Title: Improvements in Chains.
Inventor: WIRTZ LUIS
IPC: F16G13/10
Filed: 1917-03-19
Abstract: 114,037. Wirtz, L. March 19, 1917. Driving and like chains without separate joint pins.-In a chain in which links in the form of shank-like members with ball or like ends connect tubular or other links, the latter are of a jointed character permitting a degree of free movement in at least two directions. Further, the chain is built up without the use of rivets or screws. The flexible links comprise cup members c fitted with liners d to receive the ball ends of the shank links a. The liners d may be of soft or non-corrosive material, and are slit to enable them to be opened for positioning them on the links a. The liners d and cups c may be pressed from flat blanks, and the cups c have lugs h with longitudinal slots j. Two cups c are placed with their lugs together, but preferably in planes at 90 degrees, and are connected by wires or staples passed through opposite slots j and engaged by a surrounding wire, or by linked bridge-pieces c with projections m engaging the slots. The link may be enclosed in a rubber or like sleeve, or in a spring o which may be itself enclosed, and is preferably engaged by the lugs m or by other lugs arranged to compress the spring when the link is extended. The lugs may engage notches to anchor the spring, or the ends of the latter may be closed preferably by pressing against a concave grinding-disk which anneals the part without affecting the body of the spring. In a connecting- link, Fig. 11, the liners d are slotted so that they may be rotated in the cups c to disengage the shank links a. Dished members r, connected by a link t and detachably secured to the cups c by split pins s, form abutments for springs q which normally hold the liners in operative position. The chain may be used to give a frictional drive. Specifications 24141/14 and 11413/15 are referred to. The Provisional Specification also states that the cup members may have thickened or flanged rims around the apertures or the shank members, or may be mounted in curved mushroom-like caps perforated to receive the shank members.

Title: Improvement in the manufacture of plastic products from waste rubber
IPC: C08J11/08
Filed: 1943-03-18
Abstract: Waste rubber is heated with a solvent or mixture of solvents to obtain a solution which is then cooled to 0 DEG  C. or below and reacted with hydrogen chloride, the treatment being carried out substantially out of contact with the air, to produce a plastic substance which can be used for making transparent elastic, and acid and alkali resisting film, impregnating paper, board, or fabric, as an adhesive or lacquer, or for vulcanizing.  The rubber waste, preferably comminuted, is submerged in a solvent boiling at about 100 DEG  C. and is heated for several hours, preferably at 130-170 DEG C., the liquid being stirred or circulated during the treatment which is carried out in the absence of light and air and, if desired, in an inert atmosphere.  The solution is then cooled to a temperature of from 0 DEG  to -30 DEG  C., and hydrogen chloride is bubbled through for a period inversely dependent on the temperature.  At the completion of the reaction and the removal of the excess hydrogen chloride, there should be 17-25 per cent combined chlorine in the product.  Plasticizers, stabilizing and anti-aging agents, pigments, dyes and fillers may be incorporated.  Specification 474,841 is referred to.

Title: Improvements in and relating to distributor devices for liquid fuel burners, more especially burners for readily volatile fuel such as petrol
IPC: F23D11/04
Filed: 1957-02-12
Abstract: 811,809. Liquid fuel burners. BAIER, O., BAIER, L., BAIER, W., BAIER, W., SCHLUMPRECHT, E., and BAIER, W., [trading as BAIER K.G. W.]. Feb. 12, 1957 [March 21, 1956], No. 4803/57. Class 75(1) In a burner for liquid fuel, especially volatile fuel such as petrol, having a rotary atomizer, a stationary intermemediate vessel is provided in the immediate proxim i t y of the atomizer and has two or more outlets at different heights. Interruption of the fuel supply by temporary obstruction of the fuel pipe e.g. by bubbles, is thereby prevented. In one form, fuel is pumped through a pipe 11 to an intermediate vessel 10 having two outlet pipes 13, 14 one above the other which deliver fuel to a distributer dish 2 having atomizing tubes 3. 4, at opposite ends of a diameter. The dish 2 is mounted with an impeller 6 on a rotary shaft 1. One of the tubes 3, 4 may be located nearer to the centre of the dish than the other. In the event of temporary cessation of the fuel supply, delivery of the fuel remaining in the vessel 10 takes place through the outlet 14. To avoid passage of air bubbles into the outlet pipes 13, 14, the pipe 11 may be offset from the vertical plane through the axes of these pipes. In a modified form, the vessel 10 is fed from above and the tubes 13, 14 end close to the front wall of the distributer dish e.g. with a gap not greater than 1.5 mm. In a further modification the intermediate vessel is the form of an annulus whence fuel passes by way of two vertically arranged ports to a cup within and close to the front wall of the distributer dish.

Title: Acoustic thermometers
Inventor: BELL JOHN FREDERICK WILLIAM
IPC: G01K11/26
Filed: 1969-01-29
Abstract: 1,246,542. Acoustic thermometer. J. F. W. BELL. 27 Jan., 1970 [29 Jan., 1969], No. 4934/69. Heading H4D. In an acoustic thermometer comprising an acoustic transmission line along which ultrasonic pulses are conveyed to and from an acoustic resonator disposed in a region whose temperature is to be sensed, electronic means automatically vary the ultrasound carrier frequency to maintain resonance in the resonator as the temperature of the resonator varies. As shown in Fig. 1, magnetostrictive transducer 3 is silver-soldered or welded to a line 5 having at one end an isolator 1 and reflector 2 and at the other end a coupler 6 and acoustic resonator 7. Line 5 may be supported in loose (low acoustic impedance) mounts to avoid spurious echoes. A transmitted burst of oscillations of envelope a (Fig. 2) gives rise to an echo of envelope b which at resonance has a crossover region, the oscillations before the crossover being 180 degrees outof-phase with those after the crossover. A control loop error signal for varying the carrier frequency of the oscillation source to maintain resonance is derived by establishing early and late time gates c, d, each embracing a few oscillation cycles near the crossover; deriving a reference square wave R and its inverse R (Fig. 3), both synchronous with the carrier frequency; squaring-up the echo signal to give a signal S; applying signals S, R and c to an AND gate to give a first output representing the overlap of R and S before crossover; applying signals S, R and d to a second AND gate to give a second output representing the overlap of R and S after crossover; summing the first output and the inverse of the second output; and integrating the summation result. The locked resonance frequency is indicated digitally, and a frequencyto-temperature conversion circuit may feed a digital temperature indicator. Several acoustic resonators used in turn may be connected to the frequency-maintaining and measurement circuitry. Reference waves R and R may be derived by phase-shifting and squaring an output of the carrier frequency source, or, particularly if acoustic transmission lines of different length are used, from an oscillation burst triggered by the onset of the echo signal. Materials for the transmission line and resonator are specified. The thermometer may be used for automatically controlling furnace temperature. Reference has been directed by the Comptroller to Specification 1,146,520.

Title: Improvements in and relating to the separation of oil from bleaching clay
IPC: B01J20/12
Filed: 1930-02-14
Abstract: Mineral oil is recovered from used bleaching clay by boiling the clay with dilute mineral acid under pressure.  The mechanically mixed oil as distinct from that adsorbed may first be removed by organic solvents, e.g. petrol, benzol, or trichlorethylene.  For example, 1 kg. of used bleaching clay containing 30 per cent of oil is extracted with 3 separate litres of hot petrol; 200 grams of oil are removed, which after distilling off the petrol, are added to another batch of the oil to be purified.  The clay is then agitated in a closed vessel with 1 litre of 30 per cent sulphuric acid while steam is blown in until the pressure reaches 3 atmospheres.  The mass is allowed to stand for 3 hrs., the oil layer is withdrawn and the petrol distilled off; 100 grams of dark-coloured oil remain.
