Title: Process for the production of organic substances
IPC: C07C2/00
Filed: 1931-02-25
Abstract: <PICT:0378979/III/1> In the reaction of unsaturated aliphatic compounds with hydrogen or halogens, or compounds containing hydrogen, carbon, nitrogen, oxygen or halogens, in apparatus having cooler walls opposite to the hot walls, as described in the parent Specification, bodies of good heat conductivity are disposed between the walls at different temperatures.  When catalysts are used, it is advantageous to deposit them on the heat - conducting bodies, but the latter may themselves be catalysts, e.g. nickel or iron.  A suitable apparatus, as shown in the drawing, has a tube 3 of a refractory material, such as "Pythagoras" composition, mounted in a block 1 of a poor heat-conducting material, and heated by any suitable means such as a resistance wire.  A central tube 2 of a good heat-conducting substance is cooled by means of a suitable medium, such as water, and to this tube the materials of good heat conductivity are applied. The reagents enter by the pipe 6, and the products are collected in the vessels 4 and 5.  Specification 374,055, [Group IV], is referred to.ALSO:<PICT:0378979/IV/1> In the reaction of unsaturated aliphatic compounds with hydrogen or halogens, or compounds containing hydrogen, carbon, nitrogen, oxygen or halogens, in apparatus having cooler walls opposite to the hot walls, as described in the parent Specification, bodies of good heat conductivity are disposed between the walls at different temperatures.

A holder for needles or like articles comprises a mounting member formed as a block-like body of thermoplastic synthetic resin or plastics material attached to a base member and formed with one or more hollow formations of crosssectional dimensions adapted to receive therein a stem or shank-like portion of such an article to embrace it about more than half its circumference so as to retain it in assembled relation with the base member by virtue of elastic deformation of, or frictional engagement with, the mounting member. The hollow formations may be open mouthed slots of undercut form into which the stems may be inserted either laterally or longitudinally or open ended bores extending through the mounting member, the articles being inserted longutidinally. The cross-sectional dimensions of the hollow formations may vary along their length, e.g. decrease along the length, or have local protuberances therein.

Filed: 1917-05-04
Abstract: 127,632. Napier & Son, D., and Rowledge, A. J. May 4, 1917. Starting is effected by supplying to the cylinders, after the inlet and outlet valves have been .secured in their open positions, an initial charge of combustible mixture formed by delivering air to a carburettor from a hand - actuated pump. In the construction shown, a double-acting airpump D delivers through a cock G<1> into a by-pass J leading direct to the induction pump, and also into a pipe H which discharges into a surface carburettor A<2>, the outlet from which opens into the pipe J. Fuel is fed to the carburettor by a neat-feed device B, the float chamber being in communication through a pipe B<3> with the upper portion of the carburettor. Screens A<3> are located in the body of the carburettor above the level of the fuel supply, and a further screen is located at A<5>. Before supplying a combustible charge, the valve G<1> may he closed to the pipe H and the cylinder scavenged by an air charge delivered through the pipe J. Subsequently, the valve is turned to permit the whole or a portion of the air to enter the carburettor. If preferred, the starting charges may be prepared in the carburettor used for normal running, or a separate carburettor may be used as shown. According to the Provisional Specification, a rotary pump may be used.

Filed: 1951-03-19
Abstract: 698,356. Aircraft landing lamps. HARLEY. M. C. March 18. 1592 [March 19. 1951]. No. 6490/51. Class 75(iii) In an aircraft landing lamp having a retractable lamp 1 pivoted on a fixed lamp housing 6 and having an arm 3 connected to one end of a telescopic actuator 4, the other end of which is connectedto the housing 6, one of said connections embodies a connection 7, 8 arranged to collapse under a predetermined wind pressure exerted on the lamp 1 when in an extended position and the connection 7, 8 is arranged to operate a mechanical latching means 10 for the lamp 1 when it assumes its fully retracted position. As shown, the actuator 4 is disposed to one side of the housing 6 and is connected by a universal coupling 9 to the yieldable connection which comprises a friction-loaded lever arm 7 pivoted at 8 and retained in its normal position by a roller 17 on one end of a spring-loaded lever 18 and engaging a detent in the lever 7, as described in Specification 698,339. The lever 7 has an extension arranged to bear on the head 15 of a latch pin 10 normally urged by springs 13 on guide rods 12 to inoperative position. In operation, the actuator 4 is extended to retract fully the lamp 1, after which a slight further extension of the actuator causes the lever 7 to pivot to depress the. latch 10 into locking position. This movement of the lever 7 is controlled by friction plates 23 carried on the pivot 8, but movement of the lever 7 in the opposite direction on forced retraction of the lamp 1 is opposed by additional friction plates, 25, 27 which are connected by pins 26 and 19 respectively engaged in holes 25<1>, 29 in the lever 7 and the fixed housing 6. The, holes 25<1>, 29 provide sufficient clearance for the pins 26, 19 not to restrict the latch operating movement of the lever 7: A microswitch may be operated automatically on forced retraction of the lamp 1 to cause operation of the actuator to return the lever 7 to its normal position. Specification 627,946 also .is referred to.
