Title: Improvements in or relating to frequency-shift digital transmission systems
Inventor: HANNON DONALD CHARLES
IPC: H04L27/20
Filed: 1962-01-03
Abstract: 1,026,161. Data transmission. PLESSEY CO. Ltd. Dec. 28, 1962 [Jan. 3, 1962], No. 225/62. Heading H4P. In a frequency shift telegraph transmitter the change from one frequency to the other occurs when the gradients of the instantaneous signals are similar. Mark and Space pulses control an oscillator operating at bit frequency which controls a second oscillator operating at half the bit frequency. Both oscillators produce two outputs 180 degrees apart. An arrangement of gates fed by toggles controlled by the Mark and Space signals ensures that the transitions are as indicated above by selecting one or other of the outputs of the appropriate oscillators. In a modification, the Mark pulses have twice the duration of the Space pulses, the circuitry being modified to ensure that each bit is represented by a complete half-cycle.

Title: Improvements in or relating to mechanical joints between adjoining plates located substantially in one plane
IPC: F16B5/00
Filed: 1947-01-03
Abstract: 641,230. Seaming non-metallic sheets. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Jan. 3, 1947, No. 241. Convention date, Oct. 30, 1943. [Class 42 (i)] [Also in Groups X, XV, XXII and XL (c)] In joining two plates of insulating material &c. in substantially one plane, e.g. in toys or chassis of electrical sets, in which at least one plate has projecting parts extending over the other plate, these parts are bent about lines parallel with the length thereof so that they are normal to the adjacent plate surface. Each plate may have such parts extending over the other plate and may finally be secured by bending, gluing, &c. A plate 1 having one or more tags 2 projecting from its edge E to which another plate is to be joined, has an inclined cut 3 or a right-angled cut 64, 65, Fig. 9, made at each tag so that these can be bent at 5 to be normal to the plate 1. Another plate 11, Fig. 3, may be similarly formed and assembled with the first, relative movement in the plane of the plates being prevented, if desired, by gluing &c. the tags to the plates they overlap. If the second plate is of glass, ceramic material, or other material not easily deformed, a slot 24, Fig. 4, is formed adjacent each line 5 so that, when the tags are bent up, the second plate 35, Fig. 6, can be engaged in the slots 24, overlapping the plate 1. If a slot is cut in the edge of the plate 35 at each tag the plates can be so overlapped that the holes H, Figs. 3 and 11, are covered. Otherwise these holes may be covered in any known manner. If the tags of two plates are cut as in Fig. 9 and the plates are assembled with the tags of one engaging the tags of the other, Fig. 11, the tag ends E projecting may each be bent over the end of the adjacent tag to secure the plates against any relative movement. In joining a thin plate 40, Fig. 7, to a thick plate 41, this has projections 46, 47 extending over the plate 40 which are formed by applying local pressure normal to said plate 41. The tag 43 is similar to the tags 2 but the tag 42 at the corner of the plate 40 is bent up by bending the whole edge 44. Fig. 8 shows a thin plate 50 secured between parts A, B of a thick plate 51, four tag or projecting parts being bent up by bending the edges 53, 56.

Title: Improvements in contacts for electric circuit breakers, switches, connectors and the like
IPC: H01H1/38
Filed: 1933-01-06
Abstract: 409,085. Switch contacts. WHITEHEAD, G. E., Rhiwbina Hill, Rhiwbina, near Cardiff, and WHITEHEAD'S ELECTRICAL INVENTIONS, Ltd., 24, Western Mail Chambers, Cardiff. Jan. 6, 1933, Nos. 541 and 3770. [Class 38 (v).] High - tension switches; arc-rupturing devices.-A socket contact comprises a housing 101, between a shoulder 103 of which and a retaining ring 104 are circularly-stacked laminµ 105, preferably of copper, the inner edges of which are radial to, and contact with, a plug contact 106 (Fig. 2), whereas the outer edges bear on the housing 101. In the case of large contacts, phosphor-bronze or steel laminµ 108 may alternate with laminµ 105. As applied to main contacts of the switches described in Specifications 392,926 and 392,930, the laminµ 105 are arranged in the enlarged arc mouth 101 of the housing 21 and co-operate with a part of the movable plug contact 109 which is of larger diameter than the tip 5, which is threaded at 110 into the plug 109. Four ducts 111 permit the free circulation of oil, as shown by the chain-dotted line, whereas in opening the circuit, when the parts reach the chain-dotted position shown, the incipient arc is quenched by the flow of oil round the tip 5, as shown by full-line arrows.

Title: Improvements in Stop Mechanism for Talking Machines.
Inventor: DUNCAN RAYMOND
IPC: G11B17/02
Filed: 1917-01-11
Abstract: 113,120. Duncan, R. Jan. 11, 1917. Periodic; electric and magnetic; actuated or applied by springs.-In automatic brake-mechanism for talking-machines, relatively-movable parts of the sound-box are arranged, when the stylus reaches the final groove, to control the stop mechanism, preferably by electrical means. A floating arm 25 carrying the stylus is mounted on the sound-box 24 by a spring 27 and insulating block 26, and carries a pin 30 which, when the stylus is in action, lies centrally within a loop 29, Fig. 5. The circuit of a battery 48 includes the floating arm 25, horn 22, switch 52 and an electro-magnet 42 controlling a brake detent 36, Fig. 4. When the stylus reaches the end of the record groove, the friction of the record gives a sudden inward movement to the stylus, thereby causing contact to be made at the parts 29, 30; and the resulting energization of the magnet 42 withdraws the detent 36 and allows a spring 41 to apply a brake block 34 to the inner surface of the turntable rim. The brake lever 31 is pivoted on a pin 32 and carries a wedge block 47, which, when the brake is off, closes a switch 44, 45 in the battery circuit. The brake detent 36 is pivoted on a pin 37 and has a notch 40 which engages with a lug 35 when the brake is off. The outer end 38 of the detent 36 forms the armature of the magnet 42 and is provided with a finger-piece 39 by which the brake lever may be unlatched at any moment.
Patent GB-646588-A (GB)
Title: Respiratory devices
IPC: A62B9/02
Filed: 1948-01-08
Abstract: 646,588. Respiratory appliances. BENDIX AVIATION CORPORATION. Jan. 8, 1948, No. 667. Convention date, Jan. 22, 1947. [Class 81(ii)] In a respiratory device for use at high altitudes nested pressure responsive members, which expand on decrease in ambient pressure, sequentially apply an increasing force on the respiratory responsive member of a demand regulator, to open the demand valve as the ambient pressure decreases. In the demand regulator shown, oxygen enters through a conduit 13 and passes through a pressure reducing valve 15 actuated by a pressure-responsive element 18. It then passes to an expansion chamber 22 from which it escapes under the control of a demand valve 24 actuated by a respiratory responsive diaphragm 30. Inspiration by the user through a mask attached to outlet 14 causes a rarefaction in the casing 11 so that the diaphragm 30 bends inwards and lifts the valve 24 off its seating to permit the flow of oxygen. This oxygen issues through a jet 33 and, by means of a venturi 34 entrains air entering through orifices 38. As the altitude increases an aneroid 40 expands so that a valve plate 41 gradually reduces the quantity of air admitted and ultimately cuts it off completely at 32,000 feet. At approximately 18,000 feet, however, an aneroid 58, mounted within a larger aneroid 53 begins to expand and, through a light spring 75 and collar 78, exerts a gradually increasing thrust on the diaphragm 30. tending to hold the demand valve open. At the same time a ring 80, around the collar 78, and carried on a heavier spring, is moved downwards around the collar, so as to be just clear of the diaphragm 30 when aneroid 58 is fully expanded at 22,000 feet. Thereafter the outer aneroid 53 expands and lowers the ring 80 against the diaphragm on which it exerts an increasing thrust, thereby further raising the pressure of oxygen in the chamber 11. In the fully expanded state of aneroid 53 the head of a central screw 63 bears against the stud 71 on the diaphragm and although no further expansion takes place it exerts an increasing thrust which is counterbalanced by the pressure of oxygen in the chamber 11 on the lower face of the diaphragm. This pressure causes the peripheral area of the diaphragm to flex outwards against an annular stop 82 and the effective area of the diaphragm is thereby reduced to that amount which is clamped down by a metal disc secured to the stud 71 and the surrounding annulus between this disc and the part against the stop 82. Consequently in order to counterbalance the thrust of the aneroid on the stud 71 a still higher pressure of oxygen is built up in the chamber 11, this being greater than would be reached if the full area of the diaphragm 30 were effective; 72 inches water gauge being produced at 100.000 feet. Specification 582,141 is referred to.

Abstract: 1368722 Air filters in grain dryers H BAUDOT 5 Jan 1973 [15 Feb 1972] 685/73 Heading BIT [Also in Division A2] A filter curtain 16 in a grain dryer, for filtering air containing entrained solid material, extends transversely to the air flow and is made up of vertically disposed rectangular panels of filter material side-by-side, the panels being mutually connected, each panel being folded around a correspondnig vertical slackenable member 5 to produce a V-shape in horizontal cross-section, the apex of which projects upstream of the air flow. The ends of adjacent panels of material, e.g. of cloth gauze, are deformed around flanges 6, 7 of a channel member 8 by spring clips 13, 15, the member 8 acting as a dust spout for the dust to drop to the bottom of the curtain 16. Any dust remaining on the panels is removed by the members 5, e.g. cables, being slackened and then shaken.

Title: Improvements in refining and otherwise treating oils, fats and tars
IPC: C10G31/08
Filed: 1921-01-07
Abstract: Oils, fats, liquid or solid hydrocarbons, tar, and tar oils are refined by subjecting them to intensive mechanical disintegration, preferably in a colloid mill as described in Specification 155,836, with a non-solvent such as water to form an emulsion, and afterwards separating the emulsion from colloidal and other solid material, preferably by ultra-filtration under high pressure.  The emulsion may be formed in water in the presence of a heavy metal or earth compound such as barium hydrate.  Examples are given of the treatment of cotton-seed oil, a mineral oil, and of wood tar.  The oil emulsions after ultra-filtration are coagulated by addition of a reagent, for example neutral salt or acid, or by heating.  Tar, after mechanical treatment with water, is allowed to settle, in order that coarse mineral impurities may deposit, after which the emulsion is subjected to ultra-filtration, the pitch remaining on the filter.
Patent GB-790275-A (GB)
Title: Panel feeding machine particularly for use in the manufacture of storage batteries
IPC: H01M10/14
Filed: 1956-01-10
Abstract: 790,275. Feeding panels. WINKEL. H. C. Jan. 10, 1956 [Jan. 19, 1955], No. 837/56. Class 117 A machine for feeding battery elements from a stack comprises a platform 29 supporting the stack, means 113 for moving the platform horizontally to feed one battery element at a time from the stack, a plurality of vertically extending pusher plates 63, 66 arranged adjacent opposite edges of said stack, and lifting means 84 for lifting the plates vertically and moving the lower ends thereof towards each other in time relationship with the movement of the platform so that the stack is lifted just before the platform discharges the lowermost element. As shown, the lowermost element of the stack located in the hopper rests on platform 29, the platform carrying shuttle plate 42 so that when plate and platform are reciprocated together by linkage 112, 113, the plate displaces the lowermost element (or a plurality of lower-most panel elements) to the right into the nip of rollers 46-49 which discharge the element at 53. To assist the action of shuttle plate 42 two features are included. Firstly suction is applied at 33 to perforations 31 formed in platform 29 so that the lowermost panel is flattened as it is fed to rollers 46-49 and the suction may be cut off, appropriately, e.g. as the platform returns to the left. Also the platform may carry a wire grille to accommodate any accumulation of dust. Secondly, the weight of the superposed element is taken off the lowermost element as the latter is fed to the right. This is accomplished by pushers 63, 66. Thus (Figs. 3 and 8) pusher 63 (and similarly 66) is displaced upwardly by cam 84, cam follower 83 and lever 81 pivoted at 82; and, as said pusher moves upwards, its cam 123 moves past stationary roller 121 to cause pusher 63 (and 66) to move inwardly to grip and lift the said superposed elements.
