Title: Fluid pressure control valve assembly for automotive braking system
IPC: B60T8/28
Filed: 1981-01-14
Abstract: A flow restriction (32) is provided in a fluid inlet passageway (8) of a fluid pressure control valve assembly for use in the fluid-operated braking system of an automotive vehicle, wherein a valve housing (1) is formed with a valve chamber (24), first and second fluid ports (8a, 19a) open to the valve chamber (24) and first and second fluid passageways (8, 19) respectively leading from the first and second fluid ports (8a, 19a) and wherein a ball (25) responsive to deceleration of the vehicle is movable in the valve chamber (24) into and out of a position closing the second fluid port (19a) and thereby entrapping a fluid pressure in the second fluid passageway (19) during sudden deceleration of the vehicle. The first fluid passageway (8) is formed with the flow restriction (32) smaller in cross-section than the first fluid port (8) so that the fluid pressure in the valve chamber (24) is increased at a limited rate when the fluid pressure supplied to the first fluid passageway (8) is increasing. <IMAGE>

Title: Torque transmitting device
IPC: F16H35/00
Filed: 1981-06-25
Abstract: An inertia member (28) is rotated, by a drive element 11 with a fluid-filled housing 13 about the axis of rotation of the element. Depending on the centrifugal force acting on the member (28), the rotary movement of drive element (13) is transmitted to a driven element (12). In order to permit a slip of 0% to 100% between these two elements, (12, 13), member (28) is coupled to a crankpin (27) or eccentric connected to driven element (12) and non-return valve 20, port 24 with member 28 and passage 29 are provided to prevent the centrifugal force (31) acting on rotating inertia member (28) at least partially from exerting a torque on driven element (12) through the crankpin (27) or the eccentric, in a predetermined component range of the relative torsional position between elements (12, 13). <IMAGE>

Title: Anthracycline glycosides
IPC: C07H15/252
Filed: 1981-11-19
Abstract: There are provided 4'-deoxy-3'- epi-daunorubicin, 4-deoxy-3'-epi- doxorubicin and pharmaceutically acceptable salts thereof of formula   <IMAGE>  where R is H or OH. These have anti-tumour properties. 4'-Deoxy-3'-epi-daunorubicin is prepared from 3'-epi-4'-keto-N-trifluoracetyl- daunorubicin by reduction of the 4'-keto group with sodium borohydride to the corresponding 4'-hydroxy group, reaction of the resultant intermediate with trifluoro- methanesulphonic anhydride followed by treatment with n-tetrabutylammonium iodide to give a 4'- halo derivative which is reductively dehalogenated by treatment with tributyltin hydride to 4'-deoxy-3'- epi-N-trifluoracetyl-daunorubicin. Mild alkaline hydrolysis removes the N-protecting group to give 4'- deoxy-3'epi-daunorubicin. This may be transformed, via its 14- bromo derivative, to its doxorubicin analogue.

Title: Color television signal conversion device
Inventor: KUSAKABE TETSUO
IPC: H04N9/87
Filed: 1983-03-18
Abstract: Color TV signal data picked up from an NTSC video disc 48 is separated by a separation filter 50 into a first chrominance signal (1.52 MHz) and a luminance signal. In this case, the rotational frequency of the video disc 48 is set such that a horizontal line frequency of the luminance signal is 15.625 kHz which is the line frequency of the PAL signal component. The first chrominance signal (1.52 MHz) is converted by a frequency converter 53 to a second chrominance signal (4.43 MHz). The second chrominance signal (4.43 MHz) is supplied to the first input terminal X1 of a switch 66 through a 45 DEG  phase shifter 64 and directly to the second input terminal X2 of the same switch 66. The switch 66 selects the first input terminal X1 in response to a burst gate pulse, and selects the second input terminal X2 during any period other than the burst period. The third chrominance signal is supplied to an R-Y component processing circuit 81. A carrier signal having a frequency (8.86 MHz) twice that (4.43 MHz) of a subcarrier is supplied to the R-Y component processing circuit 81. The R-Y component processing circuit 81 performs an analog multiplication operation, thereby producing a PAL chrominance signal at its output terminal. In a further embodiment a system changeover circuit (78,79, Fig. 8) is provided so that either a PAL or NTSC recorded video disc may be played back. In addition a played back PAL signal may be converted to an NTSC signal. <IMAGE>
