Filed: 1950-02-07
Abstract: 698,873. Closuring containers. FILLING MACHINES, Ltd., and WILSON, A. Feb. 7, 1951 [Feb. 7, 1950], No. 3100/50. Class 125(ii) [Also in Group XXX] A device for detecting and rejecting filled cans not fitted with lids from a number of cans conveyed on a belt 8 comprises a member 1 reciprocable in guides 1a by a lever 4 swung about a pivot 5 by a cam 6 whereby spaced abutments 2, 3 on the member 1 are moved periodically across the belt to arrest a can 16. Whilst the can is stationary, a detector finger 10 carried by a bar 12 moved up and down under the control of a cam 13, moves downwardly towards the can. If the can is without a lid, the finger passes down into the can and a member 11 on the bar moves a detent 14 out of engagement with a sliding member 7 provided with an arched portion 7a straddling the cans. When the finger 10 is lifted out of the can again by the bar 12 being raised by the cam 13, the member 7 moves towards the can under the action of a spring 9 so as to push the can off the conveyer belt. The member 1 when subsequently retracted, moves the member 7 to the position in which it is again engaged by the detent 14 with its part 7a again straddling the cans on the belt. If the can is fitted with a lid, the finger 10 is stopped by the lid and the detent 14 remains in engagement with the member 7.

Title: Manufacture of nitriles of unsaturated fatty acids
Filed: 1934-02-01
Abstract: Nitriles of unsaturated fatty acids of high molecular weight are manufactured by passing a saturated or unsaturated hydroxy-fatty acid containing more than ten carbon atoms or an ester thereof, alone or mixed with a solvent or diluent, together with ammonia at a raised temperature, preferably about 300--450 DEG  C., over a catalyst capable of splitting off water, e.g. aluminium oxide, thorium oxide or silica gel.  As solvents or diluents may be employed other fatty acids, also nitriles, hydrocarbons or alcohols.  The products may be used for the preparation of assistants in the textile industry or as intermediate products for obtaining substances having long carbon chains, e.g. higher unsaturated amines.  In examples: (1) commercial ricinoleic acid is passed with ammonia at 350--360 DEG  C. over silica gel, yielding a p  doubly unsaturated nitrile C18H13N (ricinenic nitrile), which may be reduced with sodium and alcohol to the corresponding amine; (2) vitreous alumina is employed as catalyst in (1); (3) the ricinoleic acid of (1) is replaced by castor oil; (4) ricinoleic acid methyl ester is passed with ammonia at 350--370 DEG C. over bauxite, producing ricinenic nitrile; (5) a solution of a -hydroxystearic acid in a fatty acid nitrile is passed with ammonia at 350--450 DEG  C. over silica gel to produce an unsaturated nitrile C17H33CN; (6) an alcoholic solution of a -hydroxystearic acid ethyl ester is similarly treated, giving the same product; (7) a -hydroxylauric acid is treated as in (5) to yield an unsaturated nitrile C11H21CH; (8) a solution of 9 : 10 - dihydroxystearic acid in a fatty acid nitrile is passed with ammonia at 400--450 DEG  C. over silica gel, producing a doubly unsaturated nitrile C17H31CN.

Title: Multiple tooth broaches
Inventor: MOULD RONALD EDWIN
IPC: B23D43/02
Filed: 1965-01-28
Abstract: 1,082,043. Broaching. ROLLS ROYCE Ltd. Jan. 28, 1965, No. 3770/65. Heading B3L. In a multiple tooth broach, each tooth is form relieved and also further relieved so that the leading edge of at least one flank of each successive tooth is set back towards its opposite flank relative to the leading edge of the corresponding flank of the preceding tooth. When the broaching of a fir-tree slot is commenced, the cutting load on the advancing broach teeth pushes the sides of the slot apart. This causes following teeth to be gripped by the work, resulting in damage and work-hardening of the metal. To avoid this, the teeth are relieved along the lines Q-Y 4  and Q-Y 3  as follows. The back end of the broach bar is lowered, and a grinding wheel 11 of the form indicated by broken lines is moved into contact with the broach and is traversed horizontally along the teeth. The bar is then tilted in the opposite direction and a further traverse is made. The portions of the teeth included between the dotted and full lines are therefore prevented from rubbing. Alternatively, the shape thus achieved can be imparted to each tooth individually. The form relief angle (a) is 2¢- 5 degrees. The slot is subsequently completed by a finishing broach. The broach may be tapered on one side only. A roughing broach may be produced from a worn finishing broach by alternately moving a grinding-wheel in the directions A, B, Fig. 6 (not shown), to remove the amount X.

Title: Improvements relating to the automatic temperature regulation of partitioned enclosures, such as the compartments of railway carriages
IPC: B61D27/00
Filed: 1933-02-07
Abstract: 397,024. Heating by circulation of fluids. BARON, H., 231, Strand, London. -(Neufeldt & Kuhnke Ges. ; Werk Ravensberg, Habsburgerring, Kiel, Germany.) Feb. 7, 1933, No. 3774. [Class 64 (ii).] The flow of heating fluid in the radiators 5 of a partitioned enclosure such as a railway carriage is controlled by a valve 2, Fig. 1, in accordance with the maximum instantaneous temperature in the enclosures. This may be effected by each compartment containing the heat sensitive element 7 of a thermostat with an expanding bellows 9. A plate 12 is moved to operate the valve 2 whenever any one of the bellows 9 moves beyond a certain distance under the influence of rising temperature in its particular enclosure. In a modification a vapour pressure thermostat is used, the heat sensitive portion, containing liquid 24, Fig. 3, and vapour 25, extending through all the compartments and thus producing the desired effect as the vapour pressure will always be that corresponding to the temperature of the hottest portion of the heat sensitive element. The thermostat acts indirectly on the valve 32 through bellows 26, 29 and connection 28, which are filled with heat expansible fluid, a branch 33 being provided extending to a chamber 34 outside the enclosures to furnish a superimposed control according to outside temperatures. The heat sensitive element may be composed of separate sections of piping for each chamber jointed as shown in Fig. 5, with a washer of heat insulating material 42 between, or a number of tubes arranged in parallel, or two tubes forming an annular channel for the liquid and vapour. The element may also be constructed to slope upwards or downwards to the centre of each compartment.

Title: Improvements in or relating to registers for automatic electronic exchanges
IPC: H04Q3/42
Filed: 1954-02-09
Abstract: 777,115. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and PEDDLE, E. A. R. Jan. 25, 1955 [Feb. 9, 1954], No. 3796/54. Class 40 (4). A recurring pulse train is produced in a particular time position out of a possible 10,000 such time positions in accordance with a number received in the form of four trains of impulses, the number of impulses in each train being representative of the digit of a particular denomination. As shown, dial impulses are fed to terminal IT and then to a re-entrant decimal counter CC. If the number of impulses is two, for example, the counter is stepped to point CC2 whose output thereupon opens gates G2, G12 ... G32 to pass pulse trains M2, C2 ... U2 from a master generator to gates G41 ... G44 respectively. At the end of the first impulse train a device DC emits a pulse to step the counter R to position RM thereby opening gate G41 to pass the train M2 to a pulse generator PGM which is arranged to produce a recurring pulse having a position determined by that of the input pulse, in this case M2. The next impulse train steps the counter CC from CC2 onwards. Thus if the next train consists of seven pulses CC9 will be operated to open a corresponding vertical column of gates G9 ... G39. At the end of the train the circuit DC steps the counter R to position RC. Thus a pulse train C9 is passed via gates G19 and G42 to generator PGC which thereupon generates a pulse train whose timing is determined by pulse C9. Subsequent digits cause generators PGD, PGU to be set in the same manner. Each M pulse occupies a time equal to a whole cycle of 10 C pulses each of which occupies time equal to a whole cycle of 10 D pulses and so on. A pulse train derived from gate G45 due to coincidence of pulse trains from all four generators PGM ... U therefore occupies a unique position individual to the number represented by the four sets of impulses. This pulse train is passed to the gate G46 which is opened when the counter R is in its fourth position to pass the train to an output terminal OT. The system may be restored by applying a pulse to terminals RIT to zeroize the counters. If the pulse position is required to bear a direct relationship with the number registered then it .may be arranged to use the output from circuit DC to restore the counter CC after each digit. Valve circuits for the counter gates and the end of pulse train detector are described. The generators PGM ... U may be as described in Specification 767,683 or 767,685. The invention may be used to mark a called line.
