Title: Polymers of unsaturated acids
Inventor: HAUGHTON MICHAEL HARRY
IPC: C08F2/10
Filed: 1983-06-16
Granted: 1986-10-16
Abstract: Water soluble polymers from acrylic acid optionally with other monomers have a narrow molecular weight distribution and are made by continuous loop polymerisation particular in the presence of sodium chlorate and sodium metabisulphite as redox initiator. The loop polymerisation gives more uniform product than batch operation and the narrow molecular weight distribution gives polyacrylates useful in water treatment, scale inhibition and as dispersants.

Abstract: A method and a device for the control of a joint between a first element (18) and a second element (21). The first element preferably is an end element of a container and is inserted in an opening in said container such that a rim is formed around the opening and includes a joint (16). The rim allows the placement of a radiation or wave energy transmitting source (13) at one side thereof and a detector device at the other side. The radiation or wave energy source has a capacity of penetrating, preferably fully, the rim and illuminating said rim by a small dot (14), which is scanned crosswise the width of the joint by a scanner device. The container (10) is rotated around an axis (12) and the detector device (22) registers the characteristics of the radiation that passes the joint and/or is reflected at the joint and which originates from a repeated "point illumination of the joint". By placing the detector device at a sufficient distance from the rim there is obtained a magnifying effect in the detector, which allows the detection of very small changes in the quality of the joint. The method and the device are especially suited for joints comprising substantially plastics material and where the product, which may affect the joint also substantially consists of an organic material, for instance a food product.

Abstract: A high efficiency power converter is achieved utilizing a resonant DC link between a DC source, such as a converter rectifying power from an AC power system, to a variable frequency voltage source inverter. A resonant circuit composed of an inductor and capacitor is connected to the DC power supply and to a DC bus supplying the inverter and is caused to oscillate stably at a high frequency to provide a uni-directional voltage across the DC bus which reaches zero volts during each cycle of oscillation of the resonant circuit. The switching devices of the inverter are controlled to switch on and off only at times when the DC bus voltage is zero, thereby eliminating switching losses in the inverter. The resonant circuit can be caused to oscillate utilizing pairs of switching devices in the inverter or a separate switching device across the capacitor, which again are caused to switch on and off only at times of zero voltage on the DC bus. For AC to AC conversion, enabling bi-directional power flow, the switching devices of the power source which converts AC power to DC power may have switching devices which are also switched only at the times of zero voltage so that switching losses in these devices is also minimized.
