Abstract: 649,801. Vehicle fittings for unloading. WALTERS, K. M. Nov. 23, 1948, No. 30357. [Class 78 (iv)] [Also in Group I] A manure distributer, of the type having an endless slot-conveyer 7 feeding manure through an aperture 13 in the rear end of a container 3, is characterized in that the upper run of the conveyer moves the material forwardly to an aperture 5 in the floor of the container where it falls through on to a platform 14 and is fed to the aperture 13 by the return run. By this means, the rear part of the container is emptied first. The material then falls on to spreading devices (not shown).

Title: Automatic yarn feed rate control system for warp knitting machines
IPC: D04B27/22
Filed: 1974-07-09
Abstract: 1429605 Knitting-machines LIBERTY FABRICS OF NEW YORK INC 9 July 1974 [10 Dec 1973] 30392/74 Heading D1C An automatic yarn feed rate control system in a warp machine comprises a first generator responsive to the machine speed, and a second generator coupled to the first and the warp beam drive, responsive to the instantaneous beam diameter. The first generator comprises a slotted disc driven from the crank shaft and sensed with a light source and photosensitive transistor. The number of pulses in the output is proportional to the crank shaft revolutions and is multiplied by a first multiplier. A second multiplier, set by switches, sets the required yarn length per rack as a fraction of a maximum yarn runner length The output from the second multiplier is fed to the second generator which comprises a series of countdown counters. The first counter multiplies the incoming pulses by a specific factor inversely proportional to the instantaneous warp diameter. Switches on a second counter set the initial value on the first. A third counter adjusts the first counter downwards progressively. It is preset to count down the output from the first and adjust the first by one digit after the appropriate count. It then resets. The specific fraction and count set initially depend on the yarn runner length and the initial warp diameter.

Abstract: 607,135. Luminescent screens. PALMER, A. J., and HAZLEHURST, A. N. Nov. 16, 1945, No. 30746. [Class 39 (i)] A luminescent screen is made by settling from a suspension of the phosphor in a medium in which potassium or sodium silicate is present in solution. In the example, zinc borate is precipitated by mixing sodium borate and zinc nitrate, filtering, drying and powdering, and it is then added to distilled water in the tube to be treated, the powder being allowed to settle and form a layer of zinc borate. The phosphor. e.g. zinc cadmium sulphide, and potassium silicate are made up into a suspension and introduced into the tube through a funnel terminating in four symmetrically placed holes which direct the liquid upwardly and outwardly. After settling for 2-3 hours, the supernatant liquid is poured or siphoned off and the screen dried. Boric acid may be introduced into the tube and allowed to dry and form a protecting layer over the luminescent screen. Specifications 502,919 and 591,506 are referred to.

[Also in Divisions F2 and H2]  An air bearing, having two relatively rotatable parts, has magnetic means for limiting radial relative movement other than between said parts. In an embodiment, a spinning-head 10 of a false  twist crimping apparatus for yarn, has a slot 11 which receives a pin 12 therein. An extension 13 of the head 10, is held in a hole in the bottom of a cup-shaped member 15 which has a flange 16 and is encircled by a hysteresis ring 17 or by a steel annulus 18, Fig. 4 (not shown); the inner and outer peripheries of the annulus being encircled by copper rings 19, 20 and its underface having helical grooves 21 therein which intersect the edges of the copper rings 19, 20 and have copper conductors 22 therein. The head 10 has an axial bore 9 therein and the assembly forms a rotor. The stator comprises a laminated annulus 23 of soft iron, has a conical hole 24 and eight slots 25 therein having two pairs of coils 28, 28<SP>1</SP> and 29, 29<SP>1</SP> therein, Fig. 2 (not shown). The coils are connected to two phase source of A.C. supply 6. The hole 24 has a tapered laminated plug 30 secured therein, the plug 30 having slots 47 therein which register with the slots 25 of the annulus 23. The plug is bonded to an insulating sleeve 31 which is also bonded to a member 32 having an air chamber therein. The bottom wall 33 of the member 32 has a magnetic core 34 fixed therein having an axial passage 35 and passages 39 therein. The core 34 may be a permanent magnet or may be a mild steel rod surrounded by a magnetizing coil 40 which is positioned, with plenty of clearance so as to not prevent air flow, in an annular chamber 38 formed by the member 32 and the core 34. Electric conductors 41 lead from the coil 40 to a D.C. supply 7. A disc 42 of non-magnetic material, has equi-spaced holes 43 which connect to an annular channel 44 therein and is mounted above the annular air chamber 38. The axes of the holes 43 may be inclined and the underface of the bottom 14 of the member 15 may be grooved so as to facilitate the rotation of the rotor. The rotor is centralised by the magnetic field which also tends to draw the rotor towards the stator, and is retained by a cover-plate 45. In use, the yarn 48 leaves the bobbin 51, passes through a tensioning device 49 through rollers 52 and a heater 50 then through the passage 35 in the core 34, where it is cooled by air supplied to the passage 35 via the passages 39, the annular chamber 38 and a pipe 37 which is connected to a pressurised-air source 8. Pressurised air also passes from the annular chamber 38, through the holes 43 and into the channel 44 in the disc 42 so as to  cause the rotor to "float" above the stator.

Title: Data processor
IPC: G06F17/14
Filed: 1971-07-05
Abstract: 1330741 Digital computers; fast Fourier transforms INTERNATIONAL BUSINESS MACHINES CORP 5 July 1971 [6 July 1970] 31352/71 Heading G4A A special purpose digital computer is used to evaluate fast Fourier transforms using the Cooley-Tukey algorithm (decimation in time) or the Sande-Tukey algorithm (decimation in frequency), e.g. for digital spectral analysis, filter simulation &c. The fast Fourier transform FFT is a method of computing the discrete Fourier transform DFT of a time series by sequentially combining progressively larger weighted sums of data samples so as to produce DFT's as defined by: where An is the n'th coefficient of the DFT and is almost always complex, Xj is a complex number, and W = e<SP>-2#i/n</SP>. The DFT's of the individual data samples are combined such that the occurrence times of these samples are taken into account sequentially and applied to the DFT'S of progressively larger mutually exclusive subgroups of data samples which are combined to produce the DFT of the complete series of samples. This method is stated to cause a reduction in computing time over the prior art methods. The Cooley-Tukey and Sande-Tukey algorithms are both described in detail and both require ¢N log N complex additions, subtractions and multiplications. If the prime factor corresponding to a given summation being evaluated for each of the N equations is #, then the FFT algorithm for the radix # evaluates this summation in # of the N equations at a time, hereafter termed # tuples, until this summation has been evaluated in all of the N equations. Each summation for all equations is called a stage of the FFT algorithm and since there are r nested summations in each of the N equations there are r stages. Each of the # summations in a # tuple consists of # terms containing a complex input value multiplied by a complex exponential. These # summations of # terms are called the kernal equations for radix #. # may have values 2 and 4 and the Cooley- Tukey or Sande-Tukey algorithms may be performed in radix 2, radix 2 + 4, or 4 + 2 (Figs. 6 to 13, not shown). The system.-The computation is effected by an array processor 10 (Fig. 2, not shown) connected to main storage 12 and a central processor 11. The latter may be connected to input/output units via a multiplexer. The array processor 10 accepts 1/0 instructions from processor 11 and performs its operations on data in main storage 12. It performs address indexing and counting operations, issues fetch and store requests for the input and result data, converts fixed to floating point formats and vice versa, interrupts processor 10, and performs arithmetic operations in floating point format using its own arithmetic unit. Two independent read only microprograms control the arithmetic unit and other sections of the processor 10 respectively. The arithmetic section performs the function U x X Œ Y where U is the multiplicand, X is the multiplier and Y is the augend.
