Title: Improvements in or relating to methods of manufacturing adhesives
IPC: C09J161/34
Filed: 1952-05-09
Abstract: Aqueous solutions of heat-hardenable urea-formaldehyde condensates also contain a polyhydric phenol and a primary aromatic amine. They are useful as adhesives and have an increased shelf life without an unduly prolonged hardening time. Suitable polyhydric phenols are resorcinol and phloroglucinol. Suitable amines are aniline and toluidine. Ammonium chloride may be added to reduce the hardening time of layers of the dried solutions. At least 5 gms. of polyhydric phenol and 0.05-0.07 mol. of primary amine are preferably added/100 gms. of urea-formaldehyde condensate. Examples compare the shelf lives of solutions with and without added ammonium chloride and containing aromatic amine but no phenol. They also describe experimental manufacture and testing of plywood employing solutions according to the invention, and comparing them with other solutions.

Title: Improvements in or relating to producing 2, 3, 6-trichlorobenzoic acid
IPC: C07C63/70
Filed: 1961-10-17
Abstract: 2,3,6-Trichlorobenzoic acid is made by subjecting 2,3,6-trichlorobenzonitrile to a treatment known per se for conversion of aromatic nitriles to corresponding aromatic carboxylic acids. The 2,3,6-trichloro-benzonitrile may be first converted into the carboxylic acid amide by the action of a base or a mineral acid and further hydrolysing the amide to the acid. For example, the nitrile may be treated with alcoholic alkali, preferably sodium or potassium hydroxide, to convert it to the amide, which is then treated with nitrosyl-sulphuric acid to produce the carboxylic acid. The 2,3,6-trichlorobenzonitrile may be made as described in Specification 947,167, or by treatment of a corresponding dichloronitrobenzonitrile, preferably the 2,3-dichloro-6-nitro compound, with chlorine at an elevated temperature.ALSO:A herbicidal composition contains as active constituent 2, 3, 6-trichlorobenzoic acid produced by subjecting 2, 3, 6-trichlorobenzointrile to a treatment known per se for the conversion of aromatic nitriles to aromatic carboxylic acids, for example by treatment of the nitrile with alcoholic alkali to form the amide which is treated with nitrosyl-sulphuric acid to give 2, 3, 6-trichlorobenzoic acid.
Patent ES-290109-A1 (ES)
Title: Improvements in and relating to the high pressure polymerisation of ethylene
IPC: G05B19/04
Filed: 1963-07-17
Abstract: In a process of polymerizing ethylene under high pressure in an elongated reactor the linear velocity within which is increased periodically, the integral of reaction temperature taken over the period of each pulse is compared with the integral for the preceding pulse, the next interval between pulses and/or the linear velocity during the next pulse being varied as necessary to produce a constant integral and hence amount of polymer deposition. As shown, ethylene gas and a catalyst such as oxygen are fed at 11 to a reactor 10 having a preheating zone, a reaction zone, and a cooling zone the temperatures of which are controlled by surrounding water jackets. The polymer and gas are exhausted to known processing apparatus at 16. Pulsing is controlled by an integrator-type timer 26 which is effective through a selector switch 28 and an actuator 38 to adjust an exhaust valve 14 to increase the rate of flow until a comparator 40 indicates that reactor pressure as measured by a strain gauge measuring device 24 has fallen to a predetermined value. Between pulses the pressure within the reactor is maintained constant by pressure measuring device 24 controlling valve 14 through a further actuator 36 which is rendered effective by selector switch 28. The output of a thermocouple 18 measuring the temperature within the reactor is applied to a computer 22 which integrates over the period of a pulse and stores the result for comparison with the next integration. Any difference controls timer 26 to alter the period before the next pulse and/or the setting of valve 14 during the next pulse. Several computers may be associated with differently located temperature responsive devices, e.g. 18, 18a, and the integral having the greatest deviation is automatically selected to control the reactor. Failure to correct is indicated by an alarm 43. Specifications 816,110 and 1,000,308 are referred to.

Abstract: A distributor for granular material comprises a hopper 10, and at least one boom 15 having discharge outlets for the granular material and being moveable between an aperture position and a transport position (dotted lines Fig. 1). The booms are of tubular cross-section and contain feed means 48 preferably in the form of an archimedian screw with the blades 49 formed from flexible filamentary material. The booms pivot about an axis which is transverse to the length of the boom, or upwardly or at some intermediate inclined position and the transmission driving the feed means is automatically disengaged when the booms are pivoted into the transport position. The feed means is arranged to advance material along the length of the boom and to lift material to the level of the discharge outlets 20.

The material is carried at least partially by gravity from the hopper 10 to the subordinate chamber 65 which has a series of openings similar to the openings in the booms. The material is then acted upon by the feed means, which, in the central portion of the subordinate chamber comprise a member 103a which has straight vanes. The member 103a is mounted co-axially, or approximately so, with the screw augers 48. The feeding members are arranged so as to be easily removeable.

Patent ES-434768-A1 (ES)
Title: Equipment for compensating for sensor variations
IPC: G01R17/04
Filed: 1975-02-15
Abstract: The output of the sensor whose variations are to be compensated is applied to one input of a DC amplifier whose other input is connected to an analog storage. The output of the DC amplifier is applied to a voltage-controlled oscillator whose frequency varies as a function of the voltage applied thereto. A phase detector compares the output of the voltage controlled oscillator to a standard reference frequency and furnishes a DC compensating voltage corresponding to the difference therebetween. Prior to each measurement the DC compensating voltage is applied to the analog storage thereby forming a closed loop circuit and causing the voltage controlled oscillator to oscillate at its standard frequency. At the start of the measurement the connection between the phase detector and the analog storage is broken thereby causing the DC compensating voltage present at the beginning of the measurement to be applied to the DC amplifier throughout the measurement. The frequency of the output of the voltage controlled oscillator then varies as a function of the sensed signal and is counted by a counter controlled by timing signals derived from the oscillator furnishing the standard frequency signal to the phase detector.
