Title: Automatic Control for Glass Drawing Process
IPC: C03B15/02
Filed: 1968-04-03
Abstract: In a sheet glass drawing process, where the width of the sheet is dependent upon the temperature of the edges of the sheet as it is being drawn and a sheet 10 of glass of predetermined width is drawn from the surface 16 of a molten bath of glass the edges passing through and in contact with slotted members 34, 34a located near the bath surface which restrict lateral movement of the sheet edges, the lateral position of each edge of the sheet is monitored after the edges have passed through the members 34, 34a by radiation pyrometers not in contact with the edges of the sheet 46, 46a to detect variations in the lateral position of each edge which results from a change in the width of the sheet, and the temperature of each edge is automatically moderated as the sheet is being formed in accordance with the variations detected by the pyrometers 46, 46a to maintain the lateral position of each edge and thus the width of the sheet substantially constant. The radiation pyrometer receives radiation from an image area of the sheet edge, which image area occupies less than the full target area of the instrument, preferably one half thereof. The variations in radiant energy received by pyrometers 46, 46a are fed to controller recorders 50, 52 which in turn regulate the input to electrical heaters 44, 44a, located between the slotted members 34, 34a and the molten bath, to control the temperature of the sheet edges. In an alternative embodiment (Fig. 7) the heaters 44, 44a are set to supply an excess of heat, the temperature of the sheet edges being controlled by cooling air from pipes 64 connected to the control device 50, 56. In a further embodiment the sheet edge temperature is controlled by a gas burner (Fig. 8, not shown), connected to the control device 50, 56. A typical window glass composition is given in weight per cent:-SiO 2 71.38 Na 2 O 12.79 CuO 9.67 MgO 4.33 Na 2 SO 4 0.75 NaCl 0À12 Fe 2 O 3 0.15 Al 2 O 3 0À81.

Abstract: A PN junction 5 between a P-type semiconducting region 2 and a surrounding N-type region 1 is completely surrounded by an inversion channel restricting ring comprising a metal layer 9 over an insulating layer on the semiconductor surface and a high conductivity N- type region 12 below the insulating layer, the region 12 closing a discontinuity in the other wise annular shape of the metal layer 9. A further metal layer 8 extends over the region 12 through the discontinuity in the metal layer 9, to make ohmic or capacitative contact with the P-type region 2. The metal layer 9 may contact the region 12 through one or two apertures in the insulating layer, e.g. as in the Si diode shown. Alternatively the metal layer 9 may contact some other part of the semi-conductor body. As shown, the metal layer 9 directly overlies the PN junction 5, but in another embodiment it is spaced from it, overlying only the N-type region 1. In a planar Si transistor according to the invention an N-type emitter region (22), Fig. 4 (not shown), is provided within the P-type base region (21), and metal layers (25, 23) in ohmic contact with the emitter and base regions respectively extend over n+ channel-interrupting regions (31, 34) through discontinuities in an otherwise annular metal layer (28) which, together with the regions (31, 34), completely surrounds the base-collector junction (43). The metal layers may be of Al, Au or Ni, the insulating layer may be of silicon oxide, silicon nitride, glass or titanium oxide, and the diffusants for the P- and N-type regions may be respectively B and P.

Patent ES-362962-A1 (ES)
Title: Gas sampler apparatus
IPC: G01N1/22
Filed: 1969-01-27
Abstract: A gas sample is collected from a main 13 by a pumping plunger 29 reciprocated in a cylinder 31 by a diaphragm 41 permanently pressurized on its underside, the chamber 27 above the diaphragm being alternately pressurized and exhausted at a controlled rate so that a representative sample is collected. Gas admitted to the chamber 27 through a connection 18 enters the cylinder 31 through a hole in the plunger, the hole being closed by an annular seal 30 during the compression stroke. The compressed gas opens a spring-loaded lift valve 33 and flows into a line 14. The rate at which the chamber 27 is alternately pressurized and exhausted is controlled by a valve 11 which is either pneumatically operated, as shown, or solenoid operated, Fig. 7 (not shown). The valve 11 is responsive to the pressure in a line 20 connected by a passage 61 to a branch main 17. If pressure is lost in the line 20, a piston 65, 66 lifts thereby to connect the connection 18 to a vent 68 instead of to the mains branch 17. Exhaustion of the line 20 may occur after a predetermined amount of gas has passed through the main 13 as detected by a meter (100, 103), Figs. 5 and 6 (not shown). Alternatively, the exhaustion may be controlled by a timing head 12 comprising a shuttle valve 82 controlling a vent 80. The shuttle is moved by a diaphragm 74 subjected on its upper side to the mains pressure. When the piston 29 performs a compression stroke, a spring 76 lifts the diaphragm at a rate determined by the setting of a needle valve 90 in a by-pass 91, 92, 93 between opposite sides of the diaphragm.

Title: Device for blocking toll calls from subscriber telephones
IPC: H04M1/677
Filed: 1972-05-20
Abstract: To prevent the unauthorized initiation of toll calls from a subscriber station of a telephone system, the telephone set is equipped with monitoring circuitry working into a binary/decimal counter which is activated during the dialing of the first (or some other specified) digit and, in response to one or more predetermined values of that digit, trips a flip-flop to place a shunt across the line loop with concurrent generation of a busy signal. The flip-flop is also tripped if dialing is commenced before reception of a dial tone from the central office. Spurious dial pulses generated by manipulation of the hook switch, registered by the counter as a first digit but too short to actuate the switching equipment of the central office, are recognized by a detector in the monitoring circuitry and trip the same flip-flop.
Patent ES-403996-A1 (ES)
Title: Electronic braking system
IPC: B60T8/1761
Filed: 1972-06-17
Abstract: The invention relates to an electronic anti-skid system which avoids the untimely operating of the system which occurs especially further to the aleatory variations of the wheel speed. A given percentage of the output voltage of a wheel speed sensor is memorized in a capacitor by means of a diode, as soon as the wheel decelerates. The exhaust signal which is given at the output of an anti-skid logic circuitry is transmitted to a transistor only when the wheel speed has decreased of an amount equal to the complementary percentage of the given percentage. The resetting of the devices is effected by another diode which deletes the memorized voltage of the capacitor.

Title: Tracking level detector
IPC: G01R13/02
Filed: 1973-12-20
Abstract: A tracking level detector is described capable of accommodating n analog inputs, where n is an integer ranging from one to infinity, to provide an analog output equal in magnitude and electrically buffered from one of the n inputs having the largest analog value (or lowest analog value according to the embodiment chosen), as compared to the remaining n - 1 inputs. The level detector is designed to exhibit a high input impedance at the n inputs to avoid loading the inputs and minimize the current drain. Additionally, a high differential and common mode input capability is established by providing a floating bias to the level detecting circuitry. Modified embodiments include an encoder which provides an additional digital coded output corresponding to the one of the n inputs controlling the analog output. Codes of various bit lengths are implementable. The characteristic advantages of the detector are obtained by utilitizing n operational amplifiers having their negative inputs connected in parallel and tied to the analog output at a common node point in parallel with a bias voltage supply.
