Title: Improvements relating to light signalling and like buoys or floating vessels
IPC: B63B22/16
Filed: 1931-03-28
Abstract: In a gas generator forming part of a buoy, the supply of gas-generating solid to the generating chamber is controlled by a valve automatically regulated by the pressure of the generated gas, the regulating means comprising a float working in a U-tube or the like containing a liquid and having one limb in communication with the generating chamber and the other limb in communication with the atmosphere.  As shown, the generating chamber 3 comprises an open-base cylinder extending through the float 1 of the buoy and surmounted by a hopper 9 for the solid, e.g. carbide.  The discharge opening 10 of the hopper 9 is controlled by a valve, the stem 11 of which works in a tubular guard 12 and is attached at its upper end to a lever 17 situated inside the hopper in a ridged part 18 of the hopper cover.  The valve stem 11 is hollow, and has a number of apertures 15 at its upper end.  One end of the lever 17 is pivotally attached to a tube 19, which extends into the float 1 and contains a viscous oil, the tube communicating with the atmosphere through pipes 24. The other end of the lever 17 extends through a slot 20 into another oil tube 21, which is sealed from the atmosphere and is connected at its lower end by pipes 22, 26 to the lower end of the tube 19.  A float 27 in the tube 21 is connected by a rod 29 to the end of the lever 17.  A manual stopping and starting device is provided comprising a spindle 33 carrying a bearing piece 34 and operated by a hand-wheel 35.  In operation, the wheel 35 is screwed upwardly, as shown in broken lines in Fig. 2, whereby the float 27 is set free to rise in the oil in the tube 21; the lever 17 is thus raised, and carbide is supplied to the generating chamber.  As the gas pressure rises, it depresses the oil in the tube 21 through the valve stem 11, apertures 15, and slot 20, the float 27 <PICT:0369011/IV/1> <PICT:0369011/IV/2> sinking and closing the carbide feed valve; as the pressure falls, the float rises and opens the valve.  The gas passes from the generating chamber through a pipe 38 passing up through the hopper and leading through a branch 40 to a fog gun, and through a branch 42 and a purifier 43 to a lamp 44.  The carbide falls down the cylinder 3, in which a number of baffles 48 are arranged, and the sludge finally falls through the bottom of the cylinder, which is tapered so as to prevent the outside water from surging in.  The Provisional Specification refers to Specifications 5615/10 and 13910/12, [both in Class 118 (i), Indicators &c.].

Title: Ultrasonic detection of inclusions in a fluid flowing within a tube
IPC: G01N29/032
Filed: 1973-02-27
Abstract: 1418181 Acoustic detection of inclusions in a fluid; ultrasonic probes E M COLE 27 Feb 1973 9482/73 Headings H4D and H4J The presence of inclusions in a fluid flowing through a flexible tube is detected by deforming at least part of the tube so that it adopts a substantially rectangular cross-section, positioning a pair of supports such that they are urged against respective opposite sides of the tube's cross-section, directing a planar ultrasonic beam transversely through the fluid via one said support, and detecting any change in the ultrasonic signal received by a receiver coupled to the other support. For detecting bubbles in blood passing through a plastics pipe in, e.g. an artificial kidney machine, the pipe is gripped in a probe which houses a CW-energized ultrasonic transmitter and a receiver operated in a throughtransmission mode. The receiver output is AGC-amplified then fed via a filter to a trigger circuit having an adjustable threshold. The trigger circuit responds to any abrupt change in the received signal amplitude and actuates a counter and/or audible alarm. The filter output is recorded and may be analysed to determine bubble size. Other uses of the invention include detecting bubbles in photographic solutions, nuclear reactors, heat exchangers and fuel lines, and checking outgassing operations. Probe details.-As shown the transmitter and receiver 14, 15 each comprise a rectangular piezoelectric slab 16 pre-stressed by sandwiching it between plastics members 17. Blocks 2, 3 support the transmitter and receiver and block 3 has a groove 7 to receive the fluid-carrying pipe 8. The plastics avoids direct transmission of energy to the receiver via the probe material. The pre-stressing clamps the slab 16 vibrations so that these are not significantly affected by pressure pulsations of the fluid. In a modificacation the transmitter and receiver are housed in cavities in the limbs of a C-shaped plastics. member which clips over pipe 8. Magnetostrictive transducers may be used instead of piezoelectric slabs.

Abstract: 558,210. Punching telegraph tapes. TELETYPE CORPORATION. July 10, 1942, No. 9609. Convention date, July 5, 1941. [Class 31 (ii)] Relates to a keyboard perforator, which is especially applicable for perforating telegraph tapes in accordance with a code, and which is of the kind described in Specification 358,737 and comprises a number of punches 29 adapted to perforate a tape 34 by the selective operatior of interponent bars 38 between the punches and electromagnetically operated hammers 37, the bars 38 being controlled by a keyboard mech anism as described in the above Specification wherein keys 15 control permutation bars 28 controlling by links 41 levers 39 connected to the interponent bars 38. According to the invention means are provided to ensure a complete opera tion of the punches when a key is depressed, and to prevent the electrical contacts being prematurely opened, and also to prevent re operation of the key-levers until one operation is complete. Each actuation of a key-lever actuates also a universal bar which oscillates a lever 67 provided with an insulated member 72 adapted to press on an electrical contact 73 adapted to engage a second contact to complete the energizing circuit of the electromagnet 43. Before the circuit is completed a spring-controlled latch member 63 engages a pin 71 on lever 67 and so prevents this lever from moving backwards prematurely. On depression of the armature an anti-chatter device 79 is permitted to move counterclockwise under action of a spring, and a spring arm 83 of this device acts upon the contact 85 to keep the magnet energized by taking control of the contacts 73, 85. The armature also releases a catch or curb member 64 which moves counterclockwise to engage the underside of the projection 71 in order to prevent premature return of the lever 67 after it has been released by raising of the catch 63 by a striker member 75 carried by the armature upon contact of the armature with the poles of magnet 43. The curb member 64 is returned clockwise by a member 77 carried by the armature, and is thus moved to permit a further operation. The tape 34 is advanced by a ratchet 56 engaged by a spring-controlled pawl 55 carried by the hammer 45. The ratchet shaft 56 is provided with pins which engage holes punched in the tape. The punches 29 may pierce the tape so as to leave uncut portions which serve as hinged lids adapted to yield to the sensing pins of a transmitter, as described in Specification 540, 612. To facilitate the back spacing of such tape a tearing-knife 91 by which the tape can be severed when desired is provided with a bevel to cam down the lids when the tape is reversed.
