Title: Improvements in Mountings for Guns.
Inventor: NORRIS FREDERICK AUBREY
IPC: F41A27/06
Filed: 1917-10-25
Abstract: 129,341. Norris, F. A. Oct. 25, 1917. Tripod and like mounts for machine guns.- Consists in a mounting, especially intended for light machine guns firing at aircraft, designed so that the shoulder-piece of the gun can be maintained at the same height whatever the angle of elevation of the gun. The mounting comprises a vertically rocking arm carrying the gun in trunnions or the like at the rear end and having a counterbalance weight at the front. The arm is pivoted in a cross-head mounted by a vertical pivot at the top of a tripod stand or post. In the construction shown in Fig. 1, a Hotchkiss machine gun is mounted by trunnions at the rear end of an arm 11, 13 at the front of which is an adjustable counterbalance weight 12. The arm is mounted on a transverse pivot 10 on a crosshead 6 adapted to turn for training in a socket 4 carried by a tripod stand 1. A set-screw 16 on the arm acting on a segment 15 on the cross-head, and a set-screw 17 on the socket acting on the pivot of the cross-head 6, enable the elevating and training movements of the arm to be frictionally restrained. A fixed or adjustable stop 19 on the arm limits the angle of fire of the gun relatively to the arm. Fig. 6 shows a post mounting for a Lewis gun which is carried by a service band clip 23 at the rear of the arm 11. A number of cartridge drums constitute the counterbalance weight.
Patent GB-1604173-A (GB)
Title: Fluorinated ion excahnge polymers
IPC: B01J47/12
Filed: 1978-04-19
Abstract: Fluorinated ion exchange polymers which have both pendant side chains containing carboxylic groups and pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency.  They are made by oxidation of flourinated polymers which have pendant side chains containing sulfinic groups, or both sufinic and sulfonyl groups.  The fluorinated polymers which have pendant side chains containing sulfinic groups, or both sufinic and sulfonyl groups, are in turn made from fluorinated polymers which have pendant side chains containing sulfonyl halide groups by reduction with, for example, hydrazine.  Fluorinated ion exchange polymers which have pendant side chains containing -OCF2COOR groups and also pendant side chains which contain sulfonyl groups can also be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic group; and also by treatment of a polymer which contains -OCF2CF2SO3H or salts thereof with a combination of fluorine and oxygen.

Title: Improvements in or relating to anti-theft devices for use with scooters, motor-cycles or cycles
IPC: B62H5/06
Filed: 1953-06-05
Abstract: 760,581. Cycle locking devices. NEIMAN, A. June 5, 1953, No. 15554/53. Class 79(3). [Also in Group XXV] An anti-theft device for motor cycles comprises a lock 3, Fig. I, having a lock bolt 5 for locking a steering head bracket 2 to the frame 6, and a bolt 9 by which the bracket 2 is secured to the steering spindle (not visible in Fig. 1) so that turning the lock to its open position, in addition to unlocking the bracket 2, permits direct manual removal of the bolt 9 upon the clearance therefor being provided by removal of the lock. When the lock 3 is in position in its casing on the head 2, it partly covers the head of the bolt 9. The latter is disposed tangentially to the base of a peripheral groove formed in the steering spindle. This prevents the head 2 from being removed if the nut at the other end of the bolt 9 is removed. On unlocking the lock 3 and removing it from the casing, the bolt 9 can be withdrawn through a recess 10 in the outer wall of the casing. In Fig. 5, a torsion spring 32 tends to rotate the rotor 31 of the lock to locking position, in which a holding member (not visible in Fig. 5) engages a recess 15 in the lock casing, in the locking position of the bolt 5. A further recess 16, similar to the recess 15, but nearer to the outer end of the lock casing, provides for retention of the lock in the casing when in a steering-unlocked position. This prevents accidental re-engagement of. the lock-bolt with the frame 6. The lock is outwardly urged by the action of a spring 17. A detachable stop 19 prevents ejection of the lock from the casing. In Fig. 7, the lock casing 20 is rigidly secured to the head of the bolt 9. In Fig. 9, a tumbler type lock 24 has a recess 24<SP>11</SP> in which a ball 26 is disposed when the lock is in its unlocked position. When the lock is turned to its locked position, Fig. 10 (not shown), the ball 26 rides clear of the recess 24<SP>11</SP> and is projected upwardly so that it obstructs the head 27 of the bolt 9. The locking pin 25 is actuated by a pin 24<SP>1</SP> carried by, and eccentric with, the end face of the lock 24. The pin 24<SP>1</SP> engages a kidney shaped slot, Fig. 13 (not shown) in the pin 25 so that there is 180 degrees of lost motion. This permits of having an operative travel of 360 degrees instead of 180 degrees and thus avoids the need for two sets of tumblers (otherwise the pin 25 would be projected in the first 180 degrees of movement, and then retracted again). In Fig. 11, a projection 29 on the pin 25 engages a recess in a disc 28. This results in the disc 28 being partly projected to obstruct the bolt head 27 when the lock 24 is in its locked position, Fig. 12 (not shown).

Abstract: 355,327. Ventilating and heating systems. NEILSON, T. and MARSHALL, J., 11, Cogan Street, Pollokshaws, Glasgow. May 21, 1930, No. 15605. [Class 137.] In conditioning air for ventilating interiors such as ships' cabins the steam required for heating or humidifying is taken from a relatively high-pressure supply and the whole or a part is caused first to do work in a multiple expansion steam engine or turbine and is then passed out from an intermediate stage to air conditioning apparatus at a pressure higher than the exhaust pressure and sufficient to supply the necessary heat and overcome the resistance of the piping. Steam from a high-pressure supply main 4 passes through a conduit 8 and a speed control valve 18 to a three-stage turbo-electric generator 9, is bled at an intermediate stage and passed through a non-return valve 15 and conduits 10, 6, 7 to the conditioning apparatus 3 where it may heat the air by direct or indirect contact. The heated air is distributed by ducts 11, 12 and outlets 13. When the air is heated by indirect contact with the steam an outlet 24 to a condenser is provided. The quantity of steam passed out from the intermediate stage 9b of the turbine to the conditioning apparatus is controlled in accordance with the pressure in the outlet 10 by means of apportioning valves 21, the remainder passing through the low pressure stage 9c to the condenser. Steam bled from the turbine may be supplemented by steam from the high pressure conduit by means of a reducing valve 5. Reference has been directed by the Comptroller to Specification 295,575, [Class 122 (iv), Steam engines, Regulating &c.].
