Abstract: An apparatus and system for a combination space and water heater including a controller device and a method for control. The controller device is a self-contained system that can be added to, or in combination with, existing water heaters and hydronic air heating systems using standard plumbing connections, and provides a potable water system without any need of an intermediary heat exchanger. The controller device automatically monitors a heating capacity of the water heater and the hydronic heating coil over time, and correlates measured heating loads with one or more environmental temperatures, thermostats, user settings, and/or a supplemental heating system.

Abstract: An annular member (20?) intended for a braking device (16?) in the form of a multiple disk brake. The annular member includes a first portion which forms a part of a brake housing of the braking device and a second portion which forms a pressure surface for the disks in the braking device. The invention also relates to an arrangement for driving a wheel of a vehicle including the annular member.

Abstract: A device for displacing an object a certain distance is disclosed. In one particular context, the device may be used in a brake piston. The device features a driving member and an interconnecting member located between the driving member and the object being driven (e.g., the brake piston). The driving member and the interconnecting member form a friction joint between them. The friction joint is strong enough that the driving member can push the object back to a retracted position when it is no longer being actuated, but weak enough that the interconnecting member, and hence the object, can be pushed forward relative to the driving member when the driving member reaches a maximum forward position. This lets the object (e.g., the piston) automatically adjust its non-actuated position so the same amount of fluid is required to move the piston forward as associated brake pads get thinner.

Abstract: A planet transmission (1) for a land vehicle including a planet carrier (7), which is designed for rotation and has at least one journal (8) for supporting a planet wheel (6), and a brake (2), a first set of brake discs (10) being rotationally locked to the planet carrier (7). The brake discs (10) in the first set comprise means (17) for rotationally locking the brake discs (10) directly to the planet wheel journal. A drive device for a wheel of a vehicle is also disclosed that includes the planet transmission (1), as is a brake disc (10) for the planet transmission (1).

Abstract: Method and device for displacing an object (4) a certain distance between a forward position (9) and a rearward position (10). An unit (14) is included that is displaceable between a first position (12) and a second position (13) for driving the object a distance corresponding to the distance between the first and the second position utilizing a friction joint (15) when the driving unit (14) is displaced from the first position to the second position. The friction joint is designed to enable displacement of the driving unit (14) and the object (4) relative to each another under the influence of a certain lowest force. Furthermore, the device includes a member (16) arranged to act on the driving unit (14) in a direction towards the second position (13) utilizing a spring force and a component (21) for interconnecting the driving unit (14) and the object (4). The interconnecting component (21) has a surface (22) designed to form the friction joint (15) in cooperation with a surface (23) of the driving unit.

Abstract: Method and arrangement for driving a wheel of a vehicle in which the arrangement includes a planetary gear transmission (6) which in turn has a sun gear (7) connected to a driving axle (4), a planet carrier (11) on which at least one planet gear (8) is arranged and the planet gear is also arranged in engagement with the sun gear (7), and a ring gear (9) arranged around, and also in engagement with the planet gear. The driving arrangement also includes a braking device (16) and a wheel hub (12), which hub is connected to the planet carrier (11). The braking device is adapted to brake the planet carrier relative to a static part (18) arranged outside the planet gear carrier in the radial direction. The ring gear (9) and the outer, static part (18) are constructed in one piece in the form of an annular member (20).
