Title: Improvements in or relating to methods of treating caschew nut shell liquid and the products obtained thereby
IPC: C07C37/00
Filed: 1934-12-18
Abstract: A phenol of the formula <FORM:0452413/IV/1> , in which the C14H27 residue is in the meta-position to the hydroxyl and comprises a straight chain containing a double bond between the 7th and 8th carbon atoms, is prepared from cashew nut shell liquid by heating the liquid to its boiling-point under atmospheric or reduced pressure and collecting the distillate coming over at about 360 DEG  C. at atmospheric pressure or a correspondingly lower temperature at the reduced pressure. Alternatively, the fraction coming over at 310--398 DEG  C. at normal pressure is redistilled under 10 mm. and the distillate at 225 DEG  C. collected; or the liquid is steam distilled at atmospheric pressure and the product collected which comes over at about 270 DEG  C.  The product may be purified by distillation at about 225 DEG  C. under 10 mm.  The cashew nut shell liquid is preferably obtained by solvent extraction of the shells at a low temperature, e.g. with benzene at ordinary temperature and by brief immersion of the shells in cashew nut shell liquid maintained at 165 DEG  C.  The liquid obtained may be freed from darkening compounds by washing with water, or by heating with sodium perborate, or by blowing with air or oxygen or hydrogen, preferably in the presence of alkali.  The phenol may be reacted with a reactive methylene compound, such as formaldehyde, paraformaldehyde or hexamethylenetetramine, or heated with paint and varnish driers, such as manganese resinate, litharge, cobalt acetate or copper oleate.  It may also be used as a plasticizer for cellulose esters. Specification 300,654, [Class 2 (iii)], is referred to.

Title: Improvements in or relating to electric telegraphy and like signalling systems
IPC: H04L25/49
Filed: 1928-12-11
Abstract: 326,501. Telford, A. E. Dec. 11, 1928. Type-printing telegraphs.-In a type-printing telegraph system having synchronously moving apparatus at transmitter and receiver, signalling is affected with a single key, the first depression of which starts the receiver which continues to move until arrested, with the desired character in the printing position, by a second depression of the key. The type-drum 2 at each station is rotated step by step by a magnet 8a, the circuit of which is closed by an interrupter 8m driven by clockwork 12 released by the first signalling impulse. The first depression of the key 7 at the transmitter closes a line circuit through the relays 14a at each station, thereby closing local circuits for the magnets 5a, 9a, 15a. Each magnet 5a moves a stop 5 out of the path of a pin 6 on the drum 2, and the magnet 15a starts the interrupter 8m to rotate the type drum. When the desired character appears beneath an aperture at the transmitter, the signalling key is again depressed, and the magnets 5a, 9a, 15a are again energized, the magnet 9a causing a stop 9 to arrest the type-drum and effect printing by pressing the tape 3 against the type. A further letter or letters may be printed by further depressions of the key provided they come into the printing position before the pin 6 again engages the stop 5, thereby arresting the type drum. The message is recorded at both stations.

Title: Improvements in suspension means for a drive axle for a vehicle
IPC: B60G11/52
Filed: 1938-12-19
Abstract: 523,955. Vehicle spring-suspensions. HALTENBERGER, J. Dec. 19, 1938, No. 36944. Convention date, Dec. 18, 1937. [Class 108 (ii)] A motor vehicle suspension means for a drive axle includes a frame 10, a Hotchkiss type power rear axle carrying driving wheels and having a torque tube, forwardly extending distance rods 27 between the axle and frame, a connection having a radially disposed yielding line 30 to provide means of yielding torque transfer positioned between the distance rods and axle, and coil springs 35 between the wheels and the frame. In Figs. 1, 2 and 3 the frame 10 is directly supported at each side by a coil spring 35 resting on the casing 13 of the driving shafts 17. The spacings between the coils of the springs vary, so that compression takes place at a variable rate. The frame is transversely positioned relatively to the wheels by a transverse rod 23 which is pivotally connected through a rubber lining to a brake anchor-plate 18 and to the frame cross-member 12. The frame is longitudinally positioned by longitudinal radiusrods 27 which are resiliently pivoted at 25 to the frame and are connected to the axle with the interposition of pairs of rubber thimbles 30. In Fig. 4 (not shown) the application to swinging half-axles is indicated.. In Fig. 5 (not shown) the radius rods 27 are extruded to support the coil springs behind the axle, and in lieu of variable coil-spacings the coils are embedded in rubber.

Title: Improvements in methods and apparatus for the electrolytic shaping of electrically conductive bodies
IPC: C25F3/12
Filed: 1955-12-28
Abstract: 803,887. Cutting metals electrolytically. WESTERN ELECTRIC CO., Inc. Dec. 28, 1955 [Dec. 31, 1954], No. 37105/55. Class 41. A method cutting a conductive body 11, e.g. a germanium bar, comprises mounting a thin electrode, e.g. a wire 12, sufficiently rigidly to retain its shape, mounting the bar 11 near a thin edge of the wire 12, flowing electrolyte 18 along the edge in contact with the bar 11 in an amount limited to that which can be sustained between the bar 11 and wire 12 by adhesion and surface tension, passing an electric current between the wire 12 as cathode and the bar 11 as anode, and maintaining during cutting a gap between the edge of the wire 12 and the face 23 of the cut 20 in the bar 11. In one embodiment, the bar 11 is of constant cross-section and is advanced at a uniform rate towards the wire 12, e.g. 3.3 mil. tungsten wire, supplied with electrolyte 18, e.g. a 0.002 per cent by weight potassium hydroxide solution in water, through a tube 16, the wire 12 being rigidly held under tension between arms 13, 14 of a support 15. The gap between the wire 12 and the face 23 of the cut 20, Fig. 3, tends to be held constant by the non-linear inverse relationship between etching current and gap width. A constant voltage source 19 is employed. If the body to be cut has a varying cross-section, the rate of advance of the body and/or the value of the etching current may be adjusted to maintain a constant gap width. The gap should be less than twice the wire diameter. In the specific embodiment mentioned above a constant current of 28 milliamps was supplied and the bar 11 was advanced at 6.5 mils. per minute to make a cut 7 mils wide. The temperature and composition of the electrolyte should be kept constant, and the electrolyte should be of low concentration. For cutting germanium, weak aqueous solutions of alkali hydroxides, hydrochloric acid, sulphuric acid and potassium chloride or nitrite may be used. The wire electrode may be inclined to the horizontal, and the electrolyte may be delivered at such a speed, e.g. 225 cms. per second as to remove gas bubbles from the cut. In a modification, Fig. 5, two metal sheet electrodes 60, shaped to produce a cut of predetermined contour, are insulated on each face at 61, e.g. with ethyl cellulose, leaving operative etching faces 62, electrolyte being supplied at 63. Cuts of large curvature may be produced by moving the body along a non-linear path, and simultaneous cuts may be made by a plurality of electrodes staggered in the cutting direction. Specification 790,922 is referred to.

The connector of the parent Specification is modified in that the bent-over portion of each contact 6 has a U-shaped projection 12 whose crest engages the wall 9a of a recess 5, so preventing rolling of the contact portion down the wall 9a and resulting in a more constant contact pressure on an inserted printed circuit panel 3 (curve A compared with curve B, Fig. 3, not shown). Also, instead of engaging the entire length of the innermost wall 9 of its recess 5, each contact 6 engages it in one region only by a pair of lugs 8, resulting in a sharper increase in contact pressure on initial insertion of the panel 3. The contacts 6 terminate in posts 17 for receiving wrapped connections and are retained by inserts 18 of the body 1.
