Corrugated sheets B, Fig. 3, cut from a web are delivered from a rapid conveyer to a slower conveyer 20 comprising belts 25a, 25b on which they are advanced in overlapping formation beneath hold-down rollers 59 mounted on a carriage 38 positioned so that each sheet is engaged by the rollers 59 before being released by the rapid conveyer, the carriage being settable along the conveyer 20 by a motor 53 according to the length of the sheets to be dealt .with. The sheets then pass on to a conveyer 83, Figs. 1, 6 and 8, beneath a gate 104, the conveyer 83 being driven by-the roller 24 of the conveyer 20, but at a minimum speed determined by a second drive from a further motor. The sheets then pass under hold-down rollers 59<SP>11</SP> on to a takeoff unit comprising rollers 186 to form a stack thereon, being urged down by suction applied through slots 158 in a plate 157. When a desired number of sheets is in the stack, as detected by a photo-electric cell at the inlet end of the conveyer 20, the gate is lowered by gravity and the rollers 186 are rotated to remove the stack from the take-off unit, a further photoelectric cell detecting this movement and resetting the apparatus, i.e. resetting the counter and raising the gate by chains 143 attached to a shaft 131 rotated by an air-piston.

In Fig.1, the free piston 3 comprises a replaceable, cylinder 30 clamped between two ends 28, 29 by an axial bolt 27. The cylinder carries the test pieces, piston rings 32. The ends 28, 29, slide in guide sleeves 6, 7 whilst the piston rings 32 slide in replaceable cylinder 2 which has a fluid jacket 33 for temperature regulation. At the ends of its oscillating travel, the free piston strikes pistons 10, 11 which are resiliently biased by gas cushions 20, 21. These pistons may also carry piston rings under test 65, Fig.4 (not shown). To test gaskets 50, Fig.3, (not shown) one of the gas cushions is replaced by a constant volume hydraulic "cushion" lying between the upper piston (53) and a shaped cover (52) the gasket lying between the housing (51) and the cover and around the hydraulic cushion so that impacts are transmitted to the gasket. The piston is moved by applying gas under pressure alternately above and below the piston; alternatively it may be oscillated electrically. The apparatus may be used as a vibration generator for transmitting vibrations through suitable coupling means to an external test piece such as a cylinder block.

A severing mechanism for a micro-film reader printer, having means for feeding print material M, Fig. 2, over an exposure platen 12, comprises cutter blades 23, 25 the blade 23 being secured to the printer housing 11, Fig. 1, so as to be arranged diagonally of the material and the blade 25 being secured across the open end of a U-shaped metal frame 27 so that the cutting edge of the blade 25 partially overlaps the cutting edge of the blade 23 in point contact therewith, the other end of the frame being mounted at its mid-point on a plate 29 secured to the housing 11, means being provided for flexing the frame 27 in a direction perpendicular to the frame so as to move the cutting edge of the blade 25 in travelling point contact across the cutting edge of the blade 23 to sever the material, the resiliency of the frame automatically returning the blade 25 to its original position upon release of the frame by the flexing means. The frame has secured thereto at 21 slotted brackets 19 attached to plates 16 secured to a frame 15 in which a mirror 14 is mounted, the frame 15 being rotatable about a shaft 17. Bracket 19 is fixed lower on the plate 16 at one side of the housing 11 than on the plate at the other side. Rotational movement of the mirror counterclockwise raises the frame 27 and the blades 23, 24 to sever from the supply the length of material resting on the platen 12. The blades are interchangeable and reversible. A guide 33 is attached to the frame 27 by legs 35, 37 and forms an opening through which the material passes whence it is fed between the blades 23, 25 the arrangement being such that after the severing operation and as the blade 25 is being lowered out of overlapping relation from the blade 23, the guide 33 returns the leading edge of the material from the supply roll back into the original path for subsequent feeding under the blade 23 and on to the platen 12. The guide 33 is provided with extensions 39, 41 which restrain lateral motion of the frame 27 by acting against the respective extensions 43, 45 of a light baffle 47 attached to the blade 23. The frame 27 is provided with an extension 49 to cover the opening between the platen and the blades which exists at the completion of the severing operation.
