Inventor: ZOELLY HEINRICH
IPC: F16H57/02
Filed: 1917-07-25
Abstract: 108,320. Zoelly, H. July 26, 1916, [Convention date]. Toothed gearing.-The radial component of the pressure between the teeth of spur gearing, tending to force the wheels apart, is balanced by magnetic means. A cylinder 11 on the shaft of a driving-pinion 4, Fig. 2, is pulled downwards by ar. electro-magnet placed vertically below it on a standard 12, to neutralize the vertical component Z, Fig. 1, of the pressure N between the teeth. By displacing the magnet to one side, the pull M' can be directly opposed to the normal pressure N. Similar cylinders can be placed on both sides of the pinion 4 and also on the shaft of the driven wheel 5. To prevent the wheels 4, 5 from being drawn too closely together, cylinders 17, 18 in rolling contact are placed on the two shafts. The functions of the cylinders 11, 17, 18 may be combined by providing two cylinders 21, 22, the contacting surfaces of which are magnetized by an electro-magnet 23 having poles projecting into the converging spaces between the cylinders. As shown in Fig. 7, the toothed wheels may themselves be magnetized by windings 31 so as to attract one another. The shaft bearings 41 are supported above and below by springs.

Title: Improvements in or relating to processes and moulds for the centrifugal casting of pipes and other pieces
IPC: B22D13/02
Filed: 1953-04-21
Abstract: 725,601. Centrifugal casting machines. SOC. METALLURGIQUE ARIEGEOISE ET LORRAINE. April 21, 1953 [April 21, 1952], No. 10895/53. Class 83 (1). A process of centrifugally casting tubular metal pieces in which the molten metal is given a rotational movement equal to that of the horizontal, core-less mould 1 before its introduction therein, consists in that the poured metal is cooled in an enclosed atmosphere so that cooling occurs only from the outside towards the inside of the piece. The mould is rotated by a motor 5a through rollers 4 and is set at an angle of 4 degrees. It has a lining of sand 2 and is closed at one end by a cap 7 adjustable by a screw 17 in an end-plate 14. The cap 7 has gas passages 13 and the endplate 14 has one-way ballvalves 19. A metal distributer having a clay lining 21 and a silico-clay entry ring 22 is attached to the front of the mould, with a screen E interposed. The screen comprises members 23, 26 held together by an alloy key 27, Figs. 3 and 4, and sand facings 29 having orifices 28a. Metal is poured initially at a high rate to fill the distributer 20 which is formed with recesses 32 to direct the metal to the orifices 28a. The orifices are thus submerged and gases escape through the valves 19. The pouring-rate is then lowered to maintain the level in the distributer. Thus no cooling air can enter the mould. During cooling and subsequent shrinkage the cap 7 is advanced by the screw 17, the sand 12 being thus sheared through. The compressive end-force on the piece assists in preventing. cracks. The alloy key 27 having melted, the member 26 of the screen E is free to move inwardly as the piece shrinks. When cooling is complete, the distributer is removed and the dead-head is cut off, at the portions formed by the recesses 28, by a welding torch. The recesses 28 may be inclined to accelerate or decelerate the metal. In a modification, the distributer has an entry 42, Fig. 7 passages 44 leading into an annular passage 45 and further passages 46 leading into the screen. In a further modification the metal enters the mould past a conical screen 48, Fig. 8, supported by three arms 50. Gases escape through pipes 56 thus enabling the opposite end of the mould to be completely sealed. In a still further modification, gases may be withdrawn by pipes 58, Fig. 10, behind the cap 7, resulting in a partial vacuum which assists de-gassing. In a final modification, an inert gas is supplied through an internal passage 66, Fig. 11, in a stopper 64 and through a sleeve 67 surrounding the opening 63 of the distributer. The moulds may have asbestos, paper, or cooled metal linings.

Abstract: 1476704 Timed alarms NISSAN MOTOR CO Ltd 17 March 1975 [16 April 1974] 11066/75 Heading G3T An arrangement for warning a vehicle driver when his alertness falls below a certain level, comprises sensors for sensing his alertness and a timer circuit which activates a warning device, e.g. a buzzer, if it is not reset by a signal from a sensor indicating a driver activity within an adjustable time period. The timer includes an integrator, 6, Fig. 1, which produces a linearly increasing voltage commencing when the ignition switch is turned ON. If the integrated voltage reaches a predetermined level, set by a standard voltage source 10 and indicating a minimum level of alertness, before a signal appears from a sensor 18 or 20, a comparator 8 activates a warning device 16. If a sensor produces an output, a pulse generator 26 including an OR gate resets the integrator 16 and causes integration to start again. The sensor 18 may detect the frequency of the driver's manipulation of switches such as direction indicator, radio &c. while the sensor 20 detects the frequency of manipulation of clutch, brake, steering wheel &c. Each sensor produces an output when a respective value is exceeded indicating an alert driver. In a standard voltage generator detailled in Fig. 3 (not shown) a sensor (58) senses abnormal driving conditions and modifies the standard voltage level accordingly. The constant voltage from a generator 2, which is integrated to provide a timing function, may be changed in response to vehicle speed, a quicker response being required from the driver the faster the speed. The integrator is detailled in Fig. 2 (not shown) and includes an operational amplifier with a capacitor feedback path which is shunted by a relay switch when a sensor produces a signal.
