[Class 27] Articles stored in compartments of rotary drums.-Articles to be vended are stored in fixed superposed annular containers 8, 9 divided into compartments by movable partitions 7, 10 secured to spiders 6, 11 freely mounted on a shaft 3, and separately movable step-by-step to effect delivery through an opening 30, for successive prepayments, under the action of springs 22 which are wound up when the compartments are reversely rotated for filling. Coin-action, mechanical-connection.-In the construction shown in Figs. 1, 2 and 3, the spiders 6, 11 are each locked by a pivoted detent 24. Separate insertion slots are provided for each spider leading to respective slotted coinreceiving arms 14, 15. Upon rotation of the shaft 3 by an actuating knob 13, one of the detents 24, according to the slot used, is engaged and tripped by the coin, permitting rotation of the corresponding spider through one step so that an article is brought before the delivering opening. In the modified construction of Fig. 5, the locking detents comprise levers 38 pivoted at 37 having notched parts 41 extending through an inner wall of the compartments so as to engage the partitions 7. The arms 38 of the levers, are provided with full stroke rack teeth, which are engaged by the inserted coin upon rotation of the actuating knob so as to tilt the lever, and permit rotation of the spider through one step. Coin discharging-mechanism.-In Figs. 1, 2 and 3 the slotted arms 14, 15 are provided with spring-actuated pivoted levers 19, having inturned ends for supporting an inserted coin, and which engage resilient abutments 21 during the return movement of the arms to release the coin. In Fig. 5, the levers 19 engage fixed stops 45 to release the coin at the end of the forward movement of the arm.

Abstract: 1,194,980. Preparation of electroless deposition bath. INTERNATIONAL BUSINESS MACHINES CORP. June 20, 1968 [Oct. 30, 1967], No. 29426/68. Heading C7F. An electroless plating bath is prepared by the steps of (1) providing a first solution containing Ni<SP>++</SP> ions and NH 4 OH dissolved in water in which the molar ratio of Ni<SP>++</SP>   to NH 4 OH is in the range 0À055 to 0À16 (2) providing a second solution containing iron ions of which at least 90% are Fe<SP>+++</SP>, and the remainder Fe<SP>++</SP> and tartrate ions dissolved in water, said Fe<SP>+++</SP> to tartrate ion ratio being maintained in the range 0À02 to 0À3, and said solution being adjusted to a pH of about 10, (3) adding said second solution to said first solution, and thereafter optionally adding water to form a combined solution, (4) providing a third solution containing a reducing agent in amounts sufficient to reduce said Ni and Fe ions to their metallic state during a plating operation and adding said third solution to the combined first and second solutions. The first solution may have 0À02 to 0À4 moles Ni<SP>++</SP> per litre, and NH 4  Cl may be added to the solution to give an NH 4 <SP>+</SP>:NH 4 OH ratio of 1À0 to 1À3:1. The iron ions in the second solution may be present in an amount of from 0À003 to 0À04 moles/litre, and tartrate ions in an amount of 0À06 to 0À5 moles / litre, whilst the third solution may contain 0À024 to 0À25 moles H 2 PO 2 <SP>-</SP> per litre. The bath is used to deposit uniaxial magnetic films of Ni/Fe on substrates such as Cu, or films of Ni/Fe/Co, in which case a fourth solution containing a cobalttartrate complex is added to the bath described above, the plating process in each case being performed at 15-45‹ C. Non-conductive substrates may be sensitized by standard techniques. For optimum magnetic properties, the relative amounts of bath constituents are critical, and graphs are provided from which these amounts may be determined.

Title: Improvements in arrangements for supplying electric current to optical sound recording or reproducing systems

Abstract: 409,012. Electric incandescent lamp . filaments. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Dawson, W. L. ; 233, West 21st Street, New York, U.S.A.) Oct. 22, 1932, No. 29543. Convention date, Jan. 9. [Class 39 (ii).] In a system for supplying electrical energy to optical sound-recording or reproducing- systems which include an electric incandescent lamp required to give a very steady light emission, alternating current rectified by a rectifier 27 is delivered through a filter circuit, consisting of inductances 28, 29 and condensers 34,35, to shunt-connected circuits comprising the lamp 12 and a load which may consist of the filaments of a thermionic amplifier 30, the ripple component of the current through the lamp filament 15 being substantially reduced by a series resonant circuit consisting of an inductance 32 and condenser 33 connected in series and shunted across the supply lines, with their common point connected by a conductor 16 to the mid-point of the filament. The currents flowing in the two halves of the filament thus differ in phase by 90‹ so that the total light emitted by the lamp at any instant remains substantially constant. To avoid a dark spot at the centre tapping of the filament the lamp is preferably of the form shown in Fig. 2, with resilient leading-in wires 13, 14 across which the flat vertical filament 15 is stretched. A leading-in wire 16 sealed in the foot-tube 11 is bent horizontally to form a centre support for the filament, and is bent at right-angles and flattened at 17, Fig. 3, to provide a portion at right-angles to the longitudinal axis of the filament. The filament is wrapped around the flattened portion 17 of the wire 16, and retained in position thereon by a resilient clamp 19 of material such as molybdenum. The edge 18 of the portion 17 may be tapered, and the edges of clamp 19 may also be tapered to a thin edge.

Abstract: 656,217. Aircraft controls. AERO DESIGNS, Ltd., and SUPPANCIC, G. O. Nov. 15, 1948, No. 29601. [Class 4] Apparatus for simulating feel in poweroperated aircraft controls comprises a strut supported at one end on a rotatable support for free and elastically restrained movements respectively about perpendicular axes disposed at right-angles to the longitudinal axis of the strut, the support being rotatable for altering the position of the axes in relation to the plane of movement of the control member, and linkage connecting the other end of the strut to a control operating member so that movement of the latter is communicated to the strut, movement of this end of the strut being confined to one plane. As shown in Fig. 1, the strut 13 is in the form of a leaf-spring whose upper end is connected by a ball-joint 14 and a member 12 to the upper end of a pivotal lever 10 operated by the control column, its lower end being provided with pins 16 mounted in bearings in a rotary member 19 connected by an arm 23 to an airspeed indicator, Mach meter, or other device responsive to airspeed or dynamic head. At low speeds the pins 16 are nearly parallel to the pin 11 at the lower end of the member 10, so that movement of the control column causes pivotal movement of the strut 13 about the pins 16, with little or no flexure of the strut. With increase of speed the support 19 and strut are rotated about the latter's longitudinal axis, so that an increased force must be applied to the control column to effect flexure of the strut. In a modification, Fig. 2 (not shown), the strut consists of two parallel metal strips connected by rubber blocks operating in shear, while in a further embodiment, Fig. 3 (not shown), the strut is connected to a member carrying the pins 16 by an annular rubber bush or by a simple or compound torsion bar. Specification 614,102 is referred to.
