Abstract: 1422619 Burglar alarm systems ELECTRICITE DE FRANCE 6 Sept 1973 [14 Sept 1972 21 Aug 1973] 41946/73 Heading G4H In a burglar alarm system, a plurality of transmitters are located in respective installations to be guarded and each is controlled by one or more respective burglary detection devices to transmit, using a common frequency, a coded signal representative of its respective installation, there being at least one continuously-operable control receiver comprising a substantially omni-directional aerial and a selective rotary aerial. Reception of such a coded signal at the central receiver through the omni-directional aerial gives an audio/visual alarm and the signal is recorded. To avoid conflict between different transmitters sending simultaneously, an operator at the central receiver can cause the circuits to be fed instead from the rotary aerial and the latter to be rotated through one (or two) revolutions, spikes being recorded on a chart recorder as the aerial aligns with the active transmitters, the directions of the transmitters being read by the operator from a scale alongside the chart. The operator then turns a knob to align the rotary aerial with the active transmitters in turn, using a selsyn, to enable the codes therefrom to be recorded. This alignment could alternatively be automatic.

Title: Sputter Resistive Cold Cathode for a Low Pressure Gas Discharge Device
IPC: H01J17/06
Filed: 1968-09-06
Abstract: 1,176,450. Lasers. R.C.A. CORPORATION. 6 Sept., 1968 [12 Sept., 1967], No. 42438/68. Heading H1C. Cathode sputtering in a cold cathode gas laser, e.g. helium-neon or argon, is minimized by embedding the cathode electrode in a porous mass of a sputter resistant insulator which is chemically inert to a given alkali metal, the mass having a substantial covering of the alkali metal which is adsorbed and transforms the insulator into an effective conductor. A constriction is provided in the gas passage between the cathode and the main portion of the discharge tube so that any alkali metal removed by evaporation eventually returns to the porous mass. A helium neon laser is shown in Fig. 1 and comprises a gas tube 100 terminated by Brewster windows 106, 108 and with pockets for an anode 116 and a cathode 112. The cathode comprises a helical tungsten electrode 124 embedded in an alumina porous insulator 126. A small amount of an alkali metal, such as potassium, is introduced into the cathode through a tube 130 which is afterwards sealed. The constriction for limiting the circulation of alkali metal is provided by a small opening 134 in a ceramic insert 132. Parallel external resonator mirrors are provided (not shown). A gas pressure considerably less than 10 Torr is used. In a modification, Fig. 2, a cold cathode 212 is located coaxially of the laser tube 200, the constriction being provided by a small opening 234 in a ceramic insert 232. A tungsten mesh electrode 224 is used which is embedded in a porous alumina layer 226. An alternative arrangement. Fig. 3, has a constriction provided by a small opening 334 in a ceramic insert 332, and an electrode formed of a plurality of tungsten wires 324 the ends of which extend to the surface of the surrounding alumina mass 326. The arrangement of Fig. 3 is stated to be particularly useful for pulsed argon lasers.

Filed: 1964-10-20
Abstract: 1,127,015. Associative stores. PLESSEYU.K. Ltd. 24 Sept., 1965 [20 Oct., 1964], No. 42778/64. Heading G4C. [Also in Division H3] In an associative store using a matrix of thin film magnetic storage elements arranged for non-destructive read-out, match and mismatch of a search word is indicated by the absence and presence respectively of output signals on the word conduotors, the word location being registered in a staticizer using biased magnetic thin film devices. The matrix store described, Fig. 4 (not shown), uses separate storage elements each consisting of a storage film 2 and a read-out film 1 of the kind described in Specification 1,109,169, Fig. 1 (not shown). Each digit conductor 6 of the matrix is connected to sources 8, 9 of positive and negative pulses representing the digits " 1 " and " 0 " respectively, non-destructive read-out of a search word being effected by selectively energizing one source for each digit conductor so as to make up the word required. Output signals are induced in each word conductor 7 where a digit mismatch occurs, and since each word conductor is connected to an input conductor 12 of a respective magnetic thin film device 10, Fig. 7, in the staticizer, only that film 10 connected to an unenergized word conductor is not switched. Each film has bias, sense and reset conductors 11, the bias being a D.C. current of such value as to be just insufficient to switch a film by itself. Subsequently to the non- destructive read-out operation, a pulse is applied to the reset conductor which switches the previously unswitched film, thereby producing a location-indicating output on the sense conductor. The thin films 10 may be arranged in matrix groups the co-ordinates of which are connected to a translator, Fig. 8 (not shown), using linear magnetic cores, the word address produced by the translator passing through read amplifiers to recall the remainder of the wanted word. For destructive read out purposes pulses are applied to the word conductors and the resulting flux changes detected on the digit conductors. For writing into the store coincident current pulses are applied to the digit and word conductors, the digit to be written being determined by the pulse polarity in the respective digit conductor. The thin magnetic films used may be planar or plated wire.

Title: Improvements in the production of aliphatic anhydrides and acids
IPC: C07C51/54
Filed: 1960-12-13
Abstract: Aliphatic C2-4 acids and C4-8 anhydrides are obtained by oxidising the corresponding aldehydes in a reaction bath containing a mixture of the acid, anhydride and an oxidation catalyst, the mixture of gases and vapours leaving the reaction bath being condensed in a dephlegmator in which the flow of coolant is so controlled that there is condensed and refluxed from the dephlegmator to the bath only the amount of liquid required to maintain the volume of the bath constant.  A distillation tower can be interposed between the bath and the dephlegmator, to the head of which is refluxed the condensate from the dephlegmator and the bottom product of which is refluxed to the bath, the tower being heated by merely using the reaction heat. The gas and vapour mixture leaving the dephlegmator is further cooled in a condenser to give a liquid mixture which is distilled to separate its constituents, whilst at least part of p  the residual gases are recycled to the bath after the addition of fresh free-oxygen containing gas.  Acetic acid and anhydride are produced from acetaldehyde in the examples.

Abstract: 1509399 Automatic exchange systems V R WISSING 21 Oct 1975 [23 Oct 1974] 43177/75 Heading H4K A party line/intercom system comprises a plurality of telephone sets connected in parallel to the same subscriber line connected via a connection unit to a public exchange, the connection unit and each telephone set having an associated signal detector adapted to respond to its own unique dialling signal transmittable by any of said telephone sets or said connection unit. The arrangement allows any two sets connected to the same line to communicate with each other without ringing any other set connected to that line. In the preferred form each set is equipped for pushbutton multi-frequency dialling and each code detector includes a resonant circuit fo tuned to the lower frequency of a one digit code. A transistor T conducts in response to this code causing a unijunction transistor UJT to produce pulses of a duration and separation defined by the values of resistor R and capacitor C. A tone ringer TR produces an acoustic signal. Instead of multifrequency dialling signals digital signalling (decimal, binary biquinary, hexadecimal etc.) may be employed. The code detectors may be connected to line via plug and socket connectors. The signal detector in the connection unit may be arranged to respond to a different type of signal, e.g. a line interruption or earth signal.
