Patent NL-7515062-A (NL)
Title: Injection mould - ith movable side and top members has automatic degating and sprue removal device
IPC: B29C45/33
Filed: 1975-12-24
Abstract: Injection mould having laterally openable side mould members which define open-ended mould cavity, base member and top closing member with sprue and runner passages. Automatic degating and sprue removal device consists of base mounted core pin which becomes anchored in the solidified sprue. Similar pins become anchored in individual runners. Opening movement of the top member causes the runners to break away at the gates and then pulls sprue and runners from the top member. Used esp. for moulding multiple articles with irregular shaped bottoms. Clean removal of sprue and runners during removal from the mould avoids subsequent manual work. The device avoids difficulty of operating with ejector pins on the irregular shaped bottoms. It is easier to change a machine for moulding different parts.

Patent NL-7708673-A (NL)
Title: Humidification unit coupled with an air heater - includes steam generating reservoir in exhaust flue and balancing arm level control
IPC: G05D22/02
Filed: 1977-08-04
Abstract: Air is heated and humidified by means of a heat exchanger through the other side of which the air passes whilst hot combustion gases from a burner pass through the other side. The exhaust gases from the air heater pass through a second chamber contg. a water reservoir, the heat from the gases evaporating the water in the reservoir which then passes as steam into the conditioned. air. The reservoir is fixed to a lever the fulcrum of which is a knife edge situated outside the exhaust gas chamber. The water feed is controlled by means of a solenoid valve activated by a hygrostat placed in the conditioned space. An adjustable spring holds the outer end of the lever so that the weight of the water in the reservoir acts against the spring. At a present movement of the lever, a microswitch is operated which is in series with the hygrostat. The lever arrangement thus ensures that the reservoir is not overfilled. Pref. the feed pipe to the reservoir comprises the lever. A flexible seal, esp. a silicone rubber, prevents the passage of combustion products around the pipe where it passes through the walls of the chamber.

Patent NL-8503400-A (NL)
IPC: H04L65/00
Filed: 1985-12-10
Abstract: A master station communicates with the main network, whilst a set of mobile or fixed sub stations of voice or data users share the channel using time division multiplexing. The number of time division channels available depends on the quality of the transmission links, power and modulation index. The rate of errors is detected to maintain a specified condition of operation. When all available channels are occupied a busy signal is transmitted by the master station. The effect of multiplexing on the sub-links gives apparent simultaneous bidirectional transmission.
