Title: Heat recoverer for ventilation system - has metal rectangular sheets forming chicane type air path
IPC: F28D9/00
Filed: 1975-01-10
Abstract: The exchanger recovers the heat lost by the air discharged from a ventilation system and uses it to heat the fresh air introduced, working on the cross-flow principle with the air currents flowing in opposite directions in parallel passages which do not communicate with each other. It comprises modular metallic components formed by rectangular sheets with two adjacent edges bent in one direction from the plane of the sheet and two others in the opposite direction. The sheets are assembled together by means of their bent edges so that each one occupies a position inverted 180 deg. in relation to its neighbour. This is series of pockets are formed, turning in alternate directions so as to constitute the air passages.

Patent CH-692383-A5 (CH)
Inventor: BADER CHRISTOPHERUS
IPC: B29C45/77
Filed: 1997-09-16
Abstract: The times(t1-t4) representing the time from the start of filling of each cavity(K1-K4) to reaching a reference pressure(pR) inside each cavity are measured, the reference pressure being above the pressure at the end of the filling stage, but below the lowest maximum pressure in a cavity. The temperatures in the hot runners to each cavity are then individually controlled to reduce the differences between measured time periods. A pressure/time integral is created for each cavity over a predetermined time period, which begins at the latest at the change-over point of the first filled cavity(K1) and ends between the change-over point of the last filled cavity(K2) and the point at which maximum pressure is reached. The integral is then additionally used for controlling hot runner temperature. Maximum pressure in each cavity is recorded and used additionally for controlling the hot runner temperatures. An imaginary mean value may also be created from the recorded time integrals or maximum pressures for each cavity, the differences between recorded and the imaginary values are formed and used to control the hot runner temperatures. A preferred way of reducing the filling time differences is to reduce the temperature in the first filled cavity(K1) in steps and increase it in the last filled cavity(K2). The change-over point for each cavity is determined automatically.
