Title: Improvements in or relating to cash registers
IPC: G06C27/00
Filed: 1959-04-10
Abstract: 885,588. Cash registers. STANDARD ELEKTRIK LORENZ A.G. April 10, 1959 [April 17, 1958], No. 12218/59. Class 106 (1). A cash register is controlled by a device which allows operation of the register only when a voucher or ticket is correctly positioned in the device. Tickets 5, Fig. 2, are attached to articles to be sold, and when a sale is effected, the bottom half 6 of the ticket, which bears the necessary data in ordinary characters and in a punched code, is torn off and placed into a slot in a receiving member 2, Fig. 4, and drops on to a retaining fork 8. The member 2 is then manually pressed downwards to effect the closure of contacts 12 via an arm 11, and is latched by a portion 10 of a lever 14 which is pivoted anticlockwise. Simultaneously, pins 18 are pressed forwardly against the front of wall 19 of the member 2. A relay 25 is then energized from a source 26 via contacts 27, 12, the pins 18 and wall 19. A contact 29 is thus closed and the printing circuit of the cash register (not shown) is prepared. The cash register is now operated normally, the restoring button closing a contact 30 to energize a relay 31 whose armature 17 is attracted to rock the lever 14 thereby disengaging lever 9 and moving the fork 8 to the right to allow the torn-off ticket 6 to fall into a box 32. The lever arrangement is spring returned to its initial condition. If a torn-off ticket 6 is wrongly inserted, contacts 13 remain closed to energize the relay 31, whose contacts 27 open the energizing circuit for the relay 25. The armature 17 is rocked thereby preventing displacement of the fork 8 to the right and hence preventing the wrongly inserted ticket from dropping into the box 32. If a ticket is not completely inserted into the member 2, the pins 18 fail to contact the wall 19, thus preventing operation of the relay 25. The tickets 32 are all orientated in the same way and may be fed into a tape punching machine to transfer the data on the tickets to a tape.

Title: Improvements in or relating to valve mechanisms
IPC: F16K31/524
Filed: 1957-04-15
Abstract: 862,566. Fluid-pressure servomotor control systems; valves. SOC. RATEAU. April 15, 1957 [April 28, 1956], No. 12224/57. Class 135. [Also in Group XXVI] Inlet valve gear for a steam turbine of the kind in which a plurality of valves are operated sequentially by common control means has independently operable governing means for at least one of the valves for over-riding the action on that valve of the common control means. Thus, should the turbine be required to operate with a load such that one valve remains partially open, causing loss of efficiency by throttling action, the valve with the governing means may be closed, whereupon, to obtain the power required, the common control means is caused to open one of the other valves to a greater extent. Fig. 2 shows inlet valves S operated in sequence by a servomotor SV, constituting the common control means, acting through gearing Z, E, a cam-shaft A, and a cam follower L associated with each valve. For enabling a valve to be operated independently of the setting of the camshaft the valve stem is formed with a hollow upper part U, Fig. 3, in which is slidably but non-rotatably mounted a rod T which engages the cam follower L. The upper end of the rod T is screw-threaded and engaged by a nut E which can be rotated by an electric motor acting through worm gearing. Upward adjustment of the rod T by the motor M allows a spring R to close the valve. The governing means may, alternatively, act by adjusting the pivot point R 2  of the follower L.

Title: Improvements relating to the manufacture of alcohol
IPC: C07C29/141
Filed: 1917-08-25
Abstract: In the production of alcohol by catalytic hydrogenation of aldehyde in liquid form, the catalyst may be platinum black obtained by reducing chloroplatinates with formaldehyde and precipitating with alkali, or nickel obtained by precipitating the nitrate with alcohol and reducing at temperatures below 100 DEG  C.  In the production of alcohol by catalytic hydrogenation of aldehyde vapour, the catalyst (nickel, platinum &c.) is supported on a porous carrier; for example, pumice is impregnated with a solution of a nickel or platinum salt, dried, and reduced; or nickel nitrate solution is mixed with a solution of sodium silicate or magnesium sulphate, the mixture evaporated to dryness, heated, and reduced.  The hydrogenation may be effected in iron cylinders containing the porous material impregnated with catalyst; the mixture of aldehyde vapour and hydrogen is preferably admitted at the bottom and the alcohol formed distils off at the top.  Or a series of vertical iron tubes connected at top and bottom to a collector may be used, the ends of the tubes being provided with perforated plates to ensure proper distribution of the reacting gases.  Specification 108,856 is referred to.

Title: Reducing the oxide and salt content of the feed water in a steam-generating unit
Inventor: LAQUEUILLE CLEMENT ROBERT JOSE
IPC: F01K21/06
Filed: 1962-03-30
Abstract: 969,247. Feedwater supply systems. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. March 30, 1962, No. 12378/62. Heading F4A. Feedwater for a steam generator is purified by diverting part of the main stream into a circuit in which the circulating water is partly evaporated at one point and the resultant steam and water separated at another point the steam being returned to the main feedwater stream and condensed in it, thus reducing the concentration of impurities, while part of the circulating water containing an increased concentration of impurities is bled off to drain and part is recirculated. The process may be repeated as required in any number of stages at progressively increasing pressure levels to obtain the desired degree of purity. Feedwater is supplied through low-pressure stage 50 of a pump 14 and line 57 to a mixing condenser 51 having a deaerator 52 and leaves the condenser through line 58. Part of the stream of feedwater is diverted from this line through lines 60 61 to a tube-bundle 54 in the steam generator 1 and is partly evaporated therein, the resultant steam and water being separated in separator 53. The steam is fed to the mixing condenser 51 where it is condensed in the main feedwater stream thus reducing the concentration of impurities while the water which contains an increased concentration of impurities is partly recirculated and partly bled to drain through a line 65. As shown, the main feedwater stream returns through line 106 to a high-pressure stage 100 of the pump 14 and the cycle is repeated at a higher pressure in mixing condenser 101, tube bundle 104, steam separator 103 and associated lines before the feedwater enters the steam generator through line 109. The heat content of the various streams of bleed water may be partly recovered in combustion air heaters 105, 55 and the pressure utilized in a turbine 12 which assists in the driving of the pump 14. Specifications 953,597 and 969,246 are referred to.

Patent GB-768921-A (GB)
Title: Improved hydroforming process
IPC: C10G35/14
Filed: 1955-04-29
Abstract: Hydrocarbon fractions boiling within the naphtha range are hydroformed in contact with catalysts consisting essentially of molybdic oxide dispersed upon zinc aluminate spinel in a fluidized solids reactor system in which the catalyst is continually recirculated and regenerated by burning off carbonaceous deposits, by contacting the hydrocarbon fraction in admixture with hydrogen-rich recycle gas under conversion conditions and in the substantially complete absence of water.  Recycle gas is contacted with an adsorbent such as alumina gel or silica gel before return to the reaction vessel, and both the naphtha feed and also the regenerated catalyst are separately dried.  In an example, an East Texas virgin naphtha of boiling range 200-330 DEG  F. was contacted with a catalyst containing 10 per cent by weight of MoO3 on a zinc aluminate spinel at 50 pounds per square inch, 900 DEG  F., and with 1500 cubic feet of recycle gas passing through per barrel of feed.  Yield was increased by keeping the water content below 0.5 per cent by volume.

An exchange system provides a four-wire connection between two-wire networks, and the overall attenuation in each direction in the four-wire connection is measured and, if necessary, adjusted to a predetermined value, the routing digits indicating to a control circuit whether this measurement is to be made and what the value of the attenuation is to be for a particular connection. In response to a signal from the control circuit, a link containing measuring and regulating devices is inserted into the connection in the exchange at each end and a pilot signal of predetermined strength is sent over the connection in each direction, causing adjustment of each receiving link to give the required overall attenuation. A record, e.g. on punched cards, is made of connections with unsatisfactory attenuation levels, which may be held to facilitate the location of faults and the establishment of alternative connections.
