Title: Automatic feeding mechanism for feeding lines of loose metal type to automatic metal type distributing apparatus
IPC: B41B3/04
Filed: 1924-11-07
Abstract: 246,925. Atkinson, T., and Day, H. C. Nov. 7, 1924. Galleys and galley-mechanism for type-distributing machines.-Means for feeding successive lines of type from a column or page to distributing-machines, such as that described in Specification 190,818, comprises a galley or table 1, Figs. 1 and 2, pivoted at one end 2, and supporting an endless band 4, Fig. 17, by which the lines of type are advanced into position to be ted into a line-receiving channel. The galley or table is of skeleton form, and carries rollers 3 for supporting the endless band, which slides over a platform 5. The galley is provided with a fixed guide-rail 6 and an adjustable spring-pressed guide-rail 7. Diagonal rollers 10, 10<a> serve to break up the type as it is fed forwards. The endless band has slots in its edges, and is advanced by teeth on the forward roller 3, which is driven by ratchet-mechanism from a cam, a spring being interposed to allow for the varying size of the type. The lines are pushed over a dead-plate 11, Fig. 17, having a knife-edge 12 directed towards the band. The end line is lifted by a slicer 20a, which is operated by a rod 23, Fig. 1, and a cam on the cam-shaft 20, the forward end of the galley being simultaneously lowered by a second cam. The lifted line is pushed into the line-receiving channel by a pusher 13, Fig. 8, which is operated through a lever 17 by a weight 19, when released by a cam. Another cam then puts the cam-shaft out of action. When distribution of the line is completed, and the pusher 13 has reached the end of its stroke, the cam-shaft is re-started by a rod 18 connected to the lever 17. The pusher is thereupon retracted by its cam, which acts through the rod 18. Specifications 15470/86 and 24624/98 also are referred to.

Filed: 1953-09-28
Abstract: 743,377. Rotary printing-machines. VEB DRUCKMASCHINENWERK VICTORIA VVB POLYGRAPH. Sept. 28, 1953, No. 26607/53. Class 100 (2). In a rotary letterpress machine in which the forme cylinder can readily be replaced by another, the forme cylinder 9 is housed in bearings which are withdrawable axially, rail supports in the frame then support the cylinder, the supports are lowered so that the cylinder can run out of the frame on runways, and a trolley provided with rails receives the cylinder for conveyance away from the machine. A fresh cylinder is then placed on the trolley and positioned in the machine. The cylinder 9, Fig. 3, has tapered barrel-type journals 21, 20 housed in tapered bearings 23, 24, respectively, which are slidable axially in housings by means of spindles 25, 26. Each spindle has screw-thread engagement with a bearing, and is rotated by means of a handle 28 which can be locked by ratchet and pawl means. When the bearings 23, 24 are withdrawn axially, forked rails 30 engage peripheral grooves 22 in the journals and support the cylinder 9. The rails 30 are secured to inclined racks engaged by gears 32 on a shaft 33, the latter being rotatable by gearing 35, 37 operated by a hand-crank 38, whereby the racks, supporting the cylinder, are lowered to such a position that the cylinder can be rolled out of the frame 1 along fixed rails 43 secured to the frame. The cylinder 9 is received by a trolley or carriage comprising a lower part 46 with wheels 45, and an upper part 48 with wheels 49 arranged to run on rails on the lower part 46. The trolley is moved up to the machine and the lower part 46 latched to the frame 1; the upper part 48 is moved along the rails on the lower part and then into the machine on fixed rails arranged on the frame 1 in a gap between the printing couple and the delivery apparatus 7. Folding rails 54 on the upper part 48 are then lowered and located in the frame 1 to form a continuation of the fixed rails 43, so that the cylinder 9 can be rolled on to the upper part 48 and then conveyed away by the trolley. This procedure is reversed when the new cylinder 9 is introduced into the machine. When the bearings 23, 24 are moved into position over the journals 21, 20, pins 40 on the bearings enter holes 39 in the rails 30 to prevent the latter being lowered during operation of the machine.

Title: Improvements in or relating to processes for the manufacture of sweetened condensed milk
IPC: A23C9/00
Filed: 1963-07-09
Abstract: In the production of sweetened condensed milk, sugar is mixed with standardised milk and the mixture is pasteurised, concentrated under vacuum using a multiple-effect evaporator, subjected to at least one homogenisation and seeded with lactose crystals at a temperature below 25 DEG C., the steps of pasteurising, concentrating and homogenising being effected in a continuous manner.  In a preferred procedure, the concentrated mixture is cooled to between 25 and 30 DEG C., is subjected to a first homogenisation in a pressure homogeniser is cooled to about 20 DEG C. and is then submitted to a second homogenisation by means of a colloid mill.  Alternatively, the mixture is homogenised immediately after concentration, at the temperature of concentration, and is then cooled in a continuous manner to a temperature below 25 DEG C.  The standardised milk is derived from fresh milk or reconstituted milk powder to which butter fat or vegetable fat may have been added.  Crystallised and ground sugar or sugar syrup may be employed; a portion of sugar syrup may be added during the last stage of the concentration.  According to an example, 1032 kg. of standardised whole milk are mixed with 179 kg. of crystallised sugar about one hour before concentrating; mixing is effected with vigorous stirring for 40-45 minutes, after which the stirring is continued at reduced intensity.  The sweetened milk is pasteurised at about 130 DEG C. by pumping it through a tubular heat-exchanger at a rate of 25 litres per minute and concentrated to 74.15% total solids content in a double-effect falling film evaporator operating at about 80 DEG C. for the first stage and 45 DEG C. for the second.  The concentrated mixture, containing about 43% of sugar (sucrose), is then cooled to a temperature of 27 DEG C., homogenised under a pressure of 20-25 kg./cm2, is cooled to 20 DEG C. and is subjected, in order to adjust its viscosity, to a second homogenisation utilising a colloid mill.  Finally the product is seeded with lactose crystals and canned under aseptic conditions.

Title: Improvements in or relating to electronic keyboard instruments
IPC: G10H1/055
Filed: 1962-07-17
Abstract: 983, 012. Electrophonic musical instruments. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 17, 1962 [July 20, 1961], No. 27434/62. Heading G5J. In an electronic keyboard instrument the oscillations produced by tone generators are fed to a member passing them only when there is impressed on it a voltage, which is produced without the use of mechanical contacts when a key is actuated and with a value depending on the intensity of touch, and which thereafter decreases to zero. Fig. 6 depicts an instrument having a tone similar to that of a piano. Each key, Fig. 3, moves a permanent magnet 3 relatively to the poles 8, 9 of a magnetic circuit, thus inducing in coils 10 and 65 voltages which charge condensers 11 and 32 respectively, so allowing diode 25 to pass the saw-tooth like waveform of Fig. 1, produced by combing three square waveforms. The condenser 32 discharges through resistor 41, to allow repeated playing of a note; and the condenser 11 is discharged through a network 26, 27, 28, 29, 21, by the passage of oscillations, thus producing a piano-like decay of the note and change in harmonic quality with decrease of amplitude. On release of a depressed key, the corresponding magnet 3 saturates the magnetic path 35 and thus causes the inductance of coil 33 to fall, so that a high frequency voltage is able to discharge condenser 11 rapidly, thus damping the note. A switch 36 acts as a sustaining pedal. The output corresponding to six key circuits I is fed to a single transformer 43 supplying a low pass filter which removes undesired high harmonics. The output of five six-key units II is fed to a common push-pull amplifying and reproducing circuit III. The oscillations may be produced from twelve Hartleyoscillator circuits by bi-stable multivibrators. A third harmonic may be fed through resistor 91 and diode 92. An alternative circuit and operating key arrangement are described, Figs. 2 and 7 (not shown).
