Title: Indexing apparatus for recording and transcribing systems
IPC: G06M3/14
Filed: 1975-12-23
Abstract: 1510879 Electromagnetic counters; tape position indicators DICTAPHONE CORP 23 Dec 1975 [27 Dec 1974] 52675/75 Headings G4D and G5R A reversible electromagnet counter has a pair of electromagnets 28,48; a pair of armatures 106 pivotally mounted in a frame 62 and having extending arms 102; a pair of pawls 96, 98 pivoted at 108 to the arms 102 and each having a first portion 124 which drives the teeth of a respective ratchet wheel 88, 90 fixed to a shaft 78 and a second portion 125 which engages another tooth of the ratchet, at the end of movement of the armature towards the electromagnet, to limit the rotation of the ratchet. In Fig. 5 the shaft 78 carries and drives number wheels (not shown) visible in a window 154 to directly indicate the difference between the numbers of pulses applied to the two electromagnets. In Fig. 4 the shaft 78 carries a pinion 86 integral with one ratchet 90 and which drives a gear 136 on the shaft of a potentiometer 130 which is coupled to a meter and voltage to obtain an indication of the difference. The counter is employed in a dictation machine; pulses are derived from holes in magnetic recording tape by a phototransistor (Fig. 1, not shown); the counter adds pulses during the recording mode and substracts pulses during the playback mode thus giving an indication of the amount of dictation remaining to be transcribed.

Abstract: 1442127 Supporting and driving conveyer belts by magnetic means BRITISH STEEL CORP 16 Nov 1973 [16 Nov 1972] 52993/72 Heading B8A [Also in Division H2] A conveyer belt 10 driven by linear motors 13, 15, has its side edges supported in respective guides 14, each of which has an arrangement of magnets 19, 19, 21, which support by magnetic repulsion magnets 20 carried by each of a series of belt-edge support members 13. The magnets 20 are surrounded by a flexible moulded channel 22. The magnets 19, 19 may be replaced by guide wheels (24), (24), (Fig. 3, not shown) or by pneumatic levitation cushions (27), (27) (Fig. 4, not shown). In a further arrangement, the magnet 21 may be replaced by an electromagnet (29) (Fig. 5, not shown). The latter is part of a series-resonant circuit, and is fed by an alternating voltage source. Movement of the support member 13 away from the magnet 21 causes the circuit to approach resonance and increase the magnetic force. The belt may have a liner 16. The guides 14 may be brought together downstream of a loading shoot (30) (Fig. 6, not shown). One edge of the belt may be allowed to fall freely by the action of guide rollers 51 (Fig. 11) at a discharge station. This causes the belt to hand vertically from its supported edge until it comes around again to a feed hopper 30, after which the belt is once more guided into tubular form.

Filed: 1973-11-26
Abstract: 1440798 Applying ferrules to sheathed ropes BRIDON Ltd 26 Nov 1974 [26 Nov 1973] 54739/73 Heading D1T A method of pressing a ductile ferrule 7 onto a sheathed wire-rope 5 comprises threading the sheathed wire-rope through the ferrule, and then placing the ferrule between dies 11, 11 which are brought together to define a working bore which is substantially a surface of revolution, the working bore increasing in diameter from the middle to the ends. In Fig. 5 the bore has a cylindrical middle portion 15. The end portions 19, 19a are of equal diameter and are joined to the portion 15 by chamfered portions 18, 18a and 17, 17a. Alternatively the chamfered portions may be replaced by a tapered portion exponentially increasing in diameter. The specification states that when a ductile ferrule is pressed onto a sheathed rope by the dies, the sheathing is thicker at the ends of the dies during pressing and serves as a seal to prevent the ferrule flowing inwards at its ends. The end portions 19, 19a provide a reduced pressing action at the ends to accommodate plastics material extruded from the middle and the accumulated plastics material seals the bell-like ends of the ferrule against the ingress of liquids or gases. The cylindrical middle portion 15 may have a length that is zero to 50% of the total length of the portions 15, 17, 17a 18 and 18a.

Abstract: 548,257. Drying oils. DISTILLATION PRODUCTS, Inc. March 28, 1941, No. 4167. Convention date, April 9, 1940. [Classes 32 and 91] Imrproved drying oils are obtained from drying oils, particularly oils of rather low iodine number such as fish oils, by removing an undesired fraction therefrom by high vacuum unobstructed path distillation and subjecting the residue to a bodying or polymerisation treatment. Drying oils specified comprise the ordinary drying oils and others of iodine numbers above 120; the former exemplified comprise linseed, soya bean, oiticica and walnut, and the later comprise fish oils such as menhaden, sardine, pilchard and shark. The bodying treatment usually comprises either heating with or without catalysts, preferably in the absence of oxygen, such as in an atmosphere of nitrogen, or oxidizing by air blowing. The molecular still employed may be the usual gravity flow type or the centrifugal distributer type of apparatus, such as described in Specification 482,883, wherein the distilland is introduced on to the centre of a heated rotating disc or plate. The usual pressures in such apparatus are used, and the preferred temperatures range from 150‹ to 325‹C., 175‹ to 250‹C. for the gravity flow apparatus and 180‹ to 275‹C., for the centrifugal distributer apparatus. The proportion of the fraction removed is either 2 to 12 per cent. or 30 to 50 per cent. The resulting drying oils may have added thereto a small amount of drier such as a mixture of lead, manganese, and cobalt naphthenates.

Title: Method and device for the acoustic steering of torpedoes to a target
IPC: G05D1/12
Filed: 1967-12-05
Abstract: 1497040 Automatic control FRIED KRUPP GmbH ATLAS-ELEKTRONIK BREMEN 5 Dec 1967 [24 Dec 1966] 55362/67 Heading G3N A method of steering a submarine torpedo towards a target in which the bearing of the target is taken acoustically by a position finder placed either at the torpedo or at the station from which the torpedo is launched and in which the steering is corrected according to the position values obtained by the acoustical bearing of the target, is characterized in that the speed of the torpedo is reduced from time to time during the run of the torpedo and that the position values obtained by the position finder during the periods of reduced speed are used for correction of the steering. Owing to the noise emitted by a torpedo when it is travelling fast, the range of target detection by the torpedo is very limited, but by providing the reduced speed intervals, this disadvantage is overcome. As shown in Fig. 1, a torpedo driven by a motor 4 is steered by means (not shown) controlled by acoustic signals derived from the scanning of a directional receiver 3 mounted on the torpedo head 1 and having a search characteristic 2. The steering may be according to a dog curve Fig. 5 (not shown) or proportional navigation procedure Fig. 6 (not shown). The periods of reduced torpedo speed are obtained by a changeover switch 5 which is moved from the maximum speed position in which the voltage U 1  is applied to the motor 4 to the position shown in which a reduced voltage U 2  is applied to the motor. The switch 5 is controlled by a cam 8 driven by a motor 9, the speed of this motor being varied by a switch 10 having a contact a 1  movable between a position of maximum voltage U 4  and the position shown of lower voltage U 5 . Contact a 1  is controlled by a relay A and the latter is energized by the receiver 3 immediately a target is detected so that the contact moves from the slow to the high speed position, a holding contact a 2  maintaining the contact a 1  in that position whereby motor 9 continues to operate at the high speed. A relay B energized by the receiver 3 operates with a time delay caused by circuit C, R to move a contact b 1  to the maximum voltage U position so that with increasing signal-to-noise ratio the length of the reduced speed periods of the motor 4 is reduced and also the extent of the speed reduction is reduced. A contact 13 synchronizes the movement of the cam 8 with the receiver 3 to ensure that the commencement of a low speed period coincides with the search characteristic 2 being at one of its two limit positions.
