Title: Four stroke internal combustion engine
IPC: F02B23/08
Filed: 1974-10-14
Abstract: 1491231 Exhaust gas recirculation in IC engines YAMAHA HATSUDOKI KK 14 Oct 1974 [26 June 1974 12 Aug 1974] 44378/74 Heading F1B A multi-cylinder four-stroke I.C. engine has an inlet duct and valve controlled inlet and exhaust ports for each cylinder, means for introducing a fuel/air mixture into the inlet ducts and spark ignition means, the inlet ducts being interconnected with the exhaust pipe of the engine via a valve which controls the flow of exhaust gases towards the inlet ducts, means being provided for restricting the flow of gases by way of the interconnecting pipe between the inlet ducts in response to short pressure peaks in the inlet ducts. In an engine in which a separate carburetter is provided to feed each cylinder, exhaust gas is drawn from a thermo-reactor 40 and recirculated to the inlet pipe through a cooler 45 and through two vacuumcontrolled valves 46 and V 1  in series. The diaphragm 46a of valve 46 is subject to the vacuum immediately downstream of the throttle valve in one of the intake ducts 12b, so that valve member 46b is moved toward the open position when sufficient depression exists in the intake duct. Diaphragm 202 of valve V is pulled downwards by the depression in duct 12b against compression spring 201 to move valve member 200 to reduce or prevent flow of exhaust gas through each of the ports 207 to individual cylinders. Since recirculation pipes 13...d are inter-connected by valve ports 207, the low-pressure in a combustion chamber of which the piston is on the intake stroke may adversely affect the pressure at the intake port of another combustion chamber. To prevent this isolation means are provided in each of the recirculation pipes e.g. reed valves which open to allow flow of exhaust gas and close when a depression exists in valve V. Alternatively the isolation means comprises restrictions in the bore of the pipes 13a ...d, which restrict gas flow in response to short pressure peaks, but permit long-term pressure changes. The Specification also discloses that the intake pipes, adjacent the intake ports, are excluded from the effect of the liquid coolant circuit C of the engine and are cooled only by air, so that their temperature is 90‹C to 135‹C, preferably 110‹C so that if a film of fuel forms on the pipe wall it is vapourized. The crank-case interior and/or the fuel tank may be vented by providing a connection to the exhaust gas recirculation pipe.

Abstract: 915,876. Binaural transducers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 31, 1959 [Jan. 2, 1959], No. 44409/59. Class 40 (4). A transducing device for cutting or playing back twin channel gramophone records comprises a stylus holder 7 coupled by a first coupling arm to a first transducing element 3 and by a second coupling arm to a second transducing element 4, each of said arms comprising two parts connected in tandem and of which the modulus of rigidity of one part 2a differs from that of the other part 2b. For stereophonic applications the two arms have identical properties. In other applications, e.g. for recording or playing back a monaural signal and an echo signal, the two arms may have different properties. The modulus of rigidity of part 2a is less than that of part 2b. Part 2a may be of rubber or synthetic material (e.g. polyvinyl chloride containing 40% softener) while part 2b is of metal or synthetic material such as polyvinyl chloride containing no softener. The transducing elements 3, 4 are permanent magnets and each is journalled to be rotatable about its axis and is situated in a magnetic circuit 5, 6. Specification 394,325 is referred to.

Abstract: 1411951 Discharging hoppers K J HURST and W G PEARSON 28 Sept 1972 [8 Oct 1971 10 Sept 1972] 44925/72 Heading B8S [Also in Division A4] Dispensing apparatus, e.g. for pills or capsules comprises a support 24 having an inclined support surface, a disc 30 having rotary drive means on the support 24, an upstanding wall 27 on the disc 30 defining a rotary hopper 26, and slots 34 in the disc 30, communicating at one end 41 with the hopper 26 and passing over a drop-out aperture 46 in the support surface as the disc 30 rotates so that pills &c., pass through the slots 34 to the aperture 46 and are discharged in succession. The slots comprise an intermediate section angled in the direction of disc rotation, Fig. 2. As the disc 30 rotates, the pills, &c., move towards its centre in the slots, to a discharge point monitored by a counting sensor. The hopper 27 is secured to the periphery of the disc 36 for rotation by a motor 45 on the sloping support 24, the whole forming a unit which may be housed with others in a cabinet for dispensing several kinds of pills &c. All units may be connected to a single counting control means 18. The disc has a truncated conical upper surface 36 cut away adjacent the periphery to expose the slots to a contained mass of articles. In one form, each slot has a third section 38 joined to second and first sections 39, 41, the section 38 having a trailing angle to obviate jamming of articles entering. The leading angle of the section 39 causes articles other than that which has reached the innermost section 41 to fall back as the respective slot approaches the discharge aperture 46 in the surface 24. The sensor arm 53 is accommodated in an annular slot 44 in the disc base, which intersects the section 41 and sends a signal to a counting circuit, Figs. 7, 8 (not shown), which may be substantially as described in U.S.A. Specification 3,368,713 and includes means to stop the disc rotation when the desired count is reached. The control system may include means to permit a number of dispensing units to be operated together and to give a visual count and an indication of the number of dispensing operations, Fig. 8 (not shown). In another form of disc, for pills, Fig. 6 (not shown), the leading face of the section 38 may have a depression (47) to trap the pill adjacent that being dispensed to prevent it touching the sensor arm and giving a false count. In a further form for capsules, the inner section may be curved in the direction of rotation, Fig. 16 (not shown), followed by a reversed curved portion and a straight portion leading to the disc periphery. The discs may be interchangeable for different sizes of article, a complete set being provided to enable one dispenser to be used for the complete range of pills and capsules. The base 24a on which the disc rotates may be spring biased towards it to obviate jamming of articles between the base and disc 32a, Fig. 11.
