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: The present disclosure provides systems and methods for in-line thermal flattening and enameling of steel sheets. The systems and methods include an in-line thermal flattening of a feed stock steel sheet and a subsequent enamel coating of the steel sheet. The resulting enamel coated steel sheet has improved flatness compared with other coated steel sheets that are enamel coated but do not undergo the in-line thermal flattening. The systems and methods allow the use of less expensive source materials without sacrificing quality in the finished enameled product.

Abstract: Provided is a snow thrower impeller assembly (24) that defines a mounting slot (84) for a wiper (70). The wiper includes a wiper portion (86) that slides into the mounting slot to mount the wiper to the impeller (54). The wiper contacts an interior wall (56) of an associated impeller housing during rotational operation of the impeller in order to limit a gap (74) between an impeller blade (66) and the interior wall. The wiper can move radially inward and outward to remain in contact with the interior wall without input from the operator. Another embodiment of the impeller assembly includes impeller blades with a first portion (116) and a second portion (118). The second portion extends at a non-zero angle from the first blade portion of the impeller blade. Methods of improving the efficiency of the snow thrower are also provided.

Abstract: A method of managing a clinical trial where the clinical trial involves a follow-on biological (FOB) substance, the method comprising: receiving subject data at a computer system as the subject data becomes available, the subject data indicating effects of the administration of the FOB substance in the clinical trial; storing the subject data in a database; and making coded data electronically available to an authorised independent monitor, the coded data being based on the subject data and indicating effects of the administration of the FOB substance in the clinical trial but having subject-identifying information omitted therefrom, wherein the coded data is made available once the subject data is stored in the database.

Abstract: A ZTR lawnmower having first and second drive wheels and first and second control levers to control the direction and speed of rotation of the first and second drive wheels. The lawnmower further includes a park brake system operatively interconnected with at least one of the drive wheels, and an interlock mechanism interfacing with the parking system. The park brake interlock mechanism includes a parking brake handle movable between an engaged position and a disengaged position to cause the park brake system to respectively resist and not resist rotation of the at least one drive wheel.

Abstract: A cooling system for an engine of a lawnmower. The engine has a muffler through which exhaust gases exit the engine and is cooled by a liquid coolant. The cooling system includes a heat exchanger operatively connected to the engine to receive the liquid coolant from the engine at a first temperature and return the liquid coolant to the engine at a lower temperature. A fan mounted above the heat exchanger is operable to draw or pull an air flow in a standard direction upward through the heat exchanger. The heat exchanger and fan are oriented in an inclined orientation such that the air flow is directed upward and away from the operator station of the lawnmower. The cooling system also has a generally tubular baffle surrounding the muffler at least partially isolating the engine from heat radiating from the muffler.
