Abstract: APPARATUS AND METHOD FOR COMBUSTION          Abstract of the Disclosure A method and apparatus for the controlled combustion of combustible materials is disclosed whereby the combustion is confined within a slot defined by a plurality of combustible logs in longitudinal contact and opening toward the objects to be heated.          Background of the Invention This invention relates to methods and apparatus for achieving controlled combustion of combustible materials, and more particularly, to an apparatus and methods of directing thermal radiation produced by such controlled combustion.    One problem which arises from the use of known apparatus and methods for burning combustible materials, such as domestic fireplace grates for combustion of wooden logs, is that a substantial fraction of the radiant heat from the combustion of such logs is directed toward the walls of the fireplace in which the grate is positioned.  Therefore, the use of this type of apparatus and its method for combustion is highly inefficient.  Examples in the prior art which show grates which burn logs in this manner are U. S. Patent No. 3,670,714 to Eyges (1972), Patent No. 3,505,986 to Wood (1970), Patent No. 2,985,165 to Peterson, et al (1961), Patent No. 2,585,523 to Wellman (1952), Patent No. 1,418,411 to Ward (1922), Patent No. 780,800 to Keferstein (1905), and Patent No. 2,057,659 to Daniel (1936). The need for achieving optimum use of chemical energy stored in natural fuels by combustion is recognized as a contemporary problem.

Abstract: Abstract of the Disclosure An automatic binding device or binder for binding a long material such as a bundle of electric wires with a lace by actuating the mechanisms associated therewith according to pilot signals produced when the lace passes through the mechanisms.  In this respect, a lace used should afford given rigidity and flexibility.  This binder includes a guide member which may be opened and closed, and is formed with guide channels running along its inner peripheral surface for guiding a lace for use in binding.  The guide member is formed with a lead-in hole for a lace on one side and a lead-out hole on the opposite side.  For smooth guiding of a lace through guide channels, there is used a reversibly rotatable roller mechanism or a combination of the roller mechanism with a vibrating mechanism for vibrating a lace being guided through the guide channels.  The lace paid out through the lead-out hole from the guide member is gripped by a lace gripping mechanism on the tip portion of the lace. According to a signal produced in association with the movement of the lace gripping end portion thereof, the primary tightening operation due to the reverse rotation of the roller mechanism is effected, followed by the second-ary tightening operation due to the movement of the lace gripping mechanism. Thereafter, the lace is cut in the opposite portions of a knot or a bound portion thereof by means of cutters, and then waste lace thus cut off or chip is removed by suitable means

Abstract: TRACTION-DRIVE TRANSMISSION     ABSTRACT OF THE DISCLOSURE     The invention contemplates an improved mechanical traction drive providing a single control whereby a desired range of speed ratios between input and output shafts is selectively available, without requiring clutch connection to the power source, such as an internal-combustion engine.  The transmission involves a combination of completely mechanical friction-roller and meshing-gear planetary systems which are connected at all times, whether the single control is operated to call for a forward drive, a stop or a reverse drive of the output shaft.  For the particular disclosed form, provision is made for automatic downshifting reaction to increasing load, and major axial-reaction forces are self-contained by rotating mechanism, thus (a) avoiding substantial axial force components on main-bearings of the mechanism, and (b) reducing to very small magnitudes the requisite force for selective control actuation.

Abstract: ABSTRACT            AIR FILM SUPPORTED AND GUIDED LOAD SUPPORT MEMBER     A fluid levitated generally convex support member partic-ularly useful in supporting a pallet, plate or belt such that the pallet, plate or belt load may be moved in an air powered track system, the system including at least one concave track with means for supporting and guiding the convex member and the pallet, plate or belt thereabove on a thin film of pressurized air jetting from nozzles in the track.  The support member includes a generally tu-bular, flexible and partly deformable outer member and means for internally stressing the outer member so that under load there will be controlled deformation thereof.  The deformed member will be closely complementary to the track surface to maximize load carrying capacity while minimizing fluid support power requirements and the detrimental effect of track deformities.  Of particular significance is the ability of the support assembly covering to vibrate at high frequency at the track surface in response to the track jets and the wedge flow of the fluid support film to provide a pumping action which propagates and augments the pressure of the support film.          Also, the small air film provides a controlled air gap which permits the use of electromagnetic propulsion means installed as part of the track for reaction with suitable secondary devices included in the support means.  Under load removal there will be controlled recovery of the shape of the outer member.  The support member ex-hibits excellent wear, cleanliness, cushioning, manufacturing, ant select frequency response and damping characteristics.
