Title: Deceleration Controlling Apparatus for an AC Elevator
IPC: B66B1/44
Filed: 1969-01-30
Abstract: 1,195,663. Control of A.C. motors. HITACHI Ltd. 30 Jan., 1969 [7 Feb., 1968], No. 5137/69. Heading H2J. In an A.C. elevator system in which a deceleration command signal is produced when the cage is at a predetermined distance short of a required floor, actual deceleration is delayed by an amount which is greater when the cage is running in a short floor interval mode (e.g. between adjacent floors) than when it is running in a long floor interval mode. The object is to prevent unduly long running at low speed and the abrupt change of torque which would occur if deceleration is initiated before the cage has approached full speed. The drive comprises a two speed, pole-changing induction motor and deceleration is effected by switching to the lower speed to produce regenerative braking. In one embodiment (Figs. 2 and 3, not shown) the mode of running is detected by a relay circuit which compares the calling floor with the destination floor but in Fig. 6 (not shown) a delayed relay detects whether the deceleration command is issued before or after a prescribed time from the start of travel. In either case the delay for short floor interval running is fixed and is determined by a delayed relay with break contacts in the high speed contactor circuit which are short circuited when long floor interval running is detected.

Title: Improvements in method and apparatus for the conversion of gases into another substance by partial oxidation
IPC: C07C29/00
Filed: 1934-02-19
Abstract: <PICT:0428406/III/1> Reactions such as the oxidation of methane to methanol are performed in a gas engine having means for varying the ratio of air and gas without involving throttle control, means for varying the compression while the engine is working, and speed-regulating means involving control of the exhaust valve.  The engine is operated normally until a sufficient speed is attained; the ratio of fuel to air and the compression are then increased and the ignition is discontinued, whereupon self-ignition and partial combustion of the mixture take place.  The pressure on the reaction product should be suddenly released to avoid the occurrence of cracking.  Auxiliary fluids may be introduced at suitable points of <PICT:0428406/III/2> <PICT:0428406/III/3> <PICT:0428406/III/4> the cycle to produce the optimum conditions of temperature and pressure. Driving-gear.--The size of the compression chamber is varied by screwing the piston rod 24 to a variable extent into the hub 26 of the cross-head 13.  For this purpose the rod is provided with longitudinal ribs 27, Fig. 5, splined through a worm wheel 28 which is rotatably mounted in a recess at the inner end of the cylinder and is operated by a worm 29 and handle 31.  Regulating.--The methane admitted by the valve 58, Fig. 6, passes through the annular space 64 and is mixed with air entering at 34 before reaching the inlet valve 38.  A sleeve 63 surrounding the space 64 may be raised or lowered to vary the sizes of the fuel and air ports without affecting the total quantity of mixture. Fig. 4 shows the speed-regulating device, which puts the exhaust valve out of action at excessive speeds.  The valve tappet 81 is mounted on a crank 80 which is operated by the cam-actuated push-rod 94 through the medium of a trip 84.  This is pivoted on an arm 96 to which the push rod is connected by a ball and socket joint.  It eomprises a blade 98 adapted to engage a shoe 83 on the crank arm, and a weight 97 acting in opposition to a spring 100. At excessive speeds the inertia of the weight causes the trip to turn on its pivot so that the blade misses the shoe.

Title: An improved gyroscopic toy
IPC: A63H1/00
Filed: 1921-02-17
Abstract: 172,557. Ewest, H., and Bomborn, B. Feb. 17, 1921. Machanical toys; tops.-Relates to a toy of the type which, when rolled along the ground, travels a certain distance and then returns to the starting point. The invention consists in providing means whereby the casing of the toy, after rolling for a predetermined distance, is coupled to a rotating fly-wheel and either continues to run on at a higher speed or stops and then runs backwards. The toy may be used as a top, as a driv. ing-wheel for toy vehicles, or as a device for playing games. The toy, as shown in cross-section in Fig. 1, comprises a casing 1 having conical - projections 15, 16 in which is housed an axle 4. The projection 16 is partly cut away, as shown at 17, to permit a cord to be wound on a hub 19 to which a fly-wheel or heavy disc 3 is secured by means of a metal ring 18. A weighted pendulum 12, Figs. 1 and 4, loosely mounted on the axle 4 is provided with a tooth 14 which engages the teeth of a gear wheel 9 secured to a shaft 10. This shaft has an arm 11 which engages, when in the position shown, a stop 7 that is connected to the fly-wheel 3 by a coil spring 21. One end of the spring is secured to a sleeve 5 from which the stop 7 projects, while the other end of the spring bears frictionally against the inner surface of the ring 18. In use, the shaft 10 is turned by a knob 10<1> until the arm 11 takes up a predetermined position 11<1> or 11<11>, Fig. 4, and the wheel 3 is spun by a cord wound on the hub 19. If the casing now be rolled along the ground, the pendulum 12 will keep the tooth 14 upright and the wheel 9 will be rotated until the arm 11 strikes a stop 22. The stop 7 now strikes the arm 11 and the fly-wheel 3 is connected with the casing, which either travels forward at a higher speed or runs backwards, according to the direction of rotation of the wheel 3. The frictional connection between the spring 21 and the rim 18 diminishes shock when the stop 7 contacts with the arm 11. In a modification, the pendulum rotates with the casing but has a limited oscillation about its pivot. In a further modification, the wheel 9 is rotated by a spring, the pendulum being arranged to act as an escapement. A gap 23, Fig. 4, in the teeth of the wheel 9 enables the casing to be rolled along the ground without connecting with the wheel 3. The toy may be spun on the points of the projections 15, 16 like an ordinary top, on it may be used as a wheel for toy vehicles. When rolled along the ground it can be used for playing skittles.

The upper movement of the knives is limited by a shoulder 20 on the inside of the casing, which provides a stop for the top circle of the cylindrical. stripper side 17. Three holes 24 are provided for entry of rinsing water. The knives 4 are spaced by sleeves and can pivot slightly on their retaining bolt 6. The knives are formed with vertical stiffening ribs. The sides 19 of the blades are guided within the stripper sides 17 and when the stripper comes to rest on the food, the knives proceed downwards to chop the food. The rod 9 is long enough to allow at least the stripper bottom to be pushed out beyond the casing bottom to rinse the stripper and knife edges. The casing 2 may be made of transparent synthetic material.

Title: Improvements in the manufacture of moulding powders
IPC: C08J3/12
Filed: 1941-05-02
Abstract: 549,084. Moulding powders. DU PONT DE NEMOURS & CO., E. I. May 2, 1941, No. 5714. Convention date, May 2, 1940. [Class 2 (iii)] [Also in Group V] Granular moulding powders are made from a paste of a pulverulent CH  2  = C < resin, such as polystyrene, polyvinyl esters and esters of acrylic acid and its homologues, in a volatile non-solvent, preferably water, by passage between heated rolls at temperatures below that at which a continuous dough is formed and then comminuting the dried resin to granular size. Moulding compositions are produced of satisfactory bulk density having non-spherical granules, capable of giving moulded products of uniform colouration from uniformly coloured pulverulent resins. Examples describe the production of moulding powders by comminution of sheets or flakes obtained by repeated passage through heated rolls of aqueous emulsions of (1) polymethyl methacrylate, "Duponol ME" (the sodium salt of sulphuric esters of a mixture of coconut oil alcohols), stearic acid and benzoyl peroxide; (6) polymethyl methacrylate, dibutyl phthalate, "Duponol ME", butyl stearate, benzoyl peroxide and titanium dioxide paste; (8) polystyrene, "Duponol ME," benzoyl peroxide and a solution of dyestuff; and (9) polymethyl methacrylate, titanium dioxide, cadmium red and stearic acid. Other examples describe the addition of dyestuffs in solution or dispersion to the emulsions. The polymethyl methacrylate is obtained as a fine grai npowder by (2) polymerization of the monomer in methanol and water or (3) by precipitation from acetone, alcohol and water mixtures. The dyestuff which must be water insoluble may be added to the resin as a dispersion or solution in a minor volume of water-miscible solvent which is mixed uniformly with the resin before carrying out the process of the invention.

Abstract: 637,348. Exposure-counting mechanism for roll-film photographic cameras. KODAK, Ltd. Feb. 26, 1948, No. 5866. Convention date, March 7, 1947. [Class 98 (i)] Film metering mechanism for cameras using perforated film includes a sprocket having teeth spaced closer together than the film perforations and rotatably mounted to project at one side into a' film guideway, and means for feeding the film through the guideway to move the sprocket intermittently by the engagement of a tooth in a perforation to bring one of a series of numbers on the sprocket opposite an aperture in its support when the film is wound on, the next-following sprocket tooth engages the surface of the film, as the numeral moves beyond the aperture, and flexes the film so that, when the first-mentioned tooth is disengaged from its perforation, the sprocket remains stationary until the following perforation has engaged the following tooth. The device forms part of a camera in which the film is wound from a supply chamber, across an exposure aperture, and into a spool-less takeup chamber, and is re-wound into the supply chamber. Exposures may be made during winding or re-winding. As shown, the film F passes between walls 18, 19 spaced apart by a distance slightly less than twice the thickness of the film. A recess 22 is formed in wall 18 opposite the exposure aperture 9 which is formed in the wall 19. A sprocket 1 is rotatably mounted so that its edge projects through aperture 9 into recess 22. When a tooth 2 of the sprocket engages a perforation A of the film centrally in the aperture 9, one of a series of number (not shown) on the sprocket 1 is visible through an aperture in the camera wall. When the film is moved, sprocket 1 turns until the perforation is disengaged from the tooth and the next tooth bears against the unperforated margin of the film which is thereby bowed outward, and slides over the teeth of the sprocket, which remains stationary, until the next perforation engages the second tooth to move the sprocket until the next number appears in the viewing aperture.
