Title: Improvements in delivery mechanism for use in printing machines
IPC: B65H29/16
Filed: 1930-05-22
Abstract: 354,875. Sheet-delivery apparatus. QUICK, C. G. and MARSHALL, C. W., 109, Borough Road, London. May 22, 1930, No. 15846. [Class 100 (i).] In delivery mechanism for a rotary printing machine there is combined with the rotatable fly delivery device a conveyer device, and means are provided for adjusting the relative positions of the two. Rotary flies 1, 2, 3 comprising a series of curved arms deliver to conveyer chains 4, 5, 6 and thence in turn to a conveyer belt 30 .. 33. The conveyer chains are mounted in a frame comprising side members 9, 10 and cross members 11, 12 and are driven by chains passing over chain wheels 13 secured to a shaft 14 on which the frame is pivotally mounted. Mounted on the cross member 11 are arms 19, 20, 21 carrying gearing wheels which tension the upper portion of the chain. The side members 9, 10 rest on eccentrics 22, 23 on a shaft 24 to which is secured a worm wheel 25 in mesh with a worm 26 on a spindle provided with a hand wheel 30. The worm wheels are self-locking and the position of the chain frame and chains relatively to the fly 3 is adjusted by moving the eccentrics. To enable a count of the products to be made, a kicker arm 49 is mounted on a cross shaft 50 driven by an arm 51 through a roller 52 which'engages a disc 53. This disc has two notches 54. 55 and it is mounted on the main driving shaft 16. The kicker acts to push one copy diagonally periodically. A further kicker 56 may be provided to eject one copy a further distance than but parallel with the adjoining copies, this unit being rendered inoperative when a high speed conveyer is employed and is only used for hand collection. Side screens 57, 58 mounted on supports 59, 60 are used to shield the papers from draughts and the support 59 is arranged to be clamped at varying angles according as to whether the cam copy is to be ejected angularly or parallel. The conveyer member 33 which takes the papers from the chains is mounted on a frame which is pivoted at 41 and clamped in the necessary position by bolts 43, 44.

Title: Control circuit
IPC: H02P7/29
Filed: 1966-04-12
Abstract: 1,093,207. Control of D.C. motors. SQUARE D CO. April 12, 1966 [April 21, 1965], No. 15868/66. Heading H2J. A battery-operated truck is driven by series motor M which is prepared for forward starting when contactor A is energized. Capacitor 5C discharges to render rectifier 2SCR conductive for a short period and supply a preset charge to capacitor 1C. Capacitor 6C charges at a controlled rate, rectifier 1SCR becoming conductive when the voltage across the capacitor 6C reaches a predetermined value. This energizes the motor M and impresses a commutating charge on capacitor 1C by current from transformer winding TS1, capacitor 4C being charged simultaneously at a constant rate. The rectifier 2SCR conducts when the charge on capacitor 4C reaches a predetermined value so that the commutating charge on capacitor 1C is delivered to rectifier 1SCR and windings TS1, TS2, TP, of a saturable transformer to render rectifier 1SCR non-conductive. Thus, the motor is supplied with a current pulse of predetermined duration each time the rectifier 1SCR conducts. The rate of charge of capacitor 6C is determined by the conduction of transistor 5T associated with capacitor 7C which is charged through potentiometer P2. The motor is thus accelerated smoothly from a minimum speed determined by the initial charge on capacitor 7C until the capacitor is charged to a value determined by the setting of the potentiometer. The voltage across capacitor 1C reverses in accordance with the state of conduction of the rectifier 1SCR, this capacitor being connected to capacitor 3C which renders transistor 2T non-conductive when the motor speed increases to a maximum. Transistor IT is then rendered conductive to switch on rectifier 3SCR which energizes contactor SC for connecting the motor directly to the battery. The motor may be plugged through diode D2 prior to reversal, and, during the interval of transition between the operations of the forward and reverse contactors, relay H responds to reduce the conduction of transistor 5T and increase the " off" periods of rectifier 1SCR. This reduces the field excitation of the motor during generator action, the adjustment of potentiometer P4 controlling the rate of deceleration. When the motor reaches zero speed, relay H is de-energized and controlled acceleration in the reverse direction is initiated. The winding TS2 on transformer T limits the current rise through rectifier 2SCR and resets the residual magnetism of the transformer core so as to determine the amount of energy stored in capacitor 1C.

Title: Improvements in or relating to a ball point pen
IPC: B43K7/03
Filed: 1964-04-16
Abstract: 1,003,653. Reservoir pens. DOLEO S.A. April 16, 1964 [May 3, 1963], No. 15879/64. Heading B6P. In a ballpoint pen of the type wherein the ink is fed to the ball under the action of a mass of compressed gas produced inside the reservoir through reaction between two chemically active components, a hollow, triangular crosssection member 6, Fig. 3, is press fitted into the reservoir to define channels 7 and 8, Fig. 4. One chemically reactive component 9 fills the channel 8, and the other component 10 fills the channels 7. A plug of neutral pasty substance 11 prevents the components 9 and 10 from reacting chemically. A diaphragm 12 with an orifice defines a mixing chamber 16 below the member 6. A plug 17 at the top of reservoir traps air under pressure in the space 20. When the ink is used, the level in the reservoir drops. The pressure of the air in the space 20 forces the two chemical components 9 and 10 down their respective channels so that they chemically react in the chamber 16 to form a gas 21. When sufficient gas has been produced and the pressure of the gas balances the pressure of the air in the space 20, equilibrium is achieved until the level of the ink 3 again drops. The pasty plug 11 moves down the channel 8 as the chemical component 9 is used, thereby maintaining a barrier between the two components 9 and 10. Various types of member 6 are described, Figs. 5 to 17 (not shown), all defining at least two channels for the two chemically reactive components 9 and 10. One example of the chemical component 10 is: A polyamide resin is a Versamide diluted in a proportion as of 1/ 3  in a solvent such as benzyl alcohol. A method of manufacturing the ball point pen comprises the following steps: (2) Ink is injected at the writing end into the reservoir 1 and the terminal portion 4 inserted. (2) The diaphragm 12 is fitted inside the rear end of the reservoir 1 and urged forward by a hollow piston 29, Fig. 20. (3) The tubular member 6 previously loaded with a predetermined amount of the active substance 9 and the plug 11 from injectors 35 and 36 respectively, is urged from a rotary support 32, Fig. 21, into the rear end of the reservoir 1 by an axially moving punch 38. (4) The second active substance 10 is introduced into the rear section of the reservoir 1 by an injector system, Fig. 23. (5) The reservoir is closed with the rubber plug 17 together with a predetermined amount of sealing paste 53 by apparatus illustrated in Fig. 24. (6) The reservoir 1 is finally sealed with the knurling wheel 49 and rollers 52 as shown in Fig. 25.

Title: Improvements in the treatment with hydrogenating gases of carbonaceous materials
IPC: C10G1/06
Filed: 1935-06-01
Abstract: <PICT:0459232/III/1> In the treatment of carbonaceous materials with hydrogenating gases congestions in the apparatus, particularly in the tube heaters, are mitigated by ascertaining attendant fluctuations in pressure and introducing into or before that part of the apparatus, where the fluctuations occur, a quantity of liquid, e.g. viscous oil not substantially volatile under the reaction conditions.  The oil is preferably introduced so as not to mix with the reacting materials and to avoid intermixing no pumps or other devices causing mixing should be situated between the point of introduction of the oil and the point of congestion.  If the congestion is caused by deposition of salts, e.g. ammonium chloride or carbonate, water is introduced as the liquid.  Small fluctuations in pressure are measured by a U-tube U half filled with mercury and connected to a pressure balance D of usual type through lines L, M, and a catchpot B.  The free ends O, P of the balance and U-tube are connected through catch-pots C, A, to the points of the apparatus at which the difference of pressure is to be measured.  A plant comprising preheaters K, reaction tubes Q, R, separator U, cooler V and heat - exchanger J is provided with three such pressure measuring devices so as to measure pressure difference between the ends of the heat-exchanger J, preheater K, and cooler V, respectively, and pumps II, III, IV are provided for the introduction of flushing liquid into the parts referred to.
