Title: Liquid-fuel distributing means for internal combustion engines
Inventor: FISHMAN BERNARD
IPC: F02M69/12
Filed: 1962-06-27
Abstract: 972,446. Regulating I.C. engines. SIMMONDS PRECISION PRODUCTS Inc., and S.U. CARBURETTER CO. Ltd. Sept. 6, 1963 [June 27, 1962], No. 24602/62. Heading FIB. An I.C. engine fuel injection system in which fixed-orifice fuel injection nozzles, situated in inlet ports or induction passages, are supplied from at least one common chamber has an elastically contractible pressurized fuel reservoir 6, Fig. 1, with two outlet ports 13, 14 communicating with the opposite ends of the bore 17 of a shuttle-plunger pump under the control of valve means 22 which opens each port in turn whilst the other remains closed so that the shuttle plunger 18 is impelled by the pressurized fuel to deliver a metered fuel charge to the common chamber 38 at approximately constant pressure. Pressurized fuel from pump 8 is delivered through pipe 7 to chamber 6 which is sealed off by a resilient diaphragm 9, e.g. of neoprene, loaded by spring 10, pressure in chamber 6 being regulated by a valve 19 which spills off excess fuel back to a supply tank. Valve plate 22, which is driven from the engine by shaft 23 and eccentric 24, is nipped between face 12 and face 25 of a block 26, which is assembled with the middle part of diaphragm 9 and a spring-loaded block 29. In operation, pressurized fuel from chamber 6 passes through port 13, when uncovered by valve plate 22, and through passage 15 into chamber 17 to move a stainless steel shuttle plunger 18 to the left (in Fig. I) so that metered fuel in chamber 17 is forced through passage 16, port 14, annular groove 32, passage 34, annular groove 33, passages 35, 36 and 37 into the common chamber 38 and through passages 39 to individual fuel injectors 40. With a further half revolution of shaft 23, the flow in passages 14 and 15 is reversed and the shuttle plunger moves to the right to deliver a further metered fuel charge. The stroke of the shuttle plunger 18 is adjusted by cam 42. In another embodiment an epicyclicallydriven valve plate 22A, Fig. 2, having external gear teeth 49 which mesh with internal teeth 50 on the housing 2A, has pairs of ports 52, 53 interconnected by ducts 54 which are brought into sequential communication with port 14 and passage 35 and with port 13 and passage 55. The passages 35, 55 supply, through ducts 36, 56 and 45, 46, separate common chambers 47, 48 each supplying a group of injection nozzles 40. Specification 708,592 is referred to.

Title: Improvements in the production of crotonaldehyde
IPC: C07C45/66
Filed: 1950-10-11
Abstract: <PICT:0686045/IV (b)/1> Crotonaldehyde is prepared by leading aldol into a hot aqueous electrolyte solution under conditions of incomplete crotonization and distilling off at least part of the crotonaldehyde formed, separating the non-aqueous layer in the electrolyte solution and leading it into a separate hot electrolyte solution under crotonizing conditions while distilling off the crotonaldehyde therefrom.  Thus, as shown, aldol is fed via pipe 2 into a tower 1 about two-thirds filled with an aqueous electrolyte solution maintained at crotonization temperature by means of circulation heater 3.  Acetaldehyde, water and at least part of the crotonaldehyde formed distil off via pipe 4 and are fractionated to obtain pure crotonaldehyde.  Meanwhile, part of the contents of tower 1 flow into a separator 6 where layer formation occurs; the lower layer of spent crotonization liquor is removed at 10 while the upper layer of aldol flows into the second crotonization chamber 8 charged with hot crotonization solution and from which crotonaldehyde distils off.  Spent crotonization liquor is removed via pipe 11.  The process is preferably continuous.  Suitable crotonization solutions contain non-volatile mineral acids or their acid salts, e.g. sulphuric acid, phosphoric acid, sodium bisulphate or mono-sodium phosphate; mixtures of such salts with free acids which have a buffering action and mixtures of alkali phosphates with phosphoric acid may be used.  The solution preferably has a pH of about 2 to 6.  Suitable operating temperatures are between 60 DEG  and 110 DEG  C.  Reduced, atmo spheric or superatmospheric pressures may be used.  An example is given.

Title: Improvements in or relating to means for continuously feeding webs of material
Inventor: DOWNIE CHARLES
IPC: B65H19/18
Filed: 1953-09-09
Abstract: 759,503. Feeding webs. ELDORADO ICE CREAM CO., Ltd. Sept. 8, 1954 [Sept. 9,1953], No. 24993/53. Class 100 (1). Means for continuously feeding web material comprises a pair of feed rollers between which a web is gripped and passed, said rollers having stationary guides extending on both sides thereof and tangentially thereto, said guides lying in circumferential recesses in the rollers, and on either side of the feed rollers a mandrel for a web roll and a set of guide rollers for the web, the arrangement being such that when one web is nearly exhausted the other is introduced between the feed rollers to be fed with the tail end of the first web, so that at least one web is at all times fed between the rollers, e.g. to an ice-cream-block-wrapping machine. Feed rollers 12, 13 are provided with guides 14, 15 secured to brackets 14a, 15a, and the guide 14 is biased against the guide 15 by a weight 5 and a bracket 3 pivoted at 4. Each guide comprises one or more fingers. A web 11 from a roll 18 is passed round guide rollers 19, a spring-mounted guide roller 20, between normally separated prefeed rollers 23, 24, between guide rods 7, 8, and thence between the guides 14, 15 and the rollers 12,13 to the wrapping-machine. A second web 28 from a roll 27 passes round similar rollers 19, 20 and its end lies short of the rollers 12, 13, so that it is not fed. When the web 11 is nearly exhausted, the cessation of tension allows a feeler roller 35 to drop and close contacts 36, 37 to energize a solenoid 53, which causes the roller 23 to move into contact with the roller 24. The web 28 is then fed together with the tail end of the web 11 between the rollers 12, 13, which continue to feed the second web after the first is exhausted. The roll 18 is then changed and the solenoid de-energized. When the web 28 is exhausted, the same process is repeated, a similar roller 35 and contacts 36, 37 associated with the roll 27 energizing the same solenoid. Instead of the rollers 35, photo-electric cells may be used, which detect either exhaustion of or a break in the web, to energize the solenoid. The apparatus may be arranged for manual operation, when the rollers 23, 24, 35 are omitted and the end of the new web is inserted manually between the rollers 12, 13 before the old web is exhausted. According to the Provisional Specification, two pairs of pre-feed rollers, one pair for each web, are provided, the rollers of each pair in permanent contact with each other and driven through dog clutches controlled by solenoids. A feeler arm rests on the circum. ference of each web roll, and when one roll is reduced to a predetermined diameter, the solenoid of the opposite pre-feed rollers is energized to feed in the end of the other web.
