Abstract: 121,342. Harris, G. H. Dec. 12, 1917 Ball and float valves; pressure-regulating valves. -A pressure-regulator of the kind comprising a tank divided into two compartments by a partition, which stops short of the bottom, and containing a volume of liquid adapted to actuate an inlet valve through a float mechanism, has one surface of the liquid exposed to the gas pressure, while the other is subject to the pressure of air compressed in the space above it. In the form shown, floats K, K<1>, one in each compartment, are adjustably secured by clamps k<3> to vertically guided rods pivoted at their lower ends to the opposite ends of a lever G pivoted to the casing and connected by a link F' to a crank-lever F adapted to actuate the inlet valve E. A pump N is provided for compressing air received at L through a check valve S and three-way cock T into the compartment B; or it may be used for introducing liquid received at M. By throwing over the cock T, the pump may be used to spray air or liquid into the gas chamber A. In a modification. a single hinged float is used to actuate the valve.

Abstract: 1,059,773. Selective punching apparatus. BELL PUNCH CO. Ltd. Aug. 4, 1965 [May 5, 1964], No. 18627/64. Heading B4B. [Also in Division G4] A token plate 3 is sensed by a plurality of members 6 attached to racks 4, the members 6 and racks 4 being moved over the plate 3 by means of a driving member 8 which is coupled to a cam 16 through a linkage 12, 15. When a member 6 reaches an aperture in plate 3, it is pushed into the aperture by driving member 8, and the associated rack 4 remains in this position. The end of each rack 4 is thus positioned over the appropriate one of punch members 33 and the latter effect punching when the punch unit is raised by further movement of cam 16 and linkage 21a, 20. The punch block has an upper and a lower part each comprising a pair of plates, one plate having columns of apertures and the other plate having slots corresponding to the columns of apertures. The punch members 33 pass through the upper and lower parts of the punch block and are held in the punch block by members which pass through slots in a row of punch members 33. The die block comprises an apertured plate and a pair of closely-spaced slotted plates. A stripper plate comprising an apertured and a slotted plate is mounted between the punch and die blocks.

Title: Improvements in or relating to compressed air systems
IPC: F16K31/165
Filed: 1961-05-24
Abstract: 977,084. Apparatus for releasing liquid from compressed air systems. REGIE NATIONALE DES USINES RENAULT. May 24, 1961 [July 4, 1960], No. 18745/61. Heading F4U. [Also in Division G3] A device for automatically draining condensation water from a compressed-air system comprises a chamber 12 in which the condensate collects during the time that the system is operative and from which it is discharged when the system becomes inoperative, the inlet port 14 and discharge port 16 for condensate being opened and closed by means actuated independently of the air pressure prevailing in the system. Such means may, in a compressed-air system associated with a motor vehicle, comprise a piston 17 actuated by an electromagnet energized by the ignition system, or by movement of a diaphram 27 in response to oil pressure in the lubricating system. Fig. 2a shows the system in its operative state in which the piston 17 has been moved downwardly by the diaphragm 27 so that the condensate discharge port 16 is closed by a valve 15. At the same time the chamber 12 is connected into the system when the port 14 from the compressed-air reservoir 2 is uncovered by the lifting of valve 13. The system also includes a load line 7 containing a non-return valve 37 which opens as the chamber 12 is pressurized. Fig. 2b shows the system in its inoperative state as for example when the vehicle engine is switched-off, whereupon the diaphram is moved upwardly by spring 29. The consequent upward movement of piston 17 closes the port 14, so isolating the chamber 12 from the airstorage reservoir 2, and opens the port 16, thus releasing from the chamber 12 any accumulated condensate. The reduction in pressure in chamber 12 causes closure of the non-return valve 37 so preventing loss of air from the system. Specification 939,414 is referred to.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec, 29, 1934]. [Class 108 (iii)] A motor vehicle spring shackle comprises a roller having a free translatory movement between concave or straight guides mounted on the spring and chassis respectively. The main leaf of the spring may form one of the guides. As shown in Fig. 1, the end of the main leaf 6 of the spring passes between the roller 16 and a cross-piece 11 and may be straight or curved upwardly to engage in a recess 12 on a support 1. Alternatively the spring may pass beneath the lower end of the support and its end may be curved backwardly through the support. Resilient pads 13 may be provided in the recess 12 and between the spring and cross-piece 11. In order to apply the invention to existing leaf-springs, a fitting 31, Fig. 2, may be secured to the end of the spring by means of a U-shaped bolt 38 and a bolt 36 connected with the spring-eye. The lower end of the support 1 bears directly on the roller 16 which has end flanges 17 to prevent lateral relative movement. The support comprises adjustable toothed arms 23 pivoted at 24 to the chassis and coacting with toothed locking links 26. Alternatively each arm 23 and link 26 may be rigid with the pivot 24 and the end of the link adjustable in a slot 30 in the chassismember 2.

[Class 97 (iii)] A self-erecting gyro vertical for aircraft comprises a pendulous outer gimbal ring pivoted for 360 degrees freedom, a non-pendulous inner gimbal ring pivoted for limited freedom in the outer ring, and a single gyro rotor carried by the inner ring. As shown in Fig. 2, a rotor 16 universally mounted in gimbal rings 13, 10, non-pendulous and pendulous respectively, is spun about a vertical axis by air directed from a nozzle 25 on to buckets 26. A climb indicator card 30 is attached to the outer gimbal ring 10 and is read in conjunction with the customary level lines 34, Fig. 7. A bank indicator bar 33 carried by the inner gimbal ring 13 displays the angle of bank. A representation 31 of an aeroplane constitutes the zero point of the climb indicator. The indications shown in Fig. 7 are the result of a climbing turn to the right. A stop 18 on the inner gimbal ring 13 arranged to engage an arm 19 on the outer ring 10 prevents complete upsetting of the rotor and ensures its return to original position with its indicating elements, after manoeuvres of the craft. If the inner gimbal ring 13 wanders relative to the outer gimbal ring 10 it is precessed back 'to the normal position by the impact of the driving air jet upon the sides of the buckets. A directional gyroscope 46 carries on its vertical gimbal ring 40 a toothed ring 52 gearing with a compass card 54 which gives azimuth readings against a lubber line 57. The compass card may be raised out of gear and manually set by pushing-in and rotating a knob 58.
