Title: Improvements in or relating to a lock arrangement for pressure vessels
Inventor: LEES NORMAN EDWIN
IPC: F16J13/08
Filed: 1963-12-31
Abstract: 992,686. Latches. BENHAM & SONS Ltd. Dec. 31, 1963, No. 51300/63. Heading E2A. [Also in Division F2] In a lock arrangement-for a pressure vessel having means for preventing the door of the vessel from being fully opened until pressure on both sides of the door are equalized, first and second elements are adapted to be pivoted respectively on two relatively movable parts of the vessel such that relative movement of the parts in one direction causes the elements to engage one another whereby so inhibit relative movement of the parts in the other direction. As shown, a spring loaded catchplate 12 pivotally mounted on a wall 10 of a pressure vessel, includes an aperture 17 which in the closed and fastened position of a door 11, co-operates with a projection 29 on an arm 20 which is pivoted about an arm 21 within the door. The arrangement is such that as the arm 20 is moved about the pivot 21 by a hand wheel 26 to free the projection 29 from the edge of the aperture 17, a seal 28 between the door and the wall 10 is broken thereby to relieve the pressure within the vessel. The catchplate 12 may then be swung outwardly about the pivot 13 to allow the door 11 to be opened. Upon re-closure of the door, the arm 20 snaps past the surface 33 of the catchplate 12 whereafter the handle 26 may be operated to fasten and seal the door.

Title: Method of generating modulated light or infrared radiation
IPC: H04B10/50
Filed: 1964-12-18
Abstract: 1,035,730. Light modulation. M. GRUNDIG. Dec. 18, 1964 [Dec. 19, 1963], No. 51565/64. Heading H4F. The light or infra-red radiation generated by an electrically heated incandescent radiator element 1 is modulated by applying a sinusoidal carrier wave 4, amplitude modulated by a signal to be transmitted, to a transistor amplifier 3 connected by way of an impedancematching transformer 2 to the radiator element. Because of the frequency doubling of the carrierfrequency oscillation the frequency of the carrier wave is arranged to be greater than half the maximum signal frequency to be transmitted so that variations in the radiation which result from the fact that excitation is effected by an alternating current are of a frequency exceeding the highest frequency of the signal transmitted. For speech transmission the frequency of the carrier wave is above the audible range, e.g. 7 kc/s. The working point of the radiator is set by adjusting the gain of transistor 3, i.e. by adjusting the resistor in the emitter lead, and thus altering the mean amplitude of the carrier wave. Because of the thermal inertia of radiator 1 the radiation emitted with an unmodulated carrier is constant or modulated only by frequencies outside the signal frequency spectrum.

Title: Process for the manufacture of cellular structures of synthetic macromolecular substances with decreased inflammability
Inventor: RAAMSDONK GERRIT WOUTER VAN
IPC: C08J9/00
Filed: 1966-11-29
Abstract: Foams of decreased inflammability are produced by foaming or sintering mixtures of combustible synthetic macromolecular substances, or precursors thereof, with elemental sulphur so that at least 2% by weight of sulphur is retained in a surface layer 1 mm. deep, irrespective of the elemental sulphur content in other parts of the cellular structure.  The sulphur is preferably present in this layer in proportions between 5 and 35% by weight, and it may be evenly distributed up to a maximum of 50% in the mixture from which the foam is prepared.  The macromolecular substance may be polystyrene, polyurethane, a polyolefin, a polyacetal, a polyether or a polyester.  Examples include the addition of sulphur to prefoamed polystyrene beads in a mould and subsequent expansion, and the suspension of sulphur in a polyhydric alcohol and subsequent reaction with a polyisocyanate to produce a polyurethane foam.  Other flame retardants may also be incorporated, e.g. organic halogen compounds and organic phosphorus compounds, especially tris (2,3-dibromopropyl) phosphate, and antimony compounds.  The sulphur may be dispersed in a plasticizer before addition, or may be mixed with or adsorbed on an inert material, e.g. clay or kieselguhr, or may be dissolved in a solvent, e.g. CS2 or naphthalene, or may be coated with substances such as starch, polyvinyl alcohol and polyvinyl acetate, or mixed with molten polystyrene, solidified and ground.

Title: Tuner for microwave crossed-field tubes

Filed: 1970-11-12
Abstract: 1327275 Magnetrons VARIAN ASSOCIATES 12 Nov 1970 [12 Nov 1969] 53962/70 Heading H1D In a microwave tube having a cathode and a spaced anode with a microwave circuit portion facing the cathode in which the anode-cathode space is permeated with crossed electric and magnetic fields, the circuit portion is tuned by means of a translatable composite disc structure including a dielectric member sandwiched between two conducting members 14 and 15. In the magnetron arrangement shown the tuner comprises annular copper plates separated by an annular alumina ceramic dielectric with the area of the lower metal annulus 15 facing the anode less than the area of annulus 14 facing the anode so as to obtain substantially linear tuning characteristics. Conducting vanes 7 separate microwave resonators in the anode structure and alternate resonators are shortened in radial extent than the intervening resonators by providing conducting back walls 8 to define a rising-sun type magnetron. Axially the anode resonators open into spaces 9 and the tuner is disposed in the upper space with the lower conducting member 15 in register with the back walls 8. The tuner is attached to circumferentially disposed rods 26 which are slidably mounted in channels through a soft iron magnetic polepiece 28 and are attached to a spider 25 provided at one end of an actuating rod 29. A second spider 35 on rod 29 is attached to the tube envelope by a vacuum-tight bellows 31, and a spring 33 engages a flange portion 34 of the housing member 32 to resiliently bear on the spider 35, the rod being held in position by an external tuning knob 38 which engages the top of the rod by means of a screw thread 37 and abuts the housing member 32. The substantially linear tuning characteristic in which the frequency change is approximately proportional to the linear displacement of the tuner allows temperature compensation by choice of coefficients of thermal expansion of the materials used for the polepiece, housing member 32 and tuning rod 29.

The film web 3 formed on the calender 1 is drawn from the discharge roll of the calender immediately or almost immediately into the inlet end of the stretching device 2 in which it is stretched transversely by means of clip chains 4 in the usual manner. Two or more feed or tempering rolls 5 are interposed between the calender and the stretching device being immediately adjacent to the last or discharge roll of the calender and the inlet end of the stretching device. The rolls 5 are adapted to be maintained automatically within a predetermined temperature range and the delivery roll 6 of the stretching device is adapted to be cooled.

The beam carries a vane 20 in a tank 19 of viscous fluid to provide damping. The output signal from differential transformer 8 is periodically gated to switch on a servomotor in the appropriate direction for a predetermined time whenever the position of the beam indicates that the predetermind force has over or under straightened the blade; the servomotor adjusts a resistor in series with a motor driving the hammer of a machine which bends the blades in advance of the measuring station Fig. 2 (not shown) thereby  keeping the force exerted by the hammer, and hence the resulting curvature, substantially constant. The sequencing of the bending and measuring operations is controlled by a variable frequency clock pulse generator Fig. 5 (not shown). The arrangement produces blades for relay contacts continuously from a coil of stock material.
