Abstract: ABSTRACT OF THE DISCLOSURE An open-topped box of rectangular horizontal outline, with vertical side and rear walls. has a forwardly slanting front wall terminating at about half the height of the  box in a for-wardly and downwardly bent handgrip. The handgrip merges at its ends into inner boundaries of two hollow upstanding corner pro-files which flank the access opening left above the front wall and have shoulders rising from the bottom to the top of that opening, the lower portions of these shoulders being aligned with two more forwardly positioned ribs of the cornerprofiles defining with those lower portions a pair of vertical guide grooves for a closure plate insertable from above even when the box is overlain by a similar box to form a stack. The closure plate may  be a hinged dust cover of L-profile whose short horizontal leg, resting on the handgrip, projects forward and ends in a pair of gudgeons abutting two webs of lesser height than the ribs also projecting upper edge with lateral wings which are the only parts received to let the dust cover pivot forward about its gudgeons into a depending position unblocking the access opening.

Abstract: ABSTRACT OF THE DISCLOSURE           A vulcanizing press for vulcanizing flat articles having locking pawls for locking the pressing plates of the press at a certain distance from each other in the closed vulcanizing position of the press.  By letting one of the pressing plates be without heating elements and carry an in-flatable member, such as a membrane, inflated by a pressure fluid, which membrane in the closed position of the press is positioned and adapted to supply a uniform pressure substan-tially over the whole flat side of the vulcanizing article positioned between the pressing plates an even surface pres-sure is obtained all over the textile side of the vulcanizing article substantially independent of the thickness of the article and without use of toggle mechanisms or high power hydraulic cylinders.  When the inflatable member is placed on the downwardly facing side of the upper pressing plate the articles can be conveyed into the press on a conveyor belt, the path of which is stationary relative to the press frame, but if the inflatable member is placed on the upwardly fac-ing side of a lower pressing plate without heating elements the difference of the temperature between the upwardly turned side of the articles and the downwardly facing side of the upper pressing plate can be increased whereby the last men-tioned article textile side can be made of a less temperature resistant material.

Abstract: ABSTRACT    A tone generation system intended primarily for use in electronic musical instruments wherein a digital representation of a harmonically rich waveform is sampled, and a musical tone is produced therefrom.  The stored waveform could be the four-term Blackman-Harris window function, which has negligible sidelobes and thus greatly attenuated higher harmonics. The stored function is read out at a fixed rate, but the time periods between successive readings of the waveform are varied to thereby vary the frequency of the output signal.  Harmonic content is varied by adjusting the amplitudes of successive wave-forms in the waveform train, which has the resultant effect of producing harmonics of selectable amplitudes.

Abstract: ABSTRACT OF THE DISCLOSURE                 A core clamp mechanism serves to grip a core on a winder shaft by means of a plurality of ring elements and an expandable elastomer tube.  A spacer sleeve abuts at one end with the free end of the core and receives, at its other and, a locking disc in preformed engagement spaces which cooperate with lugs formed on the disc.  The elastomer tube is positioned upstream of the disc and supplied with air pressure for expansion of the tube against the disc which serves to compress the sleeve against the core. Shrinkage and other adjustments during the clamping operation automatically accommodated by axial expansion of the tube under pressure. To remove a wound core, pressure is released through a valve from the tube and the disc moved clear from engagement with the sleeve.  Cut outs corresponding to the disc lugs are formed on the sleeve so that, by aligning the cut outs with the disc lugs, the sleeve can be pulled off the shaft and the core removed and replaced.

Abstract: Abstract Metal Detection Apparatus Metal detection apparatus includes an oscillator coil 102 driven by an oscillator 101, which induces in detector coils 103, 104 equal and opposite E.M.F.s such that a nominally zero output is produced at terminals D.E. When metal is detected the E.M.F.s in coils 103, 104 move out balance to produce a voltage at D.E., which is detected by circuit IC11 and fed to output circuits 111.  Drifts in the nominally zero output at D.E. are corrected by com-bining quadraphase balancing signals on lines 109, 110 with the detector coil output by means of amplifier IC10. The combined signal from IC10 is fed to phase sensitive detectors IC1, IC2 which respectively detect the quadraphase components of the combined signal from IC10.  The outputs of IC1, IC2 are stored by capacitor circuits 112, 113 and used to adjust variable capacity diode bridges 106, 107 which adjust the amplitude of the balancing signals to maintain a nominally zero output from IC10 when metal is not being detected.  The capacitor circuits 112, 113 have a long time constant so that the balancing signals are not adjusted to cancel out the detection of metal, but circuits IC5, IC6, IC13 switches the stores 112, 113 to provide a shorter time constant after metal has been detected in order to restore the circuit rapidly to a balanced condition. Additionally, the circuits IC5, IC6, IC13 disconnect the capacitor circuits from the phase sensitive detectors IC1, IC2 for a given time when metal is detected so as to restore the circuit rapidly to a balanced condition after detection of the metal.

Abstract: ABSTRACT OF INVENTION      The invention relates to existing band saws powered by elec-trical motors.  Prior arts of band saws are commonly designed with two wheels as support and glide path for band saws blades.  They were commonly revealed through patent search such as: #2, 711, 195 inventor John A. Hill; patent #3, 480, 051 inventor Charles E. Gray; patent #3, 902, 391 inventor Harold Bond; patent #3, 908, 501 inventor Tsuneo Aizawa; and patent #4, 128, 031 inventor Masso Sato.     My invention incorporates four wheels to form the saw blade glide or travel path.     Therefore, the primary object of my invention, having four wheels, eliminates the large bulky wheels used for achieving height and depth   Depth being the distance  between the blade and frame. Height being the distance between the working surface area and the bottom portion of the guard.     Prior arts have 2-24" wheels on the large models to achieve a 22" width of cut.  Being such a large wheel, it has to be con-structed of heavy and warp free material.  It also has to be per-fectly balanced to achieve smooth operation and requires larger bearings.  To turn all these heavy metal wheels leads to more pow-er input.  Normally a band saw of this size will take 2 to 5 HP electric motor, thus, overall height and weight of saw is gross. To achieve height of cut at 12", this type of saw needs two wheels of 24", which equals 48" plus the 12" height of the cut plus the guard and base stand.  Overall height of the saw would be approx-imately 8" tall and weighing in at 1000 lb.     It is another primary object of present saw to reduce height, weight, bulk, and power consumed.  It can also be used as wall mounted or on a fixed or mobile stand that could incorporate brake leaded casters, thus making it a more compact and lighter, yet achieving same cutting depth or clearance being as stated.     My invention can be made much cheaper and novel for consumers, present saw having smaller wheel circumference delivers more torque power to the band saw blade when using 1/5 of power source that the prior arts use and also reducing the speed of band saw blade travel. Natural accuracy due to smaller circumference of wheels.     It is another object of my present saw to also reduce friction, vibration, and high speed flexing of blade.  Therefore, extending life of said blade, and almost entirely eliminating high speed noise frequencies, thus lowering the harmful noise syllables as noted in prior arts patent #4, 128, 031 inventor Masso Sato.
