IPC: A01C7/06
Filed: 1938-07-18
Abstract: 517,122. Distributers for manures, seeds &c. CZECZOWICZKA, O. July 18, 1938, No. 21288. [Class 6 (i)] A machine for sowing seeds and depositing fertilizers is provided with distributers in the form of rollers 13 having peripheral recesses 14<1>, 15<1>, 16<1> of different sizes, any one of which can be brought into position for use beneath the hopper by turning the roller on its axle 18 and clamping it to the axle in the required position. The rollers are given an oscillatory motion the amplitude or angular position of which can be varied to vary the quantity of seed to be deposited and to vary the proportion between the seed and fertilizer. Fig. 1 shows a machine having a hopper 5 divided by a partition 7 into two compartments for receiving two materials to be deposited. The hopper is hinged at 6 to the frame and contains stirrers 9 driven by lever mechanism from the distributing rollers 13, which are oscillated by links 31, 25, 29 by a cam 27 on the front wheel. The amplitude of the oscillations can be varied by adjusting the links or exchanging the cams, or the extreme angular positions of the rollers can be varied without altering the amplitude of their oscillations. Corrugated vanes 23, 24 extending half the width of the rollers 13, oscillate therewith and serve to distribute the seed &c. laterally. The seed &c. may pass through a sowing share 11 provided with apertures 44, Fig. 7, and adjustable deflecting plates 45 which when the apertures are closed scatter the seed in the furrow and when the apertures are open broadcast it outside the furrow. Blades 48 behind the share mix earth with material passing through the apertures and earth up the rows of seeds.

Title: Improvements in keying arrangements for high frequency signalling systems
IPC: H04L27/04
Filed: 1932-07-29
Abstract: 405,025. Wireless transmitting systems. LORENZ AKT.-GES.,C., 1, Lorenzweg, Tempelhof, Berlin. July 29, 1932, No. 21415. Convention date, Aug. 5, 1931. [Class 40 (v).] To prevent changes of temperature of the anode of a transmitting-valve during keying, and consequent change in electrode capacities and frequency of oscillation, the key is arranged to alter the grid bias as well as to short-circuit the anode oscillatory circuit of the valve. The key operates two relays R1, R2, the contacts of which are shown in the signalling position. Grid bias for the valve R is taken from a potentiometer P connected between a source V and earth, and during signals, resistances W1, W2 are both in the grid circuit. The circuit S is then in oscillation. When the relays R1, R2 are changed over to commence a " space," the negative grid bias is reduced by the cutting out of the resistance W1, and at the same time (or preferably slightly later) the oscillation circuit S is shorted to earth. To reduce changes in the heating of the grid, the valve is arranged to operate with minimum grid current.

Title: An apparatus for stretching fabrics
IPC: D06C29/00
Filed: 1955-07-25
Abstract: 782,003. Finishing fabrics. AETNA-STANDARD ENGINEERING CO. July 25, 1955 [Aug. 16, 1954], No. 21434/55. Class 42 (1). [Also in Groups XI, XXXV and XXXVIII] An apparatus for stretching fabric, e.g. of nylon or polyester resin, while it is travelling through an oven in web form comprises means for drawing the fabric into and out of the oven and stretching the fabric drastically during its passage therethrough, and means between the ends of the oven whereby the fabric is exposed to heat over a distance which is varied automatically in conformity with the current rate of travel of the fabric. Stretching. Fabric is fed by rollers 15-18 to an oven comprising a heating leg 2, a cooling leg 3 and a top structure 4. The fabric is withdrawn from the oven by rollers 31-34 and passed over a dancer roller 39 to a calender or other take-up unit. The movement of roller 39 is used to control the relative speeds of the whole heating and stretching apparatus and the take-up unit. In structure 4, the fabric passes over a roller 43 which is sensitive to fabric tension; movement of roller 43 operates a tension-indicating scale and can also be used to control the speed of rollers 31-34 so as to automatically control the fabric tension. Tachometer rollers 29 and 35, associated respectively with the feed and delivery rollers, drive tachometer generators; the output of these generators may be used to indicate stretch and, as an alternative to the tension control arrangement, to control the degree of stretch by controlling the speed of fabric delivery. Heating. The sides of heating leg 2 are lined with electric heating elements which are screened from the fabric F by adjustable curtains to a degree dependent on the speed of the fabric as measured by tachometer roller 35, and a thermo-pile unit, sensitive to the temperature of the fabric, controls the voltage supplied to the heating elements so as to maintain the fabric temperature opposite unit 54 substantially constant (see Group XI). The air in leg 2 is drawn by a fan out at one side into a duct 114 and fed back at the other side through a duct 122, an air exit 120 being controlled either manually or automatically so as to bleed out sufficient hot air to maintain the air in leg 2 at a desired temperature. Cooling. Cooling air is drawn by a further fan 106 through the open bottom 102 of leg 3, up leg 3 and through top structure 4, and is discharged through an exit 110. If the travel of fabric F stops, vanes 111 move to close exit 110 and a damper opens to allow the cooling air to travel down leg 2 to purge that leg of hot air; simultaneously, the shutters or curtains move to completely screen the heating elements.

Filed: 1973-05-04
Abstract: 1406925 Radio signalling SENSORMATIC ELECTRONICS CORP 4 May 1973 [9 Aug 1972] 21434/73 Heading H4L [Also in Division G4] A surveillance system for detecting the presence in a controlled space of a signal receptor-re-radiator with a mixing capability, e.g. a tag containing a diode-dipole attached to a valuable item, comprises a microwave source arrangement 10-18 for establishing a first electromagnetic field, a source of lower frequency 35 for establishing a second field substantially electrostatic in nature, via a conductor 37, a detector 22 for detecting the presence of the modulation products of the two signal frequencies in the controlled space. In operation, the source 35 in response to pulses from a modulation source 31 produces bursts of oscillation which mix with the microwave signals in the presence of a tag within the controlled space to produce modulation components from which the low frequency signal is recovered at 22. The envelope of the detected signal corresponding to the original modulation signal from source 31 is obtained by an AM detector 25 and used along with a signal from source 31 to activate an alarm 43 via a counter 39. If only a spurious signal is present or if the tag is removed from the controlled space, the counter 39 is reset before the complete count of 39 and alarm is not raised. In the alternative embodiment of Fig. 4 (not shown), the lower frequency source is frequency modulated by the modulating signal and consequently an FM detector is used in place of the AM detector.

In a process for separating solids of differing specific gravities and grain sizes, e.g., coal and shale, raw coal is fed to either (a) a "sink and float," or (b) a cyclone separator in such a quantity that incomplete separation takes place, the unseparated particles being the smaller ones. 'The particles large enough to be separated are screened out of the respective fractions, which now contain the incompletely separated fines. These are, separately or together, further treated in a cyclone giving full separation. The separations are carried out in a suspension which may be magnetite and in this case the magnetite is separated out as shown in Fig. 1. The fine particles are recovered by thickening and the water thus obtained used for washing the screened products. Alternatively, in Fig. 2, the heavy fine particles of the mixture to be separated are used to form the medium. In this case a classification step on the fine heavy fraction recovers the medium and a froth flotation step removes the medium from the light fines.
