Title: Energy Absorbing Device
IPC: B62D39/00
Filed: 1967-06-19
Abstract: 1,195,435. Buffers for lifts. ARA Inc. 19 June, 1967 [17 June, 1966], No. 28141/67. Heading B8L. [Also in Divisions B7, E1 and F2] A shock absorber converts the mechanical energy of a moving body into cyclic plastic deformation of a deformable element in the following manner: unidirectional movement of e.g. an impact receiving member causes portions of the element to be stressed beyond their elastic limit first in one direction (e.g. in tension) and then in the other (compression) so that each such portion undergoes repeated stress cycles in each of which the stress-strain plot incorporates a hysteresis loop. The invention requires that as the unidirectional movement continues, different portions of the deformed element come successively into operation. The shock absorber of Fig. 7 consists of an inner rigid tube 18 and an outer rigid tube 12 between which is located a metal helix 74 the turns 76 of which are frictionally gripped between the tubes. When the tubes move axially relative to each other each turn 76 engaged by them is deformed by rotation about its own internal axis, each circumferential filament of each turn of the helix being at one instant radially outside the internal axis and stressed in tension and at a later instant radially inside it and stressed in compression. Both tubes taper slightly, so that the number of turns engaged between them varies with stroking distance. In Fig. 24 (not shown, but see Division F2), neither tube tapers, but one of them has longitudinal recesses and a spacer (20b) between a first helical coil (74b) at least part of which occupies an unrecessed portion and a second coil (74c) in a recessed portion. This arrangement allows for the onset of plastic deformation to be controlled by suitable choice of the length of the spacer (20b). Application to lifts.-A buffer 10e, Fig. 29, for a freely-falling lift car consists of two shock absorbers of the Fig. 7 form connected in series and attached to the base 16e of the car.

Filed: 1934-10-02
Abstract: 442,305. Fastening railway vehicle doors. PARKER, T. G. K., 86, Leigh Road, Leigh-on-Sea. Oct. 2, 1934, No. 28205. [Class 44] For automatically locking and unlocking a railway-carriage door a bolt 1 is released and retracted respectively by the alternate-energization of two electromagnets 12, 6 controlled by a speedometer 9 having two contact making positions 13, 8 corresponding to the speeds at which it is desired to lock and unlock the door. In addition a switch 16 enables the guard or driver to lock or unlock the doors of a train irrespective of the speed, and the guard may lock or unlock individual doors by means of a key which directly moves the armatures of the electromagnets. Key-operated cams also may be provided to act on the bell cranks to isolate individual locks so that they can only be opened by the guard. The electromagnet 6 acts on an armature 5<b> having an arm 5<a> coacting with a pin 4 on the bolt 1 to retract the bolt against a spring 2 until a notch 11 in the bolt engages a detent 10<a>. The detent 10<a> is tripped by an armature 10<b> acted upon by the electromagnet 12. A switch 14 breaks the circuit of the electromagnet 12 as soon as the bolt is shot.

The stirrup may be of light metal or plastics and the base plate and arms may be secured together by screws or rivets or by welding. The pins 3 may be screwed or rivetted to the arms 4. In case of breakage of a test-tube during centrifuging, the beaker 5 serves to receive the contents of the test-tube and its broken parts. The beaker may be made of transparent plastics and is provided in its opposite side walls 8, 9 with grooves 10 which receive the stirrup arms 4 so as to prevent dislodgment of the beaker. The holder 6 may be made of light plastics and is formed in its upper part 13 with holes 14, Figure 2, for receiving the test-tubes 15 which rest at their lower ends on a pad 16 loosely placed on the bottom 12 of the holder. In a modification, Figure 10, the arms 28 of the stirrup carry an upper frame 30 and the stirrup may be dismensioned to receive one or four beakers. Four test-tube holders may be mounted in a single beaker or one holder may be mounted in each of four beakers. The base plate may be provided with flanges 32 or other receiving parts such as pieces, bars or cams for positioning and holding the beaker or beakers. Alternatively, a trough, Figure 11 (not shown), may be secured by screws to the base plate. In Figure 12, the head 17, on which a testtube carrier is shown pivotally suspended, is mounted in a centrifuge drum 35 closed by a lid 36. A photo-converter 37 is mounted in the lid 36 and faces a stroboscopic lamp 38 which is mounted in the base of the drum and emits pulses or flashes of light at a frequency adapted to the speed of the centrifuge head and to the number of test-tube carriers. The photo-converter has two groups of photo-cells. One group 39 responds to bright-dark reflection and is disposed over the trajictory of the closed ends of the testtubes where sediment tends to accumulate. The other group 40 responds to dark-bright reflection and is disposed over the parts of the test-tubes where clear liquid is likely to occur. The responses of the two groups are combined by logic circuitry and switches to give a single control signal which is arranged to trigger the halting of the centrifuge when the sediment and clear liquid have separated out in the test-tubes.
