Abstract: 1278689 Walking doll ROVEX TRI-ANG Ltd 19 April 1971 [28 Oct 1969 20 March 1970] 52818/69 and 13641/70 Heading A6S [Also in Division E2] A walking doll has a second body part, e.g. the upper body 5, rocked from side to side about a horizontal axis 8 relative to a first body part, e.g. the pelvis 4, by a pressure sensitive device 15 pneumatically connected to a manual actuator 17. When the doll is upright the C.G. of the legs is behind the axis 23 about which they are pivoted to the pelvis 4 and the inertia of the upper body 5 is sufficient to rock the pelvis 4 and thus alternately raise the feet from the ground, each leg swing- ing foreward under its own weight when so raised. A cross-piece 10 is connected between webs 11 and 12 on the upper body 5, the webs co-operating with abutments 13, 14 on the pelvis to limit the rocking movement. The pressure device 15 may be a diaphragm, a piston or, as shown, a bellows acting on a rod 16 connected to the piece 10. The actuator 17 is also a bellows. The axis 8 may be displaced to one side of the upper body's 5 C. of G., or a spring may be used to return the part 5 after rocking. Solid weights 29, 38 or water may be included in the head and heels. The feet may have transverse ribs 35, an arm 25, 26 projects from each leg and the two are joined by a pivoted rod 27. The first and second body parts may be inner and outer parts of the doll. The legs are articulated to the pelvis by a bush and spring, Fig. 2 (not shown) co-axial with the axis 23 and urging the leg against a second washer and arm 25, 26. Dimples on the arm and second washer hold the leg and the washer and arm together but permit relative rotation against the spring action.

Title: Improvements in or relating to guns for use on aircraft
Inventor: FOZARD JOHN WILLIAM
IPC: F41A21/32
Filed: 1958-04-29
Abstract: 859,979. Aircraft guns. HAWKER AIRCRAFT Ltd. April 1, 1959 [April 29, 1958], No. 13651/58. Class 92. Relates to an aircraft fitted with a gun having its firing axis offset (usually below) the aircraft's centre of gravity so that the reaction of the gun when firing imposes a pitching movement on the aircraft. According to the invention there is mounted immediately in front of the blast tube 1 a series of spaced gas defecting vanes 4 which, in the case of a gun installed below the centre of gravity of the aircraft, deflect the gun gases vertically downwards to produce a reaction acting in opposition to the pitching movement due to direct gun reaction. The resultant force of the two reactions passes through or substantially through the centre of gravity of the aircraft. The inner part 5 of the vanes are cut away to permit free passage of the projectiles.

Title: An improved apparatus for measuring tensile or compression loads
IPC: G01L1/02
Filed: 1942-09-30
Abstract: 560,499. Measuring forces. ROBERTS, W. H. Sept. 30, 1942, No. 13744. [Class 106 (ii)] In apparatus for measuring tensile or compression loads, a hydraulic cylinder 1 and a piston 4, to convert the load into hydraulic pressure, are combined with a pressure-measuring gauge 18 and means for adjusting the relative positions of the cylinder and piston at the moment when the pressure is being measured. The piston and cylinder are connected respectively to two members transmitting the force, and opposite ends 9, 10 of the cylinder contain hydraulic fluid and are connected through a change-over valve 13 to a reservoir 16 and to a hand-operated reciprocating pump 17. One end 8 of the piston rod controls a contact 20 which is free when the piston is in mid-position, but engages one or other of contacts 21, 22 when the piston is moved, to light one or other of two lamps 28, 29 coloured green and red, respectively, through a reversing switch 23, which is coupled to the change-over valve 13. In use, say for measuring a tensile load, the'fluid in the chamber 10 is put under compression, and as shown is connected to the pump 17. For small movements of the piston, the pressure will be correctly indicated on the gauge 18, but for high pressures, leakage may take place, indicated by movement of the piston and illumination of the green lamp 28, in which case the pump 17 must be operated to restore the piston to mid-position with extinction of the lamp, when the gauge will indicate the true pressure. For compression loads, the changeover valve and the reversing switch should be reversed. An incorrect position of these devices is indicated by the illumination of the red lamp as fluid is forced through the restricted outlet 43 into the reservoir. The invention may be applied to the absorption dynamometer described in Specification 545,152.

Title: Improvements in or relating to polyurethanes
IPC: C08G18/68
Filed: 1969-03-18
Abstract: 1,217,101. Self-extinguishing polyurethanes. DR. BECK & CO. A.G. 18 March, 1969 [19 March, 1968], No. 14065/69. Headings C3C, C3P and C3R. Self-extinguishing polyurethanes are prepared by reacting in the presence of a compound which initiates reaction between unsaturated groups, an unsaturated polyester containing tetrabromophthalic acid residues, at least one compound containing one or more active hydrogen atoms and at least one polyisocyanate. The reaction may take place in the presence of a foaming agent. As an alternative the unsaturated polyester containing tetrabromophthalic acid residues may be replaced by a mixture of a saturated polyester containing tetrabromophthalic acid residues and a halogen-free unsaturated polyester. The reaction mixture may also contain a homopolymerizable or copolymerizable monomeric compound and one or more catalysts for the polymerization and/or polyaddition reactions. Suitably the unsaturated tetrabromophthalic acid polyesters may be neutralized to a low acid number with a compound containing epoxy groups. The compounds containing hydrogen atoms are preferably compounds based on a natural or synthetic fatty acid having 7 to 21 carbon atoms. The unsaturated polyester is suitably based on N - hydroxyalkyl or N - carboxyalkyl - tetrabromophthalimides. In a typical example an unsaturated polyester prepared from tetrabromophthalic acid anhydride, maleic acid anhydride and neopentylglycol is mixed with castor oil, antimony trioxide, benzoyl peroxide and a crude diisocyanate containing 90% of 4,41- diphenylmethane diisocyanate. In similar examples styrene may also be incorporated in the reaction mixture.
