Title: Measurement of corrosion protection
IPC: G01N17/02
Filed: 1975-10-11
Abstract: 1493695 Evaluating corrosion protection TEXACO BELGIUM NV SA 11 Oct 1975 41717/75 Heading G1N Corrosion protection of a metal against a corrosive fluid by a passive film or an inhibitor in the  fluid is determined by providing a pulsed current of less than 100 ÁA peak and a pulse repetition frequency of at least 1 KHz between a working electrode mode of the metal and an inert electrode, both immersed in the fluid and, measuring the current and determining the solution capacity at the interface between working electrode and fluid and optionally the solution resistivity. Preferably inhibitor is added in stages to the fluid and the current/impedance continuously monitored. The capacitative and resistive effects can be separated by measuring at two frequencies e.g. 10 and 100 KHz. The current pulses are supplied through a high resistance R to inert electrode 11 and working electrode 10 to keep the current below 100 ÁA, the value of R being much greater than the solution resistance to enable simplifications to be made in the equations for calculating resistance and capacitance. The cell current may be monitored on an oscilloscope 18 and amplified and recorded at 17. A reference electrode 12 (e.g. calomel) may be provided for measuring D.C. corrosion potential.

MO. A multivibrator Gf1  tuned to the given frequency is coupled to the input so that if the given frequency is present in the input the multivibrator locks on to the frequency and phase of the input aided by coupling capacitor CK, and if the given frequency is present in the input the multivibrator biases the ring modulator so that it full wave rectifies the signal. The output of the ring modulator feeds a summing circuit SU which in turn feeds a threshold device SD. If the given frequency is present an output is obtained at AS. An initial limiting amplifier may be used and the summing circuit and threshold device may be replaced by a delay line. If more than one frequency is to be detected, a series of multivibrators Gf 1 -Gfn may be connected in turn to the modulator MO by means of switch AT1, Fig. 3a. The outputs of the modulator for the different multivibrators are fed to summing circuits SU1-SUn by switch AT2. The outputs of the summing circuits are fed in turn via switch AT3 to threshold device FD, the output of which is fed via AND gates U1-Un, to output terminals AS1-ASn. Summing circuit SUb monitors the whole signal bandwidth and prevents errors arising at the commencement of the signal during short -measuring times.

Title: Production of malt beverages
IPC: C12C7/00
Filed: 1960-12-16
Abstract: In the production of brewed malt beverages such as ale or beer for packaging, the foam stability of the beverage is enhanced and development of cloudiness on storage is minimized by treatment involving a peroxidase catalysed oxidation of precipitable constituents of the brew in the presence of hydrogen peroxide and filtering or centrifuging off the precipitate formed by such oxidation.  The peroxidase may be from the malt employed, and may be supplemented by peroxidase derived from horseradish, malt sprouts, or ficin.  The hydrogen peroxide, or a substance generating hydrogen peroxide, may be added to the wort, in the concentration 10-100 parts per million, before it is boiled, or the hydrogen peroxide in concentration 20-100 parts per million and peroxidase in a concentration of at least 1 part per million may be added to boiled wort.  Alternatively, the brew after fermentation may be treated with 0.05-0.5 parts per million of purified peroxidase and 1-10 parts per million of hydrogen peroxide.  A proteolytic enzyme-containing chill-proofing agent may be added to the beverage before packaging. U.S.A. Re-issue Specification 23,523 is referred to.

Abstract: 1,214,750. Cutting apparatus; seaming non- metallic sheet material. A. CANTELOUBE. 13 Sept., 1968 [27 Sept., 1967], No. 43576/68. Headings B4B and B5K. [Also in Divisions B3 and F4] The invention relates to a process and an apparatus in which two strips, which may be P.V.C. strips, 1 and 2, Fig. 6, are rolled together after printing a tube-circuit A on strip 2 in a stop-weld material and the composite strip 10 produced is sheared, 9, into panels 14, and in which a marking is made on strip 2 prior to rolling but before shearing, the shearing operation being controlled as a function of the length of strip delivered after detection of the marking. The marking may be a punch-hole in strip 2 detected by a mechanical probe, Fig. 17 (not shown), or an insert of a material having a composition different from that of the strip and detectable by means of a magnetic, X-ray, Fig. 22 (not shown), or an ultrasonic detector, Fig. 23 (not shown). In certain cases the stopweld material may constitute the marking by being opaque to X-rays or including a radioisotope of short half-life detectable by means of a Geiger or scintillation counter. The shearing station, Fig. 20, comprises fixed speed feed rolls 193, continuously feeding the composite strip 10 into a region U in which a loop 10a of the strip may be formed, staggered feed rolls 196 operable at two speeds, fast and slow, the fast running speed being sufficient to take up the loop 10a, a length measuring device 42, a detector 17 and a crank and eccentric operated shear blade 12. The rolls 196 are driven at their two speeds by a fast constantspeed motor 198 and a slow speed motor 199 through a clutch member 210. With the strip at high speed the marking is detected by detector 17d 1  which switches the rolls 196 via clutch 210 to slow speed running. The mark is then detected by detector 17d 2  which engages the measuring device 42, which comprises a friction wheel 206 driving a magnetic sprocket 207 in front of a magnetic core 208 wound with a coil 209 which emits a series of pulses on rotation of the sprocket. When the number of pulses corresponding to a predetermined length has been received by a comparator (18), Fig. 1 (not shown), the motor 199 is stopped and the shear actuated.

[Also in Division G1] In a tachometer for measuring the R.P.M. of an I.C. engine by means of a monostable blocking oscillator fed with pulses from the engine induction coil, the lead in the L.T. side of the coil is coupled to a saturable toroidal core 11 carrying windings 12, 13 which are connected with a transistor 18, causing collector current with each break, which is averaged by meter 25. Each cessation of current in primary winding 14 causes the positive core flux to drop, inducing a voltage in winding 12 which produces conduction in transistor 18, and the current through winding 13 escalates to produce core saturation in the negative direction. A current pulse thus passes through meter 25. When the contact breaker recloses the initial conditions are restored. Thus the average current indicated by meter 25 represents R.P.M. Temperature compensation is effected by thermistor 17, and the circuit is substantially independent of voltage variations.
