Abstract: 407,366. Table games. DRIVER, P., 13, High Cliff, Cleethorpes, Lincolnshire. Sept. 8, 1932, No. 25084. [Class 132 (ii).] Game apparatus comprises a table or like level or slightly inclined surface embodying in combination a plurality of plates or trap doors pivoted so as to be free to rotate during play, and means for directing a disc, coin, counter or like article on to, and towards any desired part of, said surface. The apparatus comprises a framework in which a plurality of square, oblong, circular, hexagonal or diamond shape plates a forming substantially the whole of the playing surface are pivotally mounted. In the construction shown, the square plates a have inverted V-shaped lugs w situated in slots in an angle iron member s and are pivotally mounted on an axis b which is displaced from the centre line of the plates. The smaller of the portions of the plates into which they are divided by the pivotal axis b are loaded underneath by weights c so as to engage adjustable screw stops or supports v. When a coin, disc, counter &c. is rolled or projected on to one of the plates, it tilts up and the coin &c. drops into a shoot d and slides to an opening e where it is delivered to the player. The coin &c. can be rolled on to the plates a in any direction by means of a plate g having an inclined groove or slot f and attached to a pivoted standard i on a base plate k. In a modified construction the coin &c. may be rested flat upon a small pivotally movable board inclined to or coplanar with the playing surface and provided with a groove or like guide and a trigger-operated spring whereby the coin &c. may be projected edgewise towards any plate. The playing surface is preferably covered by glass l mounted in a lid m hinged over the table. The plate g in this case extends through a slot in one side of this lid. The apparatus is preferably contained in a casing n to which the lid m is hinged and provided with a door or doors o, p. A coin receptacle may be formed in the casing below the coin returning shoot d to receive over-shot coins through gaps r. All the doors to the interior of the casing and also the lid may be provided with locks. In modifications, the table may be slightly inclined to avoid the coins &c. rolling off, the framework may be of any desired shape and divided into areas of circular, oblong, hexagonal, diamond or any other shape to receive trap-doors of like shapes, and it may be made of metal, wood or a condensation product such as that known under the Registered Trade Mark "Bakelite."

Abstract: 1,107,416. Radar. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 14 June, 1965 [17 June, 1964], No. 25125/65. Heading H4D. In a monopulse radar with two channels, each having a primary element which cooperates with a common reflector so that two narrow beam radiation polar diagrams are produced (Fig. 1, not shown), in which the signals A and B received in the channels are made available as outputs representing respectively the sum and the difference of the said signals, circuitry is provided to derive from those outputs a further output representing the product of the said signals. As described, the outputs (A+B) and (A - B) are taken through I.F. amplifiers 1, 2, Fig. 3, to an adder 3 and to a subtractor 4, the outputs of which, representing, respectively, 2A and 2B are taken to a phase-multiplying detector 5, from which a product representing A.B is taken to a final stage 6. In an alternative, the sum and difference outputs are taken through amplifiers (10), (11), Fig. 4 (not shown), to square-law detectors (21), (22), whose outputs are taken to a subtracter (23), from which a product output is obtained. It is stated that when echoes of pulses are received from a plurality of moving targets, unwanted product values of signals from different targets may be eliminated by providing integrating devices in the final stage 6, Fig. 3, to take advantage of phase differences between signals (which may be due to the Doppler effect). Such a device may make use of a suitable fluorescent display screen of a cathode-ray tube.

The arrangement is such that there are pauses while a crank returns through approximately 180‹ before the drive again becomes operative so that the ram pauses before each feed stroke and at the conclusion of the stroke is able to yield to back pressure and the drum 28 pauses with its cylinder 29 in alignment with the cylinder 10 prior to its rotary movement and also pauses in the position where dough is discharged. The rods 16, 35 may be adjusted in length by packing pieces at the ends or by screw-threaded components. The eccentrics 15, 33 are attached midway along the levers 13, 32 and the lever 32 is attached to the drum 28 by a link 31. The eccentrics 15, 33 are urged down over a horizontal dead centre position and are returned through 180‹ by weights or springs such as 20. The mould cylinder 29 is provided with a plunger 36 carrying a roller 37 adapted to engage an adjustable inclined plate 38<a> whereby, as the cylinder is being swung out of alignment with the chamber 10 to cut off the dough by a knife 30, the plunger 36 is moved to force some of the dough back into the chamber 10 and leave the required amount in the cylinder. The plate 38a is adjustably mounted as by a screw 40, hand wheel 39 and locking wheel 43 in a block 38, so that the amount of dough left in the cylinder is adjustable. The dough is finally discharged by a lever 45 as described in Specification 443,628. To expose the plunger 36 for removal, the plate 38<a> and block 38 can be swung up about a pivot 42 after removal of a securing pin 41. The hopper is provided with rollers 22, 23 mounted to produce a tapering feed and driven by chain and sprocket gearing 25, 26 from the main shaft. The sprocket teeth may be intermittent to stop the feed during the charging stroke of the ram. The bearings are spaced away from the rollers to prevent interchange of oil and dough.

Filed: 1947-09-20
Abstract: 637,329. Aerials. CARY.R.H.J. Sept. 20, 1947, No. 25651. [Class 40 (vii)] The cavity behind an air-intake aperture of an aircraft has a coupling device for injecting or extracting electromagnetic energy so that the aperture may function as a slot aerial. Fig. 4 shows a section through an airplane wing containing an air intake to a jet engine. The aperture communicates with an electrically conductive cavity 3 formed of a four-sided passage closed by a metallic grid or mesh 4 normally provided to exclude extraneous matter from the engine. In the absence of a grid the outlet air duct terminates the cavity. Coupling with the cavity in a manner which avoids impeding the airflow is effected by an auxiliary cavity 6 disposed in the lower leading edge of the wing and joined to the main cavity by a slot 7 in the common wall. A pick-up probe 8 or loop projects into cavity 6. When the construction is of a non-conductive material it is necessary to provide the cavity, and the wing surface in the neighbourhood of the aperture, with a conductive coating. Preferably, slot 7 is sealed with a dielectric material. In an alternative embodiment, Fig. 3 (not shown), a pick-up probe or loop projects directly into the air-intake cavity. Two air inlets may be coupled to function as an array or, if they are symmetrically placed about the aircraft, Fig. 1 (not shown), may provide overlapping polar diagrams for a direction finding or bearing system. With the dimensions of apertures and cavities normally encountered, satisfactory wide-band operation is possible.
