摘要： The disclosure describes an improved analog-to-digital converter which enables the use of a reference voltage having the same polarity as the input analog voltage being converted. The converter employs an operational amplifier having a capacitive feedback network, an inverting input, and a non-inverting input. The inverting input is periodically disconnected so that the output of the operational amplifier slews to a new value without substantially changing the voltage across the capacitive feedback network.

摘要： A beam of concrete has similar end pieces at each end spaced apart by an internal reinforcing elongate cage of rectangular cross-section formed of four longitudinals (10) having a lengthwise series of hoops therearound. Each end piece comprises a rectangular plate (12) transverse of the beam's longitudinal axis. The plate (12) has at least four apertures (14), normally one at each corner, and similar angular wall surrounds (16) outstand from the inner face of the plate (12) and from around the apertures (14) to separate each aperture from the others. Two starter bars (20) are provided for each surround (16), being welded, one to each limb of the surround (16) adjacent to the corner on the side remote from the corresponding aperture. The bars (20) are spaced from each other a distance to accommodate therebetween a respective longitudinal (10) of the cage. Nut and bolt fastenings (24) are used to secure abutting plates (12) of adjacent beams in a multi-beam assembly.

摘要： A method to improve the health and growth of suckling dairy calves on dairy farms includes supplementing calves' diets with a ruminal fluid preparation obtained from the rumen of a cow. This supplement provides the calves with the protection needed to develop faster and healthier. It also leads to a decreased incidence of scours in the treated calves.

摘要： An encoding transmitter is disclosed which includes a modulator providing a means to modulate a carrier wave selectively with a first or a second modulation frequency or pattern to provide first and second modulation patterns respectively. Also a third modulation pattern may be established by providing successive portions of the first modulation frequency and the second modulation frequency during a given time period. A data selector is controlled by data select control signals which are obtained from a counter counting from the first modulation frequency signal. Programmable means include a multi-position switch to program the input channels of the data selector so as to control whether the first or the third modulation pattern is that which modulates the carrier wave during any given unit of time.

摘要： A receiver and decoder is disclosed wherein the receiver may be used as a remote control receiver in conjunction with a transmitter transmitting a carrier modulated with an encoded data train of first and second modulation frequencies for first and second modulation patterns. A third modulation pattern may be established by providing successive portions of the first modulation signal and then the second modulation signal during a given time. If the receiver is on the same carrier frequency and is set to receive the same modulation pattern sequence as in the encoded data train from the transmitter, then the receiver has an output which may be used to control some remote load. This may be a garage door operator to open a garage door, for example.The decoder in the receiver is responsive to the modulation signals and a signal discriminator discriminates among the three different modulation patterns or logic conditions of bits. A data comparator is connected to receive the logic conditions of the bits and a programmable switch provides a programmable bit input to the data comparator which compares sequentially bit by bit the information from the encoded data train with the information from the programmable switch to determine if they are the same or different. When a group of bits compares favorably then an output signal is given from the decoder to control the remote load. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
