Title: Navigation system
IPC: G01S3/42
Filed: 1949-10-12
Abstract: 668,431. Electric navigation system. BENDIX AVIATION CORPORATION. Oct. 12, 1949. [Jan. 5, 1949] No. 26239/49: Class 40 (i). A direction indicator comprises a directional gyro with no precessing. arrangement, controlling the pointer of a compass card, whose readings are monitored by the intermittent use of an earth inductor device alternatively with the gyro. As shown (Fig. 1) a gyro 10 has an energized rotor coil 18 attached to its vertical trunnion 14, so that movement of the craft to which the gyro is attached causes a voltage to appear in a rotor winding 23 via 3 phase stator windings 19, 22 associated with the gyro and a pointer 15 respectively, which is amplified at 30 to feed one winding 31 of a 2 phase motor 32 to rotate shaft 37, which, by energization of solenoid 43, is coupled to pointer 15 on a shaft 24 attached to rotor winding 23. Operation of relay 66 de-energizes gyro rotor winding 18 and energizes an earth inductor 17 whose 3 phase windings 49, 50, 51 are connected to the 3 phase stator winding 22 of the pointer shaft 24, so that if gyro 10 has suffered any precessional movement, an error voltage appears in winding 23, which is now used to drive stator winding 19 of the gyro through shaft 37. This cycle is repeated after time intervals determined by the action of two bimetallic strips 61, 73 connected so that initially the earth inductor 17 controls for a longer period than the gyro 10, but after the operation of strip 73, the time periods are reversed. In another embodiment (Fig. 2, not shown), the earth inductor 17 corrects the compass reading by driving stator winding 22 and also the compass dial 16. Specification 668,401 is referred to.

Title: Rubber and its preparation for manufacture
IPC: C08J3/03
Filed: 1934-09-14
Abstract: Artificial dispersions of rubber, guttapercha and the like, prepared with the aid for example of soaps, glue, casein, albumen, starch, sulphonated compounds, saponin, dextrin, caramel, gums, are given properties approaching those of natural latex by removing or rendering inoperative some of the stabilizers or dispersing agents used in their preparation.  Removal may be effected by dilution, preferably with a weak soap solution, e.g. a 1 per cent solution of potassium oleate, and centrifuging or by creaming preferably after dilution, as by adding sodium alginate, gum tragacanth, or Iceland moss.  Alternatively, the stabilizers may be rendered inoperative by the addition of formaldehyde, trioxymethylene, or other tanning agents.  Dispersions thus treated, yield tough and elastic coagula, can be more easily gelled with sensitizing agents, and so are more suitable for the formation of cellular rubber.ALSO:Artificial dispersions of rubber and the like are given properties approaching those of natural latex by removing or rendering inoperative some of the stabilizers or dispersing agents used in their preparation.

Title: Improvements in or relating to distance measuring devices
Inventor: WIMBERLY FLOYD TYRUS
IPC: G01S1/02
Filed: 1953-09-25
Abstract: 767,293. Radar. RAYTHEON MANUFACTURING CO. Sept. 25, 1953, No. 26516/53. Class 40(7) A frequency-modulation type radio altimeter is arranged to determine distances over a first portion of the range scale by measurement of the frequency difference between the echo and direct signals, the modulation sweep band width and frequency being maintained constant, whilst over a second portion of the range scale the frequency difference is maintained constant and adjustment of the sweep bandwidth is utilized for the measurement of range. Scale compresion which is substantially logarithmic is effected over the second portion of the range scale. In one embodiment a sweep generator unit 13 feeds modulation signals through an amplitude control device to modulator 12 modulating transmitter 11. Echo and direct signals are mixed in receiver 16 and fed through amplifier 17 and limiter 18 to circuit 20 which develops a negative direct current voltage proportional to the frequency of the limited signal. This voltage is derived across resistor 25 and is added to the voltage derived from low altitude control potentiometer 30 and applied to modulator 35. A 400 cycle input is applied to transformer 39 and the output from the centre-tapped secondary 40 fed through 90 degree phase shifting networks to the modulator valves 35 and 37. The side 37 of the modulator is supplied with a fixed grid reference voltage and the joint anode output is a 400 cycle signal of an amplitude dependent on the amount that the input signal to the grid of valve 35 differs from the reference level and a phase of 90 degrees or 270 degrees according to which is greater. This output is fed through power amplifier 52. to one winding 53 of motor 50. The other winding 51 of the motor is fed from secondary 41 of transformer 40. Motor 50 operates to adjust potentiometer 30 to a position at which the error voltage ceases to exist up to an altitude of 200 feet. Above this the slider of the potentiometer is driven on -but introduces no increase in resistance. Motor 50 also drives devices 58 and 59 moving indicator 61 (see also Fig. 6) in accordance with its rotation and therefore range. Above 200 feet the amplitude control device between units 13 and 12 becomes effective and includes two linear law variable potentiometers 71 and 72 having a portion of the windings corresponding to the 0-200 ft. range non-resistive. These potentiometers and the associated circuit are controlled by motor 50 and vary the modulation sweep width to hold the output of circuit 20 equal to the output of potentiometer 30 which is constant over this part of the scale. The position of the motor shaft is, therefore, still a function of range and the layout of the circuits including potentiometers 71 and 72 is such that the range scale is approximately logarithmic form 200 to 20,000 feet. Reference has been directed by the Comptroller to Specification 661,769.
