Abstract: 852,509. Hydraulic shock absorbers. MEBOE Ltd. Feb. 22, 1957 [March 1, 1956], No. 6505/56. Class 108(3). An hydraulically damped buffer comprises a metering tube 20 which is mounted so as to be removable. In operation, on compression, liquid is forced from a cylinder space 26 through an orifice 29 in the metering tube 20 and thence into the interior space 27 of a plunger 11 where it acts upon a piston 15 to compress springs 16, 16a. On rebound, liquid returns through a peripheral series of passages 22 and lifts a valve 23 which is spring loaded towards a closed position by springs 25. The metering tube 20 has a curved end surface 19 to provide a self centring action relative to the piston orifice 12. The metering tube 20 may be replaced by a tube having a plurality of orifices 29 of different sizes (Fig. 3, not shown). Alternatively the orifice or orifices 29 may be replaced by a single elongated orifice the width of which varies along the length of the tube so as to provide a damping effect which varies with the stroke of the device (Fig. 4, not shown). In the form of metering tube 20 shown in Fig. 5, in addition to the orifices 29 there is a spring loaded piston 35 which acts as an unloading valve. An external spring may be provided to act between shoulders 32 and 33 of the buffer.

Abstract: 725,706. Blinds. STOREN-UND MASCHINENFABRIK E. SCHENKER AKT.-GES. March 11, 1953 [March 29, 1952], No. 6695/53. Class 20 (3). In a venetian blind, lifting the slats and altering their inclination are effected by the same shaft 2, the lifting cords (not shown) being wound on spools 3 fast on the shaft 2 and each ladder tape 14 being secured at 13 to a sleeve 6 which houses a spool 3 and is freely rotatable on the shaft. The sleeve 6, which is apertured at 7 for the passage of the lifting cord, is clutched to the spool 3 by a spring 10 which embraces a grooved extension of the spool and is connected at one end to the sleeve. When the shaft is turned in one direction, the spring 10 is tightened on the spool and drags around the sleeve 6 until a projection 11 on the sleeve hits a stop 12. Further turning of the shaft adjusts the level of the slats without further alteration of their inclination. When the shaft 2 turns in the opposite direction, the grip of the spring is loosened, but not sufficiently to prevent the sleeve from following the spool around until the other limit of slat inclination is reached. In view of the weakened clutch action, no stop is necessary in this direction. In a modification, two oppositely acting springs 10 are arranged on each spool, and two positive stops 12 are provided. The sleeve 6 may be replaced by a rocking yoke or fork.
