Title: Improvements in or relating to counters or registers
Filed: 1934-10-24
Abstract: 446,179. Motors. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. Oct. 24, '1934, No. 30540. Convention date, Oct. 25, 1933. [Class 35] [See also Group XIX] Synchronous electric motors each having an unwound rotor which constitutes a denominational registering element, are combined to form a counter of the kind into which the digits of an amount can be entered simultaneously and are operated by a continuously operable source of current pulses. The operating impulses for a motor may be generated by an electric commutator, and selected for transmission to magnets controlling selected relays by a plurality of key controlled contacts connected between the commutator and the magnets, or alternatively the operating impulses may be generated and selectively transmitted to the relays by perforations in a record which is fed past brushes connected to magnets controlling the relays. Each of the operating impulses corresponds to a digit to be entered, and the interval between it and a fixed moment in the cycle is such that the number of pulses emitted from the currentsource during the interval is proportional to, for example is twice, the value of the digit. The counters comprise a plurality of denominational units, each unit comprising a synchronous electric motor mounted upon a separate supporting plate 75, Fig. 3, supporting pairs of electromagnets 76 and 77, each pair constituting with the plate 75 a horse-shoe magnet having two pairs of poles 78. The polepieces 78 are arranged circumferentially about a shaft 79, Fig. 6, secured to which is a toothed rotor 80 with ten teeth 81. The arrangement is such that when two diametrically opposed pairs of teeth 81 register with two pairs of poles of one pair of magnets, the two pairs of poles of the other pair of magnets will register with the gaps between pairs of the teeth. If the pairs of magnets 76 and 77 are energized alternately by current pulses, the rotor 80 will rotate in synchronism with the current pulses at a rate proportional to the frequency of the pulses, to an extent proportional to the number of pulses transmitted. The number of current pulses is twice the digit to be entered. A device for preventing retrograde movement of the rotor 80 comprises three spring-controlled balls 84, Figs. 5 and 9, disposed between a groove in the shaft 79 and cam surfaces 85 in a bearing block 83. The magnets 77 are normally energized by a direct current and tend to hold the rotor 80 in the position shown in Fig. 6.

Abstract: 1466046 Chucks; hollow spindles P FORKARDT 23 July 1975 [29 July 1974] 30734/75 Headings B3B and B3T A power operated chuck comprises jaws 2 movable radially in guides in a body 1 by axial movement of a plunger 5 having inclined grooves receiving inclined guides 4 on the jaws, and is characterized by the plunger being movable axially out of the normal working range of its movement to actuate the jaws into a retracted position in which the plunger 5 becomes disengaged from the jaws, and wherein in its retracted position the plunger is locked against rotation relative to the body, and each jaw is radially located to ensure re-engagement of the plunger by a spring loaded bolt 18 engaging a recess in the jaw. Additionally spring plungers 19 each having a head 19a engageable in a radial groove 2b in a respective jaw during normal engagement of the plunger with the jaws, ensures that even after a fracture of the guide portion 4, a jaw will not flyout during rotation of the chuck. This additional plunger 19 is withdrawn from its groove 2b on retraction of the plunger by the plunger engaging a member 20. An extension 20a of the member 20 enters a groove of the plunger to prevent its rotation in the body. The plunger is actuated, via a rod 11, by an air or hydraulic piston 9b or alternatively by an electric actuator. Switches (16) (Fig. 1, not shown) and 17 operated by cams (14), 15 ensure operating control during normal working movement zone A and retracted zone Z. The spindle is prevented from rotating during the retracted zone Z period of operation. In an alternative embodiment (Fig. 3, not shown) the plunger is power operated only over its normal working zone A, and is retracted to disengage from the jaws by using a key (21) to manually retract the plunger. The key (21) is locked into the plunger to prevent its removal until re-engagement is established. The function of the separate plungers 18, 19 are combined in this embodiment, the plunger being manually released from the jaw groove 2b by, e.g. using a screw driver (26).

IPC: F02C7/08
Filed: 1949-12-05
Abstract: 693,616. Thermal regenerators and recuperators. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 1, 1951 [Dec. 5, 1949], No. 31205/49. Class 64 (i) [Also in Group XXVI] To enable a fuel of low calorific value, such as a gaseous mixture of coal dust dispersed in air or methane in mine ventilating air, or solid fuel, e.g. peat saturated with water or sewage sludge, to be used in a gas turbine plant, the combustible gas mixture or combustion air is heated in a regenerative type heat-exchanger before its entry into the combustion chamber by the combustion gases prior to their entry into the turbine. In the arrangement shown, the compressor 1 feeds air to a gas turbine 3 through a heat-exchanger 2 heated by the turbine exhaust gases and a further regenerative heat-exchanger 5. The heat-exchanger 5 is arranged to add sufficient heat to the air for combustion when using solid fuel and to the fuel-air mixture when using a gaseous fuel so that the combustion is self sustaining. This heat-exchanger comprises two parts 7 and 9 with a combustion chamber midway at 8 and changeover valve gear 6. The arrangement is such that, at one stage, the incoming air-fuel mixture passes through part 7, which has been previously heated, to the combustion chamber 8 where it is burnt and then passes through the part 9 to the turbine 3. When the temperature of the part 7 has fallen sufficiently, the valve gear 6 is operated so that the air-fuel mixture passes through in the reverse direction, i.e. through the part 9 to the combustion chamber 8 and from this chamber through the part 7 to the turbine 3. When the temperature of the part 9 falls sufficiently, the valve gear 6 is again operated and the cycle repeated. Auxiliary fuel may be supplied through conduit 5a and valve 5b for starting purposes. The plant may be used to bum a solid fuel such as peat. In this case, the peat is comminuted and shredded and fed to the combustion chamber 8 and only the combustion air is preheated in the heat-exchanger 5. To avoid blocking the outlet side of the hea-texchanger with ash, a cyclone separator may be arranged at the outlet of the combustion chamber. If there is no risk of the ash impairing the efficiency of the heat-exchanger, the cyclone separator may be arranged at the outlet of the heat-exchanger to avoid damage to the turbine blades. An auxiliary heater may be arranged between the heat exchanger 5 and the turbine inlet to correct any temperature fluctuations. The regenerative heat-exchanger described may be replaced by one of the rotary matrix type. The matrix of the regenerative heat-exchangers may be constructed at least partly of combustion-promoting catalysts. This enables the size of the heat-exchanger 5 to be reduced. A further auxiliary combustion chamber may be arranged between the conduits 12 and 15 to bum an auxiliary fuel which may be of higher calorific value. According to the Provisional Specification, a recuperative heat-exchanger may be used.
