Patent ES-337374-A1 (ES)
Title: Circuit arrangement for correcting a television signal
IPC: H04N5/208
Filed: 1967-02-28
Abstract: When a television signal V, Fig. 1 is fed into and then read out of a magnetic recording or like device 2, the signal is found to have had its low frequencies much attenuated and its D.C. level removed. Such an alteration of the television signal V may be understood by giving device 2 a transfer function W, such that the altered output at 4 is VW. In a prior art arrangement, to recover the original signal V, the signal VW is fed to a low frequency amplifier 5, having the transfer function 1/W , such that its output may be represented as V*, i.e. corrected for the low frequency attenuation, but still without any D.C. level. The D.C. level is thus replaced in a clamp 6 controlled by clamping pulses, frequency fc, having unity transfer function for video frequencies, whereby the original signal V is recovered at the output 8. A low frequency noise signal S (frequency fs << line frequeney fc), Figs. 2a, 2b, appearing at the output of device 2, become S/W at the output of amplifier 5. Since fs << fc, clamp 6 acts on the noise to produce the output shown in Fig. 2b. The clamp 6 with respect to the noise, thus has a transfer function Signal S/W at the input of the clamp 6 thus becomes S[alpha]/W at the output thereof. The signal to noise ratio at the output, is thus VW/S[alpha]. At low frequencies however (i.e. frequencies of S) W is << 1, such that the low frequency signal to noise ratio is very poor. In one embodiment of the invention Fig. 3, the output television signal V 0 , is fed through a positive feedback network 11 having a transfer function (1-W) to produce a signal V 0 (1-W). This is combined in adder 10 with the output VW of device 2, to produce a signal VW+V 0 (1-W) of the input to clamp 6. Since clamp 6 has no effect on the video frequencies, then V 0 = VW + V 0 (1-W), or V 0 = V. Thus the original television signal is recovered. The noise output S 0 becomes S 0 (1-W) at the output of network 11 and is combined in adder 10 with the noise signal S, to give S + S 0 (1-W) at the input to clamp 6. Clamp 6 operates on the input noise to produce Thus Since for S, however, W<<1 S 0 #[alpha]S. The new signal to noise ratio is V/S[alpha] , an improvement by a large factor 1/W at low frequencies over the prior art. An additional low frequency amplifier stage 12, Fig. 4 (not shown), may be added having a transfer function W1, whence the transfer function of network 11 ideally becomes (1- WW1) or in practice (1-W1). If the transfer function of network 11 becomes (1-W/A) then the output signal to noise ratio becomes AV/S[alpha]. A transistorized embodiment of Fig. 3 is given, Fig. 7 (not shown).

Title: Device for drawing parallel strips with uniform tension
IPC: B65B41/12
Filed: 1970-06-17
Abstract: A wide web of heat-sealable plastic material, continuously unwound from a supply roll, is slitted longitudinally into a plurality of parallel strips which are entrained by a motor-driven traction roller and are allowed to hang in slack loops about one or more horizontal bars carried on the free end of a sensing lever, being then fed past an intermittently operating clamp and a drawing mechanism to an output stage where they pass through a set of friction rollers or rods and are periodically pulled forth for shaping into envelopes sealed about materials discharged from respective dispensers. With the drawing mechanism intermittently picking up the slack of the loops, the length of the shortest loop controls the position of the sensing lever which, on swinging beyond an upper or a lower limit, coacts with one of two stops to accelerate or retard the drive motor, thereby maintaining a proper average feed rate.

Title: Modular tubular solar energy collector apparatus
IPC: F24S10/70
Filed: 1977-10-29
Abstract: The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold. The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configurations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes. The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space. Solar energy collected on the absorber surface of the inner glass tube wall is transmitted to the U-tube and liquid therein. The U-tube within the collectors is blackened and non-reflecting. Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer. The heat transfer liquid is entirely within a closed circuit, which avoids leaks, reduces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems.
