Submarine core drilling apparatus comprises a base adapted to rest on the marine bed and having a platform 4, vertical guides 6, 7 depending from the platform, and an electric core drill 31 having a plate 33 slidable on the guides. During lowering to the bed the apparatus is supported by a cable 5 attached to pivoted members 21, 22 connected to bolts 26, 27 engaging the platform and a connector 40, the weight of the apparatus causing the bolts to press inwardly to engage a cylinder 30 on the drill to prevent relative movement of the drill. When the base engages the bed the inward pressure of the bolts ceases, and a foot 16 pivots to free a damper piston 34 which is connected by wire 32 to the drill so that the drill sinks gradually into contact with the bed. The apparatus is raised from the bed by pulling the cable 5, the bolts engaging the connector only, the connector raising the drill by means of a cable 41, and the drill engaging a shoulder 45 on the base to raise the base. The ambient water is supplied by a pump 18 to the drill to act as drilling fluid.

Title: Improvements in or connected with the loading of mail bags or other loads on to air-craft
IPC: B64D1/22
Filed: 1924-02-20
Abstract: 234,175. Holt, H. E. S. Feb. 20, 1924. Transferring articles to conveyances in motion. -Apparatus for loading mail bags &c. on to aircraft in flight comprises a hoisting cable 48, Fig. 4, and coupling hook 1 positioned and guided by a bar or rod 2 suspended from the aircraft 3, Fig. 2, the coupling hook 1 being mounted to slide on the rod 2 and operated by hoisting gear 26 on the aircraft, so that, after being engaged by a suspended wire loop 7, Fig. 2, attached to the load 12, the hook can be pulled up with the load. The mail bags 12 are connected by a wire 11<a> to a ball 8 to which the loop 7 is connected through a spring buffer 16. The projector comprises a pivoted platform 10 connected by a spring 15, or a pneumatic cylinder, to a base 9, the platform being held down against the tension of the spring 15 by a catch 14 connected by a rod 19 to a pivoted arm 18 between which and the framework the ball 8 is placed to lock the projector in the set position. A breaking wire 35, Fig. 4, is connected across a loop 36 of the wire 48 so that, should the hook engage an excessive load, the wire 35 will break and allow the hook to slide off the rod 2 and disengage the load. The rod 2 swivels, the upper end being connected by a spring 33 to a bracket 25 attached to the aircraft. The loop 7 attached to the mailbags is stretched between spring-controlled sockets 21 on two poles 13, Fig. 2, and is sighted by means of a disc 22 on one pole 13 and a horizontal netting 20 supported'on poles spaced behind the poles 13. The hook 1 engages and withdraws the loop 7 from the sockets 21, the pull 'on the wire withdrawing the ball 8 to release the projector, which throws the bags 12 forwardly and upwardly. The wire 48 is then wound on the winch 26 until the loop 7 is within reach of a hook 32, Fig. 4, corinected by a wire 31 to a winch 34 worked by the reverse action of the handle 29 by means of which the mail bags are secured. When the hook 1 is out of use the spring 33 is detached from the rod 2, which is then swung up and secured under the fuselage. The mail bags may be encased in a light, cylindrical, metal case and projected by an air tube or a gun into the air or along a track. The light metal case may be protected by an outer case having a spring buffer in the base, the outer case falling to the ground soon after discharge. The loop 7 may be supported on a ship by bow-shaped arms pivoted to a telescopic mast supported on two axes at right-angles, a gyroscope attached to the mast operating relays to close the circuit of electric motors geared to quadrants on the mast, so that the mast is maintained in a vertical position and the loop of the wire at a constant height irrespective of the rolling and pitching of the ship. Specification 199,555 is referred to.

The cap 14 has an open mouth 15 and is formed with inwardly projecting ribs 16. Any attempt to refill the bottle will result in liquid filling the hollow cone 10 and forcing it on to its seat 9, from which it is forcibly removed by the ball 8 when the bottle is inverted.

Abstract: 1,007,074. Automatic frequency control systems; stabilizing transistor oscillators. BENDIX CORPORATION. Feb. 3, 1964 [Feb. 5, 1963], No. 4518/64. Headings H3A and H3T. A crystal oscillator is compensated against frequency drift due to wide temperature variations by a bridge including a plurality of temperature variable resistors 44, 52, 54 whose output is applied to a voltage variable semiconductor capacitor 36 connected in series between the crystal and a D.C. voltage blocking capacitor 38, all being series resonant connected between the collector and base of the oscillator transistor. The crystal may be an A.T. cut producing a rising and falling frequency drift with temperature. This is compensated if, at an initial lower temperature limit at which the whole bridge is balanced, resistor 49 has a low value compared with resistor 46 and this has a value greater than negative temperature coefficient resistor 44 at higher temperatures. Variable resistor 52 then must reduce to the value of resistor 52 at a higher temperature and variable resistor 54 must be less than resistor 52. Capacitor 60 may be omitted. Alternatively the diode 35 may be forwardly biased and its resistance varied to vary the effective value of shunt capacitor 60.

In a railway vehicle a king pin subjected to large braking and traction forces in a longitudinal direction is mounted in a link which is pivoted transversely of the pin to the longitudinally extending arms of bell cranks having their fulcra in the bogie frame and their other arms extending transversely, the pivots and fulcra comprising bearings of rubber or like material permitting angular movement of the work in a transverse vertical plane and angular movement of the arms in longitudinal vertical planes. As shown, a king pin 11 mounted upon a vehicle superstructure, is surrounded by a sleeve 19 fixed in a transverse horizontal link 12 which is pivotally supported at the ends of the longitudinal arms of bell crank levers 13, 14 fulcrumed on bogie transoms. Joints between the links and the bell crank levers comprise each an inner metal member 22 and an outer metal member 23, these members being formed with spheroidal surfaces and being separated by a rubber layer 24 preferably bonded to one of the members. The outer member 23 is split on radial planes into three sectors and must be contracted to pre-compress the rubber 24 on assembly. Similar joints are provided at the fulcra of the bell crank levers 13, 14. The transverse arms of these levers are forked to straddle control springs 17, 18, each spring comprising a rubber sandwich 31 with interleaves 35, which is bonded to metal end plates 32 and precompressed between stops 33 on an anchorage 34.
