Title: Refrigerating equipment for cooling a fluid
IPC: F25B41/06
Filed: 1970-03-04
Abstract: The invention relates to refrigerating apparatus for cooling a fluid which may be either a liquid or a gas. The components include, in addition to the conventional compressor, condenser and evaporator, a pilot evaporator unit on the downstream side of the evaporator.

Title: Method and apparatus for straightening continuous casting
IPC: B21B13/22
Filed: 1972-08-16
Abstract: A method and apparatus for straightening castings formed in a continuous-casting operation. After a partially solidified casting emerges from a continuous-casting mold, it travels through bending rolls and a curved roll rack which change its direction of travel from vertical to horizontal, but the casting acquires a curved set and must thereafter be straightened. The straightening apparatus of the present invention includes lower and upper series of rolls closely confining a casting, yet avoiding excessive forces such as would damage the casting, which may still have a liquid core. The apparatus has a critical combination of driven and idler rolls of varying diameters, which afford the necessary mechanical strength at reaction points, yet maintain minimum spacing between rolls in each series and allow standardization of the drives for the driven rolls.

Patent ES-448337-A1 (ES)
Title: Auxiliary power steering systems for heavy duty vehicles
IPC: B62D12/00
Filed: 1976-05-28
Abstract: Dual double acting servomotors hydraulically pressurized are provided wherein the pistons have shunt valve means actuatable at limit of movement of the pistons to shunt high pressure fluid at one side of the piston to the low pressure side of the piston then being exhausted. This results in relieving the stress otherwise effected against steering mechanism limit stops by continued application of high pressure feed to the pressurized chamber. The system encompasses steering control and shunt circuit valve means automatically actuated by differential pressures so as to direct pressure and exhaust flow selectively to and from the chambers of the respective cylinders from an engine driven pump and a manual metering pump for operating the steered wheels of heavy duty vehicles and which valve means effects bypassing of the engine driven pump pressure feed directly to one servomotor while feeding the combined pressures of that pump and the metering pump to the other. Both servomotors act to effect steering with no loss of synchronization.
Patent ES-451999-A1 (ES)
Title: Compound D.C. electrical motor with shunt field demagnetization protection
IPC: H02P1/18
Filed: 1976-09-30
Abstract: A DC electrical motor of the form having one field winding connected in series with the armature winding in addition to a shunt field winding connected in parallel with the armature winding is provided with a diode or the like in the shunt field winding circuit. This blocks reversed current flow in the shunt field winding which can otherwise occur during start-up due to an inductive interaction with the series field winding and armature circuit. The diode or the like enables faster magnetization of the stator poles by preventing creation of negative shunt field ampere turns due to the magnetic couple with the series field-armature circuit during the motor start period. Faster starting of the motor results, and adverse effects such as heating, brush deterioration, and commutation problems are reduced.
Patent ES-452073-A1 (ES)

The signals appearing across the two outputs of the filter have different phases if an input signal has a frequency equal to the tone signal frequency. The value of the phase difference is converted to a DC-component by the limiting means and the modulator, and the magnitude of the DC-component forms an indication of the desired tone signal.

Title: Pneumatically controlled tamper
IPC: E02D3/068
Filed: 1977-04-16
Abstract: A pneumatically controlled tamper includes a cylinder which has a lateral supply opening for compressed air and which is integral with a foot.
