Title: Apparatus for vibratory finishing
IPC: B24B31/073
Filed: 1972-09-05
Abstract: 1439749 Vibratory finishing ROTO-FINISH Ltd 5 Sept 1973 [5 Sept 1972] 41126/72 Heading B3D [Also in Division F2] A method of operating a vibratory finishing machine having an annular chamber 11 and a vertical rotatable shaft on which is disposed axially spaced eccentric weights 13, 14 one of which leads the other by a given angle, comprises driving the shaft in one direction with one weight leading the other, and altering the relative angular positions of the weights so that the second mentioned weight leads the first, the shaft being rotated in the same direction, whereby to impart to the mixture in the chamber a reversed circulatory movement which facilitates delivery of the mixture on to a separating screen. The chamber 11 is supported by springs 15 from a base 16 and a motor is mounted with its shaft extending along the axis of the chamber with the weights 13, 14 at opposite ends. During finishing, the material moves around the chamber in one direction and after finishing moves in the opposite direction, a flap 18 being lowered into the chamber so that the mixture moves on to a screen through which the finishing medium drops back into the chamber. The reversal of the circulation of the material in chamber 11 is effected by altering the angular position of weight 13 relative to weight 14. The weight 13 consists of a loose mass, such as balls 25, Fig. 5, which are disposed in a container 24 carried by an arm 23 rockable about a transverse pivot 22 on the shaft 21 of the motor 12, a toggle spring 26 being disposed between the arm and the shaft. In operation, rotation of shaft 21 for the finishing operation causes centrifugal force to act on the balls so that the arm 23 pivots to its opposite position (Fig. 6, not shown). At the end of the finishing operation, the rotation of shaft is stopped or greatly slowed down so that the balls roll, by gravity, to the opposite end of the container. Upon rotation of the shaft the arm again moves about its pivot but this time the balls are in the opposite angular position so that the direction of circulation of the material in the chamber is reversed. The shaft may rotate in the same or opposite directions.

Filed: 1960-12-01
Abstract: 922,773. Stop motions. ERNEST SCRAGG & SONS Ltd. Sept. 29, 1961 [Dec. 1, 1960], No. 41270/60. Class 120 (2). A stop motion for a textile machine operating on an even number of threads comprises a single finger on which is mounted a pivoted yoke device resting against the threads, the yoke device being so pivoted that breakage of at least one thread causes the finger to operate a yarn stopping or cutting mechanism acting on all the threads. In Fig. 2 the yoke device 12 pivoted on the finger 11 rests on two threads 16, 17 and maintains the finger upright against the influence of its weight. When a thread 16 or 17 breaks, the yoke 12 pivots and allows the finger 11 to fall to actuate a spring-influenced knife 18 of a mechanism which cuts both the threads. The breakage is brought to the attention of the operative by the displacement of the disc 20 mounted on the finger 11. For four threads a tiltable bar is mounted on the finger and two separate yokes are mounted at the ends of this bar. Specifications 842,463 is referred to.

Title: Digital electronic timepieces
IPC: G04G5/00
Filed: 1976-10-05
Abstract: 1526468 Electronic timepieces DAINI SEIKOSHA KK 5 Oct 1976 [9 Oct 1975] 41306/76 Heading G3T  An electronic timepiece with digital display (e.g. liquid crystal) has counters 104, 105, 106, Fig. 2, for counting local time and up/down counters 107,108, 109 for counting "different time" i.e. time in a different time zone or country. Selective manual operation of switches 121-127 enables display of either local time or "different" time and rapid setting of the time displayed. The "different" time display may be advanced and retarded. Switches 123-127 are ineffective when closed unless a safety switch 122 is closed to enable AND gates 136-140. Anti-chatter circuits 145-151 are connected to respective switches. A crystal controlled oscillator 101 output is coupled to frequency dividers 102, 103 which feeds 1 pulse per minute to minutes counters 104, 107 via switching circuits 117, 118 respectively. Counters 105, 108 count tens of minutes and step hours counters 106, 109 via switching circuits 119, 120 respectively. When all the switches 121 to 127 are open, switching circuits 117, 118 pass the 1 min signal from divider 103 to the mins counters 104, 107, the set output of a flip-flop 135 is low and data in counters 104, 105, 106 is coupled to de-coder/ drivers 113, 114, 115 via switching circuits 110, 111, 112 respectively, to display normal local time on display 116. When flip-flop 135 is reversed by closure of switch 121 the data in counters 107, 108, 109 is switched to the de-coder/drivers to display different time. SETTING. When switch 121 is open and switch 122 is closed, the divider 103 output is disconnected from the "normal time" counters, but counting of "different time" continues. If switch 124 is now repeatedly closed and opened, a pulse signal appears at the output of AND gate 137 and is applied to the hours counter 106 via switching circuit 119 to enable fast forward counting. Switch 125 is operated likewise to effect fast correction of the counters 104 and 105. Fast correction of the "different" time counters is effected upwards (advancing the display) when switch 126 is open and downwards when it is closed. If switch 123 is closed data in the normal time and different time counters are equalized. Reversible counters may also be employed for counting local time.

Abstract: 1511380 Winding up tapes or narrow fabrics; tension control BONAS BROS WEAVEMATIC LOOMS (ENGLAND) Ltd 8 Oct 1976 [10 Oct 1975] 41551/75 Headings DID and DIJ Tapes are supplied to one or more takeup cores 24-27, Fig. 3 by traversing tape guide chutes 20-23, there being means to (a) vary the traverse to enable any one of various package profiles to be wound and (b) means 39 to maintain a substantially constant tension in the tape or tapes during winding. In Fig. 2 a cam plate 37 traverses in synchronism with the chutes 20-23. The cam plate 37 moves between switches 33, 34 that serve to reverse the output of a gear box 31 driving the traverse mechanism. As the packages increase in diameter the resultant upward pivoting of the supply chutes 20-23 causes the cam plate 37 to rise up and, due to the shape of the cam plate 37, this causes the traverse stroke to decrease. The cam plate 37 may be replaced by other cam plates. The traverse means may include an endless belt (as shown) or by means of a lead - screw. The take - up cores 24-27 may be driven by a common drive belt that passes alternatively from one side of one core to the opposite side of the next core and so on. Tension Control. As shown in Fig. 3 the tension control may comprise a dancer arm at the end of which is a pulley 18 over which all the tapes pass. Upper and lower limit switches may be -associated with the arm. When the dancer arm contacts the upper switch the motor 32, Fig. 2, is stopped to stop rotation of the take - up packages. Contact with the lower switch causes the motor 32 to be switched on again. Additionally, in the electrical circuit between the upper switch and the motor 32 there may be a time - delay mechanism. The result of this is that which ever of the tapes is responsible for causing the dancer arm to swing upwardly, switching off the motor 32 is delayed whilst the other tapes continue to be wound up, wind - up of the shortest tape being delayed by -a slip - drive between the associated take - up core and the common drive belt.
