Title: Improved drive for machines for spinning artificial silk
IPC: B65H54/74
Filed: 1925-10-03
Abstract: 241,190. Kohorn & Co., O., and Lehner, A. Oct. 9, 1924, [Convention date]. Apparatus for making filaments.-In machines, for spinning artificial silk the gears for driving the bobbins on which the material is wound, the traverse mechanism, the pumps, and the mechanism for the usual belt drive for adjusting the transmission of the motion to the bobbin in accordance with the diameter being wound, are so arranged that the desired adjustments may be made without the necessity of changing wheels and so that the adjustments made are indicated and are readily observable on graduated scales. A shaft 2, Fig. 2, driven through gears 41, 42 from the driving-shaft 1, is provided with a slidable wheel 3 which is moved bv means of a handle 4, Fig. 1, so that an intermediate wheel 6 engages a gear 7 on a shaft 8 connected to shafts 11, 48, which carry the lower cones of the belt gearing 13, 49 that drive the bobbin-driving shafts 14, 16. Similar change-gearing 21, operated by a. handle 19, affords a coarse adjustment of speed to a shaft 20 which is connected by change-gearing 22, affording a fine adjustment, to the shaft 24 that drives the pump shafts 26, 26'. The heart-cams for imparting the traverse to the guides are operated through change-gearing 27 controlled by a handle 64. The ratchet mechanism 61, Fig. 4, for operating the belt-shifting and tensioning lever 31 is driven through changegearing controlled by a handle 69. All the change-gearing is mounted in a casing and graduated scales are marked on the outside so that the denier, withdrawing speed &c., corresponding to the adjustment of the handles, may be read off. The change-gearing for the pumps, instead of being driven directly from the shaft 2 by wheels 53, 54, as shown in Fig. 2, may be driven from a wheel beyond the bobbin changegearing, so that the speed of the pumps depends. upon the withdrawal speed. The arrangement of the change-gearing as shown permits of automatic lubrication of all the wheels and bearings,. as by bucket-mechanism which delivers the lubricant to the upper parts from which it is distributed by pipes. The casing also serves as a protection to the gearing from acid and gases.

Abstract: 245,852. Klugh, H. Oct. 17, 1924. Reproducing - mechanism. - A machine for tracing curves, such as ellipses, comprises a base member 10 carrying two parallel spindles 12, 13 having cranks 16, 17 adapted to be rotated in opposite directions from a, driving spindle 38 by gearing 18, 19, 41, 42. Slidable members 20, 21 fixed in adjusted position on the crank arms 16, 17, which may be graduated are each connected to one pivot of a six-bar lazy-tongs device 24 - - 29. A third pivot 32 of the lazytongs is hollow, and as shown holds a pencil lead pressed by a spring 35 against a sheet of paper under the instrument, but may hold a cutter such as used for milling or engraving. Rotation of the cranks by turning the handle 43 causes the pivot to generate an ellipse or a straight line according as the crank arms 16, 17 are of different or equal lengths respectively. By varying the angular velocity of the cranks a variety of ornamental designs may be produced. The pivot 32 may also execute harmonic motion. In this case if the instrument is given translational movement the pivot 32 may trace out sine curves. For this purpose the instrument may be carried by a framework 50 supported by rollers 53 on the ends of spindles 51, 52, motion of the rollers 53 being communicated to the shaft 38 by bevel, chain, or belt gearing 55 and an infinitely variable gear 57. The rollers 53 may be mounted directly on the pedestals 11 of the base 10.

Abstract: 733,562. Photo-electric particle counter. CINEMA-TELEVISION, Ltd. Oct. 2, 1953 [Oct. 2, 1952], No. 24691/52. Class 40 (3). In particle counting apparatus of the type in which an area is scanned in contiguous lines by a radiation beam the beam is produced by two effectively alternately operative sources, means responsive to detection of a particle by the beam-directing signals alternately in synchronism with the sources to different input terminals of an anti-coincidence device to provide an output signal when an input signal is effective at one of the input terminals only. As described the two sources may consist of alternately energized gas discharge tubes or of two sources, alternately obturated by a shutter and arranged to scan the surface by means of a scanning disc or, as shown in the drawing, by a cathode ray tube. In this embodiment a single light spot is arranged to oscillate rapidly between the two scanning lines. As shown, light from a normal television raster produced by deflection coils 5 of a cathode ray tube 1 supplied by time-base circuits 6; 7 passes through sample 12 to photocell 14. In addition square pulses supplied by a circuit 9 are applied to coils 8, 8<SP>1</SP> thereby causing the spot to deflect between the two contiguous scanning lines during its progress along a line. Simultaneously, circuit 9 feeds its output to a switching circuit 15 which arranges that the outputs from the photo-cell corresponding to the detection of particles in the two scanning paths of the beam are fed alternately to the two inputs of a coincidence circuit 16. The arrangement is such that a counter 17 is operated only provided that a pulse produced in one beam is not followed by one produced by the other thus indicating that a particle overlaps the scanning beams. Alternatively the last pulse may be counted or both the first and last when the total count must be divided by two.

Title: Improvements in and relating to the treatment of oxide coated aluminium and aluminium alloy surfaces
IPC: C25D11/24
Filed: 1931-09-03
Abstract: Aluminium or aluminium alloy articles having a surface oxide layer produced electrolytically are treated with a solution, preferably hot, of a substance or substances adapted to soften and loosen the oxide layer and make it flexible, the oxide layer being then impregnated with filling, binding, or insulating substances such as paraffins, oils, waxes, lacquers, or resins.  The softening and loosening substance may be a hydrate or carbonate of an alkaline-earth metal or an alkali metal, or inorganic acid, a salt of an alkali metal, e.g. potash alum, or an aluminium or chromium compound such as an aluminium or chromium soap.  Examples are given of an aluminium wire electrolytically oxidized in a mixture of oxalic and chromic acids and then treated in a caustic soda solution at 30 DEG  C., washed with cold water, treated with nitric acid to neutralize the caustic soda, and impregnated by dipping in molten paraffin; and of an aluminium wire electrolytically oxidized in sulphuric acid and then treated in a solution of potassium chlorate at 30 DEG  C. and impregnated by coating with varnish or lacquer. The loosening and the impregnating may be carried out under pressures other than atmospheric and the loosening may be combined with a mechanical treatment, e.g. pressing or bending.  A succession of loosening baths may be employed, the article being dried by heat between successive treatments.  The Specification as open to inspection under Sect. 91 is not limited to the treatment of oxide layers produced electrolytically and also describes the following methods of loosening the oxide coating: (1) treatment with purely organic materials, for example such as are understood by the term "Quellstoffe"; (2) treatment with gases; (3) heating in a vacuum; (4) the reversion of the current in the case of an anodically produced oxide layer so that the aluminium article becomes the cathode.  The use of dyestuffs as impregnating material is also referred to.  This subject-matter does not appear in the Specification as accepted.

Filed: 1959-07-18
Abstract: 971,147. Automatic position synchronizing control. J. C. JOHNSON, and K. JOHNSON, [trading as MEREDITH ENGINEERING CO. ], and L. A. FORRESTER. Oct. 13, 1960 [July 18, 1959], No. 24771/59. Heading G3R. In a system for synchronizing two powerdriven members, rotary signal generators driven by each produce gapped sawtooth voltages any predetermined difference between which is effective to slow down or stop the leading member until synchronism is restored. In a system in which two conveyers are to be synchronized to facilitate interaction between articles they carry, three-phase motors driving them are connected to terminals 10 and 11 respectively. One motor also drives a potentiometer 16 and the other motor a potentiometer 17 so that if they get out of step by more than a predetermined amount a polarised relay 15 operates to stop the appropriate motor by de-energizing a relay 13 or 14 until synchronism is restored. The potentiometers are preferably of the wound-rotor type and constructed so that relay 15 is de-energized during half their revolution to reduce the risk of them becoming a whole revolution out of step. Sensitivity of control is adjustable by a potentiometer 18 controlling the supply to potentiometers 16 and 17. Starting and stopping is effected manually by push buttons 25, 26 associated with a self-holding relay 23. Contacts 27, 28 provide motor overload protection. Synchronizing more than two conveyers and slowing the leading motor instead of stopping it are referred to.

Title: Data processing system

Filed: 1971-04-19
Abstract: 1353925 Digital computers; addressing DIGITAL EQUIPMENT CORP 19 April 1971 [23 March 1970] 25073/71 Heading G4A A digital computer system including a processor unit, peripheral units and a memory unit as described in Specifications 1,353,951, 1,353,995, 1,354,089, 1,354,090, includes a memory addressing system. An instruction includes an operation code defining an operation to be performed and an operand address identifying the memory location of the data. The operand address of the instruction comprises an operand address mode portion and a register selection code. The register selection code portion is decoded and the corresponding signals select one of several registers in the processor unit (Fig. 2, not shown), one of which registers is a programme counter for transferring stored instructions in sequence to the processor unit for execution. The address mode portion indicates whether the selected register contains data, a data address or an address for an intermediate location storing a data address and when the processor has decoded the operand address, it obtains the designated data or data addresses to provide direct, indirect or double deferred addressing. Data, or addresses interleaved with, or obtained from information interleaved with instructions, are obtained by selecting the programme counter. This provides absolute, relative and deferred addressing. The selected register contents are modified if certain address modes are used. A given operation code can be combined with one or two operand addresses or order that each instruction can obtain data from locations in the most efficient manner. The address modes are shown on Fig. 4. For example, (a) Direct addressing.-A mode-# operand address causes selection of the R1 register (Fig. 2, not shown) and the contents thereof are moved to an arithmetic unit as data. (b) Deferred relative addressing.-A mode-7 operand address selects the R7 (the programme counter) register. The programme counter contents are used to obtain an index value from the next programme location. The index value is added to the incremented programme count and the sum is an intermediate memory address from which the data is obtained. Thus the number of memory locations which can be addressed is not directly related to the size of the operand address, i.e. a 6-bit operand address as shown in Fig. 4, can address 32K locations. The instructions may be two operand addresses, and control instructions are also mentioned.
