Title: Improvements in and relating to a method and means for measuring the amount of gas dissolved in a liquid
IPC: G01N33/18
Filed: 1926-01-22
Abstract: 259,086. Daynes, H. A., and Cambridge Instrument Co., Ltd. Jan. 22, 1926. Testing and estimating.-The amount of gas held in solution by a liquid is measured by comparing the properties of another gas before and after scrubbing by the gas-bearing liquid. An apparatus is shown for measuring the amount of oxygen dissolved in water, for example feedwater for steam boilers. The water to be tested flows through a pipe 1 to a constant-head device 2 furnished with an overflow 3 which by-passes excess water to waste. Water flows at a constant rate through the pipe 4 and is distributed over a large number of small pieces of nickel in a scrubbing device 5, passing thence through a water seal 6 to waste. Pure hydrogen, generated at the electrode 11 of an electrolytic cell 10, passes through a pipe 13 and divides, one part passing by a pipe 14 to a comparing-device or catharometer 21 and the other part passing by the pipe 15 to the lower gas space 17 of the scrubber, through which it rises in counterflow to the water to be tested and passes by the pipe 18 to the other chamber of the catharometer 21, finally escaping to atmosphere through the pipe 22. The catharometer 21 depends for its operation on the difference of heat conductivity of two different gases, and is described in Specification 124,453. In operation a measured continuous counterflow of pure hydrogen is passed through the scrubber, sweeping out the dissolved oxygen from the water. The combined gases pass to one chamber of the catharometer 21, which indicates the percentage of oxygen therein. The percentage of oxygen originally present in the water under test may therefore be calculated.

Title: Improvements in and relating to attenuating circuit arrangements
IPC: H03G3/32
Filed: 1964-01-17
Abstract: 998,437. Automatic volume control circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 17, 1964, No. 2181/64. Heading H4R. In an automatic volume control circuit an alternating control voltage is rectified and controls the attenuation of a bridge circuit of voltage dependent impedances in the input circuit of an amplifier, the output of the amplifier being positively fed back to a balance point associated with the bridge circuit. Fig. 1 shows the preferred form of the invention in which signals applied to terminals 2 pass via a variable attenuating bridge circuit 3 to the input of an amplifier 1. The attenuation of the bridge circuit 3 is controlled in accordance with the level of an alternating control voltage from a source 5, which may be a microphone responsive to the ambient noise level in order that the level from the amplifier 1 may increase as the ambient noise level increases and vice versa. The alternating control voltage from source 5 is amplified in amplifier 4 and transistors 6 and 7 then rectified by diodes 8 and 9 and the resulting D.C. potential is applied to control the impedance of the rectifier bridge 3. In order that the bridge circuit 3 is virtually floating with respect to earth positive feed-back is applied from the output to a tapping on resistor 14, a point balanced with respect to the D.C. control voltage. The feed-back results in a signal appearing on points 29 and 30 virtually equivalent to the input voltage on terminals 2 and thus minimizes the effect of non-linearity of circuit 3 on the signal fed to amplifier 1. Diodes 24 and 25 are provided in the control signal path to give an amplitude characteristic which compensates for the non-linear characteristic of the rectifier bridge 3.

Title: Improvements in or relating to synthetic resinous products and methods of producing same
IPC: C08G16/02
Filed: 1948-01-26
Abstract: Resinous products suitable for use in moulding powders, castings, laminate, brake and clutch-linings, sand paper, fillers for hard rubber, grinding wheels, paints, electrical insulation and glues, are formed by reacting a mixture of furfuryl alcohol and formaldehyde under acid conditions.  Catalysts specified are lactic, formic, acetic, sulphuric, hydrochloric phosphoric and chloracetic acids; dimethyl sulphate and sodium acid phosphate, a pH of 1.5 to 3.5 being preferred.  The products may be mixed or copolymerized with vinyl acetate and/or chloride, lignin resins, and alcohol-soluble phenol-formaldehyde resins.  There are specified as fillers: asbestos, wood flour, slate dust, sand, carborundum and iron oxide; as solvents: methyl and ethyl alcohols, furfuraldehyde, and water. While fusible the resins can be admixed with proteins, e.g. casein, gelatine, glue or blood albumen, or melted into Buna or polychlorisoprene rubbers or natural or reclaimed rubber, to increase their oil resistance. For storage the acid products are preferably made alkaline after the reaction.  Temperatures above 100 DEG  C. may be used by doing the reaction in an autoclave, or temperatures below 100 DEG  C. can be used.  To obtain an aqueous solution of resin the reaction must be stopped before condensation is advanced too far.  In examples the furfuryl alcohol and formaldehyde are refluxed until separation of water begins, and the mixture is then dehydrated, or by stopping the reaction earlier, the resin is obtained in a hydrophilic state.  An example (13) describes a reaction under anhydrous conditions of furfuryl alcohol, paraformaldehyde and lactic acid, all of which have been dehydrated.

Abstract: 1,177,902. Digital comparators. SINGERGENERAL PRECISION Inc. 16 Jan., 1968 [19 May, 1967], No. 2295/68. Heading G4H. A comparator for indicating coincidence between a movable binary coded member 10 and a binary input command signal and for producing output signals indicating the required direction of movement of the member 10, in which the movable member has a plurality of commutator tracks, each track having a binary coded switching track and two feed tracks coupled to alternate segments of the binary coded track, includes a first circuit for applying the binary command signals and their inverses to first and second feed tracks respectively and second circuit connected to the binary coded tracks and to the feed tracks, the output from which determines the direction of movement of the member 10. In the embodiment described the most significant bit 78 of the command signal is fed to brush 70 and via an inverter 80 to brush 74 so that if there is not coincidence between the bit sensed by brush 72 and this bit of the command signal one of two AND gates 84, 86 in the second circuit are enabled and a signal is transmitted to drive the member 10 until coincidence occurs. NOR gates 94, 100 in the first circuit associated with the next most significant commutator track are then primed so that the movable member is again moved until coincidence occurs between the bit sensed by brush 66 and the next most significant digit of the input command signal. This process is repeated for the tracks 14 and 12, coincidence in the lowest significant commutator track resulting in a stop signal being given. When coincidence occurs in the commutator track 16 a signal is given to slow the drive speed of the movable member 10.
