Animated display diagrams are produced by means of a first parallel line grating carried on a blind 27 and at least one further parallel line grating carried on a slide 24, the first grating being movable with respect to the second grating, a lamp 22 and condenser system 23 causing the superimposed pattern of the gratings to be projected through a lens 25 on to a screen 26. The lines in the first grating may be parallel to those in the second grating but have a different spacing, Fig. 1 (not shown), or they may be inclined to, and have the same spacing as those in the second grating. In this way fringes, e.g. MoirÚ fringes, are created. The blind 27 is moved continuously; alternatively, one grating may be oscillated. Gratings of different colours may be used. One grating may be formed as a road intersection. Fig. 3 (not shown) having traffic flow paths. When a uniform grating is moved over this grating, the fringes move in different directions.

Abstract: 1,171,785. Covering cores. AMERICAN AIR FILTER CO. Inc. 22 Nov., 1966 [23 Nov., 1965], No. 52309/66. Heading B8G. [Also in Division D1] An expanded mat is made by depositing filaments on a rotating collector to form at least two filament portions comprising filaments deposited at different angles of lay to filaments deposited in another portion, applying a binder to the mat, removing the mat from the collector, stretching the mat in a direction transverse to the general direction and lay of the filaments, compressing one of the portions of the mat and retaining the compressed portion in compressed condition. The angle of lay of filaments in one portion of the mat can be 5 to 40% greatet than the angle of lay in another portion when the filaments are being collected. The angle of lay of the filaments, e.g. glass, can be varied by altering the velocity of traverse of the filaments along the rotating collector. The binder can be softened, e.g. with water, during stretching of the mat. The solvent can be dispersed on to the surface of the mat from a perforated elongated sack (23) extending transversely of the mat. The flow of solvent from the mat is controlled by the pressure of solvent in the mat, as by an inlet valve (25), (see Fig. 4, not shown). The mat can be oompressed endless belts. The binder can be hardened by heating whilst the mat is compressed.

Surgical pads, tampons or dental rolls are made of cotton fibres in which is dispersed an alkyl carboxycellulose, or an alkali metal salt thereof, which is modified to a more absorbent form by agglomeration-inhibiting means. Sodium carboxy methyl cellulose treated with citric acid, tartaric acid, polyethylene glycol or polyethylene oxide is formed as granules and distributed between cotton layers of the tampon. Alternatively, sodium carboxy methyl cellulose treated with methyl cellulose, or glycerine is made into a film .001-.002 ins. thick and weighing 20-31 mg./sq. in. and the film is laid between cotton fibres layers of a tampon. The tampon is then compressed. The strength, flexibility, stability and rewettability of the film may be improved by adding starch, karaya gum or synthetic alginates or surfactant sodium lauryl sulphate. The film may be of herringbone shape or corrugated. Alternatively, the water-soluble sodium carboxy methyl cellulose may be chemically or physically bonded to cotton threads incorporated in the tampon.

Title: Solid state timepiece with liquid crystal display
IPC: G04G9/00
Filed: 1971-11-18
Abstract: 1358707 Converting HAMILTON WATCH CO 18 Nov 1971 [12 March 1971] 53671/71 Heading H2F [Also in Division G3] In a battery powered wholly electronic watch having a liquid crystal (e.g. p-azoxyanisole) time indicating display which is activated only when an "interrogate" or "demand" switch is operated, there is provided an arrangement whereby the electric field applied to the crystal, is periodically reversed, which is said to prolong the effective life of the crystal. The watch comprises a conventional crystal controlled oscillator time base and a frequency divider chain coupled via a digital time computer to the display. The time base and f divider may be energized continuously from a low voltage (1¢V) silver oxide cell while the display is energized only on demand from a separate high voltage battery. The display may be a 7-bar segment type or a matrix of dots. In Fig. 6, a polarity reversing signal at between 10Hz and 500Hz is taken from an intermediate stage in the frequency divider 30 and is applied via a switch 76A to a transistor 107. The output of Tr107 controls a high voltage flip-flop 81 for applying H.V. to the display segments, e.g. 38, 40 when a respective transistor 91, 93, 911, 931 is rendered conductive by a timing signal at 82, 84 respectively, from an M.O.S. circuit display actuator 34. Thus when for example segment 38 is to be activated either transistor 91 or 93 will be turned ON (by a signal at 82) depending upon the polarity of the outputs Q and Q of the flip-flop 81, whereby to pass current in one direction or opposite direction through the liquid crystal segment 38. The display (Fig. 4) comprises transparent front and rear plates 52, 54 respectively, e.g. of glass separated by spacers (not shown) and sandwiching liquid crystal material 56. The rear surface of the front glass and the front surface of the rear glass are coated with transparent electrode material 58<SP>1</SP>, 58. The coating 58 is etched, e.g. at 61 to define electrodes 60, 61 for each element of 7-bar segments and colon dots. A reflective layer 66, e.g. aluminium film, is formed on the rear surface of plate 54.

Abstract: 1322857 Protective arrangements MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 Nov 1971 [25 Jan 1971] 54285/71 Heading H2K [Also in Division H5] Radiation leakage detector antenna 42T, 42L, 42B, 42R of a micro-wave oven (c.f. Division H5) are electrically joined at their ends 68 to form a series antenna and connected at end 72 to a warning circuit 88 via a special rectifying diode 82 and inductor 86. The warning circuit comprises a potential divider 90 and a gate 92, normally non-conductive with respect to the alarm relay 96. A capacitor 74 prevents D.C. leakage to earth but allows a short-circuit path for currents generated by the microwave frequencies. When the magnitude of this current, after rectification, reaches a predetermined level, gate 92 closes and the contacts 98 are made, energizing a warning lamp 100 or initiating the deactivation of the micro-wave generator. Alternatively the antenna may be electrically separate Fig. 6 (not shown), each operating its own circuit. An absorber load, e.g. a ferrite 104, Fig. 5, may be included in front of the diode. The metal channel carrying the antenna forms the earth side of the transmission line.

Abstract: 1,140,769. Extrusion dies. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ. 6 Dec., 1966, No. 54474/66. Heading B5A. An extrusion die intended for the production of foamed synthetic resin is sectionalized and has an outlet comprising slits 14 in each section 10, 11 and a transverse slit 13 along the mating line 12 of the sections. The slit arrangement is such that no foaming occurs before emergence of the material from the die and on emergence the material bonds together to form an integral extrudate. Typical dimensions are:-width of slits 0À5mm.; distance between slits 14, 1mm.; land length of slits 10mm. The slits near the ends of slit 13 may be somewhat wider than those positioned centrally. Various slit configurations are described, which include sections (15, 16), Fig. 2 (not shown), having interfitting teeth to form slits (18, 19), sections (20, 21), Fig. 3 (not shown), having interfitting teeth to form a honeycomb arrangement of slits (22, 23, 24), diverging slits (25), Fig. 4 (not shown), and parallel angled slits (27), Fig. 5 (not shown). A tube producing die, Fig. 6, particularly intended for film-blowing, has radial slits 30 crossing circular slit 29 defined by sections 31, 32. Typical dimensions are:-width of slits 29 and 30, 0À3mm.; length of radial slits 1-2mm. Extrusion at an angle to the axis of the die may be effected using a die, Fig. 8 (not shown), having a mandrel (33) co-operating with section (34) whose common axis is (a-a). To adjust the flow direction of the extrudate and to allow the die to be unblocked, the sections may be relatively movable in the embodiments shown in Figs. 2, 3 and 8 (not shown). Materials mentioned are polystyrene, polyvinyl chloride and polypropylene.
