Abstract: 919,236. Mounting electrical components on circuit boards. PLESSEY CO. Ltd. July 18, 1960 [June 8, 1959], No. 19570/59. Class 83 (2). Apparatus for mounting electrical components on circuit boards comprises an element arranged to move cyclicly in a predetermined path and to engage and turn over the ends of the lead wires of a component during each cycle so that the ends extend along predetermined directions of the board. Mounting plates 1 and 2 connected by spacers 3 carry shafts 13, 14 adapted to be driven from a motor 6 through spindle 9 and a common gear 10. The upper ends of the shafts carry eccentrics 27, 28 respectively on which a rectangular plate 29 is mounted by way of bearings 30, 31 so that when the shafts rotate the plate moves in a circular path. Mounted on the plate 29 is another plate 29A having a number of through bores 41c, 42c ... related to the positions of the holes 41a, 42a in the circuit board 40 which is fixedly mounted just above the plate 29A. In operation, the leads of a component are pushed through the appropriate holes in the circuit board and during a cycle of the plate 29A become aligned with and enter the bores therein. Further movement of the plate 29A bends the ends of the leads along the underside of the conducting strips of the printed circuit. The bending of the leads at the correct angle is ensured by the relationship of the bores 41c, 42c ... to the holes 41a, 42a ... The position of the bores is found by marking centres 41b, 42b ... on the plate 29A vertically below the holes 41a, 42a, marking circles of equal diameter around these centres and then drawing lines from the centres in the direction of the conducting strips of the printed circuit. The points of intersection of the lines and the circles give the correct positions for the bores 41c, 42c... The circles have a diameter equal to or slightly greater than the eccentricity of the shafts 27, 28.

Title: Process for separation of mixtures of high molecular synthetic alcohols into components of different melting point
Filed: 1951-08-27
Abstract: Mixtures of synthetic alcohols containing at least 8 carbon atoms are separated into components of different melting-point by allowing the partly or completely melted mixture to solidify incompletely and separating solid and liquid components by pressing.  Organic solvents, containing 1-11 carbon atoms, e.g. hydrocarbons, their halogen derivatives, alcohols, esters, and ethers, if desired containing water, may be present in amounts of up to 15, generally only a few per cent.  Using mixtures of not too wide boiling range, straight chain, and branched alcohols of different degrees of branching may be separated.  Pressing is effected in an ordinary press, usually at a temperature not substantially below normal.  The liquid fraction may be further cooled to separate solid.  Products of fatty acid reduction, Oxo syntheses or carbon monoxide hydrogenation may be separated to give alcohols for use in the lubricants, textile, detergent, cosmetic, and like industries.  In examples: (1) a C18 average fatty alcohol mixture is heated to 70 DEG  C. and slowly cooled for 12 hours, the solid cake about 3 cms. thick being wrapped in a filter cloth and pressed at 17 kg./cm.2 at 20 DEG  C.; (2) a C16-C28 mixture is melted and slowly solidified to a 5 cm. cake which is pressed at 20 DEG  C. and 50 kg./cm.2; (3) the mixture of (1) is melted and treated with 5 per cent of methanol, ethanol, benzine, C6-C9 fatty acids, acetone or glycerol monomethyl ether, cooled, and pressed at 24 DEG  C. and 34 kg./cm2.

Title: Improvements in or relating to electric signalling systems
IPC: H04J3/00
Filed: 1951-08-28
Abstract: 705,946. Multiplex pulse signalling. GENERAL ELECTRIC CO., Ltd., ASPIN, J. J. E., BRYDEN, J. E., RUSSELL, C. R., and STENNING, L. C. Aug. 11, 1952 [Aug. 28, 1951], No. 20277/51. Class 40 (5) In an electric signalling system, the main intelligence is converted into a modulated pulse train which is transmitted by shifting the frequency of a carrier wave ; and additional signals, which may be for supervisory, monitoring, and like purposes, are transmitted by modulation of the amplitude of the same carrier wave. Fig. 1 is a diagram of a transmitter, and a co-operating receiver. The signal-modulated pulse train from a source 1 shifts the frequency of a low-frequency generator 2 the output of which is mixed at 4 with oscillations from a high-frequency source 3, either the sum or the difference frequencies being passed through an amplifier 5 to the aerial 6. The additional signals are applied from their source 7 to the amplifier 5 to modulate the amplitude of the outgoing wave. The additional signals may be amplified before being applied to the anode circuit of the carrier amplifier 5, Fig. 3 (not shown). At the receiver, the incoming wave is converted to an IF wave by the local oscillator 12 and mixer 11 and after amplification at 13, 14 is passed to an AM detector 18 to provide the additional signal at 19. The amplified IF output is also passed through a limiter 15 to a frequency discriminator 16 which yields a signalmodulated pulse train conveying the main intelligence. In Fig. 4 the IF amplifier 14 comprises pentode valves 41, 42 and a germanium detector 43 with load resistor 44. The detected AM signal is fed through a cathode follower stage 45, 47 and coaxial cable 48 to a filter 51, amplifier 52, output transformer 53 and a telephone instrument. A a relay station, Fig. 2 (not shown), the pulse modulated main signal, instead of being detecte by the discriminator 16 of Fig. 1, is fed from th limiter 15 to a mixer unit where it is raised in frequency by a local h.f. source, passed to a power amplifier and radiated. The additional signals from the receiver 19, together with any desired locally-produced additional signals, are fed to the power amplifier to impose an amplitude modulation on the output.

Filed: 1926-08-17
Abstract: 265,078. Tugwood, R. J., (Daimler Motoren Ges.). Aug. 17, 1926. Ink-ribbon mechanism. -In automatic feed-reversal mechanism for ink ribbons of the kind in which reversal is initiated by axially movable pins in the spool spindles, two interconnected constantly oscillating levers are each provided with a pair of racks co-operating with a ratchet-wheel on the associated spool spindle, engagement and disengagement of the racks and ratchet-wheel being controlled by the axially movable pin. Levers l, p interconnected by a sliding rod o are provided with pairs r, s and v, w of racks connected by springs t, x and co-operating with ratchet-wheels u, y on the spool spindles c, the lever l being oscillated by a heart cam h driven by a bevel wheel f. The racks are formed with inclines abutting on pins 11 carried by levers 7 rocking on the pivots m, q of the levers l, p and interconnected by a sliding rod 9 arranged in the rod o. The pins maintain one pair of racks in engagement and the other pair out of engagement with the associated ratchetwheels. Each pair of racks is so arranged that when in engagement with the ratchet-wheel, feed is affected alternately by the two racks during the backward and forward movements of the levers l, p. The spool spindles are each provided with an axially movable rod 1 normally held up by a lever 4 engaging the coiled ink ribbon. When the ink ribbon has been wound off either spool the rod 1 of that spool drops and enters a slot 6 in the associated lever 7 so that during the following oscillation of the levers l, p the levers 7 are rocked relatively thereto and the pins 11 effect engagement and disengagement of the racks of the full and empty spools respectively, the feed being thereby reversed. The ink ribbon thereupon winds on the empty spool and causes the lever 4 to raise the depressed rod 1. The rod 9 may have a pin 12 which passes through a slot 13 in the rod o and by its position indicates on to which spool the ink ribbon is being wound.
