Title: Speed Stabilizing Brake for Winches
IPC: F16D59/00
Filed: 1967-12-18
Abstract: 1,188,319. Winch drum brakes. JEAN POMAGALSKI S.A. 18 Dec., 1967 [28 Dec., 1966; 12 May, 1967], No. 57310/67. Heading B8B. [Also in Division F2] In a speed stabilizing brake for winches which lower a load by gravity, the difference in speed between a disc 1 (Fig. 1) attached to the winch drum-shaft and a disc 16 coupled to a hand control wheel or crank, is sensed by a feeler and cam arrangement which controls the application force of an internal shoe-drum brake. The feelers are wheels 7 at the ends of a pair of levers 2, 3 fixed on splined shafts 4, 5 which are rotatably mounted on and carried by the disc 1. The disc 1 together with the feeler levers and brake shoes 20, 21 is rotatable within a brake drum 10 which is fixed to the winch frame. The feeler wheels 7 engage interior cam surfaces on semi-circular rings 8, 9 which are attached by pins 12-15 to the disc 16 and are rotatable therewith. In operation, the disc 16 is rotated manually and the position of the feeler wheels 7 on the cam surface is determined by the speed difference between the discs 1 and 16 and hence between the feeler levers and cam rings. If disc 1 gains on disc 16 and given that the halfrings each increase in thickness in the direction of arrow F which is also the direction of rotation of the discs 1 and 16, the cam surface will cause the levers to rotate with their shafts in a direction Fl. Cams 18, 19 on the shafts ends will therefore increase the separation of brake shoes 20, 21 to apply the shoes to the drum 10, the amount of separation and braking force depending on the difference in speed. The cam surfaces' profiles are such that the wheels 7 cannot rotate the half-rings and thus disc 16 relative to drum 10. In an alternative embodiment (Figs. 2 and 3, not shown), the hand wheel, the disc 16 and the half-rings are rotated by torque exerted on them by the feelers. By braking or accelerating manually the speed of the hand wheel, the speed of descent of the load can be varied. In addition, there is provided a locking device in the form of a hand lever whereby the disc 16 can be braked to stop the lowering of the load.

Abstract: 1,153,880. Boring earth &c. B. PERI. 23 Dec., 1966 [29 April, 1966], No. 57631/66. Heading E1F. In a floating drilling rig, the drill string is raised and lowered by reciprocation of a gripping device 2 movable below or in the vicinity of the centre of gravity, and power means to apply an extracting force to device 2. Thus, the tower 8 can be of light contruction since it has to support only one stand of pipe when disconnected from the string. The gripping device may comprise wedges moved to grip or release the pipe by hydraulic jacks, and be raised or lowered by motor 3 via cables 3. the string being held by a gripping device 7 during the return stroke of device 2. Device 7 may be a fixed clamp or alternatively may be similar to device 2 to allow rotation of the string whilst gripped. In other arrangements, device 2 is moved by hydraulic rams or a buoyancy chamber.

Title: Safety system for a vehicle having a seat belt
IPC: B60R22/48
Filed: 1972-12-14
Abstract: 1404357 Vehicle safety system ALLIED CHEMICAL CORP 14 Dec 1972 [15 Dec 1971 22 May 1972] 57774/72 Heading B7H A vehicle safety system includes a seat switch 34 which provides an output when the seat is occupied and a second switch for association with a seat belt to provide an output depending on whether the belt is in position to restrain an occupant, and disabling means for preventing operation of the vehicle starter motor until the outputs indicate that the seat has first been occupied and then the belt has been positioned to restrain the seated occupant. The positive terminal of battery 10 is connected to ignition switch 12, starter switch 14, and gear selector switch 16 which is only open when a forward gear is engaged, but is closed in neutral, park, or reverse. A safety switch 18, open when the seat belts are not engaged, supplies power to a starter coil 20 associated with the vehicle starter when switches 12, 14 and 16 are closed. An activator circuit 22 energizes a display 24 having a buzzer to warn the vehicle driver that the seat belt is not properly fastened. An emergency switch 26 allows a single start without completing the required belt fastening sequence and supplies power to a stall circuit 28 which senses through a vacuum switch 30 whether the engine is running. The stall circuit 28 allows restarting after stalling without the belt being correctly fastened, since the vacuum switch remains closed for a time after the engine has stopped. The circuit 28 is connected to one or more seat units 32 each including a seat sensor switch 34 closed by the presence of a seat occupant and a jostle circuit 36 which inhibits an output if the switch 34 is only momentarily closed. The circuit 36 supplies a normally open switch 38, associated with the seat belt retractor, and a second switch 40 opened when the belt is drawn from the retractor. When either switch 38 or 40 is closed and the switches 26 or 28 have not been actuated the safety switch 18 is open, thus inhibiting the starter coil, but energizing display means 24. Normal starting can only occur if the seat is not occupied or if the occupant sits on the seat while the belt is fully retracted and is subsequently extended.

The acid entering the tunnel 27 is thus preconcentrated while the gases carrying volatile components from the dilute liquid pass to washing section 5 where the gases are washed with cold water and the product is fed outside for re-use. The preconcentrated sulphuric acid flows down the cascades in tunnel 27 and is heated and concentrated by radiant heat from burners 34. The individual cascade trays 29 can be heated to different temperatures by varying combustible mixture to the burners and to leave the last tray at the boiling point of sulphuric acid. A sheet of heat-resistant gas-impermeable transparent silica is placed between the cascades and the burners (Fig. 2 not shown) to protect the burners against leaks of gas and acid.

Title: Eddy current defect detectors
IPC: G01N27/90
Filed: 1971-12-30
Abstract: 1338460 Eddy current flaw detectors NIPPON KOKAN K K 30 Dec 1971 60635/71 Heading G1N In an eddy current flaw detector of the type in which defects in a sample being tested cause variations in the impedance of a coil energized from an oscillator 1 and connected in a bridge circuit 3, the bridge output is, after frequency doubling, synchronously rectified using as a reference signal the oscillator output phase shifted and frequency doubled. An iron pipe being tested is passed successively through two coils arranged in adjacent arms of a bridge, Fig.2 (not shown) which in the absence of a flaw remains balanced. Flaws cause either one or both coils to vary their impedance and unbalance the bridge, the phase angle of the output being dependent upon the flaw. The bridge output is first full wave rectified at 10, Fig. 3 (not shown) and then passed to a band pass filter 11 tuned to twice the oscillator frequency whereby the bridge output is frequency doubled. The oscillator is also fed to phase shifter 19, Fig.4 (not shown) which shifts the phase by an amount equal to the degree of phase shift introduced into the bridge output by a defect of magnitude rendering the pipe defective. After phase shifting the oscillator signal is frequency doubled by fullwave rectifier 20 and band pass filter 24 and applied to synchronous rectifier 18. The output of rectifier 18 is proportional to the cosine of the phase difference between its two input signals and indicative of the flaw in the pipe. Band pass filter 24 may be replaced by a Schmitt trigger.

Abstract: The invention relates to a cover for a refractory containment such as a soaking pit, such a cover comprising a supporting structural framework of beams and cross members (12-15) mounting a refractory mass by means of keying blocks (17). In order to avoid the problems of damage to the main structural frame members at the edges of the cover by striking against billets or billet grabs or by impingement of hot gases, where leakage occurs at the edge seal (19), the refractory mass is so dimensioned as to extend beyond the periphery of the structural framework. A secondary framework (18, 21, 22) is located along at least part of the periphery of the cover and is displaceably mounted on the structural framework such that when a billet or billet grab strikes the secondary framework, which defines the outermost edge of the cover, this can be displaced to avoid serious damage. <IMAGE>
