Patent GB-223227-A (GB)
Abstract: 223,227. Bergmann, J. Oct. 9, 1023, [Convention date]. Adding and subtracting apparatus comprises numeral-bearing slides 1 having teeth 2, the upper teeth having red marks 3 in the bottoms of the gaps, and the figures of the numeral slides showing through windows 4 in a cover plate 7. Between the numeral slides and the cover plate are setting slides 5 having apertures 6 registering completely with the gaps and coloured portions of the teeth of the numeral slides, and each having two sets of figures 0 - - 9 theceon. Between the cover plate 7 and the base plate 23 at the upper and lower ends of the setting slides are two resetting bars 8 and 9 coupled by links 11 to handles 1.0, so that after the addition of each item the setting slides may be reset prior to a fresh operation. To add, say, 4 in the second denomination from the right a setting pin or stylus is inserted through the " 4 " hole of the setting slide 5 and the corresponding gap below in the teeth of the numeral slide 1 and the two slides are pulled downwards till the stylus abuts the lower edge 27 in the cover plate 7. With printing mechanism.-The setting slides 5 have upstanding teeth 12 meshing with teeth 13 of item wheels 14 which coact with a slide 15 carrying a platen 16 and a paper strip 17 fed from a roller 18 to a roller 19 bv a ratchet 20 on the latter and teeth on a slide 22 yieldingly mounted on the base plate 23. To effect printing, the platen is moved by hand towards the type wheels by means of a projection 25 on the slide 15. The Specification as open to inspection under Sect. 91 (3) (a) describes also the manner of mounting the numeral slides 1 and also the transfer mechanism. The numeral slides 1, Fig. 1 (Cancelled) are fixed to guide elements a moving in slots b of an intermediate plate c. At each end of the elements a are short lugs h and long lugs g, of which h correspond with slots d in the intermediate plate c, these lugs guiding the elements a on the edges of the plate c. These elements a have teeth i and also notches j engageable by springs m on the plate c. Transfer mechanism.-Short axles n, Fig. 1 (Cancelled) traverse the intermediate plate c and carry four-toothed wheels o and wheels p having a larger number of teeth engaging the teeth i of the guide elements a. The wheels o are operated by the setting stylus and through the wheels p perform the necessary transfer. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in means and methods of obtaining and transmitting information
IPC: H04Q9/00
Filed: 1963-06-05
Abstract: 1,082,951. Electric selective signalling. A. JÀ BAGGOTT. Sept. 7, 1964 [June 5, 1963], No. 22359/63. Heading G4H. A telemetering system for transmitting to a remote point signals representing, for example, the readings of all the meters in each of a number of blocks of flats comprises means for representing each reading by a D.C. amplitude, each on a separate channel, means for selecting one of the blocks of flats, means for scanning each channel in turn and converting the amplitude signals to duration signals for transmission to a central station. For each meter a potentiometer with ten steps, Fig. 7, produces ten reference amplitude signals. Each meter 1, Fig. 2, is connected to a repeater unit, e.g. a stepping motor, which operates the wipers of four selector switches representing four decimal digits. For each meter two of the outputs from the potentiometer are permanently connected at 3 to produce voltages representing the two address digits of the meter. The desired block of flats is selected by switch 7 to start the corresponding reed oscillator 6. Cascaded counters 10 and 12, Fig. 1, produce clock pulses from oscillator 6. Counter 13 produces distributed clock pulses and, for every ten input pulses, a pulse to cascaded counters 14 and 16. These also produce distributed clock pulses each on ten leads. A diode switching matrix 15 connecting the outputs of counters 14 and 16 energizes the potentiometer for each meter in turn for about 2 seconds. During this time the six output lines for the selected meter and a further line carrying a print control signal are scanned by the ten outputs from counter 13, leaving 3 spaces in the signal. The amplitude signals are switched in turn to an analogue-todigital converter 28 in which the input signal is compared with a rising step waveform from generator 11. The output of the converter is applied to a pulse width generator which produces a signal having a pulse width proportional to the amplitude of the input signal. The duration signals are transmitted in succession preceded by two digits from unit 17 indicating which block of flats is being monitored. At the receiver the duration signals open transistor gates to pass a number of pulses. These are counted to obtain a signal on an appropriate one of twelve leads to control a printer recording the addresses and the readings of all the meters in turn.

Title: Improvements in or relating to mold opening and transporting devices
IPC: B29D30/06
Filed: 1930-07-24
Abstract: 354,988. Mould-opening apparatus. FIRESTONE TYRE & RUBBER CO., Ltd., Great West Road, Brentford, Middlesex.- (Firestone Tire & Rubber Co.; 1292, S. Main Street, Akron, Ohio, U.S.A.) July 24, 1930, No. 22364. [Class 87 (ii).] The lid of a watch-case vulcanizing mould is raised by a chuck 42, the jaws of which are operated by a handle 43. The chuck is carried by toothed sectors 33 driven by spur and worm gear from a motor 36 furnished with an automatic brake 38. A second motor 30 rotates the chuck and sectors bodily about the vertical axis 26 by driving the pinion 28 through a slipping clutch 29, and thus transmitting motion to the fixed ring 27 on the sector-carrying frame. A third motor 21 fitted with a magnetic brake, is used to traverse the apparatus along the I-beams 11. Fixed racks under the beams are in gear with pinions driven by worm gearing from the motor shaft. The rear of the sector-carrying frame is fitted with two wheels 19 engaging the beams, while the front end is fitted with a pivoted arm 17 carrying two more wheels, the whole arrangement giving a 3-point suspension. The three motors are interconnected electrically and limit switches are provided so that (1) the apparatus cannot be rotated or traversed unless the sectors are in their raised or an intermediate position, (2) the sectors cannot be raised or lowered during traversing, (3) the traversing motor is started automatically and runs to the next mould only, when the sectors are raised to an intermediate position, and (4) limitation of all the movements by electric cut-outs occurs at the desired limit points.

Title: Improvements in pendulum weighing scales
IPC: G01G1/00
Filed: 1926-09-10
Abstract: 259,548. Dayton Scale Co., (Assignees of Gilbert, W. N.). Oct. 12, 1925, [Convention date]. Pendulum-weight apparatus.-In a weighing scale comprising indicating devices and a pair of oppositely-disposed pendulums, the pendulums are directly connected by crossed frictionless devices which constrain the pendulums to operate together in harmony even if the scale is tipped. The draw rod 20 from the platform lever system is coupled to a lever 10 fulcrumed on a bearing 14. One end of the lever is connected by a flexible tape 36 to a pendulum lever 44 carrying an arcuate arm 52. A similar pendulum lever 46 with an arcuate arm 54 is arranged' on the opposite side of the centre line of the scale, and the upper end of each arc is connected to the lower end of the opposite arc by a flexible tape so that the two pendulums are constrained to move together. Hanging from the arcuate surfaces is a loop of tape 64 passing round a roller 66 mounted in antifriction bearings in a vertical yoke 72 carrying the indicating rack 76. A link 86 connects the lower end of the yoke 72 with the lever 10 so as to guide the yoke in a vertical path. A dashpot 30 is connected to the lever 10. If the scale be moved out of level the consequent change of leverage of one pendulum will be neutralized by the change in the other pendulum.

Title: Improvements in or relating to tractors
IPC: F16H61/02
Filed: 1932-08-11
Abstract: 394,830. Band brakes. ETABLISSEMENTS E. BAUCHE, Le Chesnay, near Versailles, France. Aug. 11, 1932, No. 22552. Convention date, July 26. [Class 103 (i).] Each brake band 7 of an epicyclic gear is operated from a cam 16 on a shaft 15 which acts on a bell crank 12 which is pivoted at 11 to a lever 9, which it rotates in the direction of the arrow f about its fixed pivot 10 by means of a shockabsorbing spring 18. The lever 9 thus moves the end 8 of the brake-band in an anticlockwise direction, while the other end is moved in the opposite direction by a lever 24 pivoted at 25 and carrying a roller 26 engaging a cam 27 on the lever 9, the part 27a of which has its centre of curvature at 10 so that, when the gear is engaged, the lever 24, which is subjected to most of the moment, exerts no moment on the lever 9 and thus no force on the cam 16 ; the action of the cam is thus facilitated. The top of the cam is grooved at 16b to hold it in engaged position. The relative position of the levers 9, 12 is adjustable by a bolt 22 passed loosely through a spindle 28 on the ]ever 12 and screwed into a spindle 29 on the lever 9 and held by a lock-nut 30. The compression of the spring 18 is adjusted by means of a nut 32 and lock-nut 20 on the rod 22. The cam shaft 15 may be rotated by a sprocket 17 and chain 34, which is tensioned by a pinion 35 mounted on a pivoted arm.

Abstract: 1,052,355. Brightening polyester fibres. J. R. GEIGY A.G. May 28, 1965 [May 29, 1964], No. 22782/65. Heading D1P. Fibres made from polymeric esters of terephthalic acid are optically brightened by impregnating them with an aqueous suspension of a mixture of optical brighteners containing no acid salt-forming groups and having a particle size less than 10Á and comprising a stilbene compound of the formula and at least one compound which is a derivative of coumarin, benzoxazole or napthalic acid imide, has an affinity to polyesters, forms colourless, blue fluorescent solutions and is free from stilbene groups, and then heating the impregnated fibres to a temperature of 180‹- 220‹C. The brighteners containing a coumarin ring may be derivatives of 3-phenyl-7-aminocoumarin preferably 3-phenyl coumarin compounds substituted in the 7-position by a 3- methyl-pyrazolyl-(l), naphtho-(1', 2' : 4, 5)- triazolyl-(2) or 4-chloro-6-diethylamino-1, 3, 5-triazinyl-(2) radicals suitable benzoxazoles are bis-benzoxazolyl-(2')ethylenes and -2, 5- thiophenes, and suitable naphthalic acid imides, are 4-alkoxy-naphthalic acid-N-methylimide and 4-acetamino naphthalic acid-N- butyl-imide. The particle size of the brighteners may be 1-5Á or less and may be present in a concentration of 0.3-5g per litre. The fine degree of distribution of the brighteners may be obtained by milling with sand in the presence of water and a dispersing agent, e.g. a condensation product of naphthalene sulphonic acid and formaldehyde, which may be present in an amount of 1/30th to 1/10th of the total weight of the mixture of brighteners. The aqueous suspension of the brighteners may also contain emulsifying agents, e.g. fatty alcohol polyglycol ethers such as stearyl alcohol polyglycol ethers having 8-10 ethyleneoxy groups, protective colloids, e.g. high polymeric polyacrylates or polyacrylamides and thickeners, e.g alginates, carboxymethyl cellulose and methyl cellulose, After impregnation the fibres may be squeezed out to a liquor content of 40-100% by weight, optionally dried and then heated. Fabrics comprising fibres of polymeric esters of terephthalic acid and cotton fibres may be brightened with an aqueous suspension which also contains a brightening agent for cotton, e.g. or may subsequently be treated with the brightener for cotton. The mixed fibre fabrics may be bleached with sodium chlorite or hydrogen peroxide prior to treatment with the brighteners or the brightener for cotton may subsequently be applied together with a hydrogen peroxide solution containing sodium silicate and sodium hydroxide.

Title: Improvements in and relating to the production of benzol from distillation gas
IPC: C10K1/18
Filed: 1932-08-15
Abstract: 405,992. Recovering benzol from gases. POLLAK, J. E., 20, Holborn, London.- (Benzola Ges. ; 20, Breite Strasse, Oberhausen, Germany.) Aug. 15, 1932, No. 22892. [Class 55 (ii).] In a process of recovering benzol from distillation gases by washing with oil, the yield is increased by preventing the accumulation in the wash oil of substances, such as phenol or naphthalene, which interfere with the absorption and liberation of the benzol by the oil. This is done by subjecting the gas prior to washing with oil to the action of water in relatively large quantities, or by subjecting the wash oil freed from benzol by steam distillation, or the residue from the re-distillation of the raw benzol, after separation of naphthalene by cooling, to indirect distillation, the distillate so obtained being cooled to separate naphthalene, steam distilled and the product re-introduced as wash oil into the process. These alternative methods may be used together. The gas after treatment with water may be led through one or more towers in which a reduction of the speed of the gas stream causes a separation of the naphthalene. The above described processes may be associated with the method of fuel distillation described in Specification 405,996.

Abstract: 1,213,356. Automatic flushing systems. AMERICAN STANDARD Inc. May 15, 1968 [May 18, 1967], No. 22977/68. Heading G1N. [Also in Division H3] A proximity operated timing circuit suitable for use in a urinal flushing system comprises a capacitor which is discharged when a body is detected and recharged when it departs and a transistor coupled to the capacitor so as to become conductive and operate on output circuit for a predetermined period after a delay initiated by the departure. When a body is sensed by a capacitive proximity detector 42-45 to have been present for a given period a relay contact 39 disconnects an A.C. supply 11 and operates a lamp 31. A reservoir capacitor 15 discharges as do capacitors 16 and 17. When the body departs the relay reconnects power to the circuit causing capacitor 15 to quickly recharge. Capacitors 16 and 17 commence to recharge, 17 more slowly than 16 and the charge current rises after about 1 second to a value sufficient to cause transistor 13 to operate a relay 35 and thus actuate the flusher, after a further period the charging current falls to a value insufficient to maintain the relay and flushing ceases. During flushing a voltage doubler rectifier 24, 25, 26 provides a reverse bias for the transistor which is variable to vary the flushing period and decays slowly to prevent false operation.
