Title: Gas-cushion vehicles
Inventor: DYKE R
IPC: B60V1/00
Filed: 1969-01-08
Abstract: 1300751 Gas cushion vehicle VOSP ER THORNYCROFT Ltd 2 Jan 1970 [8 Jan 1969] 1172/69 Heading B7K [Also in Division F2] A gas-cushion vehicle is provided with valve means, disposed in a duct 10 supplying the cushion, which comprise at least a pair, as shown two rows, of sealing members 12 of flexible material, which may be U-shaped in plan (c.f. Fig. 4, not shown) and triangular in elevation. These are attached by cords 13 to pins 15 on the walls of the duct 10 and by cords 16 to a bar 19 traversing the duct. When a lift fan supplying pressurised gas to the cushion is operating, the segments 12, in the position shown by full lines, offer little or no resistance to the flow of gas which is in the direction A. Should the lift fan fail, however, gas will begin to flow in the opposite direction and the segments will take up the position shown in dotted lines, the closed ends 20 of the U-shapes being now at 20a, forming a seal across the duct to minimize the reverse gas flow.

Title: Improvements in or relating to temperature responsive actuating elements
IPC: G01K1/20
Filed: 1957-01-11
Abstract: 833,696. Temperature-responsive actuating elements. NICKEL. E. Jan. 11. 1957 [Jan. 14, 1956], No. 1181/57. Class 64(2) To compensate for ambient temperature changes, two bellows 3, 5 are connected by a bridge or frame 4, one end 12 of one of the bellows 3 being the only fixed end. Then the corresponding but free end of the other bellows 5 moves according to the temperature of the pilot bulb 1 of the fixed bellows 3 or, if the bellows 5 and its capillary tube 6 have an associated pilot bulb 7, it moves according to the temperature difference between the two pilot bulbs 1 and 7. This movement of the bellows 5 is used in a thermometer or thermostat. Changes in temperature of the ambient of the bellows 3, 5 and their capillary tubes 2, 6 cause equal and opposite expansion of the bellows so that there is no movement of the compensating bellows 5 resulting from such change. The bellows may be mounted on the same axis, as in Fig. 2, the corresponding free ends of the bellows being interconnected by a frame 4. Guide rods at the ends of the free bellows 5 slide in guides 10. The capillary tube 6 is flexible to allow the free bellows 5 to move.

As shown, the invention is applied to a power lift mechanism having its links 6 carrying a towbar 7 to which is connected a single axled trailer 10. The part a of the strut is formed of two vertically displaced members 14 carrying at their front end a member 18 adapted to be pivoted to the tractor 5 and secured together at their rear end by rivets 17, portions 21, 22 of the rear part a<SP>1</SP> of the strut being received between the members 14. The members 14 are apertured to receive a locking pin 13 which may pass between the parts 21, 22 in order to lock the strut. Parts 19 of the part a<SP>1</SP> of the strut diverge rearwardly to be connected to the rear portions of the links 6, one of the parts 19 being of adjustable length as shown at 23, 24.

A scale on a skirt o on the sleeve is now read against a mask on the body a. The sleeve is now screwed into the block and the tension on the wire transferred to the block this point being indicated when the pin h is just free in the eye. The scale on the part o is again read and this is a measure of the tension.

Abstract: 556,003. Coloured filter and antihalation layers. GEVAERT, Ltd., (Moen, L.). Jan. 30, 1942, No. 1296. [Class 98 (ii)] A coloured photographic filter or antihalation layer comprises a binder containing the free base of a basic dye of the diphenylketone-imine type in which the imino hydrogen has been substituted by an alkyl, aryl, or acyl group. The methyl, phenyl, o- and p-tolyl, α-naphthyl or acetyl substituted Auramines may be used. The free bases may be precipitated with an alkali solution (e.g. NaOH solution) and the filtered and washed precipitates dissolved in an organic solvent which is then added to a gelatin solution and coated to form a coloured filter or antihalation layer. Alternatively, the dye salt may be added to a gelatin solution (an organic solvent, e.g. methyl alcohol being added if necessary), the chemically equivalent amount of alkali added, and the gelatin solution set, shredded, washed, remelted, and coated. The filter may act solely as a taking filter or both as a taking and a re-exposure filter. Decolorization is effected by bathing in a dilute or weak acid bath. Addition of a bisulphate may facilitate decolourization. In multilayer material, a filter layer according to the invention may be coated on each side of the middle emulsion layer. Specifications 483,020, 483,035, 498,749 and 541,335 are referred to.

Abstract: 902,351. Valve gating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 17, 1959 [Jan. 17, 1958], No. 1737/58. Class 40 (6). A gating circuit comprises a valve having the waveform to be gated applied to the grid and means for rendering the valve temporarily conductive to develop an output voltage proportional to the instaneous value of the waveform and a compensating circuit to which the waveform is applied and which applies compensating signals to the output of the gating valve or to a subsequent stage to compensate for distortion of the gated waveform due to capacitance coupling between input and output of the gating valve. As shown, the gating valve V1 is normally biased off from supply B but is rendered conductive by gating pulses applied to the cathode. The waveform to be sampled is applied to the grids of V1 and V2, the latter valve providing an inverse waveform via capacitor C1 to minimize the waveform transmitted via the grid-anode capacitance of V1 when non-conductive. Capacitor C1 should have the same value as the grid anode capacitance of the valve. The bandwidth of V2 should be greater than that of the anode circuit of V1.

[Class 37] [Also in Group XXXVII] In a direct-reading ohmmeter of the crossedcoil type the polepieces 11, 12, Fig. 1, between which the crossed coils move are concentric with the core 13 and the axis of movement but are asymmetric with respect to one another in so far as their effective polar faces extend over different arcs, for example the pole piece 11 may have its pole face 11<1> extending over an arc of 66 degrees whilst the pole piece 12 has its pole face 12<1> extending over an arc of 56 degrees. The angle between the current and pressure coils is of the order of 80 degrees. The potential coil is wound on a wide and thick former so as to improve the damping in the end position where it is in a strong field. The push-button 20, Fig. 4, for closing the supply circuits has an arm 23 which normally lies in a radial depression in the casing 21 for normal operation. The push-button 20 is free to be rotated and is provided with a pin 25 which, when the push-button 20 and arm 23 are rotated to the position shown, rides under a cam 26 to hold the push-button down. The arm 23 then projects over the edge of the casing and prevents the instrument from being closed or packed away with the supply circuits closed. For assembly a slot 27 is cut in the casing for the passage of the pin 25, the pushbutton then being turned through 180 degrees and the arm 23 screwed in. The push-button may be replaced by a lever having a camshaped hub which closes the circuits in one position of the lever, which is so arranged that the instrument lid cannot be closed when the lever is in this position. Specifications 350,715, 523,978 and 523,979 are referred to.
