Title: Radio aerials
IPC: H01Q1/10
Filed: 1970-10-13
Abstract: 1313676 Aerials YOKOWO MFG CO Ltd 13 Oct 1970 [13 Oct 1969 28 Dec 1969] 48579/70 Heading H4A A device for raising and lowering an extensible aerial 8 comprises a flexible rod 9, made of a synthetic resin or the like, one end of which is connected to said aerial, and the other end of which is connected to an internal drum member 7b, upon which it may be wound by an electric motor 5. An external drum member 7a extends over the winding surface of the internal drum member 7b, so that there is a space between the drum members in which the wound-up rod is contained. A ratchet mechanism comprises a ratchet wheel 7d carried by the drum member 7b and a pawl 7e carried by the drum member 7a, which only engages with the ratchet wheel when the rod is being unwound. During the winding-up operation the external drum member is disengaged from the internal drum member. A base 1 supports the motor 5 and a container 18 for the aerial 8, and has a cup-shaped portion with a cover 16 for the winding mechanism. The internal drum member 7b is keyed to a hollow shaft 3, which is rotatable upon a central pin 2. A worm 6 is driven by the motor 5, and is coupled to a worm wheel 4 which is rotatable upon the shaft 3. A rotary disc 10 is axially slidable upon the shaft 3, and has a projection 10a which may engage in either of two grooves 4a, 4b in the wheel 4, and which is coupled to a movable contact 12 of a switch which also comprises fixed contacts 13, 14. A coiled spring 11 presses the disc 10 against the wheel 4 and also transmits drive to the internal drum member 7b. In operation, when the rod 9 becomes fully wound-up or fully unwound, as the case may be, a sudden increase of load is experienced, and the projection 10a moves from the groove 4a to the groove 4b, or vice versa. The consequent axial movement of the disc 10 changes over the contact 12 from one to the other of the contacts 13, 14. This switches off the motor 5, and prepares a circuit for the next operation (Fig. 4, not shown). The aerial may be fitted to a motor vehicle.

Title: Determination of rate of consumption of gases dissolved in liquids
IPC: C12M1/34
Filed: 1965-11-17
Abstract: 1,132,457. Measuring oxygen content of liquids. WALLACE & TIERNAN Inc. Nov.17, 1965 [Nov.17, 1964], No.48902/65. Heading G1N. [Also in Divisions C6 and F1] The rate of consumption of dissolved oxygen in an aerobic biological culture is determined by passing a sample of the culture past a first oxygen detector and then, after a time delay #T during which no oxygen is admitted to the sample, past a second oxygen detector and subtracting the output of the second detector from that of the first. Sufficient oxygen must be present initially for the oxygen consumption to take place at a constant rate. If the concentration of dissolved oxygen at the first detector is changing slowly, the output of the second detector may be directly subtracted from that of the first. However, if the concentration of dissolved oxygen at the first detector is changing rapidly, it is necessary to provide a time delay, equal to #T, between the output of the first detector and the subtracting circuit. The sample may pass first through a mechanical screen (32) and aeration tube (26) and then past a first polarographic oxygen detector (50), a positive displacement pump, and a second polarographic oxygen detector (52). Stirrers (57a), (57b) rotate beneath the detectors and may have flexible bristles (91a),  (91b) which brush the bottoms of the detectors. A valve (68) is provided to enable the pump to suck liquid in past both detectors for calibration purposes. The pump comprises two meshing resilient plastics screws and, in effect, pumps discrete packets of fluids. The outputs of the detectors are fed via amplifiers having thermistor feedbacks to correct for the temperature characteristics of the detectors. The time delay #T may be provided by a magnetic tape loop.

Title: Improvements in or relating to process for the electrolytic and electro-chemical working of metals
IPC: B23H3/08
Filed: 1963-12-11
Abstract: An electrolytic process for the working of metallic workpieces (including metallic carbide workpieces wherein the workpiece is employed as an electrode spaced apart from another electrode, there being relative motion between the electrodes towards one another during the working, material removal being effected by an electric current flowing through both electrodes through the intermediary of a non-corrosive electrolytic solution provided between the electrodes and having an essential component selected from the group consisting of water soluble fluorides and fluoro-compounds.  A non-corrossive electrolytic solution is defined as one which in the absence of electric current removes substantially no material from the electrodes concerned in the process, e.g. a solution containing at least 4% by weight of KF. According to the materials to be worked, the electrolyte may be acidic, alkaline or neutral.  Additional salts which may be included in the solution are nitrites, nitrates, phosphates, carbonates, sulphates or salts of organic acids or bases. The working may be by electrolytic grinding using an abrasive disc or wheel or by electrolytic sinking using an electrode and a feed-control mechanism to hold the gap between the electrode and workpiece constant. The electrolyzing current may have periodic pulses of opposite polarity to remove passive layers which build up on the anodic workpiece. Surfaces and edges not to be worked during electrolytic working may be protected by lacquers or coatings of good electron conductivity comprising electron conductive pigment such as graphite, carbon, metal or alloy powder and an organic or inorganic binding agent.  The electrolytes used in deriving the graphs of the following Figures (not shown) contain 1) 15% by weight KNO3, 2) NaNO2-NaNO3 with organic additives, 3) NaNO2-NaH2PO4-sodium tetraborate, 4) 15% by weight of KF.
