Title: Control of a high speed brushless motor
Inventor: CELIK TUNCAY
IPC: H02K21/12
Filed: 2009-07-17
Abstract: A motor system (5, fig.2) is disclosed, suitable for operation at high speed, e.g. above 60,000 rpm, in a vacuum cleaner. The motor includes a Hall position sensor and a single winding (19, fig.3) arranged on a C-shaped core (8, fig.3). The winding is excited in advance of zero-crossings of the back-emf in the winding by an advance angle, and is freewheeled over a freewheel angle. Both angles may be varied in response to changes in the speed of the motor and the excitation voltage. The variation of the advance angle and freewheel angle is stored in the drive controller (16, fig.2) as a power map. Each map comprises a lookup table storing an advance time and a freewheel time for each of a plurality of voltage levels. Consequently, constant output power is achieved over an operating speed range spanning at least 10,000 rpm, irrespective of changes in excitation voltage, which may come from a battery. The control system includes an ADC 32 which converts a system voltage to a value that is used to address a look-up table, from which is read data used to trim the control system.

Title: Improvements in automatic record-disc changing gramophones
IPC: G11B17/16
Filed: 1947-04-17
Abstract: 645,836. Magazine gramophones. STAUBO, S. April 17, 1947, No. 10286. Convention date, Dec. 17, 1942. [Class 40 (ii)] In a magazine gramophone for playing both sides of records of mixed diameters, the record release mechanism and pick-up arm movements are controlled by a .cycling cam-member 15, which performs a half-revolution when brought into engagement with a continuously rotating shaft 11, the pick-up arm 29 being moved to play the underside of a record during one half-revolution, and the said record being released from the stack 6 and the pick-up arm 29 moved to play the upper side of the same record during the other half-revolution. The shaft 11 is carried by a frame 12 which is movable about the shaft 2 and is held by a spring-loaded arm 40 while a record is being played so that the driving wheel 13 is out of engagement with the cam-member 15. When the pick-up arm 29 reaches a certain point in its traverse, an arm 48 fixed to the pick-up arm spindle 28 pushes a spring-loaded retaining member 45 out of engagement with one of the stops 47 on a bar 41 pivotally mounted at the centre 16 of the cam-member 15. Under the influence of a spring 44, the bar 41 is thereby urged clockwise and the end 49 or 50 of the said bar 41 engages the wheel 13 and rotation of the cam-member 15 is initiated. Almost immediately one of the pins 21 on the bar 41 engages the spring-loaded arm 40 and releases the frame 12 so that the wheel 13 engages the periphery of the cam-member 15. At the conclusion of the cycle the wheel 13 rides up one of the inclines 51, 52 and the arm 40 re-engages the end 39 of the frame 12 so that drive between the wheel 13 and the cam-member 15 is interrupted until a further cycle is initiated. Control of the vertical movements of the pick-up arm 29 is effected by a cam 22 on the underside of the cam-member 15, said cam 22 acting through a lever 23, spring 26, arm 24 and rod 27. On the underside of cam-member 15 there is also a cam 17 which co-operates with a lever 18 which serves to release a record, by known means, on to the turn-table 3 at every other half-revolution of the cam-member 15. At the end of the playing of a record the pick-up arm is swung out beyond the edge of the records by means of one or other of the pins 37 which comes into contact with arm 48 fixed to the pick-up arm spindle 28. The same pin 37 later comes into contact with the arm 54, Fig. 4, of the lever 54-53 mounted beneath the motor board and leads the pick-up arm to a position over the plain part at the edge of the record, and is fed, after being lowered on to the record, into the start of the groove by a spring-loaded lever 55 at the end of the arm 54.

Patent GB-579330-A (GB)
Title: Process for crystallizing salts
IPC: B01D9/00
Filed: 1943-06-28
Abstract: 579,330. Crystallizing salts. DEHN, F. B. (Potash Co. of America.). June 28, 1943, No. 10434. [Class 32] A salt is crystallized from a saturated solution of that salt, the solubility of which in the solution increases with rise of temperature for temperatures greater than the normal boiling point of the saturated solution, by heating a mixture of the salt and a solution of the salt which is saturated under normal pressure conditions, under a pressure greater than atmospheric pressure and to a temperature above the normal boiling point of the saturated solution so that part of the salt dissolves, while some remains in the solid state to afford nuclei for subsequent crystallization, and then cooling the solution to effect crystallization on the nuclei. The process is employed in making uniform crystals from extremely fine salt particles of varying sizes, and also in the production of very large crystals. Preferably the mixture should be agitated during the heating and the cooling stages; and rapid cooling, with simultaneous release of the pressure on the mixture, should be employed. Good results are obtained when the mixture is heated to between 300‹ and 400‹F. for three to four hours. Potassium chloride, of which more than 50 per cent. passed a 100-mesh screen, was crystallized in five batches using 10.5, 7, 6, 5, 4 lbs. of salt per gallon of brine. In each case the product consisted principally of particles of uniform size of which more than 95 per cent. were retained by a 100-mesh screen, and the impurities were reduced from 3 to 1 per cent. Potassium chlorate and sodium nitrate are also particularly amenable to treatment. An autoclave mounted for rotation and exteriorly heated may be used and cooling may be accelerated by release of the accummulated pressure, followed by spraying the exterior of the autoclave with water. Lifter blades or projecting fins may be used to agitate the charge.

Abstract: 829,585. Uptwisting filament yarns. BRITISH NYLON SPINNERS Ltd. March 20, 1958 [March 30, 1957], No. 10460/57. Class 120(2) In uptwisting low-twist multi-filament yarns, e.g. of synthetic linear polyamide to a low degree of twist in which mechanism is provided for drawing yarn from an upstanding high-speed spindle over a guide above the spindle to a take-up package, a false twist is imparted to those succeeding lengths of yarn in the balloon-phase between the supply package and the yarn guide. In Fig. 1, the false twist is imparted by a friction ring 11 of synthetic or natural rubber with a radiused lip in a holder 9 of thick wire integral with the guide. The ring may be rotated in a direction the same as or opposite to that of the filament, and be replaced by a conventional falsetwist tube, by a grommet in the guide itself, or by a rotating rubber bush close above or below the guide. The yarn may contact the ring only at intervals, a movable second ring of metal being provided below the ring.
Patent GB-105478-A (GB)
IPC: A01N59/22
Abstract: 105,478. Lemmens, G. J., and Fryer, P. J. July 13, 1916. Insecticides.-Concentrated preparations, to be used after dilution with water and containing insoluble arsenical compounds as the active principle, are made into a composition of the consistency of cream by the addition of colloids such as glue, potato or other starch, gluten, alkali soaps, compounds of resin with alkalis, gum arabic, gelatine, and albuminous materials. The colloid has a quasi-mechanical action tending to hold the arsenical compound evenly in suspension when the dilution takes place, and to prevent rapid settling and agglomeration, whereby the strength varies rapidly. The state of the art with regard to mixtures of arsenical compounds with insoluble metallic soaps, to colloidal solutions of metals, and to the use of glue and gelatine as binding-agents in the formation of insecticidal pastilles containing arsenic salts, is set forth, and Specifications 13504/11, 21521/11, and 100,302 are referred to.
