Title: Improvements in apparatus for applying edible fats to bakery dough
IPC: A21B5/00
Filed: 1955-03-07
Abstract: <PICT:0784948/III/1> Dough pieces on a conveyer are sprayed before baking with liquid fat intermittently delivered by spraying nozzles connected respectively to the cylinders of a multi-cylinder pump and the operation of the latter is so timed, in relation to the speed of the conveyer, that each dough piece is subjected to several collective discharges while passing the spraying nozzles. Conveyer belt 11 is carried on rollers 12 journalled in brackets 13 and its top run extends flush with the top of casing 10 and is supported on flat strips 17 or small rollers.  One roller 12 is driven through gearing including reduction gear-box 14 by an electric motor 16.  The output shaft of gear-box 14 is connected by a chain (or belt) 21 to the shaft of a high-pressure pump 22. Edible fat is contained in a tank 23 heated by a thermostatically-controlled electric heater 24 and flows through a pipe 25 to the intake of pump 22 which has three plungers working in three cylinders each connected by a pipe 26 to a nozzle 27. Each pump cylinder communicates with a common suction chamber through inlet ports which are shut off during the latter part of the delivery stroke, the trapped oil having access to a circumferential helical groove so that, at a point determined by the angular position of the plunger, it uncovers one of the inlet ports and terminates delivery by allowing oil to return to the suction chamber.  The output is controlled by rotating the plungers by a rack-rod 28.  Means 30 are provided on each nozzle 27 for altering the type of discharge produced.  The dough pieces are placed on the conveyer 11 at its right-hand end and travel through a sheet-metal tunnel to a hood 32 containing the nozzles 27 and thence to a second tunnel 33.

Title: Improvements relating to fumigants
IPC: A01N25/00
Filed: 1944-04-11
Abstract: An absorbent material for volatile liquid fumigants is prepared by treating comminuted wood by extracting oils and resins therefrom by means of a suitable solvent, e.g. benzine, and then boiling the wood in slightly acidified water.  A soft wood such as balsa wood is preferred.  The acidification of the water may be effected with sulphuric, oxalic or acetic acid, and the acidified water removed, after the treatment, by means of a centrifuge, and the wood dried. By this means a product is obtained which is light and bulky and has a slightly acid reaction due to the presence therein of a residue of about 0.5 per cent of acid. Specification 407,792, [Group VI], is referred to.ALSO:Hydrocyanic acid or other volatile liquid fumigant is absorbed in a light, bulky, slightly acid product obtained by treating comminuted wood by extracting oils and resins therefrom by means of a suitable solvent, e.g., benzine, and then boiling the wood in slightly acidified water.

Title: High voltage switch having auxiliary latch operating means for the current interrupter
IPC: H01H33/12
Filed: 1969-02-07
Abstract: 1,208,853. Automatic circuit-breakers; loadbreak disconnecting switches. S. & C. ELECTRIC CO. 7 Feb., 1969 [3 April, 1968], No. 6706/69. Heading H1N. In a load-break disconnecting switch as described in Specification 972,037, in which an overcurrent solenoid-operated auxiliary trip 59, Fig. 1, is provided to trip a latch member 24, Fig. 2 (in housing 16), to release spring-loaded contacts (not shown) in a circuit interrupter 17 a collapsible linkage 92, 96 is provided (as in housing 35) whereby the latch member 24 may return to its latched position independently of the return of the solenoid trip 59. The contacts (not shown) of the circuit interrupter 17 are arranged in series with the main switch blade contact 18 which is opened subsequently by an operating link 14 acting through a rotatable insulator 12, coupled shaft 15 and linkage 19- 22. Rotation of shaft 15 also effects release of the latch mechanism 24 if not previously released by the auxiliary trip 59. The armature 84, Fig. 8, of solenoid 85 of the auxiliary trip 59 rotates a shaft 57 coupled through rotatable troque-transmitting shafts 37, 55 and insulator 38 to a shaft 34 in housing 35. Movement of the shaft 34 is transmitted to a shaft 29 carrying lever 27 engaging the latch release member 24, through levers 33, 31 interconnected by the collapsible links 92, 96. Spring 98 normally holds link 92 against a stop 94 on lever 31 whereby the links are held just over-centre for the transmission of thrust. After operation to the latched position (shown hatched) stop 94 moves links 92, 96 to the right of over-centre whereby a return spring 101 restores levers 31, 27 to their initial (full line) position by collapsing the links 92, 96. Stop 25 on lever 27 which initially engaged the latch release member 24, is thereby withdrawn from the member 24 to permit the latch to be reset irrespective of the return of the armature 84 and lever 33 to their initial positions. The coupling between the armature 84, Fig. 8, and shaft 57 includes a pivoted latch 74 which prevents inadvertent rotation of the shaft 57 unless the solenoid 85 is energized. The armature 84 is coupled to the shaft 57 through a freely-rotating lever 87 having a lost-motion connection 88, 89 with a lever 71 keyed at 70 to the shaft 57. The pivoted latch 74 normally engages a notch 72 on the lever 71 to prevent its movement and is released only by the initial movement of pin 81 on the armature 84 when the lost motion is taken up at the connection 88, 89.

Title: Method and device for extruding tubes of thermoplastic materials
IPC: B29C48/09
Filed: 1957-03-01
Abstract: 810,703. Extruding tubes. S.A.S. LAVORAZIONE MATERIE PLASTICHE (L.M.P.) DI M.I. COLOMBO & C. March 1, 1957 [March 22, 1956], No. 6886/57. Class 87(2). Tubes of thermoplastic material are extruded by causing the material heated to its softening point to travel through a tubular shaping passage 17, cooling the outer surface of the tube within a terminal section 17a of the passage to cause at least partial setting while maintaining the inner surface in a softened condition, and guiding the inner surface over a polished support 15a while further cooling the tube from the outside to remove heat from the inner surface and to solidify it. In the figure a core 15 is supported by a spider 14 in a bore through casings 12, 13 to confine a tubular passage 17 having an inlet 18 and an outlet section 17a. A restriction 17d may be provided on the portion 17c of passage 17 to oppose the flow of material and thus avoid the formation of voids by the blades of the spider 14. Electric heating means 27, 32 are provided to heat the outer and inner walls of an intermediate section 17b of the tubular passage 17 and a cooling jacket 22 surrounds the outlet section 17a. A core extension 15a has a polished outer surface to support and guide an extruded tube T issuing from the tubular passage 17. The external layers of this tube are set by coming into contact with the cooled surface 20, which is highly polished, while the internal layers remain fluid until cooled, while supported on extension 15a, by water sprayed from nozzles 40. The lower nozzles may be replaced by a trough of water in which the extruded tube is partly immersed. The radial thickness of section 17a is inwardly enlarged, thus admitting of a slight shrinking of the tube T upon cooling of its external surface by the surface 20 and also' affording a supplementary clearance to which a certain quantity of still fluid material can flow.
