Title: Programmable cooker for edible pastes
Inventor: TAVANI ANTONIO
IPC: A47J/
Filed: 1984-11-28
Granted: 1988-12-30
Abstract: The character pattern generating system has a character data memory for storing co-ordinate data representing co-ordinates of a base line at a centre of a character component and for storing local outline data representing the outline of the respective character component at each co-ordinate. The system responds to a character code received from an external source for reading out the co-ordinate data and the local outline data. Outline data is generated on the basis of the co-ordinate data and the local outline data and for generating character bit pattern data from the outline data. Storing the character pattern in this form allows easy scaling of the character shape, by lengthening or shortening to the base lines.

Abstract: This invention is useful to lifting and haulage transport, specifically test point distribution that is used for load measurement, and particularly to electronic dynamometer with wireless transmittance of measurements to an indicator. Its objective is to expand functional capacities of the electronic dynamometer while reducing its weight and dimensions, as well as costs.The present dynamometer basic flow chart, which is shown in Fig.1, contains a tensiometric load converter (1) with an annular power measuring element, a weight measuring block (A) containing analogue-to-digital converter (2), a microprocessor (3), and a transmitter (4). It also consists of a control board (B) containing a receiver (8), a microprocessor (10) linked with non-volatile memory (13) and a service keyboard (12), as well as a weight indicator (11). The transmitter (4) is characteristic of its built-in device for three-band coding of measurements with the help of advanced frequency and transmission length of information signal to 0.2 seconds. The weight-measuring block (A) is fixed to the body of the load converter (1), and the power-measuring element of the converter is designed in the shape of a ring on the interior surface of which tensoresistors (16) have been stuck in mutually perpendicular directions of the plates of the element. The signal measured from the load converter (1) goes to the analogue-to-digital converter (2) and microprocessor (3), and then is passed on to the transmitter (4). The receiver (8) of the control board (B) passes the demodulated signal to the board microprocessor (10) and the weight indicator.<IMAGE>

Abstract: This invention relates to a boiler installation for the combustion of solid fuels, for example forest waste material in the form of e.g. bark and or chips, peat pellets, coal etc., which installation comprises a furnace located in connection to a heat medium portion and a grate means located in the furnace, which grate means feeds fuel from a fuel charge opening through the furnace while the fuel is being combusted, from which furnace the flue gases flow to the heat medium portion and continue to a chimney, and at least one intake for controlled supply of combustion air in the form of at least primary and secondary combustion air. In order to improve the efficiency degree of such boiler installations and to render possible efficient and complete combustion of forest waste material and other biologic fuels, which may have a high moisture content, the rear portion of the grate means (4) of the boiler installation, seen in the direction of movement, is located outside of the furnace space (1) proper but connected thereto for forming a zone in connection to the charge opening (5 for a certain drying of the fuel before it is fed into the furnace (1) by the grate, and comprises transverse dogs (9) running on a grate plane for advancing the fuel through the furnace (1), which grate plane is located above means (25,26) for the supply of the primary combustion air from below to the fuel, and below the air intakes (29) for the secondary combustion air.
