Patent GB-1233284-A (GB)
IPC: H03B9/14
Filed: 1969-05-07
Abstract: 1,233,284. Bulk effect oscillator device. VARIAN ASSOCIATES. 7 May, 1969 [13 May, 1968], No. 23295/69. Heading H1K. [Also in Division H3] A bulk effect device 1 is connected in series with an inductor 2 and the resistance of a load 3 and the inductor and capacitance of the device series resonate at a selected microwave frequency to cause the bulk effect device to operate in a limited space charge accumulation mode (L.S.A.). When a D.C. or pulsed bias 4 is applied the rise of current is limited by the time constant of the inductor 2 and the resistances of the load 3 and device 1. When the threshold current of the device is reached the capacitance of the device is rapidly charged. In the next quarter cycle the voltage drops and if the energy initially stored in the inductor is great enough to drive the voltage below the threshold the device 1 operates in the L.S.A. mode. The output oscillation is of relaxation form, with approximately half of the cycle below the threshold and the other half a high half sinusoid voltage above threshold. The bulk effect device may be of GaAs and can be mounted between a conductive plug 11 and an inner conductor 8 of a coaxial line 6. The inductor 2 is formed by a reduced diameter portion 8<SP>1</SP> of the inner conductor 8, the outer conductor 12 having enlarged internal diameter portion to further increase the series inductance. Alternatively, the inductor portion 8<SP>1</SP> could be formed by a helical section. The series resonant frequency is preferably above (e.g. by 50%) the desired operating frequency of the oscillator.

An artificial ski-ing surface is formed by separately assembling and then interconnecting flexible elements. Each element before assembly (see Fig. 1) consists of two parallel struts 1, 2 from which project uprights 3, 3a..3n and 4, 4a..4n, which are connected in pairs by crossmembers 5, 5a..5n of rectangular cross-section, bearing protuberances 6 which ultimately afford the ski-ing surface. Each element is assembled by bringing the struts 1, 2 together and securing them (by means of hooks 7 or 7'-Fig. 9, not shown) thereby bringing the pairs of uprights into alignment, and bending each cross-member in the arc of a circle. Then the elements (A, C) are interconnected (see Fig. 6) by positioning them so that the rings 9 of the cross-members of one element are situated over the rings 8 of the cross-members of the adjacent element and inserting pins 11. The structure is completed by interposing other elements B in overlapping relation to A and C. The connectors 8, 9 and 11 may be dispensed with, spurs (13, 14, Fig. 8, not shown) formed on the protuberances instead effecting interconnection of elements.

A collapsible cargo container for use in aircraft has side walls 22, 24 and 28, 30 which may be folded down over a base 12 and which, when erected, are positively coupled by sliding slatted walls 18 and 20. The slatted walls and their tracks 45 in the side walls have co-operating flanges and slots, Figs. 6-8 (not shown), to provide the coupling action. Alternatively, rollers on the slatted walls may engage undercut recesses in the side walls. A ridge piece 64 is detachably located between the side walls but plays no part in coupling them. The slatted walls may be partially or wholly withdrawn over the ridge piece for loading or collapsing the container. When wholly withdrawn, the slatted walls may be passed through interruptions 56 in the tracks for storage as shown in Fig. 3. The side walls are retained in their erected condition by releasable fastenings 36 and 66, 70. The slats of the walls 18 and 20 are formed of sheet material and are linked by hinges, Fig. 5 (not shown ). The hinges are covered by curved overlapping parts of the slats, which parts are centred on the hinge axes and provide a weather seal.

The liquor is delivered from reservoir tank 14 to the processing tank 13 by pump 15. The liquor percolates through the layer of wool which is 2-3 mm. thick and moving at about 150 ft. per minute. The nipping devices 17 are wedge shaped and designed to produce a undirectional flow of liquor through the wool. After passing through the wool the liquor maintains a level on the moving wool layer before the wool enters the processing tank 13 and passes back into tank 14. After leaving the processing tank, excess liquor is removed from the wool by squeeze rollers or is partially displaced by liquor pumped from the next processing stage by the employment of wedge nips 23.

Abstract: 1324502 Cold accumulators BRITISH OXYGEN CO Ltd 19 Aug 1970 [19 Aug 1969] 41285/69 Heading F4H A closed cycle refrigeration apparatus includes a cold accumulator having a packing material containing one or more anhydrous halides of divalent iron, nickel or cobalt. The packing material, having a particle size of at least 100 microns, is preferably arranged in layers, the material in each layer having a higher thermal capacity at successively lower temperatures. As shown, an upper layer 36 of lead shot occupies 50% of the bed; a middle layer 38 of encapsulated ferrous bromide occupies 25%; and a bottom layer 40 of encapsulated ferrous iodide also occupies 25% of the bed. In operation, with piston 2 at its lowest position, the valve 24 allows high pressure gas to pass from conduit 20 into conduit 28. Part of the high pressure gas passes through conduit 30 into chamber 16, raising the pressure in chamber 16, and the remainder passes through the regenerator 32 absorbing cold stored in the regenerator 32 from a previous cycle and then through conduit 34 to chamber 18. The valve 24 is then rotated to a position in which the chamber 14 and conduit 26 are connected to conduit 22. Consequently the piston moves upwardly, gas from chamber 16 passing through the regenerator 32 via conduits 30 and 34 to chamber 18. The valve 24 is next rotated to a position in which the conduit 28 is connected to conduit 22. Gas from chambers 16 and 18 expands to the outlet pressure and cools. The valve 24 is finally rotated, conduit 20 is connected to conduit 26, the conduit 28 remaining connected to conduit 22. The piston 2 moves downwardly, pushing further cold gas from 18 through the regenerator 32.
