttle 1, when in the right-hand box, on being struck by the picker moves to the left, the inertia of the hook mechanism causing the hook 14 to protrude while the hook 13 is retracted. A finger 19 on the sleeve 6 then engages with a hole in a fixed spring strip 17, thus holding the hook mechanism in the position shown in Fig. 3. The weft is then presented to the hook in any suitable manner, for example by the device shown in Fig. 6 as applied to the other side of the loom when the hook 13 protrudes. The weft thread passes from a bobbin through a fixed eye 23 and a movable eye 25 formed in a bar 26 resting on a lever 27 raised and lowered by a cam &c. The weft 22 is thus raised at the proper time for the hook 13 to engage it, and lowered into the notch 28 to allow the shuttle to pass at the beginning of its pick. The hook 14 having engaged the weft on the right-hand side moves along with the shuttle from right to left, and draws a double shoot of weft through the shed. When the shuttle arrives in the left-hand box, the lay in beating up frees the weft from the hook 14 which is on its side, while a stud fixed on the loom pushes a spring strip 17 fixed in the shuttle, out of engagement with the sliding sleeve 6, so that the spring 16 may push back the sleeve hooks to mid position ready for the next blow of the picker. Any number of weft-distribution bars may be arranged on each side of the loom and may work in determined order to allow weaving in colours. These devices may be operated by jacquard or other apparatus. Likewise any number of weft threads may be engaged at the same time by one of the hooks to produce varied effects.

Abstract: 1,187,879. Binary multiplier. STANDARD TELEPHONES & CABLES Ltd. 26 July, 1968, No. 35857/68. Heading G4A. A multiplier for binary numbers has two shift registers, each receiving one of two numbers to be multiplied together, a product store in which the product of the numbers is formed, and a carry store for temporary storage of carry digits, the registers and stores being so associated that each storage location can be considered to occupy a column containing also a storage location of the other store or stores and locations or location, number entering means for the two registers arranging the numbers so that each bit is separated from the next by a single empty storage location, the numbers read in the same sense and the least significant bit of one number lies in the same column as the most significant bit of the other number; wherein the multiplication of the two numbers is effected in a series of successive steps after each of which the numbers are shifted one location in opposite directions, each step comprising the performance of a logic operation according to Fig. 3 on all columns of the multiplier taken in pairs consisting of one column m in which the registers contain bits ai, bj and the next higher order column m+ 1, the successive steps being continued until all the digits of the two numbers have been multiplied together and the carry store Q is empty. Fig. 2 shows a portion of the multiplier containing columns 6, 7, 8 of Fig. 1a. The two numbers are stored in the A and B registers via AND gates 12 enabled by Enter line 13. The "1" outputs of each register location are connected via an AND gate 15 and an OR gate 16 to change the state of the product store locations P. The "0" output of each P location is connected to set the "1" state of the corresponding Q location. The "0" state of the Q location is reset by a RESET pulse on line 17 or 18 to change the state of the next higher P location via OR gate 16 if the Q location was previously in the "1" state. A number is entered in the register as in Fig. 1b Column 7 contains "0" and "1" so AND gate 15 is inhibited. A shift of each number occurs. Column 8 is unaffected but columns 6 contains two "1's" This causes P6 to be set to "1" and no other change. A further shift produces the result after step 3 in a similar manner. Step 4 produces columns 4, 5, 8 as above. In column 6 the two "1's" existing in the A and B registers cause P6 to change state to "0". This causes Q6 to be set to "1". At the end of the step Q6 is reset and causes P7 to change state to "0" which in turn sets Q7 to one, thus leaving the states shown in After Step 4. Similar operations occur in steps 5, 6, 7, 8.

Abstract: 1,241,418. Current and voltage measurement. UNITED KINGDOM ATOMIC ENERGY. Aug.1, 1968 [Aug.8, 1967], No.36472/67. Heading G1U. [Also in Division H4] An apparatus for measuring an A.C. signal 11 of any waveform comprises an A.C. amplifier 12, for receiving the signal and incorporating a variable gain control, a detector 13 detecting a characteristic value, e.g. mean square, peak, &c. of the A.C. amplifier output, a D.C. amplifier 14 providing an output corresponding to the difference between the detected value and a predetermined value and an overall feedback loop 16 from the D.C. amplifier output to the variable gain control. The arrangement is such that an increase in the detected A. C. signal will result in decrease in gain of the A. C. amplifier according to an exponential low. Arrangements connected at 15 responsive to the output of the D.C. amplifier provide a measure of the magnitude of the A. C. signal. The detector may be an indirectly heated thermistor. The controlled amplifier, Fig. 3 (not shown), incorporates an emitter driven logarithmic transistor T4 to which the input and control signal bias are applied via a unit gain amplifier circuit T1-T3. The transistor T1 is of the same type as T4 and is emitter coupled to T4 to provide feedback which compensates for temperature variation in the circuit.
