Abstract: 374,126. Thermionic cathodes. FREEDMAN, P., 70, Durley Road, London. March 5, 1931, No. 6807. [Class 39 (i).] In an equipotential cathode having a resistance mounted on or embedded in a refractory insulating body such as magnesia, alumina or porcelain, deleterious effects of electrolytic action within the refractory body upon its resistance are minimized by means of a refractory conducting element or shield arranged in the region of the maximum electrolytic effect, and of such dimensions as not to cool the insulating material to such an extent as to displace the region of maximum electrolysis. The shields may consist of bands, discs or rods in contact with the resistance and the refractory body. They may be placed at the ends of the resistance, or preferably, as shown, bands 12 are arranged at points of the refractory body 7 near the ends of the resistance 6, and are connected with the ends. The shield is arranged so as not to short-circuit the resistance. The resistance may be of tungsten, or tungsten carbide orsilicide. In another heater a crinkled wire is mounted on a flat insulating plate by means of hooks or pins, and the shields consist of discs embedded in the plate. The cathode may be used in valves or in metallic vapour lamps as described in Specification 329,627, (Class 39 (i), Electric lamps, Arc &c.]. Specification 367,825 also is referred to.

Title: Telephone exchange circuitry
IPC: H04Q11/04
Filed: 1976-02-23
Abstract: 1533613 TDM exchanges THOMSON CSF 23 Feb 1976 [25 Feb 1975] 07121/76 Heading H4K A TDM exchange for interconnecting incoming and outgoing subscriber circuits CT includes a plurality of input concentration circuits C1-6 arranged in pairs, e.g. C1/C2, and a plurality of output deconcentration circuits D1-6 similarly arranged. Each input CT is connected to both elements of a concentrator pair, and output CT's are similarly related to deconcentrator pairs. A plurality of switching circuits, e.g. CTE2- CS2-CTS2, is provided. Each switching circuit is connected to two concentrators, each from a different pair-e.g. CTE2 connected to C2 and C3-and is similarly connected to two deconcentrators-e.g. CTS2 connected to D2 and D3. Concentration/deconcentration control units MAC/MAD are assigned to concentrators/deconcentrators in a manner corresponding to that of the switching element. The exchange preferably takes the sectionalized form shown, switching taking place on a T-S-T basis. Time switching is performed by 32-word memories CTE1-3 and CTS1-3, under control of 32-word address memories MAT1-3 and MAT4-6. The space switches CS1-3 are controlled by 32-word memories MAS1-3, which also allow inter-section switching along highways B1-3. Normally, speech communication through the exchange is via only the "main" concentrators C1, 3, 5 and deconcentrators D1, 3, 5. However, should one of the switching circuits, e.g. CTE1-CS1-CTS1, become faulty, central control can instruct MAC1, MAD1, MAC2 and MAD2 to "close" Cl and Dl and "open" C2 and D2, thereby directing traffic to the section B switching circuit and by-passing the faulty one. Similarly, an overload of traffic in one section, e.g. A, may be mitigated by "partially" closing C1 and Dl. This done by allowing Cl and Dl to deal only with a certain number of TDM channels, selected by central control via MAT1, 2 and MAD1, 2, and diverting the remainder through C2 to section B.

Abstract: Substituted vinylamines of the general formula <FORM:0917436/IV (b)/1> wherein A is a hydrogen atom or a methyl radical, B is a methyl, phenyl or chlorophenyl radical, X is a carbalkoxy, acyl or methyl group, Y is an alkoxy radical or is a methyl radical when X is a methyl and n is 0 or in the case where X and Y together denote C2H4, n is 1 or 2, are made by reacting a compound of the formula:- <FORM:0917436/IV (b)/2> wherein X, Y and n are as above, or a corresponding metal compound or Grignard compound thereof, with an amide chloride of the formula:-  <FORM:0917436/IV (b)/3> wherein A and B are as above and Z is Cl-or (PO2Cl2)-, the reaction being carried out in the presence of an acid-binding agent when the first reaction component is not used in the form of a metal compound or Grignard compound.  Where an acid-binding agent is used it may be an alkali metal or alkaline earth metal, a Friedel-Crafts catalyst, an organic base or an alkali metal or alkaline earth metal hydride, amide, carbonate, bicarbonate, hydroxide, alcoholate or salt of an organic acid.  The vinylamines in which Y is -OC2H5, n is 0 and X is methyl, acetyl or carbethoxy, are new.  Examples describe the preparation of dimethylaminomethylene-malonic acid diethyl ester; N - phenyl - N - methylaminomethylene-malonic acid diethyl ester; dimethyl-aminomethylene - acetoacetic acid ethyl ester; m - chlorophenylaminomethylene-malonic acid diethyl ester; dimethylaminomethylene-cyclohexanone; dimethylaminomethylene-cyclopentanone and dimethylaminomethylenemethyl ethyl ketone.
Patent GB-656262-A (GB)
Title: Interval timer
IPC: G04F3/02
Filed: 1948-03-08
Abstract: 656,262. Time switches. BROWN, F. H. March 8, 1948, No. 7150. Convention date, March 26, 1947. [Class 38(v)] [Also in Groups XVIII and XXXVIII] A timer which gives an alarm after the lapse of a selected time interval is adapted to be set, wound and started by a single manual control 16, to have variable ratio gearing 27, 28 giving the indicator an approximately logarithmic scale, and means to ensure that the alarm continues for a predetermined time after initiation. When functioning, the mainspring contained within the barrel 5 drives wheel 19 via arbor 2, ratchet wheel 17 and pawl 18, and this in turn drives the time train culminating in the escapement 44, 45 and balance wheel 47. The main shaft 15 is thereby rotated clockwise at a uniform speed by clutch member 23 so that the pinion 14 drives the indicator pointer 29 through wheel 24 and spiral gears 27, 28, the latter of which is freely carried on shaft 15. When the pointer reaches zero on the scale 31 the pin 69 on wheel 24 moves lever 68 against stop 72 so that the ratchet leaf 74 releases a pin 65 to allow wheel 57 to be driven by the mainspring barrel until a further pin 65 is stopped by leaf 75 as illustrated in Fig. 4 (not shown). The speed of rotation of wheel 57 is controlled by the alarm escapement 61, 62 which oscillates a hammer 64 to ring a bell (not shown). Alternatively a valve, switch, or other mechanism may be actuated. As a pin 65 approaches the ratchet leaf 75 to stop the alarm action another pin 65 rides on to the cam-shaped end 76 of lever 77 and thereby presses the resilient finger 79 against the serrated edge of the balance wheel 47 and stops the timing mechanism. The mainspring is wound by the action of turning knob 16 anticlockwise to set the pointer at the desired time interval, when pinion 14 drives wheel 9 at a lower ratio than that between 22 and 19 so that the spring is wound more than required to operate the timing mechanism for the desired period, thereby ensuring that power will be available to operate the alarm train. A slipping member within the barrel 5 prevents overwinding of the spring and allows the indicator to be set even when the spring is fully wound, and the clutch member 23 prevents strain on the time train. In the initial movement of the setting operation the pin 69 moves away from lever 68 and allows the pin 65 previously stopped by ratchet leaf 75 to move a short distance to leaf 74 as in Fig. 3 (not shown), and this slight rotation of wheel 57 causes the pin 65 pressing on end 76 of lever 77 to move away and allow the spring 81 to snap lever 77 back. This causes the resilient finger 79 to be swung away from the balance wheel in an approximately tangential direction and starts the wheel oscillating to set the time train in motion. Preferably the main shaft 15 rotates at one revolution per hour and the gearing is such that pointer 29 indicates up to 3 hours in somewhat less than one revolution so that the ends of the annular scale 31 do not coincide or overlap.

A viscosity meter, Fig. 1, comprises a measuring body 3 for dipping into a fluid to be tested, the measuring body 3 being mounted on the rotor shaft 2 of a synchronous electric motor whose stator 1 is supported by a shaft 4 coaxial with the rotor shaft 2 in a manner permitting the stator 1 to turn easily in an outer casing 10 against the force of a spring 13, this rotary deflection being a measure of the viscosity of the fluid under test and being indicated by a pointer 12, attached to the stator 1, moving over a scale 11. The measuring body 3 maybe surrounded by a tube 18 adapted to be slipped on to the casing 10 and having an aperture 17 in it serving as a mark for indicating the correct depth to which the meter should be lowered in the fluid to be tested. Alternatively, Fig. 2, the shaft 2 may be surrounded by a tube 21 removably attached to the casing 10, the tube 21 being capable of being placed on a separate measuring vessel 20 so that the measuring body 3 is correctly immersed in fluid contained therein, the amount of fluid being fixed by an overflow 22.

Abstract: 163,173. Evans, J. G. P. March 9, 1920. Hydrocarbons, distilling; progressive evaporators; evaporators and condensers in structural combination.-Oil and like liquids are distilled by passage through zones of successively increasing temperatures, a series of distillates being obtained by condensing the vapours from each zone within the still. Condensation is effected by mixing the vapours from successive zones. The oil entering the still 10 by a pipe 15 flows through compartments formed by partitions 14. The last compartment is heated by a furnace 22, the remainder of the still being encased in an insulating-jacket 13. The condenser consists of a V-shaped trough 19 also divided by the partition 14, each compartment receiving vapours from both the distilling-compartment below and the hotter one of the adjacent condensing-compartments. The condensates are led by pipes 21 through the cooler distilling-compartments, which are in this way heated. The heat of the residue is also recovered by leading the residue pipe 17 through the oil in the still.

Abstract: 376,741. Copying records. DIEUX, J., 2, Quai des Celestine, Paris. March 9, 1931, No. 7238. Convention date, May 22, 1930. [Class 40 (ii).] Audio currents from a source N1 give rise in a double-anode valve L1 to two outputs m1, m2 on which are superposed symmetrical disturbing currents, e.g. from an alternating- current source S1 and rectifiers or commutators D1, D2. The outputs m1 m2 may be recorded on separate gramophone discs, from which reproduction currents are taken simultaneously and re-combined by a double-grid valve L2 after the disturbances introduced from S1, D1, D2 have been annulled by counter-disturbances from S<1>1, D<1>1' D<1>2. Apart from ensuring secrecy the invention is stated to reduce parasitic noises. The Specification as open to inspection under Sect. 91 (3) (a) describes also the production of two records by separate microphones and amplifiers having different frequency characteristics, the currents picked up from the two records being then amplified and combined to act on a single recorder to produce a master record.

Patent GB-540616-A (GB)
Title: Fuel injection apparatus
IPC: F02M59/26
Filed: 1940-04-22
Abstract: 540,616. Fuel injection pumps. BENDIX AVIATION CORPORATION. April 22, 1940, No. 7244. Convention date, May 2, 1939. [Class 102 (i)] In a fuel injection pump the cylinder 7 is formed with one or more relatively small pressure relief ports 52 in constant communication with the supply passage 44 or other lowpressure chamber outside the cylinder, the ports 52 being circumferentially spaced from, and preferably diametrically opposite, inlet and byepass ports 11, 12. The ports 52 tend to balance the pressure on the two sides of the plunger 13 and reduce wear adjacent the ports 11, 12. Lubrication, and additional pressure balancing, may be effected by means of a helical groove 17 in the plunger diametrically opposite, and somewhat smaller than, the helical metering groove 16. To prevent erosion at the ports 11, 12, the pump casing 5 may be fitted with a stainless steel insert 41 which is channel-shaped in radial cross-section and formed on one side with grooves 47, 48 in communication with the fuel supply passage 44. The insert 41 may be fitted with a hardened steel plug 50 opposite the byepass port 12. The plug 50 and another plug 51 serve to vent the pump when it is in a horizontal or vertical position respectively. The end of the pressure chamber is formed by an adaptor 30 having a differential cylindrical passage containing a delivery valve 31. The latter comprises a tapered head part 38, a grooved central part 36, and an upper piston part 37 ; it is controlled by a spring 39 surrounding a tubular stop member 40. After the valve 31 has been closed, its continued downward movement in the adaptor 30 obviates any dribbling of fuel at the nozzle. Any air that accumulates in the pressure chamber is trapped in the grooves in the central part 36 when the valve 31 snaps back on to its seat. This is repeated until the air is compressed sufficiently to open valve 31 and move the part 37 out of the adaptor 30, thereby automatically preventing the pump becoming airbound.
