Abstract: 848,752. Reservoir pens. RITTER, J., and DOTTLINGER, A., [trading as RITTER, KOMM-GES., J.], and DOTTLINGER, F. Dec. 19, 1956 [Dec. 23, 1955; Feb. 23, 1956], No. 38630/56. Addition to 785,249. Class 146(3). A modification of the invention disclosed in parent Specification, comprises a modified shape of groove partly housing the  locking ball, whereby an undesired return movement of the ball is avoided. As shown in Fig. 3, the looking ball 4 is partly accommodated in a continuous groove 6 of a threaded clip retaining sleeve inserted in the pen body. The groove 6 has a deep recess 7 for locating the reservoir (not shown), in retracted position. The ball is carried by a horizontal guide groove 5, Fig. 1 (not shown), of a plunger 3. The side walls 6<SP>1</SP> 6<SP>11</SP> Fig. 3, of groove 6 are recessed to form opposing teeth offset as shown. Constricted portions 11 equal in size to the ball diameter prevent the ball rolling back into the groove portion from where it has been moved. In addition, such movement may also be prevented by the tips of the teeth forming resilient tongues, the distance between such tongues being less than the diameter of the ball and the wall 6<SP>1</SP> having towards. the bottom of the groove, a curvature sub tantially equal to the radius of the ball. Grease or viscous oil may also be introduced into the grooves 5, 6, containing the ball 4 to prevent the ball rolling backwards under its own weight. In a modification, Figs. 4 and 5 (not shown), a horizontal guide groove 5 for the ball 4 is formed in the clip retaining screw 2, while the groove 6 is formed in a plunger 3. In a further modification, Fig. 6 (not shown), the threaded clip retaining sleeve is formed in two parts 2, 12, the lower part having wedgeshaped noses 14 fitting in recesses 15 of the upper part 2.

In an electrical device, e.g. a transformer, insulated cable, or capacitor comprising alternate layers of dielectric and conductive material, the voltage at which corona first arises is increased by subjecting the device to a voltage stress exceeding the initial corona starting voltage, in an atmosphere of electronegative gas. A roll capacitor having dielectric film of e.g. polyethylene terephthalate, polycarbonate, polyolefine, fluorinated polymer, or paper has foil or metallized electrodes of aluminium, zinc, or copper and is filled with an electronegative gas, e.g. a perhalohydrocarbon; specifically octafluorocyclobutane, chloropentafluoroethane, hexafluoroethane; or sulphur hexafluoride or hexachloride; in a gas-tight container under pressure not exceeding 10 p.s.i., e.g. 3 to 5 p.s.i. Voltage from a mains frequency transformer is connected across the device, and the inception of corona is detected by a cathoderay oscillograph. Voltage is increased to exceed corona inception voltage and is maintained until corona ceases, after which it is again increased in steps until the required corona inception voltage is attained. Alternatively the voltage may be reduced to zero between each step increase, or a single voltage stress may be applied to exceed the initial corona inception voltage and held until corona ceases. The gas may be retained within the device after processing, or may be allowed to escape. Detailed examples are given.
