In the embodiment shown the bush, Fig. 1, is of nylon and has a head portion 1 of oval cross-section and a shank 2. In use the head portion 1 is inserted into a rectangular aperture whose length and width are the same as those of the oval cross-section of the head, and is rotated about its axis so that the edges of the aperture cut into the bush at 14 and abut stops 5 on the head. The stem 8 is then pushed into the bush until an annular flange 4 in the bore of the bush interengages with a peripheral groove 9 on the stem. The stem 8 projects from the base of a socket 7 in the handle which is shaped to receive the shank 2. In other embodiments the constricted region of the bore of the bush is formed by inwardly projecting fingers, and the shank 2 is of circular cross-section.

Abstract: 875,498. Electric-selective signalling systems. DATEX CORPORATION. Jan. 26, 1960 [April 13, 1959], No. 2812/60. Class 40 (1).  An apparatus comprises a source of binary coded signals, circuit means coupled to be responsive to these signals and switchable between a follow mode for continuously transmitting the signals and a storage mode for storing a preselected signal from the source, and control means for effecting the said switching. A rotating disc 16, Fig. 1, is conventionally sensed by brushes 18 and the output passed through a circuit 20 and a decimal converter 22 to a visual following element 24. Means 26 provided for print out operations are actuated by a command device 30 which changes over a switch 28 and biases the circuit 20 to store the present input and to be unresponsive to any subsequent inputs. The command device 30, Fig. 2, is a bi-stable circuit designed to supply a negative potential on bus 32 and ground on bus 34 and vice versa to switch each of the circuits A-D (one for each brush) to the " follow " or " store mode " respectively. In the " follow " mode diode circuit 92, 100, 96, 102 is biased so that when brush 18A is on a non- conducting segment transistor 74 conducts and relay 80 is not energized, and when brush 18A is on a conducting segment transistor 76 conducts and relay 80 is energized. Thus the state of energization of relay 18 depends upon the input track A. In the " store " mode, whichever transistor is conducting upon the application of the bias voltage is maintained conducting, andthus the relay winding 18 is maintained either energized or not energized.

Abstract: 250,703. Le Tall, F. W., (Westinghouse Electric & Manufacturing Co.). Feb. 2, 1925. Wired-wireless systems.-In a carrier current system for transmitting energy over an electrical conductor system, an auxiliary conductor system, for conveying the carrier current over a section offering a high impedance thereto, comprises members inductively or capacitatively coupled to the main conductor system on each side of the high impedance portion and a single circuit tuned to the carrier current frequency, or two such circuits electrically coupled together, which circuit or circuits is or are conductivelv connected between the coupling members and earth whereby extraneous frequencies are eliminated and dangerous potentials prevented from arising on the auxiliary conductor system. In the arrangement, Fig. 1, the auxiliary conductor system for bridging over sectionalizing apparatus &c. 3, connected to high tension transmission lines 1, 4, comprises conductors 6, 7 supported parallel with lines 1, 4 respectively and joined at 8 to a third conductor 9 connected to earth at 12 through a tuning coil 11. In the modification, Fig. 2, the conductor 6 is connected to a tuning coil 15 and the conductor 7 to a tuning coil 16, the coils being placed in inductive relation and connected to earth at 12 by wires 17, 18.

Title: Improvements in stop mechanisms for drawing frames and similar textile machines
Inventor: MACKIE JOHN PRINGLE
IPC: D01H13/16
Filed: 1951-02-07
Abstract: 706,192. Stop mechanism for drawing heads. MACKIE & SONS. Ltd.. J. Feb. 7. 1952 [Feb. 7, 1951]. No. 3049/51. Class 120(2) A stop mechanism for a drawing head of textile machines has a detector member which is caused to move relatively to the fibrous material in a closed path in such a way as to engage over part at least of its path of movement, the fibrous material during its passage from the drawing rollers, and which in the event of disruption of the fibrous material is caused to depart from its normal path of movement and so operate a stopping device. As shown, a detector 10 bears on the sliver 1 between drawing rollers 2 and 3 and delivery rollers 6 and 7. The detector 10 is pivotally mounted by a pin 11 to a bracket 12 turning with a rocker shaft 13 which is rocked by a connecting rod 14 connected to an eccentric 15 driven by meshing gears 16 and 17, the latter being mounted on the shaft of delivery roller 6. The rod 14 can slide through a bush 21 turning on the end of link 22 rigidly mounted on shaft 13 and the operative thrust is transmitted from the rod 14 to the bush 21 by means of a coiled spring 24. As the eccentric rotates so the rod 14 transmits a rocking motion to the link 22 causing. the shaft 13 also to rock which thus causes detector 10 to reciprocate. The detector 10 only contacts the sliver for a short portion of its travel however, it being lifted clear for the remainder of its travel by the engagement of an extension 26 with a camming surface 27. If the sliver breaks or becomes thin, the detector 10 is allowed to drop and a shoulder 28 then comes into contact with the edge of sliver plate 5 which stops the movement of the detector and consequently the rocking of shaft 13. The thrust of the rod 14 then compresses the spring 24, and the collar 25 moves towards the bush 21 causing a pivoted arm 30, with which it engages, to operate the plunger of a switch 32 to stop the machine. The mechanism may also be made to operate in a similar manner in the event of an abnormally thick sliver passing, by the extension 26 coming into engagement with a stop-member 41 as shown in Fig. 6.

Abstract: 1,030,031. Tractor power lift mechanisms. MASSEY-FERGUSON Inc. Jan. 24, 1984 [Jan. 24, 1963], No. 3131/64. Heading A1P. A tractor power lift mechanism is characterized by two hydraulic actuators 30 each associated with a lift arm 32 for raising a draft link 16. The lift arms are coupled by two rods 38, 39 having interengaging teeth 40, 41 which can be selectively displaced axially of the rods to allow a limited rotative movement between the rods and thus the lift arms whereby lateral tilting of an attached implement is achieved. The teeth 41 can be moved axially of the rod 39 against a spring bias by means of a screw operated by a handle 52. For locking the lift arms against movement, in order to operate draft control, a pin 72 fixed to the tractor frame can be turned to engage in a jaw 71 in an arm 70 fixed to the rod 38. For normal operation a groove 73 in the pin registers with the arm 70 to allow it to move freely. To operate a follow-up linkage on movement of the lift arms a sensing lever 60 is operated by a rod 67 bridging the coupling teeth 40, 41 whereby an average of the movements of the separate lift arms is transmitted to the follow-up linkage.
