Title: Clock controlled central heating regulator - has a supplementary electronic timer for periods of increased heat output
Inventor: RONNERHOLM S
IPC: G05D23/19
Filed: 1974-04-24
Abstract: A central heating system is switched periodically by a clock between day and night time levels of heat output. The supplementary electronic timer is intended to raise the heat output level for a predetermined interval in order to provide a rapid rise of room temperature from the lower to the higher value. The circuits consist of a probe which is connected to the clock and receives a start signal at the changeover time. The probe switches on an oscillator which feeds a seven stage binary counter via an amplifier. An output signal from the counter is fed into the temperature regulator to raise the temperature called for. After a preset time the oscillator switches off, the counter resets to zero and the temperature regulator reverts to normal operation.

Title: Continuous dryer with two chambers - and perforated shaker-table for mfr of fish meal and other prods
IPC: F26B3/06
Filed: 1974-07-11
Abstract: Continuous dryer, for more or less finely divided prods. is partic. intended for drying previously cooked and pressed fish scraps for the mfr. of fish meal. It can also be used for making flour from feathers and leather, for the drying of fodder or for any other prod. where the water content must be reduced. The raw matl. is fed into the plant by the elevator, which may be of the endless screw type, into the cooker; this can also be of the screw type in a double-walled casing. The prod. is evacuated by conveyor to an independent press, to reduce the moisture content. The pressed prod. passes into the first chamber of the dryer, through the chute, on to the shaking-table, which is supported independently of the body of the dryer. The heat is generated by a fuel burner. The hot gases pass through the heat exchanger on their way to the first chamber; heated air from the exchanger passes into the second chamber. They traverse the prod. to be dried through the perforations of the shaking table; as the particles dry they are picked up by the current of air and entrained towards the cyclone where they collect at the base. After passage through the air-trap they are evacuated by the conveyor for grinding and sacking. The dryer has the min. of moving parts; it can therefore be of a light, non-complicated type of construction. As the particles dry they are selected pneumatically so the prod. only remains in the dryer for the min. amt. of time.
