Patent GB-2436733-A (GB)
Title: Charge pump with cancellation of current mismatch effects and suppression of clock feed-through
Inventor: LEE CHAO-CHENG
IPC: H03L7/089
Filed: 2007-03-29
Abstract: A charge pump circuit suitable for a phase locked loop comprises a current source enabled by a first logical signal (Up), a current sink enabled by a second logical signal (Dn), an integrating capacitor (Cx) coupled to both the current source and the current sink, a loop filter (242) connected to an output node, and a switching device (S130) coupled between the integrating capacitor and the loop filter and output node. The switch (S130) is controlled by the first and second logical signals (Up and Dn), and by a lock detect (LD) signal of the phase locked loop. The switch couples the integrating capacitor to the loop filter only at a defined time (phase 2, fig.3) in the period of the reference clock (To, fig.3) of the phase locked loop. It is also disclosed that the magnitude of the current source may be about twice as large as that of the current sink. The switch S130 may furthermore be controlled by a modulating signal (MOD, fig.5) which may be a pseudo-random sequence. The effect of this is to 'whiten' any noise that is introduced by switching activities and to reduce a spurious spectral component at the reference frequency.

Title: Improvements in driving mechanism for indicators
Inventor: ADSHEAD CHARLES WILLIAM
IPC: A63B71/06
Filed: 1953-04-13
Abstract: 728,102. Changing signs. SETRIGHT REGISTERS, Ltd. April 13,'1953, No. 10056/53. Class 3 (1). [Also in Groups XIX and XXXVIII] A multi-position indicator comprises a series of slats attached to an endless chain driven step-by-step by a motor whose energizing circuit includes a series of switches of which a selected one is open, the shaft rotating until a driven rotary switch finds the open switch position corresponding to a desired slat being opposite a window, there being a parallel motor-energizing circuit containing a cam-operated switch to ensure that the slat is aligned with the window. As shown, three vertical shafts 4 (Fig. 2) are driven by a motor 28 via gearing 18, 20, the shafts having sprocket wheels 8 driving endless chains to which are attached ten slats 10 by brackets 12. An intermediate gear 50 drives a further shaft 54 carrying an arm 56 moving over ten contacts 62 located in a circle. The motor 28 also drives a star wheel 34 associated with a cam 38 and a plunger 46 operating a micro-switch 48. Each of the contacts 62 is connected to a manually-operated selector switch 66 (Fig. 3) assembled on a spring- loaded bank so that only one switch 66 may be open at any time. Thus, operation of a switch 66 closes the motor energizing circuit, causing the shafts 4, 54 to rotate until arm 56 finds the contact 62 connected to the open switch 66, the motor 28 stopping when the parallel path through micro-switch 48 is also opened, whereby it is assured that the appropriate slats 10 are accurately located relative to a window. A neon lamp 68 indicates when the motor 28 is at rest.

Patent GB-706154-A (GB)
Title: Process of preparing fibres, films, tubes and the like containing polyacrylonitrile
IPC: D01F6/18
Filed: 1952-04-22
Abstract: Artificial filaments, films, tubes, and the like are obtained by extruding a solution of an acrylonitrile polymer into a coagulating liquid in which the solvent for the polymer is soluble at the coagulation temperature, and the solvent is separated from the used coagulating liquid by cooling the mixture.  If desired, a substance having high affinity for the polyacrylonitrile solvent but low affinity for the coagulating liquid may be added to facilitate the separation of the solvent.  The spinning solution may consist of a solution of polyacrylonitrile in dimethyl formamide or dimethyl sulphoxide and the coagulating liquid may be a hydrocarbon such as cymene, xylene, toluene, or benzene, or a kerosene containing a mixture of aliphatic and aromatic or hydroaromatic hydrocarbons, or it may be iso-octane.  Water or methanol may be added to the used coagulating liquid to facilitate separation of the solvent.  When dimethyl formamide is used as the solvent, the coagulating liquid may be an aromatic-free kerosene. The filaments may be subjected to stretching at a temperature above 100 DEG C. e.g. in air or in hot kerosene, and to subsequent heat setting e.g. in steam, while free to relax.  In an example, a solution of polyacrylonitrile in dimethyl formamide is extruded through a spinneret situated at the bottom of a long tube containing kerosene which has a content of 10-15 per cent. of aromatic hydrocarbons.  The filaments pass upwardly through the tube while the kerosene at 135 DEG C. flows downwardly.  After leaving the spinning tube, the kerosene is cooled to 15 DEG C. so as to cause separation of a dimethyl formamide phase and a kerosene phase. The kerosene phase may be re-used directly or may first be washed with water to remove most of the dimethyl formamide.  The dimethyl formamide phase may be fractionally distilled to remove most of the hydrocarbons.  If desired this separation may be improved by adding to the dimethyl formamide phase water which has previously been used to wash the kerosene, and separating further hydrocarbons before carrying out the distillation.  The separated dimethyl formamide may be used directly to prepare fresh spinning solution. In another example, a solution of polyacrylonitrile in dimethyl formamide is extruded into a hot mixture of kerosene and cymene.  The used coagulating liquid is cooled to 25 DEG C. to cause separation of a dimethyl formamide phase.  The separation is substantially improved if about 10 per cent. of water, calculated on the weight of dimethyl formamide, is added.  Specification 686,023 is referred to.
