Patent GB-828591-A (GB)
Title: Novel bicyclic compounds and a process for the manufacture thereof
IPC: C11B9/00
Filed: 1958-05-21
Abstract: The invention comprises 1-hydroxy-naphthalenes of the formul <FORM:0828591/IV (b)/1> <FORM:0828591/IV (b)/2> and esters thereof and 1-keto-naphthalenes of the formul  <FORM:0828591/IV (b)/3> <FORM:0828591/IV (b)/4> <FORM:0828591/IV (b)/5> where R1, R2 and R3 represent optional alkyl groups containing up to six carbon atoms (the broken lines denoting the optional bonds thereto).  The preferred compounds are those in which R1, R2 and R3 are absent, i.e. the 2,5,5,9 - tetramethyl substituted compounds.  The compounds may be prepared by a process which comprises or includes as a first step treating an aldehyde of the formula <FORM:0828591/IV (b)/6> with an acidic agent to give the unsaturated alcohol I.  The alcohol I may then be treated by methods known per se for the purposes of esterification, isomerization, hydrogenation of the double bond or oxidation of the hydroxyl group and one or more such operations may be carried out in any order.  The cyclization of the aldehyde preferably takes place in the presence of phosphoric acid and in the absence of any solvents, the acidic agent may, however, be formic or acetic acid in which case the appropriate ester of alcohol I is directly obtained. Esterification of the alcohols may be carried out using acid halides or anhydrides in the presence of pyridine, hydrogenation of the double bond catalytically in the presence of palladium, oxidation of the hydroxy group with chromic acid in acetic acid, isomerization at the double bond of the unsaturated ketone by means of sulphuric acid and isomerization of the alcohol at the hydroxy group by oxidizing it to a keto group and then reducing the ketone with lithium aluminium hydride.  In the examples: (1) 4 - [21,61,61 - trimethyl - cyclo - hexen - 11 - yl] - 2 - methyl - butanal - 1 is cyclized to give 2,5,5,9 - tetramethyl - 1 - hydroxy - 1,2,3,5,6,7,8,9-octahydronaphthalene and its esters are prepared with formic, acetic and benzoic acids; the unsaturated alcohol is reduced to the corresponding saturated alcohol (type II) which is in turn oxidized to the saturated ketone (type V), hydride reduction of this ketone gives a saturated alcohol isomeric with the one mentioned above; the unsaturated alcohol (type I) is oxidized to the ketone (type III) which is isomerized to ketone (type IV) and then reduced to a saturated ketone (type V) which is isomeric with the one mentioned above; (2) and (3) the formate and acetate esters of the unsaturated alcohol (type I) above are directly prepared by cyclizing the aldehyde in the presence of formic and acetic acids.

Title: Improvements in signalling devices for motor road vehicles
IPC: B60Q1/50
Filed: 1946-05-30
Abstract: 623,089. Road traffic signals on vehicles. HAVERS, SIR E. W. May 30, 1946, No. 16468. [Class 118 (ii)] A motor road-vehicle signalling system is operated in two stages of which the first comprises the movement of a semaphore arm or the illumination of a representation of a suitable symbol and the second comprises the illumination of the arm, or the movement of an element articulated thereto, or the extinguishing of part or all of said representation and the simultaneous illumination of an adjacent part or whole representation to give the illusion of movement of the representation. When a driver, in response to a signal, has overtaken another vehicle he moves a switch c to position a to raise a semaphore-type direction indicator and then either depresses the switch c or moves it to a further position a<SP>1</SP>. This has the effect of illuminating a suitable inscription or other symbol on the arm or moving a model hat, arm, or thumb, mounted thereon, in order to acknowledge the courtesy shown by the driver being overtaken. The control switch c may in positions a and b operate a normal direction indicator arm and when depressed light the panels d and e, Fig. 2, of a sign representing a man the illumination of the panel e fading after a short interval and the panel f being illuminated. The successive illumination of panels e, f may be accomplished by manual or thermostatic switch means. Other symbols may be similarly illuminated. In combination with the visual courtesy acknowledgement there may be provided an audible signal which may take the form of two horn notes or the reproduction by known means of spoken words, a peal of bells, or a tune.

Three beryllium copper wires 23 having a diameter of 5-20 mm., which comprise a contact brush 40 are cut from a wire coil and mounted on a base 100 having a radiused face 104 equivalent to the radius of the wire coil. The base comprises two parallel slots 106 which house metallic or metal coated post members 114 retained by screws 120 and flush with the face 104 and a pair of slots 108 which house aligned aluminium guide members 110. The wires 23 are located side by side in the slots 112 of the members 110 with their ends overlaying the post members 114. Solder is applied to each end of the assemblies to solder each group of three wires together and to the post members 114 and during the operation solder is caused to run up the contact wires to the slots 112 to retain the wires together. The post members 114, and the attached soldered bush sub-assemblies are subsequently removed from the base 100 and transferred to a bending die 200. The die comprises retaining clamps 206, an inverted V- shaped central section bounded by inclined surfaces 214 and guide pillars 202 on which an upper member 204 having a complementary configuration is fitted. The sub-assembly is retained in position by clamping the post members 114 to the side of the die 20 and the sets of brushes 40 are permanently deformed between the dies to form a centrally positioned V. The contact brushes are removed and fitted into shallow grooves formed in the end surfaces 34 of the edge portions 28 of a contact carrier block 22. The grooves are approximately three diameters wide and one diameter deep and the wires are retained by a suitable non-conducting epoxy resin adhesive which also secures a coverplate 29 placed over the protruding V portions of the brushes to the assembly. Finally the metal support posts 114 are cut from the ends of brushes along the line 240 to separate each brush.

IPC: F41A17/60
Filed: 1931-06-09
Abstract: 380,441. Drop-down guns. DELU, F., 12, Rue Cesar Franck, Liege, Belgium.- (Assignee of Delu, E.; Novara, Italy.) June 9, 1931, No. 16791. Convention date, Feb. 27. [Class 119.] Double-barrel drop-down sporting guns of the kind in which each sear 2, Fig. 1, and its associated trigger 3 are movable together as a single member have the sear members displaced laterally with respect to the trigger members so that the sears are in the planes of their associated tumblers 4 whilst the triggers lie substantially in the middle plane of the gun. The sear 2 is secured to its trigger 3 by a screw 3a, Fig. 2, or these two parts are made in a single piece. The invention is shown applied to a gun in which the tumbler is cocked against the action of a spring 5c when the gun is opened. The spring bears against a member 5 formed with projections 5d, 5b on opposite sides of the tumbler pivot 4a. The member 5 is connected to the tumbler by spring-controlled links 5g which move the tumbler into engagement with the sear 2. When the sear is released the member 5 presses with its projection 5b on the tumbler and fires the gun, the inertia of the tumbler causing it to move against the projection 5d and rebound within the action body. The Specification as open to inspection under Sect. 91 (3) (a) also describes (1) modifications of the cocking and rebound mechanism, in which a cocking lever 8, Fig. 7 (Cancelled), acts directly on the tumbler to cock it against the action of a V-spring 5c which also acts to cause the tumbler to rebound ; (2) safety mechanism combined with the looking-bolt 9 ; (3) a spring button 15c, Fig. 3 (Cancelled), permitting ready withdrawal of the top-lever axis pin 14 ; and (4) a form of action body and means for attaching it to the stock by a longitudinal screwed rod 13a.
