Title: Improvements in devices for converting rotation-reciprocating linear motion to rotary motion or vice versa
IPC: F16F15/26
Filed: 1969-01-17
Abstract: 1,261,546. Balancing machinery; converting rotary motion into reciprocating motion. SHIZUOKA DAIGAKU CHO. 17 Jan., 1969 [30 Jan., 1968 (2)], No. 2740/69. Headings F2Q and F2X. [Also in Division F1] In a mechanism for converting reciprocating linear motion to rotary motion or vice versa for machine tools, riveters, chisels, hammers or cutters and sewing, spinning, weaving and spring-testing machines, a crank-shaft is journalled in at least one eccentric collar means rotatably supported by the casing of the machine and having an eccentricity equal to that of the crank-pin, the eccentric collar means being arranged by means of an eccentric-gear or hypocycloidal mechanism to rotate at the same angular velocity as the crank-shaft but in the opposite direction so as to provide linear motion of a rod connecting the crank-pin to a reciprocating member, and balance weights are secured to the crank-shaft and the eccentric collar means. The mechanism is described as applied to an I.C. engine, Figs. 6 and 7, comprising a crank-shaft 4 journalled in eccentric collars 5, 6 which in turn are journalled in bearings 13. A gear 12 on the crank-shaft meshes with an eccentric gear 25 on a shaft 23, and a gear 24 on the shaft 23 meshes with a gear 18 on an output shaft 17. The gear 18 and a further gear 19 on the shaft 17 mesh with respective gears 15 and 16 to cause the eccentric collars 5, 6 to rotate at the same speed as the crank-shaft 4 but in the opposite direction. The effect of this arrangement is that the piston-rod 1 moves in a straight line along the cylinder axis. Balance weights m 1  and m 2  are provided. In another embodiment, Figs. 8 and 9 (not shown), the mechanism providing straight-line motion is of the hypocycloidal type comprising planet gears (40, 41) on the crankshaft (33, 34), meshing with stationary annulus gears (42, 43) having twice as many teeth as the planet gears. An output shaft (48) is driven from the eccentric collars (36, 37) through gearing (44, 46) and (45, 47). The piston-rod can be divided for the insertion of a spring means for accommodating torque variation.

Title: Improvements relating to electric control systems for electric motors, steam engines and other prime movers
IPC: B66B1/12
Filed: 1945-02-05
Abstract: 588,209. Automatic control systems for winding gear &c. BRITISH THOMSON-HOUSTON CO., Ltd., and PETCH, T. H. Feb. 5, 1945, No. 2888. [Class 38 (iv)] [Also in Group XXXVII] Speed.-An electric motor, steam engine, or other prime mover, particularly one driving a lift or hoist, has a master controller and an auxiliary controller automatically maintaining the speed of the prime mover at that set by the master controller, and actuated by an electric motor fed from an auxiliary generator, the excitation of which is responsive to the setting of the master controller and to a tachometer generator driven by the prime mover. The auxiliary generator is preferably an amplidyne A of the kind described in Specification 539,835, the output of which is controlled by two main fields, one 5, 'excited through the master controller M.C. at a constant value, but reversible according to the direction of rotation selected, and the other 4, excited by a tachometer generator T.G. in series with a resistance R varied by the master controller, which may be of the type described in Specification 494,900, [Group XXXVII]. Should the prime mover not run at the speed set by the master controller, the differential excitation of the amplidyne will cause the auxiliary motor M. to operate correcting means. As shown in Fig. 1, this comprises resistance L.C. in the rotor circuit of an induction motor I.M., constituting the controlled prime mover and also a dynamic braking contactor D1, which introduces on negative loads (i.e. a load assisting the motor torque) braking by D.C. excitation or by a kind of low-frequency A.C., as described in Specification 516,666, [Group XXXVII]. Sets of contacts 16, 17 and 25, 26, in the master controller and the auxiliary controller ensure return of the latter to a neutral position after the motor has stopped and the control lever has been returned to neutral. Overload and anti-hunt fields 6, 7, are provided on the amplidyne. The auxiliary controller may actuate means for controlling prime movers other than electric motors by some form of directional and braking control: the resistance L.C., for example, may be replaced by a throttle control.

Title: Improvements in and relating to sound records
IPC: G03C5/14
Filed: 1936-01-31
Abstract: 455,543. Photographic and photomechanically produced sound records. KOLB, O. K., 39, Beverley Court, Wellesley Road, Chiswick, London. Jan. 31, 1936, No. 2940. [Class 98 (ii)] A record produced on a continuous film is duplicated by dividing it into short lengths having oblique ends, arranging these lengths in parallel relation in a frame or drum, printing them photographically or photo-mechanically upon a sheet, cutting up the sheet to separate the prints, and joining the sections or mounting them on a backing-strip to form a continuous record strip. The sections P1 ... P10, Fig. 1, of the original may be secured to a transparent backing P, so that a negative in sheet form is obtained. To economize printing material, the sections may be arranged with their oblique ends collinear, so that the negative takes the shape of a rhombus. The negative may be printed on diazotype or ferroprussiate sensitive paper, or may be used to produce a flat or roller-type photo-mechanical printing surface. Identification marks are made at the ends of the sections on the negative to ensure correct assembly of the prints. The oblique cuts serve to minimize unwanted noise when the joints of the print pass through the sound reproducing apparatus; and further improvement in this respect is obtained by using double-hump tracks, preferably in multiple, as at R4, Fig. 4.

Patent GB-345408-A (GB)
IPC: C08B3/28
Filed: 1930-01-29
Abstract: Cellulose acetates and other organic esters of cellulose as obtained by precipitation from the acidylation solutions, with or without previous ripening, are separated into their constituents by fractional precipitation.  In general, the fractions that precipitate first have a higher clarity, a greater resistance to heat, and higher viscosity characteristics than the esters that separate towards the end of the precipitation.  A convenient method of effecting the separation involves the use as a solvent in preparing the solution of the cellulose ester, of a liquid medium, such as a mixture of benzene and methyl or ethyl alcohol, which at ordinary temperatures has little or no solvent action on the ester; separation is effected by cooling the hot solution, either rapidly in order to obtain as a first fraction the bulk of the ester, or alternatively the cooling may be gradual so that the main bulk is separated in fractions.  In the case of cellulose acetates, acetone, or mixtures of benzene and methyl or ethyl alcohol are suitable solvents, and to the solutions water or other non-solvents may be added.  Suitable solvent mixtures consist of 70-35 parts of benzene and 30-65 parts of methyl or ethyl alcohol, mixtures of equal volumes giving satisfactory results.  In examples, the decomposition temperature of an acetone-soluble cellulose acetate is raised by collecting the acetate separated in cooling solutions prepared by heating the acetate with benzene-methyl alcohol-water or benzene-ethyl alcohol mixtures. The mother liquors may be used for dissolving a fresh quantity of cellulose acetate, and the products separated may again be subjected to solution and precipitation.  It is convenient to employ solutions of 5,15 per cent, particularly of 10 per cent concentration.
