Title: Improvements in and relating to anti-rolling apparatus for ships
IPC: B63B39/06
Filed: 1936-05-21
Abstract: 471,220. Stabilizing ships. BROWN BROS. & CO., Ltd., WALLACE, W., and DENNY & BROS., Ltd., W. May 21, 1936, No. 14355. [Classes 113 (i) and 113 (ii)] An installation for minimizing the rolling of ships includes as operative elements lateral fins which are designed to be protruded outwards and then oscillated about a thwartship axis to exercise an anti-rolling couple on the ship and to be retracted into the housings when not required. The fins 1, 1a are carried by hollow shafts 4 which are splined on shafts 5 and work in cylinders 6. The fins are extended and retracted from a hand lever 26 associated with a valve chest 23 through which pressure fluid is supplied from a servo-pump 13 to the cylinders 6. The oscillation of the fins is effected from a gyroscope 3 which through solenoids 19, 20 controls the valve 18 which regulates the supply of pressure fluid from the pump 13 to the servo-control motor 17. The position of a three-armed lever 16 is thereby adjusted and through the links 31, 32 operates the delivery-regulating levers 14 of the pump 11 to supply fluid to the appropriate cylinder 8 of rams 9. Tiller arms 10 connect the rams 9 with the shafts 5 on which the fin-carrying shafts 4 are splined. The cylinders are connected by a linkage 15 with the three-armed lever 16 and constitute part of a hunting-gear which brings levers 14 back to mid-position when the fins attain the requisite angular settings. The permissable angle of oscillation of the fins is regulated by stops on the controlmotor 17, and the speed of operation of this motor is controlled by the adjustment of obturator valves in the supply ducts. A device is provided to ensure that the fin protruding gear can only be operated when the fins are in mid-angular position.

Title: Improvements in or relating to current-responsive electric switches
IPC: H01H71/40
Filed: 1956-08-20
Abstract: 843,484. Magnetic switches. FALK STADELMANN & CO. Ltd. Aug. 20, 1956 [May 18, 1955], No. 14375/55. Class 38 (5). An overload cut-out comprises a W-shaped bimetal blade 2 secured at the ends of its outer limbs to a support 1 by screws 4, the end of the centre limb 7 carrying a contact 8 normally engaging a fixed contact 9. A ferromagnetic block 11 is disposed beneath the blade 2 whereby at a certain value of current, which enters at the ends of the outer limbs and leaves through the contact 8, the heating effect of the current through the blade flexes it towards the block 11; also, the pair of magnetic poles produced by the current flowing from the outer limbs into the centre limb causes attraction of the blade to the block whereupon the centre limb 7 engages a fulcrum 12 and the contacts 8, 9 are rapidly separated. As shown, there are two similarly-acting blades 2, 3 connected in series, the centre limb of the lower blade 3 co-operating with a fulcrum 13 and engaging a fixed contact 10. The outer limbs of each blade are connected by a narrow strip 2<SP>1</SP>, the centre limb 7 terminating at 7<SP>1</SP>. The thermal heating effect may be augmented by a resistance element situated around or adjacent the blades and connected in circuit therewith. Latches 14 maintain the blades in the open circuit condition. In a modification (Figs. 4-6, not shown), the magnetic effect of the block 11 is increased by forming it with a pair of cores in axial alignment with the poles produced by the current in the blades, and providing the cores with windings in circuit with the blades.

Abstract: 295,779. Marks, E. C. R., (Pacific Northwest Paper Mills, Inc.). May 30, 1927. Printing-apparatus. - In an apparatus for printing label or other designs in a number of different tints on a web of paper or other material, the web is passed through a dye bath, then between a pair of rollers adapted to apply different degrees of pressure to different parts of the web, and again through the dye. The rollers comprise an impression roller 9, Fig. 6, and a printing-roller 10 having a number of recesses 15, Figs. 1 and 2, in which are secured plates 23 bearing designs in intaglio. Liners 22 are placed under the plates to cause their outer surfaces to project slightly beyond the periphery of the roller, and the plates are clamped by spring eyes 21 engaging cross pins 26 which extend across slots 24 in the plates. The web 33 passes round a guide-roller 34 immersed in a dye bath 35, and thence between the rollers 9, 10, round a second immersed guide-roller 34, and finally between a pair of wringing-rollers 27, 28. The parts of the web which are opposed to the intaglio diesigns and to the margins of the recesses 15 are not subjected to pressure and the colour imparted to the web by the dye remains unchanged. Those portions of the web subjected to the pressure of the plates 23 are caused to assume a darker tint. while those subjected to the lighter pressure of the body of the roller 10 receive an intermediate tint. Specification 295,778 is referred to.

Abstract: 852,861. Earth-moving equipment. ALLIS-CHALMERS MANUFACTURING CO. April 28, 1959 [April 29, 1958], No. 14538/59. Class 68(1). The pivot arms 36 of the front apron 35 of a bowl-type, earth-moving scraper are so shaped, guided and connected by linkage to the ejector plate 20 of the scraper that when the ejector is advanced through the bowl of the scraper the apron is simultaneously moved forwards whilst being pivoted upwards. At the elbow of the cranked ends 40 of the apron arms are rollers 38 which move in the same guideways 24 on the sides of the scraper bowl as the guide and supporting rollers 22 of the ejector plate. Links 39 are pivotally connected between the cranked ends 40 of the apron arms and brackets on the ejector plate, which is advanced by jacks. Movement controlling links 44 extend between the apron and the front of the bowl structure. Initial opening movement of the apron is due to jack 48 acting on a cable 50 fixed to the yoke of the scraper bowl. The jacks 48, 27 are simultaneously supplied from the same fluid source, the jacks 27 only becoming effective when the apron has been raised sufficiently to break the two toggle linkages formed by the links 44, 39. The weight of the apron returns the ejector plate when fluid pressure in the jacks 48, 27 is reduced.

Filed: 1919-06-10
Abstract: 149,813. Chapman, E. B. June 10, 1919. Motor power plant; driving and tranmission mechanism; heating parts .-The auxiliaries of a motor-power plant are driven by the main prime-mover until, owing to reversal, reduction in speed, &c., it is no longer capable of doing so, whereupon the drive is automatically taken over 'by an auxiliary prime-mover. For example, the main steam-turbine 1 normally drives, through gearing 10 and a free-wheel device 11, the rotary pump 6 for supplying oil to the turbine gearing 3; but the drive is taken over by an auxiliary turbine 9 when the pressure in the steam inlet belt of the turbine falls below a certain limit, this belt being connected by a pipe 15 with a piston 18, Fig. 3, controlling the inlet valve 16 of the turbine 9. The turbine 9 is kept warm while idle by leakage steam flowing through a hole 20. The positions of the units 6, 9 may be interchanged, an additional free-wheel device being arranged between the turbine 9 and the pump 6. A suitable free-wheel device is shown in Fig. 5, the inner member carrying sliding plungers 25. Friction clutches may be used instead of free-wheels. The invention is also applicable to electro-motors and reciprocating engines.

Title: Information and process control enhancement system
IPC: G06F17/14
Filed: 1975-04-10
Abstract: 1515122 Signal enhancement systems BATTELLE MEMORIAL INSTITUTE 10 April 1975 [19 April 1974] 14867/75 Heading G4A An input signal S(t) N(t), Fig. 2, including a noise factor N(t), is enhanced by digitizing the input signal in an A/D converter 10 whose output is transformed into a series expansion of Walsh functions in a converter 14; a given estimate #(t), of the noise factor also being digitized in an A/D converter 16 and being transformed first into a series expansion of Walsh functions in a converter 18 and then into the reciprocal of the series expansion from converter 18, which is also a series expansion of Walsh functions, by a reciprocal converter 20; the output of converter 14 being multiplied by the output of converter 20 in a multiplier 22 which effectively divides out the noise factor, the series expansion of Walsh functions from multiplier 22 then being transformed to digital form in an inverse convecter 24 whose output feeds a D/A converter 26 which in turn provides the enhanced input signal. In another embodiment, Fig. 3 (not shown), an estimate (S(t)) of the input signal is given instead of N(t), the circuit including an extra reciprocal converter (20<SP>1</SP>) for generating the reciprocal of the Walsh transform of S(t), and an extra multiplier (32). In Fig. 4 (not shown) a feedback control system is illustrated for controlling the speed of an electric motor (36), a reference speed signal from a driving oscillator (12) being Walsh transformed (38, 40) and multiplied (50) by the reciprocal Walsh transform of an actual speed signal obtained (42, 44, 46, 48) from the motor (36). In the case of synchronism between the two speed signals the output of multiplier (50) is unity, any discrepancy in the motor speed resulting in a correction signal being generated (52, 54) from the output of the multiplier (50) and sent to the field winding (56) of the motor. The Walsh function converters, e.g. 14, are shown in Fig. 6 for the case of a four-component digitized input signal, the components being stored in portions 1-4 of a register bank 34. A control unit 36 causes adders 37, 39, 41, 43 to prooduce from the outputs of the register bank 34 four outputs α 0 -α 3  which represent the coefficients of the Walsh function series, α 0 -α 3  being given by four combinations of the portions 1  2  3  4. A circuit for implementing the multipliers, e.g. 22, is given in Fig. 9 (not shown), and a circuit for implementing the inverse converters, e.g. 24, which is generally similar to Fig. 6, is illustrated in Fig. 8 (not shown). In Fig. 10 (not shown) a circuit is illustrated for the reciprocal converters, e.g. 20, which includes a computing circuit for solving a set of linear simultaneous equations in four unknowns for the coefficients of the reciprocal Walsh series in terms of the coefficients of the original Walsh series.

Abstract: 475,877. Exhaust and like silencers. BLANCHARD, J. G. May 26, 1936, No. 14888. [Class 7 (ii)] A silencer for pulsating gaseous currents comprises an inner path for the gases constituted by a tube 8, and an outer path by the space between the tube and an outer casing 1, the tube being perforated at 24 for the passage of some of the gases into the outer path by way of chambers 25 formed within corrugated or star-shaped members 17 and closed at one end 19. A through-passage is thus formed along the outer path by the depressions 23 between the chambers 25. The tube may be divided into units by diaphragms 14 apertured at 15 to provide a straight-through passage for the gases. The diaphragms 14 may be formed with tubular extensions 21, and an additional tube 22 may be attached to the last diaphragm. Injector cones 7, 9 provided at the inlet end cause a suction effect through apertures 11 upon the annular space 26, the volume of which may equal that of one of the cylinders of the engine. The cross-section of the straight-through path may be reduced in succeeding units, the perforations to the outer path being correspondingly increased. Again, the number of perforations 24 in successive units may decrease, and the outer path be correspondingly widened towards the outlet end. A valve may be provided in one of the tubes 21, 22 for intercepting the straight-through path.
