Title: Improvements in or relating to radio station apparatus
IPC: H03F1/54
Filed: 1954-02-19
Abstract: 758,546. Radio transmitting systems. GENERAL ELECTRIC CO., Ltd., and FAIRNBAIRN, E. P. Feb. 17, 1955 [Feb. 19, 1954], No. 5005/54. Class 40 (5). A radio station comprises a main and a stand-by transmitter 1, 2 and monitoring means 6 for detecting a radio frequency output of the main transmitter to derive a check voltage which, applied to a normally energized relay TA, prevents release of the latter to a second (rest) position, as shown, which would automatically bring the stand-by transmitter into operation. The station may be part of a radiotelephony link, a radio transmission call from a telephone exchange being initiated by earthing, at the exchange, a line ST so that the main transmitter 1 is switched on. Since the relay TA is normally energized by a voltage x the relay TB/2 becomes energized to disconnect the voltage source x from relay TA with a short delay so that, due to the main transmitter output, the relay TA remains energized by the detected R.F. output. But, if the main transmitter 1 has no output, relay TA releases (to its position as shown) so that, relay TB/2 being slower in releasing than relay TA, a further relay TC/4 becomes energized, and is locked by contact tc4. Also contact tc3 so that relay TAR/2 is operated to switch over aerial switch tar1 to the stand-by transmitter. Further, a relay TCA/6 is energized by contact tar2 so that only then is H.T. applied to the stand-by transmitter. The aerial feeder being connected to the stand-by transmitter before H.T. is applied avoids damage to the latter. Speech signals from the exchange over lines L1, L2 are also connected to the stand-by transmitter. A visual indicator and alarm at the stand-by transmitter are also operated by relay TCA/6. Removal of earth potential from ST at the end for call relays TA, TB release as before but relay TCA, TAR and the stand-by transmitter remain operative. Finally, if the stand-by transmitter also fails, a relay TD/4 is energized over contacts ta1, tb1, tc1, and disconnects earth from both the transmitters by opening switch TD4, so that neither transmitter is energized, and a different visual and aural alarm are operated at the relay station. Moreover, warning of failure is given at the exchange because a supervisory lamp dependent on current through lead ST does not glow. When both transmitters are repaired, a reset key 9 is depressed to deenergize relays TD, TAR, TCA. Failure of H.T. supply at the relay station also operates an alarm.

Title: Improvements in or relating to transmission systems for the transmission of pulses
IPC: H04L7/00
Filed: 1965-02-05
Abstract: 1,044,412. Data transmission. PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd. Feb. 5, 1965 [Feb. 8, 1964], No. 5107/65. Heading H4P. To prevent a self-clocking receiver from slipping out of phase consequent upon the reception of a long series of like bits, the transmitter includes coding means for ensuring that such a series does not occur in the transmitted signal, and the receiver includes corresponding decoding means. The received pulses, after demodulation, pass to a sampling circuit. The sampling clock pulses are derived from the bit transitions in the received data by way of a tuned filter. The coding means at the transmitter is designed to translate the input data to a form containing no series of like pulses longer than the decay time of the tuned filter, and comprises modulo-2 adders and a number of delay circuits. In the case of the coding circuit itself generating a series of like pulses a counter, having counted thirty such pulses, causes the last-transmitted pulse to be inverted and retransmitted, i.e. a bit transition is provided, whereby the receiver can be maintained in phase. Following the sampling circuit at the receiver, circuitry similar to that at the transmitter decodes the data to develop a data train identical to the transmitter input.

Title: Controlled release medicaments (and process for producing the same)
Inventor: MILOSOVICH GEORGE
IPC: A61K9/16
Filed: 1966-02-04
Abstract: A controlled release bead, suitable for the controlled release of a medicament on internal administration, comprises (a) a core comprising a uniform mixture of a medicament and a water-swellable colloid and (b) a film coating surrounding and contacting the core, the coating being inert to body fluid, permeable to the diffusion of water, and capable in use of being ruptured by the swelling of the colloid-containing core, whereby in use on prolonged exposure to body fluid, sufficient water diffuses through the coating and causes the core to swell to an extent such as to rupture the coating, thereby resulting in the substantially immediate and total release of the medicament into the body fluid.  The colloid may be starch, starch phosphate, zein, gum arabic, agar, albumin, tragacanth, or gelatin-starch mixtures and is preferably gelatin containing less than 11% by weight of water.  The film coating may be formed from a plastics material, e.g. ethyl cellulose, a chlorotrifluoroethylene or tetrafluoroethylene resin or a vinyl chloride/ vinylidene chloride copolymer.  A pharmaceutical composition comprises a plurality of the controlled release beads and a carrier, e.g. a gelatin capsule, the cores preferably each containing the same proportion of medicament. The water permeability of the film coating of each bead used in a composition may be selected from a progressive series over a predetermined range, thereby resulting in use in the serial rupture of the coatings of the beads and the controlled release of the medicament.  The plastics film coating is preferably applied to the dry core by vertical spray drying.

Title: Improvements in or relating to liquid homogeneous reactor safety overflow system
Inventor: WEEKS IVAN FOREST
IPC: G21C9/00
Filed: 1956-02-20
Abstract: 783,400. Nuclear reactors. NORTH AMERICAN AVIATION, Inc. Feb. 20, 1956, No. 5230/56. Drawings to Specification. Class 39(4). In a liquid homogeneous nuclear reactor a safety overflow system consists of an auxiliary container, connected to the main reactor vessel, both vessel and container being contained within the reactor reflector. When the reactor rate of operation rises above a predetermined level the liquid solvent is decomposed by irradiation to form a gas which urges a part of the fuel solution into the auxiliary container, thereby reducing the fissionable mass in the reactor below the critical value. To restore normal operation of the reactor, the overflow fuel in the container may subsequently be returned to the reactor by a gas bubble pump. During normal operation, the gases generated in the reactor are moved through a vent in the reactor vessel by a gaseous carrier medium pumped into the upper part of the vessel through the auxiliary container. The fissionable material consists of a uranyl salt, enriched with U-235, dissolved in the moderator, water or heavy water. The control rods are boron or cadmium and the pressure vessel a stainless steel sphere.

Title: Improvements in or relating to coiled springs
IPC: F16F1/04
Filed: 1926-02-26
Abstract: 258,483. Barnes, E. Feb. 26, 1926. Helical springs. - A cylindrical portion is connected to another cylindrical portion by an integral junction part having coils of greater size so that some parts of a spring will have greater elasticity coupled in some cases with equal or even greater strength. In the example shown in Fig. 2, the two similar cylindrical portions A, B, A<1>, B<1> are connected by an integral junction piece B, B' having cylindrical and conical parts. In this case, the junction piece possesses greater elasticity but less strength since the spring is wound from wire of uniform gauge. Fig. 5 shows a construction in which cylindrical portions AB, A<1>B<1> are connected by a junction piece BB<1> of varying but larger diameter, the spring being made from wire of varying gauge as shown in Fig. 4. The portion BB<1> is of greater elasticity than the remainder. The variations in gauge of the wire decided upon will determine which of the parts as the strongest.

Title: Improvements in or relating to printing mechanisms for statistical and like machines
Filed: 1931-02-20
Abstract: 373,231. Typewriters &c. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London.-(Assignees of Bryce, J. W.; Bloomfield, New Jersey, and Daly, G. F.; Johnson City, New York, both in U.S.A.) Feb. 20, 1931, No. 5463. Convention date, Feb. 21, 1930. [Class 100 (iv).] Relay type-bar action.-In printing mechanism for statistical and like machines wherein each type-carrying member bears a set of digit type, each zero type is separated from the rest of the type by a blank space or blank type, used for suppression of zero-printing. Normally the mechanism tends to arrest each carrier so that the blank space is at the printing line, but if a significant figure has been set in that, or in a higher denomination the carrier concerned is permitted to move a step further to present the zero type for printing. Each type-bar 229 rises synchronously with the card-reading and when the blank type is at the printing line a universal bail 239 rises to permit counterclockwise rotation of levers 245 (one for each typebar) pivoted at 246 and normally holding contacts 237 open, so that these contacts close. If, however, a bar 229 has been arrested by pawl 236 by reason of a significant figure in that denomination, the bar prevents counterclockwise rotation of lever 245 and maintains its corresponding contacts 237 open. Simultaneously, when the blank type is at the printing line the magnet 233 for that denomination is energized (if not previously energized) to pull rod 234 and allow pawl 236 to engage the rack 238. If, however, a higher denomination contains a significant figure, as at denomination " 7 " Fig. 3, the series circuit for that magnet is broken, pawl 236 is not released and the typebar rises a step further to present the zero-type at the printing line. In Fig. 3 the contacts 237 are connected in series as shown to sockets 561 and line 561a for two four-denominational banks. In the lower bank, for example, the denominations 5 .. 8 are for thousands, hundreds, tens and units respectively. There is a significant figure only in the tens denomination, so that when the blank type of the other bars reach the printing line, the tens contacts 237 are maintained open by the arrested tens bar 229 ; circuits are completed for the thousands and hundreds magnets 233 to throw in their pawls 236 but the circuit of the units magnet is broken at the tens contacts 237 and the units bar 229 rises further to print zero. Specification 373,221, [Group XIX], is referred to.
