Title: Accumulator for calculating accounting machines and the like
Inventor: MARZIO EMILIO DI
Filed: 1956-07-25
Abstract: 836,818. Calculating-apparatus. FABBRICA ITALIANA MACCHINE AZIENDALI. July 25, 1956, No. 23001/56. Class 106 (1). Transfer mechanism.. The totalizer wheels 2, Figs. 2, 3, are carried by individual plates 1 which are displaceable on transverse comb supports 5, 6 and 7 in order to roll the wheels along their actuating racks 20 for the purpose of effecting transfers. The plates are actuated by springs 101, but normally are locked by the engagement of latches 4 with lugs 105 thereon. At transfer, a tooth 100 on the lower wheel rocks a lever 3 which depresses the latch 4 to release the plate 1, carrying the higher order wheel, for transfer movement by its spring 101. A blade 29 on a shaft 28 restores displaced plates 1 early in the ensuing machine cycle. Totalizer engagement for addition and totaltaking. The totalizer is rockable as a unit about axis 18 by oscillation of a shaft 17 for moving the wheels 2 into and out of engagement with their actuators 20. Toggle links 14 and 16 connect the totalizer frame 11 with the shaft 17 whilst an arm 31 on the shaft is connected to a link 32 carrying a stud 33 which, under the action of a spring 32<SP>1</SP>, bears against a step either of an add sector 34 or a total-taking sector 45. These sectors are rocked in appropriate cyclic timing by respective followers 40 and 51 of cams 43 and 54 on a main shaft. Normally, the stud 33 engages the add sector 34, so that the totalizer is disengaged at the commencement of the cycle and re-engaged as the racks 20 restore. For total-taking, a solenoid 44<SP>1</SP> is energized and raises the link 32 to engage the stud 33 with the sector 45, so that the totalizer remains engaged during forward movement of the racks and is then disengaged. A second solenoid 651 also is energized, during total-taking, and engages an arm 63 on a lever 60 with a stud 65 on the follower 51. The lever 60 is now rocked cyclically and, through a link 58, rocks a bell-crank 57 carrying a rod 27 which bears. upon the tails of the transfer latches to position them for arresting the totalizer wheels in zero position.

Title: Improvements in the production of ethylidene acetone
Inventor: DALGLEISH ALEXANDER
Filed: 1953-08-21
Abstract: Ethylidene acetone is prepared by condensing acetaldehyde with acetone under aqueous conditions in the presence of an alkali-metal hydroxide catalyst at a temperature between 40 DEG  and 60 DEG  C., the alkali-metal hydroxide content of the reaction mixture being maintained at 0.005 to 0.05 per cent by weight based on the acetone plus the water, and subjecting the resulting hydroacetyl acetone to acid-catalysed dehydration.  The condensation is preferably effected by heating a mixture of acetone, water and alkali-metal hydroxide to about 50-55 DEG  C. and running in the acetaldehyde below the surface of the mixture over a period, say 1 1/2 hours, in the presence of a nitrogen atmosphere, using acetone : acetaldehyde molar ratios of between 5 : 1 and 10 : 1 and an acetone : water volume ratio of about 2 : 1, additional alkali being added if necessary.  The product is then neutralized, e.g. with oxalic acid, the acid catalyst, e.g. sulphuric or phosphoric acid added and the mixture distilled whereby ethylidene acetone and a minor amount of mesityl oxide are obtained. Examples are given.

Title: Improvements in or relating to high frequency oscillation generators
IPC: H01J25/52
Filed: 1936-08-21
Abstract: 465,650. Magnetrons; valve generating circuits; electric resonant units. LORENZ AKT.-GES., C. Aug. 21, 1936, No. 23067. Convention date. Aug. 24, 1935. [Classes 39 (i), 40 (iii), and 40 (v)] When a split-anode magnetron is used for generating short waves, it is known that the oscillations disappear when the magnetic field is so reduced that the electronic rotational frequency (which is directly proportional to the field strength) approaches the working frequency. The invention consists in reducing the field strength still further, when it is found that, providing the attenuation of the oscillation circuit is sufficiently low, oscillations are again set up. To maintain the optimum condition for oscillation, the anode voltage is reduced as the field strength is reduced, according to a formula given in the Specification. Attenuation is reduced by attaching to the anode sections 2 metallic sheets 8 which extend parallel to each other outside the envelope 1 to form a Lecher pair with shortcircuiting bridge 9. The sheets 8 may be plated with coatings of high conductivity, and may be fitted with cooling ribs. Radiation may be reduced by enclosing the tube 1 and conductors 8 in a metal casing, which may be slotted to allow cooling air to be drawn therethrough. The Specification as open to inspection under Sect. 91 states that the anode may comprise more than two parts, e.g. four. This does not appear in the Specification as accepted.

Abstract: 676,174. Printing on curved surfaces. NATIONAL CASH REGISTER CO. Sept. 25, 1950 [Sept. 28, 1949], No. 23434/50. Class 100 (ii). A device for printing on a rollable article, such as a paper roll 31, comprises an inclined shoot formed by a floor 20 and side-walls 21, 22 which guide the article as it rolls, as by gravity, across a resilient micro-porous printing plate 27 saturated with ink, having relief characters 29 and secured in an aperture in the floor 20 by a base plate and shim plates. The printing plate tends to shrink when inked, so that part of the background body as well as the characters must be set above the floor level, and raised lines 30 are provided to prevent inking of the article by the background surface. For spherical articles, the lines 30 would be in the mid-line portion of the plate. For printing on two zones of a spherical article simultaneously, a V-shaped chute may be used, having a printing plate in each sidewall. Specifications 582,474 and 608,998 are referred to.
Patent GB-1585583-A (GB)
Title: Container for hot consolidating powder
IPC: C04B35/645
Filed: 1977-06-02
Abstract: In the process a hot-press mould is filled with powder of a metallic or non-metallic composition for the production of a sintered body and is hermetically sealed. The hot-press mould and the powder are heated to a temperature at which the hot-press moulding material flows in a plastic manner and the powder fuses by sintering. Then an external pressure is exerted on the entire outer surface of the hot-press mould in order to exert a hydrostatic pressure on the powder in the mould cavity and to compact said powder to form a sintered body. The volume of the mould cavity must not be larger than the total volume of the hot-press moulding material, in order to form around the mould cavity walls of such thickness that the outer surface of the walls does not closely follow the contour of the mould cavity. A high precision of the press moulding is thus obtained and the finishing is less complicated than in sintered bodies produced by known processes.   <IMAGE>

Title: Improvements in the production of conversion products of rubber
IPC: C08L9/00
Filed: 1928-08-17
Abstract: 323,012. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Aug. 17, 1928. Yarns and threads; bobbins.-Yarns and threads and coatings for bobbins are formed from butadiene polymerization products. Non-distillable polymerization products of butadiene or of its substitution products in which the 1 or 1, 4 positions have been substituted with hydrocarbon radicals, are heated without sulphur to temperatures between 100‹ and 500‹ C. until hard products showing practically no extensibility are formed. Solvents, indiarubber, polymerization products of other diolefines, fillers, colours and plasticizers, for instance aryl phosphates, petroleum jelly, waxes and oils of high boiling point, may be added to the butadiene polymerization products before the heat treatment. In making silk-like threads the butadiene products are dissolved in a solvent having a boiling point below the temperature of heating, and fine jets of this solution are heated. In an example, a 30 per cent solution in cyclohexane of a polymerization product prepared from butadiene with the aid of sodium is extruded through spinning nozzles into a vertically arranged pipe, about 8 metres in length, heated from the outside to temperatures rising from about 100‹ C. at the top to 400‹ C. or more at the bottom. The atmosphere in the pipe is kept poor in oxygen by introducing an inert gas or vapour. The dry, hard threads are reeled on to bobbins at the bottom. The threads mav contain or be treated with fire-proofing agents such as tungstates or phospho-tungstates and may be made into yarns and fabrics. A metal bobbin, such as is employed in the manufacture of artificial silk, may be coated by dipping it several times into a 10 per cent solution in benzene of a polymerization product obtained from butadiene by the aid of sodium in the presence of butylene, and heating for some hours to from 100‹ to 150‹ C. Drying agents, such as linoleates or naphthenates of cobalt, manganese, or other metals. may be used for shortening the heat treatment. Other examples are described including the use of a product obtained by the extended heating of butadiene to about 70‹ C. in the presence of 20 per cent of its weight of a 3 per cent aqueous solution of hydrogen peroxide, and the use of a polymerization product obtained from 1-methylbutadiene with the aid of 0.5 per cent of its weight of aluminium chloride.

Title: Improvements in or relating to the control of illuminants
Inventor: HUNT ROBERT WILLIAM GAINER
IPC: G03B27/72
Filed: 1958-07-25
Abstract: 886,557. Colour filters for colour measurement or photography. KODAK Ltd. July 17, 1959 [July 25, 1958], No. 23969/58. Classes 97(1) and 98(2). A method of controlling illuminants for use in colour measurements or colour reproduction comprises the steps of introducing into the light beam to a varying extent a coloured filter having a greater transmission in one region of the spectrum and a lesser transmission in another region of the spectrum and keeping constant the total absorption of light in the region of said greater transmission by maintaining in the part of the light beam not intercepted by the coloured filter, a correcting light filter having substantially the same transmission in the region where the said coloured filter has a greater transmission and having a transmission greater than that of the coloured filter in the region where the said coloured filter has its lesser transmission. As shown a coloured filter 1 is cemented to a correcting filter 2 so as to be movable across a light beam from a source 3 before entry into an integrating box 4. For instance, the filter 1 may be a cyan filter and the filter 2 may be a reddish filter having a greater transmission in the red than the cyan filter, but transmission in the blue and green which is substantially the same as that of the cyan filter. In this way, movement of the two filters across the light path varies the red component without alteration of the green and blue components of the light from the source 3. In a modification the two filters are each in the form of superimposed coloured wedges.
