Filed: 1943-01-25
Abstract: 560,650. Soap. WILLIAMS, W. P. (Procter & Gamble Co.). Jan. 25, 1943, No. 1236. [Class 73] In the manufacture of soap bars.which may readily be broken in two, a cleavage plane is formed by a plurality of perforations a aligned across the smaller dimension of the face of the bar about midway of its length, the bar being afterwards stamped into final form in the usual manner. The perforations may be made by knife blades 2, Fig. 3, or by needles, and may be made from both faces of the bar towards the middle. In order that a bar may be discarded should a broken-off blade be embedded in it, an inspection of the blades is made after each perforating operation. This is done by throwing a narrow pencil of light 1 on to each blade just short of its tip, and mounting an electric eye 3 in a position to receive the light beam if the blade be broken or missing, this eye actuating a relay-which stops the machine. When needles are used, a small spring-pressed rod presses against each needle and is adapted to move across the path of the needle should this be broken or missing, actuating a switch to cut off the current and stop the machine.

Abstract: 547,167. Cable joints; cable sleeves and like end constructions. STANDARD TELEPHONES & CABLES, Ltd., and LEE, E. C. Feb. 14, 1941, No. 2027. [Classes 36 and 38 (i)] A joint or termination for a cable of the type having a flexible impermeable wall compressed on to the insulation by external gas pressure has a sheath surrounding the insulation of the joint &c. sealed to the flexible wall by a wiped or soldered joint which is isolated from the gas pressure space by a space at substantially atmospheric pressure. Where the joint insulation is not under pressure the joint sheath 6, Fig. 1, is bolted to flanges 8, 9 and to a brass sleeve 7 which is sealed to the outer sheath 3 of the cable 4 to enclose the gas pressure space 2 surrounding the flexible wall 1. The flanges 8, 9 are wiped to the wall 1 by joints 11, 12, and between the flanges and the wall 1 is a space 14 connected to the atmosphere by radial grooves formed in the adjacent faces of the flanges 8, 9. Any gas leaking through the joint 12 thus escapes to the atmosphere and the joint 11 is isolated from the pressure space. The escape grooves may be sealed against low gas pressure and the yielding of the seal may give an alarm. If the joint insulation is to be placed under gas pressure similarly to that of the cable it is surrounded by a flexible and impermeable sheath 16 surrounded by an outer sheath 20 to form the gas pressure space 21 closed at its end by a collar 22. The sheath 16 and wall 1 are connected by a sleeve 17 with wiped joints 18, 19, both of which are isolated from the pressure space 2 by a sleeve 23 mounted in a collar 25 between which and the collar 22 are radial grooves 30 connecting to the atmosphere the space in which the joints 18, 19 lie. A pipe 29 affords communication between the gas pressure spaces 2 and 21.
