Title: Improvements in marine propellers
Inventor: COXON JOHN RICHARD
IPC: B63H3/00
Filed: 1984-12-30
Abstract: A variable-pitch marine propeller comprises helicoidal blades 6 each mounted on a hub 1 to freely pivot about radial axis 25 spaced in front, in the direction of rotation, of the center of pressure of the blade 6 whereby water pressure acting on the blade exerts a torque which tends to turn it about its axis in a direction to bring the surfaces of the blade into line with the flow of water over it. The axis 25 is also spaced behind, with respect to the direction of movement of the propeller through the water, a major portion of the pressure surface of the blade whereby, the resultant of the drag of the water exerts a torque which tends to turn the blade in an opposite direction. The shape and mass distribution of the blades relative to their pivot axes are also such that centrifugal effects tend to move the blades, in the absence of hydrodynamic forces, into a pitch equal to that of the helicoid. In operation each blade adopts a stable equilibrium position in which its pitch is optimally suited to the speed of rotation and the linear axial speed of the propeller.

Abstract: Disclosed is a method for preparing naringin dihydrochalcone through circulating spray hydrogenation, including the following steps: dissolving naringin in a potassium hydroxide solution, adding a catalyst and mixing evenly, and pumping the mixed solution into a circulating hydrogenation reaction tank; adding hydrogen after vacuumizing the tank, and performing circulating spray hydrogenation until the hydrogenation is completed; then discharging the reaction solution, and recycling the catalyst by filtration; neutralizing the reaction solution with a prepared high—concentration cold hydrochloric acid solution until the pH value is 5—6; crystallizing and filtrating the neutralized reaction solution to obtain naringin dihydrochalcone crystals, washing the naringin dihydrochalcone crystals with water and drying to obtain high—purity naringin dihydrochalcone. According to the method, the circulating spray hydrogenation technology is adopted, the contact surface between the reaction solution and hydrogen is greatly increased, the hydrogenation reaction is accelerated, the hydrogenation is more sufficient, and the hydrogenation time is shortened.
Patent NL-233029-A (NL)
IPC: H04Q1/36
Abstract: 957,198. Automatic exchange systems; magnetic storage matrices. STANDARD TELEPHONES & CABLES Ltd. Aug. 2, 1960, No. 26748/60. Headings H3B and H4K. Separate magnetic matrices are used as meter stores, Fig. 1, and as class-of-service stores, Fig. 2, for a group of 200 lines, the two stores being operated by separate pulses transmitted over leads P1 to P200 individual to the lines and common to the two stores. Time position T1, T2 and T3, T4 (Fig. 4) are allotted respectively to the class of service store and to the meter store, the time position being marked in the appropriate stores by half-write drive pulses which, unaided, cannot switch a core. A core is switched by a bias pulse, slightly longer than a drive pulse. Class-of-service indicator, Fig. 2.-Each classof-service is represented by one or more columns of cores. Lead P1 from line 1 is linked with two cores indicating that it is a call box (CB) and has a barred trunk restriction (BT). When a free register is seized by line 1, it transmits bias pulses T1, T2 of opposite polarity in succession over P1 and the two cores are switched and restored. Amplified output signals on leads CB1, BT1 act through OR gates to switch toggles CB, BT. The toggles transmit the signals to the register and are restored by a reset pulse as shown. If the registers operate one at a time, no special arrangements are necessary to steer the signal to the correct register. Meter store, Figs. 1 and 3.-Each of the leads P1 to P200 is linked with a column of six cores capable of storing up to 63 units in binary rotation. When a call has matured, the number of bias pulse pairs T3, T4 received signifies the charge. The first bias pulse T3 sets all the cores R1 to R6 to " 0 " and transfers the number n stored therein to an auxiliary store, Fig. 3, comprising toggles TG1 to TG6. The ADD pulse increases the number stored by 1 and the T4 pulse biases transistors TS1 &c. to transfer the number n + 1 to the original store R1 to R6. A reset pulse restores the auxiliary store to normal. The auxiliary store may be common to a number, say 5, of meter stores. The information may be transferred from the store to a central point for automatic accounting.

IPC: A61M16/18
Filed: 1968-10-16
Abstract: 1,221,373. Anaesthetic apparatus. O. H. DRAGER [trading as DRAGERWERK, HEINR. & BERNH. DRAGER], 21 Oct., 1968 [21 Oct., 1967], No. 49924/68. Heading AST. An anaesthetic apparatus comprises a liquid anaesthetic evaporation chamber 9 connected in a first conduit 1, 2, 5, 8, 3, 7 and 13, a bypass conduit 2, 4, 6 and 7 bypassing the chamber and a throttle 4 in the bypass conduit for regulating the relative amounts of carrier gas passing through the bypass and chamber and comprising a valve port 4a and throttling member 4b having a connecting member 23 linked by a pin 25 to spindle extension 21, the extension 21 and member 23 having different coeffiients of expansion so that the throttle is controlled by the temperature of the liquid anaesthetic in the chamber. Spindle 15 and extension 21 pass through the throttling member but are not directly attached to it. Manual adjustment of throttle 4 is by thread 19 and knob 18. The coefficients of expansion of spindle extension 21 and connecting member 23 are chosen so that as the temperature of the liquid anaesthetic falls and the vapour pressure falls consequently, the bypass throttle tends to close so that more carrier gas passes through the chamber and maintains constant the concentration of anaesthetic vapour in the carrier gas emanating from 13. A second throttle 3 may be interposed between the chamber 9 and mixing chamber 7 and connected by meshing gear wheels 16 and 17 to the spindle of throttle 4 so that as 18 is turned to close throttle 4, 3 is opened by the same amount and vice versa. The throttle 4 can be adjusted so that it closes at a predetermined temperature in the chamber 9. The temperature of the liquid anaesthetic can be sensed by a stud 26 and read on a dial 24 or the dial 24 can be calibrated to read the percentage of anaesthetic vapour in the mixture once the temperature has fallen and the carrier gas carries the saturation concentration of vapour at the liquid temperature.
