IPC: F23Q2/16
Filed: 1959-02-10
Abstract: 887,471. Gas-filled lighters. WALL Ltd., HOWARD. May 9, 1960 [Feb. 10, 1959], No. 4651/59. Class 75(3) A smoker's lighter comprises a gas valve 26 biased to open position by a spring 27 and means to close the valve when the finger-piece 1 for operating a cover 2 and a flint wheel 3 is released. When the finger piece 1 is depressed against the action of a spring 22 a pin 31 on the finger piece 1 moves out of engagement with one end of a lever 28 pivoted at 29 and having its other end abutting a collar 30 on the gas valve 26. The lever is thus free to pivot and to allow the valve 26 to open. In another embodiment the pivoted lever is replaced by a slide which slides on the top of the lighter and has a cam face engaging with the collar on the gas valve. The finger piece has a pin which engages in an inclined slot in the slide so that depression of the finger piece causes sliding movement of the slide to allow the gas valve to open. The gas may be led to the gas valve by a wick held at its end between absorbent paper discs and the pressure on the discs can be regulated by a screw to control the size of the flame.

Title: Improvements in routers
Inventor: MANN THEODORE CHARLES
IPC: B23Q35/10
Filed: 1953-02-26
Abstract: 721,088. Copy-milling. EKSTROM, CARLSON & CO. Feb. 26, 1953, No. 5399/53. Class 83 (3). A router for copying work 26 from a template 25 comprises a milling cutter 23 and a follower 24 mounted on the free end of an outer arm 21 pivoted to an inner arm 15 pivoted on the base 16, and power actuators 28, 29 act simultaneously on the arms under the control of a manual selector 58 to swing the arms to produce a resultant force, approximating in direction to the manual force of the operator in a hand-fed router, which moves the follower round the template. The actuators may be electric or fluid-pressure reversible rotary motors or, as shown, fluid-pressure jacks 36, 45. High-pressure fluid is supplied to a selected jack while low-pressure fluid is supplied to the other jack so that a larger component of the resultant force feeds the tool through the work and a smaller component holds the follower on the template. The selector 58 has a control handle 60 on a ball-and-socket joint 62 which can be tilted to or from the operator or sideways in cross slots 64 to operate one or other of four switches 66 positioned at 90 degrees to each other and energizing, through relays, different combinations of solenoids S1-S6 on valves 75, ... 77 in the hydraulic system. The valve 75 functions to direct high-pressure fluid from a pump 54 to a selected jack 36 or 45 and low-pressure fluid from a pump 55 to the other jack, and the valves 76, 77, selectively direct the fluid from the valve 75 to one or other end of, respectively, the jacks 36, 45. Both jacks are preferably mounted on the inner arm and the jack 36 has a double rack-and-pinion drive 39, 42 to a gear 43 fixed on the inner arm pivot, and the jack 45 has a single rack-and. pinion drive 47, 50 to a gear 52 fixed on the outer arm 21. For rapid traverse of the tool from the finishing point of a cut to a new starting position, additional high-pressure fluid from a pump 120 is directed by a solenoidoperated valve 119 to the high-pressure cylinder, as selected by the handle 60, and the lowpressure fluid to the other cylinder is by-passed to the sump 84 through lines 126 or 138 and the valve 119. The rapid traverse is initiated by depressing a push rod 132 in the control handle so that a button 135 closes a switch 136 in the circuit of the solenoids of the valve 119 and the button at the same time closes another switch 137 so that a solenoid-operated valve 112 is moved to a position in which fluid from a pump 111 is supplied to a jack 106 to raise the cutter-head clear of the work. The head may also be raised and lowered on its ways 110 by depressing one of a pair of push-button switches in the circuit of the solenoids SL, SR, its downward movement being limited by stop nuts 118 on a rod 115 engaging a bracket 117 on the arm 21. A single motor 87 drives the four pumps,

Title: Method of preparing the mono-carboxylic acid derivative of an aldehyde not susceptible to the cannizzaro reaction
IPC: C07C47/56
Filed: 1945-03-05
Abstract: The mono-carboxylic acid derivatives of o-vanillin, p-vanillin, or syringaldehyde are obtained by treating the aqueous aldehyde with excess alkali and with a finely-divided oxide of either silver or gold at a temperature of not less than about 50 DEG  C. Advantageously, two mols. of the aldehyde are treated with two mols of alkali and one mol. of oxide.  In an example, an aqueous solution of silver nitrate is treated with aqueous sodium hydroxide to obtain freshly precipitated silver oxide for use in the subsequent oxidation of p-vanillin which is effected in the presence of excess aqueous caustic soda at a temperature of not less than about 50 DEG  C.  The precipitate of pure silver is filtered off and the filtrate is acidified with sulphur dioxide to precipitate the monocarboxylic acid derivative.  Gold sesquioxide may be used instead of the silver oxide.  The Specification as open to inspection under Sect. 91 generalises the aldehyde starting materials to those not susceptible to the Cannizzaro reaction.  This generalisation does not appear in the Specification as accepted.
