Patent EP-0265777-A2 (EP)
Inventor: TRICKETT ELIZABETH A
IPC: B32B18/00
Filed: 1987-10-14
Abstract: A method of preparing ceramic monolithic structures with an internal cavity and passageways is described. A thin sheet of a ceramic material is formed by spreading the material on a glass plate with a doctor blade. Individual sheets of the material are cut or punched to form predetermined holes (24), channels (23) or various shapes therein. These individual sheets (20, 21, 22) are then stacked to form a layered structure (10). A supporting media such as paraffin wax is injected into the holes and channels to completely fill them with the media. The layered structure (10) is then pressed by unipressing and/or isostatic pressing followed by a prefiring step to remove the supporting media. Once the supporting media had been completely removed, the layered structure is then sintered to form a monolithic structure containing precise predetermined internal cavity and passageways.

Abstract: A method for providing fault tolerant transmission of electrical signals through a transmission device (15). Together with an original signal (Aʹ), a number of redundant signals (Bʹ, Cʹ, Dʹ; or only Cʹ) are transmitted through a transmission device, wherein the number of redundant signals per original signal (Aʹ) varies dynamically in accordance with selected conditions (Q). These selected conditions are typical of whether the transmission device, typically a switching network, is in normal or in over flow operation. Putatively identical signals at corresponding outputs (4a, 4b, 4c, 4d; or only 4a, 4c) of the transmission device are then compared (10) and at least one correct output signal (a and/or b) is generated therefrom.

Abstract: The lid of a round or cornered household package can be constructed in a child-resistant manner independently of the presence of a carrying handle if it consists of a lid frame (1), which is fixedly connected to the container, and a lid sheet (10) which is to be placed loosely in said frame, and if the inside periphery (3) of the lid frame (1) is fitted at diametrically opposite points with a fixed holding rib (4) on one side and a resilient arresting web (5) on the other side, in each case above the closed position (9) of the lid sheet (10). Furthermore, the lid sheet (10) is provided on the inside periphery (3) of a resting edge (7) with a step (8) which allows the lid sheet (10) to rock, with the arresting web (5) neutralised, between an "OPEN" and a "CLOSED" position (Figure 1). <IMAGE>

Abstract: The sheet feeder can be mounted on a typewriter or on a printer in a system for processing data. The sheets (12) which are accommodated in a feed magazine (28) are passed to the platen roller (210) by friction stripper rollers (250). After the printing operation, the sheets are passed on to a collection table (150) positioned in front of the feed magazine. The stripper rollers are permanently connected to the platen roller by way of a mechanical transmission (212, 218, 226, 245, 248) and rotate in the same direction as the platen roller. The stripper rollers (250) are mounted on an oscillating arm (252) to be selectively moved towards or away from the first sheet to be fed, by means of a first cam (254). Before a fresh sheet is fed, a second cam, (242), also coupled to the platen roller, has to be brought to a reference position by rotating the platen roller enough to expel the current sheet. The platen roller is then rotated in the reverse direction, whereby the second cam actuates a lever (262), thereby to close a clutch (260). During subsequent rotation of the platen roller in the forward direction, the clutch rotates the first cam (254) through one revolution for engaging the stripper rollers (250) with the top sheet (12), thereby effecting stripping and feed of a sheet. At the end of the rotary movement through one revolution of the cam, the stripper rollers are moved away from the sheets and the clutch is opened, making the cams inoperative independently of subsequent rotary movements of the platen roller in one direction or the other.

Abstract: A compartmentalized transport refrigeration system, and method of operating same, in which a host refrigeration unit 14 controls the temperature of the air in a front compartment of a trailer, and a remote evapor­ator unit 24 controls the temperature of the air in a rear compartment. In order to increase the heating capacity of the remote evaporator 24, the host's hot gas line 66 is selectively controlled (G) to enable all of the hot gas from the compressor 28 to be directed to the remote evap­orator 24 when the host unit 14 is in null. The host unit 14 can only heat when the remote unit 24 is in null. In order to increase the cooling capacity of the remote unit 24, the host's liquid line 42 is selectively controlled (F) to enable the liquid from the receiver 40 to be all dir­ected to the remote evaporator unit 24 when the host unit 14 is in null.

Abstract: The invention relates, in general, to an identification code sheet (10) for representation of codes of a merchandise, a character string and a document etc. and a method of its reading. The identification code sheet (10) for identification of the merchandise etc., according to the invention, comprises a representation area (20) defined by both an X-axis (16) and a Y-axis (18) intersecting mutually either orthogonally or skewedly and sub-areas (24) of identification code (21) printed in said representation area (20). According to the invention, said representation area (20) is divided into sixteen or more sub-areas (24), in each of which an identification code (21) of signal codes (22) of binary type is recorded. In this manner, much more information relative to the same by conventional technique may be handled and more particularly much more Kana-Kanzi, Arabic and Chinese letters etc. as well as numerical characters, symbols, and alphabets may be represented with an improved ease with which they can be read. The representation of representation areas (20) defined by both the X-axis (16) and the Y-axis (18) and the identification code (21) in said sub-areas (24) ensures an improved accuracy and speed of reading by means of a senser to read the identification code sheet (10) in any direction and further a simpler reading, representation and outputting etc. by use of a printing sheet and printing means for general use.
