Patent ES-8305124-A1 (ES)
Title: Flow meters with an axial turbine.
IPC: G01F1/12
Filed: 1982-06-22
Abstract: In order to compensate the hydrodynamic pressure on the turbine of a flowmeter, means are provided to create a zone of reduced pressure of constant value upstream of the turbine hub, together with means for creating a zone of pressure, on the downstream face of the hub, varying in a defined manner as a function of the axial position of the turbine. The pressure difference thus created on either side of the turbine hub produces a reaction force tending continuously to balance the hydrodynamic pressure of the fluid whatever the flow rate. The invention is particularly applicable to high flow rate water meters.

Patent ES-8406246-A1 (ES)
Title: Gripper feeding device for band or wire.
IPC: B21F23/00
Filed: 1983-12-07
Abstract: This invention relates to a gripping feeder for an intermittent feeding of strip or wire stock in presses, stamping machines or similar machines. It is an object of the invention to provide such gripping feeder which permits a change of the stroke length to be effected from the outside while the machine is in operation and permits such change to be effected manually or by means of an adjusting motor and also permits an automatic adaptation of the feeding and retaining grippers to the thickness of the strip or wire stock to be fed. This is accomplished in that the carriage carrying the feeding gripper is adapted to be driven from the main drive of the machine via a feed rocker, which extends transversely to the direction of travel of the carriage and is fulcrumed on a slider, which is slidable along a rail that extends transversely to the direction of travel of the carriage so that an adjustment of the slider along said rail will result in a change of the stroke length of the carriage. The feed rocker fulcrumed on the slider is preferably adapted to have an oscillating angular motion about its fulcrum imparted to it by a pivoted finger, to which an angular oscillation is imparted from the main drive, and which is pivoted to one arm of the feed rocker, the other arm of which is connected to the carriage by a link for imparting a reciprocating linear movement to the carriage.
Patent ES-8506176-A1 (ES)
Title: Recovery apparatus.
IPC: H01B15/00
Filed: 1984-07-12
Abstract: An apparatus for and a method of extraction reinforcements from reinforced cable is described.

A subsequent engagement between gears imparts further deformation sufficient to cause fracture of the reinforcement. A tool attachment for the apparatus comprises an elongate member having a passage for the reinforcement and a tapered end portion which causes the outer strands of a centrally reinforced cable to spread as they are pulled over the end portion. The tool is preferably used in combination with a cutter which cuts the strands after they have been pulled over the end portion. A blade may also be attached to the tool to co-operate with the cutter.

Title: Electronic contacts and associated devices.
IPC: H03K17/56
Filed: 1984-09-19
Abstract: High voltage electronic contacts (S, S min ) and associated devices including TRIMOS (MOS TRlacs) devices connected in anti-parallel fashion between two terminals (S1/S min 2, S2/S min 1). Each electronic contact (S, S min ) is controlled via a control terminal (S4) by two auxiliary electronic contacts (NA, NB) each able to establish a low or high impedance between the control terminal (S4) and one of the two other terminals (S1/S min 2, S2/S min 1), the impedance conditions of these auxiliary contacts (NA, NB) being opposed. A power protection circuit associated to the TRIMOS device allows the flow of a relatively high current through the electronic contacts (S, S min ) for the lower voltage range across it, and minimizes the power dissipation in the contacts in the higher voltage range, i.e. when abnormally high signals are applied to the contact.

Title: Microcomputer controlled repertory dialer.
IPC: H04M1/2747
Filed: 1986-05-29
Abstract: Telephone numbers and names or other associated data are stored in the memory of a microcomputer system programmed to control a repertory dialer. In response to keyboard entry of a name, the name and its associated telephone number stored in memory are displayed, and the telephone number may be automatically dialed. Headings, such as "Monday calls," are stored in the memory alphabetically and associated names and telephone numbers may be grouped under each heading. A number of "special" telephone numbers are also stored in memory to be accessed directly and dialed in response to a "special" key on the keyboard. The particular one of the special telephone numbers directly accessed by that key is keyboard-alterable using software selection data. Editing and parity checking of keyboard entered data assist the user in developing a directory for storage in the memory. The contents of the memory can be transferred to another like repertory dialer or compatible terminal or other auxiliary unit through an external data port, by which the memory can also be loaded from a remote source. The dialer includes additional novel circuitry to provide automatic timing of calls, concatenation of telephone numbers such as for discount or alternative long distance service and software controlled time of day display. Dialer operation is customized by each user via the keyboard during a setup mode of operation.

IPC: C12N15/80
Filed: 1988-04-15
Abstract: The present invention comprises novel DNA compounds that encode isopenicillin N synthetase and also comprises related methods, transformants, and polypeptides. The novel isopenicillin N synthetase-encoding DNA, together with its associated transcriptional and translational activating sequence, was isolated from Cephalosporium acremonium and cloned into an E. coli cloning vector.

The intact C. acremonium isopenicillin N synthetase-encoding DNA and associated transcriptional and translational activating sequence have also been used to construct C. acremonium expression vectors that drive expression of the isopenicillin N synthetase in C. acremonium. The C. acremonium transcriptional and translational activating sequence has further been fused to a hygromycin phosphotransferase-encoding DNA segment and placed onto C. acremonium expression vectors. Useful derivatives of the novel compounds and vectors are also described.
