Filed: 1939-10-12
Abstract: 535,078. Filter circuits ; wireless receivers ; valve circuits for receiving high-frequency signals. HAZELTINE CORPORATION. Oct. 12, 1939, No. 27766. Convention date, Oct. 29, 1938. [Classes 40 (iii) and 40 (v)] A filter, e.g. for the input stage of a television receiver, comprises a pair of circuits tunable by means of inductance and capacity respectively and coupled by means such that the co-efficient of coupling varies inversely as the frequency. In one arrangement, Fig. 1, the filter takes the form of a constant-k network terminated by resistances equal to its image impedance which resistances may be the inherent resistances of parts of the circuit. In a modification, Fig. 5, similar circuits are coupled by a capacity Cc. The unwanted inductance L<SP>1</SP>C<SP>1</SP> of the coupling branch in this arrangement or the unwanted capacity of the inductance L1 may be compensated by a condenser Cc<SP>11</SP> and the unwanted capacity of L 2  may be compensated by a condenser in series with the coupling condenser, Fig. 8, (not shown). In another arrangement, Fig. 6, in which anti-resonant circuits are connected in parallel through a coupling inductance LC, the unwanted capacity Cc<SP>1</SP> of the inductance may be compensated by a common inductance L<SP>11</SP>c. Formulae are given for obtaining the sizes of the coupling and compensating elements. In the application to a wireless receiver shown in Fig. 9 the aerial is coupled by a symmetrical transformer arrangement and the filter is tuned in steps by switches. To reduce the input conductance of the first amplifier tube, negative feed back is provided by an inductance 42 in the screen circuit coacting with the inherent capacity between the screen and signal grids, or by a transformer coupling between the cathode and grid circuits.

Title: Improvements in or relating to electric machines for working under liquid
IPC: H02K5/132
Filed: 1925-11-06
Abstract: 242,660. Siemens - Schuckertwerke Ges. Nov. 7, 1924, [Convention date]. Casings; alternating-current motors. -A motor for submersion under liquid, for example for pumping oil or water from bore holes, has a tank for collecting any liquid which may enter where the shaft passes through the casing and a valve which shuts off the shaft passage from the windings &c. when the armature is stationary, the valve being tightly mounted on the shaft and movable longitudinally therewith so as normally to be closed by the weight of the motor and to be lifted from its seat when the machine is working. Figs. 1 and 2 show an induction motor for attachment to a pump at 34 and comprising rotor and stator structures 5, 2 mounted in a composite tubular casing the upper part of which is shut off by the members 23, 24 containing the shaft bearing 7 and packings 18, 19. The lower end of the casing consists of a tank 32 separated from the body portion by members 25, 26 which contain the lower bearings 8, 17 and packings 20, 21, 22. By means of a centrifugal governor 12, which rotates with the shaft, the shaft and armature are raised when they rotate, thereby lifting from its seating a circular valve 35 which is securely fixed on the shaft and which, as long as the armature is at rest, forms a tight closure to a chamber 38. Any liquid which may enter through the stuffing-box 33 while the machine is at rest, or which enters while it is running, is allowed to pass under the valve from the space 38, through a port 39, pipe 40 and passages 42, 44 into the tank 32, from which it is ejected by a bilge pump 47 through an outlet closed by a valve 48. The valve 35 may, alternatively, be arranged above the stuffing-box 33. The Specification as open to inspection under Sect. 91 (3) (a), states that the upward magnetic pull of the stator on the rotor may be used for raising the rotor. Also that the pump may be coupled to the machine shaft when the liquid reaches a certain height in the tank and uncoupled when it sinks owing to the liquid being pumped out. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in apparatus for malting grain
Inventor: PARKER WILLIAM
IPC: C12C1/15
Filed: 1965-07-02
Abstract: 1,129,533. Mixing granular materials. VICKERS Ltd. 1 June, 1966 [2 July, 1965], No. 28236/65. Heading B1C. [Also in Division C6] A malting apparatus incorporates an enclosed, stationary vessel 1, Figs. 4 and 6, a perforated false floor 9, a connection 17 for supplying and draining steeping liquor to and from the charge space 2, connections to an air conditioning plant or to a kilning plant whereby humid conditioned air or dry heated air may be passed through the charge of grain (at the appropriate stage in malting) in either direction, a stirrer 50 operative over substantially the whole area of the charge space 2, and hinged doors 10a in the false floor 9 through which the vessel can be discharged. Barley is delivered into the charge space 2 through openings in the top of the vessel afforded by chain-operated slides. After the malting, a screw conveyer 11 is wheeled in beneath the doors 10a to facilitate discharge of the malt after the doors have been opened. Rotary ploughs 65 push the malted grain into the elongated opening 10. Any overflow of the steeping liquor is drained away through a skimming box 23. The rotary malt stirrer 50 travels sequentially along a revolving frame structure 33. The rotary motion of spindle 29 is imparted through a clutch to a radial shaft which in turn drives a sprocket 38, holding the frame structure, over the pins of a circumferential track 37. The carriage of the stirrer is slidably mounted on rails along the frame structure and the radial position of the carriage therealong is adjusted by a hand wheel through the intermediary of an arm which engages a chain drive. The spindle is actuated by an electric motor 32. The single helical conveyer (stirrer) 50 may be replaced by two such conveyers two pitches apart, and the helical conveyer(s) and the carriage may have individual motors. The plough mechanism incorporates two blades 65 disposed end to end and together extending across substantially the full diameter of the vessel. The two blades 65 are supported and rotated through link chains 66a which are attached to arms 66 secured to the centre spindle 29 by a releasable clutch 67, 67a. The chains (at the lower end) are attached to levers 68 which are secured edgewise to the backs of the respective plough blades 65 and provide the bearings for plough spindles 69 carried by a collar 71 and upon which the blades can tilt. During the discharging of the green malt, the stirrer is brought to a position directly above the elongated opening and the plough arms are rotated to and fro through an angle of 180‹. If, however, the helical stirrers are completely removed from the vessel prior to the discharging, then the ploughs may be arranged to rotate continuously without any reversing. The plough mechanism, when it is not in use, is lifted manually to an uppermost position in which it can be hooked to the frame structure by a hook 72.
