Title: Oven door locking mechanism - has push button actuated flexible member for releasing the locking catch
Inventor: FORSBLOM SYLVE BIRGER
IPC: F24C15/02
Filed: 1974-09-18
Abstract: Push button must be actuated in conjunction with the door handle for releasing, this ensures that the door lock and handle are safe against children. The oven door is provided with the handle which rotates the catch. The push button slides in the housing and it deforms the flexible strip to which it is fastened by a screw. The flexible strip is fastened at its upper end by its bent over part and the lower end of this flexible strip is rivetted. On pushing the button inwards the vertical part of the flexible element is curved and the lower bend of the flexible element is straightened and releases the door for opening. The lower part of the flexible member rises above the locking catch and hence the oven door can be unlocked and opened. When the push button is released then the flexible element assumes its original shape.

Title: Cigarette making machine porosity testing - suction signals compared with mean value signal
Inventor: REULAND JOACHIM
IPC: A24C5/34
Filed: 1974-09-19
Abstract: A cigarette making machine includes a system of testing the filter tipped cigarettes for leakages in the wrapping paper around the tip, where the cigarettes are conveyed by a suction drum past a tube through which a vacuum is applied to one end of the cigarette, and the suction is measured at the other end by two equaliser devices, and evaluation and comparison systems in which values below a given level operate a rejection system which blows the faulty cigarette from the test drum. The measured suction signals are converted to electrical signals, fed to an equaliser, and compared with a mean value forming device connected to a sample and hold amplifier which in turn control the ejection system.

Title: Anti skid braking system for tracked vehicles - switches from electro dynamic to friction braking on appearance of axle wheel locking
Inventor: FALKE ERICH
IPC: B60T8/32
Filed: 1974-09-19
Abstract: Normal braking is accomplished by an electro dynamic brake to reduce the trains speed from a first velocity to a reduced velocity at which point the electro dynamic brake is automatically switched off and the train halted by a friction brake. Should one or more axle wheels lock during the electrodynamic braking process the friction brake anti skid regulator of the axle wheel or wheels concerned automatically switches off the electro dynamic brake, and changes over to friction braking. The trains retard rate remains unaltered and braking power is disconnected from the axle wheel or wheels which are locked. A time unit is provided to restore electro dynamic braking after a predetermined time lapse.

Title: Oil separator for vehicle drive mechanisms - has filter or centrifuge before or after it
Inventor: BREUSTEDT KONRAD
IPC: F01M11/04
Filed: 1975-02-06
Abstract: An oil separator as in 2359244 removes used and vitiated oil from the engine gears, transmission and drive shafts of any type of vehicle.

Title: Filter for removing fine dust from gases - with periodic back-blowing, has uniformly distributed bottom gas entry to ensure uniform settling of dust
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/00
Filed: 1975-11-11
Abstract: A bag filter for removing dust from flue gases or other gases has periodic, successive back-flow purging, causing the dust to fall into a collecting chamber. It is raised again by the inflowing gas and returned to the region of the filters. This process is repeated until the gas is dust-satd., then the dust extractor at the bottom of the collecting chamber is operated. More uniform upward flow of gas, and therefore downward flow of dust is obtd. by the continuous bottom inlet distributor.

Title: Energy production from power station waste steam - using turbine in waste steam line to vacuum space in toricelli type condensation tube
Inventor: GULAIF JOSEF
IPC: F01K9/00
Filed: 1976-08-23
Abstract: The arrangement produces mechanical or electrical energy from low-pressure low-temp. waste steam from a power station by the use of the vacuum maintained above the level of the water in a tube by that water. The steam is allowed to expand into the vacuum space where it condenses, and the expansion is used to drive a turbine arranged in the tube through which the steam flows to the vacuum space. The turbine drives a generator arranged outside that tube. A valve between the expansion turbine and the vacuum space permits the rate of expansion to be controlled.

Title: Stress relieved circular saw blade - has kidney shaped holes to reduce thermal stresses and provide effective cooling
Inventor: FELDE JOERG DIPL ING
IPC: B23D65/00
Filed: 1977-01-31
Abstract: The circular saw blade has eight kidney shaped holes. The positions of the holes are defined by two ellipses with their major axes perpendicular to each other. A hole is made at each end of each main axis and also at the points of intersection of the circumferences. This pattern of kidney shaped holes reduces the thermal stresses and centrifugal stresses induced during the operation of the saw. In addition the slots assist the flow of cooling air over the blade and so reduce the working temp. Other patterns of slots and holes can produce the same effect.
