Filed: 1966-01-11
Abstract: 1,106,735. Friction clutches; clutch control. W. SCHIFFER. 11 Jan., 1966 [12 Jan., 1965; 3 Jan.. 1966], No. 1353/66. Headings F2C and F2L. Engagement of a friction plate clutch 15, 17, which connects an I.C. engine cooling fan 19, or water pump, to a driving shaft 14 is initiated at a predetermined temperature by a permanent magnet 1 and an associated thermoferritic keeper 2 the Curie point of which is at the predetermined temperature, the arrangement being such that below the predetermined temperature the flux path of the magnet 1 is completed through the keeper 2 to overcome a plate spring 3 to disengage the plate clutch 15, 17 (Fig. 2, not shown), whilst above the predetermined temperature the keeper 2 becomes non-conductive to magnetic flux and hence allows the plate spring 3 to engage the clutch. As shown, the keeper 2 is fast with a drum 18 connected with the fan 19 and flanged clutch hub 17 which co-operates with the clutch disc 15 fast on the driving shaft 14, the spring 3 being secured to the drum 18 and to a collar 13 which is rotatably mounted but axially fixed on the shaft 14, and to the end of which is fixed the magnet 1. In Figs. 3 and 4 (not shown), the driving shaft (114) carries the clutch disc (115) at its outer end to co-operate with the fan hub (117) rotatably mounted on an axially movable but rotatably fast collar (113), which collar carries the magnet (101) and is connected by the plate spring (103) to the drum (118) which together with the keeper (102) are fast on an engine block (126). In the Fig. 3 embodiment, the keeper (102) has an adjacent chamber (124) ventilated from a space (126) in the engine block by a flow of liquid or gas through feed and outlet channels (127 and 128), whilst in the Fig. 4 embodiment the keeper (102) is connected to the engine block by a copper heat conducting bridge (125).

Abstract: 915,789. Cutters and dies. THYNE Ltd., WILLIAM. April 13, 1961 [Jan. 14, 1960; Oct. 27, 1960], Nos. 1365/60 and 36969/60. Class 31 (1). [Also in Groups XVI and XXII] A method of making a die-set for creasing and cutting cartons or box blanks comprises forming a male and female die of each die-set from two complementary matrices, producing the male matrix so as to provide a means of forming in the male die ridges, or slots to house ridge inserts, forming grooves in the female matrix which during forming of the female die produce thereon pairs of ridges, a score being formed between the ridges of each pair. A female die 1 comprising a backing sheet 2, e.g. of canvas, metallic foil, sheet metal or plastic, is pressed on to a female matrix 8 having pairs of plasticfilled grooves 9 and marked hole centres 10; upon removal of the die the plastic adheres to the sheet 2 to form ridges 3 divided by a score 4. The holes 11 are drilled or punched in the die 1 at the positions of the transferred marks 10. A male die 5 comprises casting. a resin pad 6 in a male matrix having partitions 13, rods 14, and pins 15 which produce slots for the creasing and cutting rules 7, transverse holes for rods 17 and die alignment holes 16. A number of male dies are set in a chase and located by rods 17 to make a forme and a corresponding number of female dies are registered with the male dies by means of alignment pins through holes 16, 11 prior to being secured to a cutting or make-ready plate. In a modification, the male die may be formed from a pad of thermoplastic material, the leading side of which may be cellular, pressed on to upstanding heated knives of a matrix arranged in the same manner as the partitions 13 to form slots into which are inserted the creasing and cutting rules which may be fixed with an adhesive. In a further modification, the male matrix is formed with grooves which produce ridges on the die and grooves similar to grooves 9 are formed in the female matrix which produces ridges 3 and scores 4 on the female die; in both cases the die may be made from a malleable material such as copper.

Abstract: 461,040. Jet pulverizers. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 20, 1936, No. 1837. Convention date, Jan. 18, 1935. [Class 59] In a jet pulverizer, the cross-sectional area of the mixing nozzle so contracts from the entrance toward the exit that the acceleration of the material operated on by the working medium takes place gradually over the greater part of the length of the mixing nozzle. As shown in Fig. 2, the mixing nozzle 2 is tapered, the discharge end 6 being flared to increase the pressure of the working fluid before the material is projected upon the impact plate 5. Insufficiently comminuted material falls back onto the untreated material 3 and the fine material is carried by the outflowing air into sifters. The length of the nozzle 2 is such that the air cannot reach its maximum velocity before the material acted upon reaches its own maximum velocity so that the relative velocity between the air and material is not large. The edge over which the material falls into the air jet may be enlarged without increasing the jet area by inserting a body 7, Fig. 3, of stream-line form at the inlet end. In order to obtain a long length of expansion nozzle without increasing the overall length, the nozzle is bent as shown in Fig. 4, impact members 9 of stream-line form being inserted in the straight portions whilst curved deflecting plates 8 are inserted at the bends. The nozzle may be in parts arranged concentrically.

[Also in Group XXVI] A combustion gas generator comprises a rotor having a plurality of combustion chambers and a non-rotary means of leading gas to and from the combustion chambers, air under pressure supplied to one chamber being further compressed by means of pressure developed in a second chamber in which combustion is taking place. The gas generator shown comprises a rotary assembly of five combustion chambers 62, 63, 64, 65, 66 mounted on a shaft 71 by means of support plates 69, 70 and having end plates 67, 68. The rotary assembly is supported within a cylindrical shell 43 having end closure plates 44, 45 with which the rotor assembly end-plates 67, 68 engage. The endplate 44 has two ports 47, 48, air under pressure from a compressor 75 being led through duct 49 to the port 47, while the port 48 is covered by a cap 50 having a fuel injection device 51 and an igniter 52. The end-plate 45 has five ports 53, 54, 55, 56, 57, the port 53 being a discharge port for high-pressure combustion gases, port 54 a discharge port for low-pressure combustion gases, 55 a scavenging port, and the ports 56 and 57 being interconnected by a duct 61. In the first position of a combustion chamber, say 65, air under pressure from the duct 49 blows through the chamber which is open to the scavenging duct 60 at its other end. In the second position of the chamber it is open to the interconnector duct 61, so that air or gases under pressure in the preceding chamber which is in full combustion act through the interconnector duct to further compress the air in the chamber 65. In the next position of the chamber 65 it is aligned with the cap 50, fuel is injected through injector 51 and combustion initiated by igniter 52, the resulting gases acting through the interconnector duct 61 to compress the air in the following chamber. In the next position, the chamber 65 is opened to the high-pressure discharge duct 58 and the gases pass to the gas-turbine 74 which drives the compressor 75, while in the final position, the chamber is opened to the low-pressure gas-discharge duct 59 and the gases pass to the gas-turbine 74 or to another point of use.
