The invention relates to an exhaust gas heat exchanger () with a housing (), in which a tube bundle () with multiple tubes () is held via headers (), wherein in the tubes () a first flow path for exhaust gas () and between the tubes () and the housing () a second flow path for coolant () runs, wherein the first longitudinal ends of the individual tubes () of the tube bundle () are incorporated in a first header () in a fixed manner, in particular welded or brazed. It is substantial to the invention that at least one of the tubes () is axially moveable in the region of a second longitudinal end relative to the second header () and captive therein.

A trailer hitch bumper guard that is formed from three-sided box-like apparatus mounted to the rear bumper of the towing vehicle with a fourth, open side of the apparatus which faces outward from the rear of the towing vehicle. The bottom of the box has a round hole, through which the ball of a trailer hitch may be attached. The three closed sides of the box provide protection from dents and scratches to the rear bumper of the towing vehicle if the trailer's receiver apparatus passes the ball and comes into contact with the rear portion of the bumper. A hinged cover is attached to the rearmost side of the box, and pivots upward to allow greater access to the ball hitch. During attachment, the hinged cover is placed in the open position and thus, extends the amount of protection supplied to the vehicle by the present invention. When in the lowered position, the hinged cover creates a step on which the driver can stand to gain easy access to the rear portion of the towing vehicle. The closed cover can also be secured with a padlock to provide protection from theft and unauthorized tampering with the hitch.

A portable personal floatation device for water sports such as fishing and the like is constructed of a light material such as styrofoam and has a main cross panel with an opening for a user to fit through so the floatation device surrounds the user. The device is designed to be easily accessible for the user, with a door provided on a side panel. The central opening in the main panel of the device accommodates the occupant to carry the device and wade into the water, and as the device begins to float, the occupant may sit on the main panel of the device.

A portable personal floatation device for water sports such as fishing and the like is constructed of a light material such as styrofoam and has a horizontal main panel with an opening for a user to fit through so the floatation device surrounds the user. The device is designed to be easily accessible for the user, with a door provided on a side panel. The central opening in the main panel of the device accommodates the occupant to carry the device and wade into the water, and as the device begins to float, the occupant may sit on the main panel of the device.

A still for the distillation of water or other liquids, the still having a boiling chamber with a heater, a vapor condenser chamber, and a vapor separator chamber all supported by a frame having a catch basin below the chambers and a distilled liquid sump below the catch basin into which the condenser discharges. The chambers telescopically plug together in position on the frame and are easily separated and knocked-down for cleaning without requiring tools. The chambers are tubes having their ends removably plugged, and one of the plugs in the boiling chamber carries the heater with it, the heater coils supporting a convection sleeve which is easily separated therefrom for cleaning. The water level in the boiling chamber is controlled by connection with a separate tank having a float valve setting its own level, and the unit has automatic electrical shut-off switches operative when the sump is full or in case of overheating.

Still

A container for BB shot or other spherical pellets having a dispensing filler portion, useful for example for filling an air rifle, and having a container portion serving as a sales package and/or storage device, said dispensing filler portion comprising a tube of internal diameter slightly larger than the BB shot, and the filler portion being joined to a wall of the container portion by a transfer portion having a transfer slot which is about equal in width and in depth to the inner diameter of the filler tube and the slot length being at least equal to several BB diameters, the transfer slot serving to reduce bridging while the dispensing filler tube portion is being filled from the container portion, the tube portion being distorted to restrict it internally at a location near its discharge end which distortion can be manually straightened to dispense BBs therethrough, and the portions being made of transparent plastic so that the user can see when the tube portion is filled with BBs and can see his remaining supply.
