Title: Double-Walled Conservatory
IPC: A01G9/14
Filed: 1967-12-07
Abstract: In a double-walled horticultural conservatory or greenhouse, inner and outer metal framework members 2, 3 are covered by sheets of glass 4, 5 and spaced apart by stays 1 to define therebetween a space through which hot or cold air and/or water is circulated to produce and maintain the required temperature and hygrometric conditions within the greenhouse. The inner glass wall has a gap 6 at its apex, thus communicating the space with the inside of the conservatory. Pipes 7, 8 are situated adjacent the gap 6 to spray hot or cold water over the inner wall, this water being collected in tanks 10 for recirculation by pumps 9. Reversible fans 11 deliver air to or extract air from the conservatory through said space as required, to ensure suitable ventilation. Gas or oil burners (not shown) are provided to heat the water in the tanks 10, and the combustion gases from said burners may be passed into the space if required for additional heating. Thermostats and hygrostats automatically control the operation of the fans, pumps and burners to maintain the required conditions. The amount of light entering the conservatory can be reduced by spraying water tinged with colour into the space between the two glass walls. In an alternative embodiment (Fig. 2, not shown), the spraying pipes together with associated atomizing nozzles (81) are located adjacent the tanks (101). Air is introduced at this point and entrains some of the water, the moistened air then passing up through the space and into the conservatory.

Title: Holder for liquid make-up
IPC: A45D40/26
Filed: 1968-03-27
Abstract: A container comprises a neck and a brush mounted on a closure for the container, the brush being protected by a tube. The tube and brush are slidable relative to each other so that when the brush is removed from the container it projects from the tube. In one form a container 1, of metal or plastics and for, e.g. cosmetics, has a brush 23, mounted by means of its stem 19 on a button 25 in a closure 2, protected by a tube 18. The closure 2 can be unscrewed from a neck 7 of the container, inverted, and screwed back on to the neck by means of a thread 31, whereupon the neck 7 abuts the button 25 and causes a spring 28 to be compressed, so effecting the projection of the brush 23 from the tube 18. Reversing this operation allows the tube 18 to be spring returned to the position shown, protecting the brush 23 when it is pushed through a resilient sealing gland 12 and replaced in the container 1. The gland 12 wipes excess liquid from the tube when removing the brush and a sealing ring 33 prevents leakage through the tube 18 into the closure 2. In modifications, turning an end-knob (63), Fig. 5 (not shown), or a cylindrical easing (107), Fig. 10 (not shown), around the closure, acts through diametrically opposed lugs engaged in longitudinal slots (82 or 82a) and helicoidal grooves (83 or 83a), and causes the protecting tube to slide along the brush. In another modification, the protector tube (75), Fig. 13 (not shown), is fixed on a sleeve (117) which slides between shoulders (122, 125) in the closure, where it is retained in brush covering and uncovering positions.

Title: Process for Producing Urea
IPC: C07C273/04
Filed: 1968-09-27
Abstract: Process for the production of urea which comprises feeding ammonia and carbon dioxide into a reactor, reacting the ammonia and carbon dioxide so as to produce an effluent aqueous solution of urea contaminated with ammonium carbamate, splitting the latter into NH 3 and CO 2 , stripping in a stripper the products of the splitting from the said aqueous solution in the presence of a stripping agent selected from ammonia and carbon dioxide so as to produce an aqueous solution of urea substantially free from ammonium carbamate, condensing the products which have been stripped and recycling the condensed products to the reactor by entraining the condensed stripped products in the ammonia or carbon dioxide which is fed to the reactor. The stripping is usually carried out in a single stage at a high pressure, preferably from 80 to 200 kg/cm.2, and usually at a temperature of from 160 to 250 C. The stripper may be positioned so that the effluent aqueous solution falls into it from the reactor under the force of gravity.

Title: Data processing equipment
IPC: G06K/
Filed: 1977-03-04
Abstract: In order to simplify the charging and accounting procedures in a telephone network and, at the same time, to carry these out in a more reliable manner, the system exhibits a multiplicity of switching devices (11, 12, 18 21, 22, 28 31, 32, 38) with keyboards and display devices. These are connected group by group to control devices (10, 20, 30) for the user which respond to commands keyed in in order to obtain data from peripheral storage devices and to record details of the telephone connections on magnetic tape. Each control and peripheral device exhibits microprocessors for controlling the individual functions and carrying out tests which determine the operating states of the devices and generate relevant display signals. All these devices are connected to a monitor (6) for recording these display signals. Each device can exhibit a monitoring clock generator with a counter. The latter is regularly incremented and periodically set to zero, responding to a software command. Thus, when a central processing device enters a software loop, the counter exceeds a threshold value and generates a signal indicating the presence of such a loop. The same timing generator can also reset the central processing device into a starting position and delete all data recorded as consequence of a program execution up to this time. Finally, there can be a diagnostics device so that a technician can carry out routine checks of the individual devices.
