Patent ES-458160-A1 (ES)
Title: Buoyancy control apparatus for divers
IPC: B63C11/08
Filed: 1977-04-14
Abstract: A buoyancy control system for carrying by a diver has a fluid-tight reservoir comprised of a plurality of parallel longitudinally extending passageways, into which water and compressed gas can be selectively admitted through respective inlet valves to displace gas and water respectively in the reservoir through respective outlet valves. The relative amounts of water and gas in the reservoir can therefore be adjusted to provide a required degree of buoyancy for the diver.

Title: Method of producing a tire for a pneumatic tire arrangement
IPC: B29D30/30
Filed: 1977-11-22
Abstract: Carcass plies for radial-ply tires are prepared by coating individual reinforcing strands with a rubber composition, and winding the coated strands in a winding machine with relatively weak transverse circumferential strands into a continuous cylindrical tube in which the reinforcing strands are substantially parallel to the tube axis and circumferentially spaced, and are connected by the circumferential strands of weaker material. Axial sections are cut from the tube, and only the axially central, annular portion of each section is expanded radially during shaping of the carcass, thereby stretching or breaking the transverse, circumferential strands.

Abstract: A transfer conveyor, for the transfer of piece goods from a first roller track conveyor to a second roller track conveyor, is disclosed which comprises a fixed base and a first frame carrying rollers rotatably mounted on the first frame and engaging inclined ramps fixed on the base. The first frame carries two endless conveying chains extending in parallel vertical planes spaced apart in the conveying direction of the roller track conveyors, said chains having horizontal upper runs which in a lowered position of the first frame lie below the conveying plane of the roller track conveyors and in a raised position of the first frame are above that conveying plane so that articles can be transferred, in a transverse direction from the first to the second roller track conveyor.

Patent ES-475172-A1 (ES)
Title: Modular die set for blow molding containers
IPC: B29C33/30
Filed: 1978-11-07
Abstract: A modular die system is disclosed for use in blow molding an extruded plastic parison to form container members of essentially similar design but differeing dimensionally. Through use of composite die sets having modular elements, containers of different capacities can be molded without requiring complete die sets for each individual container size. That is, die elements used in molding a container member of one size may also serve in molding container members of a different size. This capability is achieved through break-down of the usual integral, cavity-defining die halves of a split die set into a plurality of die elements so selected that each of them controls but two of the three dimensions of the die cavity. Provision is made for substituting different die elements in the composite die sets and for securing these together on the platens of a blow molding press. The system simplifies tooling inventory and cost, especially in the manufacture of larger containers having a base or tray and hinged cover or lid, where the tray and lid are of congruent form but differ in their "hardware" configurations to provide non-identical but complementary hinge and latch formations, handle provisions, and the like.

A device is provided to sense the rate of flow for hydraulic fluid exhausting from the series of control valves. The rate of flow sensing device controls a pneumatic pressure regulator that provides a corresponding pressure change in the pneumatic supply pressure provided to a plurality of control valves.
Patent ES-479824-A1 (ES)
Title: Cover arrangement for a container
IPC: B63B19/19
Filed: 1979-04-23
Abstract: A cover arrangement for a container, for example for a ship's hatchway, has a cover element which is hinged at one side.

Patent ES-8403092-A1 (ES)
Title: Short circuit proof driver and alarm circuit for a solenoid in a glassware forming machine
IPC: C03B9/41
Filed: 1982-10-25
Abstract: A short circuit proof driver and alarm circuit for a solenoid actuator in a glassware forming machine is disclosed. Power to the solenoid is switched from a power source by a VMOS enhancement mode power transistor. Under normal operating conditions, the power transistor will be operated in saturation, whereby very little voltage is dropped between the drain and the source. When a short circuit condition occurs in the solenoid or connecting cable, the power transistor will be pulled out of saturation and the amount of voltage drop will become significant. Circuitry is provided for limiting current flow through the power transistor to a value somewhat above the maximum normal load current. The components of the system are selected to operate properly in the short circuit condition, thereby preventing the accidental activation of a solenoid in the glassware forming machine. A detector circuit senses the increased power dissipation across the power transistor and generates a signal to an alarm circuit to generate an alarm signal. The alarm signal can be used by an operator to determine which solenoid has failed.
