Filed: 1929-04-10
Abstract: 329,779. Menz, H., and Steffen, W. April 10, 1929. No Patent granted (Sealing fee not paid). Pneumatic-tyre pressure gauges with signad and alarm arrangements. - A combined pressure indicator and low-pressure alarm for pneumatic tyres comprises a casing 1 which is fixed in an aperture 16 in the wheel rim 17 at a point opposite to the position of the tyre valve. The casing has a vertical arm housing a piston 3, and a horizontal arm 9 housing a hollow rod 10. The piston is pressed by a spring 12 into engagement with the inner tube 18, which at this point is protected by a pad 19, and the piston rod 5 projects from the lower end of the casing and is furnished with differently coloured rings 6. The rod 10 houses a contact pin 13 pressed outwardly by a spring 11, and at its rear end embraces a reduced part of the piston 3 and carries a pin 20<1> engaging in an inclined slot 4 in the piston. When the inner tube is inflated, the piston is pressed outwardly, the rings 6 indicating the degree of inflation. If the tyre becomes deflated, the piston rises, causing the rod 10 to be projected from the arm 9. The contact pin 13 then engages a contact bridge arranged in an optical or acoustical alarm circuit. In a modification, Fig. 4, the contact pin has an extension 25 formed with a groove 24 in which engages a spring plunger 27 carried in the piston 21. When the tyre becomes deflated, the piston rises, carrying with it the plunger 27. This allows the contact pin to be projected by its spring 28 to engage the contact bridge.

Abstract: 1,026,258. Pipe coupling. FORD MOTOR CO. Ltd. March 18, 1965 [March 25, 1964], No. 11466/65. Heading F2G. In a quickly releasable pipe coupling, more particularly for a tractor implement combination, the coupling comprises a spigot and socket each containing a valve 15 openable upon connection of the coupling, Fig. 3 (not shown), the halves 10, 11 being held together by radially movable balls 24 held in holes in the socket and engaging a recess 25 in the spigot, the balls being held in a locking position by means of a spring-loaded sleeve, the sleeve is fastened to a bracket secured to the tractor and a lever pivotally mounted on the bracket is engageable with one end of the socket so as to move the socket relative to the bracket. As shown in Fig. 1, two such couplings are mounted to the tractor bracket 32 with the socket member 10 uppermost. The coupling halves can be released by raising or lowering the lever end 46 to release the right or left coupling member respectively, the action causing the spigot and socket to move relative to the spring-loaded sleeve to release the balls from the spigot groove and hence release the spigot. The same action can be obtained by an axial pull on the spigot thus releasing the coupling if there is excessive tension on the implement side of the coupling.

Title: Improvements in vehicle wheels
IPC: B60B25/18
Filed: 1931-04-18
Abstract: 383,629. Vehicle wheels. MADER, E., Pr÷sen, near Elsterwerda, Germany. April 18, 1931, No. 11536. [Class 144 (ii).] In a vehicle wheel provided with a detachably longitudinally divided rim having the parts connected together and to the wheel body by double-flanged bolts, the flanges in one position hold the parts together against the pressure of an inflated tyre but can be moved by rotation of the bolts so that at least one flange of each bolt engages a recess in the wheel body and one rim part is released by the bolts and abuts a stop on the wheel body. As shown in Fig. 1, the bolts 5 are provided with flanges 6, 7, extending over 240‹ and 70‹, respectively, which engage recesses 3, 4 and 10, 11 in the rim parts 1, 2 and wheel body 8, the recess 3 being greater than the flange 6. To assemble the tyre on the rim, the part 1 is engaged by the flanges 6 and the tyre placed thereon, the part 2 then being pushed on the bolts which are then rotated 180‹ so that the flanges 7 engage the recesses 4. The rim is now pushed on the sleeve 9 of the wheel body 8 and the bolts rotated 180‹, the rim part 2 then being held against lateral displacement by the stop 12. Fig. 5 is a modification showing the application to a spoke wheel in which equal flanges 17, 18 of bolts 16 engage recesses 14, 19 in the rim part 1 and wheel body 8, respectively, the rim part 2 abutting a stop 12. Accidental rotation of the bolt 16 beyond the position in which the flange 18 engages the recess 19 or the flange 17 engages the recess 14 is prevented by the recess 19 being wider than the recess 15, the rim only being removable by drawing the parts 1, 2 together. Fig. 10 is a further modification showing the application to twin rims, the flanges 17, 18 having inclined surfaces 20, 21, and the stop for the rim part 2 comprising a slotted resilient split-ring 23 having its ends bent to form hooks abutting projections on the part 2.

Abstract: 342,960. Furnace firebridges. GIBSON, W., 75, Somerset Road, Newport, Monmouthshire. April 11, 1930, No. 11546. [Class 51 (i).] The firebridge is formed of sections comprising metal castings 11 of triangular shape with a bulbous apex 15, front and rear flanges 13 extending from the apex to the base with narrowed portions forming air outlet apertures 14 when the sections are placed together, and a web 12 having projecting ridges 16, 17 to form heat exchange surfaces. The sections are assembled upon a plate 9 apertured at 10 so that air from the ashpit 8 passes through the bridge. The apertures 14 at the rear of the bridge are closed by sealing plates 19 the joints between which are covered by wedge plates 20. Passages 18 are left between the flanges 13 at the bulbous portion, forming openings in the crown of the bridge. The projections 16, 17 are of streamline shape and contact with the ridges of the adjacent section to form air passages. The flanges and ridges may extend on both sides of the web 12 or on one side only.

Title: Improvements in or relating to indicating systems for electrical signals particularly for use with radio beacons
IPC: G01S1/02
Filed: 1946-04-15
Abstract: 616,295. Determining peak polarity. DECCA RECORD CO., Ltd., and O'BRIEN, W. J. April 15, 1946, No. 11557. [Class 37] [Also in Group XL (c)] The polarity of the maximum potential peak of an asymmetrical wave is determined by separating from the wave the fundamental and second harmonic components, obtaining two oppositely-phased versions of the second harmonic and determining which of the two versions bears a predetermined phase relation to the fundamental. The method is used to provide a visual indication in a dot-dash equisignal radio beacon receiver. Signals at intermediate frequency from the receiver 57-61, Fig. 4, are detected at 62 to produce a wave such as that indicated at 51<1>, Fig. 5. The alternating component of this wave is fed to amplifiers 69, 70 which are coupled to amplifiers 76, 78 through coupling circuits 75, 77 which are arranged to pass only the second harmonic and fundamental components respectively. The second harmonic component 73, Fig. 5, is fed in push-pull to the anodes of the valves 95, 96 to the control grids of which is fed in parallel the fundamental component 72, Fig. 5. The bias developed by resistance 100 is such that valves 95, 96 are only capable of conducting for short intervals at the positive peaks of the fundamental wave 122, Fig. 6, of duration equal to the duration of half-cycles of the second harmonic waves 120, 120<1>. If the phase of one version 120 of the second harmonic is such that valve 95 conducts, a rectified voltage 124 is obtained across the load resistance 104. The oppositely-phased wave fed to the anode of valve 96 is then as indicated at 121 and no rectified output is developed across load resistance 108. If the phase of the other version of the second harmonic component as shown at 121<1> is (owing to the dash signal predominating over the dot signal) such that valve 96 conducts, then a voltage will be developed across resistance 108 and not across resistance 104. The voltages across these resistances are fed to the control grids of valves 112, 113 which form a bridge circuit with resistances 115, 116, unbalance of the bridge being detected by meter 114. The meter thus deflects to left or right in dependence upon the polarity of the peak, corresponding to the dot signal, of the asymmetrical wave 51<1>.
