IPC: B24D5/00
Abstract: 133,914. Sterling Telephone & Electric Co., and Harrison, C. May 13, 1919. Severing; wheels.-Vulcanite, ebonite, and like materials are divided or severed by means of a carborundum wheel running at high speed and provided with a water spray to keep the work cool and prevent dust. The wheel preferably is built up of alternate rings of carborundum b, d, q and of shellac or other non-abrading material c, p. All the rings are mounted on a sheet-metal disk a, which also forms the boss e of the wheel. The non-abrading rings are of a radial depth at least equal to the thickness of the work, so that the whole of the outside grinding-ring may pass through the work before the next abrading-ring comes into contact with it. When the outside ring is worn, the adjacent non-abrading ring and the corresponding portion of the disk a can be readily cut away, leaving the inner abrading-ring ready for use, and so on until all the abrading- rings have been consumed. Dished metal plates f, Fig. 2, of varying sizes, are used to strengthen the wheel. A construction of machine is described in which the wheel is mounted over a bed-plate provided with a work guide and feed support, which is preferably made capable of reciprocation both vertically and horizontally. A hood covers the wheel in order to minimize dust, The water-supply jet is inside the hood.

Title: Improvements relating to electrically-operated step-by-step driving mechanisms
IPC: G04C13/10
Filed: 1944-07-18
Abstract: 593,029. Electric clocks. DENTON, L. E. July 18, 1944, No. 13727. [Class 139] [Also in Group XXXV] A self-starting electrically-operated step-bystep driving mechanism used for example in driving the hands of a secondary clock, has a vibratory system energised by an electro-magnet which continually receives current impulses, the natural period of oscillation of the system being slightly different from the interval between successive impulses, and has means for controlling the amplitude of the swing. In Fig. 1, a pendulum 3 has an armature 2 and a balance weight 4 mounted on a thread for adjusting its natural frequency. An electromagnet 1, is mounted offset from the rest position of the pendulum (shown in full lines) so that the system will build up an oscillation when the impulses are applied. When the amplitude becomes too large, the armature 2 strikes the adjustable stop 5 so that the frequency of oscillation is increased and the phase relation of the pendulum is advanced with regard to the impulses whose effect on the armature is thus reduced. A cam 7 fixed to the pendulum, operates a lever 8 driving a ratchet wheel 10. In a modification, Fig. 4, the electromagnet has two poles 12 and an armature 2 (shown in its mid-position) oscillates on a vertical pivot and is controlled by a spiral balance spring. A stop 15 on the armature engages a fixed resilient stop 16 when it has swung through 180 degrees and causes a phase displacement as before, whilst the drive to the ratchet wheel is by a pinion 18 fixed to the armature actuating a toothed segment 19. Fig. 6 shows an alternative means of advancing the phase of the armature by means of a stop 32 acting on the balance spring 13 to reduce its effective length when excessive amplitude causes undue expansion of the spring. In this case the reverse arrangement may be used and the vibratory member may have a natural frequency above that of the impulses and the correcting influence may act to retard its phase position.

Abstract: 642,730. Condenser arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. May 22, 1947, No. 13779. Convention date, May 23, 1946. [Class 38 (iv)] [Also in Group XL (c)] A circuit for rapidly transmitting to output terminals 7, 8 voltage changes in one direction at input terminals 9, 10, whilst delaying the transmission of input voltage changes of the reverse direction, comprises series-connected condensers 14, 15 shunted by resistors 16, 17 across the output terminals, and charged through a rectifier 11, a further charging path for condenser 15 being provided through another rectifier 12 and a resistor 13. The capacity of 14 is smaller than that of 15 and the time constant 12, 13, 15 is made equal to time constant 14, 16. Application of a negative voltage step A, Fig. 2, to the input terminals, causes the voltages across condensers 14, 15 to vary as shown in curves Band C, respectively, resulting in an output voltage curve D. Removal, or reduction, of the input step voltage cuts off the rectifiers and the output voltage falls at a rate determined by the time constant of 15, 17, condenser 14 already being discharged. More than two resistance-shunted condensers, together with further rectifiers, may be included in the series, the capacities of the condensers tapering along the series and the charging time constant of any condenser being equal to the discharge time constant of the adjacent condenser of smaller capacity. Specification 642,731, [Group XL (c)], is referred to.

Title: Exhaust-driven turbo-supercharger and internal combustion engine
IPC: F02B33/44
Filed: 1977-04-01
Abstract: The exhaust turbocharger comprises an exhaust turbine and a supercharging blower which is driven by this and has a connecting line (16) between the intake line (3) and the pressure line (5). A blow-off valve (17), actuated as a function of the intake pipe vacuum of the internal combustion engine (8), is arranged in the connecting line. By bypassing the impeller a fall in the speed of the latter at low engine output, for example in overrun conditions of a motor vehicle, can be avoided so that a rapid engine response is obtained upon accelerating. The blow-off valve (17) and the line (16) are arranged in the housing (19) of the supercharging blower. It is thereby possible to design the exhaust turbocharger with the blow-off valve so that it is especially compact and easy to assemble. <IMAGE>
