Title: Method and apparatus for production of fibers from thermoplastic materials, particularly glass fibers
IPC: C03B37/05
Filed: 1969-07-09
Abstract: The production of fine fibers from a hardenable thermoplastic material in a viscous state particularly glass fibers from molten vitreous material, by dropping one or more streamlets or threads of the material onto a horizontally disposed disc-shaped body rotating rapidly around a vertical axis, at an inner radial portion thereof, whereat is provided an annular trough for the supply of material which flows outwardly from the top of the trough onto the upper surface of the body and is projected thereover in sheet form by centrifugal force over the peripheral portion of the body which is perforated with a plurality of substantially vertical orifices. An annular burner below the disc-shaped body serves as a source of hot gas under pressure which is blown upwardly through the orifices to product the material into filaments, which are thereafter drawn out into fine fibers by an annular gaseous blast directed radically and substantially horizontally above the peripheral portion of the body to turn down the substantially vertical filaments while attenuating them, which is followed by the withdrawal thereof.

Title: Circuit arrangement for the electronic control of actuating members for machine controls
IPC: G05B19/08
Filed: 1969-08-13
Abstract: A switching arrangement for control elements which initiate or terminate operation steps of a machine, the elements 18, 19 &c. are controlled by actuating transistor units 15 which are in turn controlled by combinations of switches 6 acting through transistor amplifiers 11 and the electrical connections between the switches and the transistor amplifiers and between the amplifiers and the transistor units 15, and the transistor units themselves are supported on a single plate. The connections between the switches 6 and the transistor amplifiers 11 comprise vertical and horizontal leads printed on opposite sides of the board. Resistors connecting row and column leads are soldered to the leads through holes in the plate. The amplifiers 11 are assembled in groups of four, one for each row lead 4. Resistor connections 13 are made from the row leads 4 in a second conversion matrix 2 to appropriate column leads 5 to actuate selected ones of four bi-stable multivibrators 12. The outputs of these are connected in a third conversion matrix 3, together with some of the column leads 5 of matrix 2, to energize certain inputs to transistor units 15 and thereby operate corresponding power transistors 16 connected by wires 17 to the control elements 18, 19. The transistor units 15 each comprise two similar transistor stages 36, 36a, Fig. 3, providing a signal large enough to control a power transistor 16. The switch 33 is turned on by a signal on lead 5b and off by a signal on lead 5a which, through transistor 35, nullifies the signal on lead 5b. If a short-circuit fault appears on the output, the potential of the collector of the corresponding power transistor rises. Diodes connect all these points to a bi-stable transistor pair which switches in response to a fault and applies a signal to the inputs 5a of all the transistor units, thereby protecting all the power transistors against overload.

Patent ES-430765-A1 (ES)
Title: Method for pressure casting
IPC: B22D17/32
Filed: 1974-10-07
Abstract: In the method, a shot sleeve, for receiving a metered quantity of melt through an inlet or filling opening and connected to the mold cavity, has its volume continuously diminished in such a manner as to maintain a constant communication between the space above the melt in the shot sleeve and the mold cavity for escape of all the gas or air above the melt into the mold cavity before the opening of the shot sleeve into the mold cavity is completely closed by the advancing melt. This is effected, during the shot-pre-filling phase, by an accelerated motion of an injection piston from a rest position, at which the filling inlet to the shot sleeve is open, through the shot sleeve toward the mold cavity opening. As a result of the accelerated motion of the piston, the melt spreads over the melt engaging surface of the injection piston and the formation of a standing wave is prevented. During the mold-filling phase immediately following the pre-filling phase, as soon as the melt surface has reached the casting gate leading to the mold, the metered quantity of melt is displaced through the casting gate into the mold cavity. The mold-fillling phase, which follows the pre-filling phase, may be effected in various sequences of motion of the injection piston. The device for performing the method includes a shot valve controlling the delivery of hydraulic pressure to the injection piston in a preselected manner to provide desired acceleration of the piston in the shot sleeve, and electromagnetically actuated valves, check valves, and chokes are associated with the shot valve to effect a coordinated operation thereof in controlling the movement of the injection piston.

Title: Method for through connection check in digital data system
IPC: H04Q3/60
Filed: 1975-08-08
Abstract: A digital data switch of the time-space-time (TST) type for switching pulse code modulated (PCM) data is disclosed. The switch combines a parity bit with each PCM word being switched in a conventional way to supervise the internal operation of the switch. The invention consists of a method of using such a switch for checking that a correct or intended connection is made through the switch by inserting incorrect parity with PCM words to the input in question immediately after the connection is established and checking the outlets of the switch to determine the output/s having incorrect parity. The check is made by the central control of the switch which compares the output/s having incorrect parity with the intended output/s. A simple circuit arrangement for distinguishing deliberately introduced wrong parity from through connection faults is also disclosed.

Patent ES-452570-A1 (ES)
Title: Digital cardiac pacer
IPC: A61N1/365
Filed: 1976-10-20
Abstract: A digital cardiac pacer has an asynchronous interval counter to count clock pulses to establish a stimulation interval at the end of which it produces a pulse for initiating a stimulation pulse. A control counter to which amplified naturally occurring heat pulses or stimulation pulses are applied controls the delivery of a resetting pulse to the asynchronous interval counter to reinitiate its count. If the stimulation, heart, or an interference pulse is detected during the count of a "refractory period," the control counter is reset and the refractory period is extended. If another stimulation, heart, or interference, pulse is detected during the extended refractory period, no resetting pulse is delivered, and the asynchronous interval counter continues its normal count. If during the period of time following the extended refractory period a stimulation, heart, or interference pulse is received, the control counter produces a resetting pulse to reset the asynchronous interval counter. A delay circuit between the control and asynchronous counters causes the stimulation interval to be shortened during the reception of interference pulses.

The device further comprises an activating means, which is arranged to occupy an activated condition and to be in an inactive condition and depending upon its condition to actuate the pawl mechanism for shifting of the pawl between its releasing and its locking positions. The activating means comprises a body of inertia, which is adapted under the influence of forces of inertia to be shifted from a rest position to an activated position, and a transmission element, which is designed to sense the position of the body of inertia and in dependence thereof to actuate the pawl. The transmission element and the body of inertia are supported by separate supports. The transmission element is in cooperation with the body of inertia shiftable between an activated position and a rest position under the influence of return forces.
