Title: Method of producing blade rings for radial-flow elastic-fluid turbines
IPC: F01D5/04
Filed: 1929-06-29
Abstract: 314,868. Aktiebolaget Ljungstr÷ms Angturbin. July 3, 1928, [Convention date]. Turbines. - In radial flow turbines the blades 10 are collected to form a drum and the roots 15, 16 are machined, so that they may be secured to corresponding ring bonds 11, 12. Figs. 4 and 5 show a method of assembling the blades 10. They are arranged root-to-root to form a drum and are held by clamps 21, 22. An easily fused metal is poured through an opening 23 into the annulus between the clamps to keep the blades in position, and the surplus metal 20 on the roots is then machined off. In Fig. 4 the ribs 17, 18 on the blade roots are formed with screw threads for engagement with the threaded ring bonds 11, 12. In Figs. 6 and 7 the roots 15, 16, and rings 11, 12 are formed with tongues 30 and slots 32 which make a bayonet joint. In a modification the tongues 30 are threaded so that an interrupted-thread joint is formed. In a further modification, Fig. 16, the joint is dovetailed, and the parts are locked by bending over the edge 34. In assembling, the ring bonds 11, 12 are held temporarily in clamps 26. When the rings have been attached to the blade roots and locked, the easily fused metal is melted out.

Title: Method for processing a subtractive motion picture film
IPC: H04N1/60
Filed: 1957-06-26
Abstract: 863,794. Copying in colour. GRETENER, E. June 26, 1957 [May 8, 1957], No. 20178/57. Addition to 791,676. Drawings to Specification. Class 40(3) Relates to a modification of the method described in the parent Specification for producing in a four-colour reproduction process a neutral colour separation image whose density at each point corresponds to the smallest of the three subtractive colour densities. This method involves the production by purely photographic steps of a first image, the basic image, whose density corresponds to a combination of the three colour components of an original, and the production by photoelectric point-by-point scanning of a second image, the correction image, whose density corresponds to the ratio of the greatest of the colour components to their sum (equivalent to the ratio of the smallest to the sum in terms of the subtractive densities). The neutral colour image is then produced by combining the basic and correction image. In accordance with the present invention the need to produce an intermediate photographic copy of the basic image is avoided. The neutral image is produced by direct photographic copying from an original three-colour transparency with the interposition in the light path as a mask a film carrying the correction image and produced as described in the parent Specification photo-electric scanning of the original. The spectral sensitivity of the copying light and the reproducing film is chosen so that, in the absence of the correcting mask, the neutral image would correspond to a combination (preferably the sum) of colour components in the basic image. Specification 791,675 also is referred to.

Abstract: 1515773 Locking safety belt retractors TAKATA KOJYO CO Ltd 17 May 1976 [17 May 1975] 20223/76 Heading A3V A safety belt retractor comprises a spring biased take up reel whose shaft carries a ratchet wheel 1 and a drive wheel 5 a pawl 2 being provided to lock the ratchet wheel, the pawl being raised by an actuating member 9 slidable along a path tangential to the drive wheel 5 and which has a retracted position as shown in Fig. 1, an intermediate position where a coupling element 7 engages the drive wheel 5 and an extending position in which it lifts the pawl 2 into engagement with the ratchet wheel 1, means also being provided to lift the actuating member to its intermediate position in response to a predetermined acceleration. This latter means as shown is a pendulum 3 whose movement raises a member 4 which engages a part 6 of the actuating member. The acceleration sensor can also be a steel ball in a pan or an inverted conical weight. When the actuating member is in its intermediate position tension on the belt D rotates the drive wheel 5 which raises the actuating member to its extended position and in so doing lifts the pawl 2 into positive engagement with the ratchet wheel I and avoids the pawl skipping a tooth of the ratchet. The retractor may be additionally provided with a lock responsive to belt extraction or a mechanism restraining the winding force on the seat belt during normal driving.

Filed: 1962-02-21
Abstract: 964, 818. Automatic temperature control systems. BRITISH INSULATED CALLENDER'S CABLES Ltd. May 21, 1963 [Feb. 21, 1962], No. 20227/63. Divided out of 964, 817. Heading G3R. A heater having a positive temperature coefficient such as an electric blanket comprises series connected elements 25, 26 which are disconnected from a supply 1, 2 by a series relay having contacts 7, 10 and coil 17 when the heater cement falls to a determined value. Reconnection after a time delay is made by time operated contacts 8, 9 reclosing. This energizes heaters 11,12, one of which is shunted by contacts 4, 14 to reduce the heating when contacts 8, 9 open, this also increasing the shunting effect on coil 17 so that the relay differential is reduced. A rear tube 21, 22 is connected across each element 25, 26 so that an open and shut circuit in either of the elements fires one or both of the tubes, thus blowing a fuse 4. Another tube 5 indicates the presence of the supply. A capacitor 19 prevents chattering of the contacts 7, 10 due to the half wave rectification of the supply by diode 18.

Title: Improvements in or relating to electric heating devices
IPC: H05B6/02
Filed: 1921-07-28
Abstract: 185,300. Hamers, H. J. W., Buiskool, M., and Sillman, W. J. July 28,1921. Heating by electricity.-In an electric heater of the type wherein the heating-element consists of a tube 4 constituting the secondary winding of a transformer and through which flows the air, steam or water to be heated, the tube 4 is enclosed by a container 6 through which the fluid to be heated circulates in direct contact with the outside of the tube. In the heating system shown the heater is fitted in series with a circulating fan or pump 7 and a radiator 13. For heating by air, the radiator 13 may be omitted. The current supply to the primary winding 3 from the mains 32, 33 is automatically controlled by the temperature or pressure of the fluid. When the pressure or temperature of the fluid falls below a certain value, the rod 19 descends and makes contact with the wedgepiece 23 on the rod 22, and thus completes the circuit through the coils of the electromagnet 27. The core 26 of the magnet attracts the rod 22 against the action of the spring 25 and completes the circuit through the rods 22, 26, the regulating resistance 31 and the primary coil 3. The rod 19 is lifted by the wedge 23 and descends again at the back thereof, and the circuit through the magnet coils is broken by the insulating wedge 28 which forces the spring 30 away from the rod 22. When the pressure or temperature of the fluid rises above a certain value, the rod 19 is pulled away from the con. tact 23 and the sping 25 restores the rod 22 to its original position, thus breaking the primary circuit.

Abstract: 1343973 Variable speed gear control REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 19 April 1971 [26 Jan 1970] 20312/71 Heading F2D The continuous or stepped gear changes of a variable speed transmission are controlled by electronic data processing apparatus (e.g. printed circuits 28, 29) housed with a transmitter of vehicle speed and engine load data (e.g., a tacho-generator 9 having poles movable by a Bowden cable connection to the throttle) in a common easing mounted on the casing 14 of the transmission. The common casing may be split into an insulating fibre filled (polyamide) part 16 and an electrically and thermally conducting (die cast aluminium part 17) bolted together to provide two chambers 18, 19 sealed by O-rings 21, 22. The tacho-generator 9 may be driven via a gear (7) Fig. 1 (not shown) meshing with a crown gear (6) of the vehicle differential. The electronic circuit, Fig. 4, may comprise a double output coil 35 of the tacho-generator 24 whose output signal is rectified by diodes 36, 37, filtered by capacitors 39, 40 and resistor 38, the resulting load-factored speed signal via selected resistors 56 ... 61 and amplifiers 41, 42 controlling members 13a, 13b (e.g., solenoid valves controlling hydraulic slide valves). The frequency of the signal from the coil 35 independent of the load factor may be fed to the base of a transistor 44, and thence via a circuit of resistors 48 ... 50, capacitors 45, 46 and a diode 47 to produce a speed responsive voltage across the resistor 48. This may be fed to an amplifier 51 together with a different load factor signal at 54 from a potentiometer 56, Fig. 2, in the casing 17, to control a further member 53 such as a twoposition abutment switch to cut off the engine fuel supply at high speeds, or to move an abutment in the throttle to give a second idling speed.

Abstract: 381,968. Discharging condensers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. July 17, 1931, No. 20522. Convention date, July 17, 1930. [Class 38 (iv).] In an X-ray installation comprising a condenser 2, Fig. 2, which is charged up by a transformer 3 through a rectifier 4, and when sufficiently charged can be made to discharge through the tube 1, an inductance 6 is included in series with the tube. The effect is to modify the voltage-time curve 7, Fig. 1, to that of 8 whereby the minimum useful voltage e<3> across the tube is reached earlier at t<4> and does not fall below this till t<4> the period of utility t<4>, t<5> being greater than t2, t<3> without the inductance. A condenser having a smaller capacity can be used and less energy suffices. The advantage is enhanced if the inductance has a magnetic core which becomes saturated when the discharge current is at its maximum. A spark-gap 5 may be used to prevent premature discharge through the tube 1. Alternatively the establishment of the discharge current may be effected by supplying a suitable potential to an auxiliary electrode, or by the establishment of the cathode heating current of the tube or of a discharge tube in series with the latter. The secondary coil of the supply transformer may itself be used as the inductance. For example in the modification of Fig. 3, the Rontgen tube 13 and the spark-gap 14-15 are in parallel with the rectifier 12, the discharge taking place through the secondary coil 11. A second adjustable spark-gap 14-16 may be provided bridging the former gap and the transformer winding, and either gap can be made operative. A separate inductance 17 may be used for the spark-gap 14-16 circuit.
