Title: Self-locking safety belts
IPC: B60R22/46
Filed: 1968-11-11
Abstract: 1,210,323. Safety harness. SIGMATEX A.G. 11 Nov., 1968 [22 June, 1968], No. 53224/68. Heading A3V. A vehicle safety belt 8 is wound on a reel 1 driven through a self-locking transmission 4, 5 by a reversible motor 7. The latter may be clockwork, hydraulic or pneumatic but is preferably an electric motor controlled by the tension in the belt. This motor drives the reel through an electromagnetic clutch and a self-locking worm 5 meshing with a worm wheel 4. The belt 8 passes from the reel through a tension-responsive means 9 having guide rollers 20, 21 and a feeler arm 12 biased downwardly in slot 11 by a spring 13. A pull on the belt in direction 22 causes the belt loop passing under feeler arm 12 to raise the latter and operate a switch 17 which actuates motor 7 to pay out the belt. When the latter becomes slack, spring 13 biases the arm 12 to operate a switch 15 which causes the motor to wind in the belt until the arm 12 occupies an intermediate position where the motor is stopped and the reel is locked by the worm 5. When the belt is fully retracted, a feeler arm 25 riding on the wound belt opens a switch 26 to de-energize the electromagnetic clutch. This permits a quick withdrawal of the belt for strapping it on. Alternatively the motor 7 may be driven initially at high speed but when the buckle of the belt has been closed, a resistance is inserted in the motor supply to reduce the speed. An electric switch associated with a time delay may be provided in the backrest of the vehicle seat to delay retraction of the belt. In other embodiments, Figs. 4, 5 (not shown), the re-wind switch 15 is actuated by the brake pedal or by means (34) responsive to acceleration or retardation of the vehicle.

Filed: 1966-11-29
Abstract: 1,164,630. Core data stores. HONEYWELL Inc. 29 Nov., 1966 [4 Jan., 1966], No. 53467/66. Heading G4C. [Also in Division H3] A selector unit, for example for a core storage matrix, comprises a plurality of multi-emitter transistors, a plurality of loads connected at one end to a respective emitter and at the other end through a switching device to a supply terminal, the switching device being common to the load connected to an emitter of another transistor. As shown in Fig. 1 the loads are transformers for connection to amplifiers feeding the matrix lines. The primary windings are energized when positive pulses are applied through diode AND gates such as 56-58 to the base of the multi-emitter transistor and concurrently a NAND gate, such as 75, 76, is pulsed to connect the column wire to earth. The multi-emitter transistor provides isolation between the columns. A Fig. 2 circuit is used as the X decoding selector and as the Y decoding selector in the memory system shown in Fig. 3. The magnetic core matrix 90 is controlled by a read/write matrix using two diodes at each intersection and the X, Y decoding selectors receive their inputs from a timing and control circuit and from address or data registers. The multi-emitter circuits 50 of Fig. 2 may alternatively take the form shown in Fig. 3. When positive signals are received at 18, 20 and 21 transistor 26 conducts causing 31 to saturate to an extent controlled by a feedback transistor 41 utilizing as its emitter and base the collector and base respectively of 31. Diode connected transistor 27 assists rapid switch-off of transistor 26. The lower multiemitter transistor is rendered conducting by concurrent pulses at 20, 21 and 22.

Title: Method and apparatus for cleaning and fractionating a pulp suspension
IPC: B04B3/00
Filed: 1967-11-29
Abstract: 1,216,088. Particle suspension fractionation; centrifugal separators. KARLSTADS MEKANISKA WERKSTAD A.B. 29 Nov., 1967 [1 Dec., 1966], ,No. 54263/67. Headings B1D and B2P. A particle suspension (e.g. wood plup) is given a cylindrical or conical Couette flow (i.e. the type of flow generated in a fluid contained between a pair of coaxial walls when one is rotated relative to the other); suspension rich in undesirable particles is removed from the outer zone of the Couette flow; and suspension rich in desirable particles is screened centripetally from the inner zone. The apparatus claimed comprises a cylindrical or conical housing 1; a screen drum 3 comprising one or more screens 17; an inlet 25 for suspension, a rejects suspension outlet 37; an accepts suspension outlet 45; the screen drum 3 'being rotatably mounted for the induction of a Couette flow. As described, suspension flows in at 25; through a bar screen or perforated plate 33; a rotary flow is induced by vanes 23 supported by a rotating shaft 15; and into the annular space 5. Pairwise counter-rotating Taylor's vortices are formed (these may be imagined as helical flow paths about axes which are themselves curved to form circumferences about shaft 15) which tend to keep those particles possessing lower sedimentation velocities in suspension. The centrifugal forces induced by the Couette flow tends to project the heavier (impunity) particles outwards, and this effect is felt more strongly the nearer to screen 17 the particles happen to be located, owing to the greater flow velocity there. Thus the heavier particles leave at 39, whereas the desirable particles pass through screen 17, which is kept clean by fixed back-pulse-inducing vanes 47, see also Fig. 2. A vent arrangement may be provided 'to allow released air to escape. In a second embodiment (Fig. 3, not shown) the screening surface is built up from screen plates (49) so as to present a horizontally ribbed {instead of smooth frusto-conical) screening surface (55); and there are dilution water apertures (61) in the housing wall 1.

An apparatus for separating a mixture of two components comprises a cylindrical separating chamber 4, Figs. 1 and 2, an inlet 5 for the mixture opening into the cylindrical wall in a non-radial direction, e.g. tangentially, so as to impart to the mixture a rotary movement about the axis of the chamber, coaxial tubular projections 7 extending into the chamber from its end walls 6 for the discharge of the lighter component and apertures 8 in the regions adjacent the end walls for discharge of the heavier component. The apparatus is particularly suitable for separating steam-water mixtures in a steam generator. As shown, separating chambers 4 are located in a horizontally arranged tubular header 1 of a steam generator with their axes parallel to the header axis. Alternatively their axes may be coaxial with or at an angle to the header axis. A number of steam-water mixture inlets 5 may be provided at one and the same peripheral line for each chamber 4. Each chamber 4 may have a greater diameter in the middle than at the ends and its diameter may decrease uniformly towards each end. The tubular projections 7 may incorporate baffle plates as flowcorrecting means. The header has water outlet conduits 2 and steam outlet conduits 3. In Fig. 3, partition walls 9 are welded into the header 1 to divide it into steam-conducting chambers 10 and water-conducting chambers 11. The separating chambers 4 are mounted in the chambers 11 and are spaced from the partition walls 9 by gaps 14 constituting the separated water outlets. The water discharge conduits 2 may lead to a steam-water separating vessel with constant water level in which any steam entrained with the water is separated and conducted each of the chambers 10 via conduits 16. Any water entrained with the steam discharging via the tubular projections 7 into the chambers 10 can flow out through the conduits 16. In a modification, Fig. 4 (not shown), partition walls (9) with the separating chamber (4) and the tubular projections (7) and part of mixture inlet conduits (5), (13) are secured by welding in a tubular member (15) which is provided with a water outlet opening and is fitted as a unit within the header. In Figs. 6 and 7, the annular space between the separating chambers 4 and the inner wall surface of the header 1 is subdivided by radial partition walls 19, 20, 21 into a water-discharge chamber 22, steam-discharge chamber 23 and steam-water mixture-inlet chamber 24, these chambers extending over the entire length of the header. Each chamber has a tangential inlet 17 for the steam-water mixture. Tubular elements 25 are arranged between the individual separating chambers 4 and are provided with upper longitudinal slots for the discharge of steam issuing from the tubular projections 7 into the steam-discharge chambers 23, the steam then flowing via conduits 29 into downstream boiler heating surfaces.
