Abstract: The invention refers to a tape printing apparatus (2) used with tape cassettes (20, 220, 243, 260, 443). In order to make insertion and removal easier, the tape cassette is provided with a surface controlling the position of a printhead (22, 222, 322, 422) and/or a platen. When the cassette is inserted, printhead and platen are automatically separated such that the tape (24) can be introduced between them, and afterwards moved in the operative position. Further, an over center mechanism is proposed for moving printhead and platen. The tape cassette (443) can provide a 90.degree. bend in the tape (24) upstream the printing position, and the motor (42) can be located besides the zone for accommodating the image receiving tape (24). The cassette can be made attachable to other cassettes, and the means for attaching can guide and hold the cassette in the tape printer.

Abstract: Alkoxy-functional room temperature vulcanizing (RTV) compositions, curable in the presence of moisture, comprising polymers containing on average at least 1.2 alkoxysilyl chain terminations per molecule, a tetraalkoxytitanium compound containing on average greater than 90 mole percent of the alkoxy groups as tertiary amyloxy groups, a filler, and an alkoxysilane. The addition of these components in amounts to satisfy defined molar ratios provide alkoxy-functional RTV compositions having both improved storage stability and improved green strength upon curing.

Abstract: A tape printing device comprises a print head, means for causing relative movement between an image receiving tape and the print head, and control circuitry for controlling the print head. The print head has a set of selectively activable printing elements arranged along a longitudinal axis of the print head. The control circuitry prints each pixel by activating the same printing elements on successive print cycles to limit the peak current of the print head. Each group of printing elements lie at an acute angle with respect to a longitudinal axis of the print head to prevent staggering in the printed image. The tape printing device uses an arrangement of group switches and switches for individual printing elements to reduce the required number of switches which reduces the cost of the apparatus. Current is controlled to prevent accidental activation of printing elements to reduce the number of errors in the printed image.

Abstract: The present invention relates to a label printing method and apparatus which includes a housing providing a zone for receiving printing tape on which an image is to be printed, a data input device for inputting information defining the image to be printed as a label, a printing mechanism including a group of printing elements to which pixel data defining the image to be printed is passed sequentially on a group-by-group basis by a printhead controller and a motor operable to drive the printing tape past the printing mechanism.

Abstract: A printing device (2) for printing an image receiving medium has a printing mechanism and a keyboard (4) having a plurality of data entry keys (6) for entering data for controlling the printing mechanism and a user key (16). Storage means for holding data accessible in response to the data entered at the keyboard (4) is provided. A controller defines an image to be printed on an image receiving medium in dependence on the data accessed in response to the data entered at the keyboard (4) so that the controller operates selectively in one of a plurality of modes of operation. The modes of operation include a normal mode of operation in which at least some of the keys (6) have predetermined functions associated therewith to access predetermined data associated with the predetermined functions.

Abstract: A post assembly for attaching a worker safety harness to a structure comprises a post member having two transversely spaced wall attachment assemblies at its lower end and on opposite sides thereof and a roof attachment assembly intermediate its ends, the assemblies being releasable to enable the post assembly to be removed while the parts attached to the wall and roof remain for re-use. The assemblies have attachment axes that diverge toward the wall to increase the transverse spacing between the attachment points as the spacing from the wall increases. The spacing of the wall assemblies and their placement on opposite sides of the post ensures that part of any sideways acting force is converted from undesirable shear peeling force to compressive force on one wall assembly and tension force on the other assembly. The part of each attachment assembly that contacts a surface may comprise a central plate with one or more side and/or end plates hinged thereto to accommodate curvature of the roof surface.

Abstract: A composition curable to a silicone rubber exhibits adhesion to metal and glass substrates under both dry and wet conditions where the composition contains an alkenyl-containing polydiorganosiloxane, an organohydrogensiloxane, a hydrosilation catalyst containing platinum, an (epoxy-functional organo)trialkoxysilane, an alkoxy-silicon compound, and a titanium compound having Ti--O--CH bonds and the molar amount of alkoxy-silicon compound exceeds the molar amount of (epoxyfunctional organo)trialkoxysilane.

Abstract: The present invention provides a system for controlling heating and cooling equipment in an energy efficient manner. The system comprises a microcontroller, a temperature sensor, a motion detector, a telecommunications interface and a control interface for the heating and cooling equipment. The system can override the thermostat control of the heating and cooling equipment and operate the equipment at a first set-back level and a second set-back level. The system will operate at the first set-back level if there is no motion for a pre-determined period. The system will revert to thermostat control if motion is detected within a second pre-determined period, otherwise the system will initiate operation at the second set-back level. The system will operate at the second set-back level until motion is detected or a control signal is received from a telephone. If thermostat control is initiated by a telephone, then the system will disable operation at the first set-back level until motion is detected.

Abstract: A two part sealant cures rapidly in deep sections when the two parts are mixed together. A first part consists essentially of a hydroxyl endblocked polydiorganosiloxane, non-reinforcing, non-acidic filler, diacetamidosilane chain extender of the general formula ##STR1## and aminoxysilicone compound having from 1 to 100 silicone atoms per molecule and from 3 to 10 aminoxy groups per molecule. A second part consists essentially of a hydroxyl endblocked polydiorganosiloxane, non-reinforcing, non-acidic filler, and water. When mixed together, the two parts cure rapidly in deep sections.

Abstract: Liquid silicone compositions are described that cure to rubber which exhibits a unique combination of properties including low compression set and unprimed adhesion to a variety of substrates. The compositions include silicone polymers curable by hydrosilation reaction and specific combinations of adhesion promoting materials. Compositions containing aluminum chelates and epoxytrialkoxysilanes have been found particularly useful when adhesion to metal substrates is desired. When the compositions are desired to adhere to plastic materials, it is advantageous to include along with the aluminum chelate and epoxytrialkoxysilane, a tetraalkyltitanate, an alkylpolysilicate, and an acrylate or methacrylate compound.

Abstract: Defective repeaters in a multihop, digital microwave transmission system are located by the use of a special test pattern which is generated at the transmitting terminal. At each repeater station, the two outputs of the phase demodulator are compared to determine if the test pattern has been properly received from the upstream repeaters. The special test pattern, S, has the characteristic that S = S(2N); that is to say, the test pattern equals the complement of itself delayed by 2N symbols. This special characteristic makes it unnecessary to employ a differential decoder in the test apparatus at each repeater station.
