Title: A method of carrying out x-ray spectrometric analyses of liquids
IPC: G01N23/22
Filed: 1965-06-15
Abstract: 1,088,602. Sample holder. VERENIGDE KUNSTMESTFABRIEKEN MEKOG-ALBATROS N.V. June 15, 1965 [June 17, 1964], No. 25266/65. Heading H5R. A cooled sample holder, for use in the X-ray spectrometric analysis of a substance which is liquid at normal temperature and pressure, ensures that during the analysis, the substance is in a cooled, stiffened state having the same homogenous composition as in its liquid state. The liquid is carried by being soaked up in a mass of absorbent ash-free filter cardboard resting on the cooling element 7 of the holder. The element 7 comprises an array of thermoelements operating by the Peltier effect, connected to terminals 14. Channels (3, Fig. 2, not shown) are provided to allow the passage of cooling water, adjacent the hot junctions within the holder. This cooling is carried out rapidly so that no separating out of solid particles e.g. by crystallization occurs. The free surface of the soaked cardboard is covered by a heat insulating layer e.g. the air layer in a closed glass or plastic container, to prevent condensation of water vapour on the cooled sample surface. The holder may be evacuated so as not to carry air with it when introduced into an evacuated analysis chamber.

Title: Control device for electric motors
IPC: F16K31/00
Filed: 1958-08-08
Abstract: 859,115. Control of motors; controllers. LEFFLER, A., [trading as INSTALLATIONSFIRMA A. LEFFLER]. Aug. 8, 1958 [Aug. 9, 1957], No. 25459/58. Class 38 (3). An electric motor SM drives a shaft coupled to a damper VO and the same shaft carries cams ST2, ST3, for controlling the motor whilst a further cam ST1 is coupled to the shaft through a releasable coupling A. When a change-over switch T engages contact K, the motor starts and turns the cams through half a revolution whereupon contact F2 opens to stop the motor. The shaft is returned to its original position by engaging the switch T with contact V so that the motor operates until contact F3 opens. The shaft is stopped in an intermediate position by placing change-over switch O in the position 1 whereby contact F1 will determine one stopping position of the shaft. The desired angular position of the cam ST1 with relation to the other cams is obtained by releasing the coupling A and closing switch F4, until the shaft reaches a corresponding position. The switch F4 is then opened and the coupling is re-engaged. The switch O may be replaced by an electromagnetic relay, Fig. 2 (not shown). In another arrangement the motor SM drives a damper SP forming part of an oil-heating plant, the cam ST3 being fixedly combined with the shaft of the damper while the group ST1, ST2 operates through the coupling A. The motor starts to open the damper when contacts K, F2 are closed, the contacts F2 opening when the damper is fully opened, whereupon contact F1 closes to ignite burner B. A rise of temperature causes thermostat T to close contact V, whereby the damper is closed and the burner extinguished. If it is not required to open the damper fully when the burner is to ignite, the cams ST1, ST2 are displaced relatively to the cam ST3. The cams may be in the form of two cylinders with a frictional coupling therebetween. A push-button operates through a lever to release the coupling against the force of a spring, Figs. 4-6 (not shown).

Filed: 1934-09-06
Abstract: 443,735. Variable-speed gearing. LOVE, P. P., Redholme, Lochwinnoch, Renfrewshire. Sept. 6, 1934, No. 25648. [Class 80 (ii)] Epicyclic gearing comprises the combination of a main epicyclic gear having an externally toothed sun and an internally toothed coaxial ring wheel constituting driving elements and a planet carrier constituting the driven element, with a controlling epicyclic gear comprising coaxial sun and ring wheels and planet wheels, wherein either or both of the main-gear coaxial wheels can be selectively coupled to a power-driven part and wherein the planet wheels of the two gears are interconnected and carried by the same carrier, means being provided for holding one of the main gear coaxial wheels while the other of these wheels constitutes the driving element, and for selectively holding either of the controlling gear coaxial wheels. A driving shaft 1 with flange 4, and a coaxial driving shaft 2 with flange 5 are adapted to be coupled alternatively or together to the engine, and a flange 6 is provided on the driven shaft 3. The flange 5, which is rigidly connected at 5b to a part 5<a>, is secured to its shaft 2 by screwing up a nut 7b threaded on a sleeve 7 having tapered tongues 7a wedged between the part 5a and the shaft 2. The main epicyclic gear comprises a sun-wheel 8 on shaft 2, an annular wheel 9 on shaft 1, and planet pinions 10 splined to shafts 15 in carrier rings 16, 17. The controlling epicyclic gear, comprises a sun-wheel 18 on a sleeve 22 surrounding shaft 2 ; an annular wheel 19 secured to a drum 24 integral with a part 27 ; and planet wheels 20 each of which forms an integral part of the shafts 15 carrying the pinions 10. Three brake drums 25, 26, 27 are provided for changing speed, these drums having band brakes 28, 29, 30 and 31 respectively, of which one of the last two may be dispensed with. Drum 25 is integral with the part 5a, drum 26 is splined to sleeve 22 and drum 27 is integral with drum 24. A dog-clutch 33 on a sleeve 34 splined to driven shaft 3 may occupy the neutral position shown, engage teeth 35 on a drum 36 secured to planet carrier ring 16 for all forward drives, or engage teeth 37 on a ring 38 bolted to annular wheel 9 for reverse drive. The gearing is housed in a case comprising front and end portions 39, 41 and an intermediate portion 40. The ring 17 acts merely as a supporting ring. The pitch of the teeth in the controlling gear differs from that in the main gear. An example of the numbers of teeth in the wheels and the gear ratios obtained, is given in the Specification. In the case of heavy vehicles requiring a large range of speeds for forward and reverse, a changespeed gear of the well known " clash " type may be interposed between the shaft 3 and the finally driven shaft. Further, where no teeth such as 33 are provided for reversing, another set of epicyclic gear parts may be connected in which the " planet " wheels would have stationary axes and the sun gear would be driven by the shaft 3, the ring wheel being journalled on the finally driven shaft.

Abstract: 456,998. Optical sound - recording apparatus. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Sept. 16, 1935, No. 25694. Convention date, Sept. 27, 1934. [Class 40 (ii)] Relates to optical sound-recording apparatus by means of which either a variable-width or a variable-density record may be produced as desired. According to the invention, the apparatus comprises a light source 10, an aperture 12<1> arranged to be imaged upon a slit 17<1>, and a galvanometer mirror 13 for shifting the image transversely of the slit, the aperture 12<1> comprising a portion of uniform width and varying illumination (the rectangular portion shown in Fig. 3), and a contiguous portion of varying width and uniform illumination (the triangular portion, Fig. 3). For variable width recording, the mirror 13, which vibrates about an axis in the plane of the paper, Fig. 1, is so adjusted that the triangular part of the aperture 12<1> is imaged upon the slit 171, as at A, Fig. 3. The modulated light passing through the slit is focused by a lens 16 upon the film 18, thus producing a variable width track. When a variable-density record is required, the adjustment of the mirror 13 is changed so that the aperture 12<1> is imaged upon the slit 17<1> at the position indicated at B, Fig. 3. A stop 19, inserted in the position shown in Fig. 1, produces a uniform gradation of intensity of light illuminating the rectangular portion of the aperture, this portion being operative when the adjustment for variable-density recording has been made. Visual means for monitoring during recording may be provided as described in Specification 301,391, [Class 40 (ii)], and may be used for monitoring both kinds of recording.

An electrical terminal board (Fig. 8, not shown) is made in a machine having means for injecting electrically conductive and non- conductive material and comprising a stationary platen 16 and a movable platen 11. As shown, a fixed die block 27 is provided with cavities 28, 30 which can be filled with molten metal from an injection system through an inlet 29, and also with an inlet 32 for injecting insulation material. A rotatable die block 20 is provided with two sets of runners 22, 23. The platens 11, 16 are brought together along tie bars 12 so that runners 22 are directly opposite the mould cavities 28, 30, molten metal is injected and flows through runners 22 to fill the cavity 28. The platens are then separated and the moulded frame adheres to the runners of the platen 16 which is then rotated on a spindle 21 through 180 degrees, bringing the framework moulded in cavity 28 directly in front of the inlet 32. The platens are again brought together and insulation material is injected into the cavity formed by the framework. The platens are then separated and the composite article removed by ejection pins 24. The metal runners and excess insulation material are then removed e.g. by grinding. After the first metal framework has been die cast and the die 20 rotated both injection systems can work simultaneously. Figs. 9, 10, 11 (not shown) give modified forms of the runners.

Title: Improvements in and relating to apparatus for producing bores of uniform polygonal cross section
IPC: B23Q27/00
Filed: 1938-09-06
Abstract: 508,443. Boring non - circular holes. JUNKERS FLUGZEUG - UND - MOTOREN - WERKE AKT.-GES. Sept. 6, 1938, No. 26048. Convention date, Sept. 6,1937. [Class 83 (iii)] In a device for boring holes of regular polygonal section the cutter spindle is rotated about its own axis and is also given a planetary rolling motion, the cutting point of the cutter being arranged externally to the rolling circle. The cutter 7 is secured to a shank 8 axially slidable in a spindle 1 which is eccentrically located in a carrier 5 rotatable about a central axis M by a driving shaft 6. A bevel gear 2 attached to the spindle 1 rolls on 'an internal bevel gear 4 integral with a stationary outer casing 3. The axis A of the spindle 1 is arranged at an angle a to the axis M so as to give the effect of a cone with apex at K, the point of intersection of the axis A and M, rolling inside an outer cone, and the generating point'S of the cutter is thus external to the rolling circle whose radius is represented by the perpendicular distance between the axes A, M in the plane of rotation of the cutting point. Axial adjustment of the shank 8 brings the cutter to the correct position for producing the best approximation to a straight sided polygon and may also be used to compensate for inaccuracies of the mechanism such as play in the bearings &c. The number of sides in the polygon produced is determined by the ratio of the gear 4 to the pinion 2, a ratio of 3 : 2 giving a triangle and a ratio of 4 : 3 a square. In order to produce a bore tapering either inwards or outwards towards the base the cutter 9 may be secured in a carrier 10, Fig. 2, slidable in guides 12 in the spindle 1 which are arranged at an angle B to the axis M, a line parallel to the guides passing through the cutting edge S and also passing through the intersection K of the axes A, M. Movement of the carrier 10 to produce the taper is caused by axial movement of a rod 15 having a pin 17 engaging a hole in the carrier. In another taper boring construction the cutter 9 is secured in a carrier 11, Fig. 3, movable along inclined guides 13 by a pin 18 on an axially displaceable rod 16, In the construction of Fig. 2, the cutter is arranged above the point K and in Fig. 3 below the point K, the latter being preferable for deep bores. Similar polygons of different size may be produced with the apparatus of Fig. 1, by adjusting the tool-holder 8 along the axis A and moving the cutter point radially so as to preserve the same ratio of distances of the cutter point from the axes A, M. The radial adjustment of the cutter is secured by means of a wedge &c.
