Title: Improvements in or relating to agitators for suction cleaners
IPC: A47L9/04
Filed: 1939-01-27
Abstract: 524,437. Vacuum cleaners. HOOVER, Ltd. (Hoover Co.). Jan. 27, 1939, No. 4635/40. Divided out of 524,317, under which a Specification was laid open to inspection under Sect. 91 of the Acts, July 29, 1939. [Class 8 (i)] The brush 5, Fig. 1, of the rotary agitator of a vacuum cleaner is advanced as the bristles wear away in use, under the control of a feeler 62. When the brush is so worn that the feeler contacts with the carpet, it is rotated, releasing a tooth on the brush stock from the roller 68, and allowing the brush to advance half a tooth pitch until held by the pallet 69 ; a spring 70 then pulls the feeler back to its former position , releasing the pallet 69 from its tooth and allowing a further half tooth pitch advance. In another form, the feeler moves a ratchet to shift a plate having a stepped slot, the steps holding a pin on the brush in consecutive positions ; alternatively, the ratchet actuates the head of a screw engaging the brush stock. In another form the feeler engages a ratchet wheel carrying a cam which acts directly or indirectly on the brush; the cam may be constituted by a curved rack on the brush body. Fig. 4 shows ball wedges replacing ratchets ; the balls 86 prevent the brush moving inwards pressure on the feeler 62 allows the balls 88 to move freely backwards, and the brush is again carried forward with the feeler under centrifugal force assisted by a spring ; in a modification, the ball wedges 86 are replaced by a spring pushing the brush forward. Fig. 8 shows a feeler 62 mounted on a counterweighted bellcrank lever carrying a pawl 107 acting on a combined ratchet and cam 105, 106 co-operating with a pin 108 on the brush. Normally the feeler rests against the end of the brush and is withdrawn into the agitator body as the speed of rotation increases. When the brush is worn the feeler passes over the brush end permitting the pawl to advance a tooth, with consequent advance of the brush.

Title: Process of preparing a dibenzopyran derivative having marihuana activity
IPC: C07D311/80
Filed: 1942-04-15
Abstract: Dibenzopyran derivatives possessing marihuana activity are prepared by condensing pulegone with a 1 : 3-dihydroxy-5-R1-benzene under such conditions of time of refluxing and/or amount of condensing agent as to result in an optically active derivative.  R1 is either hydrogen or an alkyl group with 1-10 carbon atoms.  The preferred condensing agent is phosphorus oxychloride.  The 1 : 3-dihydroxy-5-alkyl-benzenes may be prepared as described by Suter and Weston J. Am. Chem. Soc., Vol. 61, page 232.  In examples: (1) Pulegone is condensed with orcinol in the presence of phosphorus oxychloride in benzene solution to give an optically active product. Variation in the amount of phosphorus oxychloride results in a variation of the optical activity of the product. (2) Pulegone is condensed with olivetol in the presence of phosphorus oxychloride in benzene solution and worked up to give an optically active tetrahydro-cannabinol which is an isomer of the compound obtained by the process of Specification 558,554.  As in example (1), the optical activity of the product varies according to the amount of phosphorus oxychloride used.  (3) Pulegone is condensed with 1 : 3-dihydroxy-5-n-butyl benzene as in example (1) to give-1-hydroxy-3-n-butyl-6 : 6 : 9-trimethyl-7-8-9-10-tetrahydro-6-dibenzopyran.  (4) Pulegone is condensed with 1 : 3-dihydroxy-5-n-hexyl - 6 : 6 : 9-trimethyl-7-8-9-10-tetrahydro - 6 - dibenzopyran.  The corresponding compounds may be obtained by using the appropriate iso-amyl, heptyl or octyl derivatives of 1 : 3-dihydroxy benzene.

Title: Electropainting process and paint binder concentrate composition therefor
IPC: C09D5/44
Filed: 1963-02-07
Abstract: In the process of electrophoretic coating as disclosed in the parent Specification using an apparently water-soluble and clear dispersion of a film-forming paint binder consisting of a polycarboxylic acid resin partly neutralised with a water-soluble amino-compound, the dispersion includes particles of the neutralised resin up to 500 millimicrons thick which may render the dispersion hazy.  The pH of the dispersion is maintained either at 5 to 7 or at 8.2 to 8.4, by suitable replenishment additions of an aqueous concentrate of the amino-compound and polycarboxylic acid resin which together maintain the resin in "polyelectrolyte" condition i.e. the electro-phoretic deposit formed is directly proportional to the current applied and is independent of the voltage. During coating the excess of amino compound formed may be removed by electrodialysis, or by adding organic acids e.g. malic, citric, or acids having 12 to 44 C atoms which form soaps, which are co-deposited on the anode surface. This may be metal or other conductive surface in the form of wire, sheet, tube, perforated metal or articles. The dispersion contains resins, amines, solubilizing agents, viscosity reducers, pigments, and deoxygenating compounds, all as described in the parent Specification.  A similar apparatus is also described.
