Title: Improved Anti-skid Attachments for the Wheels of Automobiles.
Inventor: DAVIES DAVID PERCIVAL
IPC: B60B15/04
Filed: 1917-03-10
Abstract: 113,996. Davies, D. P. March 10, 1917. Slipping - preventing attachments to wheels.-Relates to devices in which road-grips, normally in. operative, are projected to engage the ground either by manual operation or automatically on the occurrence of slipping or skidding. Figs. 1 and 2 show the non- automatic form in which a series of ribbed treads D have projections engaging spiral grooves in rings E F mounted on a ring A fixed to, and rotating with, the road wheel. Springs I normally maintain the parts in the position shown, i.e. with the treads D retracted, means being provided for braking the rings E F to cause the road wheel to over-run the rings, with the result that the treads Dare forced radially outwards to engage the road. For this purpose, a ring J is thrown into engagement with the coned surface of the ring E F by means of a collar L threaded on a fixed flanged ring G. The device may be locked in any operative position by means of a toothed ring H which is caused to engage a rack on the ring E F by the movement of a ring K disposed similarly to the ring M. The rings L, K are formed with racks engaged by pinions N, M which are operated by the driver through crank mechanism S, R. Figs. 3 and 4 show the automatic form of the device in which a set of spring-pressed rods J, normally in road-contact, are disposed between two sets of ribbed treads D mounted as shown in Figs. 1 and 2. The rods &c. J are carried by the outer member of a two-part ring K K, the two parts of which have a toothed engagement and are capable of slight relative axial displacement. Plates Z fitted on springs in recesses in the inner part are formed with studs working in helical grooves in a ring C which, together with the main rings A, B, is fixed to the wheel. On the occurrence of circumferential or side slip, the inner member of the ring K K is displaced axially so as to be forced into frictional engagement with one or other of the rings E, F, G, H. The consequent retardation of such ring results in the projection of the corresponding set of treads D, as described with reference to Figs. 1 and 2.

Abstract: 943,251. Electromagnetic relays. ENGLISH ELECTRIC CO. Ltd. Jan. 15, 1960 [Jan. 23, 1959], No. 2523/59. Heading H2B. In a relay with a disc or drum-type rotor having a winding disposed thereon, the winding a plurality of electrically parallel paths which pass between the poles of a magnet as it rotates. The winding may be formed on the rotor by printed circuit technique, but as shown in Fig. 1, slots are punched out of the rotor so that the current passes from area a radially outwards to the area b and the leads are arranged so that the current paths are approximately equal so that equal currents flow in the spokes, which may be of high resistance to assist the equalization of current. The paths may be of graded widths so as to compensate for the restoring spring. With the drive magnet in series with the rotor winding the relay has a characteristic I<SP>2</SP>t = k and with a permanent magnet as a drive magnet the relay has a characteristic It = k. In Fig. 3 the current paths on the drum are sloped to produce uniform rotation. Alternatively (Fig. 4a), the rotor 12 may be mounted between magnet poles 10 shaped so that the spokes 12b move in a uniform field whereas the rim 12c moves only partially between the poles to produce eddy-current damping. In Fig. 5 the rotor 29 is slotted between parts 29a, 29b to produce the parallel paths for current passing between springs 27, 28 and the core parts 21a or 21d may be permanent magnets if the coil 22 is omitted. The poles may be notched as at 32 to produce a damping effect. To increase the current carrying capacity of the lead-in springs a helical spring and a silver strip winding on to a spiral cam may be used (Fig. 2, not shown). Specification 941,382 is referred to.

Title: Method and apparatus for the automatic manufacture of duct  elements
IPC: B21C37/20
Filed: 1973-01-17
Abstract: 1389184 Making corrugated ducts KARL MEINIG KG 17 Jan 1973 [26 Jan 1972] 2527/73 Headings B3A and B3E [Also in Division F2] A method of manufacturing sheet-metal ducts, Fig. 8, of rectangular cross-section comprises feeding strip 3b from a coil 3, Fig. 1, to a shaping unit B to produce a rolled flange section 3c, Fig. 3, on both edges of the strip; providing incisions in the flange at distances corresponding to the final dimensions of the duct, bending the strip in a folding unit C to form a rectangle (3e)- (3h), Fig. 7e (not shown), and cutting the formed duct from the strip. The uncoiled strip is straightened using rollers 6 and provided with triangular flange sections 3c by rollers 4. Additional rollers (5), Fig. 2 (not shown), impart a shallow zig-zag profile to the strip to produce reinforcing tines 21, 22 in the finished duct. The sections are spot welded at 7 and the strip fed by rollers 4, via driven guide rollers 8, to unit C where an overlap 3d, Fig. 3, is produced. The strip is clamped by upper jaw 10 and circular saws 12 make incisions in the sections 3c. The section 3c attached to overlap 3d is cut off using sheet-metal shears (not shown). The overlap is then folded and the sheet fed to a limit stop 14 adjusted according to the required dimensions of the finished duct. A switch 14a stops the feed and folding of the strip begins. Upper jaw 10 is again lowered, saws 12 raised into their cutting position and support arms 13 and bending jaw 11 swivelled about edge 9a. The upper jaw is disengaged and the feed restarted until a further folding step is required to form a duct of rectangular section, Fig. 7a-7e (not shown). Upon completion of four bending operations the cutting-off operation is automatically triggered by a control device. The duct is cut off the strip using a cutting roller 15a which is lowered into a gap between edges 9a, 11a and rotating saw blades 12a are raised to cut through the strip section. The overlap 3d may be secured to adjacent wall section (3h) by a rolled seam or a projection or spot welding machine. Corner angle pieces (16), (18), Figs. 9, 10 (not shown), 19, 20 are inserted at the corners of the duct. This may include spot welding of angle pieces (16), (18) to the peripheries of the flange section 3c or introduction of pieces 19, 20 into the cavities of the flange section. Outer ends (19c), (20c), Figs. 11, 12 (not shown), prevent lugs (19a), (20a) sliding into the cavities. Connecting screws (not shown) may be used to rigidly fix the angle pieces.

Title: Improvements in or relating to the automatic control of electric circuit breakers
Inventor: WARD HUGH JENNINGS
IPC: H02H3/07
Filed: 1945-02-02
Abstract: 645.333. Protective cut-out systems. STANDARD TELEPHONES & CABLES. Ltd. Feb. 2, 1945, No. 2663. [Class 38 (v)] In an automatic circuit-breaker reclosing eauipment, provision is made whereby after four automatic reclosures consequent upon the occurence of a prolonged fault, the reclosing mechanism is locked out and the circuit-breaker remains open. When the breaker first trips, auxiliary contacts BAC change over releasing a relay AP and energizes a slow release relay G in the breaker control circuit, whereupon contact ap3 in a timing circuit energizes a timing condenser QC which begins to charge until at the firing voltage of a cold cathode tube CCT, a relay P is energized. A relay A in a relay counting-train is thus operated over closed contacts g1, p1. aa2. thereby closing contact a3 and operating a breaker closing relay CL. Contacts BAC are restored and relay AP re-energized, releasing relay P and discharging condenser QC, while in the counting-train, a relay AA is operated and relay A holds until slow release relay G drops out and returns the circuit to normal. If the fault persists, however, the breaker again trips immediately. Second trip.-Relay AP is again released firing tube CCT and operating relay P which now operates a relay B, relay A being released at contact p2. Relay CL again closes the breaker whereupon relay AP again releases relay P, releasing relay AA at contact p2. Relay B locks and a relay BB operates. Third trip.-Relay A operates in turn operating relay CL again. Relay AP operates and relay P releases and operates relay AA. Relays A, B, BB are now held. Fourth, trip.-Relays A, B are released at contact p2 whereupon relay CL again operates and relays AA, BB are released at contact p2. This locks relay AP over contacts g2, aa4, bb4, ap2. Fifth trip.- The locking circuit for.relay AP completed by the above sequence of operations, prevents relay AP from releasing and the breaker remains open with all the other relays released until it is closed by a local circuit, when relay G will release and the circuit will be reset. The charging time of condenser QC may be adjusted by a variable resistance YCC. The trips may alternatively be counted by a condenser-charging and cold cathode tube circuit.

Filed: 1975-01-22
Abstract: 1461367 Electronic watches SUWA SEIKOSHA KK 22 Jan 1975 [30 Jan 1974] 2819/75 Heading G3T In a watch having a digital time display, axial movements of an external crown are used both to select a part of the display to be corrected and to correct the selected part. As described the crown is biased to a middle position N from which it can be pulled out to position PL or pushed in to PS. Starting from the normal running condition 7 of the watch, a first pull and release of the crown changes the circuitry to condition 8 in which the seconds indication flickers and may be advanced in unit steps by successive depressions of the crown. A second pull and release produce condition 9 for similar minutes correction, and a third pull and release condition 10 for hours correction. A fourth pull produces condition 11 which is the normal condition like 7. Pushing or pulling of the crown causes a switch lever (12), Fig. 5 (not shown) to pivot, thus grounding one of two spaced contacts (13, 14). Logic circuity using AND gates (15-17), Fig. 6 (not shown) to select the desired part of the display is briefly described.
