In additiont, the analog contains a feedback loop to,simulate the accommodation and refractor nature of the neuron. The threshold element is a rectangular-hysteresis-loop core having several.input windings, an excitation winding, and an output winding. An experimental model of the ferristor was con- structed to operate at frequency up to 10 kcs, accommodation time of.. about 5 microseconds, an absolute refractor time of about 100 micro- .,seconds, a relative refractor time of about 1100 microseconds, and a synaptic delay of about 1-2 microseconds. These parameters could. be modified at will. The ferristor can be used as a logic element for computers and is also used at-the computation ce'nter(headed by V.:I.

The unit (see Fig. 1) is based on core-diode building blocks and use-q the 50 cps line frequency for synchronization. The 6.3 v 50 cps voltage derived *from.the power line is shaped by two delay elements and an inhibi.tor gate which gives out 20 msec system clock pulses. The flip-flops are arranged into a shift registex circuit in which upon command the T3 flip-flop generates a start pulse and succeedingi flip-flops (T8, TO T92 T53 T10), actuated for every 20 msec, open the corresponding gates between the accumulator output of.computer D and a single output telegraph line C. The stop pulse is generated when T61 T11 are active, after which an end of message may be sent. The unit may accomodate other codes if its shift register is expanded accordingly.

ABSTRACT: Detailed theoretical investigation of the stress state of the tail of a blade is difficult@and therefore strength calculations are usually made on the basis of "conditional" methods, "the tooth" being calculatedfor shear and crushing and the neck for tension, Levin, A.V.(I). Photo.-e,lastic investigations (2 and 3) have revealed that the real stress. state differs considerably from that obtained on the basis of simplified assumptions. Particularlyconsiderable~.local-..,,, stresses were revealed at the angles of the tail with stress concentration coefficients reaching in some cas.es the values of two or even three. These results contradict to Card I some extent the experience over many years of trouble-free operation of such tails designed on the basis of simplified. calculation methods. This contradiction can be@explained by Design of a T-tail of a turbine blade according to the principle of limit loads. (Cont.) 24-5-18/25 calculation according to the principle of limit loads. The existence of slight local plastic deformations does not generally bring about a fracture of the tail and is, therefore, admissible. In this paper the limit load is determined for a T-tail and also the most rational configuration of such a tail. It is assumed that the tail fills completely the slot in the disc and tha't-it:-'cannot increase in.thickness during its deformation. The contact between the tail and the rim of the disc is,effected along the upper edge of the tooth and the contact pressure is assumed constant; according to Drucker (4) the obtained value of the limitload will be lower than the real one in this case. The centrifugal force of the tail is added to the centrifugal force of the blade, thus assuming that there are no body forces in the tail. It W'as.found thatlu'he entire area.which is in the plastic state is of hyperbolic shape. The.theoretical conclusions are.utilised for calculating a practical example. Comparison of the Card 2/3 configuration of tails which were, in operation for a long. time is very similar to the configuration arrived at theoretically in this paper. AUTHOR: Rozenblyum, V.I.

In the first problem, a general solution on the basis of the accurate equations has not been, ar,case when the exponent m: cul obtained.
