Title: Improvements in hydraulic shock absorbers
IPC: F16F9/46
Filed: 1949-03-30
Abstract: 664,770. Hydraulic shock - absorbers. WOODHEAD - MONROE, Ltd., and ONIONS, J. W. May 17, 1950 [March 30, 1949], No. 8681/49. Class 108(iii) In a direct-acting hydraulic shock absorber, the valve of a valve-controlled auxiliary or byepass port within the hollow piston rod is adapted to be operated by an electro-magnet, which is carried by the piston rod and is adapted to be energized by connection to an electric circuit and remote operating switch. In the construction shown in Fig. 1 (Comp.), an inverted cup-shaped valve 50 controls flow between ports 58 and 59 in an extension 57 of the piston rod 53. The ports 58 open into the cylinder space above the piston (not shown), while the port 59 leads via a non- return valve 60 to the cylinder space below the piston. Within the piston rod 53 is a soft iron core 54 surrounded by a solenoid 54a the leads of which (not shown) extend through the end cap and securing ring of the shock absorber, and are connected with a suitable electrical circuit which includes a switch operable by the driver. The solenoid is retained by a bronze gland 56. The valve 50 may be downwardly loaded by a light spring (not shown). In operation the passages 59, 58 (when the solenoid 55 is energized to raise the valve 50 )provide a byepass flow on extension of the shock absorber additional to the normal damping action of a conventional valve assembly of the piston. In the construction shown in Fig. 1 (Prov.) a needle valve 13 controls flow between ports 14 and 15 leading between the upper and lower faces of the piston (not shown). The valve 13 is slidably mounted in a bronze bush 22 and has a soft iron head which co-operates with an electromagnet 12. The latter is supported by a flexible waxed ring 20 and a bronze sleeve 19. In the construction shown in Figs. 4, 5 flow between upper ,and lower faces of the piston is controlled by a rotary valve, Fig. 5 comprising a spindle 30 within the hollow piston rod 31 having an arcuate port 37 which cooperates with ports 36 opening above the piston. The port 37 is connected at 38 with a concentric port 39 which opens via a non-return ball valve, below the piston. The upper end of the spindle 30 carries a plurality of radially-disposed electromagnets 35 which function in the manner of a cogging motor. By the operation of a driver-controlled switch the spindle 30 may be rotated to connect selectively one or more of the ports 36 with the port 37.

Filed: 1929-03-19
Abstract: 308,354. Knorr-Bremse Akt.-Ges. March 22, 1928, [Convention date]. Compensating for wear.-In an automatic device for adjusting the brake shoes of a drum brake to compensate for wear, the operating cam for the shoes c comprises a cylindrical head or housing on the usual shaft and containing two pieces e the outer faces of which are in contact with the ends of the shoes while the inner faces are inclined and engage a pair of conical discs f respectively screwed on to right- and left-handed threaded portions of a bolt g secured to a ratchet disc i engaged by one end of a cranked lever m mounted on a fixed pivot L A spring n holds the lever in contact with the, disc i. If in applying the brake, the housing and the pieces e have to be turned sufficiently to cause a tooth on the disc i to slip over the end of the lever m, the disc is turned during the return movement relatively to the housing, thereby causing the discs f to be moved towards each other to displace the pieces e radially outwards. The Specification as open to inspection under Sect. 91 (3) (a) states that a hand wheel may be provided for adjusting the disc i. This subjectmatter does not appear in the Specification as accepted.

Abstract: 732,445. Optical testing apparatus. CUNY, B. E. A. M. April 8, 1952 [June 6, 1951], No. 8937/52. Class 97 (1). A device for testing centring, coaxiality and alignment in which an optical axis serves as a reference straight line and the divergencies of various points from the said axes can be observed, comprises a lens-reticle assembly and a plane mirror, the reticle being treated at the nodal point on the mirror side of the lens and the mirror reflecting light passing through the lens in the annular zone outside the part occupied by the reticle, and the lens-reticle assembly being movable along said axis perpendicular to the plane of the mirror. As shown, the lens O and reticle R are movable in a guide 9 perpendicular to a plane mirror M, the reticle being illuminated by a lamp L and transparent mirror T, and an image of the centre of the reticle being formed at A on the axis X deferred by the lens O and mirror M. A collimator comprising lens O<SP>1</SP> with a plane mirror M<SP>1</SP> at the rear focal point is located on the body to be tested, with the front focal point at the image A, whereby light is reflected back through the system to form an image of the reticle R upon itself for observation in an eyepiece Oc, the displacement of the image from the centre of the reticle giving a measure of the areal misalignment. In a modification the collimator O<SP>1</SP> M<SP>1</SP> is omitted and an image of the reticle is formed on a sighting mark on the axis to be measured, the sight and reticle being viewed through the eyepiece Oc, or through an eyepiece attached to the sighting mark, the eyepiece Oc being omitted.

Patent GB-887382-A (GB)
Title: Improvements in or relating to laminated rubber
IPC: B29C67/24
Filed: 1957-03-21
Abstract: 887,382. Laminates. BAXTER, D. G. H. March 21, 1958 [March 21, 1957], No. 9324/57. Class 140. A laminated rubber, suitable for use as soling material, comprises a layer of cellular rubber, an " intermediate layer " secured on one face to the cellular rubber layer, and a layer of crÛpe rubber secured to the other face of the " intermediate layer," the cellular rubber layer being completely vulcanized, the " intermediate layer " being partly vulcanized in the vicinity of the cellular rubber layer and the crÛpe rubber layer being unvulcanized. The cellular rubber is a natural, synthetic or reclaimed rubber or combination thereof, that has been rendered porous or spongy in the course of its manufacture, or is foamed. The " intermediate layer " is made from any natural raw rubber which, on treatment, is produced as a sheet which is hard with a substantial absence of internal stresses. The crÛpe rubber is raw unvulcanized single or multiple-ply sheets of pale crÛpe, brown crÛpe, smoked sheet or combinations thereof. It can be dyed, pigmented or compounded. Material for the cellular layer may be masticated on an open mill with a peptizing agent and softeners, there are then added fillers, a soap and a wax, sulphur and blowing agent, and the mix sheeted out. This is then doubled with a sheet of rubber for the " intermediate layer," and the combination rolled on to a hollow mandrel with a liner cloth. The combination is then vulcanized in an autoclave. During vulcanization, blowing of the cellular layer occurs and some sulphur migrates into the face of the " intermediate layer " next to the porous layer, and causes vulcanization thereof. The curing cycle is chosen so that the sulphur does not have time to penetrate throughout the " intermediate layer." After removal from the autoclave, this product is unwrapped from the mandrel and passed through rollers with crÛpe rubber. If this is done shortly after removal from the autoclave, the surface of the intermediate layer will be in a suitably sticky condition, otherwise the surface may be sprayed with solvent. In another method, the doubled rubbers are heated between the platens of a press instead of in an autoclave.
