Title: Circular extrusion apparatus providing for rotation around the extrusion opening
IPC: B29C48/90
Filed: 1976-02-11
Abstract: Apparatus for producing tubular sheet material by extruding a fluid polymer material through a hollow centered die having an annular extending continuous or discontinuous extrusion orifice exit rotated about the die axis to discharge therefrom a continuous or discontinuous annular-form polymer structure which is collected on a generally cylindrical supported surface advancing through the hollow center of said die. The collected structure undergoes attenuation at an angle to the general extrusion direction because of the die exit rotation and consequently, has a grain therein extending at a significant angle, e.g. helically, to the general extrusion direction. The collecting surface may be formed separately from the support, e.g. by one or more endless belts passing either longitudinally or helical around the support so as to collectively define a cylindrical surface in the collection zone or combined with the support, e.g. as a solid toroidal shaped member having its lengthwise axis passing through the die center and advanced along that axis. The extrusion die can have an inlet channel extending generally around the exterior thereof into which the polymer material can be delivered in pressure-free fashion and vanes or grooves can be associated with the inlet channel to assist in feeding the polymer material to the die exit orifice.

Abstract: A device for producing a textured effect in warp-knitted fabrics by varying the tension of the warp threads in a random manner during knitting comprises a series of closesett metallic discs on a revolving shaft, each having an eccentric pin projecting from one face of the disc. The position of the pins on neighbouring discs is randomly variable. The warp threads pass between the discs, those threads corresp. in position to the pins on the discs being alternately raised and lowered as the shaft rotates, giving variations in thread tension which produce intermittent variations in the surface character of the knitted fabric. The device is simple and reliable, and can be added to existing machines without difficulty. IT gives warp-knitted fabris a novel appearance, with random textured patterns of great variability, which can be simply altered in length, intensity and distribution.

Title: A method of controlling the working distance between first and second cylindrical surfaces of a staple fibre treatment machine and apparatus for carrying out the method.
IPC: D01G15/36
Filed: 1979-04-20
Abstract: The working conditions between two rotating cylindres (4, 5), which are provided with a point clothing (9, 19) and are processing or mutually transferring a fibre web, of a processing machine of the staple fibre spinning plant are always maintained on a predetermined value by adapting the distance between the surfaces of the two cylindres (4, 5). For this purpose moving means (21) are used, which permit very precise setting of the distance between the rotational axes (8, 14) of the two cylindres (4, 5), and which are controlled by control means (22). To the control means (22) the measuring signal of a characteristic directly connected with the diameter of one of the cylindres (4 or 5), as scanned by a measuring element (25), is transmitted, and the control means (22) control the moving elements (21) in function of this characteristic. Thus complete elimination of the disturbing influences of the centrifugal force and of the increase in temperature of the cylindres onto the working conditions is achieved.

Title: Contour and width gauge for paneled containers
IPC: B07C5/12
Filed: 1979-12-12
Abstract: Method and apparatus for detecting bulged and sunken sidewalls and incorrect widths on paneled containers. Containers to be inspected are moved along a conveyor. Two groups of three LVDT's (generally opposite from one another) are utilized to measure the distance between each of three points on the container sidewall and a reference line. The measurements are fed to a circuit which determines the deviation of one of the three points from a line passing through the remaining two points. The amount of deviation is utilized to determine whether or not the sidewall is bulged or sunken. Measurements from each pair of opposing LVDT's are fed to a circuit which determines the width of the container at three different heights. The width values are compared to predetermined limits in order to determine if the container width is acceptable. The timing of measurements is controlled by the use of photocell sensors, which detect the passage of a container past particular reference points. The positions of the sensors are adjustable in order to permit different types or sizes of containers to be inspected. In addition, a sensor can be employed to permit accurate width measurements to be made on container with bowed panels.

Title: Laundry or dish-washing machine
IPC: D06F34/24
Filed: 1980-02-26
Abstract: In a laundry or dish-washing machine, a thermostat compares the temperature of the washing liquid with at least two control temperatures which can be selected by the user independently of one another. The change of state of the thermostat output controls the advance of the washing machine programmer when the washing liquid has reached the lowest of the control temperatures. This allows the user to set a different washing temperature from that determined by the programmer. In one embodiment, Figure 2, a temperature transducer Rt immersed in the washing liquid comprises a resistor with a negative temperature coefficient and is included in a resistor bridge connected across a constant voltage source U. The transducer Rt supplies a voltage Vt which decreases as the liquid temperature increases. The thermostat comprises two voltage comparators IC1 and IC2 which each at their non- inverting inputs receive the voltage Vt and at their respective inverting inputs two control voltages VC1, VC2 which vary in inverse proportion to the two selected control temperatures. The outputs of the comparators IC1 and IC2 are interconnected and their output signal (voltage VS) controls the advance of the programmer when the voltage Vt reaches the value of the higher of the two voltage VC1, VC2.
