Title: Apparatus for dimension controlling
IPC: B21B1/22
Filed: 1955-03-08
Abstract: 810,118. Automatic control systems. COMPAGNIE DES FORGES DE CHATILLON COMMENTRY & NEUVES MAISONS. March 8, 1955 [March 10, 1954], No. 6824/55. Class 38(4). In a servo system, planet wheels of a differential gear are respectively rotated in proportion to the values of a quantity before and after modification, satellite wheels of the differential gear being rotatable about radii of a carrier wheel which controls modification of the quantity. In Fig. 1 material, e.g. metal strip, to be rolled passes between pressure rolls 1<SP>1</SP>. Guide roller 3 rotating at a speed dependent on the speed at which the material enters the rolls is coupled to one input shaft of a differential gear A through a variable speed gear 17, and a guide roller 4 rotating at a speed dependent on the speed at which material leaves the rolls is coupled to the other input shaft of the differential gear. Deviation in the ratio of the speeds at which the material enters and leaves the rolls from a value determined by the setting of gear 17 thus results in movement of the output shaft of the differential gear to adjust a rheostat 15 in the field circuit of a motor 16 driving a winder for the material leaving the rolls. The resulting change in speed of the material through the rolls is such as to correct the deviation in the speed ratio and thus maintain a constant elongation of the material. Alternatively or in addition automatic correction of the speed ratio may be effected by variation of the pressure of the rolls. In a modification, Fig. 2 (not shown), the input shafts of the differential gear are coupled to separate friction rollers displaced in accordance with the thickness of the material entering and leaving the rolls. Specification 630,989 is referred to.

Title: Improvements relating to automatic weft replenishment in looms
IPC: D03D49/70
Filed: 1951-03-22
Abstract: 727,016. Automatic cop changing mechanism cutting weft. PROTOTYPA, NARODNI PODNIK. March 22, 1951 [March 23, 1950], No. 6977/51. Class 142 (2). The operating mechanism for the cop inserting hammer incorporates a weft cutting and clamping device which also acts as a feeler to prevent cop changing if the shuttle is wrongly positioned. The cutting and clamping device comprises concentric sleeves 7, 13 having normally horizontal diametral slots 8, 14 which are rounded on the edges nearer to the fabric and sharp on the opposite edges. When cop changing is initiated, the mechanism is raised into the path of the shuttle box 2 so that, if the shuttle 4 boxes correctly, the weft enters the slots ; the slay lifts a pawl 23 and slides the inner housing 9 of the device against a spring 27, causing the pawl to rock a lever 18, which turns the inner sleeve 13, whereby the weft is cut and clamped as shown in Fig. 4 ; the pawl then encounters a tooth 22 on the outer casing 21, thereby moving the mechanism as a whole to actuate the hammer 33. As the mechanism returns to the position shown in broken line, it takes the clamped weft (which extends from the selvedge) below the level of the shed and releases the cut end, this action being effected by a fixed stop 25 which turns the inner sleeve to re-align the slots. If the shuttle does not enter the box correctly, a solid part of the shuttle pushes the sleeves against the action of a weak spring 26, so that lifting of the pawl 23 by the slay is prevented by a projection 231 on the pawl encountering a solid part 16 of the inner sleeve ; the inner housing 9 then slides, against the action of the spring 27, without operating the hammer 33.

Abstract: 1424512 Automatic voltage control LUCAS ELECTRICAL CO Ltd 24 Jan 1973 [19 Feb 1972] 7785/72 Heading G3R [Also in Division H2] A protection arrangement for the battery charging system of a road vehicle comprises means whereby when a fault occurs in the system the arrangement operates to provide two levels of protection. The electrical system of a road vehicle comprises an alternator 11, the output of which is rectified by diodes 12, 13 to charge a battery 16 and by diodes 17, 13 to provide a supply for the various electrical loads 22 of the vehicle. Connected across the output leads 18, 15 is a protective device comprising a thyristor 41 and in parallel therewith the series connection of a voltage dependent element such as a Zener diode 42 and a resistor 43 arranged to have low inductance, for example a printed circuit resistor, the gate of the thyristor 41 being connected to the junction of the diode 42 and the resistor 43. When an overvoltage occurs on the line 18 the Zener diode becomes conductive and current flows through it and the resistor 43. At low values of current the thyristor 41 stays non-conductive and protection is afforded by the diode 42 and resistor 43. Should the value of the current be high the voltage across the resistor 43 reaches a value suffucient to trigger the thyristor 41 which conducts to afford a second stage of protection. The system includes a voltage regulator for the alternator and includes a potential divider 24, 25 and a Zener diode 26 which co-operate to control a transistor 27 which itself controls two further transistors 32, 33, a feedback circuit 36, 37 being provided so that the regulator oscillates to control the current in the field winding 24 of the alternator so as to maintain the alternator output voltage at a value set by the adjustable resistor 25.
