Title: An improved automatic safety device for use in connection with electric air heaters
Inventor: PANISSET DENIS SYDNEY
IPC: F24H3/04
Filed: 1948-07-24
Abstract: 643,695. Protective cut-out arrangements; automatic circuit-breakers. SIMPLEX ELECTRIC CO., Ltd. July 24, 1948, No. 19848. [Class 38(v)] In a protective device for an air heating element, a switch controlling the supply of power to said element is operated by a mechanical linkage capable of being disrupted by an electromagnet to open the switch on failure of the air supply. The linkage comprises an operating rod 19 pivoted to a link 28 also pivoted coaxially with a switch lever 17 connected through a leaf spring 21 to rod 19. Fig. 2 shows the switch in the " on " position, spring 21 being in a state of compression due to the action of a return spring 18 so that it presses against an abutment 2 on the armature 23 of the electromagnet 24 and the rod 19 being held by a latch (not shown). The coil 10 of the electromagnet, in Fig. 4, is connected in series with the heating elements 14 through the switch 13 and is shunted by an element 15 having a high temperature coefficient of resistance and placed in the air stream passing over elements 14. Failure of said air stream will cause the temperature and hence the resistance of element 15 to rise thus increasing the current flowing through coil 10 until it reaches a point at which armature 23 is attracted. Normally the resistance of elements 14, or an alternative resistance, plus the shunting effect of element 15 maintains the current through coil 10 below this point. The abutment 2 then deflects spring 21 over its centre causing it to assume a bowed shape and simultaneously opening the switch. In order to prevent operation of the device as a result of fluctuations in the supply voltage, a compensating winding 11 shunted by an element 16 similar to element 15, but riot placed in the air stream, may be provided. The coils may be arranged in line with the armature between them and normally nearer the coil 11, so that when coil 10 is energized sufficiently for the armature to operate the switch the latter moves over with a snap-action, Fig. 5 (not shown). The device is reset by moving rod 19 downwards in the drawing to the switch " open " position and releasing the switch.

Abstract: 593,354. Signal combining circuits. WESTERN ELECTRIC CO., Inc. Nov. 29, 1943, No. 19941. Convention date, May 1, 1941. [Class 40 (v)] [Also in Group XXXVIII] Signals from a number of sources A ... C, each of which has one terminal grounded, are combined by connecting the other terminals through individual high impedances 1 ... 3 to the input circuit of an amplifier having a feedback resistance 16 which reduces the effective input impedance. The circuit shown is for signals having a D.C. component and it is arranged, with the aid of a potentiometer 17, that in the absence of signals, the last anode is at ground potential. Values of the components in a typical circuit are given. By adjusting the relative values of the impedances 1 ... 3, which are resistant except when the signals are to be modified in accordance with frequency, it can be arranged that the signals from one or more sources are in effect multiplied by desired factors.

Abstract: 1,026,340. Rolling. F. MOELLER, and K. NEUMANN, [trading as VERWALTUNGSGESELLSCHAFT MOELLER U. NEUMANN OFFENE HANDELSGESELLSCHAFT]. May 21, 1963 [May 23, 1962], No. 20164/63. Heading B3M. A universal roll stand comprises two frames which, including the vertical rolls secured in them, can be moved on soleplates by four horizontal screwed spindles, the vertically adjustable horizontal rolls being retained in their axial position independently of the frames, and the drive for the spindles, which are all in driving engagement with each other, being secured to one frame. The chocks 5-8 of horizontal rolls 3 and 4 and 38 and 39 of vertical rolls 36 and 37 are secured in the frames 1 and 2 of a universal stand, four screwed spindles 19-22 (Fig. 2, not shown) being synchronously driven by two motors 31 to shift the frames 1 and 2 equally and oppositely on soleplates 15. Alternatively, frame 2 may be fixed such that frame 1 and also the pass line moves, the use of non-telescopic roll driving spindles then being possible. Motors 13 acting through screws 9 and 10 give vertical adjustment of the rolls 3 and 4. The chocks 5-8 of the rolls 3 and 4 are attached by pairs 60 to the chocks of rolls 36 and 37, the chocks 5-8 sliding over the moving roll spindles as the frames and vertical rolls are adjusted. The chocks of rolls 36 and 37 are in turn clamped to the frames 1 and 2. As shown in plan (Fig. 5, not shown) cams 44 and 45 on rotatable shafts 42 and 43 can co-operate with slots 44b, 39a, 44b and 38a in the roll chocks 39 and 38. Drives 48 rotate the shafts 42 and 43. The horizontal rolls are adapted to be connected, at their ends remote from the roll driving spindles, to the screwed spindles 19-22. To this end the rolls are provided with lateral extensions for engagement by pivoting arms 53. These arms can be held in or out of engagement with the extensions by means of cylinders 54. Hand wheels 57a and 55b, Fig. 1, allow adjustment of the axial position of the extensions on each roll spindle. Balancing of the rolls is by mechanisms 61 and 64. Reversal of the entire roll set is possible by retraction of the screwdowns, rotation of the cams 44 and 45 and hydraulically raising rails 41 until the roll set is supported and can be shifted laterally. The vertical roll chocks may be replaced by spacers and the stand used as a 2-high mill. Hydraulic expanders (Fig. 3, not shown) are situated between frames 1 and 2 to prevent backlash when operating the screwed spindles.

Abstract: 697,267. Travelling-wave tubes. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Aug. 29, 1951 [Aug. 30, 1950], No. 20381/51. Class 39(i) [Also in Group XL(c)] A travelling wave tube is made to operate as an oscillator by the provision of wave reflecting means 35, 37 at or near each end of the slow wave structure, as shown a helix 3, and one of the reflectors 37 is adjustable along the axis to ensure that the spacing between the two reflecting means can be made equal to an integral number of half wavelengths at the desired frequency of operation. The helix is terminated at either end by transition sections 27, 29 of varying pitch wound in grooves 33 in hollow conductive members 31 which convert the longitudinal E wave on the helix to a radial or TEM mode which is stated to be more easily reflected without the generation of higher order modes. Reflectors 35, 37 may be coupled to inner and outer conductors 31, 32 conductively and/or capacitatively, for example as shown, and reflector 37 is adjustable for fine tuning and determination of the correct number of half wavelengths by means of linkage comprising piston 41, screw 43, gears 45 to crank handle 47. Coarse tuning is obtained by variation of the beam accelerating voltage by means of adjustable voltage dividers 21, 23, the helix preferably being highly dispersive and so frequency selective. 11 and 13 are focusing electrodes and 15 is an accelerating electrode; lead 25 connects the helix 3 to the collector 5. Cylinder 32 may be omitted except in the immediate vicinity of reflectors 35, 37. Energy is removed by coupling loop 34 and coaxial line 36. The tube envelope 7 is of quartz. The device may be used as a signal generator or as a local oscillator in a microwave superheterodyne receiver. Specification 668,513. [Group XL(b)], is referred to.

Abstract: 1,117,350. Theft alarms. J. STANLEY. 6 April, 1967 [10 May, 1966], No. 20635/66. Heading G4N. [Also in Divisions F1, F2 and H1] In an anti-theft device for a motor vehicle a valve 2 is included in the supply line to the fuel pump and a diaphragm 4 is arranged to be actuated by the fuel pump when the valve is closed so as to initiate an electrical warning device. As described, the vehicle is immobilized by pulling a cable 10 to the left which closes a three-way valve 2, interrupting the supply of fuel to the fuel pump and opening a port between a chamber 16 and the fuel pump. Unauthorized starting of the vehicle will cause the fuel pump to evacuate chamber 16, deflecting diaphragm 4 downwards and moving an insulating cylinder 5 into a position whereby contacts 7 are bridged by a conducting sleeve 6, thus sounding the horn 14 and initiating a solenoid-operated camera 15 with synchronized flash. The engine will stop shortly due to fuel starvation. The device is inhibited by manual operation of shaft 17 and cable 10. The valve 2 may be operated by a solenoid and may be located on the fuel pump remote from the diaphragm 4.

Title: Improved method of producing concentrated formic acid and nitrate
IPC: C01B21/46
Filed: 1950-08-21
Abstract: Formic acid is produced by reaction of a formate and concentrated nitric acid of at least 65 per cent by weight HNO3 in presence of formic acid as a diluent, the reaction mass being subjected to a fractional vacuum distillation to yield a first distillate of concentrated formic acid, and a further distillate of more dilute acid.  The nitric acid is preferably in slight excess, and an amine or urea added as a buffer or stabilizer.  The formic acid diluent is of 65-80 per cent concentration, for example 70-72 per cent with 98 per cent nitric acid, and in an amount of at least 1, preferably 2-3, equivalents for each equivalent of formate.  In an example, to a mixture of calcium formate, urea, and formic acid, cooled to 20-25 DEG  C., 98 per cent citric acid is added, and the mixture distilled at 20-30 mm.  The first fraction, collected at 31-35 DEG  C., is 88.5 per cent formic acid.  The next fraction, collected up to 113 DEG C., is used as a diluent for a new charge.

Abstract: 953,067. Parametric amplifiers. SIEMENS & HALSKE A.G. June 13, 1960 [June 11, 1959], No. 20753/60. Heading H3B. In a parametric amplifier, the pumping frequency f 0  from a generator J 0  is lower than the signal frequency f 1  from a source J 1 . The pumping and signal frequencies are fed over circuit branches 0 and 1 to a diode represented by four fixed capacitors C o  and a variable capacitor C v . Branches 2 and 3 are tuned to encourage idler frequencies f 2  = f 1  - f 0  and f 3 =f 0 -f 2  = 2f 0  - f 1 , f 3  being described as an image frequency. Thus there are two amplifying processes represented by 2f 0  = f 1  + f 3  and f 0  = f 2  + f 3 . In another embodiment, Fig. 5, the diode 2 is mounted in a waveguide 1 at a distance of one quarter wavelength of the signal frequency f 1  from the shortcircuited termination. The pumping frequency f 0  is fed to the diode by a coaxial line 4. Another coaxial line 3 is tuned to offer a substantially pure resistance to the idler frequency f 2 . An impedance transformation line section 5 and a band-pass filter 6 pass the signal frequency f 1 , and stop the image frequency f 3  to which they offer a substantially pure resistance as seen from the diode 2. A further embodiment, Fig. 6, includes a diode 12 in a system of coaxial lines, as shown, linked by a waveguide 8 to a circulator 7 through which the signals are fed to and extracted from the amplifier.
