Title: High output infra-red oven - one or more conveyor belts to ensure continuous operation
IPC: F24C7/02
Filed: 1974-07-25
Abstract: An infra red cooker or heater for food, to be used in large restaurants, canteens etc., uses on or more conveyor belts which may be integral with the oven or separate, so that a constant continuous flow of food can be maintained for increased output. The speed of the belts can be varied by a suitable control mechanism incorporated with the drive, and the size of the oven can be made to conform with the belt speed and length. The belts do not affect the operation of the oven. Loading and unloading can take place outside the oven, and screens can be fitted at the feed and discharge ends to form the oven chamber between. Unlike conventional ovens, there is not time lost for stopping, starting, loading and unloading.

Title: Low noise cooling system for motor vehicles - has blower with tangential flow and high efficiency for reducing turbulence
Inventor: HAUSER KURT
IPC: F04D29/16
Filed: 1976-07-12
Abstract: Downstreamm of the heat exchanger (1) is arranged a radial blower rotor (12). The ratio between the smallest cross section of the inlet nozzle (2) upstream of the rotor (12) and the cross section of the blade inlet cross section of the rotor is specified to ensure high efficiency. The inlet nozzle which projects into one rotor cover plate expands after the narrowest cross section in the downstream direction. This expanding section imparts an outwards directed component to the flows. These flows are thus directed tangentially to the curved part of the rotor cover plate (3).
