Title: Improvements in timers or cut-outs
Inventor: POWELL ANTHONY
IPC: H01H43/30
Filed: 1960-02-12
Abstract: 981,751. Thermal switches; cam-operated switches; two-part couplings combined with switches. SEEMARK SWITCHES Ltd. Feb. 13, 1961 [Feb. 12, 1960], No. 5069/60. Headings H2B and H2E A timer comprises a heat-sensitive element, heating means therefor and cycle-control means associated therewith in controlling relation thereto and operable by thermal movements of said element, in combination with main controloperating means including a spring-driven stepwise moving member co-operating with a detent connected with the heat-sensitive element so as to move step by step as successive thermal movements are performed by the element, thereby to operate a main control after a predetermined number of steps. In the form shown, the heat-sensitive element consists of an adjustably mounted bi-metal strip 36 which when cold holds closed contacts on a pair of strips 46, 47 so as to energize heaters 45 for the bi-metal. As this is heated its centre rises (out of the Figure) and allows the contacts to open to de-energize the bi-metal which thus re-cools, and this cycling continues until a main switch (Fig. 5, not shown) is opened. The main switch is controlled by a cam attached to a toothed wheel 42 which is biased by a spring which is energized by depressing a button 13 to rotate a segment 67 and meshing pinion 66. As the bimetal is heated and cooled, detents 40, 41 thereon allow step by step movement of the wheel 42 until the main switch is opened. The main switch may be opened manually at any time by depressing a further button 14 which is then latched by a bar 98 until freed by depression of button 13. The timer may be incorporated in a wall socket or a plug.

Title: Method and apparatus for control of polymerization reactions
Inventor: HENDERSON WILLIAM BRUCE
IPC: C08F2/00
Filed: 1958-02-17
Abstract: A method of polymerizing unsaturated hydrocarbons in which the hydrocarbon is contacted with a catalyst in a reaction zone and a coolant is passed in indirect heat exchange with the reaction mixture in the zone comprises measuring the volume or flow rate of coolant vapours evaporated as a result of the indirect heat exchange and adjusting the rate of introduction of catalyst or hydrocarbon into the reaction zone so as to maintain a predetermined coolant evaporation rate and recovering an efficient stress containing polymer.  Specified hydrocarbons are ethylene, propylene, isobutene, butadiene and styrene alone or in admixture with one another.  The preferred catalyst is chromium oxide associated with at least one of the amides of silica, alumina, zirconia, and thoria.  The coolant is preferably circulated in indirect heat exchange at a constant rate and under constant pressure, preferably being at boiling temperature when passed into the indirect heat exchange.  Apparatus for carrying out the process is described.  Specifications 790,195 and 804,641 are referred to.

Title: Improvements in or relating to ionisation gauges
IPC: G01L21/00
Filed: 1952-02-29
Abstract: 691,730. Ionization gauges. MULLARD RADIO VALVE CO., Ltd. Feb. 29, 1962, No. 5377/52. Class 37. In a vacuum gauge of the ionization type in which a triode structure is open to-the vacuum to be measured and in which the grid is positive and the anode negative with respect to the filament, the filament current is controlled by a saturable reactor. The ionization gauge valve 1 comprises a filament 5, positive electrode 6, and negative electrode 6a. The filament 5 is connected in series with the secondary winding 7 of a transformer 8 and the controlled windings 10, 11 of a saturable reactor 12 through rectifiers 13, 14. A resistor 24 is connected between the junction of -the windings 10, 11 and the junction of the rectifiers 13, 14. The controlling windings 15, 16 of the saturable reactor 12 are connected in series between the anodes of a double triode valve 17, the cathodes of which are earthed through a bias resistor 18. The control grid 19 of one of the triode sections is connected to a stabilized voltage source, which is manually variable. The control grid 20 of the other section is connected ,to earth through a tgrid-leak 21 and to the junction of a pair of resistors 22, 23 connected across the filament 5. If the current between the filament 5 and electrode 6 of the valve 1 .alters, the potential of the control grid 20 also alters and causes a change in the current ,through the control windings 15, 16 so as to adjust the filament current to the correct value. This value of filament current to give a predetermined current in the valve 1 may also be obtained by manually adjusting the voltage on the grid 19 so as to set the equilibrium point of the system.

Title: Improvements in or relating to cigar banding machines
IPC: A24D1/16
Filed: 1930-02-18
Abstract: <PICT:0349123/III/1> In a cigar-banding machine the gumming or moistening device consists of a strip with continuous, step-by-step operation which passes over a brush mounted in a reservoir, the moistened strip being brought into contact with the end of the cigar band, a throw-out mechanism being provided which is operated in the absence of a band.  The liquid container 264 is given a horizontal reciprocatory movement by means of a lever 276, and a lifting movement by means of a lever 301.  The continuous strip 263 is led from a supply reel across the top of the container where it is moistened by a brush 265, and is then returned along a fixed guide 284, and runs to a waste receptacle.  The strip is fed by being gripped during the forward movement of the container, the gripping means comprising a hardened plate 290 and a bevelled edge 289 mounted on a pivoted member 288, a tension weight 283 riding in slots 282 resting on the top of the strip.  The member 288 is operated by a rod 293 the upper end of which engages in an adjustable socket in the lever 288.  By adjusting the socket, the period during which the edge 289 is operative can be varied, thus varying the feed of the strip. On the upward swing of the container the looped end of the strip is brought into contact with the end of the band 71 which is supported by the end 69 of a spring-influenced rocker arm 312, the other end of which is engaged by an angular member 314 on the pivoted clamping member 288; by these means the arm 312 is raised during the feeding movement of the strip, as shown, and is lowered to operative position against a stop 316.  In the event of a band not being present the vacuum in the separator 121 is broken and a stop is operated to prevent the lowering of the arm 312, thus preventing the gumming of the support 69.

Title: Improvements in or relating to devices for indicating the presence of a particular pulse group having preselected time intervals between the pulses thereof
IPC: H04Q1/40
Filed: 1955-02-23
Abstract: 769,125. Pulse selecting circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 23, 1955 [Feb. 26, 1954], No. 5488/55. Class 40(6) In a circuit for indicating the presence in a pulse train of a particular group of pulses having predetermined time intervals between them, the pulses are applied to a delay network from the tapping points of which connections are made to a cascaded connection of electric discharge tubes so that only when the required pulse group is applied are all the tubes simultaneously actuated to pass an output pulse and thus give an indication of the required pulse group. Fig. 1a shows a pulse train in which it is required to indicate the presence of the three pulses 1, 2 and 3 in the first group of the train. These are applied as shown in Fig. 2 to the input terminals of a terminated delay network 6, the tapping poirits 7, 11 and 10 of which are such that the delay between 7 and 11 and between 11 and 10 respectively are equal to the intervals between pulses 1 and 2 and 2 and 3 respectively. The discharge tubes 12, 13 and 14 are normally biased to be non-conductive. It will be seen from Fig. 1b and c that only during the occurrence of the pulse 3 of the required group are all the tubes 12, 13 and 14 simultaneously conductive so that a pulse from generator 32 will pass to the output 30. In a modification shown in Fig. 3 the tubes are replaced by biased semiconductor diodes 37. 41 which are normally conductive and thus normally form with resistors 34 and 38 an impedance network between the input terminals 7, 8 and the output 30 which has a very high attenuation. When the required pulse group is present at the input 7, 8 of the delay line 6 the diodes 37, 41 are rendered non-conductive and an output signal appears at terminal 30.
