Patent number: 5561272Abstract: A sleeve head for a cable sleeve has a plurality of conically-shaped cable introduction openings which are divided in a longitudinal direction and receive conical seal elements. The sleeve head is composed of a central part and a corresponding annular part, wherein each of the cable introduction openings are arranged in a parting surface between the two parts. The parting line between the central part and the annular part can, for example, be carried out in a polygon shape with the cable introduction openings being arranged in the corners of this shape. Expediently, a single coherent-shaped seal part is employed which has both annular seal elements for each of the cable introduction openings and a sealing insert that extends between the cable introduction openings.Type: GrantFiled: August 4, 1994Date of Patent: October 1, 1996Assignee: Siemens AktiengesellschaftInventors: Dieter Kunze, Dieter Kreutz

Patent number: 5504276Abstract: The invention is directed to a cable introduction seal, having a conically fashioned annular seal of elastic material pressed against the likewise conically fashioned introduction opening. The pressing of the annular seal ensues with the assistance of a pressure element in axial direction. The annular seal is preferably provided with a longitudinally proceeding slot, so that it can also be employed on uncut cables.Type: GrantFiled: June 7, 1994Date of Patent: April 2, 1996Assignee: Siemens AktiengesellschaftInventor: Dieter Kunze

Patent number: 5502282Abstract: A sleeve head for a cable sleeve having a seal insert of elastic material and having pressure-producing elements, preferably screws for compressing the seal insert. The cable sleeve is conically expanded in the introduction region into which an initially adapted, conical seal insert is introduced. After introduction of the cables, pressure is generated on the seal insert in axial direction with the pressure-producing elements. As a consequence of the conical fashioning at the circumference of the cable sleeve, a radial compression of the elastic material of the seal insert ensues, and a sealing ensues as a result thereof. Cable clamp devices aligned with the cable introduction openings are provided in the inside of the cable sleeve.Type: GrantFiled: June 7, 1994Date of Patent: March 26, 1996Assignee: Siemens AktiengesellschaftInventor: Dieter Kunze

Patent number: 5335018Abstract: A digital phase-locked loop (PLL) which responds to a square-wave input signal of on expected frequency f.sub.E and comprises a change-over switch which is switched in response to square-wave signals or different frequencies and precedes a main divider operating with a divisor D and which produces the output signal of the phase-locked loop. The change-over switch is activated as a function of the output signal and the input signal. In order to provide symmetrical locking in of the phase-locked loop and a small capture-and-hold range, the change-over switch is switched between a first square-wave signal of the frequency f.sub.1, a second square-wave signal of the second frequency f.sub.2 and a third square-wave signal of the frequency f.sub.3, in which:f.sub.1 .multidot.1/D=f.sub.Eandk.multidot.f.sub.1 =f.sub.2 +(k-1).multidot.f.sub.3,A switching logic is provided which controls the change-over switch in such that it is switched to the signal of the first frequency f.sub.Type: GrantFiled: October 25, 1993Date of Patent: August 2, 1994Assignee: U.S. Philips CorporationInventors: Ulrich Mohlmann, Gerd Onken, Dieter Kunze, Jorg Wolber

Apparatus and method for introducing a cable-like element into a pipe and elements suitable therefor
Patent number: 5011332Abstract: A method and apparatus for the promoting movement of a cable-like element in a selected direction in a pipe with the assistance of a flowing agent moving in the selected direction in the pipe include the use of profiles arranged on the external surface of the cable-like element to produce turbulence which promotes co-movement of the cable-like element in the pipe, together with the flowing agent in the selected direction. A number of different turbulence generating flow promoting structures for the profiles are disclosed.Type: GrantFiled: November 3, 1989Date of Patent: April 30, 1991Assignee: Siemens AktiengesellschaftInventors: Dieter Kunze, Wolfgang Giebel -
Patent number: 4892443Abstract: A cable plow having a chassis with a pivot arm having a first end pivotably connected to the chassis and a second end pivotably connected to a plow element characterized by an arrangement extending between the plow element and the pivot arm to resist pivoting of the plow element from a desired or rated plowing position in response to increased forces applied on the element. Preferably, the chassis is constructed as a sled which is adapted for plowing or laying cable on either land or beneath the water's surface.Type: GrantFiled: July 1, 1988Date of Patent: January 9, 1990Assignee: Siemens AktiengesellschaftInventors: Dieter Kunze, Peter Lancier

Patent number: 4865893Abstract: A sleeve tube which has a single, longitudinal division or opening and is movable from a spread condition to a closed condition to form a circle of a first radius and coact with end sealing elements to form a cable sleeve. In the spread condition, the sleeve has a continually changing curvature, with the radius of curvature of the sleeve at a point opposite the opening being on a maximum radius of curvature and the radius of curvature continuing decrease as the openings are approached so that when the sleeve is moved to the closed position, all portions of the sleeve are deformed a slight amount from the relaxed, opened position to the closed position. Thus, a uniform closing pressure can be obtained on the entire periphery of each of the end sealing members.Type: GrantFiled: December 9, 1987Date of Patent: September 12, 1989Assignee: Siemens AktiengesellschaftInventors: Dieter Kunze, Ernst Bachel
