Title: Method of and apparatus for resistance welding
IPC: B23K11/06
Filed: 1970-01-15
Abstract: 1,271,603. Welding by pressure. CONTINENTAL CAN CO. Inc. 15 Jan., 1970 [31 Jan., 1969], No. 2092/70. Heading B3R. In resistance welding overlapped edge portions of a metallic blank a pressure in the range of 80,000 to 100,000 p.s.i. is used while a current density through said portions of 1 Î 10<SP>6</SP> to 5 Î 10<SP>6</SP> a.s.i. is maintained. As shown, blanks 11 are fed by advancing means 13 along a horn 12, bent to tubular shape with overlapped edge portions 15, 16 by forming means 14, tack welded along the seam by means 28 and then fed between opposed roller or sliding electrodes 18, 20 urged together under pressure and supplied with current. The pressure face is applied by an actuator to the electrode 20. The pressure may be of the order of the yield strength of the metal of the blank. Preferably the pressure varies with time so that it is lower during entry of the blank between the electrodes than thereafter. Lateral flow of metal at the seam is assisted by the use of one flat-periphery electrode and one curved-periphery electrode (Fig. 5). Feedback means such as an X-ray gauge or eddy current gauge and/or a heat sensitive gauge (Figs. 6 and 7, not shown), may be provided to control the heating and pressureapplying functions.

Title: Improved regulating device for heaters or boilers for sizing, finishing and dye-baths
IPC: D06B23/22
Filed: 1951-01-29
Abstract: A process for the preparation of sizing, dyeing, finishing, or like baths comprises the steps of heating the crude bath to a predetermined temperature automatically maintaining the temperature constant by electrical control for a predetermined time and, if necessary, thereafter removing pressure differences with respect to the atmosphere before discharging the bath.  The heating may be effected <FORM:0719462/IV(c)/1> electrically, or either directly, or indirectly, by steam.  In the control system shown for bath-preparation plant comprising a mixer in which the crude bath is prepared and from which it is subsequently transferred by a steam jet pump to a steam-heated boiler, a switch 9 is first moved to its lower position to allow manual control, by switches 7, 8 of solenoid-operated valves 5, 6 which, respectively, open the boiler to the atmosphere and supply steam to the pump during the transfer operation.  After setting a timer 11 for the required boiling time, switch g is moved to its upper position and a push button switch 12 is operated to start the automatic heating operation.  Relay 13 thereby operates, holds in over the timer contacts and extends the supply to relays 15, 16 which are controlled by a thermal switch 14, 151, 161, responsive to boiler temperature, these relays then controlling the steam heating valves 6, 17 for the boiler.  At a given temperature, contact 151 opens, causing relay 15 to release, thereby starting the synchronous motor driving the timer 11 and shutting the valve 6, after which contact 161 (controlling valve 17 through relay 16) regulates for constant boiler temperature. Eventually, the timer contacts open, de-energizing relay 13, and terminate the heating process.  Simultaneously, a relay 18 releases, to open valve 5 and effect pressure equalization in the boiler. Indicating lamps 20-22 may show the condition of the plant at any stage of the process.  A recording thermometer 25, 26 may also be associated with the plant.

Title: Amalgam gun
Inventor: JOCHEMS JOSEPH ROELOF
IPC: A61C5/50
Filed: 1970-01-16
Abstract: 1294223 Amalgam gun J R JOCHEMS 16 Jan 1970 [22 Jan 1969] 2298/70 Heading A5R A device for filling a dental or other cavity with amalgam comprises a cylinder 1 connectable to a hose 2 at one end, and formed with a wall 4 and an external curved tube 3 at the other, a piston 5, movably mounted inside the cylinder 1 with a piston rod 6a, 6b, 6a being connected to a flexible rod 7 connected to a plunger 8 slidable in the tube 3, 6b being connected to a further plunger 11 slidable in a second cylinder 12 substantially coaxial with the first cylinder 1, and open to the atmosphere, as shown. The rod 6b extends through an orifice 9 in a transverse wall 10, which orifice is adapted to form a sealing engagement with the plunger 11, and a further orifice 14 is formed in the wall of the cylinder near to the wall 4. Amalgam is placed into the open end of tube 3 and compressed air fed to the piston 5 which then moves towards the end wall 4 of the cylinder thereby forcing amalgam from the tube 3 into a cavity to be filled. This movement continues until the plunger 11 enters the orifice 9, piston 5 then being to the left side of the orifice 14 as seen in Fig. 2 (not shown), through which the pressurised air in the piston space escapes. A tamping action is produced by the pressing of the end of the tube 3 against the tooth causing the plunger 8 at the end of its movement, to be pushed slightly back into the tube 3, the pressure behind the piston 5 thereby being allowed to increase. A rod 16 is connected coaxially with the plunger 11, which rod has two opposed, staggered sets of teeth adapted to cooperate with two coupled pins 19 which pins are spring loaded in one direction. The external movement of these pins 19 allows the rod to move to the left, in a stepby-step manner, as shown, by one half of a tooth pitch at one time.

Title: Sideband selecting system
IPC: H03C1/60
Filed: 1957-01-22
Abstract: 811,540. Amplitude-modulation systems. COLLINS RADIO CO. Jan. 22, 1957 [April 12, 1956], No. 2302/57. Class 40 (5). In a single-sideband modulator a switch enables either sideband to be transmitted without adjustment of any filters or change in frequency of any oscillator. To this end an audio modulation fa may be mixed with oscillations from a stable oscillator 9 (frequency say fs) in a balanced modulator 6 followed by a sideband filter 7 before mixing again with a carrier frequency fc from oscillator 14 in a second mixer 8, a filter 15 of pass-band centred round (fc + fs) selecting only a single sideband (fc + fs + fa) for transmission. Also the stable oscillator 9 is multiplied, e.g. doubled, in frequency before subtracting the multiplied frequency from the carrier frequency in a third mixer 11 to derive frequencies fc + 2fs which on being connected by switch 12, 13 to the mixer 8 produces frequencies fc Œ 2fs Œ (fs + fa), only fc + 2fs- (fs Œ fa) of which can be transmitted by the filter 15, i.e. the other sideband. Sideband filter 7 ensures that in the transmitted wave the audio frequencies form a single sideband relative to the effective suppressed carrier frequency (fc + fs).

Title: Improvements in signal mixing circuits
IPC: H03K5/24
Filed: 1952-01-29
Abstract: 700,148. Pulse mixing circuits ; valve non-linear circuits; radar. RADIO CORPORATION OF AMERICA. Jan. 29, 1952 [Feb. 3, 1951], No. 2415/52. Classes 40 (6) and 40 (7) In a non-additive mixing circuit two valves 10, 12 with loads 26, 28 and 30, 32 are arranged with a rectifier 34 between the anodes, the output being taken from one anode. The circuit is described as applied to a P.P.I. display in which range markers are fed to valve 12 and target echoes to valve 10, the output when the target and range signals coincide being less than the sum of the individual outputs so that the echo appears to pass through the range marker circle but the amplitude is insufficient to cause defocussing. By applying a D.C. bias to valve 10 pulse signals fed to valve 12 may be clipped at a desired level. Alternately a D.C. bias on valve 12 will vary the gain and degree of non-linearity for signals applied to the valve 10. By suitable choice of components, the output may be made a function of the two inputs. Circuit operation.-The rise in anode potential due to negative-going echo signals applied to valve 10 causes rectifier 34 to cut off so that the output circuit is isolated from valve 12 and its load. The application of negative-going marker signals to valve 12, in the absence of echo signals causes the anode potential to rise maintaining rectifier 34 conducting so that the anode load is shunted by the circuit associated with valve 10, output signals being fed over the rectifier 34 to the grid of the C.R.T. When both echo signals and range markers occur and the relative anode potentials are such as to maintain the rectifier 34 conducting both valves feed into a reduced load so that the output is less than the arithmetical sum of the two signals applied separately. When used as a clipper with a D.C. bias on valve 10 the base of the negative-going pulses applied to valve 12 are ineffective. The rectifier 34 may be a crystal diode and may be biased.

Abstract: 397,872. Reproducing music ; phonographic recorders. TEYTE, M., Woolley Grange, Maidenhead, Berkshire. Jan. 29, 1932, No. 2690. [Class 40 (iv).] In order to avoid distortion in recording or amplifying speech or song by electrical means due to such means effecting amplification according to the intensity of the sound rather than the actual or audible loudness, a visible record of the characteristics of sound waves representing variations of loudness is made, and this record is used in association with the written or printed speech or music to enable the artiste to control the sounds so as to avoid or reduce distortion in the record to be made or in the sound to be reproduced in the usual way. The record of the loudness characteristics is suitably made by electrochemical means on a strip 20, Fig. 2, moistened with a solution of starch and potassium iodide through a wick 24, by a marker 12 oscillated by an arm 10 from a rectangular coil 6 which oscillates within the permanent magnet 7 due to the current fed through the coil from a recording or transmitting microphone 1, Fig. 1, influenced by the sounds and connected with the coil through an amplifier 2, valve 3, and full wave rectifier 5. In order that the recorded trace may be recorded of loudness as distinguished from intensity, the movement of the coil 6 within the magnet 7 is so restrained that the movement of the coil and consequently of the marker, is proportional to the logarithm of the restraining force. Fig. 3 shows a means to effect this, the oscillation of the coil being restrained by springs 16, 17 attached to cams 14, 15 attached to the coil and suitably shaped. The record may be placed adjacent to the corresponding score of the music sung by the artiste to facilitate control of the intensity of production of sound.
