Abstract: 1406615 Absorbent pads F L WILLING- TON 15 March 1973 [15 Dec 1971] 58234/71 Heading A5R An absorbent pad, e.g. a sanitary pad, an incontinence pad, a bed pad, or a diaper, comprises an absorbent filling enclosed in a permeable wrapper, and is charcaterised in that a gelling agent, intended to gel the body fluids, is impregnated in the filling and concentrated in a part of the pad not extending over its full plan area. The pad is intended to be used with the area having the higher concentration off gelling agent arranged to receive the main flow of body fluid. The concentration of the gelling agent in the small higher-concentration area is preferably at least 20% by weight. The remaining area of the pad may be without gelling agent or may have a lower concentration of gelling agent. The gelling agent may be a cellulose ether; the absorbent filling may be flocked wood pulp; the wrapper may be of permeable fabric or of porous paper incorporating a thermoplastic material. The incontence pad 1 shown is of foldable form and is formed by two individual pads joined by a transverse seam 8. The wrapper 3 has sealed end portions 6, 7 providing hand-holds. The filling 2 is impregnated with gelling agent in central areas 5. The wrapper is sealed longitudinally by a longitudinal seam (4), Fig 2 (not shown). The incontence pad 1 is is intended to be used with a pair of pouched incontinence pants. The incontinence pad may have one side formed of impermealble material. A method of making foldable incontence pads 1 is disclosed, wherein the filling material and gelling agent are deposited on a continuous web of wrapper material, and after sealing the wrapper to provide the longitudinal seam and transverse seams, the web is secured at alternate transverse seams.

Title: Fm demodulator circuit
IPC: H03D3/24
Filed: 1973-12-20
Abstract: 1451385 FM demodulators; a stable multivibrators SONY CORP 20 Dec 1973 [21 Dec 1972] 59221/73 Headings H3A and H3T An FM demodulator comprises an emitter coupled multivibrator 1, 2 having a timing capacitor 3, and a differential amplifier 6, 7 having output electrodes connected to the emitter electrodes of 1, 2 wherein the output e 0  at 31 is proportional to the phase difference between an FM signal applied to the amplifier 6, 7 and the output of multivibrator 1, 2 and also related linearly to the frequency of the FM signal. In operation, initially a current flows via the collector emitter paths of transistors 1, 6 which are then conducting and transistors 7, 2 are in the off state. Subsequently, transistor 6 is turned off and transistor 7 is turned on by the FM input and a charging current flows from the collector emitter path of transistor 1 via the capacitor 3 and the collector emitter path of transistor 7. The charging is completed when the emitter potential of transistor 2 falls sufficiently low as to render transistor 2 conducting and to turn transistor 1 off. Subsequently, the conducting states of transistors 6, 7 are switched over by the FM input and a charging current flows through capacitor 3 in the opposite direction via transistors 2, 6 until the conduction states of transistors 1, 2 are reverted. Transistors 28, 29 prevent saturation and enable a higher operating frequency range. Transistors 20, 21, 24 and associated resistors 22-27 form a temperature compensating arrangement. The demodulated output may be obtained using a multiplier 30 (as shown) or a bidirectional rectifier and a low-pass filter arrangement (Fig. 1 not shown).

Title: Automatic selector for a peripheral unit capable of selectively exchanging data with one or other of two computers
IPC: G06F13/40
Filed: 1973-12-28
Abstract: 1413923 I/O switching circuits COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 28 Dec 1973 [28 Dec 1972] 60080/73 Heading G4A A peripheral device P can be selectively connected to either of two computers A, B, for the exchange of data, by the circuit shown which provides an interlock preventing simultaneous connections to both computers. Assuming computer A to be the first to produce an address pulse FA, bi-stable 2 is set and if a subsequent, overlapping pulse FB occurs to block gate 12 remains blocked. The output GA of gate 11 is passed by gates 21, 25 to produce a selection signal SA to gate the state of the peripheral "ready" signal PR to computer A. Provided the peripheral is in the "ready" state (PR = 1) when GA occurs, a bi-stable 3 is set to prevent a selection signal SB being produced by a further FB pulse and SA is maintained via gate 23. Exchange of data is effected between the peripheral P and computer A when the latter supplies a second FA pulse, and PR is dropped to 0.

Title: Method of collecting seismic data of strata underlying bodies of water
Inventor: TILLEY AUBRA E
IPC: G01V1/38
Filed: 1969-12-30
Abstract: 1285769 Seismic exploration CHEVRON RESEARCH CO 30 Dec 1969 [30 Dec 1968 1 Dec 1969] 63387/69 Heading H4D In a marine seismic exploration method for collecting seismic data suitable for processing to enhance the signal-to-noise ratio, a linear hydrophone array with interhydrophone spacing X is towed by a recording boat at a steady speed V along a survey line, a seismic source is moved at a steady speed V<SP>1</SP> by a shooting boat along a course making an angle α with the survey line and is fired at time intervals T, the resulting hydrophone outputs are individually recorded as traces, and the speeds and courses of the boats are controlled such that the centre points, each located halfway between the source point and hydrophone position (at the recording instant) of a respective source point-hydrophone pair, form a two-dimensional grid including sets of centre points aligned perpendicularly to the survey line. As shown in Figs. 1, 2, 3, a recording boat 12 tows hydrophone array 13 along survey line 11 and is flanked by shooting boats 22, 23 carrying seismic sources 26, 27 and moving along in-phase zig-zag courses 24, 25 respectively. To maintain the flanking position, V<SP>1</SP> cos α = V. A source is fired at points A, B, E, F, G, H in turn on outward legs of the courses to define centre points C1-C24 for source-point A, centre points C25-C48 for source-point B and so on. In this example the between-firing movement components of the source in the direction of and perpendicular to the survey line are about equal (α=26¢ degrees) and equal to 2X, since T is made 2X/V. Since the different centre-points forming a set aligned perpendicular to the survey line are associated with common depth points but different source/ hydrophone offsets, their associated traces can be processed by applying normal moveout and static corrections and composited to suppress random noise and multiple reflections. In addition the traces may be "beam-steered" by applying differential time shifts to them to produce displayed sets of directional traces indicative of seismic energy received from particular directions. This enables both in-line and cross dip components of subsurface formations to be determined. The headings and velocities of the boats may be programmed and controlled automatically by a system including Doppler sonar, radar transponder and gyrocompass navigational aids on the boats (details given). In modifications the two shooting boats may zigzag behind the recording boat, the two zig-zag courses may be in anti-phase, or a single shooting boat zig-zagging behind the recording boat may be used.
