Patent ES-397646-A1 (ES)
Title: Vapor generators
IPC: F22B1/26
Filed: 1971-12-03
Abstract: Apparatus for the generation of liquid vapor under pressure by means of heat from the combustion products of an internal combustion engine comprises a reservoir for the liquid to be vaporized having an inlet duct for the combustion products which communicates with the lower part of the interior of the reservoir. The combustion products pass from the inlet duct into the reservoir by way of a screen formed with a large number of small holes providing free passage for gas or liquid and this screen is preferably formed by an extension of the duct lying within the reservoir and formed with the small holes round its periphery. As a result of this construction the combustion product may bubble upwardly through liquid in the reservoir so as to transfer heat directly to the liquid with a high rate of heat transfer. An outlet from the reservoir is preferably so constructed as to reduce the amount of liquid carried over with the vapor and the outlet line may pass through at least one further closed vessel in order to trap any residual liquid. The internal combustion engine supplying the combustion products is preferably of the free-piston type and includes an arrangement for avoiding excessive heating of a release valve and its seat. For this purpose a duct is provided to supply liquid to a chamber in contact with the heated portion of the cylinder head and this chamber includes a portion adjacent the seat of the release valve which includes narrow outlets opening into the inlet duct in the region of reduced pressure immediately following the valve opening. In this way liquid is drawn into the inlet duct leading to appreciable cooling of the release valve and its seat.
Patent ES-401545-A1 (ES)
Title: Steering mechanism
IPC: B62D3/08
Filed: 1972-04-07
Abstract: A mechanism for actuating vehicle steering rods is provided having gearing intermediate the steering spindle and a nut operated rod actuator in order to increase mechanical advantage, particularly for heavy vehicles. Thus, in the event of pressure power failure used in booster steering, manual operation is readily usable without the usual extremely heavy physical force necessary with conventional mechanisms. Further, the invention used with or without power steering overcomes a drawback of prior art so-called rack steering arrangements. Thus, the gearing required for actuating steering rod mechanisms becomes increasingly larger where used for larger vehicles due to the increased steering forces required. This results in a loss of mechanical advantage at the steering wheel with conventional mechanisms, a condition precluded by the present invention which substitutes a rod actuator driven via bevel gears having a ratio affording a mechanical advantage.

Patent ES-441084-A1 (ES)
Title: Gating circuit
IPC: F16P3/20
Filed: 1975-09-17
Abstract: A current sensor provides a positive voltage when a non-desired condition is present, such as rotation of machinery above a predetermined speed, and a gating circuit causes contacts of a relay to close whenever the rotational speed drops below such predetermined speed, that is when the desired condition is achieved. The gating circuit also closes these relay contacts in response to failure of the electrical power to such gating circuit. The circuit includes a P-N-P transistor in series with the relay coil, which transistor is switched on or off by a NAND gate. A low level signal to the base of the P-N-P transistor is provided through the NAND gate when the inputs to the gate are high, thereby providing a fail-safe feature for the relay because one of the NAND gate inputs is provided from the sensor's reference voltage through a Schmitt-trigger circuit. Another NAND gate input is provided in pulse form through an amplification stage, and through another Schmitt-trigger circuit, to a retriggerable monostable integrated circuit chip. This input is also fail-safe in that any electrical interference on the input side of the MOS chip and Schmitt-trigger circuits will cause a low level output from the NAND gate, switching the relay contacts open, or off.

Title: Sling device for suspending animals or articles
IPC: A01K45/00
Filed: 1976-04-15
Abstract: A sling device is disclosed for suspending animals, particularly fowl, or articles which have an elongate portion which can be used as the legs of fowl. The sling device comprises a generally C-shaped bracket member with a pivoted lever at one end biased, e.g., by a counterweight, to a rest position. A cord or strap is connected between the other end of the bracket member and a point spaced from the end of the pivoted lever remote from the pivotal mounting of the pivoted lever. In the rest position, the cord is pulled taut under the action of the counterweight. The animal or article is urged against the taut cord, forming a loop therein and moving the points of attachment of the cord relatively towards each other. When the animal or article is released, the weight of the same causes the loop to tighten about the animal or article, ensuring suspension. Alternatively, the end of the cord attached to the bracket member may be attached to another lever pivoted towards the first pivoted lever in the loop forming position. Instead of the counterweight a spring may be used to bias the device to its rest position. The first pivoted lever may be replaced by a movable arm slidable along one leg of the bracket member under the action of a spring.
