Dynamic Trolleys  [105.59 PH]
300 mm long, metal reinforced at ends, having three low-loss bush bearing PVC wheels and fitted with spring-loaded impulse rod. Rod has three positions to provide different impulses and is triggered by a release pin. With removable metal pins at each end to enable trolleys or masses to be stacked or to provide anchoring points for accelerating cords.
Trolley Runway  [105.60 PH]
This is designed to provide a smooth flat easily inclinable surface for dynamics experiments using trolleys. Wrap Resistant wood board, 2450 x 300 x 20 mm thick, reinforced with metal angle side rails. Complete with six feet for levelling or inclining the runway, two fixed centrally and two at each end adjustable for height.
Ticker Tape Timer - A.C.  [105.61 PH]
Operates on 12V A.C. The timer employes electromagnet, with spring loaded armature which vibrates above a support table for a carbon paper disc. Paper tape, drawn through guides on the table, is struck by a dotting screw carried on the armature. Additional with extra guides accommodate 4.5 mm external diameter rubber tubing for the 'Pearls in air' water drop experiment. The peg on the support table is movable to allow maximum use of carbon paper discs. Supplied with 90m roll of tape and carbon paper discs. The ticker tape Timer produces dots spaced at 1/50 or 1/60s intervals depending on main frequency.
Ticker Tape Timer - D.C.  [105.62 PH]

As similar to 52, but operates on 12V D.C. Produces dots at 1/50s intervals only.

Spare Parts :  
  a) Ticker tape, width 9.5mm, in rolls approx. 300meter long.
  b) Carbon paper Discs. Pack of 100.
Elastic Cord with Eyelets  [105.63 PH]

For accelerating dynamic trolleys. With a length of elastic cords wit brass eyelet at each end. In use cord is attached with the trolley by slipping one of the eye lets over the front dowel peg. (One or more cords may be used simultaneously depending upon the acceleration required.) Constant acceleration will arise if the cord is stretched a constant amount, say, to length of the trolley. The Cords are packed in tens mounted on a card for easy storage.

Dimensions : 150 mm unstretched length between eyelets.
Flectcher's Trolley  [105.64 PH]
