Title: Improvements in antidazzle devices
IPC: B60Q1/14
Filed: 1932-08-04
Abstract: 392,028. Antidazzle screens ; goggles. CHILOWSKY, C., 15, Rue du Lunain, Paris. Aug. 4, 1932, No. 21911. Convention date, Aug. 7, 1931. [Class 103 (ii).] In antidazzle apparatus particularly for the use of vehicle drivers the eyes are protected by a screen moved into position by electromagnets, servo-motors, &c. controlled by one or more light-sensitive cells, for example of selenium, an alkali metal or copper oxide, so situated as to be affected by the same variations of the lighting which affects the eyes and to be shaded by the motion of the screen to protect the eyes. The cell 14, Fig. 4, mounted on the head of the driver or secured to the vehicle forms part of a Wheatstone Bridge circuit including a relay 24 and electromagnet 25 acting on a slotted plate 26 to which the screen 21 is connected, the rotating shaft 28 of an electric or other motor 29 engaging in the slot 27 so that when the plate under the influence of the magnet or of a return spring 30 is brought into contact with the shaft, the screen is raised or lowered. The breaking and making of the circuit owing to the alternate shading and uncovering of the cell produces an oscillating motion of the screen in its operative position. The screen may be enclosed in a glass case and may be mounted on the vehicle windscreen which may form the outer face of the case. In a modification the magnet acts on one end of a lever fixedly pivoted between the ends, the other end of the lever acting on an antidazzle screen slidable on a fixed rod. In another form, the screen 4, Fig. 2, is secured to arms 4<11> pivotally mounted at 9 on goggles 8 or the like on the head of the driver, the arms being acted on at their ends by magnets 10 in circuit with the cell 14 or cells 14<1>. The screen may be moved horizontally or vertically or, under the action of two cells adapted to control two groups of operating devices, the screen may be moved horizontally and vertically. The light falling on the cell or cells may be concentrated by a concave mirror or by a lens.

Title: Improvements in or relating to letterpress printing machines
IPC: B41F1/44
Filed: 1932-08-04
Abstract: 397,665. Printing; ink-ribbon mechanism. WRIGHT, J. S., 268, Kenning- ton Road, London. Aug. 4, 1932, No. 21916. [Classes 100 (iii) and 100 (iv).] A device for producing facsimile typewrittenmatter in an ordinary letterpress-printing machine, without alteration or special construction of the machine, comprises an ordinary printers' chase on which is mounted an ink ribbon and traversing-means therefor. The ink ribbon 4, Fig. 5, is unwound from tubes 5 which are mounted on pins 6, 7, Figs. 1 and 3, rotatably mounted on links 2 which slide in grooves 1a in the side members of the chase 1. The pins 6 are accommodated in open slots 1b in the side members and are held in position by clips 3, so that the ribbon may be removed by lifting the clips 3 and raising and sliding sidewise the tubes 5. The pins 6, 7 are frictionally gripped in the ends of the tube 5 and have small pins 6a engaging small notches 8a therein. The ribbon is held to the tubes by a rod 4a, which is passed through a longitudinal slot 5b in the tube. Gear wheels 8 are loosely mounted on the pins 7 and have spring-pressed pawls 8a, Fig. 7, engaging ratchets 9 keyed to the pins. Ratchets 10 also keyed to the pins 7 and pawls 10a mounted on the chase prevent reverse rotation of the tubes. The wheels 8 are rotated by racks 12b mounted on plungers 12, sliding in the side members and depressed by the platen against the action of springs 14. The links 2 are of such length that only one wheel 8 is engaged at once, and when the ribbon is fully wound in the corresponding direction, the pressure of the ribbon against springs 15 pushes the tubes and links longitudinally of the frame, disengaging one gear 8 and engaging the other. The links are held in either position by spring detents 2b. The ribbon can be removed or changed without disturbing the locked-up type.

Title: Improvements in or relating to planting and sowing machines
IPC: A01C9/06
Filed: 1935-08-03
Abstract: 465,512. Planting-machines; distributers for seeds. MARTINOVSKY, F. Aug. 3, 1935, No. 22091. Void. Convention date, Aug. 4, 1934. [Class 6 (i)] A planting and sowing machine comprises a jaw moved up and down in the machine and a rocking jaw moving with it and arranged to approach it and to recede from it periodically. The jaw 1 is provided with a member 14 sliding on guide rods 15 and is actuated by the curved limb 17 of a double lever provided with a roller 118 running on a cam 23, the limb 17 passing through a guide member rotatably mounted in an extension of the member 14. The jaw 2 is pivoted on a pin 3 and is urged towards the jaw 1 by a spring 11. It is normally held back by a spring-controlled pawl 5 engaging a pin 4 on the jaw. When the jaws descend the pawl 5 strikes a stop 9 and releases the jaw 2. When the jaws rise a projection 10 strikes a screw 12 and swings the jaw 2 back into position for the pawl 5 to re-engage the pin 4. When the machine is used for planting potatoes a blade pivoted on a pin 36 and passing through a rotatably mounted guide swings under the jaws as they rise. A channel leads from a container to the machine casing and the potatoes &c. are moved along it by forks 28 passing through slots and carried by a link actuated by the cranks driven by chain gearing, the forks releasing the tubers from the pressure of a spring. The potatoes are released by the jaws in their uppermost position and pass to a furrowing share, For sowing seeds the forks 28, and the pivoted blade are put out of operation and the channel replaced by a channel 124, Fig. 3, provided with a sealing member 125 and link 127. The seeds lifted by the pins are delivered into a receptacle 132 and discharged by it to a furrowing shoe. The receptacle is moved into position periodically by a double lever 131 and cam 128. The jaws 2 may consist of a number of independent parts connected by a removable pin. The parts may be operated independently so as to open and close one after the other. Separate small bowls or buckets may be connected to the independent jaw parts for sowing seeds, and one large bowl to the jaw for planting potatoes &c. The opening of the seeds may be varied by changing the gearing or by attaching bowls to some only of the jaw parts. Several planting and sowing units may be mounted on one machine, one crank-mechanism and one pin for connecting the receptacles 132 being employed.

Patent GB-190755-A (GB)
Title: Improvements in and relating to thermostatic controlling devices
IPC: G01K5/68
Filed: 1921-08-24
Abstract: 190,755. British Thomson - Houston Co., Ltd., (General Electric Co.). Aug. 24, 1921. Thermostats.-In a thermostat of the type in which, to change the temperature setting, a bimetallic strip is subjected to an initial stress in opposition to the stress set up therein by expansion, the element is in the form of a relatively flat member, one end of which operates an electric switch or like device controlling the heat supply. In order to prevent excessive strain in the thermostatic element when the temperature exceeds the predetermined value or a high temperature setting is being effected, the element 11, which co-operates with a snap switch 15, is secured to a rotatable shaft or support 12, between which and the adjustable elements 14, 18 for varying the temperature setting a slip connection is provided. In the construction shown, the slip connection comprises a spring-pressed ball 20, Fig. 3, which is mounted on a flange 19 secured to the shaft 12 and is adapted to engage a depression 22 in the face 17 of a regulator arm 14 to which is attached a bushing 18 located in the wall 10 of an oven or the like. When the temperature of the oven is in the neighbourhood of the temperature to which the arm 14 is set, the shaft 12 also remains stationary and the bimetallic strip 11 moves either to the left, Fig. 2, to open the switch 15 or to the right to close the switch according as the temperature is above or below the predetermined valve. Should a further rise in temperature occur after the switch 15 has been opened, the strip 11 is put under strain until it exerts a torque on the shaft 12 sufficient to overcome the clamping friction of the ball 20, which passes out of the depression 22 and leaves the shaft 12 free to rotate. Similarly, when the current supply to the oven is broken at a main switch, the oven cools and the switch 15 is closed, and finally the shaft 12 is disengaged and rotates freely; on again closing the main switch, the shaft 12 rotates in the opposite direction as the oven heats up until the ball 20 springs into the recess 22, after which the thermostatic control again becomes operable.

Title: Reduction of iron oxide ores
Inventor: ROBIETTE ALFRED GORDON EVANS
IPC: C21B13/02
Filed: 1965-05-27
Abstract: Finely divided iron ore is mixed with finely divided medium to strongly caking coal and formed into pellets which are charged to a shaft furnace in which they are heated to such a temperature by upwardly flowing gases that the coal is carbonized and the ore partially reduced.  The pellets then pass over a discharging edge at the base of the shaft, and fall out of contact with air to a furnace containing a turbulent bath of iron and slag where reduction of the ore is completed.  The shaft may take the form of an annular kiln the vertical axis of rotation of which is offset from the centre of a circular discharge aperture in a stationary base, or may take the form of a stationary annular kiln from the base of which the pellets are removed by a rotary scraper.  In yet another form the walls of the kiln are stationary while the base oscillates.  The pellets as discharged from the shaft may contain carbon in excess of that required for final reduction, this excess being used to provide heat for final reduction and melting by combustion with a jet of air or oxygen.

Title: Improvements in and relating to the manufacture of compositions containing wood fibre
IPC: D21J1/00
Filed: 1929-07-23
Abstract: 316,224. Kayser, O. July 25, 1928, [Convention date]. Boards; suction apparatus. - Sheets, suitable for artificial wood, and capable of use as a base for veneers, are formed from wood pulp with or without the use of binders or fillers. The pulp in a comparatively viscous condition and containing 5-12 per cent of fibre is fed positively to a sieve or filter roller under suction of half an atmosphere, or great enough to cause a proportion of the pulp fibres to stand on end and so produce more complete felting. The felting may be assisted by the use of an agitator or shaker immediately preceding the sieve surface. When a layer of the required thickness is obtained, it is removed from the suction surface, passed through felt covered rollers to absorb the remaining moisture, then cut into sheets and dried. Suitable apparatus consists of a suction cylinder 2 to which the viscous pulp is fed by a conduit 1 by virtue of a head of 5-6 metres, the drum being in part covered by a web. The uncovered part may be at atmospheric pressure or at a small increased pressure. The sheet is removed by a scraper 4 and led on a carrier device 5 to the cutting machine.
