Title: Fish lures
IPC: A01K85/02
Filed: 1972-12-15
Abstract: 1429940 Automatic fish striking N F BIDWELL 12 Dec 1973 [15 Dec 1972] 58036/72 Heading A1A A two part fishing lure comprises a cap attached by at least one line to a body which houses at least one concealed hook which is released upon striking. The cap and body separate upon striking. In one form, Fig. 4 (Prov), the lure comprises a longitudinally slotted body 1 which may be slidable upon line 3. Hook lines are fastened to a correspondingly slotted end cap 7, which is non-slidably secured to the line and have their hooks retained in recessed ramps 5 of the body slots 4 either by friction or resilient bands located in circumferential grooves 6. Upon striking, the cap and body are separated a distance determined by a line stop (not shown) and the hooks ride up the recessed ramps 5. The body 1 need not have an axial bore 2 in which case the longitudinal slots 4 and hook lines extend to the end of the body with the hook lines being connected to a stop behind the body. Alternatively the recessed ramps may communicate with a short axial bore with the hook lines being extended into the bore and again tied to the stop. The body may be formed in sections and the slots and grooves may be twisted to encourage spinning. In the Fig. 8 (comp) form the body comprises top and bottom plates 14, 13 spaced by forward and rear pairs of bottom plate curved projections 15, 16 and 17, 18. One hook lies in each space formed between projections 16, 18 and 15, 17 and one lies around projection 17. Upon striking, the shape of the projections causes the first two hooks to move laterally and the third hook to move upwardly through slot 20. The plates are shaped to cause wobbling.

Title: Hydraulic flow-operated shut-off device
IPC: F15B20/00
Filed: 1970-12-11
Abstract: 1299658 Valves BENDIX CORP 11 Dec 1970 [29 Dec 1969] 59055/70 Heading F2V A valve 36 having surfaces exposed to pressures representative of the flows in the supply and delivery conduits of an hydraulic apparatus is moved against a spring 48 towards a position blocking the supply conduit when the difference between the flows, which may be due to rupture of a pipe-line, exceeds a predetermined amount. The pressures are derived from a throttle 74 in the supply conduit 78 and a throttle 96 in the return conduit 86. The pressure upstream of the throttle 74 is communicated through a restriction 66 and a passage 72 to a space 40 within the valve while that upstream of the throttle 96 is communicated to a space 46 through a passage 86 and a restriction 104, the downstream pressures acting directly on spaces 38 and 42 through passages 78 and 97. A second spring-loaded valve 54 is subjected to the pressure drop across the throttle 74 so that it opens to provide additional flow in parallel with the throttles when pressure fluctuations occur. When a single-acting piston is to be supplied, the throttles 66 and 104 reduce the speed of the valve 36 so that the piston reaches the end of its travel before the valve is closed by the difference in flow to the two sides of the piston.

Title: Geographic addressing by interrogation for controlling airport ground traffic
IPC: G01S13/934
Filed: 1973-12-20
Abstract: 1424900 Radar BENDIX CORP 20 Dec 1973 [22 Dec 1972] 59114/73 Heading H4D A system is described for geographic addressing of an individual portion D, Fig. 1, inside a field of interest 10, which utilizes a transponder system wherein a transponder receiving a first message may be suppressed for a predetermined period of time thereafter, and wherein an unsuppressed transponder responds to a second received message. First means 14 are provided for transmitting the first message over the field of interest except along a first relatively narrow beam 20, and second means 16 are provided for effectively transmitting the second message along a second relatively narrow beam 22. The intersection of the two beams defines the portion D. In application to the location and control of grounded aircraft at an airport the transponders are standard air traffic control transponders installed on the aircraft. The first and second means 14, 16 are air traffic control radar beacon system (ATCRBS) interrogators operating cooperatively. The interrogator 14 first sends a pulse P1<SP>1</SP> on a broad beam, so that it is received by all transponders within the area 10. Then, after 2 micro-seconds, it sends a suppression pulse P2<SP>1</SP> on a similar broad beam but which has a notch corresponding to the narrow beam 20. This suppresses reception by all transponders except those within said beam, for a period of 35  10 microseconds. After a suitable interval during the said suppression period, the interrogator 16 sends a pulse triad P1, P2, P3. The pulse P1 is sent on a broad beam, and the said interval is determined by the consideration that no unsuppressed transponder within the beam 20 must make a false response. The pulse P2 follows after 2 microseconds and is sent on a broad beam which has a notch corresponding to the narrow beam 22. This suppresses reception by all remaining transponders except those within the area D. The pulse P3 is sent 8 microseconds after the pulse P1, and causes a response by any transponder within the area D, giving particulars of the aircraft concerned. As shown in Fig. 3, the interrogator 14 comprises a clock 30, an encoder 32 an interrogating pulse transmitter 34, and an aerial system 40. It also comprises a link transmitter 38 and a directional aerial 40, whereby command pulses Pa, Pb are sent to the interrogator 16. This comprises a receiver 44 for said command pulses, a decoder/ encoder 42 an interrogating pulse transmitter 46, and an aerial system 50. The location of the responding transponder is determinable from the azimuth angles of the aerial systems 36, 50.

Title: An arrangement for the regulation of the power factor of the load current of a synchronous generator
IPC: H02J3/18
Filed: 1968-12-13
Abstract: 1,243,077. Power factor improvement. LICENTIA PATENT - VERWALTUNGS G.m.b.H. 13 Dec., 1968 [14 Dec. 1967] No. 59511/68. Heading H2H. A synchronous generator U G  is operated at a leading power factor substantially equal to unity by compensating the wattless component of the generator output current, this compensation being effected by a group of capacitors C which are switched on and off, with a minimum delay, by anti-parallel connected valves (not shown) preferably of semi-conductor type. Such compensation allows a reduction of the field current and the generator air gap, produces a reduction of the generator short-circuit current and ensures that the generator terminal voltage remains constant over a range of output currents with constant field current. Typical compensating actions and voltage-output current characteristics are discussed, Figs. 1 and 2 (not shown). In the supply network shown, the voltage at the main bus-bar U may be maintained constant by adjustment of the generator field current. The voltage fluctuations at consumer bus-bars U1, U2 can be compensated by capacitor groups C1, C2 switched by antiparallel connected valves in a manner similar to the operation of the capacitor group C. Series capacitors may be employed instead of parallel-connected capacitors. The network may also include compensating inductances switched by anti-parallel connected valves.

Title: Light signal apparatus
IPC: F21K99/00
Filed: 1969-12-09
Abstract: 1292298 Visible signalling-apparatus AGA AB 9 Dec 1969 [24 Jan 1969] 59988/69 Heading G4F A light signal apparatus for visibly indicating a spatial region comprises a light emitter for generating a beam of visible light having a portion of highest intensity, and means for scanning this portion of the beam over a region adjacent to the spatial region and symmetrical thereto. In Fig. 1, LE designates a light emitter comprising a laser light source LS and a beam expander BE producing a nearly parallel light beam B. A level MO, and another at right angles to the one shown, enable the beam B to be adjusted to have its axis A accurately vertical. Scanning means MS comprises a prism DM having a slight inclination to the axis A and an edge which splits the beam B into two beams B<SP>1</SP>, B<SP>11</SP>. The prism DM is held in a support SU rotatable by a motor M about a shaft SH coaxial with the axis A. The spatial region to be indicated is the horizontal plane corresponding to the line R. To the eye of an observer located in this plane a flash of light will appear twice during one revolution whereas, if the eye is in the direction R<SP>1</SP> or R<SP>11</SP>, it will see only one of the beams which will appear once for each revolution. At a point between R and R<SP>11</SP>, the strength of the flash from beam B<SP>11</SP> is stronger than that from beam B<SP>1</SP>. The apparatus can. be modified for indicating a plane of adjustable inclination with the aid of graduated circles and bearings for adjustably supporting the apparatus, thereby enabling adjustment of the inclination of the axis A. If the prism DM is rotated at 20 c/s., the flashes of twice this frequency seen along the line R will appear as continuous light to the eye of the observer. In a modified embodiment for indicating a line (Fig. 2, not shown), the beam is emitted with its axis directed along the line to be indicated and a wedge is placed with its plane of symmetry perpendicular to the axis and rotated about it, whereby the axis of the deflected beam generates a conical surface and an eye placed in the direction of this axis sees one flash for each rotation of the wedge. To an eye placed in the direction of the line to be indicated, however, the light will appear continuous, if the beam is symmetrical about its axis of rotation.
