Title: Sliver layer - has a guide which induces a shaped path on sliver as it is projected into the can
Inventor: LENK ERICH DR ING
IPC: B65H54/82
Filed: 1980-04-16
Abstract: The shape of the coils of sliver in the can is determined by the movement of the layer. This projects the sliver into the can on a reciprocating, elliptical, egg-shaped, figure-of- eight or an interlocking path into the can, with the path ends following a curve. The process prevents any ballooning in the sliver path, and also ensures that the sliver can be drawn out of the can smoothly, without snagging or knotting. The sliver guide moves round a stationary cage which is shaped at the end, over its horizontal cross section, in the shape of an ellipse or an egg-shaped oval. Or the guide can project the sliver into the can so that is describes a shaped path before landing on previously-laid sliver layers.

Title: Automatically measuring tensile pull using circuit - which draws billet or slab out of mould in continuous casting plant
Inventor: SMIRNOV GENNADY ALEKSANDROVIC
IPC: B22D11/20
Filed: 1980-05-09
Abstract: The circuit includes electronic devices making allowances for the wt. of the mould; the inertia of the mould; and the oscillation of the mould along its axis during casting. The pref. plant includes a load cell measuring the tensile pull on the mould exerted by the rolls which draw the billet out of the mould. The load cell receives a signal from a unit to compensate for the wt. of the mould, and delivers a signal to a summing unit, which also receives a signal from a transducer measuring mould acceleration. The summing unit is connected in an electronic comparator circuit which records the force pulling the billet out of the mould. For example, in the continuous casting of steel, so excessive pulling forces, which could produce cracks in the billet, are avoided.

Title: Regulating device for the automatic adjustment of the transmission ratio in an infinitely variable hydrostatic transmission
Inventor: GOELZ ROLF
IPC: F16H61/42
Filed: 1981-03-14
Abstract: The invention relates to a regulating device known per se for the automatic adjustment of the transmission ratio in an infinitely variable hydrostatic transmission in the drive for a machine as a function of the working pressure of the transmission. The aim of the invention is to design a regulating device of this kind in such a way that on the one hand the machine is protected from overloads but that, at the same time, the best possible use is made of the capacity of the machine concerned and hence the productivity of the latter is increased. This object has been achieved by the insertion, in the control circuit consisting of a desired speed transmitter for the output speed of the transmission, a controller and an electromechanical adjusting device for the delivery rate of the pump component of the transmission, of a time-delay relay with an adjustable delay time which interrupts the control circuit when the selected maximum permissible working pressure in the transmission is exceeded and at the same time initiates an adjustment of the adjusting device in the direction of the zero position of the transmission ratio in the transmission, while on the expiry of a selected delay time said relay closes the control circuit again automatically and thereby initiates an adjusting movement in the direction of an increase in the output speed of the hydrostatic transmission until the set desired value for the maximum permissible working pressure is exceeded again.

Title: Fuel injection control system for an internal combustion engine
Inventor: HIGASHIYAMA KAZUHIRO
IPC: F02D41/00
Filed: 1981-03-18
Abstract: A fuel injection control system controls the quantity of fuel injected into an internal combustion engine such as, for example, a V-8 engine. Such a control system first calculates a basic quantity of fuel to be injected per revolution Tp, where Tp = Q/N x constant, Q = inlet air flow quantity, N = number of revolutions of the internal combustion engine, calculates correction coefficients (COEF, alpha L,  alpha R) on the basis of various other operating parameters of the internal combustion engine, for example the cooling water temperature, and an air-fuel mixture ratio of each bank of cylinders by feedback control and combines one of its numerical results with the numerical result in order to obtain a pulse width Ti, which indicates a quantity of fuel per revolution Tp and finally opens one of the two or both groups of fuel injection devices (4, 4') in such a way that when the inlet air flow volume Q is greater than a certain value Qo the fuel injection devices of both groups are opened simultaneously in order to inject the fuel synchronously with a half revolution of the internal combustion engine during an interval, which is determined by Ti = 1/2  x Tp x COEF, and, when Q is not greater than Qo, the fuel injection devices of one group are opened alternately in order to inject fuel during a time interval, which is determined by T1 = T0 x COEF x ( alpha L or  alpha R).
