Title: Improved apparatus for detecting faults in oscillatory current circuits
IPC: G01R31/50
Filed: 1936-11-10
Abstract: 488,645. Electrification detectors. WILLOUGHBY, R. Nov. 10, 1936, No. 30693. [Class 37] In a device for testing and giving a positive indication when an A.C. supply conductor is de-energized, an aerial connected to the grid of a thermionic is disposed near the conductor, and a polarized relay in the valve anode circuit is so arranged that when the grid ceases to receive alternating potentials from the aerial the mean anode current rises and the relay actuates indicating means to signify that the conductor is dead. The aerial 16 is connected through a plug and socket 13, 15 to the grid of a triode 10 the anode circuit of which includes the coil 1d of a polarized relay 1, the moving contact 1c of which is biassed towards contact 1a. When the A.C. conductor under test is " dead and the testing apparatus is energized by closing switches 5, 11, the anode current rises to such a value that the moving contact 1c engages contact 1b thereby energizing the buzzer 4 in series with a lamp 3 to indicate positively that the A.C. conductor is dead. When the A.C. conductor is alive, however, the alternating potentials thereby induced on the grid of the triode 10 are arranged to decrease the mean anode current whereby the moving contact 1c of relay 1 floats between contacts 1a, 1b and no signal is given. At this stage a switch 17 may be closed to earth the grid thereby causing the lamp 3 and buzzer 4 to operate, thus testing the apparatus by simulating the removal of potential from the A.C. conductor under test. Should the batteries 9, 12 or the valve 10 fail or the relay 1 otherwise become de-energized, for example, by opening the test switch 11, contact 1c engages 1a to close an alarm circuit including a lamp 2 and buzzer 4 to indicate that the testing apparatus is at fault,. The alarm circuits may be operated by the relay 1 through further relays. The apparatus is housed in a portable box Figs. 2-4 (not shown), including a recess for storing the aerial and earth connections 16, 14 side compartments for housing the batteries and buzzer and a central compartment housing the valve and relay and including a panel on which the switches 5, 11, 17 are mounted and through which the alarm lamps 2, 3 are visible. Lever arms are also mounted on the panel for manually moving the contact 1c out of contact with 1a or 1b.

Abstract: 982,930. Measuring pressure electrically. BRISTOL AIRCRAFT Ltd. Sept. 25, 1961 [Sept. 6, 1960], No. 30722/60. Heading G1N. In a pressure measuring apparatus a pressure difference between the faces of a peripherally mounted diaphragm causes it to stretch, thereby altering its natural frequency of vibration which is measured. Diaphragm vibrations may be picked up by a microphone or detected capacitively, amplified and fed back to a diaphragm-actuating electromagnet and measured by a frequency meter. As shown (Figs. 1, 4) a diaphragm 1 of magnetic material such as steel is machined integrally with a casing 2 into which fits a unit 22 comprising a base plate 3 carrying a cylinder 4 of insulating material on the end of which is a copper plate 5 forming with the diaphragm 1 a capacitive pick-up and carrying an electromagnet 6. A pressure chamber 13 bolts on to the casing 2. Pick-up plate 5 is connected to amplifier 17 the output of which is fed back to electromagnet 6, lead 11 earthing the casing through a shim 12, causing the amplifier to oscillate at a frequency which is measured by a recorder 18. By applying a second pressure through connection 16, differential pressure may be measured but because the diaphragm 1 is concave with respect to the chamber 13 the greater pressure must be applied through 15. A thickened annular ring on the diaphragm may be used to select the diaphragm vibration frequency mode.

Title: Improvements in the process of making butter, and apparatus therefor
IPC: A01J15/12
Filed: 1926-12-04
Abstract: 262,769. Josefson, J., (Assignee of Wiberg, T. A.). Dec. 14, 1925, [Convention date]. Butter is produced in a continuous manner by feeding cream or whole milk continuously to a rapidly rotating beater in a stationary casing whereby it is subjected to a churning action; the liquid is first treated in a space of substantial width and then it is passed through a constricted passage between the casing and the rotating beater to cause the butter globules to acquire a firm consistency. As shown, the casing comprises two parts 10, 9 secured together by a screwed ring 11 and fixed in the rim of a pan 5 by an eccentric disc 4. At the top the hollow beater has an inlet 19 for the cream &c. from a receptacle 20, and at the lower end there is a tubular extension 23 which fits over the upper portion of the driving-spindle 2 and is coupled thereto by a cross-pin. The radial vanes 25 of the beater throw the cream outwards below an annular extension 26 and against the ribbed wall 14 of the casing. The mass ascends, passes over a horizontal portion 27 of the beater and between ribs 29, 18, and then reaches the constricted passage between the casing and a smooth part 30 of the beater. Ribs 31 above the part 30 eject the butter into the outlet 16, and still higher radial ribs 32 prevent escape of butter through the gap between the tube 19 and the casing. Also, instead of the cream being fed from above, it may be sucked up by the beater which is then made to taper towards the bottom. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of the apparatus in connection with separators having a suspended drum, and the attachment of the beater directly to a separator drum, the casing being fixed to the stand. This subject-matter does not appear in the Specification as accepted.

Abstract: 814,679. Commutators for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO. Ltd. Oct. 4, 1957 [Oct. 9, 1956], No. 30807/56. Class 35. [Also in Group XXII] A method of constructing an electrical commutator, in which the undercut insulating spacer strips that separate the commutator segments have narrow longitudinal slots 1 parallel to and adjacent the outer surface of the commutator, with the outer edges of the slots within said surface, comprises assembling the elements and then machining said surface with the outer edges of the segments supported by the material of the spacers lying outside the slots. The assembly is first roughly machined, each spacer being reduced to a line A-A<SP>1</SP> and is then mounted in a clamping means, for example two rings of V-shape cross-section (not shown) which locate'in V-shaped notches in the segments. The commutator is again machined to ensure concentricity with the clamping means and reduce each spacer to a line B-B<SP>1</SP> along the outer edge of the slot. The slot being closed at each end, the insulation extends to the periphery of the commutator at both ends after machining and thus leaves no gaps into which solder can run when the risers (not shown) are connected at one end of the commutator. In one modification the slot is open at one end and in another the long slot is replaced by two shorter slots to provide two brush tracks.
