Title: Method for the preparation of vitamin E concentrate
Inventor: SHIBUE AZUMA
IPC: A61K36/00
Filed: 1983-08-31
Abstract: The invention provides a very efficient method for the preparation of a vitamin E concentrate from fresh plant tissues containing the compounds. The method includes extraction of the vitamin E compounds contained in finely ground plant tissues freed from juice with a non-polar organic solvent not miscible with water and capable of forming an azeotropic mixture with water with simultaneous removal of free water by azeotropic distillation and ion-exchange purification of the thus extracted vitamin E compounds with an anion exchanger. A concentrate containing more than 70% of the vitamin E compounds can readily be obtained which is, when leaves or stalks of the plants belonging to the families of Gramineae or Palmeae are used as the starting material, particularly rich in the content of  alpha -tocopherol.

Patent GB-2130097-A (GB)
Title: Female urinary appliance
Inventor: HALL KENNETH F
IPC: A61F5/44
Filed: 1983-11-14
Abstract: An improved female urinary appliance includes a mouth surrounding a urine-receiving cavity, and a drainage channel integral with the backside of the device and communicates with a bore opening from said cavity. The device includes means for preventing the drainage channel from kinking. The mouth is adapted to be positioned within the labia folds of the user, in contact with the vestibular tissue around the meatus and held in place by gentle vacuum. A valve is preferably used in combination with the appliance, and includes an inlet and an outlet, for maintaining a preselected vacuum condition at the valve inlet and a predetermined pressure condition at the valve outlet is disclosed. In preferred use, the drainage channel is suitably connected in spaced relation to the valve inlet. The valve contains a flow control element adapted to control flow of urine from the cavity. While the mouth is held against the vestibular tissue by gentle vacuum, urine flowing through the appliance and valve entrains gas present in the cavity. In the cavity, a desired vacuum condition is maintained, over time, because the valve includes a semi- permeable membrane adapted to permit air and other gas to diffuse through a portion of the valve and thereby to counteract the effects of entrainment and relieve or maintain the vacuum condition at a predetermined level. <IMAGE>

Filed: 1984-09-28
Abstract: A hammer drill with an air cushion impact mechanism has a latch device, comprising a resilient annular body (50; 50a), for the ram (27), and an annular resilient damping element (50; 50b) for damping the recoils of the beat piece (29). The annular body (50; 50a) and the damping element (50; 50b) are located within the rotationally driven spindle (39) of the tool bit holder (3) in a plane normal to the spindle axis, and are held against axial displacement between an annular plate 51 and a washer 52 (51,52) common to them both. The latch device and the damping element are preferably O-rings, one inside the other, and may be integral (50) or separate (50a and 50b). The damping element (50b) is preferably thicker axially than the latch device (50a). Recoil blows from the beat piece are transmitted to the plate 51 and from there to the member 50 which is compressed to damper the blow. At idle the ram 27 moves forward sufficiently for the inner ring of the member 50 to engage a groove 35 of the ram 27 to latch the ram. <IMAGE>

Title: Circuit arrangement for controlling and monitoring electrical loads
Inventor: ARNOLD KARLHEINZ
IPC: H02H3/087
Filed: 1984-12-17
Abstract: A micro computer 15 applies variable width control pulses to a switch 12 in series with a load 10 and a current measuring resistor 16 which is connected to two threshold value switches 17, 18 set to different response values. The switching state of the first threshold value switch (17), operating as a short-circuit sensor, is interrogated at a first instant of each control pulse, and the control pulse is immediately switched off upon response of the said threshold value switch. The switching state of the second threshold value switch 18, operating as an overload current sensor, is interrogated at a second instant of each control pulse, and the width of following control pulses is reduced by a fixed amount upon response of the said threshold value switch. Micro computer 15 may keep the switch 12 turned off if a short circuit persists offer a predetermined number of control pulses, a short-circuit indicating signal being also produced then. The load 10 may be a solenoid controlling fuel flow in an internal combustion engine. The microcomputer 15 adjusts the width of the control pulses applied to the transistor 12 in response to an engine speed signal at input 15e. <IMAGE>

Patent GB-2172161-A (GB)
Title: High voltage solid state switch
Inventor: CONRAD GEORGE M
IPC: H03K17/10
Filed: 1986-02-25
Abstract: A high voltage switching circuit 32 electrically couples, or decouples, a high voltage power supply 44 to, or from, a crossed field amplifier 30 selectively in accordance with a control signal from a trigger system 28. The circuit 32 converts the control signal to a radiant energy signal from LEDs 481 to 48N. A plurality of switching modules 421 to 42N serially coupled between the amplifier 30 and the high voltage power supply 44 has in each one of such modules drive circuitry 56,66 for converting the radiant energy into drive signals for parallel switching transistors 72a,72b which drive these transistors between a conducting and non-conducting condition selectively in accordance with the drive signal. With such arrangement, each of the modules 421-42N develops its own drive signal in response to the radiant energy signal so that each drive signal is self-referenced to the reference potential of the module. <IMAGE>

Patent GB-2177542-A (GB)
Title: Charge coupled device image sensors
Inventor: BURT DAVID JAMES
IPC: H01L27/148
Filed: 1986-06-25
Abstract: A frame transfer buried channel CCD image sensor incorporating an anti-blooming drain structure (25, 27) wherein accumulation of charge of opposite polarity to that drained by the anti-blooming drain structure is prevented. This can conveniently be achieved by arranging for the buried channel diffusion (19) in each channel to stop short of the anti-blooming drain diffusion (25) on one side of each channel. As a result of the prevention of charge accumulation the anti-blooming drain structure remains effective with optical overloads much greater than the optical overload at which anti-blooming performance begins to deteriorate in conventional buried channel CCD image sensors. <IMAGE>

Filed: 1987-09-07
Abstract: A signal for transmission is compared 12 with a prediction signal to produce a prediction error signal which is amplitude limited 8 and compressed 14 before transmission in analogue form. The limiter output is added 26 to the production signal and the resultant applied to a prediction function circuit 24 to generate the prediction signal.

Title: An optical disc cartridge and a mechanism for preventing an incorrect insertion of a cartridge
Inventor: OTSUKA YASUO
IPC: G11B23/03
Filed: 1988-07-12
Abstract: A disc cartridge 100 has a shutter 101 opened automatically by a swinging arm 202 as the cartridge advances into a reproducing apparatus 200, the arm 202 lying beneath a stop 206 when the cartridge is fully inserted but, if the arm 202 jumps on top of the shutter and fails to open it, the arm abuts the stop 206 and by preventing full insertion prevents displacement of arm 203 and energisation of the disc motor. A bevelled corner 105 of the cartridge meets abutment 201 on full insertion so that if the cartridge is inserted wrong face up the non-bevelled corner will meet 201 and prevent full insertion. Alternatively, the cassette can have a notch on its leading edge in a position such that when insertion is wrong face up the shutter opening arm is engaged and trapped by the notch to prevent complete insertion.
