Patent EP-0046058-A2 (EP)
Inventor: HALL ROBERT JAMES
IPC: G01N21/89
Filed: 1981-08-05
Abstract: In order to detect defects such as holes and inclusions in the manufacture of a longitudinally-moving web (10), for example paper, three cameras (22a, b and c) each containing a line array (24) of photo-diodes, are imaged transversely across respective portions of the web. Each array is repetitively scanned to sample the photo-diodes in turn. The photo-diode video signals are digitised and sequentially stored in a random address memory (52) that is addressed in synchronisation with the sampling of the photo-diodes. Arithmetic circuitry (56. 58) subtracts the fresh digital value from a given diode with the value for that diode from the previous scan and signals a defect if the difference exceeds set limits. Logic circuitry (60) controlled by the sign of the difference signals whether the defect is a hole or inclusion. The fresh value is then entered in the memory to serve as a reference for that diode on the next scan. There is also described circuitry responsive to hole signals from the camera viewing the middle portion of the web to indicate when there is no web or an irregular web, and counting and indicating circuitry for the holes and inclusions.

Abstract: A device for facilitating non-verbal communications between individuals. The device includes a two-sided panel containing a plurality of message blocks which are selectively illuminated by the individuals in a variety of modes. In a first mode, the message blocks are sequentially scanned in one of two patterns, with scan direction and termination being controlled by actuating a switch. In a second mode, a transparent, direct select keyboard is placed over the message blocks and individual message blocks are selected by touching the keyboard in front of the block to be selected. Finally, the position of the illuminated message block may be controlled by a joy stick. The message blocks on the panel are printed on removable overlays which are specially adapted for various situations. The overlays carry identifying markings which are automatically read by the device so that the messages on the overlay, which are stored in non-volatile memory, can be correlated to their position on the panel. The overlays include a number of special function blocks which, when selected, cause the device to operate a wheelchair, sound an audio alarm, communicate with a computer or other device through a serial I/O port, or communicate ultrasonically with external devices. Each message block may include several different messages, with the message selected in that block being designated by a corresponding level-selection block. The messages may be either letters or words, and the combination of letters and words may be accumulated in an alphanumeric display or a printer.

Abstract: A sensor array (12) provides a plurality of distinguishable bitmap images of a pattern (22) and comprises an array of sensor cells (20) capable of sensing radiation. The cells are connected in a manner to form distinguishable bitmap images of a contrasting pattern through a pattern of correspondence among the cells. Each bitmap image formed comprises a combination of one or more cells which have responded to the incidence of radiation within a field of array cells that have either not responded or been inhibited from responding. The pattern of correspondence may be one of inhibition or of response of sensors. The patterns of correspondence create bitmap images. The variations between successive bitmap images give a measure of the direction and amount of movement of the sensory array relative to the pattern, which can be used to control the movement of a cursor over a computer display screen.

Abstract: An improved slip-type elevator locking mechanism has a lock rod which has one end connected to the slipsetting yoke and a free end extending generally parallel with the direction of movement of the slips in the elevator bowl. A cam arm mounted on the elevator at a central pivot point has a cam throat on one end which is adapted to receive the lock rod free end and an opposite end and is pivotable about the central pivot point between upper and lower lock rod engaging positions and a neutral, unlocked position. A fluid cylinder is pivotally mounted by a base end to the elevator and is pivotally attached at its output shaft to the cam arm opposite end for urging the cam arm to the neutral position. The fluid cylinder output shaft is spring-biased outwardly away from the base end in the absence of fluid pressure on the cylinder. A yoke rod has one end connected to the slip-setting yoke and a free end extending in a direction generally parallel to the lock rod in a plane which intersects the plane of the cam arm opposite end. Upper and lower coil springs on the yoke rod urge the cam arm toward a select one of the upper and lower lock rod engaging positions when fluid pressure is lost.

Abstract: The invention relates to rock drilling equipment particu- lady of the down-the-hole type. More particularly the invention relates to such drills incorporating a flap valve. Hitherto such drills have been designed to operate at a particular air pressure with the disadvantage that if on a particular site the compressed air availability does not suit the drill, its effectiveness is impaired. It is equally the case that conventional rock drills of the type in question operate at a relatively low cutting speed calculated on a feet per minute basis. The object of the invention is to provide a rock drill capable of considerably higher cutting speeds than has hitherto been possible and which is capable of operation over a range of air pressures. The objective is met by a construction comprising a backhead for the connection of a drill to a source of compressed air, a wear sleeve secured to the backhead and a chuck adapted to retain a drill bit secured to the opposite end of the wear sleeve, there being within the wear sleeve an inner cylinder with a valve seat at one (inner) end of the cylinder having a valve stem extending into the cylinder and a piston within the cylinder reciprocable therein from one position where the valve stem engages in a bore in the piston to a second position where a stem on the piston enters a bearing located in the cylinder and strikes a drill bit held within the chuck, the dimensions of the piston being such that the ratio of the piston head diameter to its bore diameter is in the range 9.9/9.95 to 1, the ratio of the piston head length to the piston stem length is in the range 1.5/1.52 to 1, the ratio of the piston head diameter to the piston stem diameter is in the range 1.4/1.43 to 1 and the ratio of the piston stem length to the length of the piston stem within the bearing at the point at which the piston strikes the drill bit is 1.4/1.45 to 1. It is further highly desirable that the rock drill has a valve seat wherein the ratio of the cross-sectional area of the part of the valve seat within the cylinder to the cross-sectional area of the stem of the valve seat is in the range 0.09/0.10 to 1, the ratio of the stroke length of the piston to the length of the stem of the valve seat is 0.87/0.88 to 1 and the ratio of the net internal length of the bearing to the stroke length of the piston is in the range 0.56/0.57 to 1.

Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk, and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. For the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming device pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations. 
     The abovementioned forming principle works less well if the packing containers are not completely filled, but have a certain air space, so-called headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome in that a sealed off part of the packing material tube is pressurized with the help of gas during the forming process, so that the internal back pressure required during the forming is obtained, independently of the quantity of contents. The method also permits an accurate proportioning of the contents either by continuous feed at a controlled flow rate or by discontinuous feeding in portions. The invention also relates to an arrangement for the realization of the method.

Abstract: An anti-skid control systemtakes a procedure for sampling input time data of every given number of sensor signals, which given number is adjusted so as to a difference of period of time measured with respect to mutually adjacent signal-to-signal intervals is great enough to perform the anti-skid control operation based thereupon. The anti-skid control system processes sampling operation as a job to be performed by interrupting main job for deriving control signal for increasing, decreasing or holding the fluid pressure to be applied to the wheel cylinder. The occurrences of interruption are counted up whenever it occurs and counted down upon each cycle of main job is completed. The job for sampling the input time data is performed at each time of inputting of the every given number of sensor signals. When the difference of period of time of the adjacent signal-to-signal intervals is less than the predetermined value, then, the number of sensor signals to be thinned without sampling the corresponding input time data is increased until the difference become greater than the predetermined value.
