Patent GB-133449-A (GB)
IPC: B64C11/36
Abstract: 133,449. Turnbull, W. R., and England, E. C. G. Oct. 10, 1918. Screw propellers.-Relates to aerial propellers for aircraft or marine vessels, and consists in the provision of means for varying the pitch during rotation. The blades B are each mounted to swivel on a radial axis B', Fig. 1, extending from a radial arm A' fixed to the boss A. Bearing- plates D, E, are provided on the blade and radial arm respectively.. The plate E has two radial arms E<2>, E<3>, Fig. 2, carrying bearings for a spindle G provided with a worm G'. The worm engages with a toothed sector H carried by the plate D. The spindle carries at one end a spocket-wheel J connected by a chain J<1> to the spocket-wheel of the other blade, and at the other end a friction disk K. The pitch of the blades is therefore varied when the disk K is rotated. The mechanism for rotating the disk K is shown in Figs. 3 and 5. A base-plate L mounted on the machine carries upstanding pins L' extending through slots M' in a sliding yoke M. Two brake shoes N, N<1> are pivoted on pins N<2>, N<3> and carry friction pads 0, O<1>. The brakes are arranged so that the orbit K‹ of the disk K passes between them. The yoke M is moved to one side or the other by a link V, quadrant U, rod R, and handle R', Fig. 5, so that one or other of the brakes N, N' is brought into contact with the disk K in each revolution, and the disk K is thus given an intermittent rotation. When the disk K has been rotated sufficiently, the handle R is allowed to return to its mean position under the action of the springs T. In a modification, Fig. 6, the disk K is replaced by a serrated soft-iron disk which passes in its revolution close to two electromagnets W. One or other of these magnets is energized by operating a control switch so that one of the projections K<2> is retarded on passing the magnet at each revolution, and the disk is rotated intermittently in a direction depending on the magnet which is energized. In both modifications, the revolving propeller is normally unconnected with the operating-parts of the pitchvarying gear.

Title: Packing machine
IPC: B65G57/00
Filed: 1970-03-19
Abstract: 1307900 Packaging H GRASVOLL G G MAGNUSSON and K I WEINER 19 March 1970 [27 March 1969] 13373/70 Heading B8C In a machine for packing milk cartons 6 from a conveyer 5 into a container 27, rows of cartons are transferred by a pusher 9 on to a plate 8 which is subsequently advanced into the container and which has associated guide members 16 and 44 to prevent the cartons fanning out as they are pushed on to the plate. The guide member 44 is fixed to the plate to ensure that the cartons move with the plate when it is advanced, and the guide member 16 moves out of the path of the plate when it is advanced. The plate is moved by a piston and cylinder 13, 14 acting through a chain 49 which is secured to the plate and is engaged by a set of pulleys 46, 47, 48 on the piston. When the piston is extended, the plate is withdrawn from the container, and a projection 52 on the pulley assembly engages the guide member 16 to hold it in its operative position. When the piston is withdrawn to advance the plate, the guide member pivots under gravity about an axis 15 to clear the path of the plate. Cartons are stripped from the withdrawing plate 8 by the lowering of a stripper plate 18, and after a layer of cartons has been received by the container, a container supporting carriage 24 is lowered into engagement with one of a set of stops 36 to receive the next layer. Rows of cartons are transferred to the plate 8 from a conveyer section 2. When the section 2 is full, the leading carton contacts a micro-switch to cause the section to be raised by a piston and cylinder 4 to the level of the plate 8 and to cause a pressure plate 38 to arrest the cartons on the main conveyer run 5.

Title: Improvements in or relating to fuel burners
IPC: F23C7/00
Filed: 1953-05-13
Abstract: 739,732. Burners. SCHIELDROP, B. H. May 13, 1954 [May 13, 1953], No. 13435/53. Class 75 (1). In a burner comprising a central jet 3 for fuel or air and a series of surrounding jets 2 for air or fuel, one side wall 5 of each surrounding jet is inclined to the axis of the central jet to a greater extent than the opposite side wall 4 and control'members 7 having walls 11 parallel to the side walls 4, 5 of the surrounding jets are movable into and out of the surrounding jets and are adjustable to bring adjacent walls of a jet and a control member towards and away from each other. The side wall 4 of each surrounding jet is preferably parallel to the axis of the burner and the opposite wall 5 is inclined to the burner axis inwardly towards the front of the burner. The other two walls 6 of the surrounding jets are circumferential and are engaged by circumferential walls 10 of the control members. The control members are mounted at equal radial distances on an annular support 8 mounted on a tube 9 surrounding the central jet 3. The annular support 8 is moved axially by a lever 12 connected by a link 13 to a collar 14 rotatably mounted around the support 8. A projection 16 on the support 8 is held by a spring 18 in contact with a pivoted rest 17, the inclination of which is adjustable by means of a member 19 to vary the angular position of the control members. An air flow passage is formed between each control member and a side wall of each surrounding jet and due to the different inclinations of the side walls of the surrounding jets to the burner axis the two air flows from each jet are differently inclined and consequently by varying the relative sizes of these air passages the amount of air swirl can be varied to alter the length of the flame.

Title: Improvements in apparatus for heat-treating metals and alloys
IPC: C21D9/00
Filed: 1923-05-26
Abstract: 207,149. Western Electric Co., Ltd., (Assignees of Kochendorfer, F. S.). Nov. 15, 1922, [Convention date]. Annealing.-In an apparatus for heat-treating metals, the metal in strand form or in the form of a loaded conductor is fed into the heating chamber by a chain mechanism driven at a fixed speed and led away therefrom by a variable speed chain mechanism driven at such a speed that substantially no tension is exerted on the material which is under heat treatment, and a substantial degree of tension on the material between the variable speed mechanism and the take-up spool. The metallic strand is pushed by a feeding device 24 through a tube 21 extending through two furnaces 16, 17 preferably heated electrically and through a tube 22 surrounded by a cooling tube and then through a quenching apparatus 43, being then acted upon by a similar feeding device 25, the devices 24, 25 being described in detail in Specification 207,151. The tubes 21, 22 are connected by a coupling 27, Fig. 8, comprising sections 28, 29, screwed together, the part 27 having an opening 50 to which is connected a pipe 49 through which a non-oxidizing and non-reducing gas is passed. Mounted on the pipe 22 is a plug 32 on to which is screwed aT-pipe fitting 34 into the other end of which is screwed one end of a pipe 35 in which the cooling liquid circulates, the water &c. entering through a pipe 38 and leaving by a pipe 39, a coil spring 40 being provided to form a tortuous passage for the cooling liquid. The strand after leaving the cooling chamber passes through a quenching apparatus 43, in which the strand passes over trough-shaped members 44 provided at one end with a roller 45, the quenching medium being sprayed into troughs 47 in the members 44 bv nozzles 46. The overflow passes into the casing 41 and is drained off by a port 48.

Filed: 1976-04-07
Abstract: 1503416 Transistor monostable circuits AMF Inc 7 April 1976 [25 July 1975] 14078/76 Heading H3T [Also in Division H2] In a static inverter (see Division H2) a monostable circuit 18 is arranged to produce shortduration pulses initially and longer-duration pulses after a predetermined starting time interval. As described, when starting, capacitor Cs is arranged to charge relatively slowly from voltage regulator 13 so that transistor Q5 produces no bias to the emitter of Q3 so that this transistor becomes turned on after C2 has charged via resistors R4, R5 to 0À8 v. A short-duration pulse is thus available from Q4. C2 is now discharged by a pulse from 15 which turns off Ql and turns on Q2. When Cs charges sufficiently to break down Zener diode CR1, Q5 provides a bias of approximately 8 v. to the emitter of Q3 so that C2 has to charge to a higher voltage in order to turn on Q3 and thus longer duration pulses are obtained from Q4. In Fig. 3 (not shown) the base circuit of Q5 is replaced by a CR time constant.
