Abstract: At least one example embodiment provides a non-combustible smoking system or kit, comprising: a cartridge having a first end and a second end; and a tobacco containing section having a third end and a fourth end. The cartridge includes: a pre-vapor formulation reservoir element and a pre-vapor heating element coupled to the pre-vapor formulation reservoir element. The tobacco containing section includes a tobacco housing and a tobacco heating element. The first end of the cartridge is configured to be connected to the fourth end of the tobacco containing section, and the second end of the cartridge is configured to be connected to the third end of the tobacco containing section.

Abstract: A scroll machine has a fluid path which is defined by two components of the scroll machine. The fluid path extends between a discharge pressure zone and a suction pressure zone of the scroll machine. The scroll machine further includes a biasing member which biases one of the two components away from the other of the two components to open the fluid path when the scroll machine is not operating. The effect of the biasing member is overcome by several revolutions of the scroll machine by centrifugal force in one embodiment and fluid pressure in another embodiment.

Abstract: A scroll machine has a first scroll member and a second scroll member. The end plates of at least one of the scroll members is only machined in the area which interfaces with the wrap tip of the opposing scroll member. A clearance gap is maintained everywhere else in order to ensure sealing occurs.

Abstract: A motor spacer is disclosed which is well suited for use in securely fitting a motor stator of a first diameter within a housing of a greater diameter which thus avoids the need to provide more costly stepped type housings to accommodate both motor and driven apparatus. The motor spacer is particularly well suited for use in connection with hermetic motor compressors in those applications in which it is desired to utilize a shell diameter greater than that of the motor stator yet still support the motor by the outer shell. Because the motor spacer is somewhat flexible, it facilitates simultaneous assembly of the motor stator to the spacer and the spacer within the outer shell while also accommodating a wider range of tolerances between these components.

Abstract: The disclosure describes a scroll compressor which incorporates a spring biased floating seal to facilitate the start-up for the compressor. The spring biased floating seal opens a discharge to suction leakage path before and during start-up for the compressor. After a few revolutions of the scrolls of the compressor the floating seal is biased against the load of the spring to close the leakage path due to pressurized working fluid of the compressor working against the biasing of the springs.

Abstract: Disclosed are several embodiments of a stopping device operable between the drive shaft and/or orbiting scroll of a scroll compressor and a fixed wall forming part of the compressor, for the purposes of automatically engaging the wall upon reverse operation of the compressor to thereby quickly stop such reverse operation. Damage to the compressor in the event of powered reverse is also prevented, either by permitting the machine to run free or by quickly stopping it. Also disclosed are several ways to facilitate start-up with weak motors.
