Patent DE-2853055-A1 (DE)
Title: Safety arrangement for domestic and industrial refuse incinerators - has alternately operating chute inlet with outlet flaps and damping stem injection (NL 10.6.80)
IPC: F23G5/50
Filed: 1978-12-08
Abstract: The incineration takes places on normal grates, or air furnaces with rotary drum grates. The chute down from the funnel has motorised top and bottom flaps, interlocked to operate alternately. The space in between is rendered inert by the injection of steam at 1.2 - 2.5 bar and 110 - 150 deg.C through one continuously open line and another intermittently opened by a motorised valve powered from the lower flap operating circuit. A timing unit operates this valve and, via a delay unit, also the lower flap on completion of the additional steam injection. The process ensures stable temperature at the chute of 40-60 deg.C, which reduces its soiling and clogging. It also provides safeguards against plane flash-back and reduces the steam consumption.
Patent DE-2901270-A1 (DE)
Title: Circulating liq. heat output measuring device - integrates product of flow rate and temp. difference across heat exchanger, e.g. for central heating radiators
Inventor: DANIEL WALTER ING GRAD
IPC: G01K17/08
Filed: 1979-01-13
Abstract: The heat output measuring device determines the heat supplied to a heat exchanger (14) by a pumped, circulating liquid heating medium. The flow resistance through the heat exchanger can be varied by a valve (36), and two temp. monitors (38, 40) determine the temp. of the liquid before and after the heat exchanger. The product of the flow rate and the temp. difference is integrated. Two flow resistances (30, 32) are connected in the bypassline (22) for the heat exchanger between the two temp. monitoring points, controlled to obtain a given constant flow rate through the bypass line for all positions of the valve associated with the heat exchanger, so that an integrator (42) need only be connected to the two temp. monitors. Pref. the heat exchanger and the associated valve are connected across one flow resistance (30), with the other flow resistance (32) in series with it.

Title: Gas:dynamical mixing of molten metal - by cyclic extn. of metal portion and reinjection at deeper level
Inventor: DOLSCHENKOV BORIS SERGEEVITSCH
IPC: F27D27/00
Filed: 1979-01-29
Abstract: Molten metals in the hearth of a melting furnace are mixed on gas dynamical principles by extracting a portion of the molten metal near the surface by a gas dynamical pump and by re-injecting it by compressed gas at a deeper level, pref. combined with a swivelling of the lance through a certain angle. This greatly improves the mixing efficiency and reduces the duration of a melting cycle by 20-25%.

Title: Horizontal interlocking curved aluminium roller shutter slats - are rigid hollow boxes with helical side chamber walls
Inventor: RIEDEL OTTO
IPC: E06B9/15
Filed: 1979-07-19
Abstract: Hooks, or similar, connect slightly arched profiles of extruded light metal, permitting limited mutual swivelling, where these are aligned horizontally in a roller shutter; on one side they have a open-fronted front-chamber, and on the other a rear-open rear chamber, limitedby rounded walling enclosing an acute angle. The profiles (1) are in hollow box shape, flexurally and torsionally rigid. The chamber walls (8,9) are spiral, with curvature radius gradually diminishing so that each has its outer end running into the hook (6,7) which is turned back towards the profile. The hooks outer wall extends parallel to the chamber wall from the profile outside facing the support edge (10,11). This has enhanced stability,but permits a wide roller shutter to be compactly rolled up.

Title: Power tube cathode grid - containing shadow grid material in holes produced by laser beam
Inventor: SCHMITT HARTMUT ING GRAD
IPC: H01J9/04
Filed: 1979-07-28
Abstract: The parent Patent No. 2535467 described a method of producing a cathode grid assembly for grid controlled power tubes with a shadow grid formed by filling out recesses in the emission layer. Instead of producing these holes by spark erosion, it is now suggested to use a laser, preferably a neodymium YAG laser for this purpose. The beam of a neodymium YAG laser is used to remove the emission material from the layer (2) in a certain pattern. The produced holes are filled with a shadow gat material (3) such as molybdenum or tungsten, and coated with a material (4) to suppress the electron emission, e.g. zirconium or carbon. It was found that the dielectric liquid needed for spark erosion contaminates the cathode emission material. Spark erosion also opens the pores of thin material to an undesirable degree. The new method prevents all this.

Title: Rotating radio direction finder - has circular AM or FM antenna characteristic plus reference antenna with carrier sensing for summator blocking
Inventor: PICHL HANS
IPC: G01S3/58
Filed: 1980-05-21
Abstract: The direction finding antenna is coupled to a scanning device producing a rotating antenna characteristic which is analysed w.r.t. a reference signal from a reference antenna in a receiver with a compensation mixer with intermediate frequency synchronisation. The intermediate frequency direction signal is fed to the reading-in section of a summator where it is placed in a store, read out continually, demodulated in an F.M. demodulator and finally analysed in the actual phase measurer (11). The reading-in unit is controlled by a timing frequency, as is the reading-out unit, both frequencies corresp. to the rotation frequency of the antenna. The receiver has an additional carrier sensor connected to it, which very quickly establishes whether a signal is received or not. This sensor controls the reading-in unit of the summator, via an additional control unit in such a way, that a signal is only read into the summator when the direction signal is present. If the carrier sensor indicates no signal, the reading-in procedure is blocked.

Title: Mould for foam prods. with subsequent compaction - provided by relative movement of half moulds during or after foaming
Inventor: HAHN ORWIN PROF DR
IPC: B29C44/58
Filed: 1980-05-31
Abstract: Method of producing a moulding, esp. from a foamable thermoplastics, uses a closed mould and includes the subsequent compaction of the moulding, opt. accompanied by heat treatment. This after-compaction is carried out in the mould cavity during or after the steaming or sintering of the moulding, by bringing the half-moulds themselves together. Pref., the half-moulds fit one into the other in the manner of a piston and cylinder; in a first stage, with excess vol. of the cavity, the material is introduced and foamed, while in a second stage the half-moulds are brought closer together to define the final vol. Used pref. for the prodn. of mouldings from foamable thermoplastic materials, esp. those which have a complicated form involving thin sections and require a hard surface. The method enables this to be achieved without the use of separate movable parts of the half-mould.

In another system a third contact is held in the patient's head and is held against a conductive plate mounted on the wall when the patient is at the highest point.
