Title: Improvements in or relating to electromagnetic vibrating devices, especially for sound transmitters
IPC: G01S1/72
Filed: 1921-01-28
Abstract: 178,235. Kunze, W. Jan. 28, 1921. Subaqueous audible signals.-In an electromagnetic vibrating device for subaqueous sound transmitters in which an alternating current system vibrates in a constant magnetic field or produces an alternating field in which a continuous current conductor vibrates, the alternating current system consists of two coils wound in opposite directions, one coil of which receives current impulses during the positive half-period, and the other during the negative half-period so that the frequency of the vibrations is double that of the alternating current. The conductors Sp<1>, Sp<2> are rigidly attached to a diaphragm M and surround the core K of an electromagnet F which is energized' by a coil G carrying continuous current. If alternating current is supplied by an alternator, a commutating device may be rigidly attached to the shaft, Fig. 2. This device consists of a conducting disc S having half as many contact segments C<1>, C<2>, C<3> as the generator has poles, the intermediate spaces D', D<2>, D<3> being filled with insulating material. Brushes B<1>, B<2> connected to the coils Sp<1>, Sp<2> are so arranged that when one brush is on a contact segment, the other rests on an insulating segment, the time during which such contact is made coinciding with half a period of the alternating current. The distribution of the alternating current impulses may be effected by means of two current rectifiers, the coils Sp', Sp<2> being connected to the anode and cathode respectively either directly or through a transformer. The invention is particularly adapted for submarine sound transmitters in which case the provision of a special high frequency transformer is unnecessary as the usual ship's transformer of moderate frequency for wireless telegraphy may be employed.

Title: Improvements in or relating to correcting devices for soundlocating appliances
IPC: G01S1/72
Filed: 1932-02-06
Abstract: 396,715. Locating sounds. LEKARSKO TECHNICKY PRUMYSL AKC. SPOL. and HARLAS, J., 80, Kralovska Tr, Kralin, Prague. Feb. 6, 1932, No. 3621. Convention date, Feb. 7, 1931. [Class 118 (ii).] A correcting device for use with soundlocating apparatus comprises a lamp controlled to project the path of a sound source, corrected for temperature and wind-velocity errors, into the interior of a spherical surface coated with a layer of light-sensitive material. A device is also described whereby the path so recorded may be corrected, by extrapolation, for the speed of the sound source. The apparatus may be connected directly to a sound-locating device or may have results obtained from such a device transmitted to it by known means. An arm 1 is moved about an axis b, to take up the apparent altitude angle of the sound source. An arm 3 is connected to a slidable sleeve on the arm 1 and has pivoted to it a link 4 the length of which is proportional to the velocity of sound at the normal temperature. The lower end of the link 4 is attached by a universal joint to a block slidable along an arm 2 pivoted at z. The block is adjusted along the arm 2 a distance corresponding to the wind velocity w and, another member 5 is adjusted along the arm in the opposite direction a distance kw, where k is a known constant. The member 5 is connected through a parallel linkage to a point l<1>a on a link which is pivoted to the arm 3. This link carries a lamp at the point l<1>a the beam from which is projected on to a light-sensitive spherical surface S rotated about the centre point b to follow the apparent azimuthal movements of the sound source. The air temperature is taken into consideration by manually adjusting the distances w and kw in accordance with formulµ given in the Specification. The point l<1>a may be situated some distance above the central plane of the hemisphere. In order to correct for the speed of the sound source, the device shown in Fig. 7 is employed. An arm 11 is pivoted to rotate about a diameter of the spherical surface S and carries two sliders 13, 16 bearing indicating marks. The sliders are maintained by a screw 12 at an adjustable distance e apart, e being proportional to the known or estimated sound-source speed. The slider 16 is connected by a link 14 to an arm 15 secured to the arm 11. The slider 13 is caused to follow the path recorded on the spherical surface, the slider 16 then indicating the path as corrected for the speed of the source.

IPC: F01L13/00
Filed: 1917-03-14
Abstract: 104,879. Claudel, C. H. March 15, 1916, [Convention date]. Regulating.-To maintain a suitable compression at all speeds, (1) the normal admission valve may be controlled conjointly with a throttle valve in the inlet pipe, so that as the throttle opens, the closing of the admission valve is delayed to permit a portion of the charge to be rejected during the compression stroke, (2) the normal exhaust valve may work in conjunction with a throttle valve in the exhaust pipe, so that as the throttle valve closes, the period during which the exhaust valve is held open is reduced, thus retaining more or less of the combustion gases in the cylinder, (3) the methods described in (1) and (2) above may be combined, the throttle valves in the inlet and exhaust pipes being connected together to move in unison, or (4) a throttle valve may be located in the exhaust pipe to restrict the outlet passage more at less at low speeds. In the arrangement shown in Fig. 1. throttle valves 2, 9 in the inlet and exhaust pipes respectively are connected together by a rod 12. Connected to the links 13 for controlling the throttle valves are distance-pieces 4, 7, which are inserted between the stems of the inlet and exhaust valves and their actuating-cams to vary the timing. A pipe 14 conveys combustion gases to a carburettor or vaporiser.

Patent GB-565731-A (GB)
Title: Improvements in and relating to the differential saponification treatment of cellulose ester materials
IPC: D06M11/38
Filed: 1943-03-10
Abstract: Cellulose ester materials are differentially saponified by subjecting local areas to pressure and thereafter treating the materials with a saponifying agent, whereby the subjected areas saponify more readily than those not so treated.  Pressure is applied by means of embossing rollers or plates.  Alternatively, the material in conjunction with a woven cloth may be subjected to the pressure of plain rollers so as to impress the pattern of the cloth upon the material. Saponification may be effected, for example, by a 0.9 per cent solution of caustic soda at room temperature.  The invention is suitably applied to cellulose acetate in the form of fibres, staple fibres, films and woven or knitted materials, and the treated materials may be dyed with a mixture of dyestuffs (e.g. Dispersol Fast Yellow A and Chlorazol Sky Blue FF) to produce a differential dyeing effect upon them. The materials may be treated prior to the application of pressure, with a hot salt setting solution.

Title: Improvements in and relating to apparatus for filling containers with liquid
IPC: B67C3/08
Filed: 1957-02-06
Abstract: 817,824. Bottling. MEYER LIQUID Ltd., and FRIENDSHIP, K. F. M. Feb. 5, 1958 [Feb. 6, 1957], No. 4048/57. Class 125(2). In a counter-pressure, revolving table bottle filling machine the liquid valve 9 is controlled by a displaceable actuating member 10, to one side of which counter-pressure air or gas is supplied, air or gas under pressure from an external source being admitted, to the other side of the actuating member 10 so that if the counter-pressure falls the liquid valve 9 is closed. Counter pressure gas is supplied from a source 25 through a piston valve 29, operates by a cam ring 33 abutted by a roller 32 carried by the piston 29, and a non-return valve 28 to a chamber 15a in the filling head 1. The bell 8 is raised by the bottle to seal against ring 22 and to raise valve member 16 allowing entry of counter-pressure gas to the chamber 15a. The liquid pear valve 9 seals against the lower end of filling tube 7 supplied from liquid tank 2 by syphon pipe 6, and is carried by a rod 9a depending from a piston-like actuating member 10. A passage 39 puts chamber 15a in communication with space 40 above the actuating member 10. Air or gas from supply pipe 15 is fed around the lower reduced diameter portion 11 of member 10 through passage 14. On a predetermined difference in pressure between counter-pressure air or gas and air supplied to beneath member 10 the liquid valve 9 is closed. The air in supply pipe 15 preferably has a controlled bleed to atmosphere and on this difference in pressure being recognized as e.g. by the apparatus described in Specification 817,823, the bleed is stopped and the increase in pressure in pipe 15 is sufficient to raise actuating member 10. Snifting is controlled by the abutment of piston valve 42 against a cam ring 43 fixed to the supports of the revolving table. Instead of a single supply pipe 15 there may be two, operating at different pressures and connected to beneath the actuating member 10 at different times in the filling process. Specifications 514,200 and 650,454 also are referred to.
