Inventor: LAUFER THEODOR
IPC: B64C1/00
Filed: 1948-02-03
Abstract: 649,910. Helicopters. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. Feb. 3, 1948, No. 3176. Convention date, Feb. 7, 1947. [Class 4] In a helicopter of which the rotor is capable of universal tilting movement, the cyclic pitch control linkage includes a lever with three pivots, of which two are connected to portions of the linkage while the third is connected to a member carried by the rotor pylon through a damped resilient connection. As shown in Fig. 1, the rotor is connected to the driving shaft 3 by a universal joint 6 and the spider 8 actuating the cyclic pitch control linkage 10, 11, 7 is operated by a rod 9 passing through the shaft 3. The inner end of each link 11 is connected to a gimbal member 12a, 12b, while each blade 2 is connected with a lower gimbal member 22a, 22b by a link 23. The gimbal members are connected by links 13, 18 and a dashpot 17, the link 13 being connected to a ring 14 subjected to opposed springs 19, 20. The arrangement is such that tilting of the rotor has substantially no effect on the pitch control arms 7. The damping mechanism may be rendered inoperative to allow unrestricted tilting of the rotor by locking the ring 14, which in the arrangement shown is effected by supplying compressed air to an inflatable tube 27. In the arrangement shown in Fig. 6, the rotor hub is carried by a universal joint 35, and the connection of the third pivot of each lever 11 to the pylon is effected by a link 24, damper 17 and spring 20. Further constructions embodying similar damping arrangements are also described. Specifications 570,404 and 580,231 are referred to.

A program store 2 normally accessed i.e. response to successive clock pulses from generator 1 but which may be accessed, e.g. for program branches, in response to signals from the processing units via 21, provides op codes to control the processing units which may be microprogram controlled devices, switching instructions for multiplexors 9, 10, and addresses to access stores 3-8. The stores include an I/O buffer 6, a working store 8, and a permanent store 7. The "short" processing unit 4 is said to perform simple operations such as comparisons on single digits and is connected to a buffer store 3 which supplies a multiplexor 10 connected to external sources. The arrangement is controlled so that the processing occurs simultaneously in units 4, and 5, several operations being performed by 4 for each operation by 5. Each of the stores may have an associated checking device, e.g. a parity checking device or a diagnostic device using test words, to detect failures. The system is said to be of use in flight navigation. The stores may be of various speeds, e.g. store 6 is a high speed semi-conductor device and store 3 may be a magnetic core device. It is stated that store 6 may perform two cycles in each machine cycle, determined by clock 1 which synchronizes the operation of all units.

Title: Method and apparatus for detecting the expulsion of molten metal in resistance welding
Inventor: TARAN JURY MATVEEVICH
IPC: B23K11/25
Filed: 1969-01-21
Abstract: 1,259,988. Welding by pressure. INSTITUT ELEKTROSVARKI IMENI E.O. PATONA. 21 Jan., 1969, No. 3295/69. Heading B3R. In resistance welding molten metal expulsion is detected by converting the energy of the shock wave caused by expulsion into an electric signal and registering the time of occurrence and magnitude of this signal to indicate the time of occurrence and magnitude of the expulsion. In an embodiment a transducer 1, Fig. 2, is secured to electrode 2, the transducer comprising a piezo-electric cell for converting the shock wave caused by expulsion into an electric signal. A discriminator 4 connected to the output of the transducer 2 separates and amplifies the signals from the transducer and supplies an indicator 5, e.g. an oscilloscope and a relay 6 which causes the operation of a light or sound-signalling device to indicate expulsion or of devices to reject and sort articles welded with or without expulsion. The discriminator 4 which receives an input from the welding transducer 7 to mark the beginning and end of the weld comprises a band-pass filter 8, Fig. 3, connected to the transducer 1 to separate and amplify signals in the range of 20-50 kc. per sec. and suppress signals outside this band. The transducer 7 is connected to a unit 11 which converts signals from the breaker into signals for triggering a gate generator 9 in the form of a Schmitt trigger, delay lines 12, 13 being provided between the unit 11 and the generator 9. The filter 8 and generator 9 are connected to an amplitude and time selector 10 which separates and amplifies those signals it receives simultaneously with the gating pulses, which exceed a preset level. To measure the parameters of several expulsions at one weld point a number of gate generators and selectors 10 are employed. In use in the course of welding the output of the transducer includes signals relating to the operation of auxiliary parts of the welding apparatus, low frequency signals caused by pressure changes due to heating and the high frequency shock signals. The filter 8 allows only those signals of 20- 50 kc. per sec. to pass to the selector 10 which also receives square-wave pulses corresponding to the time of welding current passage and the high-frequency shock pulse and a squarewave pulse arrive at the same time and the selector 10 emits a pulse indicating expulsion. This pulse is measured by indicator 5 and triggers relay 6.

Abstract: 1301141 Spray carburetters; heating charge DYNATECH CORP 23 Jan 1970 [29 Jan 1969 7 July 1969] 3310/70 Heading F1B During idle operation of an I. C. engine with the throttle valve 34, Fig. 1, fully closed, the incoming flow passes into a secondary flow line 42 where it receives fuel through idle line 50 and is subsequently heated by an electric heater, an afterburner or, as shown, by an exhaust-gasheated heater 48, whereafter it passes to the engine cylinders via manifold 16 and ports 18, 20, 22, 24, line 50 may be connected directly to carburetter 15 or to manifold 16. During full load operation with throttle valve 34 fully open, the pressures at opposite ends of secondary flow line 42 are substantially equal so that flow therethrough ceases and the engine is charged with unheated primary mixture. Part load engine operation produces a partially heated charge resulting from intermixing of the primary and secondary flows. The temperature of the charge is therefore varied from a maximum (between 400 and 1000‹ F.) at idle conditions to a minimum (ambient temperature) at full load conditions. The fuel to air ratio is arranged to be very lean over the operating range of the engine, e.g. between 0À04 to 0À06 for minimum and part load, and approximately 0À07 for full load. Fuel is drawn from carburetter bowl 30 into Venturi 28 by primary air-flow, via line 32, orifice 58, and orifice 59 which is opened with increasing manifold pressure and therefore engine load. A port 54 permits dumping of the fuel-air mixture trapped in line 42 after sudden opening of throttle valve 34. In an alternative embodiment, Fig. 2 (not shown), the secondary flow line (42<SP>1</SP>) receives air direct from the ambient and discharges the heated mixture into the manifold (16) at positions adjacent inlet ports (18, 20, 22, 24). In another embodiment, Fig.4 (not shown), the carburetter is omitted and the fuel is injected, and heated secondary air is delivered, directly into a primary air inlet manifold (70) at positions adjacent inlet ports (82, 84, 86, 88).

[Class 40 (v)] In order to shorten the return time of sawtooth oscillations generated by a blocking oscillator, the grid blocking condenser is arranged to be charged not only by grid current but also by the current in a further circuit associated with the oscillator. As shown in Fig. 1, the blocking condenser 15 is placed in the cathode lead so that it is charged by both grid and plate currents, and discharges through a resistance 17 and inductance coil 16. Sawtooth voltage may be taken off across the condenser 15 or from a coil coupled to the coil 16. Controlling impulses are applied to a third coil 14 on the back-coupling transformer 11, 12. The grid may be biassed positively. In Fig. 2, a screen-grid valve is used, and the back coupling is between the screen and the inner grid. The anode is connected to the positive side of the source 19 through a resistance 20, and to the negative side by a condenser 21. The time constant of this circuit is made equal to that of the circuit 15, 16, 17, and push-pull saw-tooth oscillations are taken off from the anode and cathode. In Fig. 3, the grid condenser 29 is connected to the positive or negative side of the supply source 31a through a leak resistance 30. The anode is connected through the back-coupling coil 31 and the resistance 32 to H.T. +, and a condenser 33 is connected between the resistance 32 and the grid condenser 29. Saw-tooth voltage is taken off across the condenser 29. A screen may be provided in the valve and used for back coupling, the anode being connected directly to H.T. +, Fig. 4 (not shown). In Fig. 5, the cathode lead includes two condensers 37, 38 shunted respectively by a resistance 40 and a coil 41. Both are in the anode circuit, but only the condenser 37 is in the grid circuit. The anode circuit also includes a coil 42 and condenser 43, and push-pull oscillations are produced across the condensers 38, 43.
