Title: Use of a rankine cycle apparatus on a vessel to convert energy from waste streams to mechanical energy
Inventor: ELSHOUT WILHELMUS HUBERTUS HENRICUS ANTONIUS VAN DEN
IPC: B63H21/20
Filed: 2009-07-14
Abstract: The invention relates to the use of a rankine cycle apparatus, which transfers heat of the relatively hot waste streams, like off-gas or hot cooling water, from a vessels primary power unit, into mechanical energy in a turbine and to exert its mechanical forces for powering of the propellers, or other propulsion means of the vessel. Preferably, the mechanical energy is directly transferred to the shaft of a propeller, optionally with aid of gear-box. Alternatively, the energy from the turbine is used to power a generator, which transfers the mechanical energy into electricity, which electricity is used to generate mechanical energy for propulsion of the vessel, or to power apparatus on a vessel. The vessel may be a high energy consumer, like a cruise ship or cooling vessel.

Title: Process for treating products such as films, sheets, and the like of regenerated cellulose
IPC: D06M11/155
Filed: 1931-04-07
Abstract: Films or sheets of regenerated cellulose are treated with the usual plasticizers in conjunction with small quantities of hygroscopic substances such as hygroscopic salts, the quantities employed being insufficient to retain the film in the hydrated condition or cause hydration thereof or interfere with the normal drying procedure. Suitable plasticizers are glycerine, grape sugar, glucose, or sulphite pitch.  The hygroscopic substance preferably has a greater affinity for water then glycerine, glucose, or other sugar commonly used as plasticizer.  In an example, a film of regenerated cellulose obtained from viscose, or cuprammonium cellulose solution, is passed through a solution containing 10-15 per cent of glucose and 0,25-0,5 per cent of magnesium chloride.  Calcium chloride may also be used as the hydroscopic substance.

Filed: 1942-07-23
Abstract: 556,292. High frequency electric heating. REDIFFUSION, Ltd., and ADORJAN, P. July 23, 1942, No. 10305. [Class 39 (iii)] In high frequency electric heating apparatus, e.g., for moulding plastics, industrial ovens, or therapeutical apparatus, employing a pair of spaced members 4, 5 between which material to be heated is located in a high frequency field, any variation in the distance between the members 4, 5 varies the electrical characteristics of the tuned circuit 7, 8, by varying the capacity between the members 4, 5. This is corrected and the tuning maintained by providing electrodes 12 movable with the member 4, associated with fixed electrodes 11, so that the total capacity remains unchanged by the movement. Other mechanical couplings between the plate 4 and the condenser may be employed, Figs. 2, 3 (not shown). In Fig. 4 a cam 25 on the plate 4 moves a rod 23 carrying the core 22 of a variable inductance.

Filed: 1975-03-13
Abstract: 1500442 Amplified telephone set SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 13 March 1975 [21 March 1974] 10449/75 Heading H4K Amplifying telephone set has a voltage regulating circuit RT which is connected to the incoming lines and supplies D.C. power to a microphone amplifier AM and a reference voltage r equal the mean value of the potentials on the lines ab. The microphone amplifier has a symmetrical high impedance output, of mean level equal the mean value of potential on the line ab. The receiver amplifier AR is supplied by the line, has a symmetrical high impedance input, and is connected to receive the reference voltage r from the regulator circuit so as to allow maximum voltage swing at the receive transducer R. A connection circuit FT interconnects the line, the microphone amplifier output, the receive amplifier input and the balancing impedance Z. As described the set uses a resistive antisidetone network FT of the type disclosed in Application 9836/75 to interconnect the transmitter M, receiver R, line ab and balance network Z. The microphone amplifier is biased so that the standing output current is half the maximum current allowing modulation from 0 to twice the standing current. The reference potential r, from the symmetrical regulator RT, applied to the receive amplifier maintains the differential amplifier A2 output potential at the mean potential of the lines ab.

Title: Improvements relating to the thermo-electric measurement of temperature
IPC: G01K7/02
Filed: 1920-04-15
Abstract: 164,916. Rowcliffe, F., and Cambridge & Paul Instrument Co., Ltd. April 15, 1920. Temperature errors, compensating for. - The temperature coefficient of a galvanometer or the like G used in a circuit including a thermoelectric couple E for measuring temperatures is compensated for by so selecting the ohmic values of fixed series and shunt resistances C, B, adapted for alternative connection in the circuit including the galvanometer and an adjustable series resistance A, that the temperature coefficient of the galvanometer and the remainder of the circuit is compensated by suitably setting the adjustable series resistance. The circuit includes two singlepole switches D, D' for changing over from the series to the shunt connections. Equations are given from which the ohmic values of the resistances C, B can be determined; these resistances are of manganim &c. having a negligible temperature coefficient. The resistance A is adjusted until the deflexion of the galvanometer is the same whether the switches D, D<1> are both open or both closed.
Patent GB-559948-A (GB)
Title: Improvements in the manufacture of intaglio printing plates and cylinders
IPC: B41N3/00
Filed: 1942-07-28
Abstract: 559,948. Intaglio printing-surfaces. LABWORTH, D. July 28, 1942, No. 10549. [Class 98 (ii)] [Also in Group XVI] In the preparation of an intaglio plate or cylinder, the surface is etched with a photogravure screen, the design is applied photographically, 'by drawing, or by transfer so as to leave the non-design areas bare, the tops of the screen-cell walls in the non-design areas are coated with ink, the cells in these areas are filled up by electroplating, and the ink and designforming materials are cleaned off. The plating can be removed when the plate or cylinder is required to be used again in the preparation of a different printing-surface. In an example, the plate or cylinder is of steel or copper, and after etching, the screen is plated, if of copper, with chromium or other hard metal. A light sensitive glue coating is applied, exposed under a dot-tone or line negative, and developed to remove the unexposed parts. The surface is then rolled up with ink to coat the tops of the cell walls on the bared metal, and in the case of a plate, the back is also coated with ink or other protective medium; whereafter the plate or cylinder is copper plated to fill the screen cells ofthe surface where there is no glue or ink, and cleaned as with petrol. It then has a printing-surface filled with copper to the top of the cells where " whites " 'are required, the parts not so filled serving to print "blacks." Corrections can be made by etching out unwanted " whites," or filling in unwanted " blacks " as by electroplating or using copper amalgam, glues, &c. In order to render the plate or cylinder available for further use after completion of the run, the copper plating may be removed either by etching with iron perchloride or acid, or by making the plate or cylinder the anode of a plating bath. In alternative processes, (1) if the sensitive layer is an admixture of glue and gelatin, a continuous tone negative may be used ; (2) instead of a sensitive glue coating a carbon tissue consisting of pigmented glue and gelatin may be used; and (3) the design may be applied to the surface non- photographically, e.g. by drawing it with a litho crayon, or applying it by transfer.
