Title: Mobile communications network
Inventor: Zaid Al-Daher
IPC: H04W72/04
Filed: 2016-05-31
Abstract: A mobile terminal being served over a broadcast or multicast network sends information about the signal quality to the network. The signal quality is compared to a threshold, said threshold being varied according to a measure of loading of the network, and the mobile terminal may be switched to unicast as a result. This is directed for use in LTE networks using eMBMS and MBSFN, and is intended to prevent service disruption when a terminal moves between MBSFN areas 22, 24, 26 (transition 230) or into a reserved cell 226 which only supports unicast (transition 232). The measure of loading may be radio resource usage. The method may further comprise instructing the mobile terminal, once operating in unicast mode, to switch between base station transceivers after comparing the serving signal quality to a second threshold. This threshold may similarly be varied according to network loading. Embodiments using both sectored and un-sectored cells are disclosed.

Title: A motor vehicle drawer assembly
Inventor: James Nicholas Murray
IPC: B60R11/00
Filed: 2016-07-27
Abstract: A motor vehicle drawer assembly (20) is disclosed having a slideable drawer (22) and a moveable platen (40) possibly housed in a casing/support structure (21). The drawer (22) and/or the platen (40) both have overlying compressible members (24, 43), which may be made from foam and are used to restrain from movement an item placed in the drawer (22) when the drawer (22) is in a closed position. Movement of the drawer (22) to the closed position causes the platen (40) to move towards the drawer (22) so as to clamp any item resting on the drawer (22) thereby restraining movement of the item but not until the drawer (22) approaches the closed position. The use of a clamping mechanism (28, 36) that only allows for movement of the platen (40) towards the drawer (22) when the drawer (22) approaches the closed position prevents the platen (40) from interfering with stowing of the item.

Title: Pitch retainer
Inventor: MAREK JAKUBASZEK
IPC: F16H57/12
Filed: 2018-06-26
Abstract: The pitch drive system of a wind turbine includes a ring gear 3 connected to a turbine blade and a pitch drive comprising a motor and a pinion 4. The pinion meshes with the ring gear so that a pitch of a turbine blade may be adjusted by rotation of the motor. The anti-backlash mechanism comprises an anti-backlash gear 1 and an energy storage means 8 mounted on the ring gear and connected to the anti-backlash gear. Rotation of the ring gear by the pitch drive system causes the anti-backlash mechanism to receive energy from, or transmit energy to, the energy storage means, thereby reducing impact between flanks of the ring gear and the pinion. The energy storage means may comprise a resilient member such as a spring and a piston, whereby the piston can be driven by a rack 6 that is meshed with the anti-backlash gear in order to compress or release the spring. The anti-backlash gear can then be urged against the flanks of the ring gear by the bias force of the spring to take-up any slack or clearance between the ring gear teeth and the teeth of the motor pinion 4.
