Title: Improved method of and apparatus for making tart cases and the like
IPC: A21C11/00
Filed: 1931-09-16
Abstract: 385,035. Moulding pies &c. HARBER, L. S., POINTON, J. E., Westwood Works, Peterborough, and BAKER PERKINS, Ltd., Hythe Road, Willesden, London. Sept. 16, 1931, No. 25980. [Class 87 (ii).] Pies, tarts, &c. are moulded and filled by a machine comprising an intermittently rotated table 10 having sleeves 19 supporting pans, the pans being lifted at successive working stations by tubular members 27, 59, 63 mounted on a vertically reciprocating crosshead 22. At the first station the pan is moved into engagement with a dough stream issuing from the nozzle 38 of a depositing machine having rollers 31, Fig. 1, which are intermittently rotated by ratchet mechanism 32, 33, 34 in order to deliver a measured quantity of dough. The dough stream is severed by a wire 39, Fig. 6, maintained in contact with the nozzle by a spring 45, Fig. 1, and reciprocated by cam mechanism 42, 41. The pan, with its measured dough portion, is lowered on to its sleeve 19 and the table is then advanced to the next working station, at which the pan is raised by a spring- pressed cup 48, Fig. 6, into contact with the yielding annular wall 55 of a fixed moulding die 51. The dough is thus shaped in a closed chamber whereby subsequent trimming of the edge is eliminated. The wall 55 may have an electrical heating element 56 to prevent adherence of dough. A valve 57 in the die admits air after the moulding operation to facilitate the discharge of the moulded pie, which is then lowered back, in its pan, on to the sleeve 19. The table is then advanced to stations where the pie receives a filling from a nozzle 60 and a covering from a nozzle 62, these nozzles communicating with chambers to which material is first supplied from hoppers 64, 65, Fig. 3, by an oscillating ported valve 69, the material then being discharged through the nozzles by plungers 79, 80 actuated through bell-crank levers by cams. In the absence of a pie, the filling material falls through the tubes 59, 63 to a receptacle 61. The machine is driven through gearing by an electric motor 16. Both or one of the depositors may be dispensed with, or temporarily disconnected.

Title: Improvements in or relating to the production of p-methyl-amino-phenol
IPC: C07C215/76
Filed: 1945-10-05
Abstract: N-Methyl-p-aminophenol is prepared by the catalytic hydrogenation of N-methylene-p-aminophenol, or equivalent proportions of p-aminophenol and formaldehyde, in the presence of a caustic alkali, e.g. caustic soda or the corresponding methoxide and using a methyl alcohol medium, preferably in such quantity that at the end of the hydrogenation it does not contain more than 20 per cent water.  One mol. of caustic alkali is preferably used per mol. of the phenol employed, and the preferred catalyst is activated nickel, e.g. Raney nickel.  In an example, Raney nickel is added to p-amino-phenol, methyl alcohol and caustic soda, and the resulting mixture treated with hydrogen and formaldehyde to yield N-methyl-p-aminophenol. Unreacted p-aminophenol is recovered as N-benzilidene-p-aminophenol by adding controlled quantities of benzaldehyde.

Filed: 1973-06-04
Abstract: 1386562 Moving-magnet instruments FORD MOTOR CO Ltd 4 June 1973 [21 June 1972] 26502/73 Heading G1Q In a moving-magnet instrument, two coils 20, 22 are wound on a support 36 forming a veeshape and a disc permanent magnet 44 is supported between them, the magnet 44 being fixed to a shaft 46 which also carries a pointer (52), Fig. 2 (not shown). The support 36 is made from two mating halves defining a chamber containing the disc 44 and filled with a silicone fluid. The two coils are identical and are connected across independent terminals 70, 72, and a common terminal 74. In use terminal 74 is supplied with a fixed voltage (which may be stabilized using a Zener diode) and terminals 70, 72 are respectively connected to fixed reference and variable sensing resistors. Change in the variable resistor changes the current through only one winding Fig. 4 (not shown) and thus alters the direction of the resultant magnetic field. The magnetic disc 44 aligns with the resultant field and thus moves the meter pointer (52) over a scale (54), Fig. 2 (not shown) In order to indicate no current flow in the meter, a ring of magnetic material 76 is fixed to the support 36 around the shaft 46. On cessation of current flow, magnet 44 rotates until one of its poles aligns with a gap 78 in the ring.
