Title: Fluid dispensing nozzles
IPC: F16K21/20
Filed: 1970-12-03
Abstract: 1332500 Filling tanks DOVER CORP 3 Dec 1970 [4 Dec 1969] 57527/70 Heading B8T [Also in Division F2] A nozzle for dispensing fuel into a vehicle tank has a valve 15, Fig. 1, for controlling the flow from an inlet 11 to a delivery spout 14, and means for automatically closing the valve when the discharge end of the spout becomes submerged. A handle 53 and valve actuating lever 45 are pivotally connected to one another by rivet 54. Upward movement of the handle 53 from the position shown causes the lever 45 to move with it to open the valve 15. The handle may be retained in the valve-open position by the operator, or by engaging the free end of a spring-biased trigger 67 in one of the flow-rate setting notches of a rack 72. With the valve open, the consequent flow passes through a spring-biased poppet valve 27 and creates thereat a Venturi effect forming a suction which is normally destroyed by air flowing in through opening 37 and along passages 36, 38, 39. However, when the tank is full the opening 37 becomes submerged in the fuel so that the compensating air flow is prevented and a reduced pressure is created in diaphragm chamber 35. Thus diaphragm 32 raises locking rod 41 to unlock plunger 43 and thereby enables valve spring 16 to close the valve 15 by pivoting the lever 45 relatively to handle 53 about rivet 54, the plunger 43 being pulled downwardly against the action of its return spring 44. On completion of the valve closing movement of lever 45, trigger 67 is automatically sprung from engagement with the rack 72 thereby causing the handle 53 to drop and the spring 44 to return the plunger 43, whereafter subsequent removal of the spout from the tank automatically locks the plunger so that the components return to their initial positions as shown. The valve stem 17 is located in a pivotally-mounted bushing (61), Figs. 4 to 6 (not shown), or between a pair of roller-like members (90, 92), Fig. 15 (not shown), carried by the handle. The spout 14 is secured to the nozzle body by a screw 24 which readily breaks to permit detachement of the spout in the vent of it being inadvertently retained in the tank when the vehicle is moved.

Abstract: 1,173,440. Making steel sheets; rolling; altering physical structure. NIPPON KOKAN K.K. 22 Dec., 1966 [22 Dec., 1965], No. 57591/66. Headings B3A, B3M and B3V. Steel sheets are cold-rolled in two stages by utilizing a chart, Fig. 4, showing the desired grain size and strain ratio values which are obtained by the combination of a selected primary and secondary reduction rate, the sheets being annealed prior to and subsequent to the secondary reduction. A low carbon rimmed steel having ultra deep drawing properties, i.e. a high strain ratio r, is formed by a 60% primary and secondary reduction whilst a steel having good shapability is formed by a 75% primary and a 35% secondary reduction, the steel in both cases being annealed prior to and subsequent to the secondary reduction at 700‹ C. for 8 hrs. and at 730‹ C. for 10 hrs. in a decarburizing atmosphere, respectively. A steel having high rigidity is produced by a primary reduction of at least 40% and a secondary reduction of at least 70%, the steel being annealed in a non-decarburizing atmosphere.

Title: Apparatus for detecting the position of a railway track
IPC: G01B21/16
Filed: 1972-12-15
Abstract: 1417160 Classifying railway track position errors FRANZ PLASSER BAHNBAUMASCHINEN-INDUSTRIE GmbH 15 Dec 1972 [24 Dec 1971] 57950/72 Heading H3H A vehicle mounted apparatus for detecting the difference between the desired and the actual position of a railway track determines the maximum difference in the each period between zero differences and classifies the maximum according to magnitude and direction. Preferably the classification comprises incrementing a counter for the relevant range. The actual position is preferably the mean position determined by filtering the actual position signals in a low-pass filter with a constant of about one minute. As described, the difference (which may be height, gauge or versine) is measured by strain gauges 1-4 in a bridge configuration. The bridge output, which is proportional to deflection, is amplified at 5, lowpass filtered at 7 and after amplification at 11 provides the datum. The output of amplifier 5 is also fed to potentiometers 13-15 with their other ends connected to datum and with their sliders set to different positions. An output signal is provided on line 16 when the input exceeds a minimum value; on lines 16 and 17 when the next value is exceeded and on 16, 17 and 18 when a third value is exceeded thus defining 3 bands and a dead band. The signal(s) are applied to Schmidt triggers 19-24, positive signals being gated to 19, 21 and 23 and negative to 20, 22 and 24 by reference to datum 18. A positive signal in band 1 sets bi-stable 29 while a positive signal in bond 2 sets bi-stable 30 and resets bi-stable 29 ensuring that only the bistable corresponding to the highest bond attained is set. When the signal drops into the dead bond, trigger 19 resets, and monostable 25 produces a pulse enabling gates 32-34 and, in this case, sending a pulse to increment positive band 2 counter 39. The output of monostable 25 triggers device 26 which, after a delay, resets all set bi-stables via OR gates 35-37. A similar process occurs with negative deflections, these being counted in counters 50-52. In an alternative embodiment the analogue signal from the strain gauges is sampled every 20 Ás and digitized to a binary number, the first digit of which represents polarity. The values are sorted into ranges, the peak value and change of sign on crossing the datum are detected and the results are fed to counters as before.

Abstract: 1,110,988. Coin-freed apparatus. EDDY MATCH CO. Ltd. 30 Dec., 1966 [30 Dec., 1965], No. 58266/66. Heading G4V. A mechanism for controlling the travel of coins in a coin-freed apparatus and directing them to a coin box or returnng them to a customer includes a normally horizontal bottom plate for receiving the coins, which is tiltable in two directions according to whether the coins are to be accepted or rejected. The bottom plate 13 is provided with pairs of aligned stub projections 23, 24, 25 received in slots 27 in side plates 11. Spring means 36, 37, Fig. 2 (not shown), and 52 engage the stub projections 25 to urge the plate 13 to a horizontal position. A member 40 pivoted at 43 is bent outwardly at 46 and downwardly to provide bifurcated ends 48 attached to armatures 50 of solenoids 41, 42. The member 40 is forked at 44 to engage a stub projection 25. In operation, energization of solenoid 41 pivots the member 40 in a clockwise direction, whereby the plate 13 slides to the left until stub projections 24, 25 enter slots 31, 33 and the plate pivots about stub projections 23. Similarly energization of solenoid 42 slides the plate to the right and then pivots it about stub projections 24. The slots 27 may be replaced by ridges on the inner surfaces of side plates 11. Walls 12 between the side plates direct the coins on to the bottom plate.

Abstract: 1,183,250. Lasers. UNION CARBIDE CORP. 22 Dec., 1967 [29 March, 1967], No. 58299/67. Heading H1C. A continuously tunable laser system comprises a laser 11, 15, 16 having an output spectrum including a frequency continuum, one end of the resonant cavity comprising an element 16 capable of selecting a narrow band of frequencies from the continuum, and the element being adjustable to change the selected frequencies. The active medium 11 is an organic molecular solution, e.g. Rhodamine 6G in alcohol, or a plastics material and the selection element 16 is a prism or diffraction grating, which may be of the acoustic type. The organic laser is pumped by the second harmonic output of a ruby laser 12, 13, 14. The frequency of the radiation which is reflected back into the resonant cavity by grating 16 depends on the angle of incidence A. The zero order reflection of the selected frequency is reflected from a mirror 18 rotated so as to remain parallel to the grating and thus produce an output beam 23 in a fixed direction. Alternatively an output may be obtained by using a partially transparent mirror 15.

Abstract: 1,248,397. Radiography apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. 19 Dec., 1968 [27 Dec., 1967], No. 58629/67. Heading H5R. [Also in Division G1] A pipe-line crawler is caused to stop automatically at a predetermined position along the length of the pipe by means of a radiation source located outside the pipe at said predetermined position and a radiation detector carried by the crawler and energized by said source to cause the operation of braking means. The crawler is in two parts coupled by a universal joint, the front part being the drive means comprising a battery-operated electric motor and being mounted on castor wheels sprung radially outward to the pipe internal walls. The drive means carries behind it the second part shown in Fig. 2. This has a radiation detector 10 and a shield 11 so that the detector is only energized when it is directly beneath source 13. Radial brakes 12, 14 are then caused to stop the vehicle. The application of the crawler is in pipe weld radiography. The second part also carries a radiation source 15 and adjustable shielding 16 so that film wrapped around the outside of the pipe may be exposed to obtain a radiograph of the weld from a junction determined by the position of source 13. The shield is opened automatically, and as well as brake 14 being applied the drive motor is stopped. Automatic timing apparatus may also be provided which is operated on energization of the detector 10 so that after the exposure the shield is automatically closed and the crawler restarted. Extra detectors spaced apart in the direction of motion may be provided so that the crawler stops at a number of close positions and radiographs of the same weld from different positions may be obtained. Additional detectors spaced angularly round the crawler allow provision of different functions from radiography, e.g. reversal of the motor and return to the beginning of the pipe.

Abstract: 1,274,214. Acoustic measurement of fluid flow. GOAL INDUSTRY (PATENTS). Ltd. 12 Dec., 1969 [16 Dec., 1968], No. 59716/68. Heading H4D. In a method orapparatus for measuring acoustically the rate of flow of gas in a pipe by obtaining signals dependent on the phase difference between the outputs of upstream and downstream ultrasonic receivers 10, 11 and (to allow for the velocity of sound in the gas) on the phase difference between the outputs of a receiver 27 in a path perpendicular to the direction of gas flow, the path length of the signal to receiver 27 is altered by a known amount. In the embodiment a reflector 25 is moved a known distance to give the phase difference from receiver 27. The phase differences are given by signal travel time differences. The transducers are directional and magnetostrictive end transmitters 1, 2 are each secured to phosphorbronze balls (8, Fig. 2, not shown) pivoted in the wall of the pipe. Any misalignment of transmitters 1, 2 or receivers 10, 11 is allowed for by adjustment of phase shifters 17. Zero-crossing detectors change the signals to constantamplitude and a gate 20 produces a train of pulses of width dependent on the time during which both of its input signals are positive; the integrated gate output is applied to a voltmeter 23. to afford a direct measure of the requisite phase difference. A binary counter 42 is utilized to obtain a measure of the phase difference of the receiver 27 before and after movement of reflector 25 by actuator 26. Stray waves reflected by the pipe wall are absorbed by rubber. Each of receivers. 10, 11 may be on the same or opposite sides of the pipe as their respective transmitters. The transmitted waves may be pulse modulated, or A.M. or F.M. continuous waves; the carrier frequency is preferably greater than 20 kHz but not so great as to lead to undue attenuation. The invention is particularly used when solid particles are suspended in the gas; if the concentration of the particles is known, e.g. by measuring the attenuation of #-particles as in Specification 1,274,213 (Division G1), the mass particle flow can be determined.

The implant body 9 may be made of a physiologically-inert, hydrophilic material which swells when placed in water, by between 10 and 45 per cent. This material may be a copolymer of glycol monomethacrylate or monoacrylate containing up to 2% wt of glycol dimethacrylate or diacrylate respectively, and up to 3% wt of methacrylic or acrylic acid. The membrane 11 may be of a different material from that of the body 9 and may be reinforced with a textile. The body 9 may be of hydrophobic material with a hydrophilic surface layer. The implant is made from a mould, Fig. 1 (not shown) consisting of a vessel 4 with a detachable base 1 and a lid 8 with a hole therein, a core 3 to define the chamber 10, and wires 5 pushed through the walls of the vessel 4 and touching the core 3 to define the channels 12. Firstly the membrane 2 is made as a hydrogel with textile reinforcement and formed into a cup shape by drying the hydrogel, or by heating the dry gel. Alternatively, the textile alone is shaped as stated and is coated in the subsequent moulding process. The membrane 11 is then placed inside the vessel 4 on the base 1, and the core 3, wires 5 and lid 8 are positioned, Fig. 1 (not shown). The mould is filled with a monomer solution, de-aerated by suction, and polymerization then takes place. The core 3 is subsequently melted or dissolved, and removed from the cavity 10.
