Title: Improvements in fasteners for conveyor belts
IPC: F16G3/02
Filed: 1944-01-13
Abstract: 574,192. Belt fastenings. BOWDEN, C. B., and BOND, W. J. Jan. 13, 1944. No. 666. [Class 80 (i)] A fastening device for power transmission and conveyer belts consists of five parts, viz. two plates 11 for attachment to the ends of the belt 12, two locking pins 13, one carried by each of the plates and a connecting link or group of links 15. The plates are bent to U- shape and secured by rivets 16. A locking pin 13 fits within the bend and each plate is formed with tongue pieces 17 to abut the ends of the belt and encircle the pins, and with bent-over portions 18 to retain the pin endwise. The pins are connected by the members 15 with part-spherical heads. The plates have slots 20 with a middle portion 21 of sufficient width to allow the heads to be inserted. The pins are formed with slots 23, corresponding in position with the slots in the plates, and of sufficient width to receive the stems of the members 15. Adjacent these slots are countersunk portions 24 for receiving the heads. The undersides 25 of the heads are of elongated parallel form to engage corresponding recesses 26 in the pins. The ends of the pins may have non-circular recesses 28 to receive a key to rotate the pins to the correct position. Disengagement may, however, be effected without the key. By moving the member 15, Fig. 2, anticlockwise, the pin 13 is partly rotated, the part 15 entering the upper part of slot 20. The parts 25, 26 are then disengaged and member 15 is returned to its position in alignment with the belt. A pull on the member 15 will further rotate the pin to the position shown in Fig. 3, whereby the fastening may be disengaged by withdrawing the head through the wide part 21 of the slot. In the case of coal-conveyer belts, movement of the heads dislodges coal dust.

Title: Dies for cutting external screw threads
IPC: B23G5/10
Filed: 1934-01-10
Abstract: 414,579. Screwing dies and dieheads. CROSS, E. J., 10, New Court, Lincoln's Inn Fields, London.-(Dardelet Threadlock Corporation ; 120, Broadway, Manhattan, New York, U.S.A.) Jan. 10, 1934, No. 964. [Class 83 (iii).] In a die-head for cutting external self-locking screwthreads of the " Dardelet " type, the cutting edges of the chasers are arranged as shown in Fig. 4. Each chaser has inclined and axial trueing surfaces T, F, and a preliminary cutting tooth R<1>-R<4>. The tooth R<1> is reduced at the sides and also in height, the tooth R<2> has the full width of the final thread groove but a height less than the tooth R', the tooth R<3> has a base width equal to that of the thread groove but is reduced at the sides, and the tooth R<4> has the full width of the thread groove but a height slightly less than the tooth R<3> and has a crest inclined to the thread axis at the same angle as the self-locking base of the final thread. Each chaser also has a number of following teeth R of the full thread contour, the crests having the same axial inclination as the tooth R<4>, and the root diameter B, B of all the teeth being constant. The first two teeth of each chaser are given the correct cutting angle by means of an inclined face C, Fig. 5, on the inner end thereof, the plane of the face C being parallel to the die-head axis. The non-cutting end face L of the remaining teeth R is inclined to the head axis so that the following teeth overlap the work more than the first ones, to assist the guiding action of these teeth. The cutting edges described may be applied to the tangential chasers of a pivoted-carrier diehead, as shown in Fig. 5, or to the radial chasers of the die-head shown in Fig. 9, wherein the radial chasers 25<a> are secured in a body 27, slotted at 27b, and adjusted by a split clamping ring 26.

Title: Emergency brake for a lift
Inventor: LAMB MILES P
IPC: F16D59/00
Filed: 1997-02-20
Abstract: A lift installation with car, counterweight, carrying ropes, driving pulley, motor, brake and catch device on the car has an additional emergency brake which acts directly on the driving pulley (1). This emergency brake is intended for emergency braking in the ascending direction, because the catch device cannot be used in this direction of travel for various reasons. A star-shaped brake element (5) located on the driving-pulley shaft (7) is permanently pressed against an annular end face (4) by a disc spring (6) and normally rotates with the driving-pulley shaft (7). In the event of overspeed in the ascending direction, a tripping apparatus (18) pushes a locking pin (11) between the spokes of the star-shaped brake element (5), locks the latter and thus produces with the brake plates bearing on the annular end face (4) a corresponding braking torque. The braking torque can be up to one order of magnitude higher than that which is produced with the normal operating brake.

Patent HK-76596-A (HK)
Title: Method and system for image coding and display
Inventor: RICHARDS NORMAN DENNIS
IPC: H04N1/41
Filed: 1996-05-02
Abstract: Pixel information representing an image for display is coded using data compression. The data compression consists in obtaining the pixel information as a first matrix of high resolution pixel values, subtracting from this first matrix a second matrix composed of lower resolution pixel values, produced by low pass filtering the first matrix, to produce a third matrix of difference values, sub-sampling the second matrix to produce a fourth matrix of less density lower resolution pixel values and coding the third and fourth matrices. Complementary decoding consists in restituting the second matrix by interpolation filtering the decoded fourth matrix, and combining the restituted second matrix with the decoded third matrix. Loss of accuracy in the decoding method is reduced by coding and then decoding the fourth matrix during the coding method before it is interpolated to full pixel density to form the restituted second matrix which is subtracted from the first matrix to produce the third matrix of difference values. In this way, any sub-sampling and interpolation errors in the restituted fourth matrix occur in both the coding method and the decoding method and therefore cancel out. Figure 3 illustrates the coding method including these coding and decoding steps.

Title: Monitoring method of welding
Inventor: SHIMIZU TAKEO
IPC: B23K9/10
Filed: 1984-01-06
Abstract: PURPOSE:To enable simultaneous monitoring of both of an arc and welding surface by reflecting the light of the arc of welding by using a mirror so as to irradiate the welding surface thereby decreasing the difference in luminance between the arc and the welding surface. CONSTITUTION:Light of an arc 2 generated by a welding rod 1 is reflected by using a mirror 7 to irradiate a welding surface (groove, pool, etc.) 3 thereby decreasing the difference in luminance between the arc 2 and the surface 3 and monitoring simultaneously both. An elliptical mirror is more particularly preferably used as the mirror 7 and the focus 7A thereof is made coincident with the center of the arc 2. The welding surface is regarded a plane mirror and the mirror 7 is disposed in such a way that the focus 7A' of the image 7' of the mirror 7 by said mirror coincides with the center of the incident pupil of an objective lens provided in an optical system 4 such as a fiber scope or the like connecting to a TV. The light reflected from the mirror 7 is thus made incident most effectively to the optical system 4 by which the difference in the luminance between the arc 2 and the surface 3 is decreased.

Abstract: PURPOSE: To detect a program getting out of control by latching a natural value in a register by a specific output instruction at a check point on a program and then by making a comparing decision on the propriety of a next check point.  
     CONSTITUTION: A parameter signal in bus signal 11 is supplied from decoder 13 to AND circuits 14 and 15 and while FF17 is set by output instruction pulse 16 as a 1st check point, a natural value of a check point of data signal 22 is latched by latch 21 by way of AND circuit 19. Further, timer 24 is actuated by the output of circuit 19. The output of FF17 closes circuit 19 through delay circuit 18 and the timer is  not actuated hereafter. The content of latch 21 is compared with data signal 22 by  comparator circuit 28 all the time and when a coincidence is detected, FF17 is  reset through gate 27 to restart timer 24. If a program gets out of control and no  check point is found, timer 24 generates a timer-out signal to inform through FF26  that the program is getting out of control.
