Abstract: 178,445. Westinghouse Electric & Manufacturing Co., (Assignees of Foresman, R. A., and Aram, 0.). April 12, 1921, [Convention date]. Grates; mechanical stoking.-The retort units of underfeed stokers are built up of a relatively small number of standardized parts capable of being extended to suit furnaces of different size so as to eliminate large and expensive castings. As shown in Figs. 1 and 6, the retort units are formed by side members 23, 24 with bottom plate members 23<1>, 24<1> supported on angle bearers 18, the side and bottom members being extended, if desired, to suit the length of the furnace by relatively short members 25, 25<1>. The side members 23, 24 and bearers 18 are secured to dumping-grate castings 20, at the sides of which are arranged castings 21, Fig. 5, provided with lugs to support the dumping-grate. Openings 27 in the castings 20 allow for the passage of air through corresponding openings in the dumping-grate. The spaces between the retort units are covered by tuyeres 16. Fuel is fed to the retort units from ram boxes 10, below which are provided deflector plates 15. Each ram 11 is interconnected through a lever 13 and link 14 with agitating-devices 12.
Patent GB-105393-A (GB)
IPC: A43D69/04
Abstract: 105,393. British United S h o e Machinery Co., (United Shoe Machinery Co.). April 10, 1916. Slugging.-A fastener-forming mechanism for slugging-machines for use in the manufacture of boots and shoes is constructed to form simultaneously the head of one fastener and the point of the next fastener, this point comprising a wedgeshaped portion terminating in a thin tip having substantially parallel faces, as shown at f, Fig. 5. The invention is described as applied to a machine of the type described in Specification 6971/98. The wire W is fed through a guide 10 into a throat 6 and is indented by two devices 12, 14 arranged to engage the wire close to the point where it enters the throat. The device 12 is clamped in a stationary holder, while the device 14 is adjustably clamped in a holder 18 fixed to a sleeve 20, which is oscillated by an arm 22 actuated by a cam 26 on the main shaft 28. The throat 6 is secured to a shaft 30, which extends through the sleeve 20 and is oscillated through an adjustable amount by a lever 36 actuated by a cam 44 and formed with teeth which mesh with a toothed block 34 secured to an arm 32 carried on the rear end of the shaft. The cams 26, 44 are timed so that the device 14 and throat 6 are moved simultaneously towards the device 12, and the opposite sides of the wire are notched to approximately the same depth. The movement of the device 12 is then stopped, but the throat 6 continues to oscillate and shears off the wire through its minimum thickness, thereby forming a smooth head to the fastener already in the throat. The fastener drops through the throat, which is then moved forwards to carry the fastener under a driver 8. This movement is effected through a toothed block 50 meshing with teeth on a lever 52, which is actuated from the cam 44 ; the teeth on the lever 36 are wide enough to permit this longitudinal movement of the shaft without breaking connexion with the block 34.

Title: Improvements in or relating to film projection control systems
IPC: G03B19/18
Filed: 1959-03-26
Abstract: 899,279. Kinematograph apparatus. ZEISS IKON A.G. March 26, 1959 [March 29, 1958], No. 10679/59. Class 97(1). In a film projection control system of the kind which includes a rotatably mounted member actuating according to a predetermined switching-programme, associated switches in circuits serving to control different processes in the film projection system, one of the control circuits serves to control drive to the member by means of a self-holding relay, the energizing circuit of which is normally completed through a switch of the relay and the switch of the said control circuit which is actuable by the member, the control circuit including additional switch means to complete an alternative energizing circuit through the relay which by-passes the relay switch when the member breaks the normally completed energizing circuit, so that in operation the member continues to rotate until the alternative circuit is broken by the member, and the member has reached a position in which it no longer affects the switch actuable by the member. In the preferred embodiment, a motor 6 drives a rotatable member or drum 5, having one of its control cams 5<SP>1</SP> arranged to engage a switch 1. During film projection, drum 5 and motor 6 are at rest, but near the end of the film, switch 4 is momentarily closed, and the coil 2 of the self-holding relay is energized, thus closing switch 2b in the said normal relay energizing circuit, and also switch 2a causing the motor 6 to rotate drum 5. When cam 5<SP>1</SP> engages switch arm 1<SP>1</SP>, the normal relay energizing circuit is broken, switches 2a and 2b are opened, and the motor stops; however the arrangement is such that the drum 5 continues to rotate until switch arm 1<SP>1</SP> reaches the position shown in broken line, when the alternative relay energizing circuit is completed through contact b. The switches 2a and 2b are again closed, and motor 6 again drives drum 5 until cam 5<SP>1</SP> releases arm 1<SP>1</SP>. Whilst arm 1<SP>1</SP> returns from contact b to a, due to the spring bias, switches 2a and 2b open, motor 6 stops, and the system returns to the rest position shown. During the period of rotation, the drum can be arranged to actuate associated switch or switches, for example to initiate the operation of another projector. Specifications 850,561 and 899,278 are referred to.

Title: Improvements in or relating to electric resistances
IPC: H01C7/04
Filed: 1946-04-10
Abstract: 612,335. Metal oxide resistors; temperature variable resistors. PHILIPS LAMPS, Ltd. April 10, 1946, No. 11010. Convention date, Aug. 22, 1941. [Class 37] A resistor having a negative temperature coefficient is made by sintering a mixture of FeO-Fe2O3-MgO and AL2O3 in such a manner that the resultant material consisting of a uniform spinel phase is not supersaturated with a second phase when the resistor in use develops a temperature at or above 500‹ C. It is stated that this characteristic may be achieved if there exists in the material a molecular ratio equal to unity between the total quantities of bivalent and trivalent oxides. The starting mixture is so composed that MgO: AL2O3 are in the required ratio and the ratio for FeO: Fe2O3 is adjusted in the material 'according to selected conditions of temperature and partial pressure of the oxygen in the surrounding gas during the sintering process. The sintering atmosphere may be a mixture of nitrogen and water vapour and the cooling may also be effected in this atmosphere so as to preserve the adjusted ratio FeO: Fe2O3. In a specific example the starting mixture comprises MgO and AL2O3 in the required molecular ratio 1 : 1 and iron oxide calculated as Fe3O4. Rods 7 x 8 mm. formed from this material are sintered for 30 minutes at 1570‹ C. in an atmosphere of nitrogen and water vapour and cooled in the same atmosphere. In use such a rod resistor has a resistance of 2500 ohms at room temperature, but at an operating temperature of 500‹ C. the resistance value falls to 13 ohms.

In flight training apparatus of the kind providing for relative motion between a model terrain and the entrance pupil of an optical viewing device so that a trainee has an illusion of motion of the terrain as seen from the viewpoint defined by the entrance pupil, means are provided for simulating the effect of atmospheric mist or haze comprising a screen member having a substantially straight edge and so positioned that its face may form the sky in the scene image and its edge the apparent horizon, the member being so adjustable that its edge can appear controllably diffuse in simulation of the effect of haze or mist. A perspective image of a flat model terrain M is produced on the photomosaic A of a television camera by lens L 1  having an internal stop S of small dimensions. The entrance pupil formed by the stop is transferred forward by a pair of lenses L 2  and L 3  to a position S 1 , which becomes the effective viewpoint of the system. An opaque white screen B is positioned with its lower edge substantially coincident with the true horizon level and is mounted for travel bodily along a line approximating to the horizon viewing direction so that as it approaches the position S 2  the image of its lower edge becomes more and more blurred thus producing a more progressive obscuration of the scene over a larger vertical viewing angle. Means c may be provided for illuminating the face of the screen.
