Title: Interference reducing in electric pulse signalling systems
IPC: H03K9/00
Filed: 1945-07-20
Abstract: 593,511. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. July 20, 1945, No. 18709. Convention date, Nov. 23, 1943. [Class 40 (v)] To reduce the effect of interference at a receiver, only pulses of the signal pulse width are passed, dummy pulses being substituted for the suppressed pulses to reduce hum. The dummy pulses may be modulated to improve the demodulated output. The input is applied to a pulse width discriminating circuit 12, which may be of the type described in Specification 592,789, the positive pulse output feeding a clipper amplifier 32. The right triode of valve 52 operates as a blocking oscillator, synchronized by a positive pulse on the anode, due to the negative-going pulse from amplifier 32 cutting off the left triode of valve 52. In the absence of an interfering signal, the blocking oscillator is synchronized from the signal pulses, producing output pulses which are fed to the demodulator. With interference when a signal pulse may not appear, the blocking oscillator runs at its natural frequency to supply a dummy pulse. The input signal may also be fed to a clipper amplifier 72, giving an output when a signal and interfering pulse overlap, the output being applied to the left triode of valve 52 to synchronize the blocking oscillator so that the output pulse is modulated. The blocking oscillator may be replaced by a multivibrator.

Title: Apparatus for applying solder paint to the seams of cans and other articles
IPC: B23K1/16
Filed: 1950-07-28
Abstract: 678,332. Soldering. TAYLOR, G. March 27, 1951 [July 28, 1950], No. 18860/50. Class 83 (iv). Apparatus for applying solder paint to the seams of cans &c. comprises a trough for solder paint and a reciprocating blade adapted to be moved down to convey the solder paint through an outlet slot on to the seam, the said slot normally being closed by an angularly-movable member which is retracted to open the slot during the downward movement of the said reciprocating blade. A block 1 has a bore 3 for receiving one end of a mandrel 4 carrying detachable cylindrical collars 6. A can 7 is placed over the collars and its seam 7a is located by aligned recesses 8 in the collars. A hopper-shaped container 10 extends above the mandrel and has side walls 11, 12 connected by end walls 13, 14, having extensions 13a and 13b. The container is adjustably secured to the block 1 by screws 15 and 17. A pin 21 mounted between the end walls 13, 14 carries a hinged wall 22 of a hopper-shaped trough 23 for the solder paint, the other wall of the trough being formed by the wall 12 of the container. The wall 22 is divided into separate hinged plates 22a to 22e and a spring 24 ensures that the lower edge of each plate is normally closely engaged with the lower edge of the wall 12 of the trough. Inside the trough 23 and slidable between ribs 26 on the wall 12 is a vertically reciprocating blade holder 27 carrying a blade 31. The length of the blade corresponds to the number of hinged plates which make up the length of seam to be soldered. The blade holder is reciprocated by a treadle (not shown) which actuates a rod 32 pivoted to an arm 34 secured to a rock-shaft 35 carrying a pair of rocker-arms 36 which engage the blade holder. A spring returns the blade holder to its normal position when the treadle is released. On its downward movement the blade pushes back the hinged plates and forms a slot 25 through which the blade passes and conveys the solder paint 45 on to the seam. The can is then removed and heated either electrically or with gas jets and when the solder reaches melting point an air blast may remove the ash caused by burnt flux so leaving a neatly soldered joint. The solder paint, which comprises a fluid mixture of powdered solder and solder flux, is agitated by ribs 42 on the blade holder 27. The trough wall 22 may be partly hinged and partly fixed and the hinged part need not be divided into sections. The apparatus may be used for applying solder paint to the inside seams of cans in which case the cans are arranged to fit over the trough. In an embodiment, the container 10 and mandrel 4 are carried by a hollow cast-metal pedestal 46, Fig. 5, having a base 47 to which is pivoted a pedal 48 connected to the rock-shaft 35 by a rod 49 and arm 50. The upper part of the pedestal forms a storage reservoir 51 for the solder paint and communicates with the trough 23 by means of a tap 54.

Abstract: 1407764 Photo-electric fluid analysis TECHNICON INSTRUMENTS CORP 24 April 1973 [7 June 1972] 19430/73 Heading G1A Fluid samples 5, Fig. 1A, such as blood are passed through a flow cell and are separated from one another by a separating fluid SF, such as air; a light source 12 and detector 18 measure the light transmitting properties of the cell and the fluids therein. The output of the detector is periodically sampled at a rate high enough to ensure that for each group of n samples at least one corresponds to the state where the whole of the light path of the cell is occupied by the fluid S to be analysed (as shown in Fig. 1A). The separating fluid forms a meniscus with the fluid S, so that when any of the separating fluid is in the light path there will be a loss of light due to reflection and refraction at the meniscus; consequently the signal from the detector is greatest when the cell is occupied only be fluid S and there is no meniscus. A sample and hold circuit, Fig. 1B (not shown) serves to establish which of each group of n samples of the detector output is the greatest, and this is a measure of the concentration of the sample S to be analysed.
