Abstract: Within a stationary upstanding cylindrical housing, a piston and a base member resting on the ground are separated by an expansible detonation chamber. Means are provided for feeding successive charges of a combustible gas mixture into the chamber at a rapid rate and initiating a corresponding series of gas explosions therein. Recoil of the piston following each explosion compresses a first air spring which then forcibly thrusts the piston downwardly. Piston recovery for the next cyclic operation is thereafter slowed by means of a second air spring-dashpot combination.

Abstract: A method of displacement bleaching digested, washed cellulosic pulp.  Pulp is continuously passed through successive bleaching stages, each bleaching stage having a displacementextraction loop.  Bleaching chemical is added to the pulp in each bleaching stage to effect bleaching.  Minimization of chemical consumption within an oxidative displacement-extraction loop is important in displacement bleaching, and this is accomplished by controlling the reaction rate with temperature.  The temperature in a given oxidative displacement-extraction loop (i.e. with Chlorine dioxide bleaching chemical) is maintained in the range of about 120.degree.F to less than 160.degree.F, preferably about 135 140.degree.F. A 0.5% net savings within the given displacement-extraction loop may be effected with pulp of the same quality, and a corollary savings in energy is also effected.

Abstract: A commutator motor can be set to different speeds by changing the external circuit connections between the single phase AC supply line and the stator field winding. The field winding is distributed in slots over at least part of the circumference of the stator bore and the field winding connection is switched, when going from a lower to a higher speed, in such a way that the axis of the stator field is rotated in the direction of rotation of the motor. For improved performance, the number of excitation turns may also be changed, simultaneously with the rotation of the field axis. The motor is particularly useful for automatic washing machine drives having a universal motor.

Abstract: The microtome has a specimen slide moved periodically by a drive shaft, and a blade bracket comprising a blade slide and a blade holder. A threaded spindle serves to advance the blade bracket and thus the blade. The blade is retracted from the specimen after each cutting process, independently of the advance of the blade slide. For this purpose, the blade holder is merely tilted slightly by being raised around an axis, which forms an acute angle with the cutting edge of the blade. The blade holder is raised by a lever arrangement, coupled through a shaft and a pivot bearing with the drive shaft of the specimen slide.

Abstract: The speed of travel of a lift cage is monitored by a shutdown device, comprising a cable-driven pulley with integrated ratchet wheel (4) and cam wheel. The cam wheel sets a rocker (5) with a rocker lug (5.21) into rocking movement. Rotatably mounted on the rocker (5) is an actuating lever (6.2) held in a rest position relative to the rocker by a restraining device (8) which may be a restoring spring, spring detent or a magnet. The upper end of the lever (6.2) is constructed as an actuating bracket (6.21) and its lower end as a tripping lug (6.22) projecting further than the rocker lug. Both lugs lie between two adjacent ratchet wheel teeth (4.1), when the roller (5.11) of the rocker stands on a cam lobe (3.1). When the roller (5.11) is between two cam lobes, the lugs are lifted out of the path of the teeth (4.1) and the teeth move past the lugs without effect. In the case of excess speed, the roller (5.11) lifts off the cam wheel (3). The tripping lug remains in the path of the ratchet wheel teeth. The next arriving tooth engages the tripping lug and deflects the lever (6.2), whereby the bracket (6.21) switches off the drive by way of a switch (9.1). On further rise in the speed, the rocker lug (5.21) enters the path of the ratchet wheel teeth (4.1) and leads to blocking of the cable pulley. <IMAGE>
