Abstract: 907,524. Treatment chambers. VICKERS RESEARCH Ltd. July 26, 1961, [July 29, 1960] No. 26507/60. Class 81 (2). An apparatus for treating patients, such as by X-rays, under a pressure greater than atmospheric comprises a chamber having a shell of transparent material with end caps, one of which is removable to serve as a door. Gas is fed into the chamber to provide the desired pressure. In the form described, the shell 1 is made from two concentric cylinders of transparent acrylic resin, the space between them being almost completely filled with glycerol and, while one end cap 3 is permanently attached to it, the other 4 is made to close against a ring 9 and to be secured in position by nuts 11 on tie rods 10 extending from the cap 3. The cap 3 is mounted on two wheeled supports and there is a single such support below the ring 9. The cap 4 has two wheeled supports and also is attached to a couch running on rails extending along the length of the chamber 1 so that the patient can be conveniently placed in the chamber or withdrawn. An oxygen cylinder is used to supply gas under pressure to the chamber and a control panel provides valves and switches for determining the maximum pressure to be applied and the rate of increase and decrease of pressure. These are effected by a motor-driven valve arrangement, see Fig. 5 (not shown), in which an electric motor applies increasing or decreasing pressure through a spring to a relief valve associated with the chamber.

Title: Improvements in or relating to automatic telecommunications exchange systems
IPC: H04Q3/00
Filed: 1969-05-28
Abstract: 1,224,457. Automatic exchange systems. SIEMENS A.G. 28 May, 1969 [29 May, 1968], No. 26841/69. Heading H4K. Checks are applied to the process of path finding in a simulation network to ensure that a path selection signal resulting from a path finding process corresponds to a free element offered from the simulation network. A further check is applied to ensure that the path selected corresponds to the path requested by a path finding mark on the simulation network that initiated the process. A check may also be applied, after establishment of a selected path, to see if, in response to the path finding mark that gave rise to the selection of the path, the elements seized for the path have been busied out of the simulation network. As shown in Fig. 1 cross-point elements KX1-KXm of switching matrices correspond to commons fX1-fXm in the simulation network WN. Matrices of a following stage are represented by commons fY1-fYn in the simulation network. The cross-points of the switching network may be relays or semi-conductor devices. Path finding in a preceding stage results in the provision of one or more select signals to the rows of the matrices K from a link selector MZLX supplied with offering signals from the simulation network. Select signals from MZLX pertinent to each matrix KX1-KXm are commoned in OR-gates O11-Om1 and supplied as path finding marks to the respective commonsfX of the simulation network, from which they fan out as marks to the commons fY over wires representing the interstage links which, if idle, have contacts bmn closed. Idle links are by this means offered to link selector WZLXY which chooses one and presents a select signal in accordance with the choice to the associated column of matrix KX. If the select signal corresponds to an offered link, a gate from the set U11-Un3 is opened to signal a valid selection over P211. Before proceeding to establishment of the path a device S blanks off selector MZLX so that the select signal from WZLXY is presented over gates O12-Om2 and O1-Om to provide a path finding mark to one of the commons fX. If WZLXY is acting consistently it will provide the same path finding mark as gave rise to the select signal and the coincidence of link offered and select signals at gates U11- Un3 will confirm this. If the device S unmasks selector MZLX, path finding marks are supplied from both MZLX and WZLXY over the common gates O1-Om and, should these marks differ a one-and-one-only detector P7 will signal the fault. Attempts to operate more than one connection or select more than one path are monitored by devices P13, P14, referred to as ambiguity testers. Instead of selecting interstage links as signalled from the simulation network a selection may be made of offered next stage matrices as manifest from marks at commons fY, Fig. 2 (not shown). In this arrangement an allotter selects an offered second stage matrix and a selector arrives at the identity of free interstage links from a knowledge of the matrices offered for the path.
