Abstract: 722,721. Creasing and printing machines; feeding sheets. JONES (TWINLOCK), Ltd., P. Dec. 31, 1952 [Jan. 15, 1952],No. 1167/52. Classes 100 (1) and 100 (2). A machine for creasing card material comprises at least two successively arranged groups of creasing rollers adapted to form a series of substantially parallel creases in the card material, the first group being adapted to form one crease only and subsequent groups forming two additional creases straddling the creases previously formed. A pair of creases may be formed simultaneously on either side of a previously formed crease, without danger of tearing the card, because of the "give" in the central crease. The machine illustrated in Fig. 1 is adapted to make five creases and comprises a feeding section A, a creasing section B and a printing section C. The creasing section comprises three groups of rollers 10, 11, 12 operating in pairs, one 14 of each pair presenting a groove 14<SP>1</SP> and the other a rib. A single crease made by the first pair of rollers 10 becomes the third of the five and is straddled by the creases made by the second group of rollers 11 which are the second and fifth creases. The second and third creases are straddled by the first and fourth creases made by the roller group 12. All the creasing rollers are synchronously driven by gears 24. Feeding sheets.-Cards are fed to the creasing rollers by a felt blanket 1, Fig. 3, passing over an idler roller 2 and a driven roller 3. The cards are held in contact with the blanket by belts 4 passing over idler pulleys 5 and driven pulleys 6. The cards are registered for the printing process before passing through the creasing section by a gate comprising a number of arms 9 mounted on a shaft 8 rocked by a cam 25 on the shaft of the impression cylinder of the printing couple. When the arms are lifted,. the card passes through forwarding rollers 7, 7<SP>1</SP> to the creasing rollers. Emerging from the creasing rollers the card passes between the impression cylinder and a printing cylinder 15 carrying a rubber relief printing surface 16. The printing cylinder is geared to the shaft of the last creasing roller group 12 by a chain 22.

Abstract: 1,142,982. Automatic exchange systems. INTERNATIONAL BUSINESS MACHINES CORP. 10 Jan., 1968 [13 Jan., 1967], No. 1372/68. Heading H4K. In a ringing circuit for substations having a line transformer T with equal primary windings P2, P2, the ringing current is directed in parallel through the said windings so that no noise passes across the transformer to the switching equipment. To initiate ringing, a signal at terminal 42 is amplified to turn on a controlled rectifier D1 allowing current to flow from an A.C. source 12 to the ringing equipment 8 and thence to P1, P2. Transistor Q1 is turned on to bring the lower end of P1 to substantially ground potential. D5, D2 serve to discharge the ring capacitor during non-ringing periods. In the off-hook condition, the flow of D.C. turns on Q2 which turns off D1 to inhibit further ringing. At the same time an indication is given at terminal 41 through a dial integrator. The circuit is usefully employed in exchanges provided with solid state switching equipment.

Title: Improvements relating to turbine plant including a boiler with an economiser
Inventor: ZOLLER RONALD ERNEST
IPC: F01K7/44
Filed: 1957-01-18
Abstract: 839,382. Steam turbines. BABCOCK & WILCOX Ltd. Jan. 17, 1958 [Jan. 18, 1957], No. 1879/57. Class 110 (3). [Also in Group XIII] Feedwater from a heater 23, in which it is heated by steam bled from a turbine 12, passes to a condenser 26 for the exhaust steam from auxiliary turbines 11, e.g. for driving fans supplying combustion air to the furnace of the steam generator 10, and the feedwater is thus heated further before passing to the economizer 18 of the generator. The temperature is said to be above that at which condensation will occur in the economizer. Steam from a superheater 19 passes to the fan turbines 11 as well as to the main turbine 12. When there is low loading of the main turbine 12 excessive heating of the feedwater in the condenser 26 is counteracted by reducing the supply of bled steam to the heater 23 by means of a valve 28 having a diaphragm acted upon by the back pressure of the fan turbines 11 through a line 27. At lower loads one of the fan turbines 11 may be tripped out automatically to reduce the back pressure and so reduce the throttling action of the valve 28. In an alternative arrangement for lower loads, a diaphragm valve 29, responsive to the fan turbine back pressure, releases excess exhaust steam, through a conduit 30 to a main condenser 13.

Title: Improvements in or relating to electric annealing, hardening and smelting furnaces
IPC: H05B3/62
Filed: 1923-01-23
Abstract: 192,386. Coradi, O. Jan. 24, 1922, [Convention date]. Resistance furnaces.-In an electric furnace for annealing, hardening or smelting, provided with loosely poured in resistance material 7 such as small coal, the current supply electrodes 5, 6 are positioned in the resistance material so that the current path is parallel to the wall of the chamber or muffle 2 to be heated, the shortest path of the current being thus on the outer surface of the chamber and the longest path being on the outer surface of the resistance material. In Figs. 2, 5, 7 the electrodes 5, 6 are of iron or carbon separated by insulation 4. Fig. 2 is a horizontal cross-section of a vertical cylindrical furnace having a crucible 10 located in the muffle 2 and supported by a movable fire-proof support. The furnace may be arranged so as to be tilted if the crucible 10 is not used. In a modification of Fig. 2, without the crucible 10, the resistance is in the form of a truncated cone. The poured-in resistance material may become more tightly packed at the bottom than at the top, so that the reduction of cross-sectional area toward the top is compensated for by the increase in resistance per unit length at that cross-section to produce a uniform temperature over the surface of the muffle. This condition is essential in annealing and hardening furnaces. Fig. 5 is a vertical cross-section of a furnace having vertical partitions 11 dividing the resistance material into a number of independent zones. Figs. 7 and 8 are horizontal cross-sections of further modifications.
