[Also in Division H1] In an electric cable having a conductor core 52 and a metallic shield 55 a plastics jacket 53 or 57 is securely bonded to at least one of the surfaces of the metallic shield through an intermediate boundary layer 54 or 56 of a thermoplastic polymer of a major proportion by weight of ethylene and a minor proportion of an ethylenically unsaturated carboxylic acid, the bond being substantially co-extensive with the common surface of contact of the shield and jacket. The bond is made by applying the copolymer of ethylene and unsaturated carboxylic acid, such as acrylic acid to both sides of the shield 55 formed by a longitudinally folded copper or aluminium tape and extruding onto it an outer sheathing 57, e.g. cf polyethylene. In this way bonds are obtained at 56 and/or 54. The submarine cable shown has a tensile steel core 51. The metal parts can be coated with the adhesive polymer by melt extrusion, powder spraying or by passing the heated part through a fluidized polymer powder bed, casting from a solvent solution, or fusion of a thin solid film of the polymer on the part. The invention can be applied to various types of power or communication cables (Figs. 1-4 not shown) including cables with coducting plastics sheathing (Fig. 6, not shown), the conducting material being acetylene black. Various examples of carboxylic acid are given and the adhesive polymer may be a random copolymer of ethylene.

An expanding gear-wheel comprises segments which each have a tooth extension entering a recess in a tooth part of the adjoining segment, the segments being displaceable peripherally and radially to vary the penetration of the extension into the recess and hence vary the total number of teeth. As shown an internally toothed ring gear has segments 10-12 supported by leaf springs 18 and tubular springs 20 from a load bearing annulus 19. Each segment has at one end an extension 14 entering a recess 15 provided in the adjacent end of the next segment, the separation of each pair of segments being adjusted by a radial shaft 28 engaged in a threaded bore in the annulus 19 and passing through a hole 26 in an extension 17 of one segment and carrying a cam 29 engaging an aperture 27 in the other segment. The outer end of the shaft 28 is provided with a capstan 30 selectively engageable with pins 31, 32 which can be projected into the path of the capstan 30 as the annulus 19 and ring gear rotate to shift the cam 29 between two end positions and thus adjust the segments between a position in which the projection 14 fully enters the recess 15 and a position displaced therefrom by one or more teeth to alter the effective number of teeth in the ring gear. The radial displacement of the cam 29 due to the threaded connection of the shaft and the annulus 19 is arranged to match the radial shift of the segments as the ring is expanded and contracted. In a modification instead of a cyclometer type drive provided by the capstan, the shaft 28 terminates inside the thickness of the annulus 19 and is formed with a bevel wheel meshing a bevel segment mounted in a radial plane in the annulus 19 and having its ends projecting therefrom and engageable with peripherally arranged cams which are selectively shiftable towards the periphery of the annulus to adjust the bevel segment and hence the cam 29 and ring gear segments. In this modification only two segments are provided. The expanding gear need not be a ring gear, it could be externally toothed or facially toothed or be a bevel wheel.

Filed: 1938-12-23
Abstract: 523,118. Photographic cameras combined with flashlights. SCHWARTZ, K. Dec. 23, 1938, No. 37449. [Class 98 (i)] [Also in Groups XXXVII and XXI] Each time the shutter of a camera is operated, a circuit is completed to an electromagnet 3 which moves a selector switch 7 on one step, thereby causing the successive ignition of flashlight lamps 31, 32, 33. In the form shown in Fig. 1, the magnet 3 attracts a core 4 and pawl 6 which operates a rotary switch 7 which is held against return movement by another pawl 9. When the three flash lamps 31-33 have all been used the case carrying them is unplugged from the switch box and projections 17 by engaging projections 18 release the pawls 6, 7 so that the switch 7 returns to its original position. A new set of lamps can then be inserted. In a modification, Fig. 2, the switch is moved step by step by a spring 21, the electromagnet 3, which cooperates with an escapement 22, serving only to release the switch. When the shutter is operated contacts 51, 53 are bridged and a circuit completed through contact 41 to lamp 31 and another circuit completed to the electromagnet 3 which attracts its armature. The escapement is so designed that this movement does not release the switch 7. Only when the circuit is broken again does the switch 7 move on to its next contact and prepare the circuit for igniting the next lamp. When the lamp case is unplugged a plunger 27 rises under the action of a spring 24 and a lever 25 by engaging a stop 26 resets switch 7 to its original position. In a further modification Fig. 5 (not shown) a number of devices, each carrying three lamps may be plugged together and operated by a single battery contained in one of the devices. Each switch 7 has also an extra contact, so that after the three lamps of a device have been ignited, this extra contact is engaged and serves to complete a circuit to the switch in the next device.
