Abstract: <PICT:0801240/III/1> <PICT:0801240/III/2> <PICT:0801240/III/3> An oxygen generating candle, in which the initial rate of evolution of oxygen is a maximum and which is then reduced, for use especially in respiratory appliances, consists of a body of oxygen-producing material with a starting core of ignition material in the centre.  A baffle strip, which stands on edge and extends from top to bottom of the body and across one side of the core to form a narrow path of burning between the baffle and the nearest side of the body is embodded in the body.  In this way the burning surface is at first a maximum and is then reduced.  Fig. 1 is a plan of such a candle, and Fig. 2 is a vertical section. Fig. 3 shows the candle partly burned. The candle is made by inserting the igniting core 8 and the baffle 12 in the centre of a cup 1 having walls higher than the baffle.  The cup is now filled with the oxygen-producing compound 10, and this is pressed home by a plunger, which moves downward until stopped by the baffle.  A flanged sleeve 3 and nut 4 fasten the candle to the base of the respirator canister 2.  A primer 6 is mounted in the outer end of the sleeve, and a priming charge of flash powder 7 is pressed into the inner end.  The candle is ignited by striking the primer by means of some suitable firing mechanism.  The oxygen generated is filtered free from the smoke by means of a dimple plate 14, a screen 15, layers of filtering material 16, and a screen 17, which are held in the candle by means of ring 18 and indentations 19.

Title: Stretch press
IPC: B21D11/02
Filed: 1957-06-24
Abstract: 811,261. Stretch-bending. LALLI, R. A. June 24, 1957 [Sept. 13, 1956], No. 19827/57. Class 83 (4). A stretch press comprises a frame, a heating- box having a heating means disposed therein supported on said frame, a readily removable and replaceable die mounted on said heating- box the die having a contoured surface over which a sheet is adapted to be stretched, clamping means disposed on opposite sides of the die for gripping the margin of the sheet to be stretched and means providing relative movement between said die and clamping means for stretching and permanently shaping the sheet to conform substantially to the contours of the die surface. An open-topped insulated heating- box 18, having heating elements 20 therein, is mounted on a framework 11 and has a readily removable hollow die A fitted thereon. The die A has a contoured portion 23 of sheet steel, both longitudinally and transversely curved, and depending walls 24 open at the bottom and shaped to fit on to a shoulder 22 of the heating- box 18. If a sheet is to be stretch formed over one portion 62 of a die C, Fig. 5, the other flat portion 23c is backed by insulating material 63 to prevent it being heated. A sheet M of, for example, magnesium or titanium is held at opposed edges between clamping jaws 43a, 436 closed by bolts 46. The clamping jaws are connected by links 44 to a bracket 45 on a support 41 linked at 42 to a draw bar 36. The draw bar 36 is supported on springs 35 and guided by pins 34 secured to channel members 32 carried by arms 31 depending from a rod 29 mounted in bearings 30 in the frame 11. The clamping jaws are thus allowed movement about the axis of the rod 29 to adjust for slope of the die in a direction normal to said axis. The clamping jaws are moved downwards to stretch the sheet held thereby over the die by a pneumatically or hydraulically operated piston rod 48 connected to the draw bar 36 and moving in a cylinder 47 connected to the rod 29. Adjustable guide rollers 50 adjacent the edges of the die prevent creasing of the sheet thereover. A thermocouple 61 just under the surface 23 of the die controls the output of the heating means 20.

Patent GB-369113-A (GB)
Title: Improvements in and relating to date-indicating or registering apparatus
IPC: G04B19/257
Filed: 1931-07-14
Abstract: 369,113. Date - printing apparatus. HAMMARSTRAND, A. T., Diursholm, Sweden. July 14, 1931, No. 20223. Convention date, July 16, 1930. [Class 100 (ii).] A date indicating mechanism which may be used as a date stamp comprises day, month, and year wheels and a driving member having means which serves to advance the wheels, the month wheel being controlled by a deflecting lever moved from the day wheel and by a cam plate adjustable in dependence on the position of the month wheel. The month wheel has twelve notches corresponding to the months and the notches are of different depths corresponding to the number of days in the months. As shown, Figs. 1-4, the driving element consists of a pivoted member 2 actuated once a day under the control of clock mechanism (not shown). The member 2 carries a pawl 4 driving a wheel 5 with thirty-one teeth rigidly mounted on a sleeve 8 provided with a day member disc 9. Pivotally mounted on the member 2 is a finger 14 with a laterally projecting pin 15 adapted at the end of each month to advance a notched wheel 16 and at the end of the year to advance a notched wheel 17. The month wheel 16 has twelve notches corresponding to the months and the year wheel 17 has twelve notches corresponding to twelve years ; these wheels are mounted on sleeves provided with month and year discs 22, 30. As the day wheel is advanced by the pawl 4 the pin 15 is prevented from engaging the month wheel 16 by its sliding movement along the arcuate surface 18 of a pivoted deflecting lever 19. When the month wheel is to be adjusted a pin 20 on the day wheel engages the lower edge 191 of the deflecting lever and raises the surface 18 out of the path of movement of the pin 15. The depth of the notches in the month wheel 16 corresponds to the number of days in the corresponding months and engaging one of the notches is a pin 27 projecting from a pivoted lever 26 provided with a cam surface 28 on which the pin 15 rides. The position of the cam surface thus determines the moment when the pin 15 can enter under the deflecting lever and also the moment when the surface 14<1> of the finger can engage the pin 20 so as to cause a single step or four-step movement for the month of February. The year wheel 17 is smaller than the month wheel 16 so that the pin 15 can only engage with the year wheel when the deep notch 23 on the wheel 16 is presented to the pin. In the year wheel 17 every fourth notch is shallower than the others. Engaging in one of the notches is a pin 34 projecting from a lever 33 with a cam surface 35 similar to cam surface 28. When the pin 27 engages the deep notch 23 on the month wheel and the pin 34 rests in one of the shallow notches the cam surface 35 is raised above the surface 28 so as to compensate for an extra day in leap year. The projecting pins 27, 34 of the levers 26, 33 and a pin 11 on a lever 10 hold the respective wheels in adjusted position as the ends of the levers are formed with serrations engaged by a pin 12 on the driving member when it is in operative position.

Title: Improved packing for parachutes
IPC: B64D17/52
Filed: 1923-08-08
Abstract: 212,511. Th÷rnblad, A. R. March 5, 1923, [Convention date]. Parachutes.-A parachute and its rigging lines are packed in two containers connected together by a device which is acted upon to release the containers from one another, when a developing line connecting the parachute with the aircraft runs out. Figs. 1 and 2 show the manner in which the parachute is packed. The fabric rigging line container 13 is temporarily secured within the upper container 6, while the packing is done, by threading a metal leaf spring, wire, or cord 26, Fig. 2, through slots or holes in the walls of both containers. The rigging lines 2 are coiled within the lower container 13, Fig. 1. around an inwardly projecting horn 18, to the top of which they are connected, and flaps 14 on the container 13 are folded over to form a partition between the two containers. The parachute 1 is folded and inserted within a lower compartment 11 of the upper container 6, which is divided into three compartments 9, 10, 11 by removable fabric partitions. The developing line 12 is fastened to the container 6, the major portion being coiled within the compartment 9 and the remainder within the compartment 10. Flaps 7 at the upper end of the container 6 are closed by passing steel wires 22 attached to the developing line 12, through eyelets on the edges of the flaps. The connecting line 5 which is attached to the rigging lines 2 or to the top of the horn 18, is packed within the horn, and elastic shock absorbers 3, secured at one end to the line 5 and at the other end to the attaching ropes 4, are connected to rings 21 retained in position on fittings 20 by steel wires 15 which pass through holes in the fittings 20. The wires 15 are secured to the developing line 12 at a point between the portions coiled within the two compartments 9, 10, and also pass through grooves or rings on the walls of the container 6, and through rings on the edges of flaps 8 which close the bottom of the container 1. As the fittings 20 are attached to the lower container 13 the wires 15 lock the two containers 6, 13 together. When the packing is completed the leafspring 26 is withdrawn. In operation, the device is secured to the parachutist by hooks 19, and when the jump is made, the wires 22 are first withdrawn, allowing the upper flaps of the container 6 to open and release the developing cord 12. The wires 15 are next withdrawn by the cord 12 when the device has fallen clear of the aircraft, causing the bottom of the container 6 to open, detaching the containers from one another and releasing the rings 21 to permit the connecting line 5 to run out. The containers 6 and 13 now separate as shown in Fig. 4, allowing the parachute to drop out of the container 6 and open before the rigging lines 2 are fully stretched and begin to exert a pull. On account of the load falling at a greater rate than the opening parachute, the load is separated from the parachute system by a safe distance (corresponding to the length of the line 5) before its fall is checked.
