Title: Improvements in or relating to Hydraulic Buffers or Shock Absorbers.
Inventor: HANCHEN SIEGFRIED
IPC: F16F9/48
Filed: 1967-03-17
Abstract: 1,185,511. Hydraulic buffers. S. HANCHEN. 17 March, 1967 [30 March, 1966], No. 12692/67. Heading F2S. An hydraulic buffer, for the deceleration of articles of large mass, e.g. heavy paper rolls, without recoil, comprises a piston-rod 12 which extends through an upper closure member 16 of a cylindrical chamber 13 and is connected to a piston 11 with a variable portion 20 which cooperates with a damping cylinder 27 which is formed in a lower closure member 14 for the chamber 13 and has transverse and axial bores 22, 21 extending therethrough and controlled by a ball valve 23, an auxiliary chamber 31 of variable volume formed in the lower closure member 14 and connected with the interior of the chamber 13 by a passage 30 of substantially greater cross-section than throttle bores 28, 29 which connect the damping cylinder 27 with the interior 9 of the chamber 13 and which are formed in the closure member 14 and controlled by a throttle valve 33, and resilient means, e.g. a spring 25, with relatively weak rebound force which tends to move the piston toward the upper closure member 16. The chamber 31 is sealed by a cover plate 32 having a gas filling screw 35, and accommodates a sealed bladder, or rolled diaphragm 34. The spring 25 is located between a piston centring ring 26 and the lower closure member 14. The strength of the spring 25, with that of the pneumatic bladder, or diaphragm, 34 is only just sufficient to overcome the mechanical and hydraulic frictional resistances in order to return the piston to its upper, inoperative, position after a compression stroke and after the body to be checked has been removed from contact with a pistonrod shock-absorbing member 36. The latter includes a strong resilient disc 39, made e.g. of polytetrafluorethylene. The piston has a tapered leading end 20, the ball 23 being retained in a cavity in the valve piston 11 by means of a closure disc 24 having through bores. When a mass to be arrested strikes the member 36 the valve 23 closes and hydraulic liquid is forced past end 20 of the piston 11 into and also through the throttled bores 28, 29, into the chamber 9, compensating liquid passing through the duct 30 into the chamber 31. As the piston penetrates further into the cylinder 27 liquid passes to the chamber 9 only through the bores 28, 29. A stop is provided when the piston meets the base of the cylinder 27. When the mass is removed from the member 36 the spring 25 and the pneumatic bladder or diaphragm 34 return the piston to its upper inoperative position, the valve 23 opening to allow a quick and easy return flow of liquid into the cylinder 27. The converging part 20 of the piston may extend over any desired axial length of the piston 11 and it may be conical, curved, or provided with graduations. The throttle 33 can be replaced by a flow-regulating valve under the influence of the viscosity of the hydraulic liquid, and the bladder, or diaphragm, may be filled with gas at normal or overpressure.

Title: Improvements in or relating to electric resistance control devices
IPC: H01C10/18
Filed: 1923-05-14
Abstract: 197,697. Wiegand, H. J. May 15, 1922, [Convention date]. Variable resistances; sets of resisiances.-In a resistance control device comprising two resistors having two relatively rotatable ccntactors engaging therewith respectively, the main resistance is in the form of a helically coiled wire and the other, which acts as a vernier adjustment is non-twisted, so that equal amounts of rotation produce less change in the vernier resistance in circuit than in the main resistance. In the form shown in Figs. 1 and 2, the helically coiled resistance element 22, on which bears a contact 31, is carried on an insulating annulus 21 between flanged endplates 19 secured to a hub 14, through which passes the tubular operating shaft 15. A setscrew 16 is provided for angular and axial adjustment of the hub with respect to the shaft. The vernier resistance 38 is carried on an insulating annulus 37 secured to a hub 39, which is adjustably secured to an operating shaft 41 passing through the tubular shaft 15. A projecting insulating link 23, to which the ends of the resistance 22 are attached, is located in the annulus 21 and causes the contact blade 31 to lift when the resistance limit is reached. The resistance wire is electrically connected to one of the end plates, the circuit being completed through the hubs by means of a spring clip 45, Fig. 1<a>, which also serves to bias the shafts 15 and 41 axially in opposite directions. The contact blades 31 are mounted on adjustable insulating sleeves 29, 30 carried by a bolt, 28, and are provided with terminals 35. Lugs 25, 26 limit the relative rotary movement between the resistance elements and contact blades. The Specification as open to inspection under Sect. 91 (3) (a) also includes the following modifications. In the construction shown in Fig. 4 (Cancelled), the vernier resistance is not employed, and a set-screw 16<a> penetrates the annulus 21a, its head lying in a countersunk insulating spacer 47 which may function like the projection 23 described above. The frame comprises separable elements 11<a>, 12a, and a resilient cup washer 46, Fig. 3<a> (Cancelled), is used in place of the spring clip 45. In another construction, the vernier resistance may be mounted on the same insulating annulus, and the contact blades adjustably mounted on the respective operating shafts. This subject-matter does not appear in the Specification as accepted.
