Patent ES-336789-A1 (ES)
Title: Material feeding apparatus with capacitive control
IPC: G05D9/12
Filed: 1967-01-31
Abstract: Material is fed from a first driven conveyer to a second and the depth of material on the second conveyer is maintained constant by applying signals from a capacitor type probe in a potential divider circuit to control the speed of the first conveyer. In Fig. 1, material is supplied from a hopper 10 to a first vibratory conveyer 13 which feeds it to a second vibratory conveyer 14 supplying a weighing hopper 11. During filling, the depth of material on the second conveyer influences the electrical capacity between an adjustbale probe 29 and conveyer 14. This capacity is included in a network supplied from a transistor oscillator in a unit 32 so that, after amplification and rectification, a direct voltage is produced corresponding to the depth of material on conveyer 14. This voltage is applied to vary the on/off time of a transistor blocking oscillator, during half cycles of an unsmoothed supply from a half-wave rectifier, so that the conductivity of a silicon controlled rectifier 102 in series with the driving coil 19 of conveyer 13 is correspondingly varied. The rate of feed by conveyer 13 is thus varied to maintain the depth of material on conveyer 14 at a value determined by the setting of probe 29 or a variable capacitor in unit 32. The rate of feed of conveyer 14 may be adjusted by a variable resistor (not shown) in series with its driving coil 25 and a switch 12 in this circuit is opened by hopper 11 to stop the feed when the hopper contains a predetermined weight of material.

Title: Shock resistant armature for electro-magnetic devices
IPC: H01H50/30
Filed: 1969-03-27
Abstract: The frequency of vibration of the armature of an actuator is reduced by forming it in two or more parts associated over their major faces but not rigidly connected together. As shown, Fig. 3, the armature of an actuator suitable for operation of a cross bar switch or relay, comprises two members 10, 11 which replace a similarly shaped and dimensioned onepiece armature of a known arrangement, Pigs. 1 and 2 (not shown). When energized, member 10 pivots about lug 12 and strikes the coil core setting up high-frequency vibrations, member 11 simultaneously pivots and strikes member 10 also setting up high-frequency vibrations, and the armature parts then stick together the two high-frequency vibrations combining to form a low beat frequency. This is said to reduce the chance of breaking the armature. The armature parts may be held together by an elastic member, e.g. a clip. The armature may be divided into more than two similar parts. The armature of a plunger style actuator may be subdivided along its length, and such an armature may be rectangular, Fig. 4 (not shown), or circular in cross-section.
