Abstract: 1,256,491. Membrane assembly; reverse osmosis. PORTALS Ltd., A. J. TOOTH and J. A. THORP. 9 Dec., 1968 [12 Sept.; 1967], No. 41638/67. Heading B1X. [Also in Division F2]  A semi-permeable membrane assembly for use in reverse osmosis comprises a multi-ply, elongated porous tube constructed from a porous fibrous tape or tapes and having a semipermeable reverse osmosis membrane as an inner or innermost ply. The tape or tapes may be of paper reinforced or made solventresistant with a resinous material, e.g. phenol formaldehyde, melamine formaldehyde, or an epoxwy resin, in an amount of from 2 to 10% or up to 50% by weight of the dry weight of the paper. The membrane may be covered by removable layers of for example calcium alginate or polyethylene oxide and the membrane may be of a modified cellulose acetate. The tube is made by winding the tape or tapes in a spiral tube windup machine. Glass fibre tissue and mats may be incorporated in the tubes, the tissue and mats being impregnated with a heat curable epoxy resin. The membrane may be applied by showing a bob supporting the membrane material through a wound tube. Six examples of multi-ply porous tubes are disclosed. With reference to Fig. 1, the porous tubes 10 are connected in parallel in an apparatus solution to be treated passing into the apparatus at 31 under pressure and the treated solution being withdrawn at 32. In a further construction an assembly of porous tubes may be connected in parallel or series by the use of different end caps (Figs. 2, 3, not shown). The tubes may depend from a sealing plate, the ends of the tubes remote therefrom being sealed by end caps (Figs. 4, 5, not shown).

Abstract: 1,258,521. Ball bearing. NORTH AMERICAN ROCKWELL CORP. 8 Aug., 1969 [3 Sept., 1968], No. 39888/69. Heading F2A. In an angular contact ball bearing at least one of the races is supported around two axially spaced annular bands on the side of the race opposite the raceway. The annular space 18 defined by the bands and the race is smaller in area in axial cross-section than the area of the race which lies between the two bands so that the race may deflect under load as an endsupported beam between the annular bands to reduce axial and radial stresses when the bearing is operating under load. Both races of the bearing may be provided with an annular relief to provide for deflection. Two such angular contact bearings may be provided with a spacer 53 between a pair of races so that the bearings are preloaded.

Abstract: 1,264,323. Measuring displacement. GEORGE RICHARDS & CO. Ltd. 18 March, 1969 [18 March, 1968], No. 12925/68. Heading G4H. The phase displaced signal 13 derived from a reading head 11, pulsed by four phase displaced reference signals and sensing a grating 12, is used to sample hold circuits 28, 29 so that the count in decade counters 26, 27 receiving clock pulses from a source 22 is displayed on number tubes 18, 19. To ensure that the count is not read out during a clock-pulse a bi-stable 32 setby the phase displaced signal 13 is reset by a clock pulse, the trailing edge of the resulting pulse from a trigger 31 which occurs 1“ clock pulses later causing sampling. The counters are reset by a reference signal 35 the phase of which is adjustable by moving the wiper of a zero setting potentiometer 34. The count then represents the fine position of the head relative to a selected datum. To determine the coarse position the signals 13 are counted in decade counters 41, 42, 43, 44, the reference signal 35 being fed to counters 46, 47, 48, 49 the count in which is displayed on tubes 14, 15, 16, 17 for each full count in counter 41-44. To speed up the display frequency, pulses from clock 22 may be fed into decades 42 and 47 provided the count in decades 43 and 44 is not "9" (that is provided a read-out pulse is not imminent), when, by coupling the "8" and "1" outputs of the decades 43, 44 via gate 71 to gate 67, clock pulses are inhibited. Clock pulses are also inhibited when a carry signal from decade 41 or 46 is imminent. If a sampling signal arrives simultaneously with a reference signal 35 a false reading may be given. To prevent this a sampling pulse generator 75 may deliver pulses of less than a “ or greater than 1¥ clock pulses, the length being selected by the most significant bit of the fine count (that is the count in decade 27). If it is 8 or 9 a signal on line 76 results in a short pulse being generated to ensure that the counter is sampled before the next clock pulse. The coarse count may be reset to zero by a pushbutton.

Abstract: 1296110 Oscillator circuits; exchange metering PLESSEY CO Ltd 16 Dec 1970 59721/70 Headings H3T and H4K A circuit for generating simultaneously a plurality of different-frequency metering pulse trains for a telecommunication system comprises a plurality of electronic pulse generators differing only in the setting of the frequency determining means and respective switching means controlled thereby. As shown, each generator may be constructed as a plug-in unit and comprises an oscillator TR1, TR2, a pulse width determining circuit C2, TR3 and an output amplifier controlling a plug-in relay IR. Frequency dividers may also be provided. The oscillator is of the cross-coupled complementary transistor type. When the transistors TR1 and TR2 are conducting, capacitor Cl charges through one or more of the timing resistors VR-R3 from a 25 V. supply provided by Zener diode Z1, until transistor TR1 and thus TR2 are thereby cut off. Charging current thereafter flows in the opposite direction until the capacitor voltage is such that the transistors are rendered conducting again. Zener diodes Z2 and Z3 limit the collector voltage swing to - 20 V. and - 30 V. In the pulse length determining circuit, when TR2 becomes conductive TR3 is thereby cutoff and remains so until capacitor C2 is recharged.

Abstract: 1297658 Magnetic brakes; track brakes KNORR-BREMSE GmbH 4 Dec 1970 [4 Dec 1969]. 57829/70 Heading F2E [Also in Division H2] A magnetic brake for a rail vehicle includes a coil for exciting first and second magnet structures 4 which structures 4 act with the rail to produce a braking effect by friction or by eddy current action and are arranged one after the other in a direction along the rail when the brake is mounted on the vehicle, the two structures 4 having respective portions 6, 7 which engage with one another to prevent tilting of the structures 4 during braking. In the embodiment of Fig. 1 the two structures 4 (these being merely representative of a number of identical structures arranged in line) are of U- shape in cross-section and have limbs 5 which engage over an oval coil box 1; the structures 4 are separated by one of a number of partitions 3 arranged in an opening 2 of the coil box 1. Each limb 5 of the magnet structures 4 has a bearing surface 6 which bears on an end portion 7 of the adjacent magnet structure 4. This arrangement prevents the structures 4 from tilting during braking but allows the end faces 8 of the structures 4 to bear fully on a rail surface 9 to effect braking. In Fig. 2 is illustrated a U-shaped magnet structure 10 comprising limbs 11 and 12 juxtaposed to individual limbs 13, 14 of further magnet structures. Triangular pole shoes 15, 16, 15<SP>1</SP>, 16<SP>1</SP> are welded to the limbs 11, 12, 13, 14 and elongate members 17, 18, 17<SP>1</SP>, 18<SP>1</SP> made of non-magnetic material are welded to an edge of the pole shoes. Each limb 11, 12, 13, 14 is provided with a bearing surface 19 for a projecting end portion of an elongate member 17 or 18 at a pole shoe on the other limb of the magnet structure. The bearing surfaces 19 of the magnet structure 10 respectively co-operate with bearing portions of adjacent pole shoes 151, 16<SP>1</SP>. The bearing surfaces 19 are reduced in size by bevelled surfaces 20, 21. The pole shoes are shown as triangular but they could alternatively be rectangular with the elongate non-magnetic members angled to enable them to be welded along two rectangle edges of the pole shoe. The embodiment of Fig. 2 utilizes eddy current effects for braking as does the embodiment of Fig. 3. In Fig. 3 the two limbs 26, 27 of a U-shaped magnet structure 25 are screwed to one another in the web portion and these limbs 26, 27 are inserted in the oval opening of a coil box. The end portions of the limbs have welded thereto by weld seams, e.g. 35, pole shoes 28, 29 to which are welded by weld seams 37, 38 elongate members 33 made of a non-magnetic material with frictional surfaces. The pole shoes 28, 29 project laterally beyond the limbs 26, 27 and bearing portions of the pole shoes lie on narrowed portions 30 of the end faces of respective neighbouring limbs of the same polarity and act to prevent tilting of the structures. Flat support elements 34 which provide additional bearing surface area adjoining the narrowed portions 30 are welded laterally on to limbs 26, 27.

A passage 8, which connects the chambers 2, 4 is closable at its ends by pressure-sensitive diaphragms 5, 5'. Restrictive orifices 12, 12' connect the chambers 2, 4 separately to the atmosphere. A control unit, in conjunction with magnetic valves and a time switch, controls the application of a vacuum to the outlet 9; the switch opening, with a delay therebetween, the ends of the passage 8. This opening of the passage 8 evacuates the milking cups thereby allowing attachment to the teats. When a predetermined quantity of milk has been collected, the ends of the passage 8 are closed by the control unit. Air, entering at orifices 12, 12', then causes the cups to drop from the teats, to be caught by a milking gear holder. A pressure transducer ensures that the milking cups are ventilated before the milking gear is automatically swung out of position. A time relay switches the plant off if the milking gear is not re-applied within a prescribed period in the event of, for example, milking cups accidentally dropping from the teats.
