Title: Wall board and method of manufacturing the same
IPC: B28B19/00
Filed: 1935-10-07
Abstract: 451,389. Wall boards ; moulding by rolling. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Walper, G. M. ; Mountain View Apartments, South James Street, Hamilton, Ontario, Canada) Oct. 7, 1935, No. 27632. [Class 87 (i)] [See also Group V] A wall board or plaster board comprising a layer of plaster or other cementitious material between face sheets has the edges reduced in thickness compared to the rest of the board, by providing outwardly extending projections in one of the face sheets at the zones where the board is to have reduced thickness. A lower face sheet 13 supplied from a spool 13<1> passes first between rollers 43 having a cooperating projection and recess 44 to produce spaced indentations 41 along a margin of the sheet, after which the sheet passes between rolls 19 with projections 21 which produce spaced rows of perforations 16. The sheet then passes between rolls 24 with projections which produce longitudinal perforations. The edges of the perforations form projections which lift the sheet, in the region of the perforations, clear of the supporting surface. Side formers 27 turn up the margins of the sheet to give the sheet a trough section, and cementitious material 17 is supplied to this sheet by a nozzle 18. An upper face sheet 14 supplied from a spool and having a width equal to the distance between the sides of the trough formed by the lower sheet, is pressed on to the cementitious material by a roller 30, and the upstanding sides of the lower sheet are then turned over the top sheet by side forming rollers 67. The formed compound sheet is fed by a conveyer to travelling cutters 32 which move with the sheet and sever it along the lines formed by the perforations 16. The cutters are rendered operative periodically by an electric circuit which is closed when a spring 39 forces a feeler 40 into the recesses 41 which have previously been formed in the side of the sheet by the rolls 43. The rolls 19, 43 are geared together and are operated periodically, one revolution at a time, by an electric circuit similar to that governing the cutters and controlled by a feeler 62 which engages in the transverse perforations 16. The feeler is adjustable so that the spacing of the rows 16 may be varied to alter the lengths of the wall boards produced.

Title: Improvements in and relating to shaft bearings
IPC: F16C32/06
Filed: 1930-09-16
Abstract: 350,844. Lubricating bearings. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Wade, R. B. ; 107, Aspen Road, Swampscott, Massachusetts, U.S.A.) Sept. 16, 1930, No. 27666. Convention date, Sept. 16, 1929. [Class 12 (ii).] Lubricant is supplied under pressure to a horizontal groove 12 in that side of a shaft bearing at which the movement of the shaft is upwards, and is discharged through a pipe 16 from a diametricallyopposite groove 15, the ends of the groove 15 being connected with inner annular grooves 20 between which the groove 12 is arranged, and each groove 20 is formed, adjacent the groove 15, with a dam 21. Escape of oil from the ends of the bearing is prevented by outer annular grooves 17 formed with dams 18 opposite the dams 21 and provided in the lower part of the bearing with discharge passages 19. The upper part of the bearing is provided with a central recess 11. Oil which reaches the grooves 20 is carried round, with the oil in the recess 11, into the channel 15 whence it is forced into the pipe 16.

Title: Improvements in and relating to mechanisms for controlling type-cutting operations
IPC: B31B1/90
Filed: 1954-09-24
Abstract: 775,129. Adhesive-tape applying machines. WEBER & CO., Inc., H. G. Sept. 24, 1954 [May 12, 1954], No. 27707/54. Class 73. In a machine for applying tear-strips to carton blanks 12, Fig. 2, fed through the machine on a platform 15 by rollers 10, 11, pressure-sensitive adhesive tape 18 drawn from a supply roll (not shown) is applied to the blanks 12 by a roller 26 and the tape is severed near the trailing edge of a blank 12 by means of a cutter 39 forming part of a spring- urged pivoted cutting assembly 37 including also a sensing roller 90 which, while in engagement with the blank 12 prevents operating of the cutter 39 and permits it to operate only when the blank has moved out of engagement with the roller 90. The assembly 37 is normally maintained in a raised position by means of a spring 51 connected thereto by parallelogram linkage. Limit switches 70, 71 have arms 72, 75 actuated by the blanks such that when the arm 72 rests on the platform 15 and the arm 75 rides on a blank 12, the circuit of a solenoid 84 is closed to retract its armature 85 and tension a spring 87 which acts to urge the cutting assembly in a downward direction against the action of a spring 51. The sensing roller 90 prevents full downward movement however until the blank has moved from under it. In operation an end portion 20, Fig. 1, of the tape is first applied to a platen 21 lying slightly below the level of the platform 15, and an unapplied portion 22 extends upwardly around the applying roller 26 and thence to the supply roll. On feeding a carton into the machine, its leading edge strikes and lifts a pilot roller 31 mounted at one end of a spring-urged pivoted frame 33 which carries the applying roller 26 at the other end. The roller 26 is thus moved downwardly and applies the tape to the blank. Continued advancement of the blank peels off the tape portion 20 initially applied to the platen 21 and turns the tape back on itself so that the portion 20 is applied to the bottom of the blank. On operation of the cutter 39, a rubber tack-down pad 40 also forming part of the cutting assembly 37 applies the leading portion of the severed tape to the platen 21 for application to the next carton.

Index setting-arrangements; hammer-impression arrangements. - A taximeter with ticket printing and issuing, and record-strip printing means is fitted with type-wheels with diametrically oppositely placed similar type so that a pair of parallel platens may be used allowing a lighter construction of type wheels and a smaller easily wound clock to be used. The platens 72, 73, when released on actuation of the flag 74, are pressed towards type-wheels 18, 26, 35, by a spring 87, the wheels bearing oppositely placed sets of type to print both the ticket and the record simultaneously. An " extras " wheel 42 is arranged for simultaneous printing on both strips. The platens are pivoted to levers 85, 86, and the upper ends of these levers are connected by links, 83, 84 to a link 79 bearing a pin 80 that follows a cam slot 81 in a disc 78 on a shaft 77 driven by movement of the flag. When the pin reaches the point 82, it allows the platens to close, and continued rotation of the disc 78 lifts the pin 80 to disengage the platens. The flag cannot be turned to raise the pin until printing is completed, a lever 118 engaging a ratchet wheel on the shaft 77 until released by the pin 80 raising the outer end of a lever 121 having a spring 122 passing under the outer end of the lower 118. The ticket 106 is fed downwards from a roll 64 by rollers 95 driven by the rotation of the shaft 77 and a cam 96 actuates a lever 98 to rock a shaft 101 carrying a knife 103 to sever the ticket and allow it to fall into a holder 105. The shaft 101 is connected by a lever 100 to a lever 108 having a quadrant 109 gearing with a pinion 110 to actuate a pawl 111 whereby the record strip 65 is fed into a holder 114. The printing and issuing device is mounted in a frame detachable from the indicating device, while the ink ribbon 63 is carried by rollers on a base removable from the casing of the printing device. The indicating device may also be removed from the back-plate of the apparatus. The Specification, as open to inspection under Sect. 91 (3) (a) also comprises the following subject-matter :-The strip coils itself inside a spring 116 or a curved spring-pressed bar, and may be severed from the main strip against a cutting edge 117 when a cover 115 is removed. Date and year wheels 60, 63 for printing on the ticket only are provided. The date-wheels are set by the device shown in Fig. 4, comprising wheels 54, 55, 56 on nested shafts, the shafts having wards 51, 52, 53 to engage the corresponding nested shafts of the type wheels when the stem 155 is inserted in an aperture 48 in the casing. A similar aperture for adjusting the year wheel is provided, both apertures being covered by a plate 46 carrying a lever 45. This lever is normally held against a stop 160 by the bolt 44 of a lock preventing access to the printing device, but when the lever is freed, openings 50 in the plate 46 can be turned to register with the apertures 48. This subject-matter does not appear in the- Specification as accepted.
Patent GB-966694-A (GB)
Title: The production of copies of graphic originals by successive exposures to light and to heat producing radiation
IPC: G03G5/153
Filed: 1960-08-10
Abstract: 966,694. Copying material comprising both light- and heat-sensitive layers. MINNESOTA MINING & MANUFACTURING CO. Aug.10, 1960 [Aug. 10, 1959], No. 27747/60. Headings G2C and G2H. [Also in Division H1] Copies of graphic originals are produced on a sheet having a visibly heat-sensitive layer and a co-terminous light-sensitive layer by exposing the light-sensitive layer to a light-image of the original to produce, if need be by means of a developing step, a differentially radiation absorptive pattern in said layer, and irradiating said pattern to form a corresponding heat pattern and hance a visible image in the heat-sensitive layer. Binders e.g. ethyl cellulose, polyvinyl pyrollidone, gelatin, polyvinyl butyral, are included in the light- and heat-sensitive layers which may be on the same or opposite sides of a support, the light-sensitive layer being between the thermographic layer and the support only if the support is transparent e.g. transparentized paper of polyester. The support - may be omitted if the layers are sufficiently selfsupporting. Light sensitive materials yielding visible but impermanent images on exposure are print out materials containing silver nitrate in polyvinyl pyrollidone, blue print materials comprising ferric ammonium citrate and potassium ferricyanide, light-sensitive electron donor material such as zinc oxide, silver-activated zinc sulphide, or a photochromic compound, e.g. cobalt triethylenediamine persulphate, in combination with an electron acceptor material such as silver nitrate or gold chloride and chloroplatinic acid. These impermanent images finally result in a thin uniformly fogged layer but this may be avoided in the care of the silver nitrate print-out and blue print materials by washing with water or a dilute solution of potassium bichromate. Light-sensitive materials yielding latent images requiring appropriate development to provide visible images which need fixing if they are to be permanent are silver halide, diazo and zinc oxide-in-resin electrophotographic materials. If in developing the charge image formed on the electrophotographic material, a coloured developer containing a fusible substance such as rosin or polythene is used the heat exposure fixes the developer in the non lightexposed areas but a fusible developer is not required. The thermographic materials may comprise materials which react on heating to give coloured products such as ferric stearate and tert-butyl catechol or gallic acid; ferric stearate and an alcohol insoluble precipitate formed from hexamethylenetetramine and pyrogallic acid; or silver behenate, behenic acid, and protocatechnic acid; or a heat-transparentizable opaque layer as of fatty oil wax particles covering a thin layer containing titanium dioxide and an infra-red transmitting blue lake pigment. Specifications 673,244 and 810,863 are referred to.

Patent GB-483285-A (GB)
Title: Arrangement for automatically regulating the pitch of variable pitch propellers
IPC: B64C11/44
Filed: 1936-10-13
Abstract: 483,285. Screw propellers. VEREINIGTE DEUTSCHE METALLWERKE AKT.-GES. Oct. 13, 1936, No. 27788. Convention date, Oct. 17, 1935. [Class 114] [Also in Group XXXV] Variable-pitch propellers are adjusted by a source of electric current, the voltage of which is dependent on the speed of the propeller and an adjustable resistance is provided to vary the action of a voltage responsive relay or relays to determine the speed desired. The control may be associated with the throttle lever, and manual control of the blade pitch is provided. A reversible electric motor 8 is coupled by a flexible drive 3 to the pitch adjusting gear and a switch 6 is coupled to the gear to limit the adjustment of pitch. The motor 8 is operated automatically by relays 32, 23 for increasing and decreasing the pitch respectively, and manually, through back contacts of these relays, by a switch 28. When the engine is running at full throttle, as shown, a catch 68 on the throttle lever 67 operates a switch 65 to put two voltage responsive relay coils 53, 54 in parallel in the circuit of the generator 57, the voltage of which depends on engine speed. The adjustable resistance 63 is then in series with both coils. The relay 32 is energized by the switch contact 47 when the engine speed exceeds the range determined by the setting of the resistance, and the relay 23 is energized by the switch contact 48 when the speed falls below the range. Operation of the manual switch 28 under these conditions will adjust the propeller blades until the speed limit is reached whereupon the relay 32 or 23 will interrupt the operative manual control circuit. When the throttle lever is in an intermediate position the switch 65 connects the coil 53 directly to the generator 57 and so lowers the low-speed limit to the minimum. This gives a wider speed range without automatic pitch adjustment during which manual adjustment of pitch is operative. With minimum setting of the throttle the catch 68 opens a switch 49 in the circuit for the automatic control of the pitch to disable it. A number of resistances 63 may be connected in parallel and the number of voltage responsive relays may be increased to divide the range of variation into phases. The adjustment of the resistance 63 may be dependent upon the movement of the throttle lever.

Title: Improvements in and relating to synchronous motors
IPC: G04C3/14
Filed: 1963-07-12
Abstract: 1,055,054. Synchronous motors. GENERAL ELECTRIC CO. July 12. 1963 [July 30, 1962]. No. 27808/63. Heading H2A. The speed of a synchronous motor used for driving a clock mechanism is stabilized by connecting an additional pickup coil, inductively coupled to a mechanical oscillator system, to the input of the main D.C. energized oscillator circuit. The motor comprises a stator 12 with polepieces 28, 30, constructed to facilitate self-starting of the permanent magnet rotor 10. The stator is wound with a tapped winding com prising a major coil portion 22 connected across the output of transistor 16 in series with battery 18 and a minor coil portion 26 connected, in parallel with pick-up coil 26, to the input of the transistor. In operation the change in flux in the two halves of the stator windings causes the transistor to be alternately switched " on " and " off " and the pulses of power produce a pulsed magnetic field at the polepieces which cause the rotor to commence rotating. The pulse of power in minor coil 26 when the transistor is switched off passes through coil 20 and attracts permanent magnet rotor 46 which is mounted on torsion strip 38 of the mechanical oscillator shown in Fig. 2. Restoration of this rotor 46 to its rest position induces a reverse voltage pulse in coil 20 which switches on transistor 16 causing the cycle to repeat so that the mechanical oscillator effectively regulates the running speed of the motor. The motor may have the oscillator attached to it so that rotation of the motor rotor provides a disturbing force on the oscillator, Fig. 8 (not shown). In this embodiment the oscillator comprises two oppositely poled magnets 140, 141 supported on a shaft mounted in jewelled pivots and biased to a rest position by hair springs 131, 135. The provision of two magnets nullifies the effect of stray magnetic fields and only one magnet 141 influences pick-up coil 143. The frequency of the oscillator may be adjusted by altering the position of screw 144. The pick-up coil is connected in series with the tapped motor field coil in a transistor oscillator circuit. Specification 1,055.053 discloses a motor using an oscillator having the two magnets mounted on a torsion strip.

Contacts to a device such as a transistor, diode, resistor or capacitor formed in a semiconductor body make connection with appropriate regions of the body through holes in a passivating film and extend over the passivation to the points of attachment of external leads. To attach these leads an insulating supporting layer, either preformed or deposited, is provided on the passivated contact-bearing face of the body and semi-conductor material and passivation is removed so that the leads may be bonded to that side of each contact which meets the semi-conductor region. The invention is particularly applicable to integrated circuitsin such structures semi-conductor material is removed completely from between the various devices which, with their interconnecting contact pattern and lead attachment areas, are left attached to the insulating supporting layer. In a modification heavily doped semi-conductor of the original body is allowed to remain in the lead attachment areas and external leads are bonded to metallization on the islands thus formed. Embodiments include two two-stage direct-coupled amplifiers (Figs. 5 and 11, not shown).
