IPC: H01Q19/13
Filed: 1950-06-08
Abstract: 675,245. Aerials. STANDARD TELEPHONES & CABLES, Ltd. June 8, 1950, No. 14323/50. Class 40 (vii). In a directional aerial system comprising a paraboloidal reflector 1 fed at the focus by a waveguide horn 2, mismatch due to energy reflected back to the horn is minimized by displacing a circular apex portion 4, 5 of the reflector along the axis of the system to a position 6, 7 so that the energy reflected back to the form from the displaced apex portion substantially cancels that reflected back from the other portions of the reflector over a relatively wide frequency band. The Specification shows that optimum cancellation is effected when b=#f#/3 and d=(n+1/12)# where b is the radius of the displaced portion, d is the displacement, f is the focal length of the paraloloid, A is the operating wavelength and n is an integer. In order to avoid distortion of the main radiation pattern, d should be as small as possible, i.e. n=o. As shown, the apex portion is displaced towards the focus but the displacement may be in the reverse direction. The displacement may be effected by mounting on the apex a circular plate of thickness d formed to the same curvature as the apex or by spacing a similarly shaped thin plate by brackets, or adjustable supports. Specification 581,457 is referred to.

Title: Improvements in or relating to coating compositions
IPC: C09D101/18
Filed: 1947-05-30
Abstract: Hydrous iron oxide for use in coating compositions giving a so-called " transparent " finish (see Group IV (a)) is prepared by heating 295 g. of hydrated ferric chloride and 100 g. of sodium sulphate in 10 litres of water to 70 DEG  F. and adding slowly with stirring over a 15-minute period 5 litres of water containing 240 g. of sodium carbonate to a final pH of 7.2.  The precipitate is washed till substantially sulphate free.  In a further example, an oxide containing iron in both the ferrous and ferric states in the proportion corresponding to Fe2O3.2FeO is prepared by adding slowly to 220 g. of sodium hydroxide dissolved in 4 litres of water at 70 DEG  F. a solution of 278 g. of ferrous sulphate crystals and 270 g. of hydrated ferric chloride.  The precipitate is stirred for 25 minutes, filtered and washed sulphate free. Specification 499,790, [Group IV], is referred to.ALSO:A coating composition giving a so-called "transparent" finish comprises an organic film-forming vehicle containing a cellulose ester or ether and, as a pigment, hydrous iron oxide of average particle diameter less than 100 millimicrons.  The pigment is transferred to the vehicle from the pulp state preferably by means of a flushing process, it being of importance not to dry and grind the oxide.  The cellulose derivative may be the nitrate, acetate, an acetate mixed ester or an ether such as ethyl cellulose.  The oxide is incorporated in amounts of 2-10 per cent by weight of the total composition, depending on the desired colour and transparency.  A small proportion of aluminium powder may be added if desired.  Other hydrous metal oxides such as those of manganese, aluminium, cobalt, chromium and copper may be co-precipitated with the iron oxide, giving variations in colour. In an example (all parts per cent weight of total composition), 12.3 parts of water wet cellulose nitrate and 4.0 parts of hydrous iron oxide (70.7 per cent water) (see Group III) are charged into a kneader, mixed for 5 minutes, and then 3.3 parts blown castor oil added and the kneading continued for 30 mins. 3 parts dibutyl phthalate are added and the water which separates is decanted off. A further 3.0 parts of hydrous iron oxide pulp and 1.8 parts of dibutyl phthalate are added, the separated water being again decanted. Residual water is removed by vacuum.  This intermediate is combined with 3.7 parts cellulose nitrate, 20.1 parts denatured ethyl alcohol, 33.5 parts ethyl acetate, 6.2 parts butyl alcohol and 9.1 parts of a resin composition comprising 30 per cent toluene and 70 per cent of a glyceryl phthalate/coconut oil/dibutyl phthalate resin of composition 60/15/25. Specification 499,790 is referred to.
Patent GB-163709-A (GB)
Title: Improvement in electromagnetic wave signalling apparatus
IPC: G01S1/02
Filed: 1921-05-24
Abstract: 163,709. Mauborgne, J. O., and Hill, G. May 24, 1920, [Convention date]. Aerials; bearings, determining; duplex signalling; heterodyne receiving systems; coupling aerial and detector circuits. - The receiving-aerial consists of a long helix of fine insulated wire, preferably wound on a core of insulating material. The aerial is not earthed, is not connected to any open aerial system, and has no associated tuning arrangements, the inductance, capacity, resistance, and induced electromotive force being distributed throughout its length. Energy received on such an aerial gives rise to a definite potentialcurrent wave distribution on the coil, the exact form depending on the length of the aerial, its inclination to the wave front, and the frequency of the received energy. The detector or amplifier is connected to the aerial by means of a slider which is adjusted to a point on the coil which is the antinode of the potential distribution corresponding to the particular signal to be received. As shown in Fig. 2, the slider B makes an electrostatic coupling between the coil-aerial A and the grid terminal of an amplifying set C, the filament lead being disconnected and serving simply to counterbalance the grid lead. Instead of an electrostatic coupling B, a sliding coil may be employed to provide an electromagnetic coupling with the aerial at a current antinode; or a slider making direct metallic contact may be used. As shown in Fig. 4, the filament lead is connected electrostatically to the aerial by means of a sliding metal disc D of comparatively large area. In Fig. 9, a local source of oscillations H is directly connected to the amplifier for heterodyne reception; or the source H may be thereby coupled inductively to the receiver. The currentvoltage-distribution in the coil-aerial varies with the inclination of the aerial to the wave-front of the incoming energy, thus giving rise to a corresponding shift in the point of the potential antinode which is measured by means of the slider B. This feature is utilized as a means of direction-finding, which is applicable whether the source is on a ground station or on an aircraft. For this purpose, the aerial with slider B is supported on a swinging frame F, Fig. 5, carried on a rotating base K, so as to be movable in altitude or in azimuth, pointers R, V, giving the required measurements. To ensure the selectivity, two coils may be mounted at other angles to each other. By using two or more sliders B combined with one or more coil aerials, duplex or multiplex reception may be secured. All leads and associated apparatus should be screened from incoming energy, and from any interaction effects arising from the coil-aerial.

Title: Fishing reels
IPC: A01K89/016
Filed: 1971-05-12
Abstract: 1307345 Fishing reels BOJS MORNER 12 May 1971 [26 May 1970] 14460/71 Heading A1A The time spool 20 of a fishing reel is driven through an adjustable slipping clutch from an intermediate shaft 4 connected through double gear wheel 32, 33 to drive shaft 28 rotated by crank 15 so that when the crank is turned in the direction opposite to winding- up the clutch is progressively disengaged while braking is progressively applied to oppose rotation of the crank. The intermediate shaft 4 is journalled on drive shaft 28 which is journalled on shaft 30 attached to the frame 1. Between shafts 4 and 28 is an assembly, see Fig. 3, comprising ring 37 fixed to shaft 28 and carrying pins 38 against which cams 39 and balls 40 abut, and a ring 8 journalled on shaft 28 and carrying springs 42 which engage slots 43 on shaft 4 so that the ring rotates with this shaft. Springs 42 abut a nut 9 rotatable on the end of shaft 28 to adjust the compression of the springs which urge movable thrust plate 7 via flange 45 on ring 8 towards thrust plate 24 thereby pressing the thrust plates, both of which rotate with shaft 4, against friction surfaces 6, 23 on the sides of the line spool. Springs 42 also press ring 8 against ring 37 via balls 40 and thus urge shaft 4 to the right with respect to shaft 28 which generates frictional forces between these shafts at the bearing surfaces of bush 10 and, since the shafts rotate at different speeds, produces a braking action on the shafts. Nut 9 may be screwed hard against thrust plate 7 to effect a rigid connection to the spool. The line spool may be braked by deflecting crank 15 to press friction pad 17 against surface 18 of the line spool. In use when the crank is held stationary or rotated to wind in the line the torque at which the clutch will slip is that set by nut 9. If however the crank is not held and the line is drawn out the spool will tend to rotate the shafts 4, 28 in the direction opposite to winding up whereupon the relative motion of rings 37, 8 will cause balls 40 to ride up cams 39 pushing ring 8 to the right thereby reducing the pressure on the thrust plates and increasing the slipping of the clutch. The relative motion of the shafts 4, 28 will be increasingly resisted by frictional braking between them at bush 10 until they are finally stopped when the pull from the spool is balanced. Further movement of the handle by hand in the direction opposite to winding up will release the clutch completely and this movement will be resisted by increased braking forces, the maximum being reached when ring 8 abuts bush 10.

Abstract: 1,190,474. Transmission systems; input-output control. BURROUGHS CORP. 27 March, 1968 [27 March, 1967], No. 14699/68. Heading G4A. In a digital data transmission system in which a plurality of terminal units communicate with a central memory by way of data communication lines, line control units, input-output channels and a central control unit for allocating memory accesses to said channels, means are provided for switching the line control units from a write state to a read state in response to detection of a predetermined control code character in the transmitted data. The invention is described as applied to the time-sharing computer system of Specifications 1,176,894 and 1,172,494. In response to a "flip" command being received by a line control unit, an interrogation signal is transmitted to the relevant terminal unit. Detection by the control code matrix of an "end of message" control character switches the line control unit from its write state to its read state so that an acknowledgment signal indicating whether or not the terminal unit has information to be transmitted may be accepted and acted upon by the control unit. A similar poll command is described whereby a string of terminal units on a single data communication line may be interrogated in turn with the line control unit changing from its write to its read states repeatedly until a terminal unit having data to be transmitted is found, i.e. a positive acknowledgment signal is detected by the control code matrix.
