Abstract: ABSTRACT OF THE DISCLOSURE      The activity of cation-exchangeable layered clay or crystalline aluminosilicate catlayst in esterification, etherification, hydration, and cracking reactions is promoted by addition of a strong acid such as sulphuric acid, phosphoric acid, hydrochloric acid, hydrofluoric acid or para-toluene sulphonic acid.  The further addition of water to the reaction can extend the life of the clay catalyst and ill some cases its catalytic activity.

Abstract: ABSTRACT OF THE DISCLOSURE     A security transfer unit has a cashier's door and a customer's door for providing access to an intermediate transfer chamber from opposite sides of a security screen.  Only one of the doors can be opened to give access to the chamber  at a time, opening of the cashier's door being normally obstructed by a pivotted bar that is swung down across the door to engage a bracket. Swinging of the bar up to remove the obstruction turns a shaft to block, via a cam, withdrawal of catch-bolts which hold the customer's door closed.  The cam in this condition also abuts a block mounted on the rear edge of the door such that if the customer's door is open as the bar is swung up it will be forced closed before the cashier's door can be opened.

Abstract: A STEERING SYSTEM Abstract of the Disclosure A hydrostatic power steering system with constant volume feedback compensation including first and second steering cylinders.  Each cylinder has a housing containing a piston with an attached piston rod extending through one end of the housing.  The pistons and piston rods form a head chamber and two feedback chambers within each of the cylinders.  The outer ends of the piston rods are connected to a pair of steerable wheels and also to each other by a mechanical link which allows the piston rods to move simultaneously.  A control valve is also present which selectively controls the passage of a pressurized fluid from a supply source to a head chamber of either of the cylinders.  The cylinders, which have their feedback chambers fluidly connected together, are manually operated by a steering wheel which actuates a metering pump connected across the fluid passages.  As the steering wheel is turned, the fluid is transferred among the various chambers of the steering cylinders causing the piston rods to extend and retract, thereby turning the wheels.

Abstract: CYCLE TIMER            ABSTRACT OF THE DISCLOSURE         A cycle timer comprises an angle detector for converting mechanical angle information into electrical angle information.  A memory unit stores the timing information and a control program sets an output if the angle information falls within an "on" region of predetermined timing information and resets the output if the angle information falls within an "off" region of the predetermined timing information.          An arithmetic processing unit reads out from the memory unit a timing condition of the information that has been outputed from the angle detector, and a latch circuit is selectively set and reset one at a time in response to the output from the arithmetic processing unit.  The device has the advant-age that setting of initial coincidence between the timer and a machine being controlled thereby is simplified.

Abstract: ABSTRACT OF THE DISCLOSURE            A cleansing composition is disclosed that is particularly suited for compaction into tablet form, and comprises a phosphate salt, an optionally added silicate salt, such as a metasilicate and at least one perborate salt, wherein at least a portion of the perborate salt component is present as a compacted, gran-ulated mixture with from about 0.01% to about 0.70% by weight of the perborate salt, of a polymeric fluorocarbon.  Prefer-ably, the perborate salt includes sodium perborate monohydrate and anhydrous sodium perborate, and polytetrafluoroethylene comprises the polymeric fluorocarbon used to prepare the granules.            When present, the silicate salt is preferably utilized within a particle size ranging from about 1 to about 25 microns.          The silicate aids disintegration and assists in mechanical cleaning, when the composition is prepared in tablet form for use as a denture cleanser.            The use of the perborate granules reduces the difficulty of compacting the composition to form tablets, without impeding the operation and activity of the tablets as effervescent cleansers.

The scum is maintained within the tank in a quiescent and substantially nonagitated state for at least twelve hours, during which the combustible oils, greases, fats and the like are rendered separable from the other components of the scum.  The scum is then conveyed from the tank to a processing unit where the fats, oils, greases and the like are separated from the water and solid material remaining in the scum.

Abstract: ABSTRACT     A guide tube for guiding a wire of filler metal in an arc welding machine and optionally for applying current thereto.  The tube has a metal body with a longitudinal bore through which the wire passes.  Near the front of the tube there is play take up means in the form of two balls lodged in transverse passages through the tube wall.  The balls are urged into the bore by conical springs which can be compressed into the form of a spiral and therefore take up so little room as to enable a sheath to be fitted over the body.  An end piece projects from the front of the guide tube.  It is held in place by a rim of the sheath and both the sheath and the end piece are made of refractory material to protect the guide tube.  This helps to prevent the tuba becoming clogged in operation, since the splashes of molten metal do not adhere to the refractory material.

Abstract: The current transducer is of the type comprising a Rogowski coil extending around a first conducting element in which a current to be detected flows. The first conducting element is provided at one end with a first terminal connector. A second conducting element is mounted on the first one so as to cover and preferably embed the external periphery of the coil. The second conducting element is electrically connected to the first conducting element at the end thereof which is opposite to the one end provided with the first terminal connector. A second terminal connector is provided on the second conducting element on the same side of the plane of the coil as the first terminal connector. This arrangement forces the current flowing between the first and second terminal connectors via the first and second conducting elements to flow around the periphery of the coil and thus to shield the coil.
