Title: Method and apparatus for measuring the n-nitroso compound content of a sample
IPC: G01N31/00
Filed: 1976-03-16
Abstract: 1512121 N-nitroso compound determination THERMO ELECTRON CORP 16 March 1976 [17 Sept 1975] 10520/76 Heading G1B A method of measuring in a sample the amount of N-nitroso compounds having the general Formula: - where R 1  and R 2  are the same or different organic radicals including those radicals which together with the non-nitroso N of the N-NO bond constitute a nitrogen heterocyclic radical and where the N-NO bond is the weakest in the molecules comprises non-catalytically pyrolyzing the sample at 300-500 C to provide sufficient thermal energy to break the N-NO bond but not break other bonds, and measuring in the gaseous phase the amount of nitric oxide liberated by the pyrolysis. In the case wherein the sample contains nitrate and/or nitrite compounds, the sample is first passed through a chromatograph column to separate the N-nitroso compounds from nitrate and/or nitrite compounds in the sample and then passing the sample to pyrolysis. The sample and a carrier gas may be passed through a gas chromatograph column. Alternatively the sample may be dissolved in a liquid solvent and passed through a liquid chromatograph column. Pyrolysis may be carried out in a uniform diameter, chemically inert tube which is maintained at the appropriate temperature.

Abstract: 454,597. Centrifugal machines ; treatment of sewage. AMERICAN CENTRIFUGAL CORPORATION, 70, Pine Street, New York, U.S.A. April 5, 1935, No. 10627. Convention date, April 12, 1934. [Class 23] [See also Group I] A centrifugal machine for the treatment of sewage has a basket mounted in a casing, the lower part of which forms an effluent treating and sedimentation tank; it receives the effluent discharged from the basket, and separate means are provided to remove the clarified effluent and the sedimentation sludge from the tank. The basket 13 is secured to the vertical shaft 44 and is driven through clutches 66, 67, Fig. 3, and bevel gearing, by high and low speed motors 68, 69. The bottom section 1 of the basket casing is cast with the base which is of irregular octagon form and comprises the tank 8 with four hollow columns with inner and outer walls 9, 10 rising from it. These columns communicate with the trough formed in the bottom of the basket casing by the flanged annular wall 20. The basket 13 has an imperforate wall and the bottom plate has a number of openings 34 for the discharge of sludge to the interior of the base structure. The annular top plate 32 of the basket has radial channels 36 covered by a seepage plate 37, and liquid from the basket passes outwards through the channels into the casing 3 from which it passes to the sedimentation tank. Chemicals for the treatment of the effluent may be introduced to the tank from the hopper 25, and steam or air may be introduced through the pipe 25b. The material is supplied to the basket through the feed pipe 72 which has two branches extending into the basket. The flow is controlled by a valve 73 operated by a hand wheel through worm gear, or the valve may be operated periodically by electric means. The sludge deposited in the basket 13 is dislodged by scrapers attached to the vertical shafts 83 and drops through the openings 34. The upper ends of the shafts 83 have operating arms 107 connected by a pin- and-slot mechanism to a sliding bar 111 operated through bevel and worm gear by an electric motor 118. The clarified or lighter effluent is drawn from the tank 8 through a standpipe 136, Fig. 6, by a suction pump 130, Fig. 3, which is driven through the clutch 131 and bevel gearing by the motor driving the basket. The heavy liquid or sedimentation sludge is removed from the bottom of the tank 8 through pipes 146, Fig. 3, and a suction pump 141 driven through a clutch 142. The upper and lower parts of the tank 8 are separated by a partition 8a with apertures 9<a>, and this partition may be inclined instead of being horizontal. Specifications 453,651, 453,652, and 453,653 are referred to.

Title: Circuit arrangements for generating impulses of rectangular waveform
IPC: H03K5/00
Filed: 1960-03-25
Abstract: 899,502. Transistor pulse circuits. FERNSEH G.m.b.H. March 25, 1960 [March 26, 1959], No. 10651/60. Class 40(6). In a pulse shortening circuit, the input pulse is applied through a capacitor to the base of a normally conducting transistor arranged in common emitter configuration so as to cut off the collector current, the current being restored before the end of the input pulse as a result of the charge or discharge of the capacitor through a base resistor. In the Figure, the application of a pulse to terminal 11 causes a cross-coupled monostable circuit 1, 2 to produce an output pulse C at the collector of 1. This is applied directly to an output terminal O and also through a shaping network 12, 13, 15 to a transistor 14. The effect of the resulting input waveform D and a wave H generated in the emitter circuit is to produce a delayed output pulse G, the amount of delay depending upon the setting of resistor 13. The pulse G cuts off transistors 20 and 26 which become conducting again before the end of pulse G when the respective capacitors 19 and 27 have charged sufficiently. Accordingly positive going pulses E and F are produced at the corresponding collector electrodes pulse E being longer than pulse F because the time constant of the capacitors (27, 28) is shorter than that of circuit 19, 21, and both pulses are delayed with respect to input pulse A because of the delay produced by the circuit of transistor 14.

Title: Continuous fermentation process and apparatus for beer production
IPC: C12C11/00
Filed: 1960-03-28
Abstract: 926,847. Continuous beer fermentation. R. RAMSDEN & SON Ltd., and R. P. WILLIAMS. March 28, 1961 [March 28, 1960], No. 10855/60. Class 14 (2). A continuous process for the fermentation of wort and yeast in the production of beer includes a first step of continuously forming a mixture of sterile wort and yeast in a first vessel under temperature conditions ensuring multiplication of the yeast, and permitting the mixture to dwell in the first vessel for a period of time ensuring production of a yeast culture and onset of fermentation of the wort, a second step of continuously removing wort and suspended yeast mixture, passing the removed mixture into a second vessel and permitting the mixture to dwell in the second vessel for that longer period of time required to ensure completion of fermentation of the wort at the concentration of yeast as derived from the first step, and a third step of continuously removing fully-fermented wort (beer) and passing it into a third vessel for cooling and settling. In the embodiment of apparatus depicted in Fig. 1, for top fermentation, yeast is propagated in a wort and yeast mixture formed in a first vessel 1, wort and suspended yeast are transferred to and held in a second vessel, constituted in the embodiment by two serially connected vessels 2, 3, for sufficient time to ensure completion of fermentation of the wort, and fully fermented wort is allowed to cool and to settle in a vessel 4. The series of vessels is arranged successively at lower levels whereby the flow of liquid through the apparatus is obtained by gravity. Each vessel has independent jackets for heating or cooling at separate levels, suitable temperatures being disclosed. Gas inlets 21a, 27a, are provided at an intermediate point up vessels 1 and 2, respectively, for introduction of pressurized carbon dioxide to boost the fermentation; carbon dioxide produced during the rapid fermentation in vessel 2 is drawn off through a conduit 25 at the top of the vessel. Nitrogen for slowing down the fermentation may be admitted through conduits 21 and 27, at the base of vessels 1 and 2, respectively. Carbon dioxide for gasifying the fermented wort in vessel 4 may be introduced through a conduit 40. The yeast head 30 formed at the top of vessel 3 is continuously removed by suction to a filter 34 and the small amount of wort recovered by the filtration is returned to the flow path, e.g. immediately after vessel 3. A baffle device for entraining the yeast head, of the form shown in Fig. 3, may be applied to the outlet of vessel 3. Fig. 2 (not shown), depicts an arrangement suitable for bottom fermentation, but is in other respects similar to that shown in Fig. 1.

Abstract: 358,461. Fluid - pressure brakes. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. April 5, 1930, No. 10874. Convention date, April 8, 1929. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] In differential pressure or vacuum-operated servo mechanism in which a piston within a cylinder a applies the brakes, the pressure within the cylinder is controlled by a valve actuated by a member movably connected with the driver's operating lever, the valve k, m being suspended by one or more leaf springs or, as shown, by one or more flexible diaphragms n in order to reduce resistance to movement. The diaphragm n, perforated for equalization of pressure, and slotted or recessed so that its tensioned centre can be displaced axially of the valve, is secured along its circumference to the casing c and is clamped at its centre between the two parts k, m of the valve. Rubber discs o, p cover alternately, when working, channels d, e in the casing c which lead respectively to the induction pipe of the engine and to the atmosphere, the casing c being connected with the cylinder a by a channel b. The valve is operated by an electromagnet f having its winding connected through leads h, i to a circuit including a switch on the brake-operating lever. The end of the stem of the valve is supported by a sliding bearing s or by a diaphragm. If the braking pressure is to be kept at a constant value, the valve is displaced rapidly from one end position to the other. It is stated that the invention can be applied to other types of servo-mechanism, for instance, those having manually-operated valves.

Title: Improvements relating to car retarder control apparatus
IPC: B60K31/00
Filed: 1953-04-21
Abstract: 724,845. Railway track brakes. WESTINGHOUSE AIR BRAKE CO. April 21, 1953 [April 23, 1952], No. 10886/53. Class 103 (1). The invention comprises further development of the retarder control apparatus, particularly for railway shunting yards, of the type described in Specifications 576,132 and 724,844. The application of the brake bars to the wheels of vehicles passing through the car retarder CR is by means of a fluid pressure actuator cylinder 200 controlled by solenoids R and X and pressure switches 1P, 2P and 3P by which the pressure may be regulated from the full value of 100 lbs. per square inch to partial pressures of between 25 and 35, 50 and 60, and 75 and 85 lbs. per square inch respectively as described in the above Specifications. As in the prior arrangements one rail 1b of the retarder is divided into a number of insulated sections 1S to 11S and a wheel passing each track section operates a track relay of the series 1T to 11T which are used to control timing mechanism comprising an AC cycle repeater CP, a multiple cycle counter MC, a unit cycle counter UC and control panels PFS and IP. As in Specification 724,844, a series of push buttons 1PB to 6PB are provided whereby the operator may select speeds such as 4, 5, 6 ... 9 miles per hour at which it is desired that a car shall leave the retarder. The push buttons 1PB to 6PB operate respectively relays 1PR to 6PR. The relays 1PR to 6PR control a series of front and back contacts 31 to 36 and 37 to 42 which are linked by lines in cables C1 and C2 to terminal sockets 1A to 6A and 1B to 6B. By means of plug connectors such as Y1 and B1, the sockets 1A to 6A and 1B to 6B may be connected to any desired socket in the series XPA to 4PA from which leads 52 to 56 extend to circuits controlling the pressure responsive switches IP, 2P, 3P so that the full or any of the pressure ranges may be applied to the brake bar operating cylinder 200 for any particular leaving speed as selected by the PB button. The control panel PFS is somewhat similar to the panel 1P and comprises a series of plug sockets UA, MA and MB, which may be connected as necessary by connectors such as R1, BB1, G1 and Rll, to produce different partial pressures and full release speeds for each of the different leaving speeds of the push buttons. The sockets' 1 MA to 6MA and 1MB to 6MB in the panel PFS are linked by lines through cables C6 and C7 to the relays 1M to 6M of the multiple cycle counter MC. The front contacts 92 to 102 are connected in multiple to wire 103 and thence through the resistors 104 to 109 and wire 110 to relay IPPR. Similarly contacts 118 to 128 are connected in multiple to line 129 which by way of resistors 130 to 135 is connected to relay 2PPR. The connections between the pushbutton relays 1PR to 6PR and the panel IP and between the panel PFS and multiple cycle counter MC thus combine to provide through relay 2PPR, line 141, terminals XPA and line 52, the control of the fluid pressure actuation necessary to produce the required car speeds on leaving the retarder.
