Title: Improvements in or relating to artificial horizons for aircraft
IPC: G01C19/44
Filed: 1947-01-02
Abstract: 629,305. Gyroscopic apparatus. FLOREZ, L. DE. Jan. 2, 1947, No. 188. [Class 97 (iii)] The movement of the horizon which appears to take place when an aircraft is turned is simulated in an artificial horizon indicator by causing patches of light to move along the indicator, the movement of the patches being caused by a directional gyro. The horizon bar 14 of an altitude gyro 11 is illuminated by light beams, rendered parallel by a condensing lens 41, produced by a lamp 25 which is mounted so as to extend into a rotary drum 33 through slots in which the light rays pass. The drum is driven by bevel gearing from the trunnion of the vertical ring of a directional gyro 23. The horizon bar 14 is of square cross-section and set at an angle to reflect the incident beams out through the dial of the instrument, the beams forming light and dark areas 42 on the bar. When the aircraft turns the drum 33 is rotated by the directional gyro and the light and dark areas move across the horizon bar in the same sense and at the same rate as land - marks would appear to move to the pilot across the real horizon. In a modification the casings of the altitude gyro and the directional gyro are provided with an intercommunicating air-passage.

Title: Improvements in means or apparatus for delivering predetermined measured quantities of liquid
IPC: G01F11/10
Filed: 1921-01-04
Abstract: 177,614. Butt, E. E. W. Jan. 4, 1921. Moving-chamber apparatus of the kind in which a tilting device with a rocking movement has tubular collecting and discharging arms which are connected by a tubular conduit constituting a measuring-chamber, has the measuring-chamber 1 formed with an adjustable overflow port 6 through which escapes into bulk the excess liquid picked up by the dipper 4 carried by the arm 2 communicating with the measuring-chamber. The device is pivotally mounted at 5 on a bracket arm 16, and as the dipper is moved back to pick up a fresh supply of liquid from the tank 20 the measured volume of liquid contained in the tube 1 is discharged through the pipe 7. The size or height of the orifice is regulated to adjust the volume of the measured quantity by moving a slidable sleeve 11 over the port 6 formed in a tube 9. This sleeve member contains cork packing 12 to ensure a fluid-tight joint.

Title: Improvements in the manufacture of filled and closed bags
Inventor: GILBERT JOSEPH ARTHUR
IPC: B65B51/04
Filed: 1955-01-05
Abstract: 784,232. Packaging-machine. ROSE BROS. (GAINSBOROUGH), Ltd. Jan. 4, 1956 [Jan. 5, 1955], No. 305/55. Class 94(1). [Also in Group XV] Apparatus for closing filled bags includes means for constricting the neck and applying to it a tag held in position by a metal clip bent to enclose the neck and a portion of the tag. The bags 11 which may be formed and filled by means as described in Specification 758,365 are carried in pockets 12 on an intermittent conveyer 13 to the closing position, having previously had their mouths distended in known manner. The bag mouths are gripped by jaws 16 and an arm 33 swings about a pivot 31 to bring spaced pairs of neck forming blades into a position where they close together to form the bag neck, Fig. 6. The material 130 for the clips is fed from a roll to a position opposite a forming member 128 carrying a knife blade 141. The tags 146 are held in a magazine 59 from which they are removed individually by a suction member 62 and held between the strip 129 of the material 130 later to form the clips and the bag neck A forked support 94 advances to embrace the neck and enters opposed notches on the tag 146, thus locating it and permitting the member 62 to withdraw. The member 128 now advances to meet the support 94, its knife 141 cutting off the clip 129 which is bent to U-shape by the extremities of the elements 94, 128. The support retreats, followed by the member 128 so that the clip embraces the bag neck with the tag between. The support 94 draws clear and fingers 109, 111, swing in in succession to fold the arms of the clip round the bag neck. The various elements restore themselves to their original position and the completed package is removed by the conveyer 13.

Title: Improvements in or relating to electromagnetic switching devices
IPC: H01H51/08
Filed: 1934-01-05
Abstract: 431,349. Selectors for distant-control systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and WOODLAND, C. R., 45, Warnerville Road, Broadgreen, both in Liverpool. Jan. 5, 1934, No. 452. [Class 40 (iv)] [See also Group XXXVII] An electromagnetic switching device suitable for operation by superimposed highfrequency alternating current as, for example, in the system described in Specification 427,109, [Group XXXVIII], comprises an operating coil controlling switch contacts, a dry rectifier in circuit with said coil and a small condenser in series with both, the said components being compactly mounted in a housing comprising a base and a readily detachable cover so as to form a convenient and readily-handled unit. The switching device may have a cam shaft rotated by pawl- and-ratchet gear from the operating coil, the cam or cams engaging and operating suitable contact springs during their rotation. As shown in Figs. 1 and 3 the stepping switch together with a dry-surface rectifier 29 and a condenser 30 are mounted together on an insulating base 31. The switch has an energizing coil 7 and armature 2 pivoted at 3 to a bracket 4 secured to the yoke 5, the arm 7 attached to the armature carrying a pivoted pawl 8 adapted to step round a ratchet wheel 9 attached to a contact-operating shaft 10. The movement of the pawl is limited by an adjustable eccentric stop 13 and return movement of the ratchet is prevented by a pawl 14 connected by a spring 16 to the pawl 8. The shaft 10 carries cams 21, 23, Fig. 4, adapted during its rotation to operate contact springs 23 in controlled circuits, the arrangement being such that there are three operative positions corresponding to both contact springs open, one spring closed and both springs closed. The connections to the relay and associated apparatus are brought to plugs 35 mounted in the underside of the base 31 so that the whole forms a detachable unit which is normally plugged into sockets carried by the base 36. The operated contact springs 23 carry rollers 24 by which they are operated from the cams 21, and also carry magnetic armatures 27, 28. These are normally positioned between the poles of a C-shaped permanent magnet 26 so that the contact pressure is re-inforced magnetically, but when the contact springs are moved by the cams to break contact the armatures 27, 28 move rapidly out of the sphere of influence of the magnet to ensure a progressive reduction of pressure on the cams while at the same time a magnetic blow-out effect is produced at the separating contacts.

Title: Improved manufacture of colloidal graphite suspensions
IPC: C10M103/02
Filed: 1934-01-09
Abstract: Colloidal graphite suspensions, particularly for use as lubricants, are obtained by mixing graphite with a liquid binding agent, preferably a thinly fluid mineral oil, but more viscous materials can be used, to form a paste which is then triturated under a pressure of 1 to 2 kilograms per square millimetre in roller mills with surface trituration.  Single roller mills with a movable triturating bar may be used, and the bearings of the triturating roller may be relieved of pressure by counterbalancing with another triturating bar. Several rollers may be placed one above the other.  Multiple roller mills may also be used and in this case, the outward longitudinal curvature of the rollers is increased from about 10 m  to 50 m , and the rollers may be given different speeds.  Preferably, ground graphite is first mixed with blown or thickened fatty oils or with mineral oil-soluble castor oil and left to swell for several hours before grinding. Other materials, such as pigments, clays and soot, may be converted into colloidal form by trituration or in admixture with graphite in the above described manner.ALSO:In the preparation of colloidal graphite suspensions by trituration of a paste of graphite and a liquid binding agent such as oil under pressures of 1 to 2 kgm. per square millimetre with surface trituration, single roller mills with a movable triturating bar may be used and the bearings of the triturating roller may be relieved of pressure by counterbalancing with as another triturating bar.
