Title: Improvements in or relating to electrical signalling systems
IPC: H04W84/02
Filed: 1947-04-23
Abstract: 625,483. Radio signalling. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. April 23, 1947, No. 10866. [Class 40 (v)] Relates to a radio signalling system, in which communication between two of a given number of stations is established over a selected channel, the number of available channels being less than the number of stations. Means are provided at a first station, whereby on receipt of a signal from a second station, a channel identifying signal is transmitted which conditions the second station for communication over the selected frequency channel. The Figure shows six mobile stations, each comprising a transmitter and a receiver, and a static station having a transmitter and receiver associated with a guard channel, and with each of three communication channels. If say, mobile station 3 wishes to communicate with the static station, the receiver R3 monitors the guard channel on frequency f1, and if this is free, transmitter T3 transmits a tone modulated signal characteristic of mobile station 3 at frequency f2. On receipt of this signal, the static station transmitter Ta retransmits this tone modulation at frequency f1 to indicate to the mobile station that its first transmission was received, and this is used to condition the mobile station for the next signal from the static station, which indicates the channel to be used for communication. This channel identifying signal may consist of a number of impulses which automatically operate the tuning means of the mobile transmitter T3 and receiver R3' as described in Specification 572,918. Communication may then be established at frequency f3 between T3,R3 and Tc,Rc. If the various controlling signals are not correctly received, the mobile station apparatus recommences the sequence of operations. Means such as a uniselector device, may be used to indicate engaged channels at the static station. If the static station wishes to call say, mobile station 3, transmitter Ta first transmits a tone on frequency f1 which operates means at all the mobile stations to prevent them from initiating calls. This tone is then interrupted to form the impulse signal characteristic of mobile station 3, and means such as a. uniselector are provided so that the selected mobile station is conditioned to receive the next channel identifying signal while the remaining mobile stations revert to their normal stand-by condition. A calling device may be operated at the required mobile station.' The equipment at the static station may be extended to a telephone exchange, and the mobile stations may then be provided with dialling equipments for use after a channel has been allocated. The invention may be applied to the case of an aircraft wishing to communicate with a number of ground stations in different areas. The guard channel frequency is made common to all the ground stations, and the system is used to set the aircraft equipment to the particular frequency which the ground station is using at that time. More than one guard channel may be provided.

Title: Improvements in a method of making castings
Inventor: SYLVESTER EDMUND QUINCY
IPC: B22D18/04
Filed: 1953-04-21
Abstract: 726,355. Casting-machines. GRIFFIN WHEEL CO. April 21, 1953, No. 10946/53. Addition to 718,744. Classes 83 (1) and 83 (4). In casting, particularly wheels, molten metal from a reservoir is forced through a tube and into a gate in the bottom of a mould having separable top and bottom sections, the gate is closed by a plunger valve after the mould cavity is filled, and after solidification of the metal the casting is lifted from the mould by exerting a lifting force on the plunger valve. The apparatus is substantially the same as that described in the parent Specification which is referred to. The plunger valve 122 comprises a tube 130 and a plug 134 of, e.g., iron or ceramic, and a seat portion 126 of, e.g., ceramic. The tube is preferably filled with sand. After removal of the poured mould from the pouring tube 22 by the crane 90, and after the metal has solidified, a pin is inserted in one of the holes 128 in the stopper above the upper surface of the cope 64, and the cope is elevated, as by jacks, until it is lifted from the casting, and the casting is lifted from the drag by the plunger 122 when the cope abuts the pin. The casting is thereby suspended between the cope and the drag so that as it cools it may contract radially. Thereafter the upper end of the stopper is cut off, the plug 134 knocked out and the sand allowed to drain out, and the seat portion 132 knocked off. Dividing by fusion.-The central portion of the casting with the stopper is finally cut out by a torch 140 to form an axle hole, the casting 138 being mounted on a rotatable table 139.

The link ends are held in the slots, in the active position shown, by springs, and are moved towards the pivots 25 by any desired means such as Bowden mechanism operated by the driver.
Patent GB-372911-A (GB)
Title: Process of and apparatus for sterilising liquids
IPC: A61L2/238
Filed: 1931-04-14
Abstract: In oligodynamically sterilizing beer or other liquids, the liquid is passed over a plurality of oligodynamically active metallic surfaces so that those surfaces which have become inactive can be cut out of the circuit for reactivation whilst maintaining the sterilization at full efficiency.  The reactivation may be effected by cleaning mechanically and blowing air therethrough, or electrically, or both; for example the liquid may be passed through tubes or tubular units internally coated with the active metal, preferably silver, an electric current being passed between each tube and a wire or another tube disposed concentrically therein.  To accelerate the sterilization, more particularly with beer and similar liquids, heat is also employed, the temperature being below that of sterilization and below that at which the protein content of the liquid coagulates or other deposition from the liquid occurs, e.g. below 70 DEG  C. with beer. To prevent escape of gas and further to accelerate the sterilization an increased pressure may be used, change of pressure being obtained by varying the cross-sectional area of the tubes at one or more points.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also maintaining the activity of the metallic surface by continuous or both continuous and intermittent treatment during the process.  This subject-matter does not appear in the Specification as accepted.
