Title: Improvements in or relating to electrical musical instruments
IPC: G10H1/04
Filed: 1937-03-25
Abstract: 494,758. Electrical musical instruments. COMPTON ORGAN CO., Ltd., J., and BOURN, L. E. A. March 25, 1937, Nos. 8861/37; and 12350/38, (divided out of 494,759). [Class 88 (ii)] In electrical musical instruments in which a sound frequency voltage is generated in response to the operation of a note-key, automatically operating means for producing a pitch-wobble tremolo in the voltage are rendered operative in response to the operation of the note-key. Fig. 1 shows an electrostatic, and Fig. 2 an electromagnetic instrument. In Fig. 1, the usually stationary wave bearing disc 1 which co-operates electrostatically with a rotary scanning member (not shown) is spring- biassed at 14 and is rocked (a stop-switch 11 being previously closed) on depression of the note-key 2 which through contact 2b causes energization by battery 5 of an electromagnet 12a whose armature 12b is connected to the disc 1. The invention is particularly applicable in producing the Doppler effect of a swung bell, or the quiver effect in a large unswung bell, and means are also included for producing a gradual " die-away." In Fig. 1, the note-key 2 through a contact 2a and relay 6a causes polarization of the wave-rings representing its partials, by a source 3 through contacts 6c. The charging of the rings is through resistances 7 ; condensers 10 are arranged as shown, but are only such as will leave the attack nearly instantaneous. Condensers 9 do not affect the attack, being charged instantaneously. Both condensers, however, slow up the die-away, condensers 10 discharging through resistances 7, 8 and condensers 9 through the resistances 8. In Fig. 2, alternating sound currents are generated in coils 15 by adjacent rotary magnetic phonic wheels 17 when the cones 16 are polarized by coils 22 on closure of a note contact 18a energizing a relay 20a with contacts 20c. The pitchwobble tremolo is produced by rocking the cores 16 about the centres of the phonic wheels, closure of a second key-contact 18b (a contact 30 having been previously closed) energizing a magnet 27 to the armature of which arms 24 carrying the cores are connected, biassed by springs 26. Large-capacity condensers 23 (which may be connected to resistances, still however leaving the attack substantially instantaneous) produce a slow die-away by discharging through the coils 22. Means may be provided for adding an intensity tremolo. Specifications 388,036, 403,444, 433,050, 448,193, 453,846, 459,439, and 494,759 are referred to.

IPC: G01S13/86
Filed: 1964-03-03
Abstract: 1,105,601. Radio navigation. DECCA Ltd. 2 March, 1965 [3 March, 1964], No. 9003/64. Heading H4D. In an air traffic control system a radar compares its measurement of the position of an aircraft with the transmission from the aircraft of its position as obtained on the aircraft from a radio navigation system. The aircraft derives its plan position from a known hyperbolic phase comparison system and transmits such position together with its height by a known radio digital data link. In one embodiment data correlation is initiated by a ground control unit which (i) transmits a command signal to an aircraft, and (ii) provides a digital identity code signal into a first storage location in a digital store having three further locations for storing the position of the reporting aircraft in three co-ordinates digitally. These digital signals after analogue conversion afford ground radar beam elevation by radar frequency variation and beam azimuth control by phase shifting the energy to the elements of the radar aerial array; alternative beam positioning can be by phase shifting only. The radar beam is thus pointed at the aircraft. When an echo is received, the signals from the three further storage locations are read into a comparator also fed with digitized radar-derived position data via a staticiser. On near coincidence of the two sets of position data the comparator sends a signal to cause the staticiser outputs to be fed into an alpha-numeric display device to which is fed also the identity code signal from the first storage location. If objects detected by the radar are not those of interrogated aircraft a signal from the comparator feeds the staticiser outputs to a second alphanumeric display device, together with the identity signal, or to a plan-position display, In a second embodiment the radar aerial rotates at a constant speed, a Cartesian co-ordinate system is employed, the radar operation is independent of the reception of the aircraft position data and " within-pulse " elevation scanning as described in Specification 1.005,379 is utilized.

Title: Submarine cable signalling system
IPC: H04L25/06
Filed: 1942-07-03
Abstract: 555,029. Code telegraphy. COMMERCIAL CABLE CO. July 3, 1942, No. 9210. Convention date, July 10, 1941. [Class 40 (iii)] A circuit for transmitting or repeating signals over a cable comprises means for adding to the signals, before application to the cable, a range of harmonic frequency components of the signals to compensate for the distorting effect of the cable, which attenuates important harmonics. For this purpose pulses, generated synchronously with the signal elements, produce harmonic frequencies in a tuned circuit, these frequencies being added through a transformer to the signals proper, which are delayed slightly. In the system shown in Fig. 1, the dot and dash peckers 2, 3 control locking relays 14, 21 respectively and in parallel with these, pulse-transmitting relays 15, 22. The locking relay 14 or 21 prepares the circuit of the transmitting relay 30 or 31, which is energized after a slight delay by the camcontrolled contact 9 and transmits a positive or negative signal from battery 45 through armatures 46, 47, and secondary of transformer 50 to the apex 51 of the duplex bridge. The pulsetransmitting relay 15 or 22 is also energized, and moves armature 54 or 56 to charge condenser 53 through the primary of transformer 50 and a resistance 55. The effect of the relays 15, 22 is to generate pulses synchronized with the transmitted signals ; the pulses may be regarded as a series of harmonic component frequencies, the tuned circuit 52, 53, 55 selecting a particular range of these frequencies, the width of the range being determined by resistance 55. The selected range of harmonic frequencies is superposed on the transmitted signals via transformer 50. In a modified system, Fig. 2 (not shown), each pulsetransmitting relay is replaced by a pair of relays, each pair controlling a separate tuned circuit, two transformers being included in the transmitting circuit.

Title: Improvements in or relating to grain cleaning and grading apparatus
IPC: B07B1/22
Filed: 1960-03-16
Abstract: 882,411. Rotary screens. SOC. EMILE MAROT. March 16, 1960 [March 16, 1959], No. 9337/60. Class 117. A grain cleaner and grader including a rotary screening drum 2 within a chamber 1 is supplied with grain via a hopper 10 and a shoot 9, and as the granular stream falls from the hopper under the control of an adjustable pivoted shutter 11 it is acted upon by an air stream drawn into an opening 44 by a suction fan 16. The lighter impurities are carried off through a suction passage 13, an expansion chamber 14 and circular apertures 35, Fig. 2, in the fan casing, and through an outlet passage 34. A plate 12, which deflects the incoming air stream, can be adjusted in all directions by crank handles 51, 52, The heavier impurities in the air stream fall on to pivoted vanes 15, normally kept closed by the vacuum produced by the fan, and the weight of the impurities forces the vanes open to allow the material to fall on to an imperforate part 40 of the screening drum from which it passes to an outlet 26. The fan suction is adjusted by opening to a greater or lesser extent apertures 36 leading into the chamber 1; for this purpose a member 17 controls sliding gates 18, and dust particles are carried away from the chamber 1 through those apertures. A motor 19 drives the drum and fan. The drum comprises detachable perforated sections 3, 4, 5 and stirring blades 46, and the perforations are cleaned continuously by rollers 41, 42, 43, which may be of the brush type, which rest on the drum periphery and are driven therefrom. The perforations become progressively larger and the chamber 1 is divided by partitions 6, 6a, 7a &c. into compartments each having an outlet 26, 26a, 27 &c. for the classified product. In the modification of Fig. 5 the feed hopper 61 is vertically slidable on a housing 66 which includes a suction shaft 67, chambers 68, 69 and a suction fan 71. The chambers have pivoted valves 73 opened by the weight of the material thereon. Shutters 75 in the base of the compartment 69 enables the suction in the housing to be adjusted. As shown in Fig. 8 the machine may be mounted on wheels and include a loading hopper 85 from which the grain is fed to the distributer hopper 61 by a bucket elevator 86. A screw type elevator 94, which may be stowed in a horizontal position when inoperative feeds the classified products to a truck. The machine has both an electro motor 99 and a thermal engine 100 either of which may be used to drive the various parts.

Title: Impregnated woods and processes of treating woods
IPC: B27K3/34
Filed: 1925-04-08
Abstract: 254,795. Coolidge, J. R. April 8, 1925. Waterproofing; fireproofing; proofing against bacteria; proofing processes and compositions.- Wood is impregnated with a melted waxy material, for example montan, carnauba or candelilla wax, which is hard and not tacky at temperatures below 130‹ F and sufficiently fluid for impregnation at temperatures not greater than 250‹ F. The wax may be mixed with preserving agents such as creosote, insulating materials such as transil oil, fireproofing agents such as sodium biborate, or colouring agents. The wood may be first immersed in the melted wax at a pressure of one to three atmospheres so that moisture is driven out, and the pressure afterwards raised to force the wax into the wood. At the conclusion of the impregnation the pressure may be maintained while the wax solidifies in the wood, or the temperature may be maintained with reduction of pressure so that some of the included wax will drain away. Wood which has been treated with a fireproofing agent, such as ammonium chloride solution, and dried may afterwards be impregnated with the wax.
