Patent GB-768395-A (GB)
Abstract: 768,395. Transfer mechanism. OLIVETTI & C. SOC. PER AZIONI, ING. C. Jan. 11, 1955 (Jan. 21, 1954], No. 823/55. Class 106 (1). Transfer mechanism for the totalizer of a calculating or similar machine, wherein each order has transfer conditioning means settable to effect primary transfer into the next higher order, is characterized by advancing means, each positively operated by its associated order for effecting secondary transfer to the higher order simultaneously with its occurrence. All secondary transfers therefore occur simultaneously and with the primary transfers, as these are effected during the transfer phase of operation. As illustrated, the totalizer wheels 14 are first engaged with racks 6, as these are restored after differential setting by a pin carriage 8, and then with toothed transfer rockers 19. These rockers are held by transfer latches 24, each adapted to be tripped by the transfer tooth 16 of the lower order wheel, unlatched rockers moving under the action of springs 22 into an upper position I whence they are restored by a universal bar 30 to enter the primary transfers. According to the invention, each transfer rocker 19 is formed with a lateral projection 20 in register with the lower order transfer tooth 16. If, during lowering of the bar 30 to enter primary transfers, a totalizer wheel passes from " 9 " to " 0 " or vice versa, its transfer tooth moves the associated rocker 19 downwardly to a lower position II by engagement with its projection 20, all rockers so moved simultaneously entering secondary transfers into the higher order wheels. Further transfers which might arise are also effected simultaneously with the lowering of the bar 30 and entry of the primary transfers. A bar 28 holds the rockers 19 at the completion of transfer and pending disengagement of the totalizer from the rockers 19.

Patent GB-2042365-A (GB)
Title: Gas separation
IPC: B01D53/04
Filed: 1979-03-05
Abstract: A pressure swing adsorption (PSA) process for the separation of a component from a gas mixture also containing water vapour, eg the separation of nitrogen from air, employs adsorbers 1 and 2 each having a first stage 3, 3' containing a desiccant adsorbent and a second stage 4, 4' containing an adsorbent which preferentially adsorbs another component of the mixture eg a carbon molecular sieve which adsorbs oxygen more rapidly than nitrogen. Each adsorber is put through a cycle comprising an adsorption step during which the mixture is passed through the adsorber by a compressor 5 and unadsorbed product is withdrawn through a delivery line 11, and a desorption step during which the adsorber is vented to atmosphere through a waste gas line 9. The pressure reached in the adsorber during such venting is the lowest reached during the entire cycle, no vacuum pump being employed. A valved line 12 allows pressure equalisation between the adsorbers. <IMAGE>

Patent GB-2051341-A (GB)
Title: Fluid circulating systems
IPC: F24D3/02
Filed: 1979-11-16
Abstract: A fluid circulating system for instance a hydronic heating system, utilizes a Venturi-type device (20) to effect communication between the circulating system and a storage tank (26). The storage tank, which is maintained at ambient atmosphere pressure, is connected to the throat (20b) of the Venturi. The inlet and outlet of the Venturi are connected to the outlet and inlet, respectively, of a pump (10). The pressure differential between the Venturi throat and the Venturi inlet remains constant. Thus, if the Venturi throat pressure is set so as to be atmospheric during normal operating conditions of the system, when the system pressure drops, the Venturi throat pressure will drop below atmospheric and draw water from the storage tank into the circulating system. Conversely, if the pressure in the system should rise, the Venturi throat pressure would rise above its ambient atmospheric level to thereby vent some of the water from the system back into the tank. <IMAGE>

Title: A combined radar communication system
IPC: H01Q5/45
Filed: 1979-12-10
Abstract: In known systems where a missile is tracked by a monopulse radar and is communicated with by another microwave system it is known to use two main reflectors, one for the tracking system and one for the communication system. The invention provides a single main reflector 1 having, at its focal point a feed 6 for the communications system which transmits messages to and receives messages from the missile. A secondary reflector 22 between the reflector 1 and the feed 6 provides the reflector 1 with a second focal point at which a feed 14 belonging to a monopulse tracking system is located. The tracking system and the communication system operate at different frequencies and the secondary reflector 22 is designed so as to transmit frequencies at which the communication system operates and to reflect frequencies at which the tracking system operates. By employing the invention it is possible to avoid the need for two reflectors 1. <IMAGE>
