Title: Pastry baking oven - with ring carrying pendulum plates for pastry and horizontal charge and inclined discharge opening
Inventor: URBAN GOTTFRIED
IPC: A21B3/04
Filed: 1975-04-22
Abstract: A baking oven for pastry consists of horizontal cylinder in which a horizontal revolving ring carries a number of support plates which are suspended from it in pendulum fashion from pivots. A horizontal charging opening with door lies flush with the plane of the support plates when in the charging position. An inclined discharge opening is arranged below the charging opening, at an angle equal to the angle at centre of the pivots for the support plate suspension. This submits all pastry charges on the support plates to an absolutely uniform heat radiation which requires no massive heat storage plates to support the pastry. The charge takes place at the same height and not at various elevations like the multideck ovens. Charging and discharging is easily automated and the oven has a much higher throughput.

Title: Treatment of effluent streams containing organic wastes - Treatment of effluent streams contg. organic wastes
Inventor: HOLL PETER DR
IPC: B01J19/08
Filed: 1975-07-05
Abstract: Suspended and/or dissolved materials in effluent water streams are destroyed using accelerated electrons. The irradiation is carried out under mixing conditions with a particle energy of only 0.3-0.6MeV. Can be used for organic or inorganic cpds. e.g., phenols, benzene, toluene, xylene and derivatives, cyanates, alkalis from plastic prodn., residues from organic fertilisers, parathion, Mg and Cl cpds., froth producing organics, high mol. wt. proteins, ethanol, butanol, butyl acetate, formaldehyde, chloramine, carbohydrates, fats, urine, CHCl3, organic acids, organic dyestuffs etc. Radioactive materials can be used to produce gamma rays of energy 2-4 MeV. These penetrate well but require costly shielding around the equipment. Moreover, with radioactive materials the radiation cannot simply be switched off. It is thus unsuitable for effluent treatment. The system described allows the use of lower energy radiation.
