Patent DE-3536431-A1 (DE)
Title: Soldering of surface mounted devices (SMDs)
Inventor: SMERNOS STAUROS DR
IPC: H05K1/02
Filed: 1985-10-12
Abstract: In order to improve the functional reliability of solder points (7) between the connections of a surface mounted device, referred to as an SMD (3) for short, such as a chip mounting board consisting of ceramic, and the connections of a printed circuit board (1), consisting of glass-epoxy for example, the SMD (3) is initially firmly connected to a spacer (2) which is in the form of a platelet and whose material has a higher coefficient of expansion than the SMD (3). This arrangement, which consists of an SMD (3) and a spacer (2), is subsequently fixed on the circuit board (1) such that the connections of the SMD (3) are located above those on the circuit board (1). The electrical connection between the connections is produced by subsequent soldering. The spacer (2) results in greater solder point heights being achieved, which have an elastic behaviour in response to shear forces. <IMAGE>

Title: Apparatus for directed interference current (stray current, parasitic current) dissipation
Inventor: KANDZIORA ANTON DIPL ING
IPC: F17D5/08
Filed: 1986-03-01
Abstract: The object is to insert a current-direction-dependent element into the return conductor (1) of an interference current dissipation apparatus, which element is simpler than a polarised switch, acts continuously and is more effective and has higher performance than a rectifier cell. The solution essentially comprises using a power diode (2) as the current-direction-dependent element and connecting a controller (3) across the power diode, which controller (3) is constructed as an auxiliary DC voltage source which regulates galvanostatically or potentiostatically, it thus also being possible to dissipate from the installation (R) which is endangered by interference currents even interference currents whose voltage is less than the threshold voltage of the power diode. <IMAGE>

Title: Reciprocating compressor with starting relief and load regulation, especially for refrigerating machines
Inventor: WATTEZ JAN
IPC: F04B49/02
Filed: 1986-06-21
Abstract: For starting relief and load regulation of a reciprocating compressor, at least one valve seat plate 4 with radial outflow of the pressure agent in the direction of the piston stroke is guided movably in such a way that below the lifted valve seat plate a small annular clearance H1 is obtained, through which the cylinder pressure space in the start-up phase communicates in a throttled manner with the suction space S until the pressure in the pressure space D has built up to such an extent that the valve seat plate, because of the differential pressure, remains on its seat on the upper front surface of the cylinder sealed against the cylinder pressure space. By means of a servo control with a four-way valve 10 and membrane 5, the device can also be used for load regulation during operation of the reciprocating compressor in that the pressure difference between the pressure space D in the reciprocating compressor and the suction space S is used for controlled lifting of the valve seat plate 4 and thus for deactivating one or more cylinders. Sucking in of oil at the oil pan of the reciprocating compressor, resulting in slugging in the valve, is avoided. <IMAGE>

Patent DE-3633001-A1 (DE)
Title: Steerable ski
Inventor: REINHARDT THOMAS
IPC: A63C5/00
Filed: 1986-09-29
Abstract: The subject of the invention is a ski which makes it easier for the skier to effect changes in direction, since the ski consists per se of two short travelling skis arranged one behind the other which can be steered from the control bridge - the connection between the two travelling skis. The travelling skis are steered by loading the control bridges (one per foot) on the right- or left-hand side, the joints transmitting this loading to the travelling skis in a manner such that the unilateral edge pressure of the control bridge is transmitted on the one hand to a steering deflection and on the other hand, also, to a tilting of the travelling skis onto their edges. This force transmission mechanism provided by the joints can be variably set: with equal unilateral pressure on the control bridge, a greater or lesser degree of steering deflection and, consequently, a lesser or greater degree of tilting on edge, depending on individual requirements. In addition, as a result of the variably adjustable length of the ski per se, the inclination of the control bridge and the selection of different control bridges with a single ski provide a broad range of possibilities for the skier to adapt to terrain, snow conditions or his skiing ability.
