Abstract: In an electric motor for oil burners, the stator lamination stack (2) and the excitation winding (3) arranged thereon are largely surrounded with plastic (8). For better extraction of the motor heat loss, the plastic surround (8) of the stator (1) connects an essentially hollow metal part (10), which holds the B-side bearing (6) of the rotor shaft (5) and forms the pump adaptor (9), to an A-side metal flange (11), which is used as a motor attachment to the oil burner fan, and to which, at the same time, is attached an end plate (13), which holds the A-side bearing (7) of the rotor shaft (5) and is fitted when the motor is installed. The heat extraction can furthermore be advantageously influenced if the B-side metal part (10) and/or the A-side metal flange (11) are brought forward so far to the stator (1) that they are located in direct contact with the stator lamination stack (2). Moreover, filling material which increases the thermal conductivity of the plastic surround (8) of the stator (1) can be enclosed in it for the same purpose, and the plastic surround (8) can penetrate through rivet holes (16) provided in the stator lamination stack (2). <IMAGE>

Abstract: A control apparatus for antisurge protection of a dynamic compressor including a junction of a closed antisurge loop with a surge limit computing module and a two mode controller with a relay backup system with deviation alarms is characterized in operation in that during a slow disturbance, the two mode controller provides modulated antisurge protection by opening a relief valve. If the operating point of the compressor crosses the surge control line and during a dangerously fast disturbance, the relay backup system (119) provides antisurge protaction if a preestablished deviation of the operating point from the surge control line appears. The relay backup system (119) opens the relief valve (107) very quickly. When the relief valve (107) is so opened, the process of the user (106) of fluid from the compressor (101) is compensated by increasing the performance of the compressor (101) to maintain pressure or flow rate. Then the relay system (119) closes the relief valve (107) exponentially, which prevents a dangerous deviation of the operating point from the surge control line. In time, the surge limit line may change so that the surge control line is no longer correctly ( placed. If under such circumstances surge appears, then the backup relay system (119) opens the relief velve (107) very fast, closes it exponentially and changes the position of surge control line.

Abstract: A sensor (1), through which gas, e.g. air, flows contains a valve (5) whose degree of opening is determined by the difference in pressure before (P1) and after (P2) the valve (5), and which is fixed to a displacement- voltage converter (6) for electrical output indicating valve opening degree and also to a slidable rod (2) with an end connecting to a pressure chamber (7). Liq. at constant pressure (pf) is supplied to the pressure chamber (7) and also to a 1st chamber (16) of a pressure regulator (9). This 1st chamber is separated from a 2nd chamber (17) filled with the same gas that flows through the sensor (1) by a spring-loaded bellows (18) which controls degree of opening of a ball valve (23) leading from the 1st chamber to a liq. reservoir. Compensation for gas temp. or density is achieved rapidly with simple construction, making the detector useful as a constant flow regulator, e.g. for an i.c. engine fuel-air injection system.

Abstract: When moulding a multi-coloured article on a multistation injection moulding machine, the mould is shaped so that the element (24) moulded at the first station includes a separation rib (26) adapted to engage with the surface of one mould half (32) at the second station to form separate mould cavities for the second and third materials (12 and 14). A respective check rib (28, 30) is formed on each side of the separation rib (26), each check rib projecting so as to leave a clearance between such rib and the surface of said mould half (32). The check ribs (28, 30) ensure that the second and third plastics materials reach the separation rib (26) as a uniform front and at a reduced pressure, with reduced material dwell against the separation rib (26) at high temperature. A similar check rib is provided adjacent to the boundary of any zone in which the element (24) moulded at the first station extends through the entire thickness of the article.
