Abstract: 772,495. Resilient bearings: vehicle suspensions: bogies. SOC. APPLICAZIONI GOMMA ANTIVIBRANTI S. A. G. A. SOC. PER AZIONI. June 21, 1954 [June 19, 1953 ; Oct. 6, 1953], No. 18170/54. Classes 103(6), 108(2) and 108(3). ' Resilient guide means, for the relatively moving parts of a system such as a suspension for an axle bearing or a bogie of a vehicle, comprises resilient rollable elements squashed between guide surfaces on the guiding and guided members, the guide surfaces being parallel to the linear path of relative motion between the members, and the rollable elements being arranged in planes normal to the guide surfaces and being separated from elements in adjacent planes by means of separator elements. Fig. 1 shows an axle suspension in which the guide surfaces are defined by a post 1 working coaxially in a cylinder 2, the rolling elements consisting of annular rubber rings 3 compressed between the post and cylinder. The cylinder 2 may be replaced by a square box with which each ring 3 has four point contact. Furthermore, another cylinder rigid with the post 1 may contain another set of rings 3 that roll on the outside of the cylinder 2. A square post may be used to reciprocate in a square box, the opposed faces of the post and box having separate cylindrical rollers compressed between them. The rings 3, or like elements, are separated by plates 4 having a low coefficient of friction with the rings. Alternatively the rings may be separated by freely rolling balls, or by balls or rollers threaded onto a wire ring, or by a helically wound wire ring.

A spinning spindle bearing assembly comprises a blade 16 mounted in a fixed tubular bolster 10 by spaced bearings 17, 18 located below and above a spindle rail 11, a driving wharve 19 fixed to the blade and a cup-like reservoir 25 in which the lower bearing 17 is enclosed and from which lubricant is propelled through the hollow interior of the bolster 10 to the upper bearing 18, the reservoir 25 being connected to the blade 16 so as to rotate therewith. The bolster 10 is supported in the spindle rail 11 by a resilient bush comprising two coaxial metal tubes 12, 121 having a cylindrical rubber member 13 therebetween. The outer tube 12 has a flange 112 engaging a washer 14 and has an externallythreaded portion 212 which is engaged by a nut 15, the tightening of which clamps the bolster to the rail 11. The wharve 19 is secured by split conical bushes 20, 21 seated in axial conical recesses therein and being tightened by nuts 22 at the upper end of the blade, the bush 21 also abutting the bearing 18 so as to clamp it to the blade 16. A scoop 27, loosely mounted on the blade 16, projects through an aperture 101 in the bolster 10 and into the cup 25. The rotating oil in the cup 25 is collected by the scoop 27 and is forced up the bore of the bolster 10 to the upper bearing 18. The scoop 27, Fig. 2 has two oppositely-curved spaced arms 271, 272 so that oil is conveyed in either direction of rotation of the blade. A rubber washer 28 may be fitted to the bolster 10 above the scoop 27 to deflect oil downwardly and a lid 26 covers the reservoir 25. A package carrier 23 is carried at the bottom of the spindle. In another embodiment, the carrier 23 is carried at the top of the spindle, Fig. 3, and the bolster 10 is supported by a seating member 30 having a flange 301 engaging the rail 11. Specification 723,470 is referred to.
Patent GB-182103-A (GB)
Abstract: 182,103. Siemens & Halske Akt.-Ges. June 21, 1921, [Convention date]. Automatic and semi-automatic exchange systems.-Relates to sytems in which incoming calls over trunk lines are extended by operators over numerical selectors to local lines. Each trunk line F terminates at the semi-automatic exchange in two common lines SL1, SL2, each having two or more branches I, II, III, IV &c. The local operator calls the wanted subscriber over one branch and tells him he will be wanted soon for a trunk call. The subscriber then hangs up but the connection is not released, being subsequently switched through to the trunk line under control of the operator at the outgoing end of the trunk. The trunk line is connected alternately by a polarized relay M to the two lines SL1, SL2, and the branch lines I, II, III are switched through to the common line SL1 in the order in which they are used to warn the wanted subscribers. Assuming that the first call is to be extended over branch I to subscriber Tn, the operator depresses key T1, thereby connecting up her sending and speaking set and energizing relays An1, E1. The pre-selector VW finds an idle selector and its test relay P locks up under control of relay E1. The wanted line is selected in the usual manner, and when the sender reaches normal the ringing-generator Ru is connected up. When the subscriber replies, relay S cuts off the ringing-current and the operator informs the subscriber that he will soon be wanted for a trunk call. The subscriber replaces his receiver, but the connection is retained since relay P is under control of relay E1. If the operator has called the wrong line, she can release the connection by pressing key TrT1. The operator then releases key T1 and sets up other calls in a similar manner over other branches of lines SL1, SL2 alternately. To establish the trunk call, the outgoing operator connects positive potential to the a-lead of the trunk line, thereby energizing the polarized relay M, which connects the trunk to the line SL1 and energizes relays R, V. Relay R connects up the ringing-generator Ru1, which is out off when the relays Y, U, Ab energize on the response of the called party. When the called party hangs up, the relays Y, U deenergize, momentarily connecting battery B to the relay Q which connects a generator Ru2 to the trunk line to give the clearing signal. To establish the next trunk call, the trunk operator reverses the current on the line, causing relay M to connect the trunk to line SL2 to a branch of which the local line has been connected. The relay M also open-circuits relays R, V, thereby momentarily opening the holding-circuit of relay E1, which (1) disconnects branch I from line SL1, (2) opens at 58 the circuit of relay P to release the local connection, and (3) closes at 51 the circuit of relay E2 to connect up the branch II on which a further local connection has been set up.

Abstract: 497,952. Inclinometers; gyroscopic apparatus. SOC. CIVILE D'ETUDES DE CONSTRUCTIONS AERONAUTIQUES E. C. A. June 30, 1937, No. 18231. Convention date, June 30, 1936. [Classes 97 (ii) and 97 (iii)] A gyroscope is used to counteract the effects of centrifugal force on a pendulum and the mass of the latter is formed by the liquid of a liquid pressure gauge subject to a partial vacuum created by the speed of the supporting craft so that the effective length of the pendulum varies inversely as the speed and the gyroscopic couple due to turning counteracts the centrifugal force at all speeds and rates of turning. As shown in Fig. 2, the suction at the throat of a Venturi tube 50 is applied through the pivot axis to the interior of a hollow pendulum and is utilized to draw mercury from the vessel A through the aperture 54 into the hollow stem B. In this way, the centre of gravity may be automatically raised, e.g. from G to G<1>. The gyroscope may be mounted to spin about a transverse axis in the pendulum. As shown in Fig. 4, the gyroscope 3 spins in a precession frame 8 which is connected by links 20, 23 to one end of a bellcrank lever 35. A representation of an aircraft 26 is pivoted at the other end of the bellcrank lever 35 and is connected by pin-andslot mechanism 28, 29 to the pendulum 1 which carries an indicating disc 31.

Title: Improvements in or relating to the production of porous compositions
IPC: C08L21/00
Filed: 1936-07-02
Abstract: Porous hard rubber is produced by incorporating sulphur with a p rubber composition in excess of that required to form hard rubber and after vulcanization removing the excess free sulphur with perhaps other ingredients of the mix.  The amount of sulphur varies in examples from 4 to 5 or more times the amount of rubber. The rubber is microporous and the process may be applied jointly with other processes for making porous rubber as, e.g. vulcanization of a wet mix, the incorporation of fibres or threads, wet or hydrated fillers, or gas bubbles, as by blowing or frothing.  The sulphur solvent may be carbon disulphide, benzene, white spirit or alkali hydroxide.  In an example a 2 per cent solution of sodium thiosulphate is used as a lubricant for a vulcanizing mould.  Articles such as diaphragms or tubes for electrical, diffusion, or filtration purposes may be made of the porous ebonite so produced.
