Title: Regulating the dispensing of particles
IPC: G03G15/00
Filed: 1974-04-10
Abstract: 1457565 Automatic control of concentration; control of toner concentration XEROX CORP 10 April 1974 [16 April 1973] 15859/74 Headings G2H and G3R Particles (toner in an electro-photographic printing machine) are dispensed from a container into a mix in differing predetermined quantities in response to the number of consecutive electrical signals received from means which cyclically detect whether the concentration of particles in the mix is below a predetermined value. Detection is made once per revolution of a photoconductive drum; on the first three consecutive occasions that the concentration is too low a "half" dose of toner is released; if the concentration remains low a "full" dose is released on the next seven consecutive occasions; if the error persists it is assumed the container needs replenishment and the machine is stopped. In the complete machine, coloured toner and carrier particles are electrostatically deposited from respective developer units 28, 30, 32 on to a photo-conductive drum 10 according to the charge pattern applied by charging device 16 and modified by light reflected from a document 22 through a filter unit 20. The colour images are applied sequentially to an output sheet 50 on a lower drum 52, from whence the sheet passes to a heat fixer. The drum has a transparent element 36 outside the image area and this is in a fibre optics path 38, 40, 44 to a detector 42. The output of this is compared with a reference voltage in a logic unit 60 also Figs. 2-10 (not shown); if the reference voltage is exceeded (too little toner) a signal is produced which is counted to operate a vibrating toner dispenser for a prescribed tonic in accordance with the invention. The counter is reset when the "too little toner" signal disappears, or when the container door is opened.

Title: Jaw clutch meshing device
IPC: F16D41/22
Filed: 1956-05-23
Abstract: 792,590. Ratchet clutches. BENDIX AVIATION CORPORATION. May 23, 1956 [June 28, 1955], No. 16014/56. Class 80 (2). A ratchet clutch for an engine starter mechanism comprises a starter jaw 2 having a ring of radially broad teeth 22 in an end face, an opposed blocking ring 17 having teeth engageable with the inner radial portion of the teeth 22 being anchored to the jaw 2 by a torsion spring 25 which draws the two sets of teeth into engagement when wound in one direction, and moves them out of engagement when wound in the other direction. The spring 25 is a substantially circular flat spring having outwardly extending lugs 26, 27 secured respectively to the jaw 2 and the blocking ring 17, circumferential movement of the ring being limited by a stop 32 on the jaw 2 engaging a slot 33 in the ring. In operation, actuation of a helical drive screw 5 by the starter in known manner, causes the jaw 2 to advance towards an opposed jaw 12 connected to the engine, the end face 23 of the blocking ring enters a recess 24 in the jaw 12 and is rotated by the friction drive thus obtained. This rotation draws the teeth of the ring and the jaw 2 into engagement and causes engagement of the teeth of the two jaws 2 and 12 to start the engine. When the speed of the jaw 12 exceeds that of jaw 2 the teeth are thrust out of engagement and the blocking ring rotates in the opposite direction to cause the teeth on it to ride on to the tops of the teeth 22, thus holding the clutch disengaged and preventing clashing of the teeth.

Patent GB-160559-A (GB)
Abstract: 160,559. Adams, A. J. Dec. 23, 1919. Magnetos, driving. - Relates to trip-mechanism for producing accelerated movements of an ignition magneto when an internal-combustion engine is running slowly and of the kind having driving and driven members connected by one or more springs which are placed under stress by the temporary stoppage of the driven member owing to a pivoted detent d on a stationary part entering one or more notches b in the periphery of the driven member. The invention consists in forming the notch or notches b with the rear or trailing wall in two parts; one part c constitutes the abutment :for the detent, whilst the other part f is bevelled so that when the member a has at- - tained a predetermined speed the detent is unable to drop sufficiently to abut against the part c, but falls on the part f (as indicated in dotted lines) which slides thereunder and consequently the driven member is not arrested.

Class 40 (viii). , [Also in Group XL (c)] Frequency modulation of an oscillator is linearized by coupling it to a transmission line of distributed impedance or wave-guide of a plurality of wavelengths long having near its load end a lumped impedance, e.g. a screw 3 adjustably projecting into the line or guide to produce reflection, and by adjusting the electrical length of the line or guide between the oscillator 1 and lumped impedance 3, as by a thin sheet of dielectric 5 pivoted at one end and projecting adjustably through a longitudinal slot 5a in the line or guide. Alternatively electrical length adjustment may be produced by a further screw 6, Fig. 2 (not shown), between the screw 3 and oscillator. The lumped impedance 3 may alternatively be a slot in the wave-guide. The line or guide may be fed from a reflex klystron, or continuous wave magnetron or from an oscillator with reactance valve modulator. The distance 1-3 between oscillator 1 and impedance 3 should be where # 9  is the guide wavelength, n is an ... integer which should be small for linearizing large frequency deviations but large enough to prevent excessive output power variation during correction, and # is a critical fraction. The screws 6, 3 may be mounted on a plate and jointly movable along a slot on top of the guide wall. The line or guide may be in series with the oscillator output or in parallel with it, Fig. 6 (not shown), in the latter case terminating in a dummy load. This assembly may be built into an oscillator. A plurality of correcting lines or guides may be used.

Class 38 (v) In a thermostatic switch having screw adjustment for setting the operating temperature of the switch, fine adjustment is provided by an auxiliary screw mounted in the main adjusting screw. In Figs. 1 and 2, contact carrying spring blades 17, 18 and a bimetallic strip 27 are mounted in a housing 11, which is substantially of channel section and adapted to be secured by a single screw 41 to the sole plate 14 of an electric iron or to the body of another appliance, rotation of the housing about the axis of the screw being prevented by a portion 12 of the housing engaging in a recess in the sole plate or body. The strip 27 actuates the contacts through the medium of a stirrup 26 secured to the underside of the blade 18 and the operating temperature is set by the adjustment of the contacts relative to the strip 27 by a main adjusting screw 30 threaded into a nut 31 secured to the housing 11, the initial fine or factory adjustment being effected by the adjustment of the auxiliary screw 37, within and relatively to the main screw 30. After adjustment, the auxiliary screw is frictionally held within the main screw by means of its eccentric head 38 bearing on the wall of the hole 39 in the main screw. Alternatively, the head and shank of the auxiliary screw may be bifurcated, the bifurcations engaging the inner wall of the main screw to provide the required frictional resistance, Fig. 4 (not shown).

Title: Improvements in the purification of anhydrous aluminium chloride containing iron
IPC: C01F7/62
Filed: 1930-05-26
Abstract: In the purification of anhydrous aluminium chloride containing iron compounds by converting the aluminium chloride into a liquid aluminium chloride-phosgene compound, separating the latter from undissolved ferric chloride and recovering aluminium chloride by evaporating the phosgene, the material is treated with an oxidizing agent, preferably chlorine, during or after the phosgene treatment. The ferric chloride present is preferably reduced to ferrous chloride, as by means of iron or aluminium, prior to or during the treatment with phosgene, and ferric chloride then reformed and precipitated by chlorine, whereby the recovery of aluminium chloride is rendered more complete.  The phosgene may be employed in the liquid state under pressure, or gaseous phosgene be used.
