Patent CA-1047253-A (CA)
Inventor: HOLDEN JOHN E
IPC: A63H29/20

Granted: 1979-01-30
Abstract: ABSTRACT OF THE DISCLOSURE        An inertia motor for use in toys, comprising a drive gear mounted on one of the axles of the vehicle and having a substantial diameter and rotating a pinion gear which is coaxially mounted with a substantially larger back gear, which in turn drives a pinion which is coaxial with a flywheel, the flywheel being mounted eccentrically with respect to the drive shaft.  The flywheel is of such size and weight, and the gear ratios are such that the flywheel is rotated at least about twenty times with each rotation of the drive gear and, therefore, stores a sub-stantial amount of energy which is slowly released from the flywheel to the drive gear to provide a slow, prolonged release of energy to drive the vehicle.  In one embodiment of the invention, a pair of gear trains are provided, one on each side of the flywheel, in mirror image to each other, and the housing therefor, which may contain only two wheels, is in a substantially eliptical shape having a flattened bottom.  In this latter form, the device may be used alone as an inertia motor-driven toy, capable of gyroscopic action when placed on one of its two wheels and capable of being inserted in a second toy having a suitable enclosure opening, where the second toy is driven, or contains mechanisms driven by, the wheels of the inertia motor insert.

Preparation of the novel 1.alpha. , 24-dihydroxycholecalciferol and their derivatives starts from 1.alpha. , 24-dihydroxycholesterol prepared by reacting 1.alpha. , 2.alpha. -epoxy-24-keto-cholesta-4,6-dien-3-one with an alkali  metal and a proton donor in the presence of liquid ammonia or a liquid amine. Reaction of the 1.alpha. , 24-dihydroxycholesterol with an allylic bromina-ting agent, followed by contacting with a dehydrobrominating agent, affords 1.alpha. , 3.beta. , 24-trihydroxycholesta-5,7-diene derivative, which can then be converted to 1.alpha., 24-dihydroxycholocalciferol by ultra-violet irradiation in an organic solvent, followed by isomerization.          Processes are also provided for separating 1.alpha., 24-dihydroxychole-sterol into an (S)-epimer and an (R)-epimer, and also for separating at least one of 1.alpha., 3.beta., 24(S)- and 1.alpha., 3.beta., 24(R)-trihydroxycholesta-5,7-dienes fromtrihydroxycholesta-4,6-diene. .

Abstract: ABSTRACT OF THE DISCLOSURE         There is provided a transducer that is particularly useful for producing an output voltage from which the position of the core of the transducer and anything connected to it can be deduced.  The transducer includes a support member which has a hollow opening that receives a movable core.  A primary coil that can be connected to an AC source is mounted on the support member, while a secondary coil is mounted around the primary coil.  Axially spaced along the length of the secondary coil are a plurality of electrically conductive links that connect spaced turns of the secondary coil.  The ends of the secondary coil can be connected to output means which are responsive to the electric current induced in the secondary coil to generate an output voltage having predetermined characteristics.  The number and position of the electrically conductive links in the secondary coil determine the character-istics of the output voltage the characteristics of the out-put voltage are varied by shorting out at appropriate intervals along the length of the secondary coil a number of turns of the secondary coil, this being achieved by means of the links.

Abstract: ABSTRACT OF THE DISCLOSURE               APPARATUS FOR REMOVING PARTICULATE MATTER FROM AN ATMOSPHERE         A compact apparatus for removing harmful particulate contaminants from the air in a work space includes a nozzle for atomizing water.  The nozzle is connected to a supply of com-pressed air and to a supply of water, e.g., an ordinary water tap or storage tank.  The apparatus also includes a metal ring and a power supply coupled to the ring to charge atomized water inductively as the water is expelled from the nozzle.  A collar supports the ring in fixed, spaced-apart relation adjacent the nozzle.  The collar is constructed, at least in part, from a non-conductive plastic, such as nylon, to avoid shorting of the power supply.  Additionally, the collar includes a compressed air supply passage for introducing a stream of air into the collar.  This air flows past the nozzle and the ring to prevent accumulation of water on the ring and collar and the electrical shorting which may result therefrom.  Additionally, the stream of air minimizes degradation of the electrical charge on the fog of atomized water which would otherwise result from the addition thereto of oppositely charged water particles originating from the accumulation of water on the ring.

Abstract: ABSTRACT OF THE DISCLOSURE           A flashlight in accordance with the preferred em-bodiment of the invention includes a housing enclosing an insulating batter retaining member formed with spring arms for retaining a pair of batteries in spaced-apart relation-ship.  Further included is a light bulb having a pair of leads extending therefrom and carried at one end of the housing with leads each connected to a battery.  Adjacent the opposite end of the housing a conductive switch member is frictionally retained on the positive post of one battery and extends between the battery retaining member and a flexible wall of the housing.          The other end of the switch member is located adjacent a cutout portion of the battery retaining member which exposes a conductive surface of the other of the batteries so that when the flexible wall of the housing is pressed the other end of the switch wire contacts the other of the batteries completing a circuit between the batteries and the light bulb.  Stop members are formed on the battery retaining member and retain the batteries against axial movement.
