Abstract: 491,446. Adjusting wireless apparatus ; variable-speed gearing. GENERAL ELECTRIC CO., Ltd., and SPEIRS, R. W. Feb. 1, 1937, No. 2934. [Class 37] [Also in Group XXIV] The invention relates to known slow motion epicyclic ball bearing reduction drives for electric condensers and like tuning devices, for example as described in Specification 439,152,' wherein the driven member is connected to the cage of a ball or roller-bearing and the driving member to one of the races and the other race is constrained so that the balls or rollers rolling between the two races carry round the cage and with it the driven member. According to the invention two of these reduction drives are used in series and in one of them means, which automatically connect the driving member to the cage on continued rotation of the driving member are provided to reduce the reduction ratio thereof to unity for coarse adjustment. The condenser shaft 1 rotatably mounted in a frame 2 forms at its front end a cage 6 in which balls 7 are rotatably mounted between an inner race 8 carried by the driving shaft 9 and an outer race 10 adjustable by nuts 12 on bolts 13. The shaft 9 forms at its forward end a cage 14 in which balls 15 are rotatably mounted between an inner race 16, carried on the driving shaft 17 of the adjusting knob 4, and an outer race 18 adjustably mounted by nuts 20 on a disc 22 rigid with the cage 6. For coarse adjustment, the shaft 8 is turned directly by the adjusting knob 4 through a radial arm 25 on the shaft 17 of knob 4 engaging a projection 26 on the cage 14 whereby the condenser is adjusted through the first mentioned epicyclic reduction drive 9, 7, 10, 6, only. The condenser is coarsely adjusted to slightly beyond the desired position when for fine adjustment the knob 4 is turned backwards and the condenser driven backwards through both reduction drives in series. The disc 22 drives the station indicator.

Filed: 1934-01-31
Abstract: 422,366. Safety razors. ROLLS RAZOR, Ltd., and PEARSON, H. B., 255, Cricklewood Broadway, London. Jan. 31, 1934, No. 3248. [Class 30] [See also Group XXIII] In a self-sharpening razor having a stropengaging roller E for turning over the pivoted blade F at the end of each sharpening stroke, a bevel reversing-gear J is provided so that the cutting-edge may be pushed when honing and dragged when stropping. The reversing-gear is changed by longitudinal movement of a spindle D, passing freely through the roller E and providing pivotal support for side-lugs G<1>, G<2> of a blade carrier G. The gear comprises a bevel-wheel, K secured to or integral with the blade-carrier lug G<1>, a bevel-wheel I, secured to the roller E, and bevel-pinions J, carried on a transverse pin J<1>, passing freely through an open-ended slot in the spindle D. In the position shown in Fig. 4, the slot in the end of the spindle engages a rib L on the side of a fixed V-shaped supporting-frame B. The pin J<1> is thereby held stationary and the reversing- gear operates for stropping. By moving the spindle D to the right in its frame B, it is disengaged from the rib L and a key D<2> at its other end engages a keyway in the bladecarrier lug G<2>, so that the carrier and roller turn together for honing. A bifurcated clip M springs into grooves in the spindle D to hold it in either position. In the modification shown in Fig. 16 the reversing-pinions J are journalled on the fixed frame C outside the roller E, and in the forward honing position shown, a long spindle-key D<5> directly connects the roller E with the blade-carrier lug G<2>, the reversing bevel I being moved out of engagement. The thick or thin blade F, which is permanently or removably mounted in the carrier G, is held in the shaving position by side-lugs on a pivoted guard H, influenced by a double-acting bladespring H<2>, the guard being curved, as shown, so as to ride over the blade without damaging its cutting-edge. The roller E may, as shown in Fig. 4, be surrounded by a steel sleeve. Flat stropping and honing surfaces may be provided on the lid of a box for the razor. Instead of the guard shown there may be a guard extending along the front and sides of the blade to occupy a position on either side of the blade during honing or stropping.

Title: Improvement in production of hydroxy derivatives of methacrolein dimer
IPC: C07C45/60
Filed: 1953-02-06
Abstract: The invention comprises hydroxy derivatives of methacrolein dimer consisting of 2,5-dimethyl - 2 - formyltetrahydropyrane - 5 - ol and 2,5 - dimethyl - 2 - hydroxyadipaldehyde.  They are produced by hydrolysing a -methacrolein dimer, preferably in an inert water-soluble solvent at a temperature between 0 DEG  and 150 DEG  C. in the presence of water and a strong acid.  During the hydrolysis a mixture of 2,5 - dimethyl - 2 - formyl - tetrahydropyrane - 5 - ol and 2,5 - dimethyl - 2 - formyltetrahydropyrane-6-ol are formed but the latter decomposes to form 2,5-dimethyl-2-hydroxyadipaldehyde. The neutralized reaction mixture from the hydrolysis reaction containing the 2,5-dimethyl-2-hydroxyadipaldehyde can then be hydrogenated, preferably under superatmospheric pressures of about 100 to 2000 lbs. per sq. in. and at temperatures in the range 25 DEG to 175 DEG  C. in the presence of a nickel, cobalt or copper chromite hydrogenation catalyst to give 2,5-dimethyl-1,2,6-hexanetriol.  In the examples: (1) a -methacrolein dimer, dioxane, water and sulphuric acid are heated together to give 2,5-dimethyl-2-hydroxyadipaldehyde and 2,5-dimethyl-2-formyl-tetrahydropyrane-5-ol; (2) a -methacrolein dimer, dioxane, water and sulphuric acid are heated together, the reaction mixture is neutralized and hydrogenated to give 2,5-dimethyl-1,2,6-hexanetriol.
