Patent ES-448446-A1 (ES)
Title: Method for heat supply to the solvent bath of a degreasing apparatus
IPC: B01D5/00
Filed: 1976-06-01
Abstract: In the degreasing device, the liquid solvent (3') is evaporated in a liquid compartment (1') and the solvent vapour (6') is condensed on a cooling coil (7'). To save energy, the heat carried off to the cooling coil (7') is again supplied to the liquid compartment (1') via a heat pump system. To this end, in the exemplary embodiment illustrated, a part of the solvent condensed on the cooling coil (7') is expanded via an expansion valve (14), evaporated in the cooling coil (7'), compressed in a compressor (10) and subsequently condensed in the liquid compartment (1'), yielding heat.
Patent ES-451915-A1 (ES)
Title: Electric power plant and turbine acceleration control system for use therein
IPC: F01K13/02
Filed: 1976-06-28
Abstract: An electric power plant having dual turbine-generators and a steam source which includes a high temperature gas-cooled nuclear reactor. Each turbine includes a high pressure portion driven by superheat steam and a lower pressure portion driven by reheat steam. A turbine bypass system permits minimum flows of superheat and reheat steam from the source at times when the turbines require flows of such steam that are less than the minimum flows. Before it is reheated, steam that has passed through the high pressure portions and their bypass lines drives auxiliary steam turbines that rotate means for propelling the coolant gas through the reactor. During acceleration of a turbine-generator to its synchronous speed, one of the steam flows through its high and lower pressure portions is varied to govern the shaft speed, while the other flow is held relatively constant, that one of the flows which is varied being determined by the shaft speed. As the turbine-generator is accelerated, the steam flow through a bypass line associated with its lower pressure portion is varied to compensate changes of flow through that portion, in order to maintain a desired pressure of hot reheat steam.

Title: Method and apparatus for pouring a mold with a selectable amount of casting material
IPC: B22D39/00
Filed: 1977-03-11
Abstract: The amount of liquid metal casting material poured into a mold from a receptacle located above the mold from pouring means in the bottom of the receptacle is controlled by continuously sensing the pressure head of the liquid metal casting material in the receptacle during pouring of the mold, numerically integrating to a constant value the product of the multiplication of a function of the pressure head and time, and controlling the pouring means to terminate the pouring of the mold when a predetermined set value is attained. Electronic control circuitry receives as an input signal a signal representing the pressure head of the liquid casting material within the receptacle and a control function is effected by the electronic control means to stop pouring when a selected predetermined amount of material has been introduced into a mold. The quantity of casting material poured into a filled mold is sensed and a feedback signal is provided to adjust the control function when the amount of casting material in the filled mold is found to deviate from a desired amount. Furthermore the electronic control circuitry may be equipped with a mechanism to sense variations in the rate of flow of the pouring device and to adjust for changes.

Title: Process for the separation of polyvinyl alcohol from aqueous solutions
IPC: C02F9/00
Filed: 1977-12-30
Abstract: In order to protect the environment from pollution, it is desirable to keep the polyvinyl alcohol content in waste waters as low as possible. Polyvinyl alcohol may be removed from waste waters by means of microorganisms on the the one hand, and on the other according to chemical/mechanical methods by salting-out and precipitation and subsequent separation of the solids. Advantageous is the precipitation in the form of a polyvinyl alcohol/boric acid/didiol complex, especially by means of alkaline earth metal hydroxides in an alkaline medium. Calcium hydroxide is a particularly suitable alkaline earth metal hydroxide.

Title: Skinning machine for bacon or the like
IPC: A22C17/12
Filed: 1978-04-05
Abstract: A skinning machine for bacon has a transporting conveyor which advances successive slabs into a passage between the discharge end of the conveyor and a pivotably mounted hold-down roller.

Title: DC motor drive for diesel electric ship - has transformer between AC supply and rectifier whose windings can be switched at low speeds for high efficiency (NL 2.3.79)
IPC: H02P7/293
Filed: 1978-08-30
Abstract: The DC motor driven ship has the motor speed controlled by a rectifier with thyristors and commutating chokes. Diesel or gas turbine engines drive alternators. In order to achieve an optimum efficiency at low motor speed a transformer is connected between the controlled rectifier and the a.c. supply. The primary and or secondary of the transformer is switched or shorted for the lower speeds. The system uses the full capacity of the rectifiers even at low motor speeds so that cable runs can be kept to an optimum thickness and an efficient performance assured. The transformer switching reduces the voltage applied to the rectifiers and increases the commutation reactance.
