Abstract: 1,225,600. Mounting outboard motors. E. A. LONGENECKER. 4 March, 1968, No. 55312/70. Divided out of 1,222,681. Heading B7V. [Also in Division E2] An arrangement for preventing the unauthorized use of a clamp adapted to secure an outboard motor 122 to a boat transom 124 consists of clamp screws 120 passing through sleeve nuts 130 and a lock body 146 which when locked by key 148 in a recess 144 of a housing surrounding the nuts locates pivoted levers 134 such that dogs 140 thereof are moved out of engagement with ribs on the periphery of the nuts leaving the nuts free to rotate with the screws 120 and thereby preventing operative actuation of the screws. When the body 146 is unlocked and moved outwardly in the recess 144 the levers 134 move under the action of a spring 138 to engage the dogs 140 with the nuts thereby locking the nuts against rotation and allowing operative actuation of the screws 120. The lock 146 may be completely removable from the recess or movable outwardly only far enough for the dogs to engage the nuts. Anti-friction bearings 133 are provided and also plastics friction plugs 151.

Abstract: 1,234,310. Automatic exchange systems. PLESSEY CO. Ltd. 19 Nov., 1969 [15 March, 1969], No. 13727/69. Heading H4K. In an exchange having a line loop supervision relay and an additional circuit for holding a connection viz. the switch train under the normal control of the line relay, the holding circuit is effective to hold the switch train a even if the loop current falls (but does not cease) below a holding value for the line relay as may happen for example when a subscriber is signalling over the loop for a special service by inserting a resistance in the loop, and b for a predetermined time after the loop is disconnected so that tempery disconnections due to accidental operation of the impulse transmitter or the cradle switch are ignored. With line relay A operative a positive holding signal is supplied at terminal 10 and both transistors T1 and T2 are turned off. If the loop current falls, relay A drops but since some current is still flowing T1 is maintained off. T2 however turns-on to no effect after a time determined by the charging period of capacitor 13. The holding signal is maintained on terminal 10. If the loop is broken, e.g. due to hang-up, T1 becomes conductive due to the now effective positive potential applied over resistor 8. Provided the loop is not remade, T2 turns-on when capacitor 13 becomes fully charged and thereby the holding potential at terminal 10 is removed so that the connection may be released.

[Also in Division H1] A method of bonding a preformed film of a light-sensitive material to a metal layer is characterized by forming a blanket of inert gas, e.g. nitrogen, between the film and the metal layer immediately prior to bonding. In an embodiment, a circuit board blank comprising an insulating layer 1 clad on both faces with copper 2 and provided with holes 3 internally plated with copper 4 is fed between rolls 12. Simultaneously, a resist film comprising a polymethyl-methacrylate film 7 having a protective layer 8 on both sides is drawn from roll 6 and the protective layer 8 on the side of the film to be bonded to the metal is stripped off by roller 9 and the film is then passed over a heated shoe 11 and through the nip of rolls 12. Nitrogen gas is blown into the nip from the holes 14 in a pair of pipes 13 situated on each side of the circuit board blank. The completed laminate is then drawn off and the resist film is selectively exposed to actinic light to cause the exposed and non-exposed portions to become differently soluble. One of these portions of the film is removed to bare the metallic layer which is then removed by etching.

In Fig. 1, the male part A comprises a cylindrical tip 7, which has a  duct 10 with an outlet 11, the duct being connected to the recharging container 50, and an elastic sleeve 8 threaded on to the tip so that it masks the outlet 11, the sleeve resting at one end against an axial shoulder 9 on the top. The female part B includes a junction zone 12 having an orifice 6, the diameter of the orifice being greater than that of the tip 7 and less than that of the outer edge of the sleeve 8. The orifice 6 communicates with the lighter reservoir 51 by means of a passage 2, which is normally sealed by an elastic bush 1. When the two parts are urged together, as in Fig. 2, the elastic sleeve 8 is compressed and seals the joint between the two parts A and B, the tip 7 moving a pusher 5 against the action of the bush 1, so that fuel may flow from the duct 10 into the reservoir 5 by means of the passage 2. In Fig. 6 is shown an alternative embodiment in which the reservoir 59 is opened to the atmosphere during the filling operation. The male part A has a tip 7 with a duct 10 and a sleeve 8 as in the embodiment described above, but in this case the male part A is associated with the lighter reservoir. The tip is mounted slidably in a bore 69, having a hole 70 through which the tip opens into the interior of the reservoir 59 an elastic bush 71 urging the axial shoulder 9 of the tip against a stop 73. A passage 74 is arranged in the bore so that it is normally sealed by the bush 71. When the two parts A and B are urged together, as in Fig. 6, the reservoir 59 is placed open to the atmosphere by means of the passage 74, and fuel runs from the recharging container 58 through passage 11, the duct 10 and into the reservoir 59. Figs 3 and 4 (not shown) show embodiments in which an intermediate chamber is provided between the male and female parts.

Abstract: 1321505 Digital measurement of distance and Speed TOKYO KEIKI KK and NIPPON SEKIYU KK 4 Aug 1971 36588/71 Heading G4H [Also in Division H4] As a navigational aid for a ship 5 docking at or leaving a sea berth 3, the ship's speed and distance relative to at least one submerged sonar transducer 7 on the berth are measured digitally. In the embodiment shown the distances of the bow and stern from two respective directional transducers set back a distance d from the berth edge are measured by respective pulse-echo sonars 9. Each distance is determined by counting clock pulses passed from a generator 26 to a counter 27 through a gate 24 which is (a) opened by each transmission trigger pulse applied to the gate via a delay 25 to compensate for the offset d, and (b) closed by the subsequent ship echo pulse. Offset d ensures that there is no measurement dead zone arising from the finite transmission pulse width. The ship's speed is measured by comparing two successive distance measurements (e.g. made one second apart) in an up-down counter 30. The counts of counters 27 and 30 are fed via memory circuits 28, 31 to indicators comprising an electric display board on the berth, are radioed to the ship, and may be printed out.
