Title: Contact lens construction
Inventor: BARNETT HOWARD J
IPC: B29D11/00
Filed: 1981-11-18
Granted: 1986-01-02
Abstract: arious forms of multifocal contact lenses can be produced having improved properties. The surface of a lens (1) to be polished is brought into contact with a polishing compound (19) associated with a flexible (but non-resilient) sheet (18), causing the sheet (18) to flex. Fluid pressure is applied to the sheet counteracting the flexing as a result of lens contact, so that polishing compound associated with the sheet makes contact with the lens surface with uniform force distribution. Relative rotation between the lens (1) and sheet (18) is effected so that all portions of the lens surface in contact with the polishing compound are polished to the same extent. The lens is then ground to provide a multifocal lens. A hydrophilic or silicone multifocal contact lens having desired distance and intermediate powers may be constructed by acting on the lens (2) so that it is capable of accepting grinding activity, and the grinding it without distorting it. The lens (2) may be backed by a chuck (34) or hard lens (3), or frozen, and ground by grinding apparatus (60) while backed or frozen.

Title: Electrolytically corrosion protected hot water tank - with sacrificial electrodes
IPC: C23F13/02
Filed: 1971-09-06
Abstract: The electrodes, which not only protect the tank, but also the pipes connected to it, and through which a d.c. current derived from an outer current source is passed, are disposed in the tank such that 1/3 of their mass not counting the mass required for protecting any structures is inside the tank. The portion of the tank near the outlet is defined as 1/3 of the tank volume between the water in-and outlets. The gap between the electrodes and the tank wall vary with the electrical conductivity of the water, sacrificial Mg-anodes being employed. The layout reduces the necessary dwell time for the water in the tank and obviates the need for a separate reaction chamber.

Title: Opening window unit esp. for caravan roof light - has leaf spring pairs on opposing sides to provide over-centre action
IPC: E04D13/035
Filed: 1971-11-25
Abstract: The roof light is mounted by four, flat leaf springs to its frame. Each spring has one end engaged with the roof light and its other end engaged with the frame. The distance separating each pair of engagement points is less than the length of the associated spring so that the springs adopt a curved configuration affording the over-centre action to retain the roof light either open or closed. Stops on the frame limit the degree of opening; by providing adjustability for the stops, different degrees of opening can be made available. The springs may be formed with eyes on their ends to fit the window frame.

Abstract: A speech synthesis system has a word lexicon stored in a storage device for managing word information, a speech lexicon stored in the storage device for managing speech data. A language processing module carries out language processing of an input text by using the word information, and an acoustic processing module generates a synthesized speech signal by using the speech data in response to a processing result of the language processing module. A D/A converter converts the synthesized speech signal to an analog signal. The system further includes a detection module detecting performance or conditions of a hardware part of a computer in which the system is implemented, and an adjustment module adjusting the word information and/or the speech data which are to be given to the language processing module and the acoustic processing module, based on a detection result of the detection module. Therefore, an optimum speech-synthesis processing suitable for any computer is performed.
Patent JP-S6016582-B2 (JP)
IPC: G10L19/00
Filed: 1977-03-04
Abstract: A frequency analyzer of a predetermined number of channels comprises a digital band-pass and a digital low-pass filter section. A preselected number of digital samples sampled with a sampling period are stored in a buffer memory to be read out in each sampling period. A band-pass parameter memory memorizes for the respective channels band-pass filter impulse responses, each having preselected values, equal in number to the preselected number. A band-pass filter calculator calculates a convolution of each read-out digital sample and the preselected values of each response. The low-pass filter section produces frequency analysis results for the respective channels in each analyzing frame period equal to a first prescribed number of the sampling periods. A low-pass filter impulse response having a duration equal to the frame period multiplied by a second prescribed number and prescribed values, the predetermined number in each sampling period, is memorized in a low-pass parameter memory with its phase or the duration successively shifted by the frame period. A multiplier calculates products of each convolution and the prescribed values of the respective memorized responses read out in an interval of production of that convolution. Absolute values of the products are accumulated in an accumulator register memory according to the respective channels and the respective phases and produced therefrom as the analysis results for the respective channels in those of the sampling periods which are spaced by the frame period and at which the respectively shifted durations have ends, respectively.

Abstract: For the high-speed data access machine, data is distributed in a plurality of hard disk drives coupled to slave processors to achieve ever-higher data reliability and maintenance. One master processor is provided with a plurality of slave processors, each of which is coupled to two hard disk drives containing the same data. A synchronous signal permits two hard disk drives to operate in synchronous rotation in half-a-turn phase difference from each other. The hard disk controller writes the same data in both hard disk drives but reads data from whichever hard disk drive requires less access time to obtain the data. A plurality of hard disk drives holding exactly the same data improves data reliability. Also, by rotating a plurality of hard disk drives in different phase, the rotational delay in data access is cut by half.
