[Classes 83 (ii) and 83 (iv)] [See also Group XVI] Cupped articles with pleated sides and curled rim, e.g. as in Fig. 4 are made in one vertical motion from a coiled strip 25 which is pulled step-by-step past dies. The circular knife 32 cuts out a disc from the strip, the punch 60 descends to draw it down between rings of fingers 40 and 39 to pleat it and then to complete the cup in a matrix 45. On this descent the cup passes through a ring of opened segmental curling dies 41 which, on the upward return of the cup, close in so that the cup edge 62 engages them and curls itself round in the space 63. The fingers 40 are first pressed in to form a preliminary pleating and co-operate with the fingers 39 as described in Specification 435,783, [Group XVI]. The crank-shaft 1 operates the punch 60 and also actuates a series of cams and tappets to operate the ring cutter 32, the sector-moving levers 44 and the ejector 48. The feed rollers 27, the top roller of which is driven by belt from the crank-shaft draws the strip through the machine, a disengaging coupling 56, cam operated, interrupting the feed during forming of the blank.

Filed: 1957-11-15
Abstract: 846,319. Lighting fittings for tabular lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 15, 1957 [Nov. 20, 1956], No. 35663/57. Classes 75(3) and 75(4). In a light fitting comprising a cylindrical optical element such as the parabolic reflector 11, Figs. 3 and 4, and an elongated light source, in order that the light source, which is not always coaxial with its lamp envelope, maybe located coaxially with the focal line A-A of the mirror the support for the lamp holder 12 is made adjustable relative to the mirror about an axis parallel so the said focal line, so that the centre line of the said envelope is spaced from the focal line of the mirror e.g. by an amount b equal to the displacement of the light source from the axis of the envelope, for example as the discharge path is displaced from the axis of the envelope in an electric discharge tube having electrodes arranged centrally within the envelope. In order to correct discrepancies in the position of the light source resulting from cementing the envelope obliquely in the cap or the like, the holder for the envelope cap is tiltable relative to its support. As shown, the holder 12 is mounted on a support 13, so that the axis of the holder which coincides with the axis B-B of the envelope 2 of the tube, extends parallel to and at a distance b from the axis A-A of the mirror 11. The support 13 including the cylindrical portion 14 is rotatable about the axis A-A in an opening in the side wall 6 of the housing of the fitting comprising the side walls 6, 7, a rear wall 8 with a curved upper part and a lower straight part and a bottom wall 9. A drilled nut 13b permits the support 13 to be locked in the presented position in the wall 6. The holder 12 is mounted on a plate 16, Fig. 5, by three equally spaced bolts 18, 19, which carry respective springs 18a, 19a to push the plate 16 away from the cap 17, the bolts 19 being adjustable from without by a suitable tool to tilt the plate about the bolt 18. The housing 6, 7, 8, 9 is tiltable in a vertical plane about pivots 21, 22 in a forked member 20 rotatably adjustable on a stand 25 in a horizontal plane.

Abstract: 418,546. Copy-holders. DODDS, N., 1516, 44th Street, N.W., Washington, U.S.A. Dec. 19, 1933, No. 35776. [Class 100 (iii).] A copy-holder comprises a scroll-shaped paper-retainer 14, which is pivotally mounted at its upper edge on a supporting casing 10, so that it can be tilted up to give access to the parts beneath. The scroll is open at both ends, so as to receive a sheet of any width. The top of the sheet passes over a substantially vertical extension 14<a> of the scroll, on which it is held down by a pivoted weighted member 19. The top edge of the member 19 serves as a line-indicator, and the member can be turned back to form a funnel-shaped entrance for the sheet. The paper is fed by a roller 25 carrying indiarubber rings, which project through apertures in the part 14<a> of the scroll, so that the paper is pressed against them by the member 19. The rings are held in grooves formed in the surface of the roller, which is provided with conical ends to facilitate the application of the rings. The roller is braked by a spring 41, and is rotated by a ratchet-wheel and a pawl 27, which is pivoted at its lower end to a lever 33 provided with a finger-piece 35. The pawl is drawn rearwards by a spring 36, so as to bear against the ratchet-wheel. The stroke of the lever 23 can be varied by means of a rotatable cam 37 having three steps, so as to adjust the feed for single, double, or treble spaced lines.

[Also in Group XXVIII] The movable carriage of a machine for drawing pipe or rod through stationary dies 3 has at least two sets of gripping jaws 18, each set being independently operated by pneumatic cylinders 45 and the jaws being fitted in guideways 20 sloped so that the jaws are forced into secure engagement with the blank ends 4 during movement of the carriage in the drawing direction. The drawing carriage 1 is reciprocated by a chain drive connected at 12 and 16 and moves on rails engaged by wheels 6, 9 arranged at right angles to each other. The jaw operating cylinders 45 are connected to the bore of a sleeve 49 on the carriage and at the forward end of the carriage stroke, the sleeve telescopes over a nozzle 62 mounted with some degree of freedom on rubber pads 65 on a control valve 55; when the sleeve and nozzle are in sealing engagement, a cam 54 opens the valve to supply air to the jacks and retract their piston rods 44 against the action of springs 41. Upper arms 32 of levers operated by the jacks then withdraw spring-loaded pins 27 from elongated slots 26a in the jaws and lower arms 31 push the jaws forward to engage the blank ends. Movement of the carriage in the drawing direction moves the jaws further towards each other to grip the blank ends securely even when the nozzle 62 disengages from the sleeve 49 and the piston rods are extended by the springs 41. At the end of the drawing stroke, as the ends of the blanks leave the dies, the blanks shoot forward, thus automatically opening the jaws, and are deflected downwards by a sloping plate. During the drawing movement, the ends of the pins 27 bear against the sides of the jaws, but, after release of the jaws, they snap into the slots 26a to hold the jaws in open position.

Abstract: 838,280. Humidity controllers and indicators. TEDDINGTON AIRCRAFT CONTROLS Ltd. Nov. 10, 1958, No. 36024/58. Class 40 (1). [Also in Groups XXXV and XXXVI] A means for obtaining and utilizing a signal representative of a change in relative humidity from a predetermined value comprises a pair of temperature-sensitive resistors responsive one to a wet bulb temperature and the other to a dry bulb temperature, each of the resistors being incorporated in a respective bridge circuit and the output of the two-bridge circuits being con. nected in a common output circuit the ratio of the energizing voltages of the two bridge circuits being such that no output signal is given when the relative humidity has a predetermined value. Fig. 1 shows a wet bulb resistance Rt1 and a dry bulb resistance Rt, each in a bridge circuit. One bridge is excited directly from a transformer IT and the other from the same trans-. former via a potentiometer E, the outputs of the bridge circuits are connected via the primary of an output transformer OT. The position of potentiometer E determines the relative humidity at which no output is given. The output from the output transformer may be used via an amplifier either to control a humidifier to restore the humidity to its predetermined value or to control an indicator device and to move potentiometer E so as to rebalance the outputs from the bridges and allow the indicator to remain in its displaced position. An arrangement of the device in a box together with a means for keeping Rt1 damp is described with reference to Fig. 2 (not shown). It is stated that the device may be A.C. or D.C. operated. The potentiometer E may be temperaturesensitive so as to provide some temperature correction for the inaccuracies which arise in the use of the mathematical hygrometic relation between the measured temperatures and the relative humidity.
