Title: Dip-soldering small electronic components esp. chip capacitors - using circulation of molten solder to ensure sound joints
Inventor: KOEPPE WOLFGANG
IPC: H05K3/34
Filed: 1973-09-18
Abstract: Small components to be soldered are immersed vertically at a controlled speed in a bath of molten tin, the tin flowing in a direction at 90 degrees to the immersion-direction and at a speed below the immersion speed of the substrate carrying the components. The prefd. device for carrying out the process consists of a reservoir from which molten tin is pumped along a channel in which the substrates are immersed, the channel being several times longer than the substrate and contg. a sill which controls the height of the Sn. Specif., the substrates are suspended from a horizontal, 8-point star mounted on a vertical cylinder so the substrates can be lowered into the bath at a point at least twice their length from the sill; after being lifted out of the bath, the star is rotated 45 degrees and the next substrate immersed. Used for mass prodn. dip soldering of e.g. chip capacitors 1mm thick on ceramic substrates, 40 x 10 mm. Uniform soldering of the joint is achieved without defects arising due to the shielding of part of the joint during immersion.

Title: Smoke vent cover with horizontal hinges - has spring loaded hinge for preventing excessive shock loads on hinge on opening
Inventor: HOEGEDAL SVEN ANDERS
IPC: E05D1/04
Filed: 1974-10-09

Title: Support plate for disc brake pad - has vee-shaped radial extension for sliding location in brake body
Inventor: COURBOT PIERRE
IPC: F16D69/00
Filed: 1974-10-30
Abstract: To reduce the reaction forces set up in the brake pad location, the brake body is placed radially outside the brake disc. VEE-shaped slots in the brake body locate the similarly shaped extensions of the pad support plates so that they are free to move axially towards the brake disc. Hydraulic brake cylinders provide the braking force applied to the two brake pads. With suitably dimensioned VEE-location the reaction forces reach a minimum value so that a reduced overall brake size and weight is possible. In a preferred embodiment the tangent of the braking force is equal to the sector from the middle point of the second edge of the first end of the T shaped extension to the line reached by the tangential force.
