IPC: F16D3/19
Abstract: 1,084,240. Damped resilient couplings. REGIE NATIONALE DES USINES RENAULT. Dec. 30, 1964 [Jan. 9, 1964], No. 52896/64. Heading F2U. A damped resilient connection between driving and driven members comprises three couplings in parallel, namely a lost-motion spline coupling, a spring coupling and a friction coupling forming the damping device. The arrangement is particularly advantageous in vehicles for reducing the transmission of torsional fluctuations from the engine to components coupled thereto when in neutral. As shown in Fig. 1 a clutch hub 8 has a lost-motion spline connection with a sleeve 12 rotating with a driven shaft 14. A spring 16 has its ends fast respectively with the sleeve 12 and with a cap 15 fixed to the clutch hub 8, the spring serving to connect these parts torsionally and to urge the sleeve and hub together to compress a friction lining 21 between end surfaces 23, 22 thereof to provide friction damping. In Fig. 3 a modified arrangement forms a damped resilient connection between driving and driven shafts 25, 27, a sleeve 12 being splined at 13 to the shaft 25 for rotation therewith and having a lost-motion spline coupling 11 with the shaft 27. The sleeve 12 is formed with an internal conical surface 28 frictionally engaged by a conical surface of a sleeve 29 fast with the shaft 27 to provide friction damping. A spring 16 urges the conical surfaces into engagement and torsionally connects the sleeve 29 to a ring 30 which is in screw-threaded engagement with the sleeve 12 and locked thereto by a pin 31.

Abstract: 1,230,406. Saccharification of starch. HAYASHIBARA CO. 18 April, 1968 [18 April, 1967], No. 18492/68. Heading C2C. [Also in Division C3] In the saccharification of a liquefied starch syrup, isoamylase or a mixture thereof with α-amylase is added during or after saccharification to give a reduction in viscosity without loss in heat stability of the product. It is stated this is due to hydrolysis of α-1,6 links in dextrin molecules without increasing the amount of glucose produced. In examples, saccharification is effected with oxalic acid or α-amylase. The product contains glucose, a high proportion of biose (e.g. 57.2-69.7%), lesser amounts of (3-5)-ose and up to, e.g. 28% dextrin.

The stack of confectionery trays 6 positioned between walls 1, and resting on two horizontal ledges 4 are discharged one by one by gripper 9 operated by crank 15 and guided and controlled by guide 17, the guide being pivoted at 18 and oscillated at 27 by rod 25 pivoted at 26 and operated by cam 24. The lowermost tray is withdrawn by the gripper between the ledges 4. Operation.-Gripper 9 is provided with rubber 11 which engages in a cup of the lowermost tray and moves it outwards whilst gripper 12, carried by gripper 9, engages the tray on its outer edge, the gripper 12 being influenced at 22 by a rod 19 pivoted at 20 and operated by cam 21. The lowermost tray, being thus gripped between grippers 9 and 12, is withdrawn downwards and then released to slide down shoot 28 towards a packing machine.

Abstract: 1,233,045. Position resolvers. MARCONI CO. Ltd. Feb.26, 1969 [April 1, 1968], No. 15468/68. Headings G1A and G1N. In an electrical position resolver in which X, Y co-ordinates of position of a movable probe, 2, on a resistive sheet, 1, are represented by the respective magnitudes of first and second alternating voltages of differing frequencies, co-ordinate errors are corrected using photographic records of the errors. The respective A. C. signals from the probe are separated by filter circuits 7, 8, rectified by diodes 9, 10, and both fed to the deflection coils 17, 18, of respective C.R.T. flying spot scanners 13, 14, so that the instantaneous position of each spot in the area it scans corresponds to that of the probe on the resistive sheet. The light beams from the spots are fed through respective photographic plates 15, 16 on which are pre-recorded the co-ordinate errors so that on transmission through the plates the light beams are intensity modulated in accordance with the errors, thus respective photo-multipliers 19, 20 produce error-correcting voltages which are amplified at 21, 22 and fed to respective summing circuits 11, 12, to yield corrected co-ordinate signals at outputs 23, 24. The position co-ordinate errors are recorded on the photographic plates as follows. The probe is moved over the resistive sheet in a raster scan, which probe movement is synchronized with that of the sliders of two linear potentiometers (not shown) supplied from the two A.C. sources 5, 6, supplying the sheet so that the voltages at the sliders of respective potentiometers represent true X, Y co-ordinates. These slider voltages are rectified and compared with those from the rectifiers 9, 10 and the difference voltages are used to modulate the beam intensity of a respective flying spot scanner. The resultant error signal is recorded on a photographic plate.

Abstract: 1288214 Fluid-pressure servomotor systems GLENFIELD & KENNEDY Ltd 16 Sept 1969 [17 Sept 1968] 44101/68 Heading G3P In a fluid-pressure regulator having an inlet 5, and an outlet 6, control of the disposition of valve member 2 is achieved by varying the pressure of fluid acting on a pressure responsive member 3, with such variation being achieved by means of a pilot valve 8. In operation, upon the outlet pressure exceeding a desired value, a piston 12 of the pilot valve is caused by the outlet pressure acting on a diaphragm 9 secured thereto, to move against the force of a spring 10 and so to move valve member 11 in a direction tending to close a bypass duct 4. As a result, fluid-pressure build up within the duct acts on member 3 and so moves closure 2 towards its seat. Conversely, a lowering of pressure at the outlet 6 causes valve member 11 to move in a direction to open the by-pass duct with the result that more fluid escapes from the duct than can enter through the restriction 7. Hence upstream pressure acting on member 3 moves the latter in a direction such that valve member 2 moves in a valve opening direction to so increase flow from the inlet 5 to outlet 6. Piston 12 is arranged to move freely within its cylinder 14 and is so dimensioned that in the event of the diaphragm 9 fracturing the operation of the pilot valve is not adversely or substantially altered. The dimensioning of the piston is made such that its area is greater than the effective area of the diaphragm 9, the effective area being different from the actual area of the diaphragm due to the fact that the portion of the diaphragm adjacent to the gripped portion is less free to flex than the portion of the diaphragm nearer the centre. The effective area may be calculated by dividing the thrust produced by a given pressure acting on the diaphragm by that pressure. The valve may be modified to act in the manner of a pressure-sustaining valve which maintains a desired constant pressure at the upstream side 5 of the valve 1. In such a case, the pilot valve 8 is made responsive to the upstream side 5 and is disposed upstream of the restrictor 7.

Abstract: 1323872 Water-jet propulsion unit MINISTRY OF DEFENCE SECRETARY OF STATE FOR 12 Jan 1971 [23 Oct 1969] 52063/69 Heading B7V A marine propulsion unit, e.g. for hydrofoil and hovercraft, comprises an annular duct 1 attached to the hull of the craft by a hollow strut 2 down which air or other gas passes into a circumferential plenum 3 from whence it passes into the duct 1 through a group of holes 4 flush with the smooth inner surface of the duct 1. Within the duct 1 is a rotor 5 having a single row of blades 6 and carried on a streamlined central hub 7 which is supported from the duet by streamlined struts 8. The gas introduced into the water flowing within the duct 1 is distributed reasonably uniformly in small bubbles over the whole cross-section to produce a homogeneous two-phase flow which acts as a compressible fluid. The shape of the after portion of the duct is such as to cause this compressible fluid to expand thereby converting the pressure head within the duct into a velocity head at the duct exit. The channels formed between the blades 6 of the rotor 5 gradually deepen radially in the downstream direction to provide some or all of the extra volume occupied by the added gas. The gradual deepening may be due to the shape of the central hub 7 (Fig. 2, not shown) and this gradual deepening may be supplemented by a step in the duct surface upstream of the holes 4 (Fig. 3, not shown). In this latter arrangement, the water flow separates from the wall to produce a free water-gas interface which breaks up and thus induces rapid mixing of the gas and water. In either case, the distribution of the gas through the water is aided by the radial pressure gradient arising from the circumferential velocity compoment of the water.
