Title: Improvements in radio-receiving circuits employing band-pass filters
IPC: H03H7/01
Filed: 1937-06-26
Abstract: 485,713. Valve circuits; impedance networks. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 26, 1937, No. 17872. Convention date, June 29, 1936. [Classes 40 (iii) and 40 (v)] In amplifiers, particularly for the intermediate frequency of radio receivers, in which a hypercritically coupled band-pass filter II, whose band-width is varied by varying the coupling between the inductances 10, is used in conjunction with a subcritically coupled filter I or with a simple tuned circuit, the centre frequency of the filter II becomes displaced when the band-width is varied, so that the overall response curve becomes asymmetrical. According to the invention, the controls 21, 22 by which the band-width is varied are coupled with means 23, 24 for detuning the coupled circuits II. As the band-width increases the natural frequency of the coupled circuits thus decreases, and the pass band is correctly centred either throughout the range of adjustment or at the maximum band-width. This result may be effected by means of condensers 5, 6, shunted upon the ordinary tuning- condensers 3, 4, Fig. 1, or one auxiliary condenser may be used, or a condenser may be shunted across the magnetic coupling 10, Fig. 2 (not shown), or condenser plates 19, 20, Fig. 3, may be fixed to the ends of the coils 10, so that the reactance of the condenser 19, 20, is automatically varied as the magnetic coupling of the coils 10 is varied by their relative movement.

Abstract: 1,269,681. Bidirectional thyristor firing circuits. E. W. BLISS CO. 8 April, 1969 [16 April, 1968], No. 17962/69. Heading H3T. [Also in Division H2] A triac 40 or like monolithic A.C. switching device is fixed via a transformer 22 by pulses of frequency high relative to the A.C. supply, derived from a feedback type oscillator 10, the conventional gate current limiting resistor being omitted from the secondary circuit of the transformer. False firing due to increased leakage current at high temperatures may thus be reduced. As described the pulses are generated by a saturating transformer type blocking oscillator having a frequency controlling timing circuit 11, 21. The oscillator periodically discharges a capacitor 30 through the transformer primary winding to produce a short steep firing pulse. Resistor 32 limits the average firing current after the first few pulses and the effects of omitting the capacitor and resistor are described.

Title: Improvements relating to tyre retreading moulds
Inventor: GLYNN EDWIN ALLEN
IPC: B29D30/54
Filed: 1951-08-01
Abstract: 690,081. Tyre-retreading moulds. SUPER MOLD CORPORATION. Aug. 1, 1951, No. 18236/51. Class 87 (ii).  Relates to the retreading of vehicle tyres and consists in a tread centring mechanism for a tyre mould including an annular body having a matrix therein in which a pair of axially spaced but aligned tyre bead engaging rings are disposed in the mould concentrically therewith and radially inwards of the matrix, being so mounted as to be radially fixed but axially movable relatively to the body, yieldable means being provided for resisting axial outward movement of the rings. The tyre bead engaging rims 14 are held in position by circumferentially spaced pins 16 which are centred in sockets 18 formed in long bosses 17 projecting from annular mounting plates 8. The ring 14, which may have more than one seat 15 for the tyre bead, are pressed inwards by springs 19 to an extent limited by nuts 20 on the pins 16. The device is attached to the mould by circumferentially spaced clips, one of which is shown in Fig. 3, the mounting plates 8 having grooves 9 which fit flanges 6 on the skirts 5 of the annular mould halves 2. The mould halves, which have steam chambers 4, inclose matrix halves 3 and are brought together by power operated means, not shown. When the tyre to be retreaded has been placed in the mould the halves are closed and the tyre beads thus pressed towards one another by the rims 15. This movement of the tyre beads has the effect of seating the tyre in the mould so that the new tread material is properly centred. When the tyre is inflated the beads are able to move apart because of the resilience of the springs 19, the rims 14 maintaining the beads in alignment and so ensuring that the new tread remains properly centred. The same tread centring mechanism can be applied to different moulds.

Title: Apparatus for detecting corrugation of strip material
IPC: G01B11/245
Filed: 1971-06-01
Abstract: 1386603 Photoelectric measurement of waviness of strip material BRITISH NON-FERROUS METALS RESEARCH ASSOCIATION 30 May 1972 [1 June 1971] 18281/71 Heading G1A Waviness of strip material is measured by detecting photo-electrically deviations in the direction of light reflected from the strip as it is moved relative to the detection apparatus. In the arrangement of Fig.1, light from lamp 10 is collimated by lens 11 and formed into a line image by cylindrical or other astigmatic lens 12 for passage through slit 13 between two photo-cells 17. Wide angle collimator 14 provides illumination of a portion of the strip 15 width with a narrow line or an elongated or rectangular/square spot. When the strip is completely flat, the reflected light is returned to a focus at slit 13. When the strip is deformed reflected light is deviated to one or other of photo-cells 17 which are arranged behind masks 16 of the form shown in Fig.2. These are designed with apertures of parabolic triangular form so that the transmission of a mask is proportional to the square of the distance from the slit, i.e. proportional to #<SP>2</SP>, where # is the angle of tilt of the portion of the strip under examination at that instant. The photo-cell 17 outputs are fed to operational amplifiers 31, 32 and added in further operational amplifier 36. In order to obtain a measure of waviness through the length of the strip, the signal is integrated over the time that the strip is monitored in integrator 42 whose output is supplied to sample-hold circuit 43 and display 44. In order to compensate for variations in the reflectivity of the strip 15, a further pan of photo-cells 22 are provided, sensing reflected light via beam splitter 18  and a mask arrangement of the same form as the marginal portions of the masks 16. The outputs of cells 22 are added in operational amplifier 37 and applied to divider 41 where the cells 17 signal is divided by the reflectivity signal. Further compensation, this time for variations in light source intensity is provided by cells 20 which provides compensation via operational amplifier 35 and potentiometers 38, 39. To reduce scattered light, perforated screens 19, 21 are provided. Alternative arrangements. Instead of using square law masks in the Fig. 1 arrangement squaring circuits may be used. The greater signal from amplifier 31 or 32 only may be used. Deflection may be monitored by a row of photo-cells associated with a row of corresponding light guides, the cell having maximum illumination indicating the angular deviation of the strip portion. Other arrangements using light guides are possible. Instead of measuring the integral of the square of the deflection, simply the maximum deflection may be measured or the difference in deflection at different positions across the strip width. A plurality of detector arrangements may be used to provide an alarm or rejection signal and their outputs combined in a number of ways e.g. by subtracting the minimum output value from the others. Signals may be recorded.

Title: Process for the preparation of polyfunctional aliphatic isocyanates
IPC: C08G18/75
Filed: 1966-04-27
Abstract: Polyfunctional aliphatic isocyanates are obtained by reacting sodium azide with acid chlorides of polymerized fatty acids in the presence of 0.1 to 50% by volume, based on the acid chloride, of an N,N-dialkyl-substituted acid amide of an aliphatic monocarboxylic acid containing 1 to 4 carbon atoms and in the absence of moisture. The process is generally effected at 40-200 DEG  C. and a further inert diluent may be added.  The preferred monocarboxylic acid amide is dimethylformamide and the carboxylic acid chlorides are suitably those obtained by chlorination of polymerized fatty acids (generally of average molecular weight 400-800) which are derived from C16- 22 natural unsaturated fatty acids.  The products generally have an average content of 32 carbon atoms per molecule.  Examples are given in which the polymerized fatty acid is derived from cottonseed olein. Reference has been directed by the Comptroller to Specification 1,023,390.

[Class 114] A screw propeller wherein the blades are turned about their axes to vary the pitch is provided with means which are a function of the engine speed and which tend to turn the blades against the action of a resisting means such as a spring, these two controls being interconnected so that the resultant moment acting to turn the blades from one set position to another increases as soon as the resultant is sufficient to initiate the movement of the blades, the latter being then definitely moved from one set position to another. A weight 5 is coupled by an arm 4 to the blade 1 and by centrifugal force tends to move this blade. It is connected by a link 7 to a member 9 under spring control 12 in such a manner that when the centrifugal force is sufficient to overcome the spring the blade is moved and the resisting moment diminishes. The member 9 has two collars 10, 11, which contact with stops to determine the high and low pitch positions. The stop positions may be adjustable as by the movement of the block 13 which is screwed into the engine case. The block 13 may be adjusted by hand or it may have a weighted arm 81 whereby centrifugal force acting against a spring automatically sets the stop position. In one form the connection of the mechanism with the blade is by means of an arm 17 secured to a ring 16 that is attached to a block 14 embracing the blade root. The end positions of the stops may be adjusted from the cockpit of the aeroplane or may be modified automatically in accordance with the variation in pressure due to change of altitude. In a modification the mechanism provides for three stop positions and for this purpose in addition to the main spring a second spring is provided which comes into operation after a predetermined action of the first spring.

Filed: 1946-06-20
Abstract: 613,403. Erecting multi-storied houses. LINDNER, H. June 20, 1946, No. 18578. ,[Class 20(i)] Multi-storied houses are erected by connecting together the different sections, e.g. roof and floor sections or wall and floor sections which pertain to the same storey, to form a unit which is lifted through a height corresponding to the height of the storey to make room for the assembly of sections pertaining to the next storey on the same level as the preceding one. Supports 3 on a firm foundation 2 carry a housing 4 for an elevating screw 7 which is driven through double worm gearing 9, 8 by an electric motor 11. The screws 7 are located at points where it is intended that columns shall exist in the completed building and elsewhere as necessary and pass through a ground floor 5. The roof 12 having bosses 13 to receive the upper ends of the screws 7 are elevated through one storey height and a metal casing 14, Fig. 4, which may be in two parts is applied between the roof 12 and the ground floor 5 so as to surround each screw, which is then withdrawn. Members 15 passed through slots in the casings 14 form supports for floor members 16 and the storey is completed by walls 17 provided with all required fittings such as radiators 19. The completed storey is then elevated through storey height by the screws 7 which bear on the cross members 15 whereupon further casings 20, Fig. 6, of slightly larger diameter than the casings 14 are positioned so that they may receive at the upper ends the lower projecting ends of the casings 14, the casings being coupled as by rivets. The screws 7 are again withdrawn, cross members 21 inserted in slots in the casings 20 and the procedure of building the storey repeated, each storey being elevated on completion through one storey height. The casings may be filled with preferably a rapidly binding concrete and reinforcement may be provided, e.g. through a longitudinal opening in the casing. The lifting may be effected by hydraulic jacks. The wall elements may be provided with external mortar and an internal insulating covering, and the floor sections may be provided with an insulating layer in addition to a wearing layer, e.g. parquet slabs. The wall and floor sections are formed with conduit channels and are provided with conduits and fittings that may be connected rigidly to the building elements.
