Abstract: ABSTRACT    A can body whose bottom wall is coaxially formed with a ring of individually outwardly convex dimples or feet whose bottom wall is otherwise flat, centrally domed outward or inward, or otherwise formed, provided that after canning is completed, of all the can bottom portions the feet pro-trude furthest outwards to support the can.  In the pre-ferred embodiment, the bottom is initially domed inwards and a ring at the outer perimeter of the can bottom pro-trudes furthest outwards.  Then, after filling and closing, as the can contents are internally pressurized, e.g. during beer pasteurization, the central dome pops outwards pro-jecting the feet outwards beyond the perimetrical ring. e body of the can actually grows during pressurization to provide a can of sufficient volume and strength.  The overall result of the feet and bottom configuration is to provide a can of thinner material which meets the structural requirements previously met by a convention can manufactured of thicker material.

Granted: 1978-11-07
Abstract: ABSTRACT OF THE DISCLOSURE           Amplitude varying signal is time sampled at constant clock rate (E.G. 40 kHz for voice) and sample is compared (in encoder) with analogue conversion of digitally stored previous value.  If signal has increased, logical "1" is transmitted, if it has decreased, logical "0" is transmitted;  simultaneously digitally stored value is increased for "1", decreased for "0", by increment stored in companding counter.  To make increment match signal change between successive samples, companding counter content is increased by unity for three successive "1" or "0" signals, and decreased by six successive alternating "1" and "0" signals.  Decoder logic is same as encoder except that no comparator is used, encoded signals operating directly upon digital stores; analogue conversion of digitally stored value is output.

Abstract: A PROCEDURE FOR TIGHTENING TAPE WRAPS                       ON A SPINDLE                         Abstract In a rotating head magnetic tape transport, magnetic media is transported from a supply spool to a take-up spool.          Interlayer slippage, due to air entrapped between tape layers, is reduced by impressing a waveform on the take-up spool motor voltage during high speed search.  The impressed waveform has a high acceleration component.  As a result of the impressed waveform, a continual jerking action is imparted to the tape to squeeze out entrapped air and leave said tape in a state of tension or tightly wound.

Abstract: AUTOMATIC VISUAL TEACHING DEVICE FOR THE LEARNING    OF MUSIC OR COMPONENT PARTS THEREOF              Abstract of the Disclosure An automatic visual music teaching device for displaying the structure of coded chords.  The device com-prises a plurality of actuable switches for selecting a desired coded chord.  Signals associated with the actuated switches are temporarily stored and are indicative of the desired coded chord to be visually displayed.  A further switch is activated to transfer the stored signals indicative of the desired coded chord to a decoding circuit.          The decoded circuit feeds a memory system to select in a matrix the composite parts of the desired coded chord in accordance with a coded data signal sent to it by the decoder whereby the composite parts of the desired coded chord are visually indicated on a visual display element.          The method of visually teaching the component part structure of musical coded chords comprises simply the step of selecting switches having coded marking thereon representa-tive of musical notes in major and minor tones and corres-ponding to a desired coded chord for transferring a corresponding signal to a temporary storage circuit.  A transfer switch is then depressed to obtain the visual indication of the composite parts of the desired coded chord for learning purposes.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure describes a method of processing waste water using an adsorbent which can be regenerated, such as ac-tivated carbon or aluminum oxide.  For this purpose, treated waste water is conveyed through an adsorber filled with an ad-sorbent having a desired given nominal particle size in order to charge the adsorbent. The charged adsorbent is then moved from the adsorber and waste water is drained from the discharged absorber.  The adsorbent is conveyed through a measuring device into a regenerating device such as a fluidized bed oven to be regenerated, after which the regenerated ad-sorbent is pumped into the absorber.  Before the charged ad-sorbent enters the regenerating device, the adsorbent is separated into a first adsorbent fraction including adsorbent particles having the above given nominal size and into an un-dersized second adsorbent fraction consisting of adsorbent par-ticles having a size less than the given nominal particle size but a particle size which is greater than 10% of the given nominal particle size.  The  undersized second fraction is processed in a processing plant until it reaches the nominal particle size and is then returned to the adsorber together with the regenerated adsorbent particles.  This method is particularly applicable to the removal of phenol from waste water.
