Title: Course-indicating light beacon
IPC: B63B22/16
Filed: 1956-09-14
Abstract: 806,793. Light beacons for marine navigation. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Sept. 14, 1956 [Sept. 28, 1955], No. 28147/56. Class 118 (2). A course indicating beacon intended primarily for use as a marine navigation aid comprises two sources of light 10, 11 which are screened to be visible from points within a first (26, 27) and a second (28, 29) sector respectively of the surroundings of the beacon, the two sources being adapted to emit distinguishable radiations and form of signal groups made up of different numbers of equal length signals, and the two sectors being arranged to overlap in a common, narrower sector 27, 29 which includes the course line and from points within which both sources are visible. The two sources may additionally be distinguished by the use of light of different colours. As illustrated the sources are comprised of electric lamps which are connected in circuit with cam-operated contacts, 22, 23, so as to radiate respective intermittent signals which are complementary to each other, such as the morse letters O (three dashes) and T (one dash). From points within the common sector a continuous succession of dashes is seen. Cams 24 and 25 for operating the contacts are driven by a motor 21. Further cams and contacts 36, 37 are provided to permit the periodical transmission of identification signals, K (dot, dash, dot) and H (four dots) as illustrated, the connections to the cam contacts being changed over by a clock-controlled switch 34, 35. One edge 26 and 28 of each of the sectors is defined by a screen 13, 14, whilst the other edge 27 and 29 is defined by a screen 18 supported at right-angles to a central screen 15 extending forwardly of the light sources. The width of screen 18 determines the width of the common sector. In a modified beacon, Fig. 3 (not shown), screen 18 is constructed with a pair of hinged plates which may be turned by an electromagneticallyoperated mechanism to change the effective width of the screen and hence the width of the common sector. This facility is provided to permit the beacon to operate alternately with a wide and a narrow common sector to define the course line. Synchronously with the changeover, the complementary code signals are also changed. The sources of light 10 and 11 may be mounted at different levels, Fig. 5 (not shown). Spare light sources may be provided which are brought into operation by thermorelays in the event of failure of the main sources, Fig. 6 (not shown). Two spaced beacons with intersecting fields of operation may be used to define areas and a course line including a change of direction, Fig. 4 (not shown). A light beacon according to the invention may be combined with a similar complementary-code type of radio beacon, the two beacons being arranged to define the same course line and being operated synchronously.

Abstract: 759,338. Theft alarms on motor vehicles. HANEL, G. Oct. 1, 1954, No. 28315/54. Class 118(1) [Also in Group XXVII] A motor vehicle having an ignition circuit is protected from theft by an alarm and ignition cut-out system (see also Group XXVII). The system comprises a combined door lock and cross connecting switch 1 which in the door locked position connects the terminals 1b 1a and interrupts the ignition circuit but sets the alarm circuit through ignition switch 8, fuse box 7, terminals 1b, 1a, sonic alarm 4 and door and boot switches 10a, 10b, 10c, so that if a door or the boot is forced open the appropriate switch 10 is made to complete the alarm circuit. In the unlocked position of lock switch 1 the terminals 1c, 1d are connected instead, thus neutralizing the alarm circuit and completing the ignition circuit.

Abstract: 974,245. Negative resistance pulse regenerators. STANDARD TELEPHONES & CABLES Ltd. Aug. 4, 1961, No. 28475/61. Heading H3T. [Also in Division H1] A pulse transmission line constructed as a cable (see Division H1), the equivalent circuit of which is shown in Fig. 2, comprises negative resistance elements 16a-16d with the V-I  characteristic shown in Fig. 1 and operates as follows. Bias voltage V c  is applied across lines 13, 14 to charge up capacitors 10a-10d. On receipt at 15a of a pulse of sufficient magnitude to raise the voltage across element 16a to Vt, the element is triggered to its low resistance state and discharges capacitor 10a, giving rise to a pulse which via coupling capacitor 17a triggers the succeeding negative resistance element 16b and so on. To prevent reflection of pulses the recharging time of capacitors 10 is arranged so that each one is not sufficiently recharged for triggering until the pulse has been transmitted through at least two succeeding stages. The line may be branched, and may be made to operate as a delay line, a pulse shaper or a form of data store.

Filed: 1970-06-12
Abstract: 1293062 Knitting machines J P STEVENS & CO Inc 12 June 1970 [16 June 1969] 28518/70 Heading D1C A yarn or the like is threaded alternately round uniformly spaced pulleys 8L, 8R on the outer loops of two endless diverging chains 5L, 5R so as to form a zig-zag configuration of yarn which is forwarded and gradually extended until the yarn between. two pulleys is lifted as a weft by non-rotatable means 33 and inserted, e.g. in a warp-kniting machine. Insert yarn from cones 1 passes through an eye 4 in an oscillating arm 3 which moves in synchronism with the knitting machine being driven from the main shaft. Arm 4 inserts the yarn round pulleys 8L, 8R on left hand and right hand endless chains 5L, 5R carried on sprockets 6L, 7L and 6R, 7R. Mounted with each pulley 9 is a top 10 with a point and a tab 33 which lifts the thread out of the pulley as it moves round the lower sprocket. To prevent the insert yarn from snarling up at the start and finish, brakes 12L, 12R are provided comprising bars with soft rubber surfaces to engage the pulleys actuated by solenoids interlocked with the start and stop switches of the machine. With a strong insert yarn, the brakes may be applied continuously. The warp threads 26 for knitting are supplied by guides to needles 18 from beams 27. As a pulley reaches a lower sprocket the yarn lifted by tab 33 is engaged by a hook 16L or 16R and the tension is reduced as it is knitted into the fabric. This arrangement inserts a weft in every other course whereas if hooks 16L, 16R are not used the inserts are placed in every course.
