Inventor: SOUTHWELL RICHARD VYNNE
IPC: G01F23/18
Filed: 1916-03-17
Abstract: 124,769. Southwell, R. V. March 17, 1916. Order-type apparatus.-Apparatus for indicating at a distance the head of liquid in a vessel 4, for example the petrol tank of an airship or aeroplane, comprises an outer chamber 1 communicating with the liquid and a pair of concentric tubes 5, 6 between which the liquid forces up a column of mercury or the like 9, so as to make contact with a series of studs 7 connected to the indicator 10. The chamber 1 is screwed into the base of the vessel 4, and the inner tube 5, formed of insulating-material and open at each end, is screwed into the lower neck of the chamber 1. The outer tube 6 is closed at its upper end and passes loosely through the upper neck of the chamber 1, and its lower end rests on the base of this chamber, slots 8 allowing communication with the annular space 11 between the tubes. Mercury or other conducting-liquid 9 is placed in the base of the chamber 1 and is forced into the annular space 11 by the head of liquid in the vessel 4, thereby making contact successively with a series of contact studs 7 in circuit with numbered or coloured lamps at the indicating-station. One or more handswitches may be provided at the indicator, so that the liquid depth may be ascertained by trial. The indicator may comprise a pointer moving over a dial. The lowest contact stud may be always covered by the mercury so as to provide a test circuit, When the vessel 4 has a pressure feed, the upper end of the outer tube 6, which communicates with the mercury column through slots 8', is connected to the upper part of the vessel. If the liquid yields inflammable vapour, a layer of heavy oil is floated on the mercury column in order that sparking at the contacts 7 may not reach the vapour. The restricted communication allowed by the slots 8 and at the top of the chamber 1 prevents surging of the liquids within the apparatus.

Title: Improved method of and apparatus for determining the out-of-balance of rotors
IPC: G01M1/22
Filed: 1941-03-26
Abstract: 546,509. Testing balance of rotary apparatus. ARNOLD, R. N., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 26, 1941, No. 4041. [Class 106 (ii)] The rotor surface is provided with a dark or light band to contrast with the remainder of the surface and is mounted in a vibrating system so that when the rotor is rotated to produce resonance, an incident beam of light is reflected from the rotor surface through an aperture also synchronously vibrated to produce on the screen an illuminated area which is a measure of the amplitude and a superimposed dark or light band the position and direction of movement of which gives the phase displacement between the reference position and the out of balance force. The rotor 1 to be tested is mounted with its axis vertically in brackets 2, 3 forming part of a frame 4 adjustable vertically in a main frame 5 of U-shape. A torsion bar 6 rigidly attached to one limb of the frame 5 is held at the other end in a bracket 7. By means of a screw release 8 the unsupported length "x" of the bar 6 can be adjusted The other limb of the U-frame 5 is fulcrummed by a leaf-spring fulcrum 9 on the stationary mounting 10. The frame 5 is extended transversely of the bar 6 to form a lever 12 carrying a light shield 13 formed with a horizontal slot 14. The periphery of the rotor has a highly-polished surface all round except for a reference strip of non-polished surface at one place for a reference point. The light and dark surfaces may be arranged oppositely. Light from a source 17 passes through a condenser lens 18 to the rotor surface and is reflected back through a condenser lens 19 and the slot 14 through an objective lens 20 to a screen 22. The incident and reflected beams are arranged to lie substantially in a plane passing through the rotor axis and perpendicular to the torque rod. With the rotor rotating and the torsional system oscillating at or near resonance, an image is produced on the screen 22 in the form of a band the depth "d" of which depends on the amplitude of the torsional vibration, the length of lever 12, and the magnification of lens 20. Superimposed on this is a dark line P indicating the reference band. The depth "d" is utilized as a measure of the amount of out-ofbalance while the position of the line P and its direction of movement are utilized to give the " phase of the out-of-balance.

Title: Improvements in or relating to lamps for vehicles
IPC: B60Q1/14
Filed: 1936-02-13
Abstract: 470,348. Vehicle lamps; mounting reflectors and electric lamps in lanterns. MACINTYRE, N., PEILL, D. M., and FOOTE, A. Feb. 13, 1936, Nos. 4333 and 8750. [Classes 75 (ii) and 75 (iv)] In a vehicle lamp, a rotatable carrier 10 carries a pair of supplementary reflectors 11a, 12a each shaped to fill a central opening in and complete the curvilinear continuity of a main reflector B, separate light sources 11, 12 are carried by the supplementary reflectors in different relationships thereto so that two alternative beams of different character are obtainable, the carrier is rotatable alternately in reverse directions to change the supplementary reflector in use, and co-operating contacts in the lamp casing A and on the carrier 10 automatically make and break the circuit to the two light sources as the reflectors are brought into and out of operative position. The reflector 11a and/or the light source 11 may be amber-coloured or otherwise coloured, and the reflector 12a is colourless. The light source 11 is arranged so that the reflector 11a gives a diffused beam. Movement in one direction is transmitted from the Bowden cable 17 to the carrier by step-up gearing 18, 19, and a spring operates in the other direction. The electric contacts carried by the casing are spring-plungers which hold the carrier in position after rotation. In another form, the axis of rotation is inclined, and the carrier can be moved to a third position in which one of the auxiliary reflectors projects its beam to one side and downwardly. In another form, the main reflector B is also rotatable to one side as shown in Fig. 6. The auxiliary reflector 29 has a projection 55 which engages the reflector B so that the reflectors 29, B can be deflected together. The reflector B is carried by arcuate arms 53 movable in brackets 54. Alternatively, the reflector B may be guided by pin-and-slot or groove means. One of the supplementary reflectors may be formed of upper and lower half-paraboloids, the focus of the upper half being at the light source, and that of the lower half in front of the light source. The upper half of the lamp bulb may be blacked or hooded, or screened so as to reflect light onto the lower half of the reflector. The carrier may be moved by electromagnetic means.

Filed: 1941-04-01
Abstract: 548,389. Glucose. CORN PRODUCTS REFINING CO. April 1, 1941, No. 4388. Convention date, July 13, 1940. [Class 127] The process of producing dextrose by hydrolysis of starch or of the polysaccharides which occurs in the first greens or hydrol after crystallization of dextrose from starch-conversion liquors, is carried out as a continuous process by heating the liquid to be converted, e.g. starch suspension of 10-24‹ Be mixed with a smaller proportion of acid than usual, by passing it in atomized or divided form through a body of steam of at least 100 lb. per sq. in. pressure, collecting the heated liquor at the base of the vessel and passing it as a stream at a velocity such as to prevent deposition of collodial matter. The starch suspension may be heated to form paste before conversion by passing into steam at a lower pressure. The hydrolysing acid may be volatile e.g. sulphurous acid. Starch and acid mixed in a vessel 11 are forced by a pump through a nozzle 14 and against a splash plate 15 into a vessel 10 supplied with steam through pipe 18. The heated liquid collects in the base of the vessel and passes downwards through it to a throttle valve 20 which allows discharge into a flash chamber 21 from which the converted liquor passes through a steam trap 23 to a neutralizing vessel 24. The steam from the flash chamber 21 may be used for pasting the starch suspension.

Filed: 1944-03-09
Abstract: 588,030. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd., and WEST, R. A. March 9, 1944, No. 4426. [Class 38 (iii)] In a control system for a polyphase induction motor of the slip-ring type, the motor is brought to rest by opening the main contacts 3 and closing the braking-contacts 7, and approximately at the same time inserting the resistance 4 in circuit with the rotor winding 2. Consequently, one stator winding is short-circuited, and the voltage applied to another reversed, thereby producing a magnetic field greater than normal and a powerful braking-effort. The contacts 7 may open, under the control of a timing-relay, after a period sufficient to enable the motor to come to rest. Interlocks ensure that the contacts 3 and 7 are not closed together. The Specification describes also the application of the invention to a two-phase motor with a threewire supply, a two-phase motor with a fourwire supply and a three-phase motor with its primary connected in star. The rotor windings can be connected in either star or mesh. An automatic sequence control subject to stop and start push-button switches is described.
