Title: Improvements in engine pistons
IPC: F02F3/22
Filed: 1928-11-01
Abstract: 325,194. Shannon, D. M., and Fiat British Auxiliaries, Ltd. Nov. 1, 1928. Pistons.-In a piston in which the depending portion C, Fig. 8, of the head is made of tapered cross-section, the flow of heat to the upper packing-ring grooves is obstructed by means of plane or inclined grooves D<2>, or by means of cylindrical grooves cut in the piston crown. The grooves may be filled with insulating material. The axes of the grooves may be eccentric to the piston axis, in order to secure a greater flow of heat to the side of the piston which is pressed against the cylinder wall during the working stroke. Instead of grooves, rows of holes may be employed, or a hollow space E<2>, Fig. 6, may be cast in the piston head. The core used in casting this space may be removed in the usual manner, or may be of insulating material, which is left in position. Alternatively, the space may open to the periphery of the piston, as shown, and be covered by a shrunk-on ring d<1> having a shoulder d<2> to prevent displacement. The head A<1>, Fig. 8, may be separate from the skirt A<2>, and be formed of nickel steel, or other metal having a low coefficient of expansion.

Title: Improvements in or relating to camera pick-up equipment
IPC: B42F5/06
Filed: 1967-07-11
Abstract: 1,128,587. Television. NIPPON ELECTRIC CO. Ltd. 11 July, 1967 [19 July, 1966], No. 31834/67. Heading H4F. To detect reduction in beam current and maintain the correct value of beam current in a television camera storage type pick-up tube, e.g. a vidicon or an image orthicon, the electron beam is modulated with a periodic signal, preferably having a higher frequency than the highest frequency of the video signal, and the periodic signal is detected in the output video signal and used as a control signal for increasing the beam current. In the embodiment described an alternating current from a modulation wave oscillator 2, Fig. 1, is applied to a cathode K (or to one of the other electrodes) of pick-up tube 1 to modulate the beam current. If the beam current is insufficient, the modulation wave will appear in the output at portions corresponding to video signal highlights. The video signal current and the modulation wave are amplified 3 and by means of a process amplifier of only sufficient frequency bandwidth to amplify the video signal, the video signal appears at output 5. The modulation wave component is extracted from the video signal by a band-pass filter 6, converted to direct current by a rectifier 7, amplified by a direct current amplifier 8 and applied to the grid G of the tube through a beam current declining mixer 9 to increase the beam current. When the beam current is not insufficient the mixer slowly decreases the beam current. The mixer may comprise a circuit as shown in Fig. 3, point a being connected to a power source of which the potential is negative with respect to the cathode K and fixed so as to cut off the beam current when the grid G potential becomes equal to it. Point b is connected to the output of amplifier 8, the potential at which cuts off or makes insufficient the beam current when no modulation wave component is present in the video signal, and makes sufficient the beam current when the modulation wave component is present. Insufficiency of the beam current raises the potential at b causing diode D to conduct and make the grid potential nearly equal to that at b. When the beam current increases and its insufficiency disappears the potential at b decreases causing the beam current to decrease. However due to the time constant of CR the grid potential decreases slowly and diode D will not conduct until the grid potential equals the potential at b. Thus the beam current decreases automatically to prevent excessive beam current and when the current is insufficient the direct current amplifier increases the potential at point b to cause an increase in the beam current. The beam current declining time constant i.e. the time constant of CR, is preferably determined to be sufficiently long compared with a frame period.

Title: Improvements in and relating to coin-freed prepayment and price-changing mechanism
IPC: G07F15/08
Filed: 1922-11-21
Abstract: 214,289. Alder & Mackay, Ltd., Chamberlayne, A. F., and Healey, A. J., (Representative of Glover, T.). Nov. 21, 1922. Coin action, mechanical connection; coin-slit closing-devices.- In prepayment mechanism for gas meters of the kind having a price-changing disc which does not rotate with the coin carrier, the coin carrier r, Figs. 3 and 5, is loosely mounted between two sets of cams i, j on a shaft e turned by a handle f, the shaft having a bearing, in a quantity wheel v and in a price-changing disc a. The coin is inserted through a slot h in a guard slate g fixed to the shaft e outside the price-changer a, and through a slot c in the price-changer, into the coin carrier which has pivoted at t a subsidiary carrier s provided with a projecting tooth u. On turning the handle, the plate g closes the slot c, a cam surface l on the cam j forces the coin forward to engage the tooth u of the carrier s with the quantity wheel v, and then a projection o on the cam i rotates the carrier r. A ring d fixed to the back of the price-changer and gapped at the slot c holds the coin in its forward position. A spring controlled latch m pivoted to the cam j prevents retraction of the coin. The carrier is returned to coin receiving position against a stop 7 by a second projection p on the cam i, a snail q between the projections o, p disengaging the tooth u from the wheel v. A pawl y prevents backward rotation of the wheel v and a second pawl z prevents return of the carrier before the coin is discharged. Price-charging mechanism.-The price-changer a is held in adjusted position by a fork on the casing engaging two of a series of peripheral notches and by a flanged ring 2 hinged at 3 and secured by a screw 4. The markings on the price-changer are visible through a hole in the flange of the ring.

Title: Fourier transform nmr spectroscopy employing a phase modulated rf carrier
IPC: G01R33/36
Filed: 1975-07-30
Abstract: 1500919 Magnetic resonance spectrometers VARIAN ASSOCIATES Inc 30 July 1975 [1 Aug 1974] 31889/75 Heading G1N In a magnetic resonance spectrometer the sample is excited by RF energy of sufficient bandwidth to simultaneously excite several resonance lines, this energy being generated by periodically shifting the phases according to a predetermined sequence. The resonance signals are detected, time scanned and sampled to give a series of components, and the components are stored, averaged and Fourier analyzed; the resulting spectrum is free of anomalous phase and intensity effects which can occur when regular pulses of RF energy are used to generate the broadband excitation. In Fig. 1, the excitation is generated by operation of a phase shifter 13 which, under control of unit 15, switches the phase of a carrier produced at 11; the phase shifted signal is gated into pulses at 14, amplified and supplied to the sample at 12. The receiver 17 is gated to be on only between excitation pulses, and its output is phase detected and converted to a line spectrum in the usual manner. The phase shifter may be set of phase shifting elements switched by unit 15 to produce shifts of 0 degrees, 90 degrees, 180 degrees or 270 degrees; alternatively the transmitter 11 may produce a frequency n times the desired frequency, and may be coupled to the gate 14 by a circuit which causes a delay of a whole number of cycles followed by a divide by n circuit, Fig. 5 (not shown).  The excitation is supplied in i different phases, e.g. four phases 0 degrees, 90 degrees, 180 degrees, 270 degrees; in Fig. 3, these phases are indicated as A, B, C, D. The excitation may simply comprise a series of pulses of phases ABCDAB etc, but it is preferred to divide the excitation period into i equal sections, i.e. four sections 1-4 in Fig. 3, and to supply in section 1 all the phases in turn, then in section 2 every second phase, in section 3 every third phase, and in section 4 every fourth phase.

Abstract: 754,079. Coating electric conductors with thermoplastic insulation. PIRELLI-SOC. PER AZIONI. Nov. 4, 1954 [Jan. 13, 1954], No. 31917/54. Class 87(2) In making submarine telegraph or submarine telephone cable, before the main coating of thermoplastic insulation is applied to the conductor 5 the later is heated and passed rightwards through a chamber 1, through which thermoplastic material flows leftwards under pressure and emerges at 7. The thermoplastic material " washes" the conductor and applies a preliminary thin coating of material thereto. The conductor may be a single solid wire. Alternatively the conductor may be a stranded conductor (swaged or not swaged), in which case 'air bubbles are washed off the conductor and thermoplastic material is forced into the interstices between the strands. The conductor 5 may be 45 mm. in diameter and the bores of the dies 3 and 4 4.7 and 4.6 mm. respectively. The conductor may be heated to a temperature 50-100C. greater than that of the thermoplastic material. The device shown in the drawing (which may be modified in that the screw may be replaced by another impeller, e.g. a gear pump) may be separate from, in series with or part of an extruder or other machine for applying the insulation proper. If the device shown is separate from the second machine the initially-coated conductor is heated a second time before 'passage through the second machine. The material for the " washed' coating may be guttapercha or polyethylene, and the material for the insulator proper may be the same or slightly different.

[Also in Division G3] Temperature programming means for gas chromatography columns (12)-(15) (see Fig. 1, not shown) contained in oven 9 comprises a temperature regulator 29 and a phase changer 30 both connected through control pulse generator 31 and thyristor switch 25 to heaters 24 in oven 9. Regulator 29 comprises amplifier 33 and bridge circuit 32, one arm of which contains temperature sensitive element 22 in oven 9 and another arm isothermal level programmer 27. Phase changer 30 comprises trigger pulse shaper 35 and bridge circuit 34, one arm of which contains programmer 28 which controls the rate of change of heating current supplied to heater 24. To operate the system, switches 40-43 and timer 48 are set in accordance with the desired temperaturetime program. Timer 48 initially closes switches 44, 45 and until the resistance of element 22 balances resistor 36, the unbalance signal amplified and converted into d.c. by amplifier 33 is applied to trigger generator 31. Simultaneously, a phase-shifted a.c. is converted by shaper 35 and applied as trigger pulses to generator 31. When the two pulses applied to generator 31 arrive together, generator 31 produces a control pulse which switches on thyristor 25 to the phase-shifted a.c., the degree of phase shift, governed by resistor 38, determining the mean value of the heating current applied to heaters 24. When balance is reached, no signal is produced by amplifier 33 and control pulse generator 31 is switched  off, rendering thyristor 25 non-conductive. The isothermal level is thereafter maintained by conventional means. In accordance with the temperature program, timer 48 subsequently opens switches 44, 45 and closes switches 46, 47 causing a further heating of oven 9 in accordance with the values of resistors 37, 39.
