The machine then draws alongside a trailer, and an arm (4) seizes the top basket by means of two jaws (5) and places it on the trailer. The jaws open, releasing the basket, and then return to pick up the next basket which has been raised to the correct position by the fork. The arm (4) may pick up baskets and place them in the cage.
Patent FR-2240130-A1 (FR)
Title: Vibration damper for master brake cylinder - having damper piston spaced from master brake piston by spring
IPC: B60T11/22
Filed: 1974-05-31
Abstract: The front end of the master brake piston is fitted with a damper piston spaced from it by a coil spring which also serves to return the master brake piston to its null position after braking. The damper piston is spaced from the end of the piston bore by a cup spring and a fluid cushion via a restricted return duct to the reservoir. The system reduces the brake vibrations resulting from uneven braking surfaces. These vibrations often lead to steering vibration. For dual braking systems each piston is fitted with a damping piston, on opposite ends of the piston bore.

Patent FR-2244102-A1 (FR)
Title: Brake adjusting mechanism - has bowden operated ratchet nut at one end, elongated hole and pin at other end
IPC: B61H5/00
Filed: 1974-09-18
Abstract: The design concerns brakes used on rolling stock, where an important requirement is to maintain the minimum gap between brake disc and lining regardless of progressive wear, in order to ensure short reaction time and prevent forming of an ice crust in winter if the gap is too wide. Prior designs tended to locate such adjustments within the brake cylinder, resulting in complicated designs and poor accessibility. The present arrangement envisages the mechanism outside the brake cylinder. The mechanism operates in such a way that during a repeated application of the brakes the Bowden device automatically rectifies any deviation in the minimum gap occuring due to wear of lining.

Title: Abrasive cleaning of ingot mould walls - using compressed air turbine to spray abrasive slag particles onto mould walls
IPC: B24C3/32
Filed: 1976-08-02
Abstract: The internal walls of ingot moulds with any desired cross-section are cleaned by abrasive blasting while the moulds are in a horizontal position. A compressed fluid, esp. air, is used to carry the abrasive particles to a variable speed turbine located on the mould axis and fitted with >=2 diametrically-opposed outlet nozzles. The nozzles are pref. located in opposite directions, each at 45 degrees to the axis of the turbine; the turbine is located on the end of a flexible pipe and fed into one end of the mould, a suction appts. of known type being fitted on the other end of the mould for collecting the abrasive particles. A variable speed motor is pref. used to control the speed at which the turbine travels through the mould. The nozzles are pref. 6-9 mm dia. and located at 20-30 cm from the mould wall. The air is pref. at 5-8 bars, and the abrasive is slag grains, 2-3 mm dia. which can be collected from the suction appts., sieved, and re-used. Ten ingot moulds/h can be cleaned if 5/h by conventional shot blasting, bu the latter involves placing the moulds in a vertical position, so the invention saves time and labour costs. The use of slag as the abrasive is more convenient and less dangerous than shot.
