Title: Coke for foundry cupolas - coated with molten cupola slag before use to retard its oxidn. in upper part of cupola
IPC: C21B5/00
Filed: 1975-07-02
Abstract: Foundry coke is pretreated before its use in a cupola. The novelty is that each piece of coke is coated with a noncombustible material consisting mainly of slag directly obtd. from the cupola, the slag having a m.pt. >1000 degrees C and pref. 1300-1400 degrees C. The coke is pref. circulated through a molten bath of slag. and may be sprayed with a wetting agent before entering the bath, which may contain a prod. altering its viscosity and improving the coating of the coke with slag. The pref. pretreatment plant consists of a heated U-shaped vessel contg. molten slag and located near the cupola; the coke is fed into the slag and a conveyor used to remove the coated coke from the top of one leg of the "U". The use of coke in a supola is inefficient because of the high proportion of CO in the gas leaving the cupola throat. By coating the coke with slag which does not mealt until 1300-1400 degrees C., the oxidn. of the coke is delayed in the upper part of the supola.

Title: Radiation detected by latent metastable state of particles - changed into normal state by incident radiation
Inventor: DRUKIER ANDRZEJ KAMIL
IPC: G01T1/16
Filed: 1975-11-28
Abstract: A method of detecting electromagnetic or particle radiation utilises the phenomenon of the transition of a homogeneous grain of a superconducting substance of the first type out of the metastable superconducting state into the normal state; this transition is produced by the effect of a photoelectron expelled by the impact of the photon or particle on the grain. The superconductivity and the Meissner effect remain in a latent state in the particle after the critical value of the surrounding magnetic field has been exceeded, producing a 'superheated' condition of the metastable state. A spherical homogeneous grain of the material suddenly loses this superconductivity when subjected to beta radiation. This loss of superconductivity is detected by measuring an electrical or magnetic variable associated with the change of state. A probe or detector is described which contains superheated metastable particles surrounded by a dielectric. Pref. dielectric material is epoxy resin.

Title: Constant speed and tension beam let:off motion - adjusts to tension via infinitely variable pulleys and gears
Inventor: SANTUCCI NICOLA
IPC: D03D49/10
Filed: 1976-12-10
Abstract: An arrangement for maintaining the unwinding of the warp threads from the beam in a loom at constant speed and tension, includes a train of intermeshing and easily interchanged gear wheels together with a pair of split, "V"-belt pulleys forming a variable transmission. The firt variable speed pulley is driven from the loom main shaft, and the variation of the transmission ratio of the belt pulleys is effected bya system of connecting rods and levers responding to the tension on the warp threads. The gear train is formed by two pairs of wheels linked by a worm to the beam. One of the gears is keyed on the worm shaft, and the worm engages with a worm wheel attached coaxially to a gear wheel engaging with another on the beam shaft. The linkage responding to the warp yarn tension includes a rocker with a cylinder at one end over which the warp ends run, and a vertical connecting rod at the other which joins a horizontal lever with a counterweight. This is connected to the levers altering the widths of the variable speed "V"-belt pulleys. The arrangement improves the working conditions of the variable speed belt transmission so that it works accurately and reliably at very low speeds. The variable speeds pulleys are driven continuously by the loom main shaft turning at the same high speed so that they are not dependent upon the transmission through a train of gears. The speed of the beam cna thus be accurately adjusted.

Title: Capacitor welding machine control - for low-loss current setting by pulse sensor and logic multipliers and adders
Inventor: BELOV A B
IPC: B23K11/26
Filed: 1977-02-18
Abstract: A capacitor welding machine has a control system for the thyristorised inverter, which governs the capacitor discharge into a welding transformer. The control system includes a sensor for start and end of the welding current pulses. Its output is passed direct, and via a controller for the prim. current pulse interval, and via a sequence switch for the thyristor control, to a logic signal multiplier. Its other inputs come from a controller for the duration of the time intervals of which the welding current pulse consists. Logic adders combine these signals for the thyristor firing units. High welding quality is obtd. because the current pulses have the optimum shape. All metals including heat-resistant and hardening steels can now be welded on the capacitor welding machine. The quality of the weld can be controlled effectively.

Title: Dispositif de regulation de la tension des rubans de roulement d'une machine a rectifier les engrenages
IPC: B23F5/08
Filed: 1977-07-29
Abstract: Lorsque la surépaisseur dans l'entredent de la pièce 3 est uniforme les tensions des rubans 12, 13 sont égales. Si un excès de surépaisseur se présente sur le flanc 37, l'effort axial résultant sur la meule devient unilatéral, et la tension et l'allongement des rubans 13 augmentent. L'extensomètre 19 indique alors une baisse et l'extensomètre 20 un accroissement de la tension par rapport à la valeur de repos présélectionnée. Il en résulte que l'électro-aimant 29 déplace le tiroir 27 et qu'une pression supplémentaire est appliquée par la conduite 26 sur le piston 24, ce qui veut dire que la tension des rubans de roulement 13 donc de l'extensomètre 20 est accrue jusqu'au rétablissement d'une tension égale à la tension présélectionnée dans les rubans 12 et l'extensiomètre 19. On obtient ainsi une haute précision dans la rectification.
