Abstract: A method for the manufacture of a mould intended for the precision moulding of glass articles, notably aspherical lenses. The desired shape and dimensional accuracy are imparted to a mechanically treated preform by an accurate polishing operation. Subsequently, the polished preform is prestressed and reinforced by a chemothermal treatment. The surface of the mould thus obtained comprises an edge zone which is subject to compressive stress and which changes over, via a neutral stress-free zone, to the core which is subject to tensile stress. The mould in accordance with the invention has a longer life and produces moulded products having a quality which is higher than that of products made by means of known moulds.

Abstract: In a gaseous fuel carburetion system in which air and gaseous fuel are mixed in a mixer prior to induction into an internal combustion engine, and in which the rate of flow of the induction air is controlled by throttling the intake of the air/fuel mixture, and in which gaseous fuel is supplied to the system from a pressurized source, an improved method and apparatus for regulating the supply of gaseous fuel to the air/fuel mixer is provided. The method comprises the steps of; sensing at least one operating parameter of the engine which is a function of the induction air flow rate and generating a control signal which varies in response to changes in the induction air flow rate, controlling the rate of flow of the gaseous fuel from the source to the mixer by means of said control signal whereby the rate of flow of the gaseous fuel varies in response to the sensed changes in the parameters related to the air flow rate. The apparatus comprises; mixer means arranged to receive and mix the induction air and the gaseous fuel supply and to deliver the mixture to the engine, sensing means (S 1 ....S 3 ) for monitoring at least one operating parameter of the engine which is a function of the induction air flow rate and generating a control signal which varies in response to changes in the induction air flow rate, flow control means (20) adapted to control the rate of flow of the gaseous fuel from the source to the mixer whereby the rate of flow of the gaseous fuel varies in response to the sensed changes in the parameters related to the air flow rate.

Abstract: α- There have been many approaches to the storage of representations of characters in a computer but no really satisfactory solution exists for storing the very large number of Chinese characters which are in use. 
     According to the invention the strokes of the characters are classified into regular strokes including horizontal, vertical and turn strokes mainly composed of straight segments, and irregular strokes in the form of curves, and different compressed representations are used respectively:
     for regular strokes, a 24 to 48 bits compressed representation is used to describe the beginning X, Y coordinates, length, width, starting feature, ending feature turning feature and slant, and   for irregular strokes, e.g. of Chinese characters and characters of other languages, a series of vectors (approximately straight segments) are used to approximate to its curved contour with each vector represented by directed increments of X, Y coordinates and a number of different cases of increments are discriminated to make the representation more compact.   
     Such an arrangement provides compact storage particularly since it is possible to scale the stored representation to provide from a single basic size any other desired size. 
     The representation can be transformed into a dot matrix which is in turn used to form a page layout to provide input for a laser typesetting system.

Abstract: A card frame for housing electrical circuitry mounted on cards comprises end plates (10) separated by front and rear cross rails (12, 14) that mount card-guides (16) in which the cards can slide. Each card guide (16) comprises end elements (28a, 28b) engageable with the front and rear cross rails (12, 14) in first and second positions (Fig. 1 and Fig. 2) spaced in both the top-to-bottom and front-to-rear directions of the card frame.

Title: Gravity feed chute

IPC: B65G11/02
Filed: 1982-11-30
Abstract: A chute for gravity feeding a plurality of like electrical components (1) to a pick-up station of a robotic controlled automatic assembly system comprises guide rails (2, 3) down which components slide with their pins (13) extending between the rails. The rails are shaped to provide a downwardly inclined straight track (5) leading into a horizontal track (6) comprising the pick-up station from which the components are taken by the robot. The transition from the inclined track (approx. 30 degrees to the horizontal) to the straight track, although smooth, is quite abrupt and ensures that the next component is successfully fed from the inclined to the horizontal section of the chute each time its predecessor is removed from the pick-up station. Since the length of the horizontal track is such that only one component can be accommodated at a time, accurate positioning of the component in the pick-up station for access by the robot is guaranteed.
