Patent GB-1348973-A (GB)
Title: Synchronized time delay circuits
IPC: H03K17/28
Filed: 1973-02-07
Abstract: 1348973 Synchronized time delay HEWLETT-PACKARD CO 7 Feb 1973 [20 April 1972] 5949/73 Heading H3T Synchronization of a time delay using a Schmitt trigger 8 with a rising input voltage at the base of transistor 10 is effected by applying synchronizing pulses to the output at the collector of transistor 12, which normally conducts to pass the synchronizing pulses to the emitter of 10. When the input voltage is sufficiently positive a negative going excursion of the synchronizing pulse waveform causes 10 to conduct and cuts off 12 so that further synchronizing pulses do not disturb the circuit. The rising input voltage is produced by operating switch 22 to charge capacitor 26 over resistor 24.

Title: Improvements in or relating to the manufacture of unstainable irons and steels
IPC: C21C7/00
Filed: 1922-03-01
Abstract: 198,423. Wild, R., and Wild, A. H. March 1, 1922. Alloys.-In a process for the production of ferroalloys, particularly iron-chromium alloys, such as ferro-chrome or unstainable iron or steel, of the type in which compounds of one or more of the metals are reduced by means of silicon, the reduction is effected in presence of an excess of the reducible compounds over the quantity chemically equivalent to the reducing-agent. The reducing- agent may be ferro-silicon, and the reduction may be effected in the presence of lime or other slag-forming material. A charge of chromite may be first fused with a bath of iron or steel and the silicon reducing-agent added, whereafter a further charge of chromite substantially equivalent to the reducing-agent is added; or the chromite and reducing-agent may be heated together and iron or steel afterwards added: or a ferro-chrome may be first prepared using excess of chromite as described above and the fused product may be mixed with molten iron or steel preferably containing dissolved oxygen or oxides. A small proportion of a deoxidizing agent such as ferro-manganese, silico-manganese, ferro-silicon, or aluminium, may be added to the bath prior to the addition of the silicon reducing-agent. The material may be submitted to an oxidizing blow at any convenient stage, preferably in presence of an element such as manganese which is more readily oxidizable than chromium, as described in Specification 197,733. In some cases part or all of the excess of reducible compound may be provided by another compound such as iron oxide. Specification 174,618 is referred to.

Title: Improvements in Mechanism for Feeding Tapered Rollers or similar Articles.
Inventor: JUSTICE PHILIP MIDDLETON
IPC: B65G47/14
Filed: 1916-05-03
Abstract: 105,963. Justice, P. M., (Timken Roller Boaring Co.). May 3, 1916 Feeding tapered rollers &c.-Consists of means for feeding tapered rollers, for bearings, and like articles to gauging-machines &c., and comprises a device for arranging the rollers end to end, and a turning- device which receives the rollers from the first device and turns them so that similar ends all point in the direction; the turning-device comprising means for frictionally gripping a roller at its largest diameter and means for turning the roller about that point as a pivot. The apparatus may form an attachment to a gauging-machine. The container 4 is substantially V-shaped in vertical cross-section both transversely and longitudinally; it is fed from a hopper 5 provided with an sdjustable gate 6 fitted with a hinged spring-controlled flap 9. A vertically reciprocating stirrer 25 and an oscillating feeding-blade 29 work through the bottom of the container. The thickness of the blade corresponds with the diameter of the rollers, and in its upper edge is a groove which forms a seat; as it moves upward through the mass in the container, it carries up a number nf the rollers, some of which lie lengthways, others transversely &c. In the top position, there is a dwell in the movement and the rollers slide down the blade into the passage 36, the mouth of which is arranged to prevent the passage of rollers disposed otherwise than longitudinally. From the passage 36 the rollers descend along a closed shoot 37 to the table 41 of the position-rectifying device, which is just wide enough to receive one roller; the lowest roller in the shoot moves on to the table by gravity and holds up the column in the shoot. Working over the table, in a direction at right-angles to that of the shoot 37, are three pivoted fingers 50 which are moved inwards by cams against the action of springs. For the first part of their movement, the fingers advance together and push the roller over the table and under a spring-pressed pivoted friction-blade 42; the under surface of this blade makes contact with the roller at its largest end only so that, when the central finger bearing upon the middle of the roller is advanced alone, the roller is turned about its large end as a pivot and assumes a position at right-angles to its original position on the table and with its small end leading, whether the small end was to the right or to the left hand side of the table. The two side fingers are now advanced together and one or the other, according to the way in which the roller was turned, strikes the end of the roller and pushes it endways clear of the friction-blade into the inclined shoot 40. This shoot is formed with two converging channels, the upper ends of which correspond to the two positions in which the rollers may be advanced.

The movements of a pressure-responsive element 21, Fig. 1, in a fluid-tight casing 10 are transmitted to an element outside the casing 10 by a U-shaped lever 17, the lever 17 being secured in a fluid-tight manner to a flexible wall 16 of the casing and being otherwise unsupported. The whole is so arranged that the lever 17 engages the element to be moved at a point which, throughout the limits of movement of the various parts, remains close to a line which extends through the point of engagement of the transmitting member 17 with the pressureresponsive element 21 and parallel to the movement of that member. In Fig. 2, the limb 18 of the U-shaped member 17 is telescopic and is pivotally connected to the centre of the pressure responsive element 21.

Either handle can be locked to the sleeve by a bolt 24, Fig. 9, adapted to be pressed against a spring into engagement with a hole in the bolt-sleeve. The handles are normally held in their forward position by the inclined forward edges of hinged plates 22 which cover the longitudinal slots in the casing. The plates are raised when the charging handles are drawn back.

Abstract: 1,149,836. Chloramine. W. R. GRACE & CO. 9 Feb., 1968 [26 April, 1967], No. 6591/68. Heading C1A. Chloramine is produced continuously by reacting, in the gaseous phase, one molar proportion of chlorine with at least 1À9 molar proportions of ammonia in the presence of at least 1 molar proportion of an inert gas, at at least 250‹ C. The molar proportion NH 3  : Cl 2  may be from 2 to 15, and the temperature may be from 275‹ to 700‹ C. The diluent gas is commonly nitrogen, but may also be argon, neon, carbon dioxide, helium or krypton, and the chloramine produced may be absorbed in a solvent, e.g. diethyl ether, toluene, benzene, chlorobenzene. A preferred embodiment includes maintaining the reaction products in the range 50‹ C. to 250‹ C. while ammonium chloride by-product is removed. The reaction may be carried out in an apparatus as shown in the figure. Chlorine is passed down a tube inside an adjustable sleeve, which may be heated, into a chamber containing a mixture of ammonia and the inert gas. This chamber is heated. The products are withdrawn through a plug of glass wool, which retains the ammonium chloride, and allows the product chloramine gas to pass through.
