Title: Steam generator
IPC: F24J3/00
Filed: 1973-11-22
Abstract: 1441980 Steam generator SONAQUA Inc 22 Nov 1973 [29 Jan 1973] 54329/73 Heading F4A A steam generator 10 comprises a rotor 16 mounted in a stationary housing 11, the rotor and housing defining a chamber comprising many passageways extending in different directions, at least one passageway being closed at one end, and at least one passageway having a radial component, so that when water is delivered to the chamber and the rotor is rotated water is flung outwards by centrifugal force, causing a vacuum in the or each closed passageway, which pulls the water back, giving rise to a series of shock waves ("water hammer") the energy of which raises the temperature of the water and produces steam. Water enters the housing at 17 and follows arrows 56-61 and 67-69 through the passageways of the chamber and arrows 62-66 through annular chambers 50-52 formed by coaxial tubes 33,37, 43 in superstructure 30, steam being removed through tube 37 (arrow 70) and water returning (arrow 71). The passageways are constituted by the upper ends of frusto-conical passages 21 in the rotor and by the communicating upper ends of the annular chambers 51, 52, or, Fig. 5, (not shown) by vertical paraxial passages (98) in the rotor.

Title: Optical System for Guiding a Projectile
IPC: H01S3/00
Filed: 1966-12-05
Abstract: 1,177,950. Photo-electric missile guidance. THOMSON-CSF. 5 Dec., 1966 [6 Dec., 1965], No. 54427/66. Heading H4D. In an optical beam-rider system for guiding a missile from a launching base to a target the launching base comprises sighting means having an optical axis aimed at the target and laser means generating fan-shaped modulated light beams which cross each other and are deflected across the optical axis. In the missile the modulated energy is sensed and controls a rudder. The beam deflections are according to a programme starting from the moment of missile launching. In one embodiment, Figs. 1, 2, a laser 1 produces a continuous or intermittent infra-red beam which is passed through an amplitude modulator consisting of crossed polarizers 2a, 3a with an interposed birefringent medium 4a; the amplitude-modulated beam then passes through an anamorphotic system of cylindrical lenses 5a, 6a to give a fan-shaped beam, the divergence α being controlled by varying the distance between the lenses and the beam orientation with respect to axis oz is adjustable by pivoting the lens assembly. The missile 10 proceeds inside a corridor, centred on the line of sight, whose walls are formed by beams 7a, 7b, 7c, 7d, four modulators 4a ... 4d &c. being provided. A programmer 11 is started when the missile is launched and actuates motors 8a, 9a such that the beams form a corridor, not exceeding the target's dimensions, around the missile. In the missile a light filter 16 precedes a photo-electric element 17 connected to a receiver 18 having outputs a, b, c, d corresponding to the detection of beams 7a ... 7d, those outputs (of respective modulation frequencies f a  ... fd) feeding into a known system 19 including a gyroscope and a computer which gives commands M, N for trajectory correction by means of rudders, 23, 24. In another embodiment a proportional control is afforded by two orthogonal laser beams sweeping the "guidance volume," utilizing vibrating mirrors; the beams are amplitude-modulated and are frequency-modulated in synchronism with their sweeps, Figs. 3, 4 (neither shown). Frequency-modulation may be replaced by pulse-width modulation.

Title: A circuit arrangement for the presentation of waveforms on viewing screens with raster deflection
IPC: G09G1/16
Filed: 1970-11-19
Abstract: 1300484 Cathode-ray tube display INTERNATIONAL STANDARD ELECTRIC CORP 19 Nov 1970 [27 Nov 1969] 54993/70 Heading H4T An arrangement for generating bright-up signals for a mixed display of graphs and alphanumeric characters (for example for data on hospital patients) for a T.V. type raster scan comprises a memory 1 and register 3 which receives numerical and character data from a computer, a memory 5 and symbol generator 7 for producing under control of unit 4 the bright-up signals for the characters to be displaced, and a system (enclosed in broken lines) for generating the graphical bright-up pulses for adding to the character signals in mixer 8. As described each graph is specified by eighty points spaced equally along the X (line) scan, the Y values of these points each being represented by a 7-bit code so that 80 7-bit words are supplied to and held in memory 6 for as many horizontal line scans as are required for the graphical display of this data (a number of graphs may be displayed one under another). These 7-bit words are read out at the appropriate point of each scan and held in calculator 9, where an interpolation between successive ordinate values is carried out. This is done by calculating the increment by subtraction, dividing by eight (by a 3-bit shift) and adding this eighth eight times as the line scan travels over one-eightieth of the graph length. The result of this calculation is continuously compared with the vertical position derived from the line scan count to produce bright-up pulses at equality; or when the inequality changes. This process continues until the scan reaches an area for display of another graph, when new ordinate data replaces that held in memory 6.  In a modification increment of the ordinate values are supplied from the computer instead of their absolute values, these increments being devided by eight and accumulated in the manner described above.

Title: Fluid Pressure Control Valve
IPC: B60T13/14
Filed: 1967-12-14
Abstract: 1,158,039. Valves; hydraulic braking systems. BENDIX CORP. 14 Dec., 1967 [22 Dec., 1966], No. 56910/67. Headings F2F and F2V. A valve comprises a tubular poppet with an annular frusto-conical surface co-operating with a valve seat of annular elastomeric frusto-conical surface inclined at a greater angle to the axis of the poppet than is the surface of the poppet. Such a valve is described as used in a vehicle dual hydraulic braking system. In Fig. 1, depression of the brake pedal (not shown) moves a rod 62 which via a plunger 60 and pivoted link 64 operates hollow valve members 52. Hydraulic fluid from a pump 14 and accumulators 16/18 entering at ports 20/22 can then no longer pass to exit port 29 since the end of the poppet 38 seals the inside of the hollow members 52. Further movement of the pedal then unseats the poppet 38 from a member 42, allowing the pressure in chamber 102 to equal that of the high-pressure fluid in chamber 84. Thence the fluid passes down the inside of poppet 38 to the brake members 28/30, and also acts on a sealing disc 48 to provide feel for the operator. If one side of the dual system should fail, the cam surfaces 66/68 allow the necessary travel of the valve member 52 on the good side while allowing greater travel on the failed side. In a modification (Fig. 3, not shown) separate pumps and reservoirs are provided for the two sides and each has a separate exit port back to its reservoir. In addition, residual-pressure check-valves (86, 88) are provided in the outlets to the brake members. Valve construction (Fig. 2).-The surface 72 of the hollow poppet 38 co-operates with a plastic valve face 74 which has a greater inclination to the axis than has the surface 72. When the valve is closed, the seating area corresponds with the diameter 82 of the rear of the poppet since the face 74 deforms under the influence of a spring 40 (Fig. 1). Thus the back pressure in chamber 102 tends to keep the valve closed.

A metal sheet 1, Fig. 1, forming the cathode of a gas discharge indicator is stamped, etched or cut by laser, ultrasonic means, electro-forming or electrical discharge means to produce a stencil-like body having elements 6 therein connected to the remainder of the sheet by bridges 4, 5. A number of connector pins 8, Fig. 3, are sealed in to extend from a glass plate 9 and the sheet 1 is aligned with the plate 9 by rods 28 engaging holes 31 so that each pin 8 engages an element 6. A lower electrode 27 is then applied to a pin 8 and an upper electrode 23 is applied to the appropriate element 6 and current is passed to weld the pin and element. After all the elements 6 are similarly welded and possibly also triangular or U-shaped elements separate from the sheet are welded to pins, the electrode 27 is applied to a pin and the electrode 23 is applied to the sheet 1 so that current flows through one or more tabs and melts them. When all the tabs are melted the remainder of the sheet is discarded. For mass production the plate 9 is placed in a jig, a sheet of conducting material beneath the jig makes electrical contact with the pins and is connected to one side of a welding source, a further sheet of conducting material carrying a plurality of electrodes aligned with the elements 6 and carrying a plurality of electrodes insulated from the further sheet and aligned with parts of the sheet 1 is arranged above the sheet 1, the other side of the welding source being connected by a switch either to the further sheet or to the insulated electrodes. Instead of electric welding and severing, direct heat or laser beam may be used. Both the anode and the cathode of the gas tube may be co-planar, the discard pieces within the sheet then constituting the anode and possibly being fixed to pins by the method described for the cathode elements.
