Title: An improved method of and apparatus for determining the deviation of a compass
IPC: G01C21/00
Filed: 1920-08-09
Abstract: 171,165. Prati, F. Aug. 9, 1920. Angle-measuring instruments. - An instrument for ascertaining the deviation of a ship's compass and also applicable as a station pointer comprises a graduated circle divided into quadrants by strips XX<1>, YY<1> and having a central hole through which a pencil &c. can be passed. Alidades A, B, C are pivoted at the centre of the circle and a slider K can be adjusted around the graduated rim. To use the instrument the bearings of three objects on shore are taken by the compass and the alidades are set to the observed bearings. The instrument is placed on the chart and moved until the edges of the alidades pass through the corresponding points on the chart. The centre of the circle then represents the observer's position and the orientation of the strip YY<1> with respect to the meridians, decreased by the known variation at the point of observation, gives the required deviation. To facilitate the determination of the orientation, the circle is marked with reference marks or signs, represented in Fig. 4 by the numerals I-IX arranged in each quadrant in such a way that a given sign occurs at equal distances from the axis of the strip XX<1> and also at equal distances from the axis of the strip YY<1>. The instrument may itself be used for taking bearings, in which case the alidades are provided with hinged sights F<1>, F<2>, F<3>, and the instrument is used in conjunction with a baseboard having a central sighting-pin L, Fig. 2, adapted to pass through the central hole 0 of the circle. The board also has pins P, P<1> between which the slider K just fits, and is mounted on the ship so that the line through L bisecting the line P, P<1> is parallel to the fore-and-aft line of the ship. The slider K is first set to a position corresponding to the ship's course by compass, and the instrument is placed in position on the base board. Bearings axe taken by means of the sight L and sights F1, F2, F3, and the instrument is then transferred to the chart as before. If the instrument can be set to a known orientation, the ship's position can be found by sighting two objects only.

Title: Gas mixture laser
IPC: H01S3/03
Filed: 1970-05-15
Abstract: 1298748 Lasers RCA CORPORATION 15 May 1970 [27 May 1969] 23666/70 Heading H1C A gas laser pumped by a discharge in the active medium has two oppositely directed magnetic fields applied transverse the direction of the discharge current in the medium to increase the output power. The active medium is a mixture of a carrier gas such as He which forms a plasma in response to an applied voltage and a laserable gas such as Cd vapour which is excited by the ionized carrier gas. In the known single field laser of Fig. 1, the discharge tube 10 has Brewster windows 18, 20, which give a plane polarized output, and the magnetic field is applied in a direction parallel to the electric vector of the output. The output is increased according to the magnitude of the field, Fig. 6 (not shown). This increase is attributed to movement of the plasma 28, Fig. 2, to one side of the discharge tube under the influence of the field, for the plasma then loses ions to the tube wall and the impedance of the plasma rises. There is a consequential rise in the voltage applied to the tube, and segregation of the carrier and laserable ions occurs, some of the latter ions escaping from the plasma to the central regions of the tube where stimulated emission is likely to occur. The movement of the plasma, while increasing the output, distorts the output beam. This is compensated in the invention by using two or more magnetic fields spaced along the tube, the fields being transverse the plasma current but oppositely directed.

Title: Improvements in and relating to electric self starters for the engines of motor vehicles
IPC: F02N11/08
Filed: 1925-09-24
Abstract: 250,106. Soc. des Appareils Magondeaux. July 30, 1925, [Convention date]. Addition to 249,935. Starting prime movers.-The electric starter described in the parent Specification is modified by arranging the electrical connections for control by a single contact member 25 brought into engagement with contacts 33 by the axial movement of the driving pinion 13 and armature 21 of the electromagnet. As before, a disc in sliding connection with the shaft 12 of the pinion 13 is braked by an electromagnet having two coils 19, 20. The coil 19 is in series with the motor armature 3, field coils 2, battery 28, and hand switch 27, and the coil 20 is in parallel with the motor. On closing the switch 27, the shaft 12 is braked by means of the electromagnet 19, 20 and moves axially to bring the pinion 13 into engagement with an engine gear. The resulting movement of the armature 21 closes the contacts 25, 33 and connects the motor brush 5 directly to earth, so that the coil 19 is cut out of the motor circuit and the motor rotates at full speed. Current still passes through the coil 20, so that the electromagnet holds the member 21 in position for closing the contacts 25, 33 until the switch 27 is released, when current passes through the coils 20, 19 in series; these coils now oppose one another and the armature 21 is released and returned by a spring to its initial position. The contact 25 is so constructed that sparking only takes place upon a removable spring-pressed member, to ensure a clean contact surface.

Title: Improvements in and relating to carpets
Inventor: SMITH JOHN OLIVER
IPC: D06M11/38
Filed: 1957-08-01
Abstract: The appearance and handle of carpets containing pile yarns consisting of crimped viscose rayon staple fibres are improved by treating them in the grey state with a swelling agent and then removing the swelling agent from the carpets.  In a modification of the process, yarns consisting of crimped viscose rayon staple fibres are treated with a swelling agent which is then removed and the yarns are incorporated into a carpet, the treatment serving to develop additional crimp in the yarn and also to set the twist. The treatment may be carried out on yarns with special twists to obtain crepe and boucl<\>ae effects.  The swelling agent may be a dilute solution of a caustic alkali, e.g. a 0,5-7% by weight solution of caustic soda, which may be removed after a treatment time of 1-15 minutes by washing with hot water, acidifying with dilute acid, e.g. acetic acid, and then washing until acid-free. The carpet may subsequently be dyed.  The Provisional Specifications refer to the treatment of yarns composed wholly or partly of crimped viscose rayon staple fibres before or after incorporation into a carpet.
