Patent DE-2923285-A1 (DE)
IPC: G05D21/02
Filed: 1979-06-08
Abstract: The control of the composition of the atmosphere of an oven for the nitridation of the surface of ferrous workpieces or similar by means of a gas containing hydrogen or ammoniac, comprises an ammonia cracking plant which introduces at least one part of the gas containing ammonia in the chamber (1) of the oven. An adjusting member (13, 14) controls the flow of the cracked ammonia towards the oven as a function of measured values which are provided by a sensor (12) from the gases samples continuously from the oven and by means of an appropriate electric circuit. To comply with the different operation conditions in a simple way and to take into account automatically all the essential parameters of the process for appropriately effecting the nitridation, the adjusting member (13, 14) controlling the supply of cracked ammonia cooperates, upstream, with a programmer (16) which provides to the adjusting member (13, 14) an order value depending on the programme. Thus, the programmer (16) controls in addition the adjusting member for the supply of cracked ammonia to the oven (1) and a temperature regulator (17) of the oven (1) by means of a programme order value.

Title: New born baby resuscitation ventilator - has second stage with adjustable throttle in vent from water trap
Inventor: BEYREUTHER CHRISTIAN DIPL PHYS
IPC: A61M16/00
Filed: 1979-07-24
Abstract: The ventilator is used for resuscitation of new-born babies. It has a water trap acting as inhalation valve and a T-piece branch from the trap standpipe, by which the trap is connected by hoses to the respiratory gas supply and to a patient's adapter. The latter has an exhalation port to atmosphere which can be shut off. The quantity of gas from the supply is adjustable, and the maximum immersion depth of the standpipe determines the maximum inhalation pressure. The period for which the exhalation port is shut determines respiratory frequency and timing. A second respiration stage, comprising the water trap (2) and a throttle (6) in the vent from the latter, can be cut in. Both throttle cross-section and quantity of respiratory gas supplied determine the inhalation pressure.

Title: Sheet metal part storage equipment - has supporting arms swung by gravity from working to receiving position
Inventor: UDELHOVEN DIETER ING GRAD
IPC: B65G1/14
Filed: 1979-07-25
Abstract: The equipment stores parts of roughly the same shape and size at intervals one above the other, being for sheet-metal and parts formed from it in particular. It comprises a frame with double-armed levers tilting on horizontal pins, one arm being the supporting one and the other the control one. When a part is placed on an arm in the receiving position it tilts into the working position and simultaneously tilts the one above from the rest to the receiving position. The torque resulting from gravity exerted by the control arm (6) exceeds that exerted in the opposite direction by the supporting arm (5) by an amount such that when the part is lifted off the latter is swings from the working to the receiving position, and when the next part is removed it moves into the rest position.

Title: Vehicle tyre with radial carcass and auxiliary bead - permits reduced side wall thickness whilst increasing rigidity
Inventor: WALL KLAUS V D
IPC: B60C15/05
Filed: 1979-09-08
Abstract: The tensile load bearing details of the carcase of a radial tyre are folded around the bead core, and butt against those facing the inner cavity of the tyre. The ends of these load bearing details are further enclosed by an auxiliary highly tensile core which is at the height of the bead of the wheel rim. Above the auxiliary core one or more strips of woven fabric with legs, roughly of the same length, are arranged between the wheel bead and the carcase, and run at an angle to the load bearers of the carcase. They are anchored by folding over the auxiliary core and extend above the wheel bead, but end at about one third or one fifth of the height of the side wall. The auxiliary core makes possible a reduction in the thickness of the side wall whilst rigidity increasing towards the core is obtd.

Title: Electrical washing machine drive - with pole changing drum motor and separately driven fan motor supplying input voltage for speed control
Inventor: HANNING MICHAEL DIPL ING
IPC: H02K9/00
Filed: 1979-09-17
Abstract: A washing machine drive furnishes in addition to the washing, compacting and spin drying speeds, two gentle speeds for wahsin washing and spin drying delicate fabrics by a pole-changing " asynchronous motor and a cooling fan for it with a separate drive. The asynchronous motor is fitted with an electronic speed control. The fan motor is equipped with a transformer winding which supplies the input voltages for this speed control and for a pulse generator on the asynchronous motor which determines the actual value of its speed. The asynchronous motor is thereby always cut in when the voltage passes through zero, and cut out when the current passes through zero. The result is a constant speed at all desired levels.

Patent DE-3018450-A1 (DE)
Inventor: DIBELIUS GUENTHER PROF DR ING
IPC: C10J3/54
Filed: 1980-05-14
Abstract: In a method for the generation of heat using a heat pump in which a heat carrier fluid is heated by a heat exchanger and compressed with temperature increase in a subsequent compressor, heat is delivered therefrom to a heat-admitting process; the fluid is then expanded in a gas turbine, producing work, and afterwards its residual heat is delivered to a thermal power process, the maximum temperature of the energy sources of which, that provide work for the compressor, lies below the temperature of heat delivery. The main heat source can consist of an exothermic chemical or nuclear reaction and the heat-admitting process can be a coal gasification process. The work in the compressor is furnished essentially by the gas turbine and the thermal power process.

Title: Vegetation supporting pitched roof layer drainage - is sited between shear absorbing units containing water supply and run off holes
Inventor: DREFAHL JENS ING GRAD
IPC: E04D11/00
Filed: 1980-05-23
Abstract: The pitched roof has vegetation planted on it. There is a support structure and waterproof roof skin, and drainage provision is sited on the skin, in conjunction with a rot-proof lattice-type grid configuration as in 3015147. The drainage system (200) is formed by the applied layer, or made as a separate drainage layer, and located in the accommodation areas of the grid configuration (10) between the members (212,214,216) absorbing and deflecting shearing forces. These members, interrupting the drainage system, have apertures for water drainage and/or for watering. This effectively eliminates shearing forces from the drainage system, independently of roof skin, and is simple and inexpensive.
