Title: Underlay fabric - for preventing a rug slipping on a carpet has anti-slip upper surface
IPC: B32B5/18
Filed: 1973-06-21
Abstract: An underlay fabric for locating between a rug and carpet to prevent the rug slipping includes a lower carpet contacting ply of air permeable flexible material (e.g. plastic foam) and a rug contacting upper ply (e.g. of synthetic rubber) having on its rug contacting face a series of ribs defining air channels between them and presenting an antislip surface. Pref. the ribs are sinuous and are provided in distinct square zones whereby the ribs in one zone are perpendicular to the ribs in an adjacent zone and pref. an intermediate ply of good electrically insulating material (e.g. woven cotton fabric) is provided between the upper and lower plies. Damage to the carpet pile and build up of static electricity is reduced.

Abstract: AMPLIFIER PROTECTION CIRCUIT                           ABSTRACT      A protection circuit for a transmitter amplifier is provided which senses the forward power level and develops a first voltage which is compared with a reference voltage to provide a control voltage which controls the power developed by the transmitter amplifier.  An increase in the forward power level is detected changing the control voltage to cause a reduction in the forward power developed by the transmitter amplifier.  A decrease in forward power level is detected changing the control voltage to cause an increase in forward power developed by the transmitter amplifier.          A forward power level below a predetermined level for a predetermined period of time is detected causing a reduction in the reference voltage.  Reduction of the reference voltage reduces the control voltage to reduce or terminate the forward power of the transmitter amplifier.  An excessive control voltage coupled to the transmitter amplifier is also detected increasing the first voltage which in turn causes a reduction in the control voltage thereby maintaining the control voltage below a preset level.

Abstract: A B S T R A C T           A method for treating a metal surface treating solution and a rins-ing liquid in the metal surface treatment process in described wherein a pro-cess solution is circulated in at least one water washing tank in the direc-tion opposite to the direction of advance of treated articles. The articles are successively transported to a surface treatment tank and a water washing tank.  Process solution is introduced into a concentration process connect-ed to the surface treatment tank to separate and recover effective ingredients of the surface treating solution from the process solution, by subjecting the process solution continuously to the concentration treatment. A washing water is supplied at a prescribed rate from a water source to a final water washing tank for washing surface-treated articles.  Toxic substances contain-ed in an exhaust gas generated in the surface treatment tank are collected and introduced into the concentration process to separate and recover effect-ive ingredients of the surface treating solution.  The total process is con= ducted in a completely closed system without discharging active ingredients of the surface treating solution and wash water outside the system.

Abstract: SHIFT AND ROTATE CIRCUIT FOR A DATA PROCESSOR     Abstract of the Disclosure A shift and rotate circuit is disclosed for a processor which receives 16-bit words as input data, which breaks down each received word into four 4-bit bytes, and which performs logical and arithmetic operations on each word on a byte-by-byte basis.  A word is shifted a speci-fied number of bit positions (1) by entering the word byte-by-byte in consecutive locations of a first 4-bit wide memory, (2) by entering the same word in an ordered byte sequence in a second 4-bit wide memory with the ordered sequence being determined by the number of bit positions the word is to be shifted, and (3) by concurrently applying the contents of both memories byte-by-byte to the shift and rotate circuit which shift the received information to the required number of bit positions and writes the shifted information into consecutive locations of the second memory.  The 4-bit bytes of the shifted word are ultimately reconstituted into a 16-bit word and outputted onto the I/O system.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a combination of a post and an end connector for use in a rack system to support shelves and the like.  The posts have first and second side ribs extending longitudinally and centre portions extend between the side ribs.  Each centre portion defines longitudinally spaced slots and the side ribs are dis-posed symmetrically to either side of the centre portions.          The end connector has a channel shape adapted to fit snugly over a side rib of one of the posts.  Coupling elements extend from the channel shape and each has a cantilever portion and a downward projection dependent from an end of the cantilever portion.  The projection defines a rearward face inclined downwardly and rearward-ly for engagement with a rearward side of the centre portion of the post after engaging the coupling element in the post.  Consequently a downward force on the end connector will result in a wedging action as the rear-ward faces of coupling elements ride on the centre por-tion thereby drawing the end connector into firm and snug engagement with the corresponding side rib of the post.

Abstract: ABSTRACT OF THE DISCLOSURE     A fuel supply apparatus generates hydrogen and oxygen by electrolysis and radiolysis of water.  The apparatus includes an electrolytic cell which has a cylindrical anode surrounded by a cathode.  The anode is fluted and the cathode is slotted to provide anode and cathode areas of substantially equal surface area. Oscillator and transformer circuitry produces high voltage pulses from a low voltage constant.  DC supply source and these pulses are applied to radiation generators which generate  short wave length electromagnetic radiation with which electrolyte within the cell is irradiated while current is passed between anode and cathode.      Hydrogen and oxygen are collected in chambers which are integral parts of the electrolytic cell and these gases are collected and mixed together.
