Abstract: Disclosed herein relates to a positive electrode for a lithium secondary battery and a lithium secondary battery including the same, and since the positive electrode contains a first positive electrode active material including an iron phosphate compound and a second positive electrode active material including a lithium composite metal oxide in a multi-layered positive electrode mixture layer, it is possible to display a large voltage deviation for each state of charge (SOC) of a secondary battery. Therefore, when applying a secondary battery, there is an advantage in that the state of charge (SOC) can be easily estimated and/or measured with high reliability. In addition, the positive electrode for a lithium secondary battery has an advantage in terms of the output performance of the secondary battery being excellent because the energy density of the battery can be increased by containing a lithium composite metal oxide in a positive electrode mixture layer spaced apart from a positive electrode current collector among a plurality of positive electrode mixture layers.

IPC: C08F14/08
Filed: 1979-05-28
Abstract: There is presented a new process for producing homopolymers and copolymers of vinyl and vinylidene halides by means of the suspension polymerization procedure. In this new process, the reactor is run a few degrees warmer than normal for the first part of the reaction and then followed by a steadily decreasing temperature throughout most of the rest of the polymerization in order to linearize the reaction rate. This allows one to charge more initiator and/or monomer to the reactor thereby increasing productivity per unit of time.

Abstract: A data transmission system to enable data to be transmitted along a transmission path at a rate C greater than the upper data rate limit A of the path. A data transmitter driven by an internal clock at C Hertz transmits data along the transmission path and at the same time also transmits a derived clock signal at a frequency C/N Hertz where < A along the path. At the receiver the data is clocked into a series of data stores under the control of the transmitted clock signal and is thereafter recombined into a serial stream under the control of the clock signal driving the receiver.

Abstract: A single field or picture of a PAL colour television signal is stored in a store and provides a signal at an input (52). The stored signal consists of 2f<sub>sc</sub> samples taken at 45° to the U-exis. The signal is separated by a filter (56) and subtractor (58) into a high frequency or chrominance signal and a low frequency or luminance signal. The chrominance signal is delayed by delay means (62) such that the chrominance components of two lines which are an odd number of lines apart are made available simultaneously. These signals are combined by switches (S1, S2) and/or combining circuits (68) to provide a signal at 4f<sub>sc</sub> which is combined with the luminance signal in a combining circuit (70) to provide a 4f<sub>sc</sub> PAL output (72). The manner of the combination of the chrominance components is changed on an 8-field cycle. In an alternative arrangement, if the PAL signal is originally stored in a store which provides outputs from more than one line simultaneously, two stored lines can be combined, and the chrominance portion of the thus-combined signal combined with the luminance portion of a stored signal to provide the output.

IPC: G11B20/14
Filed: 1979-09-28
Abstract: A phase-locked loop has a pulse forming circuit (11, 12) connected to one input of an exclusive OR phase detector (13). The pulse forming circuit (11, 12) produces fixed width output pulses for all transitions in its input signal. Variable width and frequency pulses appearing as error signals at the output of the phase detector (13) are processed in an amplifier filter (15) to produce a control signal which is proportional to the average voltage of the error signal, and which controls the variable frequency oscillator in a conventional manner. 
     Using the pulse former (11, 12) allows operation of the high gain exclusive OR phase detector (13) in applications, such as data recovery from magnetic media, where the synchronising signals appear at intervals corresponding to sub-harmonics of the clocking frequency. 
     The pulse forming circuit (11, 12) may comprise a further exclusive OR circuit (12) receiving incoming signals directly and via a delay line (11 ).

Abstract: Textile wallpaper comprising a support layer (1) bonded by an adhesive layer (2) to a fabric web (3). With this kind of wallpaper the problem is that the threads (3a, 3b) of the fabric web (3) are easily detached from the support layer (1), in particular at the cut edges of the wallpaper, making use very difficult, if not impossible.   To avoid detachment of the threads (3a, 3b), a further thin layer of adhesive (4) has been applied to the front of the wallpaper. To prevent detachment at the cut edges, it is sufficient to apply a coating (4) along the edge. By coating the entire visible surface it is possible to reduce the flammability and to improve the washability and printability. The thickness of the adhesive layer (2) which is situated between the support layer (1) and the fabric web (3) can be reduced compared with existing wallpapers. The wallpaper is intended for use in dwellings. <IMAGE>

Abstract: The present invention relates to methods for reducing the open end of drawn and ironed containers such as beverage cans (20). It is desirable to provide a maximum reduction in diameter of the open end (36) in order to reduce the quantity of material in the lid (24); but previous forming methods have resulted in localized buckling in the reduced diameter portion (32) and/or crumpling of the transition portion. The present invention has solved the localized buckling and crumpling problems by a step wherein both the reduced diameter portion (32) and the transition portion are reformed within controlled limits to provide a new reduced diameter portion and a new curvilinear transition portion. Principal uses include the manufacture of beverage cans.
