Title: Electronic Circuit Arrangement for Increasing Contour Sharpness of a Television Picture
Inventor: LEGLER ERNEST
IPC: H04N5/208
Filed: 1968-07-18
Abstract: 1,197,097. Television. FERNSEH G.m.b.H. 18 July, 1968 [28 July, 1967], No. 34276/68. Heading H4F. A complex control signal for producing both vertical and horizontal aperture correction of a T.V. signal, particularly a colour signal having an independent luminance component, is obtained by combining separately produced vertical and horizontal aperture correction control signals and adding them to the T.V. signal. The vertical control signal is obtained by applying the T.V. signal to two successive 1-line delay devices 11, 12, adding the resulting signal to the original T.V. signal in an adder 15, inverting the phase of the sum and halving its amplitude in a phase inverter 16, and adding the resulting signal in an adder 17 to the 1-line delayed output from the delay device 11. Preferably low pass filters 13, 14, 18 are provided as shown before each adder. The horizontal control signal is obtained by inverting the phase of the 1-line delayed band width reduced output from the filter 18 in an inverter 19 and adding it an adder 20 to the output from the 1-line delay device 11 after compensation at 21 for the delay produced by the inverter 19. Both control signals are amplified by independently controlled amplifiers 22, 23 prior to their combination in an adder 24. A limiter device 25 may suppress the small amplitude noise component of the complex control signal before it is added to the 1-line delayed full band-width T.V. signal in an adder 26. The delay devices 11, 12 preferably comprise quartz ultrasonic delay lines, the T.V. signal being modulated on to a carrier wave prior to its arrival at each delay line and subsequently demodulated.

Abstract: 926,787. Deriving pressure by temperature effect. BENDIX CORPORATION. Sept. 25, 1961 [Oct. 3, 1960], No. 34309/61. Class 106 (2). The partial pressure of oxygen in the air-supply of air- or spacecraft is measured by mixing it in a pressure-sensing device 10 supplied with a combustible gas such as hydrogen from a supply 11, and using the heat of the hydrogenoxygen reaction to expand gas in a bellows 14 the mechanical movement of which will thus be a function of the partial pressure of oxygen in the system. Movement of the bellows may be used for controlling the oxygen flow. Air reaches chamber 26 through filters 28 and together with hydrogen entering via inlet 18 and the adjustable jet nozzle 27, passes through the Venturi opening 32 to a diffuser 35 and then to a palladium screen 36 which acts as catalyst. The reaction heat reaches the fluid-filled line 42 supplying bellows 14 through a heatexchanging matrix 41. Alternatively, a thermocouple may be employed. The apparatus may be exposed to ambient atmosphere and the partial pressure measurement used to derive altitude.

Title: Improvements in mercury vapour ejector pumps for high vacua
IPC: F04F9/00
Filed: 1921-12-22
Abstract: 174,054. Akt.-Ges. Brown, Boveri, et Cie. Jan. 8, 1921, [Convention date]. Addition to 165,400. Aspirating - apparatus, ejector.-Relates to mercury-vapour ejecting-apparatus for the production of high vacua, and consists in forming the air-inlet aperture in the straight vertical tube of the ejector of the parent invention with a lesser extent in the direction of the upward flow of the mercury vapour than transversely thereto, and also in so shaping the airinlet tube, which approximates to a U-shaped curvature at its lower end, that no part of the expanding mercury vapour can obtain unobstructed entry to the descending part of the tube. The heating-device F may be electric, the mercury vapour rising from the heating-chamber H into the vertical unobstructed ejector tube P, from the upper end of which leads the pipe V to the preliminary vacuum pump. Connection with the chamber to be exhausted is made by a pipe R, whence descends the admission pipe P to a bend C from which it passes upwards into the ejector tube by a rectangular aperture O of greater width than depth. The cooling-water jacket W surrounds both the air admission and ejector tubes, but is not carried downwards sufficiently far to cool the heating-chamber and thereby cause premature condensation of mercury vapour.

Title: Device for developing neutralizing signals for an echo suppressor
IPC: H04B3/20
Filed: 1974-08-06
Abstract: 1445773 Data transmission systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 6 Aug 1974 [8 Aug 1973] 34629/74 Heading H4P In a device for developing a neutralization signal for an echo suppressor, necessary for the transmission of data on a telephone line having four wires, in which each transmission of data is preceded by an identification signal at a given frequency, a counter at 17, Fig. 1, produces a first neutralization condition N1 when there is at least one change in sign of a signal on the line in a predetermined period, a counter at 16 counts the changes in sign of the line signal during a second predetermined period and produces a second neutralization condition N2 when the state of the counter at 16 is between two predetermined limits and a circuit 18 combines the two conditions N1, N2. The circuit 18 includes a shift register (41-44, Fig. 7, not shown) which triggers a bi-stable flip-flop 19 to provide a neutralizing signal at 22 only when the neutralization conditions N1 and N2 are combined a predetermined number of times in succession and the line signal level is greater than a given value. The output of a circuit 15, disclosed in detail (Fig. 4, not shown) provides a binary signal at its output CS at sampling instants determined by clock pulses H2 when the line signal changes sign only when the amplitude of the signal exceeds - 46 dBmo. The circuit 17 includes a shift register (34, 36, Fig. 6, not shown) and checks that the change of sign signal CS is applied at least once every three sampling instants to provide the neutralization condition N1. The circuit 16 includes a counter (29, Fig. 5, not shown) and provides the neutralization condition N2 from the output of a flip-flop (33) when during a 50 ms. period the number of changes in sign is between 208 and 212. An AND gate (31) provides a signal to the flip-flop (33) when the count of the counter (29) is 250 corresponding to 208 changes of sign. The output from a further AND gate (32) provide a signal to the flip-flop (33) when the count of the counter (29) is 255 corresponding to 213 changes in sign. Clock signals H1 and H3 obtained from a counter 21 are applied to a gate (30) which resets the counter (29) to a count of 42. A monostable element 20 whose unstable time corresponds to a holding time is triggered by outputs of a A/D converter 13 corresponding to a level of the line signal below -34 dBmo. The output from the monostable element 20 resets the flip-flop 19 to the rest position. Output 22 is connected to the neutralization input of an echo suppressor. A test sequence generator 48 may be connected via switch 49 and A/D converter 13 to check the operation of the neutralization signal device.

Filed: 1934-12-04
Abstract: 443,512. Regulating delivery of pumps. MORRELL, J. J., and HENSHALL, A., 79, Byron Avenue, New Malden, Surrey. Dec. 4, 1934, No. 34868. [Class 102 (i)] In a pump of the type in which a piston c reciprocates in a box b, which reciprocates in an outer casing a, the output is varied by varying the effective area or the effective stroke of the pistons. As shown, the piston c, reciprocated by an eccentric d, is bored transversely to receive two plungers e which are frictionally held by springs or otherwise. Normally the plungers e move with the piston c, but the movement may be arrested by means of adjustable studs f, thus reducing the discharge of the piston c. Alternatively the working surface of the piston c or of the box b may be formed by a spring pressed plate, the movement of which can be arrested by means of stops. In a modification the yielding surface is interposed between the piston c and the box b.

Filed: 1927-12-23
Abstract: 307,563. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Dec. 23, 1927. Production of metal. - A process for making glass, particularly glass having a low coefficient of expansion, consists in uniting the mixed batch to form a coherent body, and then melting the body so formed. In an example given in the Specification, a batch for a glass containing 85 per cent of silica is finely divided and thoroughly mixed, and a quantity of the batch is pressed to form small rods, a pressure of 1000 kilogrammes per square centimetre being used. The rods are then sintered by heating them to a temperature of 900‹ C. or higher, producing bodies which can be directly heated in a flame, without the use of a pot, to melt and form glass. Either the pressing or the sintering process may be dispensed with; for example, the batch can be mixed, before pressing, with a binding agent. Alternatively, a coherent body can be obtained by sintering a quantity of batch in a boat-shaped mould.

IPC: B23K9/20
Filed: 1959-10-15
Abstract: 968,373. Welding by pressure. BIRWELCO Ltd. Jan. 16, 1961 [Oct. 15, 1959], No. 34930/59. Heading B3R. Apparatus for feeding metal studs and ferrules for surrounding the ends of the studs during welding to a welding position, in apparatus for welding studs one at a time to the exterior of a cylindrical workpiece, comprises means for feeding ferrules in a single file along a track, a stop for positioning the leading ferrule with its axis vertical, means for feeding studs in a single file to a position above that occupied by the leading ferrule when so positioned and means for releasing the leading stud in timed relation to the ferrule movement and the operations of the welding apparatus to permit it to fall to a position in which the lower end of the stud enters the ferrule. A tube 4, e.g. for a heat exchanger, is supported at one end by a wheeled carriage 7 on a track 6 and at the other end by adjustable rollers 9. The tube passes through gripping members 10 carried on pivoted members 13 coupled to a piston-and-cylinder device 14 to move the members 10 together or apart, the gripping means being rockable by a piston and cylinder device 15 and associated with a fixed abutment to cause the tube to be axially fed when rotated, as described in Specification 847,692. A second similar, but not turnable, gripping means 17 is provided. Devices 18, 22 for feeding ferrules and studs are mounted on a table 27 above the welding head 3, the devices being vibratable drums which feed the ferrules side-by-side along a track 19 to be discharged against a stop 25 and the studs endto-end to a flexible pipe 21 terminating in the head 3. The studs are received in a member 26 in which the leading stud is clamped during welding by a plunger 28 connected to one side of the welding current supply, the other side being connected to a plunger operated tube contact 54. The member 26 is open to allow the stud to move away therefrom when the tube is rotated. In operation after the leading stud has been welded to the tube, the tube is turned and moved axially and the stud moves out of the member 26. The plunger 28 is moved to a clamping position to arrest the movement of the next stud, the next ferrule moves to its welding position and the plunger is retracted to allow the stud to fall into the ferrule. The member 26 is raised by a fluid-operated device 34, the stud is clamped and then the device 34 is released. The arc welding of the stud, whose end may be aluminium coated, is then effected. As the tube is rotated the ferrules fall away from the studs but a roller 39, which may cause the axial feeding of the tube as set out in Specification 968,374 may crush the ferrules. The ferrules and studs may be brought together at a position removed from the welding head and a piston-operated pusher may move the assemblies one by one to the welding position.

Filed: 1971-07-26
Abstract: 1308872 Electro-medical apparatus L H KROHN 26 July 1971 [15 Sept 1970] 34974/71 Heading G1V [Also in Division G4] The outputs from a plurality of electrodes connected around a organ of the human body, Fig. 1 (not shown), are fed via a multiplexer to an analogue/digital converter, the converter output being recorded. The recorded outputs may be read out to a computer to derive a current density diagram. As described, Figs.6, 7, analogue signals from electrodes around the heart are fed on leads 113 via a switch 112 to an amplifier utilizing a base voltage derived from a selected three of the electrodes. After amplification the signals are fed via multiplexer 124 controlled by a counter 126 to the analogue/digital converter 132. After every fifteen digitisations a negative saturate byte is generated (to facilitate demultiplexing) under the control of counter 126. The digitized signals and negative saturate byte are fed via a switch 140 also receiving a positive saturate byte (for patient identification purposes) to tape recorder 146. The recorded signals may be fed to a computer (not described) to derive current density diagrams, the computer having been pre-set with data relating to the positions of the elecrode and the resistivity between the electrodes and the heart and they may be converted to analogue form and displayed. To read out recorded information relating to a particular patient the tape is rewound and counter 126 set to zero. The number corresponding to the patient is then entered using keyboard 176 and as the tape is driven positive saturate bytes step the counter 126. At equality of the count and patient number the tape drive is stopped. The data is read out via a digital/analogue converter 154 to sample and hold circuits 156, 158 (enabled by the decoder, which steps through sixteen addresses and is reset to its start position whenever a negative saturation byte is detected or it is at its sixteenth count) for display on an oscilloscope or pen recorder. Some of the electrode outputs may be read out via switch 112 to a conventional electrocardiographic system. The various operations of the digitized, recording and read out apparatus are controlled by a programmer 128. The connections on the leads on the patient may be examined by an operator touching them when the programmer closes a switch (212), Fig. 8, (not shown), to enable a vibrator (182) to step counter (126) slowly to sequentially display on an oscilloscope (214) each signal.

Abstract: 304,648. Schmidt, F. Jan. 23, 1928, [Convention date]. Phenol-aldehyde condensation products.-Condensation products of phenols and aldehydes, which are still liquid while hot, are hardened by treatment with as small quantities as possible of acid or acid-acting substances, i.e. substances which split off acids on dissociation, e.g. ethylene. chlorhydrin, magnesium chloride, and so that all particles continuously renew contact with each other and a thorough exchange of heat throughout the mass is obtained. The process may be carried out in a kneading apparatus, to effect the polymerization and further dehydration in a uniform manner. The mass becomes viscous and plastic, distinguished by lack of adhesiveness, and may be further treated by grinding or pressing &c., to obtain moulded articles.
