Filed: 1937-12-01
Abstract: 506,660. Modulating systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and DITCHAM, W. T. Dec. 1, 1937, No. 33252. [Class 40 (v)] To obtain high efficiency in the power amplifier of a modulated carrier wave transmitter, the carrier and side bands are fed to the load by separate valves. The valve 6, which is biassed to operate as a Class C amplifier and whose anode is connected to the high tension supply through the audio-frequency high impedance 9, feeds pure carrier from the source 1 to the load 15 through the tuned circuit 12, 13. A second valve 16 connected to the same high tension source is also connected to the tuned circuit 12, 13, at such a point that the carrier frequency voltage 'on its anode is about half that on the anode of valve 6. A steady bias 22 is applied to the grid of valve 16, sufficient to produce anode current cut-off for the particular D.C. anode potential employed. Carrier frequency is applied in phase opposition to two parallel amplifiers 25, 26, modulation from 29 being employed to modulate the oscillations in one amplifier. The outputs of the amplifiers 25, 26, are combined in opposition in the carrier frequency tuned circuit 27 which supplies the side bands to the grid of valve 16. An initial unbalance in the amplifiers 25, 26, is provided so that a carrier frequency output of such phase and amplitude is applied to valve 16 that its anode current is approximately zero for oscillations in circuit 12, 13, corresponding to the unmodulated condition. In a modification, valves 6 and 16 .are both connected to the same point in tuned circuit 12, 13, but the anode of 16 is supplied from a source of potential of about twice the value of that from which the anode of valve 6 is supplied. Specification 326,375, [Class 40 (v)], is referred to.

Title: Drum storage look-up device
IPC: G06F7/22
Filed: 1955-11-22
Abstract: 805,663. Electric digital - data - storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 22, 1955 [Nov. 24, 1954], No. 33390/55. Class 106 (1). In a look-up device for obtaining a required information word from a plurality of words, each of which has a " tag " portion which distinguishes it from every other word and which words are stored in an ascending or descending order of tags on a magnetic drum having (2<SP>n</SP> - 1) storage tracks (n being an integer) the tag of the required word is registered in a circulating oneword store, constituted by part of a temporary storage track on the drum, and is compared first with the tags of all the words of the middle track of the drum, then with those from the middle track of either the " higher " half or the " lower " half of the drum depending upon the result of the first comparison, then with those from the middle track of either the adjacent " higher quarter or the adjacent " lower " quarter of the drum depending upon the result of the second comparison and so on until the required word is found. The basic unit comprises two diodes 48, 57, Fig. 4, and two inverters 40 and 56 to which the tags to be compared from the track being searched and the one-word register respectively are fed simultaneously in the form of 6-digit binary numbers-highest denomination first-and is so arranged that the potential of a point 47 only rises when a " one " is fed to inverter 56 and a " zero " to inverter 40. Thus, if the tag applied to inverter 56 is the greater then triode 64 conducts and causes a relay (not shown) to pick-up and hold. If the number fed to inverter 56 is the smaller there is also the possibility of triode 64 becoming conductive since the number fed to inverter 56, even though being the smaller, may have a digit in one of its lower denominations greater than that in the corresponding denomination of the number applied to inverter 40. This possibility is prevented by employing a second basic unit, as shown in Fig. 4, oppositely connected to the source of tags; then this second unit will produce an output, i.e. its triode 64 will conduct, when the number fed to inverter 56 of the first unit is the smaller, and the output is used (though not shown) to block the output tube 64 of the first unit.

A graduated tape 34 is housed on a spring roller in a casing 35, and is secured at its lower end to a hub 20 on the carrier 16. In a modification, Fig. 4 (not shown), the carrier is curved downwardly to form a U-shaped receiver for the bottom of a garment, the stapling mechanism being inverted, and the post carries graduation marks, the graduated tape being dispensed with. In another modification, the rotatable shaft is replaced by a rack and pinion. In a further modification, Fig. 6, the stapling mechanism is replaced by a marking disc 53, e.g., of chalk which together with a friction roller 52 and cup 54 is mounted on a shaft 51 rotated from a shaft 66, the roller 52 and cup 54 being in frictional driving contact with an impression roll 55 secured to a shaft 56 mounted in a frame 57, and carrying impression points 58, the latter acting in conjunction with the disc 53 to leave an impression on the garment 33. The roll 55 is moved towards or away from the roller 52 and cup 54 by a finger lever 65 acting in conjunction with springs 59 and rods 60. In a variation of this form, Fig. 11 (not shown), the carrier is formed with two pairs of downwardly extending supports through which the rods are passed for connection to the frame carrying the impression roll. In another modification, Fig. 14, the base member 12 is caused to move in an oval path about the platform, and the stapling mechanism 97 is slidingly mounted on plates 96 secured to a table 94, the stapling mechanism being operated by a plunger 30. The measuring tape 105 is of concavo-convex form, and passed over a roller mounted in the top of the post 14 being secured at its other end to the table 94. The magazine 107 for the staples contains powdered chalk or the like so that the staples are powdered when passed through the garment. In a further modification, means are provided for applying marking material, e.g., chalk to the cross bars of the staples.

Title: Equipment for the combustion of oils of differing viscosity, by means of atomization in light-oil burners
IPC: F23D11/44
Filed: 1959-10-05
Abstract: 924,161. Burners. F. DRESING. Oct. 5, 1959 [Oct. 10, 1958], No. 33638/59. Class 75 (1). Equipment for the combustion of oils of varying viscosity by means of atomization comprises an oil flow pipe and an oil return pipe leading respectively to and from an atomizer nozzle, pumping means for circulating oil through the pipes means for heating the circulating oil, the nozzle communicating with the pipes by way of a non-return valve adapted to permit oil flow to the nozzle only when the pressure of the circulating oil exceeds a predetermined value and a valve in the return pipe which valve includes a closure member mounted on a vibrating component adapted to be set in oscillation by oil flowing through the valve, the arrangement being such that the oscillations of small amplitude cause throttling of the oil flow while when oscillations of increasing magnitude bring the closure member into contact with the associated valve seat the oscillations cease and the closure member is held on the valve seat by the oil pressure in the pipe upstream of the member so as to close the return pipe. The vibrating component in the return flow pipe 1 comprises a bar 3 mounted at one end in blocks 6, 7 with oblique contacting surfaces adjustably positioned by a screw 8. A further screw 19 contacts the bar and is adjustable according to the viscosity of the oil indicated by the indicator 21 so that the vibrations increase to engage an enlarged member 4 in an aperture 5 in the pipe and so cuts off the return flow when the predetermined viscosity for the preheated oil has been attained. The nozzle tip has a non-return valve which comprises a valve shaft 10 with longitudinal recesses 15, a radial recess 14, a piston 13 and a conical member 12 which is urged against the valve seating by a spring 16. The valve may vibrate in resonance with small vibrations of the bar and intermittently close allowing a reduced flow of oil to the nozzle until the vibrations increase to the extent of the member 4, closing the aperture 5 and then the non- return valve opens completely to supply full oil pressure to the nozzle. By this means explosive ignition of the oil is prevented. The surface 18 of the valve may be bevelled. The bar 4 may be made of bimetal and a further bimetal bar 9 may be mounted in the block so that by its contraction as the temperature decreases it lifts the member 4 from the aperture in which it may be retained by suction. During the initial period until the non-return valve opens completely, a switch in front of the pump puts out of action controlling gear for putting the pump out of action should the flame fail until atomization of the oil begins. The controlling gear may be light responsive.
