Title: Fluidic control system
IPC: F15C4/00
Filed: 1972-05-11
Abstract: 1404991 Fluid-pressure servomotor systems PROCESS SYSTEMS Inc 11 May 1972 [12 May 1971 9 Aug 1971] 22245/72 Heading G3P [Also in Divisions F2 and G4] A fluid-pressure control system provides a pressure in a chamber that is the analog of a digital signal applied to digital valves coupling the chamber to a source of constant pressure or coupling the chamber to a receiver. In the former case the chamber is coupled to the receiver, and in the latter case to the source, via one or more orifices of constant cross-sectional area. The receiver may be the atmosphere. In one embodiment, Fig. 2, the valves 36-39 of the converter control the flow between an inlet manifold 34 and an outlet manifold 35 constituting the chamber referred to above. Each valve includes a needle assembly 45 spring urged towards seat 47. When coil 52 is energized the needle assembly 45 rises to allow fluid-flow. Each valve has a screw thread 50 so that, by rotating the valve when clamping ring 56 is released, the effective area of the orifice defined by seat 47 and the raised needle 45 is adjustable. Bleed ducts 64, 65 are provided as shown, duct 64 maintaining a required minimum pressure in manifold 35 when all the valves are closed, duct 65 setting an upper limit to the flow-rate. The pressure in manifold 35 may control a movable element of a valve forming part of a system monitored by a sensor, the sensor output being fed back to a device producing the digital signals controlling the valves. The ratio of the pressure in manifold 34 to that in manifold 35 is kept at about 2:1 (for air) which is larger than the critical pressure ratio. The ratio of the pressure in manifold 35 to atmospheric pressure is kept larger than 2:1. As a result there is sonic velocity air-flow through the valves, which isolates the manifolds from one another so that pressure changes in manifold 35 do not alter the mass flow-rate through the valves. To maintain  the pressure ratio across the duct 65 it may be necessary to couple it to a vacuum chamber. In a second embodiment, Fig. 6, each electrically controlled valve 95 controls the flow between an inlet duct 81 and an outlet duct 82. A needle valve 97 permits adjustment of the flow-rate for each valve. The inlet and outlet ducts are connected by a bleed channel including needle valve 93. The outlet duct 82 has a bleed 88 to atmosphere.

Abstract: 1316043 Microwave filters SPERRY RAND CORP 19 April 1971 [9 March 1970] 22247/71 Heading H1W [Also in Divisions H2 and H3] A high frequency i.e. microwave energy converter comprises an avalanche diode 7 conductively bonded between a conductive wall 5 and an inner conductor 1 the conductive wall 5 short circuiting the tubular outer conductor 2 of a hollow transmission line 1, 2, circuit means (53, 54, 56 Fig. 3, not shown), for biasing the avalanche diode with a unidirectional electric field below its break down field, coupling means 40, 41 for supplying a high frequency carrier field #F across the diode superimposed on the undirectional field so that the total field across the diode rises above a critical avalanche field current triggering value for exciting amplified high frequency fields in the transmission line, first impedance transferring means 10, producing resonant carrier and harmonic frequency fields across the diode 7 in a first portion of the transmission line and second impedance transforming means 11, 12 causing resonance within a second portion of the transmission line selectively to the carrier or to one of its harmonics. The converter may be for amplification, frequency conversion or multiplication of microwave signals. The semi-conductor avalanche diode 7 may be of IMPATT, TRAPATT type or an epitaxial silic or other P-N or step or abrupt junction diode or a P-N-N+ punch through diode. The impedance matching or transforming elements 10, 11, 12 are adjustable axially of the line and are secured by screws 15, 18, 21. Each element 10, 11, 12 consists of a conductive ring surrounding a ring of low-less dielectric material 25, 26, 27 bonded to it at surface 28, 29, 30. The element 10 is positioned #1 from the diode 7 such that aloop (A, Fig. 2, not shown), including the diode 7 and the element 10 is resonant at #F and all of its harmonics. The positions of the elements 11 and 12 at 02, #3 are set so that the diode 7 is in a further loop (B) resonant at N#F such as #H. The element 10 acts as a band stop filter (C 1 L) at frequency #F tending in one adjustment to prevent energy #F from reaching the load. The elements 11, and 12 act as capacitors (C2, C3) and may be adjusted so as to permit flow of currents at frequency #F or of the harmonic signal N#F to a load connected to the line at #H. An alternative means for extracting the output from the converter is by a circulator (at a plane T<SP>1</SP>, Fig. 4, not shown). A circulator may be used in the amplifier mode of the converter to separate the input and amplified output signals.

Title: Improvements relating to photopolymerisable elements and their production
IPC: C08F291/18
Filed: 1959-06-29
Abstract: 864,041. Photopolymerisable elements and process for forming printing relief elements. DU PONT DE NEMOURS & CO., E. 1. June 29, 1959 [July 25, 1958], No. 22309/59. Class 98(2) The elements comprise a support, an anchor layer containing a thermally active initiator; a layer of a photopolymerisable composition comprising a polymeric binder, an ethylenically unsaturated monomer capable of forming a high polymer by photo-initiated polymerisation and an addition polymerisation initiator activatable by actinic light; and between the anchor layer and the layer of photopolymerisable composition a thin barrier layer of polymer obtained by thermal polymerisation of the ethylenically unsaturated monomer in the base of the photopolymerisable layer resulting from the contact of the latter layer with the thermally active initiator of the anchor layer. Exposure and solvent treatment of such elements produces reliefs without passage of the solvent to weaken the bond between the support and the photopolymerisable layer. In Example 1 a photopolymerisable layer or sheet is prepared by casting a solution of N-methoxymethyl polyhexamethylene adipamide as binder, glycerol dimethylacrylate as monomer, and benzoin methyl ether as photoinitiator in hot alcohol on to a glass plate provided with a peripheral dam allowing to evaporate in the dark and removing from the plate, and this is laminated to a dried layer prepared from a methyl ethyl ketone solution of a copolyester prepared from a reaction mixture of ethylene glycol, dimethyl hexahydroterephthalate, dimethyl sebacate and dimethyl terephthalate; together with triethylene glycol diacrylate, methoxyphenol and benzoyl peroxide and coated on to an "alodised" aluminium support, the "alodising" process for which is described. The laminate is pressed between platens heated to 150‹C. to produce the element, and this given a test exposure under an 1800 watt mercury arc and brushed with ethanol to leave the photopolymerised areas firmly adhering to the support. Fourteen further examples and lists of the various materials to be used, including inhibitors, antihalation agents and such like are provided. Specifications 578,079, 711,279, 711,280, 741,294, 741,441, 786,119, 825,795, 826,272, 834,337 and 854,980 are referred to.

Patent GB-224290-A (GB)
Abstract: 224,290. Miles, J. W., and International Time Recording Co., Ltd. Aug. 8, 1923. Workmen's time-recorders.- A card-carriage into which the card is inserted by the workman is positioned by means actuated by the operating- handle so as to be brought into a different predetermined position at each time-recording operation, the means comprising feelers co-operating with holes punched in the card at each operation. The card-carriage 12 is slidably mounted on guides 13, 14, 31 and the card 49 rests on a stop 11 adjusted vertically according to the day of the week. When the card is inserted for the first time it presses aside each of six spring-pressed feelers 36 - - 41 pivoted at 43 to the carriage, thus moving them out of the path of a projection 51 on a bar 35 moved to the right on operation of the handle 17, the bar being connected to the handle by member 33, chain 28 and lever 27 having a pin 26 upon which act a cam 25 turned by linkages 24, 22. The projection 51 thus misses all the feelers and contacts with a member 71 fixed to the carriage so as to move the carriage to the right until the pin 26 reaches a concentric portion of the cam 25, when the carriage will be held stationary for printing and punching. During the movement to the right a fixed stop 55a contacts with the first feeler 36 and moves it out of the path of a punch 55. Further movement of the handle 17 causes a pin 65 fixed to it to reach the bottom of a slot 64 in a lever 63a and move this lever downwards, rocking a shaft 62 having fixed to it an arm 60 which pushes home the punch. The handle 17 is freely mounted on a shaft 20 urged to rotate in a clockwise direction, Figs. 4 and 7, by a spring. Fixed to the shaft 20 is an arm 21<a> carrying a platen 21, and a member 18 pivoted to the handle is adapted to engage a projection 19 on the shaft 20 to rotate the shaft anticlockwise until a roller mounted on the frame contacts with the member 18 to disengage it. The shaft then flies back so that the platen presses the card against clock-controlled type-drums 10, the platen being then withdrawn by another spring. Release of the operating handle withdraws the punch and allows the card-carriage to return to its left-hand position under the action of springs 16, 32. On the next insertion of the card the feeler 36 will take through the hole punched and will thus be in the path of the projection 51 so that when the handle 17 is operated the card-carriage will be moved further to the right, the next feeler 37 will be moved aside by the stop 55a as shown in Fig. 8, a new hole will be punched and printing will take place in a fresh position on the card. The last feeler 41 is connected with a latch 75 engageable with a projection 76 on the handle so as to prevent the handle being operated when this feeler is taking through a hole, the last record for the day having been made, or when there is no card in the machine. If the handle 17 is operated too vigorously a pivoted member 63<b> having teeth 81 riding over a fixed pin 82 will be thrown forwards and engage a pin 83 to prevent further movement until the handle has been released.

Abstract: 301,055. Breusingr, K. Nov. 24, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Multiple machines, mechanical; electric circuit arrangements ;driving.-In order to obtain continuous reproduction of a long composition recorded on a succession of records, the recorded matter at the end of one record is repeated at the commencement of the next and the recording and reproducing apparatus is controlled so that this repeated part is made or reproduced by recorders or reproducers so that collectively the normal energy or output is maintained during the change over, the control being effected electrically by switches opened and closed by a traveling strip with suitable slots. Fig. 1 shows an apparatus with two turntables 7, 8 driven through electromagnetic clutches 9, 10 from a motor 1 and regulated by a metal disc rotated between the poles of an electromagnet 14, which regulator may be driven from the transmission shaft 2 or may regulate the motor directly. As shown, electromagnetic recorders 20, 21 are shown making the repeated parts of two records and supplied with energy through a potentiometer 40, 41 which is moved from the dotted position to the full line position during recording of the repeated matter so that the total operating energy which remains constant is gradually transferred from one recorder to the other. The electromagnetic clutches 9, 10, which drive through springs 35, are controlled through spring-contact switches 15, 16 normally held open by a travelling insulating tape 4 provided with slots 17. During the closure of a contact 26 by a relay 22, the clutch 9 is operative to drive the turntable 7, and towards the end of the record thereon a slot 17 in the strip 4 allows the spring contacts 15 to complete a circuit through relay 19 thereby completing a circuit at 27 to the clutch 10 so that the turntable 8 is now driven. The contact of the potentiometer is now gradually moved so as to transfer the energy or output from the device 20 to the device 21, and this movement may be arranged to break the circuit at 28 or 29 to the clutch driving the completed record so that its turntable comes to rest, or these circuits may be opened manually. The slots 17 are tapered at the end to avoid damage to the strip 4 and additional slots, may be provided to control the amplification, filter, and other devices, or the apparatus as a whole. The strips 4 may wind from one reel to another or may be in the form of endless strips, and the slots may be repeated along the strips. The apparatus may be connected to a kinematograph for synchronous working.
