Title: Improvements in or relating to apparatus for producing curved stereotype printing plates
IPC: B41D5/00
Filed: 1919-08-08
Abstract: 152,813. Linotype & Machinery, Ltd., (Wood, H. A. W.). Aug. 8, 1919. Printing-surfaces; stereotype.-Apparatus for casting curved stereotype plates, particularly tubular plates, comprises a cylindrical casting box and cylindrical core which is provided with one or more helical grooves which form helical ribs on the cast plate, so that the plate is ejected axially from the casting box by rotating the core. The core is provided with a knife which shaves the rib on the plate during its ejection, and after ejection of the plate a saw is caused to travel round the plate to sever the tail. As shown, a core 13 provided with a helical groove 19 is rotatable in an undivided fixed casting box 10 which is provided with a vertical groove to receive a matrix clamping bar 22 which extends above the top of the box 10. The core and box are hollow for the circulation of cooling water. A shaving knife 18 is fixed in the top of the core opposite to the bar 22, and the upper end of the core is conical to receive the shavings and conduct them to a central passage through the core. A worm wheel 29 fixed to the core meshes with a worm 28 on a shaft 25 which may be connected by a pedal operated clutch to a loose driving pulley. The shaft 25 is geared to a vertical shaft 31 which is also. geared to a shaft 32 carrying a worm 33 meshing with a worm 35 loose on a shaft 48. A hub 36 fixed to the shaft 48 carries a spring-pressed pin 37 adapted, when required, to engage a hole in the worm 35 to cause the shaft 48 to be driven. The pin 37 is normally held raised in an inoperative position by a sliding cam 40 engaging under the head 39 of the pin, the cam 40 being carried by spring-pressed rods 41 which may be operated to release the pin 37 by means of a bell-crank 43 operated by a chain 45. A gear 50 on the shaft 31 also drives a gear 49 loose on the shaft 48 and gearing with a pinion 51 on a shaft 52 carrying a tail severing saw 54. The shaft 52 is carried by a member 55 fixed to the shaft 48 and forming a guide for the tail during the severing operation, as shown. Pivoted claws 57 serve to hold the severed tail. In operation the matrix is placed in the apparatus with its ends engaging grooves in the bar 22, and a cylindrical pouring sheet P, Fig. 7, is arranged above the matrix. This sheet is provided with strips p which cause the plate to be cast with a gap a<1>, Fig. 8, of sufficient width to allow the plate to be raised past the saw 54 without contacting with it. The plate is cast in the usual manner, and, when cool, the driving clutch is closed, causing the core to rotate, and the plate, together with the pouring sheet and matrix, are raised until the plate rests upon the top of the core. During the ejection the rib is shaved by the knife 18. The operator then withdraws the cam 40, allowing the shaft 48 to be operatively engaged with the worm 35 so that the saw 54 is carried round the plate to sever the tail. After a complete revolution of the shaft 48, the pin 37 is automatically raised by the cam 40.

Title: Water-sensitive flow monitor
IPC: F16L55/00
Filed: 1964-05-11
Abstract: 1,064,986. Filters for liquids or gases. FRAM CORPORATIONS. May 11, 1964 [May 17, 1963], No. 19551/64. Headings B1D and BIT. [Also in Division G1] When liquid fuel containing an excessive proportion of water passes through a stack of slightly resin-impregnated paper discs 16, the water softens them; the softening causes collapse of creping or embossing on their surfaces, thereby permitting closer packing under the differential (inlet) pressure acting on a diaphragm 25. Such closer packing reduces flow between the discs, the reduced flow in turn effecting increase of differential pressure. The increased differential pressure causes still closer packing until all flow ceases. If the fuel carries solid impurities rather than water, the pressure needed to compress the discs is greater. Spring 24 is a tension spring to retard diaphragm movement. It may be omitted, or replaced by a compression spring. The device may be used in a compressed-air line to prevent passage of air-borne water.

Title: Improvements in and relating to signs
IPC: G09F13/30
Filed: 1930-07-02
Abstract: 362,372. Moving and changing signs. CRAIG, R. M., 219, Water Street, San Antonio, Texas, U.S.A. July 2, 1930, No. 20100. [Classes 3 (i) and 3 (ii).] Neon, argon, helium, xenon, crypton, or other electric discharge lamps 25, 29, 32, 33 are mounted on a rotating head 10 and are intermittently lit so as to give in turn the effect of one, or a number of circularly arranged, displays of the lamps. The head 10 is carried by a shaft 4 rotated at from 750 to 1200 revolutions per minute by a motor 18. A commutator 42 having a ring 68 and contacts 70 for the low tension, and rings 44 for the high tension, connections is mounted on the shaft 4. A secondary shaft 56 rotated at a much slower pace carries cam contacts 57 .. 64. A transformer 22 is provided for each lamp, together with an additional transformer should the transformers 22 have open cores. The high tension circuit is always made through brushes 39, 48, but the low tension circuit is broken at intervals by being made alternately through the slowly rotating cams 57, 58, the make through the cam 57 being continuous and that through the cam 58 being intermittent through the contacts 70. Fig. 5 shows a modification in which one of the lamps 81 is lit continuously, and the others 78, 79, 80 are in series and are lit intermittently under control of a thermal, mercury, or other switch 110. When the switch arm is on contact 108, the transformer 93 causes the display to make a steady pattern, the circuit being through lead 94, brush 95, and back through lead 92, but when the arm is on contact 107 the circuit is made through lead 106, brush 105, intermittent contact 103, brush 100, and lead 99, thus giving a different steady display. The head 10 may be of circular, star or other shape, and the lamps may be attached to wooden blocks 31 by a cellulose cement. In large signs the effect of centrifugal force may be reduced by slowing down the speed of the head and duplicating the lamps and their contacts. The frequency of illumination of the lamps may be varied by altering the spark gaps in the transformers.

Abstract: 1,141,695. Automatic exchange systems. INTERNATIONAL BUSINESS MACHINES CORP. 9 May, 1966 [10 May, 1965], No. 20413/66. Heading H4K. [Also in Division G1] Apparatus for transferring signals from an input line to one of a plurality of output lines includes means to modulate a beam of light in accordance with a signal on the input line, a plurality of photosensitive transducers each associated with an output line and means in the light path operable in response to a signal distinctive of a particular output line to deflect the light beam to the transducer associated with the particular output line. An exchange for selectively interconnecting telephones 11, 12, 13, 14, Fig. 3, comprises a plurality of birefringent plates E1a-E4a and E4b-E1b separated by electro-optic devices, e.g. KDP crystals which rotate the plane of polarization by 90 degrees. The speech signals from telephones 11, 12, 13 and 14 modulate light-emitting diodes D1a, D1b ... D4a, D4b, respectively. The birefringent devices are arranged to transmit the ordinary ray without deviation and the extraordinary ray displaced by a distance equal to the spacing of the diodes. If a call is to be set up from 11 to 13 electro-optical devices EO1a and EO3b are energized. This makes light emitted from diodes D1a ... D4a extraordinary and therefore displaced downwards by all the birefringent plates E1a ... E4a and only light emitted by diode D1a passes through the aperture 25. This light is deflected upwards by plates E4b and E3b before being made ordinary by the electro-optic device EO3b whereafter it passes horizontally to the photo diode P3a associated with telephone 13. The return speech path from D3b to P1b is simultaneously set up by energization of electro-optic devices EO3d and EO1c. For operation as a time division multiplex system, telephones 11-14 are scanned by a scanner 44 which passes the calling and called members to a central control 48 which circulates these numbers through memories M1 and M2 to close selected switches S1a- S4a and S4b-S1b energizing the electrooptical devices. In another embodiment, Fig. 4 (not shown), the thickness of the birefringent plates are in a geometrical progression with common ratio 2 and a combination of electrooptic devices may be energized which is in effect a binary coded indication of the calling or called number.

Abstract: 1,264,804. mage analysis. IMAGE ANALYSING COMPUTERS Ltd. 29 April, 1969 [1 May, 1968], No. 20613/68. Heading G4D. Parameters from features on a screen are computed from successive line scans, detection of the last line scan of a feature producing an anti-coincidence pulse which releases the parameter signal stored relating to that feature. Whenever the scan is passing over a feature an intersect pulse is applied to 10. Each scan is compared with the preceding scan by loop 12, 14, 16 so that a pulse V<SP>1</SP> is applied to differentiator 32, V<SP>1</SP> starting when an intersect pulse starts and stopping at the end of the intersect pulse or at the end of a coincident pulse, whichever is the later. The bottom right hand corner of a feature is detected by an anti-coincidence circuit 18-26. A selected parameter of each intersect pulse is registered in module C. Module B holds the computed value up to the previous scan, and A computes the new value. The anti-coincidence from gate 22 clears the modules. The A, B, C modules are as disclosed in Specification 1,264,805. The parameters can be height, width, area or perimeter. Figs. 7, 7A show a system for determining the number of features having a length L VA<SP>2</SP> + F<SP>2</SP> within prescribed limits and the total length of such features having a width A/L within prescribed limits. As disclosed in Specification 1,264,807, the shadow of a feature can be reduced (Figs. 2, 2A, not shown). Also a feature detected within a shadow can be processed by a second channel 96, Fig. 4. If the feature extends beyond the shadow, Fig. 6, then the information relating to feature 108 is transferred by 106 to the first channel 90.
