Title: Rocking melting furnace for metals - melts charge dropping from shaft by heat shock and hot wall contact
IPC: F27B19/02
Filed: 1975-12-12
Abstract: A metal melting furnace consists of a horizontal drum which can be reciprocated and receives the charge at one inclined end from a vertical shaft. A burner injects a flame at high temp. and velocity at that end so that the charge is molten by a heat shock and flows into the heating chamber. Contact with the hot walls increases the melting rate still further. Such a furnace requires a minimum of heating chamber area and of overall furnace dimensions. Independent of the type of material, a high throughput is achieved by the combination of heat shock with reciprocating rotation.

Title: Electronic model train controlling device - uses bridge circuits connected to isolated to stretches of rail to avoid collisions
IPC: A63H19/24
Filed: 1976-06-22
Abstract: The electronic device for controlling model trains uses bridge circuits connected to each of two stretches of rail (C. D) which are isolated from the rest (A). When a train reaches stretch (D) current flows from rail (B) via rail (D) to bridge (G). It is then passed via resistor (M) and transistors L and I back to the bridge C. where it is passed to the main rail (A) at point 1. This allows the train to pass to rail (C) where the current from rail (B) is passed via rail (C) to bridge H. It then passes through a diode (O) which is at a different potential to cause the transistor (N) to lead, thus cutting out the circuit in bridge (G). The current is then passed via the bridge (H) to the main rail (A) at point 1. This device ensures that a second train following close behind the first is held on rail (D) until the rail (C) is clear thus avoiding any possible collision.

Title: Electronic keyboard musical instrument - uses magnitude of key stroke to control note volume by LED photodetector circuit in which detector exposure is related to key stroke
IPC: G10H1/02
Filed: 1976-11-24
Abstract: Characteristics of the note emitted by an electronic musical instrument are varied in direct relationship to the magnitude of the key stroke. The key (2) engages a hinged beam (5) carrying a light emitting diode (11) and photo-detector (12). On the instrument frame (1) a stationary screen blocks light from LED (11) when the key is at rest position. As the key is depressed increasing levels of exposure to the LED (11) cause the photo-detector (12) to emit a correspondingly increasing signal which in turn controls the gain of respective amplification channels. A preliminary switch (9, 10) initiates the amplification circuits a zero gain upon the start of a key stroke and before effective exposure of the photo-detector.
