Title: Fungicide mixtures of tin cpds and cyclic bis - dithiocarbamates
IPC: C07F7/00
Filed: 1969-10-10
Abstract: Fungicide mixtures of tin cpds. and cyclic bis dithiocarbamates. Mixtures of a Sn compound of formula (C6H5)3SnLX n- A n+ (I) (in which X = Cl, Br or CNS, A = substituted ammonium-, phosphonium- or sulphonium- cation, n is either 0 or 1, and L = Cl, Br or CNS where n = 1, and a ligand with an electron donating gp. of the type triple bond N right arrow O, triple bond P right arrow O or =S = O where n = 0) and an alkylene, bisdithiocarbamate of formula: (in which R = H-, or CH3- and Me = Zn, Mn or Fe or mixtures thereof) are useful fungicides. The ratio of compounds (I to II) may vary between 5:1 to 1:1 and the phytotoxicity of (I) is greatly diminished by the presence of (II), due to synergism. In an example, in which tomato plants were treated with an aqueous suspension of 1015 ppm Decafentin (Triphenyl-decyl-phosphonium- triphenyl-brom-chlorostannate ), the incorporation of 20% Maneb (II, Me = Mn) in the Decafentin, reduced the attack three-fold, as measured on the biological scale of the Bundesanstalt.

Title: Rotary kiln driers with improved heat transfer through - the dried materials
IPC: F26B11/04
Filed: 1969-10-16
Abstract: Rotary kiln driers with improved heat transfer through the dried materials. G2-. Are provided internally with radially extending vanes whose tips terminate either in the centre or are provided with hooked portions, the former vanes or the hooked portions being provided with apertures so that the tumbled drying material by fallying through the apertures to the subjacent vanes is exposed for a longer period to the action of the drying gases. Arrangement of vanes increases the rate of heat transfer through the material to be dried and therefore the rate of drying in the rotary kiln.

Title: Two-stage filtration process
IPC: B01D29/05
Filed: 1970-12-02
Abstract: Separator for separating particles of foreign substances from a liquid has a container with a liquid entrance, a sedimentation space in which the particles are separated from the liquid by gravity, an outlet for purified liquid, and a filter for the liquid placed between the sedimentation space and the outlet, this filter separating the particles from the liquid, a pump for pumping the liquid from the entrance to the outlet, and hydraulic means for directing an impulse or shock wave towards the filter in order to detach the adherent particles so that they fall into the sedimentation space.

Title: Electronic tube emitter fabrication process - produces tungsten coated emitter with large working area for use in electronic converters
IPC: G21H1/10
Filed: 1973-08-14
Abstract: The electron tube emitter electrode is made of a tungsten (W) covered substrate (S) such as molybdenum.

Abstract: In a machine for moulding measured volumes of a fluid paste, e.g. a food product e.g. as cheese. The machine combines storage space and controlled heat treatment for the paste, means for cutting and drainage of the paste, i.e. partic. curds for cheese making, a volumetric paste depositor and mould blocks on a conveyor which positions empty moulds for filling from the depositor and moves filled moulds on to be replaced by empty ones; all operations are effected mechanically and automatically in conjunction with gravity flow of paste right through from storage space to mould cavities, the rate at which paste is delivered into both depositor and mould cavities being continually controlled. The depositor pref. comprises a rotary, cylindrical drum, which has volumetric cavities filled from the storage space, the drum then rotating through 180 degrees to deliver paste from depositor cavities into mould cavities. Depositor and mould cavities are pref. lined with elastic sleeves which practically fill the cavities when inflated with compressed air and are controllably deflated to regulate flow of paste into the cavities. The texture and quality of the prod. is protected against undue transfer speeds into mould and depositor cavities.

Title: Modular bakery cooking oven - which can be adapted for different needs and is heated by hot oil circulation
IPC: A21B7/00
Filed: 1976-09-30
Abstract: Cooking oven,partic. for bread dough and pastries, has a central heating unit and pump which circulates a heat-carrying oil around a number of independent, modular cooking chambers. Each chamber is divided by a number of horizontal shelves made from heat exchange tubes; they are arranged parallel to each other and are joined to collecting tubes, one of which is closed at one end while the other end is connected the distributing column for the hot oil. These columsn extend beyond the insulated top and are coupled by means of dis-mountable flanges to the main oil pipe system. Cooking is effected by the transfer of calories from the hot oil in the heat exchange tubes of the shelves and the fibrous cement base. The dough to be cooked is placed directly on this base or on a grid for charging and discharging. One heating unit can thus be associated witn >1chamber. The capacity of the oven can be adapted to different needs by the addition or omission of chamber modules from th hot liq. circuit. With the compact modules, charging and discharging of the different shelves can be effected and simultaneously by means of a mobile palette transporter.
