Title: Method for the preparation of modified magnesium hydroxide
Inventor: SULEV DIMITAR T
IPC: C01F5/20
Filed: 1991-04-12
Abstract: The method is applicable in the chemical and pharmaceutical industries, especially for the manufacture of high-concentrate suspension antiacidic medicaments. A product of improved antiacidic preporties and longer acid neutrailization effect in the more favourable physiological pH interval is produced. Magnesium hydroxide is suspended during intensive agitation in water. A solution of aluminium salt at atomic ratio between magnesium and aluminium from 100:1 to 10:1 is added to the suspension produced at continuous agitation and temperature range from 20 to 50°C for 10 to 90 min. There follows filtration and washing.

Title: Dual type braking system for lorry - has dynamic brake operated by same control as normal brakes
IPC: B60T11/10
Filed: 1968-12-14
Abstract: The lorry is fitted with a dynamic brake as well as a normal braking system. The same brake pedal operates both systems, using the same pneumatic control line. The brake control valve, operated by the pneumatic linkage to the pedal, is set so that for small brake pedal displacements the dynamic brake is progressively operated, while for increased pedal pressure both systems operates. A stepless fine braking control is thus possible, with the amount of pedal travel readily adjusted, and with the pedal force regulated by the relative piston areas of the control valve.

Title: Automatic balancing device for single rotor helicopter - comprises single counterweighted blade and differential unit in drive line
IPC: B64C27/10
Filed: 1969-03-20
Abstract: The automatic balancing device for a helicopter with a single powered rotor balances rotor torque and lift a symmetry. it consists of a single rotor blade (48) with a counterweight (49) mounted above the main rotor (3) on an extension of the driveshaft. A differential (50) in the drive line causes the blade to rotate in the opposite direction to the rotor. The blade drive is through the planet wheels (57) of the differential and a stubshaft (58). The rotor is driven through the upper sun wheel (59) and a sleeve (60) around the stub. The high aerodynamic resistance characteristic of the blade causes it to stop rotating at quite low flight speeds. The rotor then rotates at its full speed. The balancing blade setting can be varied by rotating it on its shaft (52) between stops (53, 54). There is a freewheel (56) in the drive line. With this in operation the balancing blade turns with the rotor, slowing the rate of descent.

The resistor may be formed by a second f.e.t, both transistors being integrated in a common semiconductor substrate. The capacity between the gate and drain electrodes may be also variable.

Title: Pre-distortion cct for three line sequential colour TV signal - designed for cct converting this signal in FBAS signal
IPC: H04N9/86
Filed: 1971-11-19
Abstract: The pre-distortion circuit applies to a three line sequential colour television signal which is converted to a light intensity signal and a FBAS colour video signal containing colour difference signals. A colour signal is repeated in the dead time points by means of line delay lines and line frequency switches. The illumination signal of the FBAS signal is produced from three sequential lines by addition of the sequential colour signals. The light intensity signal portion of the colour difference signals is brought together from a different amplitude relationship than that of the illumination signal of the FBAS signal. Colour difference signals reproducing accurate colour pictures are generated in the reproducing circuit by matrixing.

Title: Flywheel mounted ignition system for IC engine - obtains thyristor switching signal from separate pole
IPC: F02P1/08
Filed: 1972-11-24
Abstract: An engine ignition system derives energy from permanent magnets (24, 25) attached to the inside of the flywheel (2) inducing a current in a charging coil (21) on the centre limb of a three limb magnet system. This energy charges a capacitor which is then discharged rapidly through a transformer by triggering a thyristor switch in series with the capacitor and transformer primary winding. To produce a reliable triggering pulse at the correct time interval, the triggering winding (23 is placed on the pole lamb (17) which lags the centre limb with respect to the flywheel rotation (P1). This ensures that an adequately high and correctly positioned spike of voltage is available for triggering which is unaffected by motor speed. Satisfactory operation up to 14000 rev/min is claimed compared with approximately 9000 rev/min.

Patent JP-H055878-B2 (JP)
IPC: C10G35/085
Filed: 1989-02-13
Abstract: A process for the isomerization of C4-C6 paraffins with good stability and high conversion that uses a highly active catalyst to isomerize the feed (10) in the presence of very little hydrogen (14) which is selected so that the hydrogen to hydrocarbon mole ratio of the effluent (46) is 0.05:1 or less, and hydrogen is not recycled. Continued operation at low hydrogen concentrations in the reaction is made possible by the remarkably low coking tendency of the catalyst, especially during periods of temporary sulfur deactivation. The low hydrogen to hydrocarbon mole ratio feature simplifies the process and makes it cheaper to operate by eliminating facilities for the recovery and recycle of hydrogen. The catalyst comprises alumina having 0.01 to 25 wt.% of platinum, and from 2 to 10 wt.% of a chloride component. The isomerization conditions in isomerization zone (16) include a temperature of 40 to 235<o>C, a pressure of 7 to 70 barsg and a space velocity of 0.1 to 10 hr<-><1>. A chloride concentration of 30 to 300 ppm is maintained in the reaction zone (16).

Abstract: An optical modulation device is constituted by a polarizer; a first film forming a first state and a second state depending on an electric field applied thereto, the first state causing birefringence and the second state not causing birefringence respectively of polarized light from the polarizer, the first film having a thickness set for functioning as a halfwave plate in its first state; and a second film not causing birefringence of light having passed through the second state of the first film but causing birefringence of light having passed through the first state of the first film, the second film having a thickness set for functioning as quarter wave plate or a halfwave plate when the first film is set in its first state. The light from the second film is caused to enter the second film again through a reflection means or a third film selectively forming a first state causing birefringence of light which has caused birefringence and passed through the second film or a second state not causing birefringence of light which has passed through the second film without causing birefringence. The light thus modulated is then caused to enter an analyzer. As a result, an optical modulation giving a large contrast is provided by using a material having a small birefringence effect for the first film or third film.   <IMAGE>

Abstract: A medical treatment system provided with a safety device which prevents laser beams from being unnecessarily projected on a normal coeliac tissue around an affected coeliac region requiring medical treatment from a laser knife apparatus. When the operator approaches an eyepiece and is at a prescribed distance therefrom, then the safety device removes a mirror from a path of laser beams, enabling laser beams to be brought into a laser knife probe when a foot switch is closed. An infrared ray detector is provided in the eyepiece. When the operator approaches the eyepiece and is at the prescribed distance therefrom, an output signal from the infrared ray detector will be at a prescribed level. As a result, a solenoid controller is actuated to energize a solenoid. The mirror is removed from a path of the laser beams by the energized solenoid. Unless the operator approaches the eyepiece, the mirror remains in the path of laser beams, thereby preventing laser beams from being brought into the laser knife probe.
