Abstract: 771,084. Electric control systems. BENDIX AVIATION CORPORATION. Feb. 3, 1955 [Feb. 8, 1954], No. 3233/55. Class 40 (1). [Also in Group XL (b)] In a photo-electric device for giving an electrical output indicative of the position of a magnetic compass card in which the card has a pair of radial light interrupting edges, the beam is so directed as to be interrupted by both edges in response to relative rotation of the card and its frame. As shown, light from a source 25 is directed past an edge 22 of a card 21 shaped as shown in Fig. 5, is reflected by mirrors 30, 31, 32 and is redirected upwardly past another edge 23 of the card on to a photo-electric cell 35 which provides an output signal. The effect of the reflecting mirrors is to cause opposite sides of the beam to be cut by the two edges of the card so that the change of light reaching the cell when the card rotates is doubled. The card is mounted in a bowl of liquid and the mirrors are mounted below the bowl although they may be inserted in it. The compass is mounted on gimbols 13, 14 and a bracket 15 and may be driven through a flexible drive 18 and gearing 16, 17. In the modification described with reference to Figs. 6, 7 (not shown), and 8, the intermediate mirror corresponding to mirror 31 of the arrangement already described is mounted inside the bowl. Further the compass card edges 46, 47 are spaced radially so as to allow 180 degrees of rotation of the compass without giving a false reading, while in the arrangement of Figs. 9 and 10 (not shown), the light interrupting edges are formed diametrically opposite on the card and two mirrors only are necessary.

Abstract: 731,553. Teeth cleansing douches. MEYER, O. E. Feb. 5, 1953 [Feb. 7, 1952; Nov. 17, 1952], No. 3303/53. Class 81 (2). In an apparatus for cleansing teeth or other parts of the body, a stream of liquid containing nascent carbon dioxide is produced. In the simple embodiment shown in Fig. 1, air is compressed by a pump 5 into a storage tank 4. It is then led to a cock 24, which is divided into three parts, so that air flows from pipe 23 to pipes 26, 27 simultaneously. Pressure is accordingly introduced into cups 19, 20 which hold tartaric or citric acid and sodium bicarbonate solutions respectively. The liquids are consequently forced up tubes 28, 29 through the main cock 24 and individual control valves 47, 48 to jets 51, 52 in the hand piece 35 where they separately mix with air coming from pipe 26 and subsequently pass through nozzles 38, 39, by means of which they are brought together immediately before passing through the outlet nozzle 41. The nozzle 41 may carry a brush 42 and, for convenience, the control valves 47, 48 may be built into the hand piece. In a modified form'of hand' piece, see Fig. 11 (not shown) the liquids and air supply are led to a conical nosepiece in the surface of which the jets are formed as grooves, their effective cross-sectional areas being determined by a conical, surrounding sleeve, the axial position of which may be varied as required.

Title: An improved method of and apparatus for plastically shaping materials, more especially by extrusion
IPC: B21C31/00
Filed: 1953-02-06
Abstract: 728,784. Automatic control systems. MUNKER, T. Feb. 6, 1953 [Feb. 15, 1952], No.3379/53. Class 38 (4). [Also in Groups XXII and XL (b)] In a method of plastically shaping materials, more especially by extrusion the workpiece after deformation passes through a substantially closed chamber 7 where the radiation emanating from the workpiece is passed through an optical system to a device responsive to heat radiation, the output from which device is used for the control of the conditions of the process determining the heat radiation of the deformed workpiece. In an extrusion process the speed of extrusion is preferably controlled so that the temperature and hence the heat radiation of the, extruded workpiece leaving the extrusion die 4 is maintained substantially constant. The chamber 7, Fig. 3, is lined with bright aluminium 17 to reflect the radiation through a pair of lens 14, 15 which direct it through a revolving slotted disc 27 to a photo-cell or photo-electric resistance 16. The latter also receives through the slotted disc, a standard or comparative radiation from a standard radiation device 21 consisting of an electrically heated body controlled by a resistance 24. A movable diaphragm or filter 22 controls the standard radiation and a lens 23 directs it through the slotted disc to the photocell 16. The latter therefore receives alternate radiation impulses from the chamber 7 and the standard device 21 and thus generates electric impulses which are passed through a three-stage amplifier and phase discriminating circuit, Fig. 4 (not shown). The output of the latter controls through a relay 36, Fig. 1, a servomotor 37 which in turn controls the water pressure valve 33 of a hydraulic extrusion press 1 and thus the speed of extrusion. A device 32 connected to the output of the phase discriminating circuit indicates any difference between the chamber radiation and the standard radiation whereby an operator may control the valve 33 manually to maintain constant the temperature of the workpiece. A recording device 40, for the speed of extrusion and the temperature of the extruded work-piece, and optical or acoustical alarm signals 39 are also provided. The measuring head 13, Fig. 3, containing the radiation detecting equipment is surrounded by a water jacket 19. The extruded work-piece 8, Fig. 2, which is preferably of aluminium or aluminium alloy is tempered by water issuing from an annular jet 41. A cushion of compressed air from an annular jet 42 projects the chamber 7 from water vapour.
