Title: Products based on plaster and processes for their manufacture
IPC: C04B24/30
Filed: 1978-07-26
Abstract: The process for the manufacture of a plaster product comprises adding a urea-formol or melamine-formol resin to a calcium sulphate base powder, the starting powder being constituted by partially hydrated calcium sulphate (plaster alone or with gypsum, or anhydrite with gypsum such as phosphogypsum). The percentage of resin, measured in weight of dry extract of the latter with respect to the weight of the dry extract of the powder to which it is added, is comprised between 1 and 5%. A powder-resin-water mixture is formed by a process of extrusion. The product thus formed is heated to a temperature comprised between 105 DEG and 120 DEG C. Articles having exceptional surface hardness and durability can be formed therefrom by a continuous extrusion.

Title: Improvement of signal/noise ratio in pyroelectric vidicon
IPC: H01J29/45
Filed: 1978-08-16
Abstract: A pyroelectric vidicon is provided with an improved signal-to-noise ratio by essentially eliminating pedestal noise and using a reflected or scattered beam electron multiplier 13, 14 to provide signal gain to overcome preamplifier noise. Pedestal noise is substantially eliminated by trimming the charge on the target 12, during the line flyback period, down to a small fixed potential, q above the quiescent value VQ set by secondary emission: a second line sweep during the flyback period or a sweep by a beam from an auxiliary cathode may be employed to trim the target potential. To improve scatter of the beam the target may be pyramidally reticulated.

Patent ES-477932-A1 (ES)
Title: An apparatus for generating heat from friction, together with a corresponding heater and method.
IPC: F24D/
Filed: 1979-02-21
Abstract: This invention proposes a heat generator by friction which consists of hollow inner and outer drums placed in a telescopically connected arrangement for relative rotation around a vertical shaft. These drums have facing circumferences with a small fixed intervening space between them so as to form a vertical annular liquid receptacle, and they also have bottom walls spaced apart to form a shallow liquid receptacle to receive oil. The oil normally only occupies this shallow liquid receptacle but, when the drums are rotated relative to one another, it goes up and into the annular liquid receptacle to transfer heat from friction to the drums. An electric motor is connected to one of these drums to make it turn on a vertical shaft in relation to the other drum at a substantial speed.

Title: Multi-motor suction cleaner construction
IPC: A47L9/28
Filed: 1979-09-12
Abstract: A multi-motor suction cleaner of the upright type having a power-driven rotary brush operated in the usual manner with a low-suction, high-volume airflow produced by a typical first motor-fan unit in the cleaner suction nozzle housing to carry out a usual floor, rug or carpet cleaning operation. The cleaner is converted to efficient off-the-floor cleaning merely by selectively uncovering an opening in a closed suction chamber carried by the cleaner containing a second motor-fan unit producing high-suction, low-volume airflow. A converter member mounted on one end of a typical flexible attachment hose is inserted in the uncovered opening. This automatically energizes the second motor-fan unit. The selective and alternate operation of the two motor-fan units provides a single cleaner that can carry out most efficiently every cleaning operation heretofore requiring both a canister and an upright cleaner to perform. In addition, the cleaner is convertible to blower operation by connecting the converter member to a blower receptacle also provided for the closed compartment.

Patent ES-8301321-A1 (ES)
Title: Hollow valve for an internal- combustion engine
IPC: F01P3/14
Filed: 1982-02-04
Abstract: The valve cavity is filled with coolant metal, such as sodium, which is liquid at the high operating temperature, and includes an additive tablet, constituted by zirconium, hafnium, yttrium, uranium 238 or mixtures thereof, having a greater affinity for oxygen, nitrogen, hydrogen and carbon in the valve cavity atmosphere than the coolant metal and the alloying elements in the valve walls.
