Title: Improvements in or relating to recoil mechanisms for ordnance
Inventor: FUSCALDI SALVATORE
IPC: F41A25/00
Filed: 1960-06-23
Abstract: 1,008,430. Ordnance recoil mechanism. MINISTERO DELLA DIFESA ESERCITO DIREZIONE GENERALE ARTIGLIENA. June 23, 1960, No. 18099/60. Heading F3C. A gun comprises a unit 2, consisting of a barrel 279, slide 280, breech block 281 and nozzle brake 282, mounted for sliding action under recoil upon a cradle 3, the cradle 3 being mounted for sliding action under recoil upon a cradle 4. The cradle 4 is pivotally mounted on a carriage 6 to enable the gun to be elevated. The recoil mechanism restraining sliding movement of the unit 2 relatively to the cradle 3 is mounted in the cradle 3 and comprises a pair of oil-filled cylinders (Figs. 7, 9, not shown) containing pistons having rods, these rods being connected to the unit 2. The pistons have ports controlled by rotary valves and as the pistons move under recoil the valves are automatically progressively closed to restrict the flow of oil through the ports and thus oppose the recoil movement of the unit 2. The movement of the pistons under recoil also compresses springs which act as recuperators and eventually restore the unit 2 to its original position. Compensators situated at the front end of the cylinders serve to compensate for the vacuum set up therein as the pistons withdraw under recoil, by admitting more oil. The recoil mechanism restraining sliding movement of the cradle 3 relatively to the cradle 4 is mounted in the cradle 4 and comprises an oil-filled cylinder (Figs. 14, 16, not shown) containing a piston having a rod connected to the cradle 3. The piston has ports controlled by a rotary valve, this valve, together with other ported valves operating automatically during the recoil action to restrict the flow of oil through the ports to produce a retarding action of the cradle 3 in accordance with a parabolic law. The cradle 4 also supports a pair of spring recuperators (Fig. 17, not shown) which are stressed during the recoil action and return the cradle 3 to its original position upon the cradle 4. A recoil reducing mechanism (Figs. 10, 11, 12, not shown) automatically reduces the length of recoil of the piston in the cradle 4 when the gun inclination exceeds 30 degrees by reducing the maximum area of the valve ports. The several parts 279 ... 282 of the unit 2 are readily detachable from each other to facilitate transportation.

Patent GB-798435-A (GB)
Title: A method of redistributing fluorine throughout a catalyst mass
IPC: C10G45/08
Filed: 1954-06-24
Abstract: Fluorine is redistributed throughout a catalyst mass comprising the oxides of cobalt and molybdenum supported on alumina and containing a small proportion of unevenly distributed combined fluorine by passing steam or steam-containing gas over the catalyst at an elevated temperature, e.g. 700-900 DEG  F., without recycle.  The catalyst may contain 1-6 per cent by weight of fluorine and the uneven distribution may have resulted from hot recycle regeneration of the catalyst, in which the greater part of the combustion products is recycled. During treatment with steam the outlet end of the catalyst mass may be maintained at a lower temperature than the inlet end, for example by commencing with a uniform catalyst temperature and using gas at a higher temperature.  Examples show the effect of varying the steam partial pressure and the space velocity, and of using a steam-containing gas from an inert gas generator in place of steam. The catalyst is suitable for use in the hydrocatalytic desulphurisation of petroleum feedstocks by the autofining process described in Specifications 654,152, 669,536, 669,553 and 697,083. Specifications 719,627 and 747,663 also are referred to.

Title: Demodulating arrangements for frequency modulated electric waves
IPC: H03K9/06
Filed: 1943-11-12
Abstract: 579,671. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. Nov. 12, 1943, No. 18911. Convention date, Nov. 13, 1942. [Class 40 (v)] A frequency-modulated carrier wave 9, Fig. 2, is demodulated by clipping it at the levels 11, 13, differentiating the resulting pulses 10a to produce short pulses 12a alternately positive and negative, and utilizing the pulses 12a to re-constitute square pulses 14a. The re-constitution of the square pulses may be effected in a trigger valve circuit, Fig. 3, having two stable conditions, and being switched from one to the other by the alternate positive and negative pulses 12a. It comprises two pentode valves 22, 24 with anode resistors 50, 52 and control grid resistors 64, 66 and with reciprocal back couplings comprising resistance-shunted condensers 60, 56. The input 12a, Fig. 2, is applied between the cathodes and the suppressor grids 30, 32, and the output pulses 14a are taken from the anode of the valve 24. These pulses are again differentiated to produce the series 16a, Fig. 2, of constant amplitude, and the negative pulses are eliminated by a rectifier to give the series 18a, which is fed to an integrating circuit to produce the modulating signal 21. In a modified arrangement, the series 12a produced by the first differentiation, or the series 18a, are fed to a valve pair (Fig. 5, not shown), the output of which comprises pulses 73 of greater but constant width, which are integrated to produce the signal 21. This latter valve pair is designed with one permanently stable condition to which it returns a determined time interval after being tripped by positive pulses 12a or 18a, thus giving pulses 73 of uniform duration.

Abstract: 833,415. Feeding sheets; sheet-delivery apparatus. NATIONAL CASH REGISTER CO. June 16, 1958 [Aug. 26, 1957], No. 19142/58. Classes 100(1) and 100(4) A mechanism for feeding a sheet, e.g. a cheque or ticket, inserted in machine up to two stops disposed at right angles to each other, includes a driving mechanism and feeding devices driven by the driving mechanism and adapted to feed the sheet in directions at right angles to one another, each device being rendered alternately effective so as to feed the material in stepped increments in the respective directions through frictional engagement until the sheet contacts its related stop. As shown, a sheet, such as a cheque 28, Fig. 4, is placed on a table 27 at random for feeding into registered position above type wheels 26 by two feeding devices arranged at right angles to one another. The feed devices comprise feed rollers 35 and 51, Figs. 1 and 4, provided with hard rubber feeding fingers 36 and 52 which frictionally engage the cheques. The rollers are continuously driven through gearing, not shown, by a vertical driving shaft 39 driven through gearing by an electric motor 60. The fingers 36 and 52 engage the cheque 28 alternately to feed the cheque in steps towards flanges 30 and 29 which register the cheque for printing. Depressions 70 (Fig. 2, not shown) in the table 77, (Fig. 3, not shown) prevent too much friction between the cheque and feed fingers, while the rollers 35 and 51 are vertically adjustable by collars 53 on studs 44. The cheques may be ejected by reversing the direction of rotation of the motor after printing. Alternatively, the cheques may be ejected automatically after printing under the control of a solenoid 76 (Fig. 3, not shown) which is energized after printing to rock a shaft 79 through a bell-crank lever 78 carrying a feed roller 80, thereby rocking the roller 80 into engagement with a feed roller 81 on a shaft 103. The shaft 79 also carries a roller 88 on an arm 75 which is rocked into engagement with a feed roller 89. The feed rollers 81 and 89 are driven by a shaft 103 through a shaft 66 driven by the motor 60. A further bell-crank lever 84 (Fig. 3, not shown) on the shaft 79 raises a frame 38 carrying the feed rollers 35 and 51 upon energization of the solenoid 76, thereby causing these rollers to disengage the cheque ejected by the rollers 80, 81 and 88, 89.

Title: An improved carburettor for internal combustion motors
IPC: F02M9/14
Filed: 1920-07-08
Abstract: 147,517. Genestin, P. Oct. 8, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Spray carburettors are provided with a suctionactuated tubular member 13 having an enlarged extension 14 to control the passage of air around a fixed choke-tube 20. The suction in the carburettor body below the throttle valve 7 acts upon the internal surface of the member 13, whilst the suction above the throttle is transmitted to a chamber 2 and the shoulder on the extension 14 through orifices 9, 9<a> in a flange 8 on the throttle valve, and passages 10, 12 in the casing 1. The chamber 2 communicates with the atmosphere through a small orifice 3. The fuel nozzle 21 contains an internal tube 22 communicating with a passage 23 open to the atmosphere at the level of the nozzle orifice. A slow-running nozzle 26, controlled by an adjustable tube 17, supplies mixture to an outlet 16 above the throttle valve. At starting, the member 13 is lifted by the suction through the passage 10, and fuel is supplied by the slow-running nozzle 26 only. As the throttle is opened, the passage 10 is closed, the member 13 falls, and the fuel from the nozzle 21 is atomized by the air passing through the choke tube 20, the fuel accumulated in the tube 22 and passage 23 furnishing a rich mixture for accelerating. Further opening of the throttle again opens the passage 10, the member 13 rises, and air passes both around and through the choke-tube 20 and also through the passage 23 and tube 22.
