Title: Display system
IPC: G02F1/133
Filed: 1966-06-08
Abstract: 1,120,093. Light modulators. WESTING- HOUSE ELECTRIC CORP. 8 June, 1966 [29 June, 1965], No. 25455/66. Heading H4F. [Also in Division H1] A light control element in a display system comprises a cholesteric phase liquid crystal film which exhibits a change in its optical properties in response to temperature changes. The optical properties of the cholesteric liquid crystal film utilized in the embodiments described are optical activity, circular dichroism and selective scattering, i.e. reflection. In a first embodiment, Fig. 1, the light control element 15 comprises a liquid crystal film 21 in good thermal contact with a layer 17 exhibiting the property of absorbing modulated ultra-violet radiation from a cathode-ray tube 27 and converting the radiation image into a heat image. The light control element is positioned between a polarizer 11 and an analyzer 13 and as the temperature of the liquid crystal film is changed it rotates the plane of polarization of input monochromatic light beam 35 varying amounts and thus an information image is formed on screen 41. Layer 17 may comprise tartrazine, anthracene or phenanthrene which do not absorb the radiation from source 35. Alternatively, layer 17 may comprise nickel which absorbs about half of the incident radiation from source 35 and tube 27 and transmits a quarter of the remaining. The circular dichroic properties, i.e. the selective scattering of right- or left-hand circularly polarized light, of the film may be used by removing polarizer 11 and analyzer 13 and positioning a circular polarizer between light source 35 and control element 15, the polarizer and the film being of the same polarization, i.e. right- or left-hand. Source 35 need not be monochromatic and depending on the temperature of the film 21 the transmission properties of the polarizer, analyzer and control element vary due to the circular dichroism effect within the optical activity range of the material of the film, Fig. 4, not shown. Three separate systems may be employed using red, green and blue radiation sources to produce a sequential or simultaneous high intensity colour television image. In a second embodiment, Fig. 2, not shown, the control element is formed within a cathoderay tube and the heat image is produced by bombarding the control element with a modulated electron beam. To increase the speed of response the inner surface of the tube is coated with a plastic film, the heat conductivity of which reduces the thermal time constant of the system. In a third embodiment, utilizing the reflection, i.e. selective scattering, properties of the cholesteric liquid crystal film, the control element is formed on the inner surface of the face plate of a cathode-ray tube, Fig. 5, not shown. The control element is provided with a light-absorbing black coating adjacent the liquid crystal film so that light from a white light source is reflected, the colour of the reflected light depending on the temperature of the liquid crystal film, i.e. on the intensity of the video signal which modulates the electron beam.

Title: Testing integrated circuits
IPC: G01R31/28
Filed: 1973-05-30
Abstract: 1421936 Testing test patterns for integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 30 May 1973 [12 June 1972] 25827/73 Heading G4A To test whether a given series of patterns of N-state (e.g. binary) signals is acceptable for testing a given integrated circuit when applied to the circuit, the patterns are converted to patterns comprising (N + 1) state signals, the extra state corresponding to an indeterminate state such as is produced by race conditions in a sequential circuit, the (N+1) level patterns are applied to a simulation of the circuit having no faults and to a number of simulations each having one of the faults which the series of patterns is to detect, the number of outputs from the " faulty " simulations which include only signals in the N-states and which differ from the corresponding signals in the output of the " fault free " simulation when the latter includes only signals in the N-states are counted M fail  and the number of outputs from the "faulty" simulations which include one or more signals in the indeterminate state when the " fault free " simulation outputs include only signals in the N-states are counted M x . Any "faulty" simulation contributing to the count M fail  receives no further test patterns and any " faulty " simulation contributing to the count M fail  after a previous contribution to M x  causes the count M x  to be decremented.  The simulations may be in hardware or software forms and the original test patternsmay be generated by pseudo-random number generation, see USA Specification 3,633,100. As described a counter is preset to the total number of test patterns to be tested and decremented as each pattern is tested. The first pattern is applied to all the simulations and if the outputs from the " fault free " simulation are all definite and any of the " faulty " simulation outputs include an indeterminate level signal then the count M x  is incremented accordingly and the corresponding simulations are added to a pseudo-fail list unless they are already on the list whereupon no action is taken. The remaining " faulty " simulation outputs are then compared with the " fault free " simulation output, any " non-compares " causing count M fail  to be incremented and the corresponding simulation removed from comparison during the application of further patterns, since the fault represented has been proved to be detectable. If any simulation contributing to M fail  had previously been entered on the pseudo-fail list it is removed and M x  decremented since a more positive fault detection now exists.

[Class 78 (ii)] In a system in which one of a number of lifts is selected to answer a call, a verbal announcement of the lift to be used is made. The lift may be selected in a manner described in Specification 456,191 and when the selection is completed one of the lines 1-4 depending on the lift selected, is marked to light one of the lamps such as LA whilst wipers FS7, 8 connect the amplifier AM to a loud speaker on the appropriate floor. The message to be given is inscribed on one of the tracks SA-SD so that the output of cell LC is varied in accordance with the appropriate message, the output normally being short-circuited by contact bp3. As the beginning of the message is about to influence the cell segment TA is wiped by its brush so that relay BP energizes and locks. Contact bp3 opens and the message passes over wipers FS7 and 8 and is reproduced by the loud-speaker. When the message is finished segment TB is effective to energize relay EP so that relay BP is released to prevent further announcement. Relay EP also initiates the release of the apparatus so that another call can be allotted.

IPC: B02B1/00
Filed: 1953-09-22
Abstract: In producing puffed ready-to-eat maize grits by a modification of the method of puffing disclosed in the parent Specification, maize grits are freed from air, air is replaced by steam, the grits are cooked in steam at super-atmospheric pressure and then suddenly subjected to a low sub-atmospheric pressure, e.g. an absolute pressure below 8 inches of mercury.  At this stage, a volatile liquid, e.g. water, containing flavouring or nutritive substances, e.g. salt, sugar and vitamins, may be introduced to form a fine mist which penetrates the puffed grits.  The grits may be cooked for 1 to 11 minutes in steam at a pressure between 60 and 100 lb. per sq. in.  The puffed maize grits may be dried under sub-atmospheric pressure and may be heated during drying.  They may be cooled, e.g. to between 150 DEG  and 50 DEG F., and cold-set, before being brought under atmospheric pressure.  The absolute pressure at the start of puffing may be about 0,2 inches of mercury and may rise during puffing to 4 inches.
