Title: Products containing sulphonated halogen derivatives of aliphatic alcohols
IPC: C07C305/00
Filed: 1933-04-19
Abstract: Saturated aliphatic alcohols containing more than eight and not more than eighteen carbon atoms in the molecule, or mixtures thereof are halogenated, whereby their melting point is lowered and then treated with sulphonating agents which do not contain imino or amino groups to convert them into sulphuric acid esters. In examples, (1) cetyl alcohol is chlorinated in carbon tetrachloride, and sulphonated with chlorsulphonic acid after removal of the solvent; (2) the mixture of alcohols obtained by reduction of coco-nut oil acids is chlorinated and similarly sulphonated.  By halogenating the alcohols, the solubility of the sulphonated products is increased without impairing their wetting properties.  Specification 400,986 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the halogenation and sulphonation of unsaturated alcohols and in additional examples, a mixture of cetyl and oleic alcohols, octodecanediol and beeswax alcohols are chlorinated and sulphonated. This subject-matter does not appear in the Specification as accepted.

Title: Regulated power supply
IPC: G05F1/59
Filed: 1975-03-20
Abstract: 1498112 Constant voltage supply with over-current protection LANDIS TOOL CO 20 March 1975 [25 March 1974] 11782/75 Headings H2H and H2K A power supply adapted to maintain a constant voltage across a variable load 28 comprises a voltage regulator 21 adapted to handle currents less than a predetermined amount, e.g. 1 amp, at least one by-pass current path 31, 33, Q2 connected in parallel with the regulator 21 for by-passing current of a magnitude at least equal to the difference between the total current of the circuit and the maximum regulator current when the total current is less than a predetermined value, and means for directing all of the current to the regulator 21 when the total current exceeds the predetermined value resulting in the regulator operating in a current limiting mode. As shown, power from an A.C. source is rectified at 11, 12, filtered at 13 and passed to load 28 via regulator 21 which keeps the voltage across the load constant, a signal controlling the regulator 21 being derived across resistor 25. A first by-pass path 32, 33, Q2 is in parallel with the regulator 21, transistor Q2 being controlled by basebias resistor 36 and in-turn controlling transistors Q3, Q4 in two further by-pass circuits as shown. In operation, when the current through the load is less than a particular value, the by-pass circuits carry all the current in excess of the maximum regulator current. If the current through the load exceeds this particular value, a further transistor Q1 is turned on by the voltage drop across resistor 31, which then shorts the transistor Q2 and turns each of transistors Q2-Q4 off. All the current is then passed through regulator 21 which causes a thermal cut-out to operate and the voltage across the load to fall away, the regulator then only transmitting a trickle current. A voltage sensitive device 42 then causes opening of relay 17, 18 to switch off the supply. An overvoltage protection device is also included. When the voltage across the load 28 exceeds a predetermined value, transistor Q5 conducts and causes thyristor 51 to be triggered. The shorting out of the load 28 causes device 42 to operate relay 17, 18.

Abstract: 472,922. Wireless receiving circuits. COLE, Ltd., E. K., and HUNT, H. April 29, 1936, No. 12120. [Class 40 (v)] The tuning knob of a radio receiver controls the application of muting potential to the grid of a valve, the bias being removed when the knob is released. Depression of the tuning knob first closes contacts A, B which earths the grid circuit of the power amplifier V2 and then closes contacts B, C which applies a heavy negative bias to the low-frequency amplifier V1, derived from a resistance 2 shunted across the field coil 3 of the loud-speaker. The knob is then rotated to tune in the desired station, and when released the blocking bias on V1 leaks away across a 2-megohm resistance R. V2 is first muted to prevent a loud click when V1 is muted. A visual tuning indicator is preferably used to facilitate accurate tuning while the receiver is muted.

[Class 44] In lock mechanism of the kind in which a detector lever co-operates with a spring which engages a detent on the lever to hold the latter in locking position on the use of a false key or a. pick lock, the detector lever c, Figs. 1 and 4, has a detent nose e<1> adapted to engage behind a spring tongue f mounted in the tail of the locking bolt b when the latter is in its advanced position and the lever is angularly moved beyond its unlocking position, as shown in Fig. 4. The spring f, Fig. 5, is mounted in a slot in the tail-plate b<1>, and has a laterally off-set nose f<1> to engage the detector lever. The detector lever also carries a pin g, Figs. 1 and 4, which extends across the edges of all the other levers, so that if any of these are moved beyond unlocking position, the lever c is correspondingly moved. Engagement of the detent nose e<1> with the spring f prevents withdrawal of the bolt b, and since the nose c<1> is undercut, the lever c is held in its over-lifted position, so that the lock cannot be operated normally, even with the correct key, but must first be brought back to normal position by turning the correct key in locking direction, thus advancing the bolt slightly and disengaging the spring f from the nose c<1>.

Abstract: 703,247. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. May 18, 1950, No. 12451/50. Drawings to Specification. Class 40 (5) A pulse train, comprising a plurality of interlaced channel pulse trains, frequency modulates a carrier wave which is periodically interrupted at the channel pulse recurence frequency to provide synchronizing signals. In the transmitter described, a delay line distributer provides channel pulses which are subsequently amplitude modulated, combined and used to frequency modulate a carrier. The distributer also produces synchronizing pulses which are used to block an amplifier between the modulated carrier source and the output stages of the transmitter, Fig. 1 not shown). At a receiver adapted to select any one channel signal, a carrier rectifier provides a pulse for each gap in the incoming carrier wave, the pulse being passed through a delay device having suitable manual settings, to unblock a normally blocked amplifier preceding the discriminator circuit at times appropriate to the channel pulses selected, Fig. 2 (not shown).
