Title: Centraliser
Inventor: IAN KIRK
IPC: E21B17/10
Filed: 2018-11-08
Abstract: A centraliser 10 for use in centralising tubing in a bore comprises a first end collar 14, a second end collar 16 and a number of elongate strut members 18. The strut members 18 are interposed between the first and second end collars and are circumferentially arranged and spaced around the end collars. The strut members have a first and second end portions and an intermediate portion which has angled wing portions extending therefrom. The wings define a non-zero angle relative to the intermediate portion which may extend to 180 degrees i.e. they fold back on themselves; the angles may be different for each wing. The strut end portions may be bifurcated or have a single portion to connect to its collar. The wings provide relative stiffening of the intermediate portion which provides preferential strut flexing towards the end portions to optimise flexibility to pass bore restrictions whilst recovering its shape. The centraliser may be unitary or fabricated and may be selectively configurable in large and small diameters.

Title: Circuit breaker with delayed reclosing function
Inventor: Mirko Guaschino
IPC: H01H77/10
Filed: 2020-06-16
Abstract: A circuit breaker 1 comprises a rotatable contact arm 6, a supporting surface 9a,b running along a control curve, and a tension spring arrangement 10a,b having a first end C1,C2 connected to the contact arm and a second end D1,D2 slidably supported by the supporting surface (9a,b, figure 5). The tension spring pulls the contact arm towards a closed arm position in which it is separated from the second end of the tension spring. Upon an opening rotation, the contact arm contacts the second end at an intermediate arm position while the second end is at a first spring position or depression b1. Upon a further opening rotation, the contact arm pushes the second end into a second spring position b2 over a convex elevation E. The second end may be pulled into the first spring position by the tension of the spring during a closing rotation of the contact arm. The circuit breaker may comprise a rotatable switching shaft 8 as a secondary slow opening mechanism which rotates at a higher threshold current than that of the contact arm. The sliding of the second end between the two spring positions delays the reclosing time of the contact arm and allows the switching shaft to permanently open the contacts.
