IPC: B06B3/00
Filed: 1921-12-08
Abstract: 193,997. Stringer, H. L. Dec. 8, 1921. Machinery, utilizing inertia to obtam movements in. - Relates to means for converting vibratory motion into rotary motion, applicable for actuating moving advertisements by utilizing the vibrations produced on or bv vehicles &c. According to the invention a weight a mounted on a spring b is attached to one end of a thread or cord e passing over or round a pulley f and tensioned at the other end by a light spring g so that the pulley f is driven in one direction of rotation only under the influence of the movements produced in the weight a by external vibrations. Two or more weights may drive the same shaft, preferably being equidistantly disposed around the shaft. In order to prevent back rotation when a single. weight is used, a second cord i is passed over the pulley, being corrected at one end to the rigid frame or box d and at the other end to a spring j, this arrangement allowing rotation in a. clockwise direction only.

Title: Improvements in or relating to apparatus for regulating the effective output of internal combustion engined vehicles with electric power transmission
IPC: H02P9/00
Filed: 1946-11-11
Abstract: 618,666. Transmitting mechanical power. SULZER FRERES SOC. ANON. Nov. 11, 1946, No. 33441. Convention date, Nov. 15, 1945. [Class 38 (iv)] [Also in Group XXVII] In a supercharged internal-combustion engine 1 driving a vehicle through electric power transmission 2, 3 and having a governor 15 for maintaining the engine speed constant at a value set by a hand wheel 17, the movement of the fuel pump control rod 35 by the governor 15 to increase the fuel supply is limited by a stop 34 adjusted by the wheel 17 and by a second stop 40 positioned by a capsule 43 subject to supercharging pressure. Rotation of the wheel 17 to increase speed sets the governor-loading spring 21 to a higher value and moves the stop 34 through levers 27, 28 to the left to increase the range of adjustment of the control rod 35, the governor moving the rod 35 to the left, when the speed drops due to increased load, until a spring-connection casing 39 contacts the stop 34. The stop 40 is normally held out of the path of movement of the rod 35, but if the drop in speed is such that the supercharging pressure, provided by an exhaustdriven supercharger 44, drops below the safe value for the amount of fuel being injected, the capsule 43 expands, moving the stop 40 to contact rod 35 and reduce the fuel supply. A solenoid 37 is energized on closing of a starting switch 36 to raise a rod 38 and move the stop 34 into a position allowing the rod 35 to be moved into its maximum fuel supply position. The engine 1 drives a main generator 2 feeding traction motors 3, and an auxiliary generator 4, and the wheel 17 controls resistance regulators 12, 7 in the shunt and excitation windings 11, 6 of the generator 2, and a regulator 25 in the field winding of the generator 4. At starting, the auxiliary generator 4, controlled by a voltage regulator 26, is rotated by starting apparatus and on rotation of the wheel 17 to increase speed a contact drum 22 closes terminals 46 to operate a relay 10 to excite the generator 2. The solenoid 37 may be controlled by the relay 10 instead of by the starting switch 36.

[Also in Divisions C7, D1, G2 and H1] Glass articles (of Examples 1, 6 and 7) are coloured using stable solutions of the reaction product of a hydrolysable organic titanate and an aromatic dye e.g. xanthene or phthalein dyes, together with a stabiliser. The term "solution" includes fine, clear, colloidal dispersions. The preferred solvent is methanol, which may contain 10% water, and the solution contains not more than 40% by weight of solids. The titanates used have the formula (RO) 4 Ti wherein R is C 1 -C 18  alkyl e.g. tetraisopropyl titanate. Stabilisers used are inorganic metal salts e.g. copper halides, nitrate, sulphate, and acetate; aluminium, lead, antimony and trivalent titanium halides, nitrates and sulphates; and also citric and acetic acids and lithium, sodium and potassium hydroxides. The articles are dipped in the solution, withdrawn at a predetermined rate e.g. 10-30 inches per minute, and then heated to approximately 400-450F to bake and cure the coating which has a preferred thickness of 200 to 5000A.

A bearing assembly for a rotatable shaft 1 (Fig. 1, not shown) comprises a pair of taperroller bearings 4, 5 which are separated from one another by a pair of spacer rings 6, 7 made of different materials, e.g. nickel-iron alloy and bronze, to effect substantially constant clearances in the bearings by compensating for differences in the thermal expansion of the inner races 13, 16 and the outer races 14, 15 due to dissimilarity in the rates at which the races dissipate heat generated when the shaft rotates, the coefficients of thermal expansion of said materials being appropriate to the materials and heat-dissipation rates of the adjacent races. The outer races are retained in a housing 2 by a ring 3 secured by a plurality of bolts 40, whereas the inner races are retained on the shaft by a pair of nuts 9, 10 and a resilient ring 8. Alternatively, the assembly may comprise a pair of ball bearings 24, 25 (Fig. 2, not shown) of the cup-and-cone type. One of the spacer rings may be made of carbon steel instead of a nickeliron alloy.
