Filed: 1960-10-24
Abstract: Titanium chelate compounds of the general formula: (RO)xTi(R1)4-x where x=0, 1, 2 or 3 and R is an alkyl or aryl radical, e.g. ethyl, n- or iso-propyl, n, iso, sec. or tert. butyl, 2-ethylhexyl or phenyl, and R1 is an oxy-compound capable of chelating with titanium, e.g. dihydroxy, diketo, hydroxy keto compounds, hydroxy carboxylic acids and their esters and keto carboxylic acids and their esters may be made by mixing one mole of a titanium ester e.g. tetraisopropyl titanate or tetraisobutyl titanate with 1, 2, 3 or 4 moles of the appropriate oxy-compound and removing the liberated alcohol. In examples, ethyl acetoacetate titanate is made (Example 3) by mixing one mole of tetraisopropyl titanate with two moles of ethyl acetoacetate and distilling off the liberated isopropanol in vacuo, or (Example 4) by mixing one mole of tetraisopropyl titanate with four moles ethyl acetoacetate, four moles of isopropanol then being distilled off. Acetyl acetone titanate is made (Example 6) by mixing one mole of tetrabutyl titanate with two moles of acetyl acetone. Similar methods may be used for the preparation of diacetone alcohol titanate and octylene glycol titanate.ALSO:A cigarette filter is made from a tow of 18,000 cellulose acetate filaments each of 0.8 denier, which is crimped to 20 crimps per inch, spread out to a width of two feet and sprayed with glycerol triacetate plasticizer to an increase in weight of 12%.  The tow is then compacted into a cord and processed into filter rods in conventional manner.  Cigarette filters 15 mm. in length are made from the rods and attached to cigarettes, which are smoked on a standard cigarette smoking machine.  Analysis of the smoke yields only one half the tar and nicotine content found in the smoke from the same cigarettes without the filter.  The filaments comprising the filter are made from a cellulose acetate spinning solution, containing preferably 15-23% cellulose acetate, the viscosity of which has been increased by dissolving therein a small proportion of a titanium chelate compound.  For details see Division B5 abridgment.

Title: Improvements in or relating to telescopic struts
IPC: B60G17/027
Filed: 1965-09-02
Abstract: 1,099,154. Self-levelling shock-absorbers. ALFREDTEVES MASCHINEN - UN ARMATURENFABRIK KOMM. GES. Sept. 2, 1965 [Dec. 2, 1964], No. 37516/65. Heading F2S. A self-levelling telescopic strut, particularly for motor vehicles comprises resilient means, preferably a helical spring 34, for springing the wheels in relation to the vehicle body, a piston 23 and cylinder 30, 31, hydraulic vibration damper, and a spring stressing piston 6 and cylinder 7 hydraulically operated by an automatic level control system for vertical adjustment of the vehicle body, a passage 36, 39, through which the liquid flows from the pressure chamber 9 of the spring-stressing cylinder 7 into the working chamber 28 of the hydraulic vibration damper at a downwards adjustment, being sealed by a valve 10 as long as a rod 20 for the piston 23 is below its desired vertical position. When the strut telescopes, below its desired vertical position, a pump plunger 24 and suction valve 21 co-operating with the hollow piston-rod 20, pumps liquid from the pressure chamber 28, through a oneway valve 8 in the spring-stressing piston 6, and into the pressure chamber 9 of the cylinder 7, which bears against the upper end of the support spring 39 by means of a collar 38, the stressing on the spring 34 being increased. As the piston 23 rises the passage 36, 39 remains sealed by the valve 10 only as long as the piston 23 stays below its desired vertical position. Above this position the pump plunger 24 disengages from a sleeve 19, which encloses and prestresses a spring 18 to urge the valve rod 10 upward, the latter opening the passage 36, 39 so that liquid can flow from the pressure chamber 9 to the passage 12 within the rod 20 and then to a working chamber 28 of the strut. A second weaker spring 32 controls the flow of liquid from the chamber 9 to the chamber 28. The maximum distance A travelled by the spring-stressing cylinder 7 is limited by an annular stop 11. The leakage of oil from a gasket 37 flows through a passage 5, and the leakage of oil from gaskets 17, 35 flows directly into a collecting chamber above a closure cap 16 and then, through passages 15, into a reservoir 29. Rubber bellows 3, 14 prevent any soiling of the leakage oil, a tube 13 supporting the bellows 14. A collar 33 on the casing 31 of the strut supports the lower end of the spring 34.
