Filed: 1936-12-31
Abstract: 487,879. Weighing-apparatus. TAYLOR, R. J. S. Dec. 31, 1936, No. 35825. [Class 143] Apparatus for use in the feeding of animals comprises a main container for the foodstuffs, with sloping walls leading to a relatively small opening at its lower end, manuallyoperable means for opening and closing the opening, and a weighing mechanism adapted for supporting, beneath the opening, a container which is movable relatively thereto. As shown, the movable container 24 is attached to a rod 29 passing freely through holes in a weighing lever 16 fulcrumed on a pivot 17 and supported by weighing springs 18. The food is admitted from the main container 12 by a manually-operated slide 13 which is closed by the operator when a pointer 19 indicates that the requisite weight has been delivered. The operator now pushes in, and then rotates, a rod 35 connected to the rod 29 by a loop 29a. The movable container 24 is thus moved over two oppositely-directed shoots 32 and the contents is tipped down one or other of the shoots according to the direction of rotation. The shoots direct the food to troughs or mangers. Stops 37 limit the rotation of the movable container. In a modification, the movable container is provided with trunnions resting in notches in the weighing lever. The operator after weighing out the requisite quantitydetaches and empties the contents into the animal's trough. Specification 439,382 is referred to.

Title: Improvements in and relating to apparatus for straightening wefts in fabrics
IPC: D06H3/12
Filed: 1934-12-14
Abstract: 446,446. Feeding webs. BLEACHERS' ASSOCIATION, Ltd., Blackfriars House, Parsonage, Manchester, and CUNLIFFE, W., 189, Crown Lane, Horwich, both in Lancashire. Dec. 14, 1934, No. 35879. [Class 100 (i)] A weft-straightening machine comprises two cylindrical rollers 4, 7, made up of separate rotatable sections and spaced a suitable distance apart, and over which the fabric 18 to be treated is drawn, each roller having a co-operating tapered roller 9, 10, the tapers of which are in opposite directions and the spindles set at an angle which ensures that the tapered faces of the rollers are parallel to the fabric where they touch it, the two rollers 9, 10 being mounted at their ends in a single pivoted mounting which when operated will cause one or other of the tapered rollers to press more heavily on the fabric, the drag on the fabric thus exerted by the wider end of the tapered roller tending to move the displaced end of the weft into line with the undisplaced end. The mounting for the rollers 9, 10 comprises two pivoted discs 8, one on each side of the machine, in which the spindles of the rollers are mounted and which are connected by rods 16 so as to rotate as a unit when a hand wheel 11 is operated. The discs 8 also carry supports in which is mounted the spindle 5 of the roller 4 and this spindle may be slightly below the axis about which the discs 8 rotate or may be concentric therewith. A further guide roller 17 which may be in one piece or formed in sections is provided. In operation, when the weft is seen to be displaced, the operative rotates the hand wheel 11 in one direction or the other to lower one tapered roller and raise the other roller and preferably also the roller. 4, whereby a drag is exerted by the wider end of the lowered, tapered roller which straightens the displaced end of the weft.

Abstract: 960,014. Separating solid materials. ERNEST NEWELL & CO. Ltd., and P. HOWDEN. May 31, 1962 [Oct. 6, 1961], No. 35964/61. Addition to 759,444. Heading B2H. A grading machine has two pairs of rolls, 1, 2, and 3, 4, the rods being arranged parallel to each other and being rotatable in the same direction, an independent drive being provided for each roll of each pair with provision for the adjustment of the speed of one roll of one pair relatively to the other, the rolls having grooves spaced along their length to provide generally square apertures 19 for the passage of undersize material, and an inclined shoot plate 8 being provided to direct oversize material from the first of the roll-pairs 1, 2 to the second 3, 4. The rolls are mounted on shafts 1A, 2A, 3A, 4A each driven by a motor 13 through reduction gearing 14, the motors 13 being arranged alternately on opposite sides of the machine. The rolls are disposed to give a general inclination through the machine from a material dump plate 7 to a shoot plate 12 for oversize material, the first roll of each pair (i.e. the rolls 1, 3) being of larger diameter than the second roll in each pair, and the shoot plate 8 being disposed to form a well between the two pairs of rolls for accumulation of material from the first pair of rolls 1, 2. The rolls 2, 4, together with their motors 13 are adjustable towards and away from the rolls 1, 3 respectively on slides 16, the shoot plate 8 being in two parts to allow for this, and material passing between the rolls falls down a shoot plate 10 to a conveyer (not shown). Each roll is constructed of elements 20 having V-shaped edges, and notches 21, Fig. 5, are provided in the edges to carry lumps of material either into or out of the nip of each pair of rolls. The rolls 1, 3 are driven through V-belt transmissions 15A so that if a lump of material is jammed by the notches 21 on these rolls between the rolls of a pair then the transmission will take the impact until the lump is gripped by notches 21 on one of the rolls 2, 4 and is thus removed to one of the shoot plates 8, 12. The rolls 2, 4 are driven through chain transmissions 15B.

Title: Process and apparatus for evening silvers
IPC: D01G23/06
Filed: 1972-08-03
Abstract: 1393775 Carding; drawing; regulating and tensioning sliver ZELLWEGER USTER Ltd 3 Aug 1972 [7 Sept 1971] 36237/72 Headings DID D1F and D1N In a textile sliver producing machine e.g. a carding-engine or set thereof, the speeds of sliver feed members and drafting rollers are both regulated according to long-term and short-term fluctuations in supply and thickness of the fibre material, and employing a sliver reservoir the average filling level of which is maintained constant by such regulation, in order to yield a collected e.g. coiled, sliver of generally uniform cross-section or weight per unit length. The card shown comprises a main cylinder 1 preceded by licker-in 2 and feed roll 3 (acting as a regulating unit) and doffer 4. The carded web is removed by comb 5 and formed into a sliver which passes through a drawing apparatus 7 (acting as a second regulating unit) having back rolls 8 driven at constant speed and front rolls 9 driven at a variable speed by a variable drive 10 according to fluctuation in fibre thickness as measured by element 6 arranged in front of (or inside or behind) apparatus 7. A measurement-initiated signal or a manipulated variable from speed regulator 12 correctively controls the speed of roller 3 through a controller 13 (provided with an integrating component) and a variable drive 17 to adjust the quantity of fibrous material supplied and (through variable drive 10) the draft of apparatus 7. In order to correct brief speed differences between rolls 9 and sliver slack being coiled into a can 16, the sliver passes into and is withdrawn from a reservoir 11 the filling level of which is monitored, as by photocell 15, to produce a signal which initiates operation of drives 10 and 17 whereby the measured sliver level in the reservoir remains within predetermined limits. In a modification, Fig. 2 (not shown) reservoir 11 is disposed between apparatus 7 and conventional calender rollers (not used in the apparatus of Fig.). The filling level in the reservoir 11 may be controlled rather than measured: thus, the deviation from the average draft between rolls 8 and 9 is integrated by means of a mechanical differential, Fig. 3 (not shown) the output of which adjusts a rocker arm so as to adjust correctively the length of sliver carried around a fixed roller and two rollers on the arm.

Title: Electric cut-out or protective systems with automatic circuit breakers
IPC: H02H3/16
Filed: 1932-12-23
Abstract: 411,942. Protective cut-out arrangements. HASLEV, A. M., 9, Frederiksplads, Randers, Denmark. Dec. 23, 1932, No. 36527. [Class 38 (v).] In a protective arrangement applicable to two wire systems one of which is earthed of the type in which an electromagnet in the earthed conductor maintains a switch closed in the line conductor while one or more of the consuming devices are connected to the load circuit and on opening connects a fuse of lower rating that of the main fuses in the leakage path, the armature controlled by this electromagnet together with the movable switch parts which it controls are arranged to be in a position of balance or poise when the armature is in its "rest" or unoperated position. As shown in the Figure the lines 0, 1 supply loads 10 the line 0 being earthed and having in series a coil 2. Normally an armature 3 engages a contact 6 in the live main but when all the loads are disconnected the spring 5 moves the armature to the position shown breaking the direct connection between the main and the load circuit. A fuse 7 and indicator lamp 8 are now connected in the live wire circuit, the fuse 7 being of relatively small capacity so that when any appreciable leakage to earth from the live wire takes place the fuse is ruptured and the circuit isolated. In accordance with the invention the armature 3, when in its unoperated position, is in a state of poise or balance, the spring 5 in this position being arranged to exert no force on the armature. Thus inadvertent operation of the armature due to external vibration is prevented. Other forms of armature fulfilling this condition may be employed and the circuit may be arranged to be controlled not by the armature itself but at separate contacts, for example, those of a mercury tilting switch, the armature and associated mercury switch being together balanced in the unoperated position.

Title: Improvements in the treatment of glauconite
IPC: C01B33/46
Filed: 1933-12-30
Abstract: Washed and cleaned glauconite is subjected to a dehydrating heat treatment under reducing conditions at 450--750 DEG  C. and then digested with caustic alkali of concentration greater than 15 per cent, whereby its base-exchanging capacity is increased permanently. The reducing agent for the heat treatment may be hydrogen, town gas &c., but preferably the glauconite is mixed with heavy commercial fuel oil and subjected to direct flame heating at 535--650 DEG  C. Hot caustic soda solution of 35 per cent strength is preferably used for the digestion, which may be effected at boiling point.  With more dilute solutions, temperatures above boiling point may be used under pressure. Sodium silicate may be added to the caustic soda, which is used for successive batches of glauconite and periodically purified and brought back to the desired strength.  The surfaces of the treated glauconite may be stabilized by successive treatment with dilute solutions of alkali silicate and of an acid-reacting salt such as aluminium sulphate.
