Patent FI-970829-A (FI)
Inventor: THOMAS JOHN HALL
IPC: B65D41/04
Filed: 1997-02-27
Abstract: A package suitable for storing and dispensing potentially dangerous material, which is resistant to opening by children yet readily openable by adults. The package is preferably a bottle which has a body and a finish portion. The finish portion has a threaded outer end for mating with a closure. A resiliently deformable cantilevered beam is connected to the finish portion between the threaded outer end and the body of the bottle. The beam is angled outward and downward from the finish portion. The beam has a substantially vertical locking surface and a pushtab spaced along the beam. The angle of the beam is such that the pushtab may be depressed substantially radially toward the finish portion. The locking surface is located between the finish portion and the pushtab so that depression of the pushtab results in a greater beam deflection and lower deflection force at the pushtab than at the locking surface. A bottle closure has threads for rotatably securing the closure to the finish portion of the bottle. The closure also has a tooth projecting radially inward from its lower inner surface and so shaped and positioned that it will engage the locking surface of the resilient beam whenever there is an attempt to unscrew the closure. It thereby prevents removal of the closure until the pushtab is manually depressed to disengage the closure tooth from the locking surface of the cantilevered beam.

Abstract: 1511122 Fuel injection pumps VYSOKE UCENI TECHNICKE V BRNE 13 Jan 1976 [15 Jan 1975] 01111/76 Heading F1A In a fuel injection pump comprising a piston 1 with a helically edged recess 12 which connects the working space 27 to a combined suction and spill port 21' to end delivery, the consequential fall in pressure in the delivery line 9(91) to an injector causes closure of a delivery valve 4 whereafter the delivery valve Fig. 1 or a relief element 6 Fig. 9 is displaced until the pressures in the working space 27 and the delivery line and acting on the opposed ends thereof are balanced. The speed at which balancing occurs depends on the size of a throttle channel located between the injector and a filling chamber 31 in communication with the port 21' The throttle shown in Fig. 1 is in the form of a channel 51 in a one-way valve 5 but it may instead by constituted by the port 21', or a groove 11 or passages (13, 14), Fig. 4 (not shown) in the piston and connecting the recess 12 to the working space 27. The valve 5 with its throttle channel 51 may be located in the delivery line, Fig. 10 (not shown), or be replaced by a ball-valve (5') and throttle bore through the cylinder end (28), Fig. 3 (not shown). Flow through the discharge valve 4 is via passages 44, 45, 45' and an annular groove 46 or through grooves 48 in the valve periphery, Fig. 11 (not shown). Springs 41, 42 control the opening of the discharge valve 4 and the valve 5, respectively. In Fig. 9 the spring 41 urges the discharge valve 4 to its closed position and also the relief element 6 away from the working space but separate springs may be provided for these functions, Fig. 7 (not shown).

Title: Hybrid network balancing circuits
IPC: H04B1/58
Filed: 1976-01-13
Abstract: 1514055 Hybrid circuits WESTERN ELECTRIC CO Inc 13 Jan 1976 [16 Jan 1975] 1131/76 Heading H4R The impedance characteristics of a 4-part hybrid balancing network 110 are adjusted by respective control signals derived 120 from those parts 1, 3 to which the network and two-way line 210 are connected. The adjustment is made in response to a test signal injected in the transmitter or receiver path before signal transmission and is subsequently held. The network includes a circuit between op-amps (17, 30, Fig. 2, not shown) having overall resistive feedback (R 29 ) and defining a transfer function exhibiting for unloaded cables two fixed real zeros and one fixed and one adjustable pole, and for loaded cables one adustable real zero, a pair each of fixed complex conjugate zeros and poles and one fixed pole. Both circuits have a gain factor. One such circuit (Fig. 3, not shown) consists of two series of op-amp circuits (31, 32) including variable resistors (R 1 , R 2 , R 3 ). The amplitudes of test signals at 211, 212 in Fig. I are compared (Fig. 4, not shown) to produce a gain control signal for R 1  and the phases are compared by Schmitt triggers (50, 51) and flip-flops (52, 53) to produce a frequency response control signal which controls (R 2 ) for unloaded cables and (R,) for loaded cables.

Title: Improvements in and relating to radar ranging systems
Inventor: HUNTER DESMOND
IPC: G01S1/02
Filed: 1953-01-15
Abstract: 744,171. Radar. BRITISH THOMSONHOUSTON CO., Ltd. Jan. 15, 1954 [Jan. 15, 1953], No. 1217/53. Class 40 (7). A ranging device for use in a radar system is provided with coupled # coarse " and #fine " output shafts the angular positions of which jointly represent range and the two shafts are interconnected through a releasable connection which enables the shafts to be coupled only at suitable predetermined relative positions and allows them to be disconnected during rapid manual variation of the " coarse " shaft position and reconnected correctly thereafter. The ranging device may be of the auto-follow type and the manual control used to obtain rapid initial alignment with a desired echo visible for example on a P.P.I. or type A display. In one embodiment the # fine " output shaft 2, which may be coupled to an auto follow arrangement, drives a shaft 8 through an irreversible worm coupling 9, 10. Shaft 8 carries part 6 of a clutch 4 which is normally engaged by spring loaded clutch part 5 on shaft 11. Shaft 11 in turn drives " coarse " output shaft 1 through a reduction gear 13, 14. For manual adjustment handle 12. may be operated to rapidly adjust shaft 1, clutch 4 will slip but will eventually reengage with the serrated surfaces of the two members fully mated. The clutch is designed so that the amount of movement of shaft 1 between two adjacent clutch engagement positions is equivalent to a whole number of shaft 2 rotations. In another embodiment the clutch consists of a disc 12 on shaft 8 having a circle of spaced indentations on it which co-operate with a diametrical spring member 10 on shaft 11  provided with protrusions on its opposite ends. Besides the direct drive through the clutch there is also a connection between shafts 8 and 11 through the gearing shown and differential 27. When shafts 8 and 11 rotate together the inputs to each side of the differential rotate at the same speed but in opposite directions, shaft 32 therefore does not move. In order to alter the positioning of the device pulse generator 38 is controlled to feed a pulse or pulses to one or the other of the solenoid-driven ratchet mechanisms 36 and 37 which operate to step round shaft 32 in one direction or the other. Shaft 32 drives through the differential to cause shaft 11 to move (shaft 8 being held by the worn drive) and each pulse applied to a ratchet mechanism moves the protrusions of clutch unit 10 round until they are opposite the next adjacent indentations.
