Abstract: 346,609. Magnetos ; inductor machines. FABBRICA ITALIANA MAGNETI MARELLI, 22, Corso Venezia, Milan, Italy. June 2, 1930, No. 17049. Convention date, June 25, 1929. [Class 35.] For advancing and retarding the ignition in magnetos for internal combustion engines, engagement between the rotor and the driving shaft is effected by means of an intermediate member located partly in a hollow portion of the driving shaft and partly in the rotor shaft, the intermediate member engaging one of the shafts by helical teeth and the other shaft by straight gearing and being axially displaceable. The rotor 1 is mounted on a sleeve 2 having at one end internal teeth 5 formed parallel with the axis of rotation. The hollow driving shaft 6 is mounted loosely inside the sleeve. The shaft 6 is formed with quickpitch helical grooves 9 at its open end and these grooves engage a thread 11 on a bush 12 which has also straight teeth 13 engaging with the teeth 5 of the sleeve 2. The contact-breaker is operated by a cam 26 solid with the sleeve 2. In a casing 14 removably mounted on the magneto end, straight slots 15 are formed parallel with the axis and the slots engage the ends of a cross member 16 acting on a central rod 17, the opposite end of which abuts against the end of the bush 12. A drum 18 mounted to rotate within the casing 14 has helical slots 19 which are also engaged by the cross member and the drum can be rotated by means of an external lever 25 which engages pin 21 on the drum passing through arcuate slots in the casing. Normally, the spring 8 maintains the bush 12 in the position shown so that the rotor is in the position of maximum advance. Actuation of the lever 25 causes inward movement of the member 16 and the rod 17, and the bush 12 is displaced to the left. The sleeve 2 carrying the rotor accordingly is moved angularly with respect to the driving shaft 6.

Abstract: 761,980. Blood cell counting apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 8, 1954 [June 19, 1953], No. 17095/53. Class 81(2) [Also in Group XL(b)] In an apparatus for counting particles in suspension in a fluid medium, e.g. blood corpuscles, in which a known volume of suspension is injected into the fluid flow past a counting station the means for injecting the suspension comprises a capillary 5 of known volume communicating through a second narrower capillary 4 with the fluid flow, the junction between the capillary bores being discontinuous, and means for providing a suction at the point where the second capillary enters the fluid flow, sufficient to overcome the surface tension forces when the surface of the liquid column in the capillaries is in the first, but insufficient when it is in the second capillary, so that injection of the suspension stops when the surface reaches the abrupt junction of the capillaries. In the embodiment the counting station (not shown) comprises a light source the beam from which is projected across the path of the suspension leaving capillary 4 on toa photomultiplier, the output pulses from which operate an electronic counting register. The suction at the mouth of capillary 4 is determined by the fluid head h between surface of reservoir 11, from which the fluid flow is drawn, and the open end of capillary 5. Sprengel pump 7 which forms part. of a closed circuit including mechanical pump 8 and air trap 17 draws fluid through the chamber 1. Reservoir 11 is supplied from the pressure side of pump 8 through a filter, e.g. of ceramic, preventing recirculation of particles, a constant head being maintained by overflow 12. Fluid from the overflow may be reintroduced continuously through a small orifice on the suction side of the Sprengel pump or the system may be periodically topped up from reservoir 15 through two-way cock 20. For a testing operation pinch cock 14 is closed so that the full suction of the Sprengel pump is available at the mouth of capillary 4, and test tube 6 containing a diluted suspension, e.g. of blood corpuscles, is racked up so that the suspension is drawn through the capillaries to flush them and refill them with test suspension. The test tube is then withdrawn thereby operating microswitch 19 to start the counter and simultaneously to release the cock so that the injection rate of the suspension is reduced to a convenient one for counting.
