Title: Building construction
IPC: B28B7/22
Filed: 1971-11-11
Abstract: Box-like units having at least one open side for use, for example, in the construction of prefabricated buildings are cast from a composition of gypsum and water optionally including other material such as Portland or Aluminous cement. The mixture is cast between an external mould defining the external faces of the unit and an internal core defining the internal faces of the unit and the core is formed from, or covered with, material which causes its faces which come into contact with the mixture to have a higher co-efficient of heat reflection than that of the faces of the external mould which come into contact with the mixture. The mixture is allowed to set and the external mould is removed, after which the mixture is allowed to harden further and during this hardening becomes heated by the exothermic reaction between the gypsum and the water to cause the hardened mixture to expand away from the core. This allows the core to be subsequently removed without it being necessary to make the core collapsible.

Patent ES-412306-A1 (ES)
Title: Threshold detector for a voice frequency receiver
IPC: H04Q1/453
Filed: 1973-03-03
Abstract: A threshold detector is disclosed which provides an output signal in response to a sinusoidal signal from a band pass filter while the sinusoidal signal has a voltage level equal to or above a reference voltage. The detector employs an operational amplifier as a first comparator or detector circuit to provide a pulse in response to each excursion of the sinusoidal signal above the threshold value. Current from the pulse is used to charge a capacitor in an RC circuit to a level above the reference voltage. A second operational amplifier is connected to the RC circuit to provide the desired constant output voltage so long as the stored voltage is equal to or above the reference voltage. Feedback from the output of the second operational amplifier to the input of the first operational amplifier is used to adjust the reference voltage to a level which makes the threshold detector insensitive to noise input associated with the sinusoidal signal.

Title: Device for separating impurities from gases by means of a washing liquid
IPC: B01D3/26
Filed: 1975-07-17
Abstract: A device for separating impurities from gases by means of a washing liquid. The device includes three (3) interconnected chambers: a suction chamber, a mixing chamber and a separating chamber, wherein the outer wall of the mixing chamber is the inner wall of the suction chamber and the inner wall of the mixing chamber is the outer wall of the separating chamber. In the upper portion of the mixing chamber there is an inlet which connects the suction and mixing chambers for conveying contaminated gases rising in the suction chamber downwardly into the mixing chamber. In the upper portion of the mixing chamber below the outlet there is mounted a plurality of spray nozzles for downwardly spraying washing liquids which removes impurities in the contaminated gases as they flow downwardly through the mixing chamber. At the bottom of and directly open to the mixing and separating chambers is a liquid collection chamber for collecting used washing liquids and impurities from the gases. In the inner wall of the mixing chamber above the collection chamber is an outlet which conveys the washed gases from the mixing chamber upwardly into the separating chamber. The separator in the separating chamber removes remaining droplets of liquid from the washed gases before the washed gases pass into the surrounding atmosphere. Within an outer wall of the suction chamber there is an exhaust opening which is normally closed. When the device is operating properly the opening remains closed so that the contaminated gases will pass from the suction chamber to the mixing chamber. When there is a breakdown, however, the opening is opened so that the contaminating gases are exhausted from the device without passing therethrough.
