Title: Improvements in or relating to oil engines
IPC: F02B23/04
Filed: 1938-06-25
Abstract: 509,086. Oil engines. BUCHI, A. June 25, 1938, No. 18901. [Class 7 (iii)] A pre-combustion chamber 8 discharges into combustion spaces 22, 23 formed by depressions 24, 25 in the piston concentric with the inlet and exhaust valves. The depressions are so deep that the inlet and exhaust valves may be held open simultaneously while the piston is in its uppermost position during the scavenging stroke. Fuel is delivered into the chamber, by a pump driven from the cam-shaft. The fuel and burning mixture may be delivered through openings in the side or base of the chamber either as a fan-shaped jet or as jets 26, 27 which enter the spaces 22, 23 tangentially and set up rotary movements therein. Additional openings 36 deliver jets to the parts of the spaces near the chamber. In engines having two inlet and two exhaust valves in each cylinder, the chamber 8, Fig. 6, is disposed centrally and the openings 17 are arranged so that rotary movements in the same or opposite directions are created in the spaces beneath the valves. Alternatively, the chamber may have only two openings 17 which deliver common jets to each pair of spaces.
Patent GB-793755-A (GB)
Title: A process for the manufacture of aminocarboxylic acids
Filed: 1956-06-19
Abstract: Aminocarboxylic acids are prepared by adsorbing cyanocarboxylic acids on anion exchangers and hydrogenating in the presence of a catalyst such as finely-divided nickel.  The process can be carried out at normal or higher pressures (e.g. 80-100atmospheres) and at room or higher temperatures (e.g. 40-60 DEG  C.).  When a strongly basic ion exchanger is used ammonia may be added to repress the formation of secondary amino compounds.  The product is dissolved by a strong acid, e.g. hydrochloric, and can be obtained as a salt by evaporation of the solution.  The free aminoacid is obtained by passing the solution through an anion exchanger to bind the salt-forming acid or through a cation exchanger with subsequent elution with ammonia. When a mildly basic ion exchanger is used for the reduction step the free aminoacid is obtained directly.  Examples are given of the production of b -alanine (hydrochloride), amino-capric acid and amino-caproic acid from cyano-acetic acid, o -cyanopelargonic acid and o -cyano-valeric acid respectively.

Abstract: 381,214. Optical sound recording and reproducing apparatus. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Gauthier, M. C. ; 10, Nishuane Road, Montclair, New Jersey, U.S.A.) July 1, 1931, No. 19024. Convention date, April 10. [Class 40 (ii).] Optical sound-film recording or reproducing apparatus is provided with two freely rotatable rollers disposed one at each side of the light beam and engaging opposite sides of the film to guide the film transversely of the beam. As shown by Fig. 1, a sound-reproducing apparatus is enclosed in a casing 1 having a compartment 3 which houses a light source 5. Within a compartment 2 is secured, upon an attachment 8, shown enlarged in Fig. 2, one end of a lens tube 9 which extends through a wall 11 and is located adjacent to the light source 5. The film guide of the invention comprises two rollers 12, 13, freely rotatable in bearings carried by the attachment 8. Located between the lens tube 9 and the filmguiding means is an adjustable masking device comprising two masking- elements 24, 25 the former being slidably mounted transversely on rods 26, 27 and adapted to be moved by a knurled nut 31 on the rod 27 against the action of a spring 30, as shown by Fig. 3, which is a sectional view along the line 3-3 of Fig. 2. The masking element 25 is mounted and arranged for sliding movement on two similar rods 28, 29 and these masking elements can thus be given relative movement to permit the forming of a light aperture of any desired length opposite any portion of the soundpicture film F, Fig. 1. The disposition of the guide rollers 12, 13 is such that they are spaced apart in the direction of the length of the film by a distance substantially equal to the width of the reproducing light beam as determined by the optical system and light slit contained in the tube 9, while the displacement relatively to the plane of the film is such that the filmcontacting points of their peripheries are spaced apart a distance substantially equal to the thickness of the film F. The film-driving means includes a constant speed sprocket 33 with which co-operates a film retaining roller 34 mounted rotatably on a pivoted arm 60 so that it may be maintained in engaged or disengaged position by a spring member 62 which bears against a wedge-shaped extension of the arm 60. Before the film passes to the guide rollers 12, 13 it travels around a tension roller 41 which rotates against the friction of a spring-pressed friction disc 42 which is adjustable by a nut 44. The film is made to contact with the roller 41 by a retaining roller 45 which is rotatably mounted on one arm 46 of a bell-crank lever pivoted at 47, a leaf spring 50 forming part of the arm 46 to allow the roller 45 to yield slightly under an abnormal tension in the film. The photo-electric cell 35 is supported adjacent the film by pads 37, 38 mounted on spring-held arms 39, 40 to prevent transmission to the cell of vibrations caused by the film feed mechanism.

IPC: A24C3/00
Filed: 1964-05-08
Abstract: 1,110,443. Cigar making machines. GALLAHER Ltd. 21 July, 1965 [8 May, 1964], No. 19411/64. Heading A2C. A continuous rod machine for the manufacture of cigars comprises means for forming tobacco into a continuous filler stream, means for enveloping the filler stream with a continuous wrapper of tobacco to form a wrapped rod, cutting means for cutting the wrapped rod into lengths, and a split die for reducing the cross-section of the rod at regularly spaced intervals. Tobacco is fed from a hopper 1 by a band 2 to the underside of a suction band 3. Discs 4 are provided for trimming the tobacco filler stream and pockets are provided on the discs for removing an added amount of filler at regularly spaced intervals equal to the length of two finished cigars. The trimmed stream passes to a garniture 8 together with a wrapper of reconstituted tobacco drawn off a reel 5, to knives 6 which slit the wrapper in the region which will form the end of reduced diameter in the finished cigar. The rod and wrapper then pass successively through a main lap paster 9, a heater 10 and cutting station 12 where the rod is cut into double length cigars each of which has the portion of reduced diameter formed by discs 4 in the centre. A paster 13 applies adhesive to the side flaps of the wrapper and the double cigar lengths are then acted upon by a pair of co-acting dies 14 which form the ends of reduced diameter. From the dies 14 the lengths pass to a station 15 comprising upper and lower compression bands and side rollers for imparting a square crosssection to the cigars and hence to a drum 16 on which they are cut into single cigars by a knife 17. The. die sections may be rotated with respect to the cigar rod during pressing and are arranged to travel in the direction of the rod at the same speed.

Title: A continuous-flow evaporator for concentrating brine
IPC: B01D1/04
Filed: 1953-07-15
Abstract: <PICT:0762182/III/1> <PICT:0762182/III/2> A continuous flow evaporator comprises two superposed chambers, the upper chamber 6 (Fig. 1) having a heating-means which effects the evaporation; a heat exchange coil 3 is disposed in the lower chamber 1, an inlet-valve 2 for introducing the weak brine is connected to the base of the lower chamber, a pipe 5 conducts the brine from the lower into the upper chamber, and the upper chamber is surrounded by an open-topped casing into which the hot concentrated brine overflows and from which it passes, via pipe 11, to the heat exchange coil 3 in the lower chamber where it preheats the weak brine.  The brine is boiled in chamber 6 by steam coil 8, the condensate from which passes, via steamtrap 13, into coil 7 where it heats the brine entering chamber 6 through pipe 5.  The vapours leave the evaporator through vent 9; and the concentrated brine is withdrawn through pipe 12.  The evaporator is suitable for concentrating calcium chloride brine which has been used to prevent deposition of ice on refrigerating coils; and Fig. 2 shows a system which automatically brings the evaporator into operation when the gravity of the brine falls below a pre-determined value. Brine is pumped from tank 26 by pump 18 to a spare pipe in air cooler 27; whereby the brine is sprinkled over the refrigerating coils, and is then collected in tank 26.  Brine is also pumped from tank 26 through pipes 15 and 16, and float switch 17; and is returned to tank 26 through pipes 19, 20.  When the gravity of the brine falls below a predetermined value, switch 17 opens valve 22, and some of the brine then flows through pipe 25 to the evaporator, while at the same time the diaphragm controlled steam valve 14 of the evaporator is opened by pressure transmitted along pipe 23.  The concentrated brine leaving the evaporator through pipe 12 is returned to tank 26 via pipe 20. When the required gravity is regained, valve 22 is automatically closed and the evaporator ceases to operate, but the level of the brine therein is maintained by non-return valve 24.
