Title: Safety structure esp. for once only impacts - comprises alternate layers of reinforced concrete and highly damping material
IPC: E04H9/00
Filed: 1980-07-03
Abstract: Structure, esp. of plate form, is for withstanding impulse or impact loads up to the limit of its resistance. The plate is composed of two or more layers, a layer of reinforced concrete alternating with a layer of material possessing high damping properties for the vibration waves induced by the impulse. The layers possessing high damping properties may contain fibre reinforcement embedded in a matrix, esp. a cement matrix. The fibres may be partly bonded to the matrix. The layer pref. contains porous cavities to assist the damping properties, more specifically cavities produced by the presence of polystyrene beads, gas-generating additives etc. The plate structure is designed particularly for military or civilian purposes where a once only max. loading is expected, e.g. from a crashing aircraft. The propagation of the vibrations is reduced to a min. and consequently widespread cracking does not occur even at high loads approaching failure.

Title: Anti-wheel-lock braking system for tracked vehicle - reduces stopping distance by varying braking pressure according to wheel speed and deceleration
Inventor: ROIDER WILLIBALD DIPL ING
IPC: B60T8/70
Filed: 1980-10-20
Abstract: A tachometer is coupled to the wheel being monitored and produces a signal describing wheel speed. A reference generator produces a reference signal describing the speed of the vehicle. A differentiator produces a signal proportional to wheel acceleration or deceleration. A comparator circuit compares the wheel acceleration signals, the wheel speed signals and/or the difference signals between wheel speed signals and reference signals with given thresholds. An evaluator reduces the braking pressure, maintains it constant or increases it depending on the output signals from the comparator circuit. The reduction or increase in the braking pressure is either fast or stepped (slow) depending on the output signals from the comparator circuit. In a start phase at the beginning of braking the braking pressure is maintained constant when a first negative acceleration threshold is fallen below. The braking pressure is increased when the first negative acceleration threshold is again exceeded. The start phase is ended when the wheel acceleration falls below a second larger negative threshold. The braking pressure is then rapidly reduced.

Title: Measuring calorific energy expended in pedal drive - deriving deformation of pedal arm and using summation of measurements obtained during each rotation
Inventor: MUELLER HUBERT PROF DR ING
IPC: A63B24/00
Filed: 1980-12-05
Abstract: A method and arrangement for measuring the energy consumed by a piece of equipment with a foot pedal drive enables the user to be informed simply and directly of energy expended or calories consumed throughout the period of use. The energy expended per revolution of the pedal drive is measured. The measured energy values are summed during the period of use and the total displayed, pref. in calories. The energy value is only measured at the position of the pedal drive at which the largest torque acts in the forward direction of the drive. The energy values are obtained by measuring the deformation of an arm (10) of the pedal drive which is proportional to the pedalling force. The total value displays can be manually cleared.
