Patent GB-1185781-A (GB)
Title: Clutter Fortified Moving-Target Tracking System
Inventor: VEHRS CHARLES LEONARD
IPC: G01S13/534
Filed: 1968-02-08
Abstract: 1,185,781. Pulse radar. NORTH AMERICAN ROCKWELL CORP. 8 Feb., 1968, No. 6335/68. Heading H4D. In angle-tracking of moving targets in ground clutter by a non-coherent monopulse radar, the target signal becomes the Doppler reference if it exceeds the clutter and tracking of the clutter or a direction intermediate the clutter and target may ensue. It is known to enhance the clutter to reduce this (U.S.A. Specification 3,365,715) but tracking errors due to asymmetry of the enhanced clutter arise. According to the present invention such tracking errors are reduced by injecting a sample of the signal in either channel E A , E B  into the other. Like delays 26, 27 correspond to half the gate interval of a range tracker or, if the latter is not provided, to three times the width of the transmitted pulse. To improve further the symmetry of the clutterreference signals, " sample-and-hold " means 32, 33 are each connected to the normalized sum channel E s  and have a gate input from the range. tracking circuit 35; the gate input to means 33 being delayed by an interval equal to that of delays 26, 27. Differential means 36 provides a gain control bias which is injected via a gate 39 into the A.G.C. input line 37; gate 39 is operative from the input and output of delay 34. Further clutter enhancement may be added by incorporating a delay 40 to provide a sum channel clutter sample from a range interval removed from the target range; the injection of that sample into the E A , Eg channels may be controlled by a gate 43 actuated when the output of a summer 42 is less than a threshold level.
Patent GB-637866-A (GB)
Title: Improvements in or relating to apparatus for utilisation of intra-nuclear atomic energy
IPC: H05H1/12
Filed: 1947-03-06
Abstract: 637,866. Utilizing atomic energy. JAPOLSKY, N. S. March 6, 1947, No. 6338. [Class 39 (i)] Streams of atomic nuclei are produced in containers 1, 2 by means of rotating magnetic fields established by currents in high-frequency polyphase windings 10, 11. These streams of nuclei pass through tubes 3 and intersect at right angles in a cylinder 4, effecting disintegration of some of the particles. One stream has a velocity producing a de Broglie wave packet (a resultant wave system produced by the motion of protons or magneto-protons). This packet interacts with the particles of the other stream to separate negatively-charged and positively-charged particles. By reason of their mass, the latter collect on a cylinder 5, while the negatively-charged particles collect on positively-charged radially-disposed strips 7. An alternating magnetic or electric field diverts the particles to vary the rate of collection at 5, 7 and thus produce a pulsating voltage at 6, 9.

Mounting spare wheels on vehicles.-In sparewheel holders for motor-vehicles of the kind comprising a hinged bracket C with a dummy hub X<2> or the like on each side for holding a pair of spare wheels X, Y against the back of the vehicle, the bracket is retained in raised position by a single central tie-member, such as the link E, which is mounted upon a chassis member F, extends to the dummy hub or the like nearer to the back of the car, and is adapted to be disconnected therefrom when the bracket is to be lowered. As shown, the link may comprise two parts screwed together. The Provisional Specification also refers to the mounting of the holder on a vertical axis at the side of the vehicle and to the construction of the bracket as a plate instead of a framework.

Abstract: 325,125. Seferiadis, B., and S.C. Patents, Ltd. Feb. 27, 1929. Pulp, adding special substances to; paper, treating with special materials.-The aroma of burning cigarette paper is improved by incorporating a natural or artificial resin-gum in the paper pulp, or by steeping the finished paper in a gum solution. In an example 3 to 5 per cent of a solution of mastic gum, prepared by macerating the gum for 24 hours with acetone and alcohol, is added to the pulp. In another example a 1-5 per cent solution of the gum is prepared by pulverizing and drying the gum, and then dissolving it in acetone. Calcium carbonate is added until a precipitate is obtained, this precipitate is mixed with the paper paste in the breaking vats.

Abstract: 622,061. Induction machines. NIELSEN, H. M. SCHACK-. March 7, 1947, No. 6532. Convention date, March 7, 1946. [Class 35] In order to prevent the development of unduly high voltages at the terminal between the auxiliary winding and the condenser of a capacitor motor, the winding is subdivided and the parts alternately connected in series with two or more condensers. As shown in its simplest form, the auxiliary winding is divided into three equal parts be, fh and ij, with the condensers ef, hi between them. Vector diagrams are given showing that the maximum potential of any point to earth is substantially reduced by this means. It is stated that further subdivision produces even better results. The Specification as open to inspection under Sect. 91 describes an auxiliary winding which is divided into two parts separated by a single condenser, and it is also stated that the condenser and winding may be divided into numbers of parts that are equal or differ by one. This subject-matter does not appear in the Specification as accepted.

[Also in Group XXXV] A switchgear component with a high-voltage conductor embedded in solid insulation has a metallic layer or the surface of the insulation connected to earth through a voltage indicator. As shown, a current transformer with primary winding 11, secondary winding 13, and core 14 all embedded in epoxy resin 12 has a metal layer 21 on the surface connected to earth through a neon lamp 23 and push-button switch 24. When the switch 24 is opened the layer 21 which may be a metal foil or metal sprayed on to the surface, acts as a capacitor electrode and assumes a voltage to earth sufficient to light the lamp 23 and indicate that the transformer is alive. Three such current transformers may be used on the line side of a three-phase circuit-breaker, and two lamps will still indicate even if the other has failed.

Abstract: 1294591 Polymeric carriers for proteins BOEHRINGER MANNHEIM GmbH 17 Feb 1970 [19 Feb 1969] 7538/70 Headings C3G C3H and C3P  Copolymers to which water-insoluble proteins can be bound are derived from (a) acrylamide, (b) ethylene-maleic acid (or anhydride) copolymer and/or (c) maleic acid (or anhydride), and (d) N,N<SP>1</SP>-methylene-bisacrylamide and/or ethylene diacrylate in a weight ratio a : b : c : d of 3 : 0À5-1À5 : 0À05-4 : 0À075-0À9, the weight ratio of a : b+c being not more than 4. (Components (b) and (c) can be present simultaneously or alternatively and, thus, the above weight ratios cover the amounts of (b) and (c) which are to be used when they are present.) The copolymers can be prepared by polymerizing components (a) to (d) in the presence of free radical initiators, e.g. propionio acid nitrile or ammonium persulphate; when the ethylenemaleic acid (or anhydride) copolymer is present, graft polymerization is stated to occur. Polymerization is suitably effected in an aqueous medium which may include a phosphate buffer. The polymer obtained is desirably granulated by forcing through a sieve of the desired mesh size and then washed with water and lyophilized. For fixing of proteins, the dicarboxylic acid residues in the polymer must be in anhydride form; this can be achieved (if not already the case) by heating the lyophilized polymer at 80-120‹ C. in a vacuum or at 160- 220‹ C. at atmospheric pressure. Proteins which can be bound to the copolymer carriers include enzymes, enzyme inhibitors, antigens and anti-bodies. In examples trypsin and calf serum albumin are treated with the copolymers in aqueous medium at pH 5À2.
