Abstract: 626,563. Tumbler driers. LOVELL MANUFACTURING CO. June 9, 1947, No. 15156. Convention date, June 28, 1946. [Class 34(ii)] A tumbler type clothes drier has a cabinet 1 and a drum 5 driven by a motor 6 and surrounded by a casing 13 which has a trough 16 with a connection 17 to the inlet chamber 18 for the centrifugal fan 19. Lint in the air drawn through the drum by the fan 19 is collected in the cylindrical casing 22 and the removable re-entrant cylinder screen 23 having its inner end 24 adjacent the fan 19 which has a hub 25 and blades 26 and is mounted on a shaft 27. Air and the entrained lint are discharged by the fan in the form of a vortex spiraling around the screen 23 towards the front of the cabinet and due to the rotary motion of the air, lint tends to felt around the front end of screen 28. As the quantity of lint collected increases, the back pressure builds up and finally a considerable part of the air flows directly through the open end 24 of the screen, the presence of lint on the floor warning the operator that the lint trap is overloaded. In a modification, Fig. 4, the lint trap casing 22a extends the entire depth of the base and the air is circulated through the drier by a centrifugal fan having casing 31 connected to trough 16 and an impeller 32 driven by a belt from the motor 6, the fan having its discharge 34 connected tangentially to the casing 22a. Space 35 provides a bye-pass passage.

Title: Improvements in and relating to band resistances for the continous regulation of heavy currents
IPC: H01C10/28
Filed: 1936-06-06
Abstract: 476,055. Variable resistances. AKT.- GES. BROWN, BOVERI, & CIE. June 6, 1936, No. 15904. Convention date, July 25, 1935. Addition to 467,574. [Class 37] The band resistance according to the parent Specification is so arranged in an electrical circuit that current flows only in the direction from the contact devices to the band, and the contact devices are preferably in the form of rollers the contacting surfaces of which are made of metal having an oxide of comparatively high conductivity, e.g. silver. The resistance spiral a is held between rings d<1>, d<2> by insulating bolts b and current is led through a bolt c<2> to the conducting ring d<1>, which serves as a slip ring for contact brushes 20 of metallized carbon. The current flows from brushes 20 through guide rods g<1>, g<2> and the contact rollers e<1>, e<2> to the resistance band a and thence to the connection c<2>. The bearing bushes of the rollers are also formed of metallized carbon and are provided with cooling ribs. The rollers are given a silver coating 23 which is rolled on at the bottom of the guiding groove. Rollers e<1>, e<2> are mounted to engage both edges of the resistance band, all the rollers bearing thereon with an equal pressure, and for this purpose the guide rods g<1>, g<2> on each side of the band are mounted in a support 26 symmetrically about a pivot pin 24 which is itself supported on a member 25 pivoted about a pin 27, the two members 25 situated one on each side of the band being pressed inwards against the band by a common spring o. The contact making device turns about the shaft n. When several spiral resistance bands are mounted adjacent each other on a common axis, the spirals are formed alternately left-handed and right-handed so that the rollers of one resistance run inwardly while those of the next run outwardly with the same direction of rotation of the driving shaft. The beginnings and ends of adjacent spirals are also offset with respect to one another and the resistances are arranged in an air passage, the arrangement described rendering the cooling more efficient.

Abstract: 475,369. Magnetic tests. BARNES, W. C., and KEEVIL, H. W. June 6, 1936, No. 15910. Convention date, June 8, 1935. [Class 37] An energizing magnetic flux is set up progressively along a relatively movable body, and, after its removal due to the relative movement between the body and the magnetizing device, the residual magnetism is explored progressively for the detection of flaws. In one arrangement, Fig. 1, a test carriage is provided with an energizing magnet unit 62 and a detector unit 80 both units being adapted to receive a small movement for lifting them from the rails 71 under test. Detector cores 97, Fig. 7, are connected electrically in opposition and the induced currents are fed to recorders through thermionic amplifiers. The rails can be energized longitudinally or transversely and the detector units correspondingly arranged. Energization by passage of current through the rail can also be effected. Horizontal and vertical components of the residual magnetic field may be indicated and the detector pick-ups arranged at a suitable angle for this purpose. Separate energization and detector cars can be employed. The detector unit may include a cathode-ray tube 185, Fig. 30, or balanced bismuth resistors 198, 199, Fig. 32. Piezo-electric, carbon-pile, condenser and ribbon microphones, and the Hall effect can all be used as forms of detector mechanism, Fig. 38 showing one way of utilizing the Hall effect with plates 260.

Title: Improvements in or relating to television d.c. restoration circuit arrangements
Inventor: NIXON JOHN ESMONDE ARTHUR
IPC: H04N5/16
Filed: 1952-06-24
Abstract: 736,411. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 12,1953 [June 24, 1952], No. 15914/52. Class 40 (3). In a D.C. restoration circuit of the type in which a condenser is charged via a unilaterally conducting device during synchronizing intervals and is discharged via a resistance between the synchronizing intervals the waveform to be restored is applied to both ends of the resistance. This arrangement produces an improvement in the accuracy of the restored D.C. level by making the condenser discharge current independent of variations in the picture signal voltage so that the voltage across the unilaterally conducting device whilst conducting (i.e. during synchronizing intervals) does not vary with the picture signal content of the preceding line. Fig. 3 shows one embodiment in which in addition to the elements C, D and R of a conventional D.C. restorer additional elements C<SP>1</SP>, D<SP>1</SP> and R<SP>1</SP> are connected as shown, the reference potentials RP and RP<SP>1</SP> and the biasing potential B being such that when the direction of current flow through D is charging C the current through R discharges C. In accordance with the invention, the input wave (positively going) which is supplied to the circuit via terminal IN is effective at both ends of resistor R so that the current flowing through R due to the picture signal is zero. In this condition the discharge of condenser C is unaffected by the picture signal voltage and since it is therefore discharged by the same amount during each inter-synchronizing signal period the voltage across the diode D when conducting during synchronizing signal periods (due to its inherent finite resistance) will be constant. The " tips " of the synchronizing signals are therefore brought to a constant level approximating to the reference potential RP. In a modification (Fig. 4) an additional resistance R" causes diode D<SP>1</SP> to restore to a different potential from that to which diode D restores and so develops a constant voltage across R which enables this resistance to be made larger whilst still carrying sufficient current for correct operation. In a modification of this arrangement R" is returned to the reference potential RP and resistance R<SP>1</SP> is connected to a reference potential which is negative with respect to RP by an amount equal to the peak signal amplitude (Fig. 6, not shown). Fig. 5 shows a preferred embodiment in which the application of the waveform to be restored to both ends of the resistor R is effected simply by shunting condenser C by means of the resistor.
