Title: Improvements in or relating to cocks or taps for pressure fluid pipes and containers
IPC: F16K3/36
Filed: 1938-12-05
Abstract: 521,182. Lubricating valves. GERARD, P. E. N., and LANNOY, R. DE. Dec. 5, 1938, No. 35371, Convention date, Nov. 15. [Class 135] [Also in Group XXXIV] A rotary disc valve has the contacting surfaces continuously lubricated by lubricant forced from a reservoir on the valve member or in the valve casing by the pressure of the controlled fluid. As shown in Fig. 1, a disc plate 5 with an eccentric port 6 is pressed by the inlet pressure against a seat 4 formed on a nozzle member 2 screwed into a valve body 1. The nozzle has a port 3 with which the port 6 co-operates. A pivot 8 screwed into the disc 5 is received in a hole 9 and carries an operating rod 12 which works within a slot 10 which extends for preferably 180‹ or more round the nozzle. The lubrication is effected by a substance such as finely divided graphite, paraffin or graphited grease contained in a tube 14 supported on the disc 5 and passing with small clearance into a hollow 18. The body 1 has a depending flange 16 by which air is trapped above the lubricant to which the pressure of the controlled fluid is transmitted without it coming into contact with the lubricant. Lubricant reaches the valve face through an aperture 15. Fig. 4 shows a modification in which the nozzle 2 is formed with a closed chamber 20 divided into two compartments by a partition 24 which extends nearly to the top of the chamber. One compartment communicates by a calibrated passage 26 with the inlet side of the valve whilst a similar passage opening in the other compartment which contains lubricant, opens at the valve face. The passage 26 may be arranged so that the controlled fluid exerts'its influence on the lubricant when the valve is open or closed or during part of its displacement from the open to the closed position or vice-versa.

Title: Improvements relating to apparatus for use in shrinking textile fabrics
Inventor: SCREETON BERTRAM EVERARD
IPC: D06C21/00
Filed: 1956-11-23
Abstract: 866,074. Shrinking fabrics. BRADFORD DYERS' ASSOCIATION Ltd. Nov. 25, 1957 [Nov. 23, 1956], No. 35925/56. Class 42 (1). In a method of shrinking textile fabrics, the fabric is passed from a compressive shrinking apparatus to a Palmer dryer, the shrinking apparatus and dryer being sufficiently close together to obviate the necessity for providing an intermediate supporting surface for the fabric, and their relative speeds being such that the fabric is delivered from the shrinking apparatus at a speed which is slightly less than that at which it travels round the dryer. The fabric 1 is shrunk by compression between a heated roller 2 and an endless belt 3, after which it travels unsupported to the endless belt 8 of a Palmer dryer. The heated roller 2 of the shrinking apparatus is positively driven and drives the drum 6 of the dryer through a chain 11, an infinitely variable gear 7 and a chain 12. Mention is made of the fact that the shrinking apparatus may be of the kind in which the fabric is fed to the nip between two outlet rollers at a speed greater than that at which it passes through the nip, in which case both outlet rollers may be geared to the drum of the Palmer dryer.

Title: Hydraulic telescopic shock absorber
IPC: F16F9/19
Filed: 1974-08-15
Abstract: 1484195 Hydraulic telescopic dampers ITT INDUSTRIES Inc 15 Aug 1974 [20 Aug 1973] 35967/74 Heading F2S A vehicle damper provides a greater resistance to compression and rebound movements when the vehicle is heavily loaded (i.e. when the damper is contracted) than when it is lightly loaded, and the resistances afforded in the heavy load condition are adjustable. Compression movements.-When the piston is above the position shown, compression movements are lightly damped, liquid in the chamber 6 below the piston flowing past a spring-biased valve element 14 to the reservoir 10 as well as through the piston to the chamber 5. When the piston is below the position shown, it closes off access to the valve element 14 and compression movements are more heavily damped, liquid flowing through the piston to chamber 5 and thence to the reservoir 10 via a valve element 8 whose spring bias is greater than that of the valve element 14, and adjustable. Rebound movements.-When the piston is below the position shown, rebound movements are heavily damped because passage 22 is covered by the piston and liquid can flow from the chamber 5 only via the heavily biased adjustable valve element 8 to the reservoir 10. When the piston is above the position shown, the passage 22 is uncovered and rebound movements are only lightly damped, liquid in chamber 5 flowing to chamber 6 past a valve element 21 whose spring bias is less than that of valve element 8. The chamber 6 is replenished by liquid flowing from the reservoir past valve element 19. Other details.-The piston is tapered to provide a gradual transition between light and heavy damping for both compression and rebound movements. Each of the damping valve elements 8, 14 and 21 have a permanently open path in parallel with them. Figs. 1 and 2 (not shown) are diagrammatic representations of dampers. Fig. 2 is similar to Fig. 3 with three damping valve elements 8, 14, 21 and two non-return valve elements 12 and 19, but the valve element 12 is in an external by-pass rather than in the piston. Fig. 1 has four damping valve elements 8, 14, 17, 21 and two non-return valve elements 12 and 19, the adjustable valve element 8 being used only for rebound movements and the adjustable valve element 17 being used for compression movements.
