Abstract: The invention relates to a metering needle 1, which is intended especially for an automatic chemical analyser. The invention additionally relates to a metering process based upon the use of the said metering needle and to a process for production of the metering needle. The metering needle 1, which comprises a tubular shaft 2 and a flow duct 3 situated inside the same, is characterized according to the invention in that the flow duct 3, before the end 5 of the needle, emerges into at least one outlet opening 4, which is directed to the side of the longitudinal axis of the needle. The end 5 of the needle is preferably conically tapered and closed and the outlet openings 4 can be two or more in number, the said outlet openings being directed at even spacings to different sides of the needle. In metering which is carried out with the needle, the liquid flows issuing in the lateral direction produce a turbulent mixing of the liquid present in a vessel. The needle is produced by means of electroforming by separating out a metal layer onto a needle-shaped mould, working the metal into a needle and removing the mould from the inside of the needle. <IMAGE>

Patent GB-1141278-A (GB)
Title: Differential pressure-responsive device
IPC: G01L7/00
Filed: 1968-01-08
Abstract: 1,141,278. Valves. KINGMANN-WHITE Inc. 8 Jan., 1968 [18 Jan., 1967], No. 1021/68. Heading F2V. [Also in Division G1] In a fluid pressure responsive device differential pressures are applied to the device through bores 140, 142, assuming the higher fluid pressure is applied to bore 140, the pressure is communicated through a duct 144, an annular passage 172 between a damping snubber bore 164 and a piston 170 into a base cavity 24 and through a normally open pressure inlet controlled valve 125 into the inner portion of a bellows 56. The lower fluid pressure is applied through the bore 142, duct 150, an annular passage 172 between a damping snubber bore 164 and a piston 170, a duct 154 into an outer chamber 86 within a cover 16 externally of the bellows 56. The pressure difference internally and externally of the bellows 56 causes, if the internal bellows pressure is higher, the bellows 56 to expand and the upward movement of the bellows-closing plate 80 is transmitted through a helical spring 119 to deflect the centre portion of a flat spring 97 until the opposing forces of the spring 97 and the bellows plate 80 reach equilibrium. The static pressure exerted by the spring 119 up to the equilibrium stage maintain a valve seal 118 of a travelling valve 100 in closed relation to a valve aperture 82 in plate 80 and at the same time a flexible drive chain 130, attached to the lower end of the valve 100, rotates a drive sector 134 connected to a motion drive shaft 136. If an excessively high pressure is applied through port 140 relative to port 142, the bellows 56 is expanded to a limit where the valve 125 is closed to cut off any further pressure supply from the cavity 24 to the interior of the bellows 56 and thus prevents further expansion of the bellows 56. Should the pressure within the bellows 56 increase for some reason such as temperature, the pressure acting on the plate 80 will lift the plate 80 off the seal 118 to relieve such pressure. If the fluid presure applied to the port 142 is excessively high relative to the pressure through port 140, the bellows 56 will contract and the folds 60 will be forced into fully closed, superposed, supporting contact with one another and the closure plate 80 will rest upon and be supported by an annular stop member 88. In the event of any further pressure increase through port 142, the seal 118 will be forced out of sealing contact with the plate 80 to relieve such pressure.

Abstract: 450,815. Substation equipment. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Jan. 13, 1936, No. 1082. Convention date, Jan. 15, 1935. [Class 40 (iv)] In an arrangement for recording messages at an absent subscriber's station, a tone signal is sent to the calling subscriber either continuously or periodically as long as the recording machine is running, but is prevented from being recorded. As shown, the motor 12 is started by the operation of relay 4 in response to one or more pulses of ringing current. A switch 10 brings into circuit a talking head 15 which reproduces an announcement of the subscriber's absence from a record 11 and then connects through to a recording head 18. A magnet 21 cooperates with a phonic wheel 20 driven by the motor 12 to transmit a weak tone to the calling subscriber. To prevent recording of this tone, a filter 22 is inserted, or a balanced transformer arrangement is employed. The tone may be used to announce the absence of the subscriber, in which case it is weakened when the recording device is brought into circuit by the insertion of a resistance.

Abstract: 1,176,021. Pulse radar. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 10 Jan., 1967 [18 Jan., 1966], No. 1277/67. Heading H4D. Relates to " comb filters," which have a response characteristic of the form indicated by Fig. 2b in which the time T represents the repetition period of the signal to be filtered, zeros of the response recurring at frequencies corresponding to integral multiples of 1/T. A known comb filter, Fig. 1, comprises delay lines 11 . . . 14, each affording a delay T to the input 1 of which is fed e.g. detected coherent echoes in a pulse radar. An amplitude-weighting resistor network is incorporated and a subtractor 15, the filtered signal output appearing at terminal 2. In another known comb filter, the input signal is coded digitally and outputs from digital delay devices are sent to a computer, Fig. 3 (not shown). According to the invention a calculator 44, Fig. 4, works out an intermediate weighted sum with the weighting coefficients corresponding to a simple shift of the decimal point, e.g. in a binary code. Fig. 5a (not shown); accuracy and rapidity are thereby achieved. The outputs of calculator 44 and digital delay devices 431 . . . 435 are decoded and an analogue sum formed, Fig. 5c (not shown). The response of the whole filter is shown by the dotted line of Fig. 5b. In the application of the invention to a pulse M.T.I. radar which produces a coherent bi-polar echo signal output, each digital delay system comprises a memory and a shift register, Fig. 6 (not shown).

Title: Process for producing halogen-containing aromatic-aliphatic polyethers
IPC: C08G65/34
Filed: 1958-01-14
Abstract: In a process for the production of halogen-containing aromatic-aliphatic polyethers, polyhalogen aromatic compounds containing at least three halogen atoms attached to the aromatic nuclei are reacted with aliphatic, cycloaliphatic or aromatic-aliphatic diols with a molecular weight of at least 104, in the presence of alkalis.  As polyhalogen compounds chlorinated benzene, diphenyl and naphthalene and also fluorinated and brominated aromatic hydrocarbons are specified.  Diols specified are 1,5-pentanediol, 1,6-hexanediol, di- or tri-ethylene glycol, 2,2 - dimethylpropanediol, 2 - ethylpropanediol, 2,2 - (4,41 - dihydroxydicyclohexyl) - propane, quinitol, p - xylyleneglycol, the di-(hydroxyethyl) or di-(hydroxypropyl)-ethers of hydroquinone, tetrachlorohydroquinone, resorcinol, pyrocatechol, 4,41 - or 2,21-dihydroxydiphenyl, 1,2 -, 1,4 -, 1,6 - or 2,6-dihydroxynaphthalene or of 4,41-dihydroxydiphenyl alkanes.  The aromatic nuclei of the diols can contain alkyl, alkenyl or halogen substituents.  Also suitable are partial etherification products (e.g. allyl, methallyl, butyl or benzyl ethers) of polyhydric alcohols such as trimethylol propane, glycerol, hexanetriol, or pentaerythritol.  The reaction can be effected in inert solvent with azeotropic distillation of water formed, foaming being prevented by such agents as isopropyl naphthalene sulphonic acid sodium salt.  The products can be clarified by treatment with reducing agents such as "Rongalite" (Registered Trade Mark), sodium dithionite or sodium bisulphite. Examples describe the preparation of polyethers from hexachlorobenzene and (1) the di-b -hydroxyethyl ether of 2,2 - (4,41 - dihydroxydiphenyl)-propane; (2) 1,6 - hexanediol; (3) 2,2 - (4,41-dihydroxydicyclohexyl) - propane; (4) 2,2 - dimethylpropane diol; (5) di - b  - hydroxyethyl ether of 2,2 - (3,31 - diallyl - 4,41 - dihydroxydiphenyl)-propane; (6) the monoallyl ether of trimethylolpropane; (7) diethylene glycol.
