Title: Bearing puller
Inventor: YU MIN-CHI
IPC: B25B27/06
Filed: 2010-03-16
Abstract: The bearing puller for holding and disassembling a bearing 30 which is tightly engaged with a machine part 20 includes a fixing portion 40A, a disassembling portion 50A, a binding ring 60 and a sleeve 70. The sleeve is screwed on the fixing portion to compress the binding ring to reduce an inner diameter thereof, so as to grab and hold the bearing 30. The disassembling portion, which may be rotatably mounted on the fixing portion, can produce a displacement relative to the fixing portion to reject against the machine part or it can hit the fixing portion to produce a momentum, thereby causing a relative movement between the machine part and the bearing to disassemble the bearing. Therefore, the bearing can be disassembled rapidly without damage and reused, saving cost.

Title: A pulling torpedo for optical cable installation
Inventor: MCCOLLOCH LAURENCE RAY
IPC: G02B6/44
Filed: 2010-09-14
Abstract: A torpedo (1) is provided for use in pulling an optical communications device 35 through ducts, vents, pipes, and the like. The torpedo (1) has a mating feature formed thereon that mates with a mating feature formed on a boot 30 of an optical fibre cable 25 when the torpedo is attached to the boot. The mating feature formed on the torpedo is typically a key 40 and the mating feature formed on the boot is typically a keyway 50 having a shape that is complementary to the shape of the key. The mating of the key 40 and keyway 50 eliminate the need to use a clamping force to ensure that the grip between the torpedo and the cable will not be lost or compromised when the torpedo is being pulled. The boot (30) of the optical fibre cable may be a standard cable boot, and therefore does not need to be a specialized boot designed specifically for the purpose of attaching to a torpedo. The boot is attached in the normal manner to the strain relief device of the optical fibre cable. Consequently, pulling forces that are exerted by the torpedo on the boot are translated through the boot into the strain relief device of the cable, thereby preventing forces from being exerted on the cable that could damage it.

The synchronisation current level is greater than or equal to the minimum current required to produce a magnetic field having magnetic flux of a sufficient magnitude to synchronise the position of the magnetic rotor with the magnetic field. The applied electric current may be DC such that the rotor is brought into position with respect to the stator before rotation of the rotor begins.

Title: Slurry outlet in a gravel packing assembly
Inventor: HAMMER AARON C
IPC: E21B17/10
Filed: 2011-04-25
Abstract: An outlet member is preferably made from a hardened material and is cut from a tubular shape at an angle of preferably 5 degrees. At its upper end it is cut away so that slurry flow can exit ports in a hardened sleeve and impinge directly onto the upstream portion of the insert. The impingement changes the flow stream angle as the flow continues through a fully tubular middle segment of the insert that leads out to an elongated exit ramp whose downstream end sits preferably flush with the outer housing wall so as to protect the insert from mechanical shocks and retain the insert axially when slurry flows through it. Other external details aid in fixation when in use.
