Title: Weft stop motion device for a shuttleless loom
IPC: D03D51/34
Filed: 1962-08-31
Abstract: 985, 831. Loom stop-motions. R. DEWAS. Aug. 31,1962 [Sept. 8,1961], No. 33511/62. Heading D1E. In a weft stop motion device for a shuttleless loom in which one of a number of weft threads 11-14 are selected by selector members 6-9 and presented by a member 15 to a weft inserter needle 16 for each pick, the selected thread is also caught by a pivoted hook 27 carried on the slay 1 on the backward movement thereof. On the picking movement of the needle 16 the thread is tensioned which applies a force on the hook to lift it and move an arm 28 see Fig. 6, against a leaf spring 30 off an electrical terminal 37 to break the circuit of a relay 46, which when energized is adapted to break the circuit of the driving motor 50 of the loom. The circuit of relay 46 is also controlled by a cam 44 so that voltage is only applied to terminal 37 during the picking operation. If sufficient tension is not applied to the weft thread, as a result of a break or the supply being exhausted, the hook 27 is not lifted and the arm 28 remains in contact with terminal 37, the circuit of relay 46 is completed and the motor 50 is stopped. The hook 27 may be spaced from the edge of the fabric or it may be positioned close to the reed 2 and the edge of the fabric. In the latter case the reed assists in guiding the thread into the hook 27. In this case also means may be provided for moving the hook device 27 at certain times to clear a temple cover, for example. The relay 46 could control a clutch operating circuit instead of the motor 50 direct.

Title: Improvements in talking machines
IPC: G11B17/00
Filed: 1927-12-12
Abstract: 311,432. Jevons, W. H., and Norton, F. D. Dec. 12, 1927. Driving ; cases. - Relates to gramophones wherein the driving-motor is energized by manipulating the lid of the cabinet. According to the invention, a drivng-shaft or drum rotatable by one or more springs or weights, and connected to the turntable spindle through a freewheel clutch, is so connected to the lid that the springs are rewound or the weights raised by opening the lid. In the construction shown, two springs A<2> are provided, the outer end of each being connected to a barrel A fixed on a hollow shaft or drum B. The inner end of each spring is attached to a fixed bar b. The shaft B is geared to the turntable spindle a through a freewheel clutch D and gears d. Connected to and wound round the shaft B are one or more cords E, which are also attached to the lid C<1> of the cabinet. Two cords are preferably employed as shown, and are connected together at e<1>. The lid is counterbalanced by springs F, or by weights, so as to remain poised in any position. When the lid is opened, the cords E are drawn 'off the shaft B, rotating it and so winding up the springs A<2>. Then, on closing the lid, the slack in the cords is taken up by weights G thereon, which sink to the position shown in chain lines, Fig. 4. As the springs run down, driving the machine, the cords are wound back upon the, shaft B. In a modification in which a shallower cabinet is provided, springs arranged substantially horizontally are employed to draw the cords taut, instead of weights such as G. In place of springs, a weight may be used to drive the shaft B through a cord or chain wound thereon. A weight W may be fitted into the cabinet, near the base, to resist the upward force applied during winding, or a foot-board may be provided instead of this weight. A modified construction (Fig. 6, not shown) is also described, in which the lid carries a toothed quadrant engaging with the winding-gear of the motor. In this case, the inner ends of the springs are connected to a spindle which is rotated through ratchet-gear, for winding, when the lid is opened.

Classes 120(2) and 120(3) Cored yarn packages 10, such as pirns, from an automatic winder are collected and stacked without contact with the wound yarn by receiving each package from the winder in a cradle 15, 16, complementary to the ends of the core, traversing the cradle relatively to a receiving rack 32 having core-end locating means in the form of notches 34, delivering each package from the cradle to the notches in positional sequence in the rack, and returning the cradle for receipt of the next package. The cradle members 15, 16 are carried on a cross shaft 17 pivoted to nuts 18, 19 on feed screws 20, 21. Cradle member 15 is connected by a toggle link 31 to one arm 30 of a three-armed lever 29, 30, 36 pivoted to a plate 27 depending from nut 18. Rack 32 is slidably mounted in channels 33 and has a slot 35 for the passage of arm 29 which acts as a feeler. In operation, a doffed pirn falls between guides 13, 14 until its ends rest in the cradle members 15, 16. A yarn collector 43 swings across and takes the yarn leading from the pirn to scissors 44 where it is severed. Screws 20, 21 are now driven from a shaft 26 to lower the cradle in front of rack 32. When feeler 29 engages a pirn already in the rack, or the rack bottom, it tilts the cradle to discharge the pirn into the notches 34 above. When a lug 42 on plate 27 engages a peg 41 it shifts a rod 39 to reverse the drive to shaft 26. The cradle is then raised again until lug 42 engages a peg 40 to stop the drive, arm 36 meanwhile being moved by a stationary cam to reset the toggle and return the cradle to its original position. Mechanism may be provided whereby tipping of feeler 29 for filling the top notches in the rack also operates a stop motion for the winder.

Abstract: 1,158,223. Moulding bricks. CANNERTON BRICK CO. Ltd. 21 July, 1957, No. 33626/67, Heading B5A. A specially shaped building member, e.g. a brick, is prepared by moulding a generally rectangular block with at least one passage through the block from top to bottom and at least one channel in both the side surfaces. At least one channel is then formed in each of the top and bottom surfaces by pressing. As shown, the first mould comprises sides 1, carrying channel forming members 2 and a base 5 perforated to allow a piston to pass through from below. Vertical members 4 shape the passages through the block and a base 3 can slide over the members 4 to eject material from the mould. The mould is placed in a former which closes the sides and is filled with moulding material. Base 3 is then raised by a piston. The brick is then transferred to another mould mounted in a press, the mould comprising a base member 12 with channel forming members, a similar top member 10, side members to engage the channels already formed, movable core members 28 engaging the passages through the brick and a press box 16 surrounding the mould. The press comprises sliding platens 19, 20 moving in a rigid frame 17, 18 to which the press box 16 is mounted and core members 28 on a spring mounting 24, 25, 26. In operation the platens 19, 20 are raised so that the mould clears the press box 16. The brick is pushed into the mould cavity and is located on the end of core members 28. The platens are then lowered and pressure applied to the top platen 19, the bottom platen abutting against the fixed members 26 and 24. The brick is removed by raising the platens to a higher position than for loading and pushing the brick from the mould cavity. The channels are preferably moulded so that one or preferably two continuous channels extend right round the block and the channel on the sides of the block is dovetailed. Apparatus, e.g. a fixed cutter or rotating miller, may also be supplied to trim the channels to the desired shape.

Abstract: 1386437 Monostable circuits ROBERT BOSCH GmbH 19 July 1972 [20 July 1971] 33681/72 Headings H3T and H3P In a monostable multivibrator having the control electrode of a first amplifier 14 capacitance coupled to the output electrode of a second amplifier 18, the output electrode of the amplifier 14 direct current connected to the control electrode of the amplifier 18 and the output electrodes of both amplifiers 14 and 18 and the control electrode of the amplifier 14 each connected via a respective load 24, 26, 25 to a current supply line 23, a series combination of a resistance 30, 32 and a switch 29 is connected in parallel with the load 24 of the first amplifier 14, the switch 29 is closable for triggering the monostable into its unstable state and a capacitor 34 is connected from the control electrode of the amplifier 14 to a supply line 22 to which reference electrodes of the amplifiers 14, 18 are connected. When a keying switch 29 is depressed the potential on the electrode 13 goes more positive. However simultaneous increase in the collector current through transistor 14 cannot occur since the potential at the control electrode 11 is temporarily held by the capacitor 34. The voltage jump which occurs at the output electrode 13 is applied via 21 to render the transistor 18 canductive to operate the relay 26. The branch 20 renders the transistor 14 blocked and this transistor remains blocked until the capacitor 19 has attained a charged state to make transistor 14 conduct and transistor 18 block. The transistors 14, 18 may be replaced by PNP-type or thermionic tubes.
