Title: Improvements in change-speed gears more especially for driving tuning controls of wireless apparatus
IPC: H03J1/14
Filed: 1939-02-08
Abstract: 524,837. Friction gearing. PLESSEY CO., Ltd., and MORRISON, P. H. Feb. 8, 1939, No. 4179. [Class 80 (i)] [Also in Group XXXVI] A change speed drive particularly for the coarse and fine tuning of a wireless receiver comprises an interrupted change speed gear rotated by the driving member and carried on the driven member offset thereto, which gear is engaged with a co-operating member coaxial with the driven member for one part of the rotation of the interrupted gear to give an indirect drive, and is disengaged therefrom for another part of the rotation, due to the interrupted part of the gear, when the driving member is locked with the drive member to give the direct drive. The driving and driven shafts 10, 11 are connected by a slotted arm 19 fixed to a boss 20 rotatable on a pin 21 carried by a bracket 22 fixed to the shaft 11 so that the pin is parallel to but offset from the shaft 11. A disc 16 fixed to the shaft 10 carries a boss 17 which engages in the slot 18 in the arm 19 so that on rotation of the shaft 10 drive is transferred to the arm 19 through the boss 17 which gradually moves down the slot 18 until it reaches the end thereof whereupon a direct drive is obtained. The reduction gearing which operates during the indirect drive comprises a flange 23 via a boss 20 which is frictionally engaged between a flange 24 on a boss 25 on the shaft 11 and a spring pressed disc 26. The perimeter of the flange 23 is interrupted to form two parallel sides 29, 30 so that the remaining flanged operative part 31 is in engagement with the friction gear 24, 26 only during the indirect drive. The drive is transmitted to a driving disc 15 fixed on the condenser rotor shaft through spring pressed friction flanges 12, 13. The change speed gear may be inserted between the sensing contact member and a driving motor for rotating same e.g. of the kind described in Specification 501,273, [Group XXXVI], a reversal of the motor drive thus automatically giving a reduced gear ratio which prevents hunting. Reference has been directed by the Comptroller to Specification. 524,245.

Abstract: 524,879. Drawing curtains and the like. MALLENTJER, V. B. M. Feb. 9, 1939, No. 4318. Convention date, April 12, 1938. Addition to 519,839. [Class 52 (v)] [Also in Group XXX] The apparatus of the parent Specification is modified in that the motor 26 is journalled at 28 in a casing 27 to which it is connected at its lower end by a tensioned spring 29 which presses the friction wheel 30 on the upper end of the motor shaft against a friction disc 31. The curtain or like cord 35 passes round a pulley 34 on the disc spindle 32, the pulley being accommodated in a depression 33 in the casing 27, and the casing thus suspended is guided in vertical grooves. The motor 26 is of the universal type, and reversal of current through the rotor is effected by a switch comprising two push buttons 17, 21, Fig. 2', bearing on the ends of an insulating rocking lever 18 co-operating with contact springs 19-20, 23-24. Pressure on one of the buttons to cause its contact spring to make the corresponding circuit automatically raises the other button to break that circuit. An adjustable spring-pressed brake pad 41 bears on the disc 31.

Abstract: 870,234. Induction machines. SPERRY GYROSCOPE CO. Ltd. Jan. 8, 1960 [Feb. 10, 1959], No. 4697/59. Class 35. In a tachometric signal generator comprising a stator having windings 1, 2 in quadrature and a conductivecylinder rotor 4 which varies, by its speed of rotation, the coupling between the windings, one component of the coupling at zero speed is reduced, ideally to nothing, by inducing in one winding a current of appropriate phase and magnitude. The windings comprise energizing and signal coils respectively, and the correcting current is induced in the latter by a stationary but angularly adjustable cylinder 8 which comprises two short-circuited turns. These may be formed by apertures in an otherwise conducting cylinder, or they may be conducting turns " printed " or otherwise arranged on an insulating one; alternatively the cylinder may be replaced by conducting, discontinuous rings. Preferably the cylinder or rings are carried by a member 6 of magnetic material which has a flat 7 to produce asymmetry of the magnetic field so that, by suitable positioning, the other component of the coupling at zero speed (i.e. that in phase with the energizing winding) is also reduced.

Abstract: 423,215. Flexible shaft couplings ; claw, ratchet, and slipping clutches. DORNIG, M., 30, Via Porpora, Milan, and FAUSER, F., 1, Via Alcarotti, Novara, both in Italy. Feb. 15, 1934, No. 5063. Convention date, Feb. 15, 1933. [Class 80 (ii)] An elastic shaft-coupling or clutch comprises solid rubber or other elastic bodies C, of spheroidal, ovoidal, frusto-conical, or like shape, interposed between axial projections 7, on integral coupling-flanges 4, 5, the projections being of such a shape, viz. provided with concave side-faces 1<a>, 2<a>, that on assembling the flanges together, by relative axial movement, the elastic bodies C are first gradually compressed and rolled between the projections and then allowed to expand. The elastic bodies thus tend to hold the flanges in correct axial engagement. In the form shown in Fig. 5, for use as a claw-clutch, the elastic bodies C are carried on radial pins 9 on a cage 8, controlled by means, not described, which always restores it to a central position between the clutch-halves 4<c>, 5<c>. The Specification as open to inspection under Sect. 91 describes with reference to Fig. 7 (Cancelled) a coupling which transmits drive only in one direction and also allows slip on overload. The elastic balls C are jammed by the torque between cam-recesses 2b, in an inner member 5b, and the cylindrical inner face of the outer member 4b. Under heavy torque, the elastic balls are squeezed sufficiently to ride over the tops of the recesses 2b and thus allow slip. The driving-projections on one of the members 4, 5, Fig. 4, may be flat. This subject-matter does not' appear in the Specification as accepted.

Title: Improvements in or relating to well pump filters
IPC: F04B53/10
Filed: 1951-03-05
Abstract: 689,665. Filters. GREENE, H. M. March 5, 1951, No. 5293/51. Class 46 [Also in Group XXVIII] A well-pump filter comprises a tubular body adapted for connection to a pump and incorporating a chamber which contains a mobile mass of mutually-contacting filter particles, means being provided for directing the well liquid upwardly in the chamber, the particles being at the same time agitated or raised en masse. A filter 10, Fig. 10, is screwed at 12 into the lower end of a pump 13 having a piston 14 and inlet valve 15. An assemblage 17 preferably of glass balls each about “-inch diameter rests on a disc 22 having a series of radial slots 24, Figs. 1 and 5, inclined to the vertical and constituting the inlet to a chamber 23 for well liquid drawn into a sump 35 past check valves 40 when the piston of the pump is raised. Liquid also enters the chamber 23 directly through tangential slots 25, Figs. 1 and 5, the liquid thus moving spirally upward and causing a similar movement of the balls so that they occupy the position shown in Fig 3 at the end of the upstroke. During their upward movement the balls 17 rotate about an outlet tube 26 and in addition spin individually. This motion causes excess sand and other solids and water to be separated and fall through the slots 24 into the sump 35 while gas is separated and forces its way past valves 34, Fig. 3. During the start of the pump downstroke, Fig. 4, that is, before the valve 15 has reached its seating, there is a brief downward surge of well liquid into the chamber 23 which forces out the last of the gas and in addition forces the sand &c. from the sump 35 out past a ball valve 37. As the downstroke continues balls 17 falling upon the disc 22 pound the matter on it through the holes 24 into the sump. The ball 37 preferably has a density slightly less than that of the well liquid so as to be normally in the upper (closed) position, Fig. 1, and thus prevent inflow of well liquid during the pump upstroke. The valves 40, Fig. 1, are located so as to be above any accumulation of sand &c. in the sump 35 and are closed by springs 41, Fig. 1, during the downward surge of liquid, Fig. 4. In the embodiment of Fig. 7, a further sleeve 42 is provided outside 'the filter body 10 and is secured at 43 to its head section 18a. The check valves 40 are omitted from the sump sections 20a which in this case is screwed to the sleeve 42 at 46. Well liquid is constrained to enter the apparatus through openings 44 near the top of the sleeve 42 so that solids and water separate during the downward flow in the annular space 45 and are deposited in the sump 20a. Solids and water which separate in the chamber 23 fall through the slots 24a into the sump as before. In both cases the tapering 27 of the outlet tube 26 lessens resistance to upward movement of the assemblage of balls 17.

Abstract: 833,303. Coin-freed vending apparatus. NATIONAL VENDORS Inc. Feb. 18, 1958 [April 17, 1957], No. 5294/58. Class 27 A manually-operated vending machine of the stacked-article type has a member 33 movable to obtain an article P and, to ensure that this member cannot be operated so rapidly by a purchaser that the coin-freeing mechanism or other part of the machine has not time to operate fully, means is provided for imparting momentum to a movable detent 43 so that, if the member is moved at a speed above a predetermined speed, the detent is moved to a position in which it can engage a stop 61. The detent may be pivoted at 45 on the fixed frame of the machine, as shown, or on a member moving with the movable member. The movable member 33 is one of a number, each under a separate magazine and each having a pull-out knob 31. Each article stack rests on a member 33 until released to a shelf 7 when a knob 31 is pulled out and on return of a knob the lowermost article is pushed off the shelf for delivery. As a knob is pulled out, a draw-bar 13 common to all the magazines is also moved out and it moves a side arm 15 forwards. An operating pin 47 and the stop pin 61 are provided on the arm, the operating pin normally lying below the detent to support it and the stop pin lying above and clear of the detent. If the knob is pushed back relatively slowly, the pin 47 acts gently on the angled nose 55 of the detent to raise it from a slightly dropped position, but if the movement is fast the detent flies up to a position where its nose lies in the path of the pin 61 and prevents return of the side arm 15 and of the knob until the knob is pulled out slightly to release the detent. The detent may alternatively be arranged to act near the end of the forward movement of the knob. A reserve magazine AM for an additional supply of articles as described in Specification 833,104 may be provided.
