Title: Improvements in or relating to the manufacture of esters
IPC: C07C69/56
Filed: 1938-01-01
Abstract: 507,778. Crotonic acid esters. DISTILLERS CO., Ltd., and STAUDINGER, H. P. Jan. 1, 1938, No. 32. [Class 2 (iii)] Esters of crotonic acid with alipliatic, cycloaliphatic and aromatic alcohols such a.s butyl alcohol, glycerol, glycol, cyclohexanol and benzyl alcohol, are made by reacting the aldehyde, alcohol and oxygen in the presence of a non-acidic oxidizing catalyst such as manganese crotonate or phosphate, or copper crotonate. The reaction may be effected by blowing oxygen or air into a mixture of the alcohol and crotonaldehyde, or the mixture may be passed downwardly through a packed tower in counter-current with hot air or oxygen, or oxygen or air and the aldehyde vapour may be passed into the alcohol. In an example crotonaldehyde, benzyl alcohol, benzene, manganese dioxide and phosphoric acid are heated in a flask and air is introduced, water being carried away by the benzene. Specifications 422,764 and 482,736 are referred to. The Provisional Specification includes the use of other similar unsaturated aldehydes.

Title: Electrode for monitoring operation of continuous casting
Inventor: YAMASHITA HIDEAKI
IPC: B22D11/16
Filed: 1980-01-07
Abstract: PURPOSE: To prevent a breakout securely and to improve the quality of a continuous casting slab, by detecting fluctuations of insulating resistance of a slag boundary film pressured between a mold and molten steel.  
     CONSTITUTION: Between electrode 1 made of a wire of W or Mo providing the protection of a refractory body layer over a steeping area in molten steel 3 in continuous casting mold 2 and electrode 5 using copper plate 4 of the mold internal wall, the voltage across constant voltage power source 6 is applied so as to detect fluctuations of the insulating resistance of a slag boundary film interposing between mold 2 and molten steel 3. For this purpose, detect-current measuring device 8 measures fluctuations of the current and current-fluctuation detector 9 compares current fluctuation value ΔA with the reference value based upon the actual result; and speed conversion value selector 10 varies a slab drawing speed finally via pinch roll speed controller 11 to vary the amount of molten steel injected into and the amount of mold power feed to mold 2, thereby preventing a break-out.

Title: Guar as drift modifier
Inventor: JIEEMUSU HEIZEN
IPC: A01N25/10
Filed: 1995-01-04
Abstract: PURPOSE: To obtain a drift control agent effective for controlling the particle size of aqueous aerial spray or the liquid particle size of discharges, esp. for minimizing spray drift. CONSTITUTION: This drift control agent as a spray drift-reducing composition comprises, in the final dilution stage, water as the major component and a single drift control agent essentially composed of 0.075-0.2 (pref. 0.075-0.18) wt.%/unit volume of guar. When the drift control agent is a noncationic derived guar (e.g. hydroxypropyl guar, carboxymethyl hydroxypropyl guar), its concentration is 0.075-0.275 (pref. 0.1-0.125) wt.%, while in the case of a cationic guar, 0.05-0.1 wt.%. The guar or derived guar does not reduce the biological action of a biological activator in a spray mixture, being favorably compatible with other adjuvants and stable to shear force.

Date Dec. 11, 1980.A system for converting a speech signal into a data signal for controlling an implantable stimulation electrode array hearing prosthesis. An input speech signal is passed through three circuit arms, comprising filter circuits, zero crossing counter circuits and RMS measuring circuits (3-13), for producing signals representing amplitude and frequency of the fundamental voicing component and the first three formants of the speech signal. Computer (14) is programmed with a patient's psychophysical data, and determines the manner of stimulation of the electrodes by ranking the sharpness of the electrodes and assigning sub-bands of the second formant frequency range to particular electrodes. Also, the voiced or unvoiced nature of the signal is determined by comparing the fundamental and second formant components. The output signal passed through a data formatter (15) and transmitter (16) has both formant and prosodic information whereby the production of confusing percepts is avoided.

IPC: H04N3/22
Filed: 1982-02-15
Abstract: A deflection generator of a television receiver is coupled to a deflection winding for generating scanning current during a deflection cycle. The generator includes a retrace capacitor coupled to the deflection winding for forming a retrace resonant circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor and another capacitor form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement is coupled to a source of energy and the second resonant circuit in a push-pull configuration. The switching arrangement is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source in the second resonant circuit. This stored energy is then transferred to the retrace resonant circuit during the retrace interval to replenish losses sustained during the deflection cycle.
