Title: Improvements relating to telephone systems
IPC: H04Q1/32
Filed: 1934-03-08
Abstract: 427,841. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Tothill Street, DIXON, R. G., 162, Westmount Road, Eltham Park, and CLARK, R. I. H., 65, Humber Road, Blackheath, all in London. March 8, 1934, No. 7407. Addition to 372,004. [Class 40 (iv)] In a feed circuit, for example, a repeater as shown, having a ballast resistance FR for use with lines of varying length as described in the parent Specification, the impulse relay A has two windings which are normally connected in parallel but during impulsing are connected in series in order to increase the effective ampereturns. On seizure of the repeater, relay A operates either over the incoming loop or over the b-wire to ground. In the latter case, relay P does not operate and a discriminating ground signal is sent forward over the outgoing b-wire. Relays CA (i), B operate, the former changing over the windings of relay A from parallel to series connection, whilst relay B short-circuits winding CA (ii) to render it slow-releasing. At the first impulse, relay J (i) operates to complete the outgoing loop if not already closed by P, relay C (i) operates and shunts its winding (ii), and relay CA remains held over its winding (i) and contact c4. Impulses are repeated at contact a2 and at the end of the digit, relays C, CA release in succession and restore the normal connection of the windings of A, the time of release however being such that the low-impedance shunt across relays D, I will be maintained during the normal hunting time of the switch at the distant end of the outgoing junction. Further digits are similarly repeated, relays C, CA operating for each digit. When the called subscriber replies, relays D, DD, MD, operate releasing J which marks off a booster metering period. When the calling party hangs up, relays A, B release and C operates temporarily and holds MD (ii) to mark the repeater busy during release at the other end of the junction. If the wanted line is busy, a busy-flash signal is sent back over the junction, causing on the first release of relay I the unlocking of relay J, and on the subsequent energization of relay I the operation of BR to flicker lamp AL and to repeat back the busy signal. If the calling party delays release after the called party hangs up, lamp AL lights steadily, and release may be forced by the manual application of a short-circuit across the junction wires releasing relay I and causing busy-flash conditions to be set up. Specification 254,364, [Class 35], is referred to.

Title: Apparatus for cooling liquids and for optionally charging the same with carbonic anhydride
IPC: B01F3/04
Filed: 1924-03-28
Abstract: 232,026. Cremieu, V. March 28, 1924. Cooling-cartridges opened to produce cold; receptacles with cooling-means.-Liquid carbon dioxide is led from a container 3 through a pipe 1 into a thin-walled tube 6 surrounding the end part of the pipe 1 and secured thereto by an internally screw-threaded cap 5. The upper end of the tube 6 carries a wooden receptacle 9 having a side opening closed normally by filtering fabric 13 secured to a hinged frame 12. The tube 6 is immersed in the liquid 15 to be cooled. On opening the cock of the container 3 the liquid flows through the pipe 1, percolates through the screw-threads of the cap 5 and boils in the tube 6. The fall in temperature thus produced freezes the liquid, thus plugging the screw-threads and the tube 6 and stopping further escape of the carbon dioxide. To continue the cooling operation the receptacle 9 and tube 6 are oscillated on the pipe 1 to break the plug of solid carbon dioxide and let more liquid escape from the container. If it is desired to charge the cooled liquid with carbon dioxide the solid carbon dioxide which has collected in the receptacle 9 is removed and placed in the liquid. In the apparatus shown in Fig. 3, the carbon dioxide escapes through openings 23 in a cap 19 into the space under a hollow stopper 20. The increase in pressure lifts the stopper 20 closing the openings 23 and the only escape for the carbon dioxide, which is boiling within the cap, is through recesses 24 formed down the sides of the cap 19. The reduction of temperature consequent upon the boiling of the carbon dioxide causes it to freeze and to plug these recesses until sufficient heat has been extracted from the liquid to be cooled, which is contained in a cup 27 having a recess 26 in its bottom to take the stopper 20, to melt the solid carbon dioxide and to reduce the pressure in the stopper 20. The stopper then. falls and permits another escape of liquid and the process is repeated.

Filed: 1946-03-14
Abstract: 613,061. Weighing-apparatus fitted to concrete mixers. BELLAMY, E. A. March 14, 1946, No. 8016. [Class 143] Apparatus fitted to a concrete or like mixer for weighing-out the component materials, comprises a skip 6 pivotally mounted in a cradle 13 carried on weighing levers 8 suspended from a frame 1 which is hinged to the mixer so that the frame, together with the cradle and weighing mechanism, can be raised by the skip into a stowed vertical position for transport. Before weighing - out each charge of material, moreover, the skip is initially lowered to the ground, to avoid shock to the weighing mechanism, and is then raised clear for weighing. In the construction shown, the skip 6 is pivoted by lugs to brackets 14 on the cradle 13, and is raised about these pivots to discharge its contents into the mixer by a winch and rope (not shown) attached to the outer end of the skip. There are four transverse weighing levers 8 with shackle 9 and knife-edge connections with the skip cradle 13 and frame 1. The skip 6 when raised about its pivots normally clears the frame 1, but when the apparatus is to be stowed a cross-bar 32 is passed through brackets 31 on the frame and is intercepted by the skip when lifted so that the frame 1 and associated parts are lifted with it into a stowed vertical position against the side of the mixer. Brackets 33 on the frame 1 then take the weight of the cradle to relieve the weighing levers. When the skip is lowered about its pivotal connection 14 with the cradle to receive a fresh charge, its rear end passes clear of the cradle and into contact with the ground. It is then lifted to effect the weighing by means of a lift-bar 21 operable by a handle 20 through a pinion 19 and toothed quadrant 16. A catch 22 locks the quadrant 16 to hold the skip raised during weighing, and is struck clear again when the skip is lifted to discharge its contents by a lug 25 on the side of the skip.

Title: Process for the production of cyclodecan-6-ol-1-one
IPC: C07C409/14
Filed: 1963-02-28
Abstract: The parent Specification describes a process in which 6-hydroxycyclodecan -1- one is prepared from decalin peroxide by treatment with an acid. This process is now applied directly to a solution of the products obtainable by the oxidation of decalin with oxygen, without intermediate separation of the decalin peroxide, now defined as trans-decalyl -9- hydroperoxide. The process may be effected by dissolving or dispersing an acid in a solution of the oxidation products and separating the cyclodecane derivatives from the reaction product, e.g. by extraction with a chlorinated hydrocarbon. Specified acids are sulphuric, phosphoric, pyrophosphoric and perchloric acids. Mixtures of inoganic and organic acids may also be used, e.g. a mixture of sulphuric and acetic acids, and in that event the hydroxyketone may be partly converted into a ketonic ester, which may be saponified with caustic soda. Before the reaction with acid, the solution of decalin oxidation products may be treated with an ionexchanger or washed with an alkali, and a part of the unreacted decalin may be distilled off. The reaction mixture may contain a solution-promoter, e.g. acetone. Examples are given, including one example in which the process is effected continuously.
