Abstract: In a line pressure control device of an automatic transmission for vehicle a circuit is provided for generating a target line pressure signal corresponding an actually measured load signal obtained from an engine load sensor. A line pressure sensor generates an actually measured line pressure signal corresponding to the line pressure. A converter converts the target line pressure signal and the actually measured line pressure signal into upper limit line pressure signals and lower limit line pressure signals which are set given amounts above and below the target signal and the actually measured signal respectively. A decision circuit compares the upper and lower limit line pressure signals drives and properly driving and controls the hydraulic pressure adjusting valve in accordance with the result of the comparison.

Abstract: An apparatus for monitoring the build-up of ice on engine and plant parts encompasses a monitoring surface area and a reference surface area located on a part of such engine. There is provided a first means which heats the reference surface area to a temperature above the freezing point. A second means illuminates the reference surface area as well as the monitoring surface area. The light reflected from both these areas is led to a light receiver which emits signals which are applied to a fourth means. This fourth means determines the difference between the output signals of the light receiver and generates accordingly a control signal. This apparatus allows a safe detection of ice build-up independent from a soiling of the monitoring and/or reference surface areas.

Abstract: This invention is directed to a high speed cold adhesive curing process and apparatus therefor, useful in the assembly and fastening together of fibrous surfaces such as the surfaces of corrugated Kraft paper cardboard boxes. The invention is directed to a process for adhering two fibrous surfaces together by means of a liquid cold cure adhesive comprising: (a) spraying liquid cold cure adhesive on the interface surface of one of the fibrous surfaces in a thin discrete particle pattern; and (b) pressing the two fibrous surfaces together under high pressure sufficient to cause the solvent carrier in the cold cure adhesive to disperse into the interstices of the fibres of the two surfaces, thereby enabling the cold cure adhesive particles to rapidly secure the two surfaces together.

Abstract: A cable car type vehicle arrester features a pair of trumpet bars which are interconnected by a link which either maintains the distance between the bars constant or reduces same upon one of the bars being deflected outboard of its home or rest position. This reduces the free swinging time of the vehicle between bars and increases the distance through which the bars subsequent to the initial deflection are deflectable by the vehicle. This accordingly increases the stroke of shock absorbers associated with the bars increasing the conversion of the kinetic energy of the vehicle. Casters can be provided to support the bars to allow longer lighter bars with less robust bearing and structural members. The casters can be run on a corrugated surface to cam the bars vertically further increasing the kinetic energy conversion and endow a self-centering action on the arrester.

Abstract: In a hinge device for tiltable windows, the base plate of the sash portion is provided with a pivot pin journalled in a guide member which is connected to the base plate of the frame portion in such a manner as to be mainly translatorily displaceable in relation thereto, whereby the pin during the initial opening movement of the window is moved downwards and outwards in relation to the frame portion. The sash portion of the hinge is also provided with a guide pin which by co-operation with guiding members on the frame portion co-ordinates the tilting movement of the sash portion about the pivot pin with the movement of displacement of the pin with a view to obtain a sash movement allowing outer covering elements to be arranged with an efficient overlapping relationship in the hinge area. By maximum displacement of the pivot pin the guide pin clears the guiding members so that the sash is free to tilt further in the opening direction while a stop prevents a rearward displacement of the guide member.
