Title: Artificial reverberation apparatus
IPC: G10K15/10
Filed: 1961-09-14
Abstract: 1,001,518. Reverberation systems; stereophonic systems. WESTERN ELECTRIC CO. Inc. Sept. 14, 1961 [Sept. 29, 1960], No. 33046/61. Heading H4R. Artificial reverberation apparatus comprises, connected between a signal input for electrical signals representative of sound and a signal output, at least one all-pass network comprising a path including means 31 (Fig. 3a) for producing fractional gain, delay means 33 connected parallel to the means 31 and means 34 producing fractional gain and connected to feedback signals from the output to the input of the delay means 33. Output signals are obtained having substantially no attenuation of any frequency relative to other frequencies in the bandwidth of the input signals. A portion of an input signal is applied to an amplifier 31 of gain (- g) less than unity while the remainder is passed by an addition network 35 to a delay device 33. A portion of the output from the delay device is applied through an amplifier of gain (1 - g<SP>2</SP>) to an addition network 32 where it is added to the signal from amplifier 31. The remainder is fed back through amplifier 34 of gain (+ g) to be passed through the delay device 33 again. The gain g is 0À7 and the gain of the apparatus as a whole is unity for all frequencies. Several such apparatuses may be connected in tandem (Fig. 4, not shown) in which case the delays of the delay devices are such that the delay of one of them is equal to the overall reverberation time required and the delays of the others form a geometrically diminishing sequence. One or more such apparatuses 55 (Fig. 5) may be connected with " comb filter networks " 51, 52, 53 each consisting of a delay device 21 (Fig. 2a) and a feedback loop 22 of gain (+ g) less than unity. Quasi-stereophonic apparatus.-Two output signals are derived from a single input signal by two artificial reverberation apparatuses each comprising a delay device 61 or 61<SP>1</SP> (Fig. 6) and a feedback loop 62 or 62<SP>1</SP>. An undelayed path 63 or 63<SP>1</SP> is provided in each apparatus. For the apparatus with positive feedback loop 62 a difference output signal is obtained in subtracter 66 and for the apparatus with negative feedback loop 62<SP>1</SP> a sum output is obtained at addition network 67.

Title: Improvements in or relating to apparatus for the production of combustible gas
Inventor: MILNER GEOFFREY
IPC: C01B3/46
Filed: 1961-09-15
Abstract: <PICT:0936699/III/1> An apparatus for producing combustible gas by the catalytic reforming of fluid hydrocarbons in a cyclic process comprises a vessel 1 containing catalyst 2 between free end spaces 3, 4, and regenerator vessels 7, 11 containing heat storage refractory material 8, 12 between free end spaces 9, 10 and 13, 14 respectively. The apparatus is adapted to carry out the "uniflow" process (i.e. the direction of gas flow is the same in the plant-heating and gas-making periods) and the regenerative process in which the direction of gas flow is opposite in alternate periods.  In the uniform process, fuel and air are delivered to a burner 51, the combustion gases passing right to left through the apparatus to a stack 19 during the heating period, while steam and liquid or gaseous HC fuel are delivered at 62, 53 respectively during the make period.  Air may be delivered at 58 via line 36 during either period, for cooling or for making a nitrogen-containing gas, the gas passing to a washbox 25.  In the regenerative process, different connections are employed.  In the heating period, air enters via line 38, is heated at 12 and burns deposited carbon at 2 to heat the catalyst, fuel and air being burnt, if desired, at 44 and 58.  During the make period, steam enters the vessel 7 at 60, is preheated at 8, mixed with HC oil entering at 48 and the mixture passed through the catalyst 2 to produce combustible gas which heats the material 12 on its way to the washbox 25.  In the regenerative process, air may be introduced through line 65 in either period for cooling or for making a nitrogen-containing gas.  In both processes, purge periods follow each heating and make period.  A substantially similar apparatus is described, see Fig. 2 (not shown) in which two washboxes are employed, one at each end of the apparatus.

Title: Improvements in textile threads and fabrics
IPC: D02G1/02
Filed: 1937-12-04
Abstract: 507,061. Composite yarns; crimping yarns. FINLAYSON, D., and BEZANT; R. Dec. 4, 1937, No. 33620. [Class 120 (iii)] A crimped yarn is produced by doubling together one or more component threads, that have been crimped by setting therein twist imparted by a false twisting device fitted with a yarn trapping device with which the thread makes an angle of contact of more than 90‹, and one or more component threads having a lower or less permanent degree of crimp. The components may be obtained by the methods described in Specifications 424,880, 442,073, and 464,981, the more permanently crimped threads being produced by arranging the angle of contact of the thread leaving the false twisting device with the trapping device to be greater than 90‹, e.g. 180‹ up to 360‹ or more, and the less permanently crimped threads being produced by arranging the angle of contact to be less than 90‹ or when the latter threads are of cellulose acetate and preferably containing filaments of flat cross-section they may be crimped by the action of a hot aqueous medium. The components having the higher or more permanent degree of crimp may be fed, in the doubling operation, at a lower rate than the remaining components and two of the composite crimped yarns may be doubled together. As shown in Fig. 2, the yarn 33 to be given the higher or more permanent degree of crimp, is passed around the trapping hook 32 of the apparatus described in Specification 464,981 so that it is constrained to turn through a substantial angle and make an angle of contact with the hook of more than 90‹ and in Fig. 4, an additional hook 34 is provided on the false twisting device 14 to give the increased angle of contact. Specifications 482,376, 482,426, and 503,923 also are referred to.
Patent GB-336767-A (GB)
Abstract: 336,767. Mathys, A. W., (Monroe Calculating Machine Co.). Sept. 27, 1929. Adding, subtracting, multiplying, and dividing apparatus.-A calculating-machine may be conditioned to operate as a key-set or as a key-responsive machine. As shown applied to the Monroe machine described in Specification 216,174, the pushing-in of a key 210 acting through a cam-- slide 209 raises the frame members 211 carrying the toothed bars 204 so as to bring the teeth 203 within the influence of the value keys 18. When one of these keys is depressed therefore it shifts its toothed bar longitudinally so as through a pin 205 to rock a fork 207 and thereby the shaft 125 to start the machine. The direction of the rocking and therefore whether the operation shall be additive or subtractive is determined by a key 200, operation of which places the teeth 203 behind or in front of the keys 18. To ensure non- repetitive action when the machine is conditioned for key-response, the slide 209 has a cam 212 to rock a lever to depress the non-repeat key. In a modification there is only one bar 204, this being applied to a solitary bank of keys, the machine being key-set so far as the other banks are concerned.

Abstract: 1397591 Diagnostic testing of peripherals INTERNATIONAL BUSINESS MACHINES CORP 20 July 1972 [5 Aug 1971] 33912/72 Heading G4A A data processing system includes one or more central processing units (CPU), a group of peripheral devices arranged such that a subsystem of a selected one or more of the peripherals may be assigned for operation with a selected CPU, and a peripheral control unit arranged in response to CPU instructions to initiate normal and diagnostic operations in a subsystem of peripherals, the control unit including a store for diagnostic flags to inhibit, during diagnostic operations, the transfer of selected status information from the subsystem to the CPU, and means for erasing the flags when diagnostic operations areterminated to allow normal processing operations to be performed by the CPU and its assigned subsystem. Diagnostic tests may be performed in a selected subsystem concurrently with normal processing operations in other parts of the system. Basic system.-Two CPUs 110 and 116 are connected via respective channel processors 114, 118 to a peripheral control unit 11 which is connected via an interface 157 to a group of peripherals, e.g. magnetic tapes. Further control units 158, 159 and CPUs 160 may also be connected to the interface. Control unit 11 includes a switch provided with priority circuits for selectively connecting one of the CPUs 110, 116 to the interface. Control unit 11 also includes two microprogrammed processors, one associated with the CPU channel processors 114, 118 and the other with the I/O devices. The two microprogrammed processors are structurally similar and include a microprogram store (read only or read/write), a normally incremented address register, means to modify the contents of the address register to produce program jumps and branches in response to instructions or external stimuli, an arithmetic and logic unit, a local read/write store, and various control logic. Each processor has its own particular program and the processors are interconnected for synchronization etc. Diagnostic tests.-A CPU issues a " SET DIAGNOSIS " command to initiate diagnosis in an assigned subsystem of peripherals. The subsystem is chained to the command to prevent interruption of the diagnosis. The CPU then sets certain indications in the subsystem and checks for the correct responses. Arrangements are described for selectively lifting the chaining to allow diagnostic and normal operations to be interleaved. Several micro-instruction sequences are described for performing various operations.

Abstract: 920,617. Extruding. L. SCHULER A.G. Oct. 7, 1960 [Oct. 10, 1959], No. 34443/60. Class 83 (4). Blanks 13 are fed to a horizontal cold impact extrusion press by a feed device comprising guides 8, 9 for the blank and a lever 37 for moving the blank positively into a final position in front of the die 2. The blank is moved positively or preferably falls by gravity down guides 64 where it is held initially by a pin 59 and then by a pin 60 on a pivoted arm 58. When the pin 60 is released by engagement of arm 58 with an adjustable stop 63 on a lever 37, the blank falls down guideways 10 in a pair of bell cranks 8, 9 mounted on adjustable pivots 17, 18 and pulled against adjustable stops 29, 30 by springs 27, 28. The blank falls against shouldered portions 12 of the guideways and is subsequently pushed downwardly therefrom and into locating recesses 8<SP>1</SP> 9<SP>1</SP> aligned with the bore 1 by a projection 44 on lever 37 which has been moved clockwise about its pivot 36 by a cam 31. This cam acts on a bell crank 33 engaging an arm 35 pivoted at 36 and adjustably connected to lever 37 by clamp bolt 38 and adjusting screws 40, 41. Lever 37 is loaded by spring 42 and its clockwise movement is limited by adjustable stop 65. Alternatively the spring 42 may be omitted and the lever 37 moved positively in both directions. Projection 44 is spring- loaded and pivoted at 43 to the end of the lever; it co-operates with an adjustable stop 46 and with en electric contact 49, in series with a second contact controlled by cam 52 to stop the press if the projection 44 does not engage behind a blank resting on shoulders 12 and also if the blank 13 is not pushed into its correct bottom position. The blank is extruded rearwardly and its emerging wall engages wedge surfaces on the recesses 8<SP>1</SP>, 9<SP>1</SP> to open them. If the extruded products fails to be ejected it is engaged by an electric contact 48 which stops the press. The feed device is detachably secured to the press by screws 6 and locating pins 7 or it may be hinged thereto. The recesses 8<SP>1</SP>, 9<SP>1</SP> may have straight sides and an abutment is then provided below the die bore 1 to locate the blank.
