Title: Improvements in weighing scales and the like
IPC: G01G23/34
Filed: 1923-10-23
Abstract: 220,503. White, A. E., (Dayton Scale Co.). Oct. 23, 1923. Computing-apparatus. - An optical indicating device for use with weighing-scales having a number of adjacent movable number scales, for example, the surface markings of a computing drum, comprises a reading device including means for selectively illuminating any desired scale and for reflecting from the surface of the chart an image of the selected illuminated scale upon a reading screen. As applied to a computing weighing-scale, Fig. 3, the drum housing 10 is provided with guides 18, 23 along which a casing 25 may be slid by means of a handle 27. The front end of the casing carries a tapered tube 37 extending into a box 15 secured to the drum housing. The tube 37 terminates close to a ground glass screen 16. A price per pound scale 19 indicates the position of the casing 25. Within the casing is an electric lamp 30 from which the light is directed by a lens 32 and mirror 33 to the value scale on the computing drum 11. The salesman by looking through an aperture 40 and aligning two wires 41 may thus read off the money value of the goods. The light from the value scale thus illuminated is also reflected by a mirror 34 through a lens 35, and from a mirror 36 on to the screen 16 thus producing an enlarged image of the value reading visible to the customer at the front of the machine. Weight graduations are provided on the drum for direct observation through apertures at both sides of the machine. In a modification, Fig. 6, the drum has two sets of value graduations for each price per pound, and a single lamp 30 in conjunction with a system of lenses and mirrors projects the value images on to two screens 16, 16<a>. A pointer 29<a> indicates the price-per-pound setting on a strip 19<a> secured to the drum housing. In a further modification, two lamps, one for each screen, are employed instead of a single lamp.

Abstract: 1,126,559. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 12 June, 1967 [14 June, 1966], No. 26538/66. Heading H2J. The armature of a D.C. motor is supplied through series connected main P1 and auxiliary P2 rectifier bridges, the latter being controllable and of smaller capacity and is energized first. The field F is variable by unspecified means. P2, comprising thyristors, is energized first, at a late firing angle and with full field. The firing angle is advanced to maximum followed by field weakening. When the limit of this is reached the field is abruptly restored to maximum and P1 is energized after which P2 and the field is further regulated as desired. P1 can supply 65% of full power and P2 25%. P2 may be arranged to buck P1 when P1 is first switched in. As shown, P1 and P2 are supplied from separate transformers, but instead there may be one transformer with two secondary windings, with switches either in the A.C. or the D.C. side.
Patent GB-814530-A (GB)
Title: Improvements in or relating to methods of and means for wrapping block-shaped articles
IPC: B65B19/02
Filed: 1955-09-16
Abstract: 814,530. Wrapping-machines. MOLINS MACHINE CO. Ltd., and HALL, C. T. Sept. 13, 1954 [Sept. 16, 1955], No. 26589/55. Class 94(1). A method of wrapping a block-shaped article, e.g. a batch of cigarettes, comprises moving the article sideways, folding a piece of wrapping material about part of the article so as to enclose it, and subsequently moving the article lengthwise and folding a second piece of wrapping material about the remaining part of the article so as to enclose it and overlap the first piece. The resulting composite wrapper is shown in Fig. 6, the smaller portion being readily removable to expose the ends of the cigarettes. A machine for carrying out this method comprises a hopper 1 from the base 3 of which batches of cigarettes are withdrawn by a pusher and fed into successive compartments 4 of an intermittently-rotatable wheel 5. The batches are carried downwardly and ejected from the compartments on to a bed 6 by pushers on an endless chain which moves them lengthwise through converging guides 7 into successive open-ended pockets 9 of a chain conveyer which is moved intermittently over a bed 8. The batches are inserted only part-way into the pockets so that on movement of the conveyer their projecting portions successively engage wrappers W which have been fed downwardly and cut from a web. Each wrapper is then folded into U-form about its associated batch by guides 12, 13, Figs. 2 and 3, and the trailing portions of the U are folded upwardly and downwardly by folders 18 and 19 which are operated in succession by cams 21 and 22 on a shaft 35. The rear face of each batch is engaged by a spring-loaded member 14 pivoted at 15 to each pocket 9, this member being swung rearwardly to allow operation of the folders by the engagement of a roller 16 thereon with a finger 17 which is operated by a cam 20 on the shaft 35 so as to be lowered into the path of the roller and then retracted to allow the member 14 to spring back into engagement with the folds. The end portions of the wrapper are then tucked in by a stationary tucker 36 and a cam-operated tucker 37 and the resulting flaps are folded upwardly and downwardly by cam-operated folders 42, 43. The folds are retained by a stationary guide 50 as each pocket moves around the conveyer end sprocket to an ejection station E where one of a series of pushers P on an endless conveyer passes through a slot 52 in the pocket to eject the partially-wrapped batch and move it between guides 11 on a table 10, Fig, 1, into engagement with a second wrapper W2 which is subsequently folded in known manner by folders F. In a modification, not illustrated, the folding devices 12-43 are duplicated on the other side of the bed 8, each partially wrapped batch being pushed through the associated pocket 9 until its unwrapped end is exposed and a second wrapper, similar to the first, being applied and folded before the batch is ejected.

[Also in Division E1] Corrugated strip is continuously produced by passing it between a series of relatively moving, meshing, generally triangular bending tools which form corrugations each extending across the strip, the strip being additionally shaped by the impression of a desired transverse profile thereon. Co-operating bending tools 12, 16 are carried by chain links 10 of opposed endless chains, one of which is driven, the tools being so shaped as to give the strip a trough-shaped profile as well as forming the corrugations. The nodes of the corrugations may be additionally shaped to resist buckling and this may be effected after the corrugating by a press comprising upper and lower tool carried by pairs of cranks so as to match the velocity of the strip. The tools 12, 16 may be so shaped as to form corrugations, the legs of which are laterally angled relative to one another, Figs. 8- 14 (not shown). The tools may be shaped to corrugate a plurality of strips side by side, optionally with corrugations of different height and/or bend angle, Figs. 15 and 17 (not shown). To aid the tools 12, 16 to disengage the corrugated strip they may be moved apart at the exit by cam means, Figs. 18-19 (not shown). The tools may incorporate a cam-actuated punch at their apices to deform the strip. The corrugated strip is connected to upper and lower chord members by welding to form pylons, masts, joists or the like.

Title: Improvements in or relating to circuit arrangements in colour television receivers
IPC: H04N11/14
Filed: 1958-08-21
Abstract: 899,703. Colour television. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 21, 1958 [Aug. 24, 1957], No. 26912/58. Class 40(3). In a colour television receiver for use with a signal comprising a luminance component and a complex colour component conveyed by one or two sub-carriers and from which colour signals are derived with the aid of a matrix circuit, adjustment of the brightness levels of the individual colours for the purpose of obtaining a correct reproduction of white is effected with the aid of an auxiliary matrix circuit which has the same linear relationship as the relationship between the complex colour component and the composing colour components and responds to D.C. input voltages representative of desired brightness adjustments to produce output voltages which are added to the colour signal, either prior to or after detection of the sub-carrier or sub-carriers. The invention is illustrated, Fig. 1, as applied to a receiver using a N.T.S.C.-type signal in which the sub-carrier is detected synchronously at 5 and 6 to derive I and Q signals which, together with the luminance signal Y, are applied to a matrix circuit 16 to derive R, G and B colour componet signals. In accordance with the invention, an auxiliary matrix 11 receives input D.C. voltages r, g and b and derives output voltages X and Z which bear the same linear relationship to r, g and b as the I and Q signals bear to R, G and B. The voltages X and Z are combined with the I and Q signals in adders 9 and 10. Colour distortion of white is corrected by appropriate adjustment of voltages r, g and b, the matrix 11 causing D.C. voltages to appear with each of signals R, G and B of such polarity and amplitude that the desired shift in colour is effected by change of the relative brightness levels but without change of the total brightness. In a modification, Fig. 3 (not shown), voltages X and Z are modulated in quadrature on an oscillation at sub-carrier frequency and added to the received sub-carrier before detcctors 5 and 6. Detailed circuits for carrying out the invention in a receiver in which the synchronous detectors operate to produce colour difference signals, i.e. R-Y and B-Y. and the voltages X and Z are added after detection are described with reference to Figs. 4 and 5 (not shown). In Fig. 4, the auxiliary matrix forms a part of the main matrix and is included in the anode circuits of high-level synchronous detectors.
