Title: Improvements in or relating to Reservoirs
Inventor: COLQUHOUN ROBERT SUTHERLAND
IPC: E03B11/00
Filed: 1967-06-08
Abstract: 1,191,684. Reservoirs. R. S. COLQUHOUN. 5 June, 1968 [8 June, 1967], No. 26504/67. Heading E1X. To prevent evaporation or contamination of water in a reservoir there is arranged over the reservoir 12 an aitight and gastight cover 18 that is sealingly secured at a level above the maximum intended level up to which water is to be stored in the reservoir to a rigid support 15 surrounding the reservoir. The cover may be supported as a dome by pressurised air beneath the cover, the air being blown in beneath the cover as required by a fan, the motor of which is controlled by a switch operable in accordance with the tension in a wire or rope extending from the switch over the cover to an anchorage at the outside of the reservoir. In a second constructional form the cover floats on the water and is centrally weighted so as to cause any rainwater to collect in a sump formed by the weights at the centre of the cover. The rainwater is removed from the sump by pumping. Also a float may be positioned in the sump of the cover, which may be wholly or partly constructed of butyl rubber or nylon mesh reinforced butyl rubber, the cover being formed of two or more welded together, strips of such material. Syphons are formed in the air and water inlets and outlets to prevent leakage of air through said inlets and outlets.

Filed: 1946-09-05
Abstract: 630,137. Reversing-gearing; clutches. LANGDON, A. G. Sept. 5, 1946, No. 26713. [Class 80 (ii)] A bevel reversing-gearing, or its equivalent, is housed within a casing which is axially slidable to engage pre-set clutch plates for forward drive and to alternatively disconnect the drive ; reverse drive being obtained by braking the casing. A driving shaft 3 carries a bevel gear 4, the boss 4a of which is splined for engagement with a set of clutch plates 8 which are co-actable with clutch plates 9 splined to the casing 11, the pressure between the plates being preset by the screws 12. The casing 11 has inwardly projecting bosses 17 which engage the ends of a spider 15 carrying the intermediate bevel gears 5, and carried at its centre by extensions 3a, 7a of the driving and driven shafts 3, 7 respectively. The driving and driven bevels 4, 6 are located axially together with the shafts 3, 7 by sleeves 19, 23 clamped between the hubs of the bevels and the supporting bearings 20, 24. The hub of the bevel 6 carries the end plate 26 of the casing 11, which endplate has slidable pins 27 moved by cams 28 against an expanding washer 29 to move the casing axially to engage or disengage the clutch 8, 9. The cams 28 are turned by a sleeve 31 sliding on the sleeve 23 and actuated by a lever 35 through a fork 33. The lever 35 also carries a peg 45 which engages with a rocking lever 44 to depress a pin 42 and apply a band brake 36, against the force of a spring 41, to the sleeve 11 for reverse drive. , In a modification the clutch plates are positioned in the opposite end of the casing 11.

Title: Non-rotating antenna
IPC: H01Q3/26
Filed: 1972-06-08
Abstract: 1383126 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 8 June 1972 [11 June 1971] 26766/72 Heading H4A [Also in Division H1] A ro ating cardioid type radiation pattern is produced by feeding the elements of a suitable aerial array, such as a circular array, with modulated signals from respective outputs 6, Fig. 5, of a cylindrical coaxial distribution cavity 3. A transmitter supplies carrier frequency power to a power divider 8, one output of which is connected through a phase compensator 9, which may consist of coaxial cable providing a time delay equivalent to a whole number of wavelengths, to the centre conductor 5 of the cavity 3 at the input end thereof. The other output of the power divider 8 is connected through a phase adjuster 10, having a range of 360 degrees, to the input of a switching device 12. The cavity is provided with a plurality of radial probes 11, which may be either capacitive or inductive, and which are connected to respective outputs of the switching device 12. In operation, the probes are connected sequentially to the power divider 8 by the switching device 12, either one-by-one, or diametrical pair-bydiametrical pair (when the probes of each pair are fed in opposed phases). This induces the H 11  mode in the cavity, and the outputs 6 are fed from an R.F. impedance matching transformer located in said cavity. As described with reference to a TACAN beacon, the distribution cavity provides modulation at 15 Hz, and a superimposed 135 Hz modulation is obtained by sequentially turning off the elements of the array.

Abstract: 534,944. Printing-machines. STEVENS, A. H. (Miller Printing Machinery Co.). Oct. 2, 1939, No. 27047. [Class 100 (ii)] A printing-press is constructed with a type bed formed of a relatively light material, and one or more elements disposed on said bed of wearresisting material having a coefficient of thermal expansion different from that of the light material, the said element being secured to the bed so as to permit of relative movement thereto to compensate for differential expansion. As applied to a two-colour cylinder press the type bed is made of a light material such as aluminium, or of a plastic composition, and the pressure-receiving parts are made of steel, or other hard material so arranged in position that unequal expansion of the materials due to change of temperature does not cause warping. To the aluminium body 10 are secured steel &c. bearers 12, Fig. 3, which may be held in position by screws 14 screwing into the body 10 and passing through holes in the bearers of larger diameter than the screws. The steel plates 20 which receive the formes are held in position by means of recesses formed on the insides of the bearers 12, by similar recesses in a clamping- bar 21, Figs. 3 and 6, which is held in position by screws 22 passing through enlarged holes, and by recesses in plates 16 which receive the inking slabs and are held in position by screws 17 and keys 18 engaged by keyways of longer length.
