Abstract: 1, 070, 839. Measuring speed electrically. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 16, 1966 [Nov. 21, 1964], No. 47483/64. Heading G1N. [Also in Division G3] The speed of rotation of a wheel 10 (Fig.2) is monitored by impressing a train of magnetic marks on the surface with a recording head 12 fed from an oscillator 15, picking up the signals with head 13 spaced so that the two pulse trains are exactly 180‹ out of phase at the desired speed, and noting on a phase meter 17 any divergence from this phase difference. Meter 17 comprises a bi-stable multivibrator whose output normally has equal mark-space deviations. Changes from this relationship, indicating a change in speed, produce error signals which are indicated or fed to a speed governor 28 to keep the speed constant. In modifications, the change in frequency or the change in spacing between heads required to bring the phase difference to 180‹ may be measured. The apparatus may be associated with each of two wheels coupled by gears, when phase difference changes indicate irregularities in the gear coupling. The velocity of the driving gear must be kept constant, or the recording pulse frequency maintained linked to this velocity.

Abstract: 1,121,742. Two-part couplings. WESTERN ELECTRIC CO. Inc. 11 Nov., 1965 [17 Dec., 1964], No. 47854/65. Heading H2E. A multicontact connector comprises an insulating body formed from plates 22a-22e, each having a series of spaced grooves extending completely across one surface, the other surface being flat so that when the plates are stacked together they form individual cells into each of which a contact 24 is inserted. The contacts are soldered to the conductors of a cable before being inserted into the body and remain connected together in groups by strips of material forming part of the blank from which they were initially stamped until after they have been inserted into the body when the strips are removed. The connector is used to interconnect colour-coded telephone cables, each cable comprising twenty-five pairs of separately insulated conductors, each conductor of a pair having differently coloured insulation from the other member of the pair, and the two colours together forming a unique combination for that cable. The colours used for the insulation are arranged in two groups, the examples given being white, red, black, yellow and violet for the first group and blue, orange, green, brown, and slate for the second group. The insulation of each pair of conductors has one colour from each group. The plates forming the body of the connector are of different colours corresponding to the colours of the second group, plate 22a being blue, plate 22b orange &c., and alternate cells in each of these plates are occupied by contacts connected to a conductor having the same coloured insulation. The other cells in each plate are occupied by contacts attached to conductors the insulation colours of which are selected from the first group of colours, and the conductors having these colours are arranged in respective vertical columns. For example, Fig. 19 (not shown), all the conductors attached to contacts in column I are coloured violet, in column III, yellow &c. The stack of plates is sandwiched between two outer plates 28, 29 which are differently coloured to correspond to binder tapes round the cable. The contacts each have one long and one short arm, the long arms projecting from the front surface of the connector to engage between the short and long arms of an identical mating connector. The connectors are mated within a plastic band 23 which has keys 50 to ensure correct insertion of the connectors. During transportation, each connector is inserted in a plastic band and a cover, Fig. 16 (not shown), having appropriate key-ways is inserted into the other end to protect the contacts from dust and corrosion.

Title: Method for recovering backwash liquid
IPC: B01D37/00
Filed: 1975-12-02
Abstract: 1520439 Filtering with filter aid ECODYNE CORP 2 Dec 1975 [23 Dec 1974] 49476/75 Heading BID One or more filters using a filter aid layer, particularly of mixed anion and cation resins of 60-400 U.S. mesh, are cleaned using water which is subsequently separated from the filter aid and stored for use in the next cleaning cycle. In the cleaning cycle the water is first passed forwards through the filter to purify the water and then recycled through the filter in the reverse direction to clean the filter. Filters 10, 12 are cleaned alternately so that one is always on service flow, e.g. in the boiler water circuit or treating fuel pool water of a nuclear reactor. Each filter housing contains nylon wound tubular filter elements and service flow is from 14 to 18. When the pressure drop across a filter or the effluent conductivity indicate that the filter aid has clogged with solid impurities or become saturated with dissolved impurities it is taken out of service for cleaning. Tank 50 contains fairly pure water recovered from the last backwashing cycle and this is purified, either by adding resins to tank 50 and pumping the water round circuit 50, 66, 80, 70 or by adding a fresh layer of resin from mixing tank 30 to the filter, on top of the contaminated layer, before pump 80 conveys the water from tank 50 forwards through the filter to tank 48, via valves 86, 24, 28, 56. Valves 86, 56 are closed, make-up water may be added at 64, valves 60, 82, 78 are opened and pump 80 delivers the purified water from tank 48 back through the filter, flushing the resins and water back to tank 50. The backwashing may be accompanied by airscouring. While a fresh filter aid layer is being applied to the clean filter from tank 30, the contaminated water is pumped from tank 50 via valves 98, 104 to settling tank 52. After a settling period, water is pumped via valves 92, 102 from tank 52 to tank 50, leaving the solids to be discharged at 106. If a filter has clogged with solids, then during forward passage of water therethrough from tank 50 to tank 48 a lower flow rate than normal service flow is employed to minimise pressure drop. Typical flow rates are exemplified. Filters may have individual pumps (not shown) to maintain forward flow round a closed circuit, holding filter aid layers in place when the filters are otherwise isolated.
