Abstract: Method and apparatus for coating catalytic converter substrates with an exact amount of a precious metal. In the course of operation of the apparatus, a hollow substrate to be treated having opposed open ends is transferred from a starting location such that one end is lowered into a dip pan into which has been introduced a predetermined amount of slurry material containing the precious metal. With the one end immersed in the slurry, a vacuum placed on the other end of the substrate draws up the entire charge of slurry from the dip pan to coat the lower portion of the substrate. Thereafter, the substrate is raised from the dip pan. The vacuum continues to operate to cause the coating to be evenly distributed on all the interior surfaces of the substrate. Then the substrate is rotated and again lowered so that the other end is immersed in another predetermined charge of the slurry and the process is repeated. Thereupon, the substrate is again raised from the dip pan. Again, the vacuum continues to operate for a predetermined period of time to assure even distribution of the coating. Then the substrate is again rotated to its original orientation, and returned to its starting location.

Abstract: A closure for a pressurized container, such as a coolant radiator, provides overflow protection by means of a tube connecting the highest point of the container with the filler neck. The end of the tube in the filler neck is closed by a cap having a high pressure relief valve. The closure cap also contains a low pressure relief valve connected to the tube which, together with the high pressure relief valve, maintains a pressure balance in the container without substantial change in the amount of fluid therein. Both valves are connected directly to a bleed line to atmosphere or a reservoir. The tube and filler neck together serve to regulate the pressure in the container and to provide a maximum fluid level within the container.

Abstract: This invention relates to a multi-cavity valve gated injection molding system wherein a continuous flow of hydraulic fluid through the actuating mechanism provides additional cooling. A pair of hydraulic fluid lines (114, 118) are drilled in the mold back plate (12) to apply a minimum pressure differential across the cylinder chamber on one side of the piston (60). In the preferred embodiment, this pressure differential is also applied to opposite sides of a circular cooling chamber (110) extending through the cylinder (62) to provide additional cooling near a high pressure seal (70). Additional cooling is very advantageous to avoid system malfunctions and inferior product, particularly when molding high performance engineering resins at a high temperature.

Abstract: A conditioning device for an extruder (14) includes two juxtaposed, frustocylindrical, intercommunicated chambers (24-26), one chamber of which has a greater cross sectional area than the other chamber. A mixing shaft (28) centrally located within the small chamber carries a number of radially extending beaters which rotate at a speed twice that of the rotational speed of paddles mounted on a second mixing shaft (36) located in the large chamber and material introduced into the vessel is passed from side-to-side between the two chambers while being advanced along the length of the vessel. The use of relatively fast moving beaters within a small mixing chamber in combination with relatively slow moving paddles in a larger mixing chamber enables flour-like materials to be properly blended with water with both sufficient agitation and proper retention times within the vessel. In an alternate embodiment of the invention, the vessel is tiltable about an axis parallel to the longitudinal axis thereof, in order to bias the materials under the influence of gravity toward one chamber or the other and to thereby vary the residence time of the materials within the vessel and the mixing characteristics of the device.

Abstract: During the tuning of a video recorder to a television receiver, a test signal generated in the video recorder is connected to the output by means of special keys or switches or by inputting a particular code number, in order to obtain a test pattern on the screen of the television receiver which is used for adjusting the picture sharpness. The novel device is intended to simplify the tuning process for the user. For this purpose, it is checked whether a useful signal is present at the output of the receiving section (6, 7) of the video recorder (1), or not, and when there is no useful signal, the test pattern generator (7) is automatically connected to the output of the video recorder. <IMAGE>

This spring is pref. a trand of high-strength aramide fibres which is balanced by a counterweight. The swing lever turns on the pivot and can be put under tension by the strand of aramide fibres which is wound on the ratchet wheel drum with the pawl loaded by the wt. on the lever. The lever is tensioned by the cam, driven by the loom motor, which straightens the knee joint a little over dead centre.  The cam releases it by its peak and the lever imparts an impart on the shuttle as it turns clockwise.  Near the end of its path, the brake strand comes into action and decelerates the lever through a dashpot and the weight on ratchet wheel.

A transfer foil which is particularly suitable for that process has an absorption layer in the surface regions of the decorative layer, which are to be transferred onto the substrate, which absorption layer absorbs the radiation energy causing activation of the adhesive layer and activates the adhesive layer under the action of the absorbed radiation energy.
