Title: Signal change detector
IPC: G11B5/55
Filed: 1961-05-09
Abstract: 962, 731. Digital data storage. SPERRY RAND CORPORATION. May 9, 1961 [May 27, 1960], No. 16901/61. Headings G4C and G4M. [Also in Division H3] In an arrangement for positioning a magnetic head in correspondence with a desired track on a magnetic data storage drum, both coarse and fine positioning are employed, but if the next address is within the same coarse position as the preceding address, as detected by a comparison circuit, then the coarse positioning apparatus is not activated. The comparison circuit comprises a plurality of bi-stable elements to which are applied the successive coarse addresses simultaneously with reset pulses. As described, for a drum having 1000 tracks, the hundreds, tens and units digits which are in binary coded form, are applied to blocks 36, 38 and 28 respectively, the blocks 36, 38 being connected to comparators 52, 54, Fig. 3, whose outputs are applied to an "or" gate which is connected to a flip-flop 62. If a new address differs from the preceding address in the hundreds or tens digit, the flip-flop 62 is set and applies an output to a control circuit 24 which causes a pawl (not shown) to be retracted from a rack 26 thereby disengaging the head carriage (Fig. 1, not shown) to enable the head 14 to be driven under the control of a servo circuit 25 which is supplied with an analogue representation of the hundreds and tens digits obtained from a digital-to-analgue converter 42. When the coarse position is reached, a signal from a circuit 29 resets the flip-flop 62 and the pawl is re-engaged with the rack 26. The units digit applied to a digital-to-analogue converter is now effective to move the rack 26 against the action of a spring to the required fine position. Comparator circuits, Fig. 3. Each comparator 52, 54, Fig. 3, comprises four bi-stable magnetic cores 74 each having an input winding 76, a reset winding 78 and output winding 80, the input winding 76 having twice the number of turns and being wound oppositely to the reset winding 78. Successive binary-coded decimal digits are applied to four terminals 82 in synchronism with a reset pulse on a terminal 85. Assuming the previous digit was "O" the core 74 will be a state of negative saturation, and a "O" input at 82 together with the reset impulse at 85 produces no change, but a "1" input at 82 together with the reset impulses switches the cores to positive saturation and produces an output at 88. Assuming the previous digit was "1", the core 74 will be in a state of positive saturation and a "1" input at 82 together with the reset impulse at 85 produces no change but a "O" input at 82 together with the reset impulse causes the core 74 to be reset and produce an output at 88. Thus an output at 88 is produced in the event that the input at 82 differs from the preceding input. Specification 910,636 is referred to.

Title: Method of and apparatus for storing sugar liquor

Filed: 1959-05-22
Abstract: 898,034. Preserving sugar liquor. WHITE, T. W. Aug. 22, 1960 [May 22, 1959], No. 17469/59. Class 49. In the preservation of sugar liquor, carbon dioxide gas is introduced into a closed sterilized vessel until a predetermined pressure is reached, air displaced by the carbon dioxide is vented from the top of the vessel until the carbon dioxide alone remains in the vessel and then sugar liquor is pumped into the vessel with displacement of the carbon dioxide until the vessel is filled to the desired level. Referring to the Figure, carbon dioxide is supplied through nozzles 4 to a vessel 1 from a supply pipe 3 whose control valve 7 is pressure-loaded through pipe connections 16 and 10 by the pressure within the vessel, whereby a volume of withdrawn liquor is replaced at constant pressure by carbon dioxide. A drier 15 containing desiccant material such as silica gel may be intercalated in the branch pipe 10. When sugar liquor is being introduced through an inlet 2, the carbon dioxide displaced is arranged to pass through a balancing pipe 13 to a closed supply vessel (not shown) from which excess pressure is shifted off. The vessel may incorporate a reserve tank (not shown) to provide a supply of cold liquor from an amount introduced previously, in case' the liquor being introduced is too hot for an immediate use.

Abstract: 684,824. Photographic roll-flim cassettes. LEITZ GES., E. July 25, 1951 [July 31, 1950], No. 17591/51. Class 98 (i). The cassette has a mouth closable resiliently in a light-tight manner, and comprises two trough-like members hinged together and each carrying one jaw of the mouth, the members having side walls which overlap when the cassette mouth is closed, the members and therefore the jaws being spring-urged together so that the mouth tends to assume its closed position. As shown, the cassette, made, e.g., of plastic or metal, comprises two trough-like members 1, 2, each with a jaw 1a, 2a, hinged together at 3, the hinge being covered by, or comprising, a strip 4 of resilient material such as natural or synthetic rubber. A strip 5 of similar material extends across the strip 4 so as to urge members 1, 2 together. The jaws 1a, 2a have waved surfaces which grip the film when the cassette is closed. The members 1, 2 have overlapping side walls having ribs 6, 7 forming a tapering channel. When the closed cassette is placed in a camera, a pin on a disc rotated by the camera closing key passes between the ribs 6, 7 and moves the jaws 1a, 2a apart a little to allow the film to move between them without coming into contact with them. Leaf-springs 12a, 12b may be provided within members 1, 2 to keep the film tightly coiled, without affecting the closing action of the strip 5. These springs may bear on parts of the film having no images, e.g. on the perforated margins thereof. In a modification, members 1, 2 are urged together by a spring wire having a central portion parallel and close to the hinge, and portions at right-angles connected one to each of the members. The cassette may be loaded either by feeding film in between the jaws and winding it on a spool, or by opening the jaws so wide that a spool having film wound thereon may be inserted.

Motors, controlling; exciting. -- Speed redue tion, for example to a " creeping " speed, in a winch or like electric motor is produced by coupling the motor armature to a squirrel-cage or other eddy current brake working in a continuous-current field and arranging that concurrently with the energization of this field, resistance is inserted in the armature circuit of the motor. The invention is applicable to continuous or alternating-current motors. Fig. 2 shows a continuous-current motor 5 driving a winch drum 3 and coupled to an eddy current brake 6 having continuouscurrent fields 7. A resistance 24 is connected in series with the armature 5, as described below, when the brake is energize. For normal operation, a switch 8 is closed and this, through the relay 9, completes the motor field circuit between the points 11, 16 and the armature circuit in parallel therewith through the starting resistance 12, this resistance being cut out, for starting, by an arm 19 on the core of a solenoid 18. A relay 14 normally rests so as to close the contacts 13, 15 and' to shortcircuit the auxiliary resistance 24. For braking and giving an increased " creeping " torque, the switch 20 is closed, thereby opening the relay contacts 13, 15 to connect the resistance 24 in series with the motor armature and closing the contacts 22 to energize the eddy current field at 23. The melay 14 at the same time short circuits the switch 8.

Abstract: In a process for preparing a silica-alumina cracking catalyst, an alkali metal silicate solution having a silica-alkali metal oxide weight ratio of 3:1-3,4:1 is contacted with carbon dioxide in an amount sufficient to convert substantially all the alkali in the silicate to alkali metal carbonate and thus form a silica hydrogel containing the dissolved carbonate, the resulting mass is commingled with a slurry containing an aluminium sulphate and unreacted aluminium hydroxide in which the mole ratio of sulphate to aluminium is less than 3:1 and at least 1,5:1 in an amount sufficient to provide up to 40% active alumina in the final catalyst, the carbon dioxide evolved is preferably recycled to the gelation step, a basic precipitant is added if necessary to the slurry to complete precipitation of alumina and the resulting product is purified and dried.  The alkali metal silicate is preferably Na2SiO3 and the slurry may be formed either by reacting Al(OH)3 with less than the equivalent quantity of a mineral acid or by adding Al(OH)3 to an aluminium sulphate solution.
