Abstract: 953, 806. Shuttleless looms; weft pattern mechanism. SULZER FRERES S. A. April 17, 1961 [April 26, 1960], No. 13800/61. Heading DIE. The weft changer 138 of a gripper shuttle loom is locked for the greater part of each weaving cycle by a roller 53 engaging the appropriate notch 142a-d. The roller is withdrawn for a short period to allow the weft changer to swing to a new position which has been pre-selected by the dobby earlier in the cycle, the movement being effected by means which attempt to swing the weft changer but cannot do so until it is unlocked. As shown in Fig. 11, the dobby sets switches 132, 133 to energize a selected winding 126a-d of a solenoid, the armature 134 being attracted into the energized winding when the roller 53 releases the weft changer. In another form, the weft changer is linked to an intermediate point of a floating lever, the ends of which are displaced by the dobby through spring connections; the springs are compressed by the movements imparted by the dobby and expand to move the floating lever when the roller 53 releases the weft changer; hydraulic cylinders coupled to a hydraulic accumulator may replace the springs. Dashpots are provided to damp the movements of the floating lever.

Abstract: 101,715. Musitelli, R. Oct. 2, 1916. Breech actions, sliding barrel and breechblock.-Consists in the arrangement of the return spring and buffer spring for the breechblock of an automatic pistol or other small-arm. The return spring 10 is located in a chamber above the breech-block and is wound on a stem which forms its rear abutment. The stem is capable of sliding rearwardly against the action of a buffer spring 14, and thus forms a yielding stop for the breech-block. The barrel and breech-body recoil for a short distance, until a shoulder 38 on the body abuts against a shoulder 39 on the frame, and by this recoil a locking-bolt 37 is depressed, whereupon the breech-block 8 recoils against the springs 10, 14. The locking-bolt is pivoted to a lever 51, which is pivoted to the frame and acted on by a spring 49. The rear abutment of the firing-pin consists of a pin 19 fixed to the breechblock and entering a slot in the firing-pin. At the rear of the hammer is a safety device comprising a rotary plug 53 having a side projection 54 adapted, in the firing position, to register with a slot in the breech-block to permit of the normal firing-movement of the hammer. The trigger mechanism comprises a pivoted sear 28, a searactuating lever 31, and a link 32 terminating in a trigger 33. The ejector 41, Fig. 2, is formed on a rotary plug 44, Fig. 5, projecting through the side wall of the breech-body and provided with an external lever 43, by which it can be rotated to set the ejector 41 in a transverse position, as shown in dotted lines in Fig. 2, for the purpose of retaining the breech-block.

Abstract: 1380464 Electronic timepieces TIMEX CORP 24 March 1972 [24 March 1971] 13997/72 Heading G3T In a timepiece controlled by a quartz crystal oscillator 10 via a frequency divider 12 and a driver circuit 16 which feeds pulses of alternating polarity to the oscillatory rotor of an electromechanical transducer 18, the driver circuit has two inputs 13, 14 receiving anti-phase output signals from the divider, transistors 19, 21, 22 being coupled to the input 13 so as to saturate in response to a rising potential on that input, and transistors 24, 26, 27 being coupled to the other input 14 so that ground potential thereon simultaneously cuts off the latter transistors. With a rising potential on input 14 and ground on 13, the reverse effect occurs. The length of driving impulses on line 17 to the rotor can be adjusted by R-C networks 28, 29 and 31, 32. The transducer comprises a coil 33 which oscillates between positions defined by sets of fixed permanent magnets 36, 37 and is attached to an index lever staff 34; arms 39, 41 of the lever advance a ratchet wheel 43. If the coil 33 becomes displaced by mechanical shock to the other of its two positions, synchronism is restored at the instant of the next pulse which is ineffective on the coil. A number of coil forms are suggested. Magnetic detenting of the rotor is provided by a ferrite or iron core 44 carried by the coil and co-operating with fixed permanent magnets 46, 47. Each pulse through the coil so magnetises the core 44 as to cause repulsion from the adjacent magnet and attraction to the other.

Title: Maximum signal identifying circuit employing transistors
IPC: G06V10/75
Filed: 1960-04-21
Abstract: 908,225. Automatic character recognition. GENERAL ELECTRIC CO. April 21, 1960 [May 1, 1959], No. 14008/60. Class 106 (1). [Also in Groups XXXVI and XL (c)] A circuit for identifying at an output terminal the one of a plurality of signals applied to a plurality of input terminals having an extreme value, more particularly for use in a character reading system, comprises a plurality of transistors each having one electrode coupled to an input terminal an output electrode and a third electrode connected in common so that if the extreme signal exceeds the other by a predetermined amount the corresponding transistors conduct and a bias is applied via the common connection to the other transistors to prevent them from conducting. In the Figure the input terminals S1 S2 &c. receive signals from correlators which compare a character that has been read with a number of reference characters so as to produce an output signal at one of the terminals 40, 41 &c. corresponding to the reference character most closely resembling the input signal. An input pulse applied terminal 69 renders the circuit operative and the transistor having the largest signal applied to its base conducts producing an output signal at the corresponding output terminal. Bias is applied from the emitter of the conducting transistor to all the other transistors and this bias will normally be sufficiently larger than all the other signals that the other transistors do not conduct. However, if the difference between the largest signal and the next largest signal is small, more than one transistor may conduct. The value of this difference depends in part upon the value of resistors 45, 46 &c. connected in the emitter circuit. The simultaneous conduction of two transistors indicates an error condition. It is stated that in a system for reading the characters on cheques, fourteen transistors may be provided, ten representing the numerals 0 to 9 and the remaining four for identifying the account number, a monetary unit value of a cheque and other " fields " containing information.
