Abstract: 882,134. Aerials and radar. DECCA RECORD CO. Ltd. Aug. 22, 1960 [Aug. 25. 1959], No. 29120/59. Class 40(7). A directional aerial system comprises a length of square or rectangular waveguide in each of two forces of which is a series of radiating slots, the two series differing in their phase and/or amplitude characteristics to produce beams in different directions. Such a system for use in an airborne Doppler navigational equipment may radiate or receive over each of two pairs of simultaneous beams alternately, one pair being a beam directed forward and to port together with another beam directed after and to starboard, the other pair being a beam directed forward and to starboard with a second beam directed after and to port, so that ground speed and drift may be determined. The system comprises a waveguide 10, Fig. 1, in two opposite faces of which is a multiplicity of radiating slots, those in one face being a phased array and those in the other an anti-phased array (i.e. if fed in phase adjacent slots of the array in 11 would radiate in phase whereas adjacent slots in 12 would radiate in anti-phase), so that two beams are produced, one inclined forward and the other backward to the axis of the guide. By alternately feeding the guide from opposite ends the alternate pairs of simultaneous beams are produced and a suitable feed system comprises a transmitter 20, Fig. 3, and a receiver 21 coupled by a duplexer 22 and switches 24 to the guide 10 with matched loads 25 connected by the switches to the unfed end of the guide. The aerial system is mounted with the axis of the guide horizontal and the beams are directed downwards by parabolic cylindrical reflectors 18, Fig. 1, formed from the upper plate of a flared parallel plate transmission line 16. The aerial system may be carried on either a fully or pitch stabilized mounting and may be aligned with its axis parallelto the fore and aft direction of the aircraft or be rotatable to be aligned with the direction of travel. The aerial system may also be used for ground radar applications.

Title: Improvements in operating mechanisms for sliding doors
Inventor: PEARCE NORMAN GEORGE
IPC: A23F3/12
Filed: 1952-11-20
Abstract: 728,246. Door-operating appliances. MARSHALL'S TEA MACHINERY CO., Ltd. Nov. 19, 1953 [Nov. 20, 1952], No. 29312/52. Class 65(1). In order to allow of the operation of a sliding door in a moving support by actuating means on a stationary mounting, without movement of the door support causing movement of the door therein, the mechanism comprises a bellcrank, a first rod pivotally connected to the bell-crank pivot and to a point fixed relatively to the door support, a second rod arranged parallel to the first and pivotally connected to one arm of the bell crank and, directly or through a lever, to the door, and means for rotating the bell-crank to cause movement of the door relatively to its supports, and the bellcrank is capable of limited sliding movement in a plane parallel to the door. In the apparatus shown, a door 4 sliding in guides 5 on the container 1 of a tea-rolling machine, which has a circular motion on cranks 2, is actuated by a rod 17 which is moved in a straight line by a hydraulic or pneumatic piston or by a screw operated by hand or power, this actuating means being carried by the fixed base of the machine. The rod 17 is connected to one arm of a bell-crank 12 by a pin and slot 14, 15 which permits sliding of the crank transversely of the rod 17, and the crank is pivoted at 9 to a block which is slidable in a fixed guide 11 parallel to the slot 15 and is connected by a link 7 to a point 8 on the container 1, so that the crank is moved parallel to itself in the guides 11, 15 by the movement of the container. The second arm of the crank 12 is connected by a link 20, parallel and equal in length to the link 7, to a lever 22 pivoted at 8 on the container and connected at its other end to the door. Thus while the rod 17 is stationary the crank cannot rotate and the lever 22 is maintained in a constant position relative to the container 1, so that the door remains closed, and movement of the rod 17 causes rotation of the crank and consequent angular movement of the lever 22 about the pivot 8 to move the door on the container. In a modification, the pivot 8 is placed nearer to the door and the link 20 connected directly to the door (or a member rigid therewith). In a further modification, the rod 17 is arranged to move the guide 11 laterally instead of the slot 15, which is fixed.
