Title: Improvements in computing weighing scales
IPC: G01G19/42
Filed: 1921-04-13
Abstract: 182,931. Marks, E. C. R., (Toledo Scale Co.). April 13, 1921. Computing-apparatus. - In a computing weighing-scale comprising two commodity receivers connected to a lever at one side of the fulcrum thereof and also connected to loadbalancing and indicating means, the commodityreceivers are connected to the lever at different points means being provided for changing the lever multiplication between the commodityreceivers and the load-balancing mechanism. The usual platform 2 is coupled by a draw rod 5 to a lever 7 mounted on a fulcrum 8. The lever carries a slide 15 coupled by a rod 37 to an automatic load-balancing mechanism actuating an indicating-hand 41. The load-balancing mechanism is contained within a casing 4 slidable upon the top of the column 3 by operating a hand wheel 21. The casing 4 has a slotted arm 22 for simultaneously moving the slide 15 and thus altering the leverage between the platform and the load-balancing mechanism. A pan 12 at the end of the lever receives specimens of the articles which are to be counted. The dial is marked with a series of concentric scales having different ranges. In using the apparatus, two articles, or a multiple thereof, are placed in the pan 12, and the casing 4 is moved until the indicating-hand coincides with the 100 graduation on the inner dial scale. The articles are removed from the pan 12 and a quantity of similar articles are placed on the goods platform. The indicating-hand then reads the number of these articles on the particular concentric scale which corresponds to the number of articles used in the pan 12, the indicating-hand being inscribed with numbers to facilitate the selection of the correct scale. In a modified chart, for use when the pan 12 always receives a constant number of articles each concentric scale is tinted between the 100 and 200 graduation marks. For ordinary weighing the slide 15 is moved to its extreme right-hand position and the weight is read off on the inner dial scale. When moving the slide the lever 7 is held in mid-position by a hand-operated catch 26. The. position of the casing 4 on its support is indicated by a pointer 47.

Title: Improvements in or relating to hydrodynamic torque converters
Inventor: COTTERILL JOSEPH HOBSON
IPC: F16D33/20
Filed: 1971-04-23
Abstract: 1,274,404. Hydrodynamic torque converter. J. H. COTTERILL. 23 April, 1971 [8 Feb., 1971], No. 10900/71. Heading F2C. In a hydrodynamic torque converter in which the reactor is fixed or, as shown, mounted on a fixed sleeve 29 by a one-way detent 22, the impeller includes fixed blades in the inner impeller core 9, and blades 10 radially movable in unison in slots in the impeller core and outer shell 7, to vary the effective diameter of the impeller to allow the use of the converter in a vehicle drive in which the gear-box may be omitted. The blades 10 are integral with pistons 11 by which they are moved radially in against centrifugal force. Pistons 11 are fluid linked in closed chambers with axial pistons 36 moved together by a single piston 40 supplied with actuating fluid by rotary screw pumps 53 rotated by planetary gear-wheels 58 on their shafts and meshing a sun gear 64 on a sleeve 65 to rotate the gear-wheels 58 or stopping the sleeve 65 by engaging a multiplate friction brake 69. The brake is engaged by actuating an on/off solenoid-controlled valve 71 which directs low pressure fluid from a gear pump 32 to the brake. With valve 71 closed, the brake disengages and the low pressure fluid is directed inside sleeve 65 to a booster centrifugal pump 63 which maintains the screw pump chambers full and directs excess fluid through a bearing 51 to the torus of the converter to provide continuous circulation and cooling of the hydrodynamic converter fluid. Movement of the blades 10 radially outwards is effected by centrifugal force when piston 40 is allowed to move back by allowing pressure fluid to leave the apply chamber via valves 49. Each valve includes a choke 50 maintaining pressure on either side of a valve piston 48 equal until a valve 73 is opened to create a pressure differential across valve piston 48 to open the valve. The valve 73 may be centrifugally actuated or it may be a solenoidcontrolled valve and be controlled together with the apply valves 71 by a single governor control system to govern the driving engine to ensure operation along any prescribed speed-torque or speed-power characteristic.

Title: Improvements in and relating to the lubricating of the bearings of railway and like vehicles
IPC: B61F17/24
Filed: 1925-04-27
Abstract: 243,232. Dear, V. N. April 27, 1925. Gravity-feed capillary action, and force-feed lubricating.-A pump driven from the axle 1 of a railway or like vehicle and enclosed in the axle-box delivers oil from the bottom of the box through a pipe 22 into a raised trough 27, Fig. 3, in the box, from which the oil overflows or is delivered by a wick on to a flexible leather or like pad 34, the end of which is pressed against the journal by a spring 38 acting on a bar 36. The trough is held in position on brackets 28 by springs 30. The pump shown in Fig. 2 comprises a spindle 13 carrying a screw or worm 17 working in a sleeve 18 in a chamber 19. The spindle is driven by a wheel 16 geared directly or through the medium of a chain or belt to a wheel 8, Fig. 1, secured to the axle. Oil is drawn in through holes 20, 23 and is discharged to the pipe 22 through holes 21, 24. As the speed and consequently the oil pressure in the pump vary, the sleeve 18 moves in the chamber 19 under the action of a spring 26, causing the holes 23, 24 to move relative to the holes 20, 21, whereby the delivery is regulated in accordance with the speed. If a plunger pump is used, it may be driven by a lever operated by a projection 39, Fig. 3, on the journal flange 2. The wheel 8 is secured on the hub 4, Fig. 1, of a disc 3 fixed to the end of the axle. The wheel is bored eccentrically and is rotated on the hub 4 until it runs true, when it is secured by a nut 11 which presses a washer 9, which is slidably but non-rotatably mounted on the hub, against the wheel, the washer and wheel being provided with serrated engaging surfaces.

Title: Improvements in or relating to thermally operated release means, applicable to electric switches
IPC: H01H73/30
Filed: 1940-07-02
Abstract: 540,237. Thermostats ; electrically released switches TURNER, L. V. (Talbot, F. A.). July 2, 1940, No. 11163. [Class 38 (v)] [Also in Group XIII] A thermal release, described in connection with a circuit breaker comprises two similar heat sensitive elements each having one end free to deflect, which ends are inter-engaged, one element being displaceable relative to the other to effect a release action of the engaged ends solely under conditions of thermal difference between the elements. In the example, as applied to a switch, the elements comprise helical bi-metallic strips, 5, 17, one, 5, secured at its lower end to the frame 3, the other 17 on a plate 22 sliding on a rod 18, co-axial with a release rod 11 and resting in a socket at its lower end. Rotation of the plate 22 is prevented by a lug 24 riding in a vertical slot in the frame. A spring 21 presses upwards the top plate 16 of the element 17. The rod 11 has a boss 12 at its lower end from which depend two lugs 14 against which the plate 16 is pressed in engaged position. Upon relative rotation of the rod 11, such as on undue heating of the element 5, by an overload heating-coil 41, the lugs 14 slip off the edges of ears 15 on the plate 16, Fig. 7, and the element 17 is pushed upward to disengage contacts 23 on the plate 22 from fixed contacts. To reset on cooling, a bar 33 of insulating material is pressed down against the action of a spring 35, a projection 34 on its lower end bearing on the lug 24 of the contact plate 22 until the ears 15 re-engage below the lugs 14. Just previously the lower end of the bar 33 has pressed on the extension 31 of a spider plate 26, arms 30 on which hold the contacts open until the bar 33 is allowed to rise again.

Abstract: 813,225. Extruding polythene strip. STANDARD TELEPHONES & CABLES Ltd. April 5, 1957, No. 11185/57. Class 87(2). A process for the production of stress-free polythene strip comprises extruding heated polythene through an arcuate die and allowing the extrusion to fall onto the horizontally moving portion of a continuous travelling belt and there to take up the shape, during cooling, of a flat strip. The strip may be trimmed to a pre-determined width in preparation for punching into discs used as insulating means for coaxial telecommunication cables. A strip 11 of semi-annular section is extruded from a die 9 and falls onto a belt 1, driven by a capstan 2 and running on rollers 3, 4, 6, 7 and tension applying roller 5. After natural cooling on the horizontal portion of the belt the now flat strip is drawn, on rollers 14, 15, 16, by a capstan 21 through a cooling bath 17 and then through a device 20 to trim its edges. The strip is held in contact with the capstan 21 by a freely running belt 22 on rollers 23, 24 and tension applying roller 25. On leaving the capstan 21 the trimmed cooled strip is drawn over rollers 27, 28 and is taken up by a spool 29. The capstan 2 is driven by a variable speed gear so that the speed of the belt 1 is the same as the rate of extrusion. The capstan 21 is driven by a variable speed gear so that the strip is not tensioned during its passage between the capstans and the spool 29 is lightly driven by a slipping belt to again avoid tensioning the strip. The aperture of the die 9 may be adjusted by screws 38.

Title: Process for the preparation of n-alkoxymethyl polyamides in granular form
IPC: C08J3/14
Filed: 1945-05-07
Abstract: N-alkoxy methyl polyamides are obtained in granular form by adding water to a stirred alcoholic solution of the polyamide, thereby causing the precipitation of a viscous resin-containing fluid, which is then agitated in the presence of water either after separation from the mother liquor or admixed with it, and the resulting hard finely divided granules are then separated from the aqueous phase. The N-alkoxy methyl polyamides, e.g. polyhexamethylene adipamide, polyhexamethylene sebamide and polyamides derived from e -amino caproic acid, are prepared by condensing a synthetic linear polyamide with formaldehyde and an alcohol in the presence of an oxygen-containing acid catalyst, preferably phosphoric acid.  The reaction is stopped by pouring the reaction mixture into a quenching bath containing chiefly methanol, water and an alkali, preferably ammonia.  In the granulation process, the quenched solution is stirred with water, and the resulting viscous resin containing fluid, which separates out, is mechanically worked, in a dough mixer, with further quantities of water, the small granules into which the doughy, resinous mass breaks up after prolonged working being then separated.  On the addition of further water and after continued stirring the granules harden and are separated by filtration or centrifugation.  To obtain the preferred methylol content (i.e. below 0.4 per cent) the quenched solution is treated with an aqueous or alcoholic solution of a methylol-removing agent such as a water-soluble sulphite, hydroxide or carbonate of an alkali metal or alkaline earth metal before granulation, or on prolonged storage in alcoholic ammonia the methylol content is reduced. Specifications 461,236, 461,237, 544,715, 573,482, and U.S.A. Specification 2,130,948 are referred to.

Title: Digital time base correctors for television equipment
IPC: H04N9/896
Filed: 1974-03-16
Abstract: 1465314 Television systems QUANTEL Ltd 14 March 1975 [16 March 1974 (2)1 11793/74 and 11794/74 Heading H4F An arrangement for controlling the writing into a store of digital samples of a television signal subject to timing errors, e.g. a signal from a video tape recorder, includes an input oscillator which provides write pulses and which is started at the beginning of each video line and is stopped at the end of each line after emitting a predetermined number of pulses. The start is controlled by the line sync pulses and may be adjusted by reference to the colour burst. The oscillator pulse rate may be varied to take account of variation in the line duration. The input video signal is digitized by an analog-digital converter whose sampling rate is controlled by the pulses from the input oscillator, these pulses also controlling the writing of the samples into the store. Read-out from the store is at a rate controlled by an output oscillator having a fixed pulse rate and which also controls a digital-analog converter which reconstitutes the video signal. In one arrangement of the input oscillator (Fig. 3, not shown) the line sync pulse of the input video signal sets a bistable (13) to cause an oscillatory circuit (10, 11) to generate the pulses. A counter resets the bistable to inhibit further generation of pulses when it has counted the predetermined number. In a second arrangement (Fig. 5, not shown) the video input a, Fig. 7, is supplied to a sync pulse separator (32) and to a colour burst band pass filter (25). The sync pulse triggers a monostablo (31) having an astable period TD1 as shown at b. When the monostable resets, a bi-stable (30) is set. The output of the colour burst filter is as at c and is fed to a zero crossing detector (29) which resets the bi-stable (30), whose output is as at d. A differentiator (34- 36) generates a pulse e at the end of pulse d. Pulse e sets the bi-stable (13) referred to in the first arrangement to cause the generation of pulses as previously described. Since pulse e is related to the phase of the colour burst cycles the phase of the generated pulses is more accurate than if the line sync alone were used. In a third arrangement (Fig. 8, not shown) the pulse frequency of the oscillator (40) is adjusted at the beginning of each line according to the time elapsing between the cessation of pulses used for sampling the preceding line and the starting of pulses for sampling the present line. This time interval varies according to variation in line duration such as result from tape speed variation when the input video is from a video tape recorder.
