Title: Improvements in or relating to the marking of shoe parts
IPC: A43D95/14
Filed: 1950-10-07
Abstract: 699,299. Applications of luminescence. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HUSBANDS, T. G. Oct. 8, 1951 [Oct. 7, 1950], No. 24524/50. Class 39(i) A marking which will fluoresce when irradiated by radiation of a frequency higher than that of visible light, e.g. ultra violet light but which is not readily visible in normal daylight or artificial light, is made on a shoe part to assist a shoe-making operation such as stitching, punching, positioning one upper part relatively to another or the like; and the operation is carried out while the marking is fluorescing. Removal of marks imperfectly covered in the operation with possible damage to the shoe part is thus unnecessary. The marking may be made by a fluorescent ink i.e. a solution of a fluorescent material or a liquid having fluorescent material in suspension in it, or the marking may be provided by forming a fluorescent material in situ by chemical reaction.

Title: Method of removing material from the surface of bodies
IPC: B44B3/00
Filed: 1959-07-17
Abstract: 896,804. Engraving. TECHNIK & HANDELS A.G. July 17, 1959 [July 24, 1958], No. 24678/59. Class 100(2) Material is removed from the surface of bodies, e.g. of metal, in a single brief operation by supporting the body or a rigid support, securing it against horizontal displacement so that it is free to perform vertical rising movements, forcing a flat die with rib-type projections on its operative face against the surface of the body, and causing the body to vibrate in a substantially vertical movement, so that material is removed by a cutting operation. A watch part 10 to be provided with miniature lettering is placed on a support 11 and secured against horizontal displacement by stops 12, 13, 14. A die 15 having on its plate 16 raised lettering formed in ribs of triangular cross-section with an apex angle of 40 to 70 degrees is brought into contact with the part 10 and vibrated vertically at ultrasonic frequency. causing vertical vibrations of the part 10. If the part 10 is rigid, the stops leave a slight clearance to allow vertical movement as a whole. Otherwise, the part is clamped and the central part vibrates. The ribs may be formed in the support, while the upper die is replaced by a flat plunger. Cutting may be facilitated by a liquid jet containing diamond dust. The stops may be replaced by a continuous stop rim, or the part 10 may be held in a recess in the support 11.

Abstract: The invention comprises N,N1-tetra-acetic-acids of formula <FORM:0695346/IV (b)/1> where n is an integer of 0-5 and X is O or S. They may be made from o ,o 1-diamino-ethylene mono- or poly-ethers, or from the corresponding thio-ethers by reacting 1 mol. of ether with at least 4 mols. of a substituted acetic acid or its salts which is or are reactive in the a -position, e.g. mono-chloro and -bromo-acetic acids.  Instead of the free acid substituted derivatives thereof which are reactive in the a -position and which can be converted to the free carboxyl group may be used, e.g., esters, nitriles and formaldehyde cyanhydrin. Diamino-ethylenes specified are di-(b -aminoethyl)-ether, -thioether and -glycol-ether, o ,o 1-diamino-tetra-ethylene tri - ether, o ,o 1 - diamino - penta - ethylene - tetra-ether and o ,o 1-diamino-tetra-ethylene-dioxido-thioether.  The alkali metal salts are ion-sequestering agents.  In examples: (1) chloracetic acid is reacted with b ,b 1-diamino-diethyl ether in alkali lye to give b ,b 1-diamino-diethyl ether-N,N1-tetra-acetic acid on acidification, or the ether may be reacted with chloro-or bromo-acetic acid ethyl ester in an organic solvent to yield the acid on saponification; (2) ethylene glycol - bis - b  - amino - ethyl ether N,N1-tetra-acetic acid is made as in (1); (3) diethylene glycol-bis-b -aminoethyl ether is reacted with sodium chloracetate in alkali solution to give the sodium salt of the substituted acetic acid; (4) ethylene glycol-bis-b -aminoethyl ether-N,N1 - tetra - acetonitrile, formaldehyde and hydrocyanic acid are heated with alkali lye and the tetra-acetic acid separated on acid treatment, or the corresponding nitrile of b ,b 1-diaminodiethyl ether may be reacted to give the corresponding acid on saponification; (5) triethylene glycol-bis-b -aminoethyl ether is reacted with sodium chloracetate in alkali lye to give the desired tetra-acetic acid on acidification; and (6) b ,b 1-diaminodiethyl sulphide is reacted with sodium chloracetate in alkali lye to give b ,b 1-diamino-diethyl sulphide-N,N1-tetra-acetic acid on acidification.  The product of example (2) is evaluated by electrometric titration with N/10 NaOH in the presence of calcium chloride, that of (3) as the sodium salt by titration with 0.5 molar calcium chloride in the presence of ammonium oxalate and that of (5) as the sodium salt by electrometric titration in the presence of calcium chloride.  The starting ether of (3) is made from o ,o 1-dichlorotetraethylene glycol ether according to Gabriel's method.

Title: Printing preventing device for predisposing the justification of the right margin in a typewriter
IPC: B41J19/64
Filed: 1966-06-03
Abstract: 1,128,784. Typewriters. ING. C. OLIVETTI & C., S.p.A. 3 June, 1966 [9 June, 1965], No. 24851/66. Heading B6F. A power-operated variable-spacing typewriter in which type bars 7, Fig. 1, are actuated by interposers 3 which are rocked by a universal bar 14 when engaged by lugs 13 following depression of keys and actuation of clutch controlled cam 18 is provided with a type bar impression disabling device which prevents impact of type bars 7 but permits letter spacing by cam-operated escapement 171, 172 to type a trial line for subsequent justification of the line. Ribbon feed and vibration is also disabled. To type the trial line for subsequent justification the carriage is first brought to the righthand margin and an indexing member 21 is set to align its mark 24 (Fig. 3) with a mark 28 on a card holder 25. Carriage is then brought to beginning of line which is typed in a normal manner until carriage reaches the aligned marks 24, 28 when a lever 29, Fig. 1, is rocked anticlockwise to rock a lever 84 against the type guide 27 whereupon the left-hand edge of a lug 86 on the lever 84 is aligned with the right-hand edge of the last character typed. Rocking of lever 29 pulls forwardly a link 41, Fig. 2, which on the one hand rocks a bell-crank 63 to obturate with its free end 66 the ribbon vibrating lever 68 and on the other hand rocks a bell-crank 42 which aligns projection 51 on lever 47 with pin 52 on the universal bar 14. Simultaneously a link 33 rocks a bell-crank 36 to lock the lever 29 in its rocked position and also to rock a lever 77 whose lug 76 arrests and disables bail 72 which actuates the ink ribbon vibrator operating link 70 by intercepting lug 74 when the bail has been subsequently rocked anti-clockwise. Following depression of a type key and engagement of lug 13 with the universal bar 14, the latter is rocked by a spring 19 when the universal bar 14 follows the contour of cam 18, however, the spring action is slowed down by the lever 47, which is engaged with the universal bar 14 through projection 51 and which follows the contour of cam 58 through its associated cam follower 49, whereby the type bar 7 is not imparted the jerk necessary for impression but the cam 171 and follower 172 effect the variable letter spacing associated with the depressed type key. The other keys are depressed until the line is completed whereby the marks 24, 28 indicate the difference which if negative is compensated in subsequent re-typing of the line with the lever 29 restored by operation of an auxiliary space bar associated with the variable spacing typewriter to advance the carriage through three instead of two unit spacings.

Title: An improved method and means for comparing the densities of two fluids
Inventor: MARTIN ARCHER JOHN PORTER
IPC: G01N9/32
Filed: 1953-09-08
Abstract: 788,392. Comparing the densities of fluids. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 20, 1954 [Sept. 8, 1953], No. 24864/53. Class 97(3) An apparatus for comparing the densities of two fluids comprises an enclosure having an inlet and two vertically displaced outlets leading to flow resistances at least one of which is adjustable, a passage connected to the enclosure adjacent the two outlets and having therein a differential pressure or flow indicating device, and a second inlet connected to the passage on each side of the indicating device and having flow resistances, one of which is adjustable, in each of these connections. In the apparatus shown, the enclosure comprises vertical limbs 1, 2 with an inlet 10 and two outlets 12, 13 leading via flow resistances R3, R4 to a common outlet 15. The meter M is connected to outlets 12, 13 by parts of the passage 8, 9 and the second inlet 16 is connected through flow resistances R6, R7 to either side 17, 18 of the meter M. The inlet 16 is first plugged and a reference gas admitted through inlet 10 and out through outlet 15. The flow resistances R3, R4, which consist of rods adjustable in constricted parts of the limbs, are adjusted so that no pressure difference exists between the points 17, 18, which is shown by zero reading of the flow-meter or pressure gauge M. The reference gas is then also admitted through inlet 16 and resistances R6, R7 are adjusted so that again no flow is recorded in instrument M. The gas under test is then admitted to inlet 10 in place of the reference gas, and if its density is different from that of the reference gas a difference in pressure will be set up between points 17 and 18, and this will be recorded by instrument M. During test the gases are admitted at constant ratio through inlets 10 and 16 and each divide into two equal streams. The gases meet at junctions 12, 13 and pass cut together at 15. Specification 767,569 [Group XXIX] is referred to.

Abstract: 221,097. Gallimore, J. Oct. 6, 1923. Interconnecting guard with starting-gear. - In reversible dough-rolling machines, means are provided whereby the rollers can be started only when a guard member, movable endwise above the rollers into protective positions at the front and rear thereof, is in the protective position on the intake side, whence it cannot be displaced while the rollers are in action. The guard C, comprising a top 2, side shields 3, and preferably bars 6, is mounted for endwise movement above the rollers A and table B, the safety position being that in which the bars 6 are remote from the rollers. The guard may be pivoted on a moving or stationary axis, as that of a roller, or an axis at or below the level of the table, or it may be guided in a curved or straight path as by rods 4 running between sheaves 5. As shown in Figs. 1 and 2, the machine is driven by open and crossed belts, either of which can be moved from its loose pulley D' to a fast pulley D by the appropriate striker rod 15, 16. These rods are moved by a cam groove E<2> in a rocking member operated by hand levers E or by electric or other power, the rocking member actuating also through a toothed quadrant 9 and bevel gears 10, 12, 13 a shaft 14 having pinions 8 engaging racks 7 to traverse the guard. The groove E<2> is so shaped that the guard is moved to the safety position before a belt is shifted to start the machine in the appropriate direction, the wheels 12, 13 having mutilated portions co-operating during belt-shifting to lock the guard. The Provisional Specification refers to a form having a single rack only. Fig. 3 shows a modification in which the guard S is directly hand-actuated, one side shield 3 or other part moving with it having staggered holes 19 engageable when the guard is in a protective position by an appropriate plunger 18 slidden by the reversing-handle E<1>. This handle turns on a vertical spindle to actuate a single belt-striker rod 17. the machine being driven by a single belt and two fast pulleys, one of which drives through a reversing-train. The belt cannot be moved from the loose pulley unless one of the holes 19 is opposite its proper plunger 18, which locks the guard on the machine being started. The guard may be in two or more parts having connected end portions.

IPC: A61H31/02
Filed: 1936-09-12
Abstract: 487,395. Breathing and blood-circulation promoting apparatus. KOLB, F. Sept. 12, 1936, No. 24911. Void. Convention date, Sept. 12, 1935. [Class 81 (ii)] A patient is placed within a chamber, Fig. 12, and fitted with a face mask 63 connected, via a reservoir 60, to the pressure side of an air pump, the interior of the chamber being connected to the suction side, so that the pressure in the patient's lungs is never less than that of the air in the chamber. Alternation of the lung and chamber pressures, with any desired phase displacement between the two alternations is effected by an attendant in the chamber, who controls the amount of air escaping or entering the pumping circuit from the air outside the chamber. Manometers are provided in the chamber so that the various pressures may be observed. Preferably, the pressures are so controlled that when the pressure on the lungs reaches a minimum and commences to rise, the pressure on the body reaches a maximum and begins to fall. A pressure bag 91 may be fastened round the thorax and any desired pressure maintained therein by means of the hand pump 94 or the foot pump 95, taps 99 and 100 controlling the increase and decrease of the pressure. The venous circulation in the extremities may be closed by the application of pressure to sleeves 101 round the upper parts of the limbs. The chamber is made of dished plates assembled on a framework, and the joints between the various plates may be sealed by rubber gaskets 5, and tension members 6, 8, 9, Fig. 9.
Patent GB-249937-A (GB)
Abstract: 249,937. Wade, F. R., and Watson, A. V. Jan. 6, 1925. Postmarking, stampcancelling, and franking machines; handstamps ; printing-surfaces. - Relates to apparatus for franking or cancelling letters &c. wherein the printing- member is formed in two parts slidably connected together, one part printing a portion of the complete impression before the other part prints and apparatus for registering the impressions being operated through the relative movement of the two slides. One of the slides, for instance a slide f arranged in a casing a, is provided with a fixed die g and a complementary movable die h, the latter being depressed to complete the impression partly formed by the die g by the movement of a second slide k towards the slide f. Fig. 2 shows the device in the form of a hand stamp; alternatively, it may be connected to a heavy base as shown in Fig. 8. The slides are connected together by a pin-and-slot arrangement and are normally separated by a spring i. In use, a knob o is depressed, the two slides move together as one until the die g meets the letter when the second slide k moves relatively to the first, strikes against a stem h<2> on the die h and completes the impression. This relative movement is utilized to advance a counter r of usual construction mounted in the slide k, a pawl p carried by the slide f being arranged to engage a ratchet wheel q on the counter shaft. In the position of rest the die h is retained level with the die g for inking purposes but is released when the slide f descends and is then raised by a spring t. The die g carries dating-wheels y retained in a set position by a spring plate having a series of fingers one bearing on each wheel. The numeral wheels of the counter r are visible through a window arranged in a door providing access for resetting purposes, the door being locked or, alternatively, sealed by a lead rivet 20. Limit locking arrangements. This is of known kind comprising a bolt 3 arranged below the counter r and provided with a series of recesses in which are mounted spring-pressed plungers 5 which normally hold up pins 7 slidable in holes in the slide k. These pins are acted on by cams 8 on the counter wheels such that, at zeroization, the plungers 5 are depressed into line to release the bolt 3, which is thereupon moved by a spring 2 into a hole in the slide f thus locking the slides against relative movement and preventing actuation of the counter. Inking-apparatus.-The dies g, h are inked by a pad v mounted on a pivoted arm and spring- pressed upwardly to bear against the dies in the position of rest. On the descent of the dies the pad is pushed to one side. Platen machines.-In the construction shown in Fig. 8, the casing a is mounted on parallel links 14, 15 connected to an upright 12 pivoted to a base 13, a gauge 17 being provided for positioning the letters.
