Title: Trolley for facilitating movement and or laying of paving slabs or flags
Inventor: JONES GEORGE HENRY
IPC: E01C19/52
Filed: 1986-01-15
Abstract: A trolley comprising parallel levers 20 pivotally mounted on wheeled axle 12 and manoeuvrable by means of handles 24. An abutment plate 32 extends transversely between the front ends of the levers 20, and arm 42 of beam 40, pivotally mounted on the axle 12, carries an angled thrust plate 44 substantially parallel to the abutment plate. When the beam swings anticlockwise about the axle 12, the spacing of the thrust plate 44 from the abutment plate 32 diminishes. Thus, when the device is offered to a slab 10 and downward pressure is applied to the handles 24, the slab 10 will be picked up, the weight of the slab 10 serving to increase the grip on itself. When lowered the slab 10 can be released by pressure applied to the beam by means of pedal 54.   <IMAGE>

Title: Testing electrical circuitry or components
Inventor: CORKAN JOHN
IPC: G01R19/165
Filed: 1986-04-24
Abstract: A device 8 measures a property such as the resistance of a circuit 1,2, e.g. an alarm, and a value near to the measured property is then set in a memory 11. A comparator 13 then continuously checks the reading on the measuring means 8 with the value set in memory 11, and if the reading on measuring means 8 equals, or exceeds, the value in memory 11, a warning 12 is registered. The comparator 13 may be set to react to readings less than that in memory 11. In another arrangement (Fig. 2, not shown), a regular flow of pulses is passed though the circuit/component and a pulse detector reacts to any interruption in the flow of pulses. <IMAGE>
