Abstract: 541,647. Delivering tickets &c. automatically from strips. WESTINGHOUSE BRAKE & SIGNAL CO.; Ltd., BURNETT, W. E., and DIXON, S. M. Feb. 9, 1940, No. 2527. [Class 27] Coin-freed machines which print a ticket, cut it off from the roll of paper and deliver it on the insertion of the coin, are fitted with special delivery means comprising a pair of rotatable delivery rollers between which the ticket passes and is nipped, one roller being positively driven and the other being pressed against the ticket and rotated by friction therewith. Also retaining pawls or clips are provided to hold the severed ticket from falling after passing the delivery rollers, until it is grasped by the purchaser. Fig. 1 shows a driven flanged roller 2 over which the strip 13 passes. The knife blade 3 is mounted in a vertically-sliding block 4 which also carries a pair of pivoted arms 5 supporting the shaft of the upper roller 6. When the knife descends to cut off the printed ticket from the strip, it carries the roller 6 downwards to nip the strip against the lower roller with a compressive force supplied by the spring 7. The strip is thus fed forward to the spring- controlled' pawls 10 which retain the rear portion until the ticket is withdrawn by the purchaser.

Title: Improvements relating to synchronising couplings for conveying or preventing rotary motion
IPC: F16D45/00
Filed: 1939-01-26
Abstract: 525,683. Variable-speed gearing; free-wheel clutches. SINCLAIR, H. Jan. 26, 1939. No. 2762. [Class 80 (ii)] In a synchronizing coupling such for example as described in Specification 410,083 and 486,589, a subsidiary ratchet drive includes one or more pawls mounted on the first member 17 or on the intermediate member 20 and co-operating with teeth on the other member normally to perform a synchronizing function and to slip on the application of excessive torque. The coupling, Fig. 1, is inserted between an engine and a change speed gear. The input shaft 10 carries an internally toothed wheel 17 and a planet carrier 13. An internal wheel 15 is mounted on an output shaft 16. A sleeve 11 carries a sun wheel 12 and a right-hand steep pitch thread on which operates a sleeve 20 with a toothed flange 22 engageable with teeth 18, 18A on the wheel 17 and teeth 23 on a fixed ring 24. Spring- pressed pawls 25 on the flange 22 point in the direction of rotation of the shaft 10. The teeth 18, 18A are short and long respectively and the pawls have inclined noses, Fig. 3, not shown, to allow slip on the application of excessive torque. Oppositely arranged pawls 32 also are mounted on the flange 22. The sleeves 11, 20 can be locked by sliding keys 37, 40 on a sleeve 34 operated by the selector control means 36. On directdrive at low speed the sleeves 20, 34 are in the left-hand position, the teeth 22 engaging the teeth 18, 18A. To change from low to high speed, the sleeve 34 is urged to the right and the engine is retarded. The speed of the sleeve 11 drops quicker than that of the wheel 17 and the sleeve 20 moves to the right to disengage the teeth, 18, 18A. The pawls 25, 32 ratchet over and as soon as the sleeve 11 reverses a pawl 32 engages the teeth 23 to move the sleeve 20 to its right-hand position where it is locked. The engine is then accelerated. If when the engine is at rest a high speed gear is preselected by moving the selector control means 36 to the right and the engine is started pre-ignition would cause the shaft 10 to rotate backwards, The wheel 20 is moved to the right by engagement of the teeth 18, 18A, 22. When the wheel 20 reaches the neutral position the pawls 32 engage the teeth 23 and stop rotation of the wheel 20 while a pawl 25 is still in engagement with the teeth 18A. Owing to the obliquity of the faces of the pawls 25 they disengage automatically from the teeth 18A should the torque become excessive and prevent the transmission of reverse torque to the fixed ring 24. In a modification, Figs. 4, 5, 6, not shown, the pawls 25 have contacting surfaces tangential to the path of displacement and are mounted on a spring-pressed ring engaging' the wheel 22 by serrations which allow slip on overload. The pawls may be movable circumferentially.

Abstract: 235,108. Van Dyke, G. M., McNally, T. J., and MacDougall, H. K. Jan. 30, 1925. Calendars.-A monthly calendar is adapted to be mounted on the hour-hand of a clock and a pointer is operated by gravity-controlled mechanism as the hand rotates to indicate the date. An extension 15<1> is attached to the hour hand 15 of the clock 13 by clips 26, 27 and carries a pintle 16 on which are rotatably mounted discs 17, 19 and a wheel 20 with an internal gear of 98 teeth. Meshing with this internal gear is a wheel 22 having 91 teeth, this wheel being mounted on an enlarged eccentric part of the pintle 16. The wheel 22 and disc 19 are provided with weights 23, 25 respectively which cause them always to hang in the same position and the disc 17 engages frictonally with the disc 19 so as to rotate with it. On the disc 19 are printed the numbers of the days of the month in seven radial columns corresponding with seven divisions of the disc 17 marked with the names of the days of the week, and the wheel 20 is provided with a pointer 24. In twelve hours the disc 19 and wheel 22 make one revolution anticlockwise relatively to the spindle 16; the wheel 20 makes thirteen-fourteenths of a revolution and therefore the pointer 24 travels clockwise relatively to the disc 19 through a space equivalent to half a day. To adjust the calendar at the end of the month the pointer 24 is turned thirteen-fourteenths of a revolution clockwise for every half-day it is desired to set the pointer back. In a modification a set of twelve discs is provided each marked with numerals for a particular month and adapted to be attached to the disc 19 by hooks 37, the numeral 1 on each disc being arranged to follow the numeral for the last day of the month set out on the preceding disc. At the end of each month the disc for that month is removed so as to expose the disc for the following month.

Title: Method and means for generating electricity and vapourising a liquid in a thermal power station
Inventor: MARGEN PETER HEINRICH ERWIN
IPC: F01K3/08
Filed: 1970-01-20
Abstract: 1299773 Steam generation ATOMENERGI AB 20 Jan 1970 [20 Jan 1969 5 May 1969] 2779/70 Heading F4A [Also in Division B1] High-pressure steam from source 1, which may be a nuclear reactor cooled by boiling water, is supplied to turbine 2a, 2b which drives electric generator 4; but when the demand for electric power is low, some of the steam is taken off from the high-pressure stage 2a of the turbine in order to heat the feed Liquid of a multi-stage evaporator 16a ... 16f which is suitable for producing fresh water from salt water by distillation. The salt water, supplied through conduit 21, is preheated in stages 15f ... 15a by the vapour from the evaporator. The plant also comprises a liquid-container 29 connected by conduits and valves to the preheating conduit between stages 15b and 15c. When the demand for electric power is low, a mixture of salt water from stage 15c and salt water withdrawn from the lower part of container 29 is passed through conduit 17 to heat exchangers 10 where it is heated by the steam taken from turbine stage 2a, some of the hot mixture then being introduced into the first stage 16a of the evaporator while the remainder is passed through conduit 30 into the upper part of container 29. When the demand for electric power is high and all the steam has to be utilized in the turbine, preheated salt water from stage 15c is passed into the lower part of container 29 and hotter salt water from the top thereof is supplied through conduit 30 to evaporator stage 16a. Container 29 serves as a heat-accumulator so that the evaporator can operate continuously. If, during a period of intermediate demand for electric power, the excess capacity of the reactor is exactly that required to supply the evaporator with heat, then no liquid is allowed to pass into container 29. The direction and quantity of liquid passing through the container is adjusted with valves 34-37. The temperature-difference between the hot and cooler liquid in container 29 should be at least twice the difference in temperature between two adjacent evaporator stages. The steam from low-pressure turbine stage 2b flows to condenser 5; and the condensate therefrom and that from heat-exchangers 10 is punped back to the reactor. Fresh water, produced in the evaporator, is withdrawn from the plant through conduit 25.

Filed: 1952-02-05
Abstract: 710,199. Digital electric calculating apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 5, 1952 [Feb. 5, 1951], No. 3041/52. Class 106 (1) Electrical multiplying apparatus comprises means' for sensing and registering in electrical circuits all the digits of two factors simultaneously, circuits controlling electromagnets associated with relay selectors, such as cross-bar switches, and connected so that when the digits of the factors to be multiplied are applied to the appropriate electromagnets contact indications are produced representing all the partial products simultaneously, and an arrangement for adding the partial products to give a final product. The digits of the factors to be multiplied are read simultaneously from a record card HK, Fig. 2, by known sensing means comprising ten plungers for each card column, those plungers which pass through holes in the card being brought into contact with a positive plate PL1, Fig. 3, by a cam AK1. Thus, number bar magnets Sl ... S9, in banks corresponding with the orders of the digits read from the card, are energized and the contacts opposite each energized magnet are operated. The cross-bar switches operated by the multiplicand digits (e.g. 4752), Fig. 2, are so interconnected with those operated by the multiplier digits (839) that circuits repre - senting the partial product digits are completed. The energized lines representing the partial product digits pass through a series of electromagnetically-controlled adding networks, Fig. 5, in order to derive the final product. A system of coding is employed in the adding devices. An energized line from the partial product tables entering at bottom L.H. of Fig. 5 (say "9") would tend to operate a magnet AR2, indicating that the digit exceeds " 4," but if the digit from the preceding adding circuit also exceeds " 4 " (say " 7 "), a line X is energized as well as the appropriate line (" 2, 7 ") at top L.H. of Fig. 5, and this completes a circuit which opposes the effect on the magnet AR2. Magnet AR1 is operated by the energized "9" line, and the resulting transfer of contacts directs current to magnet MR5 which, upon energization, connects the incoming "2, 7" line to the outgoing "1, 6" line at the RH side. Also, via a rectifier L3 and a closed contact of MR5, voltage appears on the outgoing X line, indicating the digit " 6 "; voltage also appears on line C indicating a tens carry. The carries are added in between each stage by simple relay-controlled circuits, Fig. 6 (not shown). The final product may be indicated on a tabular arrangement of lamps or by punching devices.

Abstract: A process for the treatment of hydrocarbon fractions boiling above 150 DEG C., e.g. petroleum fractions which may boil in the range 150 DEG -450 DEG C., and which may contain 0,1% or more of sulphur, comprises contacting the fraction in the presence of hydrogen with a catalyst comprising a Group VIa metal, a refractory oxide support, and boron, at a temperature of at least 700 DEG F., but below that at which more than 20% weight of the feedstock is cracked to material boiling below 150 DEG C., a pressure of at least 100 psig, and a space velocity not exceeding 8,0 v./v./hr., and recovering a product boiling above 150 DEG C. having a pour point at least 5 DEG F. lower than the pour point of the feedstock, the temperature and space velocity being correlated to give said lower pour point.  The catalyst may also contain a Group VIII metal, and the support may be a metal oxide from Groups II, III and IV of the Periodic Table. Preferably the support is alumina containing 5-25% of other oxides, for example silica, titania, zirconia, beryllia.  The preferred catalyst is a cobalt-molybdenum catalyst. The catalyst may be prepared by impregnating alumina pellets with ammonium molybdate, calcining, impregnating with boric acid dissolved in isopropyl alcohol, drying, and calcining. Alternatively some or all of the catalyst components may be slurried with alumina hydrogel before forming into pellets, the remainder of the components being added after pelleting and before calcining.
