Title: Improvements in or relating to Punching, Eyeletting, Lacing-hook-setting or analogous Machines.
IPC: A43D100/02
Filed: 1917-09-20
Abstract: 119,093. Gouldbourn, J., and British United Shoe Machinery Co. Sept. 20, 1917. Eyeleting; lacing-fastenings.-In a machine for setting eyelets, lacing-hooks, &c., a single operation of a treadle or knee-lever actuates driving means for two toothed members so as to operate them conjointly, or independently if only one member is free to move, one of the toothed members serving to control the spacing between the punching points by effecting the bodily displacement of the point of connexion between two links without changing its position relatively to the links, and the other toothed member serving to control the supply of eyelets to the setting-die; the invention is shown as applied to the apparatus described in Specification 720<B>/07; Specifications 18530/99, 720/07, and 720<A>/07 also are referred to. The driving means comprises a pinion 25, which is mounted in a rod 29 pivoted to a spring- controlled lever 31 connected to a treadle 39, and engages toothed members 9 and 23. The curved rack 23 is carried by a lever 21 having a pin-andslot connexion with the finger M<1>, the position of which, as described in Specification 720<B>/07, determines whether the nipple pin carried by the setting-die and serving to pick up an eyelet shall be operative or inoperative. The toothed sector 9 is connected by a link 5, Fig. 2, to the point of connexion of a pair of links 1, 3, which connect the cam-actuated lever K described in Specification 720<B>/07 with the punch-frame B<1>, the sector 9 being secured to a spindle 11 carrying a radial arm 15 working between pins 19 secured in holes in a fixed plate 17. On depressing the treadle against the action of a spring 41, the pinion 25 is moved bodily, carrying with it the toothed sector 9 and curved rack 23, thereby adjusting the space between the punching points and withdrawing the finger M<1> from the path of the nipple pin; if one toothed member is locked against movement, the pinion rolls on that member and effects the movement of the other. The finger M<1> may be locked in either the operative or inoperative position by a locking-bolt 43 controlled by an eccentrie stud 45.

Title: Optical apparatus for determining correlation or convolution functions
IPC: G02B27/46
Filed: 1965-03-31
Abstract: 1,029,929. Optical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 31, 1965 [April 13, 1964], No. 13611/65. Heading G2J. [Also in Division G4]. In values of correlation or convolution functions of two patterns for relative displacements along a given line are found by projecting one pattern 12 on to the other 14 as a continum of images displaced along the given line, each image being of a different light frequency, the light passing through the second pattern being collected at a point to represent the sum of the values of the desired functions. Light source 10 and lens 11 produce collimated light which passes through the transparency pattern 12 and the resulting image is broken up into a series of images by a spectroscope 13 comprising lenses 13A, 13B and prism 13C. The continum of images falls on transparency pattern 14 and the light transmitted is gathered by a coverging light guide 15E into a point 15C. This is spread into a line 15D by part 15B, and the image of this line at each frequency is projected by spectroscope 17 onto screen 18 as a series of lines of varying intensity. Each line image represents the value of the correlation function for the corresponding displacement. If the pattern 14 is rotated through 180 degrees the values represent the convolution function instead of the correlation function. Values for displacements along a plurality of lines can be obtained by moving pattern 12 and screen 18 in the y direction and providing a time integrating device, e.g. a phosphor coating, at screen 18. In the form of Fig. 2 (not shown) the values of the autoconvolution function are found by causing the image of pattern 212 to be passed through prism 227 and reflected back as a continum of images onto the pattern 212. Light passing through is reflected by a half-mirror 225 into collector 215 as before. The autocorrelation values may be derived by a similar system (Fig. 3, not shown) in which the image is caused to be inverted by a pair of lenses so that the inversion produced by the spectroscope is cancelled.

Abstract: 678,870. Controlling textile machinery by radio-activity. T.M.M. (RESEARCH), Ltd., GREENWOOD, F. A., RILEY, J. H., and ROBINSON, F. C. May 24, 1951 [June 2, 1950], No. 13838/50. Class 40 (iii). [Also in Groups IX and XXXV] In a machine operating on a continuously-fed mass of textile material the density at a point is detected by a source of Beta particles and an ionization chamber situated on opposite sides of the mass, the potential developed in the ionization chamber being used to control some operation on the mass. As shown, in a scutcher lap machine a web of material A passes from a feed lattice 10 past a rotary bush or stripper 11, a beater 14, a pair of collecting cages 15, 16, feed-rollers 17, 18, between the source of Beta rays 26 and the ionization chamber, over a stack of calender rolls 19-21, and is wound on to a roller in the form of a lap 25. The potential developed across ionization chamber 27 is amplified in a unit 28 and used to control the speed and direction of a servomotor 32 feeding a differential 33 also fed by the driving motor 34 of the feed lattice 10, thereby controlling the rate of feed of material to the beater 14. In a modification, Fig. 1 (not shown), the Beta ray source and ionization chamber are situated in front of the beater to control a servomotor feeding a differential gear coupling a motor to the dampers which control the airflow to the collecting cages 15, 16. An indication of thickness may also be derived from the gauge. Circuit (Fig. 1).-The voltage developed across the ionization chamber is fed to one grid of one valve of a cathode-coupled pair V1, V2, the other grid of which drives a first potential from a potentiometer P. The voltages developed at the anode of the two valves are fed respectively to one of a pair of pentodes V3, V4, each anode of which is coupled to the H.T. supply through half the field winding of the servomotor 29. The servomotor is coupled to a tachometer generator T producing a rate voltage which is fed to the suppressor grids of these valves. Potentiometer P is adjusted for the desired textile thickness, variations each side of this value causing the servomotor to run in one direction or the other.

IPC: G06G7/161
Filed: 1968-03-22
Abstract: 1,236,953. Angle of attack computer. SPERRY RAND Ltd. 24 March, 1969 [22 March, 1968], No. 13878/68. Heading G4G. The flight-path angle (angle of attack) of an aircraft is derived by measuring components of the aircraft instantaneous velocity in two mutually orthogonal directions in a vertical plane and computing the quotient of the velocities. The axis A of the aircraft lies at an angle α (angle of attack) to the flight path P and at an angle #<SP>1</SP> to the horizon H. A Doppler antenna 11 yields signals V L  and V N  representing the velocities in an arbitrary direction D and at right-angles thereto. Since the resultant of V L  and V N  must lie in the direction P, we have # = tan<SP>-1</SP>V N /VL, whence by geometry, α = ## - tan-<SP>1</SP>V N /V L . If the Doppler antenna is aligned with the aircraft axis A, #D becomes zero. Further, for small angles α, α= V N /V L . The signals V L  and V N  may be in the form of square pulses of constant amplitude and frequency f proportional to velocity, the frequency of V L  being much greater than that of V N . Division may be performed by a gate operating at frequency # N  which allows passage to the first complete cycle of # L  at each operating cycle. The resultant signal is a rectangular wave of constant amplitude having a pulse width inversely proportional to # L  and a recurrence frequency proportional to # N . The wave has a mean amplitude proportional to # N /# L . A correction for # D  is applied to the signal which is then fed to an indicating instrument.

Abstract: 1472177 Dough brake BURGESS ENG (STOKE-ON-TRENT) Ltd 14 April 1975 [29 March 1974] 13969/74 Heading B5A A dough brake comprises two reversible conveyers 17, 18 for passing a sheet of dough back and forth through a pair of driven rollers 10, 11 with the receiving conveyer being driven faster than the feeding conveyer and with the same feed and receiving speeds being used on each pass, and means for detecting when the sheet of dough clears the rollers, connected to a control means for reducing the roller gap at the end of each pass by one of a series of predetermined steps, the speed of the conveyers being arranged to suit the speed at which the rollers 10, 11 take in the sheet and then discharge it after it has been thinned. The conveyers 17, 18 are driven by motors 25 and plates 21 bridge the gap between them and the conveyers. A light source 23 and a photo-cell 24 are mounted below and above an aperture 22 in each plate 21 to detect when the dough sheet clears the plate. Roller 11 is driven through an articulated chain drive 28 from roller 10 and is mounted in yokes 13 which are vertically movable by rotation of lead screws 29 by a motor 33 acting through bevel gears 30 at each end of its drive shaft 31. When a photo-cell indicates that the sheet is clear of the rollers, they and the conveyers are stopped, and the motor 33 is energized to lower the upper roller 11. The motor 33 also drives a control member 34 via a chain drive 37 and a second shaft 36 until one of a series of elements 38 mounted alternately on opposite sides of the member 34 contacts one of the switches 39, 40. This stops the motor 33 and starts the rollers and the conveyers in the opposite direction. After thirteen passes a switch 44 is actuated by a further control member 41 to start a timer and to override the photocell signal and allow the conveyers to continue to run and thereby discharge the sheet to another station. After a timed interval the motor 33 is reversed to return the roller 11 and the control member 34 to their original positions, which condition is detected by the operation of a switch 45 by a further control member 42. A warning may be given of the commencement of the last pass so that the feeding conveyer can be manually slowed or stopped to smooth out any wrinkles in the sheet. The control member 34 is adjustably mounted on the shaft 36 for varying the final thickness of the sheet of dough.
