Abstract: A non-combustible aerosol provision device for generating an aerosol from an aerosol-generating material is provided. The device includes a chamber for receiving a consumable including aerosol-generating material to enable the non-combustible aerosol provision device to generate an aerosol from the aerosol-generating material. The device further includes an adjustment mechanism to allow a user to adjust a dimension of the chamber to allow the chamber to accommodate, one at a time, each of a plurality of consumables having different sizes.

Abstract: A non-combustible aerosol provision device for generating an aerosol from aerosol-generating material included in a consumable, the non-combustible aerosol provision device having: a receptacle for receiving the consumable; and an adaptor configured to adapt the non-combustible aerosol provision device by varying an effective length of the receptacle such that each of a plurality consumables of different lengths, which are individually receivable in the receptacle, when received in the receptacle for use, protrude from the non-combustible aerosol provision device by substantially equal amounts.

Abstract: A non-combustible aerosol provision device for generating an aerosol from aerosol-generating material in a consumable is disclosed. The non-combustible aerosol provision device includes a retention apparatus configured to hold in position, one at a time, each of the plurality of consumables comprising aerosol-generating material of different sizes.

Abstract: There is described deployment apparatus and methods that may assist with efficient and/or effective deployment and/or retrieval of deployable mediums (e.g. wirelines), for example in a well. In some examples, the deployable medium, e.g. wireline, may comprise data regions provided along some or all of the length of the deployable medium, whereby the or each data region is configured store data at the deployable medium. There is also described a communication device configured to communicate with the data regions so as to read and/or write data from/to those data regions during deployment and/or retrieval of the deployable medium in a well.

Abstract: A perforating gun (50) for use in a wellbore comprises a body (52) configured to be displaced within the wellbore, and first and second charge arrangements mounted on the body (52) and configured to be detonated independently of each other. In one embodiment the body (52) is configured to be moved axially within the wellbore between detonation of the first and second charge arrangements and at least portions of the first and second charge arrangements are provided within a common axial length of the body (52).
