“A sphygmomanometer having cuff means comprising an inflatable cuff having a length susceptible to inflation.  The cuff means includes fastening means preferably comprising first and second mutually interchangeable parts spaced apart longitudinally on the cuff when the latter is inflated, one of said parts being attached to the cuff by means permitting the fastened cuff, in use, to adopt a frustro-conical form so that it can accommodate the taper of a subject’s limb.”

“A device for producing a stream of aerated water, the device having a first opening for producing a first jet of water and a second opening for producing a second jet of water directed into the first jet of water so as to form a single turbulent stream of water in which air is entrained.  The device being constructed by forming two relatively angled surfaces on at least one component, the surfaces having respective aligned grooves, forming two oppositely angled surfaces on at least one other component and mounting the two relatively angled surfaces against the two oppositely angled surfaces such that the grooves, together with the oppositely angled surfaces define passages for the formation of jets of water.”

“There is described a horticultural feeding device (1) comprising a hopper (2) provided with a first aperture (8) in its base and a feed tray (9) positioned adjacent the first aperture (8) and provided with a second aperture (10) characterised in that the hopper (2) is provided with means for vibrating the feed tray (9), and a method of treating e.g. lawns using the aforementioned device.”

"A triggered barrier system comprises a plurality of self contained units, each incorporating a static pressure change sensor which releases a spring to cause a piston forceably to eject particulate suppressant material from an hermetically sealed chamber."

"A mop comprises an elongate handle, a tubular hand grippabe sleeve slidably mounted to the lower end of the sleeve for rotation about an axis at an angle of about 40 degrees to the longitudinal axis of the handle.  The cleaning head is provided on its underside with a cleaning pad having a substantially flat cleaning surface which lies in a plane normal to the axis of rotation of the cleaning head.  In use, the cleaning head is arranged with its longitudinal axis lying perpendicular to the to-and-fro movement of the mop.  However, in order to clean in confined spaces, the cleaning head can be rotated through 90 degrees, so that its longitudinal axis now extends in line with the normal direction of movement."

"A releasable ratchet mechanism having single handed operation comprising a rotatable input member, a rotatable output member and mutually engageable ratchet means, effecting selective coupling between the input and output members.  Rotation of the input member in a first direction rotates the output member in that direction but prevents rotation of the output member in a second, opposite direction.  Rotation of the input member in the opposite second direction permits rotation of the output member in that second direction."
