Title: Valve with modular housing
IPC: F15B21/00
Filed: 1972-11-22
Abstract: 1414659 Valves CLIPPARD INSTRUMENT LABORATORY Inc 22 Nov 1972 [10 Dec 1971] 54116/72 Heading F2V [Also in Division G3] A valve construction comprises a standardized "quick mount" hollow tubular housing which is provided with passageways 33 in the wall of the housing which connect the external ports 59 of a valve mechanism inserted in the housing via ports 48 to passages 14 in a base 10. The ports 48 are made as desired. The valve comprises various standardized elements which are stacked inside the housing and held in position by a cap 20 provided with the housing. Various types of valves can be assembled but all ports of the valves open into a respective annular groove in the external surface of the valve. A port 48 is made at the same longitudinal distance to the required passage by cutting (prior to insertion of the valve) for example by a rotary cutter. The housing has a keyed projection 44 to effect proper orientation of passageways relative to the base. The valve shown in Fig. 4 is a piloted four-way valve. Fig. 5 shows a shuttle valve 81 and a check valve 82, in this case completely separate. Other forms of shuttle valve and piloted multiway valves are described; in one of the latter the cap is provided with a transparent window so that the position of the spool is visible while another has a passage which is ported twice at different longitudinal positions with a flow restrictor therebetween. In Fig. 7 the cap is provided with a knob 142 for an adjustable needle valve 140 which is provided in the port 141 of a time delay flow control valve 126. The valve 126 permits free flow from passage 145, past check valve 138, to passage 148 but restricts flow in the opposite direction. This fluid is bled slowly past the needle valve to passage 45 which is connected to the volume chamber 156 and this delayed pressure build up is used to retard the operation of a member actuated by the pressure in passage 145. The invention can also be used as a fluidic valve as shown in Fig. 9 when a plug provides the fluidic circuit of an amplifier with similar connection to the housing passages as previously described.

Abstract: 1279084 Reactors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 3 Nov 1969 [15 Nov 1968] 54439/68 Heading G6C A liquid metal (e.g. sodium) cooled fast breeder reactor has a core configuration which includes a central cylindrical breeder region, a first fissile region which completely embraces the central breeder region, a second fissile region at least partially surrounding the first fissile region with axial and radial clearance, an inner breeder region occupying this clearance, and an outer breeder region extending both axially and radially from the outer boundary of the second fissile region to the cylindrical core boundary. In a preferred construction, shown in Fig. 2, the second fissile region only partially surrounds the first fissile region, the " corner " fissile portions of a wholly surrounding fissile region being replaced by breeder material. The annular region between the first and second fissile regions, i.e. the region bounded on the inside by lines 13, 13<SP>1</SP> and on the outside by lines 14, 14<SP>1</SP>, is therefore entirely breeder and of full core height. Because of the lower heat rating of breeder pins, it may comprise fuel pins of greater diameter than those which include fissile material, thus enabling a higher breeder/ structural material ratio to be achieved. The radially outermost region comprises similar fuel pins. Preferably, the fissile material is mixed U and Pu oxides, and the breeder material is UC.

Abstract: 1278976 Ink jet printers RECOGNITION EQUIPMENT Inc 10 Nov 1969 [10 Feb 1969] 54825/69 Heading G4H In an electrostatically deflected ink jet printer including an ink drop forming unit 10a, a servo loop is provided for adjusting the phase of a charging voltage applied to the ink drops to ensure synchronism between the instant of formation of the drops and the phase of the drop charging voltage. A high-frequency sine wave generator 331, controlled by a system clock 316 energizes a piezo-electric crystal 105 which vibrates a nozzle 104 to form the ink drops. The drops pass between charging plates 109 and are deflected in proportion to their charge by plates 110, 111 before striking a moving document 100 on which a series of eight drops forms a printed bar 114. The plates 109 are connected to a stair step voltage generator 323 via a " write " amplifier 326 gated by signals from a computer 336 having a data input from a tape 343. To ensure that each drop receives a charge corresponding to the successive levels of the stair step voltage and not to a voltage between these levels, a calibration cycle is included between the printing of successive documents. During this calibration period the amplifier 326 is turned off and a gated amplifier 327 is turned on by the computer 336. The amplifier 327 is connected to a ramp function generator 335 which charges the drops, the drops being collected by a catcher 112. The voltage on the catcher and a reference voltage 304 are fed to a difference voltage amplifier 302 in a voltage comparator or phase detector 301 having " up " and " down " phase outputs 307, 308. These outputs are connected to an accumulator 309 controlled by a pulse from a clock 310, the accumulator being connected to a D/A converter 313 and a phase shifter 315. A counter 321 to which the phase shifter is connected determines the number of drops in each bar. The phase shifter controls the phase delay between the charging voltage on the plates 109 and the crystal excitation voltage output of the generator 331.

Abstract: 1437503 High voltage step-wave generators THOMSON-CSF 27 Nov 1973 [28 Nov 1972] 54992/73 Heading H3T To generate a stepped high voltage (Fig. 4, not shown) a capacitor C11, Fig. 3, is held charged to an initial level OR by a source 1 through an inductance L1, and is then successively charged to higher levels UJ, UV by repeatedly charging a capacitor C2 and discharging it through a winding L3 coupled to L1. The source 1 is of the order of 5 kv and the source (not shown) charging C2 through an inductor L2 is of the order 150 v, the resulting stepped voltage being used to operate a polychromatic cathode-ray tube (not shown). The repeated chargings of C2 are effected by a transistor I2 controlled by a circuit 20, and its dischargings by a thryistor I3. At the end of the third step (UV) C11 is discharged by an arrangement of thyristors I1a to I1p which are protected from overload by avalanche diodes D1a to Dlp and are controlled by a transformer T2 receiving a control signal S5. A further capacitor C3 is repeatedly charged via I4 and discharged by I5 through a further winding L5 to "top-up" the charge on C1. A feedback control circuit R2, R3, 25, 26 provides output voltage regulation.

Abstract: 1,066,978. Securing labels, shoots. STEPHENS INDUSTRIES Inc. Dec. 29, 1965 [Dec. 31, 1964], No. 55047/65. Headings B8F and B8S. [Also in Divisions D1 and F2] A label is secured to an article by apparatus (see Division D1) adapted to pass a length of flexible filamentary thermoplastic material, issuing from a supply thereof, through the label and article, to sever said length from the supply, and to deform the protruding ends of the cut length by heating. Labels 26, stacked in a hopper 48, are fed consecutively on to ledges 28 flanking a V-shaped groove 30, to be secured thereat to fabric supported above groove 30 by wire arms 84. The labels in hopper 48 are supported by the front end of a slidable bar 54, the rear end of which is rigid with the piston-rod 60 of a pneumatic cylinder 62. Pressure is normally applied to the latter for positioning bar 54 to the left, when a shoulder (66), Fig. 7, thereon abuts the lowermost label. A reversal of pressure thereby shifts said label on to ledges (68), and, on retraction of bar 54, said label abuts a shoulder (74) while the now lowermost label abuts shoulder (66). In operation, a plate 96 on a lever 94 is manually depressed to actuate a microswitch. Pressure to cylinder 62 is thereby reversed, whereby bar 54 moves forward to transfer a label from the ledges (68) to the ledges 28.

Abstract: 1,151,138. Pressure treatment for continuous length sheet material. WAKAYAMA IRON WORKS Ltd. and HAMANO SENI KOGYO K.K. 9 Dec., 1966 [20 Dec., 1965], No. 55309/66. Heading D1L. An apparatus for the sub- or super-atmospheric treatment of continuous length sheet like material has a liquid seal 4 at the inlet for the material and the material is hermetically clasped between a pair of moving endless bands 1 and 1' as it passes through the liquid, the bands passing over return rollers 3" immediately adjacent the material outlet side of the liquid seal so that the bands barely pass into the treatment zone 5. The liquid of the seal is a low fused molten metal. The hermetic sealing effect between the belts 1 and the material 2 is enhanced by installing air suction means between the belts immediately before they are brought into adherence by rollers 3'. The perimetric edges of the bands may be composed of magnetic rubber, or alternatively co-operating grooves and ridges may be provided on the bands 1 and 1'. The bands are made of a material which can withstand the molten metal, e.g. rubber or synthetic resins. The outlet of the treatment zone 5 can be provided with a similar sealing arrangement, or alternatively the same liquid seal can act as inlet and outlet for the material (Fig. 3, not shown). Where the apparatus is concerned with dyeing a dye bath 8 may be arranged externally (Fig. 1) or internally of the apparatus. A single batch or double batch roller can be provided within the treatment chamber (Fig. 5). The sheet can be reciprocatively treated by winding and unwinding means disposed externally of the apparatus.

Abstract: 1401109 Camera mounting ASAHI KOGAKU KOGYO KK 29 Nov 1973 [30 Nov 1972] 55463/73 Heading G2A A camera mounting assembly comprises a stationary member 32, a movable member 20 pivotable relative thereto, one member having a number of position detecting means and the other a number of position setting means, one of the sets of means being externally adjustable, so that photographing conditions can be pre-set, with a corresponding control output when the two sets of means are in a predetermined position. As shown, a camera 19 having a pre-set focusing lens barrel 19' is carried by a support 18 pivotally mounted on shaft 20. Discs 23, 24 and 25 are rotatably mounted on shaft 20, and can be secured in any position by respective clamps 26, 27, 28. A base member 32 is mounted on a tripod 33, and shaft 20 can be secured to member 32 in any given position by a screw 34. The upper part of member 32 is formed as a cover 35 having windows 36, 37, 38 through which clamps 26, 27, 28 extend, and adjacent the windows are indicia 39, 40 and 41. Each disc has a notched portion 29 (see also Fig.4 not shown) which, when the disc is rotated to the appropriate position, co-operates with a switch (such as 42 or 43). A potentiometer 46, which is associated with switch 42, and also with a particular focal distance, can be set at a predetermined value which corresponds to this distance. When the notch 29 of disc 23 engages with the switch 42, a circuit is completed which automatically adjusts the focus of the lens to that distance. The position of disc 23 is so fixed, by clamp 26, that notch 29 and switch 42 will be aligned only when the camera is pointing in a particular direction, e.g. at the object to be photographed. Thus only when the camera is pointing in the right direction will the focus be automatically adjusted to the predetermined value. In the arrangement shown, there are three potentiometers, 46, 47, 48, corresponding to the three discs 23, 24, 25, so that three different focal distance settings are available.  Other photographic conditions, such as exposure values or diaphragm settings, may be controlled in the same way.

Abstract: 1,141,490. High voltage switches; actuation of switches. S. & C. ELECTRIC CO. 13 Dec., 1966 [20 Dec., 1965], No. 55701/66. Heading H1N. In a high voltage circuit breaker two rectilinearly movable series connected contacts 47 are operated by a rotary double armed lever 66 driven by a spring. Two series connected interrupter units 32, 33 each housing two series connected main breaks 45 and two series connected auxiliary breaks 53 in parallel are mounted on opposite sides of a mechanism housing 34. The movable contacts 47, 55 are coupled by rods 49, 59 and links 62, 76, 77 to a pair of double armed levers 66, 80 loosely mounted on a shaft 67 attached to a rotatable insulator 13 which also supports the housing 34. Initial rotation of insulator 13 anticlockwise (from above) causes an arm 137 to release a roller latch (127) (Fig. 10, not shown) allowing lever 66 to rotate clockwise under springs 102, 103. If the contacts stick further movement of arm 137 causes positive actuation of lever 66. The second lever 80 is coupled to lever 66 by a coiled torsion spring (83) (Fig. 5, not shown), which is stressed by the initial rotation of lever 66, lever 80 being held by a roller latch (171) (Fig. 11, not shown) until the main contacts have separated. On further rotation of lever 66 latch (171) is released and an abutment on lever 66 strikes lever 80 causing rapid opening of contacts 53. Shock absorbing buffers 186 (187) stop the lever 66, 80. Continued rotation of insulator 13 opens a series isolator (28, 29) (Figs. 1, 2, not shown). Towards the end of the rotation, an abutment 150 on arm 137 drives lever 66 back to the contacts closed position, restressing springs 102, 103 and resetting the roller latch (127). Lever 66 is arranged to rotate an indicator drum visible at a window 207. Springs 102, 103 are adjustable by a toothed disc 104. The interrupter units which may be as described in Specification 966,110 are sealed and contain SF 6 , the auxiliary breaks having blast action. The insulator 13 as well as other fixed supporting insulators (14, 15) carry voltage grading rings 37, 38, 40, 41.

Abstract: 1474637 Measuring parameters of networks L P RUSSIN 27 Dec 1974 55971/74 Heading G1U A device for measuring the transfer parameters, e.g. amplitude ratio; phase shift; response time; output frequency, of a network comprises a source of oscillations connected to the network under test, N.U.T., to a variable phase shifter, an indicator connected to the output of a difference amplifier whose first input is connected to the phase shifter and a changeover switch connecting the source output to phase shifter input and the output of the N.U.T. to the second input of the amplifier or vice versa. In Fig. 2 the N.U.T. is a control circuit 2. The test operation is as follows:- (a) switch 6 set to positions 8, 58, 59 and capacitor 27 in phase shifter 5 set to zero-, (b) indicator 4 reading taken; (c) switch 6 set to 7, 59, 60; (d) resistor R34 in one input to difference amplifiers 3, comprising inverter 32 and adder 33, adjusted until indicator 4 reads the same as in (b), the channel gains are now equalized and the value of R34 indicates the ratio of input to output amplitudes; (e) switch 6 set to 7, 8, 59 and capacitor 27 adjusted until indicator 4 is a minimum (f) the phase shift across the circuit 2 is then calculated from the values in phase shifter 5; if the phase-shift is greater than - 180 degrees, the channels are reversed by setting switch 6 to positions 9, 10, 60 at step (e). To measure response time a squarewave generator is used for source 1 in place of a sine source. The frequency of the source is measured by using a differtiating circuit of known frequency dependence for the N.U.T. 2. The network may also comprise inductance or capacitance combined with resistance, Figs. 3, 5 (not shown), whose values can be calculated from the aforementioned parameters. To improve noise response, filters may be added between the amplifier 3 and indicator 4. This output may also be detected and displayed on a D.C. meter, Figs. 6-8 (not shown).
