Title: Improvements in or connected with feed mechanism for use in association with automatic or semi-automatic weighing apparatus
Inventor: TERRY FRANCIS SIEV WRIGHT
IPC: G01G21/00
Filed: 1951-04-10
Abstract: 693,254. Automatic feed weighers. AVERY, Ltd., W. & T. April 7, 1952 [April 10, 1951], No. 8247/51. Class 143 [Also in Group XXX] Feed mechanism for automatic weighing apparatus, of the kind in which the final feed through a shoot 1 to the weighing receptacle is effected as a dribble, is characterized by a resiliently-mounted cut-off gate 2 carrying one part 6 of an electric vibrator mechanism which is operatively disposed in relation to the other part 7 when the gate 2 is in the closed position, leaving a dribble opening for control by the pivoted flap 9. The curved gate 2 is mounted by springs 3 on two pairs of arms 4 pivotally supported at 5. When a predetermined quantity of. the material has been fed to a weighing receptacle, the movement of the weighing apparatus trips a trigger mechanism to permit the gate 2 to swing closed. In this position, adjustable stops 8 are engaged by an arm 4 to ensure that the armatures 6 are operatively associated with electromagnets 7. These magnets are energized by alternating current with the result that the gate 2 is vibrated and effects a dribble feed over the edge 2a. When the correct weight is reached, a switch operates to open the circuit of a solenoid 11 allowing its armature 10 to fall and the flap 9 to close. A switch simultaneously breaks the circuit of the electromagnets 7.

Title: Improvements in and relating to Electric Motor Control.
IPC: H02P7/06
Filed: 1918-05-23
Abstract: 121,427. British Thomson - Houston Co., (General Electric Co.). May 23, 1918. Systems for continuous-current motors only.- The speed of a motor is controlled by a variable vibrating element operating independently of the motor. The shunt coil 10 energizes a core 15 which attracts an armature 13. The winding is then short-circuited by the switch 16 and the armature is released. As the armature vibrates, the contact 11 carried by it engages and disengages the contact 12, thereby periodically shortcircuiting the resistance R in the shunt field circuits of the motor. The speed of the motor may be varied by varying the rate of vibration of the armature 11 by adjusting the hand-wheel 17 of the contact 12, or by adjusting the screw 16<1>.

Title: Telecommunications exchange systems
IPC: H04Q3/54
Filed: 1974-02-27
Abstract: 1463364 Automatic exchange systems SIEMENS AG 27 Feb 1974 [9 March 1973] 8768/74 Heading H4K In a centrally controlled exchange, a register applies markings to a decoder according to the directory number of a called subscriber and thereby causes the line circuit associated with the called subscriber to be marked. A scanner then hunts for the marked line circuit and on its detection emits a code to the central control representing its position and hence the equipment number of the line circuit. The application is to a PBX when a subscriber goes off hook, closure of the line loop causes an input to be applied to a gate G in the associated line circuit TA2 and a hunting impulse to be emitted to a scanner S. In known manner the scanner hunts for the marked circuit and on finding it causes a three digit equipment number of the calling subscriber as identified by the position of the scanner to be sent to central control Z over coding wires A, using 1 out of ten markings on each of three groups of wires A1-A3. In known manner a connection is eatablished to a register WE via a single ended switching network K and the three figure directory number of a called subscriber is signalled to and stored in the register WE. When a digit evaluator WB signals that all three digits have been received, logic gates D are enabled and a code marking applied to wires R by the register and representing said directory number enables one of the logic gates, e.g. D1 to apply an input to a gate Gin the line circuit of the called subscriber. Gate G emits a hunting impulse to the scanner S whereby the equipment number of the called subscriber is determined and transmitted to the central control as for the calling subscriber identification. The subscribers are then interconnected in known manner. The codings wires A and R as shown are arranged for using 1 out of 10 markings on three groups of wires A1-A3, R1-R3 although a 2 out of 5 code or a binary code could be used, by employing only 5 or 4 A or R wires respectively.  To facilitate an easy change of the directory number of a subscriber associated with a particular line circuit the gates D may be coupled to the code wires R via multiposition switches which can be set so as to couple each of the three code inputs of each gate to any respective one of the code wires R, e.g. when using 1 out of ten code each logic gate input could be coupled via a ten position switch to one of the three groups of code wires R1-R3.
