Abstract: A semicylindrical roofing member includes an arch-shaped carrying rib and one cylindrically curved plastic sheet that rests on the carrying rib. At least one non-extensible strap spans the plastic sheet and holds it to the carrying rib. This strap is releasably attached to the carrying rib by catches at its ends. A strip of soft flexible material is positioned between the strap and the plastic sheet on the carrying rib and is compressed by the strap. As a result, the strap is held in position on the sheet under tensile stress and thus secures the sheet to the rib.

Abstract: Herbicidally active thiolcarbamates are employed in combination with certain substituted carbamates having the formula
     in which
     R 4  and R 5  are each methyl,   R 4  and R 5  conjointly form C 1 -C 4  alkylenedioxy,   R 4  is -CF 3  and R 5  is hydrogen, or   R 4  is -CH 2 Br and R 5  is hydrogen.     
In a typical application, the carbamate is included in sufficient quantity to lessen the rate of soil degradation of the thiolcarbamate. As a result, the herbicidal effectiveness of the thiolcarbamate is enhanced and prolonged, rendering a single application of the herbicide effective over a longer period of time.

Abstract: A color synchronizing circuit comprises a phase locked loop which includes a voltage controlled oscillator including a ceramic vibrator. Phase comparison is made of an intermittent color burst and the output of the voltage controlled oscillator and the phase comparison output is applied to a low pass filter. The low pass filter provides a control voltage associated with the phase difference of these two signals to the voltage controlled oscillator. The frequency variable range Δf of the voltage controlled oscillator is selected such that a relation Af<±f H  is met with respect to the repetition frequency f H  of the color burst. The low pass filter comprises a dual time constant circuit, which sufficiently attenuates a beat signal from the phase comparator, thereby to make narrow the pull-in range of the phase locked loop. On the other hand, a sawtooth waveform voltage of a stepwise fall is obtained from a sweeper circuit and is applied to the voltage controlled oscillator together with the output voltage from the low pass filter as a control voltage.

Abstract: In a piano a panel, which takes the place of the usual cast iron string plate or frame, is provided for supporting the strings. The panel is a sandwich construction making it exceptionally strong and capable of withstanding the string loads without bending or otherwise yielding and without requiring auxiliary support such as the massive wooden backs or trusses to which cast iron string plates are usually attached. The string panel has a relatively thick low modulus of elasticity core layer, a portion of which is made of laminated hard wood to serve as a pin block, and relatively thin layers of high modulus of elasticity material, such as steel, bonded to the core layer. If desired the string panel may be used as the main frame of the piano to which other major components, such as the soundboard, key bed, side cheeks, housing and feet, are directly attached.

Abstract: An electron beam exposure system of a variable shaped electron beam type in which an input pattern of any geometrical shape is decomposed into rectangular patterns of a given size, whereby the pattern is exposed by an electron beam having a cross-section corresponding to the decomposed rectangular pattern. Data for the input pattern is compared with data for the rectangular cross-sectional pattern of the electron beam in a comparator (3). When the comparison results is that the input pattern should be decomposed into rectangular patterns, the former is decomposed into two sub-patterns, one of which is outputted while the other again undergoes the comparison with the rectangular pattern parameters. The processing of decomposition can be executed at a very high speed in a pipelined system (Fig. 7) which includes a plurality of processing stages of similar arrangement.

Abstract: In a loop network system comprising a plurality of stations connected by a loop-shaped transmission path (38), a particular one (30) of the stations transmits, to the path at a predetermined period, a synchronization signal block serving to trigger the other stations (31-36) and to define a highest degree of priority for transmission. A trigger signal block is also transmitted from the particular station to the path so as to define a lower degree of priority each time when a transmission right is seized by the particular station within the predetermined period. Each of the other stations transmits a transmission signal block to the path by seizing a transmission right in consideration of the degree of priority indicated by each of the synchronization and the trigger signal blocks. Each transmission right is given to each station when no signal block is present on the path. A pair of token blocks may be used to guarantee communication of the highest degree of priority and another communication of the lower degree in the predetermined period.

Abstract: A method and apparatus for determining the rate of flow of a liquid in a selected region of a body by nuclear magnetic resonance techniques. 
     The method includes a sequence of applying a first magnetic pulse (B 1  (90°) ) effective to excite nuclear magnetic resonance of a chosen nucleus within the liquid preferentially in a slice of the body which includes the selected region. A period of time (to) is waited and then a second magnetic pulse (B 1 (90°) ) is applied which is effective to excite nuclear magnetic resonance of the nuclei preferentially in the slice, and the free induction decay signal is measured. The whole sequence is repeated for different values of the period of time (to). The values of the period of time (to) and the corresponding measured signals are then related to the rate of flow of the liquid through the slice.
