Title: Improvements in or relating to storage and transport vessels for liquefied gases
IPC: F17C3/10
Filed: 1930-04-29
Abstract: 351,158. Cold and heat retaining vessels. SOC. L'AIR LIQUIDE SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE, 48, Rue St. Lazare, Paris. April 29, 1930, No. 13225. Convention date, April 30, 1929. [Class 29.] A vessel for storing and transporting liquefied gases is formed with a jacket containing solid insulation lying in an atmosphere of gas automatically maintained between controllable limits. The liquid container 1 is suspended from the outer sheath by chains 4 and has a discharge pipe 5. A pipe 10 having a safety valve 6 and a metal foil disc 7 conveys a part of the evaporating gas to the space containing magnesium carbonate or other solid insulating material. The gas passes through a valve 11 so long as the pressure is not above say 5 cm. of water. If the liquid container is empty and the pressure in the jacket rises by heat influx over say 10 cm. of water, the gas is discharged through a valve 13. A disc 8 is attached to the outer sheath by a thin rubber membrane 9 and becomes loose under a determined excessive pressure. The Specification as open to inspection under Sect. 91 (3) (a) states that the container 1 may be prevented from rising in the outer sheath by tierods &c. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to shock absorbers particularly for automobiles
IPC: F16F9/28
Filed: 1932-05-07
Abstract: 391,978. Hydraulic shock-absorbers. ARMSTRONG, F. G. G., 14, York Road, Beverley, Yorkshire. May 7, 1932, No. 13226. [Class 108 (iii).] An hydraulic shockabsorber comprises a pair of chambers and means for pumping liquid from one chamber into the other on actuation of the shockabsorber, liquid being introduced into one chamber during the suction period therein, corresponding to the impact stroke of the shock-absorber, in excess of that which can be accommodated in the other chamber on the rebound of the shock-absorber. As applied to automobiles a pair of interconnected cylinders 8, 9 are pivoted on plugs 10, 11 secured to a reservoir casing 3 connected by a link 24 to an axle of the vehicle and rotatably mounted on a pin 1 fixed to the vehicle frame, the plungers 6, 7 of the cylinders being connected to, or abutting, the ends of a double-armed lever 4, 5 rigid with the pin 1. In the construction shown in Fig. 1 the lengths of the arms 4, 5 are unequal; in a second construction the cylinders 8, 9 are of different diameters ; and in a third construction the ends of the plungers are rounded and one end abuts a cam surface on one of the ends of the lever 4, 5 so that this plunger moves more quickly in its cylinder than the other. In operation if the link 24 is moved downwardly liquid is forced from the cylinder 4 through a passage 13, regulatable needle-valve 17, Fig. 4, and passage 21 to the cylinder 8 whereas if the link 24 is moved rapidly upwardly, the capacity of the cylinder 9 being greater than that of the cylinder 8, a vacuum is created above the pistonhead in the cylinder 9 and liquid is drawn into this cylinder through lower apertures 25 and through a one-way valve 26 in the pistonhead, in addition to the liquid pumped into the cylinder 9 from the cylinder 8 through the passages 21, 15, 14, 13. Normally, the excess liquid leaks away before the return stroke is completed, but a heavily-loaded non-return valve 31 controlling a small orifice 32 in the plunger 6 may be provided to release liquid when the pressure reaches a predetermined value. Reference is made in the Provisional Specification to Specification 366,167.

Abstract: 496,186. Pneumatic dispatch-apparatus. TELEPHON - APPARAT - FABRIK E. ZWIETUSCH & CO., GES. May 5, 1938, No. 13478. Convention date, Sept. 11, 1937. [Class 78 (i)] In apparatus provided with a sluice chamber and associated suction and pressure pipes for the currents of air driving the carriers through the adjacent tube sections, the sluice chamber is separated from the adjacent tube sections by flaps and accommodates an arresting device, and control contacts are provided whereby the arresting of a carrier is associated with the changing over of the driving air current. Each carrier is stopped in the sluice chamber 3 by an arresting device comprising a clamping bar 19 and a spring-loaded bar 24. The pressure on the bar 24 causes it to yield and close the contact 15, thereby causing the switching over of the coupled three-way valves 12, 13. Compressed air now enters the chamber 3 through the pipe 9 and closes the flap 4 and at the same time opens the flap 5. The opening of the latter closes the contact 17 and thus effects the energization of the electromagnet 18 controlling the bar 19. The latter is withdrawn, and the carrier passes into the adjacent travel tube section 2, where it actuates the travel contact 16 to effect the restoration of the valves 12, 13 to the initial positions as shown. Specification 325,064, [Class 116], is referred to.

Abstract: 541,282. Liquid-pressure engines. INTEGRAL AUXILIARY EQUIPMENT, Ltd., and PACKENHAM, E. W. Aug. 28, 1940, No. 13560. [Class 69 (ii)] In motors of the kind comprising a revolving cylinder-block provided with pistons having rollers co-operating with cam-trucks the rollers are mounted on inwardly cranked parts of arms mounted on the outer ends of the pistons, the arrangement enabling the diameter of the motor to be greatly reduced. The motor may be provided with reversing-valves, and relief valves for preventing the pressure in the cylinders from falling below that in the motor-casing during stopping of the motor. In the engine shown in Figs. 1 and 5, a block 14, formed with cylinders 23 containing pistons 24, is secured to one end of an output shaft 16 and runs on a stationary shaft 20. Each piston is formed with a slot in which is secured, by means of a pin 27, an arm 26 having inwardly cranked ends 28 carrying on roller-bearings 29 rollers 30 which co-operate with elliptical cam-rings 32 fixed in a casing 10. Inner cam-rings 33 may also be provided. The cylinders are formed with ports 44 for communicating with ports 43 formed in the shaft 20 and communicating through longitudinal passages 37, 38, Fig. 5, with chambers 39, 42 respectively. A slidable control-valve 47 is arranged between a pressure inlet 45 and an exhaust outlet 46, and is coupled to a rotatable control-rod which projects from the casing. When the control-valve is moved towards the right, Fig. 5, ports 53, 49 are placed in communication, pressure-oil flows through a passage 60, the chamber 42 and the passages 38, and the engine runs forwards. Exhaust takes place through the passages 37, chamber 39, a passage 61, a port 50, and the outlet 46. When the control-valve is moved towards the left, ports 53, 50 are placed in communication, pressure-oil flows through the passage 61, the chamber 39 and the passages 37, and the engine is reversed. Exhaust takes place through the passages 38, chamber 42, passage 60, port 49 and holes 64 to the interior 66 of the casing, and thence through holes 65 to the outlet 46. When the control-valve is returned to central position, the ports 49, 50 are shut, and the engine is quickly stopped. During stopping, oil can leak between the cylinders and pistons and through a hole formed in the cylinderblock 14 and communicating with the interior of the casing. Spring-loaded non-return valves 74, 75 are arranged between the passages 60, 61 and passages leading to the interior of the casing. During stopping, one of the valves opens to prevent the pressure in the cylinders from falling below that in the casing, thereby preventing the rollers 30 from tending to leave the cam-ring 32, and permitting the pistons to draw oil into the cylinders.
