Abstract: 429,790. Making boxes. LLOYD, A. E., and COX, F. C., Lloyd's Wharf, Mill Street, Dockhead, London. Feb. 6, 1934, No. 3911. [Classes 83 (ii) and 83 (iv)] [See also Group II] A metal box body is fitted with a hinge pin (round which the lid edge is subsequently folded) by apparatus which receives the box from a shoot or endless belt 58, Fig. 3, carries it round to a press die 60 which punctures and presses two grooves in the side to receive the hinge pin ends, carries it round to a pin inserting station 30 &c. and then it leaves at a discharge shoot station 66. A box fed on to the indexed turntable 2 is received in an aperture 3 therein and held by spring-pressed balls 4. On moving above the former 1, it is forced down over the former by a pusher 16 actuated by cam 9, tappet 8 and lever 5. A die 60 actuated by cam 63 and lever 61 punctures and depresses spaced grooves in the box side. The box is then ejected back into the indexed table 2 and carried round to the drum 30, the groove 31 of which receives a pin 37, Fig. 6, from a hopper 17, Fig. 5, and presents it to the inclined box as in Fig. 6. A cam actuated pusher on the part 39 pushes one end of the pin into the pocket 38, the emerging end of the pin momentarily depressing a spring-pressed slide 41 which on slightly angular pivoting of the box to a more parallel position frees one end from the pusher 39 and partly pushes the pin back so entering its other end into the other pocket 38, thus completing the operation. The hopper 17 is provided with cam oscillated strips 19 and spring strips 27 to keep the hinge pins therein parallel to the feeding slot 18. The drum 30 has spring-pressed pin holders 32.

Abstract: 1493926 Pentacyclic triterpenes from Terminalia sericea INVERNI DELLA BEFFA SpA 10 Jan 1975 [29 Jan 1974] 04042/74 Heading C2U Novel terpenic compounds have the formulae wherein OR 1 , OR 2 , OR 3  and OR 4  are free or acylated hydroxy groups and COOR 5  is a free, salified or esterified carboxyl group. Also novel is the 18α-epimer of the compound of Formula (II) wherein R 1 , R 2 , R 3  and R 4  are each acetyl and R 5  is methyl. The free tetrol acid and its D-glucosyl ester are isolated from Terminalia sericea plants by extraction with an organic solvent. They may be separated by a fractionation step making use of the fact that the free acid (named sericic acid) is preferentially soluble in chlorinated hydrocarbon solvents while the glucosyl ester (named sericoside) is preferentially soluble in aqueous solutions. Sericic acid and sericoside may be interconverted and converted to other compounds of the above formulae by known methods of esterification, hydrolysis, oxidation and salt formation. The 18α-epimer of methyl tetraacetyl sericate is prepared by treating methyl triacetyl sericate with 40% hydrobromic acid in acetic acid. The novel compounds possess cicatrizing and anti-inflammatory properties, and they may be made up into pharmaceutical compositions with suitable carriers.

Apparatus for producing a signal when a train has travelled a distance equal to its own length, e.g. for indicating to a driver when the tail end of a train has left a speed restricted zone, comprises a switch 1 operated by the driver as the head of the train leaves the zone which brings into operation a counter 3, fed by pulses E each corresponding to a set distance travelled by the train and manually set by switch 4 to a count corresponding to the length of the train. Operation of switch 1 triggers a mono-stable circuit 2 which provides an output to reset the counter and to trigger bi-stable circuit 6 to a condition in which an output appears on line a6. This output supplies one input to AND circuit 5 and lights lamp 9 to indicate the apparatus is operating. When a count corresponding to the length of the train is reached a pulse from the counter passes via switch 4 and the AND circuit and returns the bi-stable circuit to its initial state. The change in voltage on line a6 triggers mono-stable circuit 7 which provides an output to operate indicating means 8. In a second arrangement, Fig. 5 not shown) the apparatus is combined with an arrangement incorporating a dead-man's handle for bringing the train to a stop after a predetermined distance of travel.

In one process the derivative has the formula C n F 2n+1 -(CH 2 ) a -X where a and n each=2-20, and X represents a chemical group which is capable of causing the derivative to adhere to the tube wall. In a modification of said one process at least one but not all of the C atoms in the -(CH 2 ) a  chain is substituted with chlorine. The derivative may be incorporated in a continuous or batchwise manner by injecting the derivative into the vapour, by passing the vapour over a solution or emulsion of the derivative or by adding the derivative to the liquid which is to be evaporated to form the vapour. In the shown embodiment liquid is evaporated in electrically heated container 1 and the vapour together with a fluorinated derivative introduced through inlet 11 is passed into condenser 2 where the vapour condenses in drops on tube 6 which forms part of a cold water loop 3. The condensed vapour is discharged through funnel 8.
