Title: Liquid crystal display devices
IPC: G02F1/13357
Filed: 1978-07-31
Abstract: The invention relates to providing good contrast in displays in which one or more display characters of a liquid crystal cell are depicted in colour against a background by electrical addressing of character or background. In this invention the cell 1 in use selectively exhibits optical scattering over either character or background areas, light incident on a dye is partly converted to fluorescent light, and the latter is scattered from the scattering areas of the cell. A colour selective reflector 19 is spaced 21 from the rear 7 of the cell. The fluorescent dye may be dissolved in the liquid crystal layer 3 of the cell, or incorporated in a plate 33 of plastics material bonded to the front 5 of the cell. The cell may exhibit a phase change or cholesteric bistability effect using a mixture of 10% cholesteryl nonanoate (CN) +90% 4,4'-n-pentyl cyanobiphenyl, dynamic scattering (p- methoxybenzylidene-p'-butylaniline MBBA), or a cholesteric texture change effect (MBBA + CN). <IMAGE>

Patent GB-2012130-A (GB)
Title: Making bubble domain devices having contiguous propagation elements
IPC: G11C11/14
Filed: 1978-10-17
Abstract: This invention relates to a method of making bubble storage devices having contiguous propagation elements. The contiguous elements can have any shape, such as disks, diamonds, or blocks, etc. The mask which is used to define the contiguous elements is divided into two more identical, isolated arrays. A first exposure through this mask is used to produce propagation elements 44', 46', 48' which are separated from one another. The mask is then spatially displaced and a second exposure is done. This second exposure produces propagation elements 44'', 46'', 48'' which lie between the separated propagation elements produced with the first exposure and which are contiguous to these first propagation elements. Consequently, rather than using a single mask exposure to simultaneously produce all of the contiguous propagation elements, the present technique uses successive exposures to produce the contiguous elements. <IMAGE>

Patent GB-2028517-A (GB)
Title: Testing digital circuits
IPC: G06F11/277
Filed: 1979-08-16
Abstract: In order to avoid the need to design expensive test procedures a circuit under test 10 is tested against a perfect reference circuit 11 (which may be a computer model). Random digital inputs are applied to the two circuits from a pseudo random generator 12. Mis-matches between the outputs are detected by exclusive OR gates 13. The reference circuit is also constructed to provide inhibiting outputs when input bit patterns are such as to give rise to an indeterminate output. These inhibiting outputs inhibit the OR gate outputs at AND gates 14. Any OR gate output which is not inhibited leads to a fail signal at the output of an OR gate 15. <IMAGE>

Title: Pneumotachograph with Pitot- like Tubes
IPC: A61B5/087
Filed: 1980-05-29
Abstract: A pneumotachograph including a housing having first and second ports 23, 25 which, during the course of respiration, alternate as input and output ports and which provide a path 31 for generally linear flow of the respiratory gases. A pair of pitot tubes 33, 35 are disposed along the top of said path and are positioned generally at right angles thereto. A pair of baffles 41, 43 are disposed in the flow path to deflect the respiratory gases upwardly toward the pitot tubes but, since the pitot tubes are arranged above the baffles prevent heavier mucus, water and nongaseous materials from entering the pitot tubes. The baffles may be rigidly mounted or supported by resilient means to produce a linear output. Alternatively the baffles may be replaced by a single vertical baffle between the tubes, resulting in a pressure build-up upstream in proximity to the one tube and a venturi effect downstream for lower pressure in proximity to the other tube. <IMAGE>

Abstract: A circuit arrangement utilises pairs of diodes (D1a, D1b; D2a, D2b) for enabling simultaneous testing by means of a test push button (T) of independent AC circuits (S1, L1; S2, L2). Upon operation of the test push button (T), power is supplied to each of the independent AC circuits (S1, L1; S2, L2), via respective diode pairs (D1a, D1b; D2a, D2b), to operate each of the independent AC circuits (S1, L1; S2, L2) simultaneously, whilst in normal operation the diodes (D1a, D1b; D2a, D2b) ensure that the AC circuits are maintained independent from one another. The diode pairs may be replaced by a bridge arrangement (Figure 2). Similar diode pairs are utilised for electrically isolating forward and reverse inputs of capacitor split phase motors (M1, M2 in Figure 3) driven in parallel to prevent capacitor feedback overriding end of travel switches of each of the motors. <IMAGE>
