Title: Reduction gears
Inventor: SCHOTTLER HENRY
IPC: F16H63/06
Filed: 1967-02-07
Abstract: 1,149,411. Variable speed gear. ROLLER GEAR Ltd. ZUG. 7 Feb., 1967 [9 March, 1966], No. 5817/67. Headings F2D and F2Q. A constant speed or, as shown, infinitelyvariable reduction gear 20, Fig. 2, having input and output shafts 22, 23 comprises a deformable disc 50 rotatable with an axially movable output shaft 23 and deflected at segments on its periphery into engagement with a stationary housing 410 by two balls 60 in a freely rotatable carrier 70, constituting a pressure wave carrier, the balls 60 being driven by an input member 80. As shown in full lines the disc 50 is flat and, on rotation of the input shaft, no drive is transmitted to the output shaft. On rotating a nut 26, the shaft 23 is moved toward the input shaft 22 moving the disc 50 into the dashed line position. The pitch diameter dp of the disc, i.e. the diameter on the disc of the circular path that the balls follow, is then greater than the diameter dc and the balls 60 deflect the periphery of the disc into a substantially sinusoidal wave form, Fig. 6 (not shown), and on rotation of the input shaft the balls 60 roll and tend to " flatten-out " the wave form rotating the disc relative to the housing 41, and hence driving the output shaft at a reduced ratio of dc/dp-dc. One or more balls 60 may be used. Reduction ratios from co, i.e. no drive, to 200 : 1 are stated to be obtainable. Again, Fig. 7, rollers 172 on a freely mounted carrier 171 urge an initially bowed deformable disc 150 freely mounted on a rod 155, axially movable by screw means 105 to vary the ratio, against a ring member 160 mounted on hub 131 of the axially fixed output shaft 130. The disc 150 carries peripheral teeth 180 slidably engageable with a ring gear 182 fast with housing 101, those portions of the disc 150 adjacent the rollers being deflected out of engagement with the ring 182, but the remaining portions engaging the teeth to restrain the disc against rotation so that, on rotating the input member 170, the rollers again tend to " flattenout " the wave formation of the disc but, since the disc is held, the ring 160 rotates in the opposite direction to the input member rotating the output shaft through balls 190 held in recesses 165, 135 in the ring 160 and hub 131. Variation in a selected reduction ratio with load is prevented by the balls 190 which ride up the sides of recesses 165, 135 on increasing the load, urging the ring 160 axially to increase the pressure between the ring and disc 150 to prevent slipping. Reduction ratios from 300 : 1 to 60 : 1 are stated to be obtainable. The balls 60 and rollers 172 may be replaced by cams or sliding shoes (not further described).

Patent GB-726782-A (GB)
Title: Cation exchange resins
IPC: B01J39/18
Filed: 1952-03-06
Abstract: A cation-exchange resin is made by condensing at an elevated temperature and in an acid medium (1) one or more aromatic compounds which individually or between them possess different cation-exchange groups and at least one of which contains an etherified phenolic hydroxyl group with (2) one or more aldehydes or aldehyde yielding substances, continuing the condensation to form a gel and drying the gel at an elevated temperature. Specified starting materials to be condensed with an aldehyde are (a) the condensation product of 1 mol. of an aromatic aldehyde containing at least one carboxylic acid group with 2 mols. of an aromatic sulphonic acid containing at least one etherified phenolic hydroxyl group; (b) the triphenyl methane derivative of formula <FORM:0726782/IV (a)/1> obtained by condensing 2 mols. phenoxy acetic acid with 1 mol. of benzaldehyde-2,4-disulphonic acid; (c) a mixture of phenoxyacetic acid and the sulphonic acid of a polycyclic hydrocarbon (e.g. naphthalene or acenaphthene) or aromatic ether (e.g. diphenyl ether, anisole, diphenylene oxide or diphenylene dioxide).  When two aromatic substances are used they may be separately condensed with the aldehyde, the two condensates mixed and the mixture heated to form a gel; alternatively the lesser reactive aromatic compound may be precondensed with the aldehyde before adding the more reactive compound.  In examples: (1) the sodium salt of benzaldehyde-2,4-disulphonic acid and phenoxy acetic acid are introduced into 70 per cent sulphuric acid and later further phenoxy acetic acid is added.  When the condensation is complete the whole is condensed with formaldehyde to form a gel; (2) a mixture of sulphonated naphthalene, phenoxyacetic acid and formalin is condensed to form a gel; (3) a mixture of sulphonated acenaphthene, phenoxyacetic acid and formalin is condensed. Paraformaldehyde is then added, whereupon a gel soon forms.ALSO:A triphenylmethane derivative of formula <FORM:0726782/IV (b)/1> is made by condensing 2 mols. of phenoxy acetic acid with 1 mol. of benzaldehyde-2,4-disulphonic acid.  It is condensed with an aldehyde to yield an ion-exchange resin (see Group IV (a)).
