Patent GB-463096-A (GB)
Title: Improvements in the manufacture of electric resistances
IPC: H01C7/04
Filed: 1936-09-29
Abstract: An electric resistance consists of two or more heat-refractory heavy metal oxides having space-lattices of different types with substantially different spacing of the atoms or molecules, excluding the rare earth metal oxides and zirconium oxide, the oxides being intimately united by melting or sintering.  By "heavy metals" are meant metals heavier than aluminium.  It is stated that the resistance so produced has at room temperature a specific resistance higher than that of any of the oxides taken separately.  The value of the temperature coefficient of the composition may be controlled, e.g. by mixing an oxide having a positive coefficient, e.g. cadmium oxide, with an oxide having a negative coefficient.  In examples, the following combinations are used: (1) equal proportions of cadmium oxide and ferroso-ferric oxide, sintered at about 1300 DEG  C.; (2) copper oxides plus bismuth oxide, Bi2O3; (3) cadmium oxide, chromium oxide and lead monoxide, the lead monoxide being a flux which may be partly or wholly removed in the burning.  Specifications 165,051, 165,052, and 179,928, [all in Class 22], are referred to.  The Specification as open to inspection under Sect. 91 refers to the use of copper chromate instead of an oxide.  This subject-matter does not appear in the Specification as accepted.

Title: Material Feeding Apparatus
Inventor: STEEL HENRY JOHN
IPC: G05D9/12
Filed: 1966-01-31
Abstract: 1,178,674. Automatic level control. AUTOPACK Ltd. Feb. 2, 1967 [Jan. 31, 1966], No.4097/66. Heading G3R. 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.
