Title: Improvements in or relating to aerial systems
IPC: H01Q13/06
Filed: 1956-09-03
Abstract: 796,915. Aerials; radio direction finding. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 3, 1956 [Sept. 21, 1955], No. 26862/56. Class 40 (7). An aerial system for a gun-control &c. followup radar system and which provides a single axial primary lobe when transmitting and, symmetrically around the latter, four separate directional primary lobes intersecting one another when receiving, comprises four adjacent horns or waveguides 1, 2, 3, 4, provided respectively with resonant apertures 5, 6, 7, 8, the phase centres of which are closer together than the geometrical centres of the guides and the whole assembly is terminated by four convergent metal plates 11, 12, 13, 14, forming a truncated pyramidal hood, the smaller open end of which is supported at the focus of a paraboloid mirror 15, preferably as shown in Fig. 5, by employing the waveguides themselves as supporting means. The effect of the hood on the impedance matching of the apertures is corrected by means of diaphragms (not shown) in the guides and parasitic couplings between the guides are eliminated by means of quarter-wave trap filters one of which is shown at 9 (Fig. 6). With this arrangement the level at which the receiving lobes intersect is about 3 db. below the level corresponding to the maximum. In operation it is required that during transmission the four waveguides be energized simultaneously in phase and, during reception, that the four waveguides feed the receiving equipment independently. This is achieved by the arrangement shown in Fig. 7 in which the transmitter (magnetron &c.) 9 feeds, via a unidirectional coupler K, a network comprising four " magic T " hybrids T5, T6, T7, T8, the first three of which, during transmission, each operate to divide its input signal into two equal parts so that each of the waveguide elements 1, 2, 3, 4 receives a quarter of the energy, this being caused to be in the same phase at each element by arranging the overall electrical lengths of the supply guides between the transmitter and the elements to be equal to each other. During reception the energy received by each element 1, 2, 3, 4 and denoted in Fig. 7, by 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP>, respectively, is combined as indicated, by means of the " magic T's " (T5, T6, T7, T8) and supplied, via coupler K and lead 16 to a normal radar receiver, via T-R cell R13 to a receiver from which the elevation error is derived and, via T-R cell R14 to a further receiver from which the azimuth error is derived. The difference signal (1<SP>1</SP>+4<SP>1</SP>) - (2<SP>1</SP>+3<SP>1</SP>) derived from cell T8 is not used and is absorbed in a matching load 17.

Abstract: 628,445. Mixing-machines. LAMBERT, F. G. Oct. 7, 1947, No. 26945. [Class 86] ' The stirrers of a mixer are mounted on a cross-shaped member 3 which fits on the top of a stationary container 1 and is prevented from rotation by the handles 2 of the container. There are three stirrers; one 8 is stationary and rigidly secured to the member 3, one 9 which is freely rotatable on a shaft 6 passing vertically through the member 3 and a third 12 which is fixed to the shaft 6 and rotates with it as a handle 7 is turned.

Title: Improvements in thread cutting mechanisms
Inventor: VINES RALF
IPC: B65H54/71
Filed: 1951-11-23
Abstract: 706,584. Measuring and cutting thread &c. WALKER & SON, Ltd., T. Nov. 24, 1952 [Nov. 23, 1951], No. 27555/51. Class 120(3) [Also in Group VIII] Mechanism for cutting predetermined lengths from thread &c. 1 led past a cutting blade 42 includes a cam member 4 having a pair of oppositely directed surfaces 7, 8 of predetermined length and controlled by the thread to move in relation to a camfollower 15 at a speed proportional to that of the thread. The cam-follower bears against cne surface 7 or 8 until it reaches the end when it is automatically transferred to the beginning of the other surface against which it bears until the end is reached when it is transferred back to the beginning of the first surface, the resultant movements of the cam follower from one surface to the other being used to operate blade 42 to sever the thread. The thread, as described, is being wound on to a winding bobbin from a storage bobbin and on its way passes around a driving drum which transmits drive through a variable speed gearbox to a second cam member 3 and thence through a reduction gearing (e.g. of 100:1), to cam member 4. Member 4 has diametrically opposed radial slots 9, 10 leading from outer cam surface 7 to inner cam surface 8; member 3 has inner and outer surfaces similar to surfaces 7, 8 connected by inclined slots 27, 28. Follower 15 is carried on a bell crank 17 and is biased by a spring 20 to a position, mid-way between surfaces 7, 8. Follower 15 moves along surface 7 until it is opposite slot 9; when slot 28 of the faster moving member 3 moves into register with the follower, the latter is moved by spring 20 into engagement with slot 28, continued movement of which forces the follower down slot 9 and transfers it to cam surface 8. The follower now moves along surface 8 until it is opposite slot 10 when it is transferred by means of slot 27 back to surface 7. The movements of the follower from one cam surface to the other cause alternate rocking movements of bell crank 17 which act through a lost-motion connection 30, 31, to snap a lever 32 over against one or other of two stops 37, 38. Movement of lever 32 operates through another lost-motion. connection 39, 40 to swing blade 42 about a pivot 41 so as to sever the thread 1; blade 42 is two-edged so, that it will cut on both upward and downward movements. When. thread 1 is severed, the drive to the driving drum is interrupted and the cam members are stationary until the thread is rethreaded and winding continues. By altering the ratio of the gearbox driving cam 4, the amount of thread passing driving half a revolution is varied and a different length of thread is cut off.
