Title: Improvements relating to four-stroke-cycle internal-combustion engines
IPC: F02B75/04
Filed: 1931-04-27
Abstract: 372,544. Driving gear ; reversing. BONFA, A., 608, Umbilo Road, Durban, South Africa. April 27, 1931, No. 12447. [Classes 7 (ii) and 7 (v).] In four-stroke cycle engines wherein the piston drives the power shaft through gearing as described in Specification 346,592 the crank pin path describing a major hypotrochoidal curve due to rolling of pinions inside stationary internally-toothed wheels, the wheels 8, 9 are made adjustable by means of worm gear in order that the engine may be reversed ; by this means the clearance at the end 'of the exhaust stroke is made less than that at the end of the compression stroke for each direction of running. Two sets of cams-only one of which is shown -are formed on a sleeve 44 feather-keyed on a drum 11 on the main shaft; stops 43 limit the axial movement of the sleeve on the drum. The sleeve is held in one or other of its positions by a stirrup 54 held by a leaf spring 52 on the control rod 50. One or other of the spring- pressed catches 57, 58 enters a recess in the crank case to hold the stirrup, the catch being 'released by a spring-pressed lever 65 as the main shaft and drum reverse. In a modification the sleeve is made in two parts one carrying the inlet cams and the other the exhaust ; these two parts are adjustable angularly on the drum 11, their movement being limited by stops. According to the direction of rotation the two parts adjust themselves about the drum; the angular movements of the two parts are unequal.

Filed: 1956-04-24
Abstract: 803,468. Winding toroidal coils. ONISKO, J., and WATSON, J. R. April 24, 1956 [April 25, 1955], No. 12488/56. Class 83 (4). Core-winding means including a bobbin adapted to be rotated around a core passing therethrough has means to direct any loose filament back into the bobbin and/or means to prevent loose filament from being thrown laterally over one edge of the bobbin. A bobbin 32, linked with a toroidal core 54 on a slotted table 67, is supported and driven by two driving wheels 29 and a spring-urged idler wheel 33. A plate 44, supported on an arm 43 movable about a vertical pivot 42, has an annular groove 46 in which is disposed an arcuate rubber pad 47 with a metal facing 48 bearing against one side 92 of the bobbin 32. The pad 47 extends from a notch 53 in the plate 44, accommodating the core 54, counter-clockwise to a five-o'clock position and is urged by adjustable segments 49 so that pressure on the bobbin increases from the five-o'clock to a nine-o'clock position and is again light to the notch 53. In operation, with the bobbin rotating in the same direction as for winding on, wire 74 is paid out from a peripheral cavity 73 of the bobbin over its edge 76 and over an edge 75 of the plaet 44 to form a Z-kink 77 which helps to lock the wire against the inside of the bobbin particularly when it passes the end of the pad 47 at the notch 53. To prevent a loop 74c, Fig. 9, from being thrown outwardly from the bobbin just after the Z-kink 77 passes through the core 54 and before the slack is taken up, a leaf spring 78 is adjustably mounted on the plate 44, at the end of the pad 47, to bear on the edge of the side 92 of the bobbin, Fig. 12. To prevent the loop 47c from being thrown over the side 91 of the bobbin a plurality of resilient plates 87 are mounted on a guide plate 61 to bear lightly against the edge of the side 91. Instead of the leaf spring 78 a spring-urged plunger 78a, Fig. 13, may be used and, instead of the plates 87, a tube 87a, Fig. 15, with jet holes 97 through which air under pressure is passed to deflect the loop 47c to the bobbin. Reference has been directed by the Comptroller to Specification 738,125.

Title: A new or improved method of producing high secondary electron emission from electrical conductors
IPC: H01J9/12
Filed: 1940-08-16
Abstract: 543,201. Electrode materials. INTERNATIONAL TELEVISION CORPORATION, Ltd., NAGY, P., and GODDARD, M. J. Aug. 16, 1940, No. 13080. [Class 39 (i) j ] Electro-positive metals such as beryllium are subjected, after degassing, to bombardment by a stream of electrons of high current intensity for the purpose of increasing the secondary electron emission coefficient several times greater than unity. The treatment may be applied to the restoration of the secondary emission properties after they have decreased during normal operation of the device in which electrodes so made are used. In this case the various electrodes are connected to suitable sources of potential so that the stream of electrons is directed to the electrode under treatment and so that such electrode is maintained at a potential more positive than any other electrode in the device to prevent positive ions from reaching it.

Title: Improvements in or relating to straight bar rib knitting machines
IPC: D04B11/00
Filed: 1957-04-26
Abstract: 892,977. Knitting. TAYLOR, G. July 18, 1958 [April 26, 1957], No. 13304/57. Class 74 (2). Selected needles 4 of one bed of a straight-bar rib knitting-machine are mounted in a bar 5 for operation independently of the remaining needles of the bed, a loop transfer device 4a is mounted for operation in association with each selected needle and means is provided to displace the mounting of the selected needles and loop transfer devices at required times to transfer loops from the selected needles to next adjacent ones of needles 1 of the other bed automatically. The devices 4a may, as shown, be loop spreaders on machine needles 4 which are longer than the remaining machine needles 2. The bar 5 can be moved, to project the needles 4, through rollers 6 running in cam slots 7a in a plate 7 slidable in a relatively stationary support 8 and movable by a slidable cam 10 operated by patterning or disc cam mechanism 11. Rib welts are started on a greater number of needles than is necessary for running on to a point bar and are so knitted, with the machine needles 2 and 4 operating in unison, until just before the production of a slack course C, or courses. The needles 4 are then projected independently and to a greater extent than the needles 2, to spread their loops. All the frame needles 1 are now raised for the next course, the said next adjacent needles thereof penetrating the spread loops. The frame needles then receive yarn for the said next course C, drawing it over the needles 2 and 4 and through the old loops and the spread loops which are surrendered to them. Thus double loops DL are produced on spaced frame needles and the number of wales is reduced to that required. The needles 4 remain projected, and thus inactive, during knitting with the machine needles for that course and during one or more of following waste courses.
