摘要:
This invention is concerned with a golf club swinging apparatus for testing performance of golf clubs, for example. The golf club swinging apparatus is capable of swinging a golf club from an addressing position through take-back, back swing top, down swing, impact and follow-through positions to a follow-through end position, which results in substantially the same club swinging locus as by a golfer. The club swinging apparatus therefore enables flight distance and various other tests to be conducted reliably.

A novelty statue includes a figure that is adapted to move in response to a noise or in response to a sensed temperature. The figure is in the shape of either a human eye which blinks or in the shape of a letter I which moves into and out of a base.
摘要:
A system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process.
摘要:
An improved method of forming three-dimensional objects comprises irradiating an uncured photopolymer by transmitting an effective amount of photopolymer solidifying radiation through a radiation transmittent material which is in contact with the uncured photopolymer. The transmittent material is a material which leaves the irradiated surface capable of further cross-linking so that when a subsequent layer is formed it will adhere thereto. Using this method multilayer objects can be made.

A garment for wear by those interested in experiencing the physical effects of full term pregnancy. A fluid filled, weighted body of several pounds overlies the wearer's stomach while a rib belt exerts a compressive force to alter lung capacity. A bladder pillow simulates the effect of a fetus on the bladder. Garment straps permit garment fitting to a wide range of physiques while weights may be added to weight the garment to the size and build of the wearer for a true simulation.
摘要:
A device for rapidly demonstrating the darkening action of phototropic objects, particularly eyeglasses. The device has a housing or casing provided in its lower part (6) with a hollow space (7) which is placed over the objects to be demonstrated (8, 9) while such objects lie on any suitable horizontal supporting surface such as a table or desk. These objects are uniformly illuminated by a flash tube emitting light in the UV-A range and in the visible range. Upon each actuation of the circuit controlling the flash tube a plurality of flashes which succeed each other at a predetermined time interval is automatically given off.

Scheme and knowledge trainer apparatus for teaching trainees sortation scheme and knowledge items and skill for sorting such as mail sorting and the like, comprising an electronic sortation training console having a switch panel depicting plural horizontal rows and vertical columns of sort blocks symbolizing discrete sort locations each having a touch sensing switch and changeable indicia strips for providing the sort blocks with legends denoting sort location titles therefor. A visual projector is provided for receiving a training film having frames for successively displaying lesson information on a viewing screen depicting sort location legends correlated with the legends on the console blocks and having apparatus for producing correct location signals denoting the correct console sort block location for the displayed legends. Electronic circuits are coupled to the switches and respond to activation of the switches and to the correct location signals for sensing correct and error sorts upon activation of the touch sensing switches and providing continuous counts thereof on correct and incorrect readout counters. Light indication of the correct sort block may be produced responsive to each activation of a switch at a wrong sort location.

The invention is directed primarily to a display device for floor tile. The display device mounts on the top of a carton of floor tile with one floor tile positioned within the display device. The display device also has a provision for a photo showing the particular tile product in use in a room display scene.
摘要:
A method and apparatus for evaluating coins on an objective basis. A support structure displays facsimile coins representative of the obverse and reverse sides of a given class of coins. The facsimile coins within the obverse and reverse groups are further divided into sets. Each set contains facsimile coins representative of a particular type of coin defect or imperfection. The facsimile coins within a set are arranged according to increasing or decreasing extents to which the coin defect is exhibited. Each of the facsimile coins has assigned to it a number representative of the relative value of the facsimile coin in regard to that particular coin defect. The obverse and reverse sides of a test coin are compared with the facsimile coins within each set. The numeric values of the facsimile coins which exhibit the coin defects to the same extent as the test coin are noted and summed to arrive at a total numeric value for the coin. The monetary value of the test coin is then determined by a table which correlates the total numeric value of the test coin with its monetary value.
摘要:
A construction type educational and amusement device having as its basic element a generally spherical hollow module or capsule and adjuncts which may be interconnected and operatively assembled into a large number of different relations to form power-driven vehicles, cranes, propeller-driven floats, air propelled devices and many other assemblies of scientific interest. The capsules of a complete assembly may contain, respectively, an electric motor, gearing of various kinds and types, to form operative simulations. The modules are preferably of clear plastic so that operation may be observed and understood.
