Title: Improvements in or relating to ink fountains for printing presses
IPC: B41F31/06
Filed: 1952-09-17
Abstract: 721,788. Inking-apparatus. GOSS PRINTING PRESS CO. Sept. 17, 1952 [Feb. 23, 1952], No. 23348/52. Class 100 (2). In an immersed roller ink fountain the trough has, between a pair of spaced vertical end walls, a forwardly and downwardly sloping rear wall 26 from the lower edge of which extends a horizontal apron 28, the apron being further from the roller than is the rear wall; also between the end walls a removable rectangular panel 38 is sealed to the trough by manually releasable means, the panel extending close to the roller and forming a V with the wall 26. The trough may thus be of relatively small capacity while not presenting cleaning difficulties, so that a colour change may be carried out easily and with minimum, ink wastage. In the newspaper-press ink fountain shown which has transverse vertical dividing or end walls 34 at page-spacing, when the panel 38 is removed from any one trough by its handle 52, ink in the trough runs on to the apron 28 which has an ink-retaining plate 30 detachably secured to its front edge by thumbscrews 32; removal of the latter allows the ink to be scraped into a suitable receptacle, and the space provided between the fountain roller 14 and the apron 28 allows cleaning implements to be readily inserted. When the panel 38 is in use, sealing strips 40, Figs. 1 and 4, fixed beneath its lower and side edges by screws 42 and clamping strips 44, are pressed on to the edges 50 of sealing bars 46 fixed to the walls 26, 34, by a pair of clamping devices comprising eccentrics 66 on shafts 56 rotatable in brackets 60, 58 on the walls 26, 34; the eccentrics are turned by their square heads 66a to engage the lower flanges 64 of Z-section strips 62 on the sides of the panel 38; the lower edge of the panel 38 is stiffened by an angle strip 38a.

Title: A starting device for internal combustion engines started by compressed air
IPC: F01L13/00
Filed: 1928-08-14
Abstract: 321,468. Haugsted, F. V. Aug. 14, 1928. Starting. - Compressed air for starting is supplied to the engine cylinder by a reciprocating slide valve 19 having two unequal pistons 24, 25 and actuated by a cam 18 on the cam shaft 1. The valve casing 3 has two cavities 21, 22 separated by a partition having an opening 23 of the same diameter as the piston 24 of the valve, which is normally held away from the cam 18 by a spring 20. When the supply of compressed air is turned on by means of the cock 17, the air pressure brings the face 27 of the valve into engagement with the cam 18 and air is supplied through the pipes 10 to the engine cylinder. For supplying air to two cylinders, the cam 18 may have a recess and a swell for moving the valve into two different axial positions at which pipes 10 are located. In other forms, a cam 18, or a number of cams placed side by side on the shaft 1, may actuate a valve such as 19 for each cylinder, the valves being arranged radially around the shaft or side by side.

Title: Improvements in, and relating to, the pneumatic conveyance of coal and other materials
IPC: E21F13/04
Filed: 1926-09-22
Abstract: 282,499. Dorman, Long, & Co., Ltd., and Kirby, M. R. Sept.; 22, 1926. Pneumatic conveyers.-Coal brought from the working face by a pneumatic conveyer e is received in a chamber d which is connected indirectly to the pumps f through a chamber g provided with means for separating the coal dust from the air. The separated dust passes to a chamber j which is connected to the pumps through a booster m and communicates with a filtering chamber o at the surface by a pipe line n. The filtered air passes from the chamber g through the pipe i to the pumps f which force it through the pipe k to the booster m and thence through the pipe l to the chamber j. The dust discharged from the chamber o is ready for use as pulverized fuel, and the filtered air from this receptacle may be directed for use in a furnace or discharged into the atmosphere. The dust and air delivered to the chamber o may be transferred directly to a pulverized fuel burner. The coal in the chamber d is discharged into tubs. The booster m may be dispensed with. Specification 211,616, [Class 78 (iv), Loading &c.], is referred to.

IPC: A62C99/00
Filed: 1928-08-14
Abstract: 296,404. Kidde & Co., Inc., W., (Assignees of Mapes, D.). Aug. 31, 1927, [Convention date]. Fire-extinguishing by gases; portable pressure reservoirs; sprinkling apparatus.-An extinguishing fluid held under its own gas pressure in a container or group of containers is released by means actuated by a device operated by externally controllable gas pressure. As shown, cylinders a, Fig. 1, of liquid carbon dioxide are connected by pipes b<1> to discharge piping b<2>. Each cylinder has a discharge device b comprising a frangible sealing disc and a cutter operated by an arm b<3>, all the arms b<3> being operated simultaneously by links b<4>, cords c and pistons d. The latter are operated by gas pressure supplied from control cylinders f, Fig. 2, through a pipe e<2> and a conduit e which has a bleeder nozzle e<1> to prevent actuation of the pistons owing to gas leakage from the cylinders f. The cylinders f are opened by weighted arms f<3> when a trigger mechanism g is released, and are supported on a weighing device h for the indication of any gas leakage. The cylinders f are sealed by a pair of discs j<2>, j<3>, Fig. 3, separated by a channelled washer and adapted to be pierced by the rotary cutter i. The disc j<2> is arranged to rupture readily if undue heating causes a dangerous pressure in the cylinder, the gas then escaping by way of the channelled washer and an outlet j<6>, thus avoiding accidental operation of the pistons d. Alternatively, the cylinder heads comprise a separate safety valve sealed by a readily frangible disc. Each piston mechanism, Fig. 6, comprises a tube d with a gas inlet d<4> and outlet d<5>, and a piston head k and rod c<2> connected to the cord c. When the control cylinders are opened, gas entering at d<4> forces the piston below the outlet d<5>, opening the main cylinders a and allowing the control gas to escape at d<5>. The piston k comprises a check valve k<5> which allows any gas leading from the cylinders f to pass below the piston head. A relief valve d<8> at the lower end of the tube d permits escape of any gas confined below the piston head and prevents, for example, the entry of moist air into the tube. In a modified system, the controlling gas from the cylinders f is passed from the outlet d<5>, by suitable piping into the main discharge piping b<2>.

Filed: 1951-10-16
Abstract: 707,664. Friction clutches. HOBBS TRANSMISSION, Ltd. Sept. 29, 1952 [Oct. 16, 1951], No. 24087/51. Class 80 (2) A rotary driving casing 10, enclosing a friction clutch 16, forms a sealed reservoir from which a liquid, e.g. oil, is supplied through a scoop-tube 49 to a stationary body 26 surrounding the output shaft 14. and thence to a stationary pump unit 27, mounted either internally .or externally of the casing and serving to supply pressure liquid to a diaphragm 21 for clamping a driven clutch disc 16 to the driving casing through a heat-insulator plate 24 and presser-plate 17. Two gear pumps are used, one 28, 27 driven by the input casing 10. the other 30, 29 by the output shaft 14. A two-position lever-operated valve 37 controls supply of pressure-liquid from the pumps to the diaphragm.through passages 38 and a pressure responsive valve 42, which, in the absence of inwardly acting liquid-pressure is spring-pressed outwards to exhaust the diaphragm. at 47, 48. The rotating housing has also a centrifugal valve for exhausting the diaphragm for automatic de-clutch at low. speeds as described in Specification 707,313 and relief and by-pass valves are provided. Leakage liquid at 55 may be circulated between the friction facings and also through openings 54 between the presser- and insulator-plates 17, 24. To reduce viscous drag on the scoop tube 49, it is pivotally mounted and spring-pressed into the liquid so that the drag of the rotating liquid annulus, opposing the spring, keeps the forward-facing mouth of the scoop-tube just within the liquid surface. The tube-loading spring, Fig. 3 (not shown), is a tension coil-spring acting on a vary-' ing leverage-arm to maintain constant torque on the tube in all positions. In Fig. 2 (not shown), this spring is replaced by a torsionally flexible axial tube carrying the scoop-tube. Specifications 628,499 and 673,737 also are referred to.

Title: Improvements in stereoscopic viewers provided with an interocular adjustment
IPC: G02B27/22
Filed: 1952-09-30
Abstract: 714,899. Stereoscopes. SAWYER'S, Inc. Sept. 30, 1952 [June 17, 1952], No. 24464/52. Class 97(1) In a stereoscope, the lateral separation of the eyepiece lenses is adjustable to suit the interpupillary distance of the user and pivoted transparent blocks in the light path between the eyepiece lenses and the stereoscopic pair of pictures being viewed are simultaneously adjustable by one movement of a control member to maintain the lines of sight through the two eyepieces lenses parallel, while a different movement of said control member effects focusing of the eyepiece lenses. The stereoscope shown comprises two moulded parts, 10. 11 which engage along a viewing plane 12 in which a disc 16 carrying several pairs of stereoscopic transparencies 17 is disposed, this disc beng inserted through a slot 19 in the top of the stereoscope and having perforations engaged by projections on a plate 20 rotatable by a lever 24 to dispose any one pair of transparencies in the light path through glass panes 14 in the part 10. Part 11 of the stereoscope accommodates eyepiece lenses 29 in barrels 30 which are axially slidable in blocks 32, the lateral separation of which is adjustable by a rod 45, the flutes of which engage a rack 50 on each barrel 30. Blocks 32 have projections 35, 37 passing through slots in upper and lower mounting plates 33, 34, the projections 35 being interconnected by a linkage so that the blocks move towards or away from each other according to the direction in which rod 45 is moved, this rod having thereon snap rings between which one block 32 is accommodated. Thus axial movement of rod 45 causes lateral separation of the eyepiece lenses 29 while rotation of this rod causes focusing adjustment of the lenses 29. Between the transparencies 17 and each lens 29 is pivoted a parallel sided transparent block 60, a pin of which is engaged by a yoke 70 on each block 32. Thus, as the lateral separation of the block 32 is varied, the transparent blocks 60 are pivoted to maintain the lines of sight parallel.

Filed: 1975-06-09
Abstract: 1511338 Electronic pianos WURLITZER CO 9 June 1975 [8 July 1974] 24579/75 Heading G5J A circuit for simulating the attack-decay envelope of a piano note in an electronic instrument comprises a first-charging circuit 21-23 which is charged with a keyswitch 24 in one position; a second charging circuit 26, 27 which is charged under the control of the first charging circuit when the keyswitch is in the play position; a gate circuit 41 variably enabled by the second charging circuit; and means 29-32 for rapidly discharging the second charging circuit when the keyswitch is moved to the rest position. In Fig. 1 capacitor 21 is charged from B + supply when the keyswitch is in the rest position. When the keyswitch is moved capacitor 21 begins to discharge through resistors 22, 23. Depending on the speed of movement (touch) the charge remaining when the keyswitch reaches the play position is transferred to capacitor 26 which commences to discharge through resistor 27. The voltage across capacitor 26 which is used to control gate 41 has a rapid rise and a relatively slow decay, the amplitude of the peak depending on the speed of operation of the key. When the key is returned to the rest position transistor 29 is rendered conductive via resistor 30 and therefore rapidly discharges capacitor 26 through resistor 32. Threshold transistors (zener diodes) 36, 37 responding to the amplitude of the control voltage control further gates 39, 40 to add in a variable proportion of the second and fourth harmonics near the peak of the attack-decay envelope. In an alternative circuit (Fig. 4), immediately after keyswitch contacts 91, 92 are closed an electronic switching circuit 90 becomes conductive to charge the second capacitor 100; when a first capacitor 92 is fully charged the circuit 90 cuts off and capacitor 100 begins to discharge. When the keyswitch is released capacitor 100 is rapidly discharged through diode 97.
