Abstract: 1,000,266. Heating and massage appliances. H. K. BROSS and F. T. JOHMANN. Nov. 12,1962 [Nov. 14, 1961], No. 42683/62. Heading A5R. A massage pad comprises top and bottom sides 1,2 between wich a rigid coil 5 is mounted, said coil defining a bore perpendicular to adjacent portions of the sides, and actuating means 11 e.g. a magnet, movable in the bore to impart a vibratory motion against the sides in response to the passage of alternating current in the coil. The coil 7 is wound on a tubular non-ferrous frame 8 having end flanges. Diaphragms 10 are mounted across the flanges and enclose a cylindrical permanent magnet 11 in the bore of the frame. In response to the passage of alternating current in the coil, the magnet oscillates about an axis perpendicular to its axis, the dimensions of the bore being such that the angle through which the magnet oscillates is less than 180 degrees. Several vibrating units 5 are mounted with thermostatically controlled resistance wire heating elements 3 between layers 1, 2 at least one of which is soft fabric or felt and enclosed in an outer cover 25 having two sides of fabric. The coil may contain two permanent magnets having like poles adjacent one another, the magnets reciprocating in the bore on passage of alternating current through the coil. Alternatively, two coaxial coils are pivoted, the alternating current supplied to one coil being half a wave out of phase with the alternating current supplied to the other coil and an iron core in the bore of the coil frame being reciprocated along the axis of the bore in response to alternating current in the coils.

Title: Improvements in or relating to electronic telephone exchanges
Inventor: MARTIN ALFRED DARGIE
IPC: H04Q11/04
Filed: 1960-12-14
Abstract: 921,379. Automatic exchange systems. ERICSSON TELEPHONES Ltd. Dec. 14, 1961 [Dec. 14, 1960], No. 43057/60. Class 40 (4). Supervisory apparatus is provided in duplicate, and if at any time one supervisory apparatus emits a pulse but not the other, then one supervisory apparatus is disabled so that only the other is operative in conjunction with the rest of the exchange and a routine test is applied to the operative supervisory apparatus. If the routine test shows up a fault then this supervisory apparatus is replaced by the other. As shown, Fig. 1, if supervisory circuit A emits a pulse unmatched by one from B gate 13A opens to set bi-stable circuit 16A which disables circuit A at gate 18A, and also disables gate 13B to prevent subsequent unmatched pulses from B disabling the latter circuit in a similar manner. In normal operation both outputs from A and B are accepted for use via OR gate 12A, 12B. Operation of 16A (or 16B) resets the continuously operating routine tester 20, Fig. 2, to the beginning of its cycle of tests which are then carried out in succession, each successful test causing the tester to step on to its next test. On a failure being detected the tester fails to step within a prescribed time, and a timer 22 causes an alarm to be given and applies a pulse to change over both bi-stable circuits 16A, 16B. This disables the faulty supervisory circuit and substitutes the other as described with reference to Fig. 1. The routiner then resumes its continuously running sequence on the system as then set up. The supervisory equipment may be involved in the setting up and release of calls and also in metering.

Title: Method and apparatus for separating mingled immiscible liquids
IPC: B01D17/02
Filed: 1971-09-20
Abstract: 1372561 Scavenging vessels MARTIN MARIETTA CORP 20 Sept 1971 [21 Sept 1970] 43664/71 Heading B7A [Also in Divisions B1 E1 and F2] Oil is removed from water by passing the water through an oleophilic web comprising a three dimensional structure of thin strands joined together at nodes, which retains the oil, and subsequently lifting the web therefrom. The oil adheres to the strands and nodes, but does not bridge the spaces between them, so that water can flow freely through the web and drains therefrom when the web is lifted from the surface. Up to 15% of the web's void space is occupied by picked-up oil. The web may be 'dewindowed' polyurethane foam with aperture size 0À10-0À15 inches. Alternatively similar structures of polypropylene, nylon or cotton may be used. The oleophilic properties may be enhanced by priming the web with oil. In Fig. 1, an oil slick is picked-up by an endless driven web C mounted on a moving ship, the oil being largely but not wholly squeezed from the web by rollers 20, 22 before its return to the water. Side plates 10, (12) constrain the water to flow through both runs of the web. The underside of the web and drive roller 18 may bear strips of Velcro (Trade Mark) to assist the friction drive. The ship shown may operate within a boom comprising linked blocks of the same material as the web arranged to confine the slick (Fig. 9, not shown).  Fig. 6 (not shown) illustrates another endless web device which is suspended in an oil tanker when discharging ballast water. The web passes round a submerged perforated box from which the water is pumped out, the water entering the box through the moving web which retains the oil. Squeeze rollers or air jets remove the oil from the web. The submerged box and web are enclosed by a cloth screen. Fig. 8 (not shown) illustrates how a sheet of the web material is located across a polluted stream flowing into a body of water. The web is as above but includes sections of closed cell polyurethane, formed therein by injecting and foaming in situ, which give the web buoyancy. A polluted stream could be delivered on to the top of the web alternatively. In either case the web is periodically withdrawn and squeezed to recover the oil.  As well as confining oil slicks (Fig. 9), booms made of the bouyant web material could be located to protect beaches, wildlife sanctuaries or oyster beds.

Filed: 1967-09-26
Abstract: 1,152,032. Recording tracks of particles. GENERAL ELECTRIC CO. 26 Sept., 1967 [20 Oct., 1966], No. 43826/67. Heading G6P. U-235 is detected in a track-etching process by the formation of holes in a resin material by the fission-fragments and subsequently forming a visual image of the hole pattern. In one method a marking fluid is urged through the holes so as to contact a receptor sheet at the opposite side of the etched material. The receptor material may be porous so as to cause the marking fluid to disperse radially, thus forming an enlarged deposit. Alternatively, an indicator dye, such as phenolphthalein is used in place of the porous receptor sheet and a marking fluid reagent is passed through the etched holes. A visual image of the etched holes in a transparent sheet can also be formed by filling the holes with a fluorescing dye.

Abstract: 1473685 Knitting machines EMPISAL KNITMASTER LUXEMBOURG SA 9 Oct 1974 [9 Oct 1973 30 Jan 1974] 43836/74 Heading D1C Needles 16 are selected in a hand-operated flat knitting machine by a pattern wheel 2b, 2c. rotatably mounted on the carriage 1 coaxially with a stationary electromagnet 9, the wheel comprising a symmetrical ring of control levers 6, 66 displaceable into and out of a working position in which they position associated selection elements for selecting the needles, these elements being provided directly on the levers 66 (Fig. 9) or on a separate selector wheel 3 (Fig. 6), the control levers being selectively settable in the working position by energisation of the electromagnet in accordance with the pattern to be knitted. In a first arrangement (Figs. 1 to 5, not shown) levers equivalent to levers 6 of (Fig. 6) are spring urged to their working position in contact with magnet 9 and are selectively held by the magnet while deflecting associated selection levers 14 to working position, non selected control levers being resiliently deflected instead of the selection levers. In Fig. 6 the levers 6 are spring 29 biassed away from the magnet 9 but are brought into contact therewith by a first curved stationary cam 30 while levers selected by the magnet are held by a second such cam 31 during engagement with the levers 14. In Fig. 9 the levers 66 pivot about vertical axes 33 between working and non-working positions respectively defined by stops 35a, 35 on permanent magnetic plates 32 or by ball catches, the magnet 9 holding the inner ends of the levers to pivot them into working position. The selection elements in this case are downwardly projecting fingers at the outer ends of the levers 66. The electromagnet 9 has a pole piece 11a, 28 located in a slit in a non-magnetic cap 17a and the pole piece may have an electrically insulating coating. The pattern wheel may cooperate with more than one selector wheel 3 (e.g. one for each direction of motion of the carriage) in which case a pole piece is provided for association with each selector wheel.

Title: Acoustic delay line memory arrangement
IPC: H03H9/42
Filed: 1971-09-21
Abstract: 1335884 Delay line memory HUGHES AIRCRAFT CO 21 Sept 1971 [20 Oct 1970] 43941/71 Heading G4C The surface of an acoustic structure provides a plurality of parallel data paths each provided with transmit and receive transducers, a recirculation gate and a data source. The paths may be isolated from each other by grooves, dissipative material, or material having a higher acoustic propagation velocity. Alternatively the acoustic medium may be anisotropic, e.g. piezoelectric, providing inherent beam focusing. One path may carry clock pulses. First embodiments.-Each data source contains an oscillator which is gated by new or recirculated data to provide amplitude- or phase-modulated bursts of carrier signals representing binary digits. Each individual path may be made to store a plurality of bit trains by encoding each train on a different carrier frequency, the transducers comprising wide-band sets of interdigitated fingers, and the corresponding data sources having associated individual frequency demodulators and oscillators and a common signal summer which supplies the transmit transducer, Fig. 7 (not shown). Second embodiments.-A pair of acoustic paths is used for each bit train, one of which is shown in Fig. 9. The transmit transducer 407 is interdigitated as shown and is fed by a push-pull input so that for each input bit a code group such as - 1, - 1, - 1, + 1, - 1, - 1, + 1, - 1 or its inverse is injected into the path 401. The receive transducer 411 is similarly constructed and produces the code group autocorrelation function shown at 461 in Fig. 11. The second path of the pair is similar but is arranged to propagate a group - 1, - 1, - 1, + 1, + 1, + 1, - 1, + 1 or its inverse, the receive transducer producing the autocorrelation function 463. The two code groups employed are complementary Golay codes such that the sum of corresponding terms of the autocorrelation functions is zero except for the centre, main lobe term 467. The outputs of the two receiving transducers are therefore summed to give a single pulse representing the input bit. This embodiment may be extended to store two bit trains in each pair of paths, each path being provided with two spaced transmit transducers and two spaced receive transducers, the transducers in one path being constructed for different, non-interfering codes A, C while those in the other path are for different, non-interfering codes B, D where A, B and C, D are complementary Golay codes. In all these embodiments data paths may be provided on both surfaces of the acoustic structure, and variable access time may be obtained by placing receive transducers at different positions along the paths and selecting them according to the desired access time.

Abstract: 1509988 Adaptive echo suppressors COMMUNICATIONS SATELLITE CORP 22 Oct 1976 [23 Oct 1975] 44083/76 Heading H4R In an adaptive echo canceller of the type in which digitized samples of the received signal are stored in an X register and multiplied with a digital representation of the impulse response stored in an H-register to obtain a synthesized echo which is subtracted from the signal in the send path, the magnitude of the impulse response stored in the H- register is monitored and if it exceeds a predetermined value the H-register is cleared and a new impulse response built up in normal fashion. As described an accumulator 12 accumulates the impulse'response samples over the duration of the impulse response, the sum is shifted into a latching circuit 18, compared with a pre-determined value in 20 and if the value is exceeded the H register is cleared. In alternative embodiments the value in adder 14 is monitored and operates a flip/flop (36), Fig. 2 (not shown), when the predetermined value is exceeded, causing operation of a second flip-flop 38 at an appropriate clock time to clear the register, or the number of samples in the register which exceed a predetermined value may be counted and the H register cleared when the count exceeds a predetermined number, Fig. 4 (not shown), or the digital samples can be converted to analogue form, integrated, and compared with a reference, Fig. 3 (not shown). The arrangement clears the H-register when the impulse response is too large, indicating errors due to noise or double talking.
