Title: Machine for thinning and hoeing rows of plants
IPC: A01B41/06
Filed: 1968-07-26
Abstract: A machine for thinning and hoeing rows of plants, has hydraulically operated rotatable tool discs 34 with rigid radial hoeing tools, an electrical contact plant feeler 45 behind each tool disc and a control valve 61 for the hydraulic motor 30 of each tool disc, mounted in the return pipe 32 thereof and actuated by a control device containing the feeler circuit. Each tool disc is mounted on or indirectly connected to, the driving shaft of a hydraulic motor (30), Fig. 4 (not shown), the feed pipe to which maintains a constant predetermined fluid pressure by virtue of a pressure storage loading device 48, located between pump 47 and storage device 49, Fig. 5, or by means, Figs. 7 and 8 (not shown), of an excess pressure valve (56) and electromagnetically controlled hydraulic valve (67). The hydraulic motor control valve 61 and control device therefor are shown in Fig. 5 prior to contact of a plant with the feeler 45, in which position valve 61 is closed and disc 34 therefore stationary. The valve 61 is switched on by completion of the feeler circuit through a plant to actuate electromagnetic switch 62 and is switched off by means of a magnetic reed contact unit 97, actuated by a magnet 99 disposed on the rotor disc limb 37, the sequence being controlled by high resistance relays A, B, C controlling a series of contacts a 1 , b 1 , c 1 &c. The length of the hoeing path (H), Fig. 10 (not shown), may be varied, for a given speed of travel, by adjusting the hydraulic fluid pressure.

Title: Process for providing metal components with coatings resistant to corrosion
IPC: B23K20/22
Filed: 1968-11-13
Abstract: Stripped or pickled components made of one or more of the metals Zr, Ti, Hf, Ta, Nb, V or their alloys are provided with a coating resistant to corrosion at high temperatures by a process comprising zinc plating a member made from an alloy based on Al-Si and brazing the member using a metal chosen from Cu, Ag, Be, Ge, Si or their alloys to a surface of the component to be protected. In coating the interior of a tube, the tubular Al-Si alloy member may be pressed against the interior surface of the tube using a mandrel whose coefficient of expansion exceeds that of the tube. Brazing may be performed at a temperature of 380 to 660 C. maintained for at least an hour under a pressure of at most 10-3 torr. The Al-Si alloy member may contain one of the metals of the component. In an example, a tube of Zr-alloy containing: was coated with a tubular member of Al-Si alloy containing 1% Si, the member being first zinc plated by immersion in aqueous sodium zincate and then copper plated electrolytically in a bath based on sodium cyanide. The tubular member was placed inside the Zr-alloy tube and an oversize knob forced through the member, following which a core of austenitic steel was placed inside the member and the assembly heated for one hour at 615 C. under vacuum. The joint is stated to comprise a diffusion region in which a layer of an intermetallic Al-Si-Zr compound is formed. On another example the core was of alumina-aluminium.
Patent ES-361861-A1 (ES)
Title: Electronic phasing system
IPC: H04N1/36
Filed: 1968-12-26
Abstract: First and second signals of the same nominal frequency are brought into phase by periodically producing a pulse whose duration corresponds to the phase error, producing a first ramp signal having the same duration as the pulse followed by a second ramp signal of opposite slope which is generated until a reference voltage level is reached, and producing a correcting signal during the time that both ramp signals exceed said reference level, and using said correcting signal to change the frequency of said first signal by a fixed amount for the duration of the correcting signal. The invention is applied to the initial synchronization of a facsimile receiver 11 with a transmitter 10, both of which are driven by local crystal oscillators. Pulses from each machine are produced by contacts revolving with the read/write head turrets, or by magnetic or capacitive pick-ups, and these, termed " backstroke pulses," are compared in a circuit 28 in which they respectively set and reset a flip-flop which thus produces pulses whose length represents the phase error. During each pulse a capacitor is charged either by a constant current circuit (Fig. 5, not shown) or a constant voltage circuit (Fig. 8, not shown), following which it is discharged (at constant current in Fig. 5) either until the next error pulse is received or until it is discharged to the reference (e.g. ground) level. During the time that the charge is above the reference level a rectangular correcting pulse is produced. Thus, this correcting pulse is produced once during a " sampling " period corresponding to the-rotational speed of one of the turrets (e.g. twice per revolution when the pickups are spaced 180 degrees apart) and has a duration proportional to the error up to a maximum corresponding to the sampling period. This pulse lowers the frequency of the receiver oscillator by a fixed amount for the duration of the pulse and this is chosen so that synchronization cannot occur in one step. This is to prevent overswing and allows for a practical acceleration rate. The constants of the capacitor circuit are selected so as to produce a correcting pulse of approximately half the duration needed to correct the error fully on each occasion. It is thus necessary only to correct for phase lead at the receiver, but an inverse arrangement could be provided to correct for lag also. The facsimile transmitter and receiver are identical machines whose respective read or write heads are selected by switching. The a.m. information signals are converted to f.m. for transmission via a standard telephone instrument and line, and are converted back to a.m. to operate the receiver. The start of transmission of information is delayed for 15 seconds for synchronization.

The elongate element is secured in the deformed position at least until the beating up of the next weft thread and then the elongate element is withdrawn from the second shed whereby, in consequence of its resilient deformability, the elongate element returns to its initial undeformed shape. Apparatus for carrying out the method is also disclosed.

Title: Process for the preparation of propylene oxide
IPC: C07D301/14
Filed: 1976-04-28
Abstract: Process for continuous production of propylene oxide (FIG. 1) from propylene and aqueous hydrogen peroxide. The aqueous hydrogen peroxide is first reacted with propionic acid in the presence of acid catalyst to form perpropionic acid (1). The perpropionic acid is taken up by extraction in benzene (5 , 12), and following drying of the benzene solution (16), the perpropionic acid in the solution is reacted with propylene (18) for oxidation of the propylene to propylene oxide and conversion of the perpropionic acid back to propionic acid. The reaction mixture is worked up to separate propylene oxide, propionic acid and benzene (25, 27, 31, 33), and the latter two are recycled. In the benzene extraction (5, 12), an aqueous raffinate (7) is formed containing hydrogen peroxide and acid catalyst. Water is removed from the aqueous raffinate (8) and the concentrate is recycled to the propionic acid reactor. Make-up hydrogen peroxide can be added to the aqueous raffinate before the removal of water.

Title: Solar radiation heat exchanger - consists of low cost panel with water in circulation channels covered to reduce ratio of emitted to incident radiation
IPC: F24S10/50
Filed: 1977-06-08
Abstract: A solar heat exchanger consists of a panel, one surface of which receives solar energy. That surface has parallel V shaped grooves which extend over the length of the panel. Three sheets of plastic are laid over one another on the surface and form outer, intermediate and inner spaces, extending over the length of the grooves, and bounded by the walls of the grooves and the sections of the sheets extending over them. The outer and intermediate spaces contain air. The inner spaces, of triangular section, constitute channels through which water circulates, and which connect with gutters at the ends of the panel. Pipes connected to the gutters feed water and take it away. The water receives radiations after they have passed through the sections of sheets and the outer and intermediate spaces. The collector is simple to construct and can be readily dispatched, stored and installed at low cost, whereas the costs of existing collectors prohibit their wide use. It collects incident light of all wavelengths and emits only a small quantity of radiation. The temp. can be controlled preventing damage if fluid circulation is interrupted. Conversion of incident energy is considerably greater than with existing panels.
