Title: Improvements in receiving apparatus for short waves, applicable to ordinary wirelessreceivers
IPC: H04B1/26
Filed: 1932-05-12
Abstract: 405,944. Valve circuits for wireless reception. GROSPAS, P. J., 701, Boulevard Emile Zola, Casablanca, Morocco. May 12, 1932, No. 13699. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 16, 1932]. [Class 40 (v).] A het rodyne receiver employs local oscillations of a fixed frequency, the second detector having a tunable input circuit. Fig. 1 shows the circuit arrangement of an adapter comprising a high-frequency amplifier 2 and triode oscillator 1, the output from which is passed to the terminals of an ordinary radio receiver 6. The inductance 21 in the oscillator plate circuit is coupled to the oscillatory circuit 17, 18 19, 22, which is resonant at either of two frequencies according to the position of the switch 20. By means of switch 24, the adapter is disconnected from the receiver and the aerial circuit is then connected to the latter. The valves are indirectly heated from transformer 25. For each oscillator frequency, determined by switch 20, two wavebands can be received to give beat frequencies lying within the tuning range of the detector circuit of the receiver, in addition to the band available when the aerial is directly connected to the receiver. In a modification, two stages of frequency changing are employed in order further to increase the number of receivable bands (Fig. 3, not shown).

Title: Improvements in centrifugal apparatus for separating and collecting dust or other solid or liquid particles from air and gases
IPC: B04C7/00
Filed: 1936-05-14
Abstract: 475,126. Centrifugal dust-separators. CHELTNAM, C. H. W., CHELTNAM, C. H., and GENERAL ELECTRIC CO., Ltd. May 14, 1936, No. 13704. [Class 23] Apparatus for centrifugal separation of dust from gas consists of one or more separators with axial inlets, arranged with their gas outlets connected to the tangential inlet of a cyclone separator, and with their dust outlets connected to a point in the cyclone separator near its dust outlet. In the form shown, the separator 1 has an axial inlet pipe 3 provided to rotate the entering gas. The separated dust is thrown out through the aperture 5 to the annular collecting belt 6, and the gas passes on to the tangential entry 7 of the cyclone separator 2, which is provided with a dust outlet 11 and a clean gas outlet 14. The dust belt 6 is connected by a conduit 8 to a belt 9 with a number of openings 10 through which the dust from the separator 1 is distributed around the chamber of the second separator. This distribution thus takes place at a position where the gas pressure is lower than that at the inlet 7. The vanes 4 rotate the entering gas in the same direction as the gas in the upper vortex ring in the separator 2. This separator may be of the multiple type described in Specification 406,036.

Title: Lead testing machine for spiral gears
IPC: G01M13/02
Filed: 1934-05-07
Abstract: 428,116. Gauging toothed gears. MARBAIX, G. E., Vincent House, Vincent Square, London.-(Michigan Tool Co. ; 7171, Six Mile Road East, Detroit, Michigan, U.S.A.) May 7, 1934, No. 13801. [Class 106 (ii)] Apparatus for gauging spiral gears &c. comprises a gauging element mounted on a carriage for. movement parallel with the axis of the gear, means for supporting the gear rotatably, and frictional means for rotating the gear interdependently with the axial movements of the carriage. The table 12, mounted in guides on a pedestal 11, is moved by operating a wheel 22 which actuates bevel gear 24, 29 and a screwed shaft 25 engaging a nut 28 depending from the table. The latter carries a sine bar 36 which can be adjusted in guides on the table and set to lie at an angle corresponding to the angle of the screw &c. to be gauged. The sine bar 36 is engaged by a recess in a bracket 52 depending from a second table 13 movable on V-guides and balls at right angles to the first table 12. The table 13 has accurately formed rails 55 on which rest wheels 62 on a shaft 59 journalled in a sleeve 58 forming part of a work carrying member 17 mounted on a shaft 16 supported in bearings in a rearwardly and laterally extending portion 14 of the base 11. A gauging device 18 is formed by two dial gauges 91, the plungers of which engage opposite sides of the long arm of a feeler member 96 pivoted between arms 94. This gauge is adjustably secured to an arm 30 secured to the table 12. The shaft 59 is fitted with a socket to receive a centre 71 carried by an arm 69 which may slide in guides on the work carrier. The screw &c. to be gauged is placed between the centres 64, 71 and the feeler moved to engage the surface of a convolution, the dial being set to zero. The handle 22 is turned and this causes the slide to move and the work to rotate so that if the screw is perfect the gauge still reads zero. Modified forms of support for the gauge are described, one designed to deal with work having a sharp lead angle. U.S.A. Specification 1,898,084 is referred to.

Abstract: 1,105,122. Feeding sheets. EASTMAN KODAK CO. 1 April, 1965 [6 April, 1964], No. 13809/65. Heading B6B. A sheet responsive device for sensing the passage of a sheet as the sheet moves along a given path, comprises a resiliently mounted arm 16, having a curvilinear end portion 18, for intercepting and engaging the leading edge of a sheet 12 and for movement in and along the sheet path from a first position to a second position, and camming means 20 on the arm for disengaging the arm from the sheet when the arm is in the second position. As shown, a sheet 12 is transported upwardly between two opposed sets of conveyer belts 12, 15. The arm 16 has a camming knee 20 just below the curved end 18, and is pulled against two fixed stops 24, 25 by a spring 22. The operating arm 26 of a microswitch 28, which controls the operation of the associated apparatus, is loosely pivotally connected at 30 to the arm 16. When the leading edge of the sheet 12 engages the end 18, the arm 16 is forced upwardly (Fig. 2, not shown) to a position where the knee 20 is engaged by the sheet and cams the end 18 of the arm away from the sheet, whereupon the spring 22 pulls the arm against the stop 25. The switch 28 is operated during the movement of the arm 16 to control, for example, film movement during photographing.
