Title: Improvements in processes for purifying ethylene and for the production of ethyl alcohol therefrom
IPC: C07C7/148
Filed: 1931-03-12
Abstract: Crude gases containing ethylene intended for the subsequent manufacture of ethyl alcohol by hydration with steam are freed from propylene and other higher olefines by treatment at an elevated temperature, and in the vapour phase with a catalyst comprising a metallic phosphate, whereby the olefines higher than ethylene are condensed.  Part of the higher olefines may be condensed in this way, and the remainder then removed by another treatment, for example, by washing with a mineral oil fraction approximating to kerosene and boiling over 200 DEG  C., or with an ammoniacal cuprous salt such as the formate, acetate, or carbonate.  The treatment with the phosphate catalyst may be carried out at temperatures of 150-200 DEG  C. at atmospheric or at higher pressure, for example, at a pressure of 50 atmospheres, which may be the same as that employed in the subsequent hydration.  Cadmium metaphosphate, which may be obtained by adding the theoretical quantity of cadmium oxide to a 50 per cent solution of orthophosphoric acid and evaporating to dryness, is a suitable phosphate catalyst, either alone or deposited on pumice or the like. According to an example a mixture of ethylene, propylene, and inert gases is passed at atmospheric pressure and at a temperature of 200 DEG  C. over cadmium metaphosphate, the propylene being partly condensed to a mobile oil.  The gas is recirculated over the catalyst until the propylene is removed. Using a pressure of 20 atmospheres, the propylene may be removed by a single passage over the catalyst.

Filed: 1961-03-02
Abstract: 928,242. Switches held set and treed mechanically. SOVEX Ltd. Feb. 22, 1962 [March 2, 1961], No. 7714/61. Class 38 (5). An apparatus for controlling a set of push-buttons a1-a6 &c. comprises a plurality of slidable and rotatable, spring-loaded plungers b each engageable with a push-button; a plurality of locking frames g each engageable by one of a number of projections j on each plunger b; and means for successively disengaging the frames from plungers engaged therewith. Each push-button operates a switch connecting a separate circuit to a common supply. In use, the buttons are set by depressing the corresponding plunger and rotating it until a chosen one of the helically arranged projections j engages the corresponding locking frames g to hold the plunger in its depressed position. The locking frames are then displaced one after another by means of suitable cams, thus releasing successively the plungers held set by each frame. The cams are driven by an electric motor and a further cam on the same shaft controls the common supply so that a pulse of current flows to the push-buttons just before the release of each frame. Thus the first pulse of current flows to all of the selected push-buttons; the second flow to all those remaining after the first frame is released and so on so that a number of selected circuits receive a required number (up to five) of current pulses. Each plunger comprises five identical sections bI-bV mounted on a hexagonal shaft b8.

Title: Improvements in or relating to printing devices for weighing machines
IPC: G01G23/18
Filed: 1939-03-09
Abstract: 512,828. Weighing-apparatus. KRAUT, sen., W., KRAUT, jun., W., and KRAUT, E. March 9, 1939, No. 7717. Convention date, March 9, 1938. [Class 143] Printed records, apparatus for giving.-Relates to the printing arrangements of a pendulousweight weighing machine employing capacity weights for changing the weighing range and wherein the values of the capacity weights are printed together with the values of the normal weighing range .determined by the exploration (by feelers) of a disc (stepped) mounted on the indicator spindle. The invention consists in providing the printing mechanism with a locking device which becomes operative to prevent the taking of a record when as the result of too many or too few capacity weights being added, the stepped disc on the indicator spindle is disposed out of its exploration position (due to the indicating pointer passing beyond its maximum reading but short of its zero reading). In obtaining a printed record upon a piece of paper lying on a platen 43, Fig. 3, a crank handle is rotated thereby causing a transverse rod 17 to move towards the stepped disc 4 followed, under the action of springs 13, by three feelers 9, 10, 11 corresponding respectively to hundreds, tens,and units denominations. The feelers move into engagement with the steps in the disc 4 and at the same time, by means of racks, set the type wheels 32, 27 26. When capacity weights are added to change the weighing range a rod 37, actuated by the changing mechanism (not shown), rocks a bell-crank lever 36 and displaces a spring-pressed rack 33 driving the hundreds printing wheel 32. At the same time an appropriate number of projections 40, 41, 42 on the rack 33 are brought, in known manner, to the right-hand side of a projection 39 on the hundreds feeler 9 so that the subsequent movement of this feeler into engagement with the stepped disc 4 adds on to the hundreds type wheel 32 the appropriate amount due to the normal or pendulous mechanism. Further movement of the crank handle 24 causes a cam 46 actuated through gearing to rock a pressure stirrup 45 and press the paper against the type wheels. If the indicator pointer is located in a non-indicating position in the gap between the maximum and zero readings of the dial, the stepped disc 4 is out of an exploration position and the printing mechanism is locked.by a pawl 50 which engages an elongated recess 53 -in a double cam 52. A spring 55 secured to a feeler 57 enters a second recess 54 in the double cam. The feeler 57 is connected by a spring-pressed rod 58 to the locking pawl 50. When the crank handle 24 is rotated the spring 55 is pressed,out of the recess 54 and swings the locking pawl 50 out of locking position. In the non-exploration position of the stepped disc, a projection 60 on the disc prevents the feeler 57 from moving sufficiently to withdraw the locking pawl 50 and recording is thus prevented.

Title: Oscillation damper
IPC: F16F7/04
Filed: 1951-04-03
Abstract: 698,208. Frictional vibration-dampers. GRANET, C., and ROLAND, G. April 3, 1951 [April 6, 1950; Oct. 19, 1970], No. 7755/51. Class 108 (iii). The rotor 2, Figs. 1 and 2, of a frictional oscillation vibration-damper is made entirely or partially of resilient material and has at least one protuberance or boss 3, the stator 5, 6, 7 having means capable of rendering progressive the friction-damping action for either direction of rotation. In the construction shown in Figs. 1 and 2, the rotor 2 has three bosses 3 spaced at 120 degrees and co-operating with respective, similarly-shaped recesses 8 formed in the stator body 7. On deflection in either direction from a normal neutral position (shown), each boss is compressed as it passes from its recess 8 into an escape recess 10 within which it is able to move freely. Deflection is limited by axially-disposed rotor projections 4 which correspond with similar projections 11 formed on the stator end-plate 6. Friction between the opposed side-faces of the rotor 2 and stator end-platc 6 is adjustable by the action of a nut 12 bearing on angularlyspaced fingers 14. A spring-loaded ball 18 in each finger, co-operates with a respective indexing recess in the nut 12. In a modification, Figs. 5 to 7, two rotor portions 2a, 2b each identical with the rotor 2 of Figs. 1, 2 are rigid, but angularly spaced, with respect to each other, so that a boss 3a on the portion 2a lies equidistant from adjacent bosses 3b on the portion 2b. The stator body 7 is formed with a pair of correspondingly angularlyoriented series of recesses 8a, 8b, each identical with the series of recesses 8 of Figs. 1 and 2. The stator body 7 is also formed with a pair of series of escape recesses 10a, 10b corresponding to the recesses 10 of Figs. 1 and 2. Deflection is limited by the action of an axial projection 4a. The portions 2a, 2b may be formed integrally, Fig. 9 (not shown), and a greater number of portions may be employed in conjuction with a corresponding number of stator recess series. The projections 3a, 3b may be assymetrically disposed in relation to the stator recesses so as to produce an initial friction force in the neutral position. In another form of construction, Fig. 3 (not shown), the bosses may project axially from the side faces of the rotor tn co-operate with recesses formed in side plates secured by bolts to the stator. A plurality of axially-disposed rotors may be assembled on a common operating shaft, Fig. 4 (not shown), each with a respective pair of recessed side-plates. A combination of the constructions of Figs. 1 and 3 (i.e. having both peripheral and axially-disposed bosses) may be employed. The rotor may be of natural or synthetic resin.

Title: Improvements in or relating to automatic weighing apparatus
IPC: G01G1/28
Filed: 1925-03-25
Abstract: 231,508. Durand, P. March 28, 1924, [Convention date]. Loose-weight apparatus.-In an automatic weighing-scale of the type in which the beam is automatically balanced by electrically actuated means, weights are deposited on or removed from a weight-pan by an electromotor, the circuit of which is controlled by two electromagnets energized through beam-contacts, the extent of rotation of the motor being controlled by cam means brought into action by the electromagnets. The invention comprises a pointer 3, Fig. 1, which indicates on a chart 4 the amount by which the load on a goods-tray 1 exceeds that on a weighttray 2. Three equal weights 7 are normally suspended on hooks 9, but may be lowered on to the tray 2 by cams 6 mounted on a shaft 5 adapted to be rotated by a motor 14. One weight 7 is deposited upon the tray 2 for each quarter of a turn of the shaft 5, corresponding to one revolution of the motor 14. An arm 11 on the shaft 5 is adapted to engage a stop 12 and thereby to limit the shaft's rotation to one revolution. Should the pointer 3 pass beyond the chart to the position 3b the support of the goods tray 1 closes a switch 20 in circuit with a solenoid 19. The solenoid thus energized forces the core 22, Fig. 4, upwardly, thus closing the motor switch 29 and simultaneously causing the nose 26 of an arm 25, Fig. 5, to assume the position 26<a> with respect to cams 27, 28 mounted on a disc 18 on the motor shaft. The motor completes a revolution during which a weight 7 is lowered on to the plate 2, and is then stopped by the cam 28 forcing the arm 26 back into its original position. Should one weight 7 be insufficient the operation is repeated. In the event of the three weights being insufficient, the arm 11 opens a safety switch 21, Fig. 1, in the motor circuit. When the load is removed from the goods tray 1, the operation is reversed by the switch 20<1> in circuit with a second solenoid 19<1>, which operates a switch 29<1> in a reverse circuit of the motor and actuates an arm 25<1> engaging cams on the reverse side of the disc 18. A second safety switch 21<1> operating in a similar manner to the switch 21 is also provided.

Title: Improvement in coke oven plant
Inventor: SUMMERS WALTER THORNTON
IPC: C10B39/18
Filed: 1960-03-08
Abstract: 983,739. Controlling flow of hot coke. COAL INDUSTRY (PATENTS) Ltd. June 8, 1961 [March 8, 1960], No. 8165/60. Heading B8S. Carriage 3 reciprocates along rails 2 and carries a cross carriage 10 which moves transversely to engage and open one of the gates 1a to 1m which pivot about pivots 7a-7m to control the flow of hot coke from a coke oven down the sloping shoot 8. Cross carriage 10 is moved transversely to the direction of movement of carriage 3 by ram 4, the cross carriage carrying arms 13 pivoted at 17 so as to engage the gates 1a and 1b by means of rollers 14 and 15 contacting cams 6a and 6b. Carriage 3 is reciprocated by a rope driven by the winch 26 driven by motor M5. The carriage carries a rockable shaft 46 and the shaft carries probes P1 and P2 which move from a horizontal position to a vertical position in the downwards direction so as to contact the coke flowing over shoot 8. Shaft 46 also carries cam discs C1, C2, C3, C4 which control an electric circuit. Probe P1 measures the height of the coke and probe P2 measures its temperature. Normally carriage 3 moves from left to right whilst shaft 46 rocks to permit the probes P1 and P2 to move from the horizontal position down to the vertical position to engage coke. When probe P1 engages a layer of coke it operates the electric circuit to stop the carriage 3 and to cause ram 4 to move the cross carriage 10 transversely so as to cause an arm to open a gate to discharge the coke. The probes continue to rock and when the coke has been discharged the probe P1 operates the electric circuit to cause the carriage to move forwards whilst withdrawing the cross carriage 10. Alternatively probe P2 which oscillates together with probe P1 detects the temperature of the coke and if this is too high causes the electric circuit to cause the movement of the cross carriage 10 to close the gate to retain the hot coke within the shoot. When the carriage has progressed to the right it is then returned by winch 26 to its left position with the probes P1 and P2 in the horizontal non-operating position. Weigh beams 44a (not shown) may be disposed beneath the discharge belt 47 so as to control the electric circuit such that when the weight on the belt is too great the cross carriage 10 is operated so as to close a gate to retain the coke.

Insulators 4 for the internal equipment 2 of an electrostatic precipitator are mounted in frames 8 which are suspended from the top 10 of a roof beam 6 so as to be vertically movable relative thereto, the roof beam, which acts as a support for the internal equipment, being liable to bend where the precipitator is in operation. The equipment 2 is suspended from the insulators 4 by rods 3 and antideposit skirts 5 prevent dust from being whirled into the insulators. The frames 8 are suspended by screw means 9 from the top 10 of the roof beam and are guided when raised or lowered by rods 11 and skirts 15, Fig. 2 (not shown). A wire 12 stretched across the roof beam provides a level datum. Sighting marks 13 at the upper ends of the screw means 9 permit any deflection of the beam and consequent lowering of the insulators to be detected. When this occurs, nuts 14 are turned and the frames raised until the lighting marks are in register with the wire 12. Alternatively, changes in level may be detected by tube water level indicators or detectors of the photographic, ultrasonic or electrical beam type. Automatic means may be provided for lifting or lowering the frames under the control of electrical regulating means.

In the spherical fuel element illustrated, the wall 2 of a spherical cavity within a spherical graphite body 1 is lined first with a layer of coated UC particles to form the fissile material 3, and then with two or three layers of coated ThC to form the breeder material 4. The remainder of the cavity is packed with a graphite mass 5, preferably in powder form, through an aperture in the body 1 which is subsequently sealed with a graphite plug 6. 1 g. U-235 and 15 g. Th-232 are provided per fuel element. With progressive fuel consumption, the energy production is transferred from the fissile material 3 to the breeder material 4 which has in the meantime been transformed into fuel by neutron bombardment. It may be advantageous to introduce a small number of breeder material particles into the layer of fissile material particles in order to "dilute" the fuel somewhat. The graphite body may alternatively be rodshaped in which case it is provided with a graphite plug at each of its ends in order to seal the cylindrical cavity.
