Title: Pneumatic detector for chromatographic analyser
IPC: F15B5/00
Filed: 1976-01-28
Abstract: 1495693 Gas chromatography FOXBORO CO 28 Jan 1976 [14 Feb 1975] 03272/76 Heading G1S [Also in Divison B1] A device for use with a gas chromatograph incorporating a separation column and in which a sample mixture is injected into the column and conducted through by a carrier gas. The components of the mixture emerging from the column at different times, has means to determine the concentration density of each component, the reading being connected for the influence of flow velocity by a capillary element producing a signal responding to the viscosity of the component. A carrier gas is fed to an injection valve 12 to which the sample is also fed. Sample components leave the column 14 to enter a manifold 20 having a passage 24 communicating at one end with a bellows 40 and at the other with a restricting orifice 26. Pressure in the bellows 40 is that obtaining upstream of the orifice. Downstream is sited a capillary tube 60 and a bellows 44 is connected by a lead 34 to the space upstream of the capillary, the bellows 44 opposing the bellows 40 against a force bar 42. The area of the bellows 44 is greater e.g. twice, than the area of the bellows 40 and as pressure within it is negative, both bellows tend to pivot the bar towards a nozzle 46 supplied with pressure air via a Venturi 48. A lead 18 connects the Venturi to means receiving the measurement signal and to a bellows 50 opposing the pivoting of the beam. A spring 66 enables application of an adjustable biasing force and the gain of the beam system may be varied by moving the fulcrum 52. The capillary may include a restricting wire 72, the length of which determines the length of the tube acting as a capillary. In an alternative arrangement Fig. 4 (not shown) the bar 42 is pivoted at one end and the spring 66 operates from below.

Title: Improvements in or relating to electric water boilers
IPC: A47J31/54
Filed: 1962-01-30
Abstract: 938,195. Electric water heaters. O. EBERLE, and H. KOHLER, [trading as EBERLE & KOHLER KOMM. - GES.]. Jan. 30, 1962 [March 14, 1961], No. 3426/62. Class 39 (3). An electric water boiler includes a water chamber communicating with a smaller, auxiliary chamber by a restricted opening, a heating element for heating the water in the water chamber and auxiliary chamber, and a device for sensing the temperature of a wall bordering the auxiliary chamber, whereby to interrupt the current supply when the sensed temperature rises a predetermined amount above boiling point due to the expulsion of the water from the auxiliary chamber by the bubbles developed when the water boils. Temperature sensitive switch 2, Fig. 1, interrupts the current supply to heater 4 when the temperature in the auxiliary chamber rises to e.g. 110‹ C. as a consequence of the water boiling. Small opening 5a, and slot 5b, permit the expulsion of the water, and avoid the trapping of air when filling the container. The heater 4 may be mounted in the water chamber itself, Fig. 3, and extend into the auxiliary chamber formed by the removable member 5, in which a thermally conductive member 6 enhances the conduction to the switch 2.

Patent GB-601212-A (GB)
Title: Improvements relating to the separation of wax from crude wax fractions obtained from petroleum distillates
IPC: C10G73/36
Filed: 1944-06-25
Abstract: <PICT:0601212/III/1> <PICT:0601212/III/2> Wax is separated from crude wax fractions obtained from petroleum distillates by causing the crude wax fraction at a temperature at which it consists of a liquid fraction and a fraction in a semi-solid and flowable condition to flow continuously through a separating apparatus and separately discharging the liquid and semi-solid fractions from the apparatus. In Fig. 1, a liquid oil-wax mixture is fed from tank 10 by means of pump 11 past flowmeter 14 to a cooler 12, in which the mixture is cooled to a temperature at which it consists of a liquid fraction and a fraction in a semi-solid and flowable condition, about 5 DEG  F. below the temperature at which wax first separates being suggested. Compressed air is introduced into the cooler through valve 25 above the liquid level 27 and scraper blades such as 16, rotating on a shaft 22, entrain air in the mixture.  The mixture then passes through pipe 28 into the separating vessel 13, where the semi-solid fraction, rendered buoyant by the entrained air, rises to the open top and runs, with the assistance of travelling scoop 35, into receiver 34.  The liquid fraction is drawn off through valve 32, perhaps after passage through a filter medium. Alternatively the compressed air may be dispensed with and the cooler 12 filled completely with liquid.  In this case a separating vessel as shown in Fig. 3 is used, the semi-solid fraction falling by gravity to the outlet 42 and the liquid fraction being withdrawn through pipe 44. Either fraction obtained by the process may be re-circulated, while the semi-solid fraction may be cooled and sweated.  Apparatus for carrying out this sweating step is shown, either combined with or distinct from the separating vessel already referred to.

Title: Improvements in or relating to photographic cameras combined with light sources
IPC: G03B15/04
Filed: 1939-02-03
Abstract: 523,129. Photographic cameras combined with flash lamps. KODAK, Ltd. Feb. 3, 1939, No. 3628. Convention date, Feb. 5, 1938. [Class 98 (i)] In a camera combined with a light source substantially in the plane of the objective, the amount of light falling on the focal plane is kept constant for a given shutter setting and any correctly-focused position of the objective by a coupling which connects the diaphragmadjusting means and the objective focusing means, and is adjustable to compensate for film speed and intensity of the light source. As shown, the camera 4 is secured at 7 to a carrier 1 on which are adjustably mounted one or more pivoted arms 2 carrying lamps and reflectors. The electric circuit of the lamps include a switch 6, coupled to the shutter release mechanism, whereby a resistance may be included in the circuit during the focusing operation, and cut out when making an exposure. The objective focusing ring and the diaphragm adjusting ring are coupled respectively by links 9, 14 to the ends of a lever 10 pivoted at its middle 12 on the carrier 1 and operable by a knob 16 carrying a pointer 17 moving over a distance scale 18. The two arms of the lever 10 are relatively adjustable to allow for either the film speed or the number of lamps used, and in the latter case the lever 14 may be coupled to an intermediate ring 19 in frictional engagement with the diaphragm adjusting ring so that the film speed may be allowed for by relative angular adjustment of these rings.

Title: Improvements in and relating to tuned circuits
IPC: H03B5/18
Filed: 1967-01-25
Abstract: 1,210,511. Tuned circuits. MULLARD Ltd. 24 April, 1968 [25 Jan., 1967], No. 3682/67. Headings H3Q and H3T. A high-frequency tuning circuit comprises a varicap diode connected between one end of a half wavelength line and a reference voltage, and is tuned by variation of the bias voltage applied across the diode. Such a tuned circuit is described as part of the amplifying and selfoscillating mixing stages of a television tuner. In Fig. 11 there are three such tuning circuits, two of which, L9, C11 and L7, C12 are associated with the signal frequency band-pass filter and the other, L8, C13, with the oscillator stage. All of these tuning circuits incorporate line inductive trimming loops L22, L10, L11. A further varicap diode C21 is used in the rejector circuit of the aerial input, to tune the rejector inductors L15, L16. In Fig. 10 a line L1 is connected to a varicap diode C1 and also to the wall of the trough T through capacitor C2. The line is extended by an inductor L2 connected through an isolating capacitor C5 to the collector of transistor TR1. Inductive feedback is applied to the emitter of TR1 by inductive loop L4 and capacitive feedback from capacitor C2 via capacitor C6 to the emitter electrode. Fig. 8 (not shown) uses a common potentiometer to bias all three varicap diodes of a multiple tuning circuit arrangement, with individual trimming potentiometers used to counteract any diode characteristic differences. In Fig. 12 (not shown) adequate image frequency rejection over the whole of the U.H.F. band is ensured by incorporating a further R.F. amplifier and tuned circuit into the circuit of Fig. 11.
