Title: System for evaluating trains of pulse signals
IPC: G01S7/292
Filed: 1965-04-09
Abstract: 1,102,299. Pulse radar. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 9 April, 1965 [10 April, 1964], No. 15241/65. Heading H4D. In a system for evaluating signals forming part of a composite train of signals divided uniformly into elementary signals of uniform width, the composite signal is examined at each of several contiguous amplitude levels which are uniformly spaced, the signal components in each amplitude level are extracted in respective selecting circuits arranged to transfer to an output circuit only signals at that level having predetermined width or widths in terms of elementary signal width, and the respective output signals at all amplitude levels are combined. The invention is applied to the detection of moving targets in the presence of clutter in pulse radar. Fig. la shows a typical amplitude-quantized radar return in part of a pulse repetition period, each vertical column corresponding to the duration of the transmitted pulse. Signal elements assumed to be from moving targets are shown by hatching; if the signal of Fig. la is examined at each of amplitude levels 1 to 8 the outputs are given in Fig. la. If signals having at most n contiguous elements are selected at each amplitude level and then added the result with n = 2 is shown in Fig. 1c. If the selection is of the presence of two contiguous elements the result is illustrated by Fig. 1d. Amplitude quantization to reduce the radar echo train to the form of Fig. la is by known technique utilizing a potentiometer and diode matrix terminating in OR gates and associated with an AND gate. Fig. 2 shows signal selection at amplitude level 3 (see also Fig. 1b). The output of AND gate 1 is as Fig. 3A and after delays 5, 6, each being a delay of one elementary signal width, as Fig. 3B, 3C. Ignoring the connections in Fig. 2 which are marked with a cross, waveform, Fig. 3D, appears at the output of AND gate 2. A bi-stable circuit 7 triggers into condition " 1 " when -waveform, Fig. 3D, switches from " 0 " to " 1 " and triggers into condition " 0 " when waveform, Fig. 3C, switches from " 1 " to " 0 "; waveform, Fig. 3#F, is obtained and applied with waveform Fig. 3C, to a further AND gate 3 to provide the wanted signal output Fig. 3H (see also level 3 of Fig. 1b). If only signals embracing two elements are required at the output, alternative AND gate 4 and bi-stable circuit 8 are used, the connection indicated by circles being omitted. Further arrangements for AND gate 3 are described, Fig. 4 (not shown), corresponding to other criteria relating to n.

Title: Improvements in or relating to the production of aviation gasoline by the catalytic conversion of hydrocarbon oils
IPC: C10G11/18
Filed: 1941-12-08
Abstract: 558.772. Cracking and hydrogenating oils. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. Dec. 8, 1941, No. 15829. Convention date, Jan. 29. [Class 32] [Also in Group IV] Aviation gasoline of high octane number and low acid heat is obtained by cracking a suspension of gas oil and catalyst at 750-900‹F., cooling the cracked products without fractionation or removal of catalyst to corresponding temperatures of 500-700‹F. and passing them to a further reaction zone into which hydrogen is injected to hydrogenate, polymerize and alkylate the unsaturated constituents of the gasoline. Extraneous hydrogen may be used, or hydrogen formed in cracking the gas oil. A Mirando oil fraction of boiling range 375- 500‹F. is charged through line 1 to a coil 5 heated to 750-950‹F. and the vapours mixed with catalyst from hopper 14 in injector 12 are passed to reactor 20 where they remain for 5-100 seconds. The cracked products are cooled in a heat exchanger 24 to 500‹F. and then discharged into the catalytic hydrogenation reactor 28 which is supplied with hydrogen through line 29. The vapours are separated from catalyst in cyclone 30 and fractionated in tower 36 to recover overhead a gasoline fraction which is collected in receiver 42 while higher boiling fractions are recycled through line 50. The catalyst after regeneration in regenerator 33 is returned to the fresh catalyst hopper 14 Pressure in the reactor 28 may be increased by passing the vapours through a pump 27. Gases removed through line 45 may be purified and recycled to the hydrogenation stage.

Title: Apparatus for ensuring the permanent synchronization of two shafts
Inventor: NUTTALL THOMAS CAYTON
IPC: H02P5/74
Filed: 1963-04-24
Abstract: 1,011,156. Control of A.C. motors; electric synchronizing. RANK-BUSH MURPHY Ltd. April 23, 1964 [April 24, 1963], No. 16130/63. Headings H2J and H2L. A synchronizing system comprises controlling shaft 1 and controlled shaft 2, shaft 1 actuating rotating member 3 associated with transducers 4-9 for developing signal sequences equally displaced in phase. The pick-off device may be photo-electric, inductive or capacitive. The signal sequences are appled to device 10 which develops a three-phase voltage having a constant amplitude over a range of speeds including zero speed. A further polyphase voltage is applied to the motor which is proportional to the time-differential of the first voltage. The output from terminals 11-13 is applied to respective terminals 14-16 of synchronous motor 17 driving shaft 2. Each of the leads comprises a number of secondary windings on transformers 19-24, the primary windings of which are each connected to a pulse generator 25-30. The pulse generators are controlled by the output from one of the transducers 4-9 and develop voltage pulses of alternate, polarity at each half-revolution of disc 3. Input signals from the transducers 4-9 are applied to trigger circuits 37-42, each providing two outputs of opposite polarity. One output from each trigger is taken both directly and by way of one of the delay circuits 43-48 to one of transistor switches 49-54 associated with transformers 19-24. The primary winding of each transformer thus receives a voltage pulse whose polarity is determined by the direction of the controlling edge in the applied signal, and the duration by the delay introduced by the delay circuit. The outputs from trigger circuits 37-42 are also applied to switches 65-60 performing the function of unit 10. When a positive-going edge occurs in the output signal from circuit 42, for example, switch 55 disconnects terminal 11 from earth and connects it to terminal 61 through switch 56. The terminal 61 provides a direct voltage equal to half the amplitude of the three-phase voltage. After the shaft 1 has turned through 30 degrees, switch 56 is actuated by a pulse from circuit 37 so that terminal 11 is now connected to terminal 62 providing maximum amplitude. After a further 240 degrees of rotation of shaft 1, switch 56 is returned to re-connect terminals 11, 61. Thereafter; switch 55 is returned to earth. Switches 57, 58, co-operate to generate another phase of the supply, while the third phase is produced by switches 59, 60.

Title: A method of obtaining bubble-free shaped synthetic resin masses
IPC: C08F265/06
Filed: 1942-11-16
Abstract: Shaped masses made of synthetic resin containing the group CH2=C<, e.g. methacrylic resins, are subjected to heat and pressure whilst they are immersed in an aqueous solution of a water-soluble substance inert to the resin being treated.  The strength of the solution is at least 1.5 molar.  The results of this treatment are as follows: (a) when the synthetic resin mass contains an appreciable amount of monomer, which has been added to facilitate the shaping of the mass, the heat treatment effects polymerization of the monomer without the support of a mould, and the pressure prevents formation of bubbles within the mass.  The higher the temperature, the greater is the tendency to form bubbles and the greater must be the pressure to prevent bubble formation; (b) when the mass contains no appreciable amount of monomer the heat treatment softens the resin and the pressure collapses voids within the mass.  The water-soluble substance may be sodium chloride, acetate, sulphate, alum or thiosulphate, magnesium chloride or sulphate, calcium chloride, sugar or glycerine.  Extruded rods may be so treated, e.g. in an autoclave and then cooled while still under pressure.  Examples of mixtures of methacrylate polymers and methacrylate monomers with benzoyl peroxide, which may be so treated, are described.  U.S.A. Specifications 2,101,107, 2,120,006 and 2,238,446 are referred to.ALSO:Shaped masses made of synthetic resin containing the group CH2 = C<, e.g. methacrylic resins, are subjected to heat and pressure whilst they are immersed in an aqueous solution of a water-soluble substance inert to the resin being treated.
