Patent GB-828398-A (GB)
Title: Improvements in or relating to decoding arrangements for electric pulse code modulation systems
Inventor: BECK ARNOLD HUGH WILLIAM
IPC: H03M1/00
Filed: 1958-04-18
Abstract: 828,398. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. April 18, 1958, No. 12347/58. Class 40 (1). [Also in Groups XL (a) and XL (c)] A de-coding arrangement employing a digit pulse code adapted to represent m different amplitude levels of a signal wave, comprises a cathode-ray tube having an assembly of m decoding elements corresponding respectively to the said amplitude levels, means controlled by the digit pulse combination representing any given level for directing the electron beam on to the decoding element corresponding to the given level, and means for deriving from the last-mentioned decoding element an output voltage or current representing the given element. As described in decoding a six-bit word pulses representing the six bits are applied to terminals 1 to 6, Fig. 1, to cause the cathode-ray tube beam to pass through a particular aperture of an apertured mask 21, then through a corresponding aperture in a " perveance plate " 22 to a collector plate 23 to cause an output at a terminal 35, each aperture of the perveance plate being arranged, either by being covered by a wire grid of an appropriate mesh or by being appropriately dimensioned, to have a different perveance whereby the electron charge that actually reaches the collector plate is different for each aperture so that the amplitude of the output pulse on terminal 35 is representative of the particular aperture and therefore of the particular word being decoded. In a modification the array of different perveance apertures in the perveance plate 22 is replaced by an array of series-connected resistance strips (Fig. 8, not shown), the collector plate 23 is omitted and an output is taken from the seriesconnected resistance strips. This modification is shown in principle in Fig. 7: the series-connected resistance strips can be regarded, with the cathode-ray tube beam, as forming a potentiometer, giving, as before, an amplitude analogue at a terminal 35 of the word being decoded. The bits of the word being decoded can each have three or more amplitude significant states. Reference has been directed by the Comptroller to Specification 652,846.

Abstract: 1377952 Mechanical switches; switch handles G L G BRADSHAW 19 Nov 1971 [27 Nov 1970 30 April 1971 18 June 1971] 56558/70 12359/71 and 28612/71 Heading H1N A switch formed by the knob of, e.g., a gear control lever (not shown), comprises a circular cross-section insulated housing 20 formed in two parts 21, 22 and secured together, e.g. by a bolt 25, for rotation about an axis in line with that of the lever, which may be screwed or clamped into aperture 23, the switch operating with relative rotation of the housing parts 21, 22. A washer 28 holds the halves separated and a coil spring 30 received in hemi-cylindrical recesses 31, 32 in each part of the knob limits the amount of relative rotation of the parts and causes the parts to return to a central position when the operating force is released. Electrical terminals, e.g. 27, are provided in the fixed portion 22, and electrical connection to a moving contact in the rotatable portion 21 may be via the spring 30 or via the bolt 25, a metal bush being provided in the aperture 23 to electrically connect the bolt to the control lever. The spring may also be used as a bridging member for contacts in either part of the housing, and a double spring arrangement may be provided to prevent accidental operation of such an arrangement. A contact member 42, Fig. 5, on the rotatable portion 21 may depend into an arcuate recess 44 in the portion 22 to engage a contact 45 on anticlockwise rotation. The switch may include a thermistor 52, Fig. 8, which is fired on anticlockwise rotation of the rotatable portion and broken on clockwise rotation, the circuit remaining "on" in the central position after being fired. In this embodiment the second spring 50, operated after the main spring 30 by virtue of the additional recess 49 bridges the contacts 47, 48. A successive actuation switch may be formed on the housing, Fig. 10, using a ratchet cam 66 operating sprung roller bridging contacts 63, the sprung peg 70 operating the cam 66 to make and break the contacts with successive rotations in the same direction. Further modifications of switch contacts, i.e. changeover, are shown in Figs. 3, 4, 6, 7, 9 and 11 (not shown).

Abstract: 518,463. De-icing aircraft. WYNNE, J. N., and NORTH BRITISH RUBBER CO., Ltd. April 25, 1938, Nos. 12378.and 33484. [Class 4] Apparatus for preventing ice formation on or de-icing the exposed surfaces of aircraft comprises an elongated substantially rigid chamber e having fitting thereover a rubber tube. or sleeve g maintained at its end portions in fluid-tight engagement with the chamber, the latter having apertures c whereby the intermediate portion of the tube g will expand and contract by alternate increase and decrease of fluid pressure within the chamber. The chamber may be connected to an air-pump or pulsator, and also to a source of supply of compressed air whereby the intermediate portion of the tube can be maintained in expanded condition so as to be subject to vibration under the action of varying wind pressure, this action alone preventing formation of ice when the conditions are not too severe. Alternatively the fluid employed to convey the pressure may be or contain an anti-freezing liquid and the rubber tube may have slits or perforations r, Fig. 9, whereby a limited quantity of anti-freezing liquid exudes on to the exterior each time it is expanded. The rubber sleeve may be divided transversely, for example, by clamping means h, into a plurality of compartments, and the apertures in the chamber so spaced that the expansion and contraction will be wave-like. In a modification, Fig. 5, the chamber is recessed so that porions q of the rubber sleeve are subject to vibration under varying wind pressure when the pulsator is not operating and are drawn into the recesses during the suction stroke of the pulsator.

Title: An apparatus for automatically loading (or positioning) glass sheet at a definite position (or location) on a moving conveyor surface
IPC: C03B33/03
Filed: 1953-05-04
Abstract: 741,109. Endless conveyers. ASAHI GARASU KABUSHIKI KAISHA. May 4, 1953 [May 6, 1952], No. 12378/53. Class 78 (1). Glass sheets are fed to and positioned on an endless conveyer in timed relation with its movement, such that upon release by the feeding device a sheet is fed along the conveyer surface until its forward edge is arrested by a retractable stop on the conveyer, the stop being projected from below the conveyer surface when adjacent the feeding device. As shown, the sheet 30 is placed on a tilting table formed by side bars 11, a lower support 14, and a transverse bar 18 carrying a supporting roller (not shown), the side bars 11 being pivotally mounted on the driving shaft 4 of the conveyer which is composed of slats 2 carried by a pair of chains 1. The bar 18 is carried in slots 17 in the bars 11 so that the position of the supporting roller can be adjusted to support the forward edge of the glass sheet. A crank 29 is driven in timed relation with the driving shaft 4 and is coupled to the tilting frame by a link 24 so that the frame is tilted periodically to deliver a glass sheet thereon to the conveyer surface formed by the slats 2. As the table becomes horizontal, a roller 21 carried by a crank 20 pivoted to each side bar 11 comes into contact with an abutment 23 to cause the forked arm 22 of crank 20 to engage bar 18 and shift it, together with the supporting roller, forwards from under the glass sheet which thus drops on to the conveyer with its rear edge overhanging the end of the conveyer. The rear end of the glass sheet is thus engaged by slats passing from around the driving sprockets 5 on to the conveying run. Owing to the closing of the spaces A, the sheet is inched forwards until the front edge of the sheet engages the stops 9, Fig. 5, normally held by springs (Fig. 7, not shown) within recesses 10 in certain slats 2, but which are raised by the action of fixed ramps 26. After the sheet is wholly supported by the horizontal run of the slats 2, stops 9 are lowered and the sheet is in position for delivery to glass cutting apparatus. The tilting table is adjusted for differing lengths of sheets by a rack-and-pinion connection 15, 16 between a frame carrying the support 14, and the side bars 11.

Patent GB-142867-A (GB)
Title: Improvements in coating machines
IPC: B31B1/74
Filed: 1920-05-08
Abstract: 142,867. Nordell, E. Dec. 18, 1918, [Convention date]. Coating-machines.-In a machine for coating the insides of fibrous cans or other receptacles with viscous liquids such as those used in greaseproofing, means are provided for revolving the inverted vessel while the interior is sprayed with the warm coating material. The excess of the latter is removed centrifugally after the spraying has been stopped automatically. The cylindrical or conical vessel 10 is gripped by several springs 13 fixed to uprights 15 which are pivoted at the upper ends of the supports 17, 18, so that the vessel is able to swing under the influence of centrifugal force into the position indicated in dotted lines in Fig. 2, when the holder is. unlocked by the device 92, 95, Figs. 1 and 5, and the spraying is stopped. The supports 17, 18 are fixed to the plate 19 which rotates about the stationary hollow upright 22 through the agency of the pulleys 21, 29 and band 28 when the clutch 35 connects the power shaft 30 with the pulley 29. Attached to the same shaft as the pulley 29 is another pulley 53 which, together with band 52, pulley 51, and worm-wheel 48, sets the shaft 46 in motion and the wheel 45 and cams 96, 80 attached to it. The clutch is operated by the depression of the lever 37, which however also causes a finger 44 of the rod 41 to leave a notch in the rim of the wheel 45 in which it has been held by means of spring 40. Thus, as soon as the vessel commences to rotate, cam 80 operating the valve 68 causes spraying to begin from the multi-jet nozzle 60 which continues until cam 96, by raising rod 98 and shoe 99, causes pin 92 to release the holder 15 when valve 68 is closed by the cam 80: Rotation ceases when the finger 44, having been riding round the circumference of wheel 45, once more enters the notch therein, thereby enabling the rod 41 under the influence of spring 40 to raise the arm 37 and release the clutch 35. The coating material drains from the walls 71 and shields 74, 75 to the jacketed tank 78, from the bottom of which it is pumped to the receptacle 65.

Title: Improvements in control devices for engine starters
IPC: F02N11/08
Filed: 1934-04-28
Abstract: 440,640. Starting prime movers; actuation of switches. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. April 28, 1934, No. 12886. Convention date, April 29, 1933. [Class 38 (iv)] [See also Group XXXVII] In starting of internal - combustion engines a mechanical connection between a control member of the engine and the actuator of the starter is disabled by devices independently responsive to self-running of the engine and backfire respectively. The accelerator pedal 4 operates through a nut 17 and pivoted latch 16 upon a shaft 19 which is connected through a member 26 to a switch 14 in the starter motor circuit so that when the accelerator pedal is depressed the starter motor is energized. A diaphragm device 36 sensitive to vacuum in the engine intake manifold is effective through a link 31 upon the latch 16 so as to break the connection between the pedal 4 and the shaft 19 when the engine is running. An electromagnet 39, 41 connected to the link 31 is effective when energized, to remove the latch 16 and is energized when a relay 53 is de-energized upon backfire of the engine. Relay 53 is controlled by normally closed contacts 64, 66 of a switch 55 which is operated from the engine intake manifold so that when a backfire occurs a piston 59 is raised and closes contacts 68 and 67. Contact 67 is on a bimetal strip 63 carrying contact 64 and contact 68 is grounded so that closure of contacts 68, 67 causes heating of the strip 63 so as to separate contacts 64, 66 to de-energize the relay 53. Reclosure takes place after a time lag. Contacts 64, 66 may be arranged. directly in the circuit of the electromagnet 39 which is then arranged so that it engages the latch 16 when energized. Specification 415,110 is referred to.

Title: Method and apparatus for rapid marking of articles
IPC: B05B15/04
Filed: 1974-03-22
Abstract: 1460488 Selective printing HOTCHKISS BRANDT MECANISATION 22 March 1974 [18 April 1973] 12950/74 Heading B6F In a method of rapidly applying marks on to articles by spraying with ink, the ink is centrifugally accelerated by rotation about an axis, and guided in a sweeping path towards the article to be marked. The ink-spraying assembly 4, Fig. 2 incorporates a disc-shaped rotor 15 rotating about axis 14a and comprising at least one guide duct 19 whose outlet orifice 19b is further from axis 14a than its inlet orifice 19a, ink being supplied to the inlet orifices 19a through axial duct 21 and chamber 16a. Coaxially mounted with rotor 15 are a plurality of flexible arms 23 corresponding in position with the guide ducts 19 and each provided at its end with a jet-deflecting paddle 22, also Fig. 4 (not shown). The paddles 22 interrupt the jet of ink from outlet orifice 19b, and the deflected ink is guided by cup 25 to a discharge orifice 9a, and return duct 9, Fig. 1 for recirculation. If, under the influence of electromagnet 30, paddle 22 on arm 23 is pulled into non-deflecting position 47, the ink jet from orifice 19b travels via orifice 26 in rotary cup 25 and sweeps the space surrounding rotor 15. By means of fixed mask 5, Fig. 1 and calibration slit 6, bars 40 can be marked on e.g. envelope 1 being carried on a conveyer 3. The operation of electromagnet 30 is such as to produce the required pattern of bars on the envelope 1. The marking installation can automatically be regulated for variation in the speed of articles, by use of synchronous electric motor 13 supplied by alternator 6, coupled to the conveyer 3.
