Title: Improvements in or relating to two-stroke cycle internal combustion engines
IPC: F02B37/04
Filed: 1963-01-15
Abstract: 972,038. Charging two-stroke engine cylinders. GOTAVERKEN A.B. Jan. 15, 1963 [Jan. 18, 1962], No.1835/63. Heading FIB. The delivery pipe 13 of a main exhaust driven turbocharger 8, working in parallel with an auxiliary independently driven compressor 6, is connected through a valve 17 to branch ducts 18, 19, leading respectively to atmosphere and the turbine inlet pipe 10. At starting a by-pass valve 11 is set to render the turbine 7 inoperative and all the charge is supplied by the compressor 6. When the engine has passed the starting speed, valve 11 is set to supply exhaust to turbine 7 and valve 17 connects pipe 13 to atmosphere through pipe 18 whereby the turbine can rapidly accelerate the compressor 8. When the turbo set reaches a predetermined speed, valve 17 is moved to connect pipe 13 to pipe 19 whereby the air delivered by compressor 8 supplements the exhaust gases and facilitates acceleration of the turbo set. Finally, when the turbo set reaches a predetermined speed, valve 17 disconnects the ducts 18, 19, from pipe 13 and the compressor 8 delivers to the engine through intercooler 14 and non-return valve 21, the compressor 6 being rendered inoperative manually or automatically when the delivery pressure of compressor 8 exceeds a predetermined value. The valve 17 may be controlled automatically from engine fuel control member.

Title: Improvements in or relating to electric signal transferring and/or storing systems comprising multi-legged magnetic cores
IPC: G11C19/06
Filed: 1958-01-21
Abstract: 859,476. Circuits employing bi-stable magnetic elements; controlled non-linear inductors. GENERAL ELECTRIC CO. Jan. 21, 1958 [Jan. 22, 1957], No. 2010/58. Class 40 (9). [Also in Groups XIX and XXXV] A magnetic core device comprises a closed core having a first aperture dividing the core to provide first and second parallel flux paths a, b and a second aperture dividing the core to provide third and fourth parallel paths c and d, a biasing means such as a winding 105 or a magnet providing counter-clockwise flux in the path a, a clearing winding such as winding 125 to set flux in the same (i.e. counter-clockwise) direction and a signal winding to reverse this flux. The core may be wholly of a ferrite material having a square hysteresis loop or may include a part 103 of soft ferrite. In operation as a digital storage element a binary " 1 " is represented by a positive pulse on winding 111 and a binary " 0 " by absence of a pulse giving rise to flux 109 for a stored " 0 " and flux 110 for a stored "1," so that a clearing pulse on 125 will produce an output on winding 130 if a binary 1 has been stored. This clearing pulse gives a destructive read-out. For non-destructive read-out an A.C. signal winding 115 and an output winding 119 linking the second aperture are provided. When flux in the second leg is in direction 109 the whole core is saturated by a circuital anticlockwise flux and no coupling exists between windings 115 and 119. When the flux is in the direction 110 it is localized around the first aperture and no set flux exists in the lower half of the core, i.e. no flux exists in the fourth path, so that coupling exists between the winding. Hence an output on winding 119 following a sensing signal on 115 indicates a stored " 1." Magnetic arrays.-In an array, Fig. 2, each input winding is duplicated into x and y windings 201, 202 and are connected in rows and columns, half-currents in the windings being individually insufficient to switch the flux but sufficient when occurring coincidentally. As shown, the clearing winding 205 links the complete core cross-section. Shift register.-The device may be utilized in a shift register (Fig. 3, not shown). If a pulse on winding 111 has set flux in direction 110, when a clearing pulse is applied to winding 125 an output pulse occurs in winding 130 which pulse is applied through a delay line to the next element in the register. Logical device.-A pair of devices may be combined to perform logical functions as shown in Fig. 4. Signal sources 405, 408 each feed a winding on cores 401, 402, the fluxes so produced being opposed in 401 and additive in 402. An output in device 424 is obtained whenever either 405 or 408 are pulsed (OR function). 420 receives a signal only when 405 is pulsed alone.

Heading G2A A slide holder having automatically centring slide-engaging means actuated by urging a slide against a movable stop and being guided for movement transversely of the direction of insertion of the slide is characterised in that the slide-engaging means have V-shaped engaging surfaces. As shown, 1 is the mounting plate of a slide holder for an optical projection apparatus such as a printer, and which can be introduced on to the negative stage of such apparatus. Two raised ledges 1c support the framed slide 3 as it is inserted in the direction of arrow 4 until it is located over the picture window 2. Mounted on pivots 5 adjacent the top corners of the window are two bell crank levers 6. The two arms of each lever terminate in lugs 7, 8 respectively, the lugs having V-shaped engaging notches (Fig. 2, not shown). The lugs 7 have projecting pins 11 which enter the ends of a compression spring 12 connecting the two levers, and holding them in the rest position of Fig. 1. The axes of pins 11 intersect the pivot points 5, and form an angle α with the line c directly joining these points. As the slide 3 is pushed into the holder, guided by the edges 15 of guide plates 13, its leading edge engages the V-notches 9, and is centred thereby in the projection plane. Further movement of the slide causes the levers to pivot, and after the point of maximum compression of the spring has been passed, the spring action causes the levers to pivot further, until the V-notches 10 in lugs 8 are brought into engagement with the sides of the slide, thus also serving to centre the slide in the projection plane as well as holding it firmly. To release the slide, it is necessary only to push the lugs 7 back in the direction opposite to arrow 4.
