Title: A retractable writing implement having multi-coloured ink containers
IPC: B43K24/16
Filed: 1959-04-09
Abstract: 867,258. Reservoir pens. NAGELE, B. April 9, 1959 [April 9, 1958], No. 11940/59. Class 146(3). In a retractable writing instrument having selectively advanceable ink containers 17 for different colours of ink, an insert 21 fixed in the barrel 1 guides a rotatable, slidable spindle 3 having a driving nose 24 and a return nose 35 spaced therefrom, the ink containers have extensions 19 with inwardly turned rear ends 22 whereby rotation of the spindle 3 may cause any one of the ends 22 to enter the space between the noses, the spindle carries a transverse latching bolt 36 to engage under a shoulder 45 of the insert 21 in the writing position, and the insert 21 carries a slidable stop ring 10 by which the latching bolt 36 is retracted when the spindle is moved beyond the writing position. The insert 21 is threaded at 47 for screwing into the barrel 1 and has a number of longitudinal slots 20 corresponding to the number of ink containers 17, the slots being extended through the threaded portion 47 in the form of external grooves. The extensions 19 slide in these grooves and the ends 22 thereof pass through the slots 20, to be retained, when the corresponding ink containers 17 are in the retracted position behind a locking ring 27 which is mounted in the insert so as to be rotatable but not displaceable axially. The spindle 3 is slidable in a nut 34 at the rear end of the insert 21 and in the ring 27 but is secured against rotation in relation to the latter by the engagement of a projection 31 on the ring 27 in a longii tudinal groove 30 in the spindle. The spindle is biased rearwards by a spring 14. The rear end of the spindle is fitted with a press-button 23 which projects from the rear end of the barrel. The locking ring 27 has a cut-out portion 29 through which the noses 24, 35 on the spindle 3 can slide and which by rotation of the press-button 23 can be brought into register with any of the ends 22 of the extensions 19, that end then lying between the noses 24, 35 of the spindle 3, Fig. 2: If the press-button 23 is then depressed the noses 24, 35 will carry the end 22 through the cutout 29 and will advance the corresponding ink container 17 until the laterally spring- urged latching bolt 36 on the spindle 3 engages under the shoulder 45 thus holding the ink container in the projected position, Fig. 1. Rotation of the spindle is now prevented by the partial projection of the noses 24, 35 into the appropriate slot 20. Further depression of the press-button 23 brings the tapered outer end of the bolt 36 into engagement with the tapered rear end of the stop ring 10 which has the effect of forcing the bolt inwards so that when pressure on the press-button 23 is released and the parts including the stop-ring 10 which is coupled to the spindle by the bolt 36 are carried rearwards by the spring 14 the bolt can,ride past the shoulder 45. The colour of ink container selected is determined by means of appropriately coloured dots such as 44 on the press-button.

Title: Apparatus for registering the work output of internal combustion engines
IPC: G01L3/24
Filed: 1948-05-03
Abstract: 652,316. Internal -- combustion engine indicators ; integrating-apparatus. SQUARED CO. May 3, 1948, No. 12017. Convention date, May 8, 1947. [Classes 106 (ii) and 106 (iv)] Apparatus for registering the work-output of internal-combustion engines comprises a counter actuated by means controlled jointly by the number of engine revolutions and an arm adjustably fixed to a member which bridges two capsules, one exposed internally to engine induction manifold pressure and externally to ambient air pressure, the other an aneroid capsule responsive to ambient pressure. A pawl 32, Fig. 2, is oscillated at a speed proportional to the speed of an aircraft engine, being driven from a tachometer shaft 39 through gearing and linkwork, and in each oscillation advances a ratchet-wheel 33 a number of teeth determined by the position of a masking sector 26, which is set through linkwork in accordance with the induction manifold pressure by means of a group of capsules 6 internally communicating with the manifold. Thus in a given time the ratchet 33 has an angular displacement determined by engine speed and engine manifold pressure and, being fixed to a shaft 24, acts through a crank 41 to drive a counter 44, Fig. 4, calibrated in horsepower-hours, to register the work output of the engine in the given time. Parts 28, 29 and 23, 26 are fixed together respectively by adjustable means and are rotatably mounted on the shaft 24. The capsules 6 are linked to a second set of capsules 11 by a floating bridge 12 with an arm 16 fixed thereto by a pivot 17 and yoke 18. A link 19 is pivoted to the arm 16 near a point thereon which remains stationary during changes of atmospheric pressure affecting the capsules 6, 11 so that the link 19 moves only in response to changes of manifold pressure. However, the work output will be affected by changes of atmospheric pressure and so the link 19 may be pivoted to the arm 16 at a point offset from the said stationary point so as to give a correct integration at a particular altitude. To obtain a printed record of the output, an ink ribbon 51 passes from a roll 53 to a roll 52 beneath type associated with the counter and upon depressing a handle a resilient stamp 57 is pressed down until a latch is released to allow the stamp to strike a card inserted below the ribbon against ribbon and type to imprint the registered output.

Title: Improvements in or relating to key board mechanism for telegraph apparatus
IPC: H04L17/06
Filed: 1931-04-23
Abstract: 375,923. Selective punching machines. CREED & CO., Ltd., Telegraph Works, Croydon.-(Teletype Corporation; 1400, Wrightwood Avenue, Chicago, U.S.A.) April 23, 1931, No. 12036. [Class 31 (ii).] A keyboard arrangement, for the perforation of a tape in accordance with the code combinations of a signal, employs signal keys associated with shift keys and locking means arranged to prevent the simultaneous operation of two or more signal keys, but to permit the simultaneous depression of a signal key and a shift key. The keyboard arrangement is similar to that of an ordirary typewriter, and the shift keys move solely a single additional or sixth selector bar, which is also moved by the depression of some of the signal keys, normally corresponding tc shift characters with a fiveunit system. All the key levers 11 engage one or more of the bars 25 for selective movement and additionally a universal bar 44, whilst the levers 11 corresponding to some of the characters also engage can. projections 28<1> on the sixth bar 251 to move it from the position in which it is normally held by a spring 29. The levers 11<1> of the shift and lock shift keys 17, 18 respectively, invariably engage a cam lug 281 on the bar 25, but are arranged opposite notches in the bars 25, and the universal bar 44 which may be operated by the simultaneous depression of a shift character key and the corresponding lever 11. Owing to the arrangement of the inclined cam lugs 28 on the bars 25, the simultaneous depression of two or more signal keys is pievented since the arrangement of the inclined faces on the bars 25 under each key lever will be different and for the depression of a second key there will always be at least one bar which would have to be moved in a direction opposite to that in which it has been moved by the depression of the first key. When the lock-shift key 18 is operated, the bar 11<1> is held in the depressed position by a pin 20 which engages with a notch in a pivoted member 19. The lock-shift is removed by actuating shift key 17 which, through a member 22, rotates the member 19 to release the lever 11<1>. For effecting the perforation of the tape, the code bars 25, 25<1> position auxiliary selector bars 48, carried on an anvil 51 formed as the armature of an electromagnet 55, with respect to punch rods 49. The universal bar is arranged to energize the electromagnet 55 and the tape is stepped forward by a ratchet wheel 58 actuated by a pawl 57 on the return stroke of the armature.

Title: Improvements in and relating to the manufacture of chocolate
IPC: A23G1/18
Filed: 1932-04-27
Abstract: 395,834. Tempering chocolate masses ; screw conveyers. SCHRAMM, O., LAUENSTEIN, O., LAUENSTEIN, W., 12, Georgiistrasse, Wernigerode, Harz, and EYERMANN, W. H., 8, Tauentzienstrasse, Magdeburg, both in Germany. April 27, 1932, No. 12080. Convention date, Nov, 6, 1931. Addition to 392,350. [Class 28 (i).] The process for tempering chocolate masses according to the parent Specification is modified in that the chocolate mass is cooled to somewhat below the operative temperature and is then reheated to the operative temperature in the end-piece of the extrusion conveyer solely by frictional heat of the mass in the shallow helical grooves of the conveyer worm, the required temperature of the mass in the end-piece being obtained by regulating the heat radiation of the end-piece, e.g. by heat insulation or by a jacket swept through by a liquid at a suitable temperature. For further increasing the frictional effect holes may be provided in the threads of the worm or the threads may in places be completely interrupted. The process may be carried out in the apparatus shown comprising a water-jacketed hopper 1 for the chocolate mass provided with stirring mechanism, and the water-jacketed conveyer which is cylindrical and is divided into three zones II, III, IV. The chocolate mass is cooled during its passage through the hopper 1 and zones II, III, the temperature of the water in the cooling jackets being regulated by thermostatic devices F1, F2, F3, and is heated by frictional heat in the end zone IV which is surrounded by a water jacket, the temperature of the water in this jacket being controlled by a thermostatic device F4. The thermostatic devices may comprise mercury containers 5 partly or completely surrounding the conveyer in the form of rings and preferably influenced directly by the chocolate mass. A return-flow pipe 4 may lead back from the discharge end of the conveyer to the hopper 1.

Abstract: 596,245. Swarf removal devices for phonograph recorders. BRITISH BROADCASTING CORPORATION, DAVIES, H., TERRY, P. E. A. R., and LLOYD, W. J. May 14, 1945, No. 12112. [Class 40 (ii)] A device on a phonograph recorder for removal of swarf during cutting of a record, consists of a suction-pipe 14, Fig. 1, directed near to the centre of the record and a blowing pipe 24 placed radially just outside the recording head 12, and attached to it, so that a jet of air is directed past the stylus point 13 towards the suction-pipe 14. The air-extracting pump 22, driven by a motor 21, may be used to supply air to the blowing pipe 24, and any excess air pressure may be used to pass a current of air through ancillary equipment, such as the amplifier housed in the cabinet 10, for cooling and cleaning. The function of the apparatus is to blow the swarf, which takes the form of a fine thread, from the stylus 13 to the suction jet 16 of the suction pipe 14, which may either be lowered about a point 15 to its operative position, as shown in Fig. 1, or raised to a position facilitating disc-changing, each position being maintained by a stop mechanism detailed in Fig. 2 (not shown). The air passes through the chamber 17 to a pipe 19 leading to the pump chamber 20. The swarf 31 falls to the bottom of the chamber 17, from whence it may be removed via a removable air-tight door 29. It is prevented from being drawn across to the pipe 19 by a cylindrical baffle 27 and a gauze air-filter 28.

A control valve unit for use with a hydraulically operated lifting and lowering device, comprises a rod 14, axially movable by a lever 15 and carrying a radially contractable stop ring 12 at one end, which is slidable in a piston 8, having two different diameter bores 9 and 10 separated by a frustro-conical step 11, a three position valve 2 controlling the flow of fluid to the lifting device, via connections 3, 4, 5 and 6, and a non-return valve 7 controlling flow through the connection 4. In operation, the connections 4 and 6 supply a working cylinder of the device, and with the unit positioned as shown in Fig. 1, they are connected via the valve 2 to low pressure, and the ring 12 abuts the step 11 to hold the valve 7 open so that the device can be moved by the load. If the valve 2 is set to supply the connection 3 with pressure fluid to lift the device the piston 8 is forced backwards, the ring 12 riding over the step 11, and the valve 7 is maintained open by fluidpressure. Upon switching the valve 2 to connect the connection 3 to a low-pressure source, valve 7 closes and the load carried by the device is held. When the connection 5 is supplied with pressure fluid to lower the device, the piston 8 is moved to open the valve 7, and allow fluid through the connection 4 to exhaust. If the rod 14 is retracted by movement of the lever 15, Fig. 4 (not shown), the piston 8 cannot hold the valve 7 open after lifting or lowering, and the device cannot be moved by the load.

Title: Improvements in the manufacture of cellulose ester filamentary materials
Inventor: GRADY DENNIS
IPC: D01F2/30
Filed: 1954-04-28
Abstract: An organic acid ester of cellulose having a pH below 6 or above 7.5 is treated so that the pH is brought within these limits, whereby the meltspinning properties of the ester are improved. The pH of a cellulose ester is defined as the pH acquired by pure water brought into intimate contact with the ester under specified conditions.  The pH of the ester may be adjusted by treatment with a solution of an acid of dissociation constant greater than 10-6, and preferably in the range 1 X 10-4-2 X 10-2, for example tartaric, citric or phosphoric acid, usually in 0.004-0.03 per cent concentration by weight based on the ester, for a period of 1-3 hours.  Preferably, however, the cellulose ester is treated with a buffer mixture of salts of a di-or poly-basic acid capable of maintaining a pH of 6.0-7.5, and especially 6.4-7.0, such mixtures being, for instance, buffer mixtures of phosphates, citrates and tartrates containing 0.01-0.05 per cent, preferably 0.01-0.03 per cent, of sodium based on the weight of ester, either in aqueous solution or in a solution containing a water-miscible organic liquid which has a swelling action on the ester, such as a lower monohydric alcohol. The ester which has been treated is then preferably drained and dried in a current of air at 125 DEG  C. before being melt spun.  The process is especially applicable to cellulose esters of saturated monocarboxylic acids with 2-4 carbon atoms, and particularly to cellulose triacetate having an acetyl value of 59-62.5 per cent. In a modification, cellulose esters having pH values initially within the prescribed range are treated with a buffer mixture as described above before they are melt-spun, although the buffer concentration then used is much lower and is in the range 0.005-0.01 per cent of sodium, based on the ester.  In the first Provisional Specification reference is made to the use, as stabilizers for cellulose triacetate in the manufacture of which sulphuric acid has been used as the catalyst, of mixtures of sodium phosphates, or other buffer mixtures, of pH 6-8, applied in an aqueous solution containing a volatile organic swelling agent, such as methanol.  Specifications 719,853, 719,860, 721,674, 726,900, 731,930, 748,772, 761,158 and 763,489 are referred to.

Title: Improvements in the production of glycol sulphite
IPC: C07D327/10
Filed: 1955-04-29
Abstract: Glycol sulphite is produced by causing ethylene oxide and sulphur dioxide to react on each other in the liquid phase at a temperature of 50 DEG  to 170 DEG  C., preferably 130-170 DEG  C., in the absence of catalysts.  The reactants are preferably used in equimolar amounts.  Pressures of 4 to 25 excess atmospheres are necessary to maintain the reactants in the liquid phase.  Gaseous sulphur dioxide may be passed into cooled liquid ethylene oxide whereupon an addition compound is formed which is then exposed to 50 DEG  to 170 DEG  C. in a pressure vessel.  In an example, ethylene oxide and sulphur dioxide are introduced in the liquid phase under pressure into a pressure coil at 140 DEG  C.  Premixing of ethylene oxide and sulphur dioxide heats the mixture to 50-70 DEG  C. before entry into the coil.  The product is pure glycol sulphite.
