Title: Sealing ring for sewer pipe connections
IPC: F16L21/02
Filed: 1975-10-02
Abstract: 1466208 Pipe couplings SEMPERIT AG 2 Oct 1975 [4 Oct 1974] 40349/75 Headings F2B and F2G In an elastomeric sealing ring for a spigot and socket pipe coupling, the ring is made more resilient radially by having L-section lip 2, 4 separated at its free end from a supporting lip 5. When high internal pressures are encountered, and the ring is compressed radially, the tip 6 can hook around the lip 5 to prevent it from being displaced. The ring is stated to obviate the need to machine the external diameters of the spigot ends of asbestos cement sewer pipes to size.

Abstract: 995,140. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 15, 1961, No. 40817/61. Drawings to Specification. Heading H3B. [Also in Division H1] In a superconductive, bi-stable, switching device, each crystron comprising a thin film gate conductor and control conductors, it is shown that the time constant L/R is dependent on the penetration depth of the magnetic field produced by the control current, which is itself dependent on the thickness of the film. The optimum value of time constant is obtainable from a family of curves relating time constant and thickness of gate conductor for materials of different restivity. Specifications 862,178 and 941,427 are referred to.

Title: Apparatus for dividing solids
IPC: C13B10/12
Filed: 1963-09-25
Abstract: 1,066,793. Hammer mills. AMERICAN FACTORS ASSOCIATES Ltd. Sept. 25, 1963 [Nov. 14, 1962]. No. 41087/66. Divided out of 1,028,200. Heading B2A. Apparatus for dividing solid material, particularly for breaking sugar-cane into chunks before being fed into fiberizing apparatus disclosed in Specification No. 1,066,792, comprises a rotor 223 carrying pivoted hammers 224 around its periphery, and an anvil having two parts 229 and 230, which surround the rotor, but leave an opening between their upper ends, through which opening material can be fed, e.g. by rotating rollers 236 and 237, into the working space between the rotating rotor and the stationary anvil parts. The lower ends of the anvil parts 229 and 230 are pivotally mounted at 228, on a beam 226 supported by the main frame 220, which beam can be adjusted towards or away from the axle 222 of the rotor, as by screws. The upper ends of the parts 229 and 230 are attached, respectively, to beams 235 and 231 whose ends are pivotally connected, by turnbuckles 233a and 233, to a housing secured to the frame 220. The working space between the rotor and the anvil parts can therefore be adjusted, by turning the turnbuckles and/or moving the beam 226. By removing the pivot pins connecting the turnbuckles to the housing and by swinging down the pivoted housing portions, shown in dotted lines, and then swinging the anvil parts 229 and 230 completely apart (the resulting position of part 230 only, being shown in dotted lines in Fig. 2) cleaning and repair, or replacement, of the hammers is facilitated. Each anvil part comprises a plurality of circumferential ribs 240 Fig. 1, which are separated by divergingly and outwardly tapering openings, and are connected by tie-bars 241. Mounted on, and projecting within, the anvil parts are lugs 242, between which pass the free ends of the rotating hammers 224, thus forcing the resulting broken material, through said openings, into a collecting space under the anvil parts, from which space the broken material may be conveyed to the above-mentioned fiberizing apparatus. One or both of the feed rollers 236 and 237 may be toothed, and one, e.g. roller 237, may be mounted on a movable, spring-backed bearing 238.

Title: Fuel cell and control device therefor
IPC: H01M8/04
Filed: 1975-10-07
Abstract: 1527247 Control of oxidant supply to fuel cell INSTITUT FRANCAIS DU PETROLE 7 Oct 1975 [8 Oct 1974] 41102/75 Heading H1B A fuel cell has inlet and outlet ports connected to an electrolyte feeding circuit including a pump for electrolyte circulation, and inlet and outlet ports for oxidant with valve means for opening and closing these, and control means connected to the valve means and adapted to open and close them in response to flow conditions in the electrolyte circuit; this facilitates start-up and shut down of the cell, in that oxidant can only be supplied when there is electrolyte flow in the cell, thus preventing accidental damage to the electrodes. In one embodiment, the valve means are electrically controlled valves; a pressure sensitive switch downstream of the pump in the electrolyte circuit serves to open the valves when electrolyte is flowing, and close them when it ceases to flow. Alternatively, a generator coupled directly to the motor which drives the electrolyte pump may supply the signal to open and close the valves. In another embodiment, part of the electrolyte flow tube is vertical and transparent, with an opaque ball in the transparent part, and a light source and photo-cell either side thereof, so that when electrolyte flow causes the ball to rise, light reaches the photo-cell thereby generating a signal to open valves in the oxidant line; on stopping the electrolyte flow the ball falls and blocks the light to the photo-cell, thus closing the valves. In Fig. 5, the valve means comprise a valve 31 with seat 32; electrolyte pressure downstream of pump P causes deformation of membrane 37 against the effect of spring 38 to open the valve; on cessation of electrolyte flow spring 38 closes the valve. Fig. 6 (not shown) shows a similar arrangement, but which uses the pressure difference between the upstream and downstream ends of the pump.

The platens 1 of a multi-platen press have guide surfaces 4 which mate with surfaces 3 on columns 2 and the surface lie in planes which are substantially parallel to the diagonals of the platens but displaced from their corners towards the columns. The surfaces there remain in engagement as any platen expands at substantially the same linear rate with respect to both its length and breadth. The surfaces 4 are formed on angle brackets 6 secured to the sides of the platens and the surfaces 3 on angle brackets secured to the columns. Fig. 4 shows an arrangement which resists any tendency of the platens to tilt, the guide surfaces 4a, 4b, formed on brackets secured to the platens, facing opposite ways. In Fig. 1, the angle brackets secured to the columns and having the surfaces 3 also have fixed to them to stop plates 5 on which steps are formed, and the angle brackets 6 carry projections 7 of varying lengths so that, as the platen moves, a step awaits a projection 7 however it expands.

Abstract: 1459280 Remote control; controlling roadtraffic signals MINNESOTA MINING & MFG CO 8 Oct 1974 [9 Oct 1973] 43497/74 Headings G4H and G4Q A pulse train recognition circuit uses a first pulse generator 14 controlling a first switch 18 to check the intervals between pulses, the first switch 18 controlling a second pulse generator 24 to check the duration of the train, a second switch 30 being controlled to produce a recognition output by the second generator 24 and a third 34 itself controlled by the second 24. In Fig. 1, the three pulse generators 14, 24, 34 are inhibited by a pulse at their left inputs shown, there being a delay before the production of the first output pulse following removal of inhibition (i.e. end of input pulse). Normally, the first generator 14 pulses first switch (flipflop) 18 to inhibit second generator 24, third generator 34 pulsing second switch (flip-flop) 30 to ensure no recognition output at 36. When a pulse train is received at 8, the pulses are amplified, integrated and level-detected 10, 12, those energetic enough inhibiting first generator 14 and pulsing first switch 18 to remove the inhibition on second generator 24. If the interval between pulses from 12 is short enough, first generator 14 does not produce any pulses and second generator 24 is kept uninhibited. If this state persists long enough, second generator 24 produces a pulse to second switch 30 to initiate a recognition output pulse at 36, this output pulse being terminated after a delay defined by third generator 34. The generators each use a capacitor (discharged for inhibition) and a unijunction transistor. The gate voltages of the latter in the second and third generators 24, 34 are periodically lowered by a fourth pulse generator 38 to assure low temperature operation. The recognition output can be used to control traffic lights, the pulse train being derived from a modulated light beam from an emergency vehicle. There may be a plurality of the recognition circuits at a road intersection, an input to the second generator 24 of each permitting one to be rendered operative alone.
