Title: Improvements in frequency and space modulation systems for carrier-wave signalling
IPC: H03C3/34
Filed: 1939-11-10
Abstract: 534,757. Frequency and phase modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 10, 1939, No. 29795. Convention date, Nov. 12, 1938. [Classes 39 (i) and 40 (v)] [Also in Group XXXIX] Frequency or phase modulated waves are produced by (a) amplitude-modulating the carrier by a current derived from the signal, (b) amplitude-modulating the carrier displaced in phase by 90 degrees by a current derived from the signal and also displaced in phase by 90 degrees, and (c) combining the two outputs to produce a wave represented by sin (wt+ m sin Át), where w and are the angular frequencies of the carrier and signal respectively. For producing phase modulation, m is constant, and for producing frequency modulation m is equal to a constant divided by nÁ. As shown in Fig. 1, the carrier source 1 supplies waves in quadrature to the modulators 3, 4 the combined output of which feeds the aerial 9. The signal m sin Át derived from a microphone 18 is applied across two deflecting plates 16, 17 of a cathode-ray tube 10. The other pair of plates are connected to an ultra shortwave source 15 by which the luminous spot is caused to traverse a vertical line on the fluorescent screen 12. The screen is divided into two sections by a horizontal opaque plate 28, and each section is partially blacked out in the form of two sine curves 30, 31 in quadrature relation as shown in Fig. 2. As the vertical line 29 is traversed to and fro with a horizontal displacement represented by m sin Át. its luminous intercepts on the respective sections of the screen are represented respectively by sin(m sin Át) and cos(m sin Át). This light is focused by lenses 22, 25 on photocells 23, 26 which through amplifiers supply corresponding voltages to the modulators 3, 4. In a modification, Fig. 3 (not shown), strips of varying translucence are employed in place of the opaque strips bounded by sine curves. In Fig. 4 the fluorescent screen is replaced by grid targets having their vertical elements 36, 37 displaced by a quarter of the distance between them. The targets are connected to amplifiers 40, 41 feeding the respective modulators 3, 4. In order to produce frequency modulation, the microphone currents are fed to the deflecting plates 16, 17, Fig. 1, across a condenser 21 in series with a resistance 20, so that the voltage on the plates varies inversely as the frequency of the signal current. Specification 416,707 is referred to.

Title: Improvements in apparatus for filling bottles and the like containers with gas charged liquids
IPC: B67C3/26
Filed: 1923-11-27
Abstract: 207,557. Soc. Anon. de Construction de MatÚriel d'Alimentation et de Bouchage MÚtallique. Nov. 27, 1922, [Convention date]. Bottling.-In apparatus for filling bottles &c. with gas-charged liquids, and particularly apparatus such as described in Specification 190,158, the delivery tube is provided with grooves so arranged as to prevent splashing of the liquid against the bottle neck, and a distributor is arranged to supply liquid at a constant pressure without the aid of regulating springs. In the delivery tube, which comprises an outer tube 25, Fig. 1, soldered internally to a mould tube 26 closing the passage 29 to the return of air, inclined pasages 29<1> are provided in the delivery head so that the air in the bottle passes between the jets and escapes to the opening 30. The distributor comprises a cylinder 32, Fig. 4, for containing a reserve of saturated liquid, with an emptying cock 33, a level gauge 34, and a pressure gauge 35. The cover 36 carries a support 37 for a lever 39 at the end of which is a washer 39<1> adapted to close an outlet 38<1>. The lever is formed in the centre as a ring 41 encircling a pipe 40 leading to the inlet of the bottling-apparatus. A float 42 slides upon the pipe 40 and is adapted, in the upper position, to bear against and operate the lever 39. A pin 44, passing through notches 43<1> in a sleeve 43 on the float, limits the veretical movement. The float is made of thin material and pipes 45 are provided to equalize the pressure within and without. In use, the cock 33 and the outlet 40 are closed and the cock 38 opened.. Liquid, is admitted at 54<1> past a valve 53 until it reaches the lower end of the. gauge 34, when the cock 38 is closed. The float comes into action and closes the outlet 38<1> bv means of the washer 39<1> on the lever 39. The cock 38 is again opened and as the pressure in the distributor rises, a flexible diaphragm 48 forming the base is distended downwards against the action of a lever system 58, 62, 60, weighted at 64, and a disc 52 carried on rods 51 forces the valve 53 back on the seat when the internal pressure balances the weight 64. The pipe 40 leading to the bottling-apparatus is opened and liquid escapes, causing the float to descend. The outlet 38<1> is thus opened and the pressure falls until the diaphragm 48 rises and releases the valve 53, admitting more. saturated liquid, and the operation proceeds thereafter in a continuous manner.

Abstract: 1,165,525. Logic circuit. INTERNATIONAL BUSINESS MACHINES CORP. 24 June, 1968 [22 Aug., 1967], No. 30070/68. Heading H3T. In a current steered logic circuit performing the inverse of the exclusive-OR function, first and second current switches including for example transistors 1, 4 and 2, 6, each receive a separate input signal A, B and a reference signal, and each switch provides a complementary pair of outputs (at the collectors) one or other output of each pair providing a current path according to the state of the respective input signal A or B; and first and second current sources such as transistors 23, 25 feeding a common output 27 are provided, the first transistor 23 being connected to one output of each complementary pair at 12, and the second transistor 35 being connected to the second output of each pair at 29. The current switches are long-tailed pairs having emitter resistors 8, 10; and the connection of the current source transistors 23, 35 to the collectors of transistors 1, 2 and 4, 6 are made via current limiting transistors 19, 31 respectively, which serve to prevent the switching transistors 1, 2, 4, 6 from saturating. If signals A and B are present, transistors 1 and 2 conduct and transistors 4 and 6 do not, so that transistor 31 is non-conducting and the base 36 of transistor 35 and also its emitter 38 and the output 27 are held positive by resistors 32, 33. If A and B are both absent, transistors 4 and 6 conduct and transistors 1 and 2 do not so that transistor 19 is non conductive and the transistor 23 holds the output 27 positive. If however A and B are different, both transistors 19, 31 conduct and the output 27 falls. Thus the output represents A.B + A.B.
